Description

  The present invention relates to a flat-plate basic heat insulating material arranged on the building outdoor side of a building foundation start-up part, and a heat insulating basic structure for heat insulation on the building outdoor side of the building foundation using this basic heat insulating material.

  In recent years, it has been proposed to insulate a building even on a building foundation (for example, Patent Document 1).

JP 2005-23593 A

  In this patent document, a heat insulating material is arranged on the building exterior side of the building foundation, and the heat insulating material is covered with a decorative material, and the heat insulating material and the decorative material are made of stainless steel at the upper end side. It is fixed to the start-up part of the building foundation so as to be sandwiched with a restrainer.

  In the building foundation proposed in the above-mentioned patent document, the heat insulating material and the decorative material are sandwiched by the heat insulating suppressor with respect to the rising portion only on the upper end side. Therefore, if the holding by the pressing tool is insufficient, there may be a gap on the surface side of the rising portion. If this happens, the insulation and makeup material will be battered by the wind at the upper end as much as there is a gap, so there is a concern that inadvertent noise due to this fluttering and damage to the insulation material and decorative plate will occur Arrived.

  Moreover, the thickness of the start-up part of the building foundation varies depending on the scale and style of the building. Therefore, in order to sandwich and fix the heat insulating material and the decorative material to the rising part of the building foundation with various thicknesses with the above-mentioned heat insulating suppressor, it is necessary to prepare the heat insulating suppressor with various dimensions. It was complicated above.

  In view of the above-described problems, an object of the present invention is to ensure mounting on a rising portion and improve workability when mounting a heat insulating material on a rising portion of a building foundation.

  In order to achieve at least a part of the above object, the present invention adopts the following configuration.

[Application 1: Basic insulation]
It is a flat plate-like basic heat insulating material arranged on the building exterior side of the building foundation,
A heat insulating material body formed from a flat base material having heat insulating properties;
A fixing member formed from a material exhibiting hardness for fixing by a fixing metal fitting, and disposed at a predetermined pitch on the heat insulating material body,
The fixing member is
An internal member that remains inside the thermal insulation body;
Convex boss that is connected to the internal member and protrudes from one surface side of the heat insulating material body and is embedded in the raised portion made of concrete formed on the one surface side. The main point is to provide

  The flat base heat insulating material having the above-described configuration is disposed on the building outdoor side of the building foundation rising portion, and a heat insulating main body formed of a flat base material having heat insulating properties is joined to the rising portion. A fixing member made of a fixing metal, for example, a material exhibiting hardness for fixing with a nail or a screw, has already been disposed in the heat insulating body, and the fixing member is a member of the heat insulating body. A convex boss body connected to an internal member staying inside is protruded from one surface side of the heat insulating body.

  Since the start-up part of the building foundation is a foundation structure, it is usually made of concrete, and the foundation heat insulating material is disposed on the start-up part after curing the start-up part, that is, after hardening the concrete. It is not carried out for the building foundation and its start-up formwork. In other words, concrete is poured into a formwork that is built with the foundation insulation material, the concrete is cured inside the formwork, and the start-up part with the foundation insulation material placed on the outdoor side of the building together with the building foundation can get.

  In the formwork, the basic heat insulating material is in contact with the already placed concrete until after the concrete is cured. Therefore, during the curing, the concrete enters the voids of the foamed pores and the insulating fibers for heat insulation on one side of the heat insulation body included in the basic heat insulation material, and cures and cures in that state to become a startup part. The basic insulation is joined to the raised part. In this way, the concrete that has entered the one surface of the heat insulating material and has been cured and hardened functions to prevent the base heat insulating material from being peeled off from the rising portion, and to hold and fix the concrete.

