Description

[Detailed Description of the Invention] The present invention aims to improve termite-proof foundation construction methods, and more specifically, to provide a new building foundation that can surprisingly effectively protect wooden buildings from termite damage without causing any environmental pollution. It is related to construction methods.

Termites are pests that feed on wood, and when a house or other building made of wood is repeatedly invaded by termites, the pillars and foundations near the foundation are eaten away, weakening the building from the ground up. A crisis of collapse arises. In particular, because our country has urban conditions where wooden buildings are densely packed,
Feeding damage caused by termites can spread contagiously.

Drastic anti-termite measures are urgently needed.

For this reason, various proposals have recently been made regarding measures to prevent termite damage.

As the most effective method, the so-called "soil treatment method" in which chlordane (oil/emulsion) is sprayed within the construction area has come into widespread use.

However, regarding the soil treatment method as a termite countermeasure, as recently reported in newspapers,
As time passes, chlordane mixes with rainwater and groundwater, causing pollution problems as it flows out and contaminates surrounding wells, rivers, and lakes, and this method is widely used. If this happens, it could lead to a serious situation in terms of public health.

The present invention has been made in view of the above-mentioned problems in conventional methods of preventing termite damage. By skillfully arranging the termites in partitioned areas, the aim is to create a wooden building that does not attract termites at all and is free from the risk of environmental pollution due to leakage of termite control agents.

That is, to explain the present invention based on the illustrated embodiment, an anti-termite sheet 2 containing a termite control agent is spread over a build area A surrounded by a cloth foundation 1, while an anti-termite sheet 2 containing a termite control agent is spread around the outside of the cloth foundation Provided is a termite prevention foundation construction method characterized by installing a dovetail board 3 containing a termite control agent around the perimeter.

In the above, the cloth foundation 1 does not require any special work, and a conventionally known cloth foundation may be constructed as it is. The anti-termite sheet 2 to be laid in the build area A where a building is constructed is usually either an asphalt sheet type or a plastic sheet type made of vinyl chloride resin molded into a sheet shape. Furthermore, as the dovetail board 3 provided around the cloth foundation, a plastic dovetail board made by extruding synthetic resin such as vinyl chloride resin into the desired shape is used. Therefore, it is necessary that these anti-termite sheet 2 and termite board 3 contain a termite-controlling agent, but in this case, preferably termite-controlling agents are used, such as phenitogen, phoxim, chlorpyrifos, acephate, prothiophos, and cyanophos. A fast-acting termite control agent containing at least one organic phosphorus compound selected from the following as an active ingredient and a long-acting stabilizer containing an organic acid metal salt such as zinc octylate or zinc persate as an active ingredient. It is best to use the termites, and if you do so, you can prevent termite damage for 20 to 30 years.

Next, when laying the anti-termite sheet 2 in the built area A, the anti-termite sheet 2 may be buried in the ground, or the second
．． It may also be laid out on the ground as shown in Figure 3. In either case, it is desirable to fold up the edges of the anti-termite sheet 2 slightly along the fabric foundation 1. This is because if there is a gap between the cloth foundation 1 and the termite prevention sheet 2, termites may crawl up the cloth foundation 1 and onto the foundation 4 from there. Therefore, for the best results, it is ideal to arrange the dovetail plate 3 not only on the outer peripheral surface of the cloth foundation 1 (but also on the inner peripheral surface). There are two ways to install it around the cloth foundation 1, as shown in Figure 2, a method of attaching it to the top of the cloth foundation 1 as shown in Figure 3, a method of attaching it with cement mortar 5 interposed on the top of the cloth foundation 1 as shown in Figure 4. A method is adopted in which the dovetail board 3 is nailed to the base 4 fixed on the cloth foundation 1, and the cloth foundation 1 is surrounded by this.

Although the construction method of the present invention is generally as described above, the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims.
For example, various materials can be selected for the termite-proofing sheet 2 carrying a termite control agent, and various shapes can be adopted for the termite cover plate 3.

As explained above, in wooden buildings constructed using the method of the present invention, the termite sheet containing a termite control agent prevents termites from entering from underground in the build area, and termites from outside the build area prevent termites from entering the building area. A termite board containing a termite repellent will repel the invasion of termites.

The foundation and pillars near the foundation will not be damaged by termites, and the termite control agent is stably supported in the material of the termite sheet and termite board and will never leak, making it easy to use conventional soil treatment methods. There is no need to worry about contamination of surrounding wells, rivers, lakes and marshes by mixing with rainwater or groundwater, causing pollution.

In this way, the construction method of the present invention can completely eliminate the problem of environmental pollution that was unavoidable when preventing termite damage caused by conventional soil treatment methods. All termite invasions can be shut out.

Moreover, the method itself can be carried out without any difficult construction work, making it the most ideal termite control technology.
