Cable end anchorage with overload protection

摘要

A cable end anchorage for fastening at least one cable at a supporting structure includes at least one first connecting element for connection with the supporting structure, at least one second connecting element for connection with the cable and at least one coupling element for connection of the two connecting elements in a force-transmitting manner. In the region of the coupling element, an overload device designed as a predetermined breaking point of the coupling element is provided for unfastening the connection between the two connecting elements when a critical load has been exceeded. A stop device is provided for limiting the relative motion of the connecting elements after unfastening of the connection when a critical load has been exceeded. The cable end anchorage features a transverse plate that is connected with the coupling element in a force-transmitting manner and at least one tension rod that penetrates the transverse plate in a recess with an at least slightly radial clearance, wherein one end of the tension rod is connected with one of the two connecting elements in a force-transmitting manner on one side of the transverse plate, and a terminal plate is provided at the opposite end of the tension rod on the other side of the transverse plate, the terminal plate serving as a stop on the transverse plate when a critical load has been exceeded.

1. A cable end anchorage for fastening at least one cable at a supporting structure, said anchorage comprising:
at least one first connecting element for connection with the supporting structure; at least one second connecting element for connection with the cable; at least one coupling element connecting the first and second connecting elements in a force-transmitting manner, said at least one coupling element including a predetermined breaking point, said predetermined breaking point unfastening the connection between the two connecting elements when a critical load has been exceeded; a transverse plate connected with the at least one coupling element in a force-transmitting manner, said transverse plate being a stop device limiting relative motion of the connecting elements after unfastening of the connection when a critical load has been exceeded; at least one tension rod penetrating the transverse plate, wherein one end of the at least one tension rod is connected with one of the two connecting elements in a force-transmitting manner on one side of the transverse plate; a terminal plate provided at the opposite end of the tension rod on an opposing side of the transverse plate, the terminal plate serving as a stop on the transverse plate when a critical load has been exceeded, said at least one coupling element extending through said terminal plate with a radial clearance; and at least one of a spring and a damper device located between the terminal plate and the transverse plate and absorbing the loads acting upon the stop device after unfastening of the connection when the critical load has been exceeded.
