摘要
采用先张法预制空心板时,预应力钢绞线的张拉质量直接影响空心板的预制质量,因此预应力钢绞线的张拉是施工中应重点控制的环节。
Stretching quality of prestressed steel wires in the process of prefabricating cored slab directly impacts the quality of prefabricated cored slab, therefore stretching prestressed steel wires is the key tache needing to be controlled in construction.
