Description

  TECHNICAL FIELD The present invention relates to a building ant structure and a foundation ant-proofing method for preventing termites from invading termites from the outside of a peripheral rising portion of a foundation such as a cloth foundation or a solid foundation. The present invention relates to a ant-proof structure for a building that prevents termites from entering between the ant-proof plate members provided on the outer surface of a rising portion, and a basic ant-proof method for a building.

  Conventional termite control techniques in buildings include, for example, a method for treating a termite-treating chemical on wood or soil under a building in a range of about 1 meter from the ground under the building, and a small amount of chemical in the termite. Methods such as the bait method that eradicate poisonous bait are known. However, the above-described method for treating chemicals under the floor of a building has a problem in that the environment in the building is contaminated with chemical substances. In addition, the bait method has a problem that the vitality of the entire colony is reduced, and it takes at least a few months to two years from the start to the end.

  Therefore, in order to solve the above-mentioned problems, various methods for physically preventing the entry of termites without using a drug have been proposed. In the construction method that physically prevents the entry of termites, the foundation made of concrete itself is not eroded by the termites, so the decorative material and heat insulating material attached to the rising surface of the foundation and the outer peripheral rising part of the foundation The path of the termites that pass between them consists of, for example, a mesh sheet that is resistant to termite secretions and knitted with a corrosion-resistant material of at least Shore D70 or higher. In this direction, a termite sheet having a diameter smaller than the maximum dimension of the termite head cross section to prevent intrusion is attached to prevent the termites from entering the building (for example, Patent Document 1).

By the way, various plate members such as exterior materials and heat insulating materials are often fixed on the outdoor side of the outer peripheral rising portions of foundations such as fabric foundations and solid foundations of buildings. In order to prevent termites from entering the inside of the plate member, various types of plate members having ant-proofing properties have been proposed. Specifically, for example, from an ant-prevention heat insulating material (see Patent Document 2) formed by foaming and curing by adding an ant-proofing agent to the raw material of the heat-insulating material, or a polycarbonate-based resin foam having a hardness and density not corroded by termites. The ant-proof material which becomes (refer patent document 3) is proposed.

  The ant-proof plate member 4 is not limited to this, and fiber-based heat insulating materials such as glass wool and rock wool containing chlorpyrifos-based, organic phosphorus-based and pyrethroid-based ant-proofing agents, polystyrene foam, polyethylene Various plate-like members that can prevent termite erosion such as foam, polypropylene foam, polyurethane foam, phenol resin foam, vinyl chloride resin foam, and highly filled inorganic resin foam, and have heat insulation performance, are used as the anti-rust plate member 4. Can be used. In addition, the ant-proof plate member 4 is not limited to a heat insulating material, for example, hard equipment (for example, tile, ceramic plate, cement plate, calcium carbonate plate, calcium silicate plate, wood piece cement plate, magnesium carbonate plate, etc.) Or ceramics in which glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc., are mixed by extrusion molding, press molding, injection molding, paper making, etc. Siding material or various fibers woven in cloth or three-dimensional shape, impregnated with cement, clay, etc. to form a panel, dried, steam-cured, fired, etc.), and also made of metal Panels, metal siding materials (building materials in which a core material such as synthetic resin foam is laminated on the back surface of a metal surface material, and a synthetic resin material between the metal surface material and the back surface material. Building materials is sandwiched a core member of the body such as, etc.), synthetic resin plate, it is possible to use various anti-termite resistant plate member 4 of precast concrete material or the like.

  As described above, the ant-prevention plate member 4 is made of an ant-proof heat insulating material having an ant-proofing property and a heat-insulating property. Although the ant-proof structure 1 of the building of the embodiment can be used, the ant-proof board member 4 of the present embodiment is not limited to the one having heat insulation, and is formed of a material that does not erode by termites. Various ant-proof plate members 4 attached to the outer surface of the outer peripheral rising portion 3 of the foundation such as a decorative material can be used.

  Moreover, the ant-proof board member 4 is not limited to what is formed with a single material, For example, as shown in FIG. 4, the siding material 12 is attached to the outdoor side as an ant-proof layer, and indoor side May have a two-layer structure provided with a heat insulating material 13 having no ant-proofing property. Even if comprised in this way, the gap | interval of the termite-proof board member 4 and the extension part 5 is coat | covered with the lower end side ant-proof sheet | seat 6 from the outdoor side, and the gap | interval between ant-proof board members 4 is also intermediate from the outdoor side. Since it is covered with the partial ant protection sheet 7, termites do not reach the heat insulating material inside the siding material 12, and the ant protection can be maintained. In addition, by making the inside of the non-ant-proof layer in this way, various materials having no ant-proof property can be used, and an appropriate material can be selected from the viewpoints of heat insulation and material cost. .

