Definitions

  • the invention concerns a railway comprising successive sleepers, whereby these sleepers have a cross beam to mutually connect two rails of the railway situated next to one another and at a certain distance, whereby at least an arm is provided near the far ends of the cross beam, at right angles to the cross beam, which arm is forming a longitudinal continuous support of a rail extending in the longitudinal direction of said arm.
  • the document JP-A-09273102 discloses a "ladder type sleeper" that is used to increase the surface between the gravel bed and the sleepers in order to disperse the load of a train over a larger surface of the gravel bed. Ballastless railway tracks with partially embedded sleepers are generally known in the art.
  • the invention mainly aims a railway which makes it possible, to a very large extent, to reduce the noise nuisance arising from coaches and the like, such as trains or trams, riding on railways.
  • said arms near the corresponding far ends of the cross beams, are situated in line and extend with their free ends substantially against each other, so as to form a substantially continuous support for a rail, resting on said arms in the longitudinal direction, whereby the sleepers are at least partially embedded in a concrete base layer.
  • the sleepers are preferably made of concrete.
  • two side arms are provided near the two far ends of the cross beam, situated opposite to one another, in line, and extending on either side of the cross beam, which are parallel to the base of said cross beam.
  • the above-mentioned arms near a specific free end of the cross beam are shorter than the arms which are provided near the other far end of the cross beam.
  • coupling means are provided on the free ends of the side arms, which make it possible to connect two arms of two successive cross beams of a railway, situated opposite to one another and in line.
  • Said railway is thus characterised in that its rails rest, in a continuous manner and over their entire length, on the side arms of the cross beams, whereby these arms extend under the rails in the longitudinal direction of the latter, in such a manner that the free ends of the arms of two successive sleepers, directed towards one another, substantially connect and, preferably, are coupled to one another by means of coupling means possibly known as such.
  • the invention in the first place concerns a sleeper 1 made of concrete which consists of a cross beam 2 to mutually connect rails situated next to one another and at a certain distance.
  • Said sleeper 1 has at least one and, as represented in figures 1 to 3, preferably four side arms 3, 4, 5 and 6 which extend at right angles to the cross beam 2 and which are designed as a longitudinal, preferably continuous support of the rails.
  • These rails which are known as such are schematically represented in figure 1 by an axis 7.
  • Said arms 3, 4, 5 and 6 are provided in pairs near each of the two far ends of the cross beam 2, and they extend on either side, crosswise to the latter.
  • the arm 3 extends in line with the arm 4, near one of the far ends of the cross beam 2, and it has the same length as the arm 4, whereas the arms 5 and 6, which extend in line near the other far end of the cross beams 2 and 4, also have the same length.
  • the arms 3 and 4 are somewhat longer, for example 1 to 6%, than the arms 5 and 6.
  • the far ends of the arms 3, 4, 5 and 6 are bevelled to this end, and thus each have an end face.
  • the end faces of the arms 3 and 5, 4 and 6 respectively, which are provided on one and the same side of the cross beam 2, are situated in a single plane which extends almost crosswise to the top face of the sleeper and which forms an angle with the longitudinal axis of the cross beam 2 which is not 90°.
  • the angle between these end faces and the longitudinal axis of the sleeper 2 is between 1° and 5°, preferably almost 1.5°.
  • a specific radius of curvature for an arched part of the railway is obtained by placing a specific number of sleepers with their shortest and longest arms in line next to one another, possibly alternating with a sleeper which is turned over 180° around a vertical axis.
  • coupling means On the free ends of the arms are preferably provided coupling means which make it possible to mutually connect two arms situated opposite to one another and in line.
  • Such coupling means make sure that transverse forces arising in a certain sleeper are divided over the adjacent sleepers. Such transverse forces arise for example when a train rides over the railway. As the transverse forces are divided over different sleepers, the rails 7 will bend only slightly or not at all under the load of a train.
  • the coupling element is made such that it is possible to build bent railways with varying radiuses of curvature with one and the same type of sleeper.
  • Figure 6 represents a first embodiment of such a coupling element which consists of a sleeve 8 which is slid on two free ends of arms 3, 4, 5 and 6 situated in line and directed towards one another, whereby also the free ends are directed towards one another.
  • Figures 7 and 8 represent another embodiment of a coupling means.
  • This coupling means consists of a mortise and tenon joint, whereby the free ends of the arms which are situated on one side of the cross beam 2 are provided with a pen or dowel 9, and the free ends of the arms on the other side of the cross beam are provided with a corresponding opening 10, which consists for example of a recess. Also in this embodiment, one has to make sure that the two arms connected to one another can slightly rotate.
