Beschreibungdescription
Die vorliegende Erfindung betrifft ein Schalungsmodul zur Herstellung insbesondere von betonsparenden Wänden mit einer ersten und einer zweiten Schalungswand, sowie eine mittels dieses Schalungsmoduls hergestellte Wand.The present invention relates to a formwork module for producing in particular concrete-saving walls with a first and a second formwork wall, and to a wall produced by means of this formwork module.
Kostentreibende Faktoren im Hausbau sind insbesondere die großen Mengen an eingesetzten Baumaterialien, und hier insbesondere an Beton. Ist es notwendig, bzw. vorgesehen, insbesondere dicke Mauern, beispielsweise solche mit einer Breite von 24 bzw. 30 cm, im Hinblick auf die statischen Anforderungen aus Beton herzustellen, so müssen entsprechend große Mengen an Beton verbraucht werden. Hierdurch steigen die Herstel- lungskosten solcher Wände erheblich.Cost-driving factors in house construction are in particular the large quantities of building materials used, and here in particular of concrete. If it is necessary or intended, in particular thick walls, for example those with a width of 24 or 30 cm, to be made from concrete with regard to the static requirements, then correspondingly large amounts of concrete must be used. This increases the manufacturing costs of such walls considerably.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Schalungsmodul und eine Wand zur Verfügung zu stellen, welche den an diese gesetzten statischen Anforderungen genügt, gleichzeitig jedoch weniger Beton benötigt.It is therefore an object of the present invention to provide a formwork module and a wall which meets the structural requirements placed on them, but at the same time requires less concrete.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Schalungsmodul zur Herstellung insbesondere von betonsparenden Wänden mit einer ersten Schalungswand, die mindestens zwei von der Form eines Trapezes abgeleitete Abschnitte aufweist, wobei ausgehend von mindestens einem Ende des ersten Abschnittes fortlaufend der weitere, ent- sprechend ausgebildete zweite Abschnitt angeordnet ist, und mit einer zweiten Schalungswand, die im wesentlichen entsprechend der ersten Schalungswand ausgebildet ist, und wobei die Schalungswände beabstandet zueinander derart angeordnet sind, daß die Grundlinien der Abschnitte parallel zueinander angeordnet sind.This object is achieved according to the invention by a formwork module for producing, in particular, concrete-saving walls with a first formwork wall which has at least two sections derived from the shape of a trapezoid, the further, correspondingly designed second section proceeding continuously from at least one end of the first section is arranged, and with a second formwork wall, which is designed substantially corresponding to the first formwork wall, and wherein the formwork walls are arranged spaced apart from one another such that the base lines of the sections are arranged parallel to one another.
Aus der Form eines Trapezes abgeleitete Abschnitte im Sinne der vorliegenden Erfindung sind typischerweise solche Abschnitte, welche eine Grundlinie und ausgehend von dieser zwei Seitenlinien aufweisen, so daß mit einer der Grundlinie gegenüber angeordneten gedachten zweiten Grundlinie ein Trapez gebildet wird. Die zweite Grundlinie ist jedoch nicht Bestandteil der Abschnitte. Die beiden Seitenlinien bilden mit der Grundlinie einen stumpfen Winkel α bevorzugt in einem Bereich von 120° bis 150°, wobei bevorzugt der Winkel α zwischen der Grundlinie und der einen Seitenlinie sowie der Grundlinie und der anderen Seitenlinie identisch ist. D.h., daß bei einem gedachten vollständigen Trapez, welches durch Hinzufügung der gedachten weiteren Grundlinie gebildet wird, die zu dem Abschnitt gehörende Grundlinie kürzer ausgebildet ist als die dieser gegenüberliegende lediglich gedachte Grundlinie. Die Abschnitte können jedoch auch derart ausgebildet sein, daß ausgehend von einer Grundlinie eine Seitenlinie in einem stumpfen Winkel α angeordnet ist, welche entsprechend wieder in eine Grundlinie übergeht. Diese Abschnitte können auch umschrieben werden als trapezförmige Abschnitte, die auf Höhe der Mitte der Grundlinie halbiert und nach Drehung eines Teilabschnittes um 180° und Spiegelung des weiteren Teilabschnitts zueinander zusammengesetzt werden. Für die Ausbildung