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 and claim 2.
  • cover gratings therefore have, in addition to support areas for placing the grate on an upper edge of a channel body, drain box or similar body which can be installed in the floor, further supporting structures by means of which the loads can be absorbed. These structures are designed in such a way that due to their geometry and due to the high use of materials, considerable loads can be transferred.
  • FIG. 3 shows the current state of the art.
  • a top view of an underside of a commercially available cover grate 1 is shown.
  • Support structures 8 are formed on a lower surface of the cover grate 1, in particular a support area 10 integrated into the support structures 8 for placing the cover grate 1 on an upper edge of a gutter body, drain box or similar body that can be installed in the floor is designed in such a way that a stable construction results due to the high use of material.
  • the problem here is that, despite the high cost of materials, the safety against breakage is limited especially in massive material sections.
  • the invention is based on the object of developing a cover grate for a drainage channel, a yard drain or similar surface drainage devices in such a way that, despite the reduced use of material, an increase in the stability of the grate is achieved.
  • a cover grate for a drainage channel, a yard drain or similar surface drainage devices comprising a walk-on and / or drive-over upper side and a lower side with support areas for placing the cover grate on an upper edge of one in the
  • Floor-mountable channel body, drain box or similar body support sections between the support areas, and a zero number of drainage openings between the support sections, the support areas having an inner contour facing the drainage openings and an opposite, facing outward, substantially identical outer contour with the inner contour.
  • a cover grate for a drainage channel, a yard drain or similar surface drainage devices comprising a walkable and / or drive-over upper side which is formed by a surface of a substantially plane-parallel plate body, a number of drainage openings in the plate body and an underside with support Structures on a lower surface of the plate body, which are integrally connected to the plate body, wherein the support structures have support sections between the drainage openings and support areas for placing the cover grate on an upper edge of a gutter body, drain box or similar body that can be installed in the floor, the support structures in the surface direction have essentially the same wall thicknesses and / or the same inner contours and outer contours.
  • An essential point of the invention lies in the fact that the cover grate is designed in such a way that material is saved, but the construction can nevertheless absorb high loads. Surprisingly, it has been shown that the formation of voids and cracks can be reduced by the design according to the invention.
  • the cover grating 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 regarded as essentially the same in all areas with regard to a cast construction with these size ratios.
  • the outer contour areas and thus the support areas are designed to be essentially undulating. Material accumulations, as is shown in the prior art, can thus advantageously be avoided, in particular in the area of the support section attachments, because the outer contour of the support areas essentially adapts to the inner contour of the support areas.
  • the support structures accordingly have essentially the same 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 savings, which despite a reduced use of material has a high degree of stability. This can be justified by the improved cooling characteristics of cast structures with the same wall thicknesses, so that blowholes, segregation, cracking and warping are largely avoided. A reduced use of materials also lowers the manufacturing and transport costs of the cast components and allows them to be handled more easily.
  • 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 between the support sections, because the width is defined by the plate body.
  • the width of the drainage openings is therefore independent from the distance of the support sections.
  • the support sections can accordingly be designed in accordance with the desired, in particular reduced wall thickness in the surface direction, in particular in order to achieve material savings here too 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 are therefore essentially the same over their entire expansion range.
  • the cover grids are preferably made of cast iron or plastic.
  • Cover grates made of cast iron have enormous stability and very good damping properties.
  • the special geometry of the cover gratings can be manufactured extremely economically by means of a cast construction, in particular saving material and time.
  • the geometry of plastic cover gratings can also be easily implemented, for example by pressing processes.

  • FIG. 2 shows a sectional view of the cover grate according to the invention along the section line II-II from FIG. 1;
  • Fig. 3 is a schematic plan view of an underside of a grating according to the prior art.
  • FIG. 1 shows a top view of an underside 3 of a cover grating 1 according to the invention in one embodiment.
  • Fig. 2 shows a sectional view along the section line II - II from Fig. 1.
  • the cover grate 1 has a walkable and / or drive over top 2 and the bottom 3.
  • the top 2 is formed by a surface 5 of an essentially 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 extend in a direction perpendicular to the direction of extent of the surface 5 of the plane-parallel plate body 4.
  • a large number of drainage openings 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 grate 1 on an upper edge of a channel body, drain box or similar body (not shown) which can be installed in the floor.
  • the support areas 10 are not only one
  • the support sections 9 each run between opposing support areas 10, perpendicular to a longitudinal direction L of the cover grids 1 indicated by an arrow, part of the lower surface 6 of the plane-parallel plate body 4 being visible between the support sections 9 , in which the drainage openings 7 are formed.
  • the support areas 10 of the grating 1 surround narrow sides SE of the drainage openings 7, the support areas 10 and the drainage openings 7 being spaced apart from one another by the plane-parallel plate body 4.
  • two drainage openings 7 are each bordered by two support sections 9, the drainage openings 7 being arranged one below the other perpendicularly to the longitudinal direction L of the cover gratings 1 and of different lengths.
  • further drainage openings 7 can be arranged within two support sections 9, or only one drainage opening 7 is formed. Their arrangement and size can also be varied, for example, depending on the area of use of the cover grate 1. So several small drainage openings 7 can be arranged if with heavy pollution in the area of application, for. B. must be expected through leaves.
  • outer contours 11 of the support structures 8 are flattened in the support areas 10 of the cover grate 1.
  • Material can be saved due to a flattening 13, with wall thicknesses D in the surface direction of the support structures 8 especially in the case of a cast construction with the proportions shown, can be regarded as essentially the same in all areas.
  • the exemplary embodiment shows support areas 10, the outer contour areas 11 of which are essentially wave-shaped.
  • material accumulations 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 areas 10.
  • the support structures 8 accordingly have the same wall thicknesses D in the surface direction in the support areas 10. Due to the uniform wall thickness D, a construction is provided in addition to the material saving, which despite a reduced use of material has a high degree of stability.

A reduced use of materials also lowers the manufacturing and transport costs of the cast components and allows them to be handled more easily.
  • 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 BE of the drainage openings 7, the lower surface 6 of the plate body 4 is visible as a border for the drainage openings 7.
  • the width BE of the drainage openings 7 is thus largely independent of the distance A between the support sections 9, because the width BE is defined by the plate body 4.
  • the support sections 9 can accordingly be designed in accordance with the desired, in particular reduced wall thickness D in the surface direction, in particular in order to achieve material savings here too or to design the wall thicknesses D in such a way that a high stability of the entire support structure 8 is ensured.

Abstract

L'invention concerne une grille de recouvrement conçue pour une rigole d'écoulement des eaux, un avaloir ou des dispositifs d'écoulement des eaux de ruissellement analogues. La grille de recouvrement comprend : une face supérieure praticable et/ou traversable qui est formée par une surface supérieure d'un corps plat à faces sensiblement planes et parallèles ; une pluralité d'ouvertures d'écoulement des eaux qui sont formées dans le corps plat, et ; une face inférieure comportant des structures de soutien sur une surface inférieure du corps plat, lesdites structures de soutien étant reliées au corps plat de façon à ne former qu'une pièce. Ces structures de soutien comportent des sections de soutien entre les ouvertures d'écoulement des eaux et des zones d'appui permettant de disposer la grille de recouvrement sur le bord supérieur d'un corps de rigole, d'une caisse d'évacuation ou d'un corps analogue intégrable dans le sol. Les structures de soutien présentent sensiblement une épaisseur de paroi identique en direction de la surface supérieure, ce qui permet d'améliorer la stabilité tout en réduisant les matériaux utilisés.
