ABSTRACT:
The clamping element is supported in a positive fit on the base plate in the direction of traction of the traction element in the anchoring for pre-stressed strip-shaped traction elements on supporting structures. The traction element is received between a base plate which is fixed to the supporting structure and a clamping plate which can be clamped against the base plate and is fixed by adhesion and clamping. The clamping plate can include, on each side of the traction element, a retaining cam plate which projects in a downward manner and which engages in a retaining recess of the base plate, or can include a retaining projection which supports a stop which is connected to the base plate. The stops on the upper side of the base plate are welded push blocks which are arranged on both sides and/or in the region of the front side of the clamping plate. The clamping plate can be secured in the position thereof such that it supports the base plate in a positive fit by a positioning device which is mounted in a detachable manner in the direction of traction of the traction element. The positioning device is a threaded rod operating between the clamping element and a bridge connected to the base plate.
