Description

Die Erfindung bezieht sich auf ein Schalungsteil der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a formwork part explained in the preamble of claim 1 Art.

Schalungen für den Betonbau müssen einem nicht unbeträchtlichen Betondruck standhalten. Es ist deshalb üblich, Schalungen und Schalungsmaterialien mit einer Versteifung zu versehen, was insbesondere dann zweckmäßig oder notwendig ist, wenn relativ dünnwandige Schalungsmaterialien, wie Bleche oder Tafeln in den unterschiedlichsten Formen, Gittermatten oder Streckmetall eingesetzt werden. Die Versteifung geschieht oft durch so genannte Gitterträger, das sind vorgefertigte Strukturen aus einer Mehrzahl von Streben, die in bestimmter Weise zusammengesetzt und miteinander verbunden werden. So existieren beispielsweise flächige Gitterträger, bei denen zwei Längsstäbe oder Längsgurte parallel zueinander angeordnet und in dieser Lage durch Diagonalstreben miteinander verbunden sind. Diese Gitterträger werden dann mit einem ihrer Längsstäbe mit dem Schalungsmaterial der Schaltafel so verbunden, dass sie mit ihrer Hauptebene im Wesentlichen senkrecht zur Ebene der Schaltafel verlaufen. Ein Schalungsmaterial, das auf diese Weise verstärkt ist, ist beispielsweise aus der DE 100 37 193 bekannt. Das bekannte Schalungsmaterial ist jedoch zusätzlich auf der dem Gitterträger gegenüberliegenden Seite mit Querstäben versteift, wodurch das Schalungsmaterial schwer und aufwändig in der Herstellung ist.Formwork for concrete construction must withstand a not inconsiderable concrete pressure. It is therefore customary to provide formwork and formwork materials with a stiffening, which is particularly useful or necessary when relatively thin-walled formwork materials, such as sheets or panels are used in a variety of forms, mesh mats or expanded metal. The stiffening is often done by so-called lattice girders, which are prefabricated structures of a plurality of struts, which are assembled in a certain way and interconnected. For example, there are flat lattice girders in which two longitudinal bars or longitudinal straps are arranged parallel to each other and connected together in this position by diagonal struts. These lattice girders are then connected with one of their longitudinal bars with the formwork material of the formwork panel so that they extend with their main plane substantially perpendicular to the plane of the formwork panel. A formwork material which is reinforced in this way, for example, from DE 100 37 193 known. However, the known formwork material is additionally stiffened on the opposite side of the lattice girder with transverse bars, whereby the formwork material is difficult and expensive to manufacture.

Der Erfindung liegt die Aufgabe zugrunde, ein Schalungsteil bereitzustellen, das leicht und einfach herstellbar, sowie vielseitig einsetzbar ist.The invention has for its object to provide a formwork part that is easy and easy to manufacture, and versatile.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße Ausgestaltung wird ein Schalungsteil bereitgestellt, das durch Verwendung einer Versteifungseinrichtung mit in zwei Ebenen liegenden Diagonalstreben auf einfache Weise sowohl quer als auch längs versteift ist, wodurch es leicht und einfach in der Herstellung ist. Es kann so wie es ist, direkt als Schalung eingesetzt werden, da es eine ausreichende Versteifung in beiden Richtungen aufweist. Zum anderen ist das erfindungsgemäße Schalungsteil so geformt und ausgebildet, dass sich damit eine Vielzahl von Schalungen auf einfache Weise, auch auf der Baustelle, herstellen lassen.The embodiment according to the invention provides a formwork part which is stiffened both transversely and longitudinally in a simple manner by using a stiffening device with diagonal struts lying in two planes, whereby it is easy and simple to manufacture. It can be used directly as formwork as it is because it has sufficient stiffening in both directions. On the other hand, the inventive Molded part shaped and designed so that it can be a variety of formwork in a simple manner, even on the construction site, produce.

Die Herstellung wird weiter vereinfacht, wenn als Versteifungseinrichtung einer der bekannten Gitterträger eingesetzt wird, wobei bevorzugt ein flächiger Gitterträger verwendet wird, der im Bereich seiner Diagonalstreben im wesentlichen rechtwinklig abgebogen wurde.The production is further simplified if one of the known lattice girders is used as stiffening device, wherein preferably a flat lattice girder is used, which was bent at right angles in the region of its diagonal struts.

Die universelle Verwendbarkeit des Schalungsteils wird entscheidend verbessert, wenn die Ebene der zur Schaltafel senkrechten Bereiche der Versteifungseinrichtung entlang einer Kante der Schaltafel verläuft.The universal applicability of the formwork part is decisively improved when the plane of the panel perpendicular to the formwork portions of the stiffener extends along an edge of the formwork panel.

