Definitions

  • the present invention relates to a grating and a support frame therefor.
  • Modern gratings such as those used as manhole cover arrangements in streets, must preferably be secured against jumping out when driving over them.
  • a grate is known from DE-GM 72 11578, for example, which consists of two parts which are pressed apart by spring force and thus pressed against their frame.
  • Such a grating is secured against being thrown out when being run over and against theft, but has proven to be disadvantageous with regard to its two-part design and additional buffer elements inserted between the grating and the supporting frame.
  • the present invention is therefore based on the object of providing a grating which can be produced with little technical outlay and is secured against being thrown out when being run over and against theft, and a supporting frame for this.
  • a support frame with two frame parts 2, 2 ', the frame part 2 having an at least approximately elongated recess 3 on the inside into which a guide rib or a projection 4 of the grate engages.
  • the other frame part 2 ' has an elongated recess 3', into which an elongated positive projection of the grating is inserted, in Fig. 1 of this projection only a part formed as a thin tongue-shaped wall 33 is visible.
  • the wall 33 is supported by a base 36 (Fig.1) on the frame part 2 ', but such a base can also be omitted if the weight of the grating only bears on the other parts of the support frame.
  • the grating 1 is provided with inlet slots 5 through which water can flow.
  • the upper part of an inner vertical surface 21 (Fig.2) of the frame part 2 ' has an elongated rounded thickening 22 of the length t, which could also be designed as a knob-like increase.
  • This thickening 22, which is at most up to the upper corner edge of the Extends frame part 2 ' an elongated taper 31 (Fig.3) is assigned to the upper edge 6 (Fig.1) of the grating 1, the length T of the taper 31 being greater than the length t.
  • the thickening 22 of the support frame and the taper 31 of the grating are matched to one another (FIG. 4) in such a way that they form a closure.
  • the grating 1 has on its lower side a narrow slot 32 running parallel to the edge 6, which is arranged so close to the edge of the grating that between this edge and the slot 32 the thin tongue-shaped wall 33 results extends between two incisions running perpendicular to the longitudinal axis of the support elements, only one incision 35 being shown in FIG.
  • the grating also has two concentrically communicating holes 7 and 8, the upper of which has the smaller diameter.
  • the grating with the closure according to FIG. 1 functions as follows:
  • the maximum heights a 'and a ⁇ of the thickening 22 and the thickening 33 with respect to the vertical air gap between the grating and the support frame are approximately the same size, wherein in general a' can be both slightly larger and slightly smaller than a ⁇ .
  • the width a of the Slot 32 must be greater than the height a 'or a ⁇ . 1, the projection 4 is first inserted into the recess 3 of the frame part 2 by the lower part of the wall 33 being supported on the thickening 22. Then the grating on the side where the wall 33 is located is pressed down with great force G (FIG.
  • the support frame can also be provided with a tongue 51.
  • Fig. 5 an example of such an embodiment is shown, in which the tongue 51, which also has a thickening 52 and 62 (Fig.6), is separated by slots 53, 63 and 54, 55 all around from the support frame, so that the Tongue 61 (FIG. 6) is only connected to the supporting frame on its lower side.
  • the grate can in such a case also be provided with a tongue 71 (FIG. 7) or not.
  • 9 shows an embodiment in which the closure 91 is provided on a narrow side of the grating.
  • FIG. 5 Another embodiment of the invention consists in a frame as outlined in FIG. 5, but without slots 53, 54, 55.
  • the grating need not have a taper 31 on the edge 6, but only a thickening 72 (FIG. 7) on the lower part of the tongue 71.
  • the outer walls of the supporting frames are drawn smooth to simplify the figures.
  • the outer parts of the support frame can be provided with depressions, projections, bores and recesses of any kind which serve to anchor the frame.
  • the slot 63 in a version according to FIG. 6 can be connected to bores 64 in order to facilitate washing of the slot 63.
  • the slot 63 can be covered with a form-fitting piece.
  • tongues 33, 51, 61 made from the full material are shown. However, it would also be possible to weld or screw on separate tongues, optionally made of a more elastic material.
  • the tongue-like wall 61 for example, can have a thickened portion 62 (FIG. 6) combined with a depression 65.
  • the grating itself could also be rigid and the movable tongue 51 (FIG. 5) or 61 (FIG. 6) could, as stated, be attached to the frame.
