Steel structure hoisting device and hoisting method for green building construction

The invention discloses a steel structure hoisting device and hoisting method for green building construction, and belongs to the technical field of steel structure hoisting. According to the steel structure hoisting device for green building construction and the hoisting method, two-point positioning of a steel structure can be achieved through the clamping assemblies on the two sides, the clamping firmness of the steel structure is kept, the potential safety hazard that the steel structure is likely to slip off when being hoisted through a traction rope is avoided, and after clamping, the position of the fixing frame can be adjusted through the threaded transmission assembly; the lifting center point of the steel structure is adjusted, the balance point of the steel structure is conveniently and accurately adjusted, the steel structure is kept in a balanced lifting state, and the safety accident that the center of the steel structure deviates in the lifting process and is prone to falling off is avoided; th
