[0014]
The construction member B is composed of a fixing member C and a cover member D as shown in FIGS.
[0015]
As shown in FIG. 4A, the fixing member C includes a base material 9 (shown in FIG. 4C) and a locking member 10 (shown in FIG. 4D). The fixing member C is integrated with an adhesive or engagement.
[0016]
The base material 9 has functions of a fireproof material, a heat insulating material, a raising material, a soundproof material, and the like. The materials include plywood (OSB), cement board, calcium carbonate board, calcium silicate board, ceramic board, wood piece cement board, magnesium carbonate board, sizing board, sizing insulation board, etc., or glass fiber, whisker, aramid, etc. Fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc. mixed by extrusion molding, press molding, injection molding, paper making, etc., or various fibers are woven in a cross or three-dimensional shape , Steam-cured or fired, molded into a panel by impregnating cement, clay, etc., or a sandwich panel in which synthetic resin foam is laminated between thin metal plates, between a rigid substrate and a sheet It consists of a sandwich panel formed with a synthetic resin foam. Of course, it is also possible to use a member (a canapé structure, a sandwich structure, etc.) in which these are combined as the base material 9.
[0017]
The locking member 10 is formed of a horizontal surface 11, a side surface 12 in which both end edges of the horizontal surface 11 are bent inward, and a locking piece 13 in which the tip of the side surface 12 protrudes inward.
[0018]
