It is necessary to cut and install the basic heat insulating material. Furthermore, it is necessary to pack the base heat insulating material into the gaps between the base heat insulating materials where the bundles 104 are provided by appropriately cutting the base heat insulating material, which causes a problem that the work becomes complicated. Further, when the basic heat insulating material is packed in the gap, it is difficult to match the shape of the gap and the basic heat insulating material, and there is a possibility that a thermal bridge is generated from the portion.

Even if some dimensional error occurs in the material, the easily deformable foam member is deformed so as to absorb the dimensional error, so there is no need to finely adjust the dimensions of the basic heat insulating material, and the work can be performed efficiently. it can. Furthermore, since the basic heat insulating material and the bundle heat insulating material are more closely adhered by the deformation of the easily deformable foam member, there is no gap between them, and a thermal bridge from the location can be prevented.

  Further, the easily deformable foamed member is partially divided into two by a slit formed in the vertical direction from one end side in the longitudinal direction to the bundle hole penetrating the vicinity of the center in the vertical direction. . Thus, when attaching the bundle heat insulating material to the bundle, the easily deformable foam member and the resin sheet are easily deformed, so that one end side of the easily deformable foam member is spread along the slit so that the bundle is bundled in the bundle hole. What is necessary is just to insert and work is easy.

Accordingly, if the bundle is sandwiched from both sides of the bundle, the bundle heat insulating material can be attached to the bundle, and the operation is easy. In addition, since the surface of the resin sheet is formed smoothly, if the base heat insulating material is slid and pushed between the smooth surfaces of the resin sheets of the two bundle heat insulating materials facing each other, the bundle heat insulating material and Frictional resistance generated at the interface with the basic heat insulating material can be reduced, and construction can be performed smoothly.

If it inserts between two bundle heat insulating materials as mentioned above, it is not necessary to cut a basic heat insulating material in a construction site, and it can construct a basic heat insulating material easily.

  Furthermore, when using a bundle made of resin, for example, the outer diameter of the bundle is larger than when using a bundle made of steel. The amount of increases. However, since the easily deformable foamed member is more expensive than the divided heat insulating member, in the case as described above, when creating the bundle heat insulating material, the inside of the resin sheet is created only by the easily deformable foamed member. Instead, it can contribute to the reduction of material cost by making it with the easily deformable foam member and the divided heat insulating member.

  According to the bundle heat insulating material of the third aspect, the notch is formed in the lower corner portion on one end side in the longitudinal direction of the bundle heat insulating material.

Can do.

  The best embodiment of the bundle heat insulating material 1 in this invention is demonstrated below. The bundle heat insulating material 1 which concerns on the 1st Embodiment of this invention is attached to the bundle 3 on the soil 2b adjacent to the standing part 2a of the foundation 2, as shown in FIG. 1, FIG. Then, a slit 5 formed in the vertical direction from the one end side in the longitudinal direction of the substantially rectangular parallelepiped shape made of an easily deformable foam material to the bundle hole 4 provided through the vicinity of the center in the vertical direction is partially A resin sheet 7 having a smooth surface 7a is pasted on both outer side surfaces of the easily deformable foaming member 6 divided into two in parallel with the slits 5.

  As the easily deformable foam member 6, foamed polyethylene or the like that easily elastically deforms can be suitably used, but foamed polyurethane or the like can also be used as appropriate. And as shown in FIG. 1, the easily deformable foaming member 6 is formed in a substantially rectangular parallelepiped shape, and the resin sheet 7 is affixed on the both outer side surfaces, as shown in FIG.

