Description

  The present invention relates to a heat insulating structure for a concrete foundation of a building, in particular, a basic heat insulating structure having an insect repellent / ant repellant function, and an insect repellent molded body used therein.

  In recent years, for the purpose of energy saving, a heat insulating material is disposed on the outer side surface or the inner side surface of a concrete foundation of a building. The concrete foundation may be a fabric foundation or a solid foundation. As the heat insulating material, a plate-like synthetic resin foam is mainly used, but a board formed from an inorganic material such as glass wool or rock wool is also used. If some of the heat insulating material placed on the side of the concrete foundation is in the ground, it may be damaged by pests, especially white ants.

  For example, when the heat insulating material is a synthetic resin foam, it is broken by white ants, and due to the behavior of white ants, ant roads are formed in the heat insulating material from the bottom to the top. As a result, the heat insulation performance is reduced, and the white ants pass through the wood base on the concrete foundation. When the heat insulating material is glass wool, rock wool or the like, the white ants will rise upward through the voids present inside, and the wood base will be damaged.

  For this purpose, several basic heat insulation structures have been proposed in which the heat insulating material arranged on the side surface of the concrete foundation is not damaged by white ants. For example, in Patent Document 1 and Patent Document 2, when the formwork is assembled, the outdoor surface of the heat insulating material to be disposed on the side surface of the concrete foundation is covered with the ant-proof sheet, and the lower end side of the ant-proof sheet is covered with the heat-insulating material. The bottom edge of the ant-proof sheet is bitten into the concrete foundation (cloth foundation) by placing the concrete for the concrete foundation in that state. Thereby, white ants are prevented from entering the heat insulating material from between the surface and lower end surface of the heat insulating material and the cloth foundation.

  Patent Document 3 describes a basic heat insulating structure in which a basic heat insulating material is attached to the outdoor side of a fabric foundation of a building after construction. A metal plate or a resin plate is attached to the base of the rising portion of the cloth foundation. A white ant shield plate formed by bending is placed, and a basic heat insulating plate and a surface decorative material are attached thereon. Further, if necessary, the space between the white ant shield plate and the fabric foundation is sealed with an ant-proof sealing material. This white ant shielding plate (and ant-proof sealing material) also prevents white ants from entering the heat insulating material from between the lower end surface of the heat insulating material and the fabric foundation.

  The thing of patent document 1 or patent document 2 is made to integrate an ant-proof sheet | seat into a concrete foundation simultaneously with the placement of the concrete for concrete foundations, and workability | operativity improves. In addition, the bottom edge of the ant-proof sheet is made to bite into the concrete foundation (cloth foundation), and when the bite is sufficient, it prevents white ants from reaching the insulation material between the concrete foundation. can do. However, since the ant-proof sheet is sheet-like and does not have sufficient rigidity, it is easily deformed by the concrete pouring pressure, and therefore, the lower end edge of the ant-proof sheet is placed at an appropriate position when placing concrete. It is practically impossible to cut in with the required depth. For this reason, the mounting stability between the lower end portion of the heat insulating material and the concrete foundation becomes insufficient, and the intrusion of white ants may occur.

  The thing of patent document 3 is trying to attach a white ant shielding board and a base heat insulation board to the side surface of the completed cloth foundation by post-operation, and an operation amount becomes large. Further, the white ant shield plate and the rising portion of the fabric foundation are merely in contact with each other, and the positional deviation is likely to occur. In addition, since a white ant shield plate or the like is attached in the post-operation, a gap is likely to be formed between the fabric foundation and the white ant shield plate (or an ant-proof sealing material), and an ant entry path may be formed. . The ant-proof sealant will also become thin and deteriorate.

  The present invention has been made in view of the circumstances as described above, and at the time of placing concrete, it is possible to simultaneously perform the arrangement of the heat insulating plate with respect to the concrete foundation and the insect-repellent measures for the heat insulating plate, An object of the present invention is to provide a more improved basic heat insulating structure in which the attachment stability of the insect-proof molded body used for the insect-control measures to the concrete foundation is improved, and an insect-proof molded body used therein.

