Description

The present invention relates to a method of applying a anti-termite treatment foundation structure of the building.

  As a conventional technique related to the basic structure of a building, for example, Patent Document 1 below is known. In the basic structure of Patent Document 1, as shown in FIG. 18, an inner side surface 201 a of a frame-shaped outer peripheral foundation 201 that supports a building and an upper surface of a slab 205 that covers the ground E surrounded by the outer peripheral foundation 201. Insulating materials 210 and 211 are respectively constructed. An upper surface of the joint portion between the outer peripheral foundation 201 and the slab 205, that is, an inner corner portion P where the inner side surface 201 a of the outer peripheral foundation 201 and the upper surface of the slab 205 intersect with each other is filled with an ant protection material 209.

  Specifically, in Patent Document 1, a cutout portion obtained by obliquely cutting the portion is provided on the lower surface of the side end portion of the heat insulating material 211 corresponding to the inner corner portion P, and a region corresponding to the cutout portion. In addition, the above-mentioned termite-proof material 209 is filled.

JP 2005-213837 A

  According to the basic structure (FIG. 18) disclosed in Patent Document 1, even if a gap is generated at the joint between the outer peripheral foundation 201 and the slab 205, the termite-proofing material disposed at the inner corner P corresponding to the gap. By the effect of 209, white ants living in the soil are prevented from climbing upward from the gap through the outer periphery base 201, and the woody parts (bases, pillars, etc.) and heat insulating materials of the building may be damaged by white ants. Is prevented.

  However, the structure of Patent Document 1 in which the position of the termite-proof material 209 is filled in the position as shown in FIG. 18 has a problem that the maintainability deteriorates. For example, when a long period of time has passed since the completion of the building, the performance of the ant-proofing material 209 has deteriorated, so the ant-proofing chemical solution is supplied to the place where the ant-proofing material 209 is filled (ant-proofing treatment unit). It is desirable to maintain ant-proof performance by doing so. However, in order to perform such an operation of supplying an anti-anticide solution in the structure of Patent Document 1, it is necessary to remove the heat insulating materials 210 and 211 once, which complicates the operation.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a method for the anti-termite processor substructure to enable you to streamline operations for supplying anti-termite chemical .

In order to solve the above-mentioned problems, the present invention is a method for applying an ant-repellent treatment to a foundation structure including a foundation concrete that supports a building, wherein the shielding member covers the ant-proof treatment portion of the foundation concrete. And after attaching the shielding member, supplying the ant-proofing chemical liquid in a state where the shielding member is present, and moving the ant-proofing chemical liquid to the ant-proofing treatment section through a predetermined movement path. And a step of attaching a non-woven fabric on a movement path of the anti-anticide chemical before attaching the shielding member, and the anti-ant anti-chemical solution contains a surfactant for enhancing the permeability to the non-woven fabric. The content of the surfactant in the ant preventive chemical solution is set to 0. 0 so that the water absorption rate of the ant preventive chemical solution to the nonwoven fabric measured by the Bayrec method is 5 to 100 mm. Set to 2 to 5% by weight, characterized in that (claim 1).

  In the present invention, the term “ant-proof processing part” refers to a place where an ant-proof processing (predetermined processing for avoiding white ants) is performed. That is, in the foundation structure of a building, it is desirable to apply an ant-proofing treatment to a place where the white ants easily enter the foundation concrete so that the white ants do not crawl up from the floor base plate (in the soil) of the building and enter the building. The term “ant-proof processing part” refers to a place where such an ant-proof processing is performed.

  According to the present invention, during the operation of supplying the ant-preventive chemical solution, the ant-preventive chemical solution is surely prevented by impregnating the non-woven fabric with the ant-proof chemical solution while the shielding member is attached to the foundation concrete. It can be moved to the processing unit. Thereby, it is not necessary to make troublesome preparations such as removing the shielding member for supplying the ant-proofing chemical solution, and the workability of the work of supplying the ant-proofing chemical solution can be significantly improved. Moreover, the ant-proofing effect in the ant-proofing part is maintained over a long period of time by regularly supplying the ant-proofing chemical to the ant-proofing part, so that white ants can be reliably prevented from entering. Can do.

In particular, in the present invention, the surfactant for making it easy to permeate the ant preventive chemical into the nonwoven fabric is contained in the ant preventive chemical, so that the ant preventive chemical that has penetrated into the nonwoven fabric can be surely moved to the ant protection treatment part. It is possible to improve the efficiency of supplying the ant-proofing chemical.

  The basic concrete generally includes a vertical portion that is erected upward from the ground below the floor. In this case, the said ant-proofing process part can be made into the inner corner | angular part where the inner surface of the said upright part and the upper surface of another member cross | intersect (Claim 2).

  According to this configuration, the white ants do not crawl above the inner corners by the ant-proofing of the inner corners, so that the white ants can be effectively prevented from entering the building above the upright part. Can do.

  It is preferable that a solid or paste-like termite-proof material is disposed in the inner corner (Claim 3).

  According to this configuration, the white ants can be effectively prevented from entering above the inner corner portion by the termite-proof material disposed at the inner corner portion. In addition, for example, even when a considerable period of time has elapsed after the completion of the building, the ant-proofing effect at the inner corner is extended for a long time by supplying the ant-repellent chemical solution through the nonwoven fabric to the inner corner where the ant-proofing material is disposed. Therefore, the invasion of white ants can be reliably prevented.

As described above, according to the anti-termite treatment method based Ishizue構granulation of the present invention, it is possible to improve the efficiency of the work for supplying anti-termite chemical to anti-termite processor.

<First Embodiment>
(1) General description of foundation structure FIG. 1: is sectional drawing which shows the foundation structure concerning 1st Embodiment of this invention. As shown in the figure, a foundation concrete 100 that supports the building T is placed under the floor of the building T composed of houses and the like. The basic concrete 100 includes an outer peripheral foundation 1 and a slab 5.

  The outer periphery foundation 1 is a frame-shaped concrete material provided along the floor of the building T. In this embodiment, the outer periphery foundation 1 is a so-called cloth foundation having a reverse T-shape in cross section. That is, the outer peripheral foundation 1 is formed so as to protrude in the horizontal direction from the vertical part 2 formed to rise vertically upward from the ground E under the floor of the building T and from the lower end of the vertical part 2 embedded in the ground E. The footing 3 is integrally provided. On the upper surface of the upright part 2, a base Ta made of wooden squares or the like constituting the skeleton of the floor of the building T is fixed via anchor bolts or the like not shown.

