US 6,698,148 B1 · Demountable modular floor for watertight raised decks

Abstract

A demountable modular floor for watertight raised decks consisting of a plurality of modularly assemblable composite slabs made of steel sheet and concrete, provided with a drainage system for collecting and conveying the rainwater between the slabs, wherein each composite slab comprises a bottom element (1) made of corrugated metal sheet surrounded by four suitably shaped metal sections (2, 3) and filled with a concrete layer (14), as well as four segments of upwardly open gutters (6, 7) peripherally arranged around said composite slab. The structure is completed by grid elements (8) covering the gutters (6) of larger width. The floor structure allows a rapid setting up of the raised deck and, at the same time, it affords the total dismantling thereof and prevents any seepage or leakage of water towards the underlying area.

Dependent claims

A demountable modular floor for raised decks consisting of modular quadrilateral units, each of which comprising:

a composite floor slab with a bottom element made of corrugated metal sheet, consisting of one or more pieces, according to the size, surrounded by four metal sections forming the side walls of said slab, and a layer of concrete cast on said bottom element of corrugated metal sheet and confined by said side walls, said metal sections forming said side walls having a cross-section substantially in the shape of a Z or of an S with square loops, and
four segments of upwardly open gutters, peripherally arranged around said composite floor slab and adjacent to said side wall sections, housed in channels defined by pairs of side wall sections belonging to adjacent composite floor slabs.