von Ecken können Abschnitte Verwendung finden, welche ausgehend von einer Grundlinie eine mit dieser einen stumpfen Winkel α bildende Seitenlinie aufweisen, und dieser Teilabschnitt mit einem entsprechend ausgebildeten und spiegelverkehrt angeordneten zweiten Teilabschnitt verbunden wird.Sections derived from the shape of a trapezoid in the sense of the present invention are typically those sections which have a base line and, starting from this, two side lines, so that a trapezoid is formed with an imaginary second base line arranged opposite the base line. However, the second baseline is not part of the sections. The two side lines form an obtuse angle α with the base line, preferably in a range from 120 ° to 150 °, preferably the Angle α between the baseline and one side line and the baseline and the other side line is identical. That is, in the case of an imaginary complete trapezoid, which is formed by adding the imaginary further baseline, the baseline belonging to the section is shorter than the merely imaginary baseline lying opposite it. However, the sections can also be designed in such a way that, starting from a base line, a side line is arranged at an obtuse angle α, which correspondingly merges again into a base line. These sections can also be described as trapezoidal sections, which are halved at the level of the center of the base line and which are assembled to one another after rotation of a section by 180 ° and reflection of the other section. Sections can be used for the formation of corners which, starting from a base line, have a side line forming an obtuse angle α therewith, and this section is connected to a correspondingly designed and mirror-inverted second section.
Die beiden Schalungswände sind derart zueinander beabstandet angeordnet, daß durch diese eine Art zickzackähnlich verlaufendes Band gebildet wird, unterbrochen jedoch jeweils durch lineare Bereiche, gebildet durch die jeweiligen Grundlinien. Diese linearen, durch die Grundlinien gebildeten Bereiche dienen als Auflagefläche für bevorzugt vorge- sehene Stützmittel auf beiden Seiten des durch die Schalungswände 1 und 2 gebildeten Schalungssystems. Nach Füllung von Beton in den Innenraum dieses Schalungssystems und Entfernung der Schalungswände, gegebenenfalls nach einer ebenfalls erfolgten Entfernung der Stützmittel, dienen die linearen Bereiche als Auflageflächen für auf die hergestellte Wand aufzubringenden Leichtbauplatten bzw. sonstigen Verkleidungen, beispiels- weise Klinker. Die Stützmittel zur Halterung und Fixierung der beiden Schalungswände zueinander können insbesondere gebildet sein aus Platten und/oder Rohren- bzw. Stangen- und/oder Rahmensystemen, wie diese von im Bau verwendeten Schalungsmodulen bekannt sind, wobei die Stützmittel bevorzugt fest mit den Schalungswänden verbunden sind. Das erfindungsgemäße Schalungsmodul besteht typischerweise aus Einheiten, ge- bildet durch die beiden Schalungswände und die fest mit diesen verbundenen Stützmittel, insbesondere gehalten zueinander durch mindestens einen, bevorzugt mindestens zwei, weiter bevorzugt genau zwei Anker.The two formwork walls are spaced from each other in such a way that a kind of zigzag-like band is formed by them, but interrupted in each case by linear areas formed by the respective baselines. These linear areas formed by the base lines serve as a support surface for preferably provided support means on both sides of the formwork system formed by the formwork walls 1 and 2. After concrete has been filled into the interior of this formwork system and the formwork walls have been removed, if necessary after the proppants have also been removed, the linear areas serve as support surfaces for lightweight panels or other cladding to be applied to the manufactured wall, for example clinker. The support means for holding and fixing the two formwork walls to one another can in particular be formed from plates and / or pipes or rods and / or frame systems, as are known from formwork modules used in construction, the support means preferably being firmly connected to the formwork walls , The formwork module according to the invention typically consists of units, formed by the two formwork walls and the support means firmly connected to them, in particular held to one another by at least one, preferably at least two, more preferably exactly two anchors.