  The base heat insulating structure in which the heat insulating material is arranged on the side surface of the concrete foundation according to the present invention is a state in which the lower end region of the heat insulating material is covered with an insect repellent molded body having at least the following configurations a) to d) and The heat insulating material is arranged on the side surface of the concrete foundation in a state where the concrete engaging portion of the body is embedded in the concrete foundation.

a) an outer insect repellent part covering at least the outer surface embedded in the ground of the heat insulating material;
b) a lower insect repellent part covering the lower end surface of the heat insulating material;
c) A concrete inflow prevention portion that rises from the bottom insect repellent portion so as to cover the inner surface of the heat insulating material,
d) A concrete locking portion that rises diagonally upward from the horizontal from the bottom insect repellent portion or the concrete inflow prevention portion.

  Furthermore, the present invention also discloses an insect repellent molded body used in a basic heat insulating structure in which a heat insulating material is arranged on the side surface of the concrete foundation described above, and having at least the following configurations a) to d).

a) an outer insect repellent part covering at least the outer surface embedded in the ground of the heat insulating material;
b) a lower insect repellent part covering the lower end surface of the heat insulating material;
c) Concrete inflow prevention part rising from the bottom insect repellent part,
d) A concrete locking portion that rises diagonally upward from the horizontal from the bottom insect repellent portion or the concrete inflow prevention portion.

  In the foundation thermal insulation structure according to the present invention, when the concrete foundation mold is assembled, the thermal insulation is arranged at the lower side of the side of the concrete foundation where the thermal insulation is to be arranged. a socket portion of the insect-proof molded body provided with a) to d), that is, in a state where it is inserted into a portion formed by the outer insect-proof portion, the lower-end insect-proof portion and the concrete inflow prevention portion, and the concrete locking portion is a concrete placement space Arrange it so that it is on the side.

  After assembling the mold with the heat insulating material and the insect-proof molded body integrated, concrete is placed in the mold. The placed concrete is swallowed by the concrete locking portion of the insect-proof molded body and enters the concrete placing space. If necessary, fill concrete with vibration. The lower end surface area of the concrete placement space side (inner surface) of the heat insulating material is in close contact with the concrete inflow prevention portion that rises from the lower insect repellent portion so as to cover the inner surface of the heat insulating material, and the concrete enters between them In addition, the heat insulating material is not lifted by the buoyancy of the placed concrete.

  In the state in which the placed concrete is hardened, the concrete locking portion of the insect-proof molded body surely enters the concrete in an immobile state, and the attachment mode between the concrete foundation and the insect-proof molded body is extremely stable. As a result, the mounting mode between the concrete foundation and the heat insulating material is also stable.

  At least the outer surface embedded in the ground of the heat insulating material is covered with the outer insect-proofing portion of the insect-proof molded article, and no harmful insects enter the heat insulating material from there. The lower end surface of the heat insulating material is covered with the lower insect repellent portion of the insect repellent molded body, and the cast concrete hardens in a state of being in close contact with the lower end insect repellent portion. There are no gaps between them, and no pests can enter the concrete foundation. Even if it enters and climbs between the concrete inflow prevention part of the insect-proof molded body and the concrete foundation, the concrete inflow prevention part of the insect-proof molded body becomes a major obstacle, and the intrusion of further pests is blocked. .

  As described above, the basic heat insulating structure according to the present invention can simplify the construction and can almost completely prevent pests from reaching the wooden foundation of the building through the heat insulating material.

  In the basic heat insulating structure according to the present invention, when two or more insect-proof molded bodies are used in the lateral direction, the edges of adjacent insect-proof molded bodies are fitted to each other. They are preferably connected by a bonding material having stop portions on both sides. By connecting using such a joined body, it is possible to effectively prevent pests from entering the heat insulating material side from the joined surface of the adjacent insect-proof molded bodies.

