Supporting device for large-span steel structure cantilever construction
The invention belongs to the technical field of building construction supporting, and particularly relates to a supporting device for large-span steel structure cantilever construction, which comprises a base, a supporting steel column is fixedly mounted on the end face of the base, a mounting hole is formed in the supporting steel column, and a jack is fixedly mounted in the mounting hole. The output end of the jack is fixedly connected with a supporting seat, the supporting seat is in an inverted frustum shape, the end of the supporting seat is fixedly connected with a top seat, a groove is formed in the end face of the top seat, a movable seat is slidably connected into the groove, and a plurality of magnetic blocks are fixedly embedded into the lower end of the movable seat. Under the condition of ensuring stable supporting of the cantilever beam, the cantilever beam can be pressed down and buffered when stress is uneven, the possibility of supporting failure and stability failure caused by direct uneven stress allocation is reduced, particle impurities and the like can be prevented from influencing the supporting stability, and the structural stability is high.
本发明属于建筑施工支撑技术领域，尤其是涉及一种用于大跨度钢结构悬臂施工的支撑装置，包括底座，所述底座的端面固定安装有支撑钢柱，所述支撑钢柱的内部开设有安装孔，且安装孔的内部固定安装有千斤顶，所述千斤顶的输出端固定连接有支撑座，所述支撑座为倒锥台形设置，所述支撑座的端部固定连接有顶座，所述顶座的端面开设有凹槽，所述凹槽的内部滑动连接有活动座，所述活动座的下端固定嵌入有多个磁块。本发明可以确保对悬臂梁稳定支撑的情况下，可以在受力不均时，对悬臂梁进行下压缓冲，降低直接不均匀的受力分摊导致支撑失效和稳定性失效的可能性，并且可以防止颗粒杂质等影响支撑的稳定性，结构稳定性高。
