FIXTURE FOR SCREW REINFORCING IRON BAR

摘要

PROBLEM TO BE SOLVED: To provide a fixture which facilitates movement of a screw reinforcing iron bar with respect to the axial direction and which can be fixed on the screw reinforcing iron bar in an arbitrary place as appropriate with simple operation. SOLUTION: The fixture has a sleeve-shaped body 2 having an opening 4 of which the diameter is larger than the outer diameter of the knot-forming part 73 of the screw reinforcing iron bar. Then a projection 5 projected in the inner peripheral direction is formed on the inner periphery of the opening of the body 2. By rotating the screw reinforcing iron bar 70 inserted in the opening 4 and the body 2 in the relatively opposite direction, displacement is performed between the engagement position where the projection 5 is engaged between the spiral knots 71[refer to Fig. 6 (A)] and the movable position positioned on the outer periphery of the plane parts 72, 72 [refer to Fig. 6 (B)], thus movement and fixation can be easily performed.
