Definitions

  • the invention relates to a drainage channel with a gutter cover and a gutter cover for a drainage channel.
  • Gutter cover for drainage gutters usually consist of a cover plate with a supporting support grid with two elongated load struts resting on the frame and transversely to the load struts extending transverse or support struts which integrally connected in heavier loads usually in the form of a one-piece cast metal part with the load struts are.
  • the load struts lie on the frame of an upwardly open drainage channel, wherein the support struts or transverse struts which, when driving over, e.g. of a motor vehicle recorded load on the load struts to the gutter.
  • the load struts usually have a not inconsiderable extent, for example, 1 to 5 cm.
  • the gutter cover thus formed is very rigid and is usually only at a few points on the frame of the gutter, whereby on the one hand in the gutter cover comparatively high bending forces occur and on the other hand on the gutter at the few points where the load strut rests on the frame, a significantly excessive pressure stress on the channel occurs. In this way, despite a sufficiently strong design of the individual components, the strength of the overall design is sometimes compromised, or the individual components must be oversized to account for this problem.
  • Advantageous developments of the invention are the subject of the dependent claims.
  • each recess is arranged in the longitudinal direction of the channel in a region between two transverse or support struts. This then leads to the connection region of the load strut with the transverse strut resting directly on the frame, as a result of which a load introduced onto the cross strut is discharged directly onto the frame, without resulting in excessive excessively high stresses in adjacent areas.
  • the reduction of the material thickness through the recesses is preferably achieved in the form of round, curved or arcuate recesses which do not cause stress peaks in the material.
  • the gutter cover can also be designed such that the cross struts extend further towards the support side of the cover downwards than the load struts. This leads to the fact that the gutter cover ultimately rests with the cross struts and not with the load struts on the frame. There are thus many support points created on the frame, which are interconnected by material-reduced areas of the load struts, which in turn increases the elasticity of the channel cover and thus the uniform distribution of the total load on many points of the frame. This also reduces bending loads in the gutter cover itself.
  • the recesses on the load struts or the vertical resetting of the load strut relative to the cross struts when they rest on the frame should preferably be so strong that the rigidity of the regions reduced in thickness in the horizontal direction to a significant drop in rigidity and a corresponding increase in the Elasticity leads.
  • the height of the recesses should be at least 20% and at most 70% of the height of the load strut, preferably between 25 and 55%.
  • the cross struts against the load struts by at least 20%, at most 70% of the height of the load struts down against the frame before.
  • the gutter cover can be made of light metal, concrete, plastic, ceramic, sheet steel or stainless steel, but preferably of cast iron, in which case the problem of the rigidity of the gutter cover and the stress exaggeration at the few contact points of the frame becomes serious.
  • the frame is made of metal, e.g. Galvanized sheet steel and the drainage channel made of concrete or polymer concrete.
  • the channel can be made of other materials, such as e.g. Plastic or recycled plastic exist.
  • the recesses are preferably provided on the lower edge of the load strut.
  • the material reduction at the upper edge or in the form of recesses such as holes, ellipses or ovals, which are completely provided in the material of the load strut, that is not at one edge.
  • the material of the load struts next to the support areas also be reduced in thickness, wherein the thickness reduction is preferably between 20 and 60% of the thickness of the load strut. This also improves the elasticity of the load strut and thus the load distribution from the channel cover to the channel.
  • the gutter cover 10 consists of a horizontal plate 12 which has on its underside two longitudinally extending load struts 14, which are connected to the plate 12 and transversely to the trough longitudinal direction and the load struts 14 extending transverse struts 16. Between the transverse struts 16 and the load struts 14 openings 18 are formed in the cover plate 12 of the channel cover, through which water can enter via the channel cover 10 in a channel body.
  • the extending in the longitudinal direction of two load struts 14 have at its lower edge 20, which is designed to rest on the frame of a drainage channel, arcuate, upwardly extending recesses 22, which in the case shown about 50% - namely the height 1- the height L of the load strut extends into this.
  • the rigidity of the gutter cover 10 in the gutter longitudinal direction is greatly reduced and increases the elasticity, allowing a better load distribution of the forces acting on the gutter cover loads on the frame of a drainage channel.
  • FIG. 4 An alternative to this is shown in FIG.
  • the mounting position of the channel cover 30 of Figure 3 in a drainage channel is shown in Figure 4.
  • FIGS. 3 and 4 The second alternative of a gutter cover 30 according to the invention and its installation position in a gutter are described below.
  • the gutter cover 30 consists of a one-piece cast material comprising an upper cover plate 32, which comprises on its underside cross struts 34 and two longitudinal load struts 36 which are provided in the longitudinal direction of the gutter cover on both sides of openings 38 which between the upper covers 40 of the transverse struts 34th are formed in the cover plate 32 and the load struts 36.
  • the gutter cover 30 rests on a channel 50 on its frame 52, which are formed on both sides of an upwardly open inlet region 54.
  • the frames 52 are L-shaped and have a vertical leg 56 and at its lower end extending in the direction of the inlet region 54 horizontal leg 58, on which the downwardly slightly protruding cross struts 34 of the channel cover 30 rest.
  • the frames 52 are mounted on the concrete body 53 of the channel by means of anchoring in bekqannten way. In this way, the gutter cover 30 is corresponding to the number of transverse struts 34 on a plurality of load points, so that the load is transmitted as evenly as possible to the frame 52 and thus to the concrete body 53 of the channel 50.
