Description

  The present invention relates to a basic heat insulating structure having an ant-proof function in which an ant-proof function is added to a heat insulating material installed on a side surface of a foundation such as a house, and a construction method thereof.

  In recent years, as the heat insulation and airtightness of houses have progressed, the use of a basic heat insulation method in which a heat insulating material is applied to the side surface of the foundation has been actively used instead of a floor heat insulating method in which a heat insulating material is applied to the floor.

  Here, an example of a conventional basic heat insulating structure is shown in FIG. In this figure, a foundation 12 is placed on the ground 10. The foundation 12 has an inverted T-shaped cross-sectional shape in which the upright portion 12b rises from the center of the bottom portion 12a extending in the horizontal direction, and the bottom portion 12a and a part of the lower portion of the upright portion 12b are in the soil ( Buried in the ground 10). A base 30 of the house is installed on the upper side of the upright part 12b, and soil concrete 16 covering the ground 10 in the region is placed in the inner region of the foundation 12 (the right region in FIG. 8).

  And the heat insulating material 50 is arrange | positioned in the outer surface (left side surface in FIG. 8) of the said foundation 12 in the state embed | buried partially in soil. Further, a finishing wall 52 is constructed on the side opposite to the foundation side of the heat insulating material 50. In addition, although the example which applied the heat insulating material 50 only to the outer side surface of the foundation 12 was shown in this figure, the heat insulating material 50 can also be applied to the inner side surface (right side surface in FIG. 8) of the foundation 12 by the same structure. Is possible.

  Here, since the white ants which are pests have darkness as their range of action, if the heat insulating material 50 does not exist outside the foundation 12 in the first place, they climb up to the base 30 of the house through the outer surface of the foundation 12. Never come. However, when the heat insulating material 50 is disposed on the outer surface of the foundation 12 as shown in the figure, white ants in the soil reach the base 30 on the foundation 12 with the inside of the heat insulating material 50 as the ant road. There is a risk of intrusion. That is, the heat insulating material 50 is generally made of a foamed resin such as foamed polystyrene, foamed polyethylene, and foamed urethane, and these are materials that can be easily broken by white ants. If it is disposed on the outer surface of the foundation 12, white ants may break through the buried portion of the heat insulating material 50 and enter the inside, and there is a risk that an ant road 54, which is an entry path for white ants, may be formed. Arise.

For this reason, in patent document 1 below, the intrusion of white ants is performed by covering the side opposite to the foundation side of the heat insulating material 50 with an ant-proof sheet and constructing a finishing wall from the top.
Japanese Patent No. 3527654

  However, since the invention described in Patent Document 1 has a structure in which the entire side surface of the heat insulating material 50 on the side opposite to the foundation is covered with an ant-proof sheet, construction work at the site becomes large, and the ant-proof sheet is transported. There is a problem in terms of workability due to bulkiness during storage and storage, and there is also a problem that material costs increase.

  In addition, even if it does not use the ant-proof sheet | seat like the said patent document 1, if the underground burying part of the heat insulating material 50 is entirely covered with the finishing wall 52, it is possible to prevent an invasion of a white ant. Since the heat insulating material 50 is buried to some extent deep in the soil, it is not preferable in terms of work efficiency to cover the buried portion of the heat insulating material 50 with the finishing wall 52 even though it is for ant protection.

  This invention is made | formed in view of such a problem, and it aims at providing the basic heat insulation structure which has the ant-proof function which can be constructed efficiently at low cost, and its construction method.

As for solving the above problem, the first invention comprises a heat insulating material disposed on at least one of the outer surface and an inner surface of the foundation in a state of being partially embedded in the ground, the On the side opposite to the foundation side of the heat insulating material, a finishing wall is constructed over a predetermined height range straddling the ground surface. And a mounting surface on which the upper heat insulating material is placed on the top surface of the ant heat insulating material. And a recess-forming surface that forms a recess that is continuous from the mounting surface to the base-side side surface of the ant-proof heat insulating material and that is recessed from the mounting surface. In the space sandwiched between the lower surface of the material, the joint member with ant-proof function is placed in front. Joint member is the basis insulation structure which is filled in a state of closing the boundary between the dovetail insulation and foundation in contact with the side surface of the base (Claim 1).

