It is a perspective view of the boundary part heat insulating body of FIG. It is sectional drawing of the structure which is the ant-proof heat insulation underfloor structure which concerns on other embodiment of this invention, and has a slope in which a boundary part heat insulating body faces diagonally upward. FIG. 6 is a cross-sectional view of a structure in which a slit is formed inside a boundary heat insulator, which is a structure for preventing ant heat insulation according to still another embodiment of the present invention.

  FIG. 1 shows a schematic diagram of a structure in the present embodiment. In this figure, the foundation 100 is installed in the ground E, and the building T is installed on it.

  In the illustrated example, the foundation 100 is a fabric foundation including a footing 101 and an upright portion 102 disposed on the footing 101, and is an under-floor portion of the building T (the right side portion of the foundation 100 in this figure). The same applies to FIG. 2 and subsequent figures.) Is installed on the ground E so as to surround.

  On the surface of the ground E corresponding to the underfloor portion, that is, on the upper surface of the interstices 110, the interstitial concrete 120 is disposed so as to cover substantially the entire surface of the underfloor portion, and the end surface of the interstitial concrete 120 is the inner side surface 102a ( This corresponds to the inner side surface of the foundation, hereinafter referred to as the inner side surface 102a of the foundation 100).

  Moreover, in this embodiment, the ant-proof sheet | seat 150 in which the ant-proof material contained in base materials, such as polyethylene, is interposing between the soil concrete 120 and the ground E. An end 150 a of the ant-proof sheet 150 extends into the gap 140 between the foundation 100 and the soil concrete 120.

  The “inside” described below in the description of the present embodiment means the floor underside (in FIG. 1, the direction toward the right with respect to the foundation 100).

  Furthermore, the heat insulation part 130 is arrange | positioned so that the area | region from the part located above the upper surface of the soil concrete 120 among the inner side surfaces 102a of a foundation to the upper surface of the soil concrete 120 may be covered.

  The heat insulating portion 130 includes a foundation-side heat insulating panel 131, a dirt-side heat insulating panel 132, and a boundary heat insulating body 135.

  The foundation-side heat insulation panel 131 corresponds to the foundation-side heat insulating material of the present invention, and is fixed to the inner side surface 102a of the foundation 100. Specifically, the foundation-side heat insulation panel 131 is spaced from the boundary portion 141 between the inner surface 102a of the foundation 100 and the upper surface 120a of the soil concrete 120 by a first interval S1 (see FIG. 2), and the inner surface 102a of the foundation 100. Coating. The base-side heat insulation panel 131 is made of a material that hardly penetrates the chemical solution and has high heat insulation properties, such as extruded polystyrene (XPS).

  The dirt-side heat insulation panel 132 corresponds to the dirt-side heat insulating material of the present invention, and covers the upper surface 120a of the dirt concrete 120 with a second interval S2 (see FIG. 2) from the boundary portion 141. Similarly to the base-side heat insulation panel 131, the soil-side heat insulation panel 132 is made of a material that hardly penetrates the chemical solution and has high heat insulation properties, such as extruded polystyrene (XPS).

  As shown in FIG. 1, the dirt-side heat insulation panel 132 of this embodiment is divided into a plurality of parts, for example, a first part 132a and a second part 132b. The first portion 132a is detachably provided on the upper surface of the soil concrete 120. The second portion 132b is fixed to the upper surface of the soil concrete 120. Thus, since a part of the dirt-side heat insulation panel 132 can be removed from the dirt-concrete 120, it is possible to easily repair or check the crack of the dirt-concrete 120.

  The boundary heat insulator 135 corresponds to the chemical solution distribution member of the present invention, and as shown in FIG. 2, within the range of the first interval S1 along the inner surface 102a of the foundation 100 from the boundary portion 141, And it arrange | positions so that the range of 2nd space | interval S2 along the upper surface 120a of the soil concrete 120 may be plugged up from the said boundary part 141. FIG. The boundary heat insulator 135 is made of a fibrous material that can be penetrated by the chemical solution for ant protection, and is made of at least one of glass wool and rock wool in this embodiment.