  As the resin sheet 7, a flexible material such as a polyethylene sheet or a polystyrene sheet can be preferably used, so as to match the shape of both outer side surfaces of the easily deformable foamed member 6 formed in a substantially rectangular parallelepiped shape. Appropriately cut and pasted with an adhesive or the like. Further, the surface of the resin sheet 7, that is, as shown in FIG. 11, is formed so that the surface on the side in contact with the two opposing basic heat insulating materials 10 attached to the bundle 3 becomes the smooth surface 7 a. Yes. Moreover, in this embodiment, although the resin sheet 7 is provided so that it may affix on the easily deformable foam member 6, in addition to this, resin itself is coated on the both outer side surfaces of the easily deformable foam member 6. The resin sheets 7 may be provided on both outer sides of the easily deformable foam member 6 by welding or the like.

  As shown in FIGS. 1 and 4, near the center of the easily deformable foam member 6, a bundle hole 4 into which a bundle 3 that is installed on the soil 2 b of the foundation 2 and supports a large pull to which a flooring is attached is inserted. However, the easily deformable foam member 6 is formed so as to penetrate in the vertical direction. Then, from the substantially center of the one end face 6a of the easily deformable foam member 6 to the bundle hole 4 in the longitudinal direction of the bundle heat insulating material 1, the easily deformable foam member 6 communicates in the vertical direction of the bundle hole 4. A slit 5 is formed so as to be partially divided into two. Therefore, when attaching the bundle heat insulating material 1 to the bundle 3, as shown in FIG. 3, the easily deformable foam member 6 and the resin sheets 7 attached to both outer surfaces thereof are easily deformed, so that the slit 5 The one end face 6a of the formed bundle heat insulating material 1 is spread along the slit 5, and the bundle 3 is inserted through the gap.

  Further, by forming the bundle hole 4 to be slightly smaller than the diameter of the bundle 3, the easily deformable foaming member 6 is deformed and closely contacts the outer peripheral surface of the bundle 3, so that a higher heat insulating effect can be exhibited. it can. In this embodiment, the bundle hole 4 is formed in a substantially cylindrical shape so as to penetrate the easily deformable foam member 6 in the vertical direction in the vertical direction of the bundle heat insulating material 1, but the shape of the bundle hole 4 is as follows. It can be appropriately changed according to the shape of the bundle 3.

  Here, when carrying heavy objects such as a piano, in order to reinforce the floor, another bundle (not shown) is provided at a position farther from the rising portion 2a of the foundation 2 than the bundle 3 shown in FIG. Sometimes. In this case, as shown in FIG. 2, a bundle hole 4 is also provided on the other side of the easily deformable foam member 6, and similarly, a slit 5 communicating with the bundle hole 4 is formed on the other end surface of the easily deformable foam member 6. 6b. Thereby, bundle heat insulating material 1 can be attached simultaneously over both bundle 3 and other bundles (not shown).

  Here, as shown in FIG. 5, the inner base heat insulating material 8 is applied to the inner side surface of the rising portion 2a of the foundation 2, and the lower end surface of the inner basic heat insulating material 8 and the soil 2b are pasted by a predetermined interval T1. It has been. The bundle 3 is supported by a base plate 3a, and the base plate 3a is fixed on the soil 2b of the foundation 2 by fixing pins 3b. Therefore, when the bundle heat insulating material 1 is attached to the bundle 3, although the thickness of the base plate 3a and the protrusion of the fixing pin 3b are somewhat absorbed by the easily deformable foam member 6, the rise of the foundation 2 of the bundle heat insulating material 1 There is a possibility that the portion 2a side is slightly lifted. Therefore, as shown in FIG. 1 and FIG. 5, the upper surface of the bundle heat insulating material 1 is a region from the vicinity where the bundle holes 4 are formed to one end portion on the side in contact with the rising portion 2 a of the foundation 2 of the bundle heat insulating material 1. In A1, it is formed so that its height is lower by about 5 mm than other places.

