Description

Spanngliedstoß Die Patentanmeldung L 37763 V/37 b betrifft einen Spanngliedstoß, bei dem zwei Ankerteile durch Gewindebolzen verbunden sind, wobei die Ankerteile vor dem Betonieren des zweiten Bauabschnittes durch Anziehen der Gewindebolzen mit mindestens der Vorspannkraft der Spannglieder aneinandergepreßt werden. Tendon joint The patent application L 37763 V / 37 b relates to a tendon joint in which two anchor parts are connected by threaded bolts, the anchor parts being pressed against one another by tightening the threaded bolts with at least the prestressing force of the tendons prior to concreting the second construction section.

Bei Verwendung von Keilverankerungen kann die Anordnung so getroffen sein, daß die Enden der Spannglieder mit der an den Gewindebolzen erzeugten Kraft aneinander- sowie zusammen mit den Keilen in den Ankerkonus gepreßt werden.When using wedge anchors, the arrangement can be made in this way be that the ends of the tendons with the force generated on the threaded bolt pressed together and together with the wedges into the anchor cone.

Es hat sich nun gezeigt, daß es zum Vermeiden einer überbelastung der plattenförmigen Ankerteile zweckmäßig ist, nicht die volle Kraft der Gewindebolzen über die Keile und Drahtenden von einem Ankerteil zum anderen zu übertragen, zumal da zum sicheren Vorverkeilen der Spannglieder auch ein Teil der Bolzenkraft genügt. Es wird daher, wie in der Zeichnung beispielsweise dargestellt ist, der Rest der Bolzenkraft über ein z. B. ringförmiges Paßstück 15 übertragen, das man zwischen beide Ankerteile 3 bzw. 8 legt. Die Dicke der Paßstücke wird dabei so gewählt, daß nach einem bestimmten Einpreßweg der Keile 2 bzw. 7 eine direkte Druckübertragung zwischen den beiden Ankerteilen 3 und 8 über die Paßstücke 15 erfolgt.It has now been shown that, in order to avoid overloading the plate-shaped anchor parts, it is advisable not to transfer the full force of the threaded bolts from one anchor part to the other via the wedges and wire ends, especially since a part of the bolt force is sufficient for the secure pre-wedging of the tendons . It is therefore, as shown in the drawing, for example, the rest of the bolt force via a z. B. transferred annular fitting piece 15 , which is placed between the two anchor parts 3 and 8 , respectively. The thickness of the fitting pieces is chosen so that after a certain press-in path of the wedges 2 and 7, a direct pressure transfer between the two anchor parts 3 and 8 takes place via the fitting pieces 15.

Zur Begrenzung der Kraft, welche über die Keile übertragen wird, kann man zusätzlich zwischen die Endflächen der Keile 2 bzw. 7 und Spannglieder 1 bzw. 6 eine Platte aus verformbarem Material, z. B. eine Gummiplatte 11, einlegen, deren Festigkeit bzw. Elastizität so gewählt ist, daß das Material bei der gewünschten Teilkraft nach der Seite ausweicht.To limit the force that is transmitted via the wedges, you can also between the end surfaces of the wedges 2 and 7 and tension members 1 and 6, a plate made of deformable material, for. B. insert a rubber plate 11, the strength or elasticity of which is selected so that the material yields to the side at the desired partial force.
