Definitions

  • the invention concerns a vibration isolator with an elastic boot for continuously supported rails which are embedded in a railway bed, whereby the rails have a rail head and a rail foot which are connected by means of a rail body with two sides having each a lateral cavity extending over the entire length of the rail between the rail head and the rail foot.
  • the elastic boot fits closely to the rail and extends over practically the full length of the rail. It envelops the rail almost entirely, leaving the top side of the rail head accessible, such that a railway vehicle can move over it.
  • the elastic boot may consist of preferably at least three parts, namely a first and a second part which mainly extend in the lateral cavities on either side of the rail body and a third part which mainly extends under the rail foot. Further, this third part also fits closely to the first and second part of the boot.
  • the elastic boot makes sure that the rail is kept in place in a groove in the railway bed, which is preferably made of concrete.
  • the rail is clamped in this groove by the elastic boot and, preferably, no additional fastening means are thereby required for fixing the rails to the railway bed.
  • such elastic boots are clamped against the rail, after which the latter is embedded in a concrete railway bed.
  • these boots are glued to one another and/or to the rails by means of adhesive.
  • the elastic boot may also be formed by casting the elastic material in a mould round the rail.
  • Patents DE4004208 , DE4344815 and EP0854234 describe a boot which is mainly formed of three elastic parts which are fixed to the rail by means of additional fastening means.
  • European patent EP1807569 also describes such a boot which is formed of three parts being clamped to the rail by means of additional external clamping means, after which this rail is embedded in concrete together with the boot. Further, this patent describes a method for installing and embedding a rail in a railway bed at a railway site.
  • the rails which are enveloped by an elastic boot are hereby put in a correct position in relation to one another by means of installation bridges over the railway to be installed.
  • the rails with the elastic boot are clamped under the rail head by means of claws via the flanks of the boot and hung under the installation bridges. It is also possible for these enveloped rails to be supported via the rail foot.
  • the railway bed is subsequently provided round the enveloped rails.
  • the claws will have to be removed so as to be able to also provide material from the railway bed against the flanks of the boot where said claws are situated.
  • the invention aims to remedy these disadvantages by proposing a vibration isolator and a method making it possible to provide a vibration-isolating boot in a simple manner on the rails and to subsequently embed them in concrete without any adhesives being required or without any separate clamping means having to be provided and/or removed.
  • the rail preferably must not be entirely revolved around its longitudinal axis when covering the rail.
  • the boot can hereby be also simply provided on the site where the railway is being installed.
  • the proposed vibration isolator makes it possible to restrict electric leakage currents.
  • the elastic boot of the vibration isolator according to the invention is designed such that the third part of the boot is fixed by means of a tongue and groove joint, and such that the first part is clamped between the rail and this third part so as to fix the elastic boot to the rail, as claimed in the annexed claims.
  • the third part is provided with a standing wall extending past the rail foot and which connects to a flank of the first part, such that said tongue and groove joint connects the standing wall to the first part and/or to the far end of the rail foot.
  • the tongue and groove joint consists of at least one rib and a corresponding recess in which this rib fits, whereby they extend over practically the full length of the elastic boot.
  • This rib and the corresponding recess co-operate in order to fix the third part to the first part.
  • the tongue and groove joint is preferably elastically deformable, for example as said rib and recess are elastically deformable.
  • the third part rests on the top side of the rail foot and the third part preferably also partly clamps the first part between this third part and the top side of the rail foot.
  • the tongue and groove joint extends between the first part and the third part, preferably between the rail head and the rail foot, when the elastic boot envelops the rail.
  • the invention also concerns a method for making a railway bed with an embedded continuously supported rail with a rail head and a rail foot which are mutually connected by a rail body.
  • the rails are suspended in a correct position via the rail head, such that, preferably, the rail body and the rail foot are freely accessible.
  • a first part and a second part of the elastic boot are put in a first lateral cavity and a second lateral cavity of the rail respectively, on a first side and a second side respectively of the rail, such that the first and second part extend over practically the full length of the rail.
  • a third part of the elastic boot is put over the bottom side of the rail foot, such that this third part at least partly clamps the first part between the rail and this third part, as a result of which the boot is fixed to the rail.
  • the bottom side of the rail is freely accessible.
