Description

  The present invention relates to a basic structure of a building such as a house. Moreover, it is related with the arrangement | positioning method of the ant-proofing agent in the basic structure of buildings, such as a house.

  Conventionally, the underfloor space surrounded by the foundation of the building and the first floor is maintained in a temperature environment and a humidity environment better than the outside environment. Colonies may be formed. On the other hand, it is conceivable that the medicine is sprayed in the underfloor space, but since the medicine may pass through even a slight gap, it may adversely affect residents living above the floor on the first floor. Absent.

  On the other hand, Patent Document 1 discloses a configuration in which an antproofing agent is disposed around the rise of the foundation and the joint between the soil concrete, and the antproofing agent is surrounded by a heat insulating material. Is prevented as much as possible in the space under the floor, and adverse effects on residents living above the first floor are avoided.

  In addition, as a method for extermination of white ants, conventionally, soil treatment and xylem treatment using chemicals in the field have been mainly performed. However, many of the chemicals used are harmful to the human body, and there is a problem in safety during processing.

  Therefore, recently, from the viewpoint of environmental measures, safety measures, and efficiency, wood factory processing, sheet method, bait method, etc. are becoming widespread. In particular, the bait method using a bait agent (poison bait) started in the United States, and began to be implemented 4 to 5 years ago in Japan. It is a safe and clean method, and has attracted attention as an efficient removal method.

  In this bait method, a container filled with food such as timber preferred by white ants is buried to attract white ants, and if it is found that white ants are eating this feeding tree, a part of the feeding tree is exchanged for poisonous food . This poison bait contains a slow-acting insecticidal component, but the non-toxic part of the base material is made by what white ants prefer, so the white ants will carry this bait little by little to the colony, and as a result The white ants in the colony are annihilated.

  When using this type of bait method for extermination of white ants, a station is embedded in the form of dots at intervals of 3 to 5 m on the ground outside the house, and the house is surrounded by any of the stations. A structure that remains as such an effect area (influence area) is known (see, for example, Patent Document 2).

JP 2005-213837 A JP 2003-137705 A

  However, in the configuration of Patent Document 1 described above, it is necessary to dispose the termite-proofing agent linearly along the rise of the foundation and the joints between the soil concrete, and there is a problem that the amount of the termite-proofing agent is excessive. It was. Especially in buildings that do not use timber as the main material, such as buildings with steel frames as structural bodies, white ants are relatively less damaged than wooden buildings. However, it is actually difficult to take a large-scale countermeasure such as that of Patent Document 1 only to prevent such minor damage.

  Also, in Patent Document 2, as in the case of Patent Document 1, in a building that does not employ wood as the main material of the structural frame or the outer wall, white ants have little damage, but a structure for preventing such damage. However, there is a problem that it is difficult to adopt from the viewpoint of labor and cost. Not only that, in the configuration of Patent Document 2, although the white ants can access the ant-proof station from a direction of 360 degrees, The station has an effective area only in an area of 180 degrees in a direction opposite to the building, and there is a problem that the capacity of each station cannot be fully utilized.

 In addition, there are heat insulating materials containing toxic components against white ants, but they are many times more expensive than ordinary heat insulating materials, and it is costly to place such expensive members so as to surround the outer periphery of the foundation. The effect is significantly reduced. Moreover, in a severe environment close to the outer boundary, there is a concern that the expiration date of the components may be remarkably reduced, and the construction method is also limited.

  The present invention has been made in order to solve such problems, and is effective in using as few ant-proofing agents as possible in buildings having a superstructure that does not use wood as the main material of the structural frame and outer wall. It aims at providing the basic structure which can exterminate white ants. Moreover, it aims at providing the arrangement | positioning method of the termite preventer which can exterminate a white ant effectively using as few as possible terminator.

(1) As a specific means for solving the above problems, the present invention is a basic structure that supports an upper structure in which at least the structural frame is made of steel or reinforced concrete and wood is used for all or part of the interior material and the base material. A continuous wall portion that supports the upper structure in a state in which part or all of the space below the upper structure is surrounded, and the underfloor space surrounded by the continuous wall portion has a predetermined distance from the continuous wall portion. It is characterized in that a solid termite-proofing agent is arranged at one or a plurality of positions separated by an interval.
According to this, the above-mentioned ant repellent permits the access of the white ants from any direction, whereby the white ants once entering the underfloor space reach the ant repellent from any direction. be able to. As a result, the area that exerts the effect of the ant protection by one ant protection agent can be expanded from the area of 180 degrees or less to the area of 180 degrees or more, and 360 degrees at the maximum in plan view. The amount used can be significantly reduced.

