(57) The object of the invention is a system to be used in the roofs, ceilings and floors of buildings, formed by a composite beam (2, 12) and composite plate (1), which system consists of a composite beam (2), composite plates (1) carried by this, and a cast component (9), and in which the composite beam (2, 12) is formed of one or more profile plates. The intention of the invention is to simplify the reinforcement of the system. According to the invention the composite beam (2, 12) extends close to the upper surface of the cast component (9) and the upper section (4) of the composite beam (2, 12) are penetrated by several transverse long rods (8) and/or bolts, which extend for a considerable distance outwards from the upper edge of the composite beam (2, 12) in such a way that they act as upper surface reinforcement of the continuous slab or as a part of it at the point of support.
