Description

The present invention relates to a basic heat insulating structure having an ant-proof function and a construction method thereof.

In recent years, as the heat insulation and airtightness of houses have progressed, the use of a foundation insulation method in which a heat insulating material is constructed on the inside and outside of the foundation has been actively adopted instead of a floor insulation method in which a heat insulation material is constructed on the floor.

An example of the heat insulation structure is shown in FIG. In the figure, a foundation 12 is placed on the ground 10. The foundation 12 has an inverted T-shaped cross section in which the upright portion 12b rises from the center of the bottom portion 12a extending in the horizontal direction, and the bottom half of the bottom portion 12a and the upright portion 12b are buried in the soil. And the foundation 14 is installed on the upper surface 12c of the upright part 12b, and the soil concrete 16 is cast in the inner side area | region (FIG. 6 right side area | region) of the foundation 12. As shown in FIG.

Here, in a normal foundation structure, a finishing wall 20 made of mortar or the like is provided outside the upright portion 12b via a lath 18, but in the illustrated structure, the lath 18 and the basic upright portion 12b are provided. The heat insulating material 22 is interposed between the outer surface and the lower surface of the heat insulating material 22 is in contact with the upper surface of the foundation bottom portion 12a, and the upper surface of the heat insulating material 22 is substantially the same height as the upper surface 12c of the upright portion 12b. Is located.

Since the white ants that are enemies of the house use darkness as their range of action, when the heat insulating material 22 does not exist outside the foundation 12, they do not creep up from the outside of the foundation to the base 14 side. However, when the heat insulating material 22 is constructed outside the base as shown in the figure, the heat insulating material 22 is generally made of a foamed resin such as expanded polystyrene, expanded polyethylene, expanded polyurethane, etc. Since the white ants eat away the heat insulating material 22 from the buried portion in the soil, there is a possibility that an ant road 23 leading to the base 14 is formed as shown in FIG. is there.

Moreover, not only when the heat insulating material 22 is constructed on the outer side of the foundation as described above, but also when the heat insulating material 22 is constructed along the inner side surface of the foundation without the soil concrete 16 being placed on the inner side of the foundation. In addition, there is a possibility that the heat insulating material 22 is eroded from the soil and an ant road is formed.

For this reason, in the past, it has been required to determine whether or not to use the basic thermal insulation method shown in the figure, taking into account the ant habitat and damage conditions around the construction site. This is the current situation.

In view of such circumstances, the present invention is a basic heat insulating structure having an ant-proof function capable of preventing white ants from entering through the heat insulating material while forming a good temperature environment using the heat insulating material. It aims at providing the method of constructing.

The present invention provides a base insulation heat insulating material in which the upper part of the heat insulating material is left on the one side of the heat insulating material and the upper portion of the heat insulating material is fixed to be peeled off. At the same time as the installation, the ant-proof sheet is disposed outside the foundation in a state of facing outward, and a portion of the heat insulating material that protrudes upward from the upper surface of the foundation is cut out, and the portion on the cut surface is This is a method of covering the upper end surface of the ant proof sheet.

By adopting the method of the present invention, a heat insulating material is disposed on the side of the foundation (that is, at least one of the outside and the inside of the foundation), and the outer surface and the upper end of the heat insulating material are covered with an ant-proof sheet. Can be constructed.

According to this structure, it is possible to form a good temperature environment by disposing a heat insulating material on the outside of the foundation, and by covering the outer side surface and the upper end portion of the heat insulating material with the anti-rust sheet, It is possible to prevent the white ants lying in the soil from eating away the heat insulating material, and it is possible to prevent the white ants from entering the building through the heat insulating material.

Therefore, by adopting the method of the present invention, it is possible to construct a basic heat insulating structure that can prevent white ants from entering the building side through the heat insulating material while forming a favorable temperature environment. .

Moreover, since the method of the present invention uses the heat insulating material for basic heat insulation in which the top is left on one side of the heat insulating material and the ant proof sheet is fixed, the ant proof sheet faces the outside simultaneously with the placement of the foundation. In the state, it is possible to construct a basic heat insulating structure with a good ant-proof function by simply disposing the heat insulating material for basic heat insulating outside the base. That is, the construction efficiency can be increased as compared with the method of disposing the heat insulating material after completing the foundation placement in advance.

Moreover, the heat insulating material for basic heat insulation is configured in a state in which the upper part of the termite-proof sheet and the upper part of the heat insulating material can be peeled, and the heat insulating material is disposed outside the base, It is possible to further enhance the ant-repellent effect because a part of the material that protrudes above the upper surface of the foundation is cut out and the top surface of the ant-proof sheet is put on the cut surface. Become.

