Description

The present invention relates to a basic insulation and adiabatic substructure.

  In recent years, there has been proposed a method for avoiding the invasion of white ants into the basic heat insulating material after the building is insulated in the building foundation (for example, Patent Document 1). In this white ant avoidance technique, a heat-insulating flat plate base material in the foundation heat insulating material is embedded in the rising portion in advance, and a skin board separate from this flat plate base material is embedded in the soil at the lower end of the building foundation. It extends from the upper surface of the discarded concrete and is attached later to a flat base material, and the intrusion of white ants is avoided by an L-shaped bent ant body on the lower end side of the skin board.

FIG. 1 is an explanatory view schematically showing a partially insulated base structure 10 as an embodiment of the present invention, and FIG. 2 is a schematic sectional view showing the insulated base structure 10 embedded in soil. It is explanatory drawing.

  As shown in the figure, the heat insulating foundation structure 10 includes a foundation concrete portion 20 on the discarded concrete 12 with the discarded concrete 12 as a lowermost layer. The foundation concrete part 20 is made of concrete so as to include a rising part 30 through a process described later, and constitutes a building foundation of a building (not shown). The heat insulating foundation structure 10 includes a flat foundation heat insulating material 40, a first ant-proof mesh 60H extending in the horizontal direction at the lower end of the basic heat insulating material 40, and an adjacent basic heat insulating material on the building outdoor side of the foundation concrete portion 20. 40V, and a second ant-proof mesh 60V extending in the vertical direction.

  The basic heat insulating material 40 has a rectangular shape with predetermined vertical and horizontal dimensions, and a plurality of basic heat insulating materials 40 are prepared for each divided region obtained by vertically dividing the basic concrete portion 20. Each basic heat insulating material 40 includes a heat insulating material main body 42 and a skin board 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. In addition, a block that performs an anchoring function may be embedded in the heat insulating material main body 42 so that the anchor portion protrudes from the back surface of the heat insulating material main body 42.

  The skin board 44 is a nonflammable board using plaster or the like, and can withstand resistance when buried in the soil and avoid damage caused by white ants. The skin board 44 has the same vertical and horizontal dimensions as the heat insulating body 42 and is attached to the heat insulating body 42 in advance with an adhesive or the like. In the heat insulating foundation structure 10, the foundation heat insulating material 40 is arranged in the foundation concrete portion 20 side by side in the horizontal direction, and the skin board 44 is positioned on the outdoor side of the building so as to be flush with the outer surface of the rising portion 30. Further, the foundation heat insulating material 40 is embedded in the soil together with the foundation concrete portion 20 on the side of the discarded concrete 12 in a state in which the heat insulation main body 42 included therein is embedded in the foundation concrete portion 20 and the rising portion 30 thereof. .

  The first ant-proof mesh 60H and the second ant-proof mesh 60V are metal mesh steel plates rich in corrosion resistance, such as stainless steel, and are not allowed to allow white ants to enter and pass in the mesh size as well as resistance to white ants. Yes. The first ant mesh 60H rises from the upper surface 12U of the discarded concrete 12 and covers the lower end side of the skin board 44 together with the outer surface of the foundation concrete portion 20 as shown in FIG. 1 and FIG. And the heat insulating material main body 42 are in close contact with each other. The second ant mesh 60V extends from the upper end to the lower end of the basic heat insulating material 40 between the adjacent basic heat insulating materials 40 arranged in the horizontal direction, and the surface of the skin board 44 of the adjacent basic heat insulating material 40. Close contact with. Since the second ant-proof mesh 60V and the first ant-proof mesh 60H overlap at the lower end side of the second ant-proof mesh 60V, in the present embodiment, as shown in FIG. It covers the ant-proof mesh 60V. On the contrary, the second ant protection mesh 60V may be put on the first ant protection mesh 60H. Both the first and second ant meshes can be fixed when the foundation concrete portion 20 and the rising portion 30 are cured as described later, and the skin board of the base heat insulating material 40 adjacent to the lower surface of the skin board 44. Alternatively, an adhesive may be applied to the surface of 44, and both ant meshes may be pressed against the adhesive and fixed. In fixing with the adhesive, the adhesive reaches the upper surface of the mesh while filling the meshes of the first and second ant-proof meshes, so that both the first and second ant-proof meshes are used for the skin board. On the surface of the skin board 44 of the basic heat insulating material 40 adjacent to the lower end side surface of 44, it adheres without a gap. In this case, it is not necessary for the adhesive to fill all the pores of the two ant-proof meshes, and the pores that remain unfilled exhibit ant-proof properties due to their size.

