  In the heat insulation structure of the building as described above, the rectangular plate-shaped ant-proof heat insulating materials are arranged so as to be arranged in the circumferential direction on the outer peripheral surface of the foundation, and the ant-proof heat-insulating materials adjacent in the lateral direction are adhesives, It is generally bonded with an amorphous sealing material or an ant-proof sealing material in which an ant-proofing agent such as a termite repellent is added to the sealing material.

  Moreover, a gap through which termites can pass often occurs at the joints between the ant-proof heat insulating materials adjacent in the lateral direction due to the dimensional accuracy and mounting accuracy of the ant-proof heat insulating material. Therefore, in order to suppress the generation of gaps as much as possible, killing, phase determination (step-jointing), actual joining, hiring actual joining, buttock granary joining, hiring sickle joining, chase large plug joints, seat ant joints, seats A method of joining ant-prevention heat insulating materials may be adopted by forming an appropriate type of joint such as a sickle joint, a gold ring joint, a buttocks joint, a table-top joint, a sew-on joint, and a sushi joint.

  However, when adhering adjacent ant-prevention insulation materials with an adhesive or the like, before abutting the ant-prevention insulation materials left and right, adhesive or the like is applied to the side end face (small edge surface) of one ant-prevention insulation material in advance. Since it needs to be applied, there is a problem that the construction is complicated. Further, when an ant-proof sealing material containing an ant-proofing agent is used for bonding the ant-proofing insulating materials, there is a problem of volatilization and diffusion of the ant-proofing agent from the ant-proofing sealing material.

  Also, when connecting ant-prevention insulation materials by forming a joint, it is necessary to perform joint processing on the side end surfaces of the ant-prevention insulation materials in advance at the construction site, so the problem is that the construction is complicated is there.

  The present invention has been made in view of the above-described circumstances and problems, and even when a gap occurs in the joints between the termite heat insulating materials adjacent in the lateral direction, termites pass through the gap and the building The joint structure of ant-prevention insulation that can prevent damage to the xylem that is the upper frame of the building, can easily construct the insulation structure of buildings using ant-prevention insulation, and does not require the use of ant-prevention chemicals The purpose is to provide.

It is a joint structure of the ant-proof heat insulating material for outer heat insulation closely arranged so as to be aligned in the direction, and the notch portions are respectively above the ground surface of the building on the side end surface of the ant-proof heat insulating material for outer heat insulation adjacent in the lateral direction. So as to face each other and to penetrate from the outer peripheral surface to the inner peripheral surface of the outer heat insulating ant heat insulating material, and apparently close the joints between the outer heat insulating ant heat insulating materials. A joint-proof ant heat insulating material made of a foam heat insulating material having a density of 90 to 300 kg / m ³ and a compressive strength of 155 to 800 N / cm ² is bonded to the cutout portion with an elastic adhesive.

  The invention according to claim 2 is characterized in that the ant-proof sheet is placed in the notch so that the outer end protrudes outward from the outer peripheral surface of the ant-proof heat insulating material for outer heat insulation and closes at least a part of the joint. Adhering with an elastic adhesive, the ant-proof heat insulating material for blocking joints is bonded with an elastic adhesive through the ant-proof sheet in the notch, and the ant-proof heat insulating material for external heat insulating and the joint blocking The outer end of the ant-proof sheet is embedded in a coating material applied to the outside of the ant-proof heat insulating material.

You can prevent the damage caused by. Moreover, while using the ant-proof heat insulating material which does not receive the damage damage by a termite, the heat insulation of a building can be aimed at, and the heat-insulating structure of the building using a ant-proof heat insulating material can be constructed easily. Furthermore, since there is no need to use an ant-preventing agent, there is no problem of volatilization and diffusion of the ant-preventing agent.

  According to the invention of claim 2, since the outer end of the ant-proof sheet is embedded in the coating material, the adhesive strength between the coating material and the elastic adhesive is small, and the coating material is at the interface with the elastic adhesive.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments, and can be appropriately changed without departing from the gist thereof.

  As shown in FIGS. 1-9, the joint structure of the ant-proof heat insulating material 1 which concerns on 1st Embodiment is the outer peripheral surface 3a and outer peripheral standing part (concrete) of the foundation slab (concrete body) 3 of the solid foundation 2 of the building A. The joint structure of the ant-proof heat-insulating material 1 for outer heat insulation closely adhered to the outer peripheral surface 4a of the body 4 in the circumferential direction, and the side end surface 1c of the ant-proof heat-insulating material 1 adjacent to the lateral heat-insulating material 1 And provided so as to face the notches 6 above the ground surface 5a of the building A and to penetrate from the outer peripheral surface 1a to the inner peripheral surface 1b of the ant-proof heat insulating material 1 for outer heat insulation. The ant-prevention heat insulating material 8 for closing the joints is bonded to the cutout portion 6 with the elastic adhesive 9 so as to close the joints 7 between the ant-proof heat insulating materials 1.

  As shown in FIGS. 1 and 2, the outer peripheral rising portion 4 is erected so as to extend in the circumferential direction at the peripheral portion on the basic slab 3. A leveling mortar 10 is applied on the outer peripheral rising portion 4. In addition, you may construct abandoned concrete or cracked stone under the foundation slab 3.

