 According to the characteristic configuration of the present invention, the receiving portion for receiving the bolt in the inserted state is formed by the notch in the mounting portion to be mounted on the metal fitting receiving member attached to the bolt in a fitted state. Therefore, as long as the fixing nut and the metal fitting receiving member are installed on the bolt with a gap between them, the bolt can be inserted into the notch of the receiving part and can be hung even afterwards between both nuts. The mounting part of the metal fitting can be inserted.

As a result, since the hanging fitting can be mounted separately from the bolt installing work, both-hand work is reduced, and the washer and the nut of the fitting receiving member while holding the hanging fitting are held as in the conventional case. Since it is no longer a complex work of screwing, each work becomes easier.

Further, since the mounting portion that receives the bolt in the receiving portion is mounted on the metal fitting receiving member, the engaging portion that engages with the metal fitting receiving member is provided on the mounting portion. In this way, by inserting the mounting part of the hanging metal fitting between both nuts and engaging the washer of the metal fitting receiving member with the engaging part of the mounting part, the hanging metal fitting can be prevented from falling off. Can be attached.

[0012] Therefore, even if the mounting portion is not firmly fixed from above and below with the nut, the hanging metal fitting does not fall out, so that the long body can be held in the temporarily fixed state, and further, it is held. Level adjustment work for long objects can be performed by temporarily moving the nut of the metal fitting receiving member up and down without temporarily fixing the bolts as in the past. Then, after this level adjustment is completed, if the nut is tightened and the main fixing is performed, the long body can be securely held in the level adjusted state.

[0013]

[Effect of the device]

 Therefore, when mounting the long-body suspension metal fitting, it is possible to easily and temporarily fix the metal fitting receiving member by engaging the engaging part with the metal fitting receiving member with one hand, and to adjust the position in that condition. By being able to do so, it became possible to improve work efficiency and shorten the construction period while ensuring safety, and it was also possible to improve overall economic efficiency.
