【The invention's effect】

As described above, in the present invention, since the panel frame constituting the panel is formed separately on the front and back sides, it is difficult for the bridge to become a heat bridge. Since the wall panel is constructed by connecting the front and back panel connectors that are large and the area of the outside is made small, the transmission of outside air from the front panel facing the outside is small, and the wall panel becomes a cold bridge. It is difficult, and the strength is sufficiently maintained. In addition, since the wall panel is attached to the joint portion via an airtight sheet, a large heat insulating and airtight effect can be obtained. Moreover, the change from the conventional construction method is minimal, and the construction of the partial airtight sheet does not require any special jig, and can be performed freely with scissors and cutters, so the work requires some skill Simple, easy and inexpensive.