The ant-proof heat insulating material 1 for external heat insulation is formed in a rectangular plate shape, and is composed of a foam heat insulating material having an apparent density of 90 to 300 kg / m ³ and a compressive strength of 155 to 800 N / cm ² . Therefore, in the ant-proof heat insulating material 1, since the whole foam surface heat insulating material or the surface layer part is hard and it is hard to receive the damage by a termite, it is excellent in ant-proof property. Moreover, since it is excellent in heat insulation performance, it is not necessary to increase the thickness of the foam heat insulating material in order to maintain the energy saving performance of the building A. Therefore, heat insulation performance can be secured with a foam insulation material with a small thickness, and if a foam insulation material with a small thickness is used, the cost is not increased and the exterior design of the building A is not impaired. Furthermore, since non-water absorption is high and durability is excellent, at least a part can be buried in the underground G as shown in FIG.

  The term “ant-proof” as used herein refers to a property that is not easily damaged by termites. Termites are imperfectly metamorphic insects that live closely related to cockroaches, and are the collective term for the termites (Isoptera) Isoptera. This termite has an undeformed rigid head, while having a relatively soft and weak body. Examples of such termites include various types of termites such as Yamato termites and termites. Furthermore, as typified by Yamato termites and termites, termites that inhabit underground cause damage to general insulation materials such as polystyrene-based foam insulation materials that are at least partially embedded in the underground G. It has the characteristic of causing damage to the xylem that is the upper frame of the building A through the inside of the heat insulating material.

Incidentally, the apparent density of the foam insulation is a suitable 90~300kg / m ^3, of which from particularly suitable 100~180kg / m ^3. On the other hand, when the apparent density is less than 90 kg / m ³ , although the foam insulation is not easily damaged by termites, partial damage to the foam insulation is observed, and the reliability of the ant protection effect is observed. There is a tendency to be inferior. On the other hand, when the apparent density exceeds 300 kg / m ³ , the ant-proofing property of the foam heat insulating material can be ensured, but not only the thermal conductivity increases and the heat insulating performance deteriorates, but the weight of the foam heat insulating material increases. Workability tends to deteriorate.

Also, when the compressive strength of the foam insulation is less than 155 N / cm ² , although the foam insulation is not easily damaged by termites, partial damage to the foam insulation is seen, and the ant protection effect Tend to be less reliable. On the other hand, when the compressive strength exceeds 800 N / cm ² , it is not only difficult to obtain a foam molded body typified by an extruded foam and a crosslinked foam, although the ant protection of the foam heat insulating material is ensured. It is difficult to obtain closed cells and a uniform cell structure, and the heat insulation performance tends to be inferior.

  Examples of the foam heat insulating material include synthetic resin-based foams and inorganic foams having a large number of closed cells such as extruded foam plastic, in-mold foam plastic, rigid polyurethane foam, and extruded foam glass.

  Examples of the inorganic base material of the inorganic foam include glass, cement, ceramics, and ceramics. The base inorganic material here refers to an inorganic material that is a main component of the inorganic foam.

  Examples of the compatible synthetic resin include chlorinated vinyl chloride resin, chlorinated polyethylene, and ethylene-vinyl acetate copolymer.

  In addition, although not shown in figure, the foam heat insulating material may coat | cover the surface of the core material which consists of foams, such as a synthetic resin foam which has many closed cells, and an inorganic foam, with the coating material. As described above, the foamed heat insulating material may be hard as a whole, or only the surface layer portion may be hard.

  Moreover, you may add a conventionally well-known appropriate heat stabilizer, a plasticizer, a filler, a pigment, etc. to a foam heat insulating material as needed.

  As shown in FIGS. 1 and 2, the ant-proof heat insulating material 1 is attached so as to be arranged in the circumferential direction on the outer peripheral surface 3 a of the foundation slab 3 of the solid foundation 2 and the outer peripheral surface 4 a of the outer peripheral rising portion 4. ing. Therefore, as shown in FIG. 2, joints 7 are formed so as to extend in the vertical direction at portions where the side end faces 1 c of the ant-proof heat insulating materials 1 adjacent in the horizontal direction are in contact with each other.

How to cast,
And so on. If the ant-proof heat insulating material 1 is brought into close contact with the basic slab 3 or the outer peripheral rising portion 4 by the method [1] or [3], a post-process for bonding the ant-proof heat insulating material 1 with the adhesive as described in [2]. Since it can be omitted, there is an advantage that the workability can be improved.

  As for the method of joining the ant-proof heat insulating materials 1, a butt joint as shown in Fig. 2 is preferable, which does not require joint processing at the construction site. If it is a joint, etc.), it may be adopted. On the other hand, when using the ant-proof heat insulating material 1 that has been jointly processed in the factory in advance, the workability at the construction site does not deteriorate, so killed, phased (joint), actual and hire Adopt various ways of joining, such as buttock, clerk, hijacking, plug, ant, stool, gold ring, butt clamp, pedestal, sword, and sew. Can do.

  If a butt joint that does not require joint processing at the construction site or a joint method that does not deteriorate the workability easily (such as a sewed joint) is used on the side, It is desirable to install the end faces 1c so that the end faces 1c are in close contact with each other so that a gap larger than the maximum linear dimension of the termite head cross section does not occur in the joint 7. In addition, when the clearance gap more than the said maximum linear dimension generate | occur | produces in the joint 7, it may cause the thermal bridge by a heat insulation defect | deletion, or there exists a possibility that what is called noro (slag) of concrete may infiltrate into the clearance gap.