Die Versteifungswirkung der Versteifungseinrichtung kann durch verschiedene Maßnahmen verbessert werden, so beispielsweise indem die Diagonalstreben an ihren von der Schaltafel wegweisenden Enden miteinander verbunden sind, oder indem sich die zur Ebene der Schaltafel parallelen Bereiche der Versteifungseinrichtung von einer Kante der Schaltafel zur gegenüberliegenden Kante erstrecken, oder indem die Diagonalstreben je nach Einsatzzweck besonders ausgestaltet sind, oder indem die Diagonalstreben am parallel zur Ebene der Schaltafel abgewinkelten Bereich der Versteifungseinrichtung durch wenigstens einen Längsstab verbunden sind, der direkt oder indirekt mit der Schaltafel verbunden ist.The stiffening effect of the stiffening device can be improved by various measures, such as by the diagonal struts are connected to each other at their facing away from the formwork panel ends, or by extending parallel to the plane of the form panel portions of the stiffening device from one edge of the formwork panel to the opposite edge, or in that the diagonal struts are specially designed according to the intended use, or in that the diagonal struts are connected to the region of the stiffening device which is angled parallel to the plane of the formwork panel by at least one longitudinal bar which is connected directly or indirectly to the formwork panel.

Als Schalungsmaterial wird bevorzugt ein durchbrochenes Schalungsmaterial eingesetzt, das eine Verwendung des Schalungsteils als verlorene Schalung gestattet.As a formwork material preferably a perforated formwork material is used, which allows use of the formwork part as a lost formwork.

Das erfindungsgemäße Schalungsteil wird bevorzugt hergestellt, indem herkömmliche und handelsübliche Gitterträger verwendet und in entsprechend gebogenem Zustand an der Schaltafel befestigt werden.The formwork part according to the invention is preferably produced by using conventional and commercially available lattice girders and attached to the formwork panel in a correspondingly bent state.

Das erfindungsgemäße Schalungsteil kann paarweise zur Herstellung von Fugenschalungen mit Halterungen für elastische Fugenbänder oder mit eingeschweißtem Fugenblech verwendet werden, kann jedoch auch so wie es ist, als Randabschalung oder als Fugenabschalung ohne Fugenband für Sohlen oder Decken eingesetzt werden.The formwork part according to the invention can be used in pairs for the production of joint formwork with brackets for elastic joint tapes or with welded joint plate, but can also be used as Randabschalung or as joint formwork without joint tape for soles or ceilings as it is.

Das Schalungsteil 1 enthält eine Schaltafel 2 aus einem vergleichsweise dünnwandigen Material. Als Material für die Schaltafel 2 eignet sich jedes zum Abschalen eingesetzte Material, bevorzugt besteht die Schaltafel 2 jedoch aus einem durchbrochenen Material, wie beispielsweise einem Streckmetallblech, einem Lochblech, einer Gittermatte, oder anderen durchbrochenen Materialien, wodurch das Schalungsteil 1 besonders an die Verwendung als verlorene Schalung angepasst ist. Im dargestellten Ausführungsbeispiel hat die Schaltafel 2 die Form eines lang gestreckten Rechtecks aus Steckmetall, das in Fig. 4, der besseren Übersichtlichkeit halber nur bereichsweise angedeutet ist.From the Fig. 1 to 5 is a first embodiment of a formwork part 1 according to the invention can be seen. The formwork part 1 contains a formwork panel 2 made of a comparatively thin-walled material.

In the illustrated embodiment, the formwork panel 2 has the shape of an elongated rectangle of plug metal, in Fig. 4 , which is indicated for reasons of clarity only in certain areas.

Die Schaltafel 2 ist mit einer Versteifungseinrichtung 3 versehen. Die Versteifungseinrichtung 3 enthält einen ersten Bereich 3a, der sich in einer ersten Ebene parallel zur Ebene der Schaltafel 2 erstreckt und mit der Schaltafel 2 fest, insbesondere durch Schweißen, verbunden ist. Der parallele Bereich 3a erstreckt sich bevorzugt über im Wesentlichen eine gesamte Breite b der Schaltafel 2, von einer Kante zur gegenüberliegenden Kante.The formwork panel 2 is provided with a stiffening device 3. The stiffening device 3 includes a first region 3a, which extends in a first plane parallel to the plane of the formwork panel 2 and is fixedly connected to the formwork panel 2, in particular by welding. The parallel region 3a preferably extends over substantially an entire width b of the formwork panel 2, from one edge to the opposite edge.

