Definitions

  • the invention relates to a positionally stable track body and the use of Precast concrete parts for this track body.
  • the threshold's lateral displacement resistance is characterized by a shear force base Increase asphalt, using either two-block sleepers, or the threshold in its middle area on the sole for positive locking the transverse force base receives a recess.
  • German patent specifications 39 01 347 and 43 28 668 have been proposed to close the concrete sleepers in a concrete tub place and then fill the compartments between the sleepers with concrete or to press the concrete sleepers into the fresh in-situ concrete.
  • the threshold can be temporarily fastened to the base layer by means of a polyurethane adhesive before the compartments are poured out, before the concrete is then leveled in the threshold surfaces. 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.
  • the intermediate bodies are then screwed onto the fixed support plate with the aid of a screw, and 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 plates 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 in position with the substructure made of reinforced concrete, for example by pouring 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 and from DE-Laid-Open Publications 44 17 402 and 44 37 826, sound absorber elements are known for solid carriageways which are made of aggregate concrete , cement-bonded expanded clay or resin-bonded foam glass, if necessary 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 15 935 . 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 a stable position Propose track grate, the production of which is as simple as possible, under Avoiding clasps with the fixed support plate under the Track panel.
  • the problem is solved by a track body Claim 1 solved.
  • Developments of the invention are in the Subclaims recorded.
  • 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.
  • the tolerances of the concrete sleepers and intermediate bodies, as well as their actual position on the solid subsoil more or less wide gaps are formed between the outer sides of the sleepers and the track direction. 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 e.g. Find polyurethane foam as used in construction technology, e.g. at the Inserting doors or windows in building construction is constantly used. With a joint thickness of 3 cm and a joint length of 15 dm one is sufficient commercial bottle from 3/4 I to about 50 intermediate bodies in the To fix threshold subjects. It is assumed that the intermediate body do not cover the area of the rail fastening, but this part leave the sleeper compartment free to use the usual construction machinery Check the rail mounting and, if necessary, dismantle it.
  • such an intermediate body is made made in one piece, being in the middle of the track according to the Threshold thickness is formed and increases towards the rail to the level of about 5 to 40 mm below the top edge of the rail.
  • the thickness should be in the middle of the track of the intermediate body even slightly below the corresponding one Threshold thickness are so that on the one hand an electrical conductor on the Thresholds can be placed and on the other hand easily one Rails are stored in the middle of the track for later assembly can without damaging or stressing the intermediate body and so in to introduce impermissible loads into the foamed joint.
  • the for The upper edge of the rail should not be formed on the rail side protrude so that an earth fault to the overhead cables Rail is possible.
  • the Intermediate body is preferably Einkornbeton, the large-pored and is permeable to water. However, others can - for themselves known materials are used for the invention Intermediate body.
  • Such a stiffened track grate especially when concrete sleepers and intermediate body made of concrete has a total weight, which leads to such a high coefficient of friction that a transverse displacement of the track grating seems impossible due to the frictional forces alone.
  • the coefficient of friction can by under the sole of the threshold and / or the intermediate body elastic, soft plastic parts to be arranged are increased.
  • the deformable plastic will also be a full support and a acoustic decoupling to the base layer achieved. Since the threshold and the intermediate body rests equally on the solid base layer and are elastically connected to each other by the foaming of the joint under operating load also no differential movement with regard to the Expected to sink. Possible torsions in the millimeter range can can be easily caught by the elastic foam.
  • the intermediate body can be transferred.
  • Systems can also add thresholds to the threshold heads and partly or completely bridging the threshold ends and the Shaped bodies covering the threshold ends made of the same material as the Intermediate body are arranged, in which this also between the Sleepers can be placed on the asphalt base course.
  • the Threshold-side joints or, if necessary, all joints on Threshold ends can also be made with the aforementioned foam be sprayed out. Even if torsional forces, i.e. on different longitudinal displacement of one rail to the other rail should be feared with appropriate entrainment of the thresholds whose freedom of movement through the positive locking of the molded body to the Threshold heads excluded.
  • these moldings can - as known for published Sound absorber elements, also provided with a bead on the track side be, which preferably extends up to the web height of the rail. With With the help of these beads, a sound radiation can then be emitted from the rail web and also partially reflects the wheel / rail top contact surface or be absorbed.
  • the Shaped body On the side facing away from the rail, the Shaped body be designed sloping according to the position of the perineum.
  • the shaped bodies lying between the sleeper heads have the same Like the intermediate bodies, one offset by the rail bearing width Distance to the rail in order to assemble or mechanically To be able to carry out disassembly work on the rail fastening.
  • the Shaped bodies have a on their butt joint to the adjacent shaped body angled contour, so that from the rail to the outside forms a triangular gap.
  • This arrangement has two advantages, firstly such a molded part can be easily stripped and on the other hand these moldings also for different curve radii, inside the Track arch, usable without having to adjust the body shape.
  • An adaptation of the intermediate body to the radius is not separate required because the joint width can vary within certain limits; Gap widths from 5 mm to 100 mm are due to the polyurethane foam easy to bridge.
  • 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 of this type 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 in the track axis.
  • 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 shaped bodies can cover two sleeper compartments or can also form their butt joint, and preferably only in the region of the center of the sleeper head.
  • 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.