  In the heat insulating material body of the basic heat insulating material, the convex boss body of the fixing member protrudes from one surface on the side where the concrete enters the foamed bubbles. Therefore, the concrete that has been driven into the formwork is cured and hardened in a state where the convex boss body is covered around the convex boss body, and the convex boss body is embedded in the concrete raised part. . Since this boss body is a part of a fixing member made of a material exhibiting hardness that is used for fixing by a fixing bracket such as a nail or a screw, the boss body is attached to a concrete start-up portion after curing and curing. The convex shape is maintained in the embedded state. In this way, the cured and hardened concrete covering the boss body that maintains the convex shape grips the boss body around the boss body. Serving function, holding and fixing function.

  As a result, the basic heat insulating material having the above-described configuration is securely bonded and attached to the rising portion obtained through the curing and curing of the concrete by the above-described peeling prevention function of the cured and concreted concrete. In addition, when mounting the basic heat insulating material having the above structure on the rising portion of the building foundation, it is not necessary to use an instrument that is sandwiched in the thickness direction of the rising portion, so that the rising portion can take various thickness dimensions. The workability of mounting on the is also increased.

  And when covering the foundation heat insulating material already attached to the rising part of the building foundation with a skin board such as a decorative board from the outside, nailing the fixing member of the base heat insulating material from the side of the skin board or Just screw it in. In this case, the fixing member is provided with a hardness that can be fixed by the fixing metal fitting, and is disposed at a predetermined pitch on the heat insulating body of the basic heat insulating material. Therefore, by nailing or screwing the fixing member according to this pitch, the skin board can be securely fixed to the basic heat insulating material, and the surface of the heat insulating material can be covered with the skin board.

  The basic heat insulating material described above can be in the following form. For example, the boss body can be formed into a protrusion shape that exhibits an anchor effect on the formed concrete raised portion, and an example thereof is a protrusion shape having inclined side surfaces. By doing so, the boss body functions to prevent the concrete that has been cured and hardened by covering the boss body, so that the effect of preventing the foundation heat insulating material from peeling off from the rising portion of the building foundation is further enhanced.

  In addition, the fixing members can be arranged in the heat insulating material main body in multiple rows at the pitch, and in this way, the boss bodies also become multi-rows, so that the boss bodies are peeled off by the cured and hardened concrete. A stop function etc. improve more and the effectiveness of the peeling prevention effect of a basic heat insulating material also becomes high. In addition, since the number of fixing points of the skin board when the base heat insulating material is covered with the skin board from the outside can be increased, the effectiveness of fixing the skin board to the basic heat insulating material is also increased.

  Further, the internal member of the fixing member may be flush with the heat insulating material main body on the surface opposite to the one surface through the heat insulating material main body. In this way, the skin board that covers the basic heat insulating material from the outside can be directly supported by the internal member of the fixing member, so the main body of the heat insulating material is inadvertently compressed when fixing the skin board such as nailing. You can avoid it.

[Application 2: Thermal insulation foundation structure]
A heat insulation foundation structure that insulates the building foundation on the outdoor side,
A part of the building foundation, at least the building outdoor side made of concrete;
The basic heat insulating material of any of the above-described embodiments;
A skin board arranged on the outer surface side of the basic heat insulating material,
The basic insulation is
The surface of the heat insulating material body on the side of the boss body that the fixing member has is joined to the concrete portion in the rising portion, and the boss body is embedded in the concrete in the rising portion,
The skin board is
The bottom of the building foundation extends from the upper surface of the abandoned concrete buried in the soil to cover the foundation heat insulating material, and is nailed from the board surface side to the internal member of the foundation heat insulating material and / or It is fixed to the basic insulation by screwing,
The skin board and the basic insulation are:
The gist is that it is buried in the soil on the side of the discarded concrete.

  Also by the heat insulation basic structure of the said structure, the certainty of installation of the basic heat insulating material with respect to a start-up part and workability increase. In addition, since the skin board can be a board having resistance against white ants, that is, having ant-proofing properties, the basic heat insulating material can be discarded and covered from the concrete upper surface with the ant-proofing skin board. Therefore, the effectiveness of suppressing the entry of white ants into the basic heat insulating material is enhanced.

