A COUPLER

摘要

A coupler for a reinforcing bar having an external thread is disclosed. The coupler includes an insert (9) having an externally threaded shank (13) and a body (3) having an internally threaded bore (5) extending through the body. The body is adapted to receive the shank of the insert via one end of the bore and to receive an end section of the reinforcing bar via an opposite end of the bore. In use, relative rotation of the insert and the body moves the ends of the shank and the reinforcing bar axially into contact and applies an axial force to the end of the reinforcing bar and thereby pre-loads the reinforcing bar.
