Japanese Patent Laid-Open No. 9-60140

  When the thickness of the foamed resin heat insulating material is set so as to satisfy the K value of the next-generation energy saving standard in the heat insulating basic construction method, the base thickness composed of the foamed resin heat insulating material and the concrete foundation is increased. For this reason, there is a problem that the foundation protrudes to the outdoor side and protrudes from the outer wall position of the building, thereby deteriorating the appearance of the building.

  In addition, when using concrete screws to fix the foamed resin heat insulating material to the foundation, if the thickness of the foamed resin heat insulating material increases, the workability of the concrete screw deteriorates, and problems such as loosening of the concrete occur.

  In addition, the vacuum insulation material has high heat insulation performance, but since the heat insulation performance can not be demonstrated unless the inside is kept in a vacuum and the vacuum state is maintained, the vacuum insulation material may be damaged during construction, If the vacuum part is broken with a fastener, the heat insulation performance may not be maintained. In addition, even after installation, the surface of the vacuum heat insulating material is easily damaged and the heat insulating performance may not be maintained.

  The above-mentioned problem is a building foundation heat insulation panel attached to the outer periphery of a concrete building foundation, comprising a foamed resin heat insulating material having a groove in the center and a vacuum heat insulating material, and the vacuum heat insulating material is the foamed resin heat insulating material. It is solved by a building foundation thermal insulation panel characterized by being fitted into a groove of the material.

  According to this building foundation thermal insulation panel, a vacuum thermal insulation material having a higher thermal insulation performance value compared to the foamed resin thermal insulation material is used as the thermal insulation material for the building foundation, so that the thermal insulation is high even if the thickness is small compared to the foamed resin thermal insulation material. The performance can be demonstrated.

  In addition, foamed resin insulation is used as a formwork, and vacuum insulation is fitted and integrated into the groove of the foamed resin insulation so that it is not only easy to transport and work, but also fixed to the building foundation. Since it can fix through a foamed resin heat insulating material, it can utilize as a basic heat insulating material, maintaining the performance of a vacuum heat insulating material, without damaging a vacuum heat insulating material. Furthermore, even after the foundation thermal insulation panel is attached, the foam thermal insulation is not damaged and the foundation thermal insulation performance can be maintained for a long time.

  Even if the vacuum heat insulating material is thin, it can exhibit high heat insulating performance, so the thickness of the basic heat insulating material can be reduced, and the workability is good when fixing the basic heat insulating material to the foundation, and the appearance of the building Can look nice.

  Moreover, the said building foundation heat insulation panel WHEREIN: Perforation may be provided in the outer peripheral part of the foamed resin heat insulating material.

  The perforation for fixing the foamed resin insulation material is provided at the outer periphery of the foamed resin insulation material, so that when the foundation insulation panel is attached to the building foundation, it prevents damage to the screws and indicates the fixing position of the screws. Therefore, it is possible to prevent deterioration of the heat insulation performance due to the breakage of the vacuum heat insulating material without accidentally piercing the vacuum heat insulating material fitted into the central heat insulating panel central portion, that is, the groove portion of the foamed resin heat insulating material. it can.

  Furthermore, in the said building basic heat insulation panel, the surface of the foaming resin heat insulating material on the opposite side to the side with the groove part of a foamed resin heat insulating material should just be roughened.

  The surface of the foamed resin insulation material opposite to the grooved side of the foamed resin insulation material, that is, the surface of the foamed resin insulation material on the side opposite to the side where the foundation insulation is in contact with the building foundation is roughened. Adhesion is improved, and when mortar is applied to the foundation surface as a foundation finishing material, adhesion of the mortar to the foundation can be made more reliable and stable.

  In addition, the above-mentioned problem is a building foundation thermal insulation structure in which a building foundation thermal insulation panel is attached to the outer periphery of a concrete building foundation, and the foundation thermal insulation panel is composed of a foamed resin thermal insulation material and a vacuum thermal insulation material having a groove in the center. The vacuum heat insulating material is fitted in the groove portion of the foamed resin heat insulating material, the side having the groove portion of the foamed resin heat insulating material is in contact with the outside of the concrete foundation rising room, and the perforations provided on the outer peripheral portion of the foamed resin heat insulating panel In addition, the foundation thermal insulation panel is fixed to the concrete foundation with a fastener, and the building foundation thermal insulation structure is also solved.

  Since the building foundation thermal insulation panel and the building foundation thermal insulation structure of the present invention are as described above, it is possible to realize a building foundation thermal insulation having a high thermal insulation performance with a thin building foundation thermal insulation structure using a vacuum thermal insulation material.
