Large-span multi-layer cantilever structure connecting column supporting construction method
The invention discloses a large-span multi-layer cantilever structure connecting column support construction method, which belongs to the technical field of building construction, and comprises the following steps: step 1, designing a multi-layer cantilever structure support, and determining the position of a foundation below a multi-layer cantilever area; secondly, foundation reinforcement is conducted on a foundation below the multi-layer cantilever area; thirdly, a plurality of steel pipe columns supported on the steel frame beams of the cantilever area on the lowermost layer are additionally arranged; fourthly, a plurality of layers of overhanging structure supports are erected, and the overhanging area frame columns are aligned with the steel pipe columns in a one-to-one axis mode; fifthly, structural construction of the cantilever area is conducted; sixthly, the steel pipe columns, the formwork supporting frame bodies and the formworks in the cantilever area are dismantled; a steel pipe column is arranged at the bottom of a frame column in a cantilever area for supporting, the axis of the steel pipe column is aligned with the axis of the frame column, the steel pipe column is considered according to a stress column, an original cantilever structure stress system is converted into a frame simply-supported structure stress system, force transmission is clear, and a stable structure is formed.
本发明公开了一种大跨度多层悬挑结构接柱支撑施工方法，属于建筑施工技术领域，包括如下步骤：步骤一、设计多层悬挑结构支撑，并确定多层悬挑区域下方的地基位置；步骤二、对多层悬挑区域下方的地基进行基础加固；步骤三、增设多个支撑在最下层悬挑区域钢框架梁的钢管柱；步骤四、搭设多层悬挑结构支撑，使悬挑区域框架柱与所述钢管柱一一轴心对正；步骤五、悬挑区域的结构施工；步骤六、拆除悬挑区域的钢管柱、模板支撑架体和模板；在悬挑区域框架柱底设置钢管柱进行支撑，钢管柱轴心与框架柱轴心对正，钢管柱按受力柱考虑，使原悬挑结构受力体系转换为框架简支结构受力体系，传力明确，形成稳定结构。