  Moreover, height T2 of area | region B1 other than said area | region A1 of the bundle heat insulating material 1 is formed so that it may become the same as the space | interval T1 of the lower end surface of the inner basic heat insulating material 8, and the soil 2b. Therefore, as shown in FIG. 6, when the inner base heat insulating material 8 is pasted to the inner side surface of the rising portion 2a of the base 2 using an adhesive or the like, the inner base heat insulation is kept until the adhesive dries. By inserting the bundle heat insulating material 1 from the region B side between the material 8 and the soil gap 2b of the foundation 2, the inner basic heat insulating material 8 does not fall downward due to its own weight, and the exact height The inner base heat insulating material 8 can be pasted on.

  As shown in FIGS. 7 and 11, the bundle heat insulating material 1 according to the second embodiment is attached to the bundle 3 on the soil 2 b adjacent to the rising portion 2 a of the foundation 2. And on the outer side surfaces of the two divided heat insulating materials 9 formed so as to be symmetric with respect to a straight line passing through the approximate center of the bundle hole 4 provided penetrating in the vertical direction around the center of the substantially rectangular parallelepiped shape. An easily deformable foam member 6 made of an easily deformable foam material is attached, and a resin sheet 7 having a smooth surface 7 a is further attached to the outer surface of the easily deformable foam member 6.

  As the divided heat insulating material 9, foamed polystyrene or the like similar to the inner basic heat insulating material 8 attached to the rising portion 2 a of the foundation 2 or the basic heat insulating material 10 installed on the soil space 2 b of the foundation 2 is used. And as shown in FIG. 7, it divides | segments into two so that it may become symmetrical with the dividing surface 11 of the division | segmentation heat insulating material 9, and the bundle hole 4 in which the bundle | flux 3 is inserted is formed penetrating the vicinity of a center up and down. Therefore, as shown in FIG. 9, the bundle 3 can be inserted into the bundle hole 4 so as to be sandwiched from both sides of the bundle 3.

  In this embodiment, as shown in FIGS. 9 and 10, the bundle 3 made of resin formed so as to gradually increase in diameter from the substantially center in the vertical direction to the lower end of the bundle 3 is used. A bundle hole 4 is formed in a shape corresponding to 3. That is, as shown in FIGS. 9 and 10, the bundle hole 4 is substantially formed from a lower portion 4 a formed in a substantially rectangular parallelepiped shape so as to cover the base plate 3 a of the bundle 3, and from a substantially central portion of the upper surface of the lower portion 4 a. And an upper portion 4b connected in a columnar shape. Thus, by covering the entire bundle 3 including the base plate 3 a, the bundle heat insulating material 1 does not float even when the bundle heat insulating material 1 is attached to the bundle 3. Of course, the shape of the bundle hole 4 can be appropriately changed according to the shape of the bundle 3 to be used.

  Moreover, also in the bundle heat insulating material 1 of this embodiment, like the bundle heat insulating material 1 which concerns on 1st Embodiment, as shown in FIG. 5, FIG. A region B2 is formed on the other side of the bundle heat insulating material 1 so as to have the same height T2 as the interval T1 to the end surface, and a region A2 formed on the one side about 5 mm lower than the region B2 is formed. Yes. In this embodiment, the region A2 and the region B2 are formed by changing the height of the divided heat insulating material 9. Thereby, even when the base plate 3a protrudes from the bundle hole 4 and one side of the bundle heat insulating material 1 is lifted, it can be inserted between the soil 2b of the foundation 2 and the lower end surface of the inner basic heat insulating material 8. In addition, although the division | segmentation heat insulating material 9 may be integrally molded by the metal mold | die etc., you may form combining several heat insulating materials.

  And the easily deformable foaming member 6 similar to the bundle heat insulating material 1 which concerns on 1st Embodiment, as shown in FIG. 7, of this division | segmentation heat insulating material 9 parallel to the division | segmentation surface 11 into which the division | segmentation heat insulation material 9 was divided | segmented. It is affixed on both outer surfaces with a thickness of about 5 to 20 mm. When the easily deformable foam member 6 is thinner than 5 mm, it is difficult to absorb the dimensional error of the basic heat insulating material 10, and when it is thicker than 20 mm, the easily deformable foam member 6 is often used. So material cost is high. In consideration of this, approximately 10 to 15 mm that can sufficiently absorb the dimensional error of the basic heat insulating material 10 is preferable. And the resin sheet 7 similar to the bundle heat insulating material 1 which concerns on 1st Embodiment is affixed on the both outer side surfaces of the easily deformable foam member 6 in parallel with the division surface 11. FIG.

