Title: PRETENSIONED TENSION MEMBER, METHOD FOR MANUFACTURING PRETENSIONED TENSION MEMBER, CONSTRUCTION METHOD USING PRETENSIONED TENSION MEMBER, AND METHOD FOR INTRODUCING PRETENSION TO CONCRETE
Abstract:
Provided is a pretensioned tension member that uses a high-strength reinforcing bar (SD 390 or higher) as a pretensioned tension member and that is capable of easily being secured at the shortest required fixing length of the pretensioned tension member when a fixing apparatus is not used. A pretensioned tension member S according to the present invention has, on the end side of a bar-shaped base material 10 (high-strength reinforcing bar) to be tensioned, at least one projected hump 11 formed around the base material 10, the hump 11 being made of the same material as that of the base material 10 and being larger in diameter by 1.5 times than the base material 10.
