Abstract
For the progressive transfer of a tension or traction force from a fiber-reinforced plastic anchoring rod 10 to a threaded sleeve 20 surrounding one end of the rod, sawtooth shaped teeth are provided. The inclined flanks 6 of the teeth are increasingly longer as a function of the distance from the end 22 of the rod. The tooth length extension corresponds to the expansion of the rod under the local traction force which, because it becomes lower at each flank, decreases on a step-by-step basis. With this arrangement the rod can be stressed up to its breaking load without causing any damage to the threaded sleeve. This connection is suitable for any staying to fasten a cable to an anchoring element.
