Continuous beam pier column bracket prepressing device
The invention discloses a continuous beam pier column bracket pre-pressing device, and belongs to the technical field of bridge construction. A suspension is used for providing support, a traction steel bar is used for providing traction, the suspension is suspended above a pier column, the height of the suspension is fixed, then a jack is used for supporting between a lower frame and the suspension, and a pressing disc is arranged at the output end of the jack; the pressing disc makes contact with the bottom sides of the multiple arrayed frame plates to form large-area supporting, the jack can output great pressure, the device serves as a pre-pressing device of brackets on the two sides of the pier column, compared with direct pressing through sand bags and other gravity objects, the device reduces the overall weight and number of the objects to be pressed, the hoisting operation of the objects to be pressed is omitted, and the construction efficiency is improved. The pre-pressing device is of an integrated structure, is directly hoisted above a pier column through a crane, is fixed through a traction steel bar embedded in the top of the pier, and directly applies pressure through a jack, so that the pressure of a bridge on the pier column to a bracket after suspension pouring can be simulated, the device is convenient to mount and dismount, the bracket pre-pressing procedure can be realized as soon as possible, the construction period is shortened, and the efficiency is improved.
本发明公开了一种连续梁墩柱托架预压装置，属于桥梁施工技术领域，通过悬架提供支撑，牵引钢筋提供牵引，将悬架悬置在墩柱上方，使悬架固定高度，再通过千斤顶支撑在下架和悬架之间，千斤顶的输出端设置压盘，压盘与若干排列的架板底侧接触，形成较大面积的支撑，使千斤顶能输出极大的压力，此装置作为墩柱两侧托架的预压装置，相较于通过沙袋等重力物品直接施压，此装置减小了施压物品的整体重量和数量，取消施压物品的吊装作业，此预压装置一体结构，通过吊机直接吊装在墩柱上方，并通过墩顶预埋的牵引钢筋固定，直接通过千斤顶施压，即可模拟出悬浇后墩柱上桥梁对托架的压力，此装置安装拆卸方便，能尽快的实现托架预压工序，减少工期，提升效率。
