(1) Each vertical pole of the cantilever scaffolding should fall on the cantilever beam. Still, when encountering cast-in-place frame-shear structure, the cantilever beam layout is often not designed, resulting in some vertical poles in the corners or middle parts hanging in the air.
(2) The compression beam length of the cantilever beam is insufficient, especially the cantilever beams at the corners are mostly not handled well.
(3) The ring buckle of the cantilever beam is made of threaded steel.
(4) The scissor brace of the cantilever scaffolding should be considered at a height of more than 20m, that is, it is set continuously along the length and height direction. Most of them do not have horizontal diagonal braces.
(5) In most cantilever scaffolding schemes, wire rope unloading is included in the force calculation. The wire rope cannot be used as a load-bearing rod. Wire rope unloading can only be used as an auxiliary means and should not be included in the force calculation.
(6) The ring buckle connecting the wire rope to the building is made of threaded steel, and the ring buckle is pre-buried horizontally. The number of wire rope lock buckles and the rope head length are insufficient.
(7) The cantilever beam of the cantilever scaffolding is placed on the cantilever component