  A heat insulating material 10 is attached to the side surface under the floor in the upright portion 2, that is, the inner side surface 2 a of the upright portion 2. The heat insulating material 10 is made of a resin material having excellent heat insulating properties such as foamed polystyrene and foamed urethane, for example, has a predetermined thickness in a direction orthogonal to the inner side surface 2a of the upright portion 2, and is substantially equal to the height of the upright portion 2. It is a plate-like member having the same height (see also FIGS. 2 and 3 to be described later). A plurality of such heat insulating materials 10 are prepared according to the area of the inner side surface 2a of the upright part 2, and are attached so as to be arranged in parallel along the inner side surface 2a (in a direction orthogonal to the paper surface in FIG. 1). ing. The heat insulating material 10 covers an inner corner portion C (ant-proof material 9), which will be described later, so as not to be seen from below the floor, and corresponds to a “shielding member” in the claims.

  The heat insulating material 10 is being fixed to the inner surface 2a of the upright part 2 via the adhesive agent, for example. When an adhesive is used for fixing the heat insulating material 10, it is preferable to use an adhesive in which an anti-anticide is kneaded. In addition, since the specific example of the chemical | medical agent which can be contained in an adhesive agent is fundamentally the same as the chemical | medical agent illustrated in description of the termite-proof material 9 mentioned later, description is abbreviate | omitted here.

  The slab 5 is a flat concrete material placed on the upper surface of the ground E. The slab 5 extends in the horizontal direction so as to cover the entire ground E under the floor, and its periphery is surrounded by the outer peripheral foundation 1 (upright portion 2).

  On the peripheral edge of the slab 5, a thickened portion 5a having a lower surface inclined so as to become lower in height as it approaches the outer peripheral foundation 1 is formed. The heat insulating material 10 is attached to the foundation concrete 100 such that the lower part is sandwiched between the thickened portion 5 a of the slab 5 and the outer peripheral foundation 1.

  A sheet material 7 is laid between the slab 5 and the ground E (the sheet material 7 is indicated by a one-dot chain line in the drawing). The sheet material 7 is made of a material having at least moisture resistance, more preferably a material having both moisture resistance and ant-proof properties. When the sheet material 7 is provided with ant-proofing properties, the material of the sheet material 7 may be a material in which an ant-proofing agent is kneaded. In addition, since the specific example of the chemical | medical agent kneaded in the sheet | seat material 7 is fundamentally the same as the chemical | medical agent illustrated in description of the termite-proof material 9 mentioned later, description is abbreviate | omitted here.

  The angle at which the inner side surface 2a of the upright portion 2 and the upper surface of the footing 3 intersect is referred to as an inner corner portion C below. The inner corner portion C is filled with an ant-proof material 9 having a property of preventing white ants (ant-proof property). That is, in order to prevent the white ants from entering upward (to the building T side) through the inner side surface 2a of the upright part 2, some kind of ant-proofing treatment is applied to the inner corner portion C which is the lower end of the inner side surface 2a. In this embodiment, the inner corner portion C is filled with the ant-proof material 9 as part of the ant-proofing process. Thus, the inner corner C filled with the termite-proof material 9 corresponds to the “ant-proof processing portion” described in the claims. Further, the footing 3 that forms the inner corner portion C in cooperation with the inner side surface 2a of the upright portion 2 corresponds to “another member” in the claims.

  The ant-proof material 9 is a solid or paste-like substance having ant-proof properties. Examples of the ant-proof material 9 include a paste-like resin composition in which an ant-proofing agent is kneaded, a resin molded body (film, pellet, plate, etc.) containing the ant-proofing agent, Any one of an inorganic powder or granule to which an ant drug is attached, and a pointed glass granule, or a combination of two or more thereof can be used.

  Further, the kind of the agent contained in the ant-proof material 9 is not particularly limited as long as it has ant-proofing properties. For example, pyrethroid-like drugs (silafluophene, etofenprox, etc.), pyrethroid drugs (bifenthrin, Cypermestone, deltamethrin, permethrin, permethrin, aresulin, tralomesulin, etc.), carbament drugs (proboxol, fenocarb, sebin, etc.), chlornicotil drugs (imidacloprid, acetapride, clothianisin, etc.), nitroganillin drugs (dinotefuran, etc.), organophosphorus insecticides Agents (Hoxime, Tetraclocupine Phos, Fenitrothion, Probetanfos, etc.), Pyrazoles (Fibronyl, etc.), Chlorphenols (4-Promo-2,5-dichlorophenol (BDCP), etc.) Phenyl pyrrole (Kurorufenabiru etc.), Hiba oil, turmeric, capric acid, coconut oil, palm oil, etc., can be used as the agent.

  2 to 4 are a perspective view and a cross-sectional view for explaining a specific shape and the like of the heat insulating material 10. In the following description, the surface on the upright part 2 side of the heat insulating material 10 is the back surface 11, the surface opposite to the upright part 2 (under the floor) of the heat insulating material 10 is the surface 13, and the lower surface of the heat insulating material 10 covering the footing 3 is shown. This is the bottom surface 12.

  A bottom groove 12 a is formed on the bottom surface 12 of the heat insulating material 10, with a corner portion where the bottom surface 12 and the back surface 11 intersect notched in a rectangular shape. Due to the presence of the bottom groove 12a, the inner corner portion C of the outer peripheral foundation 1 is surrounded by the upper surface of the footing 3, the inner side surface 2a of the upright portion 2 and the bottom groove 12a when the heat insulating material 10 is attached. A volume (rectangular cross-section) space is formed. The ant-proof material 9 is arranged in a state of being confined in a space corresponding to the bottom groove 12a (see FIG. 1). Instead of providing the rectangular bottom groove 12a as in the present embodiment, the cut surface is cut by tapering the corner of the heat insulating material 10 (the corner where the bottom surface 12 and the back surface 11 intersect). A space having a triangular cross section may be formed between the (inclined surface), the upper surface of the footing 3, and the inner surface 2 a of the upright portion 2.