  In the above-mentioned heat insulating basic structure, the top surface of the discarded concrete is provided such that the anticorrosive body bent in an L-shape is positioned on the lower end side of the skin board extending from the upper surface of the discarded concrete. And can be provided in close contact with the surface of the skin board. As such an ant-proof body, it is also possible to use a mesh body having multiple rows of pores that prevent entry of ants.

  When the basic heat insulating material is foamable, it is easily damaged by white ants, and the basic heat insulating material itself is likely to be an entry path for white ants. However, by arranging the ant-proof body bent in an L shape as described above, white ants can be prevented from entering from the lower end side of the skin board in the state of being embedded in the soil, and further, the damage caused by the white ants of the basic heat insulating material. Avoidance can be achieved. In this case, since the skin board itself has the above-mentioned ant-proofing property, the effectiveness of avoiding white ants entering and avoiding damage is further enhanced.

  Next, the form of this invention is demonstrated based on an Example. FIG. 1 is an explanatory view schematically showing a partially insulated base structure 10 according to an embodiment, and FIG. 2 is an explanatory view schematically showing the insulated base structure 10 in a state of being embedded in soil, FIG. 3 is an explanatory view showing a partially exploded view to show the pre-completion state of the heat insulating foundation structure 10.

  As shown in the figure, the heat insulating foundation structure 10 has a discarded concrete 12 as a lowermost layer, and the discarded concrete 12 is provided with a foundation concrete portion 20 which is a part of a building foundation of a building (not shown) and a rising portion extending upward. 30. This start-up part 30 is made of concrete formed through a process described later, and constitutes a building foundation together with the foundation concrete part 20. In addition, the heat insulation foundation structure 10 includes a flat foundation heat insulating material 40 and a skin board 50 on the outdoor side of the building up portion 30, and the lower end side of the skin board 50 is bent in an L shape. An ant mesh 60 is provided.

  The basic heat insulating material 40 includes a heat insulating material main body 42 and a fixing block 44. The heat insulating body 42 is a flat base material having heat insulation properties, such as plastic foam molded products such as hard urethane foam molded products, polystyrene foam molded products, polyolefin foam molded products, glass wool, rock wool, cellulose fiber and the like. It is a flat molded product of heat-insulating short fibers. The fixing block 44 is made of a material exhibiting hardness for fixing a skin board 50, which will be described later, for example, wood or plastic, and is disposed on the heat insulating body 42 at a predetermined pitch. In this embodiment, as shown in the figure, the fixing blocks 44 are provided in two rows in the vertical direction at a predetermined pitch.

  The fixing block 44 is integrally provided with an internal block 44a that remains inside the heat insulating material body 42 and an anchor block 44b. The anchor block 44b is a convex body that is connected to the inner block 44a and protrudes from the one surface side of the heat insulating material main body 42, and is embedded in the concrete rising portion 30 as shown in the figure. In this embodiment, the fixing block 44 is connected to the cylindrical inner block 44a by the truncated cone-shaped anchor block 44b having an inclined side surface. However, the inner block 44a is a prism and the anchor block 44b is a truncated pyramid shape. You can also

  In order to obtain the basic heat insulating material 40 provided with the fixing block 44 in the heat insulating material main body 42, when the heat insulating material main body 42 is a foam molded product, the fixing blocks 44 are arranged at a predetermined pitch in the mold, What is necessary is just to make a foaming agent foam. Further, even in the case of a flat plate molded product of heat insulating short fibers, the molding may be performed after the fixing blocks 44 are arranged at a predetermined pitch in the molding die. In addition, the fixing blocks 44 can be embedded and fixed at a predetermined pitch in the heat insulating material body 42 formed in a flat plate shape.

