Description

Die Erfindung bezieht sich auf eine Schalungsplatte zum Herstellen einer Schalung mit offenem Boden, der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a formwork panel for producing a formwork with an open bottom, of the type explained in the preamble of claim 1.

Eine derartige Schalungsplatte ist aus der DE-PS 36 01 882 bekannt. Die bekannte Schalungsplatte besteht aus einem Streifen aus einem mit Kunststoffolie beschrumpftem Gitterwerk aus Stahlstäben. Zum Herstellen beispielsweise einer Schalung für ein Streifenfundament mit offenem Boden muß für jede der Seitenwände der Schalung eine eigene Schalungsplatte verwendet werden. Die Schalungsplatten werden bei der Herstellung oder kurz vor Verwendung L-förmig abgewinkelt, so daß eine Standfläche zum Aufstellen der Schalungswandung auf dem Untergrund geschaffen wird. Trotzdem müssen die bekannten Schalungswände noch mit dem Untergrund und/oder miteinander verbunden werden, um die nötige Standfestigkeit der Schalung sicherzustellen. Darüber hinaus ist die Kunststoffolie nicht formstabil, obwohl sie durch das Aufschrumpfen das Gitterwerk wesentlich straffer überspannt als dies mit einer nur aufgelegten und festgeschweißten Kunststoffolie möglich wäre.Such a formwork panel is known from DE-PS 36 01 882. The known formwork panel consists of a strip of a latticework made of steel bars shrunk with plastic film. To produce, for example, formwork for a strip foundation with an open bottom, a separate formwork plate must be used for each of the side walls of the formwork. The formwork panels are angled L-shaped during manufacture or shortly before use, so that a footprint is created for setting up the formwork wall on the ground. Nevertheless, the known formwork walls still have to be connected to the subsurface and / or to one another in order to ensure the necessary stability of the formwork. In addition, the plastic film is not dimensionally stable, although it shrinks the latticework much more tightly than would be possible with a plastic film that was only attached and welded on.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Schalungsplatte für eine einfach und kostengünstig her- und aufzustellende Schalung zu schaffen.The invention is therefore based on the object of creating a formwork panel for formwork which can be easily and inexpensively produced and erected.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.

Aus der erfindungsgemäßen Schalungsplatte kann auf einfache Weise und ohne zusätzlich Befestigungs- und Verspannungsarbeiten die gewünschte Schalung durch einfaches Hochbiegen der Seitenwände hergestellt werden. Bei der Herstellung können lose Querstäbe verwendet werden, die durch die Seitenwände aus formstabilem Material im vorbestimmten Abstand und in der vorbestimmten Lage zueinander gehalten werden.From the formwork panel according to the invention the desired formwork can be produced in a simple manner and without additional fastening and tensioning work by simply bending up the side walls. Loose cross bars can be used in the production, which are held by the side walls made of dimensionally stable material at a predetermined distance and in the predetermined position from one another.

Von besonderem Vorteil ist die in Anspruch 2 beschriebene Verwendung von Waffel- und Schuppenblech als formstabiles Material. Diese Bleche wurden bislang beispielsweise zum Herstellen von rutschfesten Trittstufen im Industriebereich verwendet. Diese Bleche weisen eine geprägte Oberfläche auf, die an der einen Blechseite Ausnehmungen und an der anderen Blechseite Erhebungen zeigt. Im Falle von Schuppenblechen enthalten die Prägungen darüber hinaus Durchgangsöffnungen (etwa wie ein Reibeisen), die jedoch nicht so groß sind, daß Beton in merklichen Mengen hindurchtreten kann. Durch die Verwendung dieser geprägten Bleche wird an den Seitenflächen des fertiggegossenen Betonteiles eine kontrollierte Rauhigkeit erzielt, die eine gute Haftbrücke zum Angießen weiterer Betonteile darstellt.Of particular advantage is the use of waffle and flake sheet described in claim 2 as a dimensionally stable material. So far, these sheets have been used, for example, to produce non-slip steps in the industrial sector. These sheets have an embossed surface which shows recesses on one sheet side and elevations on the other sheet side. In the case of scale plates, the embossments also contain through openings (such as a grater), but they are not so large that concrete can pass through in noticeable amounts. By using these embossed sheets, a controlled roughness is achieved on the side surfaces of the cast concrete part, which is a good adhesive bridge for casting additional concrete parts.