  A plurality of guide holes 15 penetrating the heat insulating material 10 in the thickness direction are formed in the heat insulating material 10. Each guide hole 15 is provided so as to be aligned in the horizontal direction at the intermediate portion in the height direction (vertical direction) of the heat insulating material 10. In a state where the heat insulating material 10 is attached to the inner side surface 2 a of the upright portion 2 (FIG. 1), the inlet of the guide hole 15 opening in the surface 13 of the heat insulating material 10 is located higher than the upper surface of the slab 5. Yes.

  A non-woven fabric 20 is attached to the heat insulating material 10 so as to cover a part of the back surface 11 and the bottom surface 12 thereof. In addition, the nonwoven fabric 20 is represented by the thick solid line in FIG.1, FIG.2, FIG.4, and is represented by the gray coloring area | region in FIG. As shown in these figures, the non-woven fabric 20 has a range from the position slightly higher than the guide hole 15 in the back surface 11 to the bottom groove 12 a at the lower end (substantially lower half of the back surface 11), and the bottom of the bottom surface 12. It is attached so as to continuously cover the portion where the groove 12a is formed. The means for fixing the non-woven fabric 20 to the heat insulating material 10 is not particularly limited. For example, the non-woven fabric 20 may be fixed to the heat insulating material 10 using an adhesive, a screw, a tucker or the like, and the non-woven fabric 20 is attached to the inner surface. You may integrate the heat insulating material 10 and the nonwoven fabric 20 by shape | molding the heat insulating material 10 using a metal mold | die.

  Here, the nonwoven fabric 20 used in this embodiment is subjected to a hydrophilic treatment. This is for accelerating the penetration of the termite preventive chemical 9a, which will be described later, supplied during the maintenance work into the nonwoven fabric 20.

Specific examples of the material of the nonwoven fabric 20 include synthetic materials such as polyester resin (polyethylene terephthalate resin), polyethylene resin, polypropylene resin, polyamide resin, and composites thereof, natural materials such as silk, cotton, hemp, glass fiber, Examples thereof include inorganic materials such as carbon fibers. The nonwoven fabric 20 is manufactured by using any of these materials, for example, by a spun bond method or a melt blow method. It is preferable that the fabric weight of the nonwoven fabric 20 is 5-500 g / m < ² >, More preferably, it is 10-250 g / m < ² >, More preferably, it is 15-100 g / m < ² >.

  Examples of the hydrophilic treatment include a treatment for imparting a surfactant to the nonwoven fabric 20, a treatment for applying a hydrophilic resin to the nonwoven fabric 20, an etching treatment or a plasma treatment on the surface of the nonwoven fabric 20, a surface treatment using a photocatalyst such as titanium oxide, In addition, any one of surface treatments using an inorganic coating agent such as alkali silicate or a combination of two or more thereof is suitable.

  When a surfactant is applied to the nonwoven fabric 20 for hydrophilic treatment, for example, the surface of the nonwoven fabric 20 is impregnated by spraying or applying a surfactant, or a surfactant is kneaded as a material for the nonwoven fabric 20. It is recommended to use a rare synthetic material. As the application amount of the surfactant, it is preferable to add 0.02 to 5% by mass of the surfactant in terms of solid content with respect to the fiber, more preferably 0.05 to 3% by mass, and still more preferably 0. .1 to 2% by mass.

  As the surfactant, any one of anionic surfactants, cationic surfactants, nonionic surfactants, and zwitterionic surfactants or a combination of two or more thereof is suitable.

  Specific examples of anionic surfactants include fatty acid sodium, fatty acid potassium, sodium alphasulfo fatty acid ester, sodium alkylbenzene sulfonate, sodium alkyl sulfate ester, sodium alkyl ether sulfate, sodium alpha olefin sulfonate, and sodium alkyl sulfonate. Can be mentioned.

  Specific examples of the cationic surfactant include quaternary ammonium salts such as alkyltrimethylammonium salt, dialkyldimethylammonium salt, lauryltrimethylammonium salt, stearyltrimethylammonium salt, cetyltrimethylammonium salt, and distearyldimethylammonium salt. .

  Specific examples of nonionic surfactants include polyethylene glycol type surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, and polypropylene glycol ethylene oxide adducts, sucrose fatty acid ester sorbitan fatty acid ester, polyoxyethylene Examples include polyhydric alcohol surfactants such as sorbitan fatty acid esters and fatty acid alkanolamides.

  Specific examples of the zwitterionic surfactant include alkylamino fatty acid sodium, alkylbetaine, and alkylamine oxide.

  The nonwoven fabric 20 that has been hydrophilically treated by the above-described methods preferably has a water absorption rate of 5 to 100 mm, more preferably 10 to 100 mm, and even more preferably 20 to 100 mm, as measured by JIS L1907 (Birec method). . If the hydrophilic treatment is not performed, the water absorption speed is 0 mm.

As an example, a nonionic surfactant (polyoxyethylene alkyl ether) was applied to a nonwoven fabric made of polyethylene terephthalate resin having a basis weight of 35 g / m ² . The water absorption speed of the nonwoven fabric obtained in this case was 42 mm.

(2) Construction method Next, a method for constructing the above-described foundation structure will be described. As a premise of this explanation, it is assumed that the outer periphery foundation 1 (the upright part 2 and the footing 3) is already placed on the ground E.

  As an operation starting from this state, first, as shown in FIG. 5, a dug portion X is formed in a portion near the upright portion 2 in the ground E under the floor. The digging portion X is formed so that the width of the lower surface is substantially the same as the thickness of the heat insulating material 10 and the width of the upper surface is larger than the width of the lower surface. The outer periphery of the ground E after such a dug portion X is formed becomes an inclined surface y inclined so as to be separated from the upright portion 2 toward the upper side.

  Next, as shown in FIG. 6, the termite-proof material 9 is disposed at the inner corner C where the upper surface of the footing 3 exposed along with the formation of the digging portion X intersects the inner side surface 2 a of the upright portion 2. Further, the sheet material 7 is laid so as to cover the upper surface of the ground E under the floor. At this time, the peripheral portion of the sheet material 7 is laid so as to cover both the upper surface of the footing 3 exposed by the digging portion X and the ant-proof material 9 arranged in the inner corner portion C.

