Definitions

  • the invention relates to a stable railway superstructure with a solid carriageway and a method for producing such a superstructure.
  • ballast track In railway technology, a distinction is made between ballast track and slab track, which usually rests on a base made of concrete or asphalt mix.
  • a generic superstructure consisting of multilayer, high-strength asphalt layers and a track arranged thereon with steel sleepers for the rail mounting is shown in the German, magazine ETR (28) 5 - 1979, pp. 437-438.
  • a Y-tie is fastened in the substructure made of asphalt base layers by anchor bolts welded onto a sheet metal, and the height of the sleepers and the rail inclination can be adjusted on the tie using appropriate fastening means for the anchor bolts.
  • the sole of the threshold which consists of parallel H-profiles, is connected to one another by two profile elements arranged in the area under the rail.
  • the joint created by these profiles between the surface of the asphalt base layer and the sole of the sleeper or beyond the lower edge of the sleeper is filled with a special sealing compound.
  • An elastic rubber plate is arranged between the rail and the top of the sleeper, while under the rail itself, which is guided in a ribbed plate, there is again an intermediate layer made of plastic.
  • the welded-on anchor bolt also has the function of stabilizing the track in the desired position through high resistance to lateral forces, transverse displacement forces and forces resulting from rail deflection and lifting the sleeper.
  • the Y sleepers can also be glued to a bearing surface on the underside of the sleepers with a thermoplastic adhesive on an asphalt base layer.
  • DE-OS 19 22 055 it is known from DE-OS 19 22 055 to also support continuous sleepers over their entire surface against the concrete substructure on a thick elastic intermediate layer such that the forces acting on the tracks are transmitted either downwards or to the sides essentially or exclusively by means of an elastic intermediate layer will.
  • the threshold can also be used from the bottom excellent humps are formed, which rests in a recess of the concrete substructure with the interposition of the elastic intermediate layer.
  • This layer should consist of plastic foam or a mixture of bituminous binders, minerals and rubber scrap and / or rubber latex.
  • the sleepers can also consist of steel or wood or plastic and the substructure can also consist of concrete or steel or plastic.
  • the sleepers, the elastic intermediate layer and the substructure can, if necessary, be glued together.
  • the teaching for the person skilled in the art from the invention is the arrangement of an elastic intermediate layer, according to the given representation as uniformly thick as possible, between the threshold and the substructure for damping the vibrations and noises, the corresponding lateral forces and downward forces being transmitted only via this elastic layer .
  • the invention is based on the problem of compensating for the lifting shaft, i.e. forces resulting from the rail deflection, which want to lift the threshold, as well as an inexpensive, quick installation method for all types of sleepers, in particular for, in addition to the lateral displacement forces acting laterally on the sleepers propose light sleepers made of steel or wood or similar materials that can be used in such a superstructure.
  • the pumping effect which can easily be observed in ballast beds and results from a tilting movement of the sleepers, is known from track construction.
  • track construction With today's desired elastic movement of a train over the track, the cause, a deflection of the rails, is inevitable.
  • This is particularly noticeable when the track is made of concrete or asphalt mix on a solid substructure and there are light sleepers, e.g. made of wood, concrete or steel, for example in the form of trough sleepers, sleepers made of H-shaped steel profiles but also Y steel sleepers.
  • the problem is not so serious with concrete sleepers if they are so heavy that the weight forces are higher than the lifting forces.
  • the lifting forces can be, for example, approximately 5 kN when using a UIC 60 rail and a track grate with Y sleepers.
  • this lifting force and the pumping effect largely depend on the type of rail, better its moment of inertia relative to the vertical load, the threshold distance and the threshold weight, the size of the rail on the threshold, the rollover speed of the threshold and the elasticity of the base layer. This means that different types of superstructure would have to be provided for the varying circumstances.
  • the present invention now proposes another universally applicable fastening system for the sleepers on a solid base layer, in which profiles are arranged under the sole of the sleepers, which extend into the base layer and are glued to it.
  • the base layer is preferably coated with a tool e.g. a cutter is grooved at the points where the profiles will later lie.
  • the joint is cut larger than the cross-section of the profiles, for example by at least 20 mm wider, in order to obtain a sufficiently large recess for later grouting of the joint.
