PROBLEM TO BE SOLVED: To provide a jig and a construction method for it capable of ensuring matching between thread ridges of threaded reinforcement of adjacent single beams and thread grooves of a coupler and allowing prefabrication of the single beam separately.;SOLUTION: This jig is provided with a cylindrical body 2 having the thread groove matching the thread ridge of the threaded reinforcement arranged in the longitudinal direction of a PC continuous beam, a collimation member 3 arranged integrally or indirectly to the cylindrical body 2 and having a collimation point for alignment with a coupler center position, and an angle storage member 4, which can be fixed/released rotationally to/from the cylindrical body 2a. By means of the angle storage member 4, a rotation angle of a cylindrical body 2 is locked on the cylindrical body 2 when the cylindrical body 2 is meshed with the thread and the collimation point of the collimation member 3 is aligned with the coupler center position.;COPYRIGHT: (C)2003,JPO