The density of the glass wool used for the boundary heat insulator 135 is preferably 10 to 32 kg / m ³ so that both the permeability of the chemical solution and the heat insulating performance can be maintained. When the density exceeds 32 kg / m ³ , the permeability of the chemical solution is significantly reduced. When the density is less than 10 kg / m ³ , the heat insulation performance is reduced (that is, the thermal conductivity is increased), so the density of glass wool Is within the above range, it is preferable because both the permeability of the chemical solution and the heat insulation performance can be maintained to a practically satisfactory level. More preferably, the glass wool used for the boundary heat insulator 135 is required to have sufficient strength to be used for heat insulation of the foundation 100, and therefore it is preferable to use glass wool having a density of 32 kg / m ³ or slightly lower than that. .

When rock wool is used as the boundary heat insulator 135, the density of the rock wool is preferably 10 to 50 kg / m ³ so that both the permeability of the chemical solution and the heat insulation performance can be maintained. When the density exceeds 50 kg / m ³ , the permeability of the chemical solution is significantly reduced. When the density is less than 10 kg / m ³ , the heat insulation performance is reduced (that is, the thermal conductivity is increased). If the density is within the above range, it is preferable because both the permeability of the chemical solution and the heat insulation performance can be maintained to a practically satisfactory level. More preferably, since the rock wool used for the boundary heat insulator 135 is required to have sufficient strength to be used for heat insulation of the foundation 100, the rock wool having a density of 50 kg / m ³ or slightly less than that is used. Is preferred.

  In the present embodiment, the first interval S1 is set to be larger than the thickness D2 of the dirt-side heat insulating panel 132. Moreover, 2nd space | interval S2 is set so that it may become larger than thickness D1 of the foundation | substrate side heat insulation panel 131. FIG. Therefore, the boundary heat insulator 135 disposed so as to close the range of the first space S1 and the second space S2 is greater than the thickness D1 of the foundation-side heat insulation panel 131 and the thickness D2 of the dirt-side heat insulation panel 132. Since it has a large dimension, it is possible to ensure heat insulation performance. At the same time, it is possible to secure the inner corner 135a (see FIG. 2) of the boundary heat insulator 135 as a spraying location for the ant-proofing agent. The vertical surface 135b and the horizontal surface 135c of the inner corner portion 135a are exposed to the under floor side (under the floor space U).

  As shown in FIG. 3, the boundary heat insulator 135 of the present embodiment is formed of a rod-shaped body having a rectangular cross section made of at least one of glass wool and rock wool. The dimensions of the boundary heat insulator 135 are not particularly limited in the present invention. For example, the width X of the boundary heat insulator 135 is about the thickness D1 + 10 mm of the foundation-side heat insulating panel 131, and the height H is between the soils. The side heat insulation panel 132 is set to have a thickness D2 + 20 mm and a length L of about 910 mm or 1820 mm. At least a part, preferably all, of the fibers constituting the boundary heat insulator 135 are arranged so as to face substantially in the horizontal direction.

  The boundary heat insulator 135 is impregnated with an anti-ant chemical. As will be described later, the chemical solution for ant proof is applied to the boundary heat insulator 135 from a place away from the boundary heat insulator 135 by spraying or spraying with a spray or injection with a long dispenser. The

  As the chemical solution for ant protection, for example, a mixture of an ant control chemical and a resin binder is used.

  Examples of the anti-anticides include pyrethroid-like drugs (silafluophene, etofenprox, etc.), pyrethroid drugs (bifenthrin, cypermestone, deltamethrin, permethrin, permethrin, allethrin, tralomethrin, etc.), carbament drugs (provoxl, fenocarb, sebin, etc.) , Chlornicotyl drugs (imidacloprid, acetapride, clothianisin, etc.), Nitroganillin drugs (dinotefuran, etc.), Organophosphorus insecticides (Hoxime, Tetraclocupinphos, Fenitrothion, Probetanphos, etc.), Pyrazole drugs (Fibronyl, etc.), Chlorphenol Drugs (4-promo-2,5-dichlorophenol (BDCP), etc.), phenylpyrroles (chlorfenavir, etc.), Hiba oil, turmeric, capric acid Coconut oil, palm oil, and the like.

