2. Description of the Related Art A suspension band for piping shown in FIG. 3 is widely used. The prototype of this type is disclosed in Japanese Utility Model Publication No. 29-12480. In this type of suspension band for piping, the upper end of a suspension bolt 1 is fixed to an internal thread of an insert embedded in a ceiling slab, and a turnbuckle 3 is attached to the suspension bolt 1 via a nut 2 so as to be adjustable in height. The pipe 8 is fixed by tightening each end of the suspension bands 5A and 5B connected to both legs 3A and 3B of the turnbuckle 3 by the hinge mechanism 4 with bolts 6 and nuts 7. Various types of modifications of this configuration have been proposed or implemented.

In the actual work, the work of fixing the illustrated suspension band for piping to the insert embedded in the ceiling slab is performed in advance, and then the work of actually fixing the pipe 8 is performed. When fixing the pipe 8, the nut 7 is removed once, the side of the hanging band 5B is released, the pipe 8 is passed through the inside, and then the hanging band 5B is returned to the original position and tightened by the nut 7. .

[0004]

In the piping suspension band shown in FIG. 3, the bolt holes prepared at the ends of the leg portions 3A and 3B of the turnbuckle 3 and the suspension bands 5A and 5B are so-called stupid holes. Therefore, when the nut 7 is removed at the stage of attaching the pipe 8 and the hanging band 5B is released to the state shown by the imaginary line, the bolt 6 often comes off from the intermediate fitting 3. Therefore, it is necessary to temporarily fix the nut 7 removed to release the suspension band 5B to the bolt 6 again.

Further, since the hanging bands 5A and 5B are arcuate shapes having substantially equal lengths, the hanging bands 5B easily fall off when the hanging band 5B is released as shown by a phantom line, so that the pipes can be piped by hand. It was necessary to hold 8.

An object of the present invention is to solve the above-mentioned poor workability and to clarify a piping hanging band which is easy to use and can be tightened with a bolt and a nut by one hand.
