Provided is a steel bar truss concrete prefabricated floor slab. Compared with a previous steel bar truss laminated slab, a laminated layer is removed, and a prefabricated layer (5) is reserved and the prefabricated layer (5) is on the top of a floor support plate. The prefabricated layer (5) comprises a concrete layer and a steel bar truss net. A steel bar truss is mainly formed by upper string reinforcing steel bars (1), lower string reinforcing steel bars (2), and web member reinforcing steel bars (3) connecting the upper string reinforcing steel bars (1) with the lower string reinforcing steel bars (2). The upper string reinforcing steel bars (1) are on the upper part of the prefabricated layer (5). The lower string reinforcing steel bars (2) just take corresponding anticorrosion and fireproof measures and protective coating measures. The upper part of the prefabricated layer (5) is provided with longitudinal distributed reinforcing steel bars (6) which are parallel to the upper string reinforcing steel bars (1), and lateral distributed reinforcing steel bars (4) which are distributed staggered with the upper string reinforcing steel bars (1). The steel bar truss concrete prefabricated floor slab is advantaged by realizing energy saving, material saving, and time saving, being convenient in construction, and shortening construction period.
