摘要
通过天元港中心(A区)工程实际,详细介绍了无黏结预应力体系的施工方法和注意事项。通过采用单向预应力空心板楼盖,实现了普通钢筋混凝土结构无法实现的大跨度平板楼盖结构,同时保证了楼盖的刚度、抗裂度等问题;有效减轻了大跨度楼板的结构自重。
The author introduces in detail the construction method and the attention items of unbonded prestress system in Tianyuangang Center Project A Area.Unidirectional prestress hollow slab floor can realize large-span flat plate floor,and assures rigidity and anti-crack performance of the floor,and reduces effectively structure self-weight of large-span floor.