  Since the maximum linear dimension is 1.1 to 1.25 mm for termite ants and 1.0 to 1.2 mm for termite ants, gaps occurring at joints 7 in areas where Yamato termites live Is preferably less than 1.0 mm, preferably less than 0.8 mm, more preferably less than 0.5 mm. Yamato termites do not inhabit, but in areas where termites live, it is desirable that the size of the gap be less than 1.1 mm, preferably less than 0.88 mm, more preferably less than 0.55 mm.

  In order to process the joint 7 between the ant-proof heat insulating materials 1, as shown in FIGS. 3 and 4, first, above the ground surface 5 a of the building A on the side end surface 1 c of the ant-proof heat-insulating material 1 adjacent in the lateral direction. The notch portions 6 are provided so as to face each other and penetrate from the outer peripheral surface 1a of the ant-proof heat insulating material 1 toward the inner peripheral surface 1b.

  As shown in FIG. 3, if the cross-sectional shape of the cutout portion 6 is, for example, a semicircular shape, a circular insertion hole 11 is formed by the two cutout portions 6 facing each other. In this case, if an electric tool (such as an electric horusaw) or a manual tool that can be cut in a circular shape is used, the circular insertion hole 11, that is, the two notch portions 6 having a semicircular cross section are easily formed. It can be formed, and two semi-circular ant-proof heat insulating materials 8 for closing joints can be cut out from the ant-proof heat insulating material 1 for external heat insulation. The cross-sectional shape of the notch 6 may be a semicircular shape, a triangular shape, a rectangular shape, a polygonal shape, or the like. When forming the cutout portion 6 having a cross-sectional shape other than a semicircular shape, various tools such as a manual construction tool represented by a chisel and chisel, and an electric tool represented by an ultrasonic cutter can be used. . In consideration of the processing accuracy, workability, and workability of the joint portion 7, it is desirable to select the electric tool.

  Next, as shown in FIG. 5 to FIG. 8, the joint-proofing ant heat insulating material 8 is bonded in the notch portion 6 with the elastic adhesive 9 so as to close the joint 7 between the ant-proof heat insulating materials 1. In this case, the joint processing is completed.

  As shown in FIG. 5, the ant-proof heat insulating material 8 for closing the joints is formed by adhering flat end surfaces (surfaces that were the side end surfaces 1 c of the ant-proof heat insulating material 1) 8 c together with an elastic adhesive 9. The cylindrical body 12 is further bonded into the notch 6 with the elastic adhesive 9. The elastic adhesive 9 for adhering the cylindrical body 12 in the notch 6 is applied to the notch 6 in advance as shown in FIG. In order to close the joint 7, the surface direction of the end face 8 c of the joint-proof ant heat insulating material 8 intersects the surface direction of the joint 7 at 90 degrees or other angles as shown in FIGS. 7 and 8. Glue so that.

  The elastic adhesive here refers to an adhesive having elasticity even after the joint treatment. In addition, the ant-proof heat insulating material 1 for external heat insulation and the ant-proof heat-insulating material 8 for closing joints have a characteristic of expanding due to a temperature rise or shrinking due to a temperature drop. Therefore, if an adhesive that has high rigidity after joint treatment and has no elasticity is used, it cannot follow the expansion / contraction of the ant-prevention heat insulating material 1 for outer heat insulation or the ant-proof heat insulating material 8 for joint closing, There is a possibility that a new gap is generated due to peeling or cracking of the agent, and termites enter from the gap. Therefore, the elastic adhesive 9 has elasticity that does not cause cracks in itself following the swelling / shrinkage of the ant-proof heat insulating material 1 for external heat insulation and the ant-proof heat insulating material 8 for joint blockage, and the external heat insulating material. What has both the property of the adhesiveness which does not generate | occur | produce with the ant-proof heat insulating material 1 for joints and the ant-proof heat insulating material 8 for joint sealing is suitable.

  Examples of the elastic adhesive 9 include: [1] First polymer [urea resin type, phenol resin type, epoxy resin type, vinyl acetate resin type emulsion type, acrylic type emulsion type, synthetic rubber type (chloroprene rubber type, nitrile rubber type) ), Cyanoacrylate, vinyl acetate resin, ethylene-vinyl acetate copolymer resin, α-olefin resin, aqueous acrylic, etc.] and [2] a second polymer having elasticity (silicone) And a mixture with at least one of a modified silicone type, a polyurethane type, a polysulfide type, a modified polysulfide type, an acrylic type, an acrylic urethane type, an SBR type, and a butyl rubber type).

  Here, if the hardness of the elastic adhesive 9 after the joint treatment is hard enough for the termites to bite, that is, if the shore hardness of the elastic adhesive 9 is 70 or more, the termites are bonded to the joints 7. Even if a gap is generated that can pass through and termites enter the gap from the underground G, the termites can not penetrate by crushing the elastic adhesive 9, so that a barrier effect against termites (invasion prevention effect) is exhibited. There is an advantage. As the elastic adhesive 9 having a Shore hardness of 70 or more, an epoxy elastic adhesive in which an epoxy resin and a modified silicone polymer are mixed is particularly suitable. In addition, if the Shore hardness of the elastic adhesive 9 is less than 70, there exists a possibility that it may invade by being damaged by termites.

