Description

The underfloor control method according to claim 1. TECHNICAL FIELD The present invention relates to an underfloor antproof construction method in a house.

[Conventional technology]

Traditionally, damage to houses by termites has been a problem. This is thought to be because the houses in Japan are made of wood and the climate is humid. This is because termites prefer poor ventilation, warm and humid conditions, and dark places, and they damage moist wood.
Therefore, the floor surface part of the building where such conditions are met is an excellent breeding place for termites.

Therefore, conventionally, as shown in FIG. 17, a termite-proof sheet 32 is laid along the inner side surface of the cloth foundation 30 that is likely to become an ant road so that termites do not come up the cloth foundation 30.
The adhesive tape 34 was attached to eliminate the gap between the two 30 and 32.

However, the adhesive tape 34 is difficult to fit in with the rough surface of the cloth base 30, does not come into close contact with the corners of the cloth base 30 in particular, and has a lack of reliability such as a gap, so that it is impossible to reliably perform ant control.

[Problems to be Solved by the Invention]

There is a termite-proof structure as shown in Fig. 18 as a means to ensure termite control. In this case, a groove 3 is formed near the boundary between the cloth foundation 1 and the ant-preventive sheet 2 on the floor base surface 4 along the inner side surface 1a of the cloth foundation 1. The ant-preventive sheet 2 is laid on the floor base surface 4 so that its edge 2a faces the groove portion 3. Then, a mixed solution 5 of a fluid having an adhesive force and an anti-termite agent is injected and filled in the groove portion 3, whereby the cloth foundation 1 and the anti-termite sheet 2 are adhered to each other, and an anti-termite structure is formed. Is configured. However, in the case of constructing this termite-proof structure, since the fluid that has been conventionally used is a plastic resin such as asphalt or emulsion, the curing speed after injection is slow, and the next work is performed. There was a loss of time.

In view of the above circumstances, an object of the present invention is to be able to immediately shift to the next work.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the underfloor antproof construction method according to the present invention is arranged such that the edge of the ant-proof sheet laid on the floor base surface is arranged close to the inner side surface of the cloth foundation rising from the floor base surface, In the vicinity of the boundary between the ant-proof sheet and the ant-proof sheet, in the underfloor ant-terminated construction method of arranging the ant-repellent agent along the inner surface of the cloth foundation, after arranging the ant-terminated agent near the boundary between the cloth foundation and the ant-proof sheet Then, a curing agent having an adhesive force and an excellent fast curing property is supplied to fix the ant-preventive agent.

In the present invention, as an anti-termite agent, an organic chlorine agent such as chlordane or aldrin, an organic phosphorus agent such as chlorpyrifos, or the like can be used. As a quick-hardening agent,
Use as necessary among epoxy resin-based or polyurethane-based two-component curing agents (adhesives), polyvinyl acetate-based, anaerobic curing agents, reactive acrylic resin-based, rubber-based, hot melt, etc. You can

The termite-proof sheet is made of a sheet-like material such as a sheet of cloth impregnated with rubber or synthetic resin, a sheet of synthetic resin such as polyvinyl chloride, polyethylene, polypropylene, or the like, which cannot be destroyed by termites. In addition, there is a thing aiming at repellent curing by directly impregnating cloth with an anti-termite agent. The synthetic resin sheet or the like may be mixed with an anti-termite agent during the processing step. Also,
By making such an anti-termite sheet moisture-proof, it prevents the warm environment preferred by termites from being formed under the floor and reduces the production of moist wood that termites prefer to eat as much as possible. The anti-termite effect is further enhanced. When the moisture-proof effect is provided in this way, it becomes possible to prevent wood decay and the like caused by a high-humidity condition except damage by termites.

From one to a plurality of dovetail sheets can be used depending on the area under the floor. When using a plurality of termite-proof sheets, in order to prevent termites from entering between them, for example, the edges may be overlapped. In addition, an adhesive tape can be attached on top of the above.

If there is a protrusion such as a boulder on the floor base surface on which the ant-proof sheet is laid, cut out the ant-proof sheet at that portion,
From there, the protrusion may be passed. In that case, in order to prevent termites from entering between the protrusions and the ant-proof sheet, the under-floor ant-proof construction method of the present invention may be applied.

[Action]

By fixing the termite-preventing agent by using a curing agent having excellent quick-hardening property, the adhesive bond between the termite-preventing sheet and the cloth foundation can be quickly obtained.

After placing the termite control agent near the boundary between the cloth base and the termite control sheet, supply the curing agent from above and fix the termite control agent to fix the termite and other cloths. Since the ant-preventive agent is surely placed in the vicinity of the boundary with the ant sheet without a gap, the ant-preventive effect is high.

Since the ant-preventive agent and the curing agent do not come into contact with each other for the first time at the time of construction, there is little concern that the ant-preventive effect of the curing agent will be compromised by the curing agent. This is because if a mixture of anti-termite agent and curing agent is prepared in advance, it will be known for a long period of time during storage of this mixture, and the curing agent of high reactivity before curing will be obtained. Since the ant-preventing agent comes into contact with the ant-preventing agent, the action of the curing agent may gradually impair the ant-preventing curing of the termite-preventing agent.
Even in this invention, at the time of construction, the termiticide and the curing agent come into contact with each other, but the curing agent immediately cures and loses its reactivity.
There is little effect on the termite repellent.

Then, when a two-part curing agent is used, one of them is first poured into the ant-preventing agent arranged in the first to allow it to soak, and then the remaining solution is injected. Since the second liquid is injected in a state in which the ant-proof agent has sufficiently penetrated, the solidified state of the ant-preventive agent can be obtained more effectively.