Die Versteifungseinrichtung 3 enthält weiterhin einen zweiten Bereich 3b, der sich an den ersten Bereich 3a direkt anschließt und mit diesem verbunden ist. Der zweite Bereich 3b erstreckt sich in einer zweiten Ebene, die im Wesentlichen senkrecht zur Schaltafel 2 verläuft. Der Begriff "im Wesentlichen" soll hier einen gewollten Winkel von 90° zur Schaltafel 2 beschreiben, jedoch auch Winkelabweichungen mit einschließen, die sich beispielsweise durch unbeabsichtigte Verformungen oder Herstellungsungenauigkeiten ergeben, die geplante Funktion des Schalungsteils 1 jedoch nicht stören oder gar verhindern. Die Ebene, in der sich der senkrechte Bereich 3b der Versteifungseinrichtung 3 befindet, verläuft entlang einer Kante der Schaltafel 2, wobei sich der parallele Bereich 3a von dieser Kante zur gegenüberliegenden Kante erstreckt.The stiffening device 3 further includes a second region 3b, which directly adjoins the first region 3a and is connected thereto. The second region 3b extends in a second plane, which runs essentially perpendicular to the switching board 2. The term "essentially" is intended here to describe a desired angle of 90 ° to the formwork panel 2, but also include angle deviations that result, for example, by unintentional deformations or manufacturing inaccuracies, but do not disturb the planned function of the formwork part 1 or even prevent. The plane in which the vertical portion 3b of the stiffener 3 is located extends along an edge of the formwork panel 2, the parallel portion 3a extending from this edge to the opposite edge.

Sowohl der parallele Bereich 3a als auch der senkrechte Bereich 3b enthalten Diagonalstreben 4. Als Diagonalstreben werden Streben definiert, die mit ihren jeweiligen Abschnitten innerhalb der ersten oder zweiten Ebene liegen, jedoch zur jeweils anderen Ebene einen von 90° verschiedenen Winkel einschließen, d.h. dass die Diagonalstrebe 4 im parallelen Bereich 3a schräg zur Ebene des senkrechten Bereichs 3b, und die Diagonalstrebe 4 im senkrechten Bereich 3b schräg zur Ebene des parallelen Bereichs 3averläuft. Es sind zwei Gruppen von Diagonalstäben 4 vorgesehen, wobei die eine Gruppe in eine Richtung schräg verläuft, d.h. einen spitzen Winkel zur benachbarten Ebene einschließt, und die Diagonalstäben der anderen Gruppe in die andere Richtung geneigt sind. Bevorzugt sind die Diagonalstäbe der Gruppen abwechselnd angeordnet, so dass entlang der Längserstreckung der Schaltafel 2 jeweils auf einen oder mehrere Diagonalstäbe, die in eine Richtung geneigt sind, ein oder mehrere Diagonalstäbe folgen, die in die Gegenrichtung geneigt sind.Both the parallel region 3a and the vertical region 3b contain diagonal struts 4. As diagonal struts, struts are defined which lie with their respective sections within the first or second plane, but one to the other plane of 90 °, ie that the diagonal strut 4 in the parallel region 3a obliquely to the plane of the vertical region 3b, and the diagonal strut 4 in the vertical region 3b obliquely to the plane of the parallel region 3a runs. Two groups of diagonal bars 4 are provided, one group being inclined in one direction, ie enclosing an acute angle to the adjacent plane, and the diagonal bars of the other group being inclined in the other direction. Preferably, the diagonal bars of the groups are arranged alternately, so that along the longitudinal extension of the formwork panel 2 in each case follow one or more diagonal bars which are inclined in one direction, one or more diagonal bars which are inclined in the opposite direction.

Die Neigung der Diagonalstäbe 4 und ihre Anordnung in den Ebenen der parallelen und senkrechten Bereiche 3a, 3b erfolgt bevorzugt regelmäßig und symmetrisch.The inclination of the diagonal bars 4 and their arrangement in the planes of the parallel and vertical areas 3a, 3b preferably takes place regularly and symmetrically.

Die Diagonalstäbe, insbesondere im senkrechten Bereich 3b sind über ihre außen, d. h. im Abstand über der Schaltafel 2, liegenden Enden miteinander verbunden. Dies erfolgt bevorzugt durch einen Längsgurt (Obergurt) oder Längsstab 5, der an allen äußeren Enden befestigt ist. Darüber hinaus können die Diagonalstäbe 4 auch im parallelen Bereich 3a mit ihren nach außen weisenden Enden miteinander verbunden sein, was ebenfalls durch einen Längsgurt (Untergurt) oder Längsstab 6 geschieht, an dem die nach außen weisenden Enden der Diagonalstäbe 4 befestigt sind.The diagonal bars, in particular in the vertical area 3b are above their outside, d. H. at a distance above the formwork panel 2, lying ends connected together. This is preferably done by a longitudinal belt (top flange) or longitudinal bar 5, which is attached to all outer ends. In addition, the diagonal bars 4 can also be connected to each other in the parallel region 3a with their outwardly facing ends, which also takes place by a longitudinal belt (bottom flange) or longitudinal bar 6, to which the outwardly pointing ends of the diagonal bars 4 are fastened.

