Description

Die Erfindung betrifft eine Spannvorrichtung für bandförmige Zugglieder an Tragwerken, insbesondere Betontragwerken, mit einer dauerhaft am Tragwerk befestigbaren Grundplatte und mit einer an der Grundplatte lösbar befestigbaren Spanntraverse, wobei ein mit dem bandförmigen Zugglied durch Klemmung verbindbarer 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 supporting structures, in particular concrete structures, with a permanently attachable to the structure base plate and with a releasably attachable to the base clamping spreader, a connectable to the band-shaped tension member by clamping clamping armature by itself on the tension traverse abstützender press elements for clamping the tension member is displaceable and can be supported on the tension traverse or the base plate.

Zur Erhöhung der Tragfähigkeit (Ertüchtigung) oder zur Wiederherstellung der ursprünglichen Tragfähigkeit (Sanierung) von Tragwerken aus Stahlbeton oder Spannbeton ist es beispielsweise aus JP 02266050 A 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.For example, to increase the carrying capacity (retrofitting) or restore the original carrying capacity (rehabilitation) of reinforced concrete or prestressed concrete structures JP 02266050 A known to subsequently attached to the concrete surface prestressed band-shaped tension members. As tension members, for example, lamellar plastic belts are used with embedded carbon fibers. For anchoring, for example, base plates made of steel dowelled in recesses of the concrete surface and / or secured 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.In order to apply the required preload on the band-shaped tension member before its permanent anchoring, a tensioning device is attached to one end of the tension member, which is removed again after the clamping process and the determination of the tension member on the concrete structure, for example by permanent clamping and / or gluing.

Bei bekannten Spannvorrichtungen der eingangs genannten Gattung ( DE 198 49 605 A1 oder DE 199 44 573 A1 ) wird das freie Ende des bandförmigen Zuggliedes in einen temporären Spannanker geklemmt, der mittels Pressenelementen, beispielsweise Hydraulikzylindern, von einer an der Grundplatte lösbar angebrachten Spanntraverse in seitlichen Führungen wegbewegt wird, wobei das Zugglied gespannt wird. Zur Festlegung der erreichten Spannendstellung wird der Spannanker gegen die Grundplatte verklotzt. Nach der permanenten Verankerung des Zuggliedes durch Klemmung und/oder Klebung wird die Spannvorrichtung abgenommen.In known clamping devices of the type mentioned ( DE 198 49 605 A1 or DE 199 44 573 A1 ), the free end of the band-shaped tension member is clamped in a temporary tension anchor, which is moved away by means of press elements, such as hydraulic cylinders, from a releasably attached to the base tensioner in lateral guides, wherein the tension member is tensioned. To determine the achieved clamping end position of the clamping anchor is padded against the base plate. After the permanent anchoring of the tension member by clamping and / or gluing the tensioning device is removed.

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 be maintained in a stable, applied to the concrete surface position that the lateral guides are rigidly connected to the tension traverse to accommodate the bending stresses occurring at an upward deflection of the clamping anchor. This makes a considerable design effort required, whereby the clamping device is not only difficult and unwieldy, but also increases the space requirement, so that a relatively large recess in the concrete surface must be made for the arrangement of the clamping device.

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 provide a clamping device of the type mentioned in such a way that the clamping anchor is held by the forces occurring during the clamping process stable in its desired position, without causing a bending stress of the guides.

Diese Aufgabe wird erfingdungsgemäß dadurch gelöst, dass die Spannvorrichtung einen Führungskörper aufweist, welcher in Gebrauchsstellung das zugglied zumindest nach oben gleitbar abstützt und zwischen der Spanntraverse und dem Spannanker ortsfest angeordnet ist.This object is achieved erfingdungsgemäß that the tensioning device has a guide body, which in Use position, the tension member slidably supported at least upwards and is arranged stationarily between the tensioning traverse and the clamping anchor.