  However, even if the shore hardness of the elastic adhesive 9 is less than 70, the distance between each other is less than the maximum linear dimension of the termite head cross section, preferably less than 4/5 of the maximum linear dimension, and more preferably If the aggregate that is resistant to termite secretion and has corrosion resistance to termites is dispersed in the elastic adhesive 9 so that it is less than 1/2 of the maximum linear dimension, termites can pass through the joint 7. Even when a large gap is generated and a termite enters the gap from the ground G, the termite can bite into the elastic adhesive 9 and cannot enter, so there is an advantage that a barrier effect against the termite is exhibited. In this case, if the aggregate is dispersed in the elastic adhesive 9 having a Shore hardness of 70 or more as described above, the double barrier effect due to the hardness of the elastic adhesive 9 itself and the dispersion of the aggregate. (Double penetration prevention effect) is exhibited. In addition, if the space | interval of the said aggregates is more than the said largest linear dimension, there exists a possibility of receiving the damage by a termite and invading.

  In an area where Yamato termites live, the interval between the aggregates should be less than 1.0 mm, preferably less than 0.8 mm, more preferably less than 0.5 mm. Yamato termites do not inhabit, but in areas where termites live, the distance between the aggregates should be less than 1.1 mm, preferably less than 0.88 mm, more preferably less than 0.55 mm.

  The aggregate is not particularly limited, but corrosion-resistant high-hardness particles that are resistant to termite secretions such as formic acid and cannot be broken by termites are suitable.

As high hardness particles,
[1] Ceramic particles [silica sand, glass beads, aluminum oxide (alumina) particles, titanium oxide (titania) particles, etc.]
[2] Synthetic resin particles (acrylic resin particles, polycarbonate particles, polyamide particles, hard vinyl chloride resin particles, etc.),
[3] Metal particles (steel particles, etc.)
Etc. Of these, the cost can be reduced by using inexpensive silica sand as the high hardness particles. The shape of the high hardness particles is not particularly limited, and various shapes such as an indefinite shape, a spherical shape, and a hollow shape can be adopted.

  Further, the clearance between the joint-proofing ant heat insulating material 8 and the notch 6 (maximum filling thickness of the elastic adhesive 9 that bonds the joint-proofing ant heat insulating material 8 into the notch 6) is 0. If it is 3 mm or more and less than the maximum linear dimension of the termite head cross-section, preferably less than 4/5 of the maximum linear dimension, more preferably less than 1/2 of the maximum linear dimension, the ant for blocking joints Even when the heat insulating material 8 can be easily inserted into the cutout portion 6 and a gap through which termites can pass is generated in the joint 7 and termites enter the gap G from the ground G, the termites are used to block the joints. Since it cannot penetrate | invade between the heat insulating material 8 and the notch part 6, there exists an advantage that the barrier effect with respect to a termite is exhibited. In this case, when the Shore hardness of the elastic adhesive 9 is 70 or more, a double barrier effect due to the hardness of the elastic adhesive 9 itself and the narrowness of the clearance is exhibited. Similarly, if the aggregate is dispersed as described above, a double barrier effect due to the dispersion of the aggregate and the narrowness of the clearance is exhibited. Furthermore, if the Shore hardness of the elastic adhesive 9 is 70 or more and the aggregate is dispersed as described above, the hardness of the elastic adhesive 9 itself, the dispersion of the aggregate, and the clearance The triple barrier effect (triple penetration prevention effect) due to the narrowness is exhibited. If the clearance is less than 0.3 mm, it is difficult to insert the ant-proof heat insulating material 8 for closing the joints into the notch 6, while if the clearance is not less than the maximum linear dimension, the elasticity is low in corrosion resistance against termites. When the elastic adhesive 9 is used, termites may pass through the inside of the elastic adhesive 9, and if the elastic adhesive 9 is missing in the first place, it may cause a thermal bridge. is there.

  Therefore, when the clearance is less than 0.3 mm or more than the maximum linear dimension, a separately prepared ant-proof heat-insulating material for closing joints as in the second to fifth embodiments described later is used. It is desirable that the clearance between the joint-proofing ant heat insulating material and the notch 6 is 0.3 mm or more and less than the maximum linear dimension. On the other hand, as described above, the clearance between the joint-proofing ant heat insulating material 8 cut out from the outer heat insulating ant heat insulating material 1 and the notch 6 is 0.3 mm or more and the maximum linear dimension is as described above. If it is less than this, there is no need to separately prepare an ant-proof heat insulating material for closing the joint, and there is an advantage that the cost can be reduced.

  In areas where Yamato termites live, the clearance is preferably 0.3 mm or more and less than 1.0 mm, preferably less than 0.8 mm, more preferably less than 0.5 mm. It is desirable that the clearance be 0.3 mm or more and less than 1.1 mm, preferably less than 0.88 mm, and more preferably less than 0.55 mm, in the area where the termites do not live.

  After the joint 7 has been treated as described above, as shown in FIG. 9, a coating material such as an exterior finisher 13 is provided outside the ant-preventing heat insulating material 1 for outer heat insulation and the ant-proof heat insulating material 8 for closing the joint. Is applied, and the ground is backfilled, and a wooden part is installed on the solid foundation 2 as an upper frame such as the shaft group B and the floor group C. In addition, you may apply | coat undercoat material (coating material) between the ant-proof heat insulating material 1 for outer heat insulation, the ant-proof heat insulating material 8 for joint sealing, and the exterior finishing material 13. FIG.

