System for anchoring a tendon in a structural concrete unit

摘要

In a system for anchoring a tendon extending through a structural concrete unit, an anchoring member is located at the outside surface of the concrete unit and has a frusto-conical passage through which a tendon passes as it extends outwardly from the concrete unit. A cap fits over the outer surface of the anchoring member and forms a closure over its frusto-conical passage. The cap is shaped so that it has an inwardly projecting portion which seats against the outer ends of wedge parts securing the tendon within the passage in the anchoring member. The projection on the cap exerts a compressive force holding the wedge parts in place. Further, during construction of the concrete unit, the cap can secure the wedge parts against displacement.