  Furthermore, the ant-proof plate member 4 can be composed of three or more layers if a member having ant-proof performance is provided on the surface, for example, various ant-proof plates having ant-proof and heat-insulating properties. The member 4 may be combined with a moisture-proof material such as a moisture-proof sheet, a sound-insulating material, a sound-absorbing material, a vibration-proof material, tiles, mortar, and the like. Also, polycarbonate foam plates and fiber insulation such as glass wool and rock wool, foam resin systems such as polystyrene foam, polyethylene foam, polypropylene foam, polyurethane foam, phenol resin foam, vinyl chloride resin foam, inorganic highly filled resin foam, etc. The heat insulating material can also be used as a composite ant proof heat insulating material bonded with an adhesive or the like. If it does in this way, after reducing the usage-amount of an expensive polycarbonate foaming material, the thickness of an ant-proof material can be ensured and the conventional heat insulation performance can be exhibited.

  When attaching the termite-proof plate member 4 to the outer peripheral rising portion 3 as described above, the outer surface of the outer peripheral rising portion 3 and the termite-preventing plate member 4 are fixed via an adhesive that is not eroded by termites such as adhesive mortar. Can be made. Moreover, the bonding method of the ant-proof plate member 4 is not limited to this. For example, before forming the outer peripheral rising portion 3 by placing concrete, the mold used for forming the outer peripheral rising portion 3 is used. Of these, the ant-preventing plate member 4 can be fixed to the outer peripheral rising portion 3 by fixing the ant-repellent plate member 4 to the inner side surface of the formwork arranged on the outdoor side and then placing and curing the concrete.

  Here, termites are incompletely metamorphic insects that live closely related to cockroaches, and are a generic term for termites (Isoptera) Isoptera. This termite has a non-deformable rigid head. Examples of such termites include various termites such as Yamato termites and house termites.

  Further, as the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7, for example, a synthetic resin sheet kneaded with an ant protection agent such as “ant cut (trade name, manufactured by Fukubi Chemical Co., Ltd.)”, “termite” Conventionally known various sheet materials and plate materials having ant-proofing properties such as glass fiber sheets coated with an ant-proofing agent such as a shutter (trade name, manufactured by Dainippon Wood Preservation Industry Co., Ltd.), etc. Resistant corrosion resistance that is resistant to secretions such as formic acid, has at least about Shore D70 hardness, which is a hardness that termites cannot chew, and has a service life of several decades in the environment of use What consists of a property material is preferable.

  As the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7 as described above, for example, a sheet material or a plate material made of a corrosion-resistant material such as a metal or a synthetic resin can be cited. As shown, a stainless steel mesh woven from stainless steel wire 14 and having a number of meshes (holes) 15 that are smaller than the maximum linear dimension of the termite head cross section in either direction (eg, “TERMI mesh (TERMI) -MESH, trade name) "manufactured by Termimesh Japan Co., Ltd.] and the like, and a mesh sheet that is excellent in flexibility and that can be easily shaped by cutting, bending, contouring at the time of bending, and the like is preferable.

  In addition to the stainless steel mesh, the mesh sheet as the termite barrier material is, for example, a wire lath woven or knitted from fibers, filaments, strands, etc. of ceramics, glass, synthetic resin, metal (especially stainless steel), etc. Various materials such as non-woven fabric, punching metal, and metal lath can be used. In short, what is necessary is just to have many holes, such as mesh | network 15. The shape of the hole is not particularly limited, and may be an appropriate shape such as a rectangular shape or a circular shape.

  As shown in FIGS. 1 to 3, the lower-end-side anti-rust sheet 6 configured as described above is provided with the outdoor side surface and the anti-proof surface of the extending portion 5 extending from the lower end of the outer peripheral surface 34 of the solid base 2 to the outdoor side. The ant plate member 4 is covered over the vicinity of the lower end of the outdoor side surface. Further, as shown in FIG. 3, the intermediate part ant protection sheet 7 covers a plurality of ant protection board members 4 arranged side by side and the side ends that abut each other, and the outdoor side surfaces of the upper and lower ends that abut each other. Is done. When attaching the lower-end-side anti-rust sheet 6 and the intermediate-portion-preventing sheet 7, the anti-rust sheet is cut into a predetermined length, and the covering member is a fixing member such as a nail, a nail with a washer, a staple, etc. Temporarily stop at. Then, from the outdoor side of the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7, adhesion to the outer peripheral rising part 3 and the ant protection board member 4 is performed by applying an adhesive mortar or the like in which an appropriate polymer is mixed with the mortar. do it.

