A joist for constructions, characterized in that it is constituted by a piece of variable length and height, whose section has a double T shape and the smaller sides are inclined convergently inwards. From section to section, depending on the length of the joist, this is reinforced by means of projections of quadrangular section, reinforced in turn with rounds of iron of different diameters that go from the upper part to the lower one, forming a rectangle. The outgoing referents are also provided with reinforcements in their upper and lower part, forming trapezoids that enclose bars that longitudinally cross the whole beam and that constitute a metallic reinforcement in conjunction with the other reinforcements described.
