[0020]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG.
The termite structure of the building A according to the embodiment includes, for example, a cloth foundation 1 constructed on an outer peripheral portion and a dirt floor 3 constructed on an embankment 2.
The termites 6 pass through the interior of the heat insulating material 5 closely attached to the outer side surface 4a of the rising portion 4 of the cloth foundation 1 of the building A without the underfloor space having A lower surface 5d of the heat insulating material 5
Further, a heat insulating material 8 is further attached via a stainless mesh (sheet material) 7 made of a corrosion-resistant material resistant to secretions of the termite 6, and two edges 7a, 7b are attached to the outer surface 8a and the inner surface 8b of the lower heat insulating material 8, respectively.

The cloth foundation 1 is constructed, for example, in a rectangular shape or the like in plan view on the outer peripheral portion of the building A. As shown in FIGS. It is formed in a T shape. An independent foundation or the like may be provided inside the cloth foundation 1 together with or instead of the cloth foundation 10 such as a partition foundation as in this embodiment.

The slab floor 3 is placed on the embankment 2 raised inside the cloth foundation 1 higher than the surrounding ground surface 11a, so that the top end face 1c of the cloth foundation 1 and the upper surface 3c thereof are almost at the same height. It has been constructed in. Note that a moisture-proof film, a heat insulating material, or the like may be laid on the embankment 2 instead of or together with the crushed gravel 12 as in this embodiment.

The heat insulating materials 5 and 8 are made of, for example, a synthetic resin foam or the like, and are in close contact with the outer surface 4a of the rising portion 4 via the stainless steel mesh 7 so as to be in two upper and lower stages. The upper heat insulating material 5 is formed by attaching a stainless steel mesh 7 to the lower heat insulating material 8 in advance by a fastening member such as a nail, a screw, a staple or the like, an adhesive, a heat welding, or the like, or by attaching the stainless steel mesh 7 at a building site. The mesh 7 may be mounted on the mesh 7 with an adhesive or an adhesive cement, or these two upper and lower heat insulating materials 5, 8
An integrated product formed by embedding a stainless steel mesh 7 in advance may be tightly attached to the outer surface 4a of the rising portion 4. Further, the stainless steel mesh 7 may be attached to the upper heat insulating material 5 in advance.

The heat insulating materials 5 and 8 may be adhered to the rising portion 4 after the fabric foundation 1 is applied, or when the above-described integrated material is used, the integrated material is disposed. The rising portion 4 or the like may be cast afterwards. In this embodiment, the upper and lower two-stage heat insulating materials 5, 8 are used.
Is adhered so as to be substantially the same height as the rising portion 4, but is not limited to this, and the heat insulating material 5,
The height, mounting position, and the like of 8 can be appropriately changed as needed. Further, when the stainless steel mesh 7 or the like is attached with a fixing member such as a nail, the fixing member may be made of, for example, copper, zinc, brass, or the like, if necessary, so as to avoid termites. The effect may be exhibited.

The termite 6 is an incompletely metamorphic insect living in a social life related to cockroaches, and is a generic term for the termite (Isoptera) Isoptera. Examples of such termites 6 include various termites such as Yamato termite and house termite. As shown in FIG. 3, the termite 6 has a non-deformable hard head 6a, while having a relatively soft and weak body 6b.

As shown in FIG. 4, the stainless steel mesh 7 is resistant to secretions of termites 6 and at least about 7
It has a plurality of stitches (anchor holes) 13 woven from stainless steel wire 7c or the like, which is a corrosion-resistant material having a Shore hardness of 0. As such a stainless mesh 7, for example, “termy mesh (TERM)
I-MESH) "(trade name, manufactured by Termymesh Australia) and the like.

The sheet material used as the termite barrier material is not limited to the stainless steel mesh 7, but is resistant to secretions such as formic acid released from the termites 6. Various materials are used as long as the material 6 has a hardness that cannot be chewed, 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.

Here, the sheet material is stainless steel mesh 7
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. In the case where the sheet material is not flexible, it may be manufactured in an appropriate shape in advance according to the shape of the portion 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 13, the upper and lower two-stage heat insulating materials 5,
When a sheet material is interposed between the sheets 8 or when one of the heat insulating materials 5 (8) is bonded or thermally welded in advance, the upper and lower portions of the sheet material are interposed by the anchor effect. There is an advantage that the two heat insulating materials 5, 8 or the heat insulating materials 5, 8 and the sheet material can be more firmly integrated. In addition, as the sheet material having a plurality of anchor holes, in addition to the stainless steel mesh 7, for example, a punching metal formed by punching out the anchor holes is exemplified.

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 6a of the termite 6 in at least one direction, the head 6a of the termite 6 passes through. The size is such that even if the head 6a does not pass through or the soft body 6b or the like contacts the anchor hole even if the head 6a passes through, and the white ants 6 dislike it, so that the white ants 6 can be prevented 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 7
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.

When the dimension 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, is applied to the sheet material. For example, the fine ants can prevent the white ants 6 from passing through. If the size of the anchor hole exceeds 3H, it is not preferable because the termites 6 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.

