Integrated prefabricated giant column steel formwork supporting system

The invention discloses an integrated prefabricated giant column steel formwork supporting system, and relates to the technical field of giant column steel formwork supporting equipment. According to the technical scheme, the integrated prefabricated giant column steel formwork supporting system comprises a steel formwork hoisted and installed outside vertical steel bars of a structural column, and the steel formwork is installed and reinforced through opposite-pull screw combination; and a main body of each steel formwork is a steel plate, a plurality of vertical keels which are vertically and evenly distributed are welded to each steel plate, a channel steel set is welded to one side of each steel plate to serve as a main keel in the horizontal direction, angle steel used for being connected with the adjacent steel formworks is welded to one side of each steel formwork, and the channel steel sets of every two adjacent steel formworks are fixedly connected through a reinforcing part. The integrated prefabric