Es ist jedoch auch möglich, gemäß Anspruch 3 für die Streifen ein Streckmetall, insbesondere ein feinmaschiges Streckgitter zu verwenden.However, it is also possible to use expanded metal, in particular a fine-mesh expanded metal, for the strips.

Normalerweise reicht es aus, die Querstäbe gemäß Anspruch 4 durch die Streifen des formstabilen Materials in ihrem vorbestimmten Abstand zu halten. Es ist jedoch möglich, gemäß Anspruch 5 die Querstäbe vor oder nach dem Anbringen der Streifen des formstabilen Materials durch Längsstäbe zu versteifen.Normally, it is sufficient to keep the cross bars according to claim 4 by the strips of the dimensionally stable material at their predetermined distance. However, it is possible, according to claim 5, to stiffen the transverse bars before or after the strips of the dimensionally stable material have been attached by longitudinal bars.

Die Längsstäbe werden gemäß Anspruch 6 bevorzugt an besonders beanspruchten Stellen, z. B. an einer Biegung, angeordnet, oder es wird, gemäß Anspruch 7, von vornherein ein Metallgitter verwendet.The longitudinal bars are preferably according to claim 6 at particularly stressed locations, for. B. arranged on a bend, or it is used according to claim 7, from the outset a metal grid.

Die erfindungsgemäße Schalung wird hergestellt, indem auf parallelliegende flache oder bereits vorgebogene Querstäbe an den später den Seitenwänden entsprechenden Stellen die Streifen aus dem formstabilen Material entweder direkt (Anspruch 8) oder zusammen mit zusätzlichen Längsstäben (Anspruch 9) aufgebracht werden.The formwork according to the invention is produced by applying the strips of the dimensionally stable material either directly (claim 8) or together with additional longitudinal bars (claim 9) to parallel flat or already pre-bent cross bars at the points later corresponding to the side walls.

Aus Fig. 1 ist eine erfindungsgemäße Schalungsplatte 1 ersichtlich, die eine Mehrzahl parallelliegender Querstäbe 2 aus Baustahl aufweist. Länge, Durchmesser und Abstand der Querstäbe 2 werden entsprechend den Abmessungen und Anforderungen der gewünschten Schalung ausgewählt. Die jeweils miteinander fluchtenden, freien Enden der Querstäbe 2 sind auf beiden Seiten mit jeweils einem Streifen 3 aus einem formstabilen Waffelblech miteinander verbunden, wobei die zwischen den Streifen 3 liegenden Bereiche der Querstäbe 2 unbedeckt bleiben. Die Breite und Länge der Streifen 3 entspricht etwa den Abmessungen der Seitenwände des gewünschten Schalungsteils.1 shows a formwork panel 1 according to the invention, which has a plurality of parallel transverse bars 2 made of structural steel. Length, diameter and distance of the cross bars 2 are according to the dimensions and Requirements of the desired formwork selected. The respectively aligned, free ends of the cross bars 2 are connected on both sides to each other with a strip 3 of a dimensionally stable waffle plate, the areas of the cross bars 2 lying between the strips 3 remaining uncovered. The width and length of the strips 3 correspond approximately to the dimensions of the side walls of the desired formwork part.

Fig. 2 zeigt ein weiteres Ausführungsbeispiel einer Schalungsplatte 1', die bereits in ein U-förmiges Schalungsteil gebogen wurde, wie sie beispielsweise für ein Balken- oder Streifenfundament verwendet werden. Die Schalungsplatte 1' wurde derart gebogen, daß die Streifen 3' sich im Bereich der Seitenwände befinden, während der unbedeckte Bereich der Querstäbe 2' als Boden auf einem Untergrund aufsteht. Gegebenenfalls können die Stirnseiten durch übliche Schalungsmittel verschlossen werden.Fig. 2 shows a further embodiment of a formwork panel 1 ', which has already been bent into a U-shaped formwork part, such as are used for example for a beam or strip foundation. The formwork panel 1 'was bent in such a way that the strips 3' are located in the area of the side walls, while the uncovered area of the cross bars 2 'stands as the floor on a surface. If necessary, the end faces can be closed using conventional formwork.

