着力を高めたものであることが好ましい。"Means for Solving the Problem" In order to achieve the above object, the method for constructing the outer wall structure of a building according to the present invention involves arranging a steel plate and a precast concrete plate facing each other, and placing concrete between these plates. The building's exterior walls are constructed by pouring concrete, and the joints between the laterally adjacent exterior walls have embedded reinforcing bars protruding from the side edges of each precast concrete plate, and are slightly spaced apart. The invention is characterized in that after the front and rear surfaces of both outer walls are closed with a closing member, a filler is filled between the two outer walls. In this case, the precast concrete plate is preferably placed outside the steel plate so as to form the outer surface of the outer wall, and it is also preferable that the precast concrete plate has a shea co-star on its inner surface to increase its adhesion to the concrete. preferable.

In addition, since the outer surface of the wall is the concrete surface of the precast concrete board 2,
No maintenance is required to prevent corrosion of this outer surface. Incidentally, when constructing the outer wall of the structure of this embodiment, the temporary columns 7 are erected in advance of the precast concrete plates 2, and the precast concrete plates 2 are erected with the temporary columns 7 supporting them. It is a good idea to keep going.

ユニツト化を促進する上で多大な効果がある。 Since form work can be omitted and factory production can be carried out by making blocks, the on-site man-hours and construction period can be significantly shortened when constructing the outer wall of the steel plate concrete structure. In particular, in the construction of nuclear reactor buildings, it is highly effective in promoting prefabricated buildings and large-scale units.