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 tensioning side at a distance in front of the tension traverse arranged deflection point for the tension member. If one considers the support point of the press elements and the lateral guides, such as guide rods, on the tension traverse as a hinge, the clamping anchor can only move on a circular path whose radius is greater than the existing between the guide body and the clamping anchor distance. In order to allow this pivoting movement of the tension anchor, the tension member would have to be stretched and thus stretched even further. Therefore, the tension force exerted by the tension member on the tension anchor keeps the tension anchor in its predetermined position on the structure, for example, the concrete surface stable, without this leading to a bending stress of the guide rods. The claimed exclusively on pressure guide rods can therefore be made relatively slim, since they do not have to transmit bending moments. As a result, the clamping device as a whole is light and relatively narrow, so that their lateral space requirement is low and the size of the required recess in the structural surface, such as 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 tension member upwardly supporting guide body is arranged in the region of the tension member and thus does not protrude laterally beyond the guide rods, it does not increase the dimensions of the tensioning device.

Vorzugsweise nimmt der Führungskörper das Zugglied in einem Führungsschlitz gleitbar auf, so dass eine allseitige Führung des Zuggliedes erreicht wird.Preferably, the guide body slidably receives the tension member in a guide slot, so that an all-sided guidance of the tension member is achieved.

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 is attached to a guide beam rigidly connected to the tension traverse. As a result, the hold-down force applied to stabilize the tension member is transmitted directly to the tension traverse. A separate attachment of the guide body, which would be possible for example on the concrete structure, is dispensed with by this embodiment of the inventive concept.

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.Preferably, the guide carrier is arranged on the upper side of the tension member and has laterally beyond the tension member protruding side portions which are releasably connected to a lying under the tension member bracket. Thus, the guide slot having a guide slot body can be solved after completion of the clamping operation and the determination of the tension member in a simple manner.

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 blocking od. Like. In the plane of the tension member is done. As a result, an unstable equilibrium is achieved during clamping and in the blocked state, which only has to be secured by the guide body, without the guide body would have to absorb significant forces.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

  • Fig. 1 in einer Draufsicht ein an einem Betontragwerk angebrachtes bandförmiges Zugglied mit einer Verankerungseinrichtung an seiner Festseite und einer Spannvorrichtung an seiner Spannseite,
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1,
  • Fig. 3 einen Schnitt längs der Linie III-III in Fig. 1 und
  • Fig. 4 eine schematische Darstellung der Bewegungsverhältnisse an der Spannvorrichtung in einem Schnitt ähnlich der Fig. 2.
The invention will be explained in more detail using an exemplary embodiment, which is shown in the drawing. It shows:
  • Fig. 1 in a plan view attached to a concrete structure band-shaped tension member with an anchoring device on its fixed side and a clamping device on its clamping side,
  • Fig. 2 a section along the line II-II in Fig. 1 .
  • Fig. 3 a section along the line III-III in Fig. 1 and
  • Fig. 4 a schematic representation of the movement conditions on the clamping device in a section similar to the Fig. 2 ,

Ein bandförmiges Zugglied 1, beispielsweise eine kohlefaserverstärkte Kunststofflamelle, ist zur Anbringung an der Oberfläche eines Tragwerkes, beim dargestellten Ausführungsbeispiel eines Betontragwerks 2 bestimmt. Ebenso ist auch der Einsatz bei anderen Tragwerken, beispielsweise aus Stahl oder Holz, möglich. Vor seiner Festlegung am Betontragwerk 2 muss das Zugglied 1 vorgespannt werden.A band-shaped tension member 1, for example, a carbon fiber-reinforced plastic lamella, is intended for attachment to the surface of a supporting structure, in the illustrated embodiment of a concrete structure 2. Likewise, the use in other structures, such as steel or wood, possible. Before being fixed to the concrete structure 2, the tension member 1 must be biased.

An seinem festseitigen Ende (rechts in den Fig. 1 und 2) ist das Zugglied 1 mittels einer Klemmplatte 3, auf die mehrere Klemmbügel 4 wirken, an einer Grundplatte 5 festgelegt, die durch Dübel 6 und eine Kleberschicht 7 in einer Ausnehmung 8 des Betontragwerks 2 festgelegt ist.At its fixed end (right in the Fig. 1 and 2 ), the tension member 1 by means of a clamping plate 3, act on the multiple clamping bracket 4, fixed to a base plate 5, which is fixed by dowels 6 and an adhesive layer 7 in a recess 8 of the concrete structure 2.

