Description

Die Erfindung betrifft eine Betonschalung mit wenigstens zwei Schaltafeln, bestehend aus Haupt- und Querrahmen und einer darauf befestigten Schalplatte, und mit Verbindungselementen für benachbarte Schaltafeln, die je einen verschiebbaren Profilträger aufweisen, der über eine Keilverbindung gegen den Rahmenteil der einen Schaltafel und über eine zweite gleichartige Keilverbindung mit dem Rahmen der benachbarten Schaltafeln auf der der Schalplatte abgewandten Seite verspannbar ist, wobei die Keilverbindungen unter Zusammenziehung der Schaltafeln diese selbsttätig ausrichten. Derartige Betonschalungen haben gegenüber den Schalungen, bei denen die benachbaten Hauptrahmen durch Schraubenbolzen oder Keile verbunden sind ( vergleiche z.B. DT-AS 1 902 568, DT-OS 2 310 236, DT-OS 2 460 867), den Vorteil, daß durch den aufgekeilten Stab die Durchbiegung unter Last nur sehr gering ist, während bei den direkt verbundenen Schaltafeln bei Belastung der Verbindung senkrecht zur Schalfläche der Hauptrahmen auf Torsion beansprucht wird, was bei großer Last zu großen unzulässigen Durchbiegungen der Schalung führt. Ein Vorteil dieser direkt seitlich verbundenen Schaltafeln besteht darin, daß an der dem Schalbelag abgewandten Seite keine vorstehenden Teile vorhanden sind, die bei anderen bekannten Betonschalungen der eingangs genannten Bauart bei jeder Bewegung der Schaltafel und vor allem beim Stapeln derselben hinderlich sind, weil dadurch häufig der hochwertige kunststoffbeschichtete Schalbelag beschädigt wird.The invention relates to a concrete formwork with at least two formwork panels, consisting of a main and transverse frame and a formwork panel fastened thereon, and with connecting elements for adjacent formwork panels, each having a displaceable profile beam, which has a wedge connection against the frame part of one formwork panel and a second the same type of wedge connection can be clamped to the frame of the adjacent formwork panels on the side facing away from the formwork panel, the wedge connections aligning the formwork panels automatically. Such concrete formwork has the advantage over the formwork in which the adjacent main frame is connected by bolts or wedges (compare, for example, DT-AS 1 902 568, DT-OS 2 310 236, DT-OS 2 460 867), in that the wedge-shaped one The deflection under load is only very slight, while in the directly connected formwork panels the torsion is subjected to torsion when the connection is loaded perpendicular to the formwork surface, which leads to large inadmissible deflections of the formwork under heavy loads. An advantage of these formwork panels connected directly to the side is that there are no protruding parts on the side facing away from the formwork facing, which are a hindrance in other known concrete formworks of the type mentioned at the start of every movement of the formwork panel and especially when stacking them, because this often results in the high valuable plastic-coated formwork covering is damaged.

Eine solche Betonschalung der im Oberbegriff des Anspruchs 1 erwähnten Bauart ist durch die DE-OS 2 604 846 und die DE-GMS 7 138 715 bekannt. Bei diesem bekannten Schalungselement sind auf der der Schalplatte abgewandten Seite auf den Rahmenträgern nach hinten vorstehend U-förmige Bügel aufgeschweißt, in die der als Hohlprofil ausgebildete Profilträger einschiebbar und mittels eines Keilstückes verspannbar ist, mit dem der in den Bügel eingeführte Profilträger festklemmbar ist.Such concrete formwork of the type mentioned in the preamble of claim 1 is known from DE-OS 2 604 846 and DE-GMS 7 138 715. In this known formwork element, on the side facing away from the formwork panel, U-shaped brackets are welded to the rear on the frame girders, into which the profile girder designed as a hollow profile can be inserted and clamped by means of a wedge piece with which the profile girder inserted into the bracket can be clamped.

Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung von über die Rückseite der Schaltafeln vorstehenden Bauteilen Schaltafeln zugfest und biegefest mittels des die Tafeln selbsttätig ausrichtenden Profilträgers zu verbinden.The invention is based on the object, avoiding components protruding from the rear of the formwork panels, tensile and flexurally connected by means of the profile carrier which automatically aligns the panels.

Gelöst wird die gestellte Aufgabe durch die im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmale.The problem is solved by the features specified in the characterizing part of claim 1.

Der Keilschlitten hintergreift demgemäß mit seiner Keilanzugsfläche die Keilplatte, so daß diese in dem durch die Rahmenelemente bestimmten Raum untergebracht werden kann, ohne über die Rückseite der Rahmen vorstehen zu müssen. Vorzugsweise fluchtet die Unterseite der Keilplatte mit den unteren Begrenzungsflächen bzw. Flanschen der Quer-und Längsrahmenträger, so daß der Verbindungsprofilträger direkt mit diesen Keilplatten und den Längsträgern verspannt werden kann, die seitlich entweder unmittelbar aneinanderliegen oder auch unter Zwis-chenfügung von Ausgleichsstücken im Abstand zueinander durch die erfindungsgemäße Verbindungsvorrichtung gegeneinander verspannbar sind.The wedge sled accordingly engages behind the wedge-tightening surface of the wedge plate so that it can be accommodated in the space determined by the frame elements without having to protrude beyond the rear of the frame. Preferably, the underside of the wedge plate is aligned with the lower boundary surfaces or flanges of the transverse and longitudinal frame beams, so that the connecting profile beam can be braced directly with these wedge plates and the longitudinal beams, which either lie directly next to one another or also with spacers spaced apart can be braced against each other by the connecting device according to the invention.

