Definitions

  • the invention relates to a device for fixing rails and / or switch parts to sleepers, using underlay or ribbed plates, in which the underlay or ribbed plates are connected to the sleepers, in particular steel sleepers, with the interposition of electrical insulation, and insulating layers are provided in the area of the fixing of the rib or underlay plates, at least two layers of electrically insulating material being arranged between the threshold and the rib or underlay plate
  • an electrically insulating underlay for railroad rails has become known, an electrically conductive intermediate layer being provided between two insulating underlays below the rail foot in order to be able to determine the insulation state of each individual underlay by measurement.
  • a further line or measuring system must therefore be routed to each individual base, whereby the amount of data to be processed is further increased and the presence of additional conductive layers within the insulation increases the formation of unwanted signals and leakage currents.
  • the invention now aims to provide a device of the type mentioned at the outset with which electrical insulation can be maintained even under unfavorable weather conditions and which furthermore makes it possible, if necessary, to optimize the damping behavior of the fixing of the rail accordingly.
  • the device according to the invention essentially consists in the fact that the superimposed, electrically insulating layers are designed as plates with a different base area, and that the upper, insulating plate facing away from the threshold, preferably the circumference of the underlying insulating plate on all sides, towering over.
  • a particularly effective insulation can be achieved in that the upper, insulating plate facing away from the threshold projects beyond the circumference of the underlying insulating plate, preferably on all sides.
  • an inwardly jumping shoulder edge is formed between the upper plate and the lower plate, on which the formation of a continuous liquid film in heavy downpours is already prevented by gravity.
  • the training can be preferably carried out in such a way that the circumference of the larger insulating plate is designed as a drip edge, as a result of which the circumferential side wall of the lower plate adjacent to the threshold can be kept free from the direct action of rainwater.
  • the training according to the invention has the advantage that it can be used effectively not only in connection with steel sleepers in the superstructure, but that the same components can be used for different sleeper constructions.
  • the same fastening elements can also be used for concrete sleepers, whereby the insulation requirements are naturally not the same as for steel sleepers.
  • the design is advantageously made such that the sleepers have support elements or lugs on at least one narrow side of the base plate and that between the support elements and insulating strips are arranged on the adjacent narrow sides of the underlay or ribbed plate.
  • a particularly stable and reliable insulation in this lateral area of the underlay or ribbed plates can be achieved in that the support elements or lugs from an obtuse angle that is open to the narrow side of the underlay or ribbed plate and that are rigidly connected to one another, in particular rigidly connected to the threshold welded support strips are formed and that the insulating strips as wedge-shaped in plan view Plates are formed, the wedge angle of which essentially corresponds to the obtuse angle between the support strips.
  • the insulation in the area of the screws connecting the underlay plates to the threshold can be carried out in such a way that the screws connecting the underlay or ribbed plates to the threshold are connected to the threshold with the interposition of insulating sleeves and by means of their head side insulating caps are covered, such insulating sleeves must surely prevent direct contact of the screws with the inner edge of the corresponding opening in the base plate or ribbed plate and the upper and lower edge of this opening.
  • the insulation consisting of at least two plates rests, thereby avoiding the risk of a conductive bridge being formed in this area.
  • the formation can be made by preventing leakage currents in such a way that the respective top plate overlaps the edge of the recess of the insulating plate underneath.
  • further protection can be achieved by placing an insulating cap on the outside of the head.
  • FIG. 1 shows a view of a device according to the invention for fixing rails and / or switch parts to sleepers, partly in section; 2 shows a plan view in the direction of arrow II of the design according to FIG. 1, FIG. 1 showing a view in the direction of arrow I of FIG. 2; and FIG. 3 shows an enlarged, partial section through a modified embodiment.
  • a rib plate 4 is fixed on a steel sleeper 1 with the interposition of two plastic intermediate layers 2 and 3, which have electrical insulation properties and damping properties, via screw connections 5 with respect to the sleeper 1.
  • a rail 6 is fastened to the ribbed plate or base plate 4 by means of clamping plates 7, hook screws 8 and double spring washers 9 with the interposition of an elastic plastic intermediate layer 10.
  • the layers 2, 3 of electrically insulating material provided between the threshold 1 and the rib or underlay plate 4 have different base areas, the upper, insulating plate 3 adjacent to the rib plate 4 projecting beyond the circumference of the plate 2 underneath and is designed as a drip edge in order to achieve a safe dripping of a liquid film directly from the insulating layer 3 onto the sleeper 1 without forming a continuous liquid film between the fin plate 4 and the sleeper 1.
  • the screw 5 must be designed in such a way to maintain the insulation between the threshold 1 and the rib plate or base plate 4, for which purpose a bushing 11 is provided which is inserted in the corresponding recess of the rib plate 12 and which is an attachment, for example, as a hook screw 13 with the interposition of a spring ring 14 formed screw on the rib plate or base plate 4 prevented.
  • the screw 13 and the spring ring 14 are thus electrically insulated from the rib plate or base plate 4 by the corresponding design of the bush 11.
  • the screw 13 is covered by an insulating cap 15 after it has been fixed.
  • support elements or bosses 16 are provided with the threshold 1, insulating strips or inserts for maintaining the insulation between the base or rib plate 4 and the threshold 1 17 are provided.
  • the support elements or lugs form an obtuse angle ⁇ with one another, as can be seen particularly clearly in FIG. 2, the insulating strips or insulating inserts 17 being designed as essentially wedge-shaped plates in plan view for reliable maintenance of the insulation are, whose wedge angle corresponds to the obtuse angle ⁇ between the support strips or lugs 16.
  • the additional support elements or lugs 16 serve to absorb sudden forces, such as may occur during machine straightening, via the insulating support elements 17. Furthermore, by appropriate choice of the dimensions of the insulating strips or the insulating elements 17 with uniform components, it is possible to find sufficient length, since an adjustability of the fixing position of the ribbed or underlay plate 4 on the threshold 1 is made possible.
  • the insulating strip 17 can be slotted in the region of the larger insulating layer 3, so that the insulating layer 3 partially engages in the insulating strip 17, as is indicated in FIG. 1.
  • a collar-shaped insulating sleeve 11 is used, in which the spring ring 14 partially immerses.
  • the screw connection is provided for fixing the rib or base plate 4 on a concrete sleeper 18 and the lower, electrically insulating layer 2 is designed in a modified form.
  • a plastic cap can in turn be provided over the screw 14.
  • the fixing of the rail 6 to the ribbed or underlay plate 4 can also be carried out by means of tension clamps and hook screws, with spring clips or with Pandrol clamps, the dimensions and the number of plate screw connections and the damping values of the electrically insulating ones Plastic intermediate layers 2, 3 can be adapted to the respective requirements.
