<p>The modular floor is used in civil engineering for building watertight raised decks, such as parking sites. Such a demountable modular floor for watertight raised decks consisting of a plurality of modularly assembled 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 large 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. 17 claims, 5 figures</p> |