  • the rails can be suspended to the rail head via the top side of this rail head by means of a magnet, such that the rail body, the rail foot, the bottom side and the lateral sides of the rail head are freely accessible.
  • the invention generally concerns a vibration isolator comprising an elastic boot for a rail embedded in a railway bed, whereby the top side of the rail head practically corresponds to the top side of the railway bed and whereby the rails are continuously supported by the elastic boot.
  • the invention concerns an elastic boot for rails having a rail head and a rail foot which are mutually connected by means of a rail body having two sides with a lateral cavity on each side extending over the full length of the rail between the rail head and the rail foot.
  • the elastic boot has been designed such that it envelops the rail practically entirely, thereby leaving the rail head accessible for a railway vehicle to move over the latter.
  • the rail is entirely insulated in relation to the railway bed by the boot.
  • the elastic material of this boot is sufficiently rigid to continuously support the rail and to make sure that the rail is kept in place in a groove in the railway bed when a railway vehicle moves over this rail.
  • Such elastic materials are already known to the expert and they may consist for example of rubber or recycled rubber as described in European patents EP0854234 and EP 1807569 .
  • a possible practical first embodiment of the vibration isolator according to the invention is schematically represented in figures 1 and 2 .
  • This vibration isolator comprises an elastic boot which fits closely to the rail and extends over almost the full length of the rail.
  • the boot may be built of several units extending in one another's prolongation according to the longitudinal direction of the rail. These units preferably have a length of 1 to 2 metres. Further, the boot practically entirely envelops the rail, thereby leaving the top side of the rail head 4 accessible, such that a railway vehicle can move over the latter.
  • the boot is formed of at least three parts 1, 2 and 3 extending in the longitudinal direction of the rail.
  • a first part 1 extends in a first cavity 7 of a first lateral side of the rail whereas a second part 2 extends in a second cavity 7 of a second side of the rail.
  • first and second parts 1 and 2 rest on the top side 10 of the rail foot 5 and are preferably at least partly clamped between the top side 10 of the rail foot 5 and the bottom side 11 of the rail head 4. Consequently, these first and second parts 1 and 2 at least partly fit closely onto the rail and at least partly fill the lateral cavities 7 between the rail foot 5 and the rail head 4.
  • These first and second parts 1 and 2 each have a flank 19 which is turned away from the rail and practically parallel to the rail body 6.
  • a third part 3 of the elastic boot extends under the rail foot 5.
  • This third part 3 has a U-shaped cross section and is sufficiently rigid for the rail to rest on. If this third part 3 is put over the bottom side 12 of the rail foot, this part 3 will extend past the top side 10 of the rail foot 5.
  • This third part 3 connects the first part 1 to the second part 2 and fits closely to the bottom side 12 of the rail foot 5, which rests on said third part 3.
  • the third part 3 hereby also fits closely to the flanks 19 of the first part 1 and the second part 2 of the boot.
  • these parts 1, 2 and 3 mutually fit in such a way that a watertight boot is obtained.
  • said third part 3 preferably has a U-shaped cross section with a basis 15 and two standing walls 16 extending opposite one another.
  • the basis 15 will thus fit onto said bottom side 12, and the walls 16 will fit onto said first part 1 and said second part 2 respectively.
  • the standing walls 16 at least partly overlap the flanks 19 of the first and second parts 1 and 2.
  • the rail is put in the U-shaped part 3 together with the first and second part 1 and 2 of the boot.
  • the boot is hereby provided with at least a tongue and groove joint with which the third part 3 is fixed to the first part 1, and with a tongue and groove joint with which the third part 3 is fixed to the second part 2.
  • the tongue and groove joint comprises a tongue with a rib 8 and a corresponding groove with a notch 9 in which the rib 8 fits.
  • the elastic boot is provided with at least one rib 8 and a corresponding notch 9 in which this rib 8 fits, such that the third part 3 is fixed to the standing flanks 19 of the first part 1 and the second part 2 respectively. This also makes it possible to obtain a watertight seal between said three parts 1, 2 and 3.
  • the first part 1 and the second part 2 are provided with ribs 8, and the third part 3 is provided with two corresponding notches 9 in which these ribs 8 fit.
  • These ribs 8 and notches 9 extend over the full length of the boot.
