Definitions

  • the invention relates to a formwork panel with at its edges at right angles to the formwork edge webs made of flat material, the cross section of which extends from the scarf skin to a free edge, this cross-sectional profile being directed away from the scarf skin at least and the free edge of the free edge

  • the solution is based on the knowledge that it is sufficient to seal the adjoining edge webs - as is already known from hollow profiles - if two edge areas are available as sealing surfaces and contact surfaces, so that the edge web consisting of flat material due to the described deformations of its cross web can obtain a significantly higher rigidity compared to a consistently flat edge web.
  • this results in the additional advantage that clamps or clamps can act on the beads with their clamping jaws in the manner known for the hollow profiles forming the edge webs.
  • clamps or clamps can be attached to these, which have a stiffened cross-sectional profile, but nevertheless consist of flat material, which have the advantage of being able to be attached to practically any point in the course of the edge webs and which also have a very high clamping force and therefore good sealing enable the adjoining edge webs or the interposed Ausgeteichsteite or the like. Nevertheless, the overall weight of the formwork panel can be kept lower because the much heavier edge profiles are replaced by edge webs made of flat material that are stiffer than simple web-shaped edge webs.
  • the bead designed for the engagement of a connecting clip or clip has a distance from its outside located on the outer circumference of the formwork panel to a plane touching the two corresponding outside sides of the longitudinal edges of the web.

  • perforations penetrating the edge webs can be provided, for example, for attaching connecting bolts or the like.
  • connecting bolts either adjacent formwork panels could in turn be attached to one another or additional parts such as work platforms, supports and the like could be coupled to adjacent edge webs of adjacent formwork panels.
  • the arrangement of these coupling perforations in the area of the beads has the advantage that the clamping forces applied in the longitudinal direction of the bolts are also introduced on the beads provided for this purpose.
  • the perforations provided in the area of the beads could have a circular cross section and their diameter in particular correspond approximately to the greatest width of the bead, so that the perforation walls also penetrate the lateral boundaries of the bead.

  • transitions from the longitudinal edges to the central region of the edge web and / or the lateral boundaries of the bead can run obliquely, for example at an angle of approximately 45 degrees, with respect to the cross-sectional profile of the edge web. This not only results in good stiffening, but also permits the desired deformation of the cross section of the edge web without the risk of damage or weakening by the deformation process.
  • a formwork panel is of relatively low weight, because its edge webs can be made of flat material, but high forces can still be transmitted and clamps or clamping devices can be used to connect neighboring formwork panels, i.e. the advantages of the formwork panels with flat edge webs will be associated with the advantages that formwork panels have with edge webs formed from hollow profiles, without having to accept a significant increase in weight.
  • a formwork panel 1 has at its edges, at right angles to its formwork skin 2, peripheral edge webs 3 made of flat material, on which, in the position of use, corresponding edge webs 3 of neighboring formwork panels 1 directly or - according to FIG. 2 - directly and with the aid of connecting means, in the exemplary embodiment a clamping device 4 are connected.
  • FIG. 2 illustrates that the area 5 between the two longitudinal edges 6 and 7 of the edge web 3, which are in alignment with one another and serve as an attachment for the edge web 3 of the neighboring formwork panel 1, in the direction of these longitudinal edges 6 and 7 springs back towards the center of the formwork panel 1 and that in this recessed area 5 an oppositely shaped channel or bead 8 is arranged which is open towards the center of the formwork panel.

  • the mutually facing outer sides 8a of the beads 8 are brought closer to one another or even pressed together by the clamping force, but in the starting position, that is to say without deformation by the clamping force, they are at a distance from one of the two outer sides of the longitudinal edges 6 and. 7 of the webs 3 touching level. This ensures that the longitudinal edges 6 u. 7 of the webs 3 come into contact with one another and lie close to one another and not a premature contact of the outer sides 8a of the beads 8 such a tight connection of the longitudinal edges 6 u. 7 prevented.

  • Fig. 2 illustrates that the surfaces of the two longitudinal edges 6 and 7 of the edge web 3 located on the outside are flat, namely lie in the plane E, and are flush with one another.
  • the width of at least the longitudinal edge 6 closer to the scarf skin 2 corresponds approximately to the thickness of this skin 2, so that the recessed area 5 can begin directly on the rear side of the skin 2, but the shell skin can reach the inside of the longitudinal edge 6 except for a sealing joint can.

  • the area 5 of the edge webs 3, which springs back towards the center of the formwork panel 1 and the longitudinal edges 6 and 7, is flat except for the bead 8, so that stiffening profiles 9 arranged transversely to the edge webs 3 provide good support when they impinge on these areas 5 and find a correspondingly wide area for making a weld.
  • a clip 4 can thus be pushed over edge webs 3 lying together without requiring an excessively large opening path on their clamping jaws 10 and clamping pieces 11.
  • the edge webs 3 can be penetrated in particular in the area of their bead 8 by perforations 12, on which fastening bolts can be arranged instead of the clamp 4 or in addition thereto. While the clamp 4 allows attachment to a practically any area of the edge webs 3, fastening bolts could be provided at pre-selected locations with the aid of perforations.

