Definitions

  • the invention relates to a formwork panel with edge webs that protrude approximately at right angles to the formwork skin from a flat extruded profile made of aluminum, an aluminum alloy or similar light metal, on which edge webs stop surfaces run at right angles to the formwork skin, on which, in the use position, stop surfaces of edge webs of neighboring formwork panels are indirect or abut directly and on the rear faces opposite the stop surfaces engage connecting means in the form of clips for mutually fastening the adjoining edge webs, the extruded profiles having chambers or the like extending in the longitudinal direction of the edge webs and being enclosed on all sides by walls, and wherein one edge of the edge web for connecting a formwork skin has an angular space and the parallel, distant edge of the formwork skin in the use position is encompassed by the clip, the point of attack for the clip is a groove or groove running on the rear of the edge web, which is arranged approximately in the middle between the edges of the edge web.

Abstract

The proposed shuttering panel (1) has edge struts (3) formed from a flat extruded section made of aluminium, an aluminium alloy or another light metal, ensuring both lightness and rigidity. The contact points for clamps (7) for the mutual securing of such edge struts (3) of adjacent panels (1) are at a distance from the shuttering lining (2) at a site where the edge struts (3) have a full cross section and the hollow spaces (8) on either side of these contact points are not at risk of being deformed by the pressure exerted by the fixing clamps (7). A channel (14) or groove is provided with which the clamp can engage to ensure that this contact point is actually used. This makes it possible to use the same clamp (7) which serves for edge struts made of flat material with a central bead so that shuttering panels made of different materials and provided with such edge struts can be combined.

Description

Die Erfindung betrifft eine Schaltafel mit an ihren Rändern etwa rechtwinklig zur Schalhaut abstehenden Randstegen aus einem flachen Strangpreßprofil aus Aluminium, einer Aluminiumlegierung oder dergleichen Leichtmetall, an welchen Randstegen Anschlagflächen rechtwinklig zur Schalhaut verlaufen, an denen in Gebrauchsstellung Anschlagflächen von Randstegen von Nachbar-Schaltafeln mittelbar oder unmittelbar anliegen und an deren den Anschlagflächen gegenüberliegenden Rückseiten Verbindungsmittel in Form von Klammer zum gegenseitigen Befestigen der aneinanderliegenden Randstege angreifen, wobei die Strangpreßprofile in Längsrichtung der Randstege verlaufende Kammern oder dergleichen Hohlräume haben, die von Wandungen allseitig umschlossen sind, und wobei der eine Rand des Randsteges zum Anschließen einer Schalhaut einen Winkelraum aufweist und der damit parallele, von der Schalhaut abliegende Rand in Gebrauchsstellung von der Klammer umgriffen ist, wobei die Angriffsstelle für die Klammer eine an der Rückseite des Randsteges verlaufende Rinne oder Nut ist, die etwa in der Mitte zwischen den Rändern des Randsteges angeordnet ist.The invention relates to a formwork panel with edge webs that protrude approximately at right angles to the formwork skin from a flat extruded profile made of aluminum, an aluminum alloy or similar light metal, on which edge webs stop surfaces run at right angles to the formwork skin, on which, in the use position, stop surfaces of edge webs of neighboring formwork panels are indirect or abut directly and on the rear faces opposite the stop surfaces engage connecting means in the form of clips for mutually fastening the adjoining edge webs, the extruded profiles having chambers or the like extending in the longitudinal direction of the edge webs and being enclosed on all sides by walls, and wherein one edge of the edge web for connecting a formwork skin has an angular space and the parallel, distant edge of the formwork skin in the use position is encompassed by the clip, the point of attack for the clip is a groove or groove running on the rear of the edge web, which is arranged approximately in the middle between the edges of the edge web.

Aus einem Prospekt der Fa. MEVA GmbH "ALU STAR", Technische Anleitung, Mai 1992, ist eine derartige Schaltafel bereits bekannt. Die als Strangpreßprofil ausgebildeten Randstege haben dabei eine relativ große Dicke, so daß entsprechend große Klammern daran angreifen müssen und aufgrund ihres hohlen Querschnittes zur inneren Aussteifung ein parallel zu der Schalhaut verlaufender zusätzlicher Steg eingeformt sein muß, der sich im Bereich der Rinne oder Nut befindet. Der große Querschnitt verursacht als solcher ein entsprechendes Gewicht und vor allem müssen entsprechend große Klammern mit entsprechend hohem Gewicht zum Verbinden derartiger Schaltafeln verwendet werden.Such a switch panel is already known from a brochure from MEVA GmbH "ALU STAR", Technical Instructions, May 1992. The edge webs designed as an extruded profile have a relatively large thickness, so that correspondingly large brackets have to act on them and, due to their hollow cross-section for internal stiffening, an additional web running parallel to the formlining must be formed, which is located in the region of the channel or groove. As such, the large cross-section causes a corresponding weight and, above all, correspondingly large brackets with a correspondingly high weight must be used to connect such formwork panels.

