PROBLEM TO BE SOLVED: To provide a reinforced concrete floor structure allowing an interval between beams 1 to be lengthened by reducing the self-weight of a floor slab, eliminating most of manual work at a job site, enabling a reduction in price and standard production, and serving as a reinforcing material for the floor slab or a supporting metallic material for equipment such as wiring, piping, etc., by exposing a three-dimensional welding reinforcement 2 in a lower part. SOLUTION: In this structure, a concrete slab 3 is laid between the beams 1 made of wide flange shapes, and the top surface of the concrete slab 3 is taken as that of the floor slab. The upper part of three-dimensional welding reinforcement 2 is buried for integral formation in the concrete slab 3 having a thickness t of 4, 7, or 10 cm. The reinforcement 2 is preferably fixed integrally to the top surface of the beam 1 through an approximately S-shaped cross-section jointing fitting though the wave bar of the reinforcement 2 can be made to abut on the flange 11 of the beam 1 and the concrete slab 3 can be directly placed on the top surface of the flange 11.