  The skin board 50 is a non-combustible board using plaster or the like, and can withstand resistance when buried in soil and avoid damage caused by white ants. The skin board 50 is arranged on the outer surface side of the basic heat insulating material 40 and joined to the heat insulating material, and is fixed to the fixing block 44 of the basic heat insulating material 40 by the nail N. At the time of nail fixing of the skin board 50, the skin board 50 is brought into contact with the upper surface of the discarded concrete 12 embedded in the soil and extends upward from the upper surface to cover the basic heat insulating material 40. Done.

  The ant-proof mesh 60 is a metal mesh steel plate rich in corrosion resistance, such as stainless steel, and is not allowed to allow white ants to enter and pass in the mesh size as well as the corrosion resistance of white ants. As shown in FIGS. 1 and 3, the ant-proof mesh 60 has an L-shape at a corner C formed by the lower end of the skin board 50 fixed to the basic heat insulating material 40 and the upper surface 12U of the discarded concrete 12. The bent corner is positioned and fixed. When fixing the ant-proof mesh 60, an adhesive is applied in advance to the upper surface 12U of the discarded concrete 12 and the lower-side surface of the skin board 50 including the corner C, and the ant-proof mesh 60 is pressed against the adhesive. Is called. That is, since the adhesive reaches the upper surface of the mesh while being hardened while filling the mesh of the ant-proof mesh 60, the ant-proof mesh 60 has a corner C on the upper surface 12U of the discarded concrete 12 and the lower surface of the skin board 50. It is adhered without any gaps. In this embodiment, the lower end of the skin board 50 is discarded and brought into contact with the upper surface 12U of the concrete 12.

  After the nail fixing of the skin board 50 and the placement / fixation of the ant-proof mesh 60, the heat insulating basic structure 10 having the above-described configuration is shown in FIG. It is buried so that the lower end side is in the soil. In the present embodiment, the heat insulating basic structure 10 is embedded in the ground line (GL) so that about 1/3 of the lower end side of the basic heat insulating material 40 is in the soil.

  Next, the manufacturing process of the heat insulation basic structure 10 is demonstrated. FIG. 4 is an explanatory view showing the relationship between the formation and curing of the foundation concrete portion 20 and the foundation heat insulating material 40, and FIG. 5 is an explanatory view showing the relationship between the cured foundation concrete portion 20 and the foundation heat insulating material 40. 6 is an explanatory view showing the relationship between the formation and curing of the start-up part 30 and the basic heat insulating material 40. FIG.

  As shown in FIG. 4, first, the discarded concrete 12 is formed and cured on the thrown stone S spread. After the curing, the building outdoor formwork 100 is discarded and installed on the upper surface 12U of the concrete 12. The outdoor outdoor formwork 100 has an outer vertical frame 102 so that the lower end of the outer vertical frame 102 contacts the upper surface 12U of the discarded concrete 12 with the outer vertical frame 102 fixed to the reinforcing frame members 104U and 104D at the upper and lower ends. 102 is erected. The upper and lower reinforcing frame members 104U and 104D are reinforced by the vertical reinforcing member 106 at appropriate intervals. In this case, the base heat insulating material 40 is disposed on one surface of the outer vertical frame 102 while ensuring a gap of several tens of millimeters between the lower end of the basic heat insulating material 40 and the upper surface 12U of the discarded concrete 12. The base heat insulating material 40 arranged in this way is held on the outer vertical frame 102 by the nail N driven from the outer vertical frame 102 side with respect to the fixing block 44 it has. In this case, the gap between the lower end of the basic heat insulating material 40 and the upper surface 12U of the discarded concrete 12 is made shorter than the length of the piece of the L-shaped ant mesh 60. That is, even when the gap is secured as described above, the lower end of the basic heat insulating material 40 is closed by the ant mesh 60.

