Definitions

  • the invention relates to a plastic dowel Fastening a rail on a threshold, in particular concrete sleeper, with an essentially cylindrical dowel body that has a head area and has a lower area, at least along a partial length of the lower area has an internal thread Inclusion of a threshold screw and an external thread are provided with which the plastic dowel from the Threshold can be turned out.
  • a plastic dowel of this type is from the German Utility model GM 75 11 808 known. Such a Plastic dowels are used in the railway superstructure to the rails using a sleeper screw on the Fasten threshold.
  • the shape of such Known plastic screw anchor is such that it in terms of its internal thread to the external dimensions a standard threshold screw is adapted.
  • the External thread of the plastic dowel serves the purpose that this can be replaced later.
  • Plastic dowels also for electrical insulation between Threshold screw and threshold.
  • plastic dowels perform higher quality plastic materials, for example made of polypropylene or polyamide.
  • a Another alternative is fiber-reinforced Use plastic matrix material. The above However, materials make them considerably more expensive Production costs of the plastic dowel.
  • Plastic dowels for fastening a rail on a Concrete sleeper known to be essentially one has cylindrical dowel body.
  • This dowel body has a threadless head area and a lower area.
  • an essentially constant Wall thickness trained lower area are one Internal thread for receiving a threshold screw and a External thread provided, through which the dowel in the Threshold can be screwed in.
  • the wall thickness of the anchor is chosen so that the ratio of inside to Outside diameter of the known dowel in the range of 1.3 lies.
  • the dowel known from GB-A-865,120 also enables electrical insulation of the sleeper screw towards the threshold.
  • there is a problem in danger of the screw being screwed in cuts the thin wall of the dowel. About the Cut surfaces moisture penetrating into the dowel can destroy the isolating effect.
  • the object of the invention is based on the prior art explained above reasonable cost to produce plastic dowels to create the type described above, in which the Risk of its destruction when screwing on Minimum is reduced and at the same time one sufficient stability of the screw-dowel connection guaranteed.
  • a plastic dowel to attach a rail a threshold, in particular a concrete threshold which with a substantially cylindrical Dowel body is equipped with a threadless head area and has a lower area, at least along a partial length of the lower area has an internal thread Inclusion of a threshold screw and an external thread are provided with which the plastic dowel from the Threshold can be unscrewed
  • the lower area of the Anchor body one to the external thread of the Sleeper screw conformed shape of essentially has uniform wall thickness
  • the wall thickness the anchor body is dimensioned so that the Dowel outer diameter at least 1.05 times and at most 1.2 times the inner diameter of the dowel is and with the lower region of the dowel body a rounded external thread of a sleeper screw is adjusted.
  • the Dowel body the screw in the manner of a thin-walled Skin.
  • the wall thickness of the plastic dowel for example for a sleeper screw with a Nominal diameter of 24 mm, 0.8 to 2 mm.
  • the plastic dowel shown in Fig. 1 consists of a Plastic anchor body 1, which is a threadless Head region 1a and a lower region 1b, in both an external thread and an internal thread is trained.
  • the head area 1a opens at the top of the Plastic dowel with a threshold screw 2 is rotatable, which in Fig. 1 and 4 in the Plastic dowel 1 screwed state shown is.
  • the lower area 1b of the Dowel body designed so that it with even Wall thickness of the external thread 2a of the sleeper screw 2 envelops.
  • the one formed in the lower area 1b serves by wrapping the sleeper screw with uniform wall thickness resulting in that the plastic dowel - for example to his Replace - can be turned out of the threshold.
  • Fig. 2 shows the section through a conventional Sleeper screw.
  • FIG. 4 shows the adapted one as section B from FIG. 1 Design of dowel body 1 and screw 2 in the area the wrapping.
  • the dowel body according to the invention By designing the dowel body according to the invention the forces from the threshold screw over the Transfer plastic dowels to the concrete sleeper without that there is an exceedance of the permissible Yield stresses in the plastic material comes. Much more the thinness of the wall results in a more direct Contact between the parts to be connected without the electrical isolation effect canceled between the two becomes. It is advantageous that the lower region of the Anchor body to the rounded external thread of the Threshold screw is adjusted. This will make the danger cutting into the thin dowel wall when screwing in the screw compared to the sharp-edged thread avoided.
