[Problems to be solved by the device]

 However, the above-described conventional pipe support fitting 50 has the following problems.

First, since the base portion 51, the ring portion 55, the bolt 59, and the nut 60 are sold by mounting the bolt 59 and the nut 60 on the base portion 51 and the ring portion 55 so as not to come apart from each other, At the time of use, it is necessary to once remove the nut 60 from the bolt 59, which wastes labor and time.

Secondly, since the bolt 59 and the nut 60 are separate and independent parts, they are likely to drop during construction, and particularly when the bolt 59 and the nut 60 fall from a high place, the work is interrupted and the bolt 59 and the nut 60 are separated from each other. Since the nut 60 is pressed when the nut 60 is screwed, both hands are required, which lowers workability and work efficiency, and further impairs safety.

Thirdly, when it is attached to a vibrating portion, the bolt 59 and the nut 60 may loosen due to the vibration, which may lower the supporting strength for the pipe and may cause the pipe to drop off.

The present invention solves the problems existing in the prior art as described above, and solves the problems of wasting labor and time during use and the problems of lowering the supporting strength of pipes, as well as working. The purpose of the present invention is to provide a pipe support metal fitting that can improve safety and work efficiency, and further improve safety.