  • the coupling means is formed of protrusions 20 which are provided near the far end of the above-mentioned arms 3, 4, 5 and 6 and which extend almost crosswise to the latter.
  • the protrusions 20 are situated on the standing lateral surfaces of the arms 3, 4, 5 and 6.
  • protrusions 20 consist of metal rods which extend through the arms 3, 4, 5 and 6 and which are thus anchored in the sleeper 1. In an advantageous manner, these protrusions 20 are part of a reinforcement provided in the sleepers 1, which is not represented in the figures.
  • the sleeper according to the invention can be provided with at least one adjusting means 13.
  • Such an adjusting means 13 makes it possible to set the height of cross beams 2 connecting to one another in a railway, such that the rails can be laid substantially entirely flat.
  • the adjusting means 13 comprises a bolt 21 which can be moved according to the longitudinal direction thereof and which extends substantially vertically to underneath the lower surface 22 of the corresponding sleeper 1.
  • Said bolt 21 works in conjunction with a vertical recess 26 provided to this end, provided near one far end 23 of the cross beam 2.
  • This recess extends from the upper surface 24 of the sleeper 1 up to the lower surface 22 thereof, such that, in order to adjust the height of a sleeper 1, all one has to do is turn the bolt 21 extending in the recess via the upper surface 24, such that it is moved in a vertical direction in relation to the sleeper 1.
  • the cross beam 2 and the arms 3, 4, 5 and 6 represent a cross section in the shape of a trapezium, whose largest side may be situated both at the top or at the bottom.
  • a longitudinal, collar-shaped edge 11 will preferably be provided on the lower side of the cross beam 2 and of the arms 3, 4, 5 and 6, for example as is represented in the accompanying figure 11.
  • Sleepers 1 are placed next to one another, whereby, as described above, the far ends of the arms 3, 4, 5 and 6 of successive sleepers 1 connect to one another.
  • the sleepers 1 hereby lean via the above-mentioned adjusting means, in particular via the lower end of the bolt 21, on an adjusting tile 14 which rests on the bottom 12 upon which the railway is built.
  • Said adjusting tile 14 preferably consists of a concrete slab and makes sure that the load, resulting from the weight of the sleeper 1, is sufficiently divided to prevent the bolt 21 from penetrating in the bottom 12.
  • the protrusions 20 of two connecting arms 3, 4, 5 and 6 are connected to one another by means of at least one relatively rigid connecting element 25.
  • This connecting element 25 preferably consists of one or several metal rods which are welded onto the protrusion 20, situated on one and the same side of the respective arms 3, 4, 5 and 6. Thus is formed a relatively rigid connection between two connecting arms of two sleepers lying next to one another.
  • the sleepers 1 which are part of the railway, have been connected to one another via the respective coupling means, and after the height of the different sleepers has been adjusted with the above-mentioned adjusting means 13, the sleepers 1 are cast in concrete, at the most up to the height of their upper surface 24, as indicated by means of reference figure 15 in figure 12. Consequently, the space between and under the sleepers 1 is thus filled with concrete, whereby the coupling means are also surrounded by concrete.
  • the next step consists in fixing the rails 16 according to the axis 7 of the arms 3, 4, 5 and 6 on the cross beams 2 by means of fastening means known as such and which are not represented in the accompanying drawings, such as "Vossloh” fasteners, which consist of a spring terminal which is pressed onto the side edge of the foot of the rail by means of a bolt.
  • the rails 16 hereby rest over their entire length on the aforesaid arms 3, 4, 5 and 6 of the sleepers 1 lying next to one another.
  • an elastic strip can be provided between the rails 16 and the arms 3, 4, 5 and 6, which is not represented in the accompanying drawings.
  • the cross beam 2 consists of two concrete blocks 17 and 18 which are mutually connected to one another by means of a metal strut 19 whose far ends are anchored in these blocks 17 and 18 and whose axis is situated in the plane of symmetry of the latter.
  • This strut 19 has for example an L- or I-shaped cross section.
  • the cross beam extends over the entire length of the arms, such that the short arms of the sleeper are transferred in a continuous manner in the long arms thereof, via said cross beam.
  • the sleeper according to the invention may consist of a cross beam with only two arms extending on either side on one of the far ends 23 of the cross beam. Possibly, the free ends of the arms 3, 4, 5 and 6 may be slightly bevelled, such that two arms situated in line can be better connected to one another.
