Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG.
The termite-proof structure of the building A according to the embodiment is, for example, from the ground surface 2 inside the cloth foundation 1 constructed on the outer peripheral portion of the building A.
The termite 3 is the inner surface 4 of the rising portion 4 of the cloth foundation 1.
b to physically prevent entry into the frame B and the floor set C such that the termite sheet 5 is exposed in the underfloor space 6 formed inside the cloth foundation 1. And projecting inward from the rising portion 4 and the ground surface 2
From the lower surface of the termite-control sheet 5 when the termite-control sheet 5 is fixed to the rise section 4 on the exposed surface 7 of the termite-control sheet 5 to the underfloor space 6 from the lower end of the termite-control sheet 5. And the sum of the shortest distance to the upper surface side of the fixing case 8 via the above at least 1 m is 1 m or more.

The cloth foundation 1 is constructed on the outer peripheral portion of the building A in, for example, a rectangular shape in a plan view, and as shown in FIG. 1 and FIG. It is formed in a T shape.

The underfloor space 6 is formed between the ground surface 2 inside the cloth foundation 1 and the floor set C. For example, a cloth foundation such as a partition foundation provided inside the cloth foundation 1 is provided. (Basic) 1
It is divided into a plurality by 0. Note that the inside of the cloth foundation 1 is not limited to the case where the cloth foundation 10 partitions the plurality of underfloor spaces 6 as in this embodiment, but one underfloor formed only by the cloth foundation 1 in the outer peripheral portion. In the space 6, an independent foundation such as a bundle foundation, a slab stone or the like may be provided. Alternatively, a plurality of under-floor spaces 6 may be partitioned by the cloth foundation 10, and an independent foundation, a bunch of stones, and the like may be further provided inside.

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

The termite sheet 5 is made of a corrosion-resistant material that is resistant to secretions of the termites 3. As such a termite sheet 5, for example, as shown in FIG.
Woven from stainless steel wire 11 or the like, which is a corrosion-resistant material having a Shore hardness of at least about 70, and having a Shore hardness of at least about 70, and not more than twice the maximum dimension H in the cross section of the head 3a of the termite 3. And a stainless mesh 13 having a plurality of stitches (vent holes) 12. As the stainless steel mesh 13, for example, “TERMI-MESH”
(Trade name, manufactured by Termymesh Australia) and the like can be suitably used.

The termite sheet 5 used as a termite barrier material is not limited to the stainless steel mesh 13, but is resistant to secretions such as formic acid released from the termites 3. Is composed of a corrosion resistant material having a hardness that cannot be chewed, preferably a Shore hardness of at least about 70, or an impact strength that cannot be chewed, and which has a service life of several tens of years under the use environment. If so, various things can be used. Examples of the termite sheet 5 include a sheet or nonwoven fabric woven or knitted from fibers, filaments, strands, or the like of ceramics, glass, synthetic resin, metal, or the like, or a metal plate, a metal sheet, or a synthetic resin sheet. And a rubber sheet.

Here, the termite control sheet 5 is
In the case of having a plurality of vents, the termites 3 can make the termites 3 sense the space or the ventilation in the vents that the termites 3 do not like so much, so that there is an advantage that the intrusion of the termites 3 can be more effectively prevented. is there. In addition, the size of the ventilation hole is such that the head 3a of the termite 3 in any direction.
If the maximum dimension H is not more than twice the maximum dimension H in the cross section, the head 3a of the termite 3 does not pass through the ventilation hole, or the soft body 3b or the like contacts the ventilation hole even if the head 3a passes. Since the termites 3 dislike the size, there is an advantage that the termites 3 can be surely prevented from passing through the ventilation holes. Further, since the size of the ventilation hole can be made relatively large, there is an advantage that the material cost of the termite control sheet 5 can be reduced, and the dimensional accuracy can 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 ventilation hole is set to about 2.4 mm or less in at least one of the directions. The shape of the ventilation hole is not particularly limited, and may be an appropriate shape such as a rectangular shape or a circular shape. In short, the size of the vent hole is one direction,
Alternatively, it may be 2H or less in two or more directions.

When the termite sheet 5 is a mesh member such as a stainless steel mesh 13, the number of fibers, filaments, strands and the like can be reduced, so that the cost can be reduced more effectively. There is an advantage.

Further, a termite sheet 5 having a plurality of ventilation holes
Other than the stainless mesh 13 having the plurality of stitches 12, a punching metal formed by punching a plurality of ventilation holes, or a metal or synthetic resin having a ventilation hole formed by a plurality of shearing grooves, for example. And the like.

In addition, when the termite control sheet 5 is made of a flexible material such as the stainless steel mesh 13, shaping at the construction site of the building A is possible, so that the construction is easy. There is an advantage that is. In the case of not having flexibility, the termite sheet 5 may be manufactured into an appropriate shape in advance according to the shape of the portion where the termite-control sheet 5 is to be constructed by factory production or the like.

