<Embodiment 1>
(1) General Description of Insulated Underfloor Structure FIG. 1 is a cross-sectional view showing an insulated underfloor structure according to the first embodiment of the present invention. As shown in the figure, an outer peripheral foundation 1 made of a concrete material formed in a frame shape so as to correspond to the planar shape of the building T is placed in the lower floor portion of the building T made of a house or the like. The building T is supported from below by the outer peripheral foundation 1. The floor portion of the building T includes a base Ta made of wooden squares or the like constituting the skeleton, and this base Ta is fixed to the upper surface of the outer peripheral foundation 1 via an anchor bolt or the like not shown. Yes.

  A footing 2 extending in the horizontal direction in a state of being embedded in the ground E is integrally formed at the lower end portion of the outer periphery foundation 1, and the outer periphery foundation 1 and the footing 2 form a so-called inverted T-shaped cross section. A fabric foundation is formed. In addition, since the footing 2 is a member located under the heat insulating material 10 mentioned later, it corresponds to the "lower member" concerning this invention.

  A heat insulating material 10 is attached to the side surface under the floor of the outer peripheral foundation 1, that is, the inner side surface 1 a of the outer peripheral foundation 1. The heat insulating material 10 is made of, for example, a resin material having excellent heat insulating properties such as foamed polystyrene and foamed urethane, has a predetermined thickness in a direction orthogonal to the inner side surface 1a of the outer peripheral foundation 1, and is almost equal to the height of the outer peripheral foundation 1. It is a plate-shaped member having the same height (see also FIGS. 2 to 5 described later). On the inner side surface 1a of the outer peripheral foundation 1, a plurality of the heat insulating materials 10 are attached in parallel (in a direction perpendicular to the paper surface in FIG. 1) in accordance with the area.

  The said heat insulating material 10 is being fixed to the inner surface 1a of the outer periphery base 1 through 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 preventer 9 mentioned later, description is abbreviate | omitted here.

  The underfloor portion of the building T surrounded by the outer peripheral foundation 1 and the heat insulating material 10 is laid with earthen concrete 5 made of a plate-like concrete material extending in the horizontal direction. The upper surface of E is covered.

  A thickened portion 5a having a lower surface inclined so as to become lower in height as it approaches the outer peripheral foundation 1 (heat insulating material 10) is formed at the peripheral portion of the soil concrete 5. The heat insulating material 10 is attached to the outer peripheral foundation 1 in such a state that a lower portion thereof is sandwiched between the thickened portion 5 a of the soil concrete 5 and the outer peripheral foundation 1.

  Between the soil concrete 5 and the ground E, an ant-proof sheet 7 made of a sheet-like body into which an ant-proofing agent is kneaded is laid. The ant-proof sheet 7 extends so as to cover a wider area than the soil concrete 5, and a part thereof protrudes to the outside of the soil concrete 5. For this reason, between the said heat insulating material 10 and the footing 2, the peripheral part of the said ant-proof sheet | seat 7 which protruded from the soil concrete 5 is inserted | pinched. In addition, since the specific example of the chemical | medical agent which can be contained in the termite prevention sheet 7 is fundamentally the same as the chemical | medical agent illustrated in description of the termite prevention agent 9 mentioned later, description is abbreviate | omitted here.

  An inner corner portion C, which is a portion where the inner side surface 1a of the outer peripheral base 1 and the upper surface of the footing 2 intersect, is filled with an anti-anticide 9 having a function of preventing white ants from entering (ant-preventing function).

  The above-mentioned ant-proofing agent 9 is not particularly limited as long as it has an ant-proofing function and has a certain shape-retaining property. For example, a paste-like resin into which an ant-proofing agent is incorporated Composition, resin molded body containing an anti-anticide (film, pellet, plate, etc.), particulate or powdery inorganic substance adhered to an anti-ant, or a small piece of glass Further, a combination of two or more of these can be used as the above-mentioned ant-protecting agent 9.