Abstract

PCT No. PCT/DE92/00079 Sec. 371 Date Aug. 6, 1993 Sec. 102(e) Date Aug. 6, 1993 PCT Filed Feb. 6, 1992 PCT Pub. No. WO92/14013 PCT Pub. Date Aug. 20, 1992.A formwork panel has a board and a frame for the board. The frame is made up of strips of sheet material which extend along respective edges of the board and project from the edges at right angles to the board. Each strip has a flat longitudinal marginal portion adjacent to the board and a flat longitudinal marginal portion remote from the board. The marginal portions of a strip are located in a common plane. Each strip further has two protrusions which respectively extend from the marginal portions of the strip towards the opposite strip of the frame and define recesses opening away from the opposite strip. A protuberance is disposed between the two protrusions of a strip. Each protuberance extends from the adjoining protrusions away from the opposite strip and defines a depression opening towards the opposite strip.

Description

Die Erfindung betrifft eine Schaltafel mit an ihren Ränder rechtwinklig zur Schalhaut abstehenden Randstegen aus Flachmaterial, deren Querschnitt von der Schal haut bis zu einem freien Rand verläuft, wobei dieser Querschnittsverlauf zumindest an dem freien Rand von der Schal haut weg gerichtet ist und dieser freie Rand die größte Breite des Randsteges begrenzt, wobei an den Randstegen in Gebrauchsstellung Randstege von Nachbar-Schaltafeln mittelbar oder unmittelbar anliegen und Verbindungsmittel zum gegenseitigen Befestigen deraneinanderliegenden Randstege angreifen, wobei der Bereich zwischen den beiden miteinander fluchtenden, als Anlage für den Randsteg der Nachbar-Schaltafel dienenden Längsrändern des Randsteges gegenüber diesen Längsrändern in Richtung zu der Mitte der Schaltafel hin zurückspringt.The invention relates to a formwork panel with at its edges at right angles to the formwork edge webs made of flat material, the cross section of which extends from the scarf skin to a free edge, this cross-sectional profile being directed away from the scarf skin at least and the free edge of the free edge The greatest width of the edge web is limited, the edge webs of neighboring formwork panels directly or indirectly abutting the edge webs in the position of use and attack connecting means for mutually fastening the adjoining edge webs, the area between the two aligned longitudinal edges serving as an attachment for the edge web of the neighboring formwork panel of the edge web jumps back towards these centers in the direction of the center of the formwork panel.

Eine solche Schaltafel, bei der die- Randstege von fluchtenden und aneinandergrenzenden Schaltafeln unmittelbar aneinanderliegen, ist aus der DE-PS 21 37 505 bekannt. Als Verbindungsmittel zum gegenseitigen Befestigen der aneinanderliegenden Randstege dienen dabei schlüssellochartige Lochungen der Randstege durchsetzende Bolzen, die einen Anschlagvorsprung und einen mit Abstand dazu angeordneten Gegenanschlag haben.Such a formwork panel, in which the edge webs of aligned and adjoining formwork panels lie directly against one another, is known from DE-PS 21 37 505. Bolts which pass through keyhole-like perforations of the edge webs and which have a stop projection and a counter-stop arranged at a distance therefrom serve as connecting means for mutually fastening the edge webs lying against one another.

Aus der DE-PS 24 03 325 sind vergleichbare Schaltafeln bekannt, bei denen die Randstege benachbarter Schaltafeln mittelbar aneinanderliegen, das heißt, zwischen ihnen noch Zwischenstücke oder Abstandhalter vorgesehen sind, wobei aber auch Ausgleichselemente zwischen solchen Randstegen miteinander fluchtender Nachbar-Schaltafeln vorgesehen sein könnten.From DE-PS 24 03 325 comparable formwork panels are known in which the edge webs of adjacent formwork panels are indirectly adjacent to one another, that is, intermediate pieces or spacers are still provided between them, but compensating elements could also be provided between such adjacent webs of neighboring formwork panels.

Es ist auch aus der US-A-2870516 bekannt, daß der Bereich zwischen den beiden miteinander fluchtenden, als Anlage für den Randsteg der Nachbar-Schaltafel dienenden Längsrändern des Randsteges gegenüber diesen Längsrändern in Richtung zu der Mitte der Schaltafel hin zurückspringt, wobei dieses Dokument mehr ein Kraftschlüssiges Verbinden anstrebt, durch Zusammendrücken der gewölbten Randstege.It is also known from US-A-2870516 that the area between the two aligned longitudinal edges of the edge web, which serve as a contact for the edge web of the neighboring formwork panel, springs back towards these centers in the direction of the center of the formwork panel, this document strives for a more frictional connection, by squeezing the curved edge webs.

Die Randstege sind bei diesen vorbekannten Lösungen eben, um ein dichtes Aneinanderliegen oder Einfügen von Zwischenteilen zu ermöglichen. Dies führt jedoch dazu, daß die Steifigkeit dieser Randstege beschränkt ist, also die Schaltafeln nur eine beschränkte Belastbarkeit haben können.The edge webs are flat in these previously known solutions in order to allow a tight abutment or insertion of intermediate parts. However, this means that the rigidity of these edge webs is limited, so that the formwork panels can only have a limited load capacity.

