Low retraction anchorage is a kind of low retraction and high efficiency prestressed anchorage specially developed for short prestressed tendon anchorage due to excessive retraction during tensioning, which leads to large loss of effective permanent prestress. It can be widely used in long-span prestressed concrete continuous beams, continuous steel structures and other vertical prestressed structures of bridges, longitudinal and transverse prestressed structures of cable-stayed bridges, slope anchorage top stress structures and other short prestressed tendons
Structure.
Low retraction anchorage is composed of anchor ring, nut, clip, anchor pad and spiral reinforcement.
