Darüber hinaus betrifft die Erfindung eine Gebäudewand mit einem Stützgerüst, bestehend aus zumindest zwei im Abstand zueinander angeordneten, vorzugsweise lotrecht ausgerichteten Ständern, insbesondere in Form von G, U-, W- oder Ω förmigen Profilen aus Metall, einer zumindest einseitigen Verkleidung, vorzugsweise in Form von Gipskarton- und/oder Gipsfaser-Platten und einer Wärme- und/oder Schalldämmung aus einer Dämmschicht mit zwei großen Oberflächen.The invention relates to a mineral fiber insulating layer of adjacent insulating panels, which are installed between two spaced-apart building parts, wherein each insulating board consists of a mineral fiber body with two large parallel aligned, can be applied to the building components surfaces and these connecting side surfaces. Moreover, the invention relates to a building wall with a scaffold, consisting of at least two mutually spaced, preferably vertically oriented uprights, in particular in the form of G, U, W or Ω-shaped profiles made of metal, an at least one-sided panel, preferably in Form of plasterboard and / or gypsum fiberboards and a thermal and / or acoustic insulation consisting of an insulating layer with two large surfaces.

Aus dem Stand der Technik sind Gebäudewände und in diesen eingebaute Dämmschichten bekannt. Es handelt sich hierbei um nicht tragende innere Wände, die als Trennwände mit Flächengewichten bis zu 1,5 kN/m2 ausgebildet sind und im Unterschied zu aus Ziegeln, Steinen oder Porenbetonelementen unter Verwendung von Mörteln oder Klebermassen aufgebauten Wandkonstruktionen Montagewände genannt werden. Diese Namensgebung beschreibt bereits das Zusammenfügen der Komponenten im trockenen Zustand (Trockenbau) im Zuge einer Montage der einzelnen Komponenten.From the prior art building walls and built-in insulating layers are known. These are non-load-bearing inner walls, which are designed as dividing walls with basis weights of up to 1.5 kN / m 2 and are called assembly walls, in contrast to wall constructions made from bricks, bricks or aerated concrete elements using mortar or adhesive compounds. This naming already describes the assembly of the components in the dry state (drywall) in the course of assembly of the individual components.

Gattungsgemäße Gebäudewände werden überwiegend durch ihr Eigengewicht beansprucht und sind nicht in das statische Konzept eines Gebäudes integriert. Sie müssen allerdings auf ihre Fläche wirkende Kräfte aufnehmen und in die angrenzenden tragenden Bauteile einleiten. Verformungen der angrenzenden Bauteile dürfen nicht zu Zwängungsspannungen in den nicht tragenden Gebäudewänden führen, so dass diese Gebäudewände durch Bewegungsfugen von den angrenzenden Bauteilen zu trennen sind.Generic building walls are mainly claimed by their own weight and are not integrated into the static concept of a building. However, they must absorb forces acting on their surface and introduce them into the adjacent supporting components. Deformations of the adjacent components must not lead to constrained stresses in the non-load-bearing building walls, so that these Building walls are separated by movement joints of the adjacent components.

Gattungsgemäße Gebäudewände müssen bestimmte Anforderungen hinsichtlich des Schall-, Wärme- und Brandschutzes erfüllen. Insbesondere sollen hierbei hohe Schalldämmeigenschaften und zumindest eine Feuenividerstandsklasse F 30 nach DIN 4102 Teil 4 erzielt werden. Es sind aber auch Gebäudewände bekannt, die aufgrund entsprechender Feuerschutzkonstruktionen bis zu 180 Minuten einer Brandbeanspruchung widerstehen können und demzufolge als feuerbeständig mit einer entsprechend höheren Klassifizierung der Feuerwiderstandsklassen zu bezeichnen sind. Entsprechende Anforderungen an die Widerstandsfähigkeit der Gebäudewand im Brandfall führen aber dazu, dass bestimmte Baustoffe, insbesondere im Bereich der tragenden Konstruktionselemente nicht verwendet werden dürfen, wenn diese Baustoffe im Feuer ihre Standfestigkeit verlieren oder einen aktiven Beitrag zum Brandgeschehen leisten.Generic building walls must meet certain requirements in terms of sound, heat and fire protection. In particular, high sound insulation properties and at least one fire resistance class F 30 according to DIN 4102 Part 4 should be achieved. But there are also known building walls, which can withstand up to 180 minutes of fire stress due to appropriate fire protection structures and are therefore to be described as fire resistant with a correspondingly higher classification of the fire resistance classes. However, corresponding requirements for the resistance of the building wall in case of fire lead to the fact that certain building materials, especially in the field of load-bearing construction elements may not be used if these materials in the fire lose their stability or make an active contribution to the fire.

Hier in Rede stehende Gebäudewände, die aus metallischen Ständern und Gipskartonplatten bestehen, werden in DIN 18 183 beschrieben. Es wird zwischen Einfach- und Doppelständerwänden, sowie freistehenden Vorsatzschalen unterschieden. Nach der DIN 18 183 besteht eine Einfachständerwand aus einer in einer Ebene angeordneten Unterkonstruktion mit Ständern, die beidseitig mit Gipskartonplatten als Verkleidung beplankt sind. Bei der Doppelständerwand sind die Ständer in zwei parallelen Ebenen angeordnet und nur auf den beiden äußeren Seiten mit einer Verkleidung aus Gipskartonplatten beplankt. Freistehende Vorsatzschalen bestehen aus einer in einer Ebene angeordneten Unterkonstruktion mit Ständern und einer einseitigen Verkleidung aus Gipskartonplatten.Building walls in question, which consist of metallic uprights and plasterboard, are described in DIN 18 183. There is a distinction between single and double column walls, as well as freestanding facing shells. According to DIN 18 183, a single stud wall consists of a substructure arranged in a single plane with uprights covered with gypsum plasterboard panels on both sides. In the double column wall, the stands are arranged in two parallel planes and only covered on the two outer sides with a plasterboard cladding. Freestanding facing shells consist of a substructure with uprights arranged in one level and a one-sided cladding made of plasterboard.

Die Ständer werden nach ihrer Profilierung als C- oder U-Profile bezeichnet, wobei sich die C-Profile dadurch von den U-Profilen unterscheiden, dass die freien Enden ihrer Schenkel einfach oder doppelt aufeinander zu umbördelt sind. Ergänzend werden die Buchstaben "W oder "D" an die Buchstaben "C" bzw. "U" angehängt, wenn die Profile als Wandprofile (W) oder Deckenprofile (D) Verwendung finden. Die Umbördelung der freien Enden der Stege dient der Aussteifung der Profile, die alternativ oder ergänzend auch durch Sicken im Bereich des Steges oder aber auch im Bereich der Schenkel erzielt werden kann. Durch die Sicken wird ergänzend eine geringere Anlagefläche an den Verkleidungselementen erzielt, so dass sich die Schallenergie im Bereich der Kontaktflächen zwischen Verkleidung und Profil verringert. Alternativ können auf den Schenkeln außenseitig punktförmige Erhebungen angeordnet sein, um eine Distanz zwischen den Schenkeln und den Verkleidungselementen einzustellen.The stands are referred to their profile as C or U-profiles, whereby the C-profiles differ from the U-profiles in that the free ends of their legs are simply or twice flanged to each other. In addition, the letters "W" or "D" are appended to the letters "C" or "U" if the profiles are used as wall profiles (W) or ceiling profiles (D) Profiles which can alternatively or additionally also be achieved by corrugations in the region of the web or else in the region of the legs Contact surfaces between cladding and profile reduced. Alternatively, punctiform projections may be arranged on the legs on the outside in order to set a distance between the legs and the cladding elements.

Im Bereich der Sicken können darüber hinaus Kabel verlegt werden.Cables can also be laid in the area of the beads.