  If the shore hardness of the coating material is 70 or more after the coating material such as the exterior finishing material 13 or the undercoat material is dried and solidified, there is an advantage that it is difficult to be damaged by termites. In addition, if the Shore hardness of a coating material is less than 70, there exists a possibility of receiving the damage by a termite.

  If the drying shrinkage rate of the coating material is 0.1% or less, there is an advantage that cracks due to drying shrinkage hardly occur. If the drying shrinkage rate of the coating material exceeds 0.1%, cracks due to drying shrinkage may occur.

If the adhesive strength between the coating material and the elastic adhesive 9 is 0.1 N / mm ² or more, there is an advantage that the coating material is difficult to peel off at the interface with the elastic adhesive 9. If the adhesive strength is less than 0.1 N / mm ² , the coating material may peel off at the interface with the elastic adhesive 9, and termites may pass through the gap between the coating material and the elastic adhesive 9. is there.

The coating material that has an adhesive strength of 0.1 N / mm ² or more with the elastic adhesive 9 is not particularly limited, but a cement mortar-based coating material or a polymer cement containing a polymer admixture in cement mortar. A mortar-based coating material is preferred. Examples of the polymer admixture include natural rubber latex, synthetic rubber latex, thermoplastic resin emulsion, thermosetting resin emulsion, bituminous emulsion, mixed dispersion, re-emulsified powder resin, water-soluble polymer, liquid polymer, and the like. .

  In the building A after the foundation outside heat insulation construction as shown in FIG. 9, the termite insulation material 1 for external insulation by termites is damaged, or the inside of the ant insulation material 1 to the tree part of the building A is passed. There is an advantage that it is possible to prevent the invasion of termites and the damage to the xylem caused by the termites. Moreover, since the ant-proof heat insulating material 1 is excellent in durability in addition to the ant-proofing property and has little deterioration, there is an advantage that the heat-insulating performance of the building A can be maintained over a long period of time.

  Further, the ant-proof heat insulating material 8 for closing the joints is located above the ground surface 5a, and the ant-proof heat-insulating material 8 for blocking the joints (part which was a part of the ant-proof heat insulating material 1) has ant-proof properties. is doing. The elastic adhesive 9 has elasticity, and after the joint treatment, the ant-proof heat insulating material 1 for outer heat insulation and the ant-proof heat insulating material 8 for joint filling are expanded by a temperature rise or contracted by a temperature drop. In this case, since the expansion / contraction can be followed, there is no possibility that a new gap is generated due to peeling or cracking of the elastic adhesive 9. Therefore, when a gap occurs in the joint 7, even if a termite enters the gap G from the ground G, a new one due to peeling or cracking of the elastic adhesive 9 inside the joint-preventing heat insulating material 8 for closing the joint is obtained. There is an advantage that termites can be prevented from entering the gap, and the xylem of the building A can be protected from damage caused by termites. Moreover, since it is not necessary to adhere | attach the side end surfaces 1c of the ant-proof heat insulating material 1 adjacent to a horizontal direction beforehand with an adhesive agent etc., the heat insulation structure of the building A using the ant-proof heat insulating material 1 can be constructed easily. There is an advantage. Furthermore, it is not necessary to bond the ant-proof heat insulating materials 1 adjacent to each other in the lateral direction with an ant-proof sealing material containing an ant-proofing agent, and the elastic adhesive 9 also contains no ant-proofing agent. There is an advantage that there is no problem of volatilization and diffusion of the ant-proofing agent.

  Here, the position of the notch 6 can be set as appropriate. For example, it can also be provided at the upper corner (upper corner) of the ant-proof heat insulating material 1 as in the third embodiment described later, or can be set to a height that matches the ease of construction by the installer. . When an adhesive that may cause moisture degradation is employed as the elastic adhesive 9, it is preferable to set it at a position away from the ground surface 5a. Further, from the viewpoint of reducing the length of the ground portion of the gap generated in the joint 7 between the ant-proofing heat insulating materials 1, it can be provided at a position not far from the ground surface 5 a.

  Moreover, in the ant heat insulating material 1, if the thermal conductivity of the foamed heat insulating material is 0.025 to 0.040 W / m · k, the thermal conductivity of the foamed heat insulating material is small, and for example, the heat retention specified in JIS A 9511. Since it corresponds to the 2nd type and 3rd type of plate (extrusion method polystyrene foam), there is an advantage that it is surely excellent in heat insulation performance. In addition, when the thermal conductivity is less than 0.025 W / m · k, the thermal insulation performance is further improved, but the number of closed cells inside the foam insulation is increased, and the resin ratio forming the solid (cell membrane) part. Therefore, the foam insulation is likely to be damaged by termites, and the ant-proof property tends to deteriorate. On the other hand, when the thermal conductivity exceeds 0.040 W / m · k, the heat insulating performance is inferior, and in order to obtain the same heat insulating effect, it is necessary to adopt a foam insulating material having a large thickness or to overlap the foam insulating material. Therefore, the cost tends to be high and the workability tends to deteriorate.

