Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an underfloor termite prevention method in a house.

[Conventional technology]

Damage to houses caused by termites has traditionally been a problem. This is thought to be due to the fact that Japan's houses are made of wood and the climate is humid. This is because termites prefer poor ventilation, warm and humid conditions, and dark places, and feed on damp wood.

Therefore, the ground under the floor of a building, which has these conditions, is a perfect breeding ground for termites.

Therefore, conventionally, as shown in FIG. 17, an anti-termite sheet 32 is laid along the inner surface of the cloth foundation 30, which is likely to become an ant trail.
In addition to preventing termites from climbing up the cloth foundation 30,
Furthermore, an adhesive tape 34 was attached to eliminate the gap between the two parts 30 and 32.

However, the adhesive tape 34 does not blend well with the rough surface of the cloth foundation 30, and does not adhere particularly well to the corners of the cloth foundation 30.
It was unreliable, such as creating gaps, and it was not possible to reliably prevent termites.

[Problem to be solved by the invention]

An anti-termite structure as shown in FIG. 18 is a device that can reliably prevent termites. In this product, a groove 3 is formed near the boundary between the cloth foundation 1 and the anti-termite sheet 2 on the subfloor surface 4 so as to extend along the inner surface 1a of the cloth foundation 1. The anti-termite sheet 2 is laid on the floor subsurface 4 with its edge 2a facing into the groove 3. Then, a mixed liquid 5 of an adhesive fluid and an anti-termite agent is injected and filled into the groove 3, thereby adhering the cloth foundation l and the anti-termite sheet 2, thereby preventing termites. The structure is constructed. However, when constructing this anti-termite structure, the fluids conventionally used were, for example, asphalt or plastic resins such as emulsion, so the curing speed after injection was slow, and it was necessary to move on to the next work. There was a time loss. In view of the above circumstances, an object of this invention is to enable a user to immediately move on to the next task. [Means for Solving the Problems] In order to solve the above-mentioned problems, the underfloor termite prevention construction method according to the present invention involves placing the edge of the termite prevention sheet laid on the subfloor surface close to the inner surface of the fabric foundation rising from the subfloor surface. In the under-floor termite prevention construction method, in which a termite-proofing agent is placed along the inner surface of the cloth foundation near the boundary between the cloth foundation and the termite-proofing sheet, the termiticide has adhesive strength. Use a hardening agent with excellent fast curing properties to fix the product. In this invention, as the termiticide, organic chlorine agents such as chlordane and aldrin, organic phosphorus agents such as chlorpyrifos, etc. can be used. As a quick hardening agent,
Use epoxy resin-based or polyurethane-based two-component curing agents (adhesives), polyvinyl acetate-based, anaerobic curing agents, reactive acrylic resin-based, rubber-based, true melt, etc. as necessary. Can be done. The anti-termite sheet may be made of a sheet-like material that termites cannot tear through, such as cloth impregnated with rubber or synthetic resin, or a sheet of synthetic resin such as polyvinyl chloride, polyethylene, or polypropylene. Furthermore, there is a method that aims to harden and repel termites by directly impregnating the cloth with termiticide. The synthetic resin sheet etc. may be mixed with a termiticide during the processing process. Also,
By making such termite-proof sheets moisture-proof, it will prevent the formation of a warm environment that termites like under the floor, and it will minimize the creation of damp wood that termites like to eat. The anti-termite effect is further enhanced. When a moisture-proofing effect is provided in this way, it is also possible to prevent wood rot caused by high humidity conditions, excluding damage caused by termites.

