Description

  The present invention relates to a foundation heat insulating structure that can easily and reliably check an ant road formed along a foundation rising portion and can eliminate this at an early stage.

  As a heat insulation method for a floor portion of a building including a house, a floor heat insulation method for constructing a heat insulating material on the floor surface has been generally performed. In recent years, as the demand for higher thermal insulation has increased, instead of this, by installing a heat insulation board such as extruded polystyrene foam on the inside or outside of the foundation, indoor thermal energy can be transferred outdoors through the underfloor space. The use of basic thermal insulation methods to prevent escaping is increasing. This is particularly effective in buildings for cold regions.

  However, when an environment where a certain level of temperature is maintained even in the cold season is formed by making the underfloor insulation space, white ants are damaged even in cold areas where special measures against white ants were not required. May occur.

  Furthermore, if an ant road is formed in the gap between the foundation and the heat insulation board, or if a ant road is formed by making a hole in the heat insulation material preferred by white ants because it is soft and warm, it will be hidden in the heat insulation board. It becomes difficult to find. For this reason, the damage to the building itself has progressed, and wing ants fly around.

  Therefore, as a countermeasure against this, in order to prevent white ants from being damaged by heat insulation boards used for basic heat insulation, a technology has been proposed in which an antifungal agent is blended at the time of manufacturing extruded polystyrene foam or the like constituting the heat insulation boards. (For example, refer to Patent Document 1).

JP 2002-88185-A

  In general, in order to obtain high heat insulation, the heat insulating board must have a sufficiently high foaming ratio of the resin. However, when a large amount of an anti-bacterial agent is blended in the resin, there is a problem that foam molding cannot be performed at a high expansion ratio. For example, in the said patent document 1, the ant preventive agent is mix | blended only about 0.01 to 5% with respect to the foamed resin of about 20 to 50 times of foaming ratio. With such an anti-anticide, sufficient anti-ant performance may not be obtained.

  Further, the foamed resin is a substance that is preferred by white ants to cause damage compared to the non-foamed resin. For this reason, in the foamed resin in which the compounding amount of the termite-preventing agent is suppressed as described above, the white ants may be easily damaged at the stage where the effectiveness of the termite-preventing agent decreases with time.

  The present invention is basically based on forming at least one row of plate-like heat insulating materials that are continuously connected to the foundation riser so as to be detachable, thereby forming an inspection section that can visually inspect the foundation riser for the presence of ant roads. The foundation that can remove ant damage at an early stage by visually checking whether or not ant roads are formed on the surface of the foundation start-up part that is covered with the heat insulating material or inside the heat insulating material. The issue is to provide a heat insulating structure.

  In order to achieve the above object, in the invention according to claim 1, a plate-like heat insulating material is installed on at least one surface of the foundation rising portion that supports the building frame while standing upright from the ground in a wall shape. In the basic heat insulating structure, the plate-like heat insulating material is divided into at least two upper and lower rows, and is configured by arranging heat insulating materials installed in a strip shape on the left and right side, and the plate-like heat insulating material is continuous horizontally. The at least one row is detachably attached to the foundation riser, thereby forming an inspection part capable of visually inspecting the foundation riser for the presence of an ant road.

  In the invention according to claim 2, among the plate-like heat insulating materials that are divided into at least two upper and lower rows and are arranged side by side in the form of a band plate, at least one row of plate-like heat insulating materials arranged side by side has ant-proof properties. In the invention according to claim 3, the plate-shaped heat insulating material having ant-proofing properties is arranged in the lowest row.

  In the invention which concerns on Claim 4, the plate-shaped heat insulating material except the plate-shaped heat insulating material attached detachably among the plate-shaped heat insulating materials divided | segmented into the upper and lower two rows | line | columns and arranged in strip shape on either side is provided. Further, it is characterized in that it is bonded to the foundation rising part using an adhesive having an ant-proofing property.

