Bridge sliding block for bridge incremental launching construction
The invention discloses a bridge sliding block for bridge incremental launching construction, which comprises a base, a jacking structure is mounted in the middle of the upper surface of the base, a deviation rectifying structure and a sliding block assembly are mounted on the jacking structure, a guide beam is placed on the upper surface of the sliding block assembly, and the guide beam is movably connected with the sliding block assembly; by arranging the second jack, the fixed block and the connecting column, when the sliding assembly deviates in the transverse direction, the second jack drives the connecting column to move front and back, the connecting column can drive the fixed block to move front and back, and therefore the first jack can be driven to move front and back, and the first jack can drive the sliding block assembly to move front and back; and the displacement deviation is adjusted in the transverse direction, so that transverse deviation displacement of the main beamin the incremental launching construction process can be prevented, limitation of longitudinal movement of the main beam, damage to a beam body and standard exceeding of deviation between the centerline of the main beam and the designed axis caused by excessive transverse displacement are avoided, and the bridge construction quality is ensured.
本发明公开了一种用于桥梁顶推施工的桥梁滑块，包括底座，所述底座的上表面中部安装有顶升结构，所述顶升结构上安装有纠偏结构和滑块组件，所述滑块组件的上表面摆放有导梁，所述导梁与所述滑块组件活动连接；本发明通过设有第二千斤顶、固定块和连接柱，当滑动组件在横向上发生偏移时，通过第二千斤顶带动连接柱前后运动，连接柱能够带动固定块前后运动，从而能够带动第一千斤顶前后运动，第一千斤顶能够带动滑块组件前后运动，在横向方向上调整位移的偏差，从而能够防止在顶推施工过程中主梁会出现横向偏差位移，避免横向位移过大导致主梁纵移受限和梁体受损以及主梁中心线与设计轴线的偏差超标，确保桥梁施工质量。
