Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for constructing an ant proof structure under a floor of a building.
[0002]
[Prior art]
Conventionally, in the underfloor structure of a building, the floor bundle is usually wooden, and it has been necessary to prevent the floor bundle from being corroded by moisture in the ground. Therefore, it is common to install the boulder portion so as to protrude from the upper surface of the ground. In wooden buildings, white ants often crawl up from under the floor via boulders and floor bundles from the ground, often causing damage to the building. In order to reduce these damages, there is a method of laying an ant-proof sheet on the ground. In this case, the ant-proof sheet reduces the ant climbing from the ground to the building. The following conventional techniques exist as a method of laying ant-proof sheets on the ground.
[0003]
(1) Make a hole in the part corresponding to the bunch stone of the ant-proof sheet, and when the ant-proof sheet is laid on the ground, the bunch stone will be exposed from the ant-proof sheet. And the clearance gap between a bunch stone and an ant-proof sheet | seat is adhere | attached with the adhesive agent etc. which contain the chemical | medical solution for ant-proof. (Japanese Patent Publication No. 4-15859)
(2) Make a hole in the flexible ant protection sheet that is slightly smaller than the protruding part of the boulder. Then, the boulder and the ant-proof sheet are pressed down through the bunch through the hole and brought into close contact with the ground. (Japanese Patent Publication No. 6-76704)
[0004]
[Problems to be solved by the invention]
However, in both technologies, it is necessary to expose the bunch stones from the ant proof sheet when laying work. For this reason, in both the techniques (1) and (2), it is necessary to make a hole in the ant-proof sheet beforehand in order to expose the boulders from the ant-proof sheet. Furthermore, in the above technique (1), it is necessary to bond the gap between the boulders and the ant-proof sheet with an ant-proofing adhesive or the like, which takes time. Also in the technique (2), it is necessary to push down the ant-proof sheet in close contact with the boulders, and it takes a lot of work because a force is required to perform the work. Therefore, it has been a problem to reduce the labor of laying work.
[0005]
In addition, if the ant-proof sheet is laid on the ground and a bunch stone as it is without making a hole in the ant-proof sheet, the above work is saved, but the bunch stone protrudes from the ground, so the sheet is laid as it is Then, it is easy to produce a clearance gap between a sheet laying surface and a boulder, especially a boulder side. Therefore, when a person steps on the portion, the sheet moves, and the joint portion of the sheet is peeled off, and there is a possibility that an uncoated portion is formed. Furthermore, problems such as white ants climbing from there may occur, which may reduce the ant protection effect.
[0006]
In order to solve the above problems, the present invention provides a method for constructing an underfloor ant structure that reduces the labor of laying an ant proof sheet without impairing the function of the prior art.
[0007]
[Means for Solving the Problems]
The invention according to claim 1, a method for applying a structure for termite floor lower portion, the ground of the underfloor section, the upper surface of the upper surface and the ground of the bundle stone substantially the same height, and bundle sandwiching a step of providing the bundle stone upper surface of the stone so as to expose the upper surface of the ground, and laying rather step the anti-termite sheet over its across and these ground and bundle stone, the termite sheet And a step of installing a floor bundle on the boulder.
[0008]
According to the present invention, since the upper surface of the boulder and the upper surface of the ground are substantially the same height, it is not necessary to perform a special process, work, etc. just by placing an ant-proof sheet on the ground and the boulder. However, the sheet can be laid without causing a large gap between the stones. Therefore, it is possible to prevent a situation in which the sheet moves and the seam of the sheet is peeled off when a person steps on the gap.
[0009]
Furthermore, as in the prior art, after processing the ant-proof sheet (for example, drilling), the gap between the boulder and the ant-proof sheet is adhered with an adhesive or the like, or processed to the ant-proof sheet (for example, drilling) ), The work of pressing down the ant-proof sheet in close contact with the boulders is unnecessary.
[0010]
Moreover, since moisture generated from the ground is blocked by the ant-proof sheet, even if the top surface of the ground and the top surface of the boulders are at the same height, it effectively prevents the floor bundle from corroding due to moisture on the ground. I can do it.
[0011]
In particular, when the floor bundle is made of a synthetic resin material, it is possible to substantially avoid corrosion of the floor bundle due to moisture.
[0012]
Moreover, about said ant-proof sheet | seat, it becomes possible to prevent more reliably that a floor bundle corrodes by moisture by using the material with low moisture permeability represented by the synthetic resin sheet | seats.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIG. However, the present invention is not limited to the following embodiments.
[0014]
A foundation 50 is erected on the ground 10, and a bunch stone 20 is provided in a lower floor portion surrounded by the foundation 50. The ant-proof sheet 30 is laid on the entire surface surrounded by the foundation 50.
[0015]
The floor bundle 40 is installed on the bundling stone 20 with the ant protection sheet 30 interposed therebetween, and a building is installed on the upper surface of the foundation 50 and the floor bundle 40, although not shown.
[0016]
The height of the upper surface of the ground 10 and the upper surface of the stone 20 are substantially the same. Note that the substantially same height in the present embodiment refers to a height that does not cause a gap between the ant-proof sheet 30 and the bundling stone 20 when the ant-proof sheet 30 is laid.
[0017]
In the illustrated example, a plurality of ant protection sheets 30 are laid, and the ant protection sheets 30 adjacent to each other are connected by a joint portion 31.
