REINFORCING MATERIAL WINDING DEVICE

摘要

PROBLEM TO BE SOLVED: To simplify a device configuration, in a reinforcing material winding device for reinforcing a steel pipe bent portion.

SOLUTION: The device includes: a plurality of guide shafts 13 which are disposed around a bent portion of a steel pipe X; a cylindrical base 32 in which the steel pipe is disposed and guided in the axial direction of the bent portion by the guide shafts; a ring-like reinforcing material holding portion 33 which is attached to the cylindrical base in such a manner that it is rotatable in the circumferential direction of the steel pipe bent portion; a guide roller 34 which is attached to the cylindrical base in such a manner that it is circled around the outside of the outer periphery of the steel pipe bent portion to guide a strip reinforcing material Y delivered from the reinforcing material holding portion toward the outer periphery of the steel pipe; a first drive mechanism which moves the cylindrical base in the axial direction of the steel pipe; and a second drive mechanism which controls the circling motion of the guide roller and the rotating motion of the reinforcing material holding portion so that the reinforcing material holding portion is rotated according to the movement of the guide roller.
