Abstract: Multifunctional modular mother-beam built in structural steel or similar light, sturdy material, with a “U” configuration and provided with holes along its entire length, either on the back side, on the flanks, or on the edges, by which said mother-beams connect to one another either through their back sides, their flanks, or their edges, at any angle. They are fastened with screws inserted into said holes, with no need for welding. The flanks and edges are bended to facilitate fitting and fastening of the mother-beams. Mother-beams may connect by overlapping their back sides, by joining their edges, by joining their flanks, by joining flanks with edges, edges or flanks with the back side, through direct or reversed connection. It can act as a beam, pillar, trussed beam or bar, being especially useful in the construction of large areas, such as pavilions or similar constructions.
