で、施工性が良い。The procedure for constructing the ceiling structure will be described. A pair of parallel field edge supports 6 and 6 are hung on the beam 5 with a hanging bolt 7. The hanging bolt 7 is inserted from the lower side into the bolt insertion hole 5b provided in the lower flange 5a of the beam 5 as shown in FIG.
The upper beam fixing nut 29 is turned by the tightening tool 33, and the lower flange 5a is tightened by the upper and lower beam fixing nuts 29, 29. As shown in FIG. 5B, the field frame receiver 6 is lifted from below the hanging bolt 7, and the mounting nut 30 on the upper side of the hanging bolt 7 is passed through the large-diameter portion of the Daruma hole 8 of the upper flange 6a. After shifting the suspension bolt 7 laterally so that the suspension bolt 7 is located in the small diameter portion of 8, the lower mounting nut 30 is tightened with the tightening tool 33. At this time, since the recessed recess 9 is formed in the lower flange 6b of the field edge receiver 6 at a position facing the Darma hole 8 of the upper flange 6a, the screwing of the mounting nut 30 by the tightening tool 33 is facilitated. It can be carried out. Further, since the hanging bolt 7 can be inserted into the beam 5 from the lower side as described above, the hanging bolt 7 can be attached to the beam 5 with the curing cover 35 shown in FIG. Therefore, it is not necessary to attach the curing cover 35 at a high place, and the workability is good.
