  • Mid-span axial force-free connecting device for earth-anchored cable-stayed bridge and method for mounting same
    Patent number: 11753780
    Abstract: The present disclosure discloses a mid-span axial force-free connecting device for an earth-anchored cable-stayed bridge and a method for mounting same. The mid-span axial force-free connecting device for an earth-anchored cable-stayed bridge includes an externally sleeved large steel box girder and an internally embedded small steel box girder. A plurality of bearing beams are arranged on the inner periphery of the externally sleeved large steel box girder. Transverse spherical bearings or vertical spherical bearings are arranged on the bearing beams. The internally embedded small steel box girder is fixedly supported in the externally sleeved large steel box girder through a plurality of transverse spherical bearings and vertical spherical bearings. In the same section, the transverse spherical bearings are symmetrically arranged, and the vertical spherical bearings are also symmetrically arranged.