Durch das erfindungsgemäße Schalungsmodul ist es vorteilhafterweise möglich, mit einer erheblich reduzierten Menge an Beton statisch stabile Wände herzustellen. So wird bei- spielsweise bei der Herstellung einer Wand mit 24 cm Breite mit einem Schalungsmodul für eine 24 cm breite Wand lediglich noch eine Menge von etwa 0,085 m3 Beton/m2 Wand benötigt. Bevorzugt ist mindestens eine Menge von etwa 0,06 m3, weiter bevorzugt ist ein Bereich von 0.065 m3 bis 0,095 m3 Beton/m2.The formwork module according to the invention advantageously makes it possible to produce statically stable walls with a considerably reduced amount of concrete. This is how for example, in the manufacture of a wall with a width of 24 cm with a formwork module for a wall with a width of 24 cm, only a quantity of about 0.085 m 3 of concrete / m 2 of wall is required. At least an amount of about 0.06 m 3 is preferred, a range from 0.065 m 3 to 0.095 m 3 concrete / m 2 is more preferred.
Durch eine Aneinanderreihung einer Vielzahl abwechselnder erster und zweiter Abschnitte können beliebig flexibel und in der Länge als auch in der Höhe unterschiedliche Wände hergestellt werden. Damit bietet das erfindungsgemäße Schalungsmodul eine Vielzahl von Kombinations- und somit von Anwendungsmöglichkeiten. Auch ist es einfach möglich, mit dem erfindungsgemäßen Schalungsmodul stabile Wand-Eckelemente herzustellen. Wird die Vorsehung beispielsweise eines rechten Winkels in einem Wand-Eckelement gewünscht, so können die von beiden Seiten auf die Ecke zulaufenden Abschnitte gleich ausgebildet sein und miteinander verbunden sein.By lining up a large number of alternating first and second sections, it is possible to produce walls that are flexible in terms of length and height. The formwork module according to the invention thus offers a large number of possible combinations and thus of possible uses. It is also easily possible to produce stable wall corner elements with the formwork module according to the invention. If, for example, the provision of a right angle in a wall corner element is desired, the sections tapering towards the corner from both sides can be of identical design and can be connected to one another.
Vorteilhafterweise ist zwischen den Schalungswänden mindestens ein Bewehrungselement angeordnet. Dieses Bewehrungselement ist bevorzugt mittig zwischen den beiden Schalungswänden vorgesehen. Besonders bevorzugt ist dabei als Bewehrungselement eine biegbare Matte vorgesehen, es können jedoch auch sonstige gebogene Bewehrungselemente eingesetzt werden. Die Bewehrungselemente sind insbesondere durch Konstruktionseisen in ihrer Position gehalten.At least one reinforcement element is advantageously arranged between the formwork walls. This reinforcement element is preferably provided centrally between the two formwork walls. A bendable mat is particularly preferably provided as the reinforcement element, but other curved reinforcement elements can also be used. The reinforcement elements are held in position by structural iron in particular.
In einer bevorzugten Ausführungsform sind die auf den beiden durch die jeweiligen Grundlinien der Abschnitte gebildeten Außenseiten der Schalungswände angeordneten Stützmittel mit den Schalungswänden durch mindestens einen Anker, bevorzugt mindes- tens zwei Anker verbunden, wobei der Anker etwa auf Höhe der Mitte der Grundlinie angeordnet ist. Ein derartig angeordneter Anker verbindet fest die auf den beiden Außenseiten angeordneten Stützmittel mit den beiden Schalungswänden. Er wird nach Einbringung und Härtung des Betons entfernt.In a preferred embodiment, the support means arranged on the two outer sides of the formwork walls formed by the respective base lines of the sections are connected to the formwork walls by at least one anchor, preferably at least two anchors, the anchor being arranged approximately at the center of the base line. An anchor arranged in this way firmly connects the support means arranged on the two outer sides to the two formwork walls. It is removed after the concrete has been poured in and hardened.