Zwar sind aus der Praxis auch bereits Schaltafeln bekannt, bei denen ein Leichtmetall zur Herstellung der Randstege vorgesehen ist, wobei der Querschnitt relativ flachgehalten ist. Damit diese ebenfalls aus der Praxis bekannten Randstege die erforderliche Steifigkeit haben, sind sie ebenfalls als Strangpreßprofil mit Hohlräumen ausgebildet. Dieses bekannte Strangpreßprofil hat dabei an seiner Rückseite zwei Angriffsstellen für eine Klammer, die jeweils nahe den beiden Rändern dieses Strangpreßprofiles liegen, nämlich einerseits nahe dem an der Schalhaut befindlichen Rand und andererseits nahe dem davon abliegenden Rand dieses Randsteges.It is true that formwork panels are already known from practice in which a light metal is provided for producing the edge webs, the cross section being kept relatively flat. So that these edge webs, which are also known from practice, have the required rigidity, they are also designed as an extruded profile with cavities. This known extruded profile has two points of attack for a clip on its rear side, which are each close to the two edges of this extruded profile, namely on the one hand near the edge located on the formlining and on the other hand near the edge of this edge web remote therefrom.

Die Angriffsstellen übergreifen dabei die in dem Strangpreßprofil befindlichen Hohlräume, so daß bei einer hohen Klammer-Kraft die Gefahr besteht, daß das aus Leichtmetall bestehende Hohlprofil des Randsteges eingedrückt wird. Damit diese Gefahr möglichst gering ist, ohne jedoch ausgeschaltet werden zu können, greift die Klammer bis in den Bereich des Randsteges, der sich unmittelbar an der Rückseite der Schalhaut befindet, so daß sich die Befestigung des Randsteges an dem stirnseitigen Rand der Schalhaut befinden muß. Es ist also Vorsorge dafür zu treffen, daß den Randsteg im Bereich der Schalhaut durchsetzende Befestigungsmittel die in diesem Bereich befindliche gegenseitige Anschlagfläche nicht uneben und vor allem undicht machen.The points of attack overlap the cavities located in the extruded profile, so that with a high clamping force there is a risk that the hollow profile of the edge web consisting of light metal will be pressed in. So that this risk is as low as possible, but without being able to be switched off, the clamp reaches into the area of the edge web, which is located directly on the back of the formwork skin, so that the fastening of the edge web must be on the front edge of the formwork skin. Care must therefore be taken to ensure that fastening means penetrating the edge web in the area of the formwork skin do not make the mutual stop surface located in this area uneven and, above all, leaky.

Die der Schalhaut ferne Angriffsstelle der Klammer ist im Querschnitt gesehen konisch gestaltet, so daß eine gewisse Zentrierwirkung, gleichzeitig aber auch eine Kraftkomponente quer zu der dort befindlichen Begrenzungswand eines der Hohlräume des Strangpreßprofiles entsteht. Somit kann bei hohen Kräften beim Verklammern eine Verformung auch in diesem Bereich nicht ausgeschlossen werden. Soll eine solche Verformung des Strangpreßprofiles im Bereich seiner die Hohlräume begrenzenden Wandungen ausgeschlossen werden, müssen die von der Klammern ausgehenden Kräfte begrenzt werden oder die Wandungen des Randsteges entsprechend stark ausgebildet werden, was wiederum zu einem entsprechend höheren Gewicht der Schaltafel führt.The point of attack of the clamp remote from the formwork skin is conical in cross-section, so that a certain centering effect, but at the same time a force component arises transversely to the boundary wall located there, of one of the cavities of the extruded profile. In this way, deformation cannot be ruled out in this area even with high clamping forces. If such a deformation of the extruded profile in the region of its walls delimiting the cavities is to be excluded, the forces emanating from the clamps must be limited or the walls of the edge web are made correspondingly strong, which in turn leads to a correspondingly higher weight of the formwork panel.

Während bei dem im Querschnitt relativ breiten Strangpreßprofil eine entsprechend breite Anlagefläche der Schalhaut entsteht, aber in Kauf genommen werden muß, daß entsprechend große Klammern erforderlich sind, entsteht bei dem im Querschnitt flachen Strangpreßprofil an dem schalhautnahen Rand dieses Randsteges nur eine sehr geringe Anschlagfläche.While the relatively wide cross-section of the extruded profile creates a correspondingly wide contact surface of the formlining, but it must be accepted that correspondingly large brackets are required, the flat cross-section of the extruded profile creates only a very small stop surface on the edge of this edge web near the formlining.

In beiden Fällen muß die Befestigung deshalb in die Schmalseite der Schalhaut eingeführt werden oder bei dem breiten Strangpreßprofil von der dem Beton zugewandten Seite der Schalhaut t aus eingebracht werden. Dies stellt entweder eine weniger stabile Befestigung oder eine Verletzung der dem Beton zugewandten Schalhaut dar.In both cases, the fastening must therefore be introduced into the narrow side of the formlining or, in the case of the wide extruded profile, be introduced from the side of the formlining t facing the concrete. This is either a less stable attachment or an injury to the formwork facing the concrete.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Schaltafel der eingangs genannten Art zu schaffen, bei welcher die Klemmkräfte quer zu dem Randsteg außerhalb der Wandungen der Hohlräume eingeleitet werden können, wobei insbesondere auch eine Kupplung mit Randstegen aus Flachmaterial aus Stahl, insbesondere mit einer mittleren Sicke möglich sein soll, wobei gleichzeitig die Befestigung der Randstege an der Schalhaut verbessert ist, trotzdem aber relativ kleine Klammern benutzt werden können.The invention is therefore based on the object to provide a formwork panel of the type mentioned, in which the clamping forces can be introduced transversely to the edge web outside the walls of the cavities, in particular also a coupling with edge webs made of flat material made of steel, in particular with a medium one Beading should be possible, at the same time the attachment of the edge webs to the formwork skin is improved, but relatively small brackets can still be used.

