Description

The present invention relates to the time of the foundation of the building to the anti-termite how for anti-termite treatment.

  In general, as a method for applying an ant-repellent treatment to the lower floor portion of a house or the like, spraying of an ant-repellent agent or laying of an ant-proof sheet is often performed. However, when soil concrete is placed adjacent to the fabric foundation or independent foundation, it is caused by shrinkage of the concrete at the joint between the foundation and the soil concrete during or after the concrete is cured. Cracks (brick cracks) may occur, and it is very difficult to prevent the invasion of white ants from such cracks only by spraying the above-mentioned termite-proofing agent or laying the termite-proof sheet. In particular, white ants often reach the ground from the inner surface of the foundation from the soil, and the ant protection treatment at the base is very important.

Therefore, as a method of intensively preventing ant at the time of such foundation, for example, in Patent Document 1 below, a groove is formed on the upper surface of the end of the soil concrete along the joint portion between the fabric foundation and the soil concrete. A method of forming and injecting a termite-proofing agent into the groove to be transmitted through the groove is disclosed.
Japanese Examined Patent Publication No. 7-86251 (Page 2, Fig. 1)

  However, since the method described in Patent Document 1 is to form a groove on the upper surface of the soil concrete, there is a possibility that a crack may occur at the bottom of the groove. Regarding this crack, in Patent Document 1, it is described that the termite-proofing agent injected into the groove penetrates into the crack and exhibits a termite-preventing effect, but the width of the crack generated in the soil concrete Since there is considerable variation, it is practically difficult to reliably put an anti-anticide into the crack when the width of the crack is very narrow.

  As a method of solving this problem, a mold is arranged along the inner surface of the foundation, and the soil concrete is formed by injecting and hardening fluid concrete inside the mold. It is assumed that by removing the frame, a gap is formed between the inner side surface of the foundation and the soil concrete, and an anti-anticide is placed in the gap. By adopting this method, it is possible to intentionally form a gap having a suitable dimension between the inner side surface of the foundation and the soil concrete, and to apply the anti-anticide to the inside of the foundation. It can be reliably interposed between the side surface and the soil concrete.

  However, when the above-described method is adopted, in order to ensure that the termite-proofing agent is interposed between the inner side surface of the foundation and the soil concrete, first, the soil concrete is formed along the inner side surface of the foundation. It is necessary to dispose the mold, and then remove the mold, and then put the anti-anticide into the gap formed by removing the mold. Therefore, there has been a demand for reducing labor during construction.

  Then, an object of this invention is to provide the ant-proof method for reducing the effort at the time of constructing the ant-proof structure at the time of a foundation.

The invention according to claim 1 is a method for preventing ant at the base for disposing an anti-fungal agent having fluidity between a foundation of a building and dirt concrete disposed inside thereof. A step of disposing a liquid-dissolving bag enclosing an antifungal agent along the inner side surface of the foundation, and a step of injecting fluid concrete into the soil region on the opposite side of the foundation across the bag. Curing the fluidized concrete to form the soil concrete, and contacting the moisture contained in the fluidized concrete with the bag to melt the bag, A step of disposing the termicidal agent between the inner side surface of the foundation and the soil concrete in a state of being in direct contact with the inner side surface of the foundation and the soil concrete.

According to a second aspect of the invention, the termite control method in foundation of claim 1 Symbol placement, Boarizai being sealed in the bag is characterized in that the particulate.

The invention according to claim 3 is the method of preventing ant at the time of foundation according to claim 1 or 2 , wherein the bag body is arranged along the inner surface of the foundation before the bag body is arranged on the inner surface of the foundation. The step of forming a groove having a bottom surface inclined so that the inner side surface is lowered is disposed in the ground, the bag body is disposed along the groove, and the bag body is melted, whereby the ant-preventing agent is disposed inside the groove. An agent is arranged .

