Bevorzugt erfolgt die kraftschlüssige, klemmende Fixierung durch eine Klemmeinrichtung, die beispielsweise Teil der Verbindungseinrichtung sein kann, mit denen die Schalungswandungen über den dazwischen liegenden Spalt miteinander verbunden werden. Zusätzlich oder alternativ kann die kraftschlüssige, klemmende Fixierung der Fugensperre auch durch das Schalungsmaterial selbst erfolgen, das bevorzugt in Randbereichen elastisch ausgebildet, beim Einschieben der Fugensperre ausgelenkt und sich durch Federeigenschaften an die Fugensperre haltend anlegt. Die Klemm-Mittel der Verbindungseinrichtung können in unterschiedlicher Weise ausgebildet sein. Bevorzugt enthält die Verbindungseinrichtung einen Bügel mit federnden Schenkeln, wobei die Schenkel die Klemm-Mittel für die Fugensperre bilden.Preferably, the non-positive, clamping fixation by a clamping device, which may be part of the connection means, for example, with which the formwork walls are connected to each other via the gap therebetween. Additionally or alternatively, the non-positive, clamping fixation of the joint barrier can also be done by the formwork material itself, which preferably formed elastically in edge regions, deflected when inserting the joint barrier and retains holding by spring properties of the joint barrier. The clamping means of the connecting device can be designed in different ways. Preferably, the connecting device includes a bracket with resilient legs, wherein the legs form the clamping means for the joint barrier.
Zum Klemmen wird bevorzugt ein federndes Element eingesetzt, das an der Verbindungseinrichtung angeordnet ist bzw. Teil der Verbindungseinrichtung ist.For clamping, a resilient element is preferably used, which is arranged on the connecting device or is part of the connecting device.
Um eine lagegenaue Positionierung der Fugensperre zu erreichen, ist bevorzugt ein Tiefenanschlag vorgesehen, der die Einsetztiefe der Fugensperre in den Spalt begrenzt.In order to achieve a positionally accurate positioning of the joint barrier, a depth stop is preferably provided which limits the depth of insertion of the joint barrier in the gap.
Die Verbindungseinrichtung besteht aus einer Vielzahl im Abstand zueinander mit beiden Schalungswandungen verbundenen Bügeln, die über eine Verstrebung miteinander verbunden sind. Diese Verstrebung kann bevorzugt als Tiefenanschlag ausgebildet sein. Weiterhin kann durch die Verstrebung der Abstand zweier Schenkel des Bügels festgelegt werden, der dem gewünschten Klemmabstand entspricht.The connecting device consists of a plurality of spaced apart with two formwork walls connected brackets, which are connected to one another via a brace. This bracing may preferably be designed as a depth stop. Furthermore, the distance between two legs of the bracket can be determined by the brace, which corresponds to the desired clamping distance.

Die Schalungswandungen 2 können aus jedem geeigneten Schalungsmaterial bestehen, sind jedoch bevorzugt aus Metall, so dass eine ebenfalls aus Metall bestehende Verbindungseinrichtung 4 in einfacher Weise mit den Schalungswandungen 2 verschweißt werden kann. Bevorzugt ist das Material der Schalungswandungen 2 begrenzt betondurchlässig, um eine raue Anschlussfläche zu gewährleisten. Ein bevorzugtes Material für die Schalungswandungen 2 ist Streckmetall in jeder bekannten Ausführung.The
Die Verbindungseinrichtung 4 enthält im dargestellten Ausführungsbeispiel eine Mehrzahl von Bügeln 5, die mit Abstand zueinander entlang des Spaltes 3 angeordnet sind.The connecting device 4 includes in the illustrated embodiment, a plurality of brackets 5, which are arranged at a distance from each other along the
Wie auch in Verbindung mit
Der Bügel 5 weist weiterhin Befestigungseinrichtungen in Form zweiter Schenkel 5b auf, die sich im Wesentlichen parallel zur Schalungswandung 2 erstrecken und an dieser fixiert, bevorzugt angeschweißt, sind. Im dargestellten Ausführungsbeispiel erstrecken sich die zweiten Schenkel 5b über die gesamte Breite jeder Schalungswandung 2.The bracket 5 further comprises fastening means in the form of
Der Übergang zwischen den ersten und zweiten Schenkeln 5a, 5b ist mit einer Ausrundung R versehen, durch den sich die Schenkel 5a, 5b etwas von der jeweils anliegenden Schalungswandung 2 abheben.The transition between the first and
Die Schenkel 5a, 5b jeder Seite des Bügels 5 werden über einen Verbinder, z. B. einen Verbindungsbogen 5c miteinander verbunden. Der Bügel 5 wird bevorzugt mit den Schenkeln 5a, 5b und dem Verbindungsbogen 5c aus einem Metallstab gebogen.The
Die Vielzahl der Bügel 5 des Schalungselementes 1 wird über eine im Wesentlichen parallel zum Spalt 3 verlaufende Verbindungsstrebe 6 miteinander verbunden und im vorbestimmten Abstand entlang des Spaltes 3 gehalten, wobei die Verbindungsstrebe 6 als Metallstab ausgebildet und bevorzugt am Übergang zwischen den ersten Schenkeln 5a und der Verbindung 5c mit den Bügeln 5 verschweißt ist. Die Verstrebung 6 ist bevorzugt so angeordnet, dass sie die beiden Schenkel 5a in einem Abstand zueinander hält, der bevorzugt etwa gleich der Breite b des Spaltes 3 und kleiner als eine vorbestimmte Dicke d einer handelsüblichen Fugensperre 7 ist. Die Verstrebung 6 befindet sich senkrecht zur Ebene des Spaltes 3 und in einem Abstand zu diesem, der etwa der halben Breite der Fugensperre 7 (