  In addition, the kind of the drug contained in the anti-anticide 9 is not particularly limited as long as it has an anti-ants function. For example, pyrethroid-like drugs (silafluophene, etofenprox, etc.), pyrethroid drugs (bifenthrin) , Cypermestone, Deltamethrin, Permethrin, Permethrin, Aresulin, Tralomethrin, etc., Carbament drugs (Provoxl, Fenobucarb, Sebin, etc.), Chlornicotyl drugs (Imidacloprid, Acetapride, Clothianisin, etc.), Nitroganillin drugs (Dinotefuran, etc.), Organic phosphorus Insecticides (Hoxime, Tetraclocupinphos, Fenitrothion, Probetanfos etc.), Pyrazole drugs (Fibronyl etc.), Chlorphenol drugs (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 and 3 are perspective views showing the heat insulating material 10 alone, FIG. 4 is a rear view of the heat insulating material 10 alone, and FIG. 5 is a cross-sectional view taken along the line VV in FIG. In FIG. 5, the outer peripheral foundation 1 and the footing 2 are indicated by imaginary lines. In the following description, the surface on the outer peripheral foundation 1 side of the heat insulating material 10 is the back surface 11, the surface opposite to the outer peripheral foundation 1 of the heat insulating material 10 (under the floor) is the surface 13, and the lower surface of the heat insulating material 10 covering the footing 2 is shown. This is the bottom surface 12.

  At the corner of the bottom surface 12 of the heat insulating material 10 on the outer peripheral foundation 1 side, that is, at the corner where the bottom surface 12 and the back surface 11 of the heat insulating material 10 intersect, a bottom obtained by removing the bottom surface 12 of the heat insulating material 10 by a predetermined depth. A groove 12a is formed. Due to the existence of the bottom groove 12 a, a space having a predetermined volume is formed between the upper surface of the footing 2 and the bottom surface 12 of the heat insulating material 10 in the inner corner portion C of the outer peripheral foundation 1. The termite-proofing agent 9 is arranged so as to be confined in a space corresponding to the bottom groove 12a (see FIG. 1).

  The heat insulating material 10 extends along the back surface 11 of the heat insulating material 10 from the guide hole 15 penetrating the heat insulating material 10 in the thickness direction, and the exit of the guide hole 15 opened in the back surface 11 of the heat insulating material 10. A guide groove 16 reaching the bottom surface 12 of the heat insulating material 10 is formed. The guide hole 15 and the guide groove 16 serve to guide the termite-proofing agent (maintenance termite-proofing agent) to be replenished during maintenance work described later to the position of the termite-proofing agent 9 (here, the inner corner C). Yes, it corresponds to “guidance means” according to the present invention.

  The guide hole 15 is provided in an intermediate portion in the height direction of the heat insulating material 10 (the direction along the inner side surface 1a of the outer peripheral foundation 1), and the inlet of the guide hole 15 opened to the surface 13 of the heat insulating material 10 is It is located higher than the upper surface of the soil concrete 5.

  The guide groove 16 branches from a formation portion of the exit of the guide hole 15 (opening on the back surface 11 side) from a vertical groove portion 17 extending downward along the back surface 11 of the heat insulating material 10 and a lower end of the vertical groove portion 17. A plurality of (three in the illustrated example) branching groove portions 18 extending radially to the bottom surface 12 of the heat insulating material 10 are provided. Each branch groove portion 18 extends from the lower end of the vertical groove portion 17 to the bottom surface 12 of the heat insulating material 10, and the lower end portion of each branch groove portion 18 communicates with a bottom groove 12 a provided on the bottom surface 12 of the heat insulating material 10. . As described above, the guide groove 16 composed of the branch groove 18 and the vertical groove portion 17 communicates the outlet of the guide hole 15 opened on the back surface 11 of the heat insulating material 10 and the bottom groove 12a of the heat insulating material 10 with each other. Is provided.

