3) Hoisting the horizontal member to the installation position, arranging the extending end of the plate transverse steel bar (10) of the horizontal member and the U-shaped wall vertical steel bar structure at the top of the second superposed wall in the connecting area (13) in a staggered manner, and building a second supporting system for the horizontal member;
4) Installing a flange die on the outer side of a plate cast-in-situ layer (5) of the horizontal component;
5) Casting a wall cast-in-situ layer (9) of the second superposed wall, a plate cast-in-situ layer (5) of the horizontal member and a connecting area (13) by using concrete;
6) Dismantling a flange mold on the outer side of the plate cast-in-situ layer of the horizontal component;
7) Hoisting the first superposed wall, vertically placing the first superposed wall at an installation position to enable the other end of the vertical connecting steel bar (7) to extend into a reinforcing steel bar hoop in a wall cast-in-situ layer of the first superposed wall, and building a third supporting system for the first superposed wall;
8) And (3) pouring a wall cast-in-situ layer (9) of the first superposed wall by using concrete, so that the wall cast-in-situ layer of the first superposed wall and the second superposed wall which are positioned at the periphery of the connecting area and the plate cast-in-situ layer of the horizontal member form an integrated structure.
