<p>PROBLEM TO BE SOLVED: To provide a pipe fixing tool which is easy to attach to pipes before pipe connection and easy to remove from the pipes after pipe connection and can therefore reduce construction period. SOLUTION: A pipe fixing tool 100 includes a pair of bases pressed against the outer peripheral surfaces of pipes 300 and a pair of rotatable handle retainers 106 inserted into shafts threaded into the bases. The pipe fixing tool further includes a fixed knob 111, threaded into each shaft and regulating the rotation of each handle retainer by pressing the base against the handle retainer and releasing the base, and a connecting handle 108 having the pair of handle retainers connected to both ends thereof. The pipe fixing tool 100 also includes a pair of plastic combination chains 113, each of which is formed in a chain wound on the outer peripheral surface of the pipe and having one end rotatably attached to the base so that it can be attached to and removed from the base, a hook 117 attached to each plastic combination chain, and a tightening knob 104 threaded into a base-mounted hinged bolt and attaching and removing the hook by pressing the hook against the base and releasing the hook.</p> |
