Layer-by-layer accumulation synchronous lifting construction method for wavy special-shaped steel structure awning

The invention discloses a layer-by-layer accumulation synchronous lifting construction method for a wavy special-shaped steel structure awning. According to structural analysis, the floors of the three-layer structure, the four-layer structure and the five-layer structure are provided with large-area floors which can be used as steel structure assembling sites, the floors are lifted upwards layer by layer to complete steel structure welding, and the lifting height of the steel structure can be reduced from 36.62 m to 14.4 m by adopting the scheme. Main work such as splicing, welding and painting of the steel structure is carried out on the floor, and the aloft work amount is reduced to the minimum. The hydraulic synchronous lifting equipment is small in facility size and weight, high in maneuverability and convenient to mount and dismount; temporary facilities such as lifting supports and platforms utilize existing structures such as steel supporting stand columns, the use amount of the temporary facilities i
