Abstract
Description
Die Erfindung betrifft eine Spannvorrichtung für bandförmige Zugglieder an Tragwerken, insbesondere Betontragwerken, mit einer Spanntraverse, die an einer dauerhaft am Tragwerk befestigten Grundplatte lösbar befestigt ist, wobei ein mit dem bandförmigen Zugglied durch Klemmung verbundener Spannanker mittels sich an der Spanntraverse abstützender Pressenelemente zum Spannen des Zugglieds verschiebbar und an der Spanntraverse oder der Grundplatte abstützbar ist.The invention relates to a tensioning device for band-shaped tension members on structures, in particular concrete structures, with a tensioning beam, the releasably attached to a base plate permanently attached to the structure is, one with the band-shaped Tension member connected by clamping tension anchor by means of the Support crossbar Press elements for tensioning the tension member are displaceable and on the Span cross member or the base plate is supported.
Zur Erhöhung der Tragfähigkeit (Ertüchtigung) oder zur Wiederherstellung der ursprünglichen Tragfähigkeit (Sanierung) von Tragwerken aus Stahlbeton oder Spannbeton ist es bekannt, nachträglich an der Betonoberfläche vorgespannte bandförmige Zugglieder anzubringen. Als Zugglieder werden beispielsweise lamellenartige Kunststoffbänder mit eingelagerten Kohlefasern verwendet. Zur Verankerung werden beispielsweise Grundplatten aus Stahl in Ausnehmungen der Betonoberfläche angedübelt und/oder durch Klebung befestigt.To increase the load capacity (Retrofit) or to restore the original load-bearing capacity It is (renovation) of structures made of reinforced concrete or prestressed concrete known, later on the concrete surface prestressed band-shaped tension members to install. For example, slats are used as tension members Belting used with embedded carbon fibers. To be anchored For example, steel base plates are dowelled in recesses in the concrete surface and / or attached by gluing.
Um die erforderliche Vorspannung auf das bandförmige Zugglied vor dessen bleibender Verankerung aufzubringen, wird an einem Ende des Zuggliedes eine Spannvorrichtung angesetzt, die nach dem Spannvorgang und der Festlegung des Zuggliedes am Betontragwerk, beispielsweise durch permanente Klemmung und/oder Klebung, wieder abgenommen wird.To the required preload on the ribbon-shaped Applying the tension member before its permanent anchoring is on one end of the tension member a tensioner is attached, which after Tensioning process and the determination of the tension member on the concrete structure, for example by permanent clamping and / or gluing again is removed.
Bei einer bekannten Spannvorrichtung
der eingangs genannten Gattung (
Der Spannanker kann nur dadurch in einer stabilen, an der Betonoberfläche anliegenden Stellung gehalten werden, dass die seitlichen Führungen biegesteif mit der Spanntraverse verbunden werden, um die bei einem Ausweichen des Spannankers nach oben auftretenden Biegebeanspruchungen aufzunehmen. Dies macht einen erheblichen konstruktiven Aufwand erforderlich, wodurch die Spannvorrichtung nicht nur schwer und unhandlich wird, sondern sich auch der Platzbedarf erhöht, so dass für die Anordnung der Spannvorrichtung eine verhältnismäßig große Aussparung in der Betonoberfläche hergestellt werden muss.The tension anchor can only in this way held in a stable position against the concrete surface that the side guides are rigid to be connected to the tensioning crossbar in order to avoid dodging absorb the bending stresses occurring upwards. This requires considerable design effort making the tensioning device not only heavy and unwieldy, but also the space requirement increases, so that for the arrangement the clamping device has a relatively large recess in the concrete surface must be manufactured.
Aufgabe der Erfindung ist es daher, eine Spannvorrichtung der eingangs genannten Gattung so auszubilden, dass der Spannanker durch die beim Spannvorgang auftretenden Kräfte stabil in seiner gewünschten Stellung gehalten wird, ohne dass es zu einer Biegebeanspruchung der Führungen kommt.The object of the invention is therefore to design a tensioning device of the type mentioned at the beginning, that the tension anchor is stable due to the forces occurring during the tensioning process in its desired Position is held without causing bending stress the guides come.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein das Zugglied zumindest nach oben gleitbar abstützender Führungskörper zwischen der Spanntraverse und dem Spannanker ortsfest angeordnet ist.This object is achieved according to the invention solved, that a supporting member slidably at least upwards Guide body between the tensioning crossbeam and the tensioning anchor is arranged in a stationary manner.
