The invention belongs to the technical field of overall jacking of large-span special-shaped grid structures, and particularly relates to an overall jacking device and method for a large-span special-shaped grid structure. The jacking device comprises a jacking unit; each jacking unit comprises a supporting ball joint, a conversion supporting rod, a jacking mechanism, a stand column and an anchoring box, the supporting ball joints are located over the centroid of a jacking point grid of the special-shaped grid structure, the supporting ball joints are connected with rod piece joints of the jacking point grid through the conversion supporting rods, and the jacking mechanisms are located under the supporting ball joints; the stand columns are erected at the tops of the supporting ball joints, the anchoring boxes are fixed to the tops of the stand columns, stay cables are connected between the anchoring boxes and rod piece joints outside the jacking point grids, and the anchoring boxes are mutually tied through horizontal stay cables. The large-span special-shaped grid structure jacking device is suitable for the large-span special-shaped grid structure jacking working condition, in the jacking process, the large-span special-shaped grid structure is evenly stressed, and it is guaranteed that the whole large-span special-shaped grid structure is safely in place.
本发明属于大跨度异形网格结构整体顶升技术领域,具体涉及一种大跨度异形网格结构整体顶升装置及顶升方法;顶升装置包括顶升单元;每个顶升单元包括支撑球节点、转换撑杆、顶升机构、立柱以及锚拉箱,支撑球节点位于异形网格结构的顶升点网格的形心处正上方,支撑球节点与顶升点网格的杆件节点之间通过转换撑杆连接,顶升机构位于支撑球节点的正下方;立柱竖立在支撑球节点的顶部,锚拉箱固定在立柱的顶部,锚拉箱与顶升点网格以外的杆件节点之间连接斜拉索,锚拉箱之间通过水平拉索相互拉结;本发明适用于大跨度异形网格结构顶升工况,顶升过程中,大跨度异形网格结构受力均匀,保证大跨度异形网格结构整体安全就位。