  Next, as shown in FIG. 7, a heat insulating material 10 (see FIGS. 2 and 3) in which a nonwoven fabric 20 is attached to the back surface 11 and the bottom surface 12 is prepared, and this is attached to the outer peripheral foundation 1. That is, the bottom surface 12 of the heat insulating material 10 is placed on the top surface of the footing 3, and the back surface 11 of the heat insulating material 10 is formed on the upright portion 2 using, for example, an adhesive (preferably an adhesive containing an anti-anticide). The heat insulating material 10 is attached so as to cover the inner side surface 2a of the upright part 2 by being fixed to the inner side surface 2a.

  When the heat insulating material 10 is attached as described above, the sheet material 7 laid on the upper surface of the footing 3 and the inner corner C are protected by the bottom surface 12 of the heat insulating material 10 as shown in FIG. Ant material 9 is covered from above. At this time, the termite-proof material 9 is confined in a space corresponding to the bottom groove 12a provided on the bottom surface 12 of the heat insulating material 10 (a space surrounded by the bottom groove 12a and the inner corner C). Further, a part of the termite-proof material 9 that does not fit in the space is stretched by being sandwiched between the bottom surface 12 of the heat insulating material 10 and the top surface of the footing 3.

  Next, the slab 5 is constructed so as to cover the ground E under the floor (see FIG. 1). At this time, the concrete flows into the space formed between the surface 13 of the heat insulating material 10 and the inclined surface y of the ground E in the digging portion X of the ground E, more specifically, in the digging portion X. The thickened portion 5a is formed in a portion corresponding to the portion X. Thereby, the lower part of the heat insulating material 10 is inserted | pinched between the thickened part 5a of the slab 5, and the inner surface 2a of the upright part 2, and the heat insulating material 10 is fixed more firmly. The thickness of the slab 5 is set such that the height of the upper surface of the slab 5 is lower than the guide hole 15 of the heat insulating material 10. For this reason, even after construction of the slab 5, the entrance (opening on the surface 13 side) of the guide hole 15 is not blocked.

(3) Maintenance work Next, the work procedure when carrying out the maintenance work for maintaining the ant-proof effect on the foundation structure constructed by the above method will be described.

  Since the white ants that live in the soil basically use the darkness as the range of action, when trying to enter the building T, for example, upward through a gap between the inner surface 2a of the upright part 2 and the back surface 11 of the heat insulating material 10. Try to crawl up. However, in the structure of this embodiment, since the termite-proof material 9 is disposed at the inner corner C of the upright portion 2 and the footing 3, basically, the termite-proof material 9 prevents the white ants from creeping up. The However, if the effect of the chemical contained in the ant-proofing material 9 is diminished due to aging, or if the volume of the ant-proofing material 9 shrinks due to drying, the white ants pass through the ant-proofing material 9 and go further upward. The foundation Ta of the building T can be damaged by the white ants (corrosion damage). In order to suppress such damage caused by white ants, it is effective to periodically supply the ant-protecting chemical 9a (FIG. 9) to the ant-proofing material 9.

  In the present embodiment, the above-described supply operation of the anti-anticide solution 9a can be performed with the heat insulating material 10 attached to the foundation concrete 100. An example is shown in FIG. FIG. 9 illustrates the case where the termite-proofing agent 9 a is introduced into the termite-proof material 9 using the syringe S. As the ant preventive chemical 9a, for example, a solution obtained by dissolving an ant preventive chemical in water or a solvent can be used. The same drugs as those used can be used.

  In order to supply the ant preventive chemical 9a, the operator enters the floor of the building T and injects the ant preventive chemical 9a into the heat insulating material 10 using the syringe S. More specifically, the needle tip of the syringe S in which the anti-anticide solution 9a is loaded is inserted into the inlet (opening on the surface 13 side) of the guide hole 15 of the heat insulating material 10, and in this state, the syringe S By pushing the piston, the ant-preventive chemical 9 a in the syringe S is injected into the guide hole 15. The termite preventive liquid 9 a injected into the guide hole 15 flows out from the outlet (opening on the back surface 11 side) of the guide hole 15 and is impregnated in the nonwoven fabric 20 attached to the back surface 11. The termite-proofing agent 9a impregnated in the nonwoven fabric 20 penetrates the entire nonwoven fabric 20 over time, and moves downward between the back surface 11 of the heat insulating material 10 and the inner surface 2a of the upright portion 2. Go. As a result, the anti-anticide solution 9a moves to the lower end of the nonwoven fabric 20, that is, the nonwoven fabric 20 that covers the bottom groove 12a of the heat insulating material 10, and finally the bottom groove 12a and the inner corner C It reaches the termite-proof material 9 arranged in the space surrounded by.

  In this way, in this embodiment, the ant protection chemical 9a injected from the guide hole 15 at the time of maintenance passes between the back surface 11 of the heat insulating material 10 and the inner side surface 2a of the upright portion 2 to form the inner corner C (ant proofing). Since it is necessary to move to the material 9), the ant-proof chemical 9a can permeate into the part corresponding to the movement path of the ant-proof chemical 9a, that is, the substantially lower half of the back surface 11 of the heat insulating material 10 and the bottom groove 12a. A nonwoven fabric 20 is attached. Since the nonwoven fabric 20 is attached on the movement path of the ant-proofing chemical solution 9a, the ant-proofing chemical solution 9a injected from the guide hole 15 is evenly distributed on the ant-proofing material 9 disposed in the inner corner C through the nonwoven fabric 20. Go around.

(4) Operation, etc. As described above, in the basic structure of the first embodiment, the inner corner C where the inner surface 2a of the upright portion 2 and the upper surface of the footing 3 intersect is the ant-proofing portion, and the inner corner An ant-proof material 9 is arranged in the part C. A heat insulating material 10 is attached to the inner side surface 2 a of the upright portion 2, and a bottom groove 12 a for confining the ant protection material 9 in the inner corner C is formed at the lower end (bottom surface 12) of the heat insulating material 10. Yes. Further, the non-woven fabric 20 subjected to hydrophilic treatment is attached to the heat insulating material 10 so as to continuously cover the bottom groove 12a at the lower end and the back surface 11 in a range from the bottom groove 12a to the upper portion of the predetermined distance. In addition, a guide hole 15 penetrating the heat insulating material 10 in the thickness direction is formed at a height position overlapping the nonwoven fabric 20 (a position slightly lower than the upper end of the nonwoven fabric 20). According to such a configuration, just by injecting the ant protection chemical 9a into the guide hole 15 provided in the heat insulating material 10, the ant protection chemistry 9a is moved through the nonwoven fabric 20 to the inner corner C (ant protection 9). Therefore, there is an advantage that the supply work of the anti-anticide solution 9a can be made more efficient.