(2) Moreover, the said continuous wall part is equipped with the base frame part which supports the said upper structure, and the heat insulating material which is stretched by the inside or the outside of this base frame part, and surrounds the said underfloor space. It is preferable.
According to this, the temperature / humidity environment of the underfloor space can be brought closer to the indoor space above the floor portion than the outdoor space, thereby making the temperature gradient between the upper and lower floors of the first floor floor gentle, The cooling of the part can be suppressed. On the other hand, since the underfloor space is close to the indoor space, it becomes a suitable space for white ants, and there is a possibility that white ants gather more. However, by providing an anti-anticide in the space, white ants can be extinguished more reliably. .

(3) Moreover, it further comprises a foundation slab laid at least below the underfloor space, and the foundation frame part of the continuous wall part is predetermined from a support provided at a plurality of positions on the foundation slab and the upper surface of the foundation slab. It is preferable to provide a foundation beam constructed between adjacent columns in a state of being spaced apart.
According to this, since the entire under-floor space can be connected through the bottom of each foundation beam, there is no possibility that the effective area of the termite-proofing agent will be hindered by the foundation beam. A sufficient ant-proofing effect can be exhibited simply by installing an ant agent.

(4) Further, the Boarizai is preferably to the area 25 m ² no ² per one termiticide 100m is arranged in a plan view of the underfloor space. By disposing the termite-proofing agent in such a ratio, it is possible to obtain a sufficient extermination effect with the minimum termiticide.

(5) Moreover, it is preferable that the said foundation slab is provided in the position where the upper surface which supports the said support | pillar is higher than the ground of the outer periphery of the said building.
According to this, the possibility that rainwater from the outside flows on the foundation slab is prevented as much as possible, and it is possible to prevent performance deterioration due to the ant-proofing agent being immersed in rainwater.

(6) Furthermore, it is preferable to further provide a sub-anticide that reinforces the ant-proofing effect of the ant-proofing agent in the vicinity of the column.
According to this, a sub ant protection station is further provided in the vicinity of the column that can be said to be the only ant road that can be said to be the only ant road for moving from the outside to the superstructure, so that it is possible to more reliably prevent white ant damage to the superstructure. it can.

(7) Furthermore, as another specific means for solving the above-mentioned problem, the present invention is a method for arranging an anti-rust agent inside a foundation structure, wherein at least the structural frame is made of steel or reinforced concrete, and the interior material and the groundwork A base supporting a superstructure using wood for all or a part of the material, and the base includes a continuous wall portion supporting the superstructure in a state of surrounding a part or all of the space below the superstructure. And one or a plurality of solid termite-proofing agents are arranged in the underfloor space surrounded by the continuous wall portion and spaced apart from the continuous wall portion by a predetermined distance.
According to the arrangement method of the ant-repellent agent having the above-described configuration, it is possible to effectively remove the white ants using as little an ant-repellent agent as possible.

  ADVANTAGE OF THE INVENTION According to this invention, in the building which has the superstructure which does not use timber as a main body of a structural frame or an outer wall, a white ant can be exterminated effectively using as few ant preventives as possible.

 In the following, the basic structure and the arrangement method of the termite-proofing agent according to the present invention will be described in detail based on the embodiments. However, these embodiments are described in order to help understanding of the present invention, and Is not limited to the described embodiments.

The foundation structure A according to the present embodiment is a foundation structure having a foundation that supports an upper structure B in which at least a structural frame is made of steel or reinforced concrete and uses wood for all or part of the inner and outer materials and the base material.
And in the underfloor space C surrounded by the continuous wall portion of the foundation and the upper structure, a solid ant protection agent described later is disposed at one or a plurality of positions separated from the continuous foundation portion by a predetermined interval. It is a feature.
The above-mentioned termite-proofing agent placed in the underfloor space C allows the access of white ants from any direction, so that the white ants once entering the underfloor space are sought for food and then from any direction Even then, it can reach the ant-proofing agent. As a result, the area that exerts the effect of the ant protection by one ant protection agent can be expanded, and the amount of the ant protection agent used can be significantly reduced.

