B) As shown in fig. 5, a prefabricated foundation 1, prefabricated wall panel independent foundations 6, 6' and a prefabricated column independent foundation 7 are laid.

C) With reference to fig. 5, 6a, 6b, 10 and 11, the assembled wall system 2 with the floor 8 is hoisted, with the bottom frame 211 placed in the four locator angles 112 on top of the prefabricated foundation 1; specifically, in order to prevent the assembled wall system 2 with the floor 8 from being damaged or deformed during the lifting process, the lifting beams 2124 are installed between the steel columns 212, and as shown in fig. 23, a plurality of screws 2122 are provided on the sealing plate 2121, the lifting beams 2124 are fixedly connected to the top of the steel columns 212 through nuts 2123 and the screws 2122, and after the assembled wall system 2 with the floor 8 is lifted in place, the lifting beams 2124 are required to be detached and the screws 2122 are cut off.

As shown in fig. 2, 5, 8a and 9a, the prefabricated wall panels 4, 4' and the prefabricated column 5 are hoisted, so that the bottom of the prefabricated wall panel 4 is fixedly installed on the independent prefabricated wall panel foundation 6, the bottom of the prefabricated wall panel 4' is fixedly installed on the independent prefabricated wall panel foundation 6', and the bottom of the prefabricated column 5 is fixedly installed on the independent prefabricated column foundation 7.

D) As shown in fig. 8a, 9a, 19 and 22 together, the integral roof board 3 is hoisted, the positioning piece 3012 of the integral roof board 3 is inserted into the inner cavity of the steel column 212, and the steel column 212 and the third embedded steel plate 3011 of the integral roof board 3 are fixedly connected together; meanwhile, the fourth connecting piece 302 on the integral roof board 3 is matched with the convex steel column 42 and the fourth connecting piece 303 is matched with the convex steel column 52, so that the assembly of the roof board can be realized.

In summary, the structural system capable of being assembled quickly and the construction method thereof provided by the embodiment of the invention reduce the workload of on-site wet operation, improve the assembly speed, shorten the construction period and have the characteristics of high construction speed and reliable quality.

While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
