的とするものである。[0003] When this type of earthen floor is used, although the earthen floor is made of concrete, there is no insulation material surrounding the outer circumferential surface of the cloth foundation, so in cold regions, the freezing depth ( 60~100cm)
In some cases, the cold spreads from the cloth foundation to the earthen floor, cooling the entire earthen floor, and at the same time, the heat stored in the earthen floor is dissipated into the soil, making it difficult to insulate, and the moisture in the soil It spreads from the cloth foundation to the earthen floor, making the use of moisture-proof sheets pointless and having poor moisture-proofing properties. In cold regions, when cloth foundations and earthen floors absorb moisture, they freeze during the cold season, causing cracks and shortening the lifespan of earthen floors. The purpose of the present invention is to propose an earthen floor that eliminates these problems.

The cloth foundation 1 and the foam insulation material 2 are constructed at the same time after the base concrete 13 is constructed by assembling base reinforcing bars 11 and cloth reinforcing bars 12 on the ballast 9 laid after root digging 10. The cloth foundation 1 and the foam insulation material 2 consist of an inner formwork 14 that stands up on a base concrete 13, and a foam insulation material 2 that is removably fixed to the entire circumferential surface of one side of the outer formwork 15.
It is constructed by pouring cloth concrete between the foamed heat insulating material 2 and the outer formwork 15 placed on the side and raised on the base concrete 13. The cloth foundation 1 and the foam insulation material 2 can be constructed at the same time by removing the outer formwork 15 from the foam insulation material 2 after the cloth concrete has hardened, and both are closely integrated, significantly reducing concerns about peeling and improving insulation properties. Moisture resistance is improved.

以上であっても差支えない。The foam insulation 2 and the foam insulation material 6 are as follows:
A well-known foamed polystyrene resin (foamed polystyrene resin with a thickness of about 50 mm) is used. In addition, the above-mentioned heat insulating material 2,
The thickness of 6 is not limited to 50mm, but 50mm
There is no problem even if it is more than that.
