Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a termite prevention construction method for the subfloor surface of a building.

(Prior Art) Conventionally, in order to prevent wooden buildings from being damaged by termites that crawl up from under the floor, or to prevent wooden parts from rotting due to moisture rising from the subfloor, Anti-termite sheets are being installed in the area. By the way, when the above-mentioned termite prevention sheet is laid, if a gap is formed between the wall surface of the concrete cloth foundation or the like and the above-mentioned sheet, there is a possibility that a screw hole that becomes a passage for termites will be formed in this part.

For this reason, as shown in Japanese Patent Application Laid-Open No. 60-105718, a termite-proofing agent is added to a resin, asphalt, or a mixture thereof at the boundary between a wall surface such as a concrete cloth foundation and an anti-termite sheet. The boundary area is sealed by spraying an anti-termite chemical solution. However, when a highly fluid chemical is used as the termite control chemical, it is difficult to concentrate the chemical in the necessary areas because it tends to leak into the surrounding area. When used, it is difficult to spread this chemical solution to every corner of the required area, and in any case there is a drawback that a sufficient seal cannot be achieved.

(Objective of the Invention) The present invention has been made to solve the above-mentioned drawbacks, and regardless of the fluidity of the anti-termite chemical solution used, it is possible to use the minimum necessary chemical solution to form a wall surface such as a concrete cloth foundation. An object of the present invention is to provide an ant-prevention construction method that can easily and reliably seal the boundary between the ant sheet and the ant sheet.

(Structure of the Invention) The present invention lays an anti-termite sheet on the subfloor ground surface, and the peripheral edge of the anti-termite sheet is placed in a groove formed along the boundary between the anti-termite sheet and a wall surface such as a concrete cloth foundation. With this system in place, an anti-termite chemical solution is poured over it.

(Example) Figure 1 shows the lower floor of a building. In this figure, 1 is a concrete fabric foundation, 2 is a concrete fabric foundation 1
This is the subfloor ground surface surrounded by. Above floor ground surface 2
In order to perform the Prevention II construction, five grooves 3 each having a width of about 2 to 3 aa are formed along the base end of the cloth foundation 1.

To form this groove 3, either reduce the amount of soil filled in the vicinity of the cloth foundation 1 when embanking the ground surface 2, or
Or, after embanking the ground surface 2 evenly, the cloth foundation 1
Use an appropriate tool to hold down the area near the.

Next, as shown in FIG. 2, a termite-proofing sheet 4 having moisture-proof properties and containing a termite-proofing agent is spread over almost the entire surface of the subfloor ground surface 2 or along the periphery of the concrete cloth foundation 1 and the bundled stones. Lay it.

Then, nails 5 are driven into appropriate locations of the termite-proofing sheet 4 for temporary fixing, and the peripheral edge of the termite-proofing sheet 4 is introduced into the groove 3. In this case, it is desirable to push the tip of the anti-termite sheet 4 into the soil to prevent the peripheral edge of the sheet 4 from jumping up.

Next, as shown in FIG. 3, by injecting an anti-termite chemical solution 6 along the lower end of the wall surface of the concrete cloth foundation 1 and pouring it into the groove 3, as shown in FIG. An anti-termite structure is obtained in which the boundary between the peripheral edge of the sheet 4 and the wall surface of the concrete cloth foundation 1 is sealed with the anti-termite chemical solution 6.

In this way, the anti-termite chemical solution 6 is poured into the groove 3 that is formed along the base end of the concrete cloth foundation 1 and located at the boundary between the wall surface of the multi-layered foundation la1 and the anti-termite sheet 4. Therefore, even when a highly fluid chemical is used as the chemical 6, it is possible to prevent the chemical from flowing out into the surroundings. Furthermore, even when a chemical solution with low fluidity is used, the location where the chemical solution should be filled is the groove 3.
Since this is known in advance, it is possible to prevent insufficient filling of the chemical solution from occurring. Therefore, irrespective of the fluidity of the chemical solution, the anti-termite chemical solution 6 can be distributed to the necessary locations in just the right amount.

The boundary between the termite-proofing sheet 4 and the wall surface of the concrete cloth foundation 1 is reliably sealed by the termite-proofing chemical 6, and it is possible to prevent mold from forming at this boundary.

In addition, when using a chemical liquid that improves adhesiveness, such as a liquid synthetic resin, synthetic rubber, or asphalt, in which a termiticide is mixed in a solvent such as liquid synthetic resin, synthetic rubber, or asphalt, as the termite-prevention chemical liquid 6,
When this chemical solution 6 solidifies, the concrete cloth foundation 1 and the termite prevention sheet 4 are integrated through this chemical solution 6, and the peripheral edge of the termite prevention sheet 4 is fixed to the wall surface of the concrete cloth foundation 1. I can do it. Therefore, the boundary part can be more reliably sealed with this anti-termite chemical solution 6, and moisture cannot rise from this boundary part and enter the building, or the termite-proof sheet 4 may shift and move. It is possible to effectively prevent the peripheral edge from coming loose from the wall surface of the concrete heavy embankment 1i11.

Note that the location where the anti-termite chemical solution 6 is applied is not limited to the boundary between the anti-termite sheet 4 and the concrete cloth foundation 1. For example, a groove is formed at the boundary between the termite-proof sheet 4 and the peripheral wall surface of the bundled stones,
The groove may be filled with an anti-termite chemical solution 6.

Furthermore, in the above embodiment, after forming the groove 3 along the base end of the concrete cloth foundation 1, the termite-proofing sheet 4 is laid thereon.
The groove portion may be formed by pressing the subfloor ground surface 2 located near the concrete cloth foundation 1 from above after laying the concrete cloth foundation.

(Effects of the Invention) As explained above, in the present invention, the anti-termite chemical solution is poured into the groove formed along the boundary between the anti-termite sheet and the wall surface of the concrete 1 to cloth foundation, etc. Regardless of the fluidity of the anti-termite chemical solution, the chemical solution can be easily and evenly distributed over the boundary area, and there are no screws between the wall surface and the anti-termite sheet that serve as passages for termites. It is possible to reliably prevent the formation of such particles.
