Cantilever I-shaped steel outer frame without steel wire rope and construction method thereof

The steel-wire-rope-free overhanging I-shaped steel outer frame comprises an I-shaped steel frame body, a main body structure floor and a U-shaped anchor ring, a sliding base is slidably connected to the outer wall of the top of the I-shaped steel frame body and fixed to the I-shaped steel frame body through screws, and a fixed half cylinder is welded to the outer wall of the top of the sliding base; a movable half cylinder is movably connected to the outer wall of one side of the fixed half cylinder through a hinge, and protrusions are welded to the inner wall of the movable half cylinder and the inner wall of the fixed half cylinder. The device has the beneficial effects that a steel pipe is placed in a fixed half cylinder, a movable half cylinder is rotated to clamp the steel pipe, a protrusion is inserted into the steel pipe, at the moment, a connecting block is inserted into a first fixing block, a fixing screw is rotated to drive an extrusion block to extrude an insertion block, and the insertion block
