Definitions

  • the invention relates to a positionally stable track body and the use of prefabricated concrete parts for this track body.
  • German Patents 39 01 347 and 43 28 668 respectively, to place the concrete sleepers in a concrete trough and then to fill the compartments between the sleepers with concrete or to press the concrete sleepers into the fresh in-situ concrete.
  • Threshold is temporarily attached to the base layer using a polyurethane adhesive before the concrete is then leveled in the threshold areas. Dismantling of such sleepers cast in place concrete in place concrete is associated, for example in the case of derailments or line conversions, with the previous destruction of the entire track body.
  • a generic track body is known from EP-A 0 546 380, in which a track grid consisting of cross sleepers and rails is laid on a flat base layer with the interposition of an elastic intermediate layer.
  • the sleepers - obviously made of concrete - are evenly trapezoidal in cross-section.
  • Intermediate bodies with a trapezoidal cross section are arranged between the threshold ends projecting beyond the rail, wedges made of elastic material, preferably polyurethane, being placed on the outside in the joint between the threshold ends and the intermediate bodies before the intermediate bodies are used. Then the intermediate body with the help of a Screw is screwed onto the fixed support plate and thus the sleepers are pulled against the support plate with force via the elastic plastic wedges.
  • the track body thus has an indirect positive fit with the support plate through the intermediate body.
  • DE 40 41 237 A1 discloses prefabricated precast concrete parts, for example made of single-grain material, for use as counterweights to lifting forces which act on sleepers, the concrete parts being able to be placed on the sleepers between the rails and the sleeper heads. These counterweights can also have a sound-absorbing surface structure.
  • DE 38 27 547 A1 discloses sound-absorbing panels made of aggregate concrete with a superficial reef structure, produced as prefabricated concrete parts that can be placed on the outside of the rails on the sleepers.
  • precast concrete parts made of single-grain concrete should be provided with profiles on the surface for sound insulation and for water drainage on the underside. These prefabricated components are placed in the sleeper compartments and secured against change of position with the substructure made of reinforced concrete, for example by casting with concrete, synthetic resin mortar, permanently elastic plastic or the like.
  • Airborne noise which originates from the weakest part of the rail, the web, remains an unsolved problem.
  • a number of systems have been published for sound insulation on permanent roads. From the German magazine “ETR Eisenbahntechnische Rundschau", Hestra-Verlag, Darmstadt, 1995, Issue 7/8, pages 559-565 as well as from DE-Offenlegungsschriften 44 17 402 and 44 37 826 Sound absorber elements known for solid roadways, which consist of aggregate concrete, cement-bonded expanded clay or resin-bonded foam glass, optionally with a covering. These absorber elements stand next to the sleepers or rest on them, between the rails and / or on the sleepers heads.
  • these absorber elements can also be provided with beads, as are known in particular from DE utility models 295 13 062 and 295 15 497. These beads can extend to below the top edge of the rail in the middle of the track or can also protrude above the top edge of the rail. Systems are not disclosed which, in addition to airborne sound insulation or structure-borne sound insulation, also contribute to stiffening the track body.
  • the invention is based on the problem of proposing a positionally stable track grate, the manufacture of which is as simple as possible, without the use of clamps with the fixed support plate under the track grate.
  • a second goal is to reduce the noise emission in such solid carriageways, which in principle have a higher sound radiation than tracks in the ballast bed.
  • a solid base for example a hydraulically bound base layer on an earth level
  • a concrete base plate or poured a corresponding asphalt base layer may be produced with a drainage mat and at least on top of it arranged a concrete base plate or poured a corresponding asphalt base layer.
  • concrete supporting slabs can also be designed as precast slabs or in-situ concrete with a small thickness combined with an asphalt concrete or an asphalt leveling layer as a solid supporting slab. It does not matter whether this support plate is reinforced or unreinforced.
  • cross sleepers here preferably concrete cross sleepers
  • the rails can be fixed on it or preassembled track yokes are placed on the support plate and become one Endless strand connected by welding the rails.
  • the support plate is so flat and the tolerance of the sleepers so low that no further adjustment work is required.
