Fabricated construction method for parking and charging intensive assembly of multilayer steel frame structure

The invention discloses a fabricated construction method for a parking and charging intensive assembly of a multilayer steel frame structure. Firstly, a subgrade and foundation are constructed, a steel frame supporting fabricated structure is subjected to detailed design and factory machining and is transported to a construction site, an underground first-floor solid belly type rectangular steel column is firstly hoisted, and an underground first-floor common ordinary reinforced concrete floor and a concrete beam are constructed; first-layer box type steel columns are hoisted; first-layer steel beams are hoisted; first-layer steel bar truss floor support plates are mounted; construction is sequentially carried out to the eighth floor, and construction of the parking and charging intensiveassembly of the multilayer steel frame structure is completed. According to the fabricated construction method for the parking and charging intensive assembly of the multilayer steel frame structure,reasonable vent holes are