Wird für die Schaltafel 2 ein verletzungsträchtiges Material eingesetzt, beispielsweise ein scharfkantiges Blech oder ein Streckmetall, so können zumindest die parallelen Längskanten 2a und 2b schützend nach innen gebogen werden, was bevorzugt um den Längsstab 6 bzw. um den Übergang zwischen dem parallelen Bereich 3a und dem senkrechten Bereich 3b geschieht. Diese übergefalteten Randbereiche 2a, 2b sind nicht in allen Figuren gezeichnet, können jedoch in allen Ausführungsformen vorgesehen sein.If an injury-resistant material is used for the formwork panel 2, for example a sharp-edged metal sheet or an expanded metal, then at least the parallel longitudinal edges 2a and 2b can be bent inwards in a protective manner, preferably around the longitudinal bar 6 or around the transition between the parallel areas 3a and 3b the vertical area 3b happens. These folded-over edge regions 2a, 2b are not drawn in all figures, but may be provided in all embodiments.

Die Diagonalstreben 4 im parallelen Bereich 3a und im senkrechten Bereich 3b sind zumindest teilweise miteinander verbunden und sind bevorzugt Teil eines gemeinsamen Gitterträgers 7, wie er in Fig. 5 näher dargestellt ist. Beim Gitterträger 7 liegen die Diagonalstreben 4 in Form einer Mehrzahl V-förmiger Diagonalstrebenpaare 4a vor, die jeweils identisch ausgebildet sind und in vorbestimmten Abständen und in gleicher Ausrichtung miteinander verbunden sind. Im dargestellten Ausführungsbeispiel bedeutet dies, dass die freien Enden der V-förmigen Diagonalstrebenpaare 4a mit einem der Längsstäbe, d.h. dem Längsstab 5 des senkrechten Bereichs, und die Scheitel oder Richtungsumkehrbereiche der V-förmigen Diagonalstrebenpaare 4a mit dem anderen Längsstab, d.h. dem Längsstab 6 des parallelen Bereichs miteinander verbunden sind. Die Diagonalstrebenpaare können jedoch auch umgekehrt angeordnet sein, d.h. mit ihren freien Enden am Längsstab 6 des parallelen Bereichs 3a befestigt sein.The diagonal struts 4 in the parallel region 3a and in the vertical region 3b are at least partially connected to each other and are preferably part of a common lattice girder 7, as in Fig. 5 is shown in more detail. When lattice girder 7, the diagonal struts 4 are in the form of a plurality of V-shaped diagonal strut pairs 4a, which are each formed identically and connected to each other at predetermined intervals and in the same orientation are. In the illustrated embodiment, this means that the free ends of the V-shaped diagonal strut pairs 4a with one of the longitudinal bars, ie the longitudinal bar 5 of the vertical area, and the apex or direction reversal areas of the V-shaped diagonal strut pairs 4a with the other longitudinal bar, ie the longitudinal bar 6 of parallel area are interconnected. However, the diagonal strut pairs can also be arranged in reverse, ie be fastened with their free ends to the longitudinal bar 6 of the parallel area 3a.

