Description
Die Erfindung betrifft eine Spannvorrichtung mit zwei Spannbolzen, durch die jeweils zwei parallel in Abstand zueinander liegende Schaltafeln so zusammengehalten werden, daß die insgesamt vier Schaltafeln zwei Schalungshohlräume begrenzen, die an einer Ecke in einander übergehen.The The invention relates to a clamping device with two clamping bolts, through each two parallel spaced apart formwork panels be held together so that the a total of four formwork panels limit two formwork cavities, which at a Turn the corner into each other.
Solche Spannvorrichtungen dienen beispielsweise bei Fundamentschalungen dazu, die Schaltafeln so zusammenzuhalten, daß sie dem Druck des in zähflüssigem Zustand eingefüllten Betons standhalten.Such Clamping devices are used, for example, in foundation formwork to hold the formwork panels together to withstand the pressure of the viscous state filled Withstand concrete.
Während die Schaltafeln bisher zumeist durch stabile Holztafeln gebildet werden, ist in letzter Zeit die Verwendung von Schaltafeln aus einem wesentlich leichteren Wabenmaterial aus Kunststoff vorgeschlagen worden. Da diese Schaltafeln jedoch eine geringere Biegesteifigkeit haben, besteht die Gefahr, daß insbesondere die in Bezug auf die Ecke äußeren Schaltafeln unter dem Druck des Betons an der Ecke auseinanderklaffen.While the Formwork panels have mostly been formed by sturdy wooden panels Lately, the use of formwork panels has become essential lighter honeycomb material has been proposed. There however, these formwork panels have a lower flexural rigidity, there is a risk that in particular the outer panels in relation to the corner diverge under the pressure of the concrete on the corner.
Aufgabe der Erfindung ist es, eine einfache Spannvorrichtung anzugeben, mit der sich ein solches Auseinanderklaffen der Schaltafeln an der Ecke sicher verhindern läßt.task the invention is to provide a simple clamping device, with such a divergence of the formwork panels on the Corner safely prevented.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeder Spannbolzen an seinem in Bezug auf die Ecke äußeren Ende durch eine Kreuzmuffe mit einem Zugbolzen verbunden ist, der parallel zur angrenzenden Schaltafel zum Scheitelpunkt der Ecke verläuft, und daß die beiden Zugbolzen im Bereich des Scheitelpunktes durch eine weitere Kreuzmuffe verbunden und durch an den Kreuzmuffen angreifende Muttern unter Zugspannung gehalten sind.These Task is inventively characterized solved, that everybody Clamping bolt at its in relation to the corner outer end by a cross sleeve connected to a draw bolt which is parallel to the adjacent one Panel to the vertex of the corner runs, and that the two tie bolts in the area of the vertex connected by another cross joint and held under tension by nuts acting on the cross sleeves are.
Durch die Zugbolzen wird am Scheitelpunkt der Ecke ein Zug auf die beiden dort rechtwinklig aneinandergrenzen Schaltafeln ausgeübt, durch den die Enden der Schaltafeln fest zusammengehalten werden. Die dieser Zugspannung entsprechenden Reaktionskräfte werden über die Kreuzmuffen in die Spannbolzen eingeleitet, die die Schaltafeln durchsetzen und deshalb durch diese Schaltafeln in der Zugrichtung fixiert sind.By the tie bolts will pull the two at the vertex of the corner There, at right angles to each other, formwork panels are exercised, through the ends of the formwork panels are firmly held together. The These reaction forces corresponding reaction forces are on the cross sleeves in the clamping bolt initiated, which enforce the formwork panels and therefore by this Fixing panels are fixed in the pulling direction.
Wahlweise können an der Stelle, an der sich die beiden Zugbolzen kreuzen, Abstandshalter, beispielsweise in der Form von Kanthölzern vorgesehen sein, über die sich das Ende jeder Schaltafel an dem parallel zu dieser Schaltafel verlaufenden Zugbolzen abstützt.Optional can at the point where the two tie bolts intersect, spacers, be provided, for example in the form of squared timbers, over the the end of each panel on the parallel to this board extending tensile bolt is supported.
Im folgenden wird ein Ausführungsbeispiel anhand der Zeichnung näher beschrieben.in the Following is an embodiment based closer to the drawing described.
Die Zeichnung zeigt einen schematischen horizontalen Schnitt durch eine Schalungsecke mit einer erfindungsgemäßen Spannvorrichtung.The Drawing shows a schematic horizontal section through a Formwork corner with a tensioning device according to the invention.

Wenn sich die Fundamentschalung über eine größere Höhe erstreckt, können gleichartige Spannvorrichtungen in unterschiedlichen Höhen an den Schaltafeln angebracht sein.If the foundation formwork over a greater height extends, can similar clamping devices at different heights to the Be attached.
