Abstract: A screwed connection comprises at least one rod end (10, 12) with an external thread (16) and a threaded sleeve (18) with an internal thread (20). The threaded sleeve (18) is screwed with axial play on to the rod end (10, 12). A cotter (26) is driven through a lateral opening (30) in the threaded sleeve (18) in such a way that it bears on the threaded sleeve (18) and on the end face (22, 24) of the rod end (10, 12) in order to press the external and internal threads (16, 20) axially against each other. A screwed connection of this type is particularly suitable for the production of sleeve connections and end anchorages in the case of reinforcing rods with a rolled-on thread.

Abstract: The present invention relates to an end-anchoring system for anchoring at least one bar made from a fibrous compound material and being used as a tendon in pre-stressed concrete construction, comprising an anchorage pot arranged for being fixed at a prestressed concrete component and containing a clamping body which extends over a portion of the length of the bar and encloses the latter and upon which transverse forces acting vertically to the longitudinal axis of the bar and producing a frictional connection between the rod and the clamping body and the anchorage pot, respectively, can be exerted, the clamping body being part of translating means for transforming axial forces into transverse forces and serving to transform forces acting upon the device in the longitudinal direction of the bar into proportional transverse forces providing the frictional connection between the rod and the clamping body.