According to this invention, a finishing wall is constructed over a predetermined height range straddling the ground surface on the side opposite to the foundation side of the heat insulating material disposed on the side surface of the foundation while being partially embedded in the soil. In addition, the heat insulating material is divided at a position higher than the lower end of the finishing wall, and the lower part of the divided surface is constituted by the ant-proof heat insulating material having a ant-proofing function. Of course, when the split surface of the material (the top surface of the ant-proof insulation) is set higher than the ground surface, the ant-proof effect is achieved even when the split surface is set lower than the ground surface. Obtainable. That is, when the dividing surface is set at a position lower than the ground surface, an upper heat insulating material made of a material (which can be eaten by white ants) such as foamed resin is partially embedded in the soil. However, even in such a case, the presence of the finishing wall that covers the buried portion of the upper heat insulating material in the soil can prevent the upper heat insulating material from being broken by white ants in the soil. In addition, if such a finishing wall is constructed so as to cover a certain range of the buried portion of the ant-proof heat insulating material, a portion of the ant-proof heat-insulating material against the white ants is covered by the finishing wall and the ant-proof heat insulating material. It is possible to obtain a heavy intrusion prevention effect.

Here, the anti-termite insulation material having a termite function, since in many cases more expensive than ordinary insulation material having no anti-termite function, the upper side of the anti-termite insulation is the termite insulation By disposing the upper heat insulating material, which is a separate member from the wood, only a part of the lower side of the heat insulating material arranged on the side surface of the foundation can be constituted by the ant-proof heat insulating material, and the foundation at a lower cost. An ant-proof function can be added to the heat insulation structure.

Also, be disposed entirely side of the foundation of the anti-termite insulation material in a state in which no gap between the anti-termite insulation and foundation, since it is generally difficult, the foundation and the anti-termite insulation material In the state where the gap between the two members is closed, the joint provided with the ant-proofing function is filled in the recess provided in the upper surface of the ant-proofing heat-insulating material in a state in contact with the side surface of the foundation. Thus , the joint member having an ant-proof function can close the gap between the ant-proof heat insulating material and the foundation, and the invasion of white ants trying to climb upward through the gap is prevented. Ant effect can be obtained.

In the first invention, when the concave portion as described above is provided in the ant-proof heat insulating material and the joint member is filled in the concave portion, the concave portion is formed by a tapered surface inclined downward toward the foundation side. (Claim 2).

  According to this configuration, the joint member filled in the concave portion is pressed against the outer surface of the foundation by its own weight along the tapered surface forming the concave portion of the ant-proof heat insulating material, and reliably contacts the surface. There is an advantage that intrusion is surely prevented.

In addition, according to a second aspect of the present invention, there is provided a heat insulating material constituted by an ant-proof heat insulating material having an ant-proof function and an upper heat insulating material disposed on the upper side of at least one of the outer side surface and the inner side surface of the foundation. A method for constructing a foundation heat insulating structure having an ant protection function, which is arranged in a state where it is partially embedded in soil, wherein the ant protection heat insulating material is arranged on a side surface of the foundation. Before the installation step and the ant-prevention heat insulating material disposing step, the shape of the upper surface of the ant-prevention heat insulating material is changed to the mounting surface on which the upper heat insulating material is placed and the foundation of the ant-proof heat insulating material from the mounting surface. An ant-proof heat insulating material forming step for forming a shape having a concave surface that forms a concave portion recessed from the mounting surface, the surface being connected to the side surface, and after the ant-proof heat insulating material disposing step, A joint part that fills a concave part of the ant heat insulating material with a joint member having an ant-proof function in contact with the side surface of the foundation. A filling step, and after the joint member filling step, an upper heat insulating material disposing step for disposing the upper heat insulating material on the upper side of the ant repellent heat insulating material; It is characterized by including a finishing wall construction step for constructing a finishing wall over a predetermined height range straddling the split surface of the ant-proofing insulation material and the upper insulation material and the ground surface on the side opposite to the foundation side of the insulation material. (Claim 3).

