Abstract

PURPOSE:To make easier an ant preventive treatment for the foundation by setting an ant preventive sheet consisting of an unevenly surfaced sheeted paper containing a termite control agent on the inner surface of the formwork for the foundation. CONSTITUTION:An ant preventive sheet 1 consists of a sheet 2 of synthetic resin or rubbery asphalt containing a termite control agent and an unevenly surfaced 3 releasing paper 5 of a fibrous substance 4. The ant preventive sheet 1 is set on the inner surface of formworks 6 for foundation in such a way that the uneven surface 3 of the sheet 1 is turned toward the concrete placing side and temporarily fixed by an adhesive tape, and concrete 8 is placed into the formworks 6. After the concrete 8 hardens, the formworks 6 are removed out, and the concrete in which the ant preventive sheet 1 is buried so as to cause the uneven surface 3 to act as anchor is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of treating the foundation of a wooden building for termites in order to protect it from termite damage.

Traditionally, termite-proofing treatments for wooden buildings include methods such as spraying the soil on the subfloor surface with an anti-termite agent consisting of an oil, emulsion, or powder containing chlordane as its main ingredient, or applying it to wood on foundations, pillars, etc. It is.

In general, termites nest underground, and they always form an ant trail on the surface of the foundation of a building and climb up, reaching the foundations and pillars of the building and damaging the wood.'' Soil spraying treatment is considered to be the most effective method. However, since the termite agent ``chlordane'' is an organic chlorine insecticide like ``dieldrin,'' which is currently prohibited, its handling is left to specialized contractors, and construction It is inconvenient for the work process, and water contamination caused by the above termite control agents has become a pollution problem, so it is desired to establish a new termite treatment method that is more workable and safe.

In view of these circumstances, this invention has been developed with consideration given to ease of construction, occupational hygiene, and safety, and is a basic construction method for buildings designed to reliably prevent termite damage over a long period of time. It provides law.

An embodiment of the present invention will be described below based on the drawings. The termite-proofing sheet (1) used in this termite-proofing basic construction method is mixed with an organochlorine-based, organophosphorus-based, carbamate-based, or other contact-toxic termite control agent. One side of the sheet material (2) made of synthetic resin or rubber-like asphalt material is roughened (
3), and the unevenness (3) is formed by imparting unevenness to the sheet-like material itself or, for example, by forming the unevenness on the sheet-like material (2).
) may be integrally attached to the surface of the fibrous material (4) so that it does not peel off, and is formed so that it exhibits an anchoring effect on the concrete described later and is embedded without peeling off from the surface of the concrete 1. This is what I did. Also, if desired, a release paper (5) may be attached to the other side of this anti-termite sheet, so that the surface of the anti-termite sheet will not adhere to the concrete during concrete pouring or after foundation formation, which will be described later. It may also be possible to prevent it from being soiled. This release paper (
If 5) is removed immediately before flooring work, the surface of the termite sheet will remain in the same state as when it was formed, and the termite control effect can be expected to be the best.

(1) is a cloth foundation or an independent foundation, etc., with the surface on which the unevenness (3) is formed exposed on the inner surface of the formwork (B), (Ei), that is, concrete Install it so that the uneven surface (3) is exposed on the pouring surface side, temporarily secure it with adhesive tape (7), etc., and then concrete (8).
Pour into the formwork (8), (8). Then, after the concrete 1 is cured, the formwork is removed. At this time, the ant control sea)
As for (1), since the aforementioned unevenness (3) is embedded in the concrete and exhibits an anchoring effect, it remains on the concrete side without peeling off, and a cloth foundation or independent foundation (9) is completed. (1o) is the foundation.

In addition, installing termite-proof sheets is necessary because termites dislike light.
It can be applied around the sides of the foundation inside the building.

As explained above, according to the termite prevention foundation construction method of this invention,
It has the feature of being extremely easy to construct because it is possible to construct a termite-proofed foundation by temporarily fixing a termite-proofing sheet to the inside surface of the foundation forming form and pouring concrete. Moreover, since this termite control sheet contains the termite control agent mentioned above,
The pest control agent does not leak outside, anyone can handle it, there are no operational restrictions, and it is ideal as a building material in terms of ease of construction and occupational hygiene.

In addition, in such termite-proof foundations, the sides of the foundation are covered with termite-proof sheets, so termites are unable to come into contact with this and form termite trails due to their repellent action, and this ensures that termites do not rise. This makes it possible to prevent ants and maintain the anti-termite effect for a long period of time.

Claims (1)

[Claims] A formwork for forming a fabric foundation or an independent foundation of a building, etc. by using an anti-termite sheet made by adding unevenness to one side of a sheet made of a synthetic resin or t-h rubber-like asphalt material mixed with a termite-control agent. After temporarily fixing the uneven surface to the inner surface of the concrete, pour concrete into the formwork, and when removing the formwork after the concrete has hardened, place the anti-termite sheet on the side surface of the concrete. An anti-termite foundation construction method characterized by leaving the foundation in place to form a cloth foundation or an independent foundation.
