However, even with the structure of the inner wall portion, it is difficult to completely suppress the heat loss from the indoor to the outdoor, but from the viewpoint of energy saving and the like, higher heat insulation performance is required for a house or the like. There is. For example, it is conceivable to thicken the heat insulating material 4 in order to enhance the heat insulating structure of the inner wall portion. However, if the heat insulating material 4 is made thicker, the thickness of the inner wall frame 2 also increases, so that it is necessary to make the housing larger than before. On the other hand, if the inner wall frame 2 has the same thickness as that of the conventional one, the repulsive force of the filled heat insulating material 4 becomes large and bulges on the indoor side, resulting in poor workability. Therefore, there is a need for an inner wall structure that has the same workability and construction cost as the conventional one and has improved heat insulation performance.

It was found that those mainly caused by. In addition, in order to improve the heat insulation performance of the heat insulation inner wall frame, it is possible to maintain the thickness and workability of the heat insulation inner wall frame at the same level as before by using a synthetic resin material with excellent heat insulation performance, and improve the heat insulation performance.

As described above, according to the heat insulating structure of the inner wall portion of the present invention, the inner wall of the building having the frame and the heat insulating inner wall frame arranged in parallel along the frame. In the heat insulating structure of the part, the heat insulating inner wall frame has a synthetic resin heat insulating material layer on the front surface side and an easily deformable heat insulating material layer on the back surface side,
Since the joint heat insulating material is provided between the frame and the frame body of the heat insulating inner wall frame, which is the vertical joint of the heat insulating inner wall frame, the frame and the frame body of the heat insulating inner wall frame are directly connected to each other. The joint and the frame of the heat-insulating inner wall frame do not come into contact with each other and are blocked by the joint heat insulating material having low heat conductivity, and heat loss from indoors to outdoors can be suppressed easily and at low cost. Further, since the synthetic resin heat insulating material is provided on the front surface side of the heat insulating inner wall frame and the easily deformable heat insulating material is provided on the back surface side, the heat insulating performance is improved and the same workability as the conventional one is maintained.

Further, according to the present invention, the easily deformable heat insulating material also covers the back surface of the frame body, and when the heat insulating inner wall frame is attached to the frame assembly, the easily deformable heat insulating material forms the frame assembly. Since it is interposed between the frame body and the frame body, in the inner wall structure using the heat insulating inner wall frame, the easily deformable heat insulating material is deformed according to the shape of the frame,
The easily deformable heat insulating material having low thermal conductivity is interposed between the frame and the frame. Thereby, like the heat insulating structure,
Heat loss from indoors to outdoors on the inner wall can be suppressed easily and at low cost, and since it is not necessary to provide the joint heat insulating material, the construction can be further facilitated.
