Research and Application of Pre-Stressed Concrete Composite Slabs
The pre-stressed concrete composite slab, which combines the advantages of cast-in-place slabs and precast slabs, has promising development prospects. In the paper, according to structural integrity, bond performance, sound insulation, thermal preservation and construction techniques, four categories composite slab, such as the composite slab with flat bottom panel (including the composite slab with bar truss reinforced precast concrete bottom panel), the concrete composite slab with precast ribbed panel, the composite slab with hollow bottom panel and the composite slab with sandwich bottom panel are studied. The composite slab with flat bottom panel has poor structural integrity, and its bond performance and crack resistance of edge joint details need to be improved; the composite slab with bar truss reinforced precast concrete bottom panel has enough bond force, but its storage and transportation are inconvenient; the concrete composite slab with precast ribbed panel has good structural integrity and convenient construction procedure; the composite slab with hollow bottom panel and the composite slab with sandwich bottom panel have functions of sound insulation and thermal preservation, however they are inadequacy to resist bending moment and have complex construction procedure. The concrete composite slab with precast ribbed panel is provided with good mechanical behavior, economy and practicability, and is worth further researching and promoting.
