Abstract
The present invention relates to a cast-in-situ reinforced concrete floor which comprises a cast-in-situ reinforced concrete slab (1), a cast-in-situ reinforced concrete lower rib (2) and a cast-in-situ reinforced concrete lacing pier (3), wherein the cast-in-situ reinforced concrete slab (1) and the cast-in-situ reinforced concrete lower rib (2) are connected by the cast-in-situ reinforced concrete lacing pier (3) to form a whole body. In this way, a floor in spatial structure, with simple structure, is formed. The strength and the rigidity of the floor slab are largely increased, and the thickness of a cast-in-situ reinforced concrete can be correspondingly greatly thinned, the weight is reduced, the material consumption is reduced, and the shock resistance is enhanced. Simultaneously, construction pipelines can conveniently cross over the open web of the floor, and therefore, the structural layer height is reduced. The present invention is suitable for various floors, roofs, foundation slabs, open web bridges, etc.
Description