In ähnlicher Weise ist am spannseitigen Ende (links in den Fig. 1 und 2) des Zuggliedes 1 eine Grundplatte 9 mittels Dübeln 10 und einer Kleberschicht 11 in einer Ausnehmung 12 des Betontragwerks 2 festgelegt. Bevor das spannseitige Ende des Zuggliedes 1 an der Grundplatte 9 ebenfalls durch eine Klemmplatte (in den Fig. 1 und 2 noch nicht dargestellt) und ggf. Klebung an der Grundplatte 9 verankert wird, muss das Zugglied 1 vorgespannt werden. Zu diesem Zweck wird eine Spannvorrichtung 13 angesetzt. Die Spannvorrichtung 13 weist eine Spanntraverse 14 auf, die mit zwei Laschen 15 versehen ist, die beiderseits des Zuggliedes 1 mittels Schrauben 16 lösbar an der Grundplatte 9 befestigt werden. Damit wird eine biegesteife, lösbare Verbindung zwischen der Spanntraverse 14 und der Grundplatte 9 hergestellt.Similarly, at the tension end (left in the Fig. 1 and 2 ) of the tension member 1, a base plate 9 by means of dowels 10 and an adhesive layer 11 defined in a recess 12 of the concrete structure 2. Before the tension-side end of the tension member 1 on the base plate 9 also by a clamping plate (in the Fig. 1 and 2 not yet shown) and, if necessary, bonding is anchored to the base plate 9, the tension member 1 must be biased. For this purpose, a clamping device 13 is attached. The tensioning device 13 has a tensioning traverse 14, which is provided with two lugs 15, which are fastened on both sides of the tension member 1 by means of screws 16 releasably secured to the base plate 9. Thus, a rigid, releasable connection between the clamping cross member 14 and the base plate 9 is produced.

An der Spanntraverse 14 stützen sich auf der der Grundplatte 9 abgekehrten Seite (in diesem Zusammenhang als "spannseitig" bezeichnet) zwei Pressenelemente 17 ab, die beim dargestellten Ausführungsbeispiel als Hydraulikzylinder ausgeführt sind. Die beiden Pressenelemente 17 liegen in der Ebene des Zuggliedes 1. Sie drücken einen Spannanker 18 von der Spanntraverse 14 weg. Der Spannanker 18 ist beiderseits an seitlichen Führungsstangen 19 geführt, die mit der Spanntraverse 14 verbunden sind. In seiner Spannendstellung ist der Spannanker 18 an den seitlichen Führungsstangen 19 festlegbar, so dass er sich dann auch nach dem Lösen der Pressenelemente 17 über die Führungsstangen 19 an der Spanntraverse 14 abstützt. Statt dessen kann auch eine andere Art der Verklotzung gewählt werden, um den Spannanker 18 abzustützen. Die Abstützung oder Verklotzung liegt bei dieser Ausführung in der Ebene des Zuggliedes 1.On the tension traverse 14 are based on the base plate 9 side facing away (referred to in this context as "tension side") from two press elements 17, which are designed in the illustrated embodiment as a hydraulic cylinder. The two press members 17 are in the plane of the tension member 1. They press a clamping armature 18 away from the tension traverse 14. The clamping anchor 18 is guided on both sides of lateral guide rods 19, which are connected to the tension traverse 14. In its Spannendstellung the clamping anchor 18 is fixed to the lateral guide rods 19, so that it is then supported even after the release of the press members 17 on the guide rods 19 on the tension traverse 14. Instead, another type of blocking can be chosen to the Support anchor 18. The support or blocking is in this embodiment in the plane of the tension member. 1

Der Spannanker 18 weist eine Unterplatte 20 auf, auf der das Zugglied 1 aufliegt. Das Zugglied 1 wird durch Klemmbügel 21, Klemmschrauben 22 und eine Klemmplatte 23 gegen die Unterplatte 20 geklemmt und auf diese Weise an dem Spannanker 18 befestigt.The clamping anchor 18 has a lower plate 20 on which the tension member 1 rests. The tension member 1 is clamped by clamping bracket 21, clamping screws 22 and a clamping plate 23 against the lower plate 20 and secured in this manner to the clamping anchor 18.

