Back-jacking deviation correction construction method for cast-in-place floor slab in initial deviation state
The invention discloses a back-jacking deviation-rectifying construction method for a cast-in-place floor slab in an initial deviation state, which comprises the following steps of: adopting a disc buckle type independent tower as a lower temporary supporting operation frame and a counter-force acting frame below a back-jacking jack, and sequentially carrying out vertical back-jacking on the bottom of the slab through the jack at the top of a vertical rod of the disc buckle type tower; and after each jacking operation construction is completed, the adjustable jacking supports at the tops of the other towers are sequentially subjected to jacking treatment until the downwarping value of the bottom of the floor meets the standard requirement. By means of the method, the cast-in-place floor in the initial deviation state can be subjected to back-jacking deviation correction, it is guaranteed that no large crack is generated on the floor face in the back-jacking process through process control, the safety and reliability of the construction process are guaranteed, operability is high, construction operation cost is low, construction efficiency is high, and the method can be widely applied and popularized to implementation of such projects.
本发明公开了一种针对初始偏位状态下现浇楼板的回顶纠偏施工方法，该方法在于采用盘扣式独立塔架作为下部临时支撑作业架及回顶千斤顶下方反力作用架，通过盘扣式塔架立杆顶部的千斤顶依次对板底进行竖向回顶，每次回顶作业施工完成后其他各塔架顶部可调顶托依次进行顶紧处理，直至楼板底部下挠值满足规范要求。采本方法可针对初始偏位状态下现浇楼板进行回顶纠偏，采用过程控制确保回顶过程中板面不会产生较大裂缝，确保施工过程的安全可靠性，可操作性强，施工作业成本低，施工效率高，可广泛推广应用于此类项目的实施。