  When the building outdoor formwork 100 is installed in this way, concrete is driven into a region indicated by a dotted line in FIG. As shown in FIG. 5, the poured concrete reaches the building outdoor formwork 100 side, and covers the surface (concrete contact surface 40 </ b> S) of the foundation heat insulating material 40 that is already held by the outer vertical frame 102. At this time, as shown in the drawing, the anchor block 44b of the fixing block 44 included in the basic heat insulating material 40 is covered with the cast concrete. Thereafter, the concrete is cured and hardened, and a foundation concrete portion 20 is formed as shown in FIG.

  During the curing of the concrete up to the formation of the foundation concrete portion 20, the poured concrete is a laminated void of foamed pores and insulation short fibers in the concrete contact surface 40 </ b> S of the insulation body 42 included in the foundation insulation 40 during the curing. It enters and cures and cures in that state. Thereby, the foundation heat insulating material 40 is joined to the end portion side of the foundation concrete portion 20 that forms a part of the concrete startup portion 30 after curing and curing. In addition, during the concrete curing, the concrete also enters into the foamed pores and the laminated voids of the heat insulating short fibers in the lower end side end surface 40D of the heat insulating material main body 42 of the basic heat insulating material 40, and is cured and cured in that state.

  Moreover, in the concrete in which the anchor block 44b protruding from the concrete contact surface 40S of the basic heat insulating material 40 is covered around the anchor block 44b, it is cured and cured while covering the anchor block 44b. In this case, since the fixing block 44 having the anchor block 44b is made of wood or plastic, it has a hardness that can be fixed by a fixing bracket such as a nail or a screw. The convex shape is maintained in a state of being embedded in the foundation concrete portion 20 forming a part of the raised portion 30. Therefore, the concrete that has been cured and hardened covering the anchor block 44b grips the anchor block 44b around the concrete.

  When the foundation concrete part 20 is formed through the concrete curing in this way, the building indoor side formwork 110 is formed as shown in FIG. 6 in order to form the rising part 30 on the end side of the foundation concrete part 20. It is installed on the upper surface of the discarded foundation concrete part 20 and is made to face the building outdoor side formwork 100. The indoor indoor formwork 110 has an inner vertical frame 112 so that the lower end of the inner vertical frame 112 is in contact with the upper surface of the foundation concrete portion 20 with the inner vertical frame 112 fixed to the reinforcing frame members 114U and 114D at the upper and lower ends. 112 is erected. The upper and lower reinforcing frame members 114U and 114D are reinforced by vertical reinforcing members (not shown) at appropriate intervals. In this case, between the outer vertical frame 102 of the formed outdoor outdoor formwork 100 and the inner vertical frame 112 of the indoor indoor formwork 110, the upper end side, that is, the upper end surface of the rising portion 30 to be formed. In the upper position, a spacing member 118 is appropriately disposed. Since the length of the spacing member 118 is adjusted in accordance with the thickness of the rising portion 30 to be formed, the outer vertical frame 102 and the inner vertical frame 112 are connected to the rising portion 30 to be formed. A region where the rising portion 30 is formed is formed to face each other with an interval corresponding to the thickness.

  When the building interior formwork 110 is thus installed, concrete is driven into the area indicated by the dotted line in FIG. The cast-in concrete is deposited in a region formed by the opposed outer vertical frame 102 and inner vertical frame 112 and covers the concrete contact surface 40S of the foundation heat insulating material 40 already held in the outer vertical frame 102. At this time, as shown in the drawing, the anchor block 44b of the fixing block 44 included in the basic heat insulating material 40 is covered with the cast concrete. Thereafter, the poured concrete is cured and hardened, and as shown in FIGS. 1 to 3, a rising portion 30 integrated with the concrete portion is formed on the end side of the foundation concrete portion 20. In the present embodiment, the upper end surface of the rising portion 30 is made to be the same height as the upper end surface of the basic heat insulating material 40, but the upper end surface of the rising portion is made to be several tens of millimeters higher than the upper end of the basic heat insulating material 40. You can also.