Der Führungskörper bildet eine spannseitig im Abstand vor der Spanntraverse angeordnete Umlenkstelle für das Zugglied. Wenn man die Abstützstelle der Pressenelemente und der seitlichen Führungen, beispielsweise Führungsstangen, an der Spanntraverse als Gelenk betrachtet, so kann sich der Spannanker nur auf einer Kreisbahn bewegen, deren Radius größer ist als der zwischen dem Führungskörper und dem Spannanker bestehende Abstand. Um diese Schwenkbewegung des Spannankers zuzulassen, müsste das Zugglied gedehnt und damit noch weiter gespannt werden. Die vom Zugglied auf den Spannanker ausgeübte Spannkraft hält daher den Spannanker in seiner vorgegebenen Lage am Tragwerk, beispielsweise der Betonoberfläche stabil, ohne dass es hierbei zu einer Biegebeanspruchung der Führungsstangen kommt. Die ausschließlich auf Druck beanspruchten Führungsstangen können daher verhältnismäßig schlank ausgeführt werden, da sie keine Biegemomente übertragen müssen. Dadurch wird die Spannvorrichtung insgesamt leicht und verhältnismäßig schmal, so dass ihr seitlicher Platzbedarf gering ist und die Größe der erforderlichen Aussparung in der Tragwerksoberfläche, beispielsweise Betonoberfläche beschränkt wird.The guide body forms a tension side in the Distance in front of the tensioning crossbar for the tension member. If you have the support point the press elements and the lateral guides, for example guide rods, viewed as a joint on the tensioning crossbeam, the tensioning anchor can only move on a circular path whose radius is larger than that between the Guide body and distance between the tension anchor. To this pivoting movement of the To allow tension anchor the tension member is stretched and thus further tensioned. The The tension force exerted by the tension member on the tension anchor therefore lasts the tension anchor in its predetermined position on the structure, for example the concrete surface is stable, without causing the guide rods to bend comes. The only guide rods under pressure can therefore relatively slim accomplished because they do not have to transmit any bending moments. This will make the jig overall light and relatively narrow, so that their lateral space requirement is small and the size of the required Recess in the surface of the structure, for example concrete surface is limited.
Da der das Zugglied nach oben abstützende Führungskörper im Bereich des Zuggliedes angeordnet ist und somit seitlich nicht über die Führungsstangen hinausragt, vergrößert er die Abmessungen der Spannvorrichtung nicht.Since the guide member supporting the tension member upwards in Area of the tension member is arranged and thus not laterally over the guide rods protrudes, he enlarges the dimensions of the jig not.
vorzugsweise nimmt der Führungskörper das Zugglied in einem Führungsschlitz gleitbar auf, so dass eine allseitige Führung des Zuggliedes erreicht wird.preferably the guide body takes this Tension member in a guide slot slidably on, so that all-round guidance of the tension member is achieved becomes.
Gemäß einer bevorzugten Ausführung der Erfindung ist vorgesehen, dass der Führungskörper an einem mit der Spanntraverse biegesteif verbundenen Führungsträger angebracht ist. Dadurch wird die zur Stabilisierung des Zuggliedes aufgebrachte Niederhaltekraft unmittelbar auf die Spanntraverse übertragen. Eine gesonderte Befestigung des Führungskörpers, die beispielsweise am Betontragwerk möglich wäre, wird durch diese Ausgestaltung des Erfindungsgedankens entbehrlich.According to a preferred embodiment of the invention it is provided that the guide body on attached to the tension cross member rigidly connected guide beam is. As a result, the one applied to stabilize the tension member Hold down force directly to the tensioning beam. A separate attachment of the guide body, for example on Concrete structure possible would be this embodiment of the inventive concept can be dispensed with.
Vorzugsweise ist der Führungsträger an der Oberseite des Zuggliedes angeordnet und weist seitlich über das Zugglied hinausragende Seitenabschnitte auf, die mit einem unter dem Zugglied liegenden Bügel lösbar verbunden sind. Damit kann der einen Führungsschlitz aufweisende Führungskörper nach Beendigung des Spannvorgangs und der Festlegung des Zuggliedes in einfacher Weise gelöst werden.The guide carrier is preferably arranged on the upper side of the tension member and has been facing Lich projecting beyond the tension member side sections which are detachably connected to a bracket located under the tension member. The guide body having a guide slot can thus be released in a simple manner after the tensioning process has ended and the tension member has been fixed.
Bevorzugt ist vorgesehen, dass die Pressenelemente in der Ebene des Zuggliedes liegen und dass die Abstützung des Spannankers durch Verklotzung od. dgl. in der Ebene des Zuggliedes erfolgt. Dadurch wird beim Spannen und im verklotzten Zustand ein labiles Gleichgewicht erreicht, das durch den Führungskörper nur gesichert werden muss, ohne dass der Führungskörper wesentliche Kräfte aufnehmen müsste.It is preferably provided that the Press elements are in the plane of the tension member and that the support of the tension anchor by padding or the like. in the plane of the tension member he follows. As a result, when tensioning and in the blocked state unstable equilibrium achieved, which only has to be secured by the guide body without that the leader body essential Absorb forces would.
