  As is well known, internal insulation methods for building walls such as reinforced concrete structures such as apartment buildings, steel reinforced concrete structures, and steel ALC (autoclaved light weight concrete) structures are used to bond plywood, asbestos board, gypsum board, etc. to heat insulating materials. The integrated wall panel is bonded and fixed to the wall frame with an adhesive. However, the wall panel has a large weight, and the adhesive panel is displaced from the original crimping position until the adhesive dries and hardens, and the wall panel floats from the housing surface. Meanwhile, there was a problem that the wall panel had to be pressed against the housing surface.

Therefore, as a method for solving the above problems, there is known (1) a method in which a double-sided tape and an adhesive are used in combination, and each is disposed on a part of a wall panel (for example, see Patent Document 1).