  That is, in the first embodiment, when the termite preventive liquid 9a is injected into the guide hole 15 of the heat insulating material 10, the termite preventive liquid 9a flows out to the back surface 11 of the heat insulating material 10, and the outflow of the termite preventive chemical 9a is The inner surface 2a of the upright portion 2 and the upper surface of the footing 3 move to the inner corner C where the inner surface 2a of the upright portion 2 intersects through the nonwoven fabric 20 attached to the back surface 11 and the bottom groove 12a of the heat insulating material 10. In this way, the ant preventive chemical 9a can be moved to the inner corner C without making troublesome preparations such as removing the heat insulating material 10, so that the ant proof material 9 disposed in the inner corner C can be prevented. The ant drug solution 9a can be supplied efficiently, and the maintenance workability can be greatly improved. Moreover, since the ant-proofing effect in the inner corner C is maintained over a long period of time by supplying the ant-proofing agent 9a to the ant-proof material 9 periodically, the invasion of white ants through the inner corner C is prevented. It can be surely prevented.

  In particular, in the first embodiment, since the nonwoven fabric 20 is subjected to a hydrophilic treatment so that the anti-anticide solution 9a can easily penetrate into the nonwoven fabric 20, the anti-anticide solution 9a injected into the guide hole 15 is used as the nonwoven fabric 20. It is possible to reliably move to the inner corner portion C, and to supply the termite-proof chemical 9a to the termite-proof material 9 more efficiently.

  Further, since the nonwoven fabric 20 attached to the back surface 11 of the heat insulating material 10 is impregnated with the ant-proofing chemical 9a, the nonwoven fabric 20 itself exhibits the ant-proofing performance. It is possible to prevent white ants from entering between the inner surface 2a and the back surface 11 of the heat insulating material 10. Thereby, even if a white ant that broke through the ant protection material 10 arranged in the inner corner portion C exists, it is possible to more reliably prevent the white ant from moving further upward and entering the building T.

  In the first embodiment, the nonwoven fabric 20 is attached so as to cover the region below the guide hole 15 on the back surface 11 of the heat insulating material 10 and the bottom groove 12a of the heat insulating material 10, respectively. It is sufficient that the ant preventive chemical 9a supplied from the guide hole 15 is attached on the moving path when moving to the inner corner C (ant proof material 9). For this reason, the nonwoven fabric 20 should just cover the lower area | region (area | region below the guide hole 15) of the back surface 11 of the heat insulating material 10, and you may abbreviate | omit about the nonwoven fabric 20 of the part which covers the bottom groove | channel 12a. . Even in this case, it is considered that the termite-preventing chemical 9 a impregnated in the nonwoven fabric 20 reaches the termite-protecting material 9 through the lower end of the nonwoven fabric 20. However, in any case, the guide hole 15 needs to be provided at a height overlapping with the nonwoven fabric 20 in order to ensure that the nonwoven fabric 20 is impregnated with the anti-antibiotic solution 9a injected into the guide hole 15. In other words, the nonwoven fabric 20 is attached so as to cover at least the range from the lower end of the back surface 11 of the heat insulating material 10 to the exit of the guide hole 15 (opening on the back surface 11 side).

  Moreover, in the said 1st Embodiment, in order to move the termite chemical | medical solution 9a to the inner corner | angular part C in which the termite preventive material 9 is arrange | positioned, the terminator chemical | medical solution using the syringe S to the guide hole 15 provided in the heat insulating material 10 9a is injected, but not limited to the syringe S, it can be used as long as it can inject the anti-antibiotic solution 9a into the guide hole 15.

  Further, the guide hole 15 may not be provided in the heat insulating material 10 in advance. That is, at the time of construction of the building T, a heat insulating material not provided with a guide hole may be attached to the outer peripheral foundation 1, and a guide hole may be provided in the heat insulating material for the first time during maintenance for supplying the ant-proofing chemical 9a.

  Moreover, in the said 1st Embodiment, although the heat insulating material was not arrange | positioned on the upper surface of the slab 5, it is different from the heat insulating material 10 on the upper surface of the slab 5 like the prior art demonstrated using FIG. Materials may be placed.

  Moreover, in the said 1st Embodiment, the bottom face 12 of the heat insulating material 10 is partially notched, the bottom groove | channel 12a is formed, and an ant-proofing is carried out in the space enclosed by this bottom groove | channel 12a and the inner corner | angular part C of the outer periphery base 1. Although the material 9 is confined, the bottom groove 12a is not essential and may be omitted. When the bottom groove 12a is omitted, that is, when the bottom surface of the heat insulating material 10 is formed by a flat surface 12 ′ having no step as shown in FIG. 10, for example, between the bottom surface 12 ′ of the heat insulating material 10 and the footing 3 It is desirable to dispose the ant-proof material 9 evenly and arrange the ant-proof material 9 so as to fill the gap between them. The nonwoven fabric 20 is preferably attached so as to cover the back surface 11 of the heat insulating material 10 in the range below the guide hole 15 and the entire bottom surface 12 ′ of the heat insulating material 10. In the example of FIG. 10, the arrangement region of the termite-proof material 9 on the top surface of the footing 3 (between the bottom surface 12 ′ of the heat insulating material 10 and the top surface of the footing 3) is the “anticide-proof processing portion” referred to in the claims. It corresponds to.

