大跨度预应力无梁楼板深化设计要点及施工技术措施

Key points of deepening design of large-span prestressed beamless floor and construction technical measures

预应力无梁楼盖是一种高质量工艺要求的施工方法。在施工前需要深化设计,深化设计后,严格采取施工技术措施,合理地安排了工序和衔接,主要是关于预应力筋定位、张拉工艺的方法和标准来制定。然后根据具体施工的情况,确定是否采用了科学预应力筋施工措施,以有效保证张拉筋的施工质量。

The prestressed beamless floor is a construction method with high-quality process requirements.Before construction,it is necessary to deepen the design.After deepening the design,the construction technical measures are strictly adopted,and the working procedure and connection are reasonably arranged,which are mainly about the method and standard of prestressed reinforcement positioning and tensioning technology.Then according to the specific construction situation,determine whether the scientific prestressed reinforcement construction measures are adopted to effectively ensure the construction quality of the tensioning reinforcement.
