2. Description of the Related Art In general, as an inner wall structure of a building, for example, as shown in FIG. 9, a windproof sheet b is laid on the outer surface of a pillar and a stud, a furring strip c is struck on the outer side thereof, and an outer wall material d is laid on it. A gypsum board e is attached to the insides of the pillars a and studs, a glass wool heat insulating material f is interposed in the space between the windproof sheet b and the gypsum board e, and a wall cloth g such as cloth is attached to the gypsum board e. Known structure.

As a floor structure of a building, for example, there is known a structure in which a subfloor floor board is placed on a joist, and an edge material and a flooring material are attached to the floor board.

[0004]

However, in the case of the above-mentioned conventional gypsum board foundation structure, the heat insulating material f and the gypsum board e are used.
There is a gap H between and, where internal dew condensation occurs, causing various problems, and at the same time, carcinogenic gases such as radon and formaldehyde are released from the gypsum board e and enter the respiratory system of the human body. In addition, the gap H between the heat insulating material f and the gypsum board e serves as an air passage during heating and cooling, and the heating and cooling load becomes large because it moves to the underfloor or ceiling, and the wall body becomes a hotbed for mold and mites. After a while, it has become a factor that causes the building to rot, and in extreme cases, it can be seen that construction can only obtain the heat insulation performance of one gypsum board, and in many cases the heat insulation material is not useful at all. Therefore, there is a large temperature difference between the ceiling surface and the floor surface, making it a cold and fuel-efficient building.
