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

C) With reference to fig. 5, 6a, 6b, 10 and 11, the prefabricated wall system 2 with the floor 8 is hoisted with the bottom frame 211 placed in the four positioning 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 hoisting process, a hoisting beam 2124 is installed between the steel columns 212, and the structure is as shown in fig. 23, a plurality of screws 2122 are provided on the cover plate 2121, the hoisting beam 2124 is fixedly connected to the top of the steel column 212 through nuts 2123 and the screws 2122, and after the assembled wall system 2 with the floor 8 is hoisted in place, the hoisting beam 2124 needs to be detached and the screws 2122 are cut off.

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

D) As shown in fig. 8a, 9a, 19 and 22, the integral roof panel 3 is hoisted, so that the positioning piece 3012 of the integral roof panel 3 is inserted into the inner cavity of the steel column 212, and the steel column 212 is fixedly connected with the third pre-buried steel plate 3011 of the integral roof panel 3; meanwhile, the fourth connecting piece 302 on the integral roof panel 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 panel 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.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
