The foundation 12 has an inverted T-shaped cross-sectional shape in which an upright portion 12b rises from the center of a horizontally extending bottom portion 12a, and the lower half of the bottom portion 12a and the upright portion 12b is buried in the soil. Then, the base 1 is placed on the upper surface 12c of the upright portion 12b.

うに土台１４へ至る蟻道２３が形成されてしまうおそれ
がある。The termites, which are enemies of houses, use the darkness as their range of action. Therefore, when the heat insulating material 22 does not exist outside the foundation 12, the termites crawl from the outside of the foundation to the base 14 side. Will not come up. However, when the heat insulating material 22 is installed on the outside of the foundation as shown in the figure, the heat insulating material 22 is generally made of a foamed resin such as expanded polystyrene, expanded polyethylene, or expanded polyurethane. Since the termites can break through the heat insulating material 22 from the part buried in the soil, there is a possibility that an ant path 23 leading to the base 14 is formed as shown in FIG. is there.

ある。In addition to the case where the heat insulating material 22 is applied to the outside of the foundation as described above, for example, the heat insulating material 22 is applied along the inner surface of the foundation in a state where the interstitial concrete 16 is not cast inside the foundation. Also in this case, there is a possibility that the heat insulating material 22 will be eroded from the soil to form an ant path.

By fixing the portion protruding from the lower end of the heat insulating material to the upper surface of the base bottom with an adhesive having a termite-proof function,
The lower end portion of the heat insulating material can be reliably covered with the termite-controlling sheet, and the termite-controlling effect of the adhesive itself used for fixing can be further enhanced.

いる場合も含む概念である。Here, the phrase “the heat insulating material is disposed on the base bottom” is not limited to the case where the lower end surface of the heat insulating material is in contact with the upper surface of the base, but these surfaces are separated from each other. This is a concept that also includes cases in which the spacers are interposed and spacers are interposed between the surfaces.

率をより高めることができる。The heat insulating material may be applied to the side after the foundation is completed. However, a termite sheet is fixed to one side of the heat insulating material in advance. Simultaneously with placing the foundation, if the termite control sheet is disposed on the side of the foundation in a state facing the side opposite to the foundation, construction efficiency can be further improved.

を構築することができる。The heat insulating material for basic heat insulation is disposed on the outside of the foundation at the same time that the base is cast, with the termite control sheet facing outward, and the heat insulating material protrudes above the upper surface of the foundation. If the part is cut off and the upper end face of the termite sheet is placed on the cut off surface, the construction efficiency is higher than the method of arranging the heat insulating material after the placement of the foundation is completed, and A favorable termite-proof structure can be constructed only by disposing the heat insulating material.

The lower end 24a is fixed to the upper surface of the base bottom 12a with an adhesive 26 containing a termiticide, and the upper end 24b is covered from above on the upper surface of the heat insulating material 22. Then, a termite control tape 28 is attached to the termite control sheet upper end 24b and the base upper surface 12c so as to straddle them, so that the termite control sheet upper end 24b is fixed to the upper surface of the heat insulating material 22. The base 14 is placed on the termite tape 28.

It is preferable to select and mix effective ones from various insecticides such as However, in the present invention, regardless of the specific type of the termitic component contained in the termite-controlling material, the base material may not have a moisture-proof property such as a nonwoven fabric. The same applies to the components contained in the termite tape 28.

The heat insulating material 22 may be applied with the spacer interposed. Also in this case, the lower end of the termite sheet 24a covering the heat insulating material 22 may be bonded to the base bottom 12a.

(B)) The heat insulating material 22 shown in FIG. 1 may be installed after the installation of the foundation 12 is completed. However, if it is arranged at the same time as the installation of the foundation 12, the construction efficiency is improved. Increase. Therefore,
In this embodiment, as shown in FIG. 2A, a termite-control sheet 24 is previously fixed to one side of the heat-insulating material 22 to form a heat-insulating material having a termite-control function. However, the upper end of the termite sheet 24 is not fixed to the upper end of the heat insulating material 22, and both are in a state where they can be separated. Also,
The lower end 24a of the termite control sheet 24 is larger than the lower end of the heat insulating material 22, and the lower end 24a is wrapped to the back side so as to cover the lower surface of the heat insulating material 22.
a is fixed to the heat insulating material 22.

Moreover, the upper end of the heat insulating material 22 and the upper end 24b of the termite sheet
Is not fixed, as shown in FIG.
After cutting off the heat insulating material portion (that is, the upper end portion of the heat insulating material) protruding from the upper surface 12c of the base 12, aligning the height with the upper surface 12c of the base 12, the termite control sheet is placed on the heat insulating material upper surface formed by the cut. By covering the upper end 24b,
The termite-control effect can be further enhanced.

分における断熱材２２の保護が可能である。In this method, the termite-control sheet lower end 24a does not necessarily need to be wrapped around the lower end of the heat insulating material 22. However, if it is wrapped around in this way, a more reliable termite-controlling effect can be obtained. For example, even when the lower surface of the heat insulating material 22 is separated from the upper surface of the base bottom 12a, the termites break through the heat insulating material 22 from the lower surface. Can be prevented beforehand. The upper end portion 24b is also provided with a heat insulating material 22 as shown in the figure.
