Die vorliegende Erfindung betrifft ein Schalungsmodul zur Herstellung von betonsparenden Wänden gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a formwork module for the production of concrete-saving walls according to the preamble of patent claim 1.

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 Herstellungskosten solcher Wände erheblich.Factors that drive home construction are, in particular, the large quantities of building materials used, and 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 produce concrete in view of the static requirements, correspondingly large amounts of concrete must be consumed. As a result, the cost of such walls increase significantly.

Die WO 97/43507 A1 beschäftigt sich mit einem Schalungsmodul zur Herstellung betonsparender Wände an Fertigteilen gemäß dem Oberbegriff des Patentanspruches 1. Das Schalungsmodul weist ein Basiselement auf, welches eine Stützfunktion erfüllt. Mehrere nebeneinander angeordnete Formkörper bilden ein Fußelement für eine Schalungswand, die in das Fußelement eingesetzt wird. Die Schalungswand wird gebildet von Paneelen, die nur eine vergleichsweise geringe Höhe aufweisen. Zur Ausbildung von Ecken sind separate Elemente vorgesehen. Ein ähnliches Schalungsmodul mit separaten Eckelementen ist auch aus der US 6,324,812 B1 bekannt.The WO 97/43507 A1 deals with a formwork module for the production of concrete-saving walls of prefabricated parts according to the preamble of claim 1. The formwork module has a base member which fulfills a support function. Several juxtaposed moldings form a foot element for a formwork wall, which is inserted into the foot element. The formwork wall is formed by panels which have only a comparatively small height. For the formation of corners separate elements are provided. A similar formwork module with separate corner elements is also from the US 6,324,812 B1 known.

Des Weiteren ist es bekannt zur Herstellung herkömmlicher Wände aus Beton ebene Schalungswandelemente mit Ankern zu verbinden, wobei auch hier zur Ausbildung von Ecken spezielle Eckelemente vorgesehen sind. Ein solches Schalungsmodul ist in der EP 0 123 264 A2 beschrieben.Furthermore, it is known for the production of conventional walls made of concrete flat shuttering wall elements to connect with anchors, with special corner elements are also provided here for the formation of corners. Such a formwork module is in the EP 0 123 264 A2 described.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Schalungsmodul zur Herstellung von betonsparenden Wänden anzugeben, welches auf einfache Weise die Bildung von Ecken ermöglicht.Against this background, the invention has for its object to provide a formwork module for the production of concrete-saving walls, which allows the formation of corners in a simple manner.

Gegenstand der Erfindung und Lösung der Aufgabe ist ein Schalungsmodul gemäß Patentanspruch 1.The object of the invention and solution of the problem is a formwork module according to claim 1.

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. Das heißt, 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.For the purposes of the present invention, portions derived from the shape of a trapezoid are typically those portions which have a baseline and, starting from these two side lines, such that a trapezoid is formed with an imaginary second baseline opposite the baseline. However, the second baseline is not part of the sections. The two side lines form with the baseline an obtuse angle α preferably in a range of 120 ° to 150 °, wherein preferably the angle α between the baseline and the one side line and the baseline and the other side line is identical. That is, with an imaginary complete trapezoid formed by adding the imaginary further baseline, the baseline associated with the section is made shorter than the baseline just opposite it. However, the sections can also be designed in such a way that, starting from a baseline, a lateral line is arranged at an obtuse angle .alpha., Which accordingly returns to a baseline. These sections can also be described as trapezoidal sections, which are bisected at the level of the center of the baseline and assembled after rotation of a section by 180 ° and reflection of the other section to each other. For the formation of corners sections can be used, which have starting from a baseline with this an obtuse angle α forming side line, and this section with a corresponding trained and mirror-inverted arranged second section is connected.

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 vorgesehene Stützmittel auf beiden Seiten des durch die Schalungswände 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, beispielsweise 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, gebildet 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 arranged at such a distance from one another that a kind of zigzag-like band is formed by them, but interrupted in each case by linear regions formed by the respective baselines. These linear areas formed by the baselines serve as a bearing surface for preferably provided support means on both sides of the formwork system formed by the formwork walls. After filling of concrete in the interior of this formwork system and removal of the formwork walls, optionally after an equally successful removal of the support means, the linear areas serve as support surfaces for applied to the wall produced lightweight panels or other cladding, such as clinker. The support means for holding and fixing the two formwork walls to each other may be formed in particular from plates and / or pipe or rod and / or frame systems, as these are known from formwork modules used in construction, wherein the support means are preferably fixedly connected to the shuttering walls , The formwork module according to the invention typically consists of units formed by the two formwork walls and the support means fixedly connected thereto, 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 beispielsweise 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.By means of the formwork module according to the invention, it is advantageously possible to produce statically stable walls with a considerably reduced amount of concrete. For example, in the production of a 24 cm wide wall with a formwork module for a 24 cm wide wall, only about 0.085 m 3 of concrete / m 2 of wall is needed. At least is preferred an amount of about 0.06 m 3 , more preferred is a range of 0.065 m 3 to 0.095 m 3 concrete / m 2 .