Es ist deshalb beispielsweise aus der DE-A-27 16 864 auch schon bekannt, statt Randstegen aus Flachmaterial Hohlprofile zu verwenden, die eine größere Steifigkeit haben, aber auch zu Randstegen mit großen Querschnitten und entsprechend aufwendigen Verbindungsmitteln sowie zu erheblich höheren Gewichten der Schaltafeln führen. Bei dem profilierten Randsteg gemäß der DE-A-27 16 864 ist eine C-Form als Querschnitt gewählt, bei welcher der freie Rand des Profiles, der von der Schalhaut abliegt, gegen diese hin gerichtet ist, also nicht die größte Breite dieses Randprofiles begrenzt.It is therefore already known, for example from DE-A-27 16 864, to use hollow profiles instead of edge webs made of flat material, which have greater rigidity, but also lead to edge webs with large cross sections and correspondingly complex connecting means and to considerably higher weights of the formwork panels . In the profiled edge web according to DE-A-27 16 864, a C-shape is selected as the cross-section, in which the free edge of the profile, which lies away from the formwork skin, is directed towards the latter, so it does not limit the greatest width of this edge profile .

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Schaltafel der eingangs erwähnten Art zu schaffen, bei der die Randstege aus Flachmaterial sein können, trotzdem aber eine hohe Steifigkeit bei gleichzeitig guter Abdichtung aneinanderliegender Randstege erreicht werden kann.The invention is therefore based on the object to provide a formwork panel of the type mentioned, in which the edge webs can be made of flat material, but nevertheless a high rigidity can be achieved with good sealing of adjacent edge webs.

Die Lösung dieser Aufgabe besteht darin, daß in dem zurückspringenden Bereich wenigstens eine entgegengesetzt eingeformte, zur Schaltafelmitte offene Rinne oder Sicke angeordnet ist.The solution to this problem is that at least one oppositely shaped channel or bead, which is open to the center of the formwork panel, is arranged in the recessed area.

Die Lösung beruht also auf der Erkenntnis, daß es zum Abdichten der aneinanderliegenden Randstege - wie auch schon von Hohlprofilen bekannt - genügt, wenn jeweils zwei Randbereiche als Dichtflächen und Anlageflächen zur Verfügung stehen, so daß der aus Flachmaterial bestehende Randsteg durch die geschilderten Verformungen seines Quersteges gegenüber einem durchgängig ebenen Randsteg eine erheblich höhere Steifigkeit erhalten kann. Darüber hinaus ergibt sich dadurch der zusätzliche Vorteil, daß an den Sicken Klemmen oder Klammern mit ihren Klemmbacken in der Weise angreifen können, wie es auch bei die Randstege bildenden Hohlprofilen bekannt ist. Als Verbindungsmittel können also an diesen ein versteiftes Querschnittsprofil aufweisenden, dennoch aber aus Flachmaterial bestehenden Randstegen Klemmen oder Klammern angreifen, die den Vorteil haben, an praktisch beliebigen Stellen im Verlaufe der Randstege angesetzt werden zu können und die außerdem eine sehr hohe Klemmkraft und damit gute Abdichtung der aneinanderliegenden Randstege oder auch zwischengefügter Ausgteichsteite oder dergleichen ermöglichen. Trotzdem kann das Gesamtgewicht der Schaltafel niedriger gehalten werden, weil die wesentlich schwereren Randprofile durch gegenüber einfachen stegförmigen Randstegen steifere Randstege aus Flachmaterial ersetzt sind.The solution is based on the knowledge that it is sufficient to seal the adjoining edge webs - as is already known from hollow profiles - if two edge areas are available as sealing surfaces and contact surfaces, so that the edge web consisting of flat material due to the described deformations of its cross web can obtain a significantly higher rigidity compared to a consistently flat edge web. In addition, this results in the additional advantage that clamps or clamps can act on the beads with their clamping jaws in the manner known for the hollow profiles forming the edge webs. As a connecting means, clamps or clamps can be attached to these, which have a stiffened cross-sectional profile, but nevertheless consist of flat material, which have the advantage of being able to be attached to practically any point in the course of the edge webs and which also have a very high clamping force and therefore good sealing enable the adjoining edge webs or the interposed Ausgeteichsteite or the like. Nevertheless, the overall weight of the formwork panel can be kept lower because the much heavier edge profiles are replaced by edge webs made of flat material that are stiffer than simple web-shaped edge webs.

