Claims

[Scope of utility model registration request]

(1) An appropriate number of protrusions 3 are integrally formed on one edge of the sleeve body 1, which is made by bending a metal plate having an appropriate thickness and width into a cylindrical shape and forming a gap 2 between both edges. A sleeve for joining deformed reinforcing bars with protrusions, etc. on the outer periphery, which is provided with a recessed part 4 with an enlarged part inside at a position corresponding to these convex parts on the other end edge. .

(2) When joining the butt parts of deformed reinforcing bars with protrusions etc. on the outer periphery, insert the sleeve 1 over both parts, heat and soften the sleeve 1 from the outside with a ring burner, etc., and press it with a press or the like. By compressing from the outer periphery, the protrusions 3 are press-fitted into the corresponding recesses 4 and filled into the recesses, and at the same time, the protrusions on the outer periphery of the reinforcing bars are bitten into the inner surface of the sleeve 1 to firmly and integrally join them. A sleeve for joining deformed reinforcing bars having protrusions etc. on the outer periphery according to item 1, which is configured to obtain the above.
