高效预应力圆孔板的特点及工程应用造价分析

Characters of High-quality Prestressed Conctete Slab and Cost Analysis of the Practical Design

介绍了采用新型高强材料生产的高效预应力混凝土圆孔板的结构特点 ,并对实际工程中现浇楼盖的设计进行了设计更改 ,对两种不同设计进行了材料用量、经济性能等方面的分析和比较 .结果表明 ,高效预应力混凝土圆孔板楼盖在几乎不增加造价的情况下 ,满足了现代建筑大开间的要求 ,又解决了现浇楼盖的裂缝问题 。

The characters of high-quality prestressed concrete slab are introduced. Based on design practices, the cast-in-place floor design is changed, and the analysis is conducted on consumption of materials and economy of two kinds of design. The results show that high-quality prestressed concrete slab floor is an ideal structure system, on the condition of a little increas in cost, which can not only solve the problem of cracking of cast-in-place floor but can also meet the long-span requirement.
