Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a termite control structure, and more particularly to a termite control structure for preventing damage of buildings and structures due to termites.

[0002]

2. Description of the Related Art Conventionally, as a technique of this kind, a method of treating an underfloor soil with an anti-termite agent, a method of applying an anti-termite agent to a wood portion, and a dovetail board attached to the under-floor (Jpn.
72, 7-35937, etc.), an anti-termite sheet (trade name, manufactured by Aridan, Fukubi Chemical Co., Ltd.) in which a termite-preventing agent is kneaded into a plastic sheet, and an anti-termite mesh having a glass fiber cloth surface coated with a boron compound (trade name , Termite shutters, Dainippon ant wood antiseptic), glass fiber cloths alone which termites cannot pass through, wire netting, metal plates, etc., or a method of laying dry sand all over the floor (JP-A-58-4113).
6, JP-A-8-154564, etc.) and the like have been proposed and put to practical use.

[0003]

However, the former method using an ant-preventive agent is reprocessed periodically (every 3 to 5 years).

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is characterized in that a cloth foundation is provided with a support portion for supporting a holding concrete floor plate and / or a termite-proof layer material. By supporting the presser concrete floor plate and / or the ant-repellent layer material by the support part, the moisture-proof presser concrete floor plate and the ant-repellent layer material are always pressed against the surface of the support part by its own weight. Even if it goes wrong due to the passage of time or an earthquake, the holding concrete floorboard and the ant-repellent layer material are constantly in close contact with the bearing, and there is no gap between them, so termite intrusion is completely prevented. It is. The bearing portion of the present invention may be one in which the hold down concrete floor plate and / or the ant-repellent layer material is simply placed, and the bearing concrete floor plate and / or the ant-repellent layer material is embedded in the hold-down concrete floor plate and / or the ant-repellent layer material. Alternatively, it may support the ant-preventive layer material.

In addition, a concrete adhesive layer (trade name, load bond,
By placing a repellent adhesive layer such as Sekisui Resin), DK seal (trade name, made by Dainippon Timber Preservative) or coal tar pitch, the termite intrusion gap is completely closed, and the termite prevention performance is further improved. improves. Further, as an example of a method of closely attaching the ant-proof layer material to the bearing surface or the placing surface of the holding concrete floor plate, a method of placing a pressing sand on the ant-proof layer material to improve the adhesion by the weight of the sand Or applying an adhesive or repellent adhesive to the underside of the ant-repellent layer material or fixing the ant-repellent layer material with concrete nails, etc., which closes the entry gap and completely prevents the termites from entering. It Regardless of the material, it is desirable that the ant-preventive layer material is a thin plate-like material that is highly flexible and easily adapts to the unevenness and unevenness of the surface of the bearing portion or the holding concrete floor plate.

The bearing in the present invention is provided on the cloth foundation and is substantially at the same level as the surface level of the soil under pressure, but slightly above the surface level of the soil under pressure.
If the concrete floor plate and the ant-preventive layer material are always kept in close contact with the bearing part by its own weight, or if the concrete floor plate thickness is increased to prevent cracks near the rising part of the concrete floor plate, the bearing part height is increased. The height may be lower than the height of the top surface of the ground, and the height of the bearing may be appropriately selected according to the purpose. The support portions are provided on the inner side in the case of the cloth foundation forming the outer periphery of the building, and on the inner and outer surfaces in the case of the partitioning cloth foundation. In addition, in the case of the entrance-to-ground concrete or the terrace that is provided outside the building, it is provided outside the cloth foundation. The position at which the support portion is provided is not particularly limited, but it is preferably provided at the rising portion of the cloth foundation. The support portion is usually provided substantially horizontally and may be provided so as to project in the horizontal direction at the above-mentioned position of the cloth foundation, but it is formed by raising the inverted T-shaped footing as it is to form the support portion. It is preferable in terms of easiness.
Further, the support portion can be provided so as to be inclined, as will be shown in an embodiment later.

