As an improvement, reinforced steel plates are welded at the connection between the column and the outer frame.

As an improvement, the column is made of a 40×30×3 rectangular tube, and the railing is welded by a 50×30×3 rectangular tube.

Compared with the prior art, the utility model has the following beneficial effects:

1. The overall movable operation platform is adopted to replace the traditional scattered scaffolding, saving a lot of time for installation and disassembly.

2. The frame of the fence is connected and fixed with the top of the formwork by bolts, which has good reliability.

3. The support frame is connected and fixed with the side of the formwork by bolts, which is convenient and quick to operate and has good reliability.
