在现代公共建筑中,由于使用功能的需要,大跨度、大开间的结构越来越多,现浇预应力空心楼板体系的应用,对比传统的普通钢筋混凝土结构体系,无论从结构受力特点、成型工艺、施工流程、和控制措施有其独到的特点;本文根据现行规范,制作后张法预应力空心楼板的技术条件,为其设计奠定理论基础,随后以一工程实例加以详细阐述。
In modern public buildings, due to the need of using function, the structure of large-span and large-span is more and more. The application of cast-in-situ prestressed hollow floor system, compared with the traditional common reinforced concrete structure system, The molding process, construction process and control measures have their own unique features. According to the current regulations, this paper makes the post-tensioning prefabricated hollow slab technical conditions and lays a theoretical foundation for its design, and then elaborates with a project example.