  In the basic heat insulating structure according to the present invention, it is preferable that the outer wall surface of the heat insulating material and the region above the region covered with the outer insect-proof portion of the insect-proof molded body is covered with the exterior material. Thereby, the protection of the insulation is more complete. As the exterior material, a material generally used as a building exterior material such as slate, mortar, concrete, etc. may be used. These exterior materials are attached to the heat insulating material surface by adhesion, coating, spraying, or the like. In the case of applying a water curable material such as mortar, it is effective to use a lath wire mesh, a mesh or the like, and it is possible to effectively prevent the occurrence of cracks.

  Moreover, depending on the structure of the building, it is also desirable to cover the upper end surface of the heat insulating material with an insect-proof plate. Thereby, the invasion of pests from the upper end surface of the heat insulating material can also be prevented, and the pest control becomes more complete. The material of the insect repellent plate may be the same material as the insect repellent molded body, or a commercially available ant repellent sheet may be used.

  In the basic heat insulating structure according to the present invention, the material of the heat insulating material is not particularly limited. However, from the viewpoint of high heat insulating properties and ease of construction, it is preferable to synthesize polystyrene foam, polyurethane foam, polyethylene foam, polypropylene foam, phenol foam, and the like. A resin foam is mentioned. The expansion ratio can be arbitrarily selected according to the required heat insulation performance. Board-like inorganic heat insulating materials such as glass wool and rock wool can also be used.

  The material of the insect-proof molded body used in the basic heat insulating structure according to the present invention is a material having the required self-holding property and strength, and it can be eaten by pests against building materials such as termites, oyster beetles, Nagashinkai, Shibamushi, etc. Any material can be used as long as it is not capable of being affected by the secretions of these pests. Examples include inorganic molded products such as metals such as stainless steel, ceramics, and cement products, FRP, polystyrene, polyvinyl chloride, and polycarbonate. For example, a plastic-based molded body. From the viewpoint of moldability, a plastic molded body is preferable.

  The thickness of the insect-proof molded body is preferably about 1 to 5 mm although it depends on the material. If it is 1 mm or less, the rigidity may be insufficient and the concrete may be deformed at the time of placing the concrete. If it is 5 mm or more, the gap with the formwork plywood may become large, which may hinder the construction. However, even in this case, the problem is solved if the gap between the heat insulating material and the mold is adjusted with the face material.

  The angle range of the concrete engaging portion that rises obliquely upward upward from the horizontal in the insect-proof molded body is preferably in the range of 20 to 80 degrees, and preferably in the range of 30 to 60 degrees. When the angle is 20 degrees or less, the concrete is difficult to rotate under the concrete locking portion when the concrete is placed. If it is 80 degrees or more, there is a possibility that the concrete will not easily be clogged on the upper side of the concrete locking portion and a cavity may be formed, which is not preferable. The length of the concrete locking portion is preferably 10 mm or more, and more preferably in the range of 20 to 30 mm. If it is 10 mm or less, the adhesion to the foundation concrete may be insufficient. On the other hand, when the thickness is 30 mm or more, there is a fear that the concrete is insufficiently filled on the back surface.

  In the insect-proof molded article, it is preferable that a through hole is formed in the concrete locking portion. The concrete placed through the through-hole is likely to flow into the lower side of the concrete locking portion, and conversely, it is easy to release the internal air. It will be even more certain. The shape and size of the through hole may be any shape as long as the concrete flows into it. In order to increase fluidity, it is desirable that the base is a semicircle, a trapezoid, or a triangle, and the bottom is the base of the concrete locking portion. The size is not particularly defined, but is preferably about 10 to 20 mm.

  Preferably, the protrusion which fixes a heat insulating material to the said concrete inflow prevention part in an insect-proof molded object is provided. The protrusion is preferably in a triangular shape protruding obliquely downward, and preferably has a side of about 5 to 10 mm. When smaller than this, the effect which fixes a heat insulating material will fade, and when larger than this, the insertability of a heat insulating material will worsen.

  The basic heat insulating structure according to the present invention is constructed by attaching an insect repellent molded body having a protrusion embedded in concrete to the lower end of the heat insulating material, setting it in a basic formwork, and pouring the concrete, so that the insect repellent molding The body comes into close contact with the foundation concrete, which makes it possible to completely close the gap where the pests enter.