Das Schalungsteil 1 gemäß den Fig. 1 bis 5 wird hergestellt, indem zunächst ein flächiger Gitterträger 7 gefertigt bzw. bereitgestellt wird. Der Gitterträger 7 besteht bevorzugt aus Stabmaterial aus Bewehrungsstahl, wie er zur Bewehrung und zum Aufbau von Schalungen auch bisher schon eingesetzt wurde. Das Material ist schweißbar, so dass die Diagonalstrebenpaare 4a mit den Längsstäben 5, 6 verschweißt werden können. Dann wird ein Schaltafel 2, im dargestellten Ausführungsbeispiel in Form eines lang gestreckten Streifens, bereitgestellt, wobei die Breite b des Streifens der Schaltafel 2 etwa der halben Breite des Gitterträgers 7 zwischen den Längsstäben 5, 6 entspricht (zzgl. eventueller Überstände für die umgebogenen Randkanten 2a, 2b). Dann werden die Diagonalstreben 4 des Gitterträgers 7 entlang der strichpunktiert dargestellten Biegelinie 8 etwa in der Mitte zwischen den Längsstäben 5, 6 in einen Winkel von im Wesentlichen 90° gebogen, so dass aus dem Gitterträger 7 die Versteifungseinrichtung 3 mit den im Winkel von 90° zueinander stehenden Bereichen 3a, und 3b der Diagonalstreben 4 wird. Diese Versteifungseinrichtung 3 wird dann mit der Schaltafel 2 vereinigt, wobei die Befestigung der Versteifungseinrichtung 3 an der Schaltafel 2 bei einem schweißbaren Material für die Schaltafel 2 bevorzugt ebenfalls durch Schweißen erfolgt. Dabei wird der parallele Bereich 3a direkt mit der Schaltafel 2 oder indirekt, beispielsweise über den Längsstab 6, einen gesonderten Schweißstab oder dgl. so verbunden, dass der senkrechte Bereich 3b entlang einer Kante der Schaltafel 2 verläuft und sich der parallele Bereich 3a im Wesentlichen bis zur gegenüberliegenden Kante der Schaltafel 2 erstreckt. Anschließend werden gegebenenfalls die Randbereiche 2a, 2b nach oben/innen in eine verletzungsgeschützte Position gebogen.The formwork part 1 according to the Fig. 1 to 5 is made by first producing or providing a flat lattice girder 7. The lattice girder 7 is preferably made of rod material made of reinforcing steel, as he has also been used for reinforcement and to build formworks. The material is weldable, so that the diagonal strut pairs 4a can be welded to the longitudinal bars 5, 6. Then, a formwork panel 2, in the illustrated embodiment in the form of an elongated strip, provided, wherein the width b of the strip of the formwork panel 2 about half the width of the lattice girder 7 between the longitudinal bars 5, 6 corresponds (plus any protrusions for the bent marginal edges 2a, 2b). Then the diagonal struts 4 of the lattice girder 7 are bent along the dash-dotted bend line 8 approximately in the middle between the longitudinal bars 5, 6 at an angle of substantially 90 °, so that from the lattice girder 7, the stiffening device 3 with the angle of 90 ° mutually standing areas 3a, and 3b of the diagonal struts 4 is. This stiffening device 3 is then combined with the formwork panel 2, wherein the attachment of the stiffening device 3 to the formwork panel 2 in a weldable material for the formwork panel 2 preferably also takes place by welding. In this case, the parallel region 3a is directly connected to the formwork panel 2 or indirectly, for example via the longitudinal bar 6, a separate welding rod or the like., That the vertical portion 3b along one edge of the formwork panel 2 extends and the parallel portion 3a substantially until extends to the opposite edge of the formwork panel 2. Subsequently, if appropriate, the edge regions 2a, 2b are bent upwards / inwards into an injury-protected position.

Es ist nicht erforderlich, die Diagonalstreben 4 in ihrer Mitte zwischen den Stäben 5, 6 abzuwinkeln. Je nach gewünschter Versteifung und Breite b der Schaltafel 2 kann die Abwinklung auch außerhalb der Mitte vorgenommen werden.It is not necessary to bend the diagonal struts 4 in their middle between the bars 5, 6. Depending on the desired stiffening and width b of the formwork panel 2, the bend can also be made outside the center.

Die Diagonalstäbe 4 können in unterschiedlichster Ausgestaltung vorhanden sein, werden jedoch bevorzugt vorab zur einem Gitterträger verbunden.The diagonal bars 4 may be present in various designs, but are preferably connected in advance to a lattice girder.

So zeigt Fig. 6 einen flächigen Gitterträger 17, der aus den gleichen V-förmigen Diagonalstrebenpaaren 4a besteht, die jedoch nur einseitig mit einem Längsstab 5 verbunden sind. Die Verbindung erfolgt bevorzugt im Bereich der freien Enden der Diagonalstrebenpaare, während die Scheitelbereiche unverbunden bleiben. Der Gitterträger 17 wird ebenfalls um die Biegelinie 8 rechtwinklig gebogen und so mit der Schaltafel 2 verbunden, dass sich der Längsstab 5 im senkrechten Bereich 3b befindet.So shows Fig. 6 a flat lattice girder 17, which consists of the same V-shaped diagonal strut pairs 4a, but which are connected only on one side with a longitudinal bar 5. The connection is preferably made in the region of the free ends of the diagonal strut pairs, while the apex areas remain unconnected. The lattice girder 17 is also bent at right angles around the bending line 8 and connected to the formwork panel 2 such that the longitudinal bar 5 is located in the vertical area 3b.