Zur Lösung dieser Aufgabe ist eine Schaltafel der eingangs erwähnten Art dadurch gekennzeichnet, daß der Randsteg in dem gesamten Bereich der Rinne oder Nut einen Vollquerschnitt hat, daß beidseits der Rinne im Inneren des Randsteges Hohlräume verlaufen und daß der die Schalhaut aufnehmende Winkelraum an dem schalhautnahen Rand des Randsteges einen im Querschnitt verlängerten,
einstückigen, an der Rückseite der Schalhaut anliegenden Steg aufweist, der die Fortsetzung der Begrenzungswand des schalhautnahen Hohlraumes ist und als Befestigungsflansch für die Schalhaut dient.
To solve this problem, a formwork panel of the type mentioned at the outset is characterized in that the edge web has a full cross-section in the entire region of the channel or groove, that cavities run on both sides of the channel in the interior of the edge web and that the angular space accommodating the formlining is on the edge near the formlining of the edge web an elongated cross section,
has a one-piece web, which rests against the back of the formlining, which is the continuation of the boundary wall of the cavity close to the formlining and serves as a fastening flange for the formlining.

Da der Randsteg ein flaches Strangpreßprofil ist, genügen relativ kleine Klammern, um die Randstege benachbarter Schaltafeln erfassen zu können. Dabei können auch Schaltafeln angeschlossen werden, deren Randstege aus Flachmaterial, aus Stahl bestehen, wie sie in der DE-A-41 03 775.8 beschrieben sind. Es ergibt sich also eine vielfältige Anwendung. Vorteilhaft ist dabei, daß die Klammer an einer Nut etwa in der Mitte des Randsteges angreift, um die Randstege aneinanderpressen zu können.Since the edge web is a flat extruded profile, relatively small brackets are sufficient to be able to grasp the edge webs of adjacent formwork panels. Formwork panels can also be connected, the edge webs of which consist of flat material made of steel, as described in DE-A-41 03 775.8. So there is a variety of applications. It is advantageous that the clip engages a groove approximately in the middle of the edge web in order to be able to press the edge webs together.

Da in diesem Bereich ein Vollquerschnitt vorgesehen ist und sich die Hohlräume beidseits dieses die Rinne oder Nut aufweisenden Bereiches befinden, werden diese Hohlräume und ihre Wandungen nicht von der Klammer in dem Sinne beaufschlagt, daß sie eingedrückt werden könnten. Selbst wenn sehr hohe Klammerkräfte aufgebracht werden, ist keine Verformung der die Hohlräume begrenzenden Wandungen zu erwarten. Da der Angriff der Klammer mit Abstand zur Schalhaut erfolgt, ist auch im Bereich der Schalhaut genügend Platz für eine Befestigung dieser Schalhaut am Randsteg beispielsweise an der Rückseite der Schalhaut.Since a full cross section is provided in this area and the cavities are located on either side of this area having the groove or groove, these cavities and their walls are not acted upon by the clamp in the sense that they could be pressed in. Even if very high clamping forces are applied, no deformation of the walls delimiting the cavities is to be expected. Since the clamp is attacked at a distance from the formlining, there is also enough space in the area of the formwork for fastening this formwork to the edge web, for example to the rear of the formwork.

Dabei ist von erheblichem Vorteil, daß der die Schalhaut aufnehmende Winkelraum an dem schalhautnahen Rand des Randsteges einen im Querschnitt verlängerten, einstückigen, an der Rückseite der Schalhaut anliegenden Steg aufweist, der die Fortsetzung der Begrenzungswand des schalhautnahen Hohlraumes ist und als Befestigungsflansch für die Schalhaut dient. Die nahe der Schalhaut parallel zu dieser und zu der zu betonierenden Fläche verlaufende Begrenzungswand eines Hohlraumes des Strangpreßprofiles muß also nicht als zusätzliche Abstützung der Klammer und zur Aufnahme der Klemmkräfte dienen, weil die Angriffsstelle für die Klammer von diesem Bereich weiter nach außen verlegt ist. Somit kann die Wandung die erwähnte flanschartige Fortsetzung haben, die eine gute Anlage der Rückseite der Schalhaut und eine dort vorgesehene Befestigung ermöglicht. Befestigungselemente befinden sich dann außerhalb der gegenseitigen Berührbereiche von Randstegen von Nachbarschaltafeln. Auch muß das Befestigungselement nicht in die Schmalseite der Schalhaut eingeführt werden, sondern es kann quer zur Schalhaut mit entsprechendem Querschnitt versehen angreifen. Es ergibt sich also eine verbesserte Befestigung der Schalhaut ohne Einbußen bei der möglichen Klemmkraft beim Verbinden von Randstegen von Nachbarschaltafeln.It is of considerable advantage that the angular space receiving the formwork at the edge of the edge web close to the formwork has a cross-sectionally elongated, one-piece web resting on the back of the formwork which is the continuation of the boundary wall of the cavity near the formwork and serves as a fastening flange for the formwork . The boundary wall of a cavity of the extruded profile running parallel to the formwork skin parallel to this and to the surface to be concreted does not have to be additional support of the clip and to absorb the clamping forces serve because the point of application for the clip is moved further out from this area. Thus, the wall can have the flange-like continuation mentioned, which enables the rear face of the formlining to fit well and to be fastened there. Fastening elements are then located outside the mutual contact areas of edge webs of neighboring switchboards. Also, the fastening element does not have to be inserted into the narrow side of the formlining, but rather can attack with a corresponding cross-section provided transversely to the formlining. This results in an improved fastening of the formlining without sacrificing the possible clamping force when connecting edge webs of neighboring formwork panels.