Der Keilschlitten ist dabei entweder mit einem in Einschubrichtung vorkragenden Kopfteil versehen, der über die Keilplatte gleitet, welche zwischen die freien Schenkel eines im Querschnitt U-förmigen Querriegels eingeschweißt ist. Statt dessen kann die Keilanzugsfläche des Keilschlittens auch innerhalb eines den Keilschlitten bildenden geschbssenen Ringes angeordnet sein, der über eine Keilplatte geschoben wird, die am Hauptrahmenträger angeschweißt ist und frei auskragend in Richtung parallel zu den Querriegeln frei vorsteht.The wedge slide is either provided with a head part projecting in the direction of insertion, which slides over the wedge plate, which is welded between the free legs of a cross bar with a U-shaped cross section. Instead, the wedge tightening surface of the wedge slide can also be arranged within a closed ring forming the wedge slide, which is pushed over a wedge plate, which is welded to the main frame support and projects freely cantilevered in the direction parallel to the crossbars.

Die Profilträger können mit Anschlagstücken in Gestalt eines Bolzens oder einer Schweißwarze versehen sein, die das Abgleiten des Keilschlittens verhindern, so daß die Keilschlitten unverlierbar auf dem Profilträger festgelegt sind. Im allgemeinen werden jeweils zwei derartige Keilschlitten auf jedem Profilträger angeordnet, jedoch ist es auch möglich, für Sonderverbindungen drei oder mehr Keilschlitten vorzusehen, die mit entsprechenden Keilplatten von Schalungsplatten bzw. Zwischenstükken oder dergleichen zusammenwirken.The profile beams can be provided with stop pieces in the form of a bolt or a weld nipple, which prevent the wedge slide from sliding off, so that the wedge slides are captively fixed on the profile beam. In general, two such wedge slides are arranged on each profile beam, but it is also possible to provide three or more wedge slides for special connections, which cooperate with corresponding wedge plates of formwork panels or intermediate pieces or the like.

Die Keilschlitten sind auf der der Keilanzugsfläche abgewandten Seite vorzugsweise mit vorstehenden Nocken ausgestattet, die als Schlagfläche zum Eintreiben bzw. Lösen der Keilverbindung dienen.The wedge slides are preferably equipped on the side facing away from the wedge tightening surface with protruding cams which serve as a striking surface for driving in or releasing the wedge connection.

Die Schaltafeln weisen einen die Schalplatte 11 tragenden Hauptrahmen 12 und die Träger des Hauptrahmens verbindende Querriegel 14 auf. Die Querriegel 14 sind beim Ausführungsbeispiel gemäß Fig. 1 und 3 teilweise als U-Profile ausgebildet, deren freie Schenkel nachtinten weisen, während beim Ausführungsbeispiel nach Fig. 2 und 4 die Querriegel 14a ebenso wie der Hauptrahmen als Kastenprofil ausgebildet sind. Die Schaltafeln werden in der aus Fig. 3 und 4 ersichtlichen Weise (oder auch unter Zwischenfügung von Paßstücken oder Paßtafeln) so aneinandergefUgt, daß die Hauptrahmenträger 12 zweier benachbarter Schaltafeln einander berühren.The formwork panels have a main frame 12 carrying the formwork plate 11 and crossbars 14 connecting the carriers of the main frame. The crossbars 14 are partially formed in the embodiment of FIGS. 1 and 3 as U-profiles, the free legs of which have night ink, while in the embodiment of FIGS. 2 and 4 the crossbars 14a and the main frame are designed as a box profile. The formwork panels are joined together in the manner shown in FIGS. 3 and 4 (or with the interposition of fitting pieces or fitting panels) in such a way that the main frame supports 12 of two adjacent formwork panels touch one another.

