In order to achieve the above-mentioned object, according to the present invention, the ceiling structure is mounted on the purlin material by hanging bolts, the ceiling receiving material having the flange portions protruding on both sides, and this mounting operation. It is characterized in that the ceiling material is placed on the flange portion of the obtained ceiling receiving material and the ceiling material is fixed to the ceiling receiving material by a ceiling material fixing metal fitting for preventing upward blow-up.

[0006]

Therefore, according to the present invention, the intersections of the ceiling receiving members are directly or indirectly attached to the purlin members by the hanging bolts by the above-mentioned structure, and both sides of the ceiling receiving members in the frame-shaped portion formed by the ceiling receiving members are attached. The ceiling material is placed on the protruding collar portion, and the ceiling material is fixed to the collar portion of the ceiling receiving material by the ceiling material fixing bracket to construct the ceiling structure. It is not necessary to install it so that it is hidden by the decorative cover, and various materials and ceiling materials of various thickness can be used depending on the shape of the ceiling receiving material, and the ceiling receiving material can be directly attached with the hanging bolts via the hanging metal fittings. Therefore, it is not necessary to provide a base member such as a field edge, and the ceiling can be constructed quickly and easily,
The construction period can be shortened.