Fig. 7 zeigt einen weiteren flächigen Gitterträger 27, bei dem die Diagonalstreben als Einzelstäbe 4b vorliegen, die jedoch ebenfalls paarweise V-förmig angeordnet sind und mit ihren beidseitigen freien Enden jeweils an einem Längsstab 5, 6 befestigt sind. Fig. 7 shows a further flat lattice girder 27, in which the diagonal struts are present as individual rods 4b, but which are also arranged in pairs V-shaped and are attached with their free ends on both sides of a longitudinal bar 5, 6.

Fig. 8 zeigt ein weiteres Ausführungsbeispiel eines flächigen Gitterträgers 37, bei dem die Diagonalstreben durch eine Schlange 4c, d.h. einen wellenförmig gebogenen Stab, gebildet werden, wobei die Scheitel entweder nur einer Seite, wie dargestellt, oder an beiden Seiten durch einen Längsstab (dargestellt ist der Längsstab 5 des senkrechten Bereiches 3b) miteinander verbunden sind. Fig. 8 shows another embodiment of a flat lattice girder 37, in which the diagonal struts are formed by a snake 4c, ie a wavy curved bar, the vertices either only one side, as shown, or on both sides by a longitudinal bar (shown the longitudinal bar 5 of the vertical portion 3b) are interconnected.

Fig. 9 zeigt ein zweites Ausführungsbeispiel eines erfindungsgemäßen Schalungsteils 100, das bis auf die nachfolgend beschriebenen Einzelheiten dem Schalungsteil 1 entspricht wobei gleiche bzw. vergleichbare Bauteile mit den gleichen Bezugszeichen gekennzeichnet und nicht nochmals erläutert sind. Fig. 9 shows a second embodiment of a formwork part 100 according to the invention, which corresponds to the formwork part 1 except for the details described below wherein the same or comparable components are denoted by the same reference numerals and are not explained again.

Auch das Schalungsteil 100 enthält eine Schaltafel 2 und eine Versteifungseinrichtung 3. Die Versteifungseinrichtung 3 besteht jedoch im dargestellten Ausführungsbeispiel aus einem räumlichen Gitterträger 47. Der räumliche Gitterträger 47 enthält drei Längsstäbe 105, 106 und 107. Die Längsstäbe 105, 106 und 107 sind durch Diagonalstreben 4 miteinander verbunden. Der Gitterträger 47 wird nicht durch Biegen der Diagonalstreben 4 hergestellt, sondern es werden die Längsstäbe 105 und 106 jeweils über eigene Diagonalstreben 4 mit dem mittigen Längsstab 107 verbunden. Im dargestellten Ausführungsbeispiel liegen die Diagonalstreben in Form zweier Diagonalstrebenschlangen 4c vor, wie sie anhand eines flächigen Gitterträgers in Fig. 8 dargestellt sind. Der Gitterträger 47 kann somit beispielsweise dadurch hergestellt werden, dass zwei der in Fig. 8 dargestellten, flächigen Gitterträger über einen weiteren Längs- bzw. Firststab 107 im rechten Winkel miteinander verbunden werden. Dann wird der Gitterträger 47 in gleicher Weise wie die bislang beschriebenen Gitterträger mit der Schaltafel 2 verbunden, wobei der in der Mitte zwischen den beiden Längsstäben 5, 6 liegende Längsstab 107 entlang einer Kante der Schaltafel 2 verläuft und der parallele Bereich 3a mit dem Längsstab 6 endet, der sich entlang der gegenüberliegenden Längskante der Schaltafel 2 erstreckt.However, the formwork part 100 includes a formwork panel 2 and a stiffening means 3. However, the stiffening means 3 consists in the illustrated embodiment of a spatial lattice girder 47. The spatial lattice girder 47 includes three longitudinal bars 105, 106 and 107. The longitudinal bars 105, 106 and 107 are by diagonal struts 4 interconnected. The lattice girder 47 is not made by bending the diagonal struts 4, but the longitudinal bars 105 and 106 are each connected via their own diagonal struts 4 with the central longitudinal bar 107. In the illustrated embodiment are the Diagonal struts in the form of two diagonal struts 4c ago, as they are based on a flat lattice girder in Fig. 8 are shown. The lattice girder 47 can thus be produced, for example, in that two of the in Fig. 8 shown, flat lattice girder over a further longitudinal or ridge bar 107 are connected to each other at right angles. Then, the lattice girder 47 is connected in the same way as the lattice girders described so far with the formwork panel 2, the longitudinal bar 107 lying in the middle between the two longitudinal bars 5, 6 running along one edge of the formwork panel 2 and the parallel area 3a with the longitudinal bar 6 ends, which extends along the opposite longitudinal edge of the formwork panel 2.