The termite-proofing sheet can be used from one sheet to a plurality of sheets depending on the area under the floor. When using multiple anti-termite sheets, the edges may be overlapped, for example, to prevent termites from entering between them. In addition, if there is a protrusion such as a pile of stones on the subfloor surface on which the above-mentioned termite-proof sheet is laid, which can be layered with adhesive tape, cut out the termite-proof sheet in that area. , you can pass a protruding object through it. In that case, the underfloor termite prevention method of the present invention may be applied to prevent termites from entering between the protrusion and the termite prevention sheet. [Function] By fixing the termite control agent using a hardening agent with excellent quick curing properties, adhesive bonding between the termite control sheet and the fabric foundation can be quickly obtained. Then, if a two-part hardening agent is used, one part of which is first poured into the termiticide placed earlier and soaked in, and the remaining liquid is injected into the first part.
Since the second liquid is injected after the liquid has sufficiently soaked into the termiticide, the termiticide can be solidified more effectively. [Embodiments] This invention will be described in detail below with reference to drawings showing embodiments thereof. FIG. 1 shows an example of an underfloor termite prevention structure obtained by the underfloor termite prevention method according to the present invention. As shown in the figure, in this underfloor termite prevention method, the inside surface of the cloth foundation 1 is placed near the boundary between the cloth foundation 1 and the termite prevention sheet 2 on the subfloor surface 4.
A groove portion 3 is formed along the line a. The termite-proofing sheet 2 is laid on the floor subsurface 4 with its edge 2a facing into the groove 3. In the groove 3, a mixture 5' of a two-component curing agent and a termite inhibitor, which has adhesive strength and excellent quick hardening properties, is placed in a hardened and solidified state. The cloth foundation 1 and the anti-termite sheet 2 are adhered to each other by a mixture 5'. In the figure, 1b is a footing part buried underground, and IC is a rising part rising from this footing part 1b onto the subfloor surface 4, forming an inverted T-shaped cloth foundation I. In addition, 6.7 is a foundation made of cracked stone and concrete, and 8 is a base made of wood.When constructing such an underfloor termite prevention method, first, the subfloor surface 4.
Then, a groove 3 is formed along the inner surface 1a of the cloth foundation 1 (Fig. 2). The method of forming the groove 3 is not particularly limited in the present invention, but for example, a jig having a shape corresponding to the groove 3 is pressed against the subfloor surface 4 while moving in a direction along the inner surface 1a. A method in which the groove portion 3 is formed by this method is preferable. In a method using such a jig, by simply pressing the jig against the underfloor 4, it becomes possible to easily form the groove portion 3 of a constant shape at all times.

Next, the edge 2 is placed on the subfloor surface 4 as described above.
An anti-termite sheet 2 is laid so that the end a faces into the groove 3, and the sheet 2 is fixed with nails 10 or the like. Thereafter, the edge 2a is placed in the groove on the sheet edge 2a along the groove 3.
Apply granular (or liquid) termiticide I5 along the

(FIG. 3) Then, the first liquid 2 of the two-component curing agent is poured into the groove 3 from the can l1 so as to be mixed with the termiticide l5.
0 (Figure 4). As a result, the first liquid 20 is
It soaks into the granular termiticide 15 previously supplied into the groove 3 so as to cover the intergranular spaces and the entire surface thereof (FIG. 6). Thereafter, the second liquid 21, which is the remaining liquid of the two-component curing agent, is injected into the groove 3 from another can 11' (Fig. 5). Then, the second liquid 21 is injected into the state where the first liquid 20 has soaked into the termiticide 15 (Fig. 6), and both liquids 20 and 21 immediately react and harden, causing the termiticide l5 The particles are bonded to each other, and the anti-termite sheet 2 and the cloth base 1 are bonded to each other by curing of the two liquids 20 and 21.

In this way, an underfloor termite-proof structure as shown in FIG. 1 is obtained.

Next, a second example will be explained. In the under-floor termite-proofing structure, as shown in FIG.
It is pressed inside. The sheet pressing member 12 is
As shown in Fig. 8, it is made by bending a band of metal or plastic into a substantially key shape. And the diagonal piece 12a
While pressing down the edge 2a of the anti-termite sheet 2, insert the vertical piece 12b at the tip into the groove 3 along the inner surface 1a of the cloth foundation 1, and form the nail 1O into the horizontal piece 12c. The sheet pressing member 12 and the termite-proofing sheet 2 are thereby fixed to the subfloor surface 4. In the construction of this embodiment as well, a two-component curing agent is used to fix the termite control agent 15. Note that the shape of the sheet holding member 12 as described above is limited to that shown in FIG. Not done. For example, the horizontal piece 12
c, the same piece 12C. If a claw-like protrusion that projects more downwardly is provided in place of the nail 10, the nail 10 can be omitted.
You will be able to perform construction similar to the above. As shown in FIG. 9, if the sheet pressing member 12 is made long,
The edge 2a of the termite-proofing sheet 2 can be pressed down over its entire length, and more reliable termite-proofing can be achieved. As shown in FIG. 10, the elongated sheet pressing member 12 has a cross-sectional shape with an upwardly opened groove 12f, which is inserted into the groove 3. The two-component mixture 5' of a fast-curing curing agent and an anti-termiticide is mixed, hardened, and solidified within the groove 12f. In this case, the cloth foundation 1 and the sheet pressing member 12 are bonded together with this mixture 5', and the sheet pressing member 12 and the anti-termite sheet 2 are bonded together by the claw-like protrusions 12e protruding from the lower surface of the sheet pressing member l2.・
It is fixed to the subfloor surface 4 by. Therefore, similar effects can be obtained.

