Definitions
- 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.
- 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.
- 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.
- the invention has for its object to provide a formwork part that is easy and easy to manufacture, and versatile.
- 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.
- 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.
- 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.
- 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.
- a perforated formwork material is used, which allows use of the formwork part as a lost formwork.
- 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.
- the formwork part 1 contains a formwork panel 2 made of a comparatively thin-walled material.
- the material for the formwork panel 2 any material used for peeling, but preferably the formwork panel 2 consists of a perforated material, such as an expanded sheet metal, a perforated plate, a grid mat, or other openwork materials, whereby the formwork part 1 particularly to the use as lost formwork is adjusted.
- 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.
- 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.
- 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 "substantially” is intended here to describe a desired angle of 90 ° to the formwork panel 2, but also include angle deviations that arise, 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.
- Both the parallel region 3a and the vertical region 3b contain diagonal struts 4.
- 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.
- 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.
- 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.

- 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.
- 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.
- 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.

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
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
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
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 directly or indirectly connected 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.

Aus den
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
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
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

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
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

So zeigt
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

Die
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.