  In the heat insulating basic structure 10 having the above-described configuration, the first heat insulating mesh 60H and the second heatproof mesh 60V are disposed and fixed, and the basic heat insulating material 40 is disposed on the outdoor side of the building as shown in FIG. The ant mesh 60H and the second ant proof mesh 60V are buried in the soil in a range including the lower end side. 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. 3 is an explanatory diagram showing the relationship between the formation and curing of the foundation concrete portion 20 and the foundation heat insulating material 40, and FIG. 4 is an explanatory diagram showing the relationship between the cured foundation concrete portion 20 and the foundation heat insulating material 40. 5 is an explanatory diagram showing the relationship between the state of formation / curing of the start-up unit 30 and the basic heat insulating material 40.

  As shown in FIG. 3, 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, on one surface of the outer vertical frame 102, a space of several tens mm is secured between the lower end of the basic heat insulating material 40 and the upper surface 12U of the discarded concrete 12, and the basic heat insulating material 40 is arranged in the horizontal direction. Arranged. Prior to or along with this heat insulating material arrangement, the first ant mesh 60H and the second ant mesh 60V are set on the outer vertical frame 102. That is, in the first ant mesh 60H, it extends along the lower end side surface of the outer vertical frame 102 in the horizontal direction while being in close contact with the lower end side surface of the outer vertical frame 102 extending from the upper surface 12U of the discarded concrete 12. The arrangement is set. In the second ant-proof mesh 60V, the long side dimension of the basic heat insulating material 40 is used as a pitch, and extends along the outer vertical frame 102 almost vertically from the upper end side to the lower end side of the outer vertical frame 102. The arrangement is set. The first ant-proof mesh 60H, the second ant-proof mesh 60V, and the basic heat insulating material 40 thus arranged are held on the outer vertical frame 102 by the nail N driven from the outer vertical frame 102 side. . In this case, an adhesive is used in the contact area between the first ant mesh 60H and the base heat insulating material 40 and the contact area between the second ant mesh 60V and the basic heat insulating material 40, and the basic ant mesh is previously used as the basic heat insulating material. More specifically, it is desirable to adhere to the surface of the skin board 44 in detail. Further, 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 width of the first ant-proof mesh 60H. That is, even when the gap is ensured as described above, the skin board 44 of the basic heat insulating material 40 is blocked by the first ant-proof mesh 60H on the lower end side.

  When the building outdoor formwork 100 is thus installed, concrete is driven into the area indicated by the dotted line in FIG. As shown in FIG. 4, the cast-in concrete extends to the building outdoor formwork 100 side, and covers the surface (concrete contact surface 40 </ b> S) of the foundation heat insulating material 40 held in the outer vertical frame 102. Thereafter, the concrete is cured and hardened, and a foundation concrete portion 20 is formed as shown in FIG. By this concrete curing, the base heat insulating material 40 is embedded in the base concrete portion 20 on the lower end side of the base heat insulating material 40 and fixed to the base concrete portion 20 by this embedding. In addition, if the block which makes an anchor action is embed | buried under the foundation heat insulating material 40, fixation of the foundation heat insulating material 40 to the foundation concrete part 20 will become strong.

  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 joins with the edge part side of the foundation concrete part 20 containing the start-up part 30 made from the concrete after 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. In addition, since concrete enters the pores of the first ant-proof mesh 60H exposed on the lower end side of the foundation heat insulating material 40 and is cured and hardened, the first ant-proof mesh 60H is securely fixed to the foundation concrete part 20. . In this case, it is not necessary for the concrete to fill all the pores of the first ant-proof mesh 60H, and the pores that remain unfilled exhibit ant-proof properties due to their size.

