- Abstract:
-
High-efficiency prestressed two-way laminated slab building cover is a new type of building cover system that is currently being studied and explored in China, which has the advantages of prefabricated and cast-in-place building covers. Combined with engineering examples, the use of this kind of building cover form instead of cast-in-place building cover, using high strength and low loose steel bar as prestressed ribs, using reasonable structural measures, to achieve the two-way force transmission of floor slab, the test shows that the integrity of high-efficiency prestressed two-way superimposed slab building cover is greatly enhanced, the bearing capacity and crack control ability are improved, and the requirements of large-span residential system such as large span, heavy load, and shape can be arbitrarily divided are met, which is an ideal building cover form in the future high-rise and large-span residential system.