[0018]
About the ant-proof sheet | seat 30, the part in the case of the foundation 50 digs up the part at the side of the foundation regarding the lower floor part of the ground 10, and lays the ant-proof sheet | seat 30 on it. In this case, the end of the ant-proof sheet 30 and the foundation 50 do not necessarily need to be in close contact with each other. However, the close contact is preferable because the ant-proof effect is enhanced. A filler 12 represented by sand or the like is filled thereon. Furthermore, the fixing material 14 mixed with the termite-proofing agent is installed on the filler 12 and fixed to the foundation 50. Therefore, the ant-proof sheet 30 is fixed at the base.
[0019]
The ground 10 may be any soil that can be constructed. Further, the height of the ground upper surface of the portion surrounded by the foundation 50 (under the floor portion) and the other portions may be different as shown in FIG. 1 or may be the same height. And the height of the upper surface of the stone 20 need only be substantially the same.
[0020]
However, as shown in FIG. 1, the ground 10 in the lower floor portion surrounded by the foundation 50 is raised with soil or the like, and the height of the upper surface of the ground 10 in the lower floor portion is higher than the height of the upper surface of the ground in the portion other than the lower floor portion. You can also If it does in this way, since the moisture which generate | occur | produces from the ground 10 can be suppressed, it becomes possible to prevent the corrosion of the floor bundle 40 which arises by moisture. Furthermore, water droplets or the like accumulated in the lower floor portion can be drained to the ground 10 other than the lower floor portion, and drainage can be improved.
[0021]
In addition, although the foundation 50 in this embodiment is usually a cloth foundation, there is no particular problem as long as the above embodiment can be performed, such as an independent foundation.
[0022]
The ant-proof sheet 30 is kneaded and impregnated with an ant-proofing agent. The sheet material is not particularly limited, but an ethylene-vinyl acetate alcohol copolymer (EVA), an olefin resin typified by low density polyethylene, a synthetic resin sheet typified by polyvinyl chloride, or the like, or Nonwoven fabrics or metal meshes made by bonding chemical fibers with adhesives can be used, but the use of flexible materials will ensure close contact with the ground 10 and the boulders 20 even if there are some irregularities. Is preferable because it is possible. Particularly preferred is a synthetic resin sheet excellent in moisture resistance. Anti-anticides include fenitrothion, phoxime (known organophosphorus insecticides), pyrethroids (silafluophene, etofineprox, etc.), pyrethoids (bifenthrin, cypermestone, deltamethrin, permethrin, permethrin, allethrin, tralomethrin, etc.) Carbament drugs (proboxul, phenocarb, sebin, etc.), chlornicotil drugs (imidacloprid, acetapride, etc.) and the like are mainly used, but are not particularly limited as long as they have ant-proofing properties.
[0023]
The material used for the floor bundle 40 is not particularly limited, but in addition to wood conventionally used mainly, olefin resins represented by polyethylene and polypropylene, polyamide resins such as polystyrene, polyvinyl chloride, and nylon , Synthetic resins such as FRP, and metal materials such as stainless steel can also be used.
[0024]
In this way, since the top surface of the bunch stone 20 and the top surface of the ground 10 are substantially the same height, a special process, work, etc. can be performed only by laying the ant-proof sheet 30 on the ground 10 and the bund stone 20. Even if it does not give, it can install without producing a gap between the ant-proof sheet 30 and the bundling stone 20.
[0025]
Therefore, when the operator or the like steps on the gap, the ant protection sheet 30 is less likely to move, and the joint portion 31 is less likely to be peeled off. Therefore, it is possible to prevent the ground 10 from being exposed due to a gap between the ant-proof sheets 30.
[0026]
Furthermore, the lower floor portion surrounded by the foundation 50 completely covers the ground 10 with the ant-proof sheet 30, the filler 12, and the fixing material 14, so that there is no portion where the ground 10 is exposed. Therefore, after drilling the ant-proof sheet 30, the gap between the stone 20 and the ant-proof sheet 30 is bonded with an adhesive or the like, or after the ant-proof sheet 30 is drilled, Even if it is not brought into close contact with the bunch stone 20 and pushed down, a sufficient ant protection effect can be obtained.
[0027]
Therefore, the labor for laying the ant-proof sheet 30 can be reduced.
[0028]
Moreover, since the moisture generated from the ground 10 can be partially blocked by laying the ant-proof sheet 20 on the ground 10, the upper surface of the ground 10 and the upper surface of the bundling stone 20 are made substantially the same height. However, it is possible to effectively protect the floor bundle 40 from being corroded by moisture in the ground 10.
[0029]
In addition, the floor bundle 40 is made of a material that does not corrode with moisture such as olefin resin typified by polyethylene and polypropylene, synthetic resin such as polystyrene, polyvinyl chloride, and polyamide resin, and metal material such as stainless steel. By making it, corrosion resistance can be imparted to the floor bundle 40 itself, and corrosion due to moisture can be avoided more.
[0030]
Moreover, it becomes possible to further block moisture generated from the ground 10 by using a material having excellent moisture resistance such as a synthetic resin among the sheet materials listed above for the ant-proof sheet 30. . Therefore, it is possible to more effectively prevent the floor bundle 40 from being corroded by moisture.
