Beam for concrete structures, characterized because the horizontal structure is formed by prefabricated prestressed concrete elements that have at their ends a lower flat extension and a built-in metal profile, located above said extension, whose elements are placed next to each other the other supporting the said metal profiles in the reinforcement of the beams of the structure, so that the lower protruding flat parts cover the lower face of these, forming a formwork around said reinforcement, completing the horizontal structure thus formed with rounds located in channels arranged longitudinally on the upper face of said prefabricated elements, which are joined to the frame of the jacena, in whose formwork is filled with concrete.
