Definitions

  • the present invention relates to a rail track, in particular solid track, and a method for producing a rail track according to the preamble of claim 1.
  • the sleepers of railways serve to determine the lateral and vertical position of the rails. In addition, they transfer the forces acting on the rails to the ground.
  • the sleepers are embedded in a ballast bed.
  • sleepers are also used in so-called fixed carriageways, in which the sleepers are laid in particular on an asphalt or concrete layer or poured into a concrete layer.
  • the invention has for its object to provide an improved rail track and a method for their preparation.
  • the threshold can be secured against lateral displacement. It is particularly advantageous that the anchoring pin is displaceably guided in the receptacle. The occurring when loading the track vertical movements of the threshold are not hindered.
  • the receptacle is formed as a passage opening. An impact of the bolt with strong vertical movements of the threshold is thereby avoided.
  • the receptacle is formed by a sleeve cast into the threshold body, in particular a metal or plastic tube. This can be obtained with a simple production an accurate fit recording that allows vertical movements of the threshold and prevents damage in this area of the threshold.
  • the threshold body in its two longitudinal ends each have a lowered portion whose height is smaller than the height of the central portion under the rail fasteners.
  • the lowered portions in the longitudinal ends have on the one hand the advantage of a material saving and cost reduction.
  • the receptacles for anchoring bolts can be realized particularly advantageous by the lowered portions.
  • a rail track according to the invention is inserted according to an embodiment of the invention with a ballast bedding and into the ballast bed, formed the rails carrying sleepers, wherein the thresholds in one of the previously described types is executed. This results in the advantages described above in this rail carriageway.
  • the above-described sleepers are arranged on a concrete support layer. Again, the advantages described above arise.
  • the sleepers are underpoured with a leveling compound, in particular cast concrete or poured asphalt. As a result, a sufficiently flat bearing surface for the thresholds is created.
  • the sleepers rest on an asphalt base course and are formed according to one of the types described above. It again results in the advantages described above.
  • the asphalt base course is preferably applied to a hydraulically bound or unbonded base course.
  • the asphalt base layer can also be applied directly to the substrate, in particular to an antifreeze layer or a protective layer.
  • the individual layers may have a lower height due to the threshold according to the invention.
  • the production costs for the substructure are thereby reduced.
  • the threshold according to the invention may have a shorter length due to their properties. As a result, the necessary width of the substructure is reduced accordingly, which leads to a further cost reduction.
  • sound absorbers are preferably placed on the sleepers, both between the rails and also outside thereof.
  • the sound absorbers are preferably on their underside with a damping and friction increasing material such as foam rubber or the like. Mistake. The occurring during loading of the track movements of the sound absorber can not lead to destruction of the sound absorber or their bearing surfaces, and the sound absorbers are secured against slipping.
  • the railways on both sides of a ballast cover extends the sound insulation and protects the substructure of the sleepers.
  • the ballast can be easily plowed and picked up, so that the track for the necessary work can be easily exposed. Also can be carried out without substantial effort control of the track specification.
  • sleepers are used, which in each case have a receptacle in their end areas seen in relation to the longitudinal direction in which a bolt is slidably guided in its longitudinal direction, a recess is further introduced into the uppermost support layer in the region of the receptacle, filled into the recess a sealing compound, inserted into the receptacles each have a bolt and the threshold fixed until the potting compound is cured sufficiently to prevent over the bolt lateral displacement of the threshold.
  • the bolts may be formed relatively small in cross-section, since two bolts are provided for anchoring the threshold.
  • the recesses in the uppermost support layer can be made relatively small, so that they can be introduced by simple means in the support layer, for example by milling.
  • the receptacles are formed as a passage opening, so that the potting compound can be introduced, if desired, through the passage opening in the recesses of the support layer.
  • this embodiment has the advantage that the bolt can not abut on vertical movement of the threshold.
  • the bolts are installed in every second to sixth threshold, in straight sections in every fourth to sixth threshold and in bent sections in every second to fourth threshold.
  • the in the Fig. 1 to 3 shown threshold has a threshold body 1 with a seen in the direction of travel middle section 2 and two arranged on both sides of the central portion 2 sections 3.
  • the middle section 2 has a height h 1
  • the two lateral Portions 3 each have a height h 2 which is smaller by about a quarter than the height of 1 h.
  • the over the side portions 3 protruding part of the central portion 2 has the shape of a trapezoid with two oblique side walls 4, which enclose between them an angle ⁇ of about 45 °.
  • the adjoining the oblique side surfaces 4 upper sides 5 of the two lateral portions 3 are formed sloping sloping towards the two outer sides of the threshold body 1.
  • a fleece 10 is also arranged, which compensates for unevenness of the underside 11 of the threshold body 1 or the substructure 12.
  • a recess 13 which is located in the longitudinal center of the threshold body 1.
  • the recess 13 may be filled with an elastic filling material.
  • the sleeper body 1 also has on its one longitudinal side 14 an extension 15 and on its other longitudinal side 16 a reciprocally thereto recess 17.
