DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure in which a ceiling can be easily and quickly constructed with a simple structure and from above.

[0002]

2. Description of the Related Art Conventionally, ceiling construction is performed as interior construction work, and is mainly performed from the indoor side. Also, it is difficult to perform the construction almost simultaneously with the construction of the roof for the exterior work.

[0003]

In the construction of the ceiling, there are many ceiling frame members for supporting the ceiling plate and fixing parts such as fixing members to the beams, and the construction is troublesome and time-consuming.

In addition, since it is difficult to construct the roof and the ceiling almost at the same time, it is difficult to construct the roof and the ceiling.
Inconveniences such as an increase in time and cost arise.

[0005]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that the present invention has been applied to flanges of a plurality of structural members, S-shaped fixtures. The formed fixing portion is sandwiched and fixed, and a ceiling plate mounting support member having a hat-shaped cross section is placed on the connecting portion formed on the fixing device so that the plurality of ceiling plate mounting support members are orthogonal to each other between the structural members. Place a flat ceiling plate on the support piece between the ceiling plate mounting supports, place and fix the ceiling plate holding device on the ceiling plate mounting support material, and use the ceiling plate holding device to secure the ceiling. By adopting the ceiling structure characterized by fixing the plate, the ceiling can be roofed from above, and can be constructed almost simultaneously with the construction of the roof, which solves the above-mentioned problem. .
