step four: the method comprises the steps that a foundation beam (2) and an independent foundation (3) are cast on a foundation cushion (4) in situ, in the casting process, a concave groove is preset on the upper surface of the foundation beam (2), an L-shaped groove (9) is preset on the independent foundation, and steel plates (10) are pre-buried on each side vertical surface of the L-shaped groove (9);
step five: placing the prefabricated assembled composite wallboard (1) in the second step into a concave groove, meanwhile, placing a reinforcement cage at the lower part of the prefabricated L-shaped constructional column (5) in the third step into an L-shaped groove (9), and after the positions of the prefabricated assembled composite wallboard (1) and the L-shaped constructional column (5) are adjusted, fixedly connecting the assembled composite wallboard (1) with the foundation beam (2);
Step six: a formwork is erected, and the connecting position of the L-shaped constructional column (5) and the independent foundation (3) is poured, namely concrete is poured into the poured L-shaped groove (9) and maintained, so that the L-shaped constructional column (5) and the independent foundation (3) are connected into a whole;
step seven: and after the concrete at the connecting position of the L-shaped constructional column (5) and the independent foundation (3) reaches the curing target, installing a layer of wall.