  In the invention which concerns on Claim 5, it is 30-150 mm from the upper end surface back part by the upper end surface of the plate-shaped heat insulating material arrange | positioned in the row | line | column lower of the said inspection part, and the surface of the foundation raising part exposed by an inspection part. The sheet | seat which has ant-proof property is affixed continuously on the area | region of height L1.

  In the invention which concerns on Claim 6, the sheet | seat which has ant-proof property is 30- along the surface of this plate-shaped heat insulating material from the front edge of the upper end surface of the plate-shaped heat insulating material distribute | arranged to the low order of an inspection part. It has a drooping part that hangs down with a width L2 of 150 mm.

  In the invention according to claim 7, the lowermost plate-like heat insulating material is covered with a sheet having a ant-proofing property at the lower part, and in the invention according to claim 8, the plate-like heat insulating material is on the surface thereof. The exterior plate is laminated integrally.

  In the invention according to claim 1, since the plate-like heat insulating material that is continuous in a horizontal row is detachably attached to the fabric foundation rising portion, the plate-like heat insulating material is removed and the presence or absence of ant roads is confirmed. it can. Therefore, it can be easily and surely checked by eyes whether or not an ant road is formed on the surface of the fabric foundation standing top covered with the heat insulating material or inside the heat insulating material. If an ant road is found, remove the ant road part of the heat insulating material above and below the inspection part, completely remove the ant road, and spray an ant-proofing agent on that part, complete anti-ant treatment Can do.

  As in the invention according to claim 2, when at least one row of plate-like heat insulating materials arranged side by side is configured by using a heat insulating material having an ant-proofing property, even if an ant road is formed halfway, it has an ant-proofing property. The ant road cannot extend above the plate-like heat insulating material. In addition, as in the invention according to claim 3, when the plate-shaped heat insulating materials having ant-proofing properties are arranged in the lowest row, formation of ant roads rising from the ground surface can be effectively suppressed.

  As in the invention according to claim 4, when the plate-like heat insulating material excluding the plate-like heat insulating material that is detachably attached is bonded to the foundation rising portion using an adhesive having an ant-proof property, It is possible to suppress the formation of ant roads that rise between the plate-like heat insulating materials.

  As in the invention according to claim 5, ant-repellent property is continuously provided from the upper end surface of the plate-like heat insulating material at the lower part of the inspection portion and the surface of the foundation rising portion from the upper end deep portion to a constant height region. If a sheet having ant is pasted, even if an ant road is formed from the ground to the lower edge of the inspection part, it is sealed upward by a sheet having ant-proofing properties, so that ant damage is caused to the building body. There is no effect. In addition, since the rising height L1 of the sheet having ant-proofing properties is set to 30 to 150 mm, the gap in which the ant road extends upward is completely sealed, and thus the reliability of the ant-proofing is high.

  As in the invention according to claim 6, when a drooping portion is provided in which a sheet having ant-proofing properties hangs along the surface of the plate-like heat insulating material from the front edge of the upper surface of the plate-like heat insulating material lower than the inspection portion. An ant turn against the ant road rising from the ground along the surface of the heat insulating material is formed. For this reason, the ant road cannot grow above it, and therefore does not cause ant damage to the building rectangle. In addition, since the drooping portion has a width L2 of 30 to 150 mm, complete ant turning is formed, and thus the reliability of the ants is high.

  When the lower part of the lowermost plate-like heat insulating material is covered with an ant-proof sheet as in the invention according to claim 7, an ant repellent effect is obtained at the starting point of the ant road formed upward from the ground. Therefore, the ant-proof effect is great. In addition, as in the invention according to claim 8, when using a plate-like heat insulating material in which exterior plates are laminated integrally, it is possible to prevent foundations simultaneously with finishing of the outer surface of the foundation, so that the appearance of the foundation can be improved and workability can be improved. Excellent.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the basic heat insulating structure 1 includes a basic heat insulating layer 5 attached to one surface of the foundation rising portion 4 and an inspection portion 7 formed on the basic heat insulating layer 5 portion. The

  The foundation rising portion 4 is exemplified by a fabric foundation rising portion in this embodiment, and is erected in a wall shape from the ground 2 by extending upward from a substantially center of the footing 21 provided in the ground 2. A solid foundation is constructed by continuously embedding reinforcing bars in the footing 21 and the foundation riser 4, and a foundation 22 is placed on the upper part to support the building rectangular body 3 such as the outer wall 23 and the floor 24. is doing. In addition, the foundation raising part 4 may be a solid foundation raising part.

