Large-span continuous beam No.0 block support pre-pressing structure and construction method thereof
The invention discloses a large-span continuous beam No.0 block support pre-pressing structure and a construction method thereof. The support pre-pressing structure comprises a longitudinal beam arranged above a pier at the 0 # block, a supporting column connected to a bridge foundation, a main cross beam assembly connected between the longitudinal beam and the supporting column, a pre-pressing support connected to the upper portion of the longitudinal beam, pre-pressing cross beams arranged at intervals and connected between the pre-pressing support and the longitudinal beam, and a top longitudinal beam connected to the upper portion of the pre-pressing support. The jack is connected between the top longitudinal beam and the top face of the pre-pressing support, and the top pressing assembly and the deformed steel bar assembly are connected to the upper portion of the top longitudinal beam. The pre-pressing support can more accurately describe the uniform distribution stress mode after construction of the No.0 block is completed; the implementation and the adjustment of stress formation are convenient; through combined arrangement of the jack and the like, counter force can be provided for the lower structure, and precise regulation and control can be conducted; and through the arrangement of the supporting columns and the main cross beam assembly, the overall stress in the pre-pressing state can be guaranteed. And local support fine adjustment can be carried out.
本发明公开了一种大跨度连续梁0号块支架预压结构及其施工方法，支架预压结构包含设置于0号块处桥墩上方的纵梁、连接于桥基础上的支撑柱、连接于纵梁与支撑柱之间的主横梁组件、连接于纵梁上方的预压支架、间隔设置且连接于预压支架与纵梁之间的预压横梁、连接于预压支架上方的顶纵梁、连接于顶纵梁与预压支架顶面之间的千斤顶、连接于顶纵梁上方的顶压组件和螺纹钢组件；本发明预压支架可更加准确的描述0号块施工完成后的均布受力方式；且便于实施和进行受力形成的调整；通过千斤顶等联合设置，利于对下部结构提供反力且可进行精确化调控；通过支撑柱和主横梁组件组件的设置，利于保证在预压状态下的整体受力。还可进行局部的支撑微调。
