Is prevented from invading.

(5) The foundation structure according to the present invention may further include an adhesive that is located between the projecting piece and the rising edge and forms a bead extending in the horizontal direction.

The bead, formed by the adhesive and extending horizontally, prevents termites from rising through the gap between the termite-proof sheeted insulation and the rise.

(6) The lower part of the heat insulating material pasted with the anti-termite sheet may be buried in the ground. The basic structure according to the present invention further includes an untreated heat insulating material placed on the exposed upper surface, which is the upper surface of the anti-termite sheet-attached heat insulating material.

According to the above configuration, the amount of anti-termite sheet used can be reduced.

(7) The method of constructing a foundation structure according to the present invention is a method of constructing a foundation structure in which a protective sheet-attached heat insulating material is attached to the foundation. The protective sheet-attached heat insulating material has a rectangular plate-shaped main body and a protruding piece protruding from the main body. The main body has a rectangular plate-shaped heat insulating material and an anti-termite sheet that covers the peripheral surface of the heat insulating material. The protruding piece is formed by an anti-termite sheet. The construction method of the foundation structure is as follows: the first step of placing a foundation having a rise, and the second step of abutting the main surface of the main body with the outer wall surface of the rise to install the anti-termite sheet-attached heat insulating material. It includes a step, a third step of applying an adhesive to the protruding piece of the heat insulating material, and a fourth step of attaching the protruding piece to the rising outer wall surface or the upper surface.

A solid foundation may be used instead of the cloth foundation 11.

The cloth foundation 11 includes a footing 12, a rise 13, and a plurality of anchor bolts 14. The footing 12 is buried underground. The rising edge 13 projects upward from the footing 12. That is, the rising edge 13 projects upward from the ground.

The anchor bolt 14 has a buried portion (not shown) embedded in the rising portion 13 and a bolt portion protruding upward from the buried portion. As shown in FIG. 1, in the placed cloth foundation 11, only the bolt portion of the anchor bolt 14 is visible. In the example shown in FIG. 1, one anchor bolt 14 has two bolt portions.

The bolt portion of the anchor bolt 14 projects upward from the upper surface of the rising edge 13. The plurality of anchor bolts 14 are arranged at equal intervals, for example, along the direction (horizontal direction) in which the rising edge 13 extends.

The base 16 (FIG. 5) is placed on the upper surface of the rise 13. The base 16 has an insertion hole through which the bolt portion of the anchor bolt 14 is inserted. The base 16 is fixed to the cloth foundation 11 by fastening a nut (not shown) to the bolt portion inserted into the insertion hole. A plurality of pillars (not shown) are placed on the upper surface of the base 16 and fixed to the base 16 using fasteners (not shown) such as bolts and nuts. The columns and the base 16 form the frame of the building. Instead of the base 16, the column base metal fittings may be attached to the upper surface of the rise 13 using anchor bolts 14. The column is fixed to the column base metal fitting.

For the cloth foundation 11, for example, as shown in FIG. 2, after laying crushed stone (not shown) in the groove 51 provided on the ground, the waste concrete 52 is placed, and then the formwork 53 is installed along the groove 51. At the same time, after holding the formwork 53 to install reinforcing bars (not shown) and installing the anchor bolts 14 using the support plate 54, ready-mixed concrete is poured into the formwork 53 and placed. The step of placing the cloth foundation 11 is an example of the first step.

As shown in FIG. 3B, the anti-termite sheet-attached heat insulating material 15 includes a heat insulating material 20, a first anti-termite sheet 31 and a second anti-termite sheet 32 attached to the heat insulating material 20. ..

As shown in FIG. 3A, the heat insulating material 20 has a rectangular plate shape, and has a first main surface 21 and a second main surface 22 parallel to each other, a top surface 23 and a bottom surface 24 parallel to each other, and each other. It has a pair of parallel sides 25, 26. The heat insulating material 20 is formed by foaming, for example, one resin or a plurality of resins listed below. As usable resins, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polystyrene (PS), polyvinyl acetate (PVAc), fluororesin (polytetrafluoroethylene) , Acrylic nitrile butadiene styrene (ABS) resin, acrylic nitrile styrene (AS) resin, polymethyl methacrylate (PMMA) and other general-purpose plastics. Further, as usable resins, polyamide (PA), polyacetal (POM), polycarbonate (PC), modified polyphenylene ether (PPE), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), cyclic polyolefin (COP). Engineering plastics such as. Further, as usable resins, heat of polyimide (PI), phenol resin (PF), epoxy resin (EP), melamine resin (MF), urea resin (UF), unsaturated polyester resin (UP), alkyd resin and the like Examples include curable resins. Of the above resins, polystyrene (PS) and acrylonitrile styrene (AS) resins contained in general-purpose plastics, or mixtures thereof, are preferable because they have excellent heat insulating performance and suitable mechanical strength when foamed. .. Further, the heat insulating material 20 can be manufactured by foam molding the above resin by a known method such as extrusion foam molding or in-mold foam molding using a mold, but from the viewpoint of heat insulating performance and mechanical strength, extrusion foam molding Goods are preferred.

