Abstract
The utility model discloses a large-span prestress double-arching-frame hoisting structure which comprises an operation platform arranged between two load bearing columns arranged abreast. A lower steel beam is arranged on the operation platform, an upper steel beam is arranged above the lower steel beam, a jack is arranged between the lower steel beam and the upper steel beam, the end portions of arching frames are located under the operation platform between the two load bearing columns, the end portions of the arching frames and the upper steel beam are connected through screws, the top ends of the screws penetrate the upper steel beam to be fastened through nuts, and the bottom ends of the screws penetrate the end portions of the arching frames to be fastened through nuts. The screws are utilized as a hoisting tool, the jack is utilized as a power source to hoist the screws, the screws drag the arching frames to the designed elevation, safety and health of constructors in the arching frame hoisting process are ensured, damage to structure quality caused by the hoisting process is avoided, and meanwhile hoisting time is shortened.
