Definitions

  • the invention relates to a method for producing drainage articles for trafficable roads according to the preamble of claim 1 and is intended to simplify and reduce the cost of introducing the damping insert strips.
  • a groove with a trapezoidal cross-section widening downwards is worked into the contact surface and the prefabricated strip of elastomer is then rolled into the groove.
  • the DIN require machining of the groove with narrow tolerances. It is obvious that despite the pre-casting of the groove formed with machining allowances, the machining is very complex and expensive.
  • the machine for rolling in the insert strip is also complicated. Piercing the groove and rolling in the insert strips mean transporting and clamping the workpieces twice.
  • the design of the damping insert does not correspond to the norm, which stipulates that the insert strip must protrude by a certain amount over the surrounding contact surface.
  • the molding tool placed on the support surface via the preferably pre-cast depression can either be open at the top for introducing (and possibly smoothing) the elastomer composition. Alternatively, however, it is also conceivable to make the mold closed at the top and to provide it with pouring and injection openings. In both cases, the top of the cushioning insert can be the final state, i.e. get the right protrusion over the contact surface. However, it is also possible to process the insert to the correct protrusion after curing and to smooth it even further. With this new manufacturing process, both the depression and the surrounding contact surfaces can remain unprocessed. The correct dimension of the overhang is generated by averaging the unprocessed contact surface when aligning the molding tool or during subsequent removal.
  • FIG. 1 Two possible embodiments of the new production method are shown in the figures, specifically in FIG. 1 with a mold open at the top and in FIG. 2 with a mold closed at the top.
  • the frame for a manhole cover is a cast iron frame 1, which is later embedded in a concrete ring.
  • the externally cast-on vertical ribs 2 have shoulders 3, on which reinforcements are placed.
  • the frame has a groove 5 preformed into the support surface 5, into which the insert strip 7 is cast and anchored.
  • a double ring 9, 9 ' is used as the molding tool 8 for the overhang, the inner ring 9 containing a centering 10 which engages over the inner edge of the bearing surface.
  • the elastomer is poured into the gap between the two rings and, if necessary, smoothed out. Depending on the viscosity, filling is also an option.
  • the molding tool 9, 9 ' is lifted off and the insert strip is twisted down to the standard overhang. Only plastic chips are generated, which can be disposed of properly.
  • the molding tool 19 has the profile of an upside-down U.
  • the closed top contains one or more injection openings 21, into which the pourable elastomer is introduced. After lifting the ring shape, only the sprue created at the injection opening needs to be removed.
  • the smooth bottom of the molding tool results in a smooth surface of the insert strip, which does not need to be reworked. Any out-of-roundness of the casting frame is compensated for by the molding tool.
