AI Technical Summary
Traditional bridge prestressing tensioning requires the use of jacks for installation and removal, which necessitates drilling lifting holes in the beam surface, resulting in damage to the overall structure of the beam and affecting its service life and reliability.
Design a device for installing and removing prestressed tension jacks in a bridge box girder, including a support mechanism, a cantilever mechanism, and a drive mechanism. The bottom end of the support mechanism is fixed to the bottom of the bridge box girder. The cantilever mechanism can adjust the position of the jacks to avoid drilling holes in the beam. The drive mechanism enables stable installation and removal of the jacks.
This improved the reliability of the beam structure, reduced damage to the beam, facilitated the installation and disassembly of the jacks, and enhanced construction efficiency and safety.
