Suspended formwork structure of high-altitude cantilever steel-reinforced concrete beam

A suspended formwork structure of a high-altitude cantilever steel-reinforced concrete beam comprises a U-shaped screw rod, a bottom formwork and a side formwork. One end of the steel rib is connected with the main body structure, and the other end extends into the precast concrete beam section; the prefabricated concrete beam section is connected with the main body structure through a supporting frame; the U-shaped screws are arranged at intervals in the long axial direction of the steel ribs. The U-shaped screw rod is hung upside down on the steel rib and is connected with the steel rib in a welding manner; horizontal screw rods are arranged on the vertical edges of the two sides of the U-shaped screw rod in the vertical direction at intervals; the inner end of the horizontal screw rod is welded with the U-shaped screw rod; two ends of the bottom of the U-shaped screw exceed the bottom surface of the steel rib; the bottom die is arranged below the steel rib in a full-length mode, and the two sides of the bo
