ABSTRACT:
The said structure presents a constitution which, as well as providing a great resistance, supposes an effective reduction of the depth of floor slabs and technical layers built with current construction systems while allowing the incorporation of various technical elements and installations. For this reason the structure comprises two horizontal frameworks forming respective grillages (1, 2) which are linked to each other by means of pyramidal caps (3), whose bases are joined to the frames formed by the lower grillage (2) while its uppermost verices are linked to the intersections (5) of the upper frame (1), for which reason the said intersections are located over the centers (6) of the openings of the lower grillage (2), allowing the making of the structure by means of two procedures, one in which pyramidal (10) and tetrahedral (12) molds are employed, another in which the same pyramidal (10) molds are used, but in combination with others of two types, some triangular (23) type and others (21) constituted by two intersected triangular prisms with coinciding quadrangular faces forming a whole (22).
