The moisture-proof concrete that shields the underfloor space and the ground surface in the enclosed area is provided. A heat insulating material does not necessarily have to be provided on the side surface of the portion of the cloth foundation that is the inner peripheral portion of the building. The inner cloth foundation that does not follow the outer periphery of the building may or may not be covered with a heat insulating material. According to this configuration, the heat insulation material covering the cloth foundation provides underfloor heat insulation against the cold air outdoors. This cloth foundation is continuous around the entire circumference of a building, etc., and the ground inside is warm compared to the cold air outside, so even if no heat insulating material is applied to the floor, it is sufficient Excellent heat insulation. Also, since the underfloor space and the ground surface are shielded by the moisture-proof concrete,
The moisture from the ground does not reach under the floor, and the underfloor ventilation port can be omitted. Since the underfloor ventilation port can be omitted in this manner, the cool air outdoors does not enter the underfloor, and excellent heat insulation can be ensured while the structure is designed to insulate the floor part by the cloth foundation part.
Moreover, since the underfloor ventilation port can be omitted, it is not necessary to provide an opening in the cloth foundation or attach a ventilation port cover.

In this way, when the heat insulating material is also used as the mold, the work of disassembling the mold can be omitted, and the time and effort for separately mounting the heat insulating material are not required. Further, even when the cloth foundation has a cross-sectional shape having a base portion and a rising portion, concrete pouring can be performed only once. An underfloor moistureproof sheet may be provided on the lower surface of the moistureproof layer concrete. With this configuration, it is possible to more reliably prevent the intrusion of moisture from the ground. Further, in this case, the moisture-proof layer concrete functions as “moisture-proof layer holding concrete”. Further, below the moisture-proof layer concrete, an embankment whose upper surface level is higher than that of the ground surface around the building may be provided. With this structure, the underfloor space above the moisture-proof concrete can be lowered, and the amount of moisture trapped in the underfloor space can be reduced accordingly. Also, on the upper surface of the cloth foundation,
A long base made of shaped steel may be arranged along the longitudinal direction, and the outdoor surface of the base may be covered with a base cover having a heat insulating property. With this configuration, it is possible to reliably prevent cold air from entering the underfloor from the base portion.

熱効果が一層向上する。According to this foundation structure, the heat insulating materials 2a and 2b of the cloth foundation 1 insulate the underfloor from the cold air outside. Further, the underfloor space A is shielded from the ground surface by the moisture-proof layer concrete 3 and the underfloor moisture-proof sheet 4, so that moisture is not transmitted from the ground to the underfloor, and the underfloor ventilation port can be omitted. In this way, since the underfloor ventilation port can be omitted, outdoor cool air does not enter the underfloor, and excellent heat insulating properties can be ensured while having a structure in which the heat insulating materials 2a and 2b of the cloth foundation 1 are used to insulate the floor. Therefore, it is not necessary to apply heat insulation to the floor panel 16 on the first floor. Further, since it is possible to prevent the invasion of moisture as described above, it is not necessary to perform the moisture-proof construction on the floor panel 16.
In addition, since the underfloor ventilation port can be omitted, it is not necessary to provide the fabric foundation 1 with an opening serving as a ventilation port or to attach a ventilation port cover. When embankment is applied under the moisture-proof layer concrete 3 to lower the underfloor space A, the volume of moisture under the floor is reduced, and the influence of moisture on the floor surface can be more reliably prevented. The moisture barrier concrete 3 is the floor panel 16
The underfloor space A may be almost eliminated by making it close to the lower surface of the.
Since the heat insulating materials 2a and 2b of the cloth foundation 1 also serve as a mold, the work of disassembling the mold is unnecessary, and the cloth foundation 1 has a cross-sectional shape having a base portion 1a and a rising portion 1b. However, you can do the concrete pouring once. As a result, the foundation, plasterer and woodwork are simplified and the workability is improved. Further, since the base 6 made of shaped steel is arranged along the longitudinal direction on the upper surface of the cloth foundation 1 and the outdoor surface thereof is covered with the base cover 9 with a heat insulating material, cold air can also intrude from the base portion to the underfloor. It can be surely prevented, and the heat insulation effect of the floor of the building is further improved.

Since a moisture-proof layer concrete that shields the underfloor space and the ground surface in a wide range is provided, it is possible to reduce the work related to moisture and heat insulation such as plastering work and wood work while achieving excellent heat insulation and moisture resistance. It becomes easier and the working time can be shortened.
Also, when the heat insulating material is placed on both sides of the cloth foundation and used as a material for the formwork, it is only necessary to place the foundation concrete once, and the work of dismantling the formwork and the work of separately installing the heat insulating material are required. Can be omitted. When the underfloor moistureproof sheet is provided on the lower surface of the moistureproof layer concrete, the moistureproof effect is further improved. When embankment is installed under the moisture-proof concrete so that the upper surface level is higher than the ground surface around the building, the space under the floor above the moisture-proof concrete will be low, and the moist traps under the floor will be eliminated more reliably. You can In addition, if a long steel top made of shaped steel is arranged along the longitudinal direction on the upper surface of the cloth foundation, and the outdoor surface of this base is covered with a heat insulating top cover, cold air from the base part Invasion can be prevented, the heat insulation effect is further improved, and the heat insulation construction of the base part is simple.