In den Fig. 10 bis 13 sind verschiedene Anwendungsbeispiele für die erfindungsgemäßen Schalungsteile 1, 100 ersichtlich, wobei in den Figuren beispielhaft des Schalungsteil 1 dargestellt ist.In the Fig. 10 to 13 different application examples for the formwork parts 1, 100 according to the invention can be seen, wherein in the figures by way of example the formwork part 1 is shown.

Die einfachsten Anwendungen zeigen die Figuren 10 und 11, wobei das Schalungsteil 1 so wie es ist, als Rand- oder Fugenabschalung (Arbeitsfuge oder Dehnungsfuge) für eine Decke oder eine Sohle eingesetzt werden kann. Gemäß Fig. 10 wird einfach der senkrechte Bereich 3b als Standfuß 9 verwendet. Auf diese Weise erstreckt sich die Schaltafel 2 senkrecht zu einem Untergrund 10 und kann zum Herstellen einer Arbeitsfuge oder Dehnungsfuge oder eines Randes eingesetzt werden.The simplest applications show the FIGS. 10 and 11 , wherein the formwork part 1 as it is, as edge or Fugenabschalung (construction joint or expansion joint) can be used for a blanket or a sole. According to Fig. 10 is simply the vertical area 3b used as a base 9. In this way, the formwork panel 2 extends perpendicular to a substrate 10 and can be used for producing a construction joint or expansion joint or a rim.

Die zweite einfache Anwendungsmöglichkeit des Schaltungsteiles 1 zeigt Fig. 11. In diesem Ausführungsbeispiel werden die freien Kanten 2a der Schaltafel 2 und die freie Kante des senkrechten Bereichs 3b als Standfuß 19 benutzt, so dass sich die Schaltafel 2 in einem Winkel von ca. 45° zu einer Unterlage 10 erstreckt und eine unter diesem Winkel verlaufende Arbeitsfuge ausgebildet werden kann.The second simple application of the circuit part 1 shows Fig. 11 , In this embodiment, the free edges 2a of the formwork panel 2 and the free edge of the vertical portion 3b are used as a stand 19, so that the formwork panel 2 extends at an angle of approximately 45 ° to a base 10 and extending at this angle working joint can be trained.

Die Fig. 12 und 13 zeigen eine erweiterte Verwendung des Schaltungsteiles 1,100, wobei wiederum das Schalungsteil 1 beispielhaft dargestellt ist.The FIGS. 12 and 13 show an expanded use of the circuit part 1,100, again the formwork part 1 is exemplified.

Fig.12 zeigt ein Schalungselement 11 mit einem Fugenblech 12. Das Schalungselement 11 besteht aus zwei Schalungsteilen 1, die spiegelbildlich mit zueinander benachbarten parallelen Bereichen 3a gegeneinander gestellt und über das dazwischen liegende Fugenblech 12 miteinander verbunden, bevorzugt miteinander verschweißt (Schweißpunkt S), sind. Im dargestellten Ausführungsbeispiel weisen die Schaltafeln 2 beider Schalungsteile 1 in die gleiche Richtung. Es ist jedoch auch möglich, eines der Schalungsteile 1 umgedreht anzuordnen, so dass die Schaltafeln 2 der beiden Schalungsteile 1 in einander entgegengesetzte Richtungen weisen und sich die parallelen Bereiche 3a beider Schalungsteile diagonal am Fugenblech 12 gegenüberliegen. Figure 12 The formwork element 11 consists of two formwork parts 1, the mirror image with adjacent parallel areas 3a against each other and placed on the intermediate joint plate 12th connected to each other, preferably welded together (welding point S), are. In the illustrated embodiment, the formwork panels 2 of both formwork parts 1 in the same direction. However, it is also possible to arrange one of the formwork parts 1 upside down, so that the formwork panels 2 of the two formwork parts 1 facing each other in opposite directions and the parallel portions 3a of both formwork parts diagonally opposite the joint plate 12.

