Definitions

  • the invention relates to a polygonal, in particular rectangular frame for manhole covers, which is composed of a plurality of frame parts running along the frame side, on which support and / or inclined sealing surfaces for a cover are formed, at least two frame parts lying opposite one another being of identical design.
  • the invention has for its object to design the frame parts for frames for manhole covers of the type mentioned so that frames can be assembled with the same frame parts that can accommodate lids with two different insertion depths.
  • This object is achieved in that the opposite pair of frame parts after turning through 180 ° about an axis parallel to the frame plane (X) is interchangeable and that the other opposite pair of frame parts after turning through 180 ° around the frame plane parallel axis (Y) and rotation about an axis perpendicular to the frame plane (Z) is interchangeable.
  • the frame shown in Fig. 1-4 is rectangular and composed of four frame parts 1, 2, 3.4, which are screwed together at the corners. These frame parts have smooth sealing surfaces 11, 12, 13, 14 on the inside of the frame. These sealing surfaces are inclined relative to the frame plane (XY plane in FIG. 4), specifically the sealing surfaces 11, 12 and 14 have an outward or upward inclination, while the sealing surface 13 is inclined inward or downward, that is to say undercut is.
  • the sealing surfaces 11 and 13 run parallel to one another, the sealing surfaces 12 and 14 diverge upwards.
  • These sealing surfaces interact with the equally inclined lateral abutting surfaces of a cover (not shown) which can be inserted into the frame, engaging under the sealing surface 13.
  • the frame parts 2 and 4 also have inwardly projecting flanges to form a respective support surface 22, 24 which runs parallel to the frame plane and on which the cover can rest.
  • the frame parts 1, 2, 3, 4 manufactured with a small undersize are first loosely screwed together, then the cover is placed on the bearing surfaces 22, 24 and then the screw connection of the frame parts is tightened until the sealing surfaces 1, 12, 13, 14 fit tightly against the side abutting surfaces of the cover.
  • a sealing compound which then solidifies, can be inserted into the butt joints between the frame parts at the frame corners.
  • the opposite frames parts 1 and 3 have an identical shape, and also the frame parts 2 and 4.
  • the frame part 3 is rotated relative to the frame part 1 by 180 ° with respect to an axis which runs parallel to the frame plane and parallel to the longitudinal center line of the frame part 1 or 3, ie about an axis parallel to the X axis indicated in FIG. 4.
  • the sealing surfaces 11, 13 reach the desired parallel arrangement.
  • These frame parts 1 and 3 have no support surfaces for the lid.
  • the frame part 2 has not only an inwardly projecting flange which forms the support surface 22, but also an outwardly projecting flange which forms a further support surface 22 '.
  • the frame part 4 is rotated relative to the frame part 2 by 180 ° with respect to an axis which runs parallel to the frame plane and perpendicular to the longitudinal center line of the frame part 2 or 4, that is to say about a parallel to the specified X axis Axis.
  • the frame parts 2 and 4 are provided with flanges 8, 9 projecting at right angles, which are also inclined to the frame plane (X-Y plane), so that they abut the inclined frame parts 1, 3.
  • the flanges 8, 9 do not extend over the entire height of the frame parts 2, 4, but rather leave the space required for supporting the cover above the support surfaces 22, 24 or below the support surfaces 22 ', 24'.
  • any stiffening ribs 16, 17 of the frame parts 2 and 4 which are also arranged on both sides, but not continuously over the entire height.
  • frame parts 1, 3 have stiffening ribs 18, 19 only on one side, the perpendicular ribs 19 being able to pass over the entire height.
  • frame parts 1 and 3 have no flanges. To produce the frame parts 1, 3, therefore, only corresponding pieces need to be cut off from a longer profile strip and provided with bores for receiving the screws for the corner screw connection.
  • FIG. 5 differs from that of FIG. 4 only in that the support surfaces 22, 24 are placed lower, so that the distance of the support surfaces 22, 24 from the upper edge of the frame parts 2, 4 is greater than the distance of the (In this installation position not required) support surfaces 22 ', 24' from the lower edge of the frame parts 2,4.
  • the frame parts 2, 4 are therefore mirror-symmetrical to one another with respect to the axis Y, but are no longer identical. If the frame parts 2, 4 are rotated by 180 ° with respect to the axis X and then exchanged with one another, then the support surfaces 22 ', 24' come into the operating position on the inside of the frame and can then serve as support surfaces for a cover with a lower insertion depth.