  Further, an easily deformable foam member 6 may be further provided on a part or all of the inside of the bundle hole 4. That is, as shown in FIG. 8, by providing the easily deformable foaming member 6 inside the upper portion 4b of the bundle hole 4, it can be brought into closer contact with the bundle 3, and high heat insulation can be ensured.

  The one end of the bundle heat insulating material 1 according to the first and second embodiments formed as described above on the side in contact with the rising portion 2a of the foundation 2 is shown in FIGS. Thus, in order to ensure the space X for providing the termite-proofing agent 12 in the vicinity of the boundary between the soil gap 2b and the rising portion 2a of the foundation 2, the lower corner portion on one end side in the longitudinal direction of the bundle heat insulating material 1 is notched. A notch 13 is formed so as to be bent. The space X is formed so as to be surrounded by the notch 13, the rising 2 a of the foundation 2, and the soil 2 b of the foundation 2.

  It shows below about the basic heat insulation structure 14 using the bundle heat insulating material 1 formed as mentioned above, and its construction method.

  As shown in FIG. 5, the basic heat insulating structure 14 according to the present embodiment has an inner basic heat insulating material 8 attached to the inner surface of the rising portion 2 a of the foundation 2 from the soil 2 b of the foundation 2 to a predetermined height, One end portion is inserted between the plurality of bundles 3 installed on the soil space 2b adjacent to the rising portion 2a of the foundation 2, and between the soil space 2b of the foundation 2 and the lower end surface of the inner foundation heat insulating material 8. , The bundle heat insulating material 1 inserted into the bundle hole 4 and attached to the bundle 3 and, as shown in FIG. 11, installed on the soil 2b between the two bundle heat insulating materials 1 facing each other. And a basic heat insulating material 10. Further, in the lower corner of one end portion of the base heat insulating material 10 inserted between the soil gap 2b of the foundation 2 and the lower end surface of the inner base heat insulating material 8, a cutout is formed in the same manner as the cutout portion 13 of the bundle heat insulating material 1. A portion 15 is formed, and in a space X formed by being surrounded by the rising portion 2a of the foundation 2 and the soil gap 2b of the foundation 2, it extends over the vicinity of the boundary between the soil gap 2b of the foundation 2 and the rising portion 2a. An anti-anticide 12 is provided.

  When constructing the foundation heat insulating structure 14, the inner base heat insulating material 8 is attached to the inner surface of the rising portion 2 a of the foundation 2 from the soil 2 b of the foundation 2 to a predetermined height with an adhesive or the like. In this case, as shown in FIG. 5 described above, the bundle heat insulating material 1 can be used as a spacer. And the bundle heat insulating material 1 is attached to the bundle 3 so that the rising part 2a of the foundation 2 may be contact | connected. In this case, when using the bundle heat insulating material 1 according to the first embodiment, as shown in FIG. 3, one end surface 6 a of the easily deformable foam member 6 is expanded along the slit 5 and bundled in the bundle hole 4. When the bundle heat insulating material 1 is attached to the bundle 3 so as to insert 3 and the bundle heat insulating material 1 according to the second embodiment is used, the bundle heat insulating material divided into two as shown in FIG. 1 is attached to the bundle 3 so as to be sandwiched from both sides.

