Description

[Detailed explanation of the invention] [Industrial application field] The present invention is a new proposal regarding termite-proof construction materials.
More specifically, it is a new type of termite-proof construction material that can be tightly fitted to the hem corners of the cloth foundation and the surface of the subfloor to prevent termites from climbing up, and can be installed simply and quickly. It is related to.

[Conventional technology and technical issues to be solved]

As is well known, in the past, the so-called soil treatment method, in which termite control agents such as chlordane were spread, was widely used as a method of protecting buildings from termite damage, but recently, such termite control agents have been widely used. As time passes, it has been pointed out that water gets mixed into groundwater and sewage and is washed away, causing contamination of surrounding rivers, lakes and marshes.

For this reason, the applicant proposed a termite control technology for buildings that does not pollute the environment and is effective against termites, by applying a termite control agent to the building area surrounded by a fabric foundation. The so-called "ant-proof sheet laying method" that involves laying sheets all over the place.
(Refer to Japanese Patent Application Laid-Open No. 59-96351). However, in this method of installing an anti-termite sheet, if special care is not taken in finishing the hem of the fabric foundation, creases in the sheet tend to form at the bottom hem corner where the anti-termite sheet contacts the fabric foundation. If there were any gaps there, there was a risk that termites would crawl up and damage the foundation.

The key point of this invention to solve the above-mentioned drawbacks of the conventional "termite prevention sheet installation method" is that when termites damage a building, a contact termite path is always formed on the side of the cloth foundation to approach the wooden part. It was completed after focusing on the termite's habit and obtaining experimental results that if the key route from the surface of the subfloor to the side of the fabric foundation was blocked, termites would no longer be able to form an ant trail. It can be installed easily and quickly without the need for technical skills, and the termite belt is elastically crimped to the fabric foundation so tightly that there is literally no space for ants to crawl out, making it impossible for termites to crawl up. The purpose is to provide an anti-termite belt that is free from deterrence.

[Technical configuration adopted to solve the problem]

The technical configuration adopted by the present invention to solve the above problems will be described below with reference to illustrated examples.

That is, according to the present invention: an anti-termite sheet 1 consisting of a belt-shaped sheet containing an anti-termite agent dispersed therein; Flexible part 21 made of synthetic resin
is integrally molded with a long plastic hinge 2 which is given restoring elasticity in the flat direction, and is capable of being crimped in an L-shape at the hem corner of the fabric foundation B and the subfloor surface G. is provided.

To explain the illustrated example in more detail, the termite-proofing sheet 1 is usually an EVA resin film, a vinyl chloride film, a polyethylene film, a rubberized asphalt sheet, etc., in which a termite-proofing agent is dispersed. Preferred examples of termiticides to be mixed here include organophosphorus insecticides (e.g., fenitrothion, phoxim, chlorpyrifos, acephate, prothiophos, cyanophos, tetrachlorpinphos, etc.) and organic acid metal salts. (e.g. zinc octylate,
zinc versatate, etc.),
Or carbamate insecticides (MIPC agents, BPMC
1-naphthyl N-methylcarbamate, etc.) are adsorbed and supported on amorphous silicon dioxide.

The long plastic hinge 2 fixed on the anti-termite sheet 1 consists of a flexible part 21 and a wing part 22. Usually, the flexible part 21 is made of soft resin (for example, soft vinyl chloride), and the wing part is made of soft resin (for example, soft vinyl chloride). The portion 22 is made of hard resin (for example,
It is integrally molded using a well-known co-extrusion method using a material (semi-rigid or rigid vinyl chloride). In this case, it is of course possible that an appropriate termiticide may be mixed into the resin constituting the hinge 2, if desired. Note that the reference numeral 23 in FIG. 2 is a nail hole into which the nail N is to be driven.

The long plastic hinge 2 may be fixed to the anti-termite sheet 1 by fusing with high frequency, or by bonding with an adhesive (for example, double-sided adhesive tape) 24. All that is required is to connect both 1 and 2 so that they work (see FIGS. 5 and 6).

[Construction example]

The suppressive termite-proof band of the present invention may be used alone as shown in FIG. 1, or in combination with other termite-proofing materials as shown in FIGS. 7 to 9. ``Anti-termite sheet laying method'' first proposed by
It may also be used as a part of the product.

Figure 1 shows an example of construction in which the termite-proof belt is placed along the hem corner of the cloth foundation B and the subfloor surface G, and the termite-proof belt 1 is placed along the hem corner by the action of the long plastic hinge 2. You will be severely suppressed. In addition, the first
In the construction example shown in the figure, a method is adopted in which a holding nail N is inserted into a nail hole 23 made in the plastic hinge 2 and fixed to the ground surface G as appropriate. In addition, when disposing the termite prevention belt of the present invention at the hem corner of the cloth foundation B, for example, when the cloth foundation B is at a bending corner, it is necessary to have sheet extensions 11 at both ends as shown in FIG. It is best to use a
In addition, in a place where the cloth foundation B continues in a straight line, a hinge extension part 25 at one end, as shown in FIG.
The other end has a seat extension 11, and the seat extension 11 has a hinge extension 25.
It is convenient to arrange them while overlapping each other.

Figure 7 shows that in addition to the construction shown in Figure 1, an anti-termite paint P containing an anti-termite agent is applied to the inside surface of the cloth foundation B. Figure 8 shows that anti-termite paint P is also applied to the outside surface. Fig. 9 shows a case in which, in addition to the construction example shown in Fig. 7, an anti-termite board 3 impregnated with an anti-termite agent is laid on the upper surface of the cloth foundation B. Although the restraining and termite belt of the present invention can sufficiently control termites by installing it as shown in Figure 1,
Naturally, it becomes even more reliable when used in combination with other anti-termite materials as shown in Figure 9.

[Operations and effects of the present invention]

As explained above, in the anti-termite belt of the present invention, the anti-termite sheet 1 is restored to the flat direction by the long plastic hinge 2, so that it is connected to the cloth foundation B and the subfloor surface G. When the cloth foundation B and the termite-proofing sheet 1 are disposed at the hem corner of the sheet, the cloth foundation B and the termite-proofing sheet 1 are tightly fitted, and there is never a gap where termites can crawl up, and termite damage can be effectively prevented.

Moreover, the termite-proof belt of the present invention can be easily moved by simply placing it on the bottom corner of the cloth foundation B and fixing it to the ground surface G with appropriate nails. Since it can be prevented, construction can be done very quickly.

In this way, the termite-proof belt of the present invention eliminates the need for finishing work on the hem corners of the fabric foundation, which was unavoidable and time-consuming in the conventional method of laying termite-proof sheets, and it can also be used alone. In addition to exhibiting a sufficient termite control effect, the structure is extremely simple and reduces material and construction costs, making it highly practical.
