JOINT OF PRECAST MEMBER AND PRECAST MEMBER WITH JOINT

PROBLEM TO BE SOLVED: To provide a highly reliable joint structure capable of introducing a specified initial tightening force irrespective of a manufacture error and an assembly error in a joint of a slidably connected precast member. SOLUTION: The flange part 34 of a male joint 31 projected from the joint face of one precast member is slidably inserted into the groove-like recessed part 43 of a female joint 41 buried in the other precast member. A wedge member 51 is fixed to the inner surface side of the flange part 34 of the female joint 31 with flat screws 53, and the tip bent part 52 of the wedge member 51 is fixed to the tip of the male joint 31 in an advancing direction. As the male joint 31 advances, the sloped surface of the wedge member 51 is allowed to abut on the sloped surface of a lock part 44 positioned on the joint face of the female joint 41 to introduce the tightening force while pulling the precast members to each other. When the specified tightening force is provided, the fixing of the wedge member 51 is released by the breakage of the flat screws 52 and the extending deformation of the tip bent part 52, and an initial tightening force is introduced.
