摘　　要：珠海前山旧村改造项目酒店转换层为大跨度型钢混凝土框支梁结构,转换层离地高度30 m(转换层以下为架空层),采用“空中支模、型钢吊拉、钢骨支撑”的模板支撑体系。由于转换层以下架空且离地高,同时转换层框支梁截面大,故框支梁模板支撑采用梁内钢骨吊拉形式施工。实践证明,“钢骨空中支模”施工方法优于传统支模方式,通过吊拉形式将框支梁模板施工荷载传递至梁内钢骨,满足高大截面框支梁施工要求。The conversion floor of the hotel in Zhuhai Qianshan Old Village Reconstruction Project is a large-span steel reinforced concrete frame supported beam structure.The conversion floor is 30 m above the ground(below the conversion floor is an overhead floor),and the formwork support system of"aerial formwork,section steel sus‐pension and steel skeleton support"is adopted.Since the conversion floor is overhead and high above the ground,and the frame support beam section of the conversion floor is large,the frame support beam formwork support is constructed by hanging and pulling the steel skeleton in the beam.The practice has proved that the construction method of"steel skeleton aerial formwork erection"is superior to the traditional formwork erection method.The construction load of the frame supported beam formwork is transferred to the steel skeleton in the beam through the hanging and pulling form,meeting the construction requirements of the frame supported beam with high section.