  During the concrete curing up to the formation of the start-up portion 30, the cast concrete is a laminated void of foamed pores and heat insulating short fibers in the concrete contact surface 40 </ b> S of the heat insulating body 42 included in the basic heat insulating material 40 during the curing. It enters and cures and cures in that state. Thereby, the basic heat insulating material 40 is joined to the concrete start-up portion 30 after curing and curing.

  Moreover, in the concrete in which the anchor block 44b protruding from the concrete contact surface 40S of the basic heat insulating material 40 is covered around the anchor block 44b, it is cured and cured while covering the anchor block 44b. In this case, since the fixing block 44 having the anchor block 44b is made of wood or plastic and has a hardness that can be fixed by a fixing metal fitting, it is embedded in the concrete start-up portion 30 after curing and curing. In this state, the convex shape is maintained. Therefore, the concrete that has been cured and hardened covering the anchor block 44b grips the anchor block 44b around the concrete.

  If the concrete of the start-up part 30 is cured and cured, the building outdoor side formwork 100 and the building indoor side formwork 110 are removed, and then the skin board 50 is covered so as to cover the foundation heat insulating material 40 as shown in FIG. After being bonded to the heat insulating material 40, the nail N is fixed to the fixing block 44 of the basic heat insulating material 40 with a nail N. This nailing is performed according to this pitch since the pitch of the fixing blocks 44 is a predetermined pitch as described above.

  Thereafter, an adhesive is applied to the lower end side surface of the skin board 50 that has been nail-fixed and the upper surface 12U of the discarded concrete 12 so as to include a corner portion C. 60 is pressed. When the mesh is pressed, an L-shaped bent corner is positioned at a corner C formed by the lower end of the skin board 50 and the upper surface 12U of the discarded concrete 12. Thereby, the ant-proof mesh 60 adheres to the lower end surface of the skin board 50 and the upper surface 12U of the discarded concrete 12 while closing the corner portion C with an L-shaped bent corner. The ant-proof mesh 60 is a mesh although it has pores that do not allow white ants to enter and pass through. As described above, the adhesive reaches the upper surface of the mesh while filling the mesh of the ant-proof mesh 60. The ant mesh 60 is discarded, and the upper surface 12U of the concrete 12 and the lower end side surface of the skin board 50 are bonded to each other including the corner portion C without gaps. In this case, since the ant mesh 60 is a fine pore through which the white ants cannot pass, it is not necessary for the ant mesh 60 to be tightly fixed by the adhesive throughout the longitudinal direction of the ant mesh 60. What is necessary is just to carry out at a regular interval. After the curing of the adhesive, as shown in FIG. Thus, the heat insulating basic structure 10 is completed.

  In the heat insulating foundation structure 10 of the present embodiment described above, when the foundation concrete portion 20 and the rising portion 30 at the end thereof are formed of concrete, the ground insulation 40 is placed between the concrete curing. The heat insulating material main body 42 has a concrete contact surface 40S as well as a foam void in the lower end side end surface 40D or a laminated void of heat insulating short fibers, and is cured and cured. As a result, the foundation concrete portion 20 and the rising portion 30 are cured and formed, and the foundation heat insulating material 40 is the end side of the foundation concrete portion 20 that forms the rising portion 30 made of concrete after curing and a part thereof. On the other hand, the concrete contact surface 40S and the lower end surface 40D are joined. Therefore, according to the heat insulation foundation structure 10 of the present embodiment, the foundation heat insulation to the start-up portion 30 and the foundation concrete portion 20 by the concrete that has entered the concrete contact surface 40S and the lower end side end surface 40D of the heat insulation body 42 and has been cured and hardened. The function of preventing the material 40 from peeling off and the function of holding and fixing are exhibited.