Die Streifen 3' bestehen, wie auch Fig. 3 zeigt, aus einem Schuppenblech, das an die nach innen weisenden Seiten der Querstäbe 2' angeschweißt wurde. Die Streifen 3' aus Schuppenblech erstrecken sich von den freien Enden der Querstäbe 2' bis in den Bereich der Biegung. An der Außenseite der Querstäbe 2' sind Längsstäbe 4 angeschweißt. Im dargestellten Ausführungsbeispiel sind pro Seitenwand zwei Längsstäbe vorgesehen, und zwar verbindet einer der Längsstäbe 4 die Querstäbe 2' im Bereich ihrer freien Enden und der andere der Längsstäbe 4 den Bereich nahe der Biegung. Es ist jedoch auch möglich, weitere Längsstäbe 4 oder von vornherein ein Metallgitter zu verwenden (vergl. auch Fig. 5).The strips 3 'consist, as also shown in FIG. 3, of a scale plate which has been welded to the inwardly facing sides of the cross bars 2'. The strips 3 'made of scale plate extend from the free ends of the cross bars 2' into the region of the bend. Longitudinal bars 4 are welded to the outside of the cross bars 2 '. In the illustrated embodiment, two longitudinal bars are provided per side wall, namely one of the longitudinal bars 4 connects the transverse bars 2 'in the area of their free ends and the other of the longitudinal bars 4 connects the area near the bend. However, it is also possible to use further longitudinal bars 4 or a metal grid from the outset (see also FIG. 5).

Wie Fig. 3 zeigt, sind die Streifen 3' aus Schuppenblech bei 5 mit den Querstäben 2' verschweißt und derart angeordnet, daß die aus der Ebene des Streifens 3' heraustretenden Schuppen 6 in das Innere der Schalung gerichtet sind.As shown in FIG. 3, the strips 3 'of scale sheet are welded to the cross bars 2' at 5 and arranged in such a way that the scales 6 emerging from the plane of the strip 3 'are directed into the interior of the formwork.

In Fig. 4 ist eine weitere Verwendungsmöglichkeit der erfindungsgemäßen Schalungsplatte für eine in Umfangsrichtung geschlossene Schalung ersichtlich, für die sowohl die Schalungsplatte 1 (wie dargestellt) als auch die Schalungsplatte 1' verwendet werden kann. Für diese Schalung werden zwei in ihren Abmessungen aneinander angepaßte Schalungsplatten 1 zu jeweils einem U-förmigen Schalungsteil gebogen und um 90o gegeneinander versetzt ineinandergestellt, so daß jeweils ein Streifen 3 der ersten Schalungsplatte 1 den unbedeckten Bereich der Querstäbe 2 der anderen Schalungsplatte 1 überdeckt. Für diesen Anwendungszweck werden die Schalungsplatten 1 zweckmäßigerweise derart gebogen, daß jeder der den unbedeckten Bereichen der Querstäbe 2 anliegende Rand des Streifens 3 leicht abgewinkelt wird, so daß sich die Streifen 3 beim Ineinanderstellen der gebogenen Schalungsplatten 1 gegenseitig in den Ecken überlappen, so daß dort kein Beton austreten kann.4 shows a further possible use of the formwork panel according to the invention for a formwork which is closed in the circumferential direction, for which both the formwork panel 1 (as shown) and the formwork panel 1 'can be used. For this formwork, two formwork panels 1 which are adapted to one another in terms of their dimensions are bent to form a U-shaped formwork part and are offset from one another by 90 o , so that one strip 3 of the first formwork panel 1 covers the uncovered area of the cross bars 2 of the other formwork panel 1. For this purpose, the formwork panels 1 are appropriately bent such that each of the edges of the strip 3 lying against the uncovered areas of the cross bars 2 is angled slightly, so that the strips 3 overlap one another in the corners when the curved formwork panels 1 are placed one inside the other, so that there no concrete can escape.