Besonders vorteilhaft ist es, wenn die für den Angriff einer Verbindungsklammer oder -klemme ausgebildete Sicke mit ihrer am Außenumfang der Schaltafel befindlichen Außenseite einen Abstand zu einer die beiden entsprechenden Außenseiten der Längsränder des Steges berührenden Ebene hat. Dabei ist es ausreichend, aber gleichzeitig auch vorteilhaft, wenn der Abstand der Außenseite der Sicke von der Ebene der Längsränder des Steges etwa der elastischen Verformbarkeit des Steges beim Verklemmen mit einem Nachbarsteg entspricht oder größer ist. Durch diese Maßnahmen wird also verhindert, daß beim Aneinanderliegen solcher Randstege die Außenseiten der Sicken gegeneinander abgestützt und die eigentlichen Dichtflächen nicht genügend zusammengedrückt werden. Vielmehr wird erreicht, daß die gesamte Klemm- oder Verbindungskraft auf die miteinanderfluchtenden und aneinanderliegenden Längsränder der Randstege übertragen wird. Dabei wird dieser Abstand der Außenseite der Sicke von der Ebene der Außenseiten der Längsränder um so kleiner sein, je steifer und auch dicker die Querschnitte der Randstege sind. Die Querschnittsdicke der Randstege kann zum Beispiel etwa 1/2 cm bis etwa 3/4 cm und insbesondere etwa 6 mm betragen. Dabei genügt bei einer Querschnittsdicke von etwa 6 mm schon ein Abstand der Außenseite von der Ebene der Längsränder in der Größenordnung von etwa 1/2 bis 1 mm, um einerseits den gewünschten festen Andruck der fluchtenden Längsränder und Dichtflächen der Randstege zu erreichen und andererseits die elastische Verformung unter dem Einfluß der Klemmkraft zu berücksichtigen.It is particularly advantageous if the bead designed for the engagement of a connecting clip or clip has a distance from its outside located on the outer circumference of the formwork panel to a plane touching the two corresponding outside sides of the longitudinal edges of the web. It is sufficient, but at the same time also advantageous, if the distance of the outside of the bead from the plane of the longitudinal edges of the web corresponds approximately to or is greater than the elastic deformability of the web when jammed with a neighboring web. These measures thus prevent the outer sides of the beads from being supported against one another and the actual sealing surfaces not being compressed sufficiently when such edge webs lie against one another. Rather, it is achieved that the total clamping or connecting force is transferred to the aligned and adjacent longitudinal edges of the edge webs. This distance between the outside of the bead and the plane of the outside of the longitudinal edges will be smaller the stiffer and thicker the cross sections of the edge webs. The cross-sectional thickness of the edge webs can be, for example, approximately 1/2 cm to approximately 3/4 cm and in particular approximately 6 mm. With a cross-sectional thickness of about 6 mm, a distance of the outside from the plane of the longitudinal edges in the order of about 1/2 to 1 mm is sufficient to achieve the desired firm pressure of the aligned longitudinal edges and sealing surfaces of the edge webs, on the one hand, and the elastic, on the other Consider deformation under the influence of the clamping force.

Die an der Außenseite befindlichen Flächen der beiden Längsräder des Randsteges sind zweckmäßigerweise eben und fluchten miteinander und die Breite zumindest des der Schalhaut näheren Längsrandes kann wenigstens der Dicke dieser Schalhaut etwa entsprechen, wobei jedoch zweckmäßigerweise beide Längsränder gleich breit sein können, damit sich insgesamt ein symmetrischer Querschnitt ergibt und in der Mitte der Randstege auch die Sicke angeordnet werden kann.The surfaces of the two longitudinal wheels of the edge web located on the outside are expediently flat and in alignment with one another and the width of at least the longitudinal edge closer to the formlining can at least correspond approximately to the thickness of this formlining, but expediently both longitudinal edges can be of equal width, so that overall a symmetrical Cross section results and the bead can also be arranged in the middle of the edge webs.

Der gegenüber den Längsrändern zur Mitte der Schaltafel zurückspringende Bereich der Randstege kann bis auf die Sicke eben sein. Dadurch steht dieser Bereich zur Verfügung, um weitere Aussteifungsstege zum Beispiel stumpf auftreffen zu lassen und mit den Randstegen verschweißen zu können. Außerdem könnte auf diese Weise an der Innenseite oder Innenfläche der Randstege eine Hülse für eine Spannstelle fixiert werden. Außerdem können auf diese Weise Stützen oder Konsolen gut an den Randstegen angehängt werden.The area of the edge webs that recesses towards the center of the formwork board in relation to the longitudinal edges can be flat except for the bead. This makes this area available to allow additional stiffening webs, for example, to be blunt and to be welded to the edge webs. In addition, a sleeve for a clamping point could be fixed in this way on the inside or inside surface of the edge webs. In this way, supports or brackets can also be easily attached to the edge bars.

Die in Längsrichtung des Randsteges - insbesondere in seiner Mitte - angeordnete Sicke kann über die gesamte Länge des Randsteges ununterbrochen und insbesondere mit gleichbleibendem Querschnitt verlaufen. Somit kann an praktisch jeder Stelle des Randsteges eine Klemmvorrichtung angesetzt werden. Darüber hinaus kann auf diese Weise die Herstellung der Randstege in einem kontinuierlichen Verformungsverfahren aus einem ursprünglich ebenen Flachmaterial erfolgen.The bead arranged in the longitudinal direction of the edge web - in particular in its center - can run continuously over the entire length of the edge web and in particular with a constant cross section. Thus, a clamping device can be attached to practically any point on the edge web. In addition, in this way the edge webs can be produced in a continuous deformation process from an originally flat flat material.