As shown in FIG. 2, the termite-control sheet 5 constructed as described above has, for example, an airtight packing or the like interposed between the rising portion 4 and the base 14 placed on the rising portion 4. The outer edge portion 5 a is sandwiched under the spacer 15 so as to protrude inward of the rising portion 4.

A predetermined range including the tip 5b of the termite control sheet 5 is vertically supported by the tip of a projection 16 projecting a predetermined length from the fixed portion 8 to the underfloor space 6 when fixed to the rising portion 4. The section 17 is provided. That is, the exposed surface 7 of the termite control sheet 5 to the underfloor space 6 includes the upper surface 16 c and the lower surface 16 d of the projecting portion 16 and the outer surface 17 of the vertical portion 17.
a and the inner surface 17b. The shortest distance of the exposed surface 7 from the lower surface side of the fixing term 8 to the upper surface side of the fixing term 8 via the tip 5b of the termite control sheet 5 can be ignored because the thickness of the termite controlling sheet 5 is small. For example, the sum of the length L2 of the protruding portion 16 and the height L3 of the vertical portion 17 is 2
Times (= L2 + L3 + L3 + L2).

Here, when the termites 3 enter the underfloor space 6 from the ground surface 2 and attempt to invade the frame B such as the base 14 by climbing the inner side surface 4b of the rising portion 4, the termites 3 First, it is necessary to climb the inner side surface 4b of the rising portion 4 to the top end 4c. Top end 4c of rising section 4
In order to further advance the termite 3, the lower surface 16 d of the projecting portion 16, the outer surface 17 a and the inner surface 17 b of the vertical portion 17, and the upper surface 16 c of the projecting portion 16 You need to walk sequentially.

In this case, the height L1 from the ground surface 2 to the top end 4c of the rising portion 4 and the lower surface side of the fixing surface 8 on the exposed surface 7 via the tip 5b of the termite control sheet 5 The shortest distance to the top side of edge 8

(Equation 1) Sum with

(Equation 2) Is 1 m which is considered to be the walking distance of termite 3
As described above, the termite 3 cannot reach the base 14 or the like. Therefore, there is an advantage that the termites 3 can reliably be prevented from climbing the inner side surface 4b of the rising portion 4 and entering the shaft assembly B or the floor assembly C.

Here, for example, L1 = 40 (cm), L
When 2 = 5 (cm) and L3 = 35 (cm),
The sum is approximately (40 + 2 × 5 + 2 × 35 =) 120
(Cm). The sum is preferably 1.2 m or more, more preferably 1.4 m or more.

If a vertical portion 17 is provided at a predetermined position of the termite control sheet 5 as in this embodiment, the termites 3 need to climb up and down in the vertical portion 17. There is an advantage that the walking can be made more difficult. In this case, it is more effective if the height of the vertical portion 17 is 20 cm or more, preferably 30 cm or more.

The number of the vertical portions 17 is not limited to one, and two or more vertical portions 17 may be provided as shown in FIG. 5 in order to more effectively hinder the walking of the termite 3. . Further, as shown in FIG. 6, the vertical portion 17 may be supported vertically upward. Further, as shown in FIG. 7, two or more portions supported in the horizontal direction or the like may be formed in addition to the vertical portion 17.

In short, the sum should be 1 m or more, and the shape of the termite sheet 5 is not particularly limited. For example, when the vertical portion 17 is not provided, as shown in FIG. 8, the termite control sheet 5 may be simply provided in a horizontal direction or the like.

The fixing position of the termite control sheet 5 is not particularly limited. As shown in FIGS. 6 and 7, nails, screws, staples and the like are set at a predetermined height on the inner surface 4b of the rising portion 4. It may be fixed with a fixing member or the like, or further bonded with mortar, adhesive cement, or the like. Alternatively, it can be buried in the concrete when the rising portion 4 is cast,
The mortar may be buried in the mortar to be installed on the top end 4 c of the rising portion 4.

Here, as in the example shown in FIG. 6, a termite repellent part 1 containing a termite repellent such as copper or zinc at the tip 5b of the termite-preventing sheet 5 or the like.
Providing the projections 8 has an advantage that the termites 3 can be prevented from moving forward from the termite repellent portions 18. The same effect can be obtained when a plurality of termite repellent tapes 19 containing termite repellent material are attached to the exposed surface 7 in parallel with the circumferential direction of the termite repelling sheet 5 and at an interval from each other.

Similarly, the termite repellent sheet 5 itself may contain a termite repellent, or the termite repellent sheet 5 may be made of a termite repellent. Further, the exposed surface 7 may be coated with a termite repellent such as hinokitiol, a salt of copper or zinc, or boric acid.

The exposed surface 7 may be mirror-finished by mirror polishing or the like, or the exposed surface 7 may be covered with a surface material that reduces the walking frictional resistance of the termite 3 by coating a synthetic resin or wrapping a synthetic resin film. If so, there is an advantage that the termites 3 are difficult to walk.