  Moreover, in the said 1st Embodiment, the internal corner | angular part C of the outer periphery foundation 1 (what is called a cloth foundation) provided with the upright part 2 which supports the building T, and the footing 3 which protrudes in the horizontal direction from the lower end part, ie, the upright part 2. An example has been described in which the ant-proof material 9 is disposed at the inner corner C where the inner side surface 2a of the footing 3 intersects the upper surface of the footing 3 and the ant-proofing agent 9a is supplied to the ant-proof material 9. Such a structure is not limited to the example in which the ant-proof material 9 is disposed in the inner corner C as described above. For example, in the example shown in FIG. 11, the foundation concrete 101 has the outer peripheral foundation 1 (the upright part 2 and the footing 3) and the slab 105, and the peripheral part of the slab 105 extends to the inner side surface 2 a of the upright part 2. Yes. For this reason, an inner corner portion C ′ is formed by the upper surface of the slab 105 and the inner side surface 2 a of the upright portion 2. And the termite-proof material 9 is arrange | positioned in this inner corner | angular part C ', and the heat insulating material 10 is attached above it. In the example of FIG. 11, the inner corner portion C ′ where the termite-proof material 9 is disposed corresponds to the “ant-repellent treatment portion” described in the claims, and the inner corner portion C ′ cooperates with the inner side surface 2 a of the upright portion 2. The peripheral portion of the slab 105 that forms' corresponds to the “other member” in the claims, and the heat insulating material 10 that covers the termite-proof material 9 disposed in the inner corner portion C ′ is the “shielding member”. Is equivalent to.

  Moreover, as shown in FIG. 12, this invention is applicable also when attaching the heat insulating material 10 to the foundation structure where the ground E is not covered with the slab. That is, in the example of FIG. 12, the sheet material 7 is laid on the upper surface of the ground E, and the heat insulating material 10 is attached so as to sandwich the peripheral edge of the sheet material 7 with the ground E. An ant protection material 9 is disposed at an inner corner C ″ where the upper surface of the ground E and the inner side surface 2a of the upright part 2 intersect, and a heat insulating material 10 is attached so as to cover the ant protection material 9 from above. In the example of FIG. 12, the inner corner portion C ”corresponds to the“ ant-repellent treatment portion ”in the claims, the ground E corresponds to“ other members ”in the claims, and the heat insulating material 10 in the claims. This corresponds to the “shielding member”.

  Furthermore, although not shown in the drawings, the present invention can also be applied to a foundation structure called a so-called solid foundation in which the footing 3 is omitted from the outer circumference foundation 1. In this case, the foundation concrete includes a slab (bottom base concrete) that extends in a horizontal direction so as to cover the ground, and a vertical portion that is joined to the upper surface of the peripheral portion of the slab and is erected upward. Even in this case, the inner corner portion is formed by the upright portion and the slab as in the example of FIG. 11 described above, so that the ant-proof material can be applied to the inner corner portion (ant proofing treatment portion).

Second Embodiment
FIG. 13 is a diagram for explaining a second embodiment of the present invention. In this figure, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In 2nd Embodiment shown by FIG. 13, the heat insulating material 50 attached to the outer periphery base 1 is divided into 2 to the up-down direction. That is, the heat insulating material 50 includes a lower heat insulating material 50A disposed above the footing 3 and an upper heat insulating material 50B disposed above the lower heat insulating material 50A. The lower heat insulating material 50A is attached so as to cover a lower region of the inner side surface 2a of the upright portion 2, and the upper heat insulating material 50B covers an upper region than the lower heat insulating material 50A on the inner side surface 2a of the vertical portion 2. Is attached. Thereby, the inner side surface 2a of the upright part 2 is covered with the lower heat insulating material 50A and the upper heat insulating material 50B in almost the entire vertical direction.

  An ant-proof material 9 is disposed at the inner corner C of the outer peripheral foundation 1, that is, the inner corner C where the inner surface 2 a of the upright portion 2 and the upper surface of the footing 3 intersect. In the present embodiment, the inner corner C where the termite-proof material 9 is disposed corresponds to the “ant protection processing portion” in the claims, and the inner corner C is formed in cooperation with the inner side surface 2 a of the upright portion 2. The footing 3 to be formed corresponds to “another member” in the claims.

  A bottom groove 52a is formed on the bottom surface 52 of the lower heat insulating material 50A. The bottom groove 52a is formed by cutting out a corner portion where the bottom surface 52 and the back surface 51 intersect with each other in a rectangular shape. The termite-proof material 9 is arranged so as to be confined in the space surrounded by C. Thus, the lower heat insulating material 50A in the present embodiment covers the termite-proof material 9 arranged in the inner corner C so as not to be seen from the lower floor side, and therefore corresponds to the “shielding member” in the claims. .

  A nonwoven fabric 60 that has been subjected to the same hydrophilic treatment as that of the first embodiment is attached to the lower heat insulating material 50A. Specifically, the nonwoven fabric 60 is attached so as to cover the back surface 51, the bottom surface 52 (including the bottom groove 52a), the surface 53, and the top surface 54 of the lower heat insulating material 50A. Further, although not shown, when the direction perpendicular to the paper surface of FIG. 13 is the longitudinal direction of the lower heat insulating material 50A, the nonwoven fabric 60 is also attached to one side and the other side of the longitudinal direction. Thus, the nonwoven fabric 60 is attached so that all six surfaces of the rectangular parallelepiped lower heat insulating material 50A may be covered.

  In the present embodiment, when performing maintenance work to maintain the ant-proof effect, as shown in FIG. 14, the portion of the nonwoven fabric 60 exposed under the floor, more specifically, the surface 53 of the lower heat insulating material 50A. For example, the spray solution 70 is used to spray the anti-anticide solution 9a on the nonwoven fabric 60 located above the slab 5.

  The termite preventive liquid 9a sprayed from the sprayer 70 is impregnated in the exposed portion of the nonwoven fabric 60 described above, and penetrates the entire nonwoven fabric 60 over time. Thereby, the ant preventive chemical 9a penetrates to the non-woven fabric 60 located at the inner corner C of the outer peripheral foundation 1, and finally reaches the ant proof material 9 arranged at the inner corner C.

  As described above, in the second embodiment, the split-type heat insulating material 50 including the lower heat insulating material 50A and the upper heat insulating material 50B is attached to the outer peripheral foundation 1, and the entire surface of the lower heat insulating material 50A ( A non-woven fabric 60 subjected to hydrophilic treatment is attached to the back surface 51, the bottom surface 52, the front surface 53, and the top surface 54). For this reason, at the time of maintenance, the ant-proof chemical 9a can be reliably moved to the inner corner C by a simple method of impregnating the non-woven 60 attached to the lower heat insulating material 50A with the ant-proof chemical 9a. The ant-proof chemical 9a can be efficiently supplied to the ant-proof material 9 arranged in the inner corner C.