Die Abschnitte sind vorteilhafterweise gebildet aus mehreren miteinander verbindbaren, insbesondere verschraubbaren, auch verhakbaren Bauteilen. Zwischen diesen Bauteilen können zur Erreichung einer höchstmöglichen Flexibilität des erfindungsgemäßen Schalungssystems noch die Seiten- und/oder Grundlinien des gedachten Trapezes verlängernde plane Mittelelemente angeordnet werden. Hierdurch ist es beispielsweise ein- fachst möglich, aus einer 24 cm dicken Wand eine 30 cm dicke Wand unter Verwendung der gleichen Bauteile herzustellen. Dies insbesondere dann, wenn die planen Mittelelemente längliche Ausnehmungen/Bohrungen aufweisen, durch welche ein beispielsweise auf dem Abschnitt angeordneter Vorsprung gleitend eingreifen kann. Dann besteht die Möglichkeit einer Verbreiterung der Wand, wobei vorteilhafterweise ein derartiges planes Mittelelement zwei in gleicher Weise angeordnete längliche Ausnehmungen oder einThe sections are advantageously formed from a plurality of components which can be connected to one another, in particular screwed, and also hooked. In order to achieve the greatest possible flexibility of the formwork system according to the invention, planar middle elements extending the side and / or base lines of the imaginary trapezoid can be arranged between these components. This makes it possible, for example, to easily convert a 24 cm thick wall into a 30 cm thick wall to manufacture the same components. This is particularly the case when the flat central elements have elongated recesses / bores through which a projection, for example arranged on the section, can engage in a sliding manner. Then there is the possibility of widening the wall, such a flat central element advantageously having two elongate recesses or one arranged in the same way

Ein derartiges planes Mittelelement kann zur Erzielung einer sicheren und genauen Konstruktion der Schalungswände mit mindestens zwei derartigen länglichen Ausnehmungen, in welche die Vorsprünge der Abschnitte eingreifen, ausgestattet sein, angeordnet jeweils auf den beiden den Abschnitten zugewandten Seiten des planen Mittelelements. Selbstverständlich kann aber auch jede andere Art der Verbindung der Mittelelemente mit den Abschnitten vorgesehen sein. Die Ausnehmungen/ Bohrungen können beispielsweise rund oder quadratisch ausgebildet sein. Vorzugsweise wird eine sichere Verbindung zwischen den Abschnitten und den Mittelelementen durch eine Verschraubung erzielt, wobei hierbei vorteilhafterweise der in beispielsweise das Langloch eingreifende Vorsprung mit einem Gewinde versehen ist, so daß nach Einsatz des Mittelelements dieses durch eine Mutter fest mit dem Abschnitt verbunden werden kann. Selbstverständlich ist es weiterhin auch möglich, daß für die Ausnehmungen/Bohrungen in den Abschnitten, und umgekehrt, mindestens ein Vorsprung in den Mittelelementen vorgesehen ist. Eine sichere Verbin- düng kann jedoch nicht nur durch ein System Ausnehmung/Vorsprung gebildet werden, auch jedes weitere denkbare Verbindungssystem ist möglich, beispielsweise eine Verbindung über ineinandergreifende vorstehende Haken, Anker, vorgesehene Rastungen etc.Has elongated hole on its two sides facing the respective sections. Such a flat middle element can be provided with at least two such elongate recesses, in which the projections of the sections engage, arranged on the two sides of the flat middle element facing the sections, in order to achieve a safe and precise construction of the formwork walls. Of course, any other type of connection of the central elements to the sections can also be provided. The recesses / bores can be round or square, for example. Preferably, a secure connection between the sections and the central elements is achieved by means of a screw connection, in which case the projection which engages in the elongated hole, for example, is advantageously provided with a thread, so that after use of the central element, it can be firmly connected to the section by a nut. Of course, it is also possible that at least one projection is provided in the central elements for the recesses / bores in the sections and vice versa. However, a secure connection cannot only be formed by a system of recess / projection, any other conceivable connection system is also possible, for example a connection via interlocking projecting hooks, anchors, provided detents, etc.
