Definitions

  • the invention relates to a cover grate formed from sheet metal for channels with the features according to the preamble of the claim.
  • Cover gratings of this type are produced in a continuous process from a sheet metal strip, the inlet slots being punched out and the longitudinal folds and the subsequent longitudinal webs being formed by rolling. The longitudinal edges and the longitudinal webs are provided for support or for resting on the channel.
  • the crosspieces are only resistant to bending, as far as the integrally formed straight flanges extend, and beyond where the arches of the inlet slots start, there is no stiffening in the known drainage gratings, so that deformations can occur there under higher loads.
  • the invention has for its object to improve the bending stiffness of a drainage grate made of sheet metal with simple means without additional parts.
  • the grate is formed from a sheet metal strip in a continuous process (cold rolling). Folded longitudinal edges 10 are formed, which merge into a web 11, where a bead 12 is formed in each case.
  • inlet slots 13 and transverse webs 14 are delimited at each end by arches 13a, on which short collars are formed.
  • the crossbars 14 are each made in their straight areas by flanges 14a rigid. At the top 14 knobs 15 are formed on the crossbars to make the tread non-slip.
  • the transverse webs 14 are supported by the respective beads 12 where the straight flanges 14a end and the respective arches 13a of the inlet slots 13 begin.