Im Bereich der Sicke können die Randstege durchsetzende Lochungen zum Beispiel zum Anbringen von Verbindungsbolzen oder dergleichen vorgesehen sein. Mit solchen Verbindungsbolzen könnten entweder wiederum einander benachbarte Schaltafeln aneinander befestigt werden oderes könnten Zusatzteile wie Arbeitsbühnen, Abstützungen und dergleichen mit aneinanderliegenden Randstegen benachbarter Schaltafeln gekuppeltiwerden. Die Anordnung dieser Kupplungslochungen im Bereich der Sicken hat dabei den Vorteil, daß auch die in Längsrichtung der Bolzen aufgebrachten Klemmkräfte an den dafür vorgesehenen Sicken eingeleitet werden.In the area of the bead, perforations penetrating the edge webs can be provided, for example, for attaching connecting bolts or the like. With such connecting bolts either adjacent formwork panels could in turn be attached to one another or additional parts such as work platforms, supports and the like could be coupled to adjacent edge webs of adjacent formwork panels. The arrangement of these coupling perforations in the area of the beads has the advantage that the clamping forces applied in the longitudinal direction of the bolts are also introduced on the beads provided for this purpose.

Dabei könnten die im Bereich der Sicken vorgesehenen Lochungen einen kreisrunden Querschnitt haben und ihr Durchmesser insbesondere etwa der größten Breite der Sicke entsprechen, so daß die Lochungswände auch die seitlichen Begrenzungen der Sicke durchsetzen. Somit könnte beispielsweise der Kopf einer Verbindungsschraube und auch eine mit einem Gewindebolzen zusammenwirkende Mutter jeweils an der der Schalungsmitte zugewandten Fläche des seitlich der Sicke zurückspringenden Bereiches der Randstege aufliegen.The perforations provided in the area of the beads could have a circular cross section and their diameter in particular correspond approximately to the greatest width of the bead, so that the perforation walls also penetrate the lateral boundaries of the bead. Thus, for example, the head of a connecting screw and also a nut cooperating with a threaded bolt could each rest on the surface of the area of the edge webs that recesses laterally to the bead, facing the middle of the formwork.

Die Übergänge von den Längsrändern zu dem mittleren Bereich des Randsteges und/oder die seitlichen Begrenzungen der Sicke können gegenüber dem Querschnittsverlauf des Randsteges schräg, zum Beispiel unter einem Winkel von etwa 45 Grad, verlaufen. Dies ergibt nicht nur eine gute Aussteifung, sondern erlaubt auch die gewünschte Verformung des Querschnittes des Randsteges ohne die Gefahr einer Beschädigung oder Schwächung durch den Verformungsvorgang.The transitions from the longitudinal edges to the central region of the edge web and / or the lateral boundaries of the bead can run obliquely, for example at an angle of approximately 45 degrees, with respect to the cross-sectional profile of the edge web. This not only results in good stiffening, but also permits the desired deformation of the cross section of the edge web without the risk of damage or weakening by the deformation process.

Insgesamt ergibt sich eine Schaltafel von relativ geringem Gewicht, weil ihre Randstege aus Flachmaterial bestehen können, wobei aber trotzdem hohe Kräfte übertragen und Klammern oder Klemmvorrichtungen zum Verbinden von Nachbar-Schaltafeln eingesetzt werden können, das heißt, es werden die Vorteile der Schaltafeln mit flachen Randstegen mit den Vorteilen verbunden, die Schaltafeln mit aus Hohlprofilen gebildeten Randstegen haben, ohne dabei eine erhebliche Gewichtssteigerung in Kauf nehmen zu müssen.Overall, a formwork panel is of relatively low weight, because its edge webs can be made of flat material, but high forces can still be transmitted and clamps or clamping devices can be used to connect neighboring formwork panels, i.e. the advantages of the formwork panels with flat edge webs will be associated with the advantages that formwork panels have with edge webs formed from hollow profiles, without having to accept a significant increase in weight.

Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigt:

  • Fig. 1 eine schaubildliche Darstellung einer Rückansicht einer erfindungsgemäßen Schaltafel mit an den Rändern umlaufenden profilierten Randstegen aus Flachmaterial und dazwischen angeordneten, quer verlaufenden Aussteifungsprofilen und
  • Fig. 2 einen Schnitt durch einander gegenüberliegende Randstege der Schaltafel mit einer daran befestigten Nachbar-Schaltafel, wobei die sich berührenden Randstege durch eine Klemmvorrichtung oder Klammer zusammengehalten sind.
An embodiment of the invention is described below with reference to the drawing. It shows:
  • Fig. 1 is a diagrammatic representation of a rear view of a formwork panel according to the invention with profiled edge webs running around the edges made of flat material and interposed, transverse stiffening profiles and
  • Fig. 2 shows a section through mutually opposite edge webs of the formwork panel with a neighboring formwork panel attached to it, the contacting edge webs being held together by a clamping device or clamp.

Eine Schaltafel 1 hat an ihren Rändern rechtwinklig zu ihrer Schalhaut 2 abstehende und umlaufende Randstege 3 aus Flachmaterial, an denen in Gebrauchsstellung entsprechende Randstege 3 von Nachbar-Schaltafeln 1 mittelbar oder - gemäß Fig. 2 - unmittelbar anliegen und mit Hilfe von Verbindungsmitteln, im Ausführungsbeispiel einer Klemmvorrichtung 4, verbunden sind.A formwork panel 1 has at its edges, at right angles to its formwork skin 2, peripheral edge webs 3 made of flat material, on which, in the position of use, corresponding edge webs 3 of neighboring formwork panels 1 directly or - according to FIG. 2 - directly and with the aid of connecting means, in the exemplary embodiment a clamping device 4 are connected.