  • the clamping pin 101 shown in FIG. 10 with a tongue-shaped wall 102 and a slot 103 is designed such that it forms a separate closure part which can be inserted into a corresponding recess in a manhole cover 104 in order to form a unit, for example as in FIG. 1 .
  • the advantage of such a clamping pin is that it can be made of a different material that is more suitable for its function than that of the manhole cover.
  • the grating or manhole cover 114 according to FIG. 11, provided with inlet slots 111, 112, 113, has an elongated recess 115 on one of its edges, which communicates with a narrower through-opening 116 on its lower side.
  • the opening 116 and the recess 115 are centered, so that two shoulders or projections 117 and 118 result.
  • the support frame 121 shown partially in section in FIG. 12 likewise has an elongated recess 122 on one of its edges, which is narrower on the upper side thereof Through opening 123 communicates.
  • the opening 123 and the recess 122 are also centered, so that there are also two shoulders or projections 124 and 125.
  • the expansion anchor 131 shown in FIG. 13 is essentially T-shaped, but on the lower part of its vertical leg has two laterally arranged tongues 132 and 133 which are spread upwards.
  • the horizontal bar of the expansion anchor 131 is form-fitting with the recess 115 of the manhole cover 114.
  • the expansion anchor 131 is guided with the vertical leg directed downwards through the recess 115 and the opening 116 loosely and pressed into the opening 123, which is somewhat shorter in length than the opening 116.
  • the expansion anchor is pressed down into the opening 123 so strongly that the tongues 132 and 133 of the wedge-shaped lower part of the expansion anchor 131 are pressed into one another and pass through the opening 123 until they are in the space of the recess 122 thanks to their elastic force expand again so that the expansion anchor 131 remains clamped between the recesses 115 and 122, as is also shown in FIG. 14 using a variant of such an expansion anchor.
  • Notches 134 may optionally be provided on the extensions of the edges of the vertical leg in order to insert a flat plate resting on the tongues 132 or 133 over at least one through a notch 134 led to push rod from above and thus spread the tongues.
  • the working edges of the recesses 115, 122 and openings 116, 123 are parallel to the longitudinal edges of the frame.
  • the expansion anchor in such a way that these working edges form an angle with the longitudinal edges of the frame.
  • the expansion anchor can be round and have the cross section according to FIG. 13 or 14.
  • the clamping pin 151 shown in FIG. 15 with two tongue-shaped walls 152, 153 and a slot 154 is designed in such a way that it forms a separate expansion anchor, which can be pressed into an opening 155 of the support frame 156 designed according to FIG. 1 around a manhole cover 157 to hold.
  • the support frame 161 shown in FIG. 16 has an opening 162, in which the two engagement walls are provided with projections, such as grooves, beads or serrations, which can be horizontal in the longitudinal direction or can have a slight inclination.
  • projections such as grooves, beads or serrations
  • An expansion anchor according to FIG. 13 or 14 hammered in, the tongues 132, 133 of which can optionally be provided with tips in order to be able to better engage in these projections.
  • the expansion anchor shown in FIG. 17 is designed such that the beam 171 extends at least approximately parallel to the tongue edges 172, 173.
  • the support frame 181 shown in FIG. 18 has an opening 182 in which the lower part of the two engagement walls is designed in a stepped manner, the corresponding steps being able to run horizontally in the longitudinal direction or at a small angle with the horizontal.
  • an expansion anchor according to FIG. 17 is optionally also inserted loosely into the opening 182.
  • the expansion anchor is dimensioned such that a flat web 183 can be inserted between it and at least one of the walls of the manhole cover or the supporting frame, in order to press at least one tongue 184 of the expansion anchor down by tapping or pressing, in order to press at least one tip of the tongue in to clamp one of the angular spaces formed by the gradation of the engagement wall and thus to anchor the expansion anchor.
  • the crossbar 191 of the fuse has a T-shaped cross section, the crossbar 191 of the fuse is directed concave downwards in order to achieve a resilient effect.
  • the resilient effect could also be achieved with a ring spring inserted between the crossbar or head of the fuse and its support in the cover can be reached.
  • the fuse can be removed, for example, by demolishing, possibly drilling the central part of the crossbar or head.
