空心楼板通过在厚板中埋入空心腔体,在降低楼板自重的同时保留了其较强的平面外抗弯刚度,因此常用于大跨度大空间的规则楼面板,该种楼板通过加入空腔来减少楼板自重和混凝土用量的特点也符合目前低能耗、可持续、集约型设计的时代潮流。本文对一种较为特殊的空心楼盖形式—周边刚性支承内置式圆管空心双向规则矩形楼板的简化设计及其相关问题进行深入讨论研究,提出了设计简化流程图,总结了简化设计中应当注意的问题,为该种楼板的实际工程应用提供了一种较为简洁、完整、合理的设计方法,并为空心楼板的设计发展提出了一定的思考。
Hollow floor through the hollow in the thick slab cavity, while reducing the weight of the floor while retaining its strong out of plane bending stiffness, it is often used in large-span large floor of the rules of the floor, the floor by adding the cavity To reduce the floor weight and the amount of concrete is also in line with the current low-power, sustainable, intensive design trend of the times. In this paper, a more special design of hollow floor - the simplified design and its related problems of the hollow circular two-way regular rectangular floor with built-in rigid surrounding pipe is discussed and discussed in detail. The simplified flow chart of the design is proposed, and the simplification of the design should be noted Which provides a simple, complete and reasonable design method for the practical engineering application of the kind of slab, and puts forward some thinking for the design and development of the hollow slab.