  • at least the rail has to be aligned sideways and the rail is usually leveled by appropriately relining the rail support.
  • intermediate bodies are placed in the middle of the sleeper area, which are adapted in the manufacturer's plant to the sleeper compartment width and the possibly curved or otherwise deviating, eg waisted sleeper shape.
  • more or less wide joints form adjacent outer sides of the sleepers between the intermediate body and the direction of the track. These joints are foamed in the final step. If necessary, the installation sequences of sleepers and intermediate bodies can also be changed and some or all intermediate bodies can be placed first.
  • assembly foam for example polyurethane foam
  • foam can be used as foam, as is constantly used in construction technology, for example when inserting doors or windows in building construction.
  • a commercially available bottle of 3/4 l is sufficient to fix about 50 intermediate bodies in the sleeper compartments. It is assumed that the intermediate body do not cover the area of the rail fastening, but leave this part of the sleeper compartment free, in order to be able to check and, if necessary, dismantle the rail mounting with conventional construction machinery.
  • such an intermediate body has been produced in one piece, wherein it is shaped in the middle of the track in accordance with the threshold thickness and rises towards the rail to a level of approximately 5 to 40 mm below the upper edge of the rail.
  • the thickness of the intermediate body should even be slightly below the corresponding threshold thickness, so that, on the one hand, an electrical conductor can be placed on the sleepers and, on the other hand, a rail for later installation in the middle of the track can also be placed without the intermediate body damaging or stressing and thus introducing impermissible loads into the foamed joint.
  • the tang formed on the rail side should not protrude above the top edge of the rail, so that an earth fault to the rail is possible when the overhead cables fall down.
  • the top edge of the rail must remain free towards the middle of the track so that snow flying can be started.
  • Such a bead towards the rail side is able to reflect sound emission from the rail web, the main source of noise, or to partially absorb it with a suitable choice of material.
  • Single-grain concrete which has large pores and is permeable to water, is preferably used as the material for the intermediate body.
  • other materials known per se can also be used for the intermediate bodies according to the invention.
  • Such a stiffened track grate in particular if cross sleepers made of concrete and intermediate bodies made of concrete are used, has a total weight which leads to such a high coefficient of friction that a lateral shifting of the track grate appears impossible due to the frictional forces alone.
  • the coefficient of friction can be increased by elastic, soft plastic parts to be arranged under the sole of the threshold and / or the intermediate body.
  • the deformable plastic By the deformable plastic also a full support and a sound decoupling from the base layer is achieved. Since the threshold and the intermediate body lie equally on the solid base layer and are elastically connected to each other by the expansion of the joint, no differential movement with regard to the sinking is to be expected under operational stress. Any torsions in the millimeter range can be easily absorbed by the elastic foam.
  • additional shaped bodies made of the same material as the intermediate bodies can also be arranged in front of the sleepers, the sleeper compartments and partially or completely bridging the sleeper ends and covering the sleeper ends, in which they are also placed between the sleepers on the asphalt base layer.
  • the joints on the sleeper compartment or, if necessary, all joints at the sleeper end can also be sprayed with the aforementioned foam. Even if torsional forces, ie a different longitudinal displacement of the one rail to the other rail with corresponding entrainment of the sleepers should be feared, their freedom of movement is excluded by the positive engagement of the molded bodies with the sleeper heads.
  • these moldings can likewise be provided on the rail side with a bead which preferably extends beyond the web height of the rail. With the aid of these beads, sound radiation from the rail web and also partially from the wheel / rail top contact surface can then be reflected or absorbed.
  • the molded body On the side facing away from the rail, the molded body can be designed to fall off according to the position of the perineum.
  • the shaped bodies lying between the sleeper heads have an offset of the rail bearing width in the same way as the intermediate bodies Distance to the rail, in order to be able to carry out mechanical assembly or disassembly work on the rail fastening.
  • the shaped bodies have an angled contour at their butt joint to the adjacent shaped body, so that a triangular gap forms from the rail towards the outside.
  • This arrangement has two advantages, on the one hand, such a molded part can be easily stripped and, on the other hand, these molded parts can also be used for different curve radii on the inside of the track curve without the body shape having to be adapted.
