Embodiment Construction
[0025] refer to figure 1 , 2 , 3. The arch rib 1 and the main girder 2 on the side of the steel box on the bridge deck are consolidated horizontally through the chain rod 3, and the main girder on the side of the bridge deck is vertically connected to the arch rib through the rigid suspender 4. The bridge deck is a vertical and horizontal beam structure, In the longitudinal direction, it is the main girder of the steel box side, which is located in the plane of the arch rib, and the suspender adopts a rigid suspender.
[0026] Arch rib 1, bridge deck is steel box side girder 2, chain rod 3, rigid suspender 4 section is steel box section.
[0027] The arch rib 1 and the main girder 2 on the steel box side of the bridge deck are consolidated laterally through the chain rod 3. Since the stiffness of the arch rib is relatively large, while the stiffness of the main girder on the steel box side of the bridge deck is relatively small, the internal force of the main girder on the st...