Die Profile werden auf dem Boden oder an der Decke mit Hilfe von eingedübelten Schrauben oder durch Drehstiftdübel befestigt. Die Drehstiftdübel trennen hierbei über eine zylindrische Kunststoffhülse den metallischen Kern von dem Profil, um die Weiterleitung von Körperschall zu reduzieren. Im Brandfall fixiert der Metallstift das Profil und damit die Gebäudewand auch dann noch, wenn der Kunststoff geschmolzen oder verbrannt ist. Vorzugsweise beträgt der Abstand zwischen den einzelnen Befestigungspunkten ca. einen Meter. In einer Gebäudewand ist üblicherweise ein Profil auf dem Boden und ein Profil an der Decke gegenüberliegend angeordnet, so dass sich eine lotrecht ausgerichtete Gebäudewand bereits dann ergibt, wenn die Verkleidungselemente an einem Schenkel des Deckenprofils und dem gegenüberliegenden Schenkel des Bodenprofils befestigt werden.The profiles are fixed to the floor or to the ceiling with the help of doweled screws or through dowel pins. The swivel dowels separate the metallic core from the profile via a cylindrical plastic sleeve in order to reduce the transmission of structure-borne noise. In case of fire, the metal pin fixes the profile and thus the building wall even if the plastic is melted or burnt. Preferably, the distance between the individual attachment points is about one meter. In a building wall, a profile is usually arranged on the floor and a profile on the ceiling opposite, so that a vertically aligned building wall already results when the cladding elements are attached to a leg of the ceiling profile and the opposite leg of the floor profile.

Zwischen den am Boden und an der Decke befestigten Profilen und den angrenzenden Bauteilen, beispielsweise dem Boden und der Decke müssen Dichtelemente eingesetzt sein, um sowohl einen schalldichten Abschluss als auch einen gegen Feuer und Rauch weitgehend dichten Abschluss zwischen den angrenzenden Bauteilen und der Gebäudewand aufzubauen. Entsprechende Dichtungen müssen kompressibel ausgebildet sein, um Unebenheiten der angrenzenden Bauteile bis zu einem gewissen Grad ausgleichen zu können. Demzufolge können sowohl kompressible Dichtbänder aus Schaumstoffen, Kitten oder sehr häufig Streifen aus Mineralwolle-Dämmstoffen in Dicken von ca. 10 bis ca. 20 mm eingesetzt werden.Sealing elements must be used between the profiles fixed to the floor and the ceiling and the adjacent components, for example the floor and the ceiling, in order to build both a sound-proof finish and a largely watertight seal between the adjacent building components and the building wall. Appropriate seals must be designed to be compressible to compensate for unevenness of the adjacent components to a certain extent. Consequently, both compressible sealing tapes made of foams, kitten or very often strips of mineral wool insulation materials in thicknesses of about 10 to about 20 mm can be used.

In die im Bodenbereich und an der Decke befestigten U-Profile werden lotrecht ausgerichtete Profile, sogenannte Ständerprofile eingesetzt, wobei die Schenkel dieser Ständerprofile in einer Gebäudewand im Wesentlichen eine gleich gerichtete Orientierung aufweisen, d.h., dass die Schenkel der Ständerprofile auf den Steg eines benachbarten Ständerprofils zu ausgerichtet sind. Ist ein Ständerprofil im Bereich eines angrenzenden Bauteils, beispielsweise einer tragenden Wand angeordnet, so wird dieses Ständerprofil in gleicher Weise an der tragenden Wand befestigt, wie die zuvor beschriebenen U-Profile im Bereich von Boden und Decke.In the U-profiles fixed in the floor area and on the ceiling, vertically oriented profiles, so-called stud profiles, are used, the legs of these stud profiles having essentially the same orientation in a building wall, ie the legs of the stud profiles on the web of an adjacent stud profile to be aligned. If a stand profile is arranged in the region of an adjacent component, for example a load-bearing wall, then this stand profile is fastened to the load-bearing wall in the same way as the previously described U-profiles in the area of floor and ceiling.

In der Regel werden die Ständerprofile reibschlüssig in den U-Profilen an Decke und Boden gehalten, wobei die Ständerprofile vom Steg des deckenseitig befestigten U-Profils mit Abstand angeordnet sind, um eine Relativbewegung der Ständerprofile zu den U-Profilen zu ermöglichen. Ergänzend können die Ständerprofile aber durch sogenannte Blindnieten miteinander verbunden werden, wenn Querriegel für Öffnungen oder sonstige Einbauten eingesetzt werden. Im Normalfall werden die Ständerprofile aber durch die Verkleidungselemente mit den deckenseitig und bodenseitig angeordneten U-Profilen fixiert.In general, the upright profiles are frictionally held in the U-profiles on the ceiling and floor, wherein the uprights are spaced from the web of the ceiling-mounted U-profile to allow relative movement of the uprights to the U-profiles. In addition, however, the uprights can be interconnected by so-called blind rivets when crossbars are used for openings or other installations. Normally, however, the upright profiles are fixed by the cladding elements with the U-profiles arranged on the cover side and on the bottom side.

Als Verkleidungselemente werden Gipskartonplatten in den Varietäten Gipskartonbau-(GKB) oder Feuerschutzplatten (GKF) oder Gipsfaserplatten verwendet. Derartige Platten sind mit unterschiedlichen Materialstärken und mit Längen zwischen 2000 und 4000 mm bei einer Abstufung von 250 mm bekannt, wobei die Breite derartiger Platten mit 1250 mm konstant ist. Bei Materialstärken von mehr als 18 mm ist die maximale Länge derartiger Platten auf 3500 mm begrenzt, wobei diese Platten mit Breiten von 600 mm oder 1250 mm angeboten werden. Aufgrund der Abmessungen der Platten und der bevorzugten hochkant ausgerichteten Einbaulage hat sich ein Abstand zwischen benachbarten Ständerprofilen von 62,5 cm als besonders vorteilhaft erwiesen, so dass die Platten mit ihren beiden Längsrändern an zwei Ständerprofilen und ergänzend mit dem Mittelbereich an einem dritten Ständerprofil befestigt sind. Verbunden werden die Platten mit den Ständerprofilen durch Schnellbauschrauben gemäß DIN 18 182, Teil 2 "Zubehör für die Verarbeitung von Gipskartonplatten - Schnellbauschrauben".As cladding elements plasterboard in the varieties gypsum plasterboard (GKB) or fire protection boards (GKF) or gypsum fiber boards are used. Such plates are known with different thicknesses and with lengths between 2000 and 4000 mm in a gradation of 250 mm, the width of such plates with 1250 mm is constant. For material thicknesses greater than 18 mm, the maximum length of such plates is limited to 3500 mm, these plates being offered with widths of 600 mm or 1250 mm. Due to the dimensions of the plates and the preferred upright mounting position, a distance between adjacent column profiles of 62.5 cm has proven to be particularly advantageous, so that the plates are fixed with its two longitudinal edges on two upright profiles and complementary to the central region on a third upright profile , The panels are connected to the frame profiles by drywall screws in accordance with DIN 18 182, Part 2 "Accessories for the processing of gypsum plasterboards - Drywall screws".

Der Hohlraum zwischen benachbarten Ständerprofilen einerseits und den Verkleidungselementen andererseits wird durch Dämmschichten ausgefüllt, die üblicherweise aus einzelnen Dämmplatten mit großer Steifigkeit bestehen. Diese Dämmplatten werden einerseits zwischen die Schenkel eines Trägerprofils eingeschoben, bis die Schmalseiten der Dämmplatten an dem Steg innenseitig anliegen. Andererseits werden die Dämmplatten mit ihrer gegenüberliegenden Schmalseite an die Außenseite des Steges des benachbarten Ständerprofils angelegt. Das Ausfüllen der Hohlräume mit einzelnen Dämmplatten führt zwar zu hervorragenden Dämmergebnissen, stellt aber aufgrund der Montage der relativ steifen Dämmplatten zwischen den Schenkeln der Trägerprofile eine aufwendige und gegebenenfalls unzureichend durchgeführte Arbeit dar. Vorzugsweise besteht die Dämmschicht aus zumeist leichten Faserdämmstoffen mit geringem längenspezifischen Strömungswiderstand, niedriger dynamischer Steifigkeit (S' in MN/m3) und hohem Schallabsorptionsvermögen. Die Dämmschicht wird klemmend zwischen den Profilen eingebaut.The cavity between adjacent stator profiles on the one hand and the cladding elements on the other hand is filled by insulating layers, which usually consist of individual insulation boards with high rigidity. These insulation boards are inserted on the one hand between the legs of a carrier profile until the narrow sides of the insulation boards bear against the web on the inside. On the other hand, the insulating panels are applied with their opposite narrow side to the outside of the web of the adjacent stand profile. Although the filling of the cavities with individual insulation boards leads to excellent Dämmergebnissen, but due to the installation of relatively stiff insulation boards between the legs of the support profiles is a complex and possibly insufficiently performed work. Preferably, the insulating layer consists of mostly lightweight fiber insulating materials with low length-specific flow resistance, low dynamic stiffness (S 'in MN / m 3 ) and high sound absorption capacity. The insulating layer is installed by clamping between the profiles.