Im Bereich des freien Randes des Randsteges kann neben dem dort angeordneten Hohlraum ein Abschnitt aus Vollmaterial und eine Querschnittsverkleinerung vorgesehen sein und der freie Rand kann als Anschlag für einen Gegenanschlag an der Klammer dienen. Somit kann die Klammer insbesondere bei einer durch die Verklammerung auch quer zur Schalhaut auftretenden Kraftkomponente zum Ausrichten der beiden verbundenen Randstege dienen, die an dem Gegenanschlag an der Klammer anstoßen und somit auf gleiche und übereinstimmende Lage relativ zu der Klammer gebracht werden.In the area of the free edge of the edge web, a section made of solid material and a reduction in cross-section can be provided in addition to the cavity arranged there, and the free edge can serve as a stop for a counter-stop on the clamp. Thus, the clamp can serve in particular in the case of a force component which also occurs transversely to the formwork skin to align the two connected edge webs which abut the counter stop on the clamp and are thus brought to the same and corresponding position relative to the clamp.

Die Dicke des Randsteges kann im Bereich seiner parallelen Hohlräume beidseits der Rinne etwa gleich sein und die Dicke der Hohlräume sowie der diese begrenzenden Wandungen kann ebenfalls vorzugsweise etwa gleich sein. Es ergibt sich dann ein Randsteg von weitgehend gleichbleibender Dicke, die lediglich an der Rückseite durch die Rinne oder Nut unterbrochen ist, die der Sicke bei einem Randsteg gemäß DE-41 03 775 entspricht und auch deren Form und Wirkung haben kann. Zweckmäßig ist es dabei, wenn diese Rinne schräge Begrenzungen hat, wobei der Schrägungswinkel zum Beispiel 45° sein kann, damit sie mit einem entsprechend schräg gestalteten Vorsprung einer Klammer zusammenwirken können. Dies führt zu der schon erwähnten Ausrichtung an dem Gegenanschlag der Klammer.The thickness of the edge web can be approximately the same in the region of its parallel cavities on both sides of the channel and the thickness of the cavities and the walls delimiting them can likewise preferably be approximately the same. The result is an edge web of largely constant thickness, which is only interrupted at the rear by the groove or groove, which corresponds to the bead in an edge web according to DE-41 03 775 and can also have its shape and effect. It is expedient if this channel has inclined boundaries, the inclination angle being 45 °, for example, so that they can interact with a correspondingly slanted projection of a clip. This leads to the already mentioned alignment with the counter stop of the clip.

Auch die Breite der Hohlräume quer zur von der Schalhaut gebildeten Ebene kann etwa gleich sein. Es ergeben sich dann beidseits der Angriffs-Rinne für die Klammer etwa gleich dicke und gleich breite Hohlräume, die etwa übereinstimmende Biegefestigkeit haben. Somit kann auch die Klammerkraft gleichmäßig beidseits der Angriffsstelle der Klammer verteilt werden.The width of the cavities transverse to the plane formed by the formlining can also be approximately the same. This results in cavities of approximately the same thickness and width on both sides of the attack groove for the clamp, which have approximately the same bending strength. The clamp force can thus also be distributed evenly on both sides of the point of application of the clamp.

Die Berührfläche des Randsteges kann zwischen den beiden Rändern dieses Randsteges wenigstens eine flache Aussparung aufweisen, so daß in diesem mittleren Bereich beim Aneinanderliegen zweier Randstege ein Zwischenraum freibleibt. Unter Wirkung der Klemmkraft der Klammer wird somit eine eventuelle leichte elastische Verformung erlaubt, die zu einer entsprechend festen Zusammendrückung der eigentlichen Berührflächen und damit zu einer guten Dichtigkeit führt. Eventuelle geringfügige Verunreinigungen können von der Aussparung beziehungsweise dem Zwischenraum aufgenommen werden.The contact surface of the edge web can have at least one flat recess between the two edges of this edge web, so that a space remains free in this central region when two edge webs lie against one another. Under the action of the clamping force of the clamp, a slight elastic deformation is allowed, which leads to a correspondingly firm compression of the actual contact surfaces and thus to a good seal. Any minor contamination can be absorbed by the recess or the space.