Ein Führungsträger 24 ist einstückig mit der Spanntraverse 14 ausgeführt, an dieser angeschweißt oder in anderer Weise, beispielsweise mittels Schrauben biegesteif an der Spanntraverse 14 befestigt und bildet an seinem freien Ende einen an der Oberseite des Zuggliedes 1 liegenden Führungskörper 25, der sich zwischen der Spanntraverse 14 und dem Spannanker 18 befindet und in spannseitigem Abstand zu der Spanntraverse 14 angeordnet ist.A guide support 24 is integral with the tension traverse 14, welded to this or otherwise, for example by means of screws rigidly attached to the tension traverse 14 and forms at its free end a lying at the top of the tension member 1 guide body 25 extending between the tension traverse 14 and the clamping anchor 18 and is arranged in spanseitigem distance to the tension traverse 14.

Der an der Oberseite des Zuggliedes 1 angeordnete Führungskörper 25 weist seitlich über das Zugglied 1 hinausragende Seitenabschnitte 26 auf, die mit einem unter dem Zugglied 1 liegenden Bügel 27 lösbar verbunden sind, vorzugsweise über seitliche Schrauben 28. Der Führungskörper 25 muss nicht notwendigerweise mit der Spanntraverse 14 verbunden sein: er kann auch in anderer Weise ortsfest angebracht, beispielsweise mit dem Tragwerk, hier mit dem Betontragwerk 2, verbunden sein.The arranged on the upper side of the tension member 1 guide body 25 has laterally beyond the tension member 1 projecting side portions 26 which are releasably connected to a below the tension member 1 bracket 27, preferably via lateral screws 28. The guide body 25 does not necessarily have with the tension traverse 14 may be connected: it may also be attached in a stationary manner, for example, to the supporting structure, in this case to the concrete structure 2.

Zwischen dem Führungskörper 25 und dem Bügel 27 ist ein Führungsschlitz 29 gebildet, der das Zugglied 1 gleitbar aufnimmt.Between the guide body 25 and the bracket 27, a guide slot 29 is formed, which receives the tension member 1 slidably.

Wie in Fig. 4 schematisch dargestellt ist, bildet der Führungskörper 25 eine Umlenkstelle für das Zugglied 1, die spannseitig im Abstand vor der Spanntraverse 14 liegt.As in Fig. 4 is shown schematically, the guide body 25 forms a deflection point for the tension member 1, the tension side is at a distance in front of the tension traverse 14.

Nimmt man an, dass die seitlichen Führungsstangen 19 nach Art von Pendelstützen gelenkig an der Spanntraverse 14 angebracht sind, so ergibt sich für den Spannanker 18 eine Bewegungsmöglichkeit auf einem Radius R, der gleich dem Abstand zwischen der Spanntraverse 14 und dem Spannanker 18 ist.Assuming that the lateral guide rods 19 are hingedly mounted on the tensioning beam 14 in the manner of pendulum supports, the possibility arises for the tensioning anchor 18 to move on a radius R which is equal to the distance between the tensioning beam 14 and the tensioning anchor 18.

Für das aus dem Führungskörper 25 austretende Ende des Zuggliedes ergibt sich jedoch eine theoretische Bewegungsmöglichkeit auf einem Radius, der dem Abstand zwischen dem Führungskörper 25 und dem Spannanker 18 entspricht und wesentlich kleiner ist als der Radius R. Um eine Bewegung des Spannankers 18 auf einer Kreisbahn mit dem konstruktiv vorgegebenen Bewegungsradius R zu ermöglichen, müsste daher das Zugglied 1 weiter gespannt werden. Der Spannanker 18 befindet sich somit in seiner in Fig. 4 gezeigten Lage in einer stabilen Stellung und wird in dieser stabilen Stellung gehalten, ohne dass hierbei eine Biegebeanspruchung der seitlichen Führungsstangen 19 erforderlich wäre.For the exiting from the guide body 25 end of the tension member, however, results in a theoretical movement possibility on a radius corresponding to the distance between the guide body 25 and the clamping anchor 18 and is substantially smaller than the radius R. To a movement of the clamping armature 18 on a circular path With the structurally given movement radius R to enable, therefore, the tension member 1 would have to be stretched further. The clamping anchor 18 is thus in its in Fig. 4 shown position in a stable position and is held in this stable position, without this would be a bending stress of the lateral guide rods 19 would be required.
