[Problems to be solved by the device]

 However, in the above-mentioned prior art, in the former case, in order to lock the reinforcing rib locking portions 11 and 11 to the reinforcing ribs 30 of the deck plate 29 at the time of construction, first, as shown in FIG. The diagonal portions 15a, 15a of the above are engaged with the notches 14, 14 of the reinforcing rib engaging portions 11, 11 and in this state, the upper portion of the reinforcing rib engaging portions 11, 11 is slightly bent in the direction of arrow a. It is rotated and temporarily fixed with the screw 12 and the nut 13 with a seat, and then the reinforcing rib locking portions 11 and 11 are locked to the reinforcing ribs 30 of the deck plate 29 as shown in FIG. Tighten the nut 13 with a seat, screw the upper end of the hanging bolt 16 into the upper nut 15 as shown in FIG. 20 and FIG. 21, and tighten the lower nut 17 to fix it. Yes, and in the latter case, as shown in FIG. The frame-shaped reinforcing rib locking members 19, 19 are left open, and then the reinforcing rib locking notches 18, 18 of the frame-shaped reinforcing rib locking members 19, 19 are set as shown in FIG. After locking to the reinforcing ribs 30 of the deck plate 29, the frame-shaped reinforcing rib locking members 19 and 19 are tightened with the screws 23 and the seat nuts 24, and further, as shown in FIG. Since the upper end of the hanging bolt 26 is screwed into the nut 25 and the lower nut 28 is tightened and fixed to complete the construction, in the case of the above-mentioned conventional technique, the reinforcing rib locking portions 11, 11 ( The former) or the reinforcing rib locking members 19, 19 (latter) require screws 12, 23 and nuts 13, 24 for attaching to the reinforcing ribs 30 of the deck plate 29, and the structure is complicated accordingly. And many parts Not only was it difficult to handle, but it was also difficult to handle.As a result, it took a lot of time and effort to mount it on the deck plate reinforcing ribs, and the workability was extremely low. There was a problem that the required number of suspension bolts could not be easily installed and used at the site when needed.

[0004]