Eine Verbindung mit einem Randsteg aus Flachmaterial aus Stahl mit eingearbeiteter Sicke gemäß DE-OS 41 03 775 wird dadurch ermöglicht, daß die rinnenförmige Nut oder dergleichen für den Angriff einer Klammer in dem Abstand zur Schalhaut beziehungsweise zum freien Rand des Randsteges angeordnet ist, in dem sich bei einem aus Flachmaterial aus Stahl geformten Randsteg eine Sicke für den Angriff der Klammer befindet, und daß die Breite des aus Flachmaterial bestehenden Randsteges insbesondere gleich der Breite des aus einem Strangpreßprofil gebildeten Randsteges ist. Somit können auch die Anschlagflächen zum gegenseitigen Ausrichten solcher aus verschiedenen Werkstoffen gebildeten Randstege dienen. Es ergibt sich also eine hohe Belastungsfähigkeit der Schaltafel bei gleichzeitig günstigem beziehungsweise niedrigem Gewicht und eine problemlose Verbindbarkeit mit den Rahmen von bekannten Schaltafeln mit aus Stahl bestehenden flachen Randstegen. In vorteilhafter Weise können dabei jeweils übereinstimmende Klammern Verwendung finden, das heißt ein Besitzer einer Schalung mit Schaltafeln aus Randstegen aus Flachmaterial aus Stahl kann als Ersatz oder zusätzlich eine Schaltafel mit dem erfindungsgemäß gestalteten Randsteg aus Strangpreßprofil erwerben und zusammen mit den anderen Schaltafeln mitbenutzen. Somit ergibt sich auch für den Besitzer einer älteren Schalung die Möglichkeit, diese nach und nach auf die neuen Schaltafeln umzustellen, ohne die noch vorhandenen älteren Schaltafeln nicht mehr verwenden zu können.A connection with an edge web made of flat material made of steel with a bead according to DE-OS 41 03 775 is made possible in that the groove-shaped groove or the like for the engagement of a clamp is arranged at a distance from the formlining or the free edge of the edge web in which there is a bead for the engagement of the clamp in a flat web made of steel, and that the width of the web made of flat material is in particular equal to the width of the web made of an extruded profile. Thus, the abutment surfaces can also serve to align such edge webs made of different materials. It This results in a high load capacity of the formwork panel with a simultaneously favorable or low weight and easy connection to the frame of known formwork panels with flat edge webs made of steel. In each case, matching brackets can advantageously be used, i.e. an owner of formwork with formwork panels made of flat webs made of steel can purchase a replacement or additionally a formwork panel with the edge web made of extruded profile designed according to the invention and use it together with the other formwork panels. This also gives the owner of an older formwork the option of gradually converting it to the new formwork panels without being able to use the older formwork panels that still exist.

Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigt in zum Teil schematisierter Darstellung:

  • Fig.1 eine teilweise im Schnitt gehaltene Seitenansicht eines Randbereiches einer Schaltafel, an deren oberem Rand der erfindungsgemäße Randsteg aus einem stranggepreßten Profil im Querschnitt dargestellt ist,
  • Fig.2 einen Querschnitt zweier aneinanderliegender erfindungsgemäßer Randstege, der Einfachheithalber ohne Schalhaut, die dabei von einer Klammer zusammengedrückt sind, welche in einem mittleren, mit einer Rinne versehenen Bereich der Randstege angreift, wo diese einen Vollquerschnitt haben sowie
  • Fig.3 eine der Fig.2 entsprechende Darstellung, wobei ein erfindungsgemäßer Randsteg aus einem Strangpreßprofil mit einem Randsteg aus flachem Stahlmaterial mit einer rinnenförmigen Sicke durch die Klammer zusammengedrückt wird, wobei wiederum der Einfachheithalber nur die Randstege und nicht die kompletten Schaltafeln dargestellt sind.
An embodiment of the invention is described below with reference to the drawing. It shows in a partially schematic representation:
  • 1 is a side view, partly in section, of an edge area of a formwork panel, on the upper edge of which the edge web according to the invention is shown in cross section from an extruded profile,
  • 2 shows a cross section of two adjoining edge webs according to the invention, for the sake of simplicity without formlining, which are pressed together by a clamp which engages in a central region of the edge webs provided with a groove, where these have a full cross section and
  • 3 shows a representation corresponding to FIG. 2, an edge web according to the invention being pressed from an extruded profile with an edge web made of flat steel material with a groove-shaped bead through the clamp, again for the sake of simplicity only the edge webs and the complete formwork panels are not shown.

Eine im ganzen mit 1 bezeichnete Schaltafel hat an ihren Rändern etwa rechtwinklig zu ihrer Schalhaut 2 abstehende, im ganzen mit 3 bezeichnete Randstege aus einem flachen Strangpreßprofil aus Aluminium, einer Aluminiumlegierung oder einem anderen Leichtmetall. Zusätzlich kann die Schalhaut durch weitere Hohlprofile 4 oder dergleichen zwischen diesen Randstegen 3 ausgesteift sein.A shuttering panel designated as a whole with 1 has at its edges approximately perpendicular to its shuttering skin 2, generally designated 3 edge webs made of a flat extruded profile made of aluminum, an aluminum alloy or another light metal. In addition, the formlining can be stiffened between these edge webs 3 by further hollow profiles 4 or the like.

