Apparatus for forming a dead-end anchorage of a post-tension system

Abstract

A method and apparatus for forming an anchorage of a post-tension system in which a tendon is positioned within a cavity of an anchor such that an end of the tendon extends outwardly of the cavity, a plurality of wedges are mechanically inserted within the cavity between the tendon and a wall of the cavity, and pressure is applied to an end of the tendon such that the tendon and the wedges are in interference-fit relationship with the cavity. A compression mechanism is used having a cylindrical member and a plunger extending in a channel of the cylindrical member. The wedges are attached to the cylindrical member and the cylindrical member is moved toward the cavity such that the wedges enter a space between the tendon and the wall of the cavity. The plunger applies a compressive force to the end of the tendon when the end of the tendon is in the channel of the cylindrical member.
