Claims

[Scope of utility model registration request]

Reverse male threaded portions 5a, which are screwed into opposite female threaded portions 3a, 4a provided on the joint tubes 3, 4, respectively, which are attached to the ends of the deformed reinforcing bars 1, 2 that are to be connected to each other;
5b on the left and right sides, and a bolt rod 5 having a torque control shaft 5c protruding from approximately the center between these male threaded portions 5a and 5b, and the torque control shaft 5c being formed in the axial direction of the inner circumferential surface. The bolt rod 5 is inserted into the bearing groove 6a.
The bolt rod 5 is rotated by the tightening ring 6, and the male threads 5a and 5b on the left and right side of the bolt rod 5 are connected to the joint tube 3. ,4
The deformed reinforcing bars 1 and 2 are connected by screwing into the female threaded portions 3a and 4a, and the torque control shaft 5c is made to break when an excessive tightening torque is applied to the tightening ring 6. In the connection fitting for deformed reinforcing bars, the outer diameter of the male threaded portions 5a, 5b of the bolt rod 5 is formed to be larger than the inner diameter of the tightening ring 6, and the tightening ring 6 is formed between these male threaded portions 5a, 5b. A connecting fitting for deformed reinforcing bars that is characterized by being movable in the axial direction.