Alternativ kann die Schalungswand auch einstückig ausgebildet sein. Vorzugsweise sind die Schalungswand und damit auch die Abschnitte, bzw. die planen Mittelelemente aus Aluminium und/oder verzinktem Blech, aus Kostengründen bevorzugt aus verzinktem Blech hergestellt.Alternatively, the formwork wall can also be formed in one piece. The formwork wall and thus also the sections or the planar central elements are preferably made of aluminum and / or galvanized sheet metal, for cost reasons preferably made of galvanized sheet metal.
Die vorliegende Erfindung betrifft weiterhin eine Wand, hergestellt mit dem erfindungsge- mäßen Schalungsmodul. Diese Wand wird den an diese im Hausbau gestellten Anforderungen gerecht und ist darüber hinaus erheblich kostengünstiger im Hinblick auf die nur ausgesprochen geringe Menge an eingesetztem Beton im Vergleich zu üblichen massiven Betonwänden herzustellen. Bevorzugt wird dabei Beton, insbesondere wasserdichter Beton B35, zum Einsatz kommen. Vorzugsweise wird die erfindungsgemäße Wand auf mindestens einer Seite mit mindestens einer Leichtbauplatte versehen. Die Leichtbauplatten kommen dabei auf den durch die Grundlinien der trapezförmigen Abschnitte des Schalungsmodules definierten Wandbereichen zum Liegen und können an diesen mittels Bohrung oder ähnlichem befestigt werden. Die sich dabei zwischen den Leichtbauplatten und der zickzackähnlich verlaufenden Betonwand ergebenden Hohlräume können mit Isolier- oder sonstigem Material verfüllt werden. Die Wand kann dabei auf beiden Seiten nicht nur mit identischen Leichtbauplatten, sondern auch mit unterschiedlichen Leichtbauplatten versehen werden, was eine maximale Flexibilität ermöglicht. Auf Außenwänden kann z. B. eine Verklinkerung aufge- bracht werden. Für eine Hallenkonstruktion z. B. kann beispielsweise die Wand auch un- verklinkert belassen werden.The present invention further relates to a wall made with the formwork module according to the invention. This wall meets the requirements placed on these in house construction and is also considerably less expensive to produce in view of the very small amount of concrete used in comparison to conventional solid concrete walls. Concrete, in particular waterproof concrete B35, is preferably used. The wall according to the invention is preferably provided on at least one side with at least one lightweight building board. The lightweight panels come to rest on the wall areas defined by the basic lines of the trapezoidal sections of the formwork module and can be attached to them by means of a hole or the like. The cavities that result between the lightweight building boards and the zigzag-like concrete wall can be filled with insulation or other material. The wall can not only be provided with identical lightweight panels on both sides, but also with different lightweight panels, which enables maximum flexibility. On outer walls, for. B. a clinker can be applied. For a hall construction z. For example, the wall can also be left unclinked.
Diese und weitere Vorteile der vorliegenden Erfindung werden anhand der folgenden Figuren erläutert. Es zeigen:These and other advantages of the present invention are explained with the aid of the following figures. Show it:
Fig. 1 eine Aufsicht auf ein erfindungsgemäßes Schalungsmodul;Figure 1 is a plan view of a formwork module according to the invention.