Die Dicke d der Fugensperre 7 ist größer als die Breite b des Spaltes 3 und somit auch größer als der Abstand zwischen den beiden Schenkeln 5a jedes Bügels 5. Die Breite b und der Abstand zwischen den Schenkeln 5a bildet somit einen Klemmabstand AK, in die die Fugensperre 7 unter elastisch federnder Verdrängung der anliegenden Elemente eingedrückt wird. Der Klemmabstand AK kann so gewählt werden, dass alle oder zumindest eine Mehrzahl handelsüblicher Dicken d abgedeckt werden.The thickness d of the
Beim Einschieben der Fugensperre 7 werden Randbereiche 2a der Schalungswandungen 2, die in der Nähe oder direkt anliegend zum Spalt 3 liegen, um die Ausrundungen R gebogen und klemmen kraftschlüssig die Fugensperre 7 durch ihre Rückfederkraft. Weiterhin werden die Schenkel 5a auseinander gedrückt, wobei auch dadurch die Fugensperre 7 durch die Rückstellkraft der federnden Ausbiegung der Verbindungseinrichtung 4 und insbesondere der Schenkel 5a der Bügel 5 kraftschlüssig federnd fixiert werden kann.When inserting the
Im Gebrauch des erfindungsgemäßen Schalungselementes kann somit das Schalungselement mit den Schalungswandungen und der Verbindungseinrichtung 4 werkseitig fertiggestellt und auf die Baustelle geliefert werden. Dort wird unter elastischer Verformung die Fugensperre 7, also beispielsweise ein handelsübliches Fugenblech, in den Spalt 3 eingedrückt, wodurch zunächst die Schalungswandungen 2 um den Radius R verformt und anschließend die Schenkel 5a elastisch federnd auseinander gedrückt werden, so dass bevorzugt über die gesamte Erstreckung K der Schenkel 5a eine Klemmkraft auf die Fugensperre 7 aufgebracht werden kann. Die Verstrebung 6 wirkt dabei als Tiefenanschlag, der das Einschieben der Fugensperre 7 begrenzt.In use of the formwork element according to the invention thus the formwork element can be completed with the formwork walls and the connecting device 4 factory and delivered to the site. There, under elastic deformation, the
Das Schalungselement 10 unterscheidet sich vom Schalungselement 1 lediglich durch beidseitig angeordnete, zusätzliche Versteifungsträger 11, die die Verbindungseinrichtung 4 zusätzlich mit beiden Schalungswandungen 2 verbinden. Die Versteifungsträger 11 sind in Form herkömmlicher, flächiger Gitterträger ausgebildet und enthalten zwei parallel zueinander angeordnete Stäbe 12a und 12b, die durch zick-zack- oder bogenförmige Querstäbe 13 miteinander verbunden sind. Der erste Längsstab 12a wird beispielsweise an den Verbindern 5c der Bügel 5 und der zweite Längsstab 12b an der zugeordneten Schalungswandung 2 befestigt, bevorzugt verschweißt, so dass sich eine dachförmige Versteifung für die Verbindungseinrichtung 4 ergibt.The
In Abwandlung der geschriebenen und gezeichneten Ausführungsbeispiele kann die kraftschlüssige Klemmung auch nur entweder durch die Randbereiche der Schalungswandungen oder durch die Verbindungseinrichtung, insbesondere deren Bügel, erfolgen. Unter Umständen kann es ausreichend sein, nur einen der Randbereiche elastisch abbiegbar auszubilden. Auch müssen die Klemmabstände im Bereich der Verbindungseinrichtung und im Bereich des Spaltes nicht unbedingt gleich breit sein. Es ist weiterhin möglich, eine Klemmung außerhalb der Verbindungseinrichtung durch eine externe und/oder mit der Verbindungseinrichtung verbundene Klemmeinrichtung vorzusehen. Die Schenkel der Bügel müssen nicht unbedingt linienförmigen Kontakt über ihre gesamte Länge mit der Fugensperre aufweisen, vielmehr können sie auch schräg zur Fugensperre verlaufen und nur über einen kleinen Bereich ihrer Länge, beispielsweise durch eine Ausbiegung, in Klemmkontakt mit der Fugensperre stehen. Die Klemm-Mittel können weiterhin ein gesondertes Federelement enthalten, das nicht Teil der Verbindungseinrichtung ist.In a modification of the written and drawn embodiments, the non-positive clamping can only be done either by the edge regions of the formwork walls or by the connecting device, in particular their bracket. Under certain circumstances, it may be sufficient to form only one of the edge regions elastically bendable. Also, the clamping distances in the region of the connecting device and in the region of the gap need not necessarily be the same width. It is also possible to provide a clamping outside the connecting device by an external and / or connected to the connecting device clamping device. The legs of the bracket must not necessarily have linear contact over their entire length with the joint barrier, but they can also run obliquely to the joint barrier and only over a small portion of their length, for example, by a deflection, are in clamping contact with the joint barrier. The clamping means may further comprise a separate spring element which is not part of the connecting device.
