Description

  The present invention relates to a heat insulating structure and a heat insulating method for a unit type building.

In a unit type building formed by combining substantially rectangular parallelepiped frame-like building units, steel members are used as columns and beams constituting the building unit. Building units using steel members are affected by thermal bridges that are unique to steel members in winter. The thermal bridge means a part having extremely large thermal conductivity in the structure, and this part becomes a thermal short-circuit part that can conduct heat more easily than other parts.
Conventionally, as a countermeasure for this thermal bridge, a foamed resin heat insulating material is provided on the indoor side surface of the pillar and the outdoor side surface on the opposite side, and the indoor side surface of the floor beam and ceiling beam (for example, Patent Documents). 1).

JP 2000-136580 A

In the prior art, the heat insulating material is provided on the indoor side surface (upper surface) of the floor beam, but the heat insulating material is not provided on the surface (lower surface) on the opposite side of the building foundation. For this reason, there has been a demand to provide a heat insulating material on the lower surface of the floor beam to further enhance the heat insulating effect.
In addition, since the building unit itself is heavy, it can be considered that a heat insulating material is attached to the lower surface of the floor beam in advance in a factory or the like, thereby saving labor on site. However, since the width of the lower surface of the floor beam is narrow, the area required for attaching the heat insulating material is not sufficient, and there is a concern that the heat insulating material may be easily peeled off.

  An object of the present invention is to provide a heat insulating structure and a heat insulating method for a unit type building that can reliably attach a heat insulating material to the lower surface of a floor beam of a building unit and can enhance a heat insulating effect on the floor.

Therefore, the moisture-proof and heat-insulating sheets 21 and 22 can be interposed between the floor beams 7 and 8 and the foundation. Thereby, since heat can be prevented from being transmitted from the floor beams 7 and 8 side to the foundation, the heat insulation effect on the floor can be enhanced. Moreover, the moisture-proof and heat-insulating sheets 21 and 22 can prevent moisture from entering from the foundation side to the floor beams 7 and 8, so that deterioration of the floor beams 7 and 8 due to moisture can be prevented.
Moreover, since the ant-proof sheet 24 is provided on the entire lower surface of the building unit 1 so as to cover and overlap the moisture-proof and heat-insulating sheets 21 and 22, the ant-proof sheet 24 is provided on the entire lower surface of the building unit 1.