  Moreover, in the heat insulating basic structure 10 of the present embodiment, the anchor block 44b of the fixing block 44 provided on the heat insulating material body 42 is protruded from the concrete contact surface 40S, and then the cast concrete is anchored during the curing. Curing and curing is performed with the block 44b covered around the block 44b. Therefore, the anchor block 44b is embedded in the start-up portion 30 and the concrete foundation portion 20 made of cured and hardened concrete. Since the anchor block 44b is made of wood or plastic, which is the material of the fixing block 44, the anchor block 44b has a hardness that can be fixed by a fixing bracket. The convex shape is maintained while being embedded in the portion 20. For this reason, according to the heat insulation foundation structure 10 of the present embodiment, the anchor block 44b is gripped around the anchor block 44b by the hardened and hardened concrete. The function of preventing peeling, holding and fixing of the basic heat insulating material 40 to the concrete portion 20 is exhibited.

  For these reasons, the heat insulating foundation structure 10 of the present embodiment is obtained by using the above-described peeling prevention function of the hardened and hardened concrete, the foundation heat insulating material 40, and the start-up part 30 and the basic concrete part obtained through the hardening and hardening of the concrete. It becomes a building foundation that is securely bonded to 20. And when attaching the foundation heat insulating material 40 to the raising part 30 and the foundation concrete part 20 in a building foundation in this way, there is no restriction of the thickness of the raising part 30. As a result, according to the heat insulation basic structure 10 of a present Example, the workability | operativity in the case of mounting | wearing the foundation heat insulating material 40 with respect to the starting part 30 which can take various thickness dimensions can be improved.

  Moreover, in the heat insulation basic structure 10 of a present Example, when covering the base heat insulating material 40 with which it was mounted | worn as mentioned above with the skin board 50 from the building outdoor side, this skin board 50 is fundamentally insulated from the skin board surface side. The inner block 44a of the fixing block 44 of the member 40 is nailed or screwed. In this case, the fixing block 44 has a hardness for fixing by the fixing metal fittings, and is disposed at a predetermined pitch on the heat insulating body 42 of the basic heat insulating member 40. Therefore, the skin board 50 can be securely fixed to the basic heat insulating material 40 without any trouble by performing nail driving or screwing with the nail N on the inner block 44a of the fixing block 44 according to this pitch. As a result, according to the heat insulation foundation structure 10 of the present embodiment, the surface of the foundation heat insulating material 40 on the outdoor side of the building can be easily and reliably covered with the skin board 50, and the skin board 50 flutters as well as the foundation heat insulating material 40. Can be avoided.

  In addition, in the present embodiment, the anchor block 44b has a truncated cone shape having an inclined side surface, so that the anchor effect is exerted on the concrete start-up portion 30 and the foundation concrete portion 20 which are cured. For this reason, since it exhibits a high-efficiency retaining function with respect to the hardened and hardened concrete covering the anchor block 44b, the foundation heat insulating material 40 is prevented from peeling off the building foundation start-up portion 30 and the foundation concrete portion 20. The effect can be further enhanced.

  In addition, in this embodiment, since a plurality of fixing blocks 44 are received at a predetermined pitch in two upper and lower rows, the number of places where the anchor effect is exerted by the anchor block 44b also increases, so that the anchor block 44b is covered and cured. The anti-peeling function and the like by the concrete are further enhanced, and the effectiveness of the effect of preventing the peeling of the basic heat insulating material 40 is further improved. In addition, since the number of fixing blocks 44 is increased, the number of fixing points of the skin board 50 can be increased, so that the effectiveness of fixing the skin board to the basic heat insulating material 40 is enhanced.

  Furthermore, in this embodiment, the inner block 44a of the fixing block 44 is made to penetrate the heat insulating material body 42, and the top surface of the inner block 44a is flush with the other surface of the heat insulating material main body 42. Therefore, the skin board that covers the basic heat insulating material 40 from the outside can be directly supported by the top surface of the inner block 44a of the fixing block 44. Therefore, when fixing the skin board 50 by nailing or the like, the main body of the heat insulating material 42 can be prevented from being inadvertently compressed. That is, since the skin board 50 is not supported by the heat insulating material main body 42 such as a foam, the skin board 50 can be prevented from being swelled or dented due to nailing or the like, which is beneficial in terms of improving the appearance.

