Definitions

  • the invention relates to a fastening for a track plate and a method for producing a switch and a Y-shaped steel sleeper for a railway according to the preambles of claims 1, 6 and 8.
  • Track plates are fastened, for example, as ribbed plates or sliding chairs for rail mounting on wooden sleepers (DE-C-35 26 653) or concrete sleepers with wood screws directly or in corresponding dowels.
  • CH-C-396960 shows the mounting of a track plate on a steel or concrete bridge with the interposition of an insulating plate. Eccentric insulating bushes are inserted into the holes in the track plate, which are intended to correct inaccuracies in the arrangement of the bolts for fastening the track plates or to allow the track width or the lines of the rails to be readjusted.
  • the insulating bushes which are provided with an eccentric hole and are loosely inserted into the ribbed plate, are to allow precise positioning of the rails by being supported on the fastening bolts.
  • the type of attachment leads to partial destruction of the insulating plate in the area of the load Holes in the ribbed plate and to a bending load on the fastening bolt.
  • Track plates for Y-steel sleepers are still used today as connectors for the upper chords of the adjacent double-T beams and welded to them (DE magazine “ETR Eisenbahntechnische Rundschau", issue 1-2, 1988, pp. 67-70 and DE-U -87 09 429.0).
  • the track plates must be welded all around and from the underside of the sleeper. When producing individual sleepers, these have to be turned. The production of a turnout from Y-steel sleepers with such track plates is even more difficult.
  • the track plates with the rails on them are first welded on one side and then the entire switch or the part of a switch that is ready to be installed must be turned to weld the track plates from the underside. Overhead welding is prohibited for reasons of space, visibility and safety.
  • the disadvantages of the prior art should be avoided.
  • the object is first achieved according to the invention by fastening a track plate on Y-shaped steel sleepers for a railway consisting of double-T beams, a track plate with holes into which insulating bushings are fitted being used.
  • Bolts are attached to the double T-beams by stud welding to accommodate the track plate and an insulating plate with large passages for the screw bolts arranged between the track plate and the Y-steel sleepers.
  • the inventive use of the stud welding at the previously determined fastening points enables defined defined bead sizes due to the standard use of the conventional weld bead-forming ceramic rings and the resulting bead size Burn-in conditions during welding.
  • the method allows series production of the fastening according to the invention. Problems with welding spatter as usual with manual welding are excluded with the mentioned stud welding technology.
  • the actual rail fastening no longer requires electrical insulation, so that commercially available, non-insulated or isolatable fastening of rails to ribbed plates by means of hook screws and conventional K fastening or resilient fastening can be used.
  • the insulating plate for example made of cellular plastic material, can also be assigned a resilient effect for the elastic fastening of the rib plate.
  • This spring action is used in particular for asphalt or concrete bedding of the tracks, in which the elastic behavior of the track body is simulated by a depression characteristic of an insulating plate made of plastic, which is similar to ballast bedding.
  • the plastic thicknesses and material stiffnesses to be specified can be calculated exactly, as practical tests have shown.
  • the insulating bush has a bore which is, for example, 1 to 10% larger than the diameter of the shaft of the screw bolt and is made of a hard plastic.
  • a stabilized insulating sleeve for. B. made of glass fiber reinforced polyamide, remains true to shape with the occurring mechanical loads and temperatures.
  • the definition of the socket size causes easy insertion of the ribbed plate with the bushing and the prevention of the introduction of a bending moment on the screw shanks in the event of a transverse displacement of the track plate resulting from the load on the rails. In extensive tests, it was found that this transverse displacement in the fastening according to the invention can be limited to 0.1 to 0.3 mm even after several million load cycles. This allows a close tolerance of the bush geometry.
  • the welding point of the bolt on the threshold is provided with permanent corrosion protection, e.g. B. from a bitumen material or a special epoxy resin mixture, which is set soft for the usual temperature load on rails from -40 ° C to + 80 ° C. This prevents corrosion media from attacking the weld.
  • the insulating plates are equipped according to the invention with large passages which, according to the hole cross sections, can accommodate a defined mass of corrosion protection agent.
  • This feather serves several purposes.
  • a desired sinking depth of the insulating plate under load can be increased by using a spring or made more secure without the Screwing is loosened.
  • the tightening torque of the screw connection can be metered more sensitively.
  • a plastic cap is provided, which indicate a certain travel, in which the cap rests on its base.
  • This process allows the series production of Y-steel sleepers with ribbed plates of commercially available type to be installed, in particular considerably increased, in particular if a coordinate welding machine is used for stud welding.
  • This is understood to mean a machine that - controlled by hand or by computer - any one Approach coordinate on a threshold or switch, relative to a spatially fixed reference point. It is no longer necessary to align the threshold correctly in a switch for assembly.
  • the fastening point of the screw bolts can be determined manually or by computerized calculation and control of the welding machines, and a stud welding device can be applied precisely. As a result, there is no need for intermediate assembly and subsequent partial disassembly to remove the switch. This also avoids turning the finished switch or individual threshold for the final welding of the rear sides of the ribbed track plates.
  • sleeper head or sleeper end can be used as a reference point for a bolt, since, unlike the wooden sleeper or concrete sleeper, the steel sleeper can be manufactured with constant dimensions as standard.
  • separately manufactured Y-steel sleepers can be connected to a turnout with a separately manufactured carriageway on the construction site or, if necessary, in a partial assembly workshop.