  The heat insulating material 10 having the above structure can be formed, for example, as follows. First, a raw material such as expanded polystyrene is poured into a molding die to form a material for the heat insulating material 10. A guide groove 16 and a bottom groove 12a are already formed in the material of the heat insulating material 10 according to the shape of the cavity of the molding die. Finally, the heat insulating material 10 is drilled to form a guide hole 15 at a position corresponding to the upper end of the guide groove 16. By the above, the heat insulating material 10 which has the guide hole 15, the guide groove 16, and the bottom groove 12a can be shape | molded. In addition, after cutting the raw material of the heat insulating material 10 obtained by continuous molding such as extrusion molding to a desired dimension, the guide hole 15, the guide groove 16, and the bottom groove 12a may be formed by machining.

(2) Construction method Next, a method for constructing the above-described heat insulating floor structure will be described. As a premise of this description, it is assumed that the outer peripheral foundation 1 and the footing 2 have already been placed on the ground E.

  As an operation starting from the above state, first, as shown in FIG. 6, a dug portion X is formed in a portion of the ground E near the outer periphery foundation 1 in the lower floor portion, and a part of the upper surface of the footing 2 is exposed. At this time, the width of the dug portion X is set so as to increase toward the upper side, and the peripheral surface of the ground E is formed in an inclined shape.

  Next, as shown in FIG. 7, the termite preventer 9 is disposed at the inner corner C where the inner surface 1 a of the outer peripheral foundation 1 and the upper surface of the footing 2 intersect, and the upper surface of the ground E in the lower floor portion is covered. The ant sheet 7 is laid. At this time, the peripheral portion of the ant-proof sheet 7 is laid so as to cover both the upper surface of the footing 2 exposed by the digging portion X (FIG. 6) and the ant-proofing agent 9 disposed at the inner corner C. The In addition, the number of the ant-proof sheets 7 used in the laying work here is not limited to one. When using a plurality of the ant-proof sheets 7, for example, a relatively wide area including a strip-shaped ant-proof sheet 7 prepared to cover only a portion relatively close to the outer peripheral foundation 1 and the center portion of the ground E. It is preferable that the rectangular ant protection sheet 7 prepared for covering is partially laid and overlapped.

  Next, as shown in FIG. 8, the heat insulating material 10 is attached to the outer peripheral foundation 1. That is, the heat insulating material 10 is attached so as to cover the inner surface 1a of the outer peripheral foundation 1 and the upper surface of the footing 2 by fixing the back surface 11 of the heat insulating material 10 to the inner surface 1a of the outer peripheral foundation 1 through an adhesive or the like. . When an adhesive is used for fixing the heat insulating material 10, it is preferable to use an adhesive containing an anti-anticide.

  When the heat insulating material 10 is attached as described above, as shown in FIG. 9, the heat insulating material 10 is disposed on the ant-proof sheet 7 laid on the upper surface of the footing 2 and the inner corner C by the bottom surface 12 of the heat insulating material 10. The anti-anticide 9 is covered from above. At this time, the termite-proofing agent 9 is accommodated 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), and in this space. A part of the termite-proofing agent 9 that cannot be contained is stretched by being sandwiched between the bottom surface 12 of the heat insulating material 10 and the top surface of the footing 2.

  Next, the soil concrete 5 is constructed so as to cover the ground E in the lower floor portion (see FIG. 1). At this time, the concrete also flows into the digging portion X (FIG. 6) formed in the peripheral portion of the ground E in the lower floor portion, and the thickened portion 5a is formed in a portion corresponding to the digging portion X. Thereby, the lower part of the heat insulating material 10 is inserted | pinched between the thickened part 5a of the soil concrete 5, and the inner surface of the outer periphery foundation 1, and the heat insulating material 10 is fixed more firmly. In addition, the thickness of the soil concrete 5 is set such that the height of the upper surface of the soil concrete 5 is lower than the guide hole 15 of the heat insulating material 10. For this reason, even after construction of the interstitial concrete 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 performing maintenance for maintaining the ant-preventive effect for the heat insulating floor structure constructed by the above method will be described.