Vor allem anhand der Fig.2 erkennt man dabei deutlich, daß der Querschnitt der Randstege 3 von der Schalhaut 2 bis zu einem freien Längsrand 7 verläuft, wobei dieser freie Rand 7 die größte Breite des Randsteges 3 begrenzt, also von der Schalthaut 2 weggerichtet ist.Especially with reference to Figure 2 it can be clearly seen that the cross section of the edge webs 3 from the Formwork skin 2 extends to a free longitudinal edge 7, this free edge 7 delimiting the greatest width of the edge web 3, that is to say directed away from the switching skin 2.

Die Querschnitte der Randstege 3 in Fig.2 verdeutlichen, daß der Bereich 5 zwischen den beiden miteinander fluchtenden, als Anlage für den Randsteg 3 der Nachbar-Schaltafel 1 dienenden Längsränder 6 u.7 des Randsteges 3 gegenüber diesen Längsrändern 6 u.7 in Richtung zur Mitte der Schaltafel 1 hin zurückspringt und daß in diesem zurückspringenden Bereich 5 eine entgegengesetzt eingeformte, zur Schaltafelmitte offene Rinne oder Sicke 8 angeordnet ist. Fig. 2 verdeutlicht, daß jeweils eine Sicke 8 eines Randsteges 3 mit der Sicke 8 des Randsteges 3 der Nachbar-Schaltafel 1 zusammenwirkt, wenn die Verbindungsklemme 4 an diesen Sicken 8 zur Verbindung der Schaltafeln 1 angreift. Durch die Klemmkraft werden dabei die einander zugewandten Außenseiten 8a der Sicken 8 einander angenähert oder sogar zusammengedrückt, jedoch haben sie in Ausgangsstellung, also ohne Verformung durch die Klemmkraft einen Abstand zu einer die beiden Aussenseiten der Längsränder 6 u. 7 der Stege 3 berührenden Ebene. Dadurch wird sichergestellt, daß in Gebrauchsstellung die Längsränder 6 u. 7 der Stege 3 in Berührkontakt miteinander kommen und dicht aneinanderliegen und nicht etwa eine vorzeitige Berührung der Außenseiten 8a der Sicken 8 eine solche dichte Verbindung der Längsränder 6 u. 7 verhindert. Außerdem kann über die Federkraft der Randstege 3 eine entsprechende Anpreßkraft jeweils im Bereich der Längsränder 6 u.7 erzeugt und übertragen werden.The cross sections of the edge webs 3 in FIG. 2 illustrate that the area 5 between the two longitudinal edges 6 and 7 of the edge web 3, which are in alignment with one another and serve as an attachment for the edge web 3 of the neighboring formwork panel 1, in the direction of these longitudinal edges 6 and 7 springs back towards the center of the formwork panel 1 and that in this recessed area 5 an oppositely shaped channel or bead 8 is arranged which is open towards the center of the formwork panel. Fig. 2 illustrates that a bead 8 of an edge web 3 interacts with the bead 8 of the edge web 3 of the neighboring formwork panel 1 when the connecting terminal 4 engages these beads 8 to connect the formwork panels 1. The mutually facing outer sides 8a of the beads 8 are brought closer to one another or even pressed together by the clamping force, but in the starting position, that is to say without deformation by the clamping force, they are at a distance from one of the two outer sides of the longitudinal edges 6 and. 7 of the webs 3 touching level. This ensures that the longitudinal edges 6 u. 7 of the webs 3 come into contact with one another and lie close to one another and not a premature contact of the outer sides 8a of the beads 8 such a tight connection of the longitudinal edges 6 u. 7 prevented. In addition, a corresponding contact pressure can be generated and transmitted in the area of the longitudinal edges 6 and 7 via the spring force of the edge webs 3.

Es ist also zweckmäßig, wenn der Abstand A der Außenseite 8a der Sicke 8 von der Ebene E der Längsränder 6 u. 7 des Steges 3 etwa der elastischen Verformbarkeit des Randsteges 3 beim Verklemmen mit einem Nachbarsteg entspricht oder sogar größer ist, so daß entgegen der Darstellung der Fig.2 dann die Außenseiten 8a aneinanderliegender Randstege 3 nicht in Berührkontakt gelangen.It is therefore appropriate if the distance A of the outside 8a of the bead 8 from the plane E of the longitudinal edges 6 u. 7 of the web 3 corresponds approximately to the elastic deformability of the edge web 3 when jamming with a neighboring web or is even larger, so that, contrary to the illustration in FIG. 2, the outer sides 8a of adjoining edge webs 3 do not come into contact with one another.