Für die Dämmschicht verwendete Faserdämmstoffe müssen nicht brennbar gemäß DIN 4101 Teil I ausgebildet sein. Überwiegend werden Glaswolle-Dämmfilze, sowie Glaswolle- und/oder Steinwolle-Dämmplatten verwendet. Für Gebäudewände, die Brandschutzkonstruktionen nach DIN 4102 Teil 4 darstellen sollen bzw. eine hohe Feuerwiderstandsklasse haben, werden Steinwolle-Brandschutzplatten mit einem Schmelzpunkt gemäß DIN 4102 Teil 17 ≥ 1000° C in definierten Rohdichten mit zumeist verringerten Anteilen organischer Bindemittel in den entsprechenden Dicken verwendet. Trennwand-, Akustik- und Brandschutzplatten werden üblicherweise mit den Abmessungen 1000 mm X 625 mm angeboten und verarbeitet. Die Rohdichte normaler Akustikplatten beträgt in Abhängigkeit der angestrebten Wärmeleitfähigkeit Ca. 27 bis Ca. 35 kg/m3. Bei Brandschutzplatten liegen die Mindestrohdichten bei 30, 40, 50 oder 100 kglm3, wobei Materialstärken von 40 bis 100 mm eingebaut werden. Die Rohdichten sind hierbei abhängig von den Anforderungen hinsichtlich der Brandsicherheit.Fiber insulating materials used for the insulating layer must not be made flammable in accordance with DIN 4101 Part I. Mostly glass wool insulation felts, and glass wool and / or rock wool insulation boards are used. For building walls that are to represent fire protection structures according to DIN 4102 Part 4 or have a high fire resistance class, rockwool fire protection boards are used with a melting point according to DIN 4102 Part 17 ≥ 1000 ° C in defined densities with mostly reduced levels of organic binder in the appropriate thicknesses. Partition wall, acoustic and fire protection panels are usually offered and processed with the dimensions 1000 mm X 625 mm. The gross density of normal acoustic panels is approximately. Depending on the desired thermal conductivity Ca. 27 to approx. 35 kg / m 3 . In the case of fire protection boards, the minimum apparent densities are 30, 40, 50 or 100 kglm3, with material thicknesses of 40 to 100 mm being installed. The gross densities depend on the requirements with regard to fire safety.

Die Breiten der Akustikfilze bzw. Dämmplatten stimmen exakt mit den regelmäßigen Abständen der lotrecht verlaufenden Profile überein. Zu berücksichtigen ist, dass die nominellen Breitenmaße der Dämmstoffelemente durch Abmaße verringert sein können. Beispielsweise sieht DIN 18 165 Teil 1 zulässige Abweichungen von den Nennmaßen der Länge und der Breite von ± 2 % vor. Derartige Abweichungen kommen in der Praxis zwar selten und nur bei fehlerhaften Produktionen vor, führen aber bei einer Verwendung dieser Dämmstoffelemente zu einem Fehlen des klemmenden Einbaus der Dämmstoffelemente zwischen den Profilen. Fehlt das hierfür erforderliche Übermaß der Dämmstoffelemente, so entstehen durchlaufende Fugen in der Dämmschicht, die mitunter unentdeckt bleiben und dann zu einer verminderten Wärme- bzw. Schalldämmung führen.The widths of the acoustic felts or insulation panels exactly match the regular intervals of the vertically extending profiles. It should be noted that the nominal width dimensions of the insulating elements may be reduced by dimensions. For example, DIN 18 165 Part 1 provides permissible deviations from the nominal dimensions of length and width of ± 2%. Although such deviations occur in practice rarely and only in faulty productions, but lead to a lack of clamping installation of the insulating elements between the profiles when using these insulation elements. Missing the required oversize of the insulating elements, so arise continuous joints in the insulating layer, which sometimes remain undetected and then lead to a reduced heat or sound insulation.

Um die hiermit verbundenen Probleme auszuschließen ist es übliche Praxis, die Dämmstoffplatten quer zur Längsachse abzulängen, d.h. maßgenau auf den Einbau vorzubereiten. Diese Praxis führt aber zu einem zusätzlichen Arbeitsgang des Beschneidens der Platten und zu erheblichen Abfallmengen, da es zumeist nicht gelingt, die einzelnen Abschnitte wieder zu einem funktionierenden Dämmstoffelement der Dämmschicht zusammenzusetzen. Die Dämmstoffelemente werden zwischen die Schenkel der Profile gepreßt. Diese Tätigkeit ist sehr mühsam, weil zum einen evtl. Umkantungen der Schenkel und insbesondere die Schraubenspitzen der bereits einseitig montierten Verkleidung Hindernisse bilden, deren Überwindung darüber hinaus zu Beschädigungen der Dämmschicht, aber auch zu einer nicht unerheblichen Verletzungsgefahr für die Hände der handhabenden Arbeiter darstellen. Andererseits steifen insbesondere die Schrauben aber auch Befestigungselemente für die Dämmschicht dar, soweit die Dämmschicht auf die Schrauben aufgespießt bzw. aufgehängt werden, so dass auch die bereits erwähnten Akustikfilze verwendet werden können. Um die Verletzungsgefahr zu reduzieren, werden diese Arbeiten sehr vorsichtig und somit langsam durchgeführt. Neben dem damit verbundenen geringen Arbeitsfortschritt stellt sich ergänzend auch ein mitunter mit Mängeln behaftetes Arbeitsergebnis dar, wobei die Mängel insbesondere im Bereich der Profile nicht unmittelbar zu erkennen sind.In order to exclude the problems associated therewith, it is common practice to cut the insulation boards transversely to the longitudinal axis, ie to prepare accurately to the installation. However, this practice leads to an additional operation of trimming the plates and to considerable amounts of waste, since it is usually not possible to reassemble the individual sections to form a functioning insulating element of the insulating layer. The insulating elements are between the Legs of the profiles pressed. This activity is very cumbersome, because on the one hand possibly edging of the legs and in particular the screw tips of the already one-sided fairing form obstacles whose overcoming represent beyond damage to the insulating layer, but also to a significant risk of injury to the hands of the handling workers. On the other hand, in particular the screws but also fasteners for the insulating layer stiff, as far as the insulating layer are skewered or hung on the screws, so that even the aforementioned acoustic felts can be used. To reduce the risk of injury, this work is carried out very carefully and thus slowly. In addition to the associated low work progress is in addition also a sometimes fraught with defects work results, the deficiencies are not immediately apparent, especially in the field of profiles.