  • the grooves are preferably milled into asphalt base layers because the stones present in the base layer are cut and these cut surfaces are intended to serve as adhesive surfaces for the adhesive to be applied.
  • an adhesive surface formed from cement or hydraulically bound inorganic materials is usually sufficient for this, so that a concrete base layer could be produced from the outset with a shaped groove.
  • these adhesive surfaces should not be organic, e.g. Vegetable substances or asphalt or bitumen residues are wetted and also as free of water as possible in order to achieve good adhesion.
  • a flat steel profile to be welded under the sleepers is used as the profile.
  • profiles for example T-profiles, in the groove to provide a further positive and to obtain a positive connection after closing the joint with the adhesive.
  • these profiles can preferably be welded onto steel sleepers, but also without being screwed or riveted or glued without leaving the scope of the invention.
  • the only important thing is the firm connection of the threshold with the profile and its sufficient protrusion from the threshold.
  • the profiles can be cast in with appropriate holders during manufacture or using e.g. Push-through screws are firmly screwed to the threshold.
  • profiles can be used that also serve as spacers for the adjacent H-profiles or double-T profiles that form a Y-threshold and are welded under the sole of the threshold. These also replace spacers which are arranged between the profiles forming the threshold.
  • a pourable, hardening polymer adhesive is preferably used as the adhesive between the profile and the base layer.
  • Such an adhesive is known, for example, under the trade name ICOSIT KC from SIKA-Chemie GmbH, as a potting material, in particular for tram rails.
  • Such a two-component adhesive based on polyurethane or epoxy resin which is to be mixed on site and adjustable by means of appropriate curing agents, has good adhesion both with steel, for example with the profile made of flat steel, and with the rock of the base layer. When fresh, it can be foamed by water or other means. For this reason, the cut surfaces of the joints should be free of organic agents and should not be wetted with water.
  • Adhesives that have a high affinity for concrete or bitumen or other chemical binders, e.g. those that are added to concrete, can also be used as an adhesive if they also provide sufficient adhesion to steel.
  • the sleepers do not have a profile that covers the entire width of the sleepers, but two or more small pieces that are easier to cast around.
  • the profiles may protrude laterally beyond the threshold. If necessary, the steel and / or the joint side surface is provided with a primer for better adhesion.
  • test values presented up to the break were achieved after a very short curing time of a few hours. The result of this is that such a railway superstructure can be produced and used again within one working shift.
  • the superstructure according to the invention can be easily manufactured using essentially the usual techniques in the manufacture of a road, e.g. by applying a base of asphalt mix or concrete. Then high-performance milling machines, such as are used commercially in road construction, can cut grooves in the surface of the substructure, into which the prefabricated sleepers are then inserted in such a way that the profiles get their nominal position as centrally as possible in the previously cut grooves. The profiles are then cast with the adhesive prepared on site, for example the polymer adhesive described above, or commercially available prefabricated containers are used for casting the grooves. If necessary, the sleeper compartments can then be filled with crushed stone or other sound-absorbing agents; At least in the case of an asphalt superstructure, the sun's radiation must be countered by a suitable cover, which can also have a sound-absorbing effect.
  • the schematic figure shows half of the track on average.
  • the railway superstructure consists of a base layer 1 made of asphalt mix, into which grooves 8 have been cut by a milling device.
  • a steel sleeper 2 with welded flat steel profiles 7 is placed on the asphalt base layer 1 with the interposition of a thin compensation film 4 so that the profiles 7 of e.g. 10 mm thick in the middle of the approximately 60 mm wide joint. Due to the inserted leveling foil 4, the sole 9 can lie snugly on the asphalt base layer. Then the joint is cast with polymer adhesive 11, type Sika ICOSIT KC 330-U, so that the threshold is firmly attached to the asphalt base layer 1.
  • the rails 3 can be fastened to the sleepers 2 with commercially available fastening means 5 with the interposition of a base 6 securing the elastic train travel.
  • the sleeper compartments are filled with crushed stone 10, and in order to further increase the transverse displacement resistance, crushed stone can also be arranged in front of the sleeper 2 head.
  • this ballast 10 arranged in front of the head primarily serves for further sound absorption, the vibrations possibly transmitted from the rails 3 to the threshold 2 and the sun protection of the base layer.
