Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foundation structure treated with anti-termite treatment to protect the foundations and columns of wooden buildings from termite damage.

[Conventional technology and its problems]

Termites usually nest underground and climb up along the foundations of buildings while forming ant trails, damaging the wooden foundations and pillars above the foundations. To protect wooden buildings from the damage caused by termites, methods such as treating the soil under the floor with anti-termite chemicals or treating the wood of foundations, pillars, etc. are carried out.

However, the main ingredient of these termiticides is the same organic chlorine insecticide as Deldrin, whose use is currently prohibited, and they come in the form of oils, emulsions, powders, etc., so they must be handled only by specialized construction professionals. It is left to the person.

The use of such chemicals is not safe from an occupational health perspective, and as soil treatment agents have recently developed into a pollution problem that contaminates groundwater and rainwater, it is necessary to consider their safety. There is.

In addition, as in Utility Model Application Publication No. 51-150608, a structure has been devised in which a sheet impregnated with insecticide is sandwiched between the foundation and the foundation to prevent termites from climbing up. Since the overhanging part of the sheet was not wide enough, dirt, dirt, etc. adhered to the back side of the overhanging part, and the initial termite return effect did not last, and there was a drawback that termites could easily climb over the overhanging part.

[Means for solving problems]

Therefore, the present invention places emphasis on safety, has a strong termite-proofing effect, protects wooden buildings from termite damage over a long period of time, and provides a foundation structure that is easy to construct.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the embodiment shown in the drawings. One longitudinal end of the anti-termite sheet 1 mixed with or coated with an anti-termite agent is placed on the top end of the cloth foundation 2. A wooden base 3 is installed on top, and the other lengthwise piece of the anti-termite sheet is hung down along the inner wall of the cloth foundation, one end of which rests on the foundation structure buried in the subfloor soil. The anti-termite sheet 1 is made by mixing a soft synthetic resin or asphalt having rubber-like elasticity with an anti-termite agent such as chlordane or an organic phosphorus insecticide, or applying the agent to a base material such as a nonwoven fabric that is separately adhered to the surface of the sheet. , is formed by laminating layers. Then, one end of the termite-proof sheet is backfilled into the soil under the floor with soil 4
Embed it together and finish. 7 indicates GL.

As mentioned above, termites nest underground, and as they climb up and damage foundations, pillars, etc., they form a path above the foundation to prevent them from climbing up. In the present invention, the ends of the termite-proof sheet are embedded in the subfloor soil so as to wrap around the entire side surface of the cloth foundation, so termites that climb up along the side surface of the cloth foundation are completely eliminated. can be blocked.

[Effect of idea]

As explained above, the foundation structure of the present invention is constructed so that the top end and inner wall surface of the cloth foundation are covered with an anti-termite sheet mixed with or coated with an anti-termite agent, so that termites form an ant trail from underground. However, even if they were to crawl along the inside surface of the foundation, they would not be able to climb up because the space between the wooden foundations is completely blocked by the anti-termite sheet.
It can completely prevent wood damage.

The termite-proofing agent mixed or applied to the termite-proofing sheet is a contact poison that kills insects upon contact, so termites may pierce the termite-proofing sheet itself or cause ants to form on the surface of the termite-proofing sheet. You can't even form a path.

In addition, since the above-mentioned anti-termite agent is integrally supported on the anti-termite sheet, it is easy to handle, and unlike the conventional method of spraying an anti-termite agent made of oil, etc., the agent does not scatter. It has the advantage of being extremely safe and can be constructed by ordinary workers. It also has the characteristic of long-lasting drug efficacy.
