[0071] S2, one end of the first platform plate 4 and the second platform plate 15 is rotatably connected, and the other end is detachably connected, the two platform plates are arranged around the steel pipe concrete column 7, and the steel pipe concrete column 7 is completely wrapped through the locking mechanism, at this time, the memory foam composite material 6 at the end of the mechanical support plate 5 is closely attached to the column.

[0072] S3, at the same time, the platform plate and the top of the support body are fixed through five to six high-strength connecting rods, so that the load is uniformly transmitted to the frame beam 20, and local stress concentration is avoided.

[0073] Working principle: the adjustable operation platform and the use method thereof are cooperated through four core mechanisms of modular assembly, self-adaptive locking, mechanical reinforcement and safety protection, so that the steel pipe concrete column 7 is stably supported and safely constructed, during construction, the platform body 1 is composed of the first platform plate 4 and the second platform plate 15, one end of the two platform plates is hingedly connected, and the other end is connected through the insertion block 8 and the bolt 9, the bolt 9 is loosened, the insertion block 8 is pulled out, the second platform plate 15 is rotated to be away from the first platform plate 4, the platform body 1 is sleeved outside the steel pipe concrete column 7 and placed on the top of the frame beam 20, the second platform plate 15 is pushed to make the rear surface of the second platform plate 15 close to the front surface of the first platform plate 4, the insertion block 8 is inserted and the bolt 9 is tightened, and the preliminary fixing of the platform body 1 is completed, so as to provide a basic frame for subsequent locking and bearing.

[0074] The locking mechanism realizes dynamic locking of the column through linkage transmission and elastic fitting. An operator pulls the pull ring 3 to drive the pull rod 2 to slide in the guide sleeve 14. The pull rod 2 pulls the front end of the ring 10 through the fixing part 21 to move forward, and the ring 10 drives the upper end of the first connecting rod 12 to move. The middle part of the first connecting rod 12 is rotationally connected with the lower end of the second connecting rod 13, thereby pushing the upper end of the second connecting rod 13 to rotate in the slide rail 11, and driving the slider at the lower end of the first connecting rod 12 to slide downward in the slide rail 11, so as to realize synchronous movement of the four groups of support plates 5 to the center of the column. The front end of the four annularly distributed support plates 5 is provided with a memory foam composite material 6. Under the extrusion of the support plate 5, the material automatically fills the concave-convex gap on the surface of the concrete-filled steel tube column 7 to form a ring-shaped locking, thereby ensuring stable connection of the platform with the column and adapting to columns with different diameters.

Such structure of upper and lower wrapping, external support and internal skeleton forms a truss mechanical system, disperses the construction load, and improves the bending resistance and torsion resistance of the platform. At the same time, the platform plate and the top of the support body are fixed through five to six high-strength connecting rods, so as to ensure uniform transmission of the load to the frame beam 20 and avoid local stress concentration.

[0076] The platform realizes double protection through the fireproof cloth 16. The fireproof cloth 16 is sleeved on the concrete-filled steel tube column 7 through the central hole, and is tightly fitted on the surface of the column through the edge elastic tightening belt or the magic tape, and is fixed by pressing the edges of the platform plate. The gap between the platform plate and the column is sealed.

Not only can it provide a stable and safe operation space for the construction of the concrete-filled steel tube column 7, but also can adapt to different construction scenes by adjusting the distance between the platform body 1 and the locking mechanism, and has high practicability and flexibility.
