[0019]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG.
The termite-prevention structure of the building A according to the embodiment is such that, for example, the white ants 4 pass through the inside of the heat insulating material 3 which is in close contact with the outer surface 2a of the rising portion 2 of the cloth foundation 1 constructed on the outer peripheral portion of the building A. For physically preventing the intrusion into the frame B and the floor C, the upper surface 3c of the heat insulating material 3 is made of a corrosion-resistant material resistant to secretions of the termites 4, for example. The stainless steel mesh (sheet material) 5 is covered, and two edges 5 a and 5 b of the stainless steel mesh 5 are attached to the outer side surface 3 a and the inner side surface 3 b of the heat insulating material 3, respectively.

The cloth foundation 1 is constructed in a rectangular shape or the like in plan view on the outer peripheral portion of the building A. As shown in FIG. 1 and FIG. It is formed in a T shape.

The heat insulating material 3 is made of, for example, a synthetic resin foam or the like, and is in close contact with the outer surface 2 a of the rising portion 2. The heat insulating material 3 may be adhered to the rising portion 2 after the cloth foundation 1 is constructed, or the rising portion 2 or the like may be cast after the heat insulating material 3 is arranged. Further, in this embodiment, the heat insulating material 3 and the rising portion 2 are formed at substantially the same height. However, the present invention is not limited to this. It can be changed as appropriate.

The termites 4 are imperfectly metamorphic insects that live close to cockroaches and are a general term for the termite (Isoptera) Isoptera. Examples of such termites 4 include various termites such as Yamato termite and house termite. Further, as shown in FIG. 3, the termite 4 has a non-deformable hard head 4a, but has a relatively soft and weak body 4b.

As shown in FIG. 4, the stainless steel mesh 5 is resistant to secretions of termites 4 and has at least about 7
It has a plurality of stitches (anchor holes) 7 woven from a stainless steel wire 5c, which is a corrosion resistant material having a Shore hardness of 0. As such a stainless mesh 5, for example, “termy mesh (TERMI mesh)
-MESH) "(trade name, made by Termymesh Australia) and the like.

The sheet material used as the termite barrier material is not limited to the stainless steel mesh 5, but is resistant to secretions such as formic acid released from the termites 4 and is a termite. Various materials are used as long as the material 4 has a hardness that cannot be crushed, preferably a Shore hardness of at least about 70, and is made of a corrosion-resistant material having a service life of several tens of years in a use environment. be able to. Examples of such a sheet material include a sheet or nonwoven fabric woven or knitted from fibers, filaments, strands, or the like of ceramics, glass, synthetic resin, and the like, a metal plate, a metal sheet, and the like.

The sheet material such as the stainless steel mesh 5 is attached to the heat insulating material 3 in advance at a factory or the like by a fastening member such as a nail, a screw, a staple or the like, an adhesive, heat welding, or the like. Installed on site. When the sheet material is attached with a fastening member such as a nail, the fastening member may be made of, for example, copper, zinc, brass, or the like as necessary, or may contain a termite repellent effect. You may make it show.

Here, the sheet material is stainless steel mesh 5
In the case where the sheet material has flexibility as described above, shaping or the like can be performed at a construction site, and therefore, there is an advantage that construction when attaching the sheet material at the construction site is simple. If the sheet does not have flexibility, it may be manufactured in an appropriate shape in advance according to the shape of a predetermined portion of the heat insulating material 3 to which the sheet material is to be attached by factory production or the like.

In the case where the sheet material has a plurality of anchor holes such as the stitches 7, when the sheet material is bonded or thermally welded to the heat insulating material 3, they can be more firmly integrated by the anchor effect. There is an advantage. In addition, as the sheet material having a plurality of anchor holes, in addition to the stainless steel mesh 5, for example, a punching metal formed by punching out the anchor holes and the like can be mentioned.

In this case, when the size of the anchor hole is not more than twice the maximum dimension H of the cross section of the head 4a of the termite 4 in at least one direction, the head 4a of the termite 4 passes through. The size is such that even if the head 4a does not pass through or the soft body 4b or the like comes into contact with the anchor hole, and the termites 4 dislike it, it is possible to prevent the termites 4 from passing through the sheet material. it can. Further, since the size of the anchor hole can be made relatively large, there is an advantage that the material cost of the sheet material can be reduced, and the dimensional accuracy may be low, so that the manufacture is simple.

The maximum dimension H is, for example, about 1.1 to 1.25 mm for house termites and about 1.0 to 1.2 mm for house termites. In this case, it is desirable that the size of the anchor hole is set to about 2.4 mm or less in at least one direction. The shape of the anchor hole is not particularly limited, and may be an appropriate shape such as a rectangular shape or a circular shape. In short, the dimension of the anchor hole may be 2H or less in any one direction or two or more directions.

Here, the sheet material is stainless steel mesh 5
In the case of a mesh-like member, the number of fibers, filaments, strands, and the like can be reduced, so that there is an advantage that cost can be more effectively reduced.

If the size of the anchor hole is more than 2H but not more than 3H, a surface material containing at least cement and fine aggregate, such as mortar or adhesive cement, should be applied to the sheet material. In this case, the fine ants and the like can prevent the white ants 4 from passing through. If the size of the anchor hole exceeds 3H, it is not preferable because the termites 4 may pass through even if the surface material is applied. In addition, even if it is 2H or less, a surface material may be applied.