To improve the strength, crack resistance, adhesiveness, 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 may be applied after bonding or heat-welding the sheet material to the heat insulating materials 5 and 8, or when the sheet material is interposed between the two upper and lower heat insulating materials 5 and 8, You may adhere with a surface material.

As described above, if a sheet material such as a stainless steel mesh 7 is interposed between the upper and lower two heat insulating materials 5 and 8, the white ants 6 that have entered the lower heat insulating material 8 from the ground 11 can be advanced. Are blocked by this sheet material. Therefore, there is an advantage that the upper heat insulating material 5 can be protected from damage by the termites 6, and the termites 6 can be prevented from passing through the inside of the heat insulating material 5 and entering the shaft set B or the floor set C. Further, since the slab floor 3 is constructed on the embankment 2 inside the cloth foundation 1, there is an advantage that the termites 6 hardly invade from inside the cloth foundation 1.

Here, when the sheet material is located at a position higher than the ground surface 11a as in this embodiment, the upper heat insulating material 5 does not contact the ground 11, so that the upper heat insulating material 5
Can be more effectively protected.

The method of attaching the sheet material is not limited to this embodiment. For example, as shown in FIG. 5, the sheet material is formed so that the two edges 7a and 7b do not project sideways. Preferably, one of the two edges 7a and 7b of the sheet material is attached to, for example, the outer surface 8a or the inner surface 8b of the lower heat insulating material 8 as shown in FIGS. As a result, one of the two corners 14a and 14b on the upper surface 8c of the heat insulating material 8 and the upper surface 8c
It is desirable to cover the two corners 14a, 14b and the upper surface 8c in a U-shape in cross section, as shown in FIGS. That is, the corner 1
At 4a and 14b, there is a possibility that the white ants 6 which have progressed to the vicinity of the upper surface 8c inside the heat insulating material 8 may advance upward from these corners 14a and 14b, so that these corners 14a and 14b are If you cover with wood,
There is an advantage that this wraparound of the termites 6 can be prevented.

The edge 7 such as the stainless steel mesh 7
a and 7b may be attached to only the upper heat insulating material 5 in addition to the case where they are attached only to the lower heat insulating material 8, or may be attached to the upper and lower two heat insulating materials 5 and 8 as shown in FIG. Is also good.

As shown in FIG. 9, in the termite protection structure of the building A according to the second embodiment, in the first embodiment, the inner edge 7b of the stainless steel mesh 7 is formed longer, The edge 7b is embedded in the rising portion 4.

By embedding the edge portion 7b in the rising portion 4 in this manner, even if a gap is formed between the lower heat insulating material 8 and the rising portion 4, the upper heat insulating material is removed from the gap. There is an advantage that the termites 6 can be prevented from entering the material 5.

Also in this case, in order to prevent the white ants 6 from turning around from the corners 14a on the outer surface 8a side of the lower heat insulating material 8, as in this embodiment, the outside of the stainless mesh 7 or the like is required. The upper edge 7a is divided into two upper and lower insulating materials 5, 8
It is desirable to attach it to any one of the outer surfaces 5a (8a).

As shown in FIG. 10 and FIG. 11, the termite structure of the building A according to the third embodiment is different from the first embodiment in that the lower heat insulating material 5 formed lower and the lower heat insulating material 5 formed higher. The heat insulating material 8 is the inner surface 4b of the rising portion 4.
And the two upper and lower insulation materials 5, 8
Inner edge 7 of stainless steel mesh 7 interposed between
b is formed longer, and the edge 7b is buried in the interstitial floor 3.

If the edge 7b is buried in the floor 3 in this way, the termites 6 enter the upper insulation 5 from the joint 15 between the lower insulation 8 and the floor 3. There is an advantage that it can be prevented.

Here, when the sheet material is located at a position higher than the lower surface 3d of the earth floor 3 as in this embodiment, the heat insulating material 5 in the upper stage does not come into contact with the embankment 2 or the crushed gravel 12, and so on. There is an advantage that the upper heat insulating material 5 can be protected more effectively.

In the first to third embodiments described above,
Although the case where the heat insulating materials 5 and 8 are in close contact with either the outer surface 4a or the inner surface 4b of the rising portion 4 has been described, the present invention is not limited to this, and as shown in FIG. It may be in close contact with both side surfaces 4a and 4b of the part 4, respectively.

In this case, similarly to the above, the outer edge 7a such as the stainless steel mesh 7 on the inner surface 4b side of the rising portion 4 may be embedded in the rising portion 4.

The termites 6 are prevented from entering from above or below the spliced portion 16 of the spliced portion 16 between the cloth foundation 10 or the like provided inside the cloth foundation 1 and the floor 3. For this purpose, it is desirable to attach a sheet material so as to close the spliced portion 16.

