A plurality of hangers 12 and 12 are engaged with each of the field receivers 16 and 16, and a suspension bolt 14 suspended from above the building is screwed to each of the hangers 12. Also,
A plurality of fields, such as M-bars, are placed between each field receiver 16 and 16.
50 are passed, and each field edge 50 is engaged with the field edge receiver 16 via a clip 52. The ceiling is formed by attaching a ceiling panel to the surface (lower surface) of the field edge 50.

When hanging a hanging bolt for hanging a lighting fixture or the like from the ceiling base set 54 having such a structure, the following construction method has been conventionally used. (1) A panel is attached to the field edge 50 to complete the ceiling, the hanging bolt is positioned to be drawn out, and then a hole for inserting a bolt is formed in the ceiling panel. (2) Enter the back of the ceiling and pass the square pipe 56 over the plurality of field rim receivers 16 and 16, as shown in FIGS. (3) Insert the tip of the hanging bolt 40 into the room through the hole 60 of the ceiling panel 58, insert the rear end into the hole 62 formed in the square pipe 56, and tighten the nut 64 to fix it.

[004]

However, in the above-mentioned construction method, since the square pipe 56 to which the suspension bolt 40 is fixed is simply placed on the field edge receiver 16 engaged with the hanger 12, the suspension bolt is suspended. A heavy load on 40
There was a problem that 16 was tilted in the hook of hanger 12 and could not receive the load vertically.

In a situation where the ceiling is narrow and people cannot enter, the rear end of the hanging bolt 40 should first be moved from the indoor side to the square pipe 56.
Welded in and then bolted to holes 60 in ceiling panel 58
Threading of the tip of 40 is performed. However, it is not only difficult to vertically weld the hanging bolt 40 itself, but also there is a problem that it is not easy to correct the position once the welding is completed.

The present invention was devised to solve the above-mentioned problems of the conventional construction method. Even when a large load is applied to the suspension bolt, the field receiver does not easily tilt, and the load is always applied. The purpose is to provide a construction method that can be received vertically and the hanging position can be easily modified.