Bei Abständen zwischen den Profilen, die geringer sind, als die Breiten der Dämmstoffelemente, besteht die Möglichkeit, die in die Profile einzusetzenden Ränder der Dämmstoffelemente aus dünnen und kompressiblen Glaswolle-Platten auszubilden, die aufgrund ihrer Kompressibilität in einfacher Weise umgeschlagen und in die Profile eingedrückt werden können, so dass sich hieraus eine vollständige Ausfüllung des Profils ohne die zuvor beschriebenen Verletzungsrisiken ergibt. Diese Vorgehensweise hat aber hinsichtlich der Anforderungen an die Genauigkeit der Verarbeitung der Dämmstoffelemente Nachteile, da der Kompressionsgrad der einzelnen Dämmstoffelemente, insbesondere Dämmstoffplatten unterschiedlich ist, so dass die Dämmstoffplatten unterschiedlich tief in die Profile eingesteckt werden und gegebenenfalls nicht mehr vollflächig am Steg des gegenüberliegend angeordneten Profils anliegen.At intervals between the profiles, which are smaller than the widths of the insulating elements, it is possible to form the edges of the insulating elements to be used in the profiles of thin and compressible glass wool plates, which easily folded over because of their compressibility and pressed into the profiles can be, so that this results in a complete completion of the profile without the injury risks described above. However, this approach has disadvantages in terms of the requirements for the accuracy of the processing of the insulating elements, since the degree of compression of the individual insulating elements, in particular insulation boards is different, so that the insulation boards are inserted at different depths in the profiles and optionally no longer full surface on the web of the oppositely disposed profile issue.

Nachdem der Hohlraum zwischen den Profilen ausgefüllt ist, wird die Verkleidung ergänzt. Nach dem Verschließen der Gebäudewand mit der auf der zweiten Seite anliegenden Verkleidung liegt die Dämmschicht zumeist in einer zufälligen, selten in der vorgesehenen Position zwischen den Verkleidungselementen, wobei die Dämmplatten in der Regel eine geringere Dicke aufweisen, als der lichte Abstand zwischen den Verkleidungselementen auf den beiden Schenkeln der Profile.After the cavity between the profiles is filled, the cladding is supplemented. After the closure of the building wall with the adjacent to the second side panel, the insulating layer is usually in a random, rarely in the intended position between the cladding elements, the insulation boards usually have a smaller thickness than the clear distance between the cladding elements on the two legs of the profiles.

Eine Mineralfaser-Dämmschicht aus Dämmstoffbahnen oder Dämmplatten ist beispielsweise aus der DE 197 34 532 A1 bekannt. Jede Dämmstoffbahn oderA mineral fiber insulation layer of insulation webs or insulation boards is for example from the DE 197 34 532 A1 known. Any insulation web or

Dämmplatte besteht aus einem Mineralfaserkörper mit zwei großen parallel zueinander ausgerichteten, an den Gebäudeteilen anlegbaren Oberflächen und diese verbindende Seitenfläche, wobei der Mineralfaserkörper aus drei sandwichartig angeordneten Schichten aus Mineralfasern besteht.Insulating board consists of a mineral fiber body with two large parallel aligned, can be applied to the building parts surfaces and this connecting side surface, wherein the mineral fiber body consists of three sandwiched layers of mineral fibers.

Darüber hinaus offenbart die US 3,712,846 ein Schalldämmelement, welches aus einer mittleren Mineralfaserplatte und zwei außenseitig von dieser Mineralfaserplatte angeordneten Mineralfaserelementen besteht, wobei die Mineralfaserelemente eine gegenüber der mittleren Mineralfaserplatte erhöhte Rohdichte aufweisen. Auf den beiden Mineralfaserelementen ist ergänzend eine Deckschicht angeordnet, die eine aufgeraute Oberfläche hat. Die Deckschicht besteht aus einem Trägerelement in Form eines Gewebes, das aus einem geeigneten Material ausgebildet ist und mit einem geeigneten Elastomer imprägniert ist. Auf diesem Trägermaterial ist ein Plastikelement angeordnet und mit dem Trägerelement verklebt, wobei das Plastikelement zusammen mit dem Trägerelement eine Einheit bildet. Das Plastikelement hat Vorsprünge und Vertiefungen, die die aufgeraute Oberfläche definieren.In addition, the reveals US 3,712,846 a sound insulation element, which consists of a middle mineral fiber plate and two outside of this mineral fiber plate disposed mineral fiber elements, wherein the mineral fiber elements have a relation to the middle mineral fiber plate increased density. On the two mineral fiber elements a cover layer is additionally arranged, which has a roughened surface. The cover layer consists of a support element in the form of a fabric, which is formed from a suitable material and impregnated with a suitable elastomer. A plastic element is arranged on this carrier material and adhesively bonded to the carrier element, wherein the plastic element forms a unit together with the carrier element. The plastic element has protrusions and depressions that define the roughened surface.

Weiterhin offenbart die DE 42 22 207 A1 ein Verfahren zum Herstellen von Mineralfaserprodukten mit verdichteten Oberflächenbereichen aus Mineralfaserbahnen, die einen Faserverlauf im Wesentlichen parallel oder rechtwinklig oder schräg zu den großen Oberflächen aufweisen und ein unausgehärtetes Bindemittel enthalten. Mindestens ein Oberflächenbereich wird Nadelstößen bis zu einer vorgegebenen Eindringtiefe ausgesetzt, so dass die Fasern verfilzen und gleichzeitig der Oberflächenbereich verdichtet wird. Auf diese Weise wird eine einteilige Dämmschicht ausgebildet, die in den Oberflächenbereichen durch ein Verfilzen der Mineralfasern eine erhöhte Rohdichte gegenüber dem mittleren Bereich aufweist.Furthermore, the disclosure DE 42 22 207 A1 a process for producing mineral fiber products having densified surface areas of mineral fiber webs having a grain of fibers substantially parallel or perpendicular or oblique to the large surfaces and containing an uncured binder. At least one surface area is exposed to needle punctures to a predetermined penetration depth to entangle the fibers and at the same time compact the surface area. In this way, a one-piece insulating layer is formed, which has an increased apparent density in the surface regions due to entanglement of the mineral fibers compared to the middle region.

Ferner ist aus der EP 2 277 500 A2 ein Verfahren zur Herstellung einer Dämmstoffbahn bekannt, bei dem eine Primärvliesbahn in Teilbahnen unterteilt wird und zumindest eine Teilbahn komprimiert und anschließend mit zumindest einer weiteren Teilbahn wieder zusammengeführt wird, die gemeinsam zu einer monolithischen Sekundärvliesbahn verbunden werden.Furthermore, from the EP 2 277 500 A2 a method for producing an insulating material web is known in which a primary nonwoven web is divided into partial webs and compressed at least one sub-web and then merged with at least one further sub-web, which are connected together to form a monolithic secondary nonwoven web.

Es ist die Aufgabe der vorliegenden Erfindung, eine Mineralfaser-Dämmschicht derart weiterzubilden, dass deren Herstellung, insbesondere Montage wesentlich vereinfacht und beschleunigt ist, so dass eine kostengünstige Montage bei gleichzeitig zumindest gleichguten Dämmergebnissen möglich ist.It is the object of the present invention to develop a mineral fiber insulating layer in such a way that their production, in particular assembly essential is simplified and accelerated, so that a cost-effective installation at the same time at least as good Dämmergebnissen is possible.

Als Lösung wird mit der Erfindung eine gattungsgemäße Mineralfaser-Dämmschicht aus Dämmplatten vorgeschlagen, bei der der Mineralfaserkörper aus drei getrennt voneinander ausgebildeten und einbaubaren sandwichartig angeordneten Schichten aus Mineralfasern besteht, von denen die mittlere Schicht eine geringere Rohdichte und/oder dynamische Steifigkeit als die beiden äußeren Schichten hat und wobei zumindest die mittlere Schicht einen laminaren Faserverlauf aufweist, das heißt, dass die Mineralfasern im Wesentlichen parallel zu den großen Oberflächen des Mineralfaserkörpers ausgerichtet sind.As a solution , the invention proposes a generic mineral fiber insulating layer of insulating boards, in which the mineral fiber body consists of three separately formed and installed sandwich-like layers of mineral fibers, of which the middle layer has a lower bulk density and / or dynamic stiffness than the two outer Has layers and wherein at least the middle layer has a laminar fiber profile, that is, that the mineral fibers are aligned substantially parallel to the large surfaces of the mineral fiber body.