  Here, before describing the basic structure A according to the present embodiment, first, the upper structure B will be briefly described. The upper structure B includes a steel column erected on the foundation structure A, a steel beam spanned between the steel columns, a floor structure such as the first floor supported by the foundation structure A and the steel beam, and the foundation structure. An upper wall is supported by A and a steel beam, and the outer wall 1 which forms a room inside is comprised.

 As shown in FIG. 1, the outer wall 1 includes a plurality of flat paneled lightweight cellular concrete (ALC (Autoclaved Lightweight Aerated Concrete)) outer wall panels arranged side by side and supported by the foundation structure A through an angle 2. The heat insulating material and the interior member are laid in order (not shown) on the inner side (inside the room) of the outer wall panel.

 The first floor is formed by arranging a plurality of flat lightweight slabs 3 made of lightweight cellular concrete, and a floor finishing material is laid on the upper surface of the floor slab 3 through a self-leveling material. (Not shown). And the underfloor space C enclosed via the 1st floor part and the 1st floor room space D enclosed by the outer wall are formed. In addition, the heat insulation layer may be provided in the 1st floor part.

  Moreover, the hatch for accessing the underfloor space C may be provided in the 1st floor part. If it does in this way, the reduction | decrease of an ant inhibitor can be visually recognized and the penetration | invasion of a white ant can be recognized. Moreover, even when the effective period of the termite-proofing agent has passed, it can be easily replaced.

  The basic structure A according to the present embodiment includes a continuous wall portion 4 provided along the outer periphery of the upper structure and supporting the upper structure B while surrounding the underfloor space C below the first floor, and the continuous wall portion. 4 and a basic slab 5 positioned below the base 4.

The continuous wall part 4 is provided with the foundation housing | casing part 6 which is provided on the foundation slab 5, and supports the upper structure B, and the heat insulating material 7 stretched on the outer side of this foundation housing | casing part 6. As shown in FIG.
The foundation frame portion 6 is provided along a so-called outer street provided along the outer periphery of the building and supports the upper structure B, and the support columns 8 provided at a plurality of positions on the foundation slab 5 and the adjacent support columns 8. And a foundation beam 9 installed between them.
As shown in FIGS. 2 and 3, the foundation beam 9 is formed of H-shaped steel, and both ends thereof are fastened to the column 8 via the plate 10 with bolts or the like in a state of being separated from the foundation slab 4. In the present embodiment, a gap E having a height of at least about 5 cm is formed between the foundation slab 5 and the foundation beam 9 (FIG. 2).
The height of the gap E can be changed as appropriate. For example, if a height of about 40 cm is ensured, a person can move in the underfloor space C through the lower part of the foundation beam 9, and an anti-anticide described later. This makes it easy for people to access the ant and makes it easy to confirm these anti-anticides and to maintain other floors and foundations.

 The foundation slab 5 is made of reinforced concrete formed in a plate shape facing the entire bottom surface of the upper structure B, and the thickness is preferably 120 to 200 mm, for example, about 160 mm. As can be seen from FIG. 1, the upper surface of the outer peripheral portion of the foundation slab 5 is constructed so as to be higher than the ground surface GL of the outer periphery of the building. The outer peripheral ground surface is a ground surface around the foundation structure A that supports the upper structure B, and excludes the upper structure B and the ground immediately below the foundation structure A. Further, as shown in FIG. 1, the moisture-proof material 11 may be laid on the entire surface of the foundation slab 5.

  As shown in FIGS. 1 to 3, a concrete plate 12 such as a PC plate is embedded in a portion where the support column 8 is disposed on the upper surface of the foundation slab 5 over a region larger than the projected area of the support column 8. A steel raising member 13 is fixed on the concrete plate 12 by anchor bolts, and a steel column 8 is fastened on the raising member 13 by fastening means such as bolts.

  A plurality of concrete plates 12 are embedded in the longitudinal direction of the upper surface of the foundation slab 5 at positions corresponding to the positions where the foundation beams 9 are arranged. A plurality of supports 14 made of steel are fixed by anchor bolts, and a foundation beam 9 is placed on the support 11. In addition, although the installation space | interval of the support body 14 in the longitudinal direction of the foundation beam 9 is arbitrary, it is preferable to install at intervals of about 900-2000 mm, for example. The foundation beam 9 is placed on the support 14 and is not joined to the support 14.