Zwischen die freien Schenkel 16 der Querriegel 14 sind Keilplatten 18 eingeschweißt, die eine Keilfläche 20 besitzen und mit ihrem der Keilfläche 20 abgewandten Ende 22 dem Hauptrahmenträger 12 anliegen bzw. an diesem angeschweißt sind. Die Unterseite 24 der Keilplatten fluchtet mit der durch die Rückseite der Hauptrahmenträger 12 gebildeten Ebene. Zur Verbindung der beiden Schaltafeln sind Profilträger 26 mit Kastenprofil vorgesehen, die der Rückseite der Hauptrahmenträger 12 und der Rückseite 24 der Keilplatten 18 sowie gegebenenfalls weiteren zwischen die Schenkel des Querriegels 14 eingeschweißten Abdeckplatten 28 anliegen. Über diesen Profilträger 26 sind zwei Keilschlitten 30 geschoben, die eine der Querschnittsform des Profilträgers 26 entsprechende Öffnung aufweisen und mit frei auskragenden Kopfteilen 32 versehen sind, welche eine dem Profilträger 26 zugewandte Keilanzugsfläche 34 aufweisen, mit der sie der Keilfläche 20 der Keilplatten 18 anliegen. Die Keilschlitten weisen auf der dem Kopfteil 32 gegenüberliegenden Seite einen vorgezogenen Stützflansch 36 auf, der der Rückseite des Profilträgers 26 anliegt. Auf der gleichen Seite weist jeder Keilschlitten Nockenvorsprünge 38 auf, die zur Betätigung des Keilschlittens mit dem Hammer dienen. Durch Schlag auf die Nocken 38 kann der Keilschlitten auf der Keilplatte aufgezogen bzw. gelöst werden.Wedge plates 18 are welded between the free legs 16 of the crossbars 14, which have a wedge surface 20 and, with their end 22 facing away from the wedge surface 20, bear against the main frame support 12 or are welded to it. The underside 24 of the wedge plates is aligned with the plane formed by the back of the main frame support 12. To connect the two formwork panels, profile supports 26 with a box profile are provided, which rest against the back of the main frame supports 12 and the back 24 of the wedge plates 18 and, if appropriate, further cover plates 28 welded between the legs of the cross bar 14. Two wedge slides 30 are pushed over this profile carrier 26, which have an opening corresponding to the cross-sectional shape of the profile carrier 26 and are provided with freely projecting head parts 32 which have a wedge tightening surface 34 facing the profile carrier 26, with which they bear against the wedge surface 20 of the wedge plates 18. On the side opposite the head part 32, the wedge slides have an extended support flange 36 which bears against the rear of the profile carrier 26. On the same side, each wedge carriage has cam projections 38 which are used to actuate the wedge carriage with the hammer. By striking the cams 38, the wedge slide can be pulled up or released on the wedge plate.

Die Profilträger 26 sind mit Anschlägen in Gestalt eines das Kastenprofil durchsetzenden Stiftes 40 oder einer Schweißwarze 42 versehen, die verhindern, daß die Keilschlitten 30 über die Enden der Profilträger 26 hinweggeschoben werden und sich von diesen lösen. Auf diese Weise bleiben die Verbindungselemente als Baueinheiten mit dem Keilschlitten unverliebar verbunden.The profile carriers 26 are provided with stops in the form of a pin 40 penetrating the box profile or a weld nipple 42, which prevent the wedge slides 30 from being pushed over the ends of the profile carriers 26 and detaching from them. In this way, the connecting elements remain connected as units to the wedge carriage.

Bei dem Ausführungsbeispiel gemäß Fig. 2 und 4 sind die Keilplatten 18a neben einem Querriegel 14a mittels eines Winkelstückes 19 an einem Hauptrahmenträger 12 angeschweißt, derart, daß wiederum die Rückseite 24 bündig mit der Rückseite der Träger 12 in einer Ebene verläuft. Auf diese frei auskragenden Keilplattenstücke 18a ist der Keilschlitten 30a aufschiebbar, der im wesentlichen aus einem geschlossenen Ring besteht, welcher mit seiner balligen Keilanzugsfläche 34 auf der Keilfläche 20 der Keilplatte gleitet.In the embodiment shown in FIGS. 2 and 4, the wedge plates 18a are next to a cross bar 14a by means of an angle piece 19 on a main frame support 12 welds such that, in turn, the back 24 is flush with the back of the carrier 12 in one plane. The wedge slide 30a can be pushed onto these freely projecting wedge plate pieces 18a, which essentially consists of a closed ring which slides with its convex wedge tightening surface 34 on the wedge surface 20 of the wedge plate.

Bei dem Ausführungsbeispiel gemäß Fig. 5 ist an die Keilplatte 18a ein Stahlblechstreifen 45 angeschweißt, so daß der Keilschlitten 30a grundsätzlich in oder an der Schalungsplatte verbleiben kann. Im Montagezustand ist der Keilschlitten auf die Keilplatte aufgeschoben und im Lagerungs- oder Transportzustand entsprechend der Zeichnung in die Schalung versenkt.In the exemplary embodiment according to FIG. 5, a steel sheet strip 45 is welded to the wedge plate 18a, so that the wedge slide 30a can basically remain in or on the formwork plate. In the assembled state, the wedge carriage is pushed onto the wedge plate and, in the storage or transport state, sunk into the formwork according to the drawing.

Dies hat den Vorteil, daß der Profilträger 26 keine Anschläge 40 oder 42 erhalten muß und die Keilschlitten nach dem Lösen und Abnehmen des Profilträgers nicht herausfallen und verloren gehen.This has the advantage that the profile carrier 26 does not have to receive any stops 40 or 42 and the wedge slides do not fall out and are lost after the profile carrier has been loosened and removed.