The embodiments shown in FIGS. 11 and 12 take this idea further. That is, in this embodiment, as shown in FIG. 11, the edge 2a of the anti-termite sheet 2 is pressed onto the subfloor surface 4 by the sheet pressing member l3 driven into the subfloor surface along the inner surface 1a of the cloth foundation 1. The groove portion 3 is fixed to the
The inner surface la of the cloth foundation 1 and the upper surface 1 of the sheet pressing member l3 provided at a predetermined angle with the inner surface la.
3a. The sheet pressing member 13 includes claw-like projections 13b, and these projections 13
b..., the edge 2a of the termite-proof sheet 2 is attached to the floor subfloor surface 4.
, thereby providing fixation. Note that, instead of the projections 13b, a strip-shaped hanging piece may be used that hangs downward along the lower side of the sheet pressing member 13. Further, although the sheet pressing member 13 has a curved shape, it may also be a flat plate in the form of a strip. It is installed in an oblique position so that the upper end gradually separates from the cloth foundation 1, and the mixture 5 of the curing agent and termiticide is placed between the diagonal surface and the cloth foundation 1.
′ is placed. Next, the embodiment shown in FIG. 13 will be explained.

In this embodiment, the groove 3 is formed by forming a damming body 14 on the edge 2a of the termite prevention sheet 2 laid on the subfloor surface 4, so that the damming body 14 and the inner surface 1 of the cloth foundation 1
It is designed to be formed between a. As the material used for the dam body 14, materials commonly used at construction sites, such as sand, soil, or mortar, can be used. In the figure, 5' is a mixture of curing agent and termiticide. The other parts are the same as those in the previous embodiments and can be made of the same material.
The example shown in Figure 4 will be explained. In this embodiment, a groove 3 is formed between the cloth foundation 1 and a damming body 4a formed by raising the subfloor surface 4 along the inner surface 1a of the cloth foundation 1, and is formed at the edge of the anti-termite sheet 2. The difference from the previous embodiments is that the edge 2a extends beyond the dam body 4a and faces into the groove 3. The dam body may be formed in advance when the subfloor surface 4 is formed. Further, after the subfloor surface 4 is formed, sand, soil, mortar, etc. may be heaped up in the same manner as in the embodiment shown in FIG. 13 above. In the figure, 5' is a mixture of curing agent and termiticide. Next, the embodiments shown in FIGS. 15 and 16 will be explained. In these embodiments, the groove 3 allows the edge 2a of the termite-proofing sheet 2 to stand up along the inner surface 1a of the cloth foundation l, and the fixing member 16 allows the termite-proofing sheet 2 to stand up along the inner surface 1a of the cloth foundation l.
By fixing in that state, the anti-termite sheet 2 and the cloth foundation 1
In the embodiment shown in FIG. 15, such a fixing member l6 is made of double-sided adhesive tape, so that the edge 2a of the anti-termite sheet 2 is fixed to the fabric foundation. It is raised along the inner surface 1a of 1 and is attached to this side 1a. In this way, the upwardly opened portion of the end edge 2a of the erected anti-termite sheet 2 is used as the groove portion 3. Further, in the embodiment shown in FIG. 16, such a fixing member l6 is a nail. In this embodiment, first, the edge 2a of the termite-proofing sheet 2 is folded upward and stood up, and then the edge 2a is overlapped on the termite-proofing sheet 2, and this overlapped part is fixed with the nails. Fix it to the floor subsurface 4 using the member 16. Then, an upwardly opened groove 3 is formed between the raised portion of the edge 2a and the inner surface 1a of the cloth foundation 1. The same groove 3 is used. In these figures, 5' is a mixture of curing agent and termiticide. In addition, in each of the above embodiments, it was an essential requirement to form a groove, but in the underfloor termite prevention method of the present invention,
This may also be done without forming the same groove.

〔Effect of the invention〕

As described above, the underfloor termite prevention method according to the present invention fixes the termite agent placed near the boundary between the fabric foundation and the termite prevention sheet using a hardening agent that has adhesive strength and excellent quick hardening properties. As a result, the anti-termite sheet and the fabric foundation can be bonded together quickly, allowing you to move on to the next task immediately. By using a two-component curing agent, the termiticide can be solidified more effectively.
