摘　　要：与常规的混凝土楼板施工相比,预应力现浇混凝土密肋空心楼盖具有自重轻、承载力大,抗震性能强、耐火性能好等优点,能实现房屋大空间、高净空需求,且能大幅度节约钢材和混凝土用量。结合工程实例对楼盖体系方案综合比选,并阐述了在大跨度楼盖施工中后张法预应力现浇密肋空心板工法的施工工艺,为同类工程施工提供参考。compared to conventional concrete slab construction, prestressed hollow-ribbed cast concrete floor with a light weight, large capacity, strong seismic performance, fire resistance, etc., can achieve large housing space, high headroom requirements and can save a significant amount of steel and concrete.In this paper, the project example floor plan for comprehensive comparison and selection system, and elaborated construction technology of prestressed hollow-ribbed cast construction method after long span floor construction, engineering applied to work for the same reference.