In the above, the molten steel used in the normal underfloor space C is used as the steel material constituting the foundation frame 6 that forms the continuous rising part, that is, the support column 8, the foundation beam 9, the raising member 13, and the support body 14. Steel materials that have been subjected to rust prevention treatment such as plating can also be used, but in the structure of this embodiment, steel materials that have been subjected to the same simple rust prevention treatment as those used for the construction of the upper structure B are used. Is done.
In addition, the steel material which gave the rust prevention process only about the support | pillar 8 and the foundation beam 9 using the steel material by which the rust prevention process, such as hot dip galvanization, was given about either the raising member 13 and the support body 14 or both. It may be used. Moreover, even when all the basic frame parts 6 are formed of a steel material subjected to a simple rust prevention treatment, if deterioration of the members is observed after living for a certain period, only the raising member 13 and / or the support body 14 are used. It can also be exchanged.

Moreover, the heat insulating material 7 which comprises the said continuous wall part 4 is stretched along the outer periphery of the foundation housing part 6 in this embodiment, The outer peripheral surface is slightly under floor space C rather than the outer wall of an upper structure. Set to the position set back to the side.
By being stretched at such a position, the heat insulating material 7 is in a state of surrounding not only the underfloor space C but also the foundation housing 6 and the foundation slab 5. Further, the heat insulating material 7 is provided so as to be immersed to the same extent as the lower surface of the foundation slab 5, and is independent along the foundation beam 9. As a result, the side surface of the concrete foundation slab 5 having a heat transfer coefficient higher than that of the ground is protected by the heat insulating material 7, and a heat flow path is formed around the side surface of the foundation slab 5. The path becomes longer for heat insulation.
Further, it is preferable that the heat insulating material 7 is not brought into contact with the foundation beam 9 or is brought into partial contact even if it is brought into contact. This is to increase the heat insulation effect by reducing the heat transport path.

 The heat insulating material 7 is laminated | stacked by the outside air direction from the underfloor space C, and is installed by the multiple layer (in the example of illustration, 2 layers). This is to prevent the outside air from entering the underfloor space C through the joints by shifting the joints in each layer.

Moreover, in this embodiment, the heat insulating material 7 uses the foamed plastic heat insulation board about 20 mm thick from a viewpoint of versatility and heat insulation performance. As this type of heat insulating plate, XPS (extruded polystyrene foam) is preferable. XPS has a low thermal conductivity of 0.028 to 0.040 W / mK, so it can be expected to have a high heat insulation effect, and there is no permeation of water as a liquid, and a moisture permeability specific resistance against permeation as a gas (water vapor). It is as large as 400 to 600 mhmmHg / g. It is also a material that does not deteriorate due to moisture. Therefore, it is optimal as the heat insulating heat insulating material 7 to be immersed in the soil.
In addition, as the heat insulating material 7, any material may be used as long as it is a plate-shaped material having desired air permeability and heat insulating properties and sufficient water resistance and water stopping properties. Therefore, it is possible to use inorganic fiber materials other than woody materials and organic resin materials other than those described above.

 Moreover, the sealing material 15 is filled between the upper end of the heat insulating material 7 and the outer wall 1, thereby preventing the inflow of outside air into the underfloor space C more reliably.

 Further, a protective coating layer 16 is formed on the outer surface of the heat insulating material 7 on the surface exposed to the outside air mainly for preventing ultraviolet deterioration. The protective coating layer 16 is generally formed by thin coating of mortar, but a double coating material made of polymer cement mortar and enamel top coating material can also be applied. In addition, when it is desired to impart surface strength to the heat insulating material 7, a metal mesh can be provided between the layers when the heat insulating material 7 has an outer surface, an inner surface, or multiple layers.

 In the construction of the foundation structure A having the above-described configuration, first, after performing root cutting work in accordance with the foundation structure A, reinforcement is performed for forming the foundation slab 5, and the heat insulating material 7 is installed before and after that. . Next, concrete is cast to form the foundation slab 5. At this time, the heat insulating material 7 installed prior to the concrete casting also functions as a formwork. After the foundation slab 5 is formed, backfilling is performed, and the foundation frame portion 6 such as the foundation beam 9 is constructed to complete the foundation structure A.