  Hereinafter, the present invention will be described based on some embodiments with reference to the drawings. First, the insect-proof molded body used in the basic heat insulating structure according to the present invention and the bonding material used to join the edges of adjacent insect-proof molded bodies will be described. 1 to 3 are perspective views illustrating the insect-proof molded article, and FIG. 4 is a perspective view of a bonding material.

  FIG. 1a is a perspective view showing an example of the insect-proof molded body, and FIG. 1b is a cross-sectional view taken along the line bb of FIG. 1a. In this example, the insect-proof molded body 1 is an extruded product of stainless steel having a thickness of about 2 mm, and covers at least the outer surface embedded in the ground of the heat insulating material used in the basic heat insulating structure to be constructed in close contact. A flat plate-shaped outer insect repellent part 2 and a lower end insect repellent part 3 extending in a horizontal direction from the lower end part of the outer insect repellent part 2 which also covers the lower end surface of the heat insulating material in close contact with each other, The concrete inflow prevention part 4 which stands | starts up from the said lower end insect-proof part which covers the inner surface of a heat insulating material closely is provided.

  On the outer surface of the concrete inflow prevention portion 4, a concrete engagement portion 5 that rises obliquely upward upward at an angle of approximately 45 degrees from a horizontal plane is integrally formed. A plurality of semicircular through holes 6 having a radius of about 10 to 20 mm are formed at a predetermined interval on the side of the concrete engaging portion 5 in the connecting portion with the portion 5. The shape of the through hole 6 is not limited to a semicircular shape, and may be arbitrary, and the through hole 6 itself may be omitted.

  The size of the insect-proof molded body 1 is such that the lower end portion side of the heat insulating material used in the basic heat-insulating structure is formed by the socket portion of the insect-proof molded body 1, that is, the outer insect-proof portion 2, the lower-end insect-proof portion 3 and the concrete inflow prevention portion 4. In addition, the size is appropriately set to be inserted in a close state. The length in the longitudinal direction may be arbitrary, and if necessary, two or more insect-proof molded bodies 1 are connected and used at a construction site with a bonding material described later. It is preferable that the protrusion distance of the concrete inflow prevention part 4 is about 20-30 mm. Although not shown, the concrete locking portion 5 may be formed so as to extend from the lowermost end portion of the concrete inflow prevention portion 4, in other words, from the lower end insect-proofing portion 3.

  FIG. 2 shows another example of the insect-proof molded article. This insect-proof molded body 1A is shown in FIG. 1 in that the concrete inflow prevention portion 4 is formed with triangular projections 7 with one side protruding about 5-10 mm at a predetermined interval. It differs from the insect-proof molded object 1 shown. Other members are the same as those of the insect-proof molded body 1 shown in FIG. When the heat insulating material is assembled to the insect-proof molded body 1A, the protrusions 7 are inserted into the heat insulating material, and unnecessary movement of the heat insulating material can be prevented.

  FIG. 3 shows still another example of the insect-proof molded article. This insect repellent molded body 1B is different from the insect repellent molded body 1 shown in FIG. 1 in that the second concrete engaging portion 8 is integrally formed with the concrete engaging portion 5. Other members are the same as those of the insect-proof molded body 1 shown in FIG. The second concrete locking portion 8 is for increasing the contact area between the concrete locking portion 5 and the concrete to be placed and stabilizing the insect-proof molded body 1. In the illustrated example, Although the 2nd concrete latching | locking part 8 is formed in the upper surface of the concrete latching | locking part 5 as one vertical board piece, the number and shape are not restricted to this. It can also be provided on the lower surface side of the concrete locking portion 5.

