By the way, an attempt has been made to omit the flint beam conventionally used in order to maintain the rigidity in the surface direction in the cabin, and to use a high-rigidity CLT (Cross Laminated Timber) plate as a surface material instead. This CLT board has a heavier gravity than the conventionally used gypsum board, plywood, and the like.

Considering the case where such a CLT plate is used as a face material, there is room for improvement in the conventional structure including the structure disclosed in Patent Document 1 from the viewpoint of workability. That is, in the construction method disclosed in Patent Document 1, when a CLT board is used as a ceiling material, the CLT board is fixed to the field edge while maintaining the state in which the CLT board is lifted from below. It must be, workability is poor, and there is a problem in safety.