  The basic heat insulating layer 5 is used in a basic heat insulating method for preventing indoor heat from escaping to the outside through the underfloor space as described above. It is attached to the inner surface of the part 4 or the outdoor side surface. The foundation heat insulating layer 5 is attached so as to cover at least the entire area from the surface of the ground 2 to the upper end of the foundation rising portion 4. In this embodiment, there is exemplified a case where the ground 2 is further moved down to cover the area up to the upper surface of the footing 21.

  Further, the basic heat insulating layer 5 is constituted by a plate-shaped heat insulating material 6 divided into at least two upper and lower rows, and in this embodiment, three upper and lower rows. The plate-like heat insulating material 6 has a horizontally long belt shape and is continuous from side to side in each row. The plate-like heat insulating material 6 in each row is configured as a horizontally long heat insulating board formed with a predetermined unit length in order to improve the handleability, and is used by being attached to the foundation rising part 4 continuously without a gap. Is done. The length of the heat insulation board is, for example, about 450 to 2100 mm, preferably 900 to 1500 mm, and in this embodiment, 1200 mm. If it is less than 450 mm, the number of joints increases, so that a gap is likely to occur. Conversely, if it exceeds 2100 mm, the handleability deteriorates. Moreover, the thickness of the plate-shaped heat insulating material 6 is formed in about 20-100 mm. Furthermore, when the plate-shaped heat insulating material 6 which adhered the aluminum vapor deposition sheet is used, it is preferable at the point which heat insulation improves further.

  The plate-like heat insulating material 6 is made of the same material as the foamed resin board that is used for heat insulation construction of a normal building, for example, using a styrene resin, a urethane resin, a phenol resin, an acrylic resin, or the like. be able to.

  In this embodiment, a plate-like heat insulating material 6B having ant-proofing properties is used in which at least one row of plate-like heat insulating materials 6 arranged side by side is mixed with an ant-proofing agent in the molding step. As the termite-proofing agent, various kinds of termite-proofing agents employed in the construction technology field can be used. Examples include anti-anticides such as pyrethroids (silafluophene, etofenprox, bifenthrin, etc.), chloronicotinyl (imidacloprid, acetamiprid, clothianidin), carbamates, and organic phosphorus. The compounding amount of the termite-proofing agent varies depending on the required performance and application, but it can usually be blended in the range of 0.01 to 10.0% by weight.

  As described above, by using at least one row of the plate-shaped heat insulating materials 6B having the ant-proofing property, even if ant roads are formed in the region below that, the plate-shaped heat-insulating material 6B having the ant-proofing properties is located above. Since the formation of ant roads is blocked, termites can be prevented from being damaged by the building rectangle.

  Furthermore, in this embodiment, a plate-like heat insulating material 6B having ant-proofing properties is arranged on the lowermost plate-like heat insulating material 6. If comprised in this way, since the formation of the ant road standing up from the ground 2 can be effectively suppressed at the time of start, it is preferable in that the propagation of termites can be more effectively suppressed. Of course, when the plate-like heat insulating material 6B having ant-proofing properties is used for the plurality of rows of plate-like heat insulating materials 6 or all of the plate-like heat insulating materials 6, the reliability of the ant-proof effect can be further improved.

