Steel pipe column underpinning construction method for beam-column core joint in reverse construction method
The invention relates to the technical field of building construction, in particular to a beam-column core joint steel pipe column underpinning construction method in a reverse construction method. According to the method, frame beams on a poured floor slab are supported in advance by installing a main supporting system, then the frame beams on the peripheral side of an original concrete filled steel tubular column are dismantled, and a supporting structure comprising a steel sleeve and an ejector rod assembly is arranged for secondary supporting. And then a newly-built concrete column is installed and poured at the original position, and meanwhile stable connection of a pouring mold structure and a supporting structure is ensured. The safety and stability of the frame beam during construction are effectively guaranteed, the safety of the whole building structure is improved, the position precision and the structural strength of the newly-built concrete column are guaranteed, and important practical application value is achieved.
本申请涉及建筑施工技术领域，尤其是涉及一种逆作法中梁柱核心节点钢管柱托换施工方法。该方法通过安装主支撑体系对已浇楼板上的框架梁进行预先支撑，接着拆除原钢管混凝土柱周侧的框架梁，并设置包含钢套管和顶杆组件的支护结构进行二次支撑。之后在原位置安装并浇筑新建混凝土柱，同时确保浇筑模具结构与支护结构的稳定连接。本发明有效保证了施工期间框架梁的安全稳定，提高了整体建筑结构的安全性，确保了新建混凝土柱的位置精度和结构强度，具有重要的实际应用价值。