  Moreover, since the heat insulating material 50 is divided into upper and lower parts (having the lower heat insulating material 50A and the upper heat insulating material 50B), it is sufficient to attach the non-woven fabric 60 only to the lower heat insulating material 50A covering the termite-proof material 9. It is not necessary to attach the nonwoven fabric 60 to the upper heat insulating material 50B. For this reason, even if the entire surface of the lower heat insulating material 50A is covered with the nonwoven fabric 60, the use area of the nonwoven fabric 60 can be effectively suppressed.

  In the second embodiment, the non-woven fabric 60 is attached so as to cover the entire surface of the lower heat insulating material 50A. However, the non-woven fabric 60 has at least the ant-repellent chemical solution 9a sprayed from the sprayer 70 at the inner corner portion C (ant-proof portion). It only needs to be attached on the moving path when moving to the material 9). For this reason, the nonwoven fabric 60 is, for example, only the portion exposed below the floor (the portion above the upper surface of the slab 5) of the surface 53 of the lower heat insulating material 50A, the upper surface 54 and the back surface 51 of the lower heat insulating material 50. It may be one that covers. Even if it does in this way, the termite chemical | medical solution 9a spread | dispersed on the nonwoven fabric 60 of the part exposed under the floor moves to the inner corner | angular part C through the nonwoven fabric 60 of the part which covers the upper surface 54 and the back surface 51 of 50 A of lower side heat insulating materials.

  Further, the non-woven fabric 60 may be attached only to the surface 53 and the bottom surface 52 of the lower heat insulating material 50A. In this case as well, the ant-proof chemical 9a can be moved through the non-woven fabric 60 to the inner corner C (ant-proof material 9). . However, in this case, there is no non-woven fabric impregnated with the ant-preventive chemical 9a between the back surface 51 of the lower heat insulating material 50A and the inner surface 2a of the upright portion 2, so the non-woven fabric 60 is attached to the back surface 51. Compared to the second embodiment, the effect of preventing white ants from entering the building may be diminished. In that sense, it can be said that a pattern in which a nonwoven fabric is attached to the back surface 51 of the lower heat insulating material 50A is preferable.

  In the second embodiment, the sprayer 70 (FIG. 14) is used to impregnate the nonwoven fabric 60 with the anti-anticide solution 9a. However, as an alternative method, for example, the anti-anticide solution 9a is applied to the nonwoven fabric 60 by brushing or the like. May be impregnated.

  Moreover, in the said 2nd Embodiment, although the ant-proof material 9 has been arrange | positioned to the internal corner | angular part C where the inner surface 2a of the upright part 2 and the upper surface of the footing 3 cross | intersect similarly to previous 1st Embodiment, As described in the embodiment, the place where the termite-proof material 9 is disposed (the termite-proofing portion) is not limited to the inner corner C as described above. For example, as shown in FIG. 11, the termite-proof material 9 may be arranged at the inner corner C ′ of the upright portion 2 and the slab 105, or the termite-proof material 9 is arranged at the inner corner (not shown) of the so-called solid foundation. Alternatively, as shown in FIG. 12, the termite-proof material 9 may be disposed at the inner corner C ″ of the upright portion 2 and the ground E.

  In the second embodiment, as in the first embodiment, the bottom groove 52a is formed on the bottom surface 52 of the lower heat insulating material 50A. However, the bottom groove 52a is omitted and the bottom surface of the lower heat insulating material 50A is omitted. May be formed flat.

<Third Embodiment>
FIG. 15 is a diagram for explaining a third embodiment of the present invention. In the figure, the same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the third embodiment shown in FIG. 15, as in the first embodiment, the foundation concrete 102 composed of the outer peripheral foundation 1 and the slab 115 is placed on the ground E, but unlike the first embodiment, The heat insulating material is not attached to the outer periphery foundation 1. The slab 115 expands until the peripheral edge (thickened part 115a) abuts on the inner surface 2a of the upright part 2, and the peripheral edge of the slab 115 is laminated on the entire upper surface of the part of the footing 3 that projects to the floor lower side. ing.

  An ant-proof material 9 is disposed at the inner corner C of the outer peripheral foundation 1, that is, the inner corner C where the inner surface 2 a of the upright portion 2 and the upper surface of the footing 3 intersect. In the present embodiment, the inner corner C where the termite-proof material 9 is disposed corresponds to the “ant protection processing portion” in the claims, and the inner corner C is formed in cooperation with the inner side surface 2 a of the upright portion 2. The footing 3 to be formed corresponds to “another member” in the claims.

  The termite-proof material 9 arranged in the inner corner C is covered with the peripheral edge (thickened portion 115a) of the slab 115. Thus, since the peripheral part of the slab 115 in this embodiment covers the termite-proof material 9 arranged in the inner corner part C so as not to be seen from below the floor, it corresponds to a “shielding member” in the claims. .

  Between the outer periphery foundation 1 and the slab 115, the nonwoven fabric 80 to which the hydrophilic process similar to 1st Embodiment was given is attached. The nonwoven fabric 80 has a portion extending in the vertical direction along the inner side surface 2 a of the upright portion 2 and a portion covering the periphery of the termite-proof material 9. The former part is sandwiched between the inner surface 2 a of the upright part 2 and the peripheral edge of the slab 115, and the upper end thereof extends to a position higher than the upper surface of the slab 115. Thus, the nonwoven fabric 80 is attached in the state where the upper end part is exposed under the floor.

  In the third embodiment as described above, a portion of the non-woven fabric 80 exposed under the floor during maintenance for supplying the termite-proof chemical 9a (see FIG. 14 and the like) to the termite-proof material 9 disposed in the inner corner C. That is, the anti-anticide solution 9a is sprayed on the upper end portion of the nonwoven fabric 80 located above the upper surface of the slab 115 using a sprayer or the like. The sprayed ant preventive liquid 9a reaches the inner corner C by penetrating the entire nonwoven fabric 80. Thereby, the ant-proof chemical | medical solution 9a can be efficiently supplied to the ant-proof material 9 in the position (inner corner part C) which cannot be seen from under the floor.