It is desirable that the support portion provided on the rising portion is formed by driving at the same time when the rising portion is formed. However, there is no particular problem with the connecting structure or the backing attachment. In addition to concrete, the material of the bearing is a plate-like body made of asphalt concrete, metal, plastic, ceramic, etc., and has flexible "Aridan (product name, Fukubi Chemical)""Alikiller (product name) , Kodama Chemical Co., Ltd.), “Lock Sheet (Yoshitomi Pharmaceutical Co., Ltd.)” and “Termite Shutter (trade name, manufactured by Dainippon Timber Preservative Co., Ltd.)” can also be integrated with concrete, and the gaps that substantially constitute these There is no particular limitation as long as it has a structure in which termites cannot enter. Further, the support portion may be formed by partially cutting out the rising portion.

The basic form of the cloth foundation structure is an inverted T type, but various types such as a high foundation, a shallow foundation, an eccentric foundation, a reinforced foundation, a PC foundation, etc. may be used depending on the structure / weight of the building, ground conditions, adjacent land, etc. Since the foundation is adopted, the foundation structure may change depending on the site even within one building. Therefore, since various conditions are added when a bearing is provided on the rising part, there is no fixed form, and the bearing position height and bearing length may be determined each time, and the floor board height may be higher than the footing top height depending on the situation. It may be selected as appropriate within the following range in which the purpose of installation of the bearing can be utilized.

The support formed by raising the footing is preferably designed flexibly in accordance with the above-mentioned various conditions of the basic design at the time of building a house. There is no particular limitation as long as it is possible to effectively support the holding concrete floor plate and / or the termite-preventing layer material within the range of the edge height and the purpose of preventing termites from entering is achieved. It is desirable to form the support part with the structure intended by the present invention, but for example, a part or all of the footing may be formed in relation to a shallow foundation, a deformed foundation, a formwork, or to thicken a part or all of a concrete floorboard. Even if it is also used as a support part, if the footing has the function of a support part, it is possible to add a structure such as unevenness that can fulfill the purpose of the support part and to deploy an anti-termite material or an anti-termite layer material, etc. It can be regarded as a bearing of the present invention. Also, pay attention to the fact that there are no concrete defects in the bearing, and if the strength of the bearing is required due to structural reasons such as high foundations, rebar reinforcement or ant-proof material or ant-proof layer material should be used effectively. Just deploy.

In addition, in consideration of ensuring the quality of the concrete of the holding concrete floor board placed on the bearing, at the time of placing the concrete placed on the bearing, tapping work and vibration filling are performed to make the concrete dense. The ant repellency is improved by paying attention to ensuring mutual adhesion and mutual adhesion. If the top surface of the footing part that also functions as a bearing part is a smooth surface with plastering iron finish while the concrete is uncured, the fluidity of the concrete of the concrete floor board to be placed increases the adhesion and airtightness, Also when sandwiching an anti-termite layer material or an anti-termite material, the adhesion and the airtightness are increased and an intrusion gap is not formed, which is desirable. Also, when implementing a bearing that raises the footing, the height of the bearing and the footing that is not the bearing may be different, but it is troublesome because the concrete formwork work and concrete placing work are separate. In this case, the heights of the left and right bearings may be unified, which does not depart from the gist of the present invention.

It is also possible to provide a convex portion or a concave portion for blocking an ant (termite) on the surface of the support portion. The protrusions may be provided in the same concrete form in a streak shape at the time of forming the bearing, or may be made of another material such as vinyl chloride resin, polystyrene resin, polyester resin, polyamide resin, or another synthetic resin or metal. It is also possible to embed a part of a band-shaped body, a shaped product, a square pipe, a round pipe, etc. on the bearing part side and integrate the rest by embedding it on the concrete floor board side. As a method of attaching the convex portion to the bearing portion, pre-attached concrete may be placed in the formwork in advance, or the concrete of the bearing portion may be embedded and fixed while it is uncured. After solidification of the above, it may be fixed to the upper surface of the support portion with nails or an adhesive.