  Since the white ants in the soil basically use the darkness as the range of action, when trying to enter the building T, for example, through the gap between the inner surface 1a of the outer periphery foundation 1 and the back surface 11 of the heat insulating material 10 upwards Try to crawl up. However, in the structure of the present embodiment, since the termite preventer 9 is disposed at the inner corner C of the outer peripheral foundation 1 and the footing 2, the termite preventer 9 basically prevents the white ants from creeping up. The However, if the effect of the agent contained in the ant repellent 9 diminishes due to deterioration over time, or if the volume of the ant repellent 9 shrinks due to drying, the white ants pass through the ant repellent 9 and move 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 necessary to periodically replenish the position of the above-mentioned termite preventer 9 (in this case, the inner corner C) with the termite inhibitor. Hereinafter, the termite-proofing agent replenished at the time of such maintenance is referred to as “maintenance termite-proofing agent”.

  In this embodiment, the replenishment work of the maintenance termiticide as described above can be performed from the surface 13 side (that is, the under floor side) of the heat insulating material 10 while the heat insulating material 10 is attached to the outer peripheral foundation 1. It is. An example is shown in FIG. FIG. 10 illustrates the case where the maintenance termite-proofing agent 9 ′ is introduced into the inner corner C using the syringe 20. The maintenance ant preventive agent 9 ′ may be the same as or different from the ant preventive agent 9 arranged at the inner corner C from the beginning. For example, when the initial termite-proofing agent 9 is rich in fluidity, the same one can be used as the maintenance termite-proofing agent 9 '. On the other hand, if the initial fluidity of the termite-proofing agent 9 is low, another termite-proofing agent having a high fluidity may be used as the maintenance termiticide 9 '. For example, a ant-preventing chemical dissolved in water or a solvent may be used as the maintenance ant-preventing agent 9 '.

  In the example of FIG. 10, when replenishing the maintenance termite-proofing agent 9 ′, the operator enters the lower floor portion of the building T and uses the syringe 20 from the surface 13 side (lower floor side) of the heat insulating material 10. Inject the termite-proofing agent 9 'for maintenance. Specifically, the needle tip of the syringe 20 in which the maintenance terminator 9 ′ is loaded is inserted into the entrance (opening on the surface 13 side) of the guide hole 15 of the heat insulating material 10, and in this state, the syringe By pushing the 20 piston, the maintenance termite-proofing agent 9 ′ in the syringe 20 is injected into the guide hole 15. The maintenance insecticide 9 ′ injected into the guide hole 15 flows into the guide groove 16 formed in the back surface 11 of the heat insulating material 10 continuously with the outlet of the guide hole 15, and through this guide groove 16 the heat insulating material. It flows down to the bottom surface 12 of 10.

  Here, as shown in FIG. 2 and FIG. 4, the guide groove 16 has a longitudinal groove portion 17 continuous with the outlet of the guide hole 15 and a plurality of branch groove portions 18 branched from the lower end thereof. The maintenance ant preventive agent 9 ′ flowing out from the outlet of the hole 15 flows downward while being divided into a plurality of paths through the longitudinal groove portion 17 and the plurality of branch groove portions 18.

  The maintenance termiticide 9 ′ injected through the guide hole 15 and the guide groove 16 as described above flows into the bottom groove 12a provided on the bottom surface 12 of the heat insulating material 10, and the bottom groove 12a and the outer periphery The space between the base 1 and the inner corner C of the foundation 1 reaches the ant-repellent agent 9 filled from the beginning, and stays in the gap between the bottom surface 12 of the heat insulating material 10 and the footing 2. In addition, although the ant-proof sheet 7 is laid between the ant-proofing agent 9 and the heat insulating material 10, the maintenance ant-proofing agent 9 ′ that has flowed in through the guide groove 16 is provided between the ant-proofing sheet 7 and the outer periphery foundation. It reaches the original ant protection agent 9 without any problem through a gap with the inner side surface 1a of 1.

(4) Operational effects and the like As described above, in the first embodiment, in the heat insulating underfloor structure in which the inner side surface 1a of the frame-shaped outer peripheral foundation 1 that supports the building T is covered with the heat insulating material 10, Such a characteristic configuration was adopted.