If the water absorption rate of the foamed heat insulating material is 0.1 to 0.4 g / 100 cm ² , the non-water absorption property is high, so that there is an advantage that the durability is surely excellent. In addition, when the water absorption is less than 0.1 g / 100 cm ² , although the durability by non-water absorption is further excellent, the inside of the foam insulation is almost completely closed cell structure, the expansion ratio is lowered and the thermal conductivity Tends to increase and the heat insulation performance tends to deteriorate. On the other hand, when the water absorption rate exceeds 0.4 g / 100 cm ² , the moisture contained in the underground G is absorbed, that is, the durability tends to deteriorate due to the penetration of the moisture into the foam insulation. is there. Moreover, since the water absorption of a foam heat insulating material is influenced by a cross-sectional shape, use of the cut foam heat insulating material cut | disconnected with the slicer etc. is unpreferable. Therefore, use a foam insulation with a skin layer in which the surface of the foam insulation is formed of fine cells, or a foam insulation with the surface of the core made of foam covered with a coating material such as a thermosetting resin. Is preferred.

If the flexural modulus of the foam insulation is 5500-30000 N / cm ² , it has a flexural modulus equal to or higher than that of a general concrete mold plywood, so even when used as a concrete mold There is an advantage that there is no risk of deformation when placing concrete. In addition, when the bending elastic modulus is less than 5500 N / cm ² , if the ant-proof heat insulating material 1 is used as a concrete mold, the ant-proof heat insulating material 1 is deformed or broken at the time of concrete placement, and a desired concrete body can be obtained. There is a risk of not. On the other hand, when the flexural modulus exceeds 30000 N / cm ² , the properties of the flexural modulus can be secured, but the apparent density of the foamed heat insulating material is increased, and the light weight characteristic of the foamed heat insulating material may be impaired.

  Moreover, when using the ant-proof heat insulating material 1 as a formwork for concrete, the through-hole penetrated in the thickness direction is formed in the ant-proof heat insulating material 1 with a drill etc., and formwork space holding materials, such as a separator, in the through-hole However, a pilot hole that extends in the thickness direction but does not pass through the thickness is formed by a drill or the like, and a female screw is formed by tapping around the pilot hole. A male screw formed at the tip of the formwork spacing member is screwed, or the pilot hole is formed in the ant-prevention heat insulating material 1 with a drill or the like, and an anchor plug is fixed to the pilot hole. There is an advantage that a male screw formed at the front end of the formwork space holding member can be screwed into the female screw hole formed in.

  As shown in FIGS. 10 to 12, the joint structure of the ant-proof heat insulating material 1 according to the second embodiment is a joint structure in place of the two ant-proof heat-insulating materials 8 having a semicircular cross section in the first embodiment. A cylindrical ant-proof heat insulating material 28 for closing is bonded in the cutout portion 6 with an elastic adhesive 9.

  The ant-proof heat insulating material 28 for closing joints is made of the same material as the ant-proof heat insulating material 1. The cross-sectional shape of the joint-proofing ant heat-insulating material 28 is matched with the cross-sectional shape of the insertion hole 11 formed by the two notched portions 6 facing each other.

  Here, as in the first embodiment, the clearance between the joint-preventing ant insulating material 28 and the notch 6 (the elastic adhesive 9 for bonding the joint-preventing ant heat-insulating material 28 into the notch 6 is used. The maximum filling thickness) is 0.3 mm or more and less than the maximum linear dimension of the termite head cross section, preferably less than 4/5 of the maximum linear dimension, more preferably less than 1/2 of the maximum linear dimension. For example, the ant-proof heat insulating material 28 for closing the joints can be easily inserted into the cutout portion 6, and even if a gap that allows termites to pass through the joint 7 occurs and termites enter the gap G, Since termites cannot invade between the ant-preventing heat insulating material 28 for closing the joints and the notches 6, there is an advantage that a barrier effect against termites is exhibited. In this case, when the Shore hardness of the elastic adhesive 9 is 70 or more, a double barrier effect due to the hardness of the elastic adhesive 9 itself and the narrowness of the clearance is exhibited. Similarly, if the aggregate is dispersed as described above, a double barrier effect due to the dispersion of the aggregate and the narrowness of the clearance is exhibited. Furthermore, if the Shore hardness of the elastic adhesive 9 is 70 or more and the aggregate is dispersed as described above, the hardness of the elastic adhesive 9 itself, the dispersion of the aggregate, and the clearance The triple barrier effect (triple penetration prevention effect) due to the narrowness is exhibited. If the clearance is less than 0.3 mm, it is difficult to insert the joint-preventing heat-insulating material 28 into the cutout portion 6. On the other hand, if the clearance is greater than the maximum linear dimension, the elasticity is low in corrosion resistance against termites. When the elastic adhesive 9 is used, termites may pass through the inside of the elastic adhesive 9, and if the elastic adhesive 9 is missing in the first place, it may cause a thermal bridge. is there.

  In this case as well, in areas where Yamato termites live, it is desirable that the clearance be 0.3 mm or more and less than 1.0 mm, preferably less than 0.8 mm, more preferably less than 0.5 mm. It is desirable that the clearance be 0.3 mm or more and less than 1.1 mm, preferably less than 0.88 mm, and more preferably less than 0.55 mm, in the area where the termites do not live.