The ant-blocking recess is preferably formed at the same time as the formation of the bearing, and the recess formed between the holding concrete floor plate and the ant-preventive layer material may be filled with the ant-proof material. It is also possible to form the holding concrete floor plate and the ant-repellent layer material along the recess, and further fill the recess formed on the concrete or sheet with the ant-prevention material.

The termite proof material is not particularly limited as long as it can prevent termites from entering through the space between the holding concrete floor board or termite proof layer material and the support portion. Part 1
One is, for example, a particle size of 5 mm or less, preferably 3 mm or less, more preferably 2 mm or less, having a weight that termites cannot eliminate, non-edible, and excellent in corrosion resistance. Particles that are not soaked, such as crushed stone particles,
Examples thereof include glass particles, resin particles and metal particles.

Two of them are non-edible materials such as coal tar pitch, asphalt bituminous material and sealing material having rubber elasticity, which have excellent adhesiveness to concrete surface, and have no gaps, and termites cannot penetrate. Some of them cannot be excluded due to termites. The above termite-preventing materials may be used alone or in combination of two kinds, or they may be kneaded and integrated.

Moisture-proof film is J
It is specified as a polyethylene film (0.1 mm or more) equivalent to or higher than IS A6930 and JIS Z1720, but it is desirable to substitute the above-mentioned alidan, ant killer, or lock sheet as a moisture-proof film because moisture-proof and termite-proof properties are added. .

It is also possible to dispose an anti-termite layer material in place of the presser concrete floor plate in the support portion, or to use both in combination.
That is, it is possible to dispose the ant-repellent layer material on the upper surface or the lower surface of the holding concrete floor plate.

The termite-proof layer material is a non-edible sheet-like material that does not allow termites to pass through, and examples thereof include alidan, ant killer, lock sheet, termite shutter, glass cloth, and wire mesh. Other than sheet materials, it is formed with asphalt concrete, bitumen bitumen, coal tar, etc. covering the bearing and soil ground surface. Of these, inexpensive asphalt-based or coal tar pitch is preferable in that it adheres well to the bearing portion and adheres, and exhibits an excellent anti-termite effect.

Further, in the case where it is not desired to inhibit the ventilation of the underfloor soil, a breathable ant-repellent layer material such as a glass cloth or a wire mesh with fine textures that termite shutters and termites cannot pass is laid all over the floor, It can also be placed on the bearing.

It is also possible to mechanically attach the holding concrete floor plate and / or the termite-proof layer material arranged on the support portion, and further these and the moisture-proof film to the support portion. As a mechanical attachment means, an anchor bolt or a reinforcing bar embedded in the bearing can be used, or a bolt or a nut can be attached. With the holding concrete floor board in the present invention,
Non-reinforcing bar, with welding wire mesh bar (Example: 6φ x
(100 × 100mm mesh reinforcement) etc. is a general term for floorboards with reinforcing bars. Further, it is also possible to integrate the support portion provided on the cloth foundation of the present invention and the pressing concrete floor board, and in this case, the pressing concrete floor board is formed at the same time as the construction of the cloth foundation, and the joint portion between the two is formed. Not a more complete termite structure is built.

The termites not only enter from the joint between the cloth foundation and the concrete floorboard, the connection between the cloth foundation and the anti-termite layer material, but also from the cracks generated in the concrete floorboard and around the pipe. Therefore, it is preferable to use high-quality concrete that is unlikely to cause cracks in the holding concrete floor plate, and it is desirable to use an asphalt floor plate in place of the concrete floor plate because the adhesion with the support part is improved and the occurrence of cracks is suppressed. .