According to the construction method of the basic heat insulation structure having the ant proof function according to the second invention, it is possible to efficiently perform the large-scale construction that covers the entire outer surface of the heat insulating material with the ant proof sheet as in the prior art. An ant protection function can be added to the basic heat insulating structure.

  As described above, according to the basic heat insulating structure having the ant defense function and the construction method thereof according to the present invention, the ant proof function can be added to the basic heat insulating structure at low cost and efficiently.

  A preferred embodiment of the present invention will be described with reference to the drawings. In addition, in the following embodiment, except the part regarding an ant protection technique, it is the same as that of the structure shown in previous FIG. 8, The same referential mark is attached | subjected to the same element and the description is abbreviate | omitted.

(Embodiment 1)
FIG. 1 is a cross-sectional view showing a basic heat insulating structure having an ant protection function according to a first embodiment of the present invention. The heat insulating material 20 in this figure is divided into two by a divided surface 20a along the circumferential direction of the foundation 12 (direction perpendicular to the paper surface in FIG. 1), and an upper heat insulating material 21 above the divided surface 20a, It is comprised from the ant-proof heat insulating material 22 below the division surface 20a. Further, the height of the dividing surface 20 a is set at a position higher than the ground surface 10 a which is the surface of the ground 10.

  Among these, the upper heat insulating material 21 is comprised from foamed resin, such as a foamed polystyrene, a foamed polyethylene, a foamed urethane, similarly to the conventional heat insulating material 50 (FIG. 8).

  On the other hand, the ant-proof heat insulating material 22 is comprised with the heat insulating material which has an ant-proof function. For example, foam glass is suitable as the material for the ant-proof heat insulating material 22. Since glass is a hard material, it is not eaten by white ants and can exhibit its ant-proof effect alone. Further, the material of the ant-proof heat insulating material 22 does not have to exhibit the ant-proofing effect alone as described above. For example, a foamed resin (containing an ant-proofing agent) formed by kneading an ant-proofing agent is used. Foamed resin), or a foamed resin whose surface is treated by ant-proofing by applying an ant-proofing agent or immersing it in an ant-proofing chemical solution can also be suitably used. In addition, the kind of the ant protection agent used for these is not specifically limited, It is effective from various insecticides including a pyrethroid insecticide (silafluophene, etofenprox, bifenthrin, etc.) and an organic phosphorus insecticide. It is possible to select and use a proper one. Moreover, you may make it further improve an ant-proof effect by using what applied such an ant-proofing agent to the said foam glass.

  A finishing wall 28 made of mortar is constructed on the entire region of the side surface on the anti-foundation side of the upper heat insulating material 21 and part of the side surface on the non-foundation side of the anti-rust heat insulating material 22, and its lower end is lower than the ground surface 10a. Extends to position. Since the finishing wall 28 made of this mortar is normally constructed with almost no gap between the outer surface of the heat insulating material 20, white ants pass between the heat insulating material 20 and the finishing wall 28 and move upward. There is no such thing as a crawl. As the finishing wall 28, any material other than mortar can be used as long as it can be in close contact with the heat insulating material 20.