  In the construction site, the above-described insect-proof molded body 1 (or 1A, 1B) may be continuously arranged in the lateral direction. FIG. 4 shows a bonding material used as necessary at that time, FIG. 4a is a perspective view, and FIG. 4b is a cross-sectional view taken along line bb of FIG. 4b. The bonding material 10 is made of the same material as that of the insect-proof molded body 1 and has substantially the same cross-sectional shape as the insect-proof molded body 1 as a whole. The width W is about 10 to 20 cm, and as shown in FIG. 4a, on both the left and right sides thereof, fitting members in which the edges of the two insect-proof molded bodies 1a and 1b to be connected are fitted internally. Stop portions 11a and 11b are formed. Although not shown, the fitting locking portions 11a and 11b are at an angle of 90 degrees so that the left and right insect-proof molded bodies 1a and 1b can be connected at the corners (protruding corners and entering corners) in the heat insulating basic structure. It is also possible to employ a joined body that has a crossing direction.

  Next, a basic heat insulating structure constructed using the insect-proof molded body 1 will be described. First, make a formwork for the basic insulation structure. FIG. 5 shows an example of a formwork in the case where the concrete foundation is a cloth foundation 20. A plywood formwork is used to drive a formwork 31 of the enlarged foundation part 21 of the cloth foundation and a formwork of the rising part 22. 32 is built. At that time, in the part which becomes the side wall of the concrete foundation (cloth foundation) on which the heat insulating material 40 is to be arranged, in the example shown in FIG. 5, on the concrete placing space side of the placing form 32 a corresponding to the right side wall part of the rising portion 22. For example, a heat insulating material 40 made of synthetic resin foam is disposed. When the heat insulating material 40 is arranged, the insect-proof molded body 1 is fitted into the lower end side of the heat insulating material 40, and the concrete inflow preventing portion 2 side of the fitted insect-proof molded body 1 is on the concrete placing space side so It integrates with the frame 32a. In FIG. 5, 23 is a split chestnut, 24 is a reinforcing bar for a concrete foundation (cloth foundation), 33 is a vertical end material, 34 is a horizontal end material, 35 is a fastener for a formwork, 36 is a separator, 37 is These are joiners, both of which have been conventionally used as formwork forming materials for concrete foundations and the like.

  After building the formwork as shown in FIG. 5, the cast-in-place concrete is placed in the concrete placement space. The concrete flows around the concrete locking portion 5 formed in the concrete inflow prevention portion 4 and flows into the mold while passing through the through hole 6 formed there. When the placed concrete is hardened, the heat insulating material 40 is integrated with the concrete together with the insect-proof molded body 1. In the curing process, the bottom insect repellent portion 3 of the insect repellent molded body 1 is in close contact with the concrete surface that becomes the enlarged base portion 21, and the concrete locking portion 5 formed on the concrete inflow preventing portion 4 is in the cured concrete. It is in a state of being embedded in and firmly fixed. Thereby, the insect-proof molded body 1 and the heat insulating material 40 fitted therein are stably fixed to the side surface of the concrete foundation.

  FIG. 6 shows an example in which a wooden house 50 is built on the concrete foundation (cloth foundation) 20 after the mold is removed so that the heat insulating material 40 side is on the outside. After demolding, the soil 24 is backfilled, and the middle of the enlarged foundation portion 21 and the rising portion 22 of the concrete foundation 20 is buried in the soil. In the illustrated example, the soil is backfilled to a height at which the middle of the outer insect-repellent portion 2 of the insect-repellent molded body 1 attached to the heat insulating material 40 is at the ground level G.

  On the rising portion 22 of the concrete foundation 20, a wooden foundation 51 of a wooden house 50 is placed horizontally, a large pull 52 and a joist 53 are attached, and a flooring 54 is laid thereon. Further, a pillar 55 is erected on the wooden foundation 51, and a heat insulating material 41 is attached to the outer surface of the pillar 55, and the heat insulating material 40 and the heat insulating plate 40 attached to the side surface of the rising portion 22 of the concrete foundation 20 are covered. Thus, the outer wall material 56 is attached. As shown in the drawing, the outer wall material 56 covers the entire outer surface of the heat insulating plate 40 and not covered by the outer insect-proof portion 2 of the insect-proof molded body 1.