The thickness of the heat insulating material 20 is, for example, in the range of several tens of mm to one hundred and several tens of mm. The width of the heat insulating material 20 is in the range of several tens of cm to two hundred and several tens of cm. The height of the heat insulating material 20 is set to be in the range of several tens of cm to two hundred and several tens of cm according to the height of the rising edge 13 of the cloth foundation 11. The heat insulating material 20 is used, for example, by cutting a standard-sized original plate having a thickness of 15 mm to 200 mm, a width of 800 mm to 1000 mm, and a length of 900 mm to 3000 mm according to the specifications of the building.

The first anti-termite sheet 31 and the second anti-termite sheet 32 are a single sheet or a laminated sheet composed of a plurality of layers, and have a thickness in the range of about 10 μm to 800 μm. Preferably, the first anti-termite sheet 31 and the second anti-termite sheet 32 have a thickness in the range of about 10 μm to 400 μm. More preferably, the first anti-termite sheet 31 and the second anti-termite sheet 32 have a thickness in the range of about 40 μm to 80 μm. For example, in the first anti-termite sheet 31 and the second anti-termite sheet 32, an ethylene vinyl acetate copolymer (EVA) resin having a thickness of about 25 μm is laminated as an adhesive layer on a polyethylene terephthalate resin sheet having a thickness of about 50 μm. Is formed.

The first anti-termite sheet 31 is attached to the first main surface 21, the top surface 23, and the bottom surface 24 of the heat insulating material 20 by using an adhesive such as hot melt (FIGS. 4A and 4B). ). The end 33 of the first anti-termite sheet 31 attached to the heat insulating material 20 protrudes from the side where the top surface 23 and the second main surface 22 of the heat insulating material 20 intersect. The end portion 33 of the first anti-termite sheet 31 is attached to the end portion 34 of the second anti-termite sheet 32 to form a protruding piece 42 to be attached to the rising edge 13 of the cloth foundation 11. Details will be described later. A long anti-termite sheet may be cut into a predetermined size and shape using a cutting tool and then attached to the heat insulating material 20 as the first anti-termite sheet 31, or a long anti-termite sheet may be used. After being attached to the heat insulating material 20, the anti-termite sheet may be cut to form the first anti-termite sheet 31. Further, the first anti-termite sheet 31 does not have to be attached to the entire surface of the bottom surface 24 of the heat insulating material 20. The first anti-termite sheet 31 is attached to the bottom surface 24 away from the second main surface 22 in consideration of the attachment of the second anti-termite sheet 32 (FIG. 4 (D)).

The second anti-termite sheet 32 is attached to the second main surface 22 using an adhesive such as hot melt, and is attached to the end portion of the first anti-termite sheet 31 attached to the bottom surface 24 of the heat insulating material 20. , It is attached using the adhesive (FIGS. 4 (C) and 4 (D)). That is, the second anti-termite sheet 32 overlaps with the first anti-termite sheet 31 on the bottom surface 24. In this way, the first main surface 21, the second main surface 22, the bottom surface 24, and the top surface 23 of the heat insulating material 20 are covered with the anti-termite sheets 31 and 32. The first anti-termite sheet 31 and the second anti-termite sheet 32 that cover the heat insulating material 20 prevent the heat insulating material 20 from being eaten by termites.

The end 34, which is one end of the second anti-termite sheet 32, protrudes from the side where the second main surface 22 and the top surface 23 of the heat insulating material 20 intersect, and extends to the end 33 of the first anti-termite sheet 31. , It is attached using the above adhesive. The pasted ends 33, 34 form a protruding piece 42. That is, the ant-proof sheet-attached heat insulating material 15 includes a rectangular plate-shaped main body 41 and a protruding piece 42 protruding from the main body 41. The protruding length of the protruding piece 42 is about 100 mm. After cutting a long anti-termite sheet into a predetermined size and shape using a cutting tool, the long anti-termite sheet may be attached to the heat insulating material 20 as the second anti-termite sheet 32, or the long anti-termite sheet may be used. After being attached to the heat insulating material 20, the anti-termite sheet may be cut to obtain the second anti-termite sheet 32.