  Fig.2 (a) is the enlarged view of the said ant-proof heat insulating material 22 and its periphery. As shown in FIG. 2 (a) and FIG. 1 above, the corner on the base 12 side (the corner on the upper right side in the figure) in the upper surface of the ant-proof heat insulating material 22 is chamfered and formed thereby. The joint member 24 is filled in the recessed portion 22c. Specifically, as shown in FIG. 2B (a diagram showing a state in which the joint member 24 is schematically removed), the mounting surface on which the upper heat insulating material 21 is placed is placed on the upper surface of the ant-proof heat insulating material 22. 22a and a shape having a taper-shaped recess forming surface 22b that is formed from the mounting surface 22a to the base side surface of the ant-proof heat insulating material 22 and forms the recess 22c that is recessed from the mounting surface 22a. The joint member 24 is filled in a space sandwiched between the recess forming surface 22b and the lower surface of the upper heat insulating material 21.

  As shown in FIG. 2A, the joint member 24 is filled in a state of contacting the outer surface of the upright portion 12 b of the foundation 12. As a result, the gap A1 slightly generated between the outer surface of the foundation 12 and the foundation side surface of the ant-proof heat insulating material 22 is closed, so that the white ants are spaced between the foundation 12 and the ant-proof heat insulating material 22 (FIG. 2). Even if an attempt is made to enter upward through the gaps A 1, A 2) of (a), the entry is prevented by the joint member 24. Invasion of white ants from the gap can be more reliably prevented, for example, by laying an ant preventive agent on a portion of the upper surface of the base bottom 12a where the ant heat insulating material 22 is installed.

  The joint member 24 is made of a material having an ant-proof function. As the material of the joint member 24, for example, a glass particle material made of a large number of granular glasses is suitable. Since glass is hard as described above and is not eaten by white ants, it can exhibit an ant-proof effect alone. Of course, it is possible to use other than glass as long as the granular material has a hardness that does not eat by white ants. For example, a granular material made of calcium borate is also suitable. In addition, since the clearance gap between each granular material will become large and the penetration | invasion of a white ant cannot be stopped effectively if the particle size of these granular materials is too large, it is desirable that it is small to some extent. Further, the joint member 24 does not have to exhibit the ant-proof effect alone as described above. For example, resin pellets containing an ant-proof agent, a mixture of sand and an ant-proof agent, and an ant-proof agent are used. Urethane contained (aerosol type), other paste-like or grease-like substances mixed with an anti-bacterial agent, and the like can also be suitably used. In addition, you may make it further improve an ant-proof effect by using the thing which apply | coated the ant-proofing agent to the said granule of glass, the boric-acid borate, etc.

  Next, the construction method of the foundation heat insulation structure which has the above ant-proof functions is demonstrated.

  First, the ground 10 outside the foundation 12 is removed over a range necessary for the construction of the heat insulating material 20. At this time, as described above, the termite-proofing agent may be laid on the upper surface of the foundation bottom 12a.

  Next, the ant-proof heat insulating material 22 is disposed on the outer surface of the foundation 12. Before that, the top surface of the ant-proof heat insulating material 22 is placed with the mounting surface 22 a and the recess forming surface 22 b as described above. It shape | molds in the shape which has. And the said ant-proof heat insulating material 22 in which the said recessed part 22c was formed by the said shaping | molding is made along the outer surface of the foundation 12 in the attitude | position in which the recessed part 22c faces the upright part 12b side of the foundation 12, and the upper side. Arrange. At this time, if an adhesive is applied to the base side surface of the ant-proof heat insulating material 22, the ant-proof heat insulating material 22 can be stably fixed to the upright portion 12 b of the base 12. The adhesive need only be an amount that can fix the ant-proof heat insulating material 22 to a certain degree of stability, and it is not always necessary to apply the adhesive to the entire side surface of the base of the ant-proof heat insulating material 22.

  Next, the joint member 24 is placed in the recess 22c of the ant-proof heat insulating material 22 disposed on the outer surface of the foundation 12 as described above, and the placement surface 22a of the ant-proof heat insulating material 22 and the joint member 24 are flush with each other. Fill to the extent. The filling operation of the joint member 24 can be easily performed by spreading the joint member 24 in the recess 22c. In addition, when the granular material which consists of a glass particle material etc. is used as this joint member 24, you may make it apply | coat the hardening (adhesion) agent for hardening a granular material to the upper surface part. In this way, especially when the particle size of the granular material is small, it is possible to prevent the granular material from being scattered by the wind or the like.