  As the molding method, extrusion molding, cast molding or the like is adopted, and the expansion ratio is set to 15 to 50 times. Further, the expansion ratio is adjusted by the amount of the foaming agent blended in the resin material, heating conditions, extrusion conditions, and the like. When the expansion ratio is large, the heat insulating property is improved. However, when the expansion ratio is too large, the strength tends to be weak. Further, in the molding of the plate-shaped heat insulating material 6B having the ant-proofing property, the expansion ratio is adjusted to a low range of 1.5 to 5 times. If the expansion ratio is too low, the ant-proof function cannot be fully exhibited. If the expansion ratio is too high, it is difficult to mold with a resin material containing a high concentration of the termite-proofing agent.

  The plate-like heat insulating material 6 is bonded to the foundation rising portion 4 leaving a single row (in this embodiment, the middle plate-like heat insulating material 6). As the adhesive used for this, an adhesive used for bonding a general foamed resin can be used. However, when an adhesive having an ant-repellent property mixed with an ant-preventive agent is used, the base rising portion 4 and the plate-like heat insulating material 6 are used. It is preferable at the point which can suppress the formation of the ant road rising between. Examples of the ant-proofing adhesive include asphalt or appropriate emulsion (acrylic or urethane synthetic resin emulsion or SBR synthetic rubber emulsion) adhesive, urethane resin adhesive, modified A silicon-based adhesive, a moisture-curing adhesive, or the like mixed with an anti-anticide similar to the above is used. More specifically, an adhesive (trade name: Termite Glue IM, manufactured by Oshika Co., Ltd.) in which 0.1% by weight of imidacloprid as an anti-anticide is blended with an acrylic adhesive can be used.

  The remaining one row of the plate-like heat insulating materials 6 other than the plate-like heat insulating materials 6 bonded as described above is detachably attached to the foundation rising portion 4. In this embodiment, as shown in FIG. 1 and FIG. 2 (A), the middle row of plate-like heat insulating materials 6 are arranged between the plate-like heat insulating materials 6 arranged vertically and fixed to the foundation rising portion 4. Is inserted into the recess formed. And, it is fixed by driving a U-shaped nail-shaped stopper 25 between the upper and lower plate-like heat insulating materials 6.

  Therefore, the interrupted plate-like heat insulating material 6 can be easily removed from the foundation rising portion 4 by pulling out the stopper 25 and pulling it forward as shown in FIGS. 1 and 2B. In this way, by removing the plate-like heat insulating material 6 that is detachably attached to the surface of the foundation riser 4, the inspection part 7 that the foundation riser 4 is partially exposed is formed. It is possible to confirm whether or not an ant road has been formed by visually checking the inspection portion 7 formed by removing the plate-like heat insulating material 6. That is, it is possible to easily and surely check whether or not an ant road is formed on the surface of the foundation rising portion 4 that is covered and hidden by the basic heat insulating layer 5 and the inside of the basic heat insulating layer 5. Moreover, when an ant road is discovered, the ant road part of the plate-shaped heat insulating material 6 arrange | positioned at the upper and lower sides of the inspection part 7 can be removed, and an ant road can be removed completely. Furthermore, it is possible to prevent ant roads from being formed again by performing an ant protection treatment such as spraying an ant protection agent on the spot.

  In addition, the inspection part 7 means the opening part pinched by the upper and lower plate-shaped heat insulating materials 6 which can see the foundation stand-up part 4 directly by removing the plate-shaped heat insulating material 6 which can be attached or detached as mentioned above. However, by attaching the plate-like heat insulating material 6 in a horizontal row so as to be detachable, an area of the plate-like heat insulating material 6 in which an opening for checking the presence or absence of an ant road can be easily formed may be indicated.

