The operation of the hoist 40 is stopped when all the wire ropes 30 are in a slack state. And after all the equipment stops operating, disassembling equipment such as shackles, steel cables and the like at the lifting point 22.
Further, after the construction platform is lifted to the working height, the construction method further comprises the following steps: and arranging a fixing unit at the outer side of the construction platform, wherein the fixing unit is used for limiting the horizontal displacement of the construction platform.
