<Reference example>
Next, a reference example of the heat insulating structure of the building will be described with reference to FIGS. 20 and 21.
FIG. 20 is a diagram showing a heat insulating structure of a building erected back to back without separating the first and second wall panels.
That is, in the heat insulating structure of the building 300 shown in FIG. 20, the first building structural material (for example, the first wall panel 10) and the second building structural material (for example, the second wall) are placed on the structural frame of the building 300. The panel 20) is erected, and the first building structural material (first wall panel 10) and the second building structural material (first wall panel 20) are lined in a straight line in a plan view. It is arranged in one wall forming the wall, and is arranged back to back along the thickness direction of the wall without being separated from each other.
Specifically, in the first and second wall panels 10C, 20C, 30C, 40C, the face materials 12C, 22C, 32C, 42C are attached only to one side of the frame bodies 11C, 21C, 31C, 41C. The hollow portion inside is filled with heat insulating materials 13C, 23C, 33C, 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.
As described above, since the first and second wall panels 10C, 20C, 30C, and 40C have a back-to-back structure, the wall thickness of the first and second wall panels as a whole becomes thick and the heat insulating property 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 insulating structure of the building shown in FIG. 20, a plurality of existing building structural materials (wall panels) are used, and the first wall panel 10C and the second wall panel 20C are erected back to back. Therefore, the wall thickness can be easily increased. Therefore, it is possible to reduce the weight at low cost, and to enhance the heat insulating property and the structural strength.
In addition, such a back-to-back structure may be applied to a part of the building which concerns on this invention.

FIG. 21 is an example in which the types of the heat insulating materials filled in the first wall panels 10C and 30C and the second wall panels 20D and 40D are different from each other, and such a back-to-back structure also relates to the present invention. It may be applied to a part of the building.
Specifically, as the heat insulating materials 23D and 43D filled in the second wall panels 20D and 40D arranged on the outside of the building, as described above, the foamed resin-based heat insulating material having high heat insulating performance is used for the building.