Further, the heat insulating material for basic heat insulation used in the method of the present invention is such that the lower end portion of the ant protection sheet is left behind the lower surface of the heat insulating material, and the lower side of the heat insulating material covers the lower surface of the heat insulating material. In order to obtain a more reliable ant-repellent effect, it is preferable to wrap around.

As described above, when the method of the present invention is adopted, it is possible to construct a structure in which a heat insulating material is disposed on the side of the foundation and the outer side surface and the upper end of the heat insulating material are covered with an ant-proof sheet. Therefore, it is possible to construct a basic heat insulating structure that can prevent white ants from entering through the heat insulating material while forming a favorable temperature environment.

Furthermore, it is possible to construct a basic heat insulation structure with a good ant-prevention function simply by disposing the heat insulating material for the base heat insulation outside the foundation while the ant-proof sheet faces the outside simultaneously with the placement of the foundation. Therefore, construction efficiency can be increased.

Moreover, since the upper end surface of the ant proof sheet is placed on the surface of the heat insulating material cut, the ant proof effect can be further enhanced.

Embodiments of the present invention will be described with reference to the drawings. In the following embodiments, the structure other than the part related to the ant protection treatment is basically the same as that shown in FIG. 6, and the same elements are denoted by the same reference numerals and the description thereof is omitted. To do.

1) First embodiment (FIG. 1, FIG. 2 (a), FIG. 2 (b))
In this embodiment, the structure shown in FIG. 1 is applied. In this structure, the ant-proof sheet 24 is disposed between the heat insulating material 22 and the lath 18 in the structure shown in FIG. That is, the ant-proof sheet 24 is disposed outside the heat insulating material 22, and the lath 18 and the finishing wall 20 are constructed on the ant-proof sheet 24.

The ant protection sheet 24 is disposed so as to cover the entire outer surface of the heat insulating material 22, and the lower end 24 a and the upper end 24 b protrude beyond the lower surface and the upper surface of the heat insulating material 22, respectively. And the said lower end part 24a is fixed to the upper surface of the base bottom part 12a with the adhesive agent 26 containing an ant-proofing agent, and the upper end part 24b has covered the upper surface of the heat insulating material 22 from the outer side. And the ant-proof sheet upper end part 24b is fixed to the upper surface of the said heat insulating material 22 by affixing the ant-proof tape 28 on these so that it may straddle over this upper part 24b and the base upper surface 12c. The base 14 is installed on the ant-proof tape 28.

Examples of the ant-proof sheet 24 include a synthetic resin sheet having moisture resistance such as polypropylene, polyethylene, and ethylene vinyl acetate, pyrethroid insecticides (silafluophene, etofenprox, bifenthrin, etc.) and organophosphorus insecticides. It is preferable to select one that is effective from various insecticides. However, in the present invention, regardless of the specific type of the ant-preventive component contained in the ant-proof material, the base material may not be moisture-proof, such as a nonwoven fabric. The same applies to the components contained in the ant-proof tape 28.

Although the specific component of the adhesive 26 is not limited, for example, the aforementioned insecticide is contained in asphalt or an appropriate emulsion (emulsion of synthetic resin such as acrylic or urethane, or emulsion of synthetic rubber such as SBR). What was mixed is suitable. The adhesive 26 can be omitted as appropriate.

Next, a method for constructing the structure will be described.

First, as shown in FIG. 2 (a), an ant-proof sheet 24 is fixed to one side surface of the heat insulating material 22 in advance to form a heat-insulating material with an ant-proof function (corresponding to a heat insulating material for basic heat insulation). However, the upper end portion of the ant protection sheet 24 is not fixed to the upper end portion of the heat insulating material 22, and both are made to be peelable. Moreover, the lower end part 24a of the ant-proof sheet 24 is left more than the lower end of the heat insulating material 22, and the lower end part 24a is thermally insulated in a state where the lower end part 24a is turned around to cover the lower surface of the heat insulating material 22. The material 22 is fixed.

And the heat insulating material 22 is arrange | positioned simultaneously with placement of the foundation 12, and as shown in FIG.2 (b), the heat insulating material part (namely, heat insulating material upper end part) protruded from the upper surface 12c of the foundation 12 is excised. After aligning the height of the upper surface 12c of 12 and the heat insulating material upper surface formed by the excision, the ant-proof sheet upper end portion 24b is placed over the structure to construct the structure.

According to this structure, since the heat insulating material 22 (particularly the buried portion in the soil) is covered from the outside by the ant-proof sheet 24, there is no possibility that the heat insulating material 22 is broken even if it is applied to the outside of the foundation 12. . Therefore, it is possible to prevent the white ants from creeping up toward the base 14 by using the heat insulating material 22 as an ant road.

The upper end surface of the heat insulating material 22 is also covered with the ant-proof sheet 24 and the ant-proof tape 28, and the lower end 24a of the ant-proof sheet 24 is covered with an adhesive 26 containing an ant-proof component. Since it adheres to 12a, protection of heat insulating material 22 can be strengthened more.

