Description

Die Erfindung betrifft die Verankerung von einzelnen oder mehreren gespannten Stahldrähten in vorgespannten Stahlbetonbauteilen, von denen jeweils ein oder zwei Drähte zugleich gespannt werden. Für die Verankerung von Stahldrähten in vorgespannten Stahlbetonkonstruktionen sind mehrere Verfahren bekannt. Im praktischen Gebrauch stellen sich diese verhältnismäßig teuer bzw. gestatten nur das Spannen mehrerer Drähte gleichzeitig. Dieses wirkt sich insbesondere bei sehr kurzen Konstruktionen nachteilig aus.The invention relates to the anchoring of single or multiple tensioned steel wires in prestressed reinforced concrete components, each of which one or two wires can be tensioned at the same time. For anchoring steel wires Several methods are known in prestressed reinforced concrete structures. In practical These are relatively expensive to use or only allow tensioning multiple wires at the same time. This is particularly important in the case of very short constructions disadvantageous.

Die neue Verankerungskonstruktion besitzt diese Nachteile nicht. Durch besondere Formgebung des Verankerungskörpers tritt eine besonders günstige Spannungsverteilung im Beton ein. Die Herstellung der Verankerungskörper ist, da sie nur aus dünnen Blechen bestehen, sehr einfach und billig in bezug auf Material und Arbeitskraft.The new anchoring construction does not have these disadvantages. By The special shape of the anchoring body results in a particularly favorable stress distribution in the concrete. The manufacture of the anchoring body is because they are only made of thin Sheet metal is very simple and cheap in terms of material and labor.

Der Hauptteil der Verankerungskonstruktionen besteht aus einer oder mehreren keilförmigen, dünnen Stahlblechhülsen, die an eine dünne Stahlplatte geschweißt sind (s. Abb. i). Die vorgespannten Drähte werden in den Stahlhülsen durch festangezogene Keile an die Wandungen gepreßt (s. Abb. a). Die Wandungen sind unnachgiebig, da sie von hochwertigem Beton umgeben sind, der durch eine räumliche Stahlbewehrung nach den Regeln des Stahlbetonbaues gegen Abplatzen und Abspringen gesichert ist. Die durch die Blechhülsen eingeführte Reibungskraft wird durch die angeschweißte Blechplatte als Druckkraft in den Beton übertragen. Versuche haben gezeigt, daß die Wirkungsart in der gedachten Art eintritt.The main part of the anchoring structures consists of one or several wedge-shaped, thin sheet steel sleeves that are welded to a thin steel plate are (see Fig. i). The pre-tensioned wires are tightened in the steel sleeves Wedges pressed against the walls (see Fig. A). The walls are unyielding, there they are surrounded by high-quality concrete, which is supported by spatial steel reinforcement is secured against flaking and jumping off according to the rules of reinforced concrete construction. The frictional force introduced by the sheet metal sleeves is caused by the welded Transfer the sheet metal plate into the concrete as a compressive force. Tests have shown that the type of effect occurs in the manner imagined.
