However, the above-mentioned conventional pipe fixing jig has the following problems. First,
When embedding the insert in the ceiling slab in advance, the insert is fixed to the slab formwork, but the insert may come off or bend at the time of slab reinforcement or concrete pouring. In such a case, it is necessary to re-hole the ceiling slab and bury the insert. Further, since the insert is embedded in advance, the mounting position is fixed, and the mounting position cannot be changed according to the construction situation at the work site. Therefore, when changing, it is necessary to separately make a mounting hole as described above.

Further, in the above-mentioned jig, since the pipe is fixed by the metal band portion, for example, when a resin-made sheath pipe system in which irregularities are densely formed is used as the water supply pipe, the pipe cannot be sufficiently fixed. Piping may be displaced due to the water hammer phenomenon. Therefore, there is a problem that this jig cannot be directly applied to the sheath tube.

Therefore, an object of the present invention is to provide a pipe fixing jig which is easy to arrange the pipes, has good workability, and is low in cost.
