Definitions

  • the invention relates to a rail with a continuous support in the rail trough of a steel construction or by concrete slabs and the like, attached therein by means of a two-component embedding material.
  • high grooved rails are used in a customary manner with a high section modulus in the load direction and with a rail base width of up to 18 cm and larger and are positioned on a compacted subgrade, whereby an exact spacing takes place by means of metallic spacing means to construct a track.
  • An extensive planeness of rail head or of running head and guiding head of the grooved rail and the road surface or design surface is achieved by means of filler material, optionally with a pavement.
  • a track with rails sunk into a surface can also be constructed in that one or more concrete slab(s) in succession are used as a supporting structure with two U-shaped recesses in the longitudinal direction, a so-called rail trough to hold Vignol rails.
  • a potentially elastic two-component material such as, e.g. polyurethane foam or the like.
  • a rail mounting of this type to form a track is possible in an advantageous manner both in concrete slabs and in steel constructions, whereby a continuous support of the rails is made possible, so that even Vignol rails with a lower moment of inertia can be used.
  • a mounting of Vignol rails according to the above method in a rail trough has the disadvantage that high volumes of encasement material are necessary to embed or fix the rails in the rail trough. Furthermore, it is expedient with respect to the wheel flange of the wheels to lower the level of the rail embedding on the interior side of the track, which can mean an additional expenditure. Finally, the head width of a Vignol rail is small with respect to the base width, which increases the lateral surfaces of the potentially soft embedding material in the road surface area and augments the danger of wear, and also renders necessary high encasement volumes for embedding the rails.
  • the object of the invention is to create a rail of the type mentioned at the outset which avoids the disadvantages stated, can be connected by means of fishplates, is very cost-effective in terms of a production with a head hardening, requires a low volume of embedding material for the fixation in a rail trough and achieves a high stability and durability of the track.
  • the rail is embodied as a grooved rail with a running head, a guiding head, a web and a rail base, has a greatest height with respect to the support area of the rail base of more than 10.0 cm, but less than 12.4 cm, a total width of the base of more than 10.1 cm, but less than 14.0 cm, a width of the running head of essentially 5.1 cm to 6.3 cm, and two fishplate recesses arranged on both sides of the rail web, whereby the fishplate recess facing the guiding head with respect to the cross section of the rail has a width of the planar basis of at least 1.64 cm.
  • a use of a grooved rail minimizes in a favorable manner the exterior surface of the embedding material towards the road surface, whereby also its cross-sectional profile is directed towards a high stability and load capacity during the operation of the track and towards a negotiability for essentially all conventional rail wheels.
  • the fishplate recesses are advantageously dimensioned such that the bores for mounting the connecting pieces sufficiently ensure their mechanical load capacity.
  • the minimum total width of the rail base is dimensioned, whereby the largest width of the same according to the invention is determined with respect to minimizing the rail trough cross section.
  • the height of the grooved rail according to the invention is defined with a dimension that renders possible a small rail trough depth with high load capacity and thus an advantageous and economic embodiment of the foundation component(s).
  • a particularly advantageous embodiment of the grooved rail according to the invention can be achieved if, perpendicular to the support area of the rail base, the guiding head and the rail base flange on the same side have an essentially equal projection with respect to the web of the rail, and that on the opposite side the projection of the rail base flange extends beyond the projection of the running head, preferably extends beyond it by more than 1.0 cm.
  • This cross-sectional design can on the one hand reduce the support function of the rail base during a loading of the running head in curves and thus reduce the highest surface pressure at the flange end of the same and achieve approximately a favorable rectangular shape of the perimeter of the rail cross section.
  • the rail cross-sectional area is less than 75.0 cm 2 , but more than 69.0 cm 2 , and if the moment of inertia with respect to axis xx exceeds an amount of 800.0 cm 4 and the moment of inertia with respect to axis yy is lower than 650 cm 4 .
  • the elastic deformation of the rail can be adjusted favorably to the installation components.
  • a particularly favorable setting of the maximum tensions during a bending by the wheel load can be achieved if the center of gravity of the rail cross-sectional area at a height of the axis xx is in the range of 0.456 to 0.54 times the rail height.
  • the rail cross-sectional area is advantageously embodied such that the connecting line from the interior part of the running head to the outmost projection part of the projecting rail base flange has an angle in the range of 30° to 35°.
  • the running head has a greater hardness and/or wear resistance than the web part of the rail, i.e., that at least the running head, advantageously the running head and the guiding head of the grooved rail, are hardened, the service life of the track can be considerably extended even in heavily loaded operation.
  • the cross section of the grooved rail is designed such that the rail ends can be connected to further rails or switch parts by means of fishplates with through bolts.
  • the rails can thus be reliably linked, even if a front-face welding of the ends should not take place.
  • FIG. 1 A grooved rail
  • FIG. 2 A grooved rail in a rail trough
  • FIG. 1 shows the cross section of a grooved rail according to the invention.
  • a rail head with a total width B has a running head 1 and a guiding head 2 with a groove lying between them.
  • a web 3 connects the rail head to a rail base 4 , whereby a projection of the guiding head 2 and of a base flange 42 with respect to a vertical axis yy have an essentially equal dimension.
  • a projection of the running head 1 with respect to the vertical axis yy is smaller than that of a base flange 42 .
  • a greatest height A of the grooved rail is embodied such that—in cross section—a connecting line from an interior delimitation of the running head 1 to the outmost part of a support area 40 of the flange 41 of the rail base 4 has an angle ⁇ of more than 30°, but less than 35°.
  • the height H of the center of gravity S of the cross-sectional area of the grooved rail is (0.456 to 0.54) times the greatest height H.
  • a fishplate recess facing the guiding head has a planar basis with a width D of at least 1.64 cm, so that it is possible to ensure sufficient stability and strength of a bored fishplate.
  • FIG. 2 shows a rail according to the invention installed in a rail trough.
  • a grooved rail according to the invention with a running head 1 and a guiding head 2 is embedded in a structural part 5 formed with a steel construction or a concrete slab such that only the running head 1 slightly extends in a vertical manner beyond the surface of the structural part, e.g., a concrete road surface and an embedding material 6 .
  • holes 21 are indicated in dashed lines, which holes are connected to a water discharge means 7 and are thus able to keep the groove clear of accumulated rain water or melt water.
  • an overlay 61 can be positioned in varying strength and with selected damping properties.