  • the threshold can be prefabricated with stable spacers between the top and bottom chords of the double-T beams. These are particularly adapted to the beams and their loads, since the ribbed plate welded on according to the prior art is omitted as a spacer and as a stiffening component. Depending on the width of the belts or the width of the beams used or their moment of resistance or inertia or the width of the track plates, the beams can also be welded to the belts without gaps.
  • the sleepers can be designed in Y shape or in double Y shape, half Y shape or in a so-called Y-N shape.
  • Figure 1 shows a track system with rails 11, 13, which are in track S along the track axis A and from a track with YN sleepers 1200 into a switch consisting of sleepers 1201 to 1207.
  • the switch has additional tongue rails 14, 15; it has a radius R of 1200 m.
  • the threshold 1200 consists in principle, similar to the other sleepers, of a middle double T-beam 2, two outer double T-beams 1 and short double T-beams 4 in between.
  • Each two beam ends 1, 2 and 1, 4 form one Rail base P3, which is designed as a ribbed plate or base P7, which is designed as a sliding chair.
  • the thresholds 1201 to 1207 of the switch section between the dividing points 8 are designed similarly to the threshold 1200, except that the rail support points take into account the tongue rails 14, 15 and their displacement are trained differently.
  • the tongue rails 14, 15 can be moved by rods 10 between the stops 9.
  • track width S, track axis A, turnout radius R and predetermined base point spacing for known Y-steel sleeper dimensions, starting from the reference axis X, the positions of the base points P3, P7, the z. B. can be calculated in a computer and transferred to a corresponding coordinate grid in a partial assembly plant for the switch section 8-8.
  • FIG. 2 shows a fastening as it is provided for a Y-steel sleeper switch 12 on a solid carriageway, for example asphalt bedding or concrete bedding.
  • the attachment 49 shown on the left in FIG. 2 is on the threshold 1200 in the example the double-T beam 2, while the cut fastening shown in the right half lies on the double-T beam 1 in the sense of the threshold 1200.
  • the hook screws 17 with springs 18 for fastening the foot 23 of the rail 16 lie centrally between the supports 1, 2; they are anchored in a recess in the rib 25 of the rib plate 3.
  • a damping plate 24 is arranged between the rail 16 and the rib plate 3.
  • the ribs 25 of the rib plate 3 limit the lateral migration of the rail foot 23.
  • Two plastic plates 19, 20 are arranged between the rib plate and the double-T beam consisting of the upper flange 22, lower flange 21 and web 5. These simulate a desired sink depth of a threshold - that is, an elastic behavior - when the rail 16 is loaded by a train.
  • a screw bolt 36 was firmly connected to the shaft 27 to form a welding bead 28 with the upper flange 22 of the double T-beam 1.
  • the welding point is filled up to approximately the thickness of the insulating plate 20 within the passage 29 of this insulating plate with anti-corrosion agent 26 to cover the welding bead 28.
  • the screw shaft 27 is surrounded by an insulating bush 31 fitted tightly in hole 30 of the rib plate 3, the collar of which on the rib plate 3 rests.
  • a disc spring assembly 34 is arranged between two disks 32 and is surrounded by a spring cap 33. Above the spring cap 33, a further washer is arranged on the screw bolt 36, which transmits its force to a spring assembly 34 by a self-locking nut 35 until the spring cap 33 rests on the insulating bush 31 is coming. In this way, a pre-adjustable spring travel is visibly achieved from the outside.
  • the screw bolt is provided with a cap 37 which contains condensation water openings 48.
  • Figure 3 shows a fastening of a ribbed plate similar to Figure 2, but as a fastening for a steel sleeper in ballast bedding.
  • the fastening 50 shown on the left belongs to a double T-beam 2 lying behind the double-T beam 1, while the fastening cut in the right-hand illustration belongs to the double-T beam 1.
  • the same numbering of the parts shows their identity.
  • a short screw bolt 39 is welded onto the top flange 22 of the double T-beam 1;
  • An epoxy resin 45 has been introduced as a corrosion protection agent around the welding point in passage 46 of an insulating plate 44.
  • the bolt 39 protrudes through an insulating bush 43 which is tightly inserted in hole 30 of the ribbed plate 3.
  • washers 41, 42 are provided which press the collar of the insulating bush 43 firmly onto the ribbed plate 3.
  • the screw bolt 39 is provided with a cap 38 which has condensation water openings 47.
  • a ribbed plate fastening corresponding to the situation in FIG. 3 was subjected to a fatigue strength test in a scissor lever vibration test.
  • the sleeper consisted of two wide-flanged double T-beams in parallel in the support area of the rail with a profile height of 95 mm and a width of the belts of 140 mm, which were welded together at a distance of 20 mm.
  • the spacers between the upper and lower belts were welded in between the upper and lower belts 100 mm below the area of the ribbed plate.
  • four bolts 39 for each rib plate with the thread M22 were welded onto the upper flange 22 of the double-T beam 1.
  • An insulating plate 44 and then the rib plate 3 were first pushed over the screw bolts 39.
  • the insulating plate was 8.5 mm thick and consisted of ethylene-vinyl acetate copolymer (EVA). Between bolt 39 and ribbed plates 3, an insulating bush made of polyamide with 30% glass fiber reinforcement was arranged in hole 30, which had 1 mm play with the bolt.
  • the disks 41 were designed as spring washers; with the tightening torque of 250 Nm that was exerted on the nut, they pressed the insulating bush onto the ribbed plate and thus onto the top of the threshold.
  • Type UIC 60 was tested as a rail.
