Specifically, the second extension side 203 of the T-shaped structure corresponding to the upper beam 200 among adjacent beams 200 extends downward, and the second extension side 203 of the T-shaped structure corresponding to the lower beam 200 among adjacent beams 200 extends upward, and since the second extension sides 203 of the corresponding T-shaped structures are staggered to form a certain overlapping width, the second bottom side 202 of the T-shaped structure corresponding to the upper beam 200 among adjacent beams 200 can overlap the second extension side 203 of the T-shaped structure corresponding to the lower beam 200. Of course, the cross-section of the column 100 and the beam 200 is not limited to the situation in this embodiment.

The threaded fasteners 5 are, for example, bolts or screws, which can be used with nuts to fasten the first plate 301 to the column The column 100 is locked and fixed, and the second plate 302 and the longitudinal connecting beam 2 are locked and fixed. Of course, through holes corresponding to the through holes and initial positioning notches 303 on the first plate 301 and the second plate 302 should be set on the column 100 and the longitudinal connecting beam 2. When installing the longitudinal connecting beam 2, bolts can be first inserted into the through holes (bolt holes) at the ends of the longitudinal connecting beam 2, and the bolts passing through the longitudinal connecting beam 2 are hung on the initial positioning notches 303 on the second plate 302 connecting the ear plates 300 to form a preliminary fixation.

The floor slab 6 between adjacent assembly unit modules in a plurality of assembly unit modules connected in the vertical direction serves as the floor of the upper assembly unit module and the ceiling of the lower assembly unit module at the same time. There is no need to set up independent floors and ceilings for each layer of assembly unit modules, thereby saving materials. In addition, the floor slab 6 is prefabricated and belongs to a one-way plate according to its force characteristics. The width and length of each floor slab 6 are determined according to a single assembly unit module. The floor slab 6 can be made small in size for easy transportation and on-site lifting.