  The resin binder is a latex type in which a petroleum rubber adhesive, a surfactant and an anti-anticide are mixed in a synthetic rubber emulsion, and an aqueous emulsion type in which water, a thickener and an anti-anticide are mixed in a synthetic rubber emulsion. Liquid-curing elastic polyurethane adhesives, oil types in which thickeners and ant-proofing agents are mixed in lubricating oil, and asphalt-based liquid materials in which bitumen emulsions are mixed with ant-proofing agents are used.

  In addition, the viscosity of the ant-preventive chemical solution is preferably low in consideration of the ease of injection and penetration of the chemical solution, and specifically, the viscosity is 30 mPa · s or less (preferably 10 mPa · s or less). Is preferred.

(Construction method for under-floor insulation floor structure)
Below, the construction method of the ant-proof heat insulation structure of this embodiment is demonstrated.

  First, as a stage before disposing the boundary heat insulator 135, as shown in FIGS. 1-2, the first interval S1 from the boundary portion 141 between the inner surface 102a of the foundation 100 and the upper surface 120a of the soil concrete 120 is shown. (See FIG. 2), the foundation-side heat insulation panel 131 is attached to the inner side surface 102a of the foundation 100. Next, a caulking agent 136 for preventing ants is applied to the boundary portion 141.

  Next, a second interval along the upper surface 120a of the soil concrete 120 within the range of the first interval S1 along the inner surface 102a of the foundation 100 from the boundary portion 141 after the caulking agent is cured. Within the range of S2, the boundary heat insulator 135 is disposed on the boundary portion 141. In addition, when installing the boundary part heat insulator 135 newly, you may install the boundary part heat insulator 135 in the state impregnated with the chemical | medical solution for ant proofs beforehand.

  Thereafter, the dirt-side heat insulation panel 132 is attached to the upper surface 120a of the dirt concrete 120 with a second interval S2 (see FIG. 2) from the boundary portion 141. Specifically, as shown in FIG. 1, the second portion 132 b of the dirt-side heat insulation panel 132 is attached to the upper surface 120 a of the dirt concrete 120 at a position away from the boundary heat insulator 135, and then removable second. The first portion 132a is fitted between the second portion 132b and the second portion 132b. At this time, the fitting operation may be performed while finely adjusting the length of the first portion 132a so that the first portion 132a fits tightly between the second portion 132b and the second portion 132b.

  As described above, the construction of the ant-proof heat insulation floor structure subjected to the ant-proof treatment is completed.

(Anti-proof method)
Next, the ant-proof heat insulating underfloor structure constructed as described above was impregnated in the ant-proof caulking agent 136 or the boundary heat insulator 135 after a long period of time (for example, about 5 to 10 years) after the construction. When the medicinal effect of the ant-preventive chemical solution is lowered, the boundary portion 141 is filled with the ant-preventive chemical solution by the following ant-proof method.

  Specifically, first, as described above, the boundary heat insulator 135 is disposed in advance in the boundary portion 141 so that a part of the boundary heat insulator 135 is exposed to the lower floor side (boundary portion). Insulator arrangement process).

  In that state, the operator inserts a spray nozzle into the underfloor space U, and places the chemical solution N for ant protection away from the boundary heat insulator 135 as shown in FIG. 2 toward the boundary heat insulator 135. Spray or spray from (ant-prevention chemical application step). At this time, the chemical solution N applied to the boundary heat insulator 135 from a remote location can penetrate the inside of the boundary heat insulator 135 and reach the boundary portion 141. This makes it possible to easily and reliably apply the chemical solution to the boundary portion 141 even in a place where the floor is narrow.

  Further, when the chemical liquid N is injected into the boundary heat insulator 135, the dirt-side heat insulation panel 132 adjacent to the boundary heat insulator 135 functions to block the chemical liquid N inside the boundary heat insulator 135. Therefore, it can prevent that the chemical | medical solution N flows into the position away from the boundary part 141 along the upper surface 120a of the soil concrete 120. FIG.

  In addition, the application of the chemical solution for ant-proofing may be performed not only by spraying or spraying by spraying but also injecting into the boundary heat insulator 135 by a long dispenser or the like.
