Then, the swivel caster 1 is connected to the vertical support steel pipe 2 (ensuring that the lower end of the vertical support steel pipe 2 is <80mm from the ground). The vertical support steel pipe 2 should preferably be made of ordinary steel pipe. If it is necessary to use the method of butt jointing of steel pipes, it should be done by... The vertical support pipes are fixed with butt couplers 9, which are staggered. The joints of two adjacent vertical supports should not be located within the same synchronous distance. Within the same synchronous distance, the distance between two alternate joints separated by one vertical support pipe 2 in the vertical direction should be >500mm, and the distance from the center of the joint to the main node should be <1 / 3 of the step distance. The longitudinal horizontal support pipe 3 is connected to the vertical support pipe 2 with right-angle couplers 7 (the longitudinal horizontal support pipe 3 is usually located inside the vertical support pipe 2 and is <200mm above the ground, with a step distance <1500mm). The transverse horizontal support pipe 4 is fixed to the lower part of the longitudinal horizontal support pipe 3 with right-angle couplers 7. On the vertical support steel pipe 2 (a horizontal support steel pipe 4 must be arranged at the main node), the longitudinal horizontal support steel pipe 3 serves as the support for the horizontal support steel pipe 4 and is fixed to the inside of the vertical support steel pipe 2 using right-angle fasteners 7; then the oblique horizontal support steel pipe 5 is fixed to the protruding end of the horizontal support steel pipe 4 or the vertical support steel pipe 2 that intersects it using swivel fasteners 8 (the distance from the center line of the swivel fastener 8 to the main node is <150mm), the outrigger steel pipe 6 is fixed to the vertical support steel pipe 2 using swivel fasteners 8, and finally the adjustable top support 10 is temporarily fixed to the top of the vertical support steel pipe 2 using right-angle fasteners 7.

[0016] The protective components include guardrail steel pipes 11, stamped steel scaffold boards 12, wooden toe boards 13, a vertical ladder 16, and a close-mesh safety net 14. The guardrail steel pipes 11 are fixed to the vertical support steel pipes 2 using right-angle couplers 7. The stamped steel scaffold boards 12, wooden toe boards 13, and close-mesh safety net 14 are connected and fixed to the vertical support steel pipes 2, longitudinal horizontal support steel pipes 3, and transverse horizontal support steel pipes 4 respectively using right-angle couplers 7. Precast concrete counterweights 15 are placed on the longitudinal horizontal support steel pipes 3 and transverse horizontal support steel pipes 4 at the bottom layer. The vertical ladder 16 is fixed to the transverse horizontal support steel pipes 4 using right-angle couplers 7. First, the precast concrete counterweights 15 are placed on the longitudinal horizontal support steel pipes within the bottom step distance. On steel pipe 3 and horizontal support steel pipe 4, the bottom step distance guardrail steel pipe 11 on the four sides is fixed to the vertical support steel pipe 2 with right angle couplers 7 (vertical spacing of guardrail steel pipe 11 < 500mm); then the vertical ladder 16 is fixed to the horizontal support steel pipe 4 of the non-cantilever section 18 of the movable operating frame; finally, the guardrail steel pipe 11 of the other step distances except the bottom step distance is fixed to the vertical support steel pipe 2 with right angle couplers 7 (vertical spacing of guardrail steel pipe 11 < 700mm), and the stamped steel scaffold board 12, wooden toe board 13, and dense safety net 14 of the operating layer are connected and fixed to the vertical support steel pipe 2, the longitudinal horizontal support steel pipe 3, and the horizontal horizontal support steel pipe 4 respectively.

[0017] Working principle: The installation site should be flat and firm, ensuring that the ground level deviation is ≤25mm and the load-bearing capacity meets the requirements. The length of the non-cantilever section 18 of the movable operating frame should not be less than 1.25 times the length of the cantilever section 17, and the area of ​​the operating platform should not exceed 10m². 3 The erection height should not exceed 5m;

[0018] When installing the movable operating frame, first mark the positioning lines for the vertical support steel pipes 2 (horizontal and longitudinal spacing of the vertical support steel pipes 2 < 1.3m). Connect the swivel casters 1 to the vertical support steel pipes 2 (ensuring that the lower end of the vertical support steel pipe 2 is < 80mm from the ground; the vertical support steel pipe 2 should preferably be made of ordinary steel pipe; if steel pipes need to be joined by butt joints, they should be fixed with butt joint fasteners 9, and the butt joint fasteners 9 should be staggered. The joints of two adjacent uprights should not be set within the same synchronous distance. Within the same synchronous distance, the distance between two adjacent joints separated by one vertical support steel pipe 2 in the height direction should be > 500mm, and the distance from the center of the joint to the main node should be < 1 / 3 of the step distance). Connect the longitudinal horizontal support steel pipe 3 to the vertical support steel pipe 2 using right-angle fasteners 7 (the longitudinal horizontal support steel pipe 3 is usually set on the vertical support steel pipe 2). The horizontal support steel pipe 4 is fixed to the vertical support steel pipe 2, which is close to the longitudinal horizontal support steel pipe 3, with right-angle couplers 7 (a horizontal support steel pipe 4 must be arranged at the main node). The longitudinal horizontal support steel pipe 3 serves as the support for the horizontal support steel pipe 4 and is fixed to the inside of the vertical support steel pipe 2 with right-angle couplers 7. Then, the oblique horizontal support steel pipe 5 is fixed to the protruding end of the horizontal horizontal support steel pipe 4 or the vertical support steel pipe 2 with swivel couplers 8 (the distance from the center line of the swivel coupler 8 to the main node is <150mm). The outrigger steel pipe 6 is fixed to the vertical support steel pipe 2 with swivel couplers 8. Finally, the adjustable top support 10 is temporarily fixed to the top of the vertical support steel pipe 2 with right-angle couplers 7.

[0019] Then, the precast concrete counterweight 15 is placed on the longitudinal horizontal support steel pipe 3 and the transverse horizontal support steel pipe 4 within the bottom step distance. The guardrail steel pipes 11 on the four sides of the bottom step distance are then fixed to the vertical support steel pipe 2 using right-angle couplers 7 (vertical spacing of guardrail steel pipes 11 < 500 mm). Subsequently, the vertical ladder 16 is fixed to the transverse horizontal support steel pipe 4 of the non-cantilever section 18 of the movable operating frame. Finally, the guardrail steel pipes 11 of the other step distances except the bottom step distance are fixed to the vertical support steel pipe 2 using right-angle couplers 7 (vertical spacing of guardrail steel pipes 11 < 700 mm). The stamped steel scaffolding board 12, wooden toe board 13, and dense safety net 14 of the operating layer are connected and fixed to the vertical support steel pipe 2, the longitudinal horizontal support steel pipe 3, and the transverse horizontal support steel pipe 4, respectively.

[0020] After the movable operating frame is installed, it is moved to the area of ​​the structural slab corresponding to the outer facade of the cantilevered expansion structure to be constructed using casters 1. The adjustable top support 10 is then fixed to the upper structural top slab and structural beam support (the vertical support steel pipe 2, longitudinal horizontal support steel pipe 3, transverse horizontal support steel pipe 4, adjustable top support 10, and structural beam are fixed to the three-sided circumferential support in the structural beam area). After checking that all connection nodes are stable and effective and meet the specifications, workers can then proceed to the operating layer of the movable operating frame for construction.
