Description

  The present invention relates to a heat insulating member and a heat insulating method, and more particularly, to a heat insulating member and a heat insulating method for insulating heat between a building and a ground on which the building is constructed.

  In general, in an area where the ground freezes in winter, as shown in FIG. 4, since the ground 15 may be repeatedly subsided by freezing and thawing, there is a possibility that uneven settlement occurs in the building 10. As shown in FIG. 5 and FIG. 6, it is stipulated by the ordinance that the foundation 11 of the building 10 is provided at a position deeper than the freezing depth (the depth of the ground 15 that freezes in winter). It is preventing.

For example, since the freezing depth is set to several tens of centimeters in Honshu and about 1 m in Hokkaido, when constructing the building 10, the ground 15 is dug up to a position deeper than the freezing depth, and the figure is shown in the dug up portion. A fabric foundation 11 as shown in FIG. 5 and a solid foundation 11 as shown in FIG. 6 are constructed, and a building body 12 is constructed on the foundation 11 (see, for example, Patent Document 1).

By bonding to the front and back surfaces of 2 with an adhesive, the heat insulating layer 2 is laminated with a predetermined thickness on the front and back surfaces.

  The heat insulating member 1 includes a sheet-like first heat insulating portion 4 laid on an upper portion of a portion of the ground 15 where the building 10 is constructed (hereinafter referred to as “construction ground 16”), and the first heat insulating portion 4. The sheet-like second heat insulating part 5 hangs downward from the peripheral part. As shown in FIG. 1, the first heat insulating part 4 is laid on the upper part of the construction ground 16.

  The 1st heat insulation part 4 should just have the area more than the bottom face of the building 10, and when the building 10 is constructed in the upper part of the 1st heat insulation part 4, the peripheral part of the 1st heat insulation part 4 is the building 10 What is necessary is just to set an area so that it may correspond with an outer periphery or it is located outside the outer periphery of the building 10. FIG.

  The size of the second heat insulating portion 5 is set based on the freezing depth determined by the ordinance of the area where the building 10 is constructed. Specifically, the first heat insulating portion 4 is laid on the construction ground 16, and the second heat insulating portion 5 is arranged so that the tip of the second heat insulating portion 5 reaches a position deeper than the freezing depth of the ground 15 in this state. The dimensions are set. Here, the depth of freezing is the depth of the ground that freezes in the winter, and the ordinance of the region usually stipulates that the foundation of the building be provided at a position deeper than the freezing depth.

  And by making the front-end | tip of the 2nd heat insulation part 5 reach a position deeper than the freezing depth in this way, the circumference | surroundings of the construction ground 16 can be enclosed by the 2nd heat insulation part 5, and the construction ground 16 and the 2nd heat insulation part 5 and the ground 15 within the freezing depth (hereinafter referred to as “non-construction ground 17”) located outside of 5 can be divided.

Next, an embodiment of the heat insulation method of the present invention will be described.

The temperature of the construction ground 16 is kept substantially the same as the temperature of the portion deeper than the freezing depth of the ground 15.

  Specifically, first, the soil is improved by mixing a hardened material or the like into the portion of the ground 15 where the building 10 is constructed, and the soil improved portion is used as the construction ground 16. The above-described heat insulating member 1 is arranged on the upper portion, the first heat insulating portion 4 of the heat insulating member 1 is laid on the upper portion of the construction ground 16, the second heat insulating portion 5 is suspended downward, and its tip is determined from the freezing depth of the ground 15. The second heat insulating portion 5 surrounds the construction ground 16. Thus, while the 1st heat insulation part 4 is interposed between the building 10 and the construction ground 16, between the construction ground 16 and the non-construction ground 17 of the outer side via the 2nd heat insulation part 5 Divided.

In this way, the building 10 is constructed on the upper part of the construction ground 16, the space between the building 10 and the construction ground 16 is insulated by the first heat insulating portion of the heat insulating member 1, and the construction ground 16 is outside the non-construction ground 17. From the second heat insulating portion 5.

  In the heat insulating member 1 and the heat insulating method according to the present embodiment configured as described above, the first heat insulating portion 4 can insulate between the building 10 and the construction ground 16, and the second heat insulating portion 5 The construction ground 16 and the non-construction ground 17 can be insulated, and the construction ground 16 can be maintained at substantially the same temperature as the temperature of the ground 15 at a position deeper than the freezing depth. Furthermore, it is possible to prevent the heat from the ground surface from being reflected by the reflective layer 3 on the surface of the second heat insulating part 5 and to transmit the heat to the construction ground 16 side, and from the construction ground 16 side by the reflective layer 3 on the back surface. This heat can be reflected to prevent the heat from being transmitted to the non-construction ground 17 side.

  Therefore, in winter, low-temperature heat from the frozen ground 15 can be prevented from entering the construction ground 16 inside the second heat insulating portion 5, and in summer, high-temperature heat from the heated ground 15 is first. 2 It is possible to prevent intrusion into the construction ground 16 inside the heat insulating portion 5, and further, it is possible to prevent the heat of the building 10 of the building 10 subjected to heat storage and cold storage from flowing out to the non-construction ground 17 side. As a result, the air conditioning efficiency can be significantly increased, energy saving can be achieved, and a comfortable living environment can be provided.

  Furthermore, in order to prevent the building 10 from sinking due to the freezing of the ground 15 in winter, it is not necessary to construct the foundation 11 of the building 10 at a position deeper than the freezing depth of the ground 15, so the building 10 is constructed. In this case, it is not necessary to dig up the ground 15 to a position deeper than the freezing depth, and the labor and cost required for the remaining soil processing can be greatly reduced. Furthermore, since it is only necessary to interpose the heat insulating member 1 between the building 10 and the construction ground 16, labor and time required for heat insulation can be reduced, and costs can be reduced. Furthermore, since it is possible to completely insulate between the building 10 and the construction ground 16, moisture from the ground 15 reaches the building 10, and the durability of the building 10 is reduced or mold is generated due to the occurrence of condensation. There is no such thing, and a comfortable living environment can be maintained for a long time.

  In the above description, the reflective layer 3 is provided only on the front and back surfaces of the second heat insulating portion 5. However, the reflective layer 3 may be provided on the front and back surfaces of the first heat insulating portion 4. The same effects can be obtained.
