However, when the ceiling panel is hung by the ceiling hanging metal fittings to construct the ceiling, since the outer peripheral edge of the ceiling panel is located directly below the center of the beam in the blow-out portion, the ceiling panel is left as it is. So you can't stick inner wall boards. For this reason, a shielding member for covering the beam and the ceiling panel between the ceiling panel and the floor panel on the floor and a mounting member for the shielding member are required, which not only complicates the work but also increases the number of parts. There was a problem that the cost would rise.

For the purpose of making the ceiling incombustible and improving the strength of the ceiling base material, the applicant of the present invention has filed Japanese Patent Application Laid-Open No. 6-240802.
As described in the publication, it is also proposed to construct a ceiling by forming a steel ceiling frame by forming a steel material into a rectangular frame and fixing the steel ceiling frame to the beam with the above-mentioned ceiling hanging bracket. However, it is not possible to deal with the above-mentioned problems of the blowout part.

The present invention has been made in view of the above problems, and when the ceiling is formed by the steel ceiling frame and the ceiling hanging metal fitting, the ceiling structure of the blow-out portion can be easily constructed. Is provided.