  When the method of the invention according to claim 1 is adopted, after placing a bag body enclosing the fluidity-preventing agent along the inner side surface of the foundation, concrete in a fluid state is injected inside the bag body. Therefore, the bag body can serve as the formwork. Furthermore, the bag body is liquid-soluble, and the anticide is in direct contact with the inner surface of the foundation and the soil concrete only by bringing the bag into contact with the liquid and dissolving the bag body. Thus, it becomes possible to dispose the termite-proofing agent between the inner side surface of the foundation and the soil concrete. Therefore, unlike the conventional method, the process of removing the mold and the process of putting the anti-anticide into the gap formed by removing the mold are unnecessary, thus reducing the labor during construction. However, it becomes possible to reliably interpose the termite-proofing agent between the inner side surface of the foundation and the soil concrete.

Moreover, when the method of the invention of claim 1 is adopted, the dissolution of the bag body is performed by the water contained in the fluidized concrete, so there is no need to bother to perform a step for dissolving the bag body. It is possible to further reduce the labor during construction.

The termite-proofing agent is not particularly limited as long as it has fluidity. For example, the termite-proofing agent is liquid when present inside the bag body, and the bag body dissolves to dissolve the antibacterial agent. The ant agent may be hardened after contacting the inner surface of the foundation and the soil concrete, but if it is granular as in the invention of claim 2 , the soil concrete shrinks with time. Even if the gap between the soil concrete and the inner side surface of the foundation widens, the anti-anticide will follow this shape change, so it is possible to continue the good anti-ant-proofing state even after construction. It becomes.

If the method of the invention according to claim 3 is adopted, a groove having a bottom surface inclined so that the inner surface side is lowered along the inner surface of the foundation before the bag body is arranged on the inner surface of the foundation. When the bag body is disposed on the inner side surface of the foundation and the bag body is melted to form the ground on the ground, the anti-anticide is surely contacted with the inner side surface of the foundation through the bottom surface. It becomes possible to do. Therefore, it is possible to obtain a more reliable ant protection effect .

  An embodiment of the present invention will be described with reference to FIGS.

First embodiment (see FIGS. 1 to 3)
First, the ant-proof structure constructed by the base ant-proofing method according to the present embodiment will be described with reference to FIG.

  A foundation 11 is erected on the ground 10. The foundation 11 is a cloth foundation extending in the depth direction of the figure in the figure, and the side surface on the dirt side is the inner side surface 12.

  A groove 13 extending along the inner side surface 12 is excavated in the ground 10 at the inner side surface 12 of the foundation 11. The bottom surface of the groove 13 is inclined so as to become lower toward the inner surface 12 of the foundation 11. And the soil concrete 14 is cast by the fixed thickness on the ground 10 in the area | region (soil area | region) inside the said foundation 11 including the bottom face of this groove | channel 13. As shown in FIG.

  As the concrete constituting the foundation 10 and the interstitial concrete 14, a mixture of cement, an aggregate such as sand and gravel, and water in an appropriate ratio is usually used.

  A gap 20 having a constant width (in the illustrated example, a width larger than the upper end width of the groove 13) is intentionally secured between the soil concrete 14 and the inner side surface 12 of the foundation 11. An antifungal agent 30 is placed in a region continuous with the groove 13.

  Here, as the termite-proofing agent 30, one having fluidity is suitable, and it may be a liquid termite-proofing agent that has been conventionally used and is semi-cured after filling. It is still preferable if it is semi-permanent and retains fluidity semipermanently. If such a granular ant repellent is used, even if the soil concrete 14 contracts after the completion of the construction and the gap 20 widens, the ant repellent 30 follows this, so that an ideal ant repellent state is provided. Will be maintained.

  Examples of such granular ant repellent 30 include, for example, a coating obtained by mixing a ant repellent agent in a solvent on a surface of particles having a diameter of 0.3 mm to 10 mm, preferably 0.5 mm to 5 mm, What knead | mixed the said ant preventive agent into the said particle | grain is used.

  As the material of the particles, inorganic particles (sand, pumice, zeolite, glass, slag ceramic ground, silica gel, shirasu, vermiculite, quartz sand, clay talc, calcium carbonate, bentonite, diatomaceous earth, magnesium sulfate), activated carbon, synthetic resin (Polyethylene, polypropylene, EVA (ethylene-vinyl acetate alcohol copolymer), PVC (polyvinyl chloride), epoxy resin, melamine resin, nylon, etc.) and the like. Moreover, you may use what has ant-proof performance to particle | grains itself like a boron-type compound, a colemanite, a pointed glass piece.