Fig. 5 zeigt eine weitere Schalungsplatte 10, deren Querstäbe 12 zusammen mit Längsstäben 14 ein regelmäßiges Metallgitter bilden. Die Streifen 13 entsprechen den Streifen der vorangegangenen Ausführungsbeispiele und sind direkt mit den Querstäben 12 des Metallgitters verbunden. Die Schaltungsplatte 10 wurde derart gebogen, daß die Längsstäbe 14 nach außen weisen. Als Metallgitter kann auch eine herkömmliche Baustahlmatte verwendet werden.Fig. 5 shows a further formwork panel 10, the cross bars 12 together with longitudinal bars 14 form a regular metal grid. The strips 13 correspond to the strips of the previous exemplary embodiments and are connected directly to the cross bars 12 of the metal grid. The circuit board 10 was bent in such a way that the longitudinal bars 14 point outwards. A conventional structural steel mat can also be used as the metal grid.

Die Herstellung der Schalungsplatte bzw. des Schalungsteils erfolgt bevorzugt automatisch, wobei die gewünschte Anzahl von Querstäben in paralleler Ausrichtung einer Schweißvorrichtung zugeführt werden, in der die Streifen aus formstabilem Material aufgeschweißt, aufgepunktet oder sonstwie aufgebracht werden. Nach oder vor dem Aufbringen der Streifen werden die Querstäbe in der gewünschten Länge geschnitten. Anschließend werden die Querstäbe, gegebenenfalls zusammen mit dem unteren Rand der Streifen gebogen, so daß ein U-förmiges Schalungsteil entsteht. Gegebenenfalls kann jedoch die Biegung vor dem Aufbringen der Streifen erfolgen.The formwork panel or the formwork part is preferably produced automatically, the desired number of crossbars being fed in parallel alignment to a welding device in which the strips of dimensionally stable material are welded, dotted or otherwise applied. After or before applying the strips, the cross bars are cut to the desired length. The cross bars are then bent, possibly together with the lower edge of the strips, so that a U-shaped formwork part is created. If necessary, however, the bending can take place before the strips are applied.

Die Längsstäbe können vor oder nach den Streifen auf die Querstäbe aufgeschweißt werden. Bei Verwendung eines Metallgitters wird dieses zunächst vorgefertigt und erst anschließend mit den Streifen verbunden. Dabei werden die Streifen bevorzugt direkt auf die Querstäbe aufgeschweißt. Es ist jedoch auch möglich, die Streifen auf die Längsstäbe zu schweißen, so daß ihre Verbindung mit den Querstäben über die Längsstäbe erfolgt.The longitudinal bars can be welded onto the cross bars before or after the strips. When using a metal grid, this is first prefabricated and only then connected to the strips. The strips are preferably welded directly onto the cross bars. However, it is also possible to weld the strips to the longitudinal bars so that they are connected to the transverse bars via the longitudinal bars.

In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können die anhand der einzelnen Figuren gezeigten Einzelheiten untereinander ausgetauscht werden. So kann beispielsweise auch der Streifen im Ausführungsbeispiel nach den Fig. 2 oder 5 in der in Fig. 4 gezeichneten Weise abgewinkelt sein. Statt des Waffel- oder des Schuppenblechs kann für die Streifen auch ein Streckmetall, insbesondere ein handelsübliches, feinmaschiges Streckgitter, oder irgendein anderes geeignetes, formstabiles Material eingesetzt werden. Die Anzahl der Quer- oder Längsstäbe kann gegenüber der zeichnerischen Darstellung erhöht bzw. verringert werden. Werden dünnere Querstäbe verwendet, so kann das Schalungsteil gegebenenfalls auch direkt auf der Baustelle gebogen werden.In a modification of the exemplary embodiments described and drawn, the details shown on the basis of the individual figures can be interchanged. For example, the strip in the exemplary embodiment according to FIGS. 2 or 5 can also be angled in the manner shown in FIG. 4. Instead of the waffle or scale plate, an expanded metal, in particular a commercially available, fine-mesh expanded metal mesh, or any other suitable, dimensionally stable material can also be used for the strips. The number of transverse or longitudinal bars can be increased or decreased compared to the graphic representation. If thinner cross bars are used, this can Formwork part may also be bent directly on site.