  • An adaptation of the intermediate body to the radius is not necessary separately, since the joint width can vary within certain limits; Gap widths from 5 mm to 100 mm can easily be bridged through the polyurethane foam.
  • Both the intermediate body and the molded body can be provided with drainage channels on their contact surfaces for the removal of rainwater from the track.
  • rainwater can reach the surface of the solid base layer on both sides of the rail and can be removed from the central area of the one-piece intermediate body, for example by not completely filling the joint between the sleeper and the intermediate body or by foaming a drainage element there.
  • a two-piece or multi-piece intermediate body with a joint for example in the middle of the track, can of course also be placed in the sleeper compartments. This joint can then be used to drain surface water.
  • the bead can also extend laterally from the intermediate body over parts of the sleeper surface.
  • the molded body can be selected, so that there are more or fewer intermediate joints of the strand of molded body lined up as an endless bead on the outside of the rails.
  • the moldings can cover two sleeper compartments or just one Threshold compartment and preferably form their butt joint in the area of the center of the threshold.
  • the molded body can be made of aggregate-like concrete or similar material that is favorable in terms of sound technology. At least in part, for example in the bead area, material in the manner of a cement-bonded fiberboard can also be used.
  • a track grate of sleepers 2 and rails 3 with sleeper compartments 6 is fully adjusted on a solid base layer 1.
  • intermediate bodies 4 have been inserted between the sleepers 2, at a distance 43 from the rails.
  • joints 44-47 remain, with a joint 44, 46 on each side of the intermediate body through a drainage channel 48, which extends from the surface of the intermediate body to Base layer 1 is divided.
  • the other joint side 45, 47 is interrupted by a drainage channel 49.
  • molded bodies 5 are also placed in the outside sleeper compartments 62 between the sleeper heads 21, which bridge two sleeper compartments 62 and each form a joint 55 in the middle of a sleeper head 21.
  • the distance 54 of the moldings from the rail also enables a machine here Editing the rail fastener.
  • the shaped body 5 with its lateral oblique edges 53 forms the joints 58, 59 around the sleeper heads 21 laterally towards the sleeper compartments and above the sleeper heads 21 a joint 57 which extends to the sleeper head.At least the joints 58 and 59 accessible from the rail side are then foamed. If necessary, the joint 57 can also be foamed from the top of the threshold.
  • Figure 2 shows an asphalt base course generally designated 1 and its structure.
  • a hydraulically bound base layer 14 is applied to an earth planning 16 with the interposition of a drainage mat 15, on which a first concrete slab 13 was made in suburban concrete.
  • the track grating formed from the sleepers 2 and rails 3 then lies on an asphalt base layer 11 above the concrete slab 13.
  • Intermediate body 4 with its central part 41 and its rail-side bead 42 are each placed between two adjacent sleepers 2 (FIG. 1).
  • the middle part 41 of the intermediate body 4 has a height which is below that of the middle part 22 of the threshold 2.
  • the intermediate body 4 leaves the area of the rail fastening 33 free and its rail-side bead 42 lies a few millimeters below the rail upper edge 31 and the somewhat higher clearance profile L, shown here in broken lines.
  • the molded body 5 also leaves the rail fastening 33 free, but is designed so high that it just fills the clearance profile L and thus absorbs or reflects a sound emission from the web 32 of the rail 3 or through the wheel / rail contact on the rail top edge 31.
  • the bead on both sides of the rail can also be equipped with an open reverberation space which complements the reverberation space formed by the molded bodies and intermediate bodies under the rail. This also minimizes UV radiation on the asphalt surface at this point by shading.
  • the Shaped body 5 does not rest on the sleeper end 21, but is supported directly on the asphalt base layer or an equivalent layer 1.
  • the shaped body 5 On the slope side, ie on the side facing away from the rail, the shaped body 5 is adapted with its shoulder 52 to the slope contour 12. Precipitation is thus diverted to the substructure, which also has slope G.
  • the joints between the sleepers and the intermediate body or the molded body, which cannot be seen here, are all filled with polyurethane.
  • the molded body In order to prevent tipping or slipping, the molded body can also be fastened to the threshold with a suitable connector, if necessary.