  Also in this embodiment, since the ant-proof heat insulating material 1 for external heat insulation is provided and the joint 7 is closed by the ant-proof heat-insulating material 28 for closing the joint, there is an advantage similar to that of the first embodiment. . Moreover, although it is necessary to prepare separately the ant-proof heat insulating material 28 for joint closure, since it should just be adhere | attached in the notch part 6 as it is, there exists an advantage that an effort is not taken.

  As shown in FIGS. 13 to 15, the joint structure of the ant-proof heat insulating material 1 according to the third embodiment is the ant-proof heat-insulating material 1 in which the notch portion 6 is in close contact with the outside of the solid foundation 2 in the first embodiment. The semi-cylindrical ant heat insulating material 38 for closing the joints is formed in the notch 6 with the elastic adhesive 9 instead of the two ant proof heat insulating materials 8 having a semicircular cross section. It is glued.

  In the present embodiment, as shown in FIG. 13, if the cross-sectional shape of the cutout portion 6 is, for example, a quadrant, an insertion groove 41 having a semicircular cross section is formed by the two cutout portions 6 facing each other. The notch 6 penetrates from the outer peripheral surface 1a to the inner peripheral surface 1b of the ant-proof heat insulating material 1 and opens upward.

  In this case, if an electric tool (such as an electric horusor) capable of semicircular cutting is used, a semicircular insertion groove 41, that is, two opposing cutouts 6 having a semicircular cross section are easily formed. can do. In addition, the cross-sectional shape of the notch 6 may be a triangle, a rectangle, a polygon, or the like in addition to a quarter circle. In order to form the cutout portion 6 having a cross-sectional shape other than a quarter circle, various tools such as a manual building tool such as a chisel and a saw, and an electric building tool such as an electric saw can be used as described above. .

  The ant-proof heat insulating material 38 for closing the joints is made of the same material as the ant-proof heat insulating material 1. The cross-sectional shape of the joint-preventing ant-proof heat insulating material 38 is matched with the cross-sectional shape of the insertion groove 41 formed by the two notch portions 6 facing each other.

  Here, as in the first embodiment, the clearance between the joint-preventing ant heat-insulating material 38 and the notch 6 (the elastic adhesive 9 for adhering the joint-preventing ant-proof heat-insulating material 38 into the notch 6 is used. The maximum filling thickness) is 0.3 mm or more and less than the maximum linear dimension of the termite head cross section, preferably less than 4/5 of the maximum linear dimension, more preferably less than 1/2 of the maximum linear dimension. For example, the ant-preventing heat insulating material 38 for closing the joint can be easily inserted into the cutout portion 6, and even when a gap that allows termites to pass through the joint 7 is generated and termites enter the gap G, Since termites cannot enter between the ant-preventing heat insulating material 38 for closing the joints and the notches 6, there is an advantage that a barrier effect against termites is exhibited. In this case, when the Shore hardness of the elastic adhesive 9 is 70 or more, a double barrier effect due to the hardness of the elastic adhesive 9 itself and the narrowness of the clearance is exhibited. Similarly, if the aggregate is dispersed as described above, a double barrier effect due to the dispersion of the aggregate and the narrowness of the clearance is exhibited. Furthermore, if the Shore hardness of the elastic adhesive 9 is 70 or more and the aggregate is dispersed as described above, the hardness of the elastic adhesive 9 itself, the dispersion of the aggregate, and the clearance The triple barrier effect (triple penetration prevention effect) due to the narrowness is exhibited. If the clearance is less than 0.3 mm, it is difficult to insert the joint-preventing ant heat insulating material 38 into the cutout portion 6. On the other hand, if the clearance is greater than the maximum linear dimension, the elasticity is low in corrosion resistance against termites. When the elastic adhesive 9 is used, termites may pass through the inside of the elastic adhesive 9, and if the elastic adhesive 9 is missing in the first place, it may cause a thermal bridge. is there.

  In this case as well, in areas where Yamato termites live, it is desirable that the clearance be 0.3 mm or more and less than 1.0 mm, preferably less than 0.8 mm, more preferably less than 0.5 mm. It is desirable that the clearance be 0.3 mm or more and less than 1.1 mm, preferably less than 0.88 mm, and more preferably less than 0.55 mm, in the area where the termites do not live.

  Also in this embodiment, since the ant-proof heat insulating material 1 for external heat insulation is provided and the joint 7 is closed by the ant-proof heat-insulating material 38 for closing the joint, there is an advantage similar to that of the first embodiment. . In addition, as in the second embodiment, it is necessary to prepare a joint-preventing heat-insulating material 38 separately for joints, but it is only necessary to bond it directly into the notch 6, so there is an advantage that it does not take time and effort. is there. Further, the notch 6 opens upward, and as shown in FIGS. 14 and 15, the ant-proof heat insulating material 38 for closing the joints can be bonded into the notch 6 from above, so that the construction is easier. There is.

  As shown in FIG.16 and FIG.17, the joint structure of the ant-proof heat insulating material 1 which concerns on 4th Embodiment is the outer end 51a from the outer peripheral surface 1a of the ant-proof heat insulating material 1 for external heat insulation in 2nd Embodiment. The ant-proof sheet 51 is adhered to the notch 6 with the elastic adhesive 9 so as to protrude outward and to close the joint 7 on the upper side of the ant-proof heat insulating materials 1 for external heat insulation. The ant-proof heat insulating material 28 is bonded to the notch 6 with the elastic adhesive 9 through the ant-proof sheet 51, and the outside of the ant-proof heat-insulating material 1 for outer heat insulation and the ant-proof heat-insulating material 28 for closing joints. The outer end 51a of the ant-proof sheet 51 is embedded in the exterior finishing material (coating material) 13 applied to the surface.

