[0044] Please continue reading Figures 1 to 14 In the present invention, the front panel preform 10 includes a first column 11, a first crossbeam 12, and a door column 13. Two first columns 11 are provided, each extending in the vertical direction. The two first columns 11 are arranged side by side in the transverse direction.

Preferably, the front prefabricated part 10, the rear prefabricated part 20 and the connecting member 30 are prefabricated as a whole. In this way, the construction efficiency is further improved.

In this embodiment, only simple welding and assembly are required on site to obtain the connecting member 30 elevator shaft assembly 100, and then multiple elevator shaft assemblies 100 are connected and assembled in sequence from bottom to top to complete the construction of the elevator shaft structure 1. It can be understood that in this embodiment, since most of the components of the elevator shaft structure 1 are prefabricated in the factory, only simple welding and assembly are required during on-site construction, which greatly shortens the construction period. The stable quality of the factory-prefabricated components reduces errors and quality issues during on-site construction, improving the overall construction quality. Moreover, the construction method that combines prefabrication with on-site assembly reduces the manpower and equipment required for on-site construction, thereby reducing construction costs. In addition, the elevator shaft assembly 100 and elevator shaft structure 1 provided by the present invention are particularly suitable for retrofitting elevator shafts in existing buildings without elevators, improving the convenience and efficiency of renovations.

The lower ends of the two bracing rods 231 are respectively fixed to the two ends of the corresponding second crossbeam 22 below the reinforcing braces 23 and are connected to two second columns 21 in a one-to-one correspondence. This further enhances the overall rigidity and stability of the elevator shaft assembly 100.

[0050] Specifically, each group of the reinforcing diagonal braces 23 further includes three stiffening plates 232, one of which is welded to the lower middle portion of the corresponding second crossbeam 22 and screwed to the upper ends of the two diagonal braces 231. The other two stiffening plates 232 are welded to the upper ends of the corresponding second crossbeams 22 and screwed to the lower ends of the two diagonal braces 231.