As shown in FIG. 3C, the anti-termite sheet-attached heat insulating material 15 has a protruding piece 42 and an extending portion 43 extending laterally from the main body 41. Specifically, the extending portion 43 extends laterally from the protruding piece 42 and faces sideways from the portion of the heat insulating material 20 corresponding to the side where the top surface 23 and the side surface 26 intersect. Has been postponed. The extension length of the extension portion 43 is, for example, in the range of a dozen mm to a hundred and several tens of mm. As shown in FIG. 1, the extension portion 43 is superposed on the adjacent anti-termite sheet-attached heat insulating material 15 when a plurality of anti-termite sheet-attached heat insulating materials 15 are arranged adjacent to each other in the horizontal direction. Details will be described later.

As shown in FIG. 5, the ant-proof sheet-attached heat insulating material 15 is the main surface of the rectangular plate-shaped main body 41, and the main surface corresponding to the second main surface 22 of the heat insulating material 20 is the rising edge of the cloth foundation 11. It is arranged so as to be in contact with the outer wall surface 17 of 13. Then, the projecting piece 42 of the ant-proof sheet-attached heat insulating material 15 is attached to the outer wall surface 17 of the rising portion 13 of the cloth foundation 11 by using the silicon-based adhesive 18. The silicon-based adhesive 18 is applied from one end to the other end of the projecting piece 42 and the extending portion 43 in the horizontal direction. Further, the silicon-based adhesive 18 is applied to the projecting pieces 42 in three rows in the vertical direction. The silicone-based adhesive 18 forms three rows of beads extending in the horizontal direction. Each row is arranged vertically, for example, at intervals of about 25 mm. The three rows of beads prevent termites from reaching the base 16 from between the termite-proof sheet-attached heat insulating material 15 and the rise 13 of the cloth foundation 11. A silicon-based adhesive may also be applied to a portion of the extending portion 43 extending laterally from the top surface 23 of the heat insulating material 20. Further, the silicon-based adhesive 18 is a silicon-based adhesive in a broad sense including a modified silicon-based adhesive.

The construction of the ant-proof sheet-attached heat insulating material 15 will be described in detail with reference to FIGS. 1 and 6. First, as shown in FIG. 6, after the formwork of the foundation structure 10 is removed, the operator sets the level of the heat insulating material 15 with the anti-termite sheet on the outer wall surface 17 of the rising edge 13 (FIG. 6 (A)). ). Next, the operator places the ant-proof sheet-attached heat insulating material 15 on the ant-proof sheet-attached heat insulating material 15 by aligning the upper end of the ant-proof sheet-attached heat insulating material 15 with the level (FIG. 1).

Next, the worker applies an adhesive to the main surface of the main body 41 of the anti-termite sheet-attached heat insulating material 15 and brings it into contact with the outer wall surface 17 of the rising 13 of the cloth foundation 11 to attach the anti-termite sheet-attached heat insulating material 15. It is fixed (Fig. 6 (B)). The step of the worker attaching the anti-termite sheet pasting heat insulating material 15 to the cloth foundation 11 is an example of the second step and the fourth step.

Next, the operator applies the silicon-based adhesive 18 in three rows to the projecting piece 42 and the extending portion 43 of the ant-proof sheet-attached heat insulating material 15. The step of applying the silicone-based adhesive to the projecting piece 42 by the operator is an example of the third step and the second step.

The operator attaches the projecting piece 42 coated with the silicon-based adhesive 18 to the outer wall surface 17 of the rising 13 of the cloth foundation 11 (FIG. 6 (C)), and attaches the extending portion 43 to another adjacent anti-termite. Sheet pasting It is pasted on the protruding piece 42 of the heat insulating material 15. The step in which the worker attaches the projecting piece 42 to the rising portion 13 of the cloth foundation 11 is an example of the fourth step and the third step.

Although not shown in FIGS. 1 and 6, a decorative cover covering the ant-proof sheet-attached heat insulating material 15 may be attached to the cloth foundation 11.