An den Randstegen 3 sind rechtwinklig zur Schalhaut 2 verlaufende Anschlagflächen 5 vorgesehen, an denen in Gebrauchsstellung entsprechende Anschlagflächen 5 von Randstegen 3 von Nachbar-Schaltafeln - in der Regel unmittelbar - anliegen, wie es vor allem in Fig.2 dargestellt ist.On the edge webs 3 there are stop surfaces 5 running at right angles to the formlining, against which, in the position of use, corresponding stop surfaces 5 of edge webs 3 of neighboring formwork panels - as a rule directly - rest, as is shown above all in FIG.

An den den Anschlagflächen 5 gegenüberliegenden Rückseiten 6 greifen gemäß Fig.2 und 3 Verbindungsmittel in Form von Klammern 7 zum gegenseitigen Befestigen der aneinanderliegenden Randstege 3 an, so daß die Randstege 3 und damit die Schaltafeln 1 reibschlüssig miteinander verbunden werden. Die die Randstege 3 bildenden Strangpreßprofile haben gemäß den Ausführungsbeispielen in ihrer Längsrichtung verlaufende Kammern oder Hohlräume 8, die von Wandungen 9 allseitig umschlossen sind. Dies führt zu einer Gewichtsverminderung bei dennoch hoher Steifigkeit.2 and 3, connecting means in the form of clamps 7 for mutually fastening the adjoining edge webs 3, so that the edge webs 3 and thus the formwork panels 1 are frictionally connected to one another. According to the exemplary embodiments, the extruded profiles forming the edge webs 3 have chambers or cavities 8 running in their longitudinal direction, which are surrounded on all sides by walls 9. This leads to a reduction in weight with high rigidity.

Der eine Rand 10 des Randsteges 3, welcher sich im Bereich der Schalhaut 2 befindet, hat zum Anschließen dieser Schalhaut 2 einen Winkelraum 11, wobei der eine Winkelschenkel die Stirnfläche der Schalhaut 2 übergreift, während der andere Winkelschenkel 12 an der der Betonierfläche abgewandten Rückseite der Schalhaut 2 angreift.One edge 10 of the edge web 3, which is located in the area of the formwork skin 2, has an angular space 11 for connecting this formwork skin 2, one angle leg overlapping the end face of the formwork skin 2, while the other angle leg 12 on the back of the facing away from the concrete surface Formwork skin 2 attacks.

Der damit parallele, von der Schalhaut 2 abliegende Rand 13 des Randsteges 3 ist in Gebrauchsstellung von der Klammer 7 umgriffen, wie man es in Fig.2 und 3 erkennt.The edge 13 that is parallel to it and lies away from the formlining 2 the edge web 3 is encompassed in the use position by the clamp 7, as can be seen in FIGS. 2 and 3.

Die Angriffsstelle für die Klammer 7 ist eine an der Rückseite 6 des Randsteges 3 verlaufende Rinne 14 oder Nut, die etwa in der Mitte zwischen den Rändern 10 und 13 des Randsteges 3 angeordnet ist, so daß also die Klammer 7 nicht bis unmittelbar an die Schalhaut 2 reichen muß. Der Randsteg 3 hat im Bereich dieser Rinne 14 einen Vollquerschnitt, so daß die von der Klammer 7 ausgehenden Kräfte nicht zu einer Verformung der Hohlräume 8 führen. Diese Hohlräume 8 verlaufen beidseits der Rinne 14 im Inneren des Randsteges 3 und also auch beidseits des Bereiches mit dem Vollquerschnitt. Diese Anordnung ist deutlich in Fig.1, aber auch in Fig.2 und 3 dargestellt.The point of attack for the clamp 7 is a groove 14 or groove running on the rear side 6 of the edge web 3, which is arranged approximately in the middle between the edges 10 and 13 of the edge web 3, so that the clamp 7 is not directly up to the formwork skin 2 must suffice. The edge web 3 has a full cross section in the region of this channel 14, so that the forces emanating from the clamp 7 do not lead to a deformation of the cavities 8. These cavities 8 run on both sides of the groove 14 in the interior of the edge web 3 and thus also on both sides of the area with the full cross section. This arrangement is clearly shown in Fig.1, but also in Fig.2 and 3.