In order to improve strength, crack resistance, adhesion, water tightness, abrasion resistance, etc., a polymer such as a cement adhesive contained in the adhesive cement is added to the surface material. Preferably, a termite repellent such as zinc or copper, or a zinc compound or a copper compound may be added as necessary. This surface material is a heat insulating material 3
The sheet material may be applied after being integrated by bonding or heat welding or the like, or the sheet material may be bonded to the heat insulating material 3 with this surface material.

As described above, at least the upper surface 3 of the heat insulating material 3
If c is covered with a sheet material such as stainless steel mesh 5 or the like, the white ants 4 that have entered the heat insulating material 3 from the ground 8 or the like pass through the inside of the heat insulating material 3 and penetrate into the shaft set B or the floor set C. This has the advantage that it can be prevented.

The coverage of the sheet material is not limited to this embodiment. For example, as shown in FIG. 5, only the upper surface 3c of the heat insulating material 3 may be covered, but it is preferable. As shown in FIGS. 6 and 7, one of the two edges 5 a and 5 b of the sheet material is attached to the outer side surface 3 a or the inner side surface 3 b of the heat insulating material 3 so that the heat insulating material 3
Either one of the two corners 9a and 9b on the upper surface 3c and the upper surface 3c are formed in an L-shaped cross section, more preferably FIG.
As shown in FIG. 2, it is preferable that the two corners 9a and 9b and the upper surface 3c be covered in a U-shaped cross section. That is, in the corners 9a and 9b, the inside of the heat insulating material 3 is
There is a possibility that the termites 4 that have progressed to the vicinity of c may travel upward from these corners 9a and 9b, so if these corners 9a and 9b are covered with a sheet material, There is an advantage that wraparound can be prevented.

In this building A, on the ground surface 8a inside the cloth foundation 1 for the purpose of, for example, moisture-proofing the underfloor space 10 formed inside the cloth foundation 1,
As in this embodiment, a moisture-proof sheet 11 may be laid as needed, and a pressing layer 12 of, for example, a dump container, dry sand, dry gravel, etc. may be provided thereon.

As shown in FIG. 8, in the termite protection structure of the building A according to the second embodiment, in the first embodiment, the edge 5b of the stainless steel mesh 5 on the rising portion 2 side is formed longer. The edge 5b is sandwiched under an airtight packing 14 interposed between the rising portion 2 and the base 13 placed on the rising portion 2.

By fixing the edge 5b on the rising portion 2 in this manner, even if a gap is formed between the heat insulating material 3 and the rising portion 2, the frame B or There is an advantage that the termites 4 can be prevented from entering the floor set C.

In this case, as shown in FIG. 9, only the upper surface 3c of the heat insulating material 3 may be covered with a stainless steel mesh 5 or the like, but the corner 9a on the outer surface 3a side of the heat insulating material 3 may be used.
In order to prevent the white ants 4 from wrapping around, as in this embodiment, the other edge 5a of the stainless steel mesh 5 or the like is attached to the outer side surface 3a of the heat insulating material 3 to cover this corner 9a. It is desirable to keep.

As the hermetic packing 14, various known structures can be used.
May be sandwiched under the edge 5b.
As shown in FIG. 10, the corners 9 a and the upper surface 3 c on the outer surface 3 a side of the heat insulating material 3 are covered with a stainless mesh 5 or the like, and an edge 5 b such as the stainless mesh 5 sandwiched under the airtight packing 14. Is further bent along the corner 15b on the inner surface 2a side of the rising portion 2, for example,
A U-shaped stainless mesh 5 or the like having a U-shaped cross section having an opening having substantially the same width as the sum of the thicknesses of the rising portion 2 and the heat insulating material 3 is prepared in advance. And so on from above,
There is an advantage that the positioning of the sheet material such as the stainless mesh 5 or the like is easy and the displacement until fixing is prevented.

Further, the means for fixing the edge portion 5b is not limited to this embodiment. Instead of sandwiching the edge portion 5b under the hermetic packing 14, concrete is cast and installed. It may be embedded in the section 2. In this case as well, even if a gap is formed between the heat insulating material 3 and the rising portion 2, it is possible to prevent the termites 4 from entering the shaft set B or the floor set C from this gap. . Here, as shown in FIG. 11, when the edge 5b is buried in the mortar 16 which is to be constructed at the top end of the rising portion 2, the heat insulating material 3 is arranged and then the rising portion 2 is struck. In addition to the installation procedure, after installing the fabric foundation 1,

Further, as shown in FIG. 15, it may be in close contact with the inner surface 21 b of the rising portion 21, or may be in close contact with both the outer surface 21 a and the inner surface 21 b of the rising portion 21.

Further, the configuration of the solid foundation is not particularly limited, and as shown in FIGS. 16 to 18, for example, a solid foundation 25 having a foundation slab 24 whose outer peripheral portion is not thickened. In this case, the heat insulating material 3 may be similarly adhered to one or both of the outer surface 21a and the inner surface 21b of the rising portion 21.

14 and 15 are provided inside the rising portions 21 of the solid foundations 23 and 25.
16 to 18, or a predetermined portion of the base slab 24 may be formed thicker than other portions as necessary, as shown in FIGS. For example, a columnar body 27 or the like formed in a columnar shape or the like can be provided upright at the portion.

As described above, the solid foundations 23 and 25 have at least the upper surface 3 of the heat insulating material 3 as in the case of the cloth foundation 1.
