摘要
介绍一种新型预应力混凝土空腹板楼盖的应用研究和技术经济指标。这种预应力混凝土空腹板楼盖的承重体系是网格状的工字形截面肋梁结构,能用更少的材料跨越更大的空间,空腹率高达70%,经济跨度可达24m,并且兼顾梁式楼盖和板式楼盖之所长,具有受力明确、外观平整、造价低廉、设计简单、施工方便的特点,是大跨度楼盖的理想结构形式。
A new style of prestressed concrete hollow floor and its economic indexes are introduced. The structure system of the floor is a prestressed beam system with I-sections, which can span large space, the ratio of the hollow core has reached 70% , and the economic span has reached 24m. The floor has advantage of clear mechanics, smooth surfaces, lower cost, simple design method and easy construction, so it is an ideal style of large span floor system.