When a cloth foundation 10 such as a partition foundation is provided inside the cloth foundation 1, as shown in FIG. It is desirable that the termite sheets 5 be provided in a protruding manner,
In this case, the height from the ground surface 2 to the top end 10c of the fabric base 10 and the lower surface of the termite sheet 5 exposed to the underfloor space 6 from the lower surface side of the fixing base 8 to the fabric base 10 At the time of fixing 8 through the tip 5b of the dovetail sheet 5
The sum with the shortest distance to the upper surface of the cloth base 10 may be set to 1 m or more on both sides of the cloth foundation 10.

The termite sheet 5 may be fixed by sandwiching the central portion in the width direction below the spacer 15 as in this embodiment, or separate termite sheets 5 from both sides of the cloth base 10. May be fixed at a predetermined height.

Similarly, when an independent foundation such as a bundling foundation or a bracelet is provided, an anti-termite sheet 5 is protruded around the independent foundation or the bracelet, and the independent foundation or the bracelet is separated from the ground surface 2. And the shortest distance from the lower surface side of the exposed surface 7 when fixed to the independent foundation or slab to the upper surface side when fixed via the outer peripheral edge of the termite sheet 5. The sum should be 1 m or more.

In this way, if the cloth foundation 10, the foundation such as the independent foundation, and the slab are constructed as described above, the termites 3 can be mounted on the foundation 14 or the slab, , Cannot reach the floor assembly such as the floor bundle. Therefore, there is an advantage that the termites 3 can be reliably prevented from climbing the foundation or slab and entering the frame B or the floor C.

Further, when the piping pipe 20 is provided, similarly, the termite-control sheet 5 is fixed to the outer peripheral surface 20a of the piping pipe 20 exposed in the underfloor space 6 by clamping or using an adhesive. At the same time, the height of the exposed surface 21 of the pipe pipe 20 to the underfloor space 6 from the lower end 21d to the upper end 21c, and the termite sheet 5 If the sum of the shortest distance to the upper surface side of the fixing case 8 through the outer peripheral edge 5e is set to 1 m or more, it is ensured that the termites 3 climb the piping pipe 20 and enter the floor set C or the shaft set B. There is an advantage that can be prevented.

On the ground surface 2, a moisture-proof sheet is laid as necessary for the purpose of, for example, moisture-proofing the underfloor space 6.
A holding layer of dry gravel or the like may be provided, or an interstitial floor or the like may be constructed as necessary.

As shown in FIGS. 9 and 10, the termite-proof structure of the building A according to the second embodiment includes, for example, an outer peripheral rising portion 32 and a foundation slab 33 constructed on the outer peripheral portion of the solid foundation 31 of the building A. From terminating part 34, termite 3
Is physically prevented from climbing the inner side surface 32b of the outer peripheral rising portion 32 and entering the shaft set B and the floor set C. The termite control sheet 5 is placed inside the outer peripheral rising portion 32. A projection from the upper surface 33c of the base slab 33 to a top end 32c of the outer periphery rising portion 32, while projecting inward from the outer periphery rising portion 32 so as to be exposed in the formed at least one underfloor space 6; The shortest distance from the lower surface of the termite-control sheet 5 to the exposed surface 7 of the underfloor space 6 with respect to the outer periphery rising portion 32 through the tip 5b of the termite-control sheet 5 to the upper surface of the termite-control sheet 8 The sum with the distance is 1 m or more.

The termite sheet 5 is provided inwardly of the outer peripheral rising portion 32 in the same manner as in the first embodiment. In other words, if the termite sheet 5 is constructed as described above, the termites 3 that have entered the underfloor space 6 from the joint portion 34 cannot reach the base 14 or the like. for that reason,
There is an advantage that the termites 3 can be reliably prevented from climbing the inner side surface 32b of the outer peripheral rising portion 32 and entering the shaft set B or the floor set C.

Similarly, when a rising portion 35 or a skewer (not shown) is provided inside the outer periphery rising portion 32, the termite-control sheet 5 is similarly protruded outside the rising portion 35 or the slab. And the upper surface 3 of the base slab 33
3c and the height from the rising portion 35 or the top end 35c of the skelet, and the height of the termite sheet 5 exposed to the underfloor space 6 at the time of fixing to the rising portion 35 or the shackle 8
If the sum of the shortest distance from the lower surface side of the termite control sheet 5 to the upper surface side of the terminating sheet 8 via the tip 5b of the termite sheet 5 is set to 1 m or more, the termites 3 will climb up the rising portions 35 or the slabs. There is an advantage that it can be surely prevented from entering the group B or the floor group C.

The rising portion 35 may be formed continuously, or may be formed in a columnar shape or the like. When the pipe 20 is provided in the underfloor space 6, the termite sheet 5 may be provided on the outer peripheral surface 20 a of the pipe 20 in the same manner as in the first embodiment.