Fig. 13 zeigt eine weitere Fugenschalung 21, die unter Verwendung zweier Schalungsteile 1 hergestellt wurde. Diese Fugenschalung 21 ist zur Aufnahme eines elastischen Fugenbandes ausgebildet. Zum Herstellen der Fugenschalung 21 werden die beiden Schalungsteile 1, wiederum spiegelbildlich zueinander mit gegeneinander weisenden senkrechten Bereichen 3b, diesmal jedoch im Abstand zueinander, angeordnet und mit Hilfe wenigstens eines Bügels 13 miteinander verbunden. Der Bügel 13 weist einen im Wesentlichen U-förmigen Bereich 13a auf, der den erforderlichen Freiraum für das nicht dargestellte Fugenband schafft und in seinem inneren Bereich im Wesentlichen parallel zu den senkrechten Breichen 3b verläuft. Der Bügel 13 weist weiterhin zwei Schenkel 13b, 13c auf, die im Wesentlichen parallel zu den parallelen Bereichen 3a beider Schalungsteile 1 verlaufen und sich bevorzugt über die gesamte Breite der parallelen Bereiche 3a beider Schalungsteile 1 erstrecken. Auch die Bügel sind, falls aus schweißbarem Material, an den senkrechten und/oder parallelen Bereichen und/oder der Schaltafel 2 angeschweißt. Im Abstand zwischen den Schalungsteilen 1 und/oder in den U-förmigen Bereichen 13a der Bügel 13 ist eine bekannte Fugenbandhalterung, z. B. des aus der DE 201 18 098 U1 beschriebenen Typs, eingesetzt. Fig. 13 shows a further joint formwork 21, which was prepared using two formwork parts 1. This joint form 21 is designed to receive an elastic joint tape. To produce the joint formwork 21, the two formwork parts 1, in turn mirror images of each other with mutually facing vertical areas 3b, but this time at a distance from each other, arranged and connected to each other by means of at least one bracket 13. The bracket 13 has a substantially U-shaped portion 13a, which creates the necessary clearance for the joint tape, not shown, and extends in its inner region substantially parallel to the vertical Breichen 3b. The bracket 13 further has two legs 13b, 13c which extend substantially parallel to the parallel areas 3a of both formwork parts 1 and preferably extend over the entire width of the parallel areas 3a of both formwork parts 1. The brackets are, if made of weldable material, welded to the vertical and / or parallel areas and / or the formwork panel 2. In the distance between the formwork parts 1 and / or in the U-shaped portions 13 a of the bracket 13 is a known joint tape holder, z. B. from the DE 201 18 098 U1 described type used.

In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können beispielsweise die Gitterträger abgewandelt werden. So ist es nicht unbedingt notwendig, die Längsstäbe der Gitterträger an unterschiedlichen Seiten des Umfangs der Diagonalstreben zu befestigen (wie dies in den Zeichnungen dargestellt ist). Beide Längsstäbe können viel mehr an den gleichen Seiten angeordnet sein. Auch die Anordnung und die Reihenfolge der Diagonalstreben kann abgewandelt sein. So können beispielsweise jeweils zwei oder noch mehr benachbarte Diagonalstreben in die gleiche Richtung weisen. Es können weitere Längsstäbe eingesetzt werden. Es können schlangenförmige Stücke verwendet werden, die über die gesamte Länge des Gitterträgers zusammengesetzt werden. Weitere Abwandlungen sind denkbar. Die Größe und Form der Schaltafel kann an den bestimmten Einsatzzweck des Schalungsteils angepasst werden. Gegebenenfalls kann die Versteifungseinrichtung zusätzliche Streben oder dgl. enthalten. Schließlich muss zur Herstellung des erfindungsgemäßen Schalungsteils der Gitterträger nicht zunächst vorgefertigt sein, sondern kann sich auch im Verlauf der Befestigung der Diagonalstreben und Längsstäbe an der Schaltafel ergeben. Schließlich müssen nicht alle äußeren Enden der Diagonalstreben miteinander verbunden werden. Auch kann das Schalungsteil hochkant, d. h. auf den Stirnseiten des parallelen Bereichs oder der Schaltafel und des senkrechten Bereichs, stehend als Rand- oder Fugenabschalung, z. B. für Wände, eingesetzt werden.In a modification of the described and illustrated embodiments, for example, the lattice girders are modified. Thus, it is not absolutely necessary to attach the longitudinal bars of the lattice girders to different sides of the perimeter of the diagonal struts (as shown in the drawings). Both longitudinal bars can be arranged much more on the same sides. The arrangement and the order of the diagonal braces may be modified. For example, two or even more adjacent diagonal struts can point in the same direction. It can be used more longitudinal bars. Snake-shaped pieces can be used, which are assembled over the entire length of the lattice girder. Further modifications are conceivable. The size and shape of the formwork panel can be adapted to the particular application be adapted to the formwork part. Optionally, the stiffener may include additional struts or the like. Finally, for the production of the formwork part according to the invention, the lattice girder does not have to be prefabricated at first, but can also result in the course of attachment of the diagonal struts and longitudinal bars to the formwork panel. Finally, not all outer ends of the diagonal struts need to be connected together. Also, the formwork part upright, ie on the front sides of the parallel area or the formwork panel and the vertical area, standing as edge or Fugenabschalung, z. B. for walls, are used.