Termites also enter through cracks in the presser concrete floorboard, but when they enter through cracks near the structure such as cloth foundations and pipes, dovetails are formed on the wall surface of the structure to facilitate the wood part. On the other hand, it is said that the probability of reaching the xylem is extremely low because the structure cannot be defined blindly even if it enters through a crack away from the structure. Therefore, it is a very effective anti-termite method to prevent cracks from being generated in the vicinity of the structure of the concrete floorboard, and at least 100 mm or more, preferably 300 mm or more from the contact surface between the structure and the concrete floorboard.
The object is achieved by using a crack-resistant floor plate structure having a thickness of about 100 mm, more preferably about 500 mm. With such a structure, cracks are generated in the central portion of the floor plate other than the crack resistant structure, and even if termites invade from the cracks, they cannot reach the wood portion. In addition, when an anti-termite layer material is used together in the central portion, substantially no invasion occurs. As described above, it is economical and desirable to make the main part crack resistant, but it is not out of the purpose to make the entire floorboard structure crack resistant.

One of the crack resistant structures is to increase the thickness of the above portion. For example, it is more preferable to uniformly thicken the crack resistant structure portion, or to particularly thicken the portion near the cloth foundation and successively thin it toward the central portion. In this case, of course, the height of the bearing will be low, and at the joint surface between the bearing and the floor board, ant-proof material or ant-repellent layer material will be placed, and mortac (product name; concrete adhesive) or load bond (product name, Sekisui) It is even more preferable to bond them with an adhesive such as resin. Further, as another crack resistant structure, it is also effective to reinforce and form the crack resistant portion with a reinforcing material such as a welding wire mesh, expanded metal, rebar, and cracks (trade name; resin mesh).

As described above, it is desirable that the footing, the cloth foundation rising portion and the support portion of the present invention are integrally formed at the same time. However, when a joint portion is formed due to the foundation shape, the form, the ground, etc. However, there is a high possibility that termites will invade from the splicing section, and therefore it is desirable to appropriately install and deploy a termite proof material, a concrete adhesive, or the like at the splicing section. In the case where the footing and the cloth foundation rising joint are formed, if the footing on the outdoor side is approximately at the height of the outdoor GL, invasion into the interior from the joint can be prevented.

Further, in the case of a piecing type cloth foundation, a holding concrete floor plate and / or an anti-termite layer material is provided between the footing and the rising part to more effectively exert the anti-termite effect. Can be made. In this case, it is preferable that the rising portion, the presser concrete floor plate and / or the ant-preventing layer material, and the footing are integrated by a reinforcing bar or the like.
Further, it is preferable to interpose an anti-termite material or fill a concrete adhesive in the gap between the joints.

After that, the support portion 3 which is post-cast with concrete or asphalt concrete is provided so as to be inscribed and closely contacted with the rising portion 1a of the cloth foundation 1. 6 is an ant-blocking convex portion 8 is an ant-repellent layer material, and 4 is a holding concrete floor plate. In addition, by providing the concrete adhesive 15 or the repellent (termite-proof) adhesive layer 30 in the gap between the cloth foundation rising portion 1a and the support portion 3, the termite penetration gap is closed. As another example of the bearing portion 3 in this embodiment, instead of concrete adhesive or the like, an anti-termite material (eg, glass particle body) may be filled and formed in the bearing portion forming portion. Alternatively, it may be formed by impregnating it with an anti-termite emulsifier (trade name: Afrecon anti-termite emulsifier, Nippon Pavement, Alidan anti-termite emulsifier).

Example 28 In FIG. 29, the pressing concrete floor board 4 is arranged on the support portion 3 of the cloth foundation 1, and the joining surface between the rising portion 1a of the cloth foundation 1 and the pressing concrete floor board 4 is made uneven. Here is an example. By forming the projections and depressions in this way, the connection receiving area increases and the close contact state is maintained, so that the termites can be effectively prevented from entering. In the present embodiment, if the depth of the unevenness is equal to or larger than the maximum shrinkage dimension of the floor plate 4, the ant-preventing property can be secured even if the support portion 3 is omitted.
