Abstract

A system for constructing raised floors includes a plurality of bases to be laid on a laying surface, and a plurality of upper modular elements or modules to be laid on the bases. A service cavity is created between the modules and the bases for the passage of cables, cable ducts, raceways, and/or for ventilation purposes. Each module has an upper part and support feet, and each base has a raised part or cup-shaped element, the upper edge of which is configured to support a foot of one or more of the modules, the one or more modules and the cup-shaped element being mutually constrained. Each of the bases also includes one or more arms and/or connecting portions, removably or non-removably constrained to the cup-shaped element and configured to mutually constrain two or more bases.