 And the ant-proofing agent 17 is arrange | positioned in the 1 or several position on the foundation | slab slab 5 (or moisture-proof material 11) away from the foundation housing part 6 by predetermined spacing. According to the foundation structure A according to the present embodiment, the anti-anticide 17 is disposed in the underfloor space C surrounded by the foundation slab 5, the heat insulating material 7, the first floor, etc., and thus is exposed to the environment such as rainwater. Therefore, the effect of the drug can be maintained for a long time.

 After installation of the termite-proofing agent 17, the upper structure B is then assembled. The protective coating of the heat insulating material 7 is performed before and after backfilling. In addition, when the hatch etc. are provided in the 1st floor part, you may install the anti-anticide 17 after the upper structure B is assembled.

 Moreover, the timing of concrete placement can be shifted after the construction of the foundation frame 6. That is, in another method, when the root cutting work and bar arrangement are performed in accordance with the foundation structure A, the foundation frame portion 6 is constructed. Next, after the heat insulating material 7 is installed, concrete is cast to construct the basic structure A, and then the upper structure B is assembled. According to such a process, since the positional relationship between the foundation frame portion 6 and the heat insulating material 7 is determined before placing concrete, high finishing accuracy of the heat insulating material 7 can be ensured.

According to the basic structure A having the above configuration, since the outside air is prevented from being blown into the inside by the heat insulating material 7, the deterioration of the termite-proofing agent 17 disposed in the underfloor space C is suppressed. Also,
The base frame 6 is prevented from being contacted with the ground below the base slab 5, and the heat insulating material 7 is also prevented from being contacted with the outside air or rainwater blown by the outside air. Since it is located above the ground surface GL, contact with the ground is prevented, and contact with rainwater that accumulates on the ground to the extent that the water level does not reach the upper surface of the foundation slab 5 is also prevented. Therefore, since contact with moisture contained in these is suppressed as much as possible, the rust prevention treatment of the basic casing portion 6 is sufficient with the treatment substantially similar to the steel material of the upper structure B, and such normal prevention Even when a steel material subjected to rust treatment is used as a basis, rust and the like can be prevented over a long period of time, whereby high durability can be maintained over a long period of time.

 Moreover, since the heat insulation layer will be formed in the outer periphery of the basic | foundation housing | casing part 6 which supports the upper structure B by using the heat insulating material 7 which is excellent in heat insulation performances, such as XPS, conventionally, the upper structure B of the upper structure B is used. The heat insulation layer provided under the first floor, which is the bottom surface, can be omitted, and the underfloor space C is opposed to the first floor room through only the first floor without using the heat insulating material. The state can be brought closer to the first floor room.

  Next, the termite-proofing agent 17 arrange | positioned in the underfloor space C of the foundation structure A demonstrated above is demonstrated.

  As described above, since the basic structure A of the present embodiment has a better thermal environment than the outside, even if the upper structure A has few xylems that serve as food, the white ants provide the heat insulating material 7. It may be possible to break into the underfloor space C by eating it. For example, if the upper structure A is a wooden building, the white ants entering the underfloor space C may move from the underfloor space C to the support column 8 to the upper structure A through the foundation or the like. In the basic structure A according to the present embodiment, since no wood is present in the underfloor space C, the white ants that have entered the underfloor space C seek and eat the bait without leaving the underfloor space C. It arrives at the sex ant-proofing agent 17.

  The termite-proofing agent 17 is preferably a solid, and is a slow-acting insecticidal (having a killing effect after a few days or weeks), and is not particularly limited. What impregnated or apply | coated the solution prepared using non etc. to solid materials, such as cloth, a fiber, and paper, is used.

 The white ants eat the ant control agent 17 to inoculate the poison, and die several days or weeks later. In addition, when another white ant eats a solid carcass that has died due to the inoculation of the poisonous substance, the white ant is killed in units of colonies. In the basic structure according to the present embodiment, there is no wood or the like that serves as white ants in the underfloor space C other than the termite-proofing agent 17, so that poisons are reliably given to the white ants that have entered the underfloor space C. be able to.

