Abstract (en)
[origin: EP0152609A2] 1. Self-supporting composite slab for false floors, ceilings or the like, with a tray-formed outer cladding of sheet metal, preferably sheet steel, and a hardenable mineral filling material, e.g. anhydride, which can be introduced into this cladding in flowable state, wherein the bonding action between the hardened filling material and the tray-formed cladding is created by punctures (punchings) provided in the bottom and side walls of the latter, with inwardly projecting ragged edges, and wherein moreover the tray-formed cladding is coated externally with a layer preventing the outflow of the filling material through the punctures, characterized in that the layer preventing the outflow of the mineral filling material (12), e.g. anhydrite, consists of a surface protecting and/or improving medium applied while fluid or plastic and then hardened, which closes as a continuous skin (19) the multiplicity of punctures (13) (punchings) produced similar to a grater in the tray-formed cladding (11) with suitably small clear diameter.
