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 ,是一种理想的结构形式
The structural characteristics of high-performance prestressed concrete circular orifice plates produced with new high-strength materials were introduced. The design of cast-in-place floor covers in actual projects was changed. The material consumption, economic performance, and other aspects of the two different designs were performed. Analysis and comparison. The results show that the high-efficiency prestressed concrete circular hole floor cover meets the requirements of the modern building with a large increase in the cost, and solves the crack problem of the cast-in-situ floor cover, which is an ideal structure type
