Large-span steel truss girder bridge incremental launching construction auxiliary device and method
The invention relates to a large-span steel truss girder bridge incremental launching construction auxiliary device and method, and belongs to the technical field of incremental launching construction. The lifting device comprises a lifting frame, supporting frames and a lifting mechanism, the lifting frame is a hollow cylinder formed by hinging two arc-shaped plates, the bridge pier is sleeved with the lifting frame in a sliding mode, the supporting frames are arranged on the two sides of the lifting frame, and the sections, away from the bridge pier, of the supporting frames incline towards the ground. The supporting frame is used for guiding and supporting a steel truss girder, the lifting mechanism is arranged on the lifting frame and connected with a pier, and the lifting mechanism is used for driving the lifting frame to move on the pier in the vertical direction. The problem that the position angle is prone to deviation in the steel truss girder incremental launching construction process can be solved.
本申请涉及一种大跨径钢桁梁桥顶推施工辅助装置及方法，属于顶推施工技术的领域。其包括升降架、支撑架以及升降机构，所述升降架是由两片弧形板铰接而成的中空筒体，所述升降架滑动套设在桥墩外，所述支撑架在升降架的两侧均有设置，所述支撑架远离桥墩的一段朝向地面倾斜，所述支撑架用于对钢桁梁进行接引支撑，所述升降机构设置在升降架上且与桥墩相接，所述升降机构用于驱动升降架在桥墩上沿竖直方向进行移动。本申请能够改善钢桁梁顶推施工过程中位置角度易存在偏差的问题。