Der die Schalhaut 2 aufnehmende Winkelraum 11 an dem schalhautnahen Rand 10 des Randsteges 3 hat einen im Querschnitt verlängerten, einstückigen, an der Rückseite der Schalhaut 2 anliegenden Steg 15 oder Flansch, der die Fortsetzung der parallel zur Schalhaut 2 und der zu betonierenden Fläche verlaufenden Begrenzungswand 16 des schalhautnahen Hohlraumes 8 ist. Dieser Steg 15 kann als Befestigungsflansch für die Schalhaut 2 dienen, was durch die eine Schraube andeutende strichpunktierte Linie 17 angedeutet ist. Es ergibt sich somit genügend Platz für ein Befestigungselement nahezu beliebigen Querschnittes, so daß also eine erheblich bessere Befestigung möglich ist, als wenn diese durch den Schenkel des Winkelraumes erfolgen müßte, der die Stirnfläche 18 der Schalhaut übergreift und dort eine Dichtung 19 beaufschlagt. Darüber hinaus wird durch diesen Steg 15 der gesamte Randsteg 3 weiter ausgesteift.The angular space 11 accommodating the formlining 2 on the edge 10 of the edge web 3 close to the formlining has a one-piece web 15 or flange which is elongated in cross section and rests against the rear of the formlining 2 and which continues the boundary wall running parallel to the formlining 2 and the surface to be concreted 16 of the cavity 8 near the shell skin. This web 15 can serve as a fastening flange for the formwork skin 2, which is indicated by the dash-dotted line 17 indicating a screw. There is thus sufficient space for a fastening element of almost any cross-section, so that a considerably better fastening is possible than if this had to take place through the leg of the angular space which engages over the end face 18 of the formlining and there acts on a seal 19. In addition, the entire edge web 3 is further stiffened by this web 15.

Im Bereich des freien Randes 13 des Randsteges 3 erkennt man neben dem dort angeordneten Hohlraum 8 einen Abschnitt 20 aus Vollmaterial und eine Querschnittsverkleinerung 21, die von der Klammer 7 an einem entsprechenden Gegenanschlag 22 erfaßt werden kann, also als Anschlag beim Ausrichten zweier miteinander verbundener Randstege 3 dient, wie man es in Fig.2 erkennt. Gemäß Fig.1 und 2 weist die Anschlag- oder Berührfläche 5 des Randsteges 3 zwischen den beiden Rändern 10 und 13 eine flache Aussparung 23 auf, so daß in diesem mittleren Bereich beim Aneinanderliegen zweier Randstege 3 ein Zwischenraum freibleibt. Dieser Zwischenraum beziehungsweise die Aussparung 23 überdeckt dabei die Bereiche der Hohlräume 8, so daß die eigentliche Berührung und Kraftübertragung jeweils seitlich der Hohlräume 8 erfolgt. Entsprechend starke Druckkräfte können in diesem Bereich übertragen und aufgenommen werden.In the area of the free edge 13 of the edge web 3, in addition to the cavity 8 arranged there, a section 20 made of solid material and a cross-sectional reduction 21 can be seen the clamp 7 can be gripped at a corresponding counter stop 22, that is to say serves as a stop when aligning two interconnected edge webs 3, as can be seen in FIG. According to FIGS. 1 and 2, the abutment or contact surface 5 of the edge web 3 has a flat recess 23 between the two edges 10 and 13, so that a space remains free in this central region when two edge webs 3 lie against one another. This intermediate space or the recess 23 covers the areas of the cavities 8, so that the actual contact and power transmission takes place laterally of the cavities 8. Correspondingly strong pressure forces can be transmitted and absorbed in this area.

Dabei ist die Dicke des Randsteges 3 im Bereich seiner parallelen Hohlräume 8 beidseits der Rinne 14 etwa gleich und die Dicke der Hohlräume 8 sowie der diese begrenzenden Wandungen sind ebenfalls etwa gleich, so daß sich weitgehend übereinstimmende Maße über die gesamte Breite der Randstege 3 und damit überall gleiche Druck- und Biegefestigkeiten ergeben. Auch die Breite der Hohlräume 8 quer zur von der Schalhaut 2 gebildeten Ebene sind etwa gleich.The thickness of the edge web 3 in the region of its parallel cavities 8 on both sides of the channel 14 is approximately the same and the thickness of the cavities 8 and the walls delimiting them are also approximately the same, so that largely identical dimensions over the entire width of the edge webs 3 and thus result in the same compressive and bending strengths everywhere. The width of the cavities 8 transverse to the plane formed by the formlining 2 are approximately the same.

Die Begrenzung 24 der Rinne 14 ist gemäß Fig.1 und 2 schräg und verläuft etwa unter einem Winkel von 45° - im Querschnitt gesehen - zur Anschlagfläche 5 des Randsteges 3. Somit kann ein entsprechend gestalteter Vorsprung 25 der Klammer 7 daran angreifen und eine gewisse Kraftkomponente auch in Richtung auf den Gegenanschlag 22 an der Klammer 7 bewirken. Dabei sei erwähnt, daß die Klammer 7 die Randstege 3 nur mit ihren Vorsprüngen 25 innerhalb der Rinne 14 beaufschlagt und auch in Klemmposition gemäß Fig.2 zwischen den Klemmbacken 26 und der Rückseite der Randstege 3 ein minimaler Zwischenraum verbleiben kann. Aber selbst wenn auch hier Klemmkräfte aufgebracht und übertragen werden, können die dazwischen befindlichen Hohlräume 8 nicht eingedrückt werden, da beidseits dieses zwischen den Klemmbacken 26 befindlichen Hohlraumes 8 jeweils ein Vollquerschnitt für eine genügende Abstützung sorgt.The boundary 24 of the channel 14 is inclined according to FIGS. 1 and 2 and extends approximately at an angle of 45 ° - in cross section - to the stop surface 5 of the edge web 3. Thus, a correspondingly designed projection 25 of the clamp 7 can engage it and a certain one Force component also in the direction of the counter-stop 22 on the bracket 7. It should be mentioned that the clip 7 only applies its projections 25 within the groove 14 to the edge webs 3 and that a minimal space can also remain in the clamping position according to FIG. 2 between the clamping jaws 26 and the rear of the edge webs 3. But even if clamping forces are applied and transmitted here, too, the cavities 8 located in between cannot be pressed in because on both sides of this cavity 8 located between the clamping jaws 26, a full cross section ensures sufficient support.