[Action and effect of the embodiment]
In the present embodiment, the peripheral surface of the heat insulating material 20 is covered with the first anti-termite sheet 31 and the second anti-termite sheet 32. Therefore, termites are prevented from invading the inside of the heat insulating material 20.

Further, since the projecting piece 42 formed of the termite-proof sheet and projecting from the main body is attached to the outer wall surface 17 of the rise 13 of the cloth foundation 11, it is possible to obtain from between the termite-proof sheet-attached heat insulating material 15 and the rise 13. Termites are prevented from invading the inside of the foundation structure 10.

Of the two adjacent termite-proof sheet-attached heat insulating materials 15, the extending portion 43 of the projecting piece 42 of one termite-proof sheet-attached heat insulating material 15 overlaps with the projecting piece 42 of the other termite-proof sheet-attached heat insulating material 15. The termites are prevented from invading the inside of the basic structure 10 from between the two ant-proof sheet-pasted heat insulating materials 15.

The bead formed by the silicone-based adhesive 18 and extending in the horizontal direction prevents termites from rising from between the termite-proof sheet-attached heat insulating material 15 and the rise 13 of the cloth foundation 11.

[Modification 1]
In the above-described embodiment, an example in which the protruding piece 42 of the ant-proof sheet-attached heat insulating material 15 is attached to the outer wall surface 17 of the rising 13 of the cloth foundation 11 has been described. However, the projecting piece 42 may be attached to the upper surface of the rising edge 13 as shown in FIG. The operator applies the silicon-based adhesive 18 in a row to the projecting piece 42 in the same manner as in the above-described embodiment, and then attaches the projecting piece 42 to the upper surface of the rising portion 13 of the cloth foundation 11. Then, the operator places the base 16 on the protruding piece 42, and fixes the base 16 to the rising 13 of the cloth foundation 11 by the nut fastened to the bolt portion of the anchor bolt 14. That is, the protruding piece 42 is sandwiched between the rising portion 13 of the cloth foundation 11 and the base 16. Therefore, termites are prevented from invading the base 16 from between the heat insulating material 15 with the anti-termite sheet and the rising edge 13 of the cloth foundation 11.

[Modification 2]
In this modification, as shown in FIG. 8, an example in which the untreated heat insulating material 60 to which the anti-termite sheet is not attached is placed on the anti-termite sheet attached heat insulating material 15 will be described.

The ant-proof sheet-attached heat insulating material 15 is attached to the cloth foundation 11 in the same manner as in the embodiment so that the upper portion is exposed from the ground by several cm to several tens of cm. Then, the untreated heat insulating material 60 is placed on the upper surface of the anti-termite sheet pasted heat insulating material 15 and fixed to the rising 13 of the cloth foundation 11.

In this modification, of the amount of heat insulating material required for heat insulation, the heat insulating material 15 with an anti-termite sheet is used for the part (lower part) where anti-termite is required, and untreated heat insulation is used for the part (upper part) where anti-termite is not required. Material 60 is used. Therefore, the amount of the anti-termite sheet used is reduced as compared with the case where only the anti-termite sheet pasting heat insulating material 15 is used.

[Modification 3]
In this modified example, when the space for attaching the projecting piece 42 cannot be secured on the outer wall surface 17 of the rising 13 of the cloth foundation 11 due to a sash or the like, or when the foundation drainer is installed in advance for remodeling work or the like. A construction method for attaching the anti-termite sheet-attached heat insulating material 15 to the cloth foundation 11 will be described. The configuration other than the configuration described below is the same as the configuration described in the embodiment.

As shown in FIG. 11, the operator folds the projecting piece 42 so that the projecting piece 42 abuts on the main surface of the main body 41. Then, the operator applies the silicone-based adhesive 18 to the projecting piece 42 in three rows on the side opposite to the side that comes into contact with the main body 41. Alternatively, the operator applies the silicone-based adhesive 18 in three rows to the projecting piece 42, and then folds back the projecting piece 42. The operator attaches the projecting piece 42 coated with the silicon-based adhesive 18 to the rising edge 13, and attaches the ant-proof sheet-attached heat insulating material 15 to the rising edge 13.

By constructing the anti-termite sheet-attached heat insulating material 15 as in this modification, even if it is difficult to construct the anti-termite sheet-attached heat insulating material 15 by the construction method of the above-described embodiment, the projecting piece 42 Can be attached to the outer wall surface 17 of the rising edge 13 to carry out the construction of the ant-proof sheet-attached heat insulating material 15.

