摘　　要：对于有特殊使用功能,高大空间钢桁架的钢筋混凝土楼板施工,3种支撑方案可满足施工要求。综合对比后,采用基于钢桁架(下弦钢梁下翼缘的钢管扣件式)施工的斜向模板支撑结构,打破常规,突破压型钢板辅助钢桁架结构钢筋混凝土楼板施工的局限性,在一定程度上实现了施工工艺的创新。既节省空间,还简便快捷,缩短工期,为高品质、高质量履约打下坚实基础,实践证明,具有良好的社会、经济效益。For the construction of reinforced concrete floor slabs with special functions and tall space steel trusses,three support schemes can meet the construction requirements.After comprehensive comparison,the inclined formwork support structure based on the construction of steel trusses(steel tube fastener type of the lower flange of the lower chord steel beam)is adopted,which breaks the convention and breaks through the limitations of the reinforced concrete floor construction of the profiled steel plate-assisted steel truss structure.To a certain extent,the innovation of construction technology has been realized.It not only saves space,but also is simple and quick,and shortens the construction period.Lay a solid foundation for high-quality and high-quality contract performance.Practice has proved that it has good social and economic benefits.