Fig. 2 eine weitere Aufsicht auf ein erfin- dungsgemäßes Schalungsmodul mit eingezeichneten Bewährungselementen und Konstruktionseisen;2 shows a further top view of a formwork module according to the invention with drawn-in probation elements and structural iron;
Fig. 1 zeigt insgesamt ein mit dem Bezugszeichen 1 bezeichnetes Schalungsmodul in einer Wand-Eck-Kombination zur Herstellung beispielsweise einer 24 cm dicken Wand. Das Schalungsmodul 1 weist zwei Schalungswände 2 und 5 auf, wobei die Schalungswände 2 und 5 jeweils aus Abschnitten 3 und 4 gebildet sind. Die Abschnitte 3 und 4 sind dabei abwechselnd und spiegelverkehrt zueinander zu einer fortlaufenden Wand 2 bzw. 5 angeordnet. Die Abschnitte 3 und 4 bestehen in der Aufsicht aus Grundlinien 6 bzw. 7 mit Seitenlinien 15 und 16, wobei der Winkel α in etwa 140° beträgt. Die Schalungswände 2 und 5 und damit die Abschnitte 3 und 4 können eine beliebige Höhe aufweisen, je nach den Erfordernissen der herzustellenden Wand. Mittels Ankern 13 sind die Schalungswände 2 und 5 mit aus Rohren gebildeten Stützmitteln 10 und 11 auf den beiden durch die jeweiligen Grundlinien 6 und 7 der Abschnitte 3 und 4 definierten Außenseiten 9 zueinan- der gehalten. Die Anker verlaufen dabei auf Höhe der Mitte der Grundlinien 6 und 7 der trapezförmigen Abschnitte 3 und 4.1 shows a formwork module, designated by the reference number 1, in a wall-corner combination for producing, for example, a 24 cm thick wall. The formwork module 1 has two formwork walls 2 and 5, the formwork walls 2 and 5 each being formed from sections 3 and 4. Sections 3 and 4 are arranged alternately and mirror-inverted to one another to form a continuous wall 2 and 5, respectively. Sections 3 and 4 consist of top lines 6 and 7 with side lines 15 and 16, the angle α being approximately 140 °. The formwork walls 2 and 5 and thus the sections 3 and 4 can have any height, depending on the requirements of the wall to be manufactured. By means of anchors 13, the formwork walls 2 and 5 are joined together with support means 10 and 11 formed from tubes on the two outer sides 9 defined by the respective base lines 6 and 7 of the sections 3 and 4. who held. The anchors run at the level of the center of the base lines 6 and 7 of the trapezoidal sections 3 and 4.
Die Abstände zwischen der Schalungswand 2 und der Schalungswand 5 sind über die gesamte Länge gesehen gleich, d. h. die Schalungswände 2 und 5 sind identisch bemaßt. Im Eckelement ist schematisch angedeutet, daß die durch die Linie 19 angedeuteten Seiten der aus beiden Richtungen auf die Ecke zulaufenden Schalungswände 2 entfernt sind. Gleichzeitig sind die auf die Ecke zulaufenden Seiten der jeweiligen Schalungswände 5 zur Ecke hin verlängert, so daß zusätzliche Wand-Eck-Elemente 17 und 18 gebildet wer- den, wenn das Schalungsmodul mit Beton, vorzugsweise B35, gefüllt wird. Das Eckelement kann auch beschrieben werden als gebildet aus zwei Teilabschnitten 23 und 24 (in Fig. 1 jeweils durch eine Klammer gekennzeichnet), die zueinander spiegelverkehrt angeordnet und verbunden sind. Die Teilabschnitte 23 und 24 können dabei in etwa parallel zueinander ausgerichtet sein, aber auch winklig, und hier insbesondere nach Art eines Trapezes aufeinander zu verlaufen.The distances between the formwork wall 2 and the formwork wall 5 are the same over the entire length, i. H. the formwork walls 2 and 5 are dimensioned identically. In the corner element it is indicated schematically that the sides indicated by the line 19 of the formwork walls 2 running towards the corner from both directions have been removed. At the same time, the sides of the respective formwork walls 5 tapering to the corner are extended towards the corner, so that additional wall corner elements 17 and 18 are formed when the formwork module is filled with concrete, preferably B35. The corner element can also be described as being formed from two sections 23 and 24 (each identified by a bracket in FIG. 1), which are arranged and connected in a mirror-inverted manner to one another. The sections 23 and 24 can be aligned approximately parallel to one another, but also at an angle, and here, in particular, run in the manner of a trapezoid.