Fig. 2 verdeutlicht, daß die an der Außenseite befindlichen Flächen der beiden Längsränder 6 u.7 des Randsteges 3 eben sind, nämlich in der Ebene E liegen, und miteinander fluchten. Die Breite zumindest des der Schal haut 2 näheren Längsrandes 6 entspricht dabei etwa der Dicke dieser Schaihaut 2, so daß unmittelbar an der Rückseite der Schalhaut 2 der zurückspringende Bereich 5 beginnen kann, die Schalhaut aber bis auf eine Dichtfuge an die Innenseite des Längsrandes 6 heranreichen kann. Im Ausführungsbeispiel sind sogar beide Längsränder 6 u. 7 gleich breit, so daß eine im wesentlichen symmetrische Gestaltung des durch den zurückspringenden Bereich 5 einerseits und die Sicke 8 andererseits ausgesteiften Randsteges 3 entsteht, wenn - wie im Ausführungsbeispiel vorgesehen - die in Längserstreckungsrichtung des Randsteges 3 angeordnete und über die gesamte Länge des Randsteges 3 ununterbrochen und mit gleichbleibendem Querschnitt durchgehende Sicke 8 in der Mitte des Querschnittes des Randsteges 3 angeordnet ist. Der gegenüber den Längsrändern 6 u.7 zur Mitte der Schaltafel 1 zurückspringende Bereich 5 der Randstege 3 ist dabei bis auf die Sicke 8 eben, so daß quer zu den Randstegen 3 angeordnete Aussteifungsprofile 9 bei ihrem stumpfen Auftreffen auf diese Bereiche 5 eine gute Abstützung und einen entsprechend breiten Bereich zum Anbringen einer Schweißnaht vorfinden. Außerdem kann so eine Klammer 4 über zusammenliegende Randstege 3 geschoben werden, ohne einen all zu großen Öffnungsweg an ihren Klemmbacken 10 und Klemmstücken 11 zu benötigen. Die Randstege 3 können insbesondere im Bereich ihrer Sicke 8 von Lochungen 12 durchsetzt sein, an denen statt der Klammer 4 oder zusätzlich dazu Befestigungsbolzen angeordnet werden können. Während die Klammer 4 eine Befestigung an einem praktisch beliebigen Bereich der Randstege 3 erlaubt, könnten an vorgewählten Stellen mit Hilfe von Lochungen Befestigungsbolzen vorgesehen sein. Außerdem können mit solchen Befestigungsbolzen Zusatzteile wie Konsolen oder Stützträger fixiert werden.Fig. 2 illustrates that the surfaces of the two longitudinal edges 6 and 7 of the edge web 3 located on the outside are flat, namely lie in the plane E, and are flush with one another. The width of at least the longitudinal edge 6 closer to the scarf skin 2 corresponds approximately to the thickness of this skin 2, so that the recessed area 5 can begin directly on the rear side of the skin 2, but the shell skin can reach the inside of the longitudinal edge 6 except for a sealing joint can. In the embodiment, both longitudinal edges 6 u. 7 of the same width, so that an essentially symmetrical design of the edge web 3 stiffened by the recessed area 5 on the one hand and the bead 8 on the other hand arises if, as provided in the exemplary embodiment, the one arranged in the longitudinal direction of the edge web 3 and over the entire length of the edge web 3 continuous and with a constant cross-section continuous bead 8 is arranged in the middle of the cross section of the edge web 3. The area 5 of the edge webs 3, which springs back towards the center of the formwork panel 1 and the longitudinal edges 6 and 7, is flat except for the bead 8, so that stiffening profiles 9 arranged transversely to the edge webs 3 provide good support when they impinge on these areas 5 and find a correspondingly wide area for making a weld. In addition, a clip 4 can thus be pushed over edge webs 3 lying together without requiring an excessively large opening path on their clamping jaws 10 and clamping pieces 11. The edge webs 3 can be penetrated in particular in the area of their bead 8 by perforations 12, on which fastening bolts can be arranged instead of the clamp 4 or in addition thereto. While the clamp 4 allows attachment to a practically any area of the edge webs 3, fastening bolts could be provided at pre-selected locations with the aid of perforations. In addition, additional parts such as brackets or support brackets can be fixed with such fastening bolts.

Dabei ist in Fig. 2 angedeutet, daß die im Bereich der Sikken 8 vorgesehenen Lochungen 12 einen kreisrunden Querschnitt haben und ihr Durchmesser etwa der größten Breite der Sicken 8 entspricht, so daß die Lochungswände auch die seitlichen Begrenzungen 8b der Sicken 8 durchsetzen. Somit stehen die den Lochungen 12 benachbarten ebenen Zonen der zurückspringenden Bereiche 5 als Auflager für einen Kopf oder eine Mutter oder einen Vorsprung eines Befestigungsbolzens zur Verfügung.It is indicated in Fig. 2 that the holes 12 provided in the area of the sikken 8 have a circular cross section and their diameter corresponds approximately to the greatest width of the beads 8, so that the perforation walls also penetrate the lateral boundaries 8b of the beads 8. Thus, the flat zones of the recessed areas 5 adjacent to the perforations 12 are available as supports for a head or a nut or a projection of a fastening bolt.

