Dismantling device suitable for pier top swivel spherical hinge and construction method of dismantling device
The invention provides a pier top swivel spherical hinge dismantling device and a construction method thereof.The pier top swivel spherical hinge dismantling device comprises a spherical hinge arranged between a pier column and a beam body and further comprises a vertical jacking mechanism and a spherical hinge dismantling mechanism, and the vertical jacking mechanism is arranged between a bearing platform and the beam body and used for jacking the beam body; the spherical hinge dismantling mechanism comprises a horizontal slide way arranged on one side of the pier column and a counter-force frame arranged on the other side of the pier column, and a counter-force pushing piece is arranged on the counter-force frame and used for pushing the spherical hinge into the horizontal slide way. The spherical hinge dismantling mechanism is adopted, the spherical hinge can be transversely moved, the dismantling speed of the spherical hinge is increased, turnover materials are saved, and the closure construction period of the pier top continuous beam body is shortened; the whole beam body is jacked through the vertical jacking mechanism, jacking does not exceed 1 cm, it is fully guaranteed that the stress condition of the beam body basically does not change, two mechanical structure models of a spherical hinge dismantling structure and the stress state of the beam body during jacking are established, stability and safety are guaranteed, and the construction period is shortened.
本发明提出了一种适用于墩顶转体球铰拆除装置及其施工方法，包括设置在墩柱与梁体之间的球铰，还包括竖向顶升机构和球铰拆除机构，竖向顶升机构设置在承台与梁体之间用于顶升梁体；球铰拆除机构包括设置在墩柱一侧的水平滑道和设置在墩柱另一侧的反力架，反力架上设有反力推动件用于将球铰推入水平滑道。本发明采用球铰拆除机构，该发明能够横向移动球铰，加快了球铰的拆除速度和节约了周转材料，缩短了墩顶连续梁体合拢施工周期；本发明通过竖向顶升机构对整个梁体进行顶升，顶升不超过1cm,充分保证梁体应力状况基本不发生变化，且建立了球铰拆除结构和顶升时梁体应力状态两种力学结构模型，不仅保证了稳定性和安全，还缩短了工期。
