It becomes possible. Further, for example, since the ceiling member functions as a work floor, it is not necessary to separately install a scaffold for performing work on the ceiling side, and workability can be improved. Further, for example, the number of working steps can be reduced, so that the working cost can be reduced. Further, for example, the worker can work on a stable ceiling member that functions as a work floor rather than on a scaffolding that is separately erected, so that it is possible to improve safety. In addition, for example, even when a worker drops a tool or the like during work on the ceiling side, since the ceiling member that functions as a work floor receives the tool, a fallen object falls below the ceiling member. Danger can be eliminated and safety can be improved.

According to the ceiling structure of the second aspect, since the ceiling member is placed on the second support member, it is possible to reliably prevent the ceiling member from falling, so that the safety is improved.

Also, it is made of metal and can be constructed by using a steel pipe.

The “fixing portion” 31 is a fixing means for fixing the steel material 3 to the upper chord member 2. Although the specific type and configuration of the fixing portion 31 is arbitrary, for example, it is fixed to the lower end portion of the upper chord member 2 by an arbitrary fixing method (for example, welding or an arbitrary fixing method including bolts and nuts). The steel material 3 is configured to be received and supported, and the steel material 3 is fixed.

(Structure-Filling material)
The packing material 4 in FIGS. 3 and 4 is the packing material described above.

(Construction method)
Next, a construction method of the ceiling structure 100 thus configured will be described. 5 and 6 are plan views of the ceiling structure under construction.

First, the steel material 3 is fixed to the upper chord member 2 provided as shown in FIG. 1 as shown in FIG. Although it is specifically arbitrary, for example, the steel material 3 is orthogonal to the upper chord member 2 and is provided on the lower side (−Z direction) of the upper chord member 2 by using the fixing portion 31 of FIG. It is fixed by an arbitrary fixing method (for example, an arbitrary fixing method including a bolt and a nut).
