Description

[Detailed Description of the Invention] The present invention relates to the structure of a termite-proof floor that protects buildings from damage caused by the wood-eating nature of termites.

Due to the wood-eating nature of termites, so-called damp wood is damaged by termites, which often causes damage such as deteriorating the durability of wooden buildings and eventually causing the buildings themselves to collapse. The damage caused by termites' wood-eating habit begins in dark areas such as under floors and inside siding, so in the early stages it is hardly exposed to the outside, but it is often noticed when the damage has progressed to the entire building. It is not easy to modify or repair.

Conventional methods for preventing termite damage include structural methods, chemical treatment methods for wood, and soil treatment methods.

The structural method is to prevent termites from directly entering the building, by reducing the contact area between the underside of the foundation and the foundation surface, and by installing metal plates such as dovetails to prevent termites from entering from the ground. In addition, the main methods include concrete pounding of the underground ground, including inubashiri.

On the other hand, the wood termite treatment method involves injecting, dipping, or spraying wood with a termiticide to prevent the wood itself from being eaten by termites.

The soil treatment method is a method of injecting, mixing, or spraying liquid or powder into the soil in contact with buildings to prevent soil from entering buildings.

According to these above-mentioned methods, since the focus is on special construction at the site, there are large variations in construction, the construction period is long, and there are problems in terms of construction costs. Moreover, when using chemical solutions, it has been pointed out that residual pollution and chemical damage to surrounding areas due to diffusion into the soil are a major problem.

The present invention was developed in view of the above-mentioned problems.If an anti-termite material is placed on the bottom surface of the floor panels constituting the floor in advance, and the floor structure is constructed by laying these floor panels, the floor This provides an extremely simple, safe, and effective structure for an ant-proof floor in which an ant-proof layer is formed over the entire lower surface.

Hereinafter, the structure of the ant-proof floor according to the present invention will be explained in detail based on the drawings.

FIG. 1 is a perspective view of a floor panel 1 that constitutes a building floor.

The floor panel 1 is constructed by assembling frame materials 11, 11, . On the other hand, an anti-termite material 2 is stretched on the lower surface using adhesive, nails, or the like.

This anti-termite material 2 is located on the lower surface side of the floor panel 1, and is therefore preferably a sheet material that can also block moisture from under the floor.

As a specific example, a moisture-proof sheet material such as polyethylene impregnated with an anti-termite chemical solution is pasted on the surface of plywood stretched on the lower surface.

Moreover, the termite-proof material 2 can be installed on the underside of the floor panel 1 in advance at the factory where the floor panel 1 is manufactured, but it can also be installed at the site immediately before the floor panel 1 is laid. good.

In addition, as the chemical solution impregnated into the termite prevention material 2, chlordane, chlorpirios, permethrin, etc. are usually used.

A case where a floor is constructed on the foundation of a building using the floor panel 1 constructed as described above will be explained using the partially omitted sectional view of FIG. 2.

The foundations 3, 3... are made of concrete and consist of a footing 31 and a foundation part 32, and are independent foundations or cloth foundations.

The floor panels 1, 1... are laid on the upper surfaces of the foundations 3, 3... through the installation of architraves, etc., so as to butt each other. Then, wall panels 4, 4... are erected at required locations on the floor panels 1, 1....

In the floor structure of the building of the present invention, when the floor panels 1, 1... are laid between the foundations 3, 3..., the termite-proofing materials 2, 2... constitute one termite-proofing layer over the entire lower surface. become.

Therefore, even if the termites living in the soil G in the subfloor reach the lower surface of the floor panel 1 through the foundation parts 32, 32..., the termite-proof layer 21 will cover the entire lower surface of the floor panel 1, 1... Therefore, termites cannot enter into the floor panel 1 through this anti-termite layer 21.

Since the termite layer 21 is impregnated with a chemical solution that kills or exterminates termites as described above, the termites that have ascended along the base portions 32, 32, etc. are impregnated with the chemical solution of the termite layer 21. It will be exterminated.

Therefore, with the floor structure of the present invention, even if termites are present in the soil G under the floor or have invaded, the termites will not cause feeding damage from the underside of the floor. In particular, termites themselves often live in dark areas with poor ventilation, such as under floors, so providing an anti-termite layer 21 on the underside of the floor is an extremely effective means of preventing termites.

In order to integrally form this anti-termite layer 21 over the entire area under the floor, the lower half of the outer surface of the frame members 11, 11... of the floor panel 1 may be coated and impregnated with a similar chemical solution or agent. , termites do not invade the abutting surfaces of the floor panels 1, 1, and a complete termite prevention effect can be obtained.

In addition, by applying anti-termite treatment to the floorboards of architraves, etc., these boards themselves will not be damaged by termites.
The entire floor structure is a complete, termite-proof structure.

As explained above, the structure of the anti-termite floor of the present invention is that the anti-termite material is pre-strung on the bottom surface of the floor panel.
If this floor panel is laid to form a floor, an anti-termite layer will be formed on the entire underside of the floor at the same time, and the anti-termite effect will be great and the construction will be simple. Furthermore, if these anti-termite layers are applied in advance to the bottom surface of the floor panel 1 by a factory or the like, the quality will be even more stable and the structure will be optimal for mass production. Furthermore, the cost of anti-termite construction is lower than ever before, and it is extremely safe with no chemical damage.

Claims (1)

[Scope of Claim for Utility Model Registration] In a floor structure in which a plurality of floor panels are laid on a foundation, the floor panels are constructed of frame materials in a substantially rectangular shape, and plywood is stretched on the upper and lower surfaces of the frame material, and A termite- and moisture-proof sheet material impregnated with an anti-termite chemical solution is pasted on the plywood surface, and by laying each of the floor panels abutting each other on the foundation, the entire bottom surface of the floor is coated. The structure of an ant-proof floor is characterized in that an ant-proof layer is formed over a period of time.