  • the extensions 15 and the recesses 17 have seen from above trapezoidal shape. When installed, the extensions 15 each engage in the recess 17 of the adjacent threshold body 1.
  • the width b of the sleeper body 1 in the longitudinal direction I of the roadway is slightly smaller than the distance d successive threshold fasteners 8.
  • a gap 18 is formed between successive threshold bodies 1, which can be filled by an elastic material which as a profile on the long sides 14th , 16 of the threshold body 1 may be applied.
  • the two longitudinal end portions 19 of the threshold body 1 are each formed lowered and have a receptacle 20 for a bolt, which may be guided in the receptacles 20 in particular slidably.
  • the height h 3 of the portions 19 coincides with the height h 2 of the lateral portions. 3
  • the threshold Due to the reduced height h 2 of the two lateral sections 3, material for the sleeper body 1 and thus costs are saved. The same applies to the sections 19, the height h 3 is also smaller than the height h 1 of the central portion 2.
  • the threshold with a relatively large width b, in particular approximately the distance of successive rail fasteners 8 corresponding width without excessively increasing costs compared to conventional thresholds.
  • the broadening of the threshold has the advantage that the threshold is less easily rotatable about its longitudinal axis. A rotation of the threshold about a vertical axis is also made more difficult by the teeth due to the projections 15 engaging in the recesses 17. In addition, the extensions 15 also counteract a rotation of the threshold about its longitudinal axis.
  • Fig. 4 shows the anchoring of a threshold.
  • a bolt 22 is used for this purpose, which is guided in the receptacle 20 slidably.
  • the receptacle 20 is formed by a poured into the sleeper body 1 metal or plastic tube 23.
  • the bolt 22 is preferably made of metal.
  • the receptacle 20 is formed as a passage opening and closed on the top with a plug 24. The bolt 22 can thereby move unhindered in the receptacle 20.
  • the recess 25 is filled with a potting compound 26, which is liquid when the bolt 22 is introduced. Until the curing of the potting compound 26 of the sleeper body 1 with the bolt 22 and thus the track is determined by known means. After sufficient curing of the threshold body 1 is secured by the bolt 22 against lateral displacement.
  • the bolt 22 may be formed relatively small in cross section, since each threshold two such bolts 22 are provided.
  • the recess 25 may be formed in the base 12. It can therefore be introduced by simple measures such as milling in the substructure 12.
  • An embodiment of the fixing device as a spindle device for the spindling of the track to the required strength of the lower casting makes it possible to adjust the height of the sill and thus of the track, and to insert a lower casting.
  • Fig. 5 shows the construction of a railroad track with a threshold according to the invention.
  • a hydraulically bound support layer 27 On a hydraulically bound support layer 27, an asphalt or concrete bearing layer 28 is applied.
  • the stepped sleeper body 1 On the asphalt or concrete base layer 28 are the stepped sleeper body 1, which in turn carry the rails 9.
  • the structure is mirror-symmetrical to the plane II.
  • the soundproofing bodies 29 are supported on the lowered sections 3 and 19 of the threshold body 1. They have on their underside a foam rubber 30 or a similar material to dampen movement of the soundproofing body 29 and to prevent displacement.
  • the two sides of the railroad track are provided with a ballast cover 31 which, like the hydraulically bound support layer 27, builds up on the ground, in particular a layer protection layer or an antifreeze layer 32.
  • thresholds 1 are introduced into a ballast bed 33, which in turn builds on a layer protection layer or an antifreeze layer 32.
  • a concrete support layer 28 is applied to the substrate 32, a concrete support layer 28 directly. Between concrete support layer 28 and the thresholds 1 is an asphalt layer or a bituminous Potting compound 34 is provided in order to provide the most level possible support surface for the thresholds 1.
  • the asphalt base layer 28 is here applied to a hydraulically bound or an unbonded support layer 27, which in turn is supported on the substrate, in particular a layer protection layer or an antifreeze layer 32. Between Asphalttrag für 28 and the thresholds 1 may be provided a bituminous potting compound.
  • an asphalt base layer 28 is applied directly to the substrate 32, wherein the asphalt base layer 28 is preferably constructed of several layers and ends up with an asphalt fine concrete layer. Or it is provided between asphalt base course 28 and the thresholds 1 again a bituminous potting compound.
  • the threshold according to the invention can be used with advantage. It covers the substructure 12 largely completely, thereby preventing damage from sunlight. Likewise, water is drained and kept away from the base 12.
  • the substructure 12 may also be simpler in construction due to the characteristics of the threshold according to the invention.
  • the individual parts of the substructure 12, such as asphalt base layer 28 or concrete base layer 28, as well as hydraulically bound or unbound base layer 27 may have a smaller height.
  • the threshold may be a reduced length compared to normal thresholds have, for example, 2.60 m, so that the substructure 12 may be formed correspondingly narrower. This is due to the good power distribution due to the inventive design of the threshold body 1.
  • the introduced via the rails 9 forces are namely distributed by the thresholds 1 according to the invention to a larger area.