  And the upper heat insulating material 21 is arrange | positioned above the ant-proof heat insulating material 22 with which the joint member 24 was filled in the recessed part 22c in this way (on the mounting surface 22a). Thereby, since the joint member 24 is covered with the upper heat insulating material 21, the filling state of the joint member 24 is thereafter stably maintained. In addition, in order to stably fix the upper heat insulating material 21 to the upright portion 12b of the foundation 12, an adhesive is applied to the side surface of the upper heat insulating material 21 on the base side in the same manner as when the ant-proof heat insulating material 22 is constructed. Good.

  Finally, a finishing wall 28 made of mortar is applied to the entire region on the side opposite to the base side of the upper heat insulating material 21 and part of the side surface on the side opposite to the anti-base side of the ant protection heat insulating material 22. At this time, the adhesion of the finishing wall 28 may be ensured by interposing a mesh-like lath (not shown) between the upper heat insulating material 21 and the ant-proof heat insulating material 22 and the finishing wall 28.

  According to the foundation heat insulating structure having the ant protection function according to the first embodiment of the present invention as described above, it is disposed on the outer surface of the foundation 12 in a state of being partially embedded in the soil (ground 10). The heat insulating material 20 is divided at a position higher than the ground surface 10a, and the ant-proof heat insulating material 22 below the dividing surface 20a is made of a material having an ant-proof function (that is, soil). Since all the parts embedded in it are made of the ant-proof heat insulating material 22 having the ant-proof function, the ant-proof heat insulating material 22 can be prevented from being eaten away by the white ants in the soil. It is possible to prevent the formation of ant roads penetrating the ant-proof heat insulating material 22 and the upper heat insulating material 21 thereon. Further, since the joint member 24 having an ant-proofing function is filled in the recess 22c formed on the upper surface of the ant-proof heat insulating material 22 so as to be in contact with the outer surface of the base 12, the base 12 and the ant-proof heat insulating material 22 are filled. The white ants that have crawled up through the slight gap between them (the gaps A1 and A2 in FIG. 2A) try to invade further above the upper surface (divided surface 20a) of the ant-prevention heat insulating material 22. Can also be prevented. Therefore, it is possible to prevent white ants from entering the base 30 on the foundation 12 without performing a large-scale construction that covers the entire side surface of the heat insulating material 20 on the side opposite to the foundation side with an ant-proof sheet. As a result, the ant-proof function can be added to the basic heat insulating structure at low cost and efficiently.

And since the finishing wall 28 extended to the position lower than the ground surface 10a is constructed in the anti-foundation side surface of the heat insulating material 20 as mentioned above, the underground burying part of the ant-proof heat insulating material 22 is partially finished wall. Therefore, in this area (area B shown in FIG. 2A), the double wall invasion preventing effect on the white ants can be obtained by the finishing wall 28 and the ant protection heat insulating material 22. .

In particular , as shown in FIG. 3, even if the dividing surface 20a is set at a position lower than the ground surface 10a, the finishing wall 28 is insulated at least over a range from a position lower than the dividing surface 20a to a position higher than the ground surface 10a. If construction is performed so as to cover the material 20 (that is, if the finishing wall 28 is constructed so as to straddle both the dividing surface 20a and the ground surface 10a), the entry of white ants can be prevented. That is, when the dividing surface 20a is set at a position lower than the ground surface 10a, the lower end portion of the upper heat insulating material 21 made of foamed resin that can be eaten by white ants is buried in the soil. However, even in that case, the presence of the finishing wall 28 covering the region (region C shown in FIG. 3) can prevent white ants in the soil from breaking through the upper heat insulating material 21.