Die Übergänge von den Längsrändern 6 u.7 zu dem mittleren Bereich 5 des Randsteges 3 und die seitlichen Begrenzungen 8b der Sicke 8 stehen gegenüber dem Querschnittsverlauf des Randsteges 3 schräg, im Ausführungsbeispiel unter einem Winkel von etwa 45 Grad. Dies bewirkt, daß die jeweils von aneinanderliegenden Längsrändern 6 ausgehenden Übergänge miteinander etwa einen rechten Winkel einschließen, was einerseits umformtechnisch und andererseits vom Einleiten der Klemmkräfte her einen guten Kompromiß bedeutet.The transitions from the longitudinal edges 6 and 7 to the central region 5 of the edge web 3 and the lateral boundaries 8b of the bead 8 are oblique with respect to the cross-sectional profile of the edge web 3, in the exemplary embodiment at an angle of approximately 45 degrees. This has the effect that the transitions originating from adjacent longitudinal edges 6 enclose each other approximately at a right angle, which on the one hand means a good compromise in terms of forming technology and on the other hand in introducing the clamping forces.

Insgesamt ergibt sich eine Schaltafel 1 hoher Steifigkeit, bei der auch die Randstege 3 trotz ihrer Fertigung aus Flachmaterial durch die Formgebung ihres Querschnittes eine hohe Steifigkeit bei relativ geringem Gewicht haben. Gleichzeitig genügt eine Klammer oder Klemme 4 von relativ geringer Spannweite, um die Randstege verbinden zu können, jedoch erlaubt dabei die die Aussteifung verbessernde Sicke 8 in vorteilhafter Weise den Angriff einer solchen Klammer 4, so daß die an sich möglichen Lochungen 5 sogar vermieden werden könnten. Auch kann mit Hilfe der Klammern 4 die gegenseitige Verbindung an praktisch beliebigen Stellen der sich berührenden Randstege 3 erfolgen. Es werden also die Vorteile des relativ geringen Gewichtes der aus Flachmaterial bestehendenOverall, there is a formwork panel 1 of high rigidity, in which the edge webs 3, despite being made from flat material, have high rigidity with a relatively low weight due to the shape of their cross section. At the same time, a clamp or clamp 4 of a relatively small span is sufficient to be able to connect the edge webs, but the stiffening bead 8 advantageously allows the attack of such a clamp 4, so that the perforations 5 which are possible per se could even be avoided . The brackets 4 can also be used to make the mutual connection at virtually any point on the contacting edge webs 3. So it will take advantage of the relatively light weight of the Flat material existing

Randstege 3 mit der Möglichkeit verbunden, an beliebigen Berührstellen Klammern ansetzen zu können, also von fest vorgegebenen Lochungsabständen unabhängig zu sein. Die Sikken 8 haben somit einerseits die Funktion der Vergrößerung der Steifigkeit der Randstege 3 und andererseits bilden sie eine günstige Angriffsstelle für die Klemme 4.Edge webs 3 are connected with the possibility of being able to attach clamps at any contact points, that is to say to be independent of predefined perforation distances. The sikken 8 thus on the one hand have the function of increasing the rigidity of the edge webs 3 and on the other hand they form a favorable point of attack for the terminal 4.

Die Schaltafel 1 hat zur Einsparung von Gewicht an ihren Rändern statt Hohlprofilen rechtwinklig zur Schalhaut 2 abstehende Randstege 3 aus Flachmaterial, die zur Vergrößerung der Steifigkeit zwischen ihren beiden miteinander fluchtenden, als Anlage für den Randsteg 3 einer Nachbar-Schaltafel 1 dienenden Längsrändern 6,7 einen zur Mitte der Schaltafel 1 zurückspringenden Bereich 5 haben, innerhalb welchem eine wiederum entgegengesetzt eingeformte, zur Schaltafelmitte offene Rinne oder Sicke 8 angeordnet ist. Es ergibt sich so ein aus Flachmaterial bestehender Randsteg 3 hoher Steifigkeit, an dessen Sicke 8 auch übliche Klammern oder Klemmen 4 angreifen können, ohne das hohe Gewicht von hohlen Randprofilen zu benötigen. Die Querschnittsdicke der Randstege 3 kann dabei zum Beispiel etwa 1/2 cm oder 0,6 cm betragen und der Abstand der Außenseite 8a der Sicke 8 von der Ebene E kann zwischen 1/2 und 1 mm, eventuell auch etwas mehr, betragen.To save weight on its edges, the formwork panel 1 has edge webs 3 made of flat material that protrude at right angles to the formwork skin 2 at its edges, which, in order to increase the rigidity between their two mutually aligned, serve as an attachment for the edge web 3 of a neighboring formwork panel 1, longitudinal edges 6, 7 have an area 5 which springs back to the center of the formwork panel 1, within which a channel or bead 8 which is in turn formed in the opposite direction and is open to the center of the formwork panel is arranged. The result is an edge web 3 of high stiffness consisting of flat material, on the bead 8 of which conventional clamps or clamps 4 can also engage without requiring the high weight of hollow edge profiles. The cross-sectional thickness of the edge webs 3 can be, for example, about 1/2 cm or 0.6 cm, and the distance between the outside 8a of the bead 8 and the plane E can be between 1/2 and 1 mm, possibly a little more.
