Joist for the perfected construction, characterized in that it constitutes a prestressed concrete spar that has an isosceles trapezoidal section, giving rise to the determination of two inclined lateral faces on a ramp converging upwards, in order to form an open wedge cavity between each two joists that it holds by itself to the vault of corresponding configuration that is placed between the two joists; the large part has a longitudinal channel centrally on its upper face that is filled with concrete from the floor layer that is deposited on site on the beam, improving the adhesion of this layer to the beam.