Furthermore, according to this construction method, it is possible to construct a basic heat insulating structure with a good ant-prevention function simply by placing the heat insulating material 22 on the outer side at the same time as placing the base 12. That is, since the heat insulating material 22 is arranged simultaneously with the placement of the foundation 12, the construction efficiency can be improved as compared with the case where the heat insulation material 22 is arranged after the foundation 12 is placed. it can.

In addition, after the heat insulating material portion protruding from the upper surface 12c of the foundation 12 is cut out to have the same height as the upper surface 12c of the foundation 12, the top portion 24b of the ant protection sheet is placed on the upper surface of the heat insulating material formed by the cutting. Therefore, the ant-proof effect can be further enhanced.

Note that the lower end surface of the heat insulating material 22 does not necessarily contact the upper surface of the base bottom portion 12a, and the heat insulating material 22 floats from the base bottom portion 12a, or a spacer different from the heat insulating material is interposed therebetween. You may construct the heat insulating material 22 in the made state.

Further, in this method, the ant-proof sheet lower end portion 24 a does not necessarily have to go around the lower end portion of the heat insulating material 22. However, if it wraps around in this way, a more reliable ant protection effect can be obtained. For example, even if the lower surface of the heat insulating material 22 is separated from the upper surface of the foundation bottom portion 12a, the white ants eat away the heat insulating material 22 from the lower surface. This can be prevented in advance.

2) Second embodiment (FIG. 3)
In this embodiment, instead of the ant-proof tape 28 shown in the first embodiment, the packing 30 shown in the first embodiment is interposed between the base upper surface 12c and the base 14. Yes. A cover portion 30 a extends from the packing 30 to the outside of the foundation 12, and the packing 30 is disposed so that the cover portion 30 a covers the upper end portion 24 a of the termite-proof sheet 24 and the upper end surface of the heat insulating material 22. In addition, the cover part 30a is subjected to an ant-proofing treatment.

As a means for applying an ant-proofing treatment to the cover 30a, an ant-proof tape 34 may be affixed to the upper surface of the cover 30a as shown, or the entire packing 30 including the cover 30a is integrally formed. At this time, at least the cover part 30a (more preferably, the entire packing) may be impregnated with the termite-proofing agent. In the latter case, the number of steps for manufacturing the packing 30 is reduced, and the mass productivity is further increased.

According to the above structure, the use of the packing 30 can enhance the airtightness under the floor, and can effectively use the packing 30 to enhance the ant-proof effect.

3) Other Embodiments In the above-described embodiment, the ant-proof sheet 24 is used to perform the ant-proof treatment of the heat insulating material 22, but the heat-insulating material 22 is a foamed synthetic resin plate mixed with an ant-proofing agent. (The material of the ant-proofing agent may be the same as that of the ant-proofing sheet 28), and the heat insulating material 22 can be protected from white ants. Moreover, the ant-proof effect is further enhanced by the combined use of the ant-proof agent-containing heat insulating material and the ant-proof sheet.

In the present invention, regardless of the specific type of the foundation 12, the present invention can be widely applied to the case where a heat insulating material is applied to the side of the foundation regardless of whether it is a fabric foundation or a solid foundation. Moreover, the specific cross-sectional shape of the foundation 12 is not limited to the inverted T-shape as shown in the figure, and may be any shape as long as a heat insulating material can be applied to the outside.

For example, as shown in FIG. 4 as the third embodiment, when a solid foundation in which the soil concrete 16 is integrated as the foundation bottom portion 12 a ′ is placed as the foundation 12, generally, the foundation is moved to the outside of the foundation 12. In this case, the bottom part 24a of the ant protection sheet 24 is caused to wrap around the back side of the heat insulating material 22 as shown in the drawing, and the bottom part 24a of the heat insulating material 22 is caused by the ant protection sheet lower end part 24a. What is necessary is just to cover a lower end surface.

In each of the above embodiments, the case where the heat insulating material 22 is applied to the outside of the foundation 12 is shown, but the present invention is not limited to this. For example, in the case where the heat insulating material 22 is constructed on both the inside and outside of the foundation 12 and the case where the heat insulating material 22 is constructed only on the inside of the foundation 12, when the soil concrete 16 is not constructed inside the foundation, Since the material 22 may be eroded and an ant road may be formed, the present invention can be effectively applied even in such a case. As an example, in the fourth embodiment shown in FIG. 5, when the heat insulating material 22 is constructed on both the inner and outer sides of the foundation 12, the inner and outer heat insulating materials 22 are respectively covered with the ant proof sheets 24. The upper end is fixed to the base upper surface 12c with a common ant protection tape 28.
