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 mostly 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 means of anchor bolts welded onto a sheet metal by the height of the sleepers and the rail inclination
- the joint between the surface of the asphalt base course and the sole of the sleeper or beyond the lower edge of the sleeper is filled with a special pouring compound.
- An elastic rubber plate is arranged between the rail and the upper side of the sleeper, while an intermediate layer made of plastic is arranged under the rail itself, which is guided in a ribbed plate.
- the welded-on anchor bolt also has the function of stabilizing the track in the desired position against lateral forces, transverse displacement forces and against forces which result from the rail bending and lift off the sleeper.
- the Y sleepers can also be bonded to a thermoplastic adhesive on an asphalt base layer on their contact surface on the underside of the sleepers.
- the sleepers can also consist of steel or wood or plastic and the substructure can also consist of concrete or steel or plastic. Furthermore, it is optionally stated that the sleepers, the elastic intermediate layer and the substructure can, if necessary, be glued together.
- the lesson for the person skilled in the art from the invention is the arrangement of an elastic intermediate layer, as thick as possible according to the illustration given, between the threshold and substructure for damping the vibrations and noises, the corresponding lateral forces and downward forces only via this elastic layer be transmitted.
- the invention is based on the problem of compensating not only for the lateral displacement forces acting laterally on the sleepers, but also the lifting shaft, ie forces resulting from the rail deflection which want to lift the sleepers, and an inexpensive, rapid laying method for all types of sleepers , especially for light sleepers made of steel or wood or similar materials, which can be used in such a structure.
- the problems are solved according to the invention by claims 1 and 8.
- Advantageous further developments of the invention are specified in the subclaims.
- 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 support on the threshold, the rollover speed of the threshold and the elasticity of the base layer. This means that different designs of the superstructure 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 generally 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 which also serve as spacers for the adjacent H-profiles or double-T profiles which form a Y-threshold and which 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 can be viewed on site and is adjustable by means of appropriate hardening agents, has good adhesion both with steel, for example with the profile made of flat steel, and with the rock of the base layer. In the fresh state 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, for example those that are added to concrete have, can also be used as an adhesive if they also provide sufficient adhesion to steel.
- the sleepers are not fitted with 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.
- the superstructure according to the invention can be easily manufactured using essentially the usual techniques for the manufacture of a road, e.g. by applying an asphalt mix or concrete surface. Then powerful milling machines, such as are used commercially in road construction, can cut grooves into the surface of the substructure, into which the prefabricated sleepers are then inserted so that the profiles get their desired position as centrally as possible in the previously cut grooves. The profiles are then cast with the adhesive prepared on site, for example the previously described polymer adhesive, or commercially available prefabricated containers are used for casting the grooves. If necessary, the sleeper compartments can then be filled with ballast 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 invention will be explained in more detail with the aid of the schematic sketch.
- 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 compensating film 4 so that the profiles 7 are, for example, 10 mm thick in the middle in the approximately 60 mm wide joint. Due to the inserted leveling foil 4, the sole 9 can lie snugly on the asphalt base layer.
- the joint is cast with polymer adhesive 11, type Sika ICOSIT KC 330-U, so that the threshold is permanently connected 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 ballast 10, and to further increase the transverse displacement resistance, ballast can also be arranged in front of the sleepers 2.
- 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.