Further, instead of directly placing the solid medicine on the basic slab 5, a device called an ant-proof station 18 that can contain the ant-proofing agent 17 may be installed inside the underfloor space C. In the basic structure according to the present embodiment, since the white ants can access the anti-anticide 17 from all directions, the ant-proof station 18 preferably has a shape that allows the white ants to enter from all directions.
For example, as shown in FIG. 4, the ant-proof station 18 has a structure having a bottom for installing the ant-proofing agent 17, a pillar extending upward from the bottom, and a roof supported by the pillar. Those are preferred. The ant protection station 18 having such a shape can draw out the effective range of the ant protection agent 17 to the maximum extent. Moreover, by using the ant-proof station 18, contact with the basic slab 4 can be prevented, deterioration of the ant-proof agent 17 due to moisture or the like can be suppressed, and the installation of the ant-proof agent 17 is facilitated.

Further, as shown in FIG. 5, as the installation position or installation method of the termite-proofing agent 17, the termite-proofing agent 17 is arranged at a predetermined interval away from the foundation frame portion 6 surrounding the foundation slab 5.
In addition, it is preferable that only one anti-anticide 17 is disposed per area 25 to 100 m ² of the basic slab 5. By disposing the termite-proofing agent 17 at such a ratio, it is possible to obtain a sufficient extermination effect with the minimum termite-proofing agent 17. That is, if the area of the basic slab 5 is within the above range, only one anti-anticide 17 may be disposed as shown in FIG. Alternatively, when the area of the foundation slab 5 exceeds 100 m ² , a plurality of the termite-proofing agents 17 may be arranged at predetermined intervals as shown in FIG. Further, when the area of the foundation slab 5 is smaller than 25 m ² , it is sufficient to dispose one ant protection agent 17.

 In addition, since the white ants that have entered the underfloor space C may reach the upper structure B from the support column 8 or the foundation beam 9 of the fabric foundation, the sub-ant protection station in which the sub-anticide is accommodated in the vicinity of the support column 8. May be provided. In particular, by disposing a solid chemical or sub-ant protection station in the vicinity of the support column 8, it is possible to prevent intrusion into the upper structure and damage to floor materials and wooden household items caused by white ants. The sub ant protection station has the same configuration as the ant protection station 18.

 According to the present invention, in a non-wooden building whose structural frame is made of steel or concrete, or in a building where wood is locally used, white ants are effectively removed using as little ant protection as possible. As a result, the cost can be significantly reduced as compared with the conventional method for dealing with white ants, and the effect is also long-term. Accordingly, it is possible to achieve a remarkable effect that is not possible in the past, which can significantly reduce the discomfort of the resident for a long period of time.

 Moreover, since the foundation structure A of this embodiment is a structure installed in the state in which the foundation beam 9 was spaced apart from the foundation slab 5, if the underfloor space C is surrounded by the continuous street wall 4 of the outer street, the foundation will be in the middle street. Even when the beam 9 is provided, the entire underfloor space C communicates with each other without being blocked by the foundation beam 9, so that the underfloor space C is regarded as one space and the anti-anticide 17 It is only necessary to provide several anti-anticides 17 in the underfloor space C, which is very efficient. In addition, since the underfloor space C communicates with each other in this way, the white ants that have entered the underfloor space C can access the ant-preventing agent 17 from any direction. In other words, the effective area of the termite-proofing agent 17 can be exerted over 360 degrees, which makes it possible to arrange the termite-proofing agent 17 efficiently.

 As mentioned above, although especially preferable embodiment of this invention was described, this invention is not limited to this embodiment, It is possible to implement in various deformation | transformation aspects.

 For example, even a basic structure based on a normal reinforced concrete cloth foundation has the same effects as the present invention. In such a configuration, as shown in FIG. 6, it is considered that the underfloor space is divided into a plurality of spaces by the cloth foundation formed in the middle street of the building. One enclosed space that is surrounded is an underfloor space C, and an anti-anticide 17 is disposed for each underfloor space C. The number of arrangements is based on the area of each section of the divided basic slab 5.

 Further, when the above-mentioned section is not a section in contact with the outside, that is, a section surrounded only by the foundation beam of the fabric foundation, it is considered that white ants do not enter. There is no particular need to arrange. Also, when only a part of the lower space of the upper structure B is surrounded by the basic structure A, it is possible to dispose the termite-proofing agent 17 with the enclosed section as the underfloor space C.

In addition, it is possible to adopt a configuration in which the heat insulating material 7 is provided indoors with respect to the foundation beam 9, and also in a case where a configuration in which the heat insulating material 7 is provided on the inside and outside of the foundation beam 9 is also used in the present invention. The same effect is produced.
