Settlement compensation device for bridge and application method
The embodiment of the invention provides a settlement compensation device for a bridge and an application method, the settlement compensation device for the bridge comprises a lower square plate, a threaded rotating disc is arranged on the lower square plate, the threaded rotating disc can rotate around the axis of the threaded rotating disc, the threaded rotating disc is in threaded connection with a threaded fixing disc, and the threaded fixing disc can achieve displacement in the vertical direction through rotation of the threaded rotating disc; the threaded fixing disc is connected with an upper square plate which is connected with the bottom of a support of the bridge. The device can accurately adjust the fulcrum elevation of the bridge superstructure, eliminate the adverse effect of the settlement difference of the abutment on the stress of the bridge superstructure and the support, reduce the material consumption of the bridge superstructure, and improve the stress state of the superstructure, thereby reducing the construction cost of the bridge and prolonging the service life of the bridge; meanwhile, the device can obviously reduce the technical difficulty and the engineering cost of support replacement, avoids the damage of bridge support replacement to a bridge superstructure and a bridge deck system, and is suitable for the technical field of bridge settlement compensation.
本申请实施例提供桥梁用沉降补偿装置及应用方法，包括下方板，下下方板上设有螺纹转动盘，螺纹转动盘可绕其轴线旋转，螺纹转动盘螺纹连接有螺纹固定盘，螺纹固定盘可通过螺纹转动盘的转动实现垂直方向上的位移，螺纹固定盘连接有上方板，上方板与桥梁的支座底部相连。该装置可精确调整桥梁上部结构支点高程，消除墩台沉降差对桥梁上部结构和支座受力的不利影响，减少桥梁上部结构材料用量，改善上部结构的受力状态，从而降低桥梁造价、延长桥梁寿命；同时，该装置还能够显著降低支座更换技术难度和工程费用，避免桥梁支座更换对桥梁上部结构及桥面系的损伤，适用于桥梁沉降补偿技术领域。