  And as shown in FIG. 11, the base heat insulating material 10 is inserted between the two bundle heat insulating materials 1 which oppose each other. At this time, both end surfaces 10a of the basic heat insulating material 10 and the smooth surfaces 7a of the resin sheets 7 of the two opposite bundle heat insulating materials 1 are in contact with each other, and the basic heat insulating material 10 is placed between the smooth surfaces 10a. It is inserted so as to push in while sliding. Thereby, since the frictional resistance of the interface between the basic heat insulating material 10 and the bundle heat insulating material 1 is reduced, the basic heat insulating material 10 can be easily inserted. Moreover, since the base heat insulating material 10 is inserted while the easily deformable foam member 6 is deformed, the dimensional error of the base heat insulating material 10 can be absorbed, and the bundle heat insulating material 1 and the base heat insulating material 10 are more closely adhered to each other. Thermal insulation can be demonstrated.

  The basic heat insulating structure 14 as described above is an example, and a well-known configuration other than the one shown in the present embodiment can be added as necessary, and the construction method is also an example. Of course, it is possible to add a procedure for constructing a well-known configuration between and before and after.

  Further, after the completion of the house, for example, after about 10 years have passed, the inner base heat insulating material 8 may be removed and then the rising portion 2a of the foundation 2 may be inspected. In this case, since a large pull (not shown) is supported on the upper part of the bundle 3, it is difficult to remove the inner base heat insulating material 8. However, as shown in FIG. 12, the inner base heat insulating material 8 of the present embodiment is provided with a slit S1 having a width of about 2 to 5 mm in the horizontal direction on the inner side surface of the building. Oppositely, a slit S2 having a width of about 2 to 5 mm is preliminarily provided in the horizontal direction on the outer surface of the building. And when slit S1 and S2 are affixed on the standing | starting-up part 2a of the foundation 2, it is preferable to have provided below the lower surface of the large pull. Thereby, if the inner base heat insulating material 8 is cut with a cutter or the like so as to communicate from the slit S1 on the inner surface of the building to the slit S2 on the outer surface of the building, the upper portion 8a and the lower portion 8b can be divided. By removing only 8b, the rising portion 2a of the foundation 2 can be easily inspected. And if inspection is complete | finished, the lower part 8b should just be inserted in the original position again.

  Generally, since the inner base heat insulating material 8 is formed to a thickness of about 65 to 105 mm, it is difficult to cut the inner basic heat insulating material 8 with a tool such as a cutter. By providing S1 and S2 in advance, the inner basic heat insulating material 8 can be easily cut, and also serves as a mark for cutting. In this embodiment, the inner base heat insulating material 8 having a thickness of 85 mm is used. In this case, the depth of the slit S1 is about 40 to 50 mm, and the depth of the slit S2 is about 3 to 8 mm. It is preferable to provide it in consideration of the handling of the inner basic heat insulating material 8 and the case of cutting it. That is, the thickness of the inner heat insulating material 8 at the location where the slits S1 and S2 are provided is preferably about 27 to 42 mm. If it is thicker than this, it will be difficult to cut with a cutter or the like. In particular, there is a possibility that the slits S1 and S2 may break. In addition, in this embodiment, as shown in FIG. 12, the slit S2 on the outer side of the building is formed shallower than the slit S1 on the inner side of the building. However, the slit S1 on the inner surface of the building may be shallower.

  Furthermore, although the horizontal width of the inner base heat insulating material 8 is usually 1000 mm, as shown in FIG. 12, there is no gap in the rising portion 2a of the base 2 on the front surface of the place where the bundle 3 is provided. When the boundary K of the attached inner base heat insulating material 8 is brought, the work of removing the inner basic heat insulating material 8 can be easily performed at the time of inspection of the rising portion 2a of the base 2. Moreover, in the above-mentioned location, even if there is a bundle 3 in the front by making the width of the inner basic heat insulating material 8 narrower than usual, for example, about 500 mm, the inner basic heat insulating material 8 is Since a small turn is required when removing, the work can be easily performed.

  The bundle heat insulating material 1 according to the present invention can be used for bundles 3 of various shapes including bundles 3 made of steel, wood, resin, and the like.