  Examples of the solvent include water, organic solvents (ethanol, methanol, isopropyl alcohol, xylene, toluene, ethyl acetate, normal hexane, benzene, methyl ethyl ketone) and the like.

  Examples of the anti-antibiotics include pyrethroid-like drugs (silafluophene, etofenprox, etc.), pyrethroid drugs (bifenthrin, cypermestone, deltamethrin, permethrin, permethrin, allethrin, tralomesulin, etc.), carbament drugs (proboxol, fenocarb, sebin, etc.) ), Chlornicotyl drugs (imidacloprid, acetapride, clothianisin, etc.), nitroganillin drugs (dinotefuran, etc.), organophosphorus insecticides (hoxime, tetraclocupinphos, fenitrothion, probetatanphos, etc.), pyrazole drugs (fibronyl, etc.), chlor Phenolic drugs (4-promo-2,5-dichlorophenol (BDCP), etc.), phenylpyrroles (chlorfenavir, etc.), hiba oil, turmeric, capric acid, Shea oil, palm oil, and the like.

  Next, the bag body 40 used for the ant-proof method of this embodiment is demonstrated using FIG.

  The bag body 40 includes a plurality of antifungal agent accommodating portions 42 formed by partitioning the inside thereof with a plurality of partition walls 41, and a lid portion 43 for sealing the inside of the bag body 40.

  Each of the termite-proofing agent accommodating portions 42 is formed in a cylindrical shape extending in one direction. Moreover, the positional relationship between the ant preventive agent accommodating portions 42 is arranged in a direction in which the ant preventive agent accommodating portion 42 extends, that is, in a direction orthogonal to the longitudinal direction. Then, the inside of each baggage 40 is sealed by the lid part 43 so that the baggage 40 is sealed by the lid part 43. It is enclosed inside the body 40.

  The material of the bag body 40 is dissolved by strong alkaline water (PH12 to PH14) such as water contained in fluid concrete, but is not dissolved in normal neutral water. In the form, one made of paper-making fibers and a water-soluble polymer is used.

  Any fiber for papermaking can be used as long as it is dispersed in water, and examples thereof include wood pulp fibers, non-wood pulp fibers, and rayon fibers. For example, kraft pulp or sulfite pulp for papermaking, dissolving pulp for chemical fiber, etc. are preferably used. However, vegetable fibers such as straw pulp and hemp pulp, synthetic fibers such as polyamide and polyester, glass fibers, asbestos, rock wool Inorganic fibers such as slag wool, silica wool and silica alumina wool can also be used.

  Examples of water-soluble polymers include synthetic products such as polyvinyl alcohol (PVA), sodium polyacrylate and polyethylene oxide, cellulose such as carboxymethyl cellulose (CMC), hydroxyethyl cellulose, ethyl cellulose, methyl cellulose and viscose, carboxymethyl starch Natural polymers such as starches such as dialdehyde starch, proteins such as glue, and the like can be used.

  As a more specific structure of the bag body 40, a material having a structure in which softwood bleached kraft pulp is 40 to 90% by weight, PVA is 10 to 50% by weight, and CMC is 2 to 15% by weight is used. The thickness of the bag body 40 can be 10 to 150 μm, preferably 30 to 80 μm. According to this structure, when it is made to contact with the water | moisture content contained in the concrete of the fluid state of PH12, the bag body 40 will be melt | dissolved in 30 seconds-300 seconds.

  The solubility of the bag 40 with respect to the pH of the aqueous solution can be appropriately set by changing the ratio of the above-described configuration. In general, softwood bleached kraft pulp does not dissolve in neutral water but dissolves in strong alkaline water, and has a relatively slow dissolution rate even in strong alkali, CMC is dissolved regardless of the pH of the aqueous solution, and its dissolution rate is relatively fast.

  That is, if the ratio of the softwood bleached kraft pulp is increased, it becomes difficult to dissolve in neutral water, and the dissolution rate in strong alkaline water can be decreased, and the ratio of PVA and CMC can be increased. For example, it is possible to make it soluble even if it is not strongly alkaline water, and to increase the dissolution rate.

