Abstract

PROBLEM TO BE SOLVED: To provide a termite-proof structure of buildings which is capable of effectively preventing intrusion of termites.SOLUTION: The outdoor side surfaces of a peripheral rising part of a building base are covered with a mixture containing an insecticidal composition having a solubility in water at 20°C of not less than 100 mg/L, and at least one resin selected from the group consisting of an alkyd resin, acrylic resin, amino resin, polyurethane resin, epoxy resin, silicon resin, fluororesin, phenol resin, urea resin, polyester resin, styrene resin, and vinyl resin.

Description

本発明は、布基礎やベタ基礎などの基礎の外周立上がり部の屋外側からのシロアリの侵入を防ぐ建物の防蟻構造に関する。 The present invention relates to an ant-proof structure for a building that prevents termites from invading from the outdoor side of an outer peripheral rising portion of a foundation such as a cloth foundation or a solid foundation.

従来の建物におけるシロアリ防除技術としては、建物の床下の地面から1メートル程度の範囲の木材や建物の下の土壌に、シロアリを駆除できる薬剤を処理する方法やシロアリに少量の薬剤を含む毒餌を摂食させて根絶するベイト工法などの方法が知られている。しかし、上述の建物の床下に薬剤を処理する方法においては、臭気やカビの発生の点で問題がある。また、ベイト工法においては、コロニー全体の活力を衰退させることにあり、その開始から終了までに少なくとも数ヶ月以上を要するという問題がある。
薬剤を使用せずにシロアリの侵入を物理的に阻止する工法も種々提案されている。防蟻シートを、建物基礎に取付けたり、基礎下に敷いて、建物内にシロアリが侵入することを防ぐ防蟻方法が挙げられる。しかし、上述の工法では非常に施工に手間がかかり、また僅かな隙間からシロアリが進入するという問題があった。
Conventional termite control techniques in buildings include a method of treating chemicals that can control termites on wood and soil under the building, which is about 1 meter from the ground under the building floor, and poison baits that contain a small amount of chemicals in termites. Methods such as the bait method that eradicate by feeding are known. However, the above-described method for treating chemicals under the floor of a building has a problem in terms of generation of odor and mold. Moreover, in the bait construction method, there is a problem in that the vitality of the entire colony is reduced, and at least several months are required from the start to the end.
Various methods of physically blocking termite invasion without using a drug have been proposed. There is an ant-proof method that prevents termites from entering the building by attaching an ant-proof sheet to the building foundation or laying it under the foundation. However, the above-described construction method has a problem that construction is very troublesome and termites enter through a slight gap.