In addition , as shown in FIG. 5, although it is also considered that it is an integral structure which consists only of the ant-proof heat insulating material 22 , if it does in this way, it will become disadvantageous in terms of cost. Conversely, for example, the heat insulating material 20 may be further finely divided by dividing the upper heat insulating material 21 and the ant-proof heat insulating material 22 into two.

  Further, in the first embodiment, the material of the upper heat insulating material 21 is made of the foamed resin as in the case of the conventional heat insulating material 50. However, the material is limited to the foamed resin as long as the heat insulating effect can be obtained. is not.

  In the first embodiment, the concave portion 22c of the ant-proof heat insulating material 22 is formed by the concave portion forming surface 22b composed of a tapered surface inclined downward toward the foundation 12 side. The shape of the concave portion 22c is a joint. The shape is not limited to this as long as the member 24 can be filled in a state where the member 24 can be brought into contact with the side surface of the foundation 12. For example, the concave portion 22 c may be formed by a concave portion forming surface (not shown) having an L shape in cross section. Good. However, when the concave portion 22c is formed by the tapered concave portion forming surface 22b, the joint member 24 is pressed against the outer surface of the foundation 12 by its own weight along the tapered surface constituting the concave portion forming surface 22b. This is advantageous in that the intrusion of white ants is reliably prevented. The same effect can be obtained when the recess 22c is formed by a recess forming surface (not shown) having an arc shape in cross section.

Further, the joint member 24 for preventing the invasion of white ants through the gap between the ant-prevention heat insulating material 22 and the foundation 12 (the gaps A1 and A2 in FIG. 2A) includes the gap A1 or A2. if it can be made application of anti-termite insulation material 22 in a state that does not occur at all it is thought be omitted. However, generally, it is difficult to dispose the ant-proof heat insulating material 22 so that the gap A1 or A2 is not generated at all . Therefore, it is necessary to fill the joint member 24 .

  Here, in Embodiment 1, when the circumferential length of the foundation 12 is somewhat large, FIG. 4 (the foundation heat insulating structure shown in FIG. 1 is cut in the horizontal direction along the dividing surface 20a, and the cut surface is an upper surface. As shown in the figure), it is sometimes necessary to construct the heat insulating material 20 in the circumferential direction across the joint surface 20c along the vertical direction (the direction perpendicular to the paper surface in FIG. 4). In such a case, since the white ants may crawl upward from the gap generated in the joint surface 20c, the corner portions of the joint portions of the ant-proof heat insulating material 22 are chamfered, and the joint portions as illustrated in the chamfered portions are illustrated. It is desirable to fill the joint member 24a. Similarly, the joint surface 20d formed at the corner of the foundation 12 is preferably jointed by the joint joint member 24b.

(Embodiment 2)
In the first embodiment, the heat insulating material 20 is disposed on the outer side surface of the foundation 12, but it may be disposed on the inner side surface of the foundation 12. FIG. 6 shows an example in which the heat insulating material 20 is arranged on the inner side surface of the foundation 12 as described above, and is a cross-sectional view of the basic heat insulating structure having an ant protection function according to the second embodiment of the present invention. . In addition, in this figure, although the example which has arrange | positioned the heat insulating material 20 only to the inner surface of the foundation 12 is shown, naturally the heat insulating material 20 can also be arrange | positioned to both the inner surface and the outer surface of the foundation 12.

  As shown in FIG. 6, in the second embodiment, the heat insulating material 20 including the upper heat insulating material 21 and the ant-proof heat insulating material 22 is disposed on the inner side surface (right side surface in FIG. 6) of the foundation 12. The dividing surface 20a between the upper heat insulating material 21 and the ant-proof heat insulating material 22 is set at a position higher than the ground surface 10a as in the first embodiment. Further, the concave portion 22c formed by chamfering the corner portion on the base 12 side (the corner portion on the upper left side in FIG. 6) of the upper surface portion of the ant-proof heat insulating material 22 is in contact with the inner surface of the base 12 The joint member 24 is filled. In the second embodiment, the installation location of the finishing wall 28 (FIG. 1 and the like) for covering the heat insulating material 20 is omitted because the place where the heat insulating material 20 is disposed is inside the foundation 12.