Die erfindungsgemäße Dämmschicht besteht somit aus zumindest drei Schichten, die flächig übereinander angeordnet sind, wobei die Schichten eine unterschiedliche Rohdichte und/oder dynamische Steifigkeit aufweisen. Vorzugsweise ist vorgesehen, dass der Mineralfaserkörper aus drei Schichten besteht, von denen die mittlere Schicht eine geringere Rohdichte und/oder dynamische Steifigkeit hat, als die beiden äußeren Schichten. Der Mineralfaserkörper und somit die Dämmschicht weist somit im Bereich der mittleren Schicht eine hohe Kompressibilität und Biegbarkeit auf, während die beiden äußeren Schichten eine demgegenüber höhere Steifigkeit haben, die somit bei einem bestimmten Übermaß der Dämmschicht vollflächig und fest an einer Verkleidung einer Gebäudewand anliegen. Die Dämmschichtdicke zwischen den Verkleidungselementen wird somit ausschließlich über die kompressible mittlere Schicht auf den Abstand zwischen den beiden benachbarten Verkleidungen eingestellt.The insulating layer according to the invention thus consists of at least three layers, which are arranged one above the other flatly, wherein the layers have a different bulk density and / or dynamic rigidity. It is preferably provided that the mineral fiber body consists of three layers, of which the middle layer has a lower bulk density and / or dynamic stiffness, than the two outer layers. The mineral fiber body and thus the insulating layer thus has in the middle layer a high compressibility and flexibility, while the two outer layers have a contrast higher stiffness, which thus rest at a certain excess of the insulating layer over the entire surface and fixed to a panel of a building wall. The insulating layer thickness between the cladding elements is thus adjusted exclusively via the compressible middle layer to the distance between the two adjacent cladding.

Vorzugsweise besteht der Mineralfaserkörper aus mehreren, mit ihren Schmalseiten aneinander liegenden Dämmplatten, die beispielsweise nacheinander zwischen Profilen von Ständerwände eingebaut werden. Hierbei können die Dämmplatten eine Materialstärke aufweisen, die im Wesentlichen mit dem Abstand der Verkleidungen übereinstimmt. Ist der Abstand der Verkleidungen jedoch größer als die Materialstärke der Dämmplatten bzw. der Dämmschicht, so können zwei oder mehr Dämmplatten oder andere Dämmelemente zur Bildung der Dämmschicht nebeneinander liegend eingebaut werden.Preferably, the mineral fiber body consists of several, with their narrow sides adjacent insulation boards, which are installed, for example, successively between profiles of stud walls. Here, the insulation boards may have a material thickness that substantially coincides with the distance of the panels. However, if the distance between the cladding is greater than the material thickness of the insulating boards or the insulating layer, two or more insulating boards or other insulating elements can be installed side by side to form the insulating layer.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die beiden äußeren Schichten unterschiedliche Rohdichten und/oder Materialstärken aufweisen. DieseAccording to a further feature of the invention, it is provided that the two outer layers have different densities and / or material thicknesses. These

Ausgestaltung ermöglicht eine weitere Anpassung der Dämmschicht an die anwendungsspezifisch erforderlichen Eigenschaften.Design allows further adaptation of the insulating layer to the application-specific properties required.

Es ist ferner vorgesehen, dass die Schichten in Teilbereichen elastifiziert ausgebildet sind, um eine richtungsabhängige Steifigkeit der Dämmschicht bzw. der die Dämmschicht bildenden Dämmelemente einzustellen. Die Teilbereiche sind insbesondere in Längs- und/oder Querrichtung der Schichten verlaufend ausgebildet. Ergänzend kann vorgesehen sein, dass sich die Teilbereiche über die gesamte Materialstärke der Schichten erstrecken.It is further provided that the layers are made elasticized in partial areas in order to set a direction-dependent stiffness of the insulating layer or the insulating layer forming the insulating elements. The subregions are designed to extend in particular in the longitudinal and / or transverse direction of the layers. In addition, it can be provided that the subregions extend over the entire material thickness of the layers.

Vorzugsweise sind die Teilbereiche streifenförmig ausgebildet und erstrecken sich nach einem weiteren vorteilhaften Merkmal über die gesamte Breite und/oder Länge der Schichten.Preferably, the subregions are strip-shaped and, according to a further advantageous feature, extend over the entire width and / or length of the layers.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass zumindest eine Schicht in einer Oberfläche mehrere Ausnehmungen aufweiset, die mit zähhartem bis sprödem Material, insbesondere mit Mörtel, vorzugsweise Klebemörtel ausgefüllt sind. Durch diese Ausgestaltung wird die Querzugsfestigkeit entsprechender Dämmschichten variiert.According to a further feature of the invention, it is provided that at least one layer in a surface has a plurality of recesses which are filled with tough to brittle material, in particular with mortar, preferably adhesive mortar. This configuration varies the transverse tensile strength of corresponding insulating layers.

Vorzugsweise sind die Ausnehmungen rund ausgebildet und können nach einem weiteren Merkmal der Erfindung in einem regelmäßigen Raster oder reihenweise versetzt angeordnet sein.Preferably, the recesses are round and can be arranged offset according to a further feature of the invention in a regular grid or in rows.

Es hat sich ferner als vorteilhaft erwiesen, die Schichten vorzugsweise durch ihre Mineralfaserausrichtung mit in Längsrichtung und Querrichtung unterschiedlichen Festigkeitseigenschaften, insbesondere Biegezugfestigkeiten und Steifigkeiten auszubilden. Beispielsweise können die Schichten derart angeordnet sein, dass sie entsprechend ihren Festigkeitseigenschaften gleichgerichtet oder rechtwinklig zueinander ausgerichtet sind. Hierdurch können gezielt die Eigenschaften der Dämmschicht auf den entsprechenden Anwendungsfall angepasst werden.It has also proven to be advantageous to form the layers preferably by their mineral fiber orientation with different in the longitudinal direction and transverse strength properties, in particular bending tensile strengths and stiffnesses. For example, the layers may be arranged such that they are rectified or oriented at right angles to each other according to their strength properties. As a result, the properties of the insulating layer can be specifically adapted to the corresponding application.

Es hat sich als vorteilhaft erwiesen, die beiden äußeren Schichten aus Steinwolle und die mittlere Schicht aus Glaswolle auszubilden, um ein geeignetes Dämmelement auszubilden, mit dem ein Dickenausgleich optimal möglich ist.It has proven to be advantageous to form the two outer layers of rock wool and the middle layer of glass wool in order to form a suitable insulating element with which a thickness compensation is optimally possible.

Zumindest die mittlere Schicht weist einen laminaren Faserverlauf auf, um eine hohe Kompressibilität in Richtung der Flächennormalen der großen Oberflächen des Dämmelementes zu ermöglichen.At least the middle layer has a laminar fiber profile in order to enable high compressibility in the direction of the surface normal of the large surfaces of the insulating element.

Wie bereits erwähnt ist es vorteilhaft, die Gesamtdicke der Schichten größer auszubilden als den Abstand der beiden parallelen Schenkel des Profils, zwischen denen die Dämmschicht einzubringen ist. Die äußeren Schichten liegen bei einer solchen Ausgestaltung fest an den Verkleidungselementen an. Hieraus resultiert eine Verminderung der Schwingungsfähigkeit der Dämmschicht, so dass die Schalldämmung einer hiermit ausgebildeten Gebäudewand wesentlich verbessert, d.h. erhöht ist.As already mentioned, it is advantageous to make the total thickness of the layers greater than the distance between the two parallel legs of the profile, between which the insulating layer is to be introduced. The outer layers are in such an embodiment firmly on the cladding elements. This results in a reduction of the vibration capability of the insulating layer, so that the sound insulation of a building wall formed therewith substantially improved, i. is increased.

