Within the corridor outline frame, they are evenly distributed according to the construction needs of the corridor. There is an inner hanging basket, and two rows of evenly distributed and symmetrical cantilever beam suspension devices with counterweights are fixed on the roofs at the front and rear sides of the corridor roof. The cantilever beam suspension devices extend out from the front and rear of the corridor roof. The ends of the external cantilever beams on both sides of the rear are connected to suspension wire ropes, and the lower ends of the suspension wire ropes are connected to corresponding external hanging baskets. Support frame suspension devices with cross beams and hangers are evenly distributed on the corridor structural floor. The hangers of the uniformly distributed support frame suspension device are connected to the corresponding inner hanging baskets through connected suspension wire ropes. The support platform set up by crisscrossing horizontal steel pipes and fasteners is connected to the uniformly distributed inner and outer hanging baskets. .

Fixed on the suspension device, one end of the safety wire rope passes through the safety lock, and the other end is fixed on the suspension device. The hanging inner and outer hanging baskets are raised to a certain height below the corridor, and the assembly and installation of the hanging inner and outer hanging baskets are finally completed.

Horizontal frames are set up on the suspended inner and outer hanging baskets, and the hanging baskets are used as stress-bearing structures. The horizontal frames are used to connect the hanging baskets to form an overall operating platform, which facilitates the coordination of construction by multiple operators. Compared with independent operating platforms , the scope of personnel activities is not restricted, and the construction efficiency is high.

The support platform consists of longitudinal horizontal rods, transverse horizontal rods, fasteners and steel scaffolding boards. The horizontal horizontal rods are fixed on the inner and outer suspension baskets using fasteners, and the longitudinal horizontal rods are fixed below the horizontal horizontal rods through fasteners.

The support platform is built using round steel pipes, and the materials can be recycled. When erecting, the distance between the steel pipes can be adjusted according to the horizontal frame erection parameters, making the installation flexible.
