The two ends of the transverse keel 8 are respectively fixed on the surface of the two adjacent structural columns 7. A vertical keel 2 is also vertically arranged between the two structural columns 7, which is perpendicular to all the transverse keels 8, and the vertical keel 2 is fixed with each transverse keel 8.

Since the vertical keel 2 is located between the two structural columns 7, the scaffold 1 is fixed through the two structural columns 7 and the vertical keel 2 therebetween, thereby ensuring the stability of the scaffold 1. The vertical keel 2 is multi-sectioned, and the multi-sectioned vertical keels 2 are vertically and sequentially butted to be integrated.

[0028] In combination Figure 3 The column-holding fixing unit 6 and the beam-holding fixing unit 9 each include four fixed steel pipes 14, which are fixed in pairs perpendicularly to form a closed loop, and the structural column 7 or the vertical keel 2 is located in the closed loop structure surrounded by the four fixed steel pipes 14. Two of the four fixed steel pipes 14 extend to one side of the scaffold 1 perpendicularly to the scaffold 1, and after penetrating through the scaffold 1, are fixed with the frame body of the scaffold 1, thereby realizing the fixing of the scaffold 1 with the structural column 7 (or the vertical keel 2).

[0029] Further in combination Figure 4 The bottom fixing unit 5 includes a plurality of cantilever beams 13 arranged side by side, the rear section of the cantilever beam 13 is located on the surface of the lower structural plate 4, and each cantilever beam 13 is fixed on the surface of the lower structural plate 4 by a plurality of fixed bolts 15 arranged along the length direction thereof. The front section of the cantilever beam 13 extends outward from the edge of the lower structural plate 4 to the outside of the lower structural plate 4.

[0030] A fixed beam 10 is further arranged on the upper surface of the section of the cantilever beam 13 located outside the lower structural plate 4, the fixed beam 10 is perpendicular to the cantilever beam 13, and the fixed beam 10 is arranged in multiple and is spaced along the length direction of the cantilever beam 13.

[0033] The specific construction process is as follows:

[0034] As known in the art: Figures 1~3 The structure shown is a schematic diagram after the overall construction is completed. In actual construction on site, the building height of the large space part is high, and the number of layers spanned is large.