Unterschiedliche dynamische Steifigkeiten in verschiedenen Zonen einer Dämmschicht lassen sich durch eine künstliche Elastifizierung von Platten mit zunächst homogener Struktur erreichen. Zu diesem Zweck wird eine der großen Oberflächen in vorteilhafter Weise mehrfach mit Walzen kleinen Durchmessers überrollt, was zu hohen linearen, insbesondere aber Scherbeanspruchungen in der Oberfläche führt. Die Struktur der Dämmplatte wird dadurch bis zu der gewünschten Tiefe zerwalkt, so dass die dynamische Steifigkeit deutlich reduziert wird.Different dynamic stiffnesses in different zones of an insulating layer can be achieved by an artificial elastification of plates with initially homogeneous structure. For this purpose, one of the large surfaces is advantageously rolled over several times with rolls of small diameter, which leads to high linear, but in particular shear stresses in the surface. As a result, the structure of the insulating board is unwrapped to the desired depth, so that the dynamic rigidity is significantly reduced.

Dämmplatten aus Mineralfasern weisen in der Regel über ihre großen Oberflächen weitgehend gleichmäßige, wenn auch richtungsabhängig unterschiedlich hohe Festigkeitseigenschaften auf. Insbesondere bei derartigen Dämmelementen aus Steinwolle sind diese richtungsabhängigen Unterschiede der Festigkeitseigenschaften zu beobachten. Dämmelemente aus Steinwolle werden in an sich bekannter Weise dadurch hergestellt, dass die aus einer silikatischen Schmelze gewonnenen Mineralfasern zunächst in Form eines dünnen Vlieses, einem sogenannten Primärvlies gesammelt und anschließend einer pendelnden Fördereinrichtung zugeführt werden. Das Primärvlies wird mit pendelnden Bewegungen dieser Fördereinrichtung auf einem Bandförderer abgelegt und auf diesem zu einer endlosen Mineralfaserbahn zusammengeschoben. Eine hierbei vorgenommene Längskompression der abgelegten Faserbahn, die auch als Sekundärvlies bezeichnet wird, führt zu einer unterschiedlichen Anordnung der Mineralfasern quer zur Förderrichtung und in Längsrichtung des Sekundärvlieses. Quer zur Förderrichtung ist die Biegezugfestigkeit und die Steifigkeit des Sekundärvlieses deutlich höher als in Längsrichtung, d.h. in Förderrichtung. Hieraus ergeben sich auch richtungsabhängige schalltechnische Eigenschaften der hieraus hergestellten Mineralfaserdämmelemente.As a rule, insulating boards made of mineral fibers have largely uniform, if dependent on the direction, different strength properties over their large surfaces. In particular, in such insulation elements made of rock wool, these directional differences in the strength properties are observed. Rock wool insulation elements are produced in a manner known per se by collecting the mineral fibers obtained from a silicate melt first in the form of a thin fleece, a so-called primary fleece, and then feeding them to a swinging conveying device. The primary fleece is deposited with oscillating movements of this conveyor on a belt conveyor and pushed together on this to an endless mineral fiber web. A longitudinal compression of the deposited fibrous web, which is also referred to as a secondary nonwoven, results in a different arrangement of the mineral fibers transversely to the conveying direction and in the longitudinal direction of the secondary nonwoven. Transverse to the conveying direction, the bending tensile strength and the stiffness of the secondary web is significantly higher than in the longitudinal direction, ie in the conveying direction. This also results in directional acoustic properties of the mineral fiber insulation elements produced therefrom.

Die Steifigkeit der Mineralfaserdämmelemente wird durch eine Lockerung der Bindung der einzelnen Fasern untereinander verändert. Beispielsweise kann durch einen Walkvorgang örtlich hoher Druck auf die Mineralfasern ausgeübt werden, wodurch die Verbindung zwischen einzelnen Mineralfasern gelockert und die Mineralfasern selbst gebrochen oder umgelagert werden. Das Resultat dieser Vorgehensweise ist eine Elastifizierung der Mineralfaserbahn. Hieraus hergestellte Mineralfaserdämmelemente werden durch diese Vorgehensweise kompressibler bzw. leichter biegbar gemacht.The rigidity of Mineralfaserdämmelemente is changed by relaxing the binding of the individual fibers with each other. For example, locally high pressure can be exerted on the mineral fibers by a waving process, whereby the connection between individual mineral fibers is loosened and the mineral fibers themselves are broken or rearranged. The result of this procedure is an elastification of the mineral fiber web. Mineral fiber insulation elements made from this are made more compressible or easier to bend by this procedure.

Hiermit einhergehend ist aber auch eine Veränderung der schalltechnischen Eigenschaften dieser Mineralfaserdämmelemente, die in Wandkonstruktionen einbaubar sind. Der Vorteil dieser Mineralfaserdämmstoffe liegt aber nunmehr darin, dass durch die örtlich unterschiedlichen dynamischen Steifigkeiten bzw. unterschiedlichen Schalldämpfungseigenschaften anwendungsfallspezifische Dämmschichten herstellbar sind. Hierbei erfolgt die Elastifizierung insbesondere quer zu der Richtung der größten Steifigkeit der Mineralfaserdämmelemente.Along with this, however, there is also a change in the acoustic properties of these Mineralfaserdämmelemente that can be installed in wall constructions. However, the advantage of these mineral fiber insulating materials lies in the fact that application-specific insulating layers can be produced by the locally different dynamic stiffnesses or different sound damping properties. In this case, the elastification takes place in particular transversely to the direction of the greatest rigidity of Mineralfaserdämmelemente.

Bei zweischichtigen Dämmschichten, die außen eine höhere und innen eine geringere Rohdichte aufweisen, können die Dämmelemente durch eine entsprechende Formgebung der aneinander grenzenden Oberflächen rein mechanisch zusammengefügt sein.In the case of two-layer insulating layers, which have a higher density on the outside and a lower density on the inside, the insulating elements can be joined together purely mechanically by appropriate shaping of the adjoining surfaces.

Die einzelnen Schichten der Dämmschicht werden getrennt voneinander eingebaut.The individual layers of the insulating layer are installed separately.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die mittlere Schicht eine im Vergleich zu den äußeren Schichten größere Länge aufweist und insbesondere im Bereich einer, vorzugsweise beider Schmalseiten(n) in Längsrichtung über die äußeren Schichten hervorsteht. Eine derart ausgebildete Dämmschicht hat den Vorteil, dass beim Einbau der Dämmschicht zwischen die Schenkel des Profils der von der mittleren Schicht hervorstehende Bereich innerhalb des Raumes zwischen den Schenkels des Profils komprimiert wird und diesen Raum folglich ausfüllt, so dass ein dichtes Anliegen der weniger kompressiblen äußeren Schichten vollflächig an dem Profil möglich ist.According to a further feature of the invention, it is provided that the middle layer has a greater length compared to the outer layers and protrudes in the longitudinal direction over the outer layers in particular in the region of one, preferably both narrow sides (n). Such a formed insulating layer has the advantage that when installing the insulating layer between the legs of the profile of the protruding from the middle layer area is compressed within the space between the leg of the profile and thus fills this space, so that a dense concern the less compressible outer Layers over the entire surface of the profile is possible.