  Next, an example of a method for constructing the ant proof structure at the base (that is, an ant proof method at the base) will be described with reference to FIGS.

  Step 1: In the ground 10 on which the foundation 11 is erected, a groove 13 is excavated on the inner side surface 12 of the foundation 11 (FIG. 3A). As described above, the groove 13 preferably has an inclined bottom surface in a direction that becomes deeper toward the inner surface 12 of the foundation 11, but the antifungal agent 30 can be filled even if the bottom surface is flat. In the method of the present invention, the excavation of the groove 13 may be omitted as appropriate.

  Step 2: The bag body 40 is arranged in a state of being in close contact with the inner side surface 12 of the foundation 11 and covering the upper surface of the groove 13 (FIG. 3B).

  Process 3: The concrete in a fluid state is poured into a region on the inner side of the bag body 40 in the soil area opposite to the foundation 11 with the bag body 40 interposed therebetween, and then hardened with time, so that the soil area is filled with soil. Concrete 14 is formed. At this time, the bag body 40 serves as a mold, so that a gap 20 is formed between the inner side surface 12 of the foundation 11 and the soil concrete 14 (FIG. 3C). Moreover, since the bag body 40 is dissolved by the moisture contained in the fluidized concrete, the termite-proofing agent 30 sealed in the inside of the termite-proofing agent containing portion 42 is filled in the groove 13 and the inside. The gap 20 is filled in a state of direct contact with the side surface 12 and the soil concrete 14 (FIG. 1).

  If the above method is adopted, the bag body 40 is dissolved by the water contained in the flowing concrete, and the bag body 40 is melted by bringing the water contained in the flowing concrete into contact with the bag body 40. With this, the gap formed between the inner side surface 12 and the soil concrete 14 in the state where the termite preventer 30 is in direct contact with the inner side surface 12 of the foundation 11 and the soil concrete 14. 20 can be disposed. Therefore, unlike the prior art, the step of removing the mold for securing the gap 20 and the step of putting the above-mentioned termite-proofing agent into the gap formed by removing the mold are not required, and labor for construction is reduced. It is possible to reliably interpose the termite-proofing agent 30 between the inner side surface 12 of the foundation 11 and the soil concrete 14 while reducing the above.

  Moreover, since dissolution of the bag body 40 is performed by moisture contained in the fluidized concrete injected inside the bag body 40, there is no need to bother to perform the process for melting the bag body 40. It becomes possible to further reduce labor.

  Further, the bag body 40 is dissolved by strong alkaline water (PH12 to PH14) such as water contained in the fluidized concrete, but is not dissolved in normal neutral water, and therefore exists in a normal environment. It is possible to prevent the bag body 40 from being melted by substantially neutral moisture due to moisture or the like, and to reliably melt the moisture contained in the flowing concrete. That is, it is possible to prevent the bag body 40 from dissolving before it comes into contact with moisture contained in the fluidized concrete.

  Furthermore, before the bag body 40 is arranged on the inner side surface 12 of the foundation 11, a groove having a bottom surface inclined so that the inner side surface 12 side is lowered along the inner side surface 12 of the foundation 11 is formed in the ground 10. When the bag body 40 is melted, the termite-proofing agent 30 can be surely brought into contact with the inner side surface 12 of the foundation 11 through the bottom surface. Therefore, the inner side surface 12 of the foundation 11 can be prevented more reliably, and the ant-proof effect can be obtained more effectively.

  Moreover, since the ant preventive agent 30 is accommodated in the bag body 40 in a state of being divided by the ant preventive agent accommodating portion 42, the ant preventive agent 30 is prevented from moving over a wide range in the bag body 40. Then, it is possible to prevent the bag body 40 from being greatly deformed by this movement. Accordingly, the shape retention of the bag body 40 can be improved, and the gap 20 can be formed in a more suitable shape. Therefore, it becomes possible to make the arrangement | positioning condition of the ant preventive agent 30 into a more suitable state.