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 das Schalungsmodul dazu vorgesehen, stabile Wand-Eckelemente herzustellen, wobei ein rechter Winkel vorgesehen ist und wobei die von beiden Seiten auf die Ecke zulaufenden Abschnitte gleich ausgebildet und miteinander verbunden sind.By juxtaposing a plurality of alternating first and second sections can be made arbitrarily flexible and in length as well as in height different walls. Thus, the formwork module according to the invention offers a variety of combination and thus of applications. Also, the formwork module is intended to produce stable wall corner elements, wherein a right angle is provided and wherein the tapered from both sides of the corner sections are formed equal and interconnected.

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.Advantageously, at least one reinforcing element is arranged between the shuttering walls. This reinforcing element is preferably provided centrally between the two formwork walls. Particularly preferred as a reinforcing element a bendable mat is provided, but it can also be used other curved reinforcing elements. The reinforcing elements are held in particular by construction iron in position.

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 mindestens 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 shuttering walls formed by the respective baselines of the sections are connected to the shuttering walls by at least one armature, preferably at least two armatures, wherein the armature is arranged approximately at the level of the center of the baseline. An armature arranged in this way firmly connects the support means arranged on the two outer sides with the two formwork walls. It is removed after incorporation and hardening of the concrete.

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 einfachst 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 ein Langloch auf seinen beiden den jeweiligen Abschnitten zugewandten Seiten aufweist. 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 Verbindung kann jedoch nicht nur durch ein System AusnehmungNorsprung gebildet werden, auch jedes weitere denkbare Verbindungssystem ist möglich, beispielsweise eine Verbindung über ineinandergreifende vorstehende Haken, Anker, vorgesehene Rastungen etc..The sections are advantageously formed from a plurality of interconnected, in particular screwed, and hookable components. Between these components, in order to achieve the highest possible flexibility of the formwork system according to the invention, even the lateral and / or baselines of the imaginary trapezoid can be arranged to extend the planar center elements. As a result, for example, it is extremely easy to produce a 30 cm thick wall from a 24 cm thick wall using the same components. This is especially true if the planar central elements have elongate recesses / bores through which a projection arranged, for example, on the section can engage in a sliding manner. Then there is the possibility of a widening of the wall, wherein advantageously such a plane middle element has two equally arranged elongated recesses or a slot on its two sides facing the respective sections. Such a planar central element may be provided with at least two such elongated recesses, in which engage the projections of the sections, to achieve a secure and accurate construction of the formwork walls, respectively arranged on the two sides facing the sections of the planar central element. Of course, however, any other type of connection of the central elements may be provided with the sections. The recesses / holes may be formed, for example, round or square. Preferably, a secure connection between the sections and the middle elements is achieved by a screw, in which case advantageously in example the slot engaging projection is provided with a thread, so that after use of the central element that can be connected by a nut fixed to the section. Of course, it is also possible that at least one projection in the middle elements is provided for the recesses / holes in the sections, and vice versa. However, a secure connection can not only be achieved through a System be formed recess projection, any other conceivable connection system is possible, for example, a connection via interlocking projecting hooks, anchors, provided notches 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 shuttering wall can also be integrally formed. Preferably, the formwork wall and thus also the sections or the planar middle elements made of aluminum and / or galvanized sheet metal, for cost reasons, preferably made of galvanized sheet metal.

Die mit dem Schalungsmodul hergestellte 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.The wall made with the formwork module will meet the requirements placed on them in house construction and is also considerably cheaper to produce in terms of only a very small amount of concrete used compared to conventional solid concrete walls. Preference is given to concrete, especially waterproof concrete B35, are used.

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 aufgebracht werden. Für eine Hallenkonstruktion z.B. kann beispielsweise die Wand auch unverklinkert belassen werden.Preferably, the wall according to the invention is provided on at least one side with at least one lightweight panel. The lightweight panels come to rest on the defined by the baseline of the trapezoidal sections of the formwork modules wall areas and can be attached to these by means of drilling or the like. The thereby resulting between the lightweight panels and the zigzag-like running concrete wall cavities can be filled with insulating or other material. The wall can be provided on both sides not only with identical lightweight panels, but also with different lightweight panels, which allows maximum flexibility. On external walls, for example, a Verklinkerung be applied. For example, for a hall construction, the wall can also be left unclicked.

