Multiple horizontal rods 111 of the friction support assembly are provided for connecting and fixing the vertical rods 112 of the friction support assembly. The vertical rods 112 of the friction support assembly are located at the corners of the steel frame, are connected into a whole through the horizontal rods 111 of the friction support assembly, and are provided with multiple groups of bolt holes from top to bottom. The scissors rods 113 of the friction support assembly are placed in the middle area, connecting the vertical rods 112 and the horizontal rods 111 of the friction support assembly to form a strengthening area. The short rod 114 is located in the middle area of the middle horizontal rod 111 of the friction support assembly away from the end of the precast member, and is used for fixing the bottom of the jack. The fixing plate 115 is located in the middle area of the middle horizontal rod 111 of the friction support assembly close to the end of the precast member, and is used for fixing the top of the jack.

[0024] The walkway plate 12 is placed on the top surface of the middle horizontal rod 111 of the friction support assembly and is used as a support plane for workers to operate.

[0025] The friction pressure assembly 13 includes a friction assembly 131, a support frame 132, a pressure assembly 133, and a horizontal limit assembly 134. The friction assembly 131 is a rigid plate, and the surface on the side close to the precast member is a rough surface to increase the friction coefficient with the surface of the precast member. The side away from the precast member is fixedly connected to the support frame, and the corners are fixedly connected to the horizontal limit assembly 134. The support frame 132 is formed by welding steel pipes. The side close to the friction assembly 131 is a square frame and is welded and fixed to the friction assembly 131. The side away from the friction assembly 131 is welded and fixed to the telescopic rod of the jack. The pressure assembly 133 is a jack device, and its support on the side close to the precast member is fixedly connected to the support frame 132. The side away from the precast member is welded and fixed to the short rod 114, and is used to push the friction assembly 131 to move horizontally and generate a large contact pressure with the surface of the precast member. The horizontal limit assembly 134 includes a limit rod and a telescopic spring. One end of the limit rod is welded and fixed to the friction assembly, and a circular retaining piece is provided in the middle thereof. The telescopic spring is used to control the overall horizontal sliding of the limit rod.

[0026] The top support assembly 14 includes a top support 141, an adjusting nut 142, and a lead screw 143. The lead screw 143 passes through a circular hole matching the bottom of the vertical rod 112. The two ends of the lead screw 143 are sleeved with the adjusting nut 142. The top support 141 is fixedly connected to the outer end surface of the lead screw 143. The extension length of the lead screw 143 is controlled by the adjusting nut 142 to ensure the overall stability of the prefabricated column safety operation platform that can be assembled.

[0027] The corner connection assembly 2 includes a corner connection group steel frame 21, a corner connection group walkway plate 22 and a lifting lug 23. The corner connection group steel frame 21 is composed of a corner connection group horizontal rod 211, a corner connection group vertical rod 212 and a corner connection group scissor rod 213, and the assembly method of the components is consistent with the installation form of the steel frame 11 of the friction support assembly 1. The lifting lug 23 is set on the top surface of the top corner connection group horizontal rod 211 of the corner connection group steel frame 21 and is welded and fixed.

[0028] After the on-site assembly of a prefabricated column safety operation platform is completed, the operation platform can be lifted to the specified elevation position by the lifting lug 23 provided by the lifting equipment, and the adjusting nut 142 of the top support assembly 14 is adjusted first, so that the extension length of the screw rod 143 can meet the top support 141 to the surface of the prefabricated column, and then the adjusting nut 142 is tightened to limit the movement of the entire top support assembly 14, ensuring that the top support 141 of the safety operation platform can stably contact the surface of the prefabricated column to provide positive support force. Then, the centralized control system 3 is used to control the extension length of the jack, so that the friction assembly 131 is in positive contact with the surface of the prefabricated column, and then the pressure is continuously applied by the jack, so that the friction force generated by the friction surface is sufficient to support 120% of the total load required for the construction work, and then the pressure loading can be stopped, proving that the operation platform has met the conditions for workers to work.

[0029] When a prefabricated column is divided into multiple sections for installation, the prefabricated column safety operation platform can be continuously lifted and used, that is, after the installation of the prefabricated column of this section is completed, the operation platform can be slightly lifted and stabilized by using the lifting lugs 23 provided by the lifting equipment, and the adjusting nut 142 of the jacking assembly 14 is adjusted first, so that the extension length of the screw rod 143 makes the jacking 141 slightly separate from the surface of the prefabricated column, and then the centralized control system 3 is used to control the extension length of the jack, so that the friction assembly 131 is separated from the surface of the prefabricated column by a certain distance. The operation platform is lifted to the specified elevation position, and the adjusting nut 142 of the jacking assembly 14 is adjusted first, so that the extension length of the screw rod 143 can meet the requirement that the jacking 141 reaches the surface of the prefabricated column, and then the adjusting nut 142 is tightened to limit the movement of the entire jacking assembly 14, and ensure that the jacking 141 of the safety operation platform can stably contact with the surface of the prefabricated column to provide positive support force. Then, the centralized control system 3 is used to control the extension length of the jack so that the friction assembly 131 is in positive contact with the surface of the prefabricated column. Then, pressure is continuously applied through the jack so that the friction force generated by the friction surface is sufficient to support 120% of the total load required for the construction work. Only then can the pressure loading be stopped, proving that the operating platform is ready for workers to work.
