Definitions

  • the invention relates to a cover grate for a drainage channel, a yard drain or the like surface drainage devices according to claim 1.
  • Known covering grates therefore have, in addition to support areas for placing the grate on an upper edge of a gutter body which can be installed in the floor, drainage box or the like body further supporting structures, via which the loads can be absorbed. These structures are designed so that due to their geometry and due to a high material use considerable burdens are transferable.
  • a cover grate with the features of the preamble of claim 1 is described in the German design M9305852.7.
  • Fig. 3 Shown is a plan view of an underside of a commercially available cover grille 1.
  • support structures 8 are formed on a lower surface of the cover grating 1, wherein in particular an integrated in the support structures 8 support area 10 for placing the cover grating 1 on an upper edge of a can be installed in the ground gutter body, drain box or the like body is designed so that there is a stable construction due to a high material usage.
  • the invention has the object of providing a cover grate for a drainage channel, a Hofablauf or the like surface drainage facilities to go further, that despite reduced use of materials, an increase in the stability of the grates is achieved.
  • cover grate is designed so that material is saved, but the construction can still absorb high loads. Surprisingly, it has been shown that a reduced voids formation and crack formation can be achieved by the construction according to the invention.
  • the cover grate in a preferred embodiment that the outer contour of the support structures is flattened in the support area. This has the particular advantage that material can be saved due to a flattening, but the wall thicknesses of the support structures in the surface direction can be considered to be the same with respect to a cast construction with these size ratios substantially in all areas.
  • the outer contour areas and thus the support areas are designed substantially wave-shaped.
  • material accumulations as shown in the prior art, in particular in the area of the support section approaches can be avoided, because the outer contour of the support areas substantially equalizes the inner contour of the support areas.
  • the support structures have substantially equal wall thicknesses in the surface direction, in particular in the support areas. Due to the uniform wall thickness, a construction is provided in addition to the material saving, which has a high degree of stability despite a reduced use of material. This is due to the improved cooling characteristics of cast structures with the same wall thicknesses justifiable, so that inner voids, Seigerept, cracking and distortion are largely avoided. A reduced use of materials also reduces the manufacturing and transport costs of the cast components and allows their better handling.
  • a distance between adjacent support sections is greater than a width of the drainage openings.
  • the width of the drainage openings is therefore largely independent of the distance of the support sections, because the width is defined by the plate body.
  • the width of the drainage holes is thus independent from the distance of the support sections.
  • the support sections can accordingly be designed according to the desired, in particular reduced wall thickness in the surface direction, in order to achieve a material saving or to design the wall thicknesses in such a way that a high stability of the entire support structure is ensured.
  • the wall thicknesses in the surface direction of the support structures in this exemplary embodiment are thus essentially the same over their entire expansion range.
  • the covering grates are made of cast iron or plastic.
  • roofing grates made of cast iron have enormous stability and very good damping properties.
  • the special geometry of the grids is extremely economical to produce by a cast construction, in particular material and time-saving. Also, the geometry of plastic grids is easy to implement, for example by pressing.
  • Fig. 1 shows a plan view of a bottom 3 of a cover grille 1 according to the invention in one embodiment.
  • Fig. 2 shows a sectional view along the section line II - II out Fig. 1 ,
  • the cover grille 1 has a walk-on and / or drive-over top 2 and the bottom 3.
  • the upper side 2 is formed by a surface 5 of a substantially plane-parallel plate body 4.
  • the underside 3 has support structures 8 on a lower surface 6 of the plate body 4, which are integrally connected to the plate body 4 and extending in a direction perpendicular to the extension direction of the surface 5 of the plane-parallel plate body 4.
  • a plurality of drainage holes 7 are defined by the plane-parallel plate body 4.
  • the support structures 8 are formed by support sections 9 and support areas 10 for placing the cover grating 1 on an upper edge of a gutter body, drain box or the like body (not shown) which can be installed in the floor.
  • the support areas 10 are not only to be understood as a surface, but form the support structure 8, ie they extend perpendicular to the extension direction of the surface 5.
  • the support portions 9 each extend between opposing support areas 10, perpendicular to a direction indicated by an arrow longitudinal direction L of the covering grates 1, wherein between the support portions 9, a part of the lower surface 6 of the plane-parallel plate body 4 is visible in which the drainage holes 7 are formed.
  • the support areas 10 of the cover grille 1 surround narrow sides S E of the drainage openings 7, wherein the support areas 10 and the drainage openings 7 are spaced from each other by the plane-parallel plate body 4.
  • two drainage openings 7 each are enclosed by two support sections 9, wherein the drainage openings 7 are arranged perpendicular to the longitudinal direction L of the cover grates 1, one below the other and of different lengths.
  • further drainage openings 7 may be arranged within two support sections 9, or only one drainage opening 7 is formed. Also, their arrangement and size, for example, depending on the application of the Abdeckrostes 1 can be varied. Thus, a plurality of small drainage holes 7 are arranged, if with a strong contamination in the field, eg. B. must be expected by foliage.
  • outer contours 11 of the support structures 8 in the support areas 10 of the cover grating 1 are flattened. Due to a flattening 13 material can be saved, with wall thicknesses D in the surface direction of the support structures. 8 In particular, in the case of a cast construction with the proportions shown essentially in all areas can be considered the same.
  • the exemplary embodiment shows supporting regions 10, the outer contour regions 11 of which are designed to be substantially wave-shaped.
  • accumulations of material as shown in the prior art, can be avoided, in particular in the area of the support section approaches, because the outer contour 11 essentially adapts to an inner contour 12 of the support regions 10.
  • the support structures 8 accordingly have the same wall thicknesses D in the surface area in the support areas 10. Due to the uniform wall thickness D, a construction is provided in addition to the material saving, which has a high degree of stability despite a reduced use of material. This is due to the improved cooling characteristics of cast structures with the same wall thicknesses D justifiable, so that Innerlunker, Seigerept, cracking and distortion are largely avoided. A reduced use of materials also reduces the manufacturing and transport costs of the cast components and allows their better handling.
  • the lower surface 6 of the plane-parallel plate body 4 is shown. Since a distance A between adjacent support sections 9 is greater than a width B E of the drainage openings 7, the lower surface 6 of the plate body 4 is visible as a border of the drainage openings 7.
  • the width B E of the drainage openings 7 is thus largely independent of the distance A of the support sections 9, because the width B E is defined by the plate body 4.
  • the support sections 9 can accordingly be designed according to the desired, in particular reduced wall thickness D in the surface direction in order to achieve a material saving or to design the wall thicknesses D in such a way that a high stability of the entire support structure 8 is ensured.
  • the wall thicknesses D in the surface direction of the support structures 8 are thus substantially the same over their entire expansion range in this exemplary embodiment.
  • cover grate 1 is made for example of cast iron. Covering grids 1 made of cast iron have enormous stability and very good damping properties.
  • the special geometry of the cover grates 1 is extremely economical to produce by a cast construction, in particular material and time-saving.
  • the cover grille 1 is made with this special geometry Plastic can be formed. The geometry can then be realized in addition to a casting process, for example, via a pressing process.