  Other than using the U-shaped nail-shaped stopper 25, as means for detachably attaching the plate-like heat insulating material 6 of the inspection part 7, for example, a female part provided with a large number of small loops and a detachable means for the receiving part. A so-called hook-and-loop fastener composed of a male portion provided with a large number of small key pieces that can be combined can be formed by being attached to the facing portions of the foundation rising portion 4 and the plate-like heat insulating material 6, respectively. Alternatively, the plate-like heat insulating material 6 disposed in the inspection unit 7 is formed on the lower end surface of the upper plate-like heat insulating material 6 and the upper surface of the lower plate-like heat insulating material 6. The upper and lower ends may be provided with stepped portions that respectively fit into the receiving stepped portions, and the noodle type fixing means for engaging the stepped portions with the receiving stepped portions may be used.

  In the check operation of the ant road, the plate-like heat insulating material 6 disposed in the inspection unit 7 is sequentially removed in the lateral direction, and the foundation rising unit 4 is inspected over the entire length. It is also possible to focus on checking only places around the water, such as bathrooms, kitchens and toilets, or where there is a suspicion of ant road formation.

  In this embodiment, a sheet 8 having ant-proofing properties is pasted continuously from the upper end portion of the plate-like heat insulating material 6 disposed below the inspection portion 7 to the foundation rising portion 4 exposed in the inspection portion 7. I wear it. In addition, the sheet | seat 8 which has the above ant-proof property is a name for distinguishing from the sheet | seat which has the ant-proof property used for another site | part.

  As for the sheet having ant-proofing properties, a synthetic resin sheet having moisture-proofing properties such as polypropylene, polyethylene, and ethylene vinyl acetate is used, and pyrethroid-based, chloronicotinyl-based, carbamate-based, organic phosphorus-based, etc. What mixed and selected the effective thing from the ant agent is suitable. However, as the base material of the sheet, for example, a non-moisture-proof material such as a nonwoven fabric can be adopted. As the adhesive used for the sticking, the same adhesive used for bonding the plate-like heat insulating material 6 can be used. Also in this case, it is preferable to use an ant-proofing adhesive containing an ant-proofing agent.

  Thus, the sheet | seat 8 which has the top ant-proof property is made into the upper end surface of the plate-shaped heat insulating material 6 of the inspection part 7 lower part, and the area | region of the fixed height from the said upper end part back part on the surface of the foundation raising part 4. Even if an ant road is formed from the ground 2 to the lower edge of the inspection part 7 by being hidden by the plate-like heat insulating material 6, the sheet 8 having the above-mentioned ant-proof property is further directed upward. Therefore, the ant road is prevented from extending further. Therefore, ant damage to the building rectangular body 3 can be prevented.

  As shown in FIG. 2 (B), the rising height L1 of the above-mentioned sheet 8 having ant-repellent property is, for example, about 30 to 150 mm, preferably 50 to 120 mm, and 90 mm in this embodiment. If it is less than 30 mm, the above-mentioned sheet 8 having ant-repellent property is easy to peel off, so that there is a possibility that an ant road is formed through, and conversely if it exceeds 150 mm, it becomes an excessive dimension for the ant-proof effect, The workability of the sticking work is reduced.

  Moreover, the sheet | seat which has the ant-proof property on this form is constant along the surface of this plate-shaped heat insulating material 6 from the front edge of the upper end surface of the plate-shaped heat insulating material 6 distribute | arranged to the low order of the inspection part 7. A drooping portion 8T that hangs down with a width L2 is formed continuously. If such a hanging part 8T is provided, when the ant road is formed along the surface of the plate-like heat insulating material 6 rising from the ground 2 under the floor, the hanging part 8T becomes an ant-repellent to the ant road, Can't grow above the point. Therefore, it is preferable in that it does not cause ant damage to the building rectangular body 3.

  As shown in FIG. 2 (B), the width L2 of the sagging portion 8T of the above-mentioned sheet 8 having ant-proofing properties is, for example, about 30 to 150 mm, preferably 50 to 120 mm, and in this embodiment, 90 mm. If it is less than 30 mm, there is a case where the function as an ant is not sufficient, and there is a possibility that the ant road extends further beyond the drooping portion 8T. Length.

