Research on Construction Technology of Light Cast-in-place Floor Slab of Built-in Special Y-shaped Steel Plates

The existing Cast-in-place reinforced concrete floor slab still has some shortcomings as the cracks caused by shrinkage, temperature difference and settlement of the Cast-in-place concrete are difficult to control, a large amount of on-site wet operation leads to noise and environmental pollution, and the self weight of the Cast-in-place concrete floor slab is big, thereby bringing a lot of adverse influences. This paper innovates on the conventional Cast-in-place reinforced concrete, establishes the construction technology of the light Cast-in-place floor slab of built-in special Y-shaped steel plates, and introduces technology principle, application scope, technological features, technology process and operating points of the technology.