  As described above, the gap between the extension portion 5 and the termite-preventing plate member 4 is covered with the lower end-side termite-protecting sheet 6, and the gap between the termite-preventing plate members 4 is covered with the intermediate-portion-preventing sheet 7. Therefore, termites cannot enter the gap between the outer peripheral rising part 3 and the termite prevention plate member 4, and termites can be prevented from entering the building. Therefore, it is possible to reliably protect the frame assembly and the floor assembly from the damage caused by termites without polluting the environment in the building.

  Here, when the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7 made of a corrosion resistant material are used, there is no risk of the termites eroding them, so that the termites can more reliably enter the space under the floor. There is an advantage of being able to stop. Moreover, even when a mesh sheet is used as the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7, the linear dimension of the holes such as the mesh 15 is larger than the maximum linear dimension of the termite head cross section in any direction. By forming it small, termites can be prevented from passing through the mesh sheet. In addition, since the mesh sheet has a large number of holes 14, there is an advantage that the mesh sheet can be more firmly attached by an anchor effect in the case of bonding with an adhesive mortar.

  In addition, the size of the mesh 15 of the mesh sheet used as the lower end side ant protection sheet 6 and the intermediate part ant protection sheet 7 is about 1.1 to 1.25 mm for the termite ants, and the ants for the Yamato termites. Therefore, it is desirable to set the linear dimension of the hole to about 1.0 mm or less in any direction in an area where Yamato termites live. In addition, examples of the fine aggregate contained in the adhesive mortar include sand that cannot be crushed by termites, but the applied adhesive mortar passes through the holes 15 so that the applied adhesive mortar is not eroded by termites in any part. While using a thing of a magnitude | size, it is desirable to mix | blend so that a space | interval may become smaller than 1.0 mm.

  In addition, a pipe 16 for supplying and discharging water into the building passes through the ant-risk plate member 4 fixed to the outer peripheral rising portion 3 and the outer peripheral surface 34 of the solid foundation 2 including the outdoor side surface of the outer peripheral rising portion 3. Water is supplied into the building and drained from the building through the pipe 16. If there is a gap between the through-hole of the outer peripheral rising part 3 and the through-hole of the termite-preventing plate member 4 and the outer peripheral surface of the pipe 16, there is a risk that termites will enter the building through the gap. Therefore, in order to prevent termites from entering the inside of the building from the gap between the pipe 16 and the outer peripheral rising portion 3, a pipe-use anti-rust sheet 17 is used.

  As shown in FIG. 6, this pipe ant-proof sheet 17 has a hat shape and is kneaded with the same stainless steel mesh sheet and ant-proofing agent as the above-mentioned lower-end ant-proof sheet 6 and intermediate part ant-proof sheet 7. Various sheet materials having ant-proofing properties such as a synthetic resin sheet, a glass fiber sheet coated with an ant-proofing agent, and a metal or synthetic resin-made sheet material made of a corrosion-resistant material are extrapolated to the outer periphery of the pipe 16. A cylindrical portion 18 is formed by processing into a cylindrical shape having a size, and a flange portion 19 is formed on one end side and is formed of the same ant-proof material as described above.

  When attaching the ant proof sheet 17 for piping, as shown in FIG. 7, the tube part 16 of the ant proof sheet 17 for piping is extrapolated to the pipe 16 projecting to the outdoor side of the ant protection plate member 4, The eaves part 19 is brought into contact with the outdoor side surface of the termite-proof plate member 4. Then, the pipe ant-proof sheet 17 is bonded to the outer peripheral surface of the pipe 16 and the outdoor side surface of the ant-proof plate member 4 with an adhesive such as adhesive mortar. If it does in this way, a termite cannot enter the clearance gap between the through-hole of the dent prevention board member 4 and the outer periphery rising part 3, and the outer peripheral surface of the piping 16, and can prevent the penetration | invasion to the inside of a building.

  Next, a first basic ant protection method for constructing the building ant protection structure 1 according to the first embodiment configured as described above will be described with reference to FIGS. 8 to 11.

  As shown in FIG. 8, the first basic ant protection method is to first dig down from the ground surface to a predetermined depth, improve the ground, etc., then spread the cracked stone 11 and then throw away the concrete 10 from there.