An der Rinne 14 oder Nut kann eine beliebige Klammer beispielsweise gemäß DE-A-41 03 775 oder - wie im Ausführungsbeispiel dargestellt - gemäß DE-42 36 070 angreifen. Dabei ist vorgesehen, daß die rinnenförmige Nut 14 für den Angriff dieser Klammer 7 in dem Abstand zur Schalhaut 2 beziehungsweise zum freien Rand 13 des Randsteges 3 angeordnet ist, in dem sich bei einem aus Flachmaterial aus Stahl geformten Randsteg 3a gemäß Fig.3 eine Sicke 14a für den Angriff der Klammer 7 befindet. Die Breite des aus Flachmaterial bestehenden Randsteges 3a ist dabei gleich der Breite des aus einem Strangpreßprofil gebildeten Randsteges 3, so daß die beiden unterschiedlichen Randstege 3 und 3a gemäß Fig.3 mit der Klammer 7 problemlos aneinander befestigt werden können. Somit können Schaltafeln mit solchen unterschiedlichen Randstegen miteinander auf einfache Weise kombiniert werden. Es ist also gelungen, einen Randsteg aus einem stranggepreßten Leichtmetall zu schaffen, der einen guten Kraftangriff einer Klammer 7 an einer solchen Stelle erlaubt, an der die Hohlräume 8 nicht durch diese Druckkraft der Klammer 7 gefährdet werden, bei welchem außerdem eine bestmögliche Befestigung der Schalhaut 2 ermöglicht wird und der trotzdem auch noch mit einem schon bekannten und existierenden Randsteg so kombiniert werden kann, daß dieselbe Klammer 7 beide unterschiedlichen Randstege 3 und 3a aneinander festlegen kann. Somit können Schaltafeln gemäß dem Ausführungsbeispiel mit solchen Schaltafeln kombiniert werden, die Randstege 3a haben.Any clip can engage on the groove 14 or groove, for example according to DE-A-41 03 775 or - as shown in the exemplary embodiment - according to DE-42 36 070. It is provided that the groove-shaped groove 14 for the attack of this bracket 7 is arranged at a distance from the formlining 2 or from the free edge 13 of the edge web 3, in which there is a bead in the case of an edge web 3a formed from flat material made of steel according to FIG 14a for the attack of the clamp 7 is located. The width of the edge web 3a consisting of flat material is equal to the width of the edge web 3 formed from an extruded profile, so that the two different edge webs 3 and 3a according to FIG. Formwork panels with such different edge webs can thus be combined with one another in a simple manner. So it has been possible to create an edge web made of an extruded light metal, which allows a good force application of a clamp 7 at a point at which the cavities 8 are not endangered by this compressive force of the clamp 7, in which also the best possible fastening of the formwork skin 2 is made possible and which can still be combined with an already known and existing edge web so that the same clamp 7 can fix both different edge webs 3 and 3a to one another. Formwork panels according to the exemplary embodiment can thus be combined with formwork panels which have edge webs 3a.

Die Schaltafel 1 hat Randstege 3 aus einem flachen Strangpreßprofil aus Aluminium, einer Aluminiumlegierung oder einem anderen Leichtmetall und somit ein geringes Gewicht bei dennoch hoher Steifigkeit. Die Angriffsstellen für Klammern 7 zum gegenseitigen Festlegen solcher Randstege 3 benachbarter Schaltafeln 1 aneinander befinden sich mit Abstand zur Schalhaut 2 an einer Stelle, wo die Randstege 3 einen Vollquerschnitt haben und die beidseits dieser Angriffsstelle befindlichen Hohlräume 8 nicht gefährdet sind, durch die Druckkraft der Befestigungsklammer 7 verformt zu werden. Dabei ist eine Rinne 14 oder Nut als Angriff für die Klammer vorgesehen, damit auch wirklich diese Angriffsstelle benutzt wird. Somit kann dieselbe Klammer 7 verwendet werden, die auch für mit einer mittleren Sicke versehene Randstege aus Flachmaterial dienen kann, also können auch Schaltafeln mit solchen Randstegen aus unterschiedlichen Werkstoffen miteinander kombiniert werden.The formwork panel 1 has edge webs 3 made of a flat extruded profile made of aluminum, an aluminum alloy or another light metal and thus has a low weight with high rigidity. The points of attack for brackets 7 for mutually setting such edge webs 3 adjacent Formwork panels 1 are located at a distance from the formwork skin 2 at a point where the edge webs 3 have a full cross section and the cavities 8 located on both sides of this point of attack are not at risk of being deformed by the pressure force of the fastening clip 7. A groove 14 or groove is provided as an attack for the clip so that this point of attack is really used. Thus, the same clamp 7 can be used, which can also be used for edge webs provided with a central bead made of flat material, so formwork panels with such edge webs made of different materials can also be combined with one another.
