Abstract
A grating assembly comprises a plurality of inverted T-shaped cross pieces 2 each having a plurality of slots 3 in the upper flange. The slots have convexly curved central walls 4. A plurality of transverse profile bars 1 have curved lower flange portions 1c that engage in the slot curvatures when assembled. The latter is implemented by bending the pieces 2 to open the slot mouths and facilitate the bar insertions.
Claims3
A grating composed of interlocking and disassemblable longitudinal profile bars and slotted cross pieces, said cross pieces having an upper edge and intended for coverings, sheathings, etc., characterized in that the slots (3) punched in the cross pieces (2) extend from said upper edge and comprise a hollow defined by curved walls (4) at a certain distance from the upper edge (2a), in that the longitudinal profile bars (1) are without slots and their parts which engage in the slots of the cross pieces (2) comprise a wall part (1c) which is bent to one side, the convex side of this wall part is elastically compressed and frictionally bound against the one wall (4) of the hollow of the slot (3).
