Description

The present invention relates to a thermal insulation structure for buildings.

In recent years, the construction of buildings such as houses has progressed in industrialization. For example, panels are constructed by assembling components such as walls, floors, and roofs in advance and assembling these panels at the construction site. Some methods are used.
Such a wall panel is formed by attaching plywood to both sides of a frame formed by assembling vertical and horizontal frame members into a square frame. Further, a wall panel is disclosed in which a space between a frame and plywood is filled with a heat insulating material in order to improve heat insulating properties (see, for example, Patent Document 1).

Therefore, a heat insulating layer can be formed between the first wall panels 10, 30 and the second wall panels 20, 40, resulting in excellent heat insulation.
Therefore, for example, when providing a heat insulating layer inside a single wall panel, it was necessary to increase the thickness of the wall panel in order to increase the thickness of the heat insulating layer. The thickness of the heat insulation layer can be easily changed by using the two wall panels (1) and adjusting the intervals between the first and second wall panels 10, 20, 30, 40 as appropriate.

<Reference example>
Next, a reference example of a heat insulation structure for a building will be described with reference to FIGS. 20 and 21. FIG.
FIG. 20 is a diagram showing a heat insulating structure of a building in which the first and second wall panels are erected back to back without separation.
That is, the heat insulating structure of the building 300 shown in FIG. A panel 20) is erected, and the first building structural member (first wall panel 10) and the second building structural member (first wall panel 20) are arranged in a straight line in plan view. and are arranged back-to-back along the thickness direction of the wall without being separated from each other.
Specifically, the first and second wall panels 10C, 20C, 30C, and 40C have the face materials 12C, 22C, 32C, and 42C attached only to one side of the frames 11C, 21C, 31C, and 41C. There is, and the internal hollow portion is filled with heat insulating materials 13C, 23C, 33C, and 43C.
The face members 12C, 22C, 32C, and 42C of the wall panels 10C, 20C, 30C, and 40C are erected so as to be back-to-back.
Since the first and second wall panels 10C, 20C, 30C, and 40C have a back-to-back structure in this way, the wall thickness of the first and second wall panels as a whole is thick, and the heat insulation is excellent. Therefore, for example, when a heat insulating layer is provided inside one building structural material (wall panel), it is necessary to increase the thickness of the building structural material (wall panel) in order to increase the thickness of the heat insulating layer. However, in the heat insulation structure of the building shown in FIG. 20, the first wall panel 10C and the second wall panel 20C are erected back to back using a plurality of existing building structural materials (wall panels). Thus, the wall thickness can be easily increased. Therefore, the weight can be reduced at low cost, and the heat insulation and structural strength can be enhanced.
Note that such a back-to-back structure may be applied to a part of the building according to the present invention.