  When the foundation concrete part 20 is formed through the concrete curing in this way, as shown in FIG. 5, a building indoor side formwork 110 is formed to form a rising part 30 on the end side of the foundation concrete part 20. It installs on the upper surface of the foundation concrete part 20, and is made to oppose the building outdoor side formwork 100. FIG. 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 indoor formwork 110 is thus installed, concrete is poured 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. Thereafter, the poured concrete is cured and hardened, and as shown in FIGS. 1 to 2, 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. 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 as shown in FIG. Thus, the heat insulation foundation structure 10 is completed, and in the heat insulation foundation structure 10 in a completed state, the foundation concrete portion 20 has a stepped portion 20S extending to the upper end of the rising portion 30 on the outdoor side of the building. The heat insulating body 42 of the basic heat insulating material 40 is abutted against the portion 20S, and the skin board 44 is positioned on the outdoor side of the building.

  By the way, when arrange | positioning after the formation and curing of the heat insulation basic | foundation structure 10 shown in FIGS. 3-5 in the 1st termite mesh 60H and the 2nd termite mesh 60H, the 1st termite mesh 60H is as follows. And fix the second ant mesh 60V. Regarding the first ant mesh 60H, the lower end side surface of the skin board 44 of the foundation heat insulating material 40 that is abutted and fixed to the stepped portion 20S of the foundation concrete portion 20 and aligned in the horizontal direction, and the foundation concrete portion below it After the adhesive is applied to the outer surface of 20, the first ant mesh 60H is pressed against the applied adhesive. In the second ant-proof mesh 60V, an adhesive is applied to the surface of the heat insulating body 42 between the adjacent basic heat-insulating materials 40, and the second ant-proof mesh 60V is applied to the applied adhesive. Press. The first ant mesh 60H and the second ant mesh 60V are meshes although they have fine pores that do not allow white ants to enter and pass through. As described above, the adhesive is used for both ant meshes. While filling the mesh, it reaches the top of the mesh and hardens. As a result, the first ant mesh 60H is tightly fixed to the outer surface of the rising portion 30 and the surface of the heat insulating body 42 so as to cover the lower end side of the skin board 44 together with the outer surface of the rising portion 30. The second ant mesh 60V extends from the upper end to the lower end of the basic heat insulating material 40 between the adjacent basic heat insulating materials 40 arranged in the horizontal direction, and the surface of the skin board 44 of the adjacent basic heat insulating material 40. It is closely fixed to. In addition, since the 1st ant-proof mesh 60H is elongate, and the mesh itself is made into the pore which a white ant cannot pass through, the close fixation of the 1st ant-proof mesh 60H with an adhesive is the 1st ant-proof mesh. The mesh 60H need not be applied in the entire longitudinal direction, and may be performed at an appropriate interval. After the curing of the adhesive, as shown in FIG. Thus, the heat insulating basic structure 10 is completed.

  In the heat insulation foundation structure 10 of this embodiment demonstrated above, when forming the foundation concrete part 20 and the standup | rising part 30 of the edge part with concrete, between concrete curing, the foundation concrete is made into the foundation insulation 40. 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 the foundation heat insulating material 40 is a stepped portion on the end side of the foundation concrete portion 20 including the rising portion 30 made of concrete after curing. The concrete contact surface 40S and the lower end side end surface 40D are joined to 20S. 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.

  For this reason, the heat insulating foundation structure 10 of the present embodiment has the foundation heat insulating material 40 obtained from the curing and hardening of the concrete by the above-described peeling prevention function of the hardened and hardened concrete and the foundation concrete part. 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.

  In the heat insulation foundation structure 10 of this embodiment, the heat insulation of the building foundation is achieved by arranging a plurality of foundation heat insulating materials 40 side by side on the foundation concrete portion 20 in the horizontal direction. Since each of the basic heat insulating materials 40 has already been equipped with the skin board 44 on the outer surface of the heat insulating main body 42 having heat insulation properties, retrofitting of the skin board 44 in the field work becomes unnecessary. Therefore, according to the heat insulating basic structure 10 of the present embodiment, it is possible to reduce work man-hours and work man-hours, and to reduce costs. Further, in the heat insulating foundation structure 10 of the present embodiment, in order to prevent ant-proofing of the heat insulating material body 42 in the basic heat insulating material 40, the first ant-proof mesh 60H is used, and the lower end side of the skin board 44 is connected to the foundation concrete portion 20 and The second ant-preventive mesh is also provided between the adjacent basic heat insulating materials 40 arranged in the horizontal direction after being closely fixed to the outer surface of the rising portion 30 and the surface of the skin board 44 so as to cover the outer surface of the rising portion 30. 60V may be tightly fixed to the surface of the skin board 44, and the bent deformation of the ant-proof body is not required. Therefore, according to the heat insulation basic structure 10 of this embodiment, installation of both said ant-proof meshes becomes easy, and the reduction of the man-hour and cost reduction can be aimed at.