  That is, in the said 1st Embodiment, the ant-proofing agent which has an ant-proof function in the inner corner | angular part C formed by the inner surface 1a of the said outer periphery base 1, and the upper surface of the footing 2 (lower side member) which cross | intersects the said surface. 9 is arranged, and the heat insulating material 10 is attached so as to cover the termite-proofing agent 9 from above and along the inner side surface 1a of the outer peripheral foundation 1. The heat insulating material 10 is provided as a guiding means for guiding the maintenance ant preventive agent 9 ′ replenished from the surface 13 side (under the floor side) of the heat insulating material 10 during maintenance to the inner corner C of the outer peripheral foundation 1. And a guide groove 16 extending from the outlet of the guide hole 15 along the back surface 11 of the heat insulating material 10 and reaching the bottom surface 12 of the heat insulating material 10.

  According to such a configuration of the first embodiment, it is possible to further facilitate the replenishment work of the maintenance termiticide 9 '. That is, in the first embodiment, the guide hole 15 provided in the heat insulating material 10 and the guide are provided when it is desired to supplement the inner corner C of the outer periphery foundation 1 on which the termite preventer 9 is disposed with the maintenance termite preventive 9 '. Through the groove 16 (guide means), it is possible to easily and surely replenish the maintenance termiticide 9 ′ from the surface 13 side of the heat insulating material 10. This eliminates the need for troublesome preparations such as removing the heat insulating material 10 in order to replenish the maintenance termite-proofing agent 9 ′, and can greatly improve maintenance workability. In addition, the termite-proofing agent 9 'is periodically replenished to the termite-proofing agent 9 arranged at the inner corner portion C of the outer peripheral foundation 1, so that the termite-proofing effect at the inner corner portion C is extended for a long time. Therefore, it is possible to reliably prevent white ants from entering through the inner corner C.

  In particular, in the first embodiment, as a guide means for guiding the maintenance termite-proofing agent 9 ′ to the inner corner C of the outer periphery foundation 1, the guide hole 15 penetrating the heat insulating material 10 and the outlet thereof to the back surface 11 of the heat insulating material 10. Since the guide groove 16 extending along the guide line is provided, the maintenance ant preventive agent 9 ′ can be reliably introduced into the inner corner C through the guide hole 15 and the guide groove 16 during maintenance.

  More specifically, in the first embodiment, the guide groove 16 provided on the back surface 11 of the heat insulating material 10 has a vertical groove portion 17 extending downward from the outlet of the guide hole 15 along the back surface 11 of the heat insulating material 10. And a plurality of branch groove portions 18 branched from the lower end of the vertical groove portion 17 and extending to the bottom surface 12 of the heat insulating material 10. According to such a configuration, since the maintenance ant preventive 9 'is divided into a plurality of paths and introduced into the inner corner C of the outer periphery foundation 1, the above-mentioned ant preventer 9 disposed at the inner corner C is added to the above-mentioned The maintenance ant preventive agent 9 'can be replenished evenly, and the reinforcement effect of the ant proof function can be effectively prevented from greatly varying depending on the place.

  Note that, in the first embodiment, when introducing the maintenance termiticide 9 ′ into the inner corner C through the guide hole 15 and the guide groove 16 of the heat insulating material 10, the maintenance termiticide 9 ′ is used by using the syringe 20. However, as long as it can inject the maintenance termiticide 9 ′ into the guide hole 15, it can be used as appropriate without being limited to the syringe 20.

  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 agent 9 is accommodated, 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 constituted by a flat surface 12 ′ having no step as shown in FIG. 11, for example, the bottom surface 12 ′ of the heat insulating material 10 and the footing 2 It is desirable to arrange the ant-repellent agent 9 so as to evenly stretch the ant-repellent agent 9 between them and fill the gap between them. Even if it does in this way, the penetration | invasion of the white ant through the clearance gap between the inner surface 1a of the outer periphery foundation 1 and the heat insulating material 10 can be prevented reliably. In addition, when the maintenance terminator 9 ′ is filled through the guide hole 15 and the guide groove 16 during maintenance, the function of the part of the terminator 9 in the portion located at the inner corner C of the outer peripheral foundation 1 is particularly enhanced. Thus, the ant-proof effect is maintained for a long time.