Fig. 2 zeigt nun im Detail die Anordnung von Bewehrungselementen 12.1 und 12.2 sowie 2.1 und Konstruktionseisen 14 in dem durch die Schalungswände 2 und 5 gebildeten Raum. Nach Einbringung der Konstruktionseisen 14 wird um diese herum als Beweh- rungselement 12 eine biegbare Eisenmatte in etwa mittig zwischen den beiden Schalungswänden 2 und 5 angeordnet. Anschließend wird Beton zur Fertigstellung der Wand zugegeben. Alternativ zu den Abschnitten 3 und 4 der Fig. 1 ist ein Anschnitt 22 definiert, der als aus einer gedanklichen Halbierung der Abschnitte 3 oder 4 und einer nachfolgenden Drehung um 180° eines Teilabschnittes sowie Spiegelung des weiteren Teilabschnit- tes hervorgegangen beschrieben werden kann.2 now shows in detail the arrangement of reinforcement elements 12.1 and 12.2 and 2.1 and structural iron 14 in the space formed by the formwork walls 2 and 5. After the construction iron 14 has been introduced, a bendable iron mat is arranged around it as a reinforcing element 12 approximately in the middle between the two formwork walls 2 and 5. Then concrete is added to complete the wall. As an alternative to sections 3 and 4 of FIG. 1, a section 22 is defined, which can be described as being the result of a conceptual halving of sections 3 or 4 and a subsequent rotation through 180 ° of a section as well as reflection of the further section.
Zur Herstellung einer erfindungsgemäßen Wand wird das aufgestellte Schalungsmodul gemäß den Fig. 1 bis 3 mit Beton gefüllt und nach Aushärtung desselben die Anker 13 samt den Stützmitteln 10 und 11 entfernt. Anschließend werden ebenso die Schalungs- wände 2 und 5 bzw. die diese bildenden einzelnen trapezförmigen Bauteile 20 entfernt. Auf die dann freistehende zickzackartig verlaufende Wand werden von den beiden Aus- senseiten 8 und 9 her Leichtbauplatten angebracht, welche auf die durch die Grundlinien 6 und 7 gebildeten Auflageflächen ausreichend Halt erlangen. Bei Konstruktion eines Wand-Eck-Elementes mittels des erfindungsgemäßen Schalungsmodules kann gemäß Fig. 2 in die Eckabschnitte 17 und 18 durch zusätzliche Konstruktionseisen 14 ein weiteres Bewehrungselement 21 eingebracht werden, so daß auch die gebildete Ecke den statischen Anforderungen genügt. Dabei kann das zusätzliche Bewehrungselement 21 mit den Bewehrungselementen 12.1 und 12.2 verbunden sein, ggf. über zusätzliche, hier nicht gezeigte Elemente, kann jedoch auch ohne eine solche Verbindung lediglich mittels der Konstruktionseisen 14 sicher gehalten werden. Dabei kann das Bewehrungselement 21 ebenso wie die Teilabschnitte 23 und 24 (siehe Fig. 1) ausgerichtet sein, und parallel zu diesen verlaufen. To produce a wall according to the invention, the erected formwork module according to FIGS. 1 to 3 is filled with concrete and, after it has hardened, the anchors 13 together with the support means 10 and 11 are removed. Then the formwork walls 2 and 5 or the individual trapezoidal components 20 forming them are also removed. On the then free-standing zigzag wall, lightweight panels are attached from the two outer sides 8 and 9, which have sufficient support on the support surfaces formed by the base lines 6 and 7. When constructing a wall corner element by means of the formwork module according to the invention, a further reinforcement element 21 can be introduced into the corner sections 17 and 18 by means of additional structural iron 14, as shown in FIG. 2, so that the corner formed also meets the structural requirements. The additional reinforcement element 21 can be connected to the reinforcement elements 12.1 and 12.2, possibly via additional elements not shown here, but can also be held securely by means of the construction iron 14 even without such a connection. The reinforcement element 21, like the sections 23 and 24 (see FIG. 1), can be aligned and run parallel to them.