  Furthermore, the sheet | seat 8 which has the ant-proof property on this form is formed using the transparent or translucent synthetic resin sheet base material. Thus, when the sheet | seat 8 which has the above ant-proof property has transparency, as shown in FIG.2 (B), when carrying out the visual check of the inspection part 7, the foundation stand-up part 4, the plate-shaped heat insulating material 6, And the upper end surface of the plate-like heat insulating material 6 can be clearly confirmed, and the ant road is not overlooked, so that the reliability of the inspection work is improved and the workability is high because the inspection can be performed at a glance.

  In this form, by the sheet | seat 9 which has the ant-proof property of the lower part arrange | positioned in the cross-section L-shape along the cross | intersection part with the surface where the foundation heat insulation layer 5 of the foundation raising part 4 is attached, and the said footing 21. The lower part of the plate-like heat insulating material 6 which is arranged at the lowest position and whose lower end is embedded in the ground 2 is covered. The lower sheet 9 having ant-proofing properties may further rise along the outer surface of the plate-like heat insulating material 6 to cover the lower portion of the plate-like heat insulating material 6 in a horizontal U shape. Or it can also comprise so that the lower part of the lowermost plate-shaped heat insulating material 6 may be covered by the edge part of the ant-proof sheet | seat laid in the whole ground 2 surface under the floor. Thus, when the lower part of the lower plate-like heat insulating material 6 is covered with the lower ant-proof sheet 9, the ant repellent effect at the starting point of the ant road formed upward from the ground 2 is the starting point. Therefore, since the formation of ant roads can be effectively prevented, a great ant protection effect can be obtained.

  FIG. 3 illustrates another embodiment. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. The basic heat insulating structure 1 of the present embodiment is configured by using plate-like heat insulating materials 6 divided into two upper and lower rows, and the upper plate-like heat insulating material 6 is detachably attached to the base rising portion 4, An inspection unit 7 is formed. Specifically, a support bar 28 is fixed to the lower portion of the large pull 26 with a small space 27 between the base riser 4 and the support frame 28. The upper part of the plate-shaped heat insulating material 6 is supported by being inserted into the small gap 27, and the lower end portion is placed on the upper end surface of the lower plate-shaped heat insulating material 6, and the same U-shaped nail shape as described above. It is detachably attached by driving a stopper (not shown) to form an inspection part 7.

  FIG. 4 illustrates yet another embodiment. In this embodiment, a plate-like heat insulating material 6 is attached to the outdoor side of the foundation rising portion 4 to constitute a foundation that is thermally insulated outside. On the outer surface of each plate-like heat insulating material 6, the same size exterior plate 10 is integrally laminated to ensure weather resistance and improve the appearance of the foundation. As the exterior board 10, tiles, various siding boards, metal plates such as aluminum, and other various boards can be used. And the plate-shaped heat insulating material 6 and the exterior board 10 are integrated previously by adhesion | attachment.

  In the present embodiment, among the plate-like heat insulating materials 6 divided into three rows, the plate-like heat insulating materials 6 with the exterior plates that are arranged above and below are each fixed to the foundation rising portion 4 by adhesion. As shown in FIG. 5, the middle plate-like heat insulating material 6 has attachment legs 30 extending through the plate-like heat insulating material 6 from the anchor plate 29 disposed on the boundary surface between the exterior plate 10 and the plate-like heat insulating material 6. Projecting toward the back. On the other hand, a small hole 31 is formed in the middle of the foundation rising portion 4. By pressing the mounting legs 30 of the plate-like heat insulating material 6 into the small holes 31, the plate-like heat insulating material 6 with an interrupted exterior plate is detachably attached, and the inspection portion 7 is attached to the outdoor surface of the foundation rising portion 4. Is formed. Thus, when the plate-shaped heat insulating material 6 which laminated | stacked the exterior board 10 integrally is used, it is excellent in workability | operativity since it can perform a foundation ant at the same time as the finishing of the outer surface of a foundation, and it can improve the appearance of a foundation.