  Of course, as described above, the termite-proofing agent 9 may be intensively arranged only in the inner corner portion C while omitting the bottom groove 12a of the heat insulating material 10. In this case, the termite preventer 9 is provided between the back surface 11 (near the lower end of the back surface 11) of the portion near the inner corner portion C and the outer peripheral foundation 1 or the bottom surface of the portion of the heat insulating material 10 near the inner corner portion C. By being sandwiched between 12 'and the footing 2, the function of preventing the entry of white ants is exhibited.

  Moreover, in the said 1st Embodiment, although the heat insulating material was not arrange | positioned on the upper surface of the soil concrete 5, it is different from the heat insulating material 10 on the upper surface of the soil concrete 5 similarly to the prior art demonstrated using FIG. A heat insulating material may be arranged.

  Moreover, in the said 1st Embodiment, the inner corner | angular part C of the so-called cloth foundation provided with the outer periphery foundation 1 which supports the building T, and the footing 2 provided in the lower end part, ie, the inner surface 1a and the footing of the outer periphery foundation 1 In the example described above, the termite-proofing agent 9 is arranged at the inner corner C where the upper surface of 2 is intersected, and the maintenance-purpose termiticide 9 ′ is replenished to the inner corner C where the termite-proofing agent 9 is arranged. The structure to which the invention can be applied is not limited to the example in which the termite-proofing agent 9 is arranged in the inner corner C as described above. For example, in the example shown in FIG. 12, the peripheral edge portion of the soil concrete 5 ′ covering the ground E in the lower floor portion extends to the inner surface 1 a of the outer periphery foundation 1, and the inner corner portion is formed by the soil concrete 5 ′ and the outer periphery foundation 1. C ′ is formed. And the termite-proofing agent 9 is arrange | positioned in this inner corner | angular part C ', and the heat insulating material 10 is attached above it. The soil concrete 5 ′ located below the heat insulating material 10 corresponds to the “lower member” according to the present invention.

  Furthermore, although not shown, the present invention can be applied to a so-called solid foundation in which no footing 2 is present. In this case, the outer periphery foundation which supports the building T is joined to the upper surface of the peripheral part of the bottom concrete (slab) cast in the ground E so that it may spread in a horizontal direction. Even in this case, as in the example of FIG. 12, the inner corner portion is formed by the outer peripheral foundation and the bottom base concrete, so that an anti-anticide can be applied to the inner corner portion.

  Furthermore, as shown in FIG. 13, the present invention is also applicable to the case where the heat insulating material 10 is attached above the ground E under the floor. That is, in the example of FIG. 13, the ant-proof sheet 7 is laid on the upper surface of the ground E, and the heat insulating material 10 is attached so that the peripheral edge of the ant-proof sheet 7 is sandwiched between the ground E. At the corner portion C ″ where the upper surface of the ground E and the inner side surface 1a of the outer peripheral foundation 1 intersect, an anti-anticide 9 is disposed, and a heat insulating material 10 is attached so as to cover the anti-ant agent 9 from above. In the example of FIG. 13, the portion of the ground E located below the heat insulating material 10 corresponds to the “lower member” according to the present invention.

FIG. 14 is a diagram for explaining the 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. 14, the heat insulating material 50 attached to the inner surface 1a of the outer periphery foundation 1 is divided into 2 in the height direction, and has the lower heat insulating material 50A and the upper heat insulating material 50B. ing. That is, the lower heat insulating material 50A is arranged so as to cover the upper surface of the footing 2 and a part of the inner side surface 1a of the outer peripheral foundation 1, and the upper heat insulating material 50B is further arranged on the upper surface of the lower heat insulating material 50A. The heat insulating material 50 (lower and upper heat insulating materials 50A and 50B) is disposed so as to cover almost the entire height of the inner side surface 1a of the outer peripheral foundation 1.

