Definitions

  • the invention relates to a grating for a drainage channel according to the preamble of claim 1.
  • Drainage channels provided with grating of the type mentioned above are used primarily in road construction. If such cover gratings are placed loosely on the drainage channel, they can be lifted off the surface by vehicles traveling over them, which is undesirable for reasons of traffic safety.
  • a known cover grating is fastened to a cast frame held on the drainage channel by means of screws.
  • the frame serving as a base for the cover grate has transverse webs and screw cross members which hinder the cleaning of the drainage channels even after the cover grate has been removed.
  • the known arrangement is also economically disadvantageous since the cast iron frames are expensive and two different cover grids, one for the first phase and another for the final phase, have to be used when installing the road surface covering in two phases.
  • the object of the present invention is therefore to attach the cover grate to the base in such a way that it is held there to a degree that ensures traffic safety, but at the same time can be removed easily if necessary or, in other words, to design the cover grate and base in such a way that the former is held onto the latter without additional fastening means.
  • a self-actuating fastening system which, after the covering grille has been correctly placed on it, holds the latter securely in the desired position without additional measures and releases it from this position without loosening any fastening elements.
  • This fastening system is also built into the existing elements of the drainage system in such a way that it is auto matically supplied and the attachment is easily created as a by-product when the cover grille is placed on. Consequently, the invention also simplifies storage and assembly or disassembly, which has corresponding economic advantages.
  • the acute and obtuse angles are essentially complementary, i.e. their sum is theoretically 180 °. In practice, however, this value varies depending on the tolerances used.
  • the base which has the multiple length of a cover grating, has alternating along a long side in acute and obtuse contact and guide surfaces, the angle remaining constant over a distance corresponding to the length of the cover grate.
  • This embodiment has the effect that the positive engagement with successive cover grids changes from one to the other longitudinal side, a stop against movement of the cover grids relative to the base in the longitudinal direction being created at the point of the angle change.
  • the ends of the cover gratings are advantageously provided with recesses or protrusions at their ends such that these element parts engage in one another and thereby result in an additional fixation of the cover gratings.
  • the cover gratings can rest directly on the drainage channel, so that the latter forms the base, or a further base element can be provided between the cover grill and the drainage channel. Since the same covering grate according to the invention is inserted in both cases, it is suitable both for single-phase installation and when the end covering is applied at a later time Time is given for the two-phase installation. The invention therefore simplifies the two-phase installation, since different gratings do not have to be used for each phase, as in the known cover grating.
  • the cover grille 1 in FIGS. 1 to 3 has continuous recesses 2 and webs 3 tapering downward between the recesses.
  • the two long sides 4 and 5 of the cover grate 1 are of stepped design, so that the cover grate tapers downward.
  • Each step is formed by a horizontal support surface 6, 7, 8, 9 and a guide surface 11, 12, 13, 14.
  • the one upper contact surface 6 meets the one upper guide surface 11 at an obtuse angle a and the other upper contact surface 7 meets the other guide surface 12 at an acute angle ⁇ .
  • the lower contact surfaces 8, 9 meet at right angles with the corresponding guide surfaces 13, 14.
  • the cover grate 1 has a transverse elongated recess 16 and at its other end 17 a projection 18 of the same type.
  • the recess 16 and the projection 18 extend over part of the thickness of the cover grate 1.
  • the recess 16 is intended to receive the projection 18 of the following cover grate, so that both together provide additional security against the lifting and the relative movement of the cover grids against one another .
  • the side walls 21, 22 of the drainage channel 23 shown in FIGS. 4 to 6 with a U-shaped cross section have stepped ends 24, 25, each with a horizontal end surface 26, 27 and a horizontal one Contact surface 28, 29.
  • the latter are intended for placing the lower support surfaces 8, 9 of the cover grate 1 or a further support element.
  • the end surfaces 26, 27 are connected to the contact surfaces 28, 29 via guide surfaces 31, 32.
  • One guide surface 31 forms an obtuse angle with the corresponding contact surface 28 and the other guide surface 32 forms an acute angle with the corresponding contact surface 29.
  • Obtuse and acute angles a 'and ⁇ ' correspond to the obtuse and acute angles a and ⁇ of the cover grate 1.
  • the acute angle ⁇ 'between the support surface 28 and the guide surface 31 changes to an obtuse angle ⁇ ' or the obtuse angle to an acute angle, so that the cover grids alternate with their along the respective side wall 21, 22 of the drainage channel 23 rest on acute-angled or obtuse-angled long side (4,5).
  • This change in angle is indicated in FIGS. 5 and 6 by dashed lines.
  • At the location of the angle change there is a stop at the ends 24 and 25 of the side walls 21, 22 of the drainage channel 23 which counteracts a movement of the cover grids 1 in the longitudinal direction.
  • the arrangement shown in FIGS. 4 to 6, in which the drainage channel 23 forms the base for the cover grate 1, can either be in the single-phase process or in the first phase of a two-phase process.
  • the cover grating arranged in the first phase is removed at a later time, another element serving as a base is placed on the drainage channel and the cover grate is arranged on this new base.
  • Such a sub to be arranged in the second phase of the two-phase installation Layer can be of two individual elements, as they are shown as rulers 34, 35 in FIGS. 7 to 10.
  • the rulers are constructed in the same way as the two long sides 4, 5 of the cover grate 1, that is to say step-like, and have corresponding horizontal upper and lower contact surfaces 6 ', 7', 8 ', 9' and upper and lower guide surfaces 11 ', 12 ', 13', 14 'on.
  • a base is formed in each case by two rulers 34, 35 arranged in parallel, a ruler part with an obtuse angle being opposed to one with an acute angle (FIGS. 9, 10).
  • the rulers at their ends 37, 38 have 36 recesses 39, 41 on their inner side, which come to lie opposite one another in the case of rulers arranged in parallel and serve to accommodate connecting rods during assembly.
  • These connecting rods, not shown, can easily be removed after the rulers have been attached to the recesses which are open at the top.
  • the rulers can be connected to form a permanent unit by means of webs.
  • the rulers 34, 35 On its outside 42, the rulers 34, 35 have recesses 43 running in the longitudinal direction, into which the useful covering material, e.g. Asphalt, penetrates and holds the rulers 34, 35 from the outside after solidification. This interaction of asphalt 44 and rulers 34, 35 is shown in FIG. 11.
  • the useful covering material e.g. Asphalt
  • Cast-iron rulers 34, 35 also lie on the steel frames on both side walls designed support and guide surfaces (6 '- 14'). These rulers 34, 35 form the base for the cast iron covering grille 1 shown in detail in FIGS. 1 to 3.
  • the stops formed by changing the obtuse to the acute angle on the inside of the rulers are shown by dashed lines.
