Definitions

  • the invention relates to a ladder-like grate made of sheet steel for drainage channels, which is provided with longitudinal edges which are raised and angled to the opposite longitudinal edge and with supporting webs arranged between the longitudinal edges, each of which is separated from each adjacent supporting web by an inlet slot which one in the direction of the Elevation of the longitudinal edges beaded and parallel to each support web in a sloping inlet surface has edge.
  • Drainage channels are designed to drain traffic areas. They absorb accumulated rainwater in a line and pass it on. Drainage channels are formed by lining up channel elements, which are elongated drainage objects with a trough-shaped cross-section, which are covered by grids or lids. The drainage channels are classified according to their installation location.
  • a grating force of 15 kN is applied to gratings for traffic areas that are only used by pedestrians and cyclists - class A -; on grates for walkways, pedestrian areas, car parking areas and car parking decks - class B -, a test force of 125 kN; on gratings for curbs in streets and pedestrian streets, guiding and hard shoulder, parking areas - class C -, a test force of 250kN.
  • the low force test grates of the type mentioned are sufficient; the medium power only conditionally; no longer the one for heavy loads.
  • Cast iron grates are therefore used for medium and large loads. Cast iron grates are heavy and expensive compared to grates of the type mentioned at the beginning. They are also brittle, so that there is a risk of breakage when handling - transport, installation, installation and removal for cleaning - as well as with asymmetrical loading.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of designing a grate from sheet steel for drainage channels so that it can withstand increased loads.
  • the advantages achieved by the invention are essentially to be seen in the fact that the grate not only withstands all loadings, including those of groups B and C, but is light and nevertheless unbreakable.
  • the grate according to the invention is additionally stabilized in the transverse direction by the support webs and in the longitudinal direction by the side webs of the inner grate.
  • it is provided to assign inner gratings of different sheet thicknesses to an outer grate of a certain sheet thickness, so as to adapt the load-bearing capacity to the loads.
  • the limit in the possible variations is only the back width of the support bar of the inner grille, which is placed in the support bar of the outer grate.
  • the outer and inner grate can be produced in a known manner from sendzimier galvanized steel sheet, from steel sheet which is hot-dip galvanized after being deformed, or from stainless steel sheet. It is advantageous to stamp the outer grating on the surface in the usual way for anti-slip protection.
  • the grate for drainage channels chosen as an exemplary embodiment consists of an outer grate 1 and an inner grate 2 fastened in the outer grate.
  • the outer grate 1 and inner grate 2 are formed like a ladder and are made of sheet steel.
  • the outer grate 1 has two longitudinal edges 11, each of which consists of a raised surface 12 and a surface 13 angled to the opposite longitudinal edge.
  • Support webs 14 are provided between the longitudinal edges 11.
  • the supporting webs 14 are provided with stop knobs 15 projecting outwards.
  • An inlet slot 16 is provided between adjacent supporting webs 14.
  • Each inlet slot 16 has an edge 18 which is beaded in the direction of the raised surface 12 and merges parallel to each supporting web 14 into an inclined inlet surface 17.
  • the inner grate 2 is formed by two side webs 21 and by support webs 22 formed between the side webs 21.
  • the inner grid 2 is held with its side webs 21 between the angled longitudinal edges 11 of the outer grid 1.
  • the support webs 22 of the inner grate 2 rest on the support webs 14 of the outer grate 1.
  • the side webs 21 of the inner grate 2 are each formed from a raised edge strip of one of the steel sheets.
  • the support webs 22 are designed in the manner of an inverted channel. In cross section, an inverted U-profile is created. With their back 23, the support webs 22 of the inner grate 2 lie against the support webs 14 of the outer grate 1 on the inside. With the end faces 24 of their side walls 25, the supporting webs 22 abut the side webs 21. The back 23 of each support web 22 merges into the side webs 21 at the end faces.
  • the inlet slots 16 can be provided at a predetermined distance of the outer grating 1 possibly - as in the exemplary embodiment - only one supporting strut 22 of the inner grating 2 bears against every second supporting web 14 of the outer grating 1. If the inlet slits 16 are arranged at a greater distance from one another in the outer grate 1 or the raised surface 12 is made shorter, the principle that both the outer grate 1 and the inner grate 2 are each made from a steel sheet can still be made on each supporting web 14 of the outer grate 1, a supporting web 22 of the inner grate 2 is created.
  • the load capacity of the grate can also be increased in that a stronger steel sheet is used for the inner grate 2, whereby both the side webs 21 and the support webs 22 receive thicker side walls, which increases the stability.
  • the inner grate 2 is held in the outer grate 1 once with its side webs 21 between the angled longitudinal edges 11, and secondly with its support webs 22 in contact with the support webs 14 between the angled inlet surfaces 17.
  • the inner grate 2 is held immovably in the outer grate 1, without additional attachment.
  • the easiest way to produce the grate is using the following method: in a steel sheet provided for the outer grate 1, depressions and the stop lugs 15 are pressed in the first operation. Separately, the outlines of the side webs 21 and the support webs 22 are cut and cut into a steel sheet provided for the inner grate 2 at the same time. In the second step, in the steel sheet provided for the outer grate 1 the hollows cut open and the end pieces trimmed. Separately, the side walls 25 of the supporting webs 22 of the inner grate 2 are raised at the same time. In the third step, the inlet surfaces 16 are raised on the supporting webs 14 and the longitudinal edges 11 of the outer grate 1.
  • the side webs 21 of the inner grate 2 are raised at the same time.
  • the inner grate 2 is then inserted into the outer grate 1, so that the supporting webs 22 lie in the supporting webs 14.
  • the longitudinal edges 11 of the outer grate 1 are then angled and pressed around the side webs 21 of the inner grate 2. The above operations are carried out on the same press in a step tool.
