A reinforced concrete beam pre-fabricated in the workshop, characterized by the fact that, in it, the increase in width or width and height of the section of its head and its rib is ensured by integrating the section of the mass of the slab provided in the work, increasing, consequently, the resistant moment of the resulting beam. To this end, and in order to ensure the perfect connection between the mass and another, and to prevent cracks due to longitudinal forces or slides, said beam and its rib, or simply the last one, presents a series of grooves, grooves, ridges, corrugations, roughness and, mainly, a series of lateral teeth that serve as notches of engagement with the mass of the forging.