  According to such a configuration of the second embodiment, as in the first embodiment, an ant road that penetrates the ant-proof heat insulating material 22 and the upper heat-insulating material 21 is formed by the action of the ant-proof heat insulating material 22 and the joint member 24. In addition, it is possible to prevent white ants from entering through the gap between the ant-proof heat insulating material 22 and the foundation 12.

  However, in the second embodiment, the inner region (the right region in FIG. 6) of the foundation 12 on which the heat insulating material 20 is disposed is a region surrounded by the foundation 12 and the outer region (left region) of the foundation 12. Compared to the case of the first embodiment in which the heat insulating material 20 is disposed outside the foundation 12 when the heat insulating material 20 is disposed on the inside of the foundation 12 because it is darker than that, the darkness acts. The white ants in the range will be allowed to relatively easily enter the base 30 on the foundation 12 through the side opposite to the foundation of the heat insulating material 20. Therefore, in the second embodiment, by preventing white ants in the soil from coming out to the ground, invasion of white ants is surely prevented.

  Specifically, first, white ants appear on the ground surface over almost the entire inner region of the foundation 12 due to the presence of the soil concrete 16 placed on the ground 10 as in the conventional foundation thermal insulation structure (FIG. 8). It is to be prevented. That is, the soil concrete 16 also serves as an ant protection member that prevents white ants from appearing on the ground surface.

  However, even in this case, it is difficult to accurately perform the construction of the soil concrete 16 in a state in which no gap is generated between the peripheral end surface of the soil concrete 16 and the side surface opposite to the foundation side of the ant-proof heat insulating material 22. There is a possibility that white ants may enter through the gap inevitably generated (gap D1 shown in FIG. 6). Therefore, in the second embodiment, the digging portion 10b is formed in the ground 10 inside the foundation 12 in the portion adjacent to the ant protection heat insulating material 22, and the soil joint member 40 having the ant proof function is formed in the digging portion 10b. To be filled. Thus, the white ants are reliably prevented from entering through the gap D1 generated between the soil concrete 16 and the ant-proof heat insulating material 22.

  The material of the soil joint member 40 having an ant-proof function is not particularly limited as long as it has an ant-proof function and can be filled in the digging portion 10b. For example, the same as the joint member 24 It is possible to use the material (glass grain material etc.). Further, the cross-sectional shape of the digging portion 10b filled with the interstitial joint member 40 is not particularly limited, but in the second embodiment, the digging portion 10b is formed in the same manner as the concave portion 22c of the ant-proof heat insulating material 22. The surface to be formed is constituted by a tapered surface, so that the soil joint member 40 can reliably contact the ant-prevention heat insulating material 22.

  Moreover, in this Embodiment 2, although the soil concrete 16 was used as a thing (ant proof member) for preventing that a white ant comes out on the ground surface, if the same effect is acquired, things other than the soil concrete 16 will be used. Naturally, it is also possible to use it, and an example thereof is shown in FIG. In FIG. 7, an ant-proof sheet 17 having an ant-proof function is used as an ant-proof member that prevents white ants from appearing on the ground surface. The ant-proof sheet 17 is a flexible sheet made of a synthetic resin or the like, and is provided with an ant-proof function by kneading or applying an ant-proof agent to the sheet.

  In FIG. 7, the presence of the ant protection sheet 17 covering the ground 10 inside the foundation 12 over almost the entire area prevents white ants in the soil from coming out to the ground surface, and the digging portion 10b. Due to the presence of the soil joint member 40 that fills the digging portion 10b from the peripheral edge of the ant protection sheet 17 disposed on the tapered surface, the gap between the ant protection sheet 17 and the ant protection heat insulating material 22 is achieved. The white ants are prevented from entering upward through the gap D <b> 2 generated in FIG.
