[0003]

However, in the termite-preventing treatment such as the former, since the agent is sprayed on the soil, the efficacy of the agent is likely to decrease due to the evaporation of the agent, and a sufficient termite-preventing effect is exerted. You may not be able to On the other hand, if the entire floor surface is covered with an ant-proof sheet, such a problem can be solved, but in the conventional construction method, since the foundation and joists are installed while the ant-proof sheet is attached, There is a problem that the construction is complicated. Further, in the floor portion of the panel construction method, an anti-termite sheet can be attached in advance to the lower surface of the panel, but the joint portion between the panels requires anti-termite treatment, which makes the construction complicated.

An object of the present invention is to provide a termite-preventing method and a termite-preventing structure capable of improving workability at a construction site and ensuring a sufficient termite-proofing effect.

[0005]

Therefore, the present invention aims to achieve the above object by adopting the following constitution. The invention according to claim 1 is an ant-proof construction method for ant-proofing the floor portion 22 formed on the foundation of the buildings 2 and 2B, the length being larger than the dimension between the side surfaces of the rising portion 211 of the foundation.

In the invention of this configuration, by fixing the indoor side end of the ant-proof sheet to the lower surface of the floor, the edge of the floor is covered with the ant-proof sheet, and the termites raise the rising part of the foundation from the ground on the indoor side. Therefore, the route to the floor can be blocked, and the floor can be protected from termites. Further, since the side surface of the floor portion and a part of the lower surface of the floor portion are directly covered with the termite sheet, the floor portion is reliably protected.

According to a third aspect of the present invention, in the ant-proof construction method of the first or second aspect, after the step of fixing the outdoor side end portion of the ant-proof sheet to the outer wall portion, the waterproof attached to the outer wall portion. It is characterized by including a step of covering the upper end of the outdoor side end portion of the termite-proof sheet with the flexible sheet 231. Here, as the waterproof sheet, it is conceivable to adopt a moisture-permeable waterproof sheet used in an exterior ventilation method or the like. In the invention of this configuration, since the outdoor end of the ant-proof sheet is covered with the waterproof sheet, rainwater does not enter through the gap between this end and the outer wall.

According to a fourth aspect of the present invention, an ant-proof structure 1, 1A, 1 for ant-proofing the floor 22 formed on the foundation of the building 2 is used.
B, 1C, 1D, which has a length dimension larger than the dimension between the side surfaces of the rising portion between the floor portion and the rising portion 211 of the foundation, 11A.
And the outdoor side end portions 111 and 111A of the ant-proof sheet protruding to the outdoor side of the foundation disposed on the outer periphery of the building among the foundations are the outer wall portions 23 provided on the upper surface of the floor portion. It is characterized by being fixed to.

In the invention of this structure, since the outdoor end of the ant-proof sheet is fixed to the outer wall, the lower end of the outer wall and the side surface of the floor can be covered with the ant-proof sheet. It is possible to reliably prevent termites from entering the ground and protect the floor. Furthermore, by fixing the outdoor end of the ant-proof sheet to the outer wall part, for example, the outer wall base material and providing the outer-wall finishing material, the ant-proof sheet is prevented from being directly exposed to rainwater, so that the ant-proof sheet is impregnated. The drug does not elute and the duration of the effect of the ant-preventive sheet can be kept longer.

According to a fifth aspect of the present invention, in the termite control structure according to the fourth aspect, the indoor side end portion 112 of the termite control sheet is fixed to the lower surface of the floor portion. In the invention of this configuration, by fixing the indoor side end of the ant-proof sheet to the lower surface of the floor, the edge of the floor is covered with the ant-proof sheet, and the termites raise the rising part of the foundation from the ground on the indoor side. Therefore, the route to the floor can be blocked, and the floor can be protected from termites. Further, since the side surface of the floor portion and a part of the lower surface of the floor portion are directly covered with the termite sheet, the floor portion is reliably protected.

According to a sixth aspect of the present invention, in the termite-preventing structure according to the fourth aspect, the indoor end portion of the anti-termite sheet is in a state where the indoor-side end portion 112A of the anti-termite sheet is not fixed. Is flexible enough not to adhere to the side surface of the rising portion.