[Other Modifications] In the above-described embodiment, an example in which the end portion 33 of the first anti-termite sheet 31 and the end portion 34 of the second anti-termite sheet 32 are attached to form the projecting piece 42 has been described. .. However, as shown in FIG. 9, the projecting piece 42 may be formed by a third anti-termite sheet 35 different from the first anti-termite sheet 31 and the second anti-termite sheet 32. More specifically, the operator attaches the first anti-termite sheet 31 to the first main surface 21, the top surface 23, and the bottom surface 24 of the heat insulating material 20 using an adhesive (FIG. 9 (A)). Next, the operator uses an adhesive to attach the second anti-termite sheet 32 to the second main surface 22 of the heat insulating material 20 and the first anti-termite sheet 31 attached to the top surface 23 and the bottom surface 24. Adhere (Fig. 9 (B)). Then, the worker sets the lower end of the third anti-termite sheet 35 to the second anti-termite sheet 32 or the first anti-termite sheet at a position corresponding to the upper end of the second main surface 22 or the first main surface 21 of the heat insulating material 20. It is attached to the ant sheet 31. In the examples shown in FIGS. 9C and 9D, the third anti-termite sheet 35 is attached to the second anti-termite sheet 32. The upper part of the third anti-termite sheet 35 forms a protruding piece 42 to be attached to the rising edge 13 of the cloth foundation 11. In this way, the protruding piece 42 may be formed by the separately attached third anti-termite sheet 35.

In the above-described embodiment, an example in which the first anti-termite sheet 31 is attached to the top surface 23 of the heat insulating material 20 has been described. However, the second anti-termite sheet 32 may be attached to the top surface 23 of the heat insulating material 20. To explain in detail, as shown in FIG. 10A, the worker makes the bottom surface 24 of the heat insulating material 20 and the bottom surface 24 of the heat insulating material 20 so as to protrude from the side where the first main surface 21 and the top surface 23 of the heat insulating material 20 intersect. The first anti-termite sheet 31 is attached to the first main surface 21 using an adhesive. Next, as shown in FIG. 10B, the operator has the first anti-termite sheet 31 attached to the bottom surface 24 of the heat insulating material 20, the second main surface 22 and the top surface 23 of the heat insulating material 20. The second anti-termite sheet 32 is attached to the end portion 33, which is the upper end portion of the first anti-termite sheet 31, using an adhesive. The end 33 of the first anti-termite sheet 31 and the end 34 which is the upper end of the second anti-termite sheet 32 attached to the end 33 are the protruding pieces 42 attached to the rising portion 13 of the cloth foundation 11. To form. In this way, the ant-proof sheet-attached heat insulating material 15 having the projecting piece 42 may be manufactured.

In the above-described embodiment, an example in which the projecting piece 42 and the main body 41 extend to form the extending portion 43 has been described. That is, an example in which the ant-proof sheet-attached heat insulating material 15 has an extension portion 43 in advance has been described. However, the extension portion 43 may be formed by being attached to the anti-termite sheet-attached heat insulating material 15 when the anti-termite sheet-attached heat insulating material 15 is attached to the cloth foundation 11. More specifically, the operator attaches the plurality of anti-termite sheet-attached heat insulating materials 15 to the rising 13 of the cloth foundation 11 by arranging them in the horizontal direction. Then, the operator attaches the anti-termite sheet to the projecting piece 42 and the main body 41 to form the extending portion 43. Even if the extending portion 43 is formed in this way, termites are prevented from entering the inside of the foundation structure 10 from between the two adjacent anti-termite sheet-attached heat insulating materials 15.

In the above-described embodiment, an example has been described in which the pair of side surfaces 25 and 26 of the heat insulating material 20 are not covered with the anti-termite sheet. However, the first anti-termite sheet 31 or the second anti-termite sheet 32 may be attached to one or both of the side surface 25 and the side surface 26 of the heat insulating material 20. For example, the worker attaches the first anti-termite sheet 31 to the side surfaces 25 and 26, and then hot melts the second anti-termite sheet 32 onto the first anti-termite sheet 31 attached to the side surfaces 25 and 26. It is attached using an adhesive such as. By attaching the first anti-termite sheet 31 or the second anti-termite sheet 32 to the side surfaces 25 and 26 of the heat insulating material 20, termites are prevented from invading the inside of the heat insulating material 20 and eating the heat insulating material 20.
