Abstract:
Sheet metal plate (10) for creating flooring, particularly of industrial vehicles, over which trucks are to run, having a plurality of patterns, the maximum height of said reliefs ranging between 0.2 and 1.5 mm, said reliefs having a friction surface which has a mean width of at least 1 mm, in which said reliefs are arranged in a plurality of aligned groups of reliefs all of the same shape, the same orientation, and with their centres of gravity substantially aligned in one and the same given direction (D), the minimum distance, measured in said direction (D), between two adjacent reliefs of one and the same aligned group being less than 6 mm. The direction (D) in which the aligned groups are aligned advantageously coincides with the direction (De) in which the trucks run. A test measuring vibration can be used to characterize the ability of the sheet metal plate to emit noise of low intensity without the need to resort to acoustic pressure measurements on industrial vehicles. For preference, this is a sheet metal plate produced by rolling with a final pass over an engraved cylinder.
Abstract:
The invention relates to a composite metallic panel for the building industry that comprises at least two metallic sheets (21) and (22) substantially parallel and, arranged between them, profiles (3) substantially parallel provided between said metallic sheets and attached thereto, characterised in that said profiles, i.e. at least three of them, are used as spacers for separating said metallic sheets and are arranged so that the mean distance between two adjacent profiles is not necessarily uniform but adapted to the local conditions of use of said panel. In order to obtain a panel exhibiting an optimal balance between the weight and performance thereof, light alloys and aluminium in particular are preferred. The composite panels of the invention are particularly useful as a floor in a rolling vehicle, as a floor, bridge and/or ramp in a floating vehicle, or as a floor in a flying vehicle.