  In the wooden house 50 equipped with this concrete foundation structure, the outer surface of the heat insulating material 40 and the portion embedded in the ground is covered with the outer insect repellent portion 2 of the insect repellent molded body 1, Such a pest does not enter the heat insulating material 40. The lower end surface of the heat insulating material 40 is also covered by the lower end insect repellent portion 3 of the insect repellent molded body 1, and the lower end insect repellent portion 3 is in close contact with the upper surface of the enlarged base portion 21 of the concrete foundation 20. It does not enter the material 40. Even if it enters from there, due to the presence of the concrete locking portion 5 attached to the concrete inflow prevention portion 4 of the insect repellent molded body 1, the insect repellent molded body 1 is firmly fixed to the rising portion 22 of the concrete foundation 20. Thus, white ants do not enter the heat insulating material 40 from the back side. Therefore, the heat insulation of the heat insulation 40 is not deteriorated by the formation of the ant road, and damage to the wooden foundation 51 of the wooden house 50 by the white ants can be almost completely avoided.

  FIG. 7 shows another example of the basic heat insulating structure according to the present invention. In this example, the heat insulating material 40 </ b> A is attached to the entire outer surface of the concrete foundation (cloth foundation) 20, and the insect-proof molded body 1 </ b> A is attached to the lower end region of the heat insulating material 40. Other configurations are the same as those shown in FIG. 6, and the same members are denoted by the same reference numerals. That is, here, the heat insulating material 40 </ b> A includes the first heat insulating material 42 covering the side wall of the rising portion 22 of the concrete foundation 20, the second heat insulating material 43 covering the upper surface of the enlarged base portion 21, and the side surface of the enlarged base portion 21. It is comprised with the 3rd heat insulating material 44 to cover. And the part corresponding to "the outer insect-repellent part which covers at least the outer surface embedded in the ground of the heat insulating material" of the insect-proof molded body 1A also corresponds to the first heat insulating material 42 from the outside. The outer insect repellent part 2a, the second outer insect repellent part 2b that covers the second heat insulating material 43 from the outside, and the third outer insect repellent part 2c that covers the third heat insulating member 44 from the outer side. The outer insect repellent part 3 extends horizontally from the lower end of the third outer insect repellent part 2c, and the concrete inflow preventing part 4 extends upward from the tip of the outer insect repellent part 3. The same as the body 1.

  In this heat insulating foundation structure, the concrete locking portion 5 of the insect-proof molded body 1A is embedded in the enlarged base portion 21 of the concrete foundation 20, but the effect of preventing white ants from entering the heat insulating material 40A, the heat insulating material 40A and the insect-proofing material. The attachment stability of the molded body 1A to the concrete foundation 20 is the same as that shown in FIG.

  FIG. 8 shows still another example of the basic heat insulating structure according to the present invention. In this example, it differs from what was shown in FIG. 6 by the point which has attached the heat insulating material 40 to the inner surface in the standing | starting-up part of the concrete foundation (cloth foundation) 20. FIG. The outer insect repellent portion 2 of the insect-repellent molded body 1 has its upper edge reaching the upper end of the heat insulating plate 40 so as to cover the entire side surface of the heat insulating plate 40. Other configurations are the same as those shown in FIG. 6, and the same members are denoted by the same reference numerals. In the case of this configuration, as shown in the figure, there may be a structure in which the upper end surface of the heat insulating material 40 comes into contact with the large pull 52 of the building. In that case, it is conceivable that the white ants climb along the outer insect repellent portion 2 of the insect-repellent molded body 1 and reach the large pull 52 or the like. Assuming such a case, the upper end surface of the heat insulating material 40 is covered with an insect repellent plate 60 made of the same material as the insect repellent molded body 1.

  FIG. 9 shows still another example of the basic heat insulating structure according to the present invention. This example is different from the basic heat insulating structure shown in FIG. 6 in that the concrete foundation is a solid foundation 20A. And the heat insulating material 40 is attached to the whole outer side surface of the rising part 22A of the solid foundation 20A. Other configurations are the same as those shown in FIG. 6, and the same members are denoted by the same reference numerals.
