Beschreibung
Zusammenfassung:	The utility model discloses a prestressed bidirectional ribbed composite floor slab, and belongs to the field of buildings. The prestressed bidirectional ribbed composite floor slab comprises a prefabricated prestressed bidirectional ribbed grooved bottom slab and cast-in-situ concrete which are poured to form the prestressed bidirectional ribbed composite floor slab. The prefabricated prestressed bidirectional ribbed grooved bottom slab comprises a ceramsite lightweight concrete layer, a reinforcing mesh and a plurality of prestressed reinforcements, the reinforcing mesh and the prestressed reinforcements are arranged in the ceramsite lightweight concrete layer, a plurality of hogging moment ribs are equidistantly arranged at the outer peripheral edge of the reinforcing mesh, and a plurality of weight reduction grooves are formed in the prefabricated prestressed bidirectional ribbed grooved bottom slab. The prestressed bidirectional ribbed composite floor slab is excellent in strength, rigidity, crack resist
