device for anchoring one end of at least one aeussersten cable or a rod under tension, in particular for prestressed concrete structures.

摘要

A device for anchoring one end of at least one tensioned cable or bar, in particular for a prestressed concrete structure, comprises an anchoring head having at least one conical bore through which the cable or bar is passed, and a set of conical keys located within the bore for clamping the cable or bar therein. A sleeve is attached to the cable or bar at a distance from the largest end face of the conical keys, preferably by drawing. A spacer tube is placed around the cable or bar between the conical keys and the sleeve. The spacer tube cooperates with the sleeve in order to maintain the keys within the conical bore and in order to prevent any relative displacement between the cable or bar and the conical keys in the direction of slackening of these latter.