Hierzu hat es sich als vorteilhaft erwiesen, wenn die mittlere Schicht eine in Längsrichtung und/oder zumindest eine rechtwinklig dazu verlaufende Ausnehmung aufweist, so dass die mittlere Schicht beispielsweise in zwei Abschnitte geteilt ist, die sich beim Kompression in entgegengesetzte Richtungen bewegen lassen, um den Raum zwischen den Schenkeln des Profils vollständig auszufüllen. Vorzugsweise ist die Ausnehmung im Querschnitt T-förmig ausgebildet, so dass sie eine Art Sacklochöffnung bildet und ein Abscheren der beiden Abschnitte der mittleren Schicht bei der Kompression innerhalb des Profils vermieden wird. Die Überstände der mittleren Schicht sind vorzugsweise unterschiedlich ausgebildet, um zum einen eine Markierung anzugeben, mit welcher Schmalseite die Dämmschicht innerhalb des Profils anzuordnen ist und welche Schmalseite an der außenliegenden Fläche des Stegs des gegenüberliegenden Profils anliegt und zum anderen den unterschiedlichen Bedingungen gerecht zu werden, die zwischen den Schenkeln und bei der Anlage an der Außenfläche des Stegs bestehen. Alternativ zu einem Überstand der mittleren Schicht kann vorgesehen sein, dass die Bereiche an den Längs- und/oder Schmalseiten des Mineralfaserkörpers insbesondere durch Stauchen elastifiziert sind. Durch diese Elastifizierung wird die Kompressibilität der äußeren Schichten derart erhöht, dass ein Eindrücken der Dämmschicht zwischen die Schenkel des Profils wesentlich vereinfacht ist und gleichzeitig die Dämmschicht mit Übermaß im Vergleich zum Abstand benachbarter Profile ausgebildet und klemmend eingebaut werden kann.For this purpose, it has proved to be advantageous if the middle layer has a longitudinally extending and / or at least a perpendicular thereto recess, so that the middle layer is divided, for example, into two sections which can be moved in compression in opposite directions to the Space between completely fill the legs of the profile. Preferably, the recess is T-shaped in cross section, so that it forms a kind of blind hole opening and shearing of the two sections of the middle layer is avoided during the compression within the profile. The supernatants of the middle layer are preferably formed differently in order to indicate a mark with which narrow side the insulating layer is to be arranged within the profile and which narrow side rests against the outer surface of the web of the opposite profile and on the other to meet the different conditions, which exist between the legs and at the plant on the outer surface of the web. As an alternative to a projection of the middle layer, provision may be made for the regions on the longitudinal and / or narrow sides of the mineral fiber body to be elasticized, in particular by upsetting. By this elastification, the compressibility of the outer layers is increased so that a depression of the insulating layer between the legs of the profile is substantially simplified and at the same time the insulating layer formed with excess compared to the distance between adjacent profiles and can be installed by clamping.

Vorzugsweise weisen die äußeren Schichten eine Rohdichte von 200 bis 600 kg/m3 auf. Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die äußeren Schichten eine Schichtdicke von 3 bis 20 mm haben.The outer layers preferably have a bulk density of 200 to 600 kg / m 3 . According to a further feature of the invention, it is provided that the outer layers have a layer thickness of 3 to 20 mm.

Hinsichtlich einer gattungsgemäßen Gebäudewand wird mit der Erfindung die Ausbildung der Dämmschicht nach einem der Ansprüche 1 bis 22 vorgeschlagen.With regard to a generic building wall, the invention proposes the formation of the insulating layer according to one of claims 1 to 22.

Sämtliche voranstehend diskutierten Merkmale der erfindungsgemäßen Dämmschicht können bei einer erfindungsgemäßen Gebäudewand vorgesehen sein und bilden diese erfindungsgemäß weiter.All of the above-discussed features of the insulating layer according to the invention can be provided in a building wall according to the invention and form these further according to the invention.

Eine in Figur 1 dargestellte Gebäudewand 1 besteht aus zumindest mehreren nebeneinander lotrecht aufgestellten Profilen 2, von denen in Figur 1 zwei benachbart angeordnete Profile 2 dargestellt sind. Zwischen den Profilen 2 ist eine Dämmschicht 3 angeordnet, die nachfolgend näher beschrieben wird.An in FIG. 1 illustrated building wall 1 consists of at least several side by side vertically erected profiles 2, of which in FIG. 1 two adjacently arranged profiles 2 are shown. Between the profiles 2 an insulating layer 3 is arranged, which will be described in more detail below.

Jedes Profil 2 ist im Querschnitt C-förmig ausgebildet und hat zwei parallel zueinander verlaufende Schenkel 4 und einen die Schenkel 4 verbindenden, zu den Schenkeln 4 rechtwinklig ausgerichteten Steg 5, der in seinem Mittelbereich eine Sicke 6 zur Aussteifung hat. An den freien Enden der Schenkel 4 sind Abbiegungen 7 angeordnet, die aufeinanderzu ausgerichtet sind. Der Raum zwischen den Schenkeln 4 einerseits und den Abbiegungen 7 sowie dem Steg 5 andererseits ist mit einem Profilkörper 8 aus Dämmmaterial, nämlich Mineralfasern ausgefüllt.Each profile 2 is C-shaped in cross-section and has two mutually parallel legs 4 and a leg 4 connecting, perpendicular to the legs 4 aligned web 5, which has a bead 6 in its central region for stiffening. At the free ends of the legs 4 bends 7 are arranged, which are aligned with each other. The space between the legs 4 on the one hand and the bends 7 and the web 5 on the other hand is filled with a profile body 8 of insulating material, namely mineral fibers.

Es ist zu erkennen, dass die beiden in Figur 1 dargestellten Profile 2 in gleicher Orientierung ausgerichtet sind, so dass die Dämmschicht 3 einerseits an dem Profilkörper 8 im Bereich der Abbiegungen 7 und andererseits, d.h. im Bereich des zweiten Profils 2 an der Außenfläche des Stegs 5 anschließt. Die Dämmschicht 3 ist zwischen der Außenseite des Stegs 5 und dem Profilkörper 8 des benachbarten Profils 2 klemmend gehalten.It can be seen that the two in FIG. 1 Profiles 2 are aligned in the same orientation, so that the insulating layer 3 on the one hand to the profile body 8 in the region of the bends 7 and on the other hand, ie in the region of the second profile 2 on the outer surface of the web 5 connects. The insulating layer 3 is clamped between the outside of the web 5 and the profile body 8 of the adjacent profile 2.

Die Gebäudewand 1 weist ferner zwei Verkleidungen 9 auf, von denen in Figur 1 lediglich eine Verkleidung 9 dargestellt ist, welche mit nicht näher dargestellten Schrauben mit den Schenkeln 4 benachbarter Profile 2 verbunden ist, wobei die Verkleidung 9 aus mehreren Verkleidungselementen, beispielsweise Gipskartonplatten besteht.The building wall 1 also has two panels 9, of which in FIG. 1 only a panel 9 is shown, which is connected by screws not shown with the legs 4 adjacent profiles 2, wherein the panel 9 consists of several cladding elements, such as plasterboard.

Die Dämmschicht 3 besteht aus einem Mineralfaserkörper 10, der in mehrere Dämmplatten unterteilt ist, die übereinander zwischen benachbarten Profilen 2 angeordnet sind.The insulating layer 3 consists of a mineral fiber body 10, which is divided into a plurality of insulating boards, which are arranged one above the other between adjacent profiles 2.

Der Mineralfaserkörper weist drei Schichten 11 und 12 auf, wobei die beiden äußeren Schichten 11 aus Steinwolle und die mittlere Schicht 12 aus Glaswolle besteht.The mineral fiber body has three layers 11 and 12, wherein the two outer layers 11 made of rock wool and the middle layer 12 consists of glass wool.

Die mittlere Schicht 12 hat im Vergleich zu den beiden äußeren Schichten 11 eine geringere Rohdichte und eine geringere dynamische Steifigkeit, so dass sie insgesamt kompressibel ausgebildet ist, wobei ihre Kompressibilität sowohl in Richtung der Flächennormalen der großen Oberflächen 13 der Dämmschicht 3 als auch rechtwinklig hierzu vorgesehen ist. Der Mineralfaserkörper 10 ist im Übrigen in der Figur 2 im Längsschnitt im uneingebauten Zustand dargestellt. Die mittlere Schicht 12 hat einen laminaren Faserverlauf, d.h., die Mineralfasern der mittleren Schicht 12 sind im Wesentlichen parallel zu den großen Oberflächen 13 des Mineralfaserkörpers 10 ausgerichtet. Je nach Anwendungsgebiet können die Mineralfasern der äußeren Schichten 11 ebenfalls parallel zu den großen Oberflächen 13 oder rechtwinklig zu den großen Oberflächen 13 ausgerichtet sein. In Abhängigkeit des Faserverlaufs in den äußeren Schichten 11 werden die Festigkeitseigenschaften des Mineralfaserkörpers 10 wesentlich mitbestimmt.The middle layer 12 has compared to the two outer layers 11 has a lower bulk density and a lower dynamic stiffness, so that it is designed to be compressible overall, with their compressibility provided both in the direction of the surface normal of the large surfaces 13 of the insulating layer 3 and at right angles thereto is. The mineral fiber body 10 is otherwise in the FIG. 2 shown in longitudinal section in the uninstalled state. The middle layer 12 has a laminar fiber profile, ie, the mineral fibers of the middle layer 12 are aligned substantially parallel to the large surfaces 13 of the mineral fiber body 10. Depending on the field of application, the mineral fibers of the outer layers 11 may also be aligned parallel to the large surfaces 13 or at right angles to the large surfaces 13. Depending on the fiber flow in the outer layers 11, the strength properties of the mineral fiber body 10 are substantially determined.

