Abstract: A supporting element for cylindrical or column-shaped elements of modular elements for making raised and/or ventilated floors, includes a substantially plane base configured to be rested on the underlying floor, two or more lateral extensions arranged at sides of the plane base and coplanar with the plane base, coupling elements arranged on the portions of said lateral extensions that are far from the plane base. The supporting element includes a first series of projections arranged along a circle centered on the plane base, defining a seat in which a lower end of the cylindrical or column-shaped elements is inserted and housed, and wherein the projections of the first series are configured to adhere to the surface of the cylindrical or column-shaped element housed in the seat.

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.

Abstract: A modular element or semi-module for making underground structures of basins for the management of meteoric waters or for retaining soil includes a substantially planar base portion and one or more pillars rising from the base portion. Each pillar is hollow and has a first external wall defining at least one internal cavity, inside the cavity there being an internal tubular stiffening wall that is spaced from the external wall and has a prismatic shape or a shape substantially corresponding to that of the external wall.

Abstract: A connecting and plugging element for modular floor construction comprising a modular element having a substantially U-shaped cross section defined by two lateral walls connected by an arched surface, and further having two head walls each connecting the two lateral walls on opposing sides of the modular element. The connecting and plugging element is preferably made of a thermoplastic material, and the two lateral walls and one of the head walls may have free edges that extend to form an enlarged bearing base with holes for connecting to the floor base and also with couplers or relieves for connecting to reinforcing bars or to adjacent connecting and plugging elements.

Abstract: A re-usable modular formwork comprising at least one panel having edge ribs and transversal ribs, each of the ribs comprising two parallel walls perpendicular to the formwork panel and preferably perpendicular to the walls of the rib and to the panel. Said ribs are disposed along the perimeter of the panel and transversally to the panel. Other ribs of smaller height may be positioned diagonally within the square or rectangular areas delimited by the edge ribs and the transversal ribs. Where two or more main transversal ribs and/or edge ribs intersect, these ribs have rounded joints. Centrally in said rounded joints, there is an opening for introducing a containing rod. Other openings may be present on the edge ribs for inserting and locking closing keys.

Abstract: A connecting and plugging element for modular floor construction comprising a linear element having a substantially U-shaped cross section defined by two lateral walls connected by an arched surface, and further having two head walls each connecting the two lateral walls on opposing sides of the linear element. The connecting and plugging element is preferably made of a thermoplastic material, and the two lateral walls and one of the head walls may have free edges that extend to form an enlarged bearing base with holes for connecting to the floor base and also with couplers or relieves for connecting to reinforcing bars or to adjacent connecting and plugging elements.