  In addition, in the heat insulating basic structure 10 of the present embodiment, the bottom end surface of the board and the discarded concrete are formed on the lower end side of the skin board 50 with an adhesive by using a stainless steel ant mesh 60 bent in an L shape. Twelve upper surfaces 12U were fixed tightly. At that time, the bent corner of the ant-proof mesh 60 is positioned on the lower end side of the skin board 50 that is in contact with the upper surface 12U of the discarded concrete 12 and extends upward, and is brought into close contact with the corner C. In this case, the upper surface 12U of the discarded concrete 12 and the lower end surface of the skin board 50 were brought into close contact with each other. For this reason, the ant mesh 60 fixed tightly as described above avoids the entry of white ants from the lower end side of the skin board 50 embedded in the soil, and further avoids the damage caused by the white ants of the basic heat insulating material 40. be able to.

  In addition, in this embodiment, the lower end surface of the skin board 50 is discarded and brought into contact with the upper surface 12U of the concrete 12, and the surface of the basic heat insulating material 40 (in detail, while the skin board 50 is directly supported by the fixing block 44) The heat insulating material main body 42 is in close contact with the surface). For this reason, the white ant approach to the base heat insulating material 40 can be avoided with high effectiveness in combination with the above-described arranged ant protection mesh 60.

  In this case, the skin board 50 is a non-combustible material and has a hardness that prevents white ants from eroding and can be made into a board material that is hard to break. Therefore, as long as no damage or cracking occurs due to an earthquake or the like, it is possible to prevent white ants from entering the base heat insulating material 40 with the skin board 50 itself.

  In general, since the skin board 50 is a standard material, the skin board 50 is spliced at a predetermined interval when placed on the rising portion 30 of the heat insulating basic structure 10. Therefore, in the present embodiment, the board joint portion is filled and coated with joint filler that exhibits hardness that does not cause the white ants to break after curing, and the joint between the board joint portions is filled with this joint filler. did. Therefore, white ants can be prevented from entering the base heat insulating material 40 also at the board joint portion of the skin board 50. That is, the skin board 50 itself, the joint filling process of the board joint portion, and the installation of the ant-proof mesh 60 on the corner C of the discarded concrete 12 and the skin board 50, the outer side of the rising part 30 is Since the ant-proof layer without a continuous gap can be formed in the surroundings, the entry of white ants from the outside to the basic heat insulating material 40 can be physically and effectively prevented by this ant-proof layer.

  As mentioned above, although the Example of this invention was described, this invention is not restricted to above-described embodiment, In the range which does not deviate from the summary, it is possible to implement in various aspects. For example, in this embodiment, the anchor block 44b has a truncated cone shape or a truncated pyramid shape. However, the anchor block 44b may have a columnar shape or a prism shape having the same shape as the inner block 44a. Further, when the fixing block 44 is formed of plastic, the anchor block 44b can be meshed. By so doing, the poured concrete enters the mesh-like anchor block 44b and is cured and hardened. Therefore, the concrete that covers and cures the anchor block 44b further enhances the peeling prevention effect.

  Moreover, although the ant-proof mesh 60 was installed in the lower end side of the skin board 50, it can also be set as the L-shaped bending plate which bent and formed the flat stainless steel sheet. In addition, in forming the heat insulating foundation structure 10, the foundation concrete portion 20 is formed first, and then the rising portion 30 is concrete-formed, but these can be formed almost simultaneously. In this case, after the building indoor-side formwork 110 is previously placed opposite to the building outdoor-side formwork 100 installed in the discarded concrete 12, an amount of concrete corresponding to the foundation concrete portion 20 is first driven. What is necessary is just to drive in an amount of concrete corresponding to the start-up part 30 in a so-called raw dry state at the initial stage of curing of the poured concrete.
