Description

Es ist bekannt, ein Drahtbündel aus hochwertigem Stahl, das, in einem Kanal geführt, gegen den erhärteten Beton eines Bauteils vorgespannt ist, um diesem eine Druckvorspannung zu erteilen, durch einen Stahl- oder Betonkeil zu verankern. Hiermit ist jedoch stets eine Gefährdung der vorgespannten Drähte verbunden, da sie beim Eintreiben der Keile unter Umständen beschädigt werden und reißen können. Die Erfindung ermöglicht nun die gefahrlose Verankerung der vorgespannten Drähte des Bündels, indem sie durch einen ruhenden'-Körper festgehalten werden. Zu diesem Zweck ist'zwischen dem zentrisch geführten Keil und die rohr.-förmig angeordneten Drähte ödes Bündels ein zylindrischer Hohlkörper eingeschaltet, der die Dr ähte gegen eine das Kanalende panzernde Hülse preßt.It is known, a wire bundle made of high quality steel that, in one Channel out, is biased against the hardened concrete of a component to this to apply a compressive prestressing, to anchor it with a steel or concrete wedge. However, this is always associated with a risk to the pretensioned wires because they may be damaged and tear when driving in the wedges. The invention now enables the pre-tensioned wires to be anchored safely of the bundle by being held in place by a body at rest. To this The purpose is between the centrally guided wedge and the tubular wedge Wires of the barren bundle inserted a cylindrical hollow body, which the wires presses against a sleeve armoring the end of the channel.

Die Zeichnung zeigt ein Ausführungsbeispiel der Verankerung nach der Erfindung im Längs- und Querschnitt. Mit b ist der vorzuspannende Beton des Bauteils bezeichnet. Das Ende des Kanals d, in welchem die Drähte eingezogen sind, ist durch eine Rohrhülse e gepanzert. Ferner ist in das rohrartig geformte Drahtbündel ein zylindrischer Körper c aus Beton oder einem weichen Metall eingesetzt, der Längsrillen f aufweist, um die Drähte a in gleichmäßigen Abständen zu halten. Der Körper c ist mit einer mittigen Höhlung versehen, in die nach dem Spannen der Drähte ein Stahlkeil g mit geringer Steigung eingetrieben ist, der den Hohl--körper c ausweitet und so mittelbar die Drähte gegen die Hülse e preßt. Durch diese Anpreßkraft werden die Drähte festgehalten.The drawing shows an embodiment of the anchorage according to the invention in longitudinal and cross-section. The concrete of the component to be prestressed is denoted by b. The end of the channel d, in which the wires are drawn, is armored by a tubular sleeve e. Furthermore, a cylindrical body c made of concrete or a soft metal, which has longitudinal grooves f to hold the wires a at regular intervals, is inserted into the tubular wire bundle. The body c is provided with a central cavity into which, after the wires have been tensioned, a steel wedge g with a slight pitch is driven, which expands the hollow body c and thus indirectly presses the wires against the sleeve e. The wires are held in place by this pressing force.

Man kann die Hülse am Ende des Bündelkanals auch etwas konisch ausbilden, und es ist möglich, die Verankerung als endgültige oder vorübergehende anzuwenden.You can also make the sleeve somewhat conical at the end of the bundle channel, and it is possible to apply the anchoring as permanent or temporary.