Normally, a ventilation hole for ventilating the space below the floor is formed in the rising portion of the foundation, and is flexible enough to prevent the termite sheet from sticking to the side surface of the rising portion. By doing so, even if you do not fix the indoor side end to the bottom of the floor, you will not completely block the ventilation hole,
It does not impair the ventilation of the space below the floor. In addition, since the work of fixing the end portion to the floor is unnecessary, the construction does not take time.

According to a seventh aspect of the present invention, there is provided an anti-termite structure according to any one of the fourth to sixth aspects, in which the anti-termite sheet below the upper end of the outdoor side end of the anti-termite sheet has an anti-termite property. It is characterized in that a drainer 12 having an ant return 122 is provided. In the invention of this configuration, since the ant-repellent barbs are formed on the drainer, the termites that try to enter the floor through the rising part of the foundation cannot enter beyond the ant-prevention folds. , The floor can be protected more reliably from termites.

Although the outdoor side end portions 111 and 111A of the anti-termite sheets 11 and 11A are covered with the sheet 231, no gap is formed between this end portion and the outer wall panel 230 of the outer wall portion 23. As long as the ant-proof sheet can be attached, the end does not have to be covered.

Further, the drain 12 has a ant repellant 122.
However, the termite repellant barb 122 may not be formed. However, if the water drainer 12 having the termite repellent 122 is attached, it is possible to reliably prevent the termite from entering. In addition, a termite-proof barb separate from the drainer may be attached. However, as in the above-mentioned embodiment, if the ant-repellent barb is formed in the drainer, the number of members can be reduced, and the construction work does not require labor.

In the above-mentioned embodiment, the termite prevention sheets 11, 11 are used.
Although the dovetail preventive sheets 11 and 11A are temporarily fixed to the rising portion 211 by passing the anchor bolt 213 through A, it is possible to fix them temporarily by another method, for example, by fixing them to the upper surface of the rising portion 211 with an adhesive or the like.

The drug does not elute and the duration of the effect of the ant-preventive sheet can be kept longer.

According to the second aspect of the present invention, by fixing the indoor side end of the termite control sheet to the lower surface of the floor section, the edge of the floor section is covered with the termite control sheet, and the termites on the indoor side. The path from the ground to the floor through the rising part of the foundation can be blocked, and the floor can be protected from termites. Further, since the side surface of the floor portion and a part of the lower surface of the floor portion are directly covered with the termite sheet, the floor portion is reliably protected.

According to the third aspect of the invention, since the outdoor end of the ant-proof sheet is covered with the waterproof sheet, rainwater does not enter through the gap between this end and the outer wall. .

According to the fourth aspect of the present invention, since the outdoor end of the ant-proof sheet is fixed to the outer wall, the lower end of the outer wall and the side surface of the floor can be covered with the ant-proof sheet. Therefore, it is possible to reliably prevent termites from entering the floor, and the floor is protected. Furthermore, by fixing the outdoor end of the ant-proof sheet to the outer wall part, for example, the outer wall base material and providing the outer-wall finishing material, the ant-proof sheet is prevented from being directly exposed to rainwater, so that the ant-proof sheet is impregnated. The drug does not elute and the duration of the effect of the ant-preventive sheet can be kept longer.

According to the fifth aspect of the present invention, by fixing the indoor side end of the termite control sheet to the lower surface of the floor section, the edge of the floor section is covered with the termite control sheet, and the termites on the indoor side. The path from the ground to the floor through the rising part of the foundation can be blocked, and the floor can be protected from termites. Further, since the side surface of the floor portion and a part of the lower surface of the floor portion are directly covered with the termite sheet, the floor portion is reliably protected.

According to the sixth aspect of the invention, the termite sheet has such flexibility that it does not come into close contact with the side surface of the rising portion. Therefore, the indoor end does not need to be fixed to the lower surface of the floor. It does not completely block the pores and does not impair the ventilation of the space below the floor. In addition, since the work of fixing the end portion to the floor is unnecessary, the construction does not take time.

According to the seventh aspect of the present invention, since the termite repellant barb is formed in the drainer, the termites that try to enter the floor through the rising part of the foundation go beyond this termite barb. It can not invade and can protect the floor part more reliably from termites.
