Description

The present invention relates to an insect-proof structure capable of preventing insects from entering the under-floor space of a building and ensuring air permeability of the under-floor space, and a method for constructing the insect- proof structure .

  In order to prevent the invasion of white ants into the space under the floor of the building, a process of spraying an ant protection agent to the foundation and soil is performed. In general, soil treatment is intended for soil treatment in the foundation and is not performed on the outer periphery of the foundation in principle. Therefore, for example, there is a problem that white ants climb the foundation along a fine gap between the makeup mortar applied to the outside of the rising part of the foundation and the rising part, and enter the underfloor space through the gap between the rising part and the base. It was. Usually, the cosmetic mortar is painted up to a portion hidden by a draining plate covering the upper end of the rising portion. For this reason, there was a problem that it was difficult to detect the invasion of white ants. Further, when a wooden deck is installed next to the building, there is a problem that white ants enter the space under the floor from the gap between the wooden deck and the foundation.

  Therefore, for example, Patent Document 1 discloses an ant defense structure formed so that white ants do not enter the space under the floor. In this ant-proof structure, a barrier body is provided between the upper end of the rising portion of the foundation and the base of the building. The barrier body has a plate-like shape, and includes a foundation covering portion that covers the upper end of the foundation, and a pair of shielding walls that extend from the foundation covering portion downward on both sides of the foundation. The front end of the shielding wall is a free end and is separated from the foundation. Thus, the white ants that have risen up the rising portion of the foundation are blocked by the so-called rat return procedure, so that the white ants can be prevented from entering the underfloor space.

  However, the ant proof structure according to Patent Document 1 has a problem that air permeability in the underfloor space is poor because the rising part of the foundation and the base are sealed. On the other hand, white ants are allowed to enter when trying to ensure air permeability. In other words, it has been difficult to achieve both prevention of invasion of white ants in the underfloor space and ensuring air permeability in the underfloor space.

The present invention was devised in view of the above-described problems, and provides an insect repellent structure and an insect repellent construction method capable of preventing insects from entering the under floor space and ensuring air permeability of the under floor space.