  At the inner corner portion C where the inner side surface 1a of the outer peripheral foundation 1 and the upper surface of the footing 2 intersect, an anti-anticide 9 is disposed.

  A bottom groove 52a in which the bottom surface 52 is partially cut out is formed at a corner of the bottom surface 52 of the lower heat insulating material 50A on the outer periphery foundation 1 side. The bottom groove 52a and an inner corner of the outer periphery foundation 1 are formed. The above-mentioned termite-proofing agent 9 is arranged so as to be accommodated in a space surrounded by C.

  The entire surface of the lower heat insulating material 50 </ b> A is covered with the nonwoven fabric 60. That is, 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. 14 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 addition, in FIG. 14, the nonwoven fabric 60 attached to each surface of 50 A of lower side heat insulating materials is represented by the thick continuous line. Moreover, although not clearly shown for convenience of illustration, in the second embodiment, the ant-proof sheet 7 is laid so as to extend to the outside (in the vicinity of the outer peripheral foundation 1) from the installation range of the soil concrete 5, and lower heat insulation The ant-proof sheet 7 also exists between the bottom surface 52 of the material 50 </ b> A and the top surface of the footing 2. The same applies to other embodiments (third to ninth embodiments) described later.

  The non-woven fabric 60 fulfills the function of guiding the maintenance ant repellent replenished during maintenance work to the position of the ant preventive agent 9 (in this case, the inner corner C), and corresponds to the “guide means” according to the present invention. To do. That is, in the maintenance work performed in order to maintain the ant-proof effect, as shown in FIG. 15, the portion of the nonwoven fabric 60 exposed under the floor, more specifically, the soil between the surfaces 53 of the lower heat insulating material 50A. For example, a spray-proofing device 70 is used to spray a maintenance termiticide 9 ′ on the non-woven fabric 60 located above the concrete 5.

  The maintenance insecticide 9 ′ sprayed from the sprayer 70 is impregnated into the exposed portion of the nonwoven fabric 60 and permeates the entire nonwoven fabric 60 over time. Thereby, the maintenance termiticide 9 ′ penetrates to the nonwoven fabric 60 located in the vicinity of the inner corner portion C of the outer periphery foundation 1, and finally reaches the termite inhibitor 9 arranged in the inner corner portion C. To do.

  As described above, in the second embodiment, the entire surface (the back surface 51, the bottom surface 52, the surface 53, the top surface) of the lower heat insulating material 50 </ b> A is used as a guide means for guiding the maintenance ant preventive 9 ′ to the inner corner portion C of the outer peripheral foundation 1. 54) Since the non-woven fabric 60 is provided to cover the non-woven fabric 60, the maintenance-use anti-protective agent 9 ′ is introduced into the inner corner C by a simple method of impregnating the non-woven fabric 60 with the maintenance anti-protective agent 9 ′. Can do. Further, since the non-woven fabric 60 is impregnated with the maintenance ant preventive agent 9 ′ during maintenance, the non-woven fabric 60 in the portion covering the back surface 51 and the top surface 54 of the lower heat insulating material 50 </ b> A particularly serves to prevent the invasion of white ants. In this sense, the ant-proof effect is improved.

  In particular, in the second embodiment, as the heat insulating material 50 attached to the inner side surface 1a of the outer peripheral foundation 1, a split type heat insulating material including the lower heat insulating material 50A and the upper heat insulating material 50B is adopted. It is sufficient to attach the non-woven fabric 60 only to the lower heat insulating material 50A (located above the termite-proofing agent 9), and it is not necessary to attach the non-woven 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 sprayer 70 (FIG. 15) is used for impregnating the nonwoven fabric 60 with the maintenance termite-proofing agent 9 ′. The non-woven fabric 60 may be impregnated with the agent 9 ′.

  By the way, when the exposed portion of the nonwoven fabric 60 is impregnated with the maintenance inhibitor 3 'by sprayer 70 or brush application, depending on the material of the nonwoven fabric 60 and the like, the maintenance inhibitor 9 can be applied up to the inner corner C of the outer periphery base 1. It is possible that 'does not penetrate sufficiently. Therefore, it is proposed to adopt a method as shown in FIG. 16 in order to more reliably infiltrate the maintenance ant preventive 9 'to the inner corner C.