<Fourth embodiment>
In each of the above-described embodiments (first to third embodiments), the solid or paste-like ant protection material 9 is arranged in the inner corners (C, C ′, C ″) as the ant protection treatment part. However, since the ant-proofing agent 9a can be supplied to the ant-proofing part through the nonwoven fabric (20, 60, 80), it is not essential to arrange the ant-proofing material 9 in the ant-proofing part. An example of the case where the ant protection material 9 is not disposed in the part will be described as a fourth embodiment.

  FIG. 16 is a diagram showing a basic structure according to the fourth embodiment of the present invention. In the fourth embodiment shown in FIG. 16, the ant-proofing treatment for the ant-proofing treatment part A set between the peripheral part of the slab 105 and the ground E is performed by impregnating the nonwoven fabric 90 exclusively with the ant-proofing chemical solution 9a. To do.

  Specifically, in the fourth embodiment, a non-woven fabric 90 that has been subjected to the same hydrophilic treatment as that of the first embodiment is attached around the periphery of the slab 105. The nonwoven fabric 90 has a portion extending in the vertical direction along the inner side surface 2a of the upright portion 2, and a portion extending in the horizontal direction along the upper surface of the ground E in the ant-proofing treatment portion A. The former part is sandwiched between the inner surface 2 a of the upright part 2 and the peripheral part of the slab 105, and the upper end thereof extends to a position higher than the upper surface of the slab 105. The latter part, that is, the part arranged in the ant protection processing part A is sandwiched between the lower surface of the peripheral part of the slab 105 and the ground E. Only the nonwoven fabric 90 exists in the ant-proofing part A, and the ant-proofing material 9 used in each of the previous embodiments is not arranged.

  In the fourth embodiment, the slab 105 that covers the ant protection processing part A so as not to be seen from below the floor corresponds to a “shielding member” in the claims.

  Thus, in 4th Embodiment, since the ant-proof material 9 is not arrange | positioned at the ant-proof processing part A, from the beginning of constructing the building T, the ant-proof processing part A is ant-proofed using the nonwoven fabric 90. It is good to keep. That is, the anti-anticide solution 9a (see FIG. 14 and the like) is sprayed on a portion of the nonwoven fabric 90 exposed under the floor, that is, on the upper end portion of the nonwoven fabric 90 positioned above the upper surface of the slab 105 using a sprayer or the like. The sprayed ant-repellent chemical 9a reaches the ant-repellent treatment part A by penetrating the entire nonwoven fabric 90. As a result, the ant-protecting chemical solution 9a can be supplied to the ant-repellent treatment part A that cannot be seen from under the floor, and the ant-proof treatment part A can be efficiently treated.

  In addition, when a considerable period of time has passed after the completion of the building T, the ant-proofing effect in the ant-proofing treatment part A is reduced. The ant-proofing chemical 9a is supplied to the ant-proofing processing part A. Thereby, the ant-proof effect in the ant-proof processing part A can be maintained over a long period of time.

<Fifth Embodiment>
Furthermore, another example in which the ant-proof material 9 is not arranged in the ant-proof processing section will be described as a fifth embodiment of the present invention with reference to FIG. In 5th Embodiment shown by FIG. 17, the piping Z is arrange | positioned so that the slab 115 may be penetrated to an up-down direction. And between the lower surface of the slab 115 in the penetration part of this piping Z, and the ground E is set as the ant-proof process part B. FIG.

  A non-woven fabric 91 that has been subjected to the same hydrophilic treatment as that of the first embodiment is attached to the through portion of the pipe Z. The nonwoven fabric 91 has a portion extending in the vertical direction along the peripheral surface of the pipe Z, and a portion extending in the horizontal direction along the upper surface of the ground E in the ant-proofing treatment portion B. The former part is sandwiched between the peripheral surface of the pipe Z and the slab 115, and its upper end extends to a position higher than the upper surface of the slab 115. The latter part, that is, the part disposed in the ant-proofing part B, is sandwiched between the lower surface of the slab 115 surrounding the pipe Z and the ground E. Only the non-woven fabric 91 is present in the ant-proofing treatment part B, and the ant-proofing material 9 used in the previous embodiments is not arranged.

  In the fifth embodiment, the slab 115 that covers the ant protection part B so as not to be seen from below the floor corresponds to a “shielding member” in the claims.

  Thus, in 5th Embodiment, since the ant-proof material 9 is not arrange | positioned in the ant-proof processing part B, the ant-proof processing part B is ant-proofed using the nonwoven fabric 91 from the beginning of constructing the building T. It is good to keep. That is, the termite-proofing agent 9a (see FIG. 14 and the like) is sprayed on the portion of the nonwoven fabric 91 exposed under the floor, that is, on the upper end portion of the nonwoven fabric 91 located above the upper surface of the slab 115 using a sprayer or the like. The sprayed ant-repellent chemical 9a reaches the ant-repellent treatment part B by penetrating the entire nonwoven fabric 91. Thereby, the ant-proof chemical | medical solution 9a can be supplied to the ant-proof processing part B in the position which cannot be seen from under the floor, and the said ant-proof processing part B can be processed efficiently.

  In addition, when a considerable period of time has passed after the completion of the building T, the ant-proofing effect in the ant-proofing treatment part B is reduced. The ant-proofing chemical solution 9a is supplied to the ant-proofing processing part B. Thereby, the ant-proof effect in the ant-proof processing part B can be maintained over a long period of time.

<Other embodiments>
In the 1st-5th embodiment mentioned above, in order to improve the permeability | transmittance to the nonwoven fabric (20, 60, 80, 90, 91) of the ant-proofing chemical | medical solution 9a, the nonwoven fabric which performed the hydrophilic treatment was used. However, the method for increasing the value is not limited to this. For example, it is conceivable to use a liquid containing a surfactant for enhancing the permeability to the nonwoven fabric as the anti-anticide solution 9a. The surfactant is not particularly limited as long as it has an effect of increasing the permeability of the anti-anticide solution 9a. For example, the same surfactant as mentioned in the description of the hydrophilic treatment of the nonwoven fabric should be used. Can do.