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 zueinander gehalten. Die Anker verlaufen dabei auf Höhe der Mitte der Grundlinien 6 und 7 der trapezförmigen Abschnitte 3 und 4. Fig. 1 shows a total of one designated by the reference numeral 1 formwork module in a wall-corner combination for producing, for example, a 24 cm thick wall. The formwork module 1 has two shuttering walls 2 and 5, wherein the shuttering walls 2 and 5 are each formed of sections 3 and 4. The sections 3 and 4 are arranged alternately and mirror-inverted to each other to a continuous wall 2 and 5 respectively. The sections 3 and 4 consist in the plan view of baselines 6 and 7 with side lines 15 and 16, wherein the angle α is approximately 140 °. The formwork walls 2 and 5 and thus the sections 3 and 4 may have any height, depending on the requirements of the wall to be produced. By means of anchors 13, the formwork walls 2 and 5 are held with formed from tubes support means 10 and 11 on the two defined by the respective baselines 6 and 7 of the sections 3 and 4 outer sides 9 to each other. The anchors extend at the level of the center of the baselines 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, das heißt 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 verlänger, so dass zusätzliche Wand-Eck-Elemente 17 und 18 gebildet werden, 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 shuttering wall 2 and the shuttering wall 5 are the same over the entire length seen, that is, the shuttering walls 2 and 5 are dimensioned identically. The corner element schematically indicates that the sides indicated by the line 19 of the formwork walls 2 tapering towards the corner from both directions are removed. At the same time, the sides of the respective formwork walls 5 tapering towards the corner are longer 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 formed from two sections 23 and 24 (in Fig. 1 each marked by a bracket), which are arranged mirror-inverted and connected to each other. The sections 23 and 24 may be aligned approximately parallel to each other, but also at an angle, and here in particular in the manner of a trapezoid to run towards each other.

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 Bewehrungselement 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 Teilabschnittes hervorgegangen beschrieben werden kann. Fig. 2 now shows in detail the arrangement of reinforcing elements 12.1 and 12.2 and 2.1 and structural iron 14 in the space formed by the shuttering walls 2 and 5. After introduction of the construction iron 14 a bendable iron mat is arranged around this around as a reinforcing element 12 approximately centrally between the two formwork walls 2 and 5. Then concrete is added to complete the wall. Alternatively to sections 3 and 4 of the Fig. 1 is a gate 22 defined, which can be described as resulting from a mental halving of the sections 3 or 4 and a subsequent rotation by 180 ° of a subsection and mirroring of the further subsection emerged.

Zur Herstellung einer erfindungsgemäßen Wand wird das aufgestellte Schalungsmodul gemäß den Fig. 1 und 2 mit Beton gefüllt und nach Aushärtung desselben die Anker 13 samt den Stützmitteln 10 und 11 entfernt. Anschließend werden ebenso die Schalungswände 2 und 5 bzw. die diese bildenden einzelnen trapezförmigen Bauteile 20 entfernt. Auf die dann freistehende zickzackartig verlaufende Wand werden von den beiden Außenseiten 8 und 9 her Leichtbauplatten angebracht, welche auf die durch die Grundlinien 6 und 7 gebildeten Auflageflächen ausreichend Halt erlangen.To produce a wall according to the invention, the erected formwork module according to Fig. 1 and 2 filled with concrete and after curing the same anchor 13 together with the support means 10 and 11 removed. Subsequently, the shuttering walls 2 and 5 or the individual trapezoidal components 20 forming these are also removed. On the then free-standing zigzag wall extending lightweight panels are mounted by the two outer sides 8 and 9, which obtain sufficient support on the bearing surfaces formed by the baselines 6 and 7.

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.When constructing a wall-corner element by means of the formwork modules according to the invention can according to Fig. 2 in the corner sections 17 and 18 by additional structural iron 14, a further reinforcing element 21 are introduced, so that the formed corner meets the static requirements. In this case, the additional reinforcing element 21 may be connected to the reinforcing elements 12.1 and 12.2, possibly via additional, not shown here elements, but can also be safely held without such a connection only by means of the construction iron 14. In this case, the reinforcing element 21 as well as the sections 23 and 24 (see Fig. 1 ) and parallel to them.