  FIG. 16 shows an example in which a guide hole 61 is drilled in the heat insulating material 50 at the time of maintenance, and the maintenance termite-proofing agent 9 ′ is replenished using the guide hole 61. As shown in this figure, the guide hole 61 is, for example, drilled obliquely in the lower part of the upper heat insulating material 50B, and the corners (the upper surface 54 and the back surface 51 intersect each other on the outer peripheral foundation 1 side in the lower heat insulating material 50A. Open toward the corner. When replenishing the maintenance ant preventive agent 9 ′, the maintenance ant preventive agent 9 ′ is injected from the inlet of the guide hole 61 using an injector such as the syringe 20. The maintenance insecticide 9 'injected into the guide hole 61 is suddenly injected into the portion of the nonwoven fabric 60 that covers the back surface 51 of the lower heat insulating material 50A. Is expected to penetrate.

  In the case of providing the guide hole 61 and replenishing the maintenance termiticide 9 'as in the example of FIG. 16 described above, it is sufficient that the nonwoven fabric covers at least the back surface 51 and the bottom surface 52 of the lower heat insulating material 50A. At this time, the non-woven fabric is preferably attached so as to cover the entire back surface 51 of the lower heat insulating material 50A, but in the width direction including at least a portion into which the maintenance ant preventive 9 'is injected through the guide hole 61. You may make it provide a nonwoven fabric only in part.

  In the second embodiment, as in the first embodiment, the ant-proofing agent 9 is disposed at the inner corner C where the inner surface 1a of the outer periphery foundation 1 and the upper surface of the footing 2 intersect. As described in the embodiment, the disinfectant 9 is not limited to the inner corner C as described above. For example, as shown in FIG. 12, the termite-proofing agent 9 may be disposed at the inner corner C ′ of the outer peripheral foundation 1 and the soil concrete 5 ′, or the termite-proofing agent 9 at the inner corner (not shown) in the so-called solid foundation. Alternatively, as shown in FIG. 13, the termite-proofing agent 9 may be arranged at the inner corner C ″ of the outer peripheral foundation 1 and the ground E.

  In the second embodiment, as in the previous embodiment, the bottom groove 52a is formed on the bottom surface 52 of the lower heat insulating material 50A. However, by omitting the bottom groove 52a, the lower heat insulating material 50A is flat. You may use what has a simple bottom face. In this case, the termite-proofing agent is disposed so as to be stretched between the bottom surface of the lower heat insulating material 50A and the footing 2 or the like. In particular, in the second embodiment, when the bottom groove 52a of the lower heat insulating material 50A is omitted (when the bottom surface of the lower heat insulating material 50A is formed flat), the lower heat insulating material 50A has a rectangular cross section. Since it has a simple shape, post-processing is not necessary, which is advantageous in terms of cost.

  Moreover, in the said 2nd Embodiment, although the upper-and-lower bifurcated type heat insulating material 50 which has 50 A of lower side heat insulating materials and the upper side heat insulating material 50B was used, you may use the heat insulating material of an up-down integrated type.

And reaches the anti-anticide 9 disposed in the inner corner C through the nonwoven fabric 60.

  In the third embodiment as described above, as in the first and second embodiments, the place where the termite-proofing agent 9 is disposed is the inner corner portion C between the inner side surface 1a of the outer peripheral foundation 1 and the upper surface of the footing 2. However, the bottom groove 82a provided on the bottom surface 82 of the heat insulating material 80 may be omitted (for example, the inner corner C ′ or C ″ shown in FIGS. 12 and 13 may be used).

  In the third embodiment, the guide hole 85 provided in the heat insulating material 80 is not necessarily provided in advance when the heat insulating material 80 is applied. For example, it is of course possible to newly provide the guide hole 85 using a tool such as a hand drill during the maintenance for replenishing the maintenance termiticide 9 '.
