Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a basic structure which has been subjected to a termite repellant treatment in order to protect the foundation and pillars of a wooden building from termite feeding damage.

[Conventional technology and its problems]

Usually, termites nest in the ground and ascend while forming an ant road along the foundation of the building, and they damage the wooden foundation and pillars above the foundation. In order to protect the wooden structure from the feeding damage of the termites, the soil treatment method inside and outside the floor by the termiticide or the wood treatment method such as the foundation and the pillar is performed.

As such a chemical, "chlordane", which is an organochlorine insecticide, has been used for many years, but recently the chemical component remained in rivers and lakes developed into a problem of environmental pollution, and its use was prohibited. . Instead, organic phosphorus, pyrethroids, carbamates and other insecticides have come to be used. Although such a drug has a fast-acting property, it has little potential to accumulate in soil or water, and therefore has no harmful effect on water pollution. However, it is easily hydrolyzed and easily decomposed into alkali, and is not suitable for use on the outside of a building, and is used exclusively for the treatment of underfloor soil in a building.

Termites hate light and outside air, form a tunnel called an ant road, and due to the nature of moving inside, it is possible to achieve that purpose by treating 90% of the inside of the building, but the term called a termite is a building Although it also forms an ant road from the outside of the tree and rises up, it has the property of damaging xylem,
The use of the above termite control chemicals outdoors is unsuitable from the viewpoint of the attenuation of the chemical effect due to decomposition and the outflow of chemicals due to rainwater, and under such circumstances, the termites were vulnerable to intrusion from the outside.

[Means for Solving the Problems]

Therefore, in order to prevent termite invasion from the outside of the building for a long time without impairing the safety of the present invention, an inorganic material mixed with an anti-termite agent was applied to the outer surface of the cloth foundation of the wooden building. Provide an ant-prevention foundation structure.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. As the inorganic material 1 in which an anti-termite agent is mixed, a dry-curable inorganic powder such as gypsum, plaster or cement, chlorpyrifos, etc. The organic phosphorus insecticide, the pyrethroid insecticide, the carbamate insecticide, or a mixture of two or more kinds thereof. When mixing, the insecticide component may be used as it is, but depending on a material having strong alkalinity such as cement, it may be mixed into microcapsules. The mixed amount is 0.1 to 5.0% by weight based on the inorganic powder when it is dried and cured. In order to apply the inorganic material mixed with this ant-repellent agent to the side surface of the cloth foundation 2 of the building, first, the powder of gypsum, plaster or the like is mixed with the insecticide component and water in the above-mentioned amount. The obtained mixture is kneaded to have a predetermined viscosity. The viscosity at this time should be such that it can be applied with a plaster trowel. When spraying with high-pressure air for coating, the viscosity is lower than this. Further, if desired, a pigment or the like is added for coloring. 0.5 to 20 mm on the side of the building cloth foundation
Apply to a thick thickness. From the appearance, it is natural to apply it to the entire side surface of the cloth foundation, but from the termite-preventing effect, it is sufficient to apply it in a band shape partially, and the important thing is to apply it to the entire length of the circumference of the cloth foundation. That is. If the dog running 3 is present, it may be applied to this surface. In particular, a gap is likely to be formed later at the joint between the cloth foundation 2 and the dog running 3, and termites will rise from this gap, so it is effective to apply the coating so as to fill this portion. Reference numeral 4 is a base, and 5 is a pillar.

The inorganic material mixed with the ant-preventive agent thus applied to the cloth base completely adheres to the surface of the cloth base and is dried and cured to form a tough ant-preventive layer. This ant-preventive layer prevents the ant-preventive agent from being decomposed from rainwater or ultraviolet rays for a long time.

[Effect of device]

As described above, since the foundation structure of the present invention is formed by coating the side surface of the cloth foundation with the inorganic material mixed with the termite control agent, even if the termites rise above the ground, the termite control agent in the inorganic material is used. Due to the repellent effect, it is possible to prevent the termites from climbing up to the upper part of the foundation, and thus to completely prevent damage to the wood such as the foundation.

In addition, since the above-mentioned termite control agent is integrally supported in the inorganic material, it is easy to handle, and unlike the conventional method in which the termite control agent is directly sprayed on the soil, the agent may be scattered. It is characterized by excellent safety and long-lasting efficacy of the drug.