  The ant-proof sheet 51 is formed in the notch 6 so that the outer end 51a protrudes outward from the outer peripheral surface 1a of the ant-proof heat insulating material 1 for heat insulation by a predetermined length and closes the joint 7 on the upper side. The elastic adhesive 9 is used for the bonding. The joint-preventing heat-insulating material 28 for bonding the joints is bonded to the cutout portion 6 with the elastic adhesive 9 through the ant-proof sheet 51. The outer end 51 a of the ant-proof sheet 51 is embedded in the exterior finishing material 13 applied to the outside of the ant-proof heat-insulating material 1 for external heat insulation and the ant-proof heat-insulating material 28 for closing joints.

  In addition, when an undercoat material (coating material) is applied between the ant-proof heat insulating material 1 for outer heat insulation and the ant-proof heat insulating material 28 for closing joints, and the exterior finishing material 13, the outer end of the ant-proof sheet 51 51a may be embedded only in the undercoat material, or may be embedded in the exterior finishing material 13 while penetrating the undercoat material. The length of the ant-proof sheet 51 need not be a length that closes the joint 7, that is, a length that the inner end 51 b reaches the inner peripheral surface 1 b of the ant-proof heat insulating material 1 for outer heat insulation. However, it may have a length that protrudes outward from the outer peripheral surface 1a of the ant heat insulating material 1 for external heat insulation by a predetermined length and closes only a part of the joint 7. However, the thickness of the ant-proof sheet 51 is set such that it can be inserted through the elastic adhesive 9 between the ant-proof heat insulating material 28 for closing the joints and the notch 6.

  Here, the termite-proof sheet refers to a sheet that is resistant to termite secretion and has corrosion resistance to termites. As the ant-proof sheet 51, in addition to a glass plate, a metal plate, and a synthetic resin plate each having a Shore hardness of 70 or more, the size (minimum dimension) is less than the maximum linear dimension of the termite head cross section, preferably the maximum linear Punching metal, mesh sheet, etc. having a large number of holes through which termites cannot pass because it is less than 4/5 of the dimension, more preferably less than 1/2 of the maximum linear dimension, and all have a Shore hardness of 70 or more Can be mentioned. Although the material of the ant-proof sheet | seat 51 is not specifically limited, Stainless steel with favorable durability is suitable.

  When the ant-proof sheet 51 has flexibility, the ant-proof sheet 51 is bent in accordance with the shape of the notch 6 at the insertion site at the construction site. On the other hand, if the ant-proof sheet 51 is not flexible, the ant-proof sheet 51 is processed in advance in the factory in accordance with the shape of the notch 6 at the insertion location.

  In the present embodiment, the ant-proof heat insulating material 1 for external heat insulation is provided, and the joint 7 is closed by a separately prepared ant-proof heat-insulating material 28 for closing the joint, so that the same as in the second embodiment. There are advantages. Further, since the outer end 51 a of the ant-proof sheet 51 is embedded in the exterior finishing material 13, the adhesive strength between the exterior finishing material 13 and the elastic adhesive 9 is small, and the exterior finishing material 13 is connected to the elastic adhesive 9. Even if it is a case where it peels at the interface of this, there exists an advantage that it can prevent that a termite penetrate | invades into the joint 7 of the upper side.

  As shown in FIGS. 18 and 19, in the joint structure of the ant-proof heat insulating material 1 according to the fifth embodiment, in the fourth embodiment, the ant-proof sheet 51 is cut out so as to close the joint 7 on the lower side. It is glued inside.

In the present embodiment, the ant-proof heat insulating material 1 for external heat insulation is provided, and the joint 7 is closed by a separately prepared ant-proof heat-insulating material 28 for closing the joint, so that the same as in the second embodiment. There are advantages. Further, since the outer end 51a of the ant-proof sheet 51 is embedded in the exterior finishing material 13, the adhesive strength between the exterior finishing material 13 and the elastic adhesive 9 is 0.1 N / mm ² as in the fourth embodiment. Even if the exterior finishing material 13 is peeled off at the interface with the elastic adhesive 9, the termites pass through the gap between the exterior finishing material 13 and the elastic adhesive 9, and the joint 7 on the upper side. There is an advantage that it is possible to prevent intrusion.

  In addition, you may combine the technique of 1st-5th embodiment suitably as needed. Moreover, in 1st-5th embodiment, the concrete body which makes the ant-proof heat insulating material 1 closely_contact | adhere to an outer peripheral surface is not only the foundation slab 3 and the outer periphery rising part 4 of the solid foundation 2, but the rising part of an outer periphery cloth foundation, one part. It may be a concrete wall of a basement that is exposed to the ground.

  As described above, the joint structure of the ant-proof heat insulating material according to the present invention is such that even when a gap occurs in the joint between the ant-proof heat-insulating materials adjacent in the lateral direction, termites pass through the gap and the wood part of the building. It is suitable for preventing damage to the earth, for easily constructing the heat insulating structure of the building using the ant-proof heat insulating material, and for eliminating the need for ant-proofing chemicals.
