Steel structure turnover device and using method thereof

The invention relates to the technical field of steel structures, in particular to a steel structure turnover device and a using method thereof. The problems that the structure is complex, and production and assembly are not convenient are solved. The device comprises a base, the base is provided with an L-shaped top frame, the front end of the top frame is rotatably connected with a rotating seat, the rotating seat is provided with an axially-through mounting port, one side of the mounting port penetrates to the side face, the top frame is radially provided with an insertion port in a penetrating mode, and the insertion port is right opposite to the mounting port. At least two sets of fixing components are slidably connected in the mounting opening in the radial direction, elastic components are arranged between the fixing components and the corresponding side faces of the mounting opening, and the steel structure workpiece compresses the elastic components after being inserted into the mounting opening alon
