现浇混凝土密肋空心楼盖探讨

Discussion on Cast-in-situ Hollow-ribbed Concrete Floor

现浇混凝土密肋空心楼盖具有刚度大、自重轻、抗裂性好、隔声效果好等优点。给出了拟板法计算此楼盖的要点,并以某楼板为例,分别采用现浇混凝土密肋空心楼盖与普通双向楼盖,对比分析了其经济技术指标。结果表明,现浇混凝土密肋空心楼盖,施工方便、经济合理,是一种优良的楼盖体系,在实际工程中值得采用。

The cast-in-situ hollow-ribbed concrete floor is provided with big stiffness,light weight and good crack resistance as well as good sound insulation effect.The main points about simulated plate method are outlined in calculating this type of floor.Besides,taking some floor as example,economic and technical indexes are compared by respectively adopting cast-in-situ hollow-ribbed floor and common two-dimensional floor.The results present that cast-in-situ hollow-ribbed concrete floor is a good floor system because of its convenience construction and reasonable economy,which is worthy to be applied in projects.