As shown in FIGS. 13 and 14, the termite-proof structure of the building A according to the fourth embodiment is, for example, a heat insulating material 5 closely attached to the outer surface 20a of the foundation slab 20 of the building A having no underfloor space. And physically prevents the white ants 6 from passing through the inside and into the frame B and the floor set C installed on the base slab 20.
d, a heat insulating material 8 through the stainless steel mesh 7
The two edges 7a and 7b of the stainless mesh 7 are attached to the outer surface 8a and the inner surface 8b of the lower heat insulating material 8, respectively.

The base slab 20 is formed so that the portion on which the base 21 and the like are mounted is formed thicker than other portions. However, the configuration of the base slab 20 is not particularly limited. Various configurations in which B and floor set C can be directly installed can be adopted. Also, this basic slab 2
In a predetermined range below 0, a heat insulating material may be laid as needed.

As described above, in the base slab 20, similarly to the case of the cloth base 1, if the sheet material such as the stainless steel mesh 7 is interposed between the upper and lower heat insulating materials 5 and 8,
The upper heat insulating material 5 can be protected from damage by the termites 6, and the termites 6 pass through the inside of the heat insulating material 5 so that the frame B and the floor
There is an advantage that it can be prevented from invading.

As described above, also in this embodiment, the inner edge 7b of the stainless steel mesh 7 or the like is formed longer, and this edge 7b is embedded in the base slab 20. Even if a gap is formed between the lower heat insulating material 8 and the base slab 20, there is an advantage that the termites 6 can be prevented from entering the upper heat insulating material 5 from this gap.

Further, when the sheet material is at a position higher than the ground surface 11a as in this embodiment, the upper heat insulating material 5 does not contact the ground 11, so that the upper heat insulating material 5 can be more effectively used. There is an advantage that can be protected.

[0053]

As described above, according to the first and third aspects of the present invention, in a building without a underfloor space having a cloth foundation and a slab floor, the lower surface of the upper heat insulating material is further interposed with a sheet material. Since the lower heat insulating material is attached, the advance of termites that have entered the lower heat insulating material from the ground is prevented by the sheet material. For this reason, there is an advantage that the upper heat insulating material can be protected from damage by termites, and the termites can be prevented from passing through the inside of the heat insulating material and invading the shaft and floor. In addition, since the earth floor is constructed on the embankment inside the cloth foundation, there is an advantage that it is difficult for termites to invade from inside the cloth foundation.

According to the second and fifth aspects of the present invention, the outer or inner edge of the sheet material is buried in the rising portion. Even when a gap is formed, there is an advantage that termites can be prevented from entering the upper heat insulating material from the gap.

According to the fourth aspect of the present invention, since the sheet material is located at a position higher than the lower surface of the clay floor, the upper heat insulating material does not come into contact with the embankment, the crushed gravel or the like. Therefore, there is an advantage that the upper heat insulating material can be protected more effectively.

According to the sixth aspect of the present invention, the inner edge of the sheet material is buried in the interstitial floor, so that the upper heat insulating material extends from the joint between the lower insulating material and the interstitial floor. There is an advantage that termites can be prevented from invading to the like.

According to the seventh aspect of the present invention, in a building having no underfloor space in which a frame and a floor are installed on a foundation slab, a lower heat insulating material is further provided on the lower surface of the upper heat insulating material via a sheet material. Since the material is attached, the heat insulating material in the upper stage can be protected from damage by termites as in the case of the first and third aspects, and the termites pass through the inside of the heat insulating material and enter the shaft and floor frames. This has the advantage that it can be prevented.

According to the eighth aspect of the present invention, since the inner edge of the sheet material is embedded in the base slab, a gap is formed between the lower heat insulating material and the base slab. However, there is an advantage that termites can be prevented from entering the upper heat insulating material from this gap.

According to the ninth aspect of the present invention, since the sheet material is at a position higher than the ground surface, the upper heat insulating material does not contact the ground. Therefore, there is an advantage that the upper heat insulating material can be protected more effectively.

According to the tenth aspect of the present invention, at least one of the two edges of the sheet material is attached to the side surface of one of the upper and lower two-stage heat insulating materials. There is an advantage that white ants can be prevented from flowing upward from a corner on the upper surface of the heat insulating material.

According to the eleventh aspect of the present invention, since the sheet material has flexibility, shaping or the like at a construction site is possible, and therefore, when the sheet material is attached at the construction site, construction is easy. There is an advantage.

According to the twelfth aspect of the present invention, since the sheet material has a plurality of anchor holes having a dimension not more than twice the maximum dimension of the cross section of the head of the termite in at least one direction, When the sheet material is interposed between the upper and lower two-stage heat insulating materials, or when the sheet material is previously bonded or thermally welded to one of the heat insulating materials, the sheet material is interposed by the anchor effect. There is an advantage that the upper and lower two-stage heat insulating materials or the heat insulating material and the sheet material can be more firmly integrated. Further, the size of the anchor hole is not more than twice the maximum size, and the head of the termite does not pass through, or a soft body or the like comes into contact with the anchor hole even if the head passes, and the termite is used. Dislike it,
Termites can be prevented from passing through the sheet material. 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.
