2. Description of the Related Art In recent years, with the widespread use of cooling and heating equipment, various measures have been taken to improve the heat insulation efficiency of walls and roofs of buildings such as houses. For example, it is widely used to provide a heat insulating layer made of glass wool or synthetic resin foam between an exterior material and an interior material of a wall or a roof.

When a heat insulation layer is simply provided between an exterior material and an interior material, moisture generated by condensation is trapped inside and on the surface of the heat insulation layer. Or, the corrosion of the walls and the roof may be accelerated and the life of the building may be shortened.

The middle plate 1
In a 2 × 4 type frame structure in which so-called standardized frame members are joined to each other as materials for columns and beams 104 for connecting and supporting the inner surface of the frame 05, as shown in FIG. May be orthogonal to the middle plate 105 in some cases. In such a case, for example,
Despite the existence of the heat insulating layer 106 between the inner material 05 and the interior material 103, the gap 1 between the mutually joined surfaces of the frame members 109, 109
Water vapor transfer may occur between the intermediate plate 105 and the interior material 103 via the radiator 10. For this reason, during cooling of the room 111, the middle plate 1 is removed from the ventilation space 107 through which the humid outside air flows.
05, the end of the middle plate 105, the gap 110, the interior material 103,
Water vapor moves into the room 111, and conversely, during heating of the room 111, the interior material 103 and the gap 11 are removed from the humid room 111.
There is a problem that water vapor moves to the inner plate 105, the end of the middle plate 105, the end portion of the middle plate 105, and the ventilation space 107 to generate dew on the surface or inside.

Next, the operation of the heat-insulating skeleton structure of the embodiment having the above-described structure will be described. In this heat-insulating skeleton structure, a middle plate 5 is arranged inside the exterior material 3 and the roof material 15 constituting the wall 1 and the roof 2, and a heat-insulating layer 6 made of the same rigid polyurethane foam as described above is provided on the inner surface thereof. By being formed, indoor and outdoor are insulated. In particular,
Since the heat insulating space 9 is formed between the heat insulating layer 6 and the interior material 4 in the wall 1, the heat insulating effect is increased accordingly.

A ventilation space 8 is formed between the air passages and the outside air flows through the ventilation space 8. For this reason, even if the temperature gradient in the heat insulating layer 6 becomes large due to the heating of the room and the dew condensation easily occurs in the heat insulating layer 6 and the middle plate 5, the dew condensation of the outside air flowing through the ventilation space 8 causes the dew condensation. It is prevented beforehand, and if condensation forms, it is quickly removed.

A soft seal member 13 in which a sheet made of a soft urethane foam having a thickness of about 5 mm to 20 mm and impregnated with asphalt is crushed and interposed between the mutually joined surfaces 16b. For this reason, the heat transfer from the room side to the ventilation space 8 side or the heat transfer from the ventilation space 8 side to the room side through the gap between the joint surfaces during the cooling and heating of the room is suppressed, and the heat insulation efficiency is reduced. Is suppressed as much as possible.