  In the heat insulation basic structure 10 of this embodiment, even if a white ant enters the side of the basic heat insulating material 40 along a shallow portion in the soil or the ground, the second between the adjacent basic heat insulating materials 40 arranged in the horizontal direction. The ant mesh 60V prevents the white ants from reaching between the adjacent basic heat insulating materials 40. Further, even if the white ants are thrown away from the outer surface of the concrete 12 and enter the side of the basic heat insulating material 40 along the outer surface of the raised portion 30, the first ant ants that cover the lower end side of the skin board 44 together with the outer surface of the raised portion 30. The mesh 60H can prevent the white ants from reaching the basic heat insulating material 40 from the lower end of the skin board 44. As a result, according to the heat insulating basic structure 10 of the present embodiment, it is possible to further improve the ant protection.

  In the heat insulation foundation structure 10 of the present embodiment, the foundation heat insulating material 40 is embedded in the stepped portion 20S of the foundation concrete portion 20 so that the skin board 44 is substantially flush with the outer surface of the foundation concrete portion 20. Therefore, the operation | work at the time of making the 1st termite mesh 60H closely_contact | adhere to the outer surface of the foundation concrete part 20 and the surface of the skin board 44 becomes easy so that the lower end side of the skin board 44 may be covered with the outer surface of the foundation concrete part 20. In particular, when the first ant-proof mesh 60H and the second ant-proof mesh 60V are disposed after the formation and curing of the heat insulating foundation structure 10 shown in FIGS. When substantially flush, the bonding work of both ant-preventive meshes is easy and desirable.

  Next, another embodiment will be described. FIG. 6 is an explanatory view schematically showing a partially insulated base structure 10A according to another embodiment. In this embodiment, with the first ant mesh 60H and the second ant mesh 60V already installed, both ant meshes, including the outer surface of the skin board 44, are coated with mortar MC with 鏝 KT. Extend and finish the exterior. According to 10A of this embodiment, the appearance can be improved, and the adhesion of both ant-preventive meshes to the surface of the skin board 44 is enhanced and the adhesion is ensured, so that the ant-repellency is more reliably secured. Can demonstrate. In this case, mortar coating such as spraying may be used instead of mortar coating with 鏝.

  The present invention is not limited to the above-described embodiment, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features of the embodiments corresponding to the technical features in each embodiment described in the summary section of the invention are intended to solve part or all of the above-described problems, or part of the above-described effects. Or, in order to achieve the whole, it is possible to replace or combine as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.

  In the present embodiment, 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. In addition, the first ant mesh 60H and the second ant mesh 60V are overlapped with each other, but the second ant mesh 60V can be extended to the upper end of the first ant mesh 60H.

  In this embodiment, the first ant mesh 60H and the second ant mesh 60V are metal mesh steel plates rich in corrosion resistance such as stainless steel, but a thin leaf-like stainless steel plate having a thickness of 1 mm or less, stainless steel, etc. A sliver obtained by forming a metal having a high corrosion resistance into a fine line shape may be woven into a non-woven fabric. Further, a coating agent in which small diameter single fibers of stainless steel or the like rich in corrosion resistance are mixed is applied so as to cover the lower end side of the skin board 44 together with the outer surface of the foundation concrete portion 20, and is dried or aligned in the horizontal direction. You may make it apply | coat and dry so that the skin board 44 of the adjacent basic heat insulating material 40 may be hung from the upper end to a lower end. In this case, it is desirable that the fine metal single fibers are mixed in the coating agent so that the fine metal single fibers are densely aggregated to the extent that white ants are not allowed to enter and pass through after drying the paint.