  Further, since each of the termite-protecting agent accommodating portions 42 is arranged in a direction orthogonal to the direction (longitudinal direction) in which the termite-protecting agent accommodating portion 42 extends, the longitudinal direction is along the inner side surface 12 of the foundation 11, and By disposing the bag body 40 in a state in which the respective termiticide containing portions 42 are arranged in the vertical direction, even when the bag body 40 is disposed in a state of extending in the vertical direction, the antifungal agent 30 flows in the vertical direction. This can be prevented as much as possible, and the shape of the bag body 40 can be maintained.

  Other embodiments will be described below. In addition, about the thing of the same structure as the said embodiment, it attaches | subjects only the same code | symbol and the detailed description is abbreviate | omitted.

Second embodiment (see FIG. 4)
In the present embodiment, as shown in FIG. 4C, the groove 13 is not formed inside the foundation 11.

  The method of constructing such a structure is as follows.

  Process 1: The bag body 40 is arrange | positioned in the state closely_contact | adhered to the inner surface 12 of the foundation 11 (FIG. 4 (a)).

  Step 2: Concrete in a fluidized state is poured into a region inside the bag body 40, and then hardened after a while, thereby forming soil concrete 14 in the region. At this time, the bag body 40 serves as a formwork, so that a gap 20 is formed between the inner side surface 12 of the foundation 11 and the soil concrete 14 (FIG. 2B). Moreover, since the bag body 40 is dissolved by the moisture contained in the fluidized concrete, the ant preventive agent 30 enclosed in the ant preventive agent containing portion 42 is directly applied to the inner side surface 12 and the soil concrete 14. The gap 20 is filled in a state of contact with (Fig. 3 (c)).

Other Embodiments (1) In the present invention, it is not always necessary to form the partition wall 41 inside the bag body 40. For example, as in the configuration shown in FIG. 5, the cylindrical bags 45 that are closed at both ends extending in one direction (the depth direction in FIG. 5) are arranged in a direction perpendicular to the one direction. You may comprise so that it may be enclosed in the inside of the bag body 40 in the state divided | segmented by employ | adopting the structure which adhere | attaches and fills each bag 45 with the termiticide 30. FIG. Moreover, when forming the height of the soil concrete 14 low, it is not necessary to adhere | attach the bag 45 and to comprise the bag body 40, and you may comprise the bag body 40 by the bag 45 single-piece | unit.

  (2) The present invention may dissolve not only in water contained in the fluidized concrete but also in normal neutral water. However, in order to prevent dissolution by an external environment such as moisture, it is preferable that the solvent does not dissolve in neutral water.

  (3) The material of the bag body 40 does not need to be dissolved by moisture contained in the fluidized concrete, and may be any material having liquid solubility. Even when such a bag body 40 is used, there is no need to take a step of removing the mold once and putting an anti-anticide into the gap formed by this mold as in the conventional method. It is possible to improve. However, in the case of adopting such a configuration, after injecting the soil concrete 14, in order to dissolve the bag body 40, it is necessary to separately apply a liquid to the bag body 40, so in terms of improving the work efficiency, It is more preferable that it is soluble in the water contained in the fluid concrete.

  The bag body 40 is formed into a cylindrical shape having a thickness of 30 μm and a diameter of 24 mm using a sheet composed of 70% by weight of softwood bleached kraft pulp, 25% by weight of PVA, and 5% by weight of CMC. The termite-proofing agent 30 was filled.

  When the bag body 40 was brought into contact with moisture contained in the concrete in a fluid state of PH12, the bag body 40 was dissolved in about 20 seconds.

  Moreover, when this bag 40 was brought into contact with neutral water of PH7, it did not dissolve even after 24 hours.

  The bag body 40 was formed into a cylindrical shape having a thickness of 80 μm and a diameter of 24 mm using a sheet made of the same material as in Example 1, and the inside thereof was filled with the termite-proofing agent 30.

  When the bag body 40 was brought into contact with moisture contained in the concrete in a fluid state of PH12, the bag body 40 was dissolved in about 90 seconds.

  Moreover, when this bag 40 was brought into contact with neutral water of PH7, it did not dissolve even after 24 hours.
