Abstract
The invention provides a cast-in-place concrete floor and a construction process thereof. A core-embedding core-forming process is adopted in the structure of the cast-in-place concrete floor, round high definition composite thin wall pipes are arranged on a floor bottom rib of the floor at intervals, and concrete is cast after the thin wall pipes are fixed. The floor cast in the mode can form a cast-in-place multipore hollow plate provided with countless small I beams for stress, and the small I beams can bear large shock, so that the floor has better shockproof effects. Further, self weight and construction materials of the floor are reduced due to the fact that using amount of the concrete is reduced, cost for constructing the floor is saved, and simultaneously safety factor of the floor is increased.
