Sliding telescopic device for beam end transition of sidewalk ancillary facility
The invention discloses a sliding telescopic device for sidewalk ancillary facility beam end transition, which comprises a main beam end bridge deck slab, a leading beam end bridge deck slab and an ancillary facility transition device arranged at a gap between the main beam end bridge deck slab and the leading beam end bridge deck slab, and the ancillary facility transition device comprises a rotating assembly, a sliding assembly and an ancillary facility bracket, the rotating assembly is arranged on a bridge deck slab at the end of a main beam, one end of the ancillary facility bracket is hinged and fixed with the rotating assembly, and the sliding assembly is fixed with the ancillary facility bracket and erected on a bridge deck slab at the end of a leading bridge. The device can adapt to the situation that the heights of sidewalk step plates of a main bridge and an approach bridge are inconsistent; the device can adapt to large telescopic displacement under the action of beam end live load and temperature and can adapt to the change of beam end corners, and the pin joint structure releases additional stress generated by the device to a main body structure and an accessory structure; and the sidewalk step plate, the sidewalk handrail and the cable trough box support form an integrated structure, integrated manufacturing and installation are facilitated, and interference to a main body structure is small.
本发明公开了一种人行道附属设施梁端过渡的滑动伸缩装置，包括主梁梁端桥面板、引桥梁端桥面板和设置在二者缝隙处的附属设施过渡装置，所述附属设施过渡装置包括转动组件、滑动组件和附属设施托架，所述转动组件设置在主梁梁端桥面板上，所述附属设施托架一端与转动组件铰接固定，所述滑动组件与附属设施托架相固定，滑动组件架设在引桥梁端桥面板上。本发明能适应主桥、引桥人行道步板高度不一致的情形；能适应梁端活载、温度作用下的大伸缩位移，能适应梁端转角的变化，销接构造释放了该装置对主体结构、附属结构产生的附加应力；使人行道步板、人行道栏杆和电缆槽盒支架形成为一体式结构，方便一体化制造、安装，对主体结构干扰小。
