空心楼盖作为一种新型的无梁楼盖体系,在节能节材及经济性方面有突出优势。盒状内模空心楼盖由于其刚度在两跨度方向分布均匀、布模灵活、对异型边板适应性强和设计计算效率高的优点,应用最为广泛。本文以实际工程中常见跨度的车库为例,分别按现浇盒装内模空心楼盖和传统主次梁楼盖进行了结构设计,并计算了这两种楼盖的总造价,进行了施工技术和经济性方面的比较。本文可为空心楼盖结构设计和楼盖方案选取提供参考。 Hollow floor as a new type of non-beam floor system, energy saving material and economy have outstanding advantages. Box-shaped inner cavity hollow floor because of its stiffness in the two spans of the uniform distribution, flexible model, the adaptability of special-shaped edge and design and calculation of the advantages of high efficiency, the most widely used. In this paper, the actual span of the garage as an example, respectively, according to the cast-in-box hollow mold floor and the traditional primary and secondary floor beam structure design, and calculated the total cost of these two floor, the construction was carried out Technical and economic comparison. This article can provide a reference for the hollow floor structure design and floor plan selection.
