混凝土梁板结构是现阶段结构设计中很常用的结构形式,而板作为这种结构形式的重要组成部分,寻求一个比较经济合理的板厚对于整个结构设计和建筑物造价都是相当重要的。本文以肋梁楼盖的单向板为对象,参照现行混凝土和钢筋市场价格行情,通过控制最低造价考虑跨度、钢筋、楼面荷载以及混凝土强度的变化来讨论混凝土楼板板厚的变化规律,最终给出不同荷载、不同跨度、不同强度等级钢筋以及不同混凝土强度下楼板的经济厚度,供在进行楼板设计时借鉴和参考。
Concrete slab structure is very common in current structural design, and slab is an important part of this structure. Seeking a more economical and reasonable slab thickness is very important for the whole structural design and building cost. In this paper, we take the one-way slab of the ribbed floor as the object, and discuss the variation rule of the concrete slab thickness by referring to the market price of the current concrete and steel bar, controlling the span, the steel bar, the floor load and the concrete strength by controlling the minimum cost. The economic thickness of slab with different load, different span, different strength grades and different concrete strength is given for reference and reference in the design of slab.
