Claims

[Scope of utility model registration request]

(1) A reinforcing pipe for fixing formwork whose length is adjustable, comprising two pipes with equal inner and outer diameters, and an outer diameter approximately equal to the inner diameter of the pipe connecting the ends of the two pipes. The two pipes have engaging parts facing each other at their ends, which are roughly halved in the axial direction with stepped parts, and one retaining part has an engaging part facing each other in the circumferential direction at the tip. The other engaging part has a plurality of notched recesses that engage with the convex part at equal intervals, and the core body is inserted into the pipe on one side and is inserted from the tip of the retaining part. The pipe is fixed by protruding, and another pipe is inserted from the retaining part side through the protruding tip of the core body, and the lock-shaped convex part and the notch concave part are aligned so that the desired length of the reinforcing pipe is obtained. A reinforcing pipe for formwork, characterized in that the pipes are rotated and engaged with each other in the circumferential direction.

(2) The axial lengths of the engaging parts should be longer than the desired length adjustment allowance for the reinforcing pipes, and the length should be longer than the desired length adjustment allowance for the reinforcing pipes from the tip of the engaging part of the pipe to which the core was fixed. A reinforcing pipe for fixing a formwork according to claim 1 of the utility model registration, which protrudes from the outside.
