[0036] 2. The aluminum plate is divided into 5 pieces of one unit, each piece is 1370mm long, and the total length of one unit is 5500mm. SAP2000 finite element analysis software is used for simulation lifting analysis, and the safety of the unit plate structure itself and the deformation in the lifting process are calculated and analyzed to determine the lifting point. The self-weight load and wind load are applied, the 4-span cantilever 2650mm (the maximum cantilever), 2-span cantilever 2650mm+2-span cantilever 1300mm (eccentric cantilever) unit is analyzed, the keel specification, reinforcement measures and welding requirements are determined, and the unit deformation is ensured within the controllable range in the lifting process. The vertical keel is 80*5 square tube, the cantilever keel is 50*4 square tube and L50*4 angle steel welded.