Aus Figur 2 ist zu erkennen, dass die mittlere Schicht 12 über die Längsseiten 14 der äußeren Schichten 11 hervorsteht, wobei die mittlere Schicht 12 im Bereich einer Längsseite 14 weiter hervorsteht, als im Bereich der gegenüberliegenden Längsseite 14 der äußeren Schichten 11. Diese Ausgestaltung hat den Vorteil, dass beispielsweise der Raum im Bereich der Sicke 6 bzw. der Raum eines verdrängten Profilkörpers 8 durch die kompressible mittlere Schicht 12 ausgefüllt wird, so dass keine Hohlräume verbleiben, die gegebenenfalls die Wärme- und/oder Schalldämmeigenschaften der Dämmschicht 3 nachteilig beeinflussen.Out FIG. 2 It can be seen that the middle layer 12 projects beyond the longitudinal sides 14 of the outer layers 11, the middle layer 12 projecting further in the region of one longitudinal side 14 than in the region of the opposite longitudinal side 14 of the outer layers 11. This embodiment has the advantage that that, for example, the space in the region of the bead 6 or the space of a displaced profile body 8 is filled by the compressible middle layer 12, so that no cavities remain, which may adversely affect the heat and / or sound insulation properties of the insulation layer 3.

In Figur 3 ist eine weitere Ausführungsform eines Mineralfaserkörpers 10 dargestellt, der ergänzend zu dem Ausführungsbeispiel gemäß Figur 2 auf beiden großen Oberflächen 13 der äußeren Schichten 11 eine Kaschierung 15 aus einem mit zumindest einem organischen und anorganischen Bindemittel gebundenen und ausgehärtetem Fasermehl aufweist.In FIG. 3 a further embodiment of a mineral fiber body 10 is shown, which in addition to the embodiment according to FIG. 2 on both large surfaces 13 of the outer layers 11 has a lamination 15 of a bound and cured with at least one organic and inorganic binder fiber flour.

Die Kaschierung 15 hat eine Rohdichte von 300 kg/m3 und eine Schichtdicke von 10 mm.The lamination 15 has a bulk density of 300 kg / m 3 and a layer thickness of 10 mm.

Die mittlere Schicht 12 des Ausführungsbeispiels gemäß Figur 3 weist in ihrem über die Längsseite 14 hervorstehenden Abschnitt 16 einen in Längsrichtung der mittleren Schicht 12, sich über die gesamte Länge des Mineralfaserkörpers 10 erstreckende Ausnehmung 17 auf, die im Querschnitt T-förmig ausgebildet ist. Der Mineralfaserkörper 10 wird mit dem Abschnitt 16 in ein Profil 2 zwischen die Schenkel 4 anstelle des Profilkörpers 8 eingesteckt, so dass sich die kompressible mittlere Schicht 12 in ihrer Formgebung derart ändert, dass der Abschnitt 16 den Raum zwischen den Schenkeln 4 zumindest annähernd vollständig ausfüllt. Zu diesem Zweck ist die Ausnehmung 17 vorgesehen, die eine mittige Teilung des Abschnitts 17 ermöglicht, so dass die beiden durch die Ausnehmung 17 ausgebildeten Hälften des Abschnitts 16 sich beidseitig der Ausnehmung 17 verformen. Die T-förmige Ausgestaltung der Ausnehmung 17 verhindert hierbei einen Bruch des Abschnitts 16, wobei die beidseitig des quer verlaufenden Endes der Ausnehmung 17 angeordneten Faserbereiche die Funktion eines Gelenkes übernehmen und das Wegklappen der beiden Hälften des Abschnitts 16 erlauben.The middle layer 12 of the embodiment according to FIG. 3 has in its projecting beyond the longitudinal side portion 16 a in the longitudinal direction of the middle layer 12, extending over the entire length of the mineral fiber body 10 recess 17, which is T-shaped in cross section. The mineral fiber body 10 is inserted with the section 16 in a profile 2 between the legs 4 instead of the profile body 8, so that the compressible middle layer 12 changes in shape such that the portion 16 at least approximately completely fills the space between the legs 4 , For this purpose, the recess 17 is provided, which allows a central division of the portion 17, so that the two formed by the recess 17 halves of the portion 16 deform on both sides of the recess 17. The T-shaped configuration of the recess 17 in this case prevents a fraction of the portion 16, wherein the both sides of the transverse end of the recess 17 arranged fiber regions assume the function of a joint and allow the folding away of the two halves of the section 16.

Die Figuren 4 bis 6 zeigen eine äußere Schicht 11 in Form einer Dämmplatte. Die Schicht 11 weist im Bereich ihrer Oberflächen 13 elastifizierte Teilbereiche 20 auf. In diesen Teilbereichen ist die Oberfläche 13 der Schicht 11 durch einen Walkvorgang mechanisch belastet, so dass die einzelnen Mineralfasern in ihrer Bindung zueinander aufgelöst und teilweise gebrochen sind. Die Schicht 11 gemäß den Figuren 4 bis 5 weist diesbezüglich einen Teilbereich 20 auf, der sich parallel zur Längserstreckung der Schicht 11 über die gesamte Länge der Schicht 11 erstreckt und in der Mittelachsenebene der Schicht 11 angeordnet ist.The FIGS. 4 to 6 show an outer layer 11 in the form of an insulating board. The layer 11 has in the region of its surfaces 13 elasticized portions 20. In these subregions, the surface 13 of the layer 11 is mechanically stressed by a milling process, so that the individual mineral fibers are dissolved in their bond to each other and partially broken. The layer 11 according to the FIGS. 4 to 5 has in this regard a portion 20 which extends parallel to the longitudinal extent of the layer 11 over the entire length of the layer 11 and is arranged in the center axis plane of the layer 11.

Rechtwinklig zu diesem Teilbereich 20 hat die Schicht 11 drei quer zur Längserstreckung verlaufende Teilbereiche 20, von denen der mittlere Teilbereich im Mittelbereich der Schicht 11 und die beiden äußeren Teilbereiche in gleichmäßigem Abstand zum mittleren Teilbereich 20 angeordnet sind.Perpendicular to this portion 20, the layer 11 has three transverse to the longitudinal extent extending portions 20, of which the central portion in the central region of the layer 11 and the two outer portions are arranged at a uniform distance from the central portion 20.

Die elastifizierten Teilbereiche 20 erstrecken sich gemäß den Figuren 5 und 6 über die gesamte Materialstärke der Schicht 11 und dienen der Erhöhung der Kompressibilität der Schicht 11 in Richtung der Teilbereiche.The elasticized portions 20 extend according to the FIGS. 5 and 6 over the entire material thickness of the layer 11 and serve to increase the compressibility of the layer 11 in the direction of the subregions.

Durch ihre Herstellungsweise weist die Schicht 11 in Richtung des Schnittes gemäß Figur 5 eine hohe Längssteifigkeit und in Richtung des Schnittes gemäß Figur 6 eine geringe Längssteifigkeit auf, so dass entsprechend der Anzahl der elastifizierten Teilbereiche 20 eine gleichmäßige Kompressibilität der Schicht 11 gegeben ist.By their method of preparation, the layer 11 in the direction of the section according to FIG. 5 a high longitudinal stiffness and in the direction of the cut according to FIG. 6 a low longitudinal stiffness, so that according to the number of elasticized portions 20 a uniform compressibility of the layer 11 is given.
