Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an ant-proof floor structure for a building, which comprises a sheet-like termite-proofing material stretched on the underside of a flooring material.

(Prior art and its problems) Many methods have been proposed to prevent termite damage. For example, there are structural measures to prevent intrusion by reducing the contact area between the foundation and the foundation surface, methods to inject, soak, or apply chemicals into the building components themselves, and even methods to apply chemicals into the soil around buildings and under floors. These include soil treatment methods such as injection and spraying. In recent years, it has also been implemented to kill termites by adding an insecticide to the sheet material. In the case of using this sheet material, the creation of so-called ant trails cannot be prevented unless the sheet material is stretched over the bottom surface of the flooring material without any gaps. This makes laying the sheet material difficult. Particularly in so-called unit-type buildings, a gap is created between the underfloor surface of the building and the foundation on which the unit is placed, so contact ant paths are likely to be created, and a sufficient termite prevention effect may not be achieved.

(Means for solving the problems) This invention was devised in view of the above problems.
A sheet-like termite-proofing material is stretched between the opposing sides of the joists constituting the flooring material, and the side ends of the termite-proofing material are suspended below the lower surface of the joists, so that the termite-proofing material avoids the area. Therefore, it covers the gap between the foundation and the floor and forms a repellent area across the entire underside of the floor.

(Example) The ant-proof floor structure of the present invention will be described in detail below based on the drawings.

The figure is a schematic cross-sectional view showing the ant-proof floor structure of the present invention. This termite-proof floor structure consists of a foundation 1, a foundation 2 placed on the top of the foundation 1, and a flooring material 3 attached via the foundation 2. The flooring material 3 includes a plurality of joists 31, 31... arranged in parallel at predetermined intervals, and the joists 31, 3.
A floor plate 32 is laid on top of the floor plate 1. Also flooring material 3
The required portions of the lower surface are supported by, for example, a large drawer 5 on the independent foundation 11.

In such a floor structure, between the adjacent joists 31 and 31 of the flooring material 3, and between the opposing sides 31a, 3
A sheet-like termite prevention material 4 is attached and stretched between 1a with nails or the like. This sheet-like termite prevention material 4 is made of a vinyl chloride resin material in the form of a sheet, and the inside thereof is impregnated with a termite repellent. Termite repellents are usually a mixture of highly emissive drugs such as crosvirofos, fenitrotin, and cyanphos, and long-lasting stabilizers such as zinc versatate.
The termite prevention material 4 is attached to both sides 31a, 31 of the joists 31, 31.
It is attached through nails or tassels between
It hangs downward.

As described above, the termite repellent material 4 forms the repellent area O by dispersing termite repellent around its surface.
Even if the termite-proofing materials 4, 4... stretched in this way are not continuous and create gaps H, H..., the repellent area O formed by each side edge 41, 41... covers each gap H, H... In this state, a continuous repellent region O is formed on the lower surface of the flooring 3.

On the other hand, in the case of the large puller 5, if a wide band-shaped termite prevention material 6 is placed on its upper surface, the gap H formed between the both side edges 61, 61 and the side edge 41 of the termite prevention material 4 will also be created by the repellent area O. It is covered and becomes continuous as a whole.

As described above, the termite-proof floor structure of the present invention continuously forms the repellent area on its lower surface, so that it prevents termites from forming contact paths as well as aerial termites, thereby keeping termites away.

(Effects) According to the above termite-proof floor structure, it is sufficient to install termite-proof material between the joists and let the side ends of this termite-proof material hang down below the bottom surface of the joists. It does not require continuous construction of termite-proofing materials, and is particularly suitable as a termite-proofing floor structure for unit-type buildings.