  • said notches 9 are provided in the sides of the standing walls 16 turned towards one another, whereas said ribs 8 are situated in a corresponding position on the flanks 19 at the second and third part 2 and 3.
  • the third part 3 hereby also clamps the first part 1 and the second part 2 between the third part 3 and the rail. Consequently, the elastic boot is also fixed to the rail as a result thereof.
  • This construction is advantageous in that it is not necessary to glue the different parts of the boot together or onto the rail.
  • Other fastening means such as clips or clamps are not required either to fix the boot to the rail.
  • the first and second parts 1 and 2 are preferably first provided in the lateral cavities 7 of the rail and the third part 3 is subsequently provided over the bottom side of the rail foot and the flanks of the first and second part.
  • the third part 3 can hereby be brought towards the rail with the first and second parts 1 and 2 or vice versa. According to the method of the invention, this can be done without having to revolve the rail round its longitudinal axis.
  • a second embodiment of the invention is represented in figure 3 and differs from the above-described first embodiment in that, in order to fix the third part 3 of the elastic boot to the first part 1 and the second part 2, also ribs 8' are provided to this third part 3, whereas corresponding recesses 9' are provided in the first part 1 and the second part 2 of the boot.
  • these ribs 8' protrude over the top side 10 of the rail foot 5 when the third part 3 has been put over the bottom side 12 of the rail foot 5.
  • the first and second parts 1 and 2 further also have ribs 8 which should fit on top of the far ends 18 of the rail foot 5.
  • the far ends 18 of the rail foot 5 are formed by the lateral sides of the rail foot 5.
  • the third part 3 is hereby provided with two corresponding notches 9 in which the ribs 8 fit together with the far ends 18 of the rail foot 5. As in the first embodiment, the ribs 8 and 8' and the notches 9 and 9' extend over the full length of the boot.
  • this embodiment comprises two different tongue and groove joints.
  • a first tongue and groove joint comprises a tongue with a rib 8' of the standing wall 16 and a corresponding groove with a notch 9' in the flank 19 of the first or the second part 1 or 2.
  • a second tongue and groove joint comprises a tongue with a rib 8 of the first or the second part 1 or 2, together with a far end 18 of the rail foot 5 and a corresponding groove with a notch 9 in the standing wall 16.
  • a third possible embodiment of the invention differs from the above-described first embodiment in that the second and the third part 2 and 3 of the boot are formed of a whole. Consequently, these two parts 2 and 3 are permanently connected to one another. A recess 13 extending over almost the full length of the boot can be provided between the second 2 and the third part 3. As a result, the connection 14 between these parts 2 and 3 is easily elastically deformable, such that they can rotate in relation to one another.
  • the standing wall 16 is moved past the rail foot 5, against the flank 19 of the first part 1.
  • a fourth and fifth possible embodiment of the invention mainly differ from the above-described second and third embodiment in that the third part 3 is provided over a rib 8 and the rail foot 5 and has been designed such that the rib 8 as well as a far end 18 of the rail foot 5 fit in the notch 9.
  • the rib 8 and the far end 18 of the rail foot 5 hereby fit closely together. Further, an edge 17 of the third part 3 thus extends over the top side 10 of the rail foot 5.
  • the tongue and groove joint comprises a tongue comprising the rib 8 as well as the far end 18 of the rail and a corresponding groove comprising the notch 9 in the standing wall 16 of the third part 3.
  • a sixth possible embodiment of the invention is shown in figure 7 and mainly differs from the second, fourth and fifth embodiment in that the notch 9 in the third part 3 has been designed such that only the far end 18 of the rail foot 5 fits in it.
  • These notches 9 in the third part 3, together with the far ends 18 of the rail foot 5, form tongue and groove joints with which the third part 3 is fixed to the rail foot 5, such that this third part 3 further clamps the first and second parts 1 and 2 between this third part 3 and the rail.
  • this far end 18 makes sure that the tongue is not elastically deformable, as in the sixth embodiment, or it makes sure that the rib 8 is less elastically deformable, as in the second, fourth and fifth embodiment.
  • this connection is much more solid and for example less dependable of a correct fit of the first and second parts 1 and 2.
  • the standing walls 16 of the third part 3 in these embodiments have at least an edge 17 and/or a rib 8' extending over the top side 10 of the rail foot 5, such that the far end 18 of the rail foot 5 is clamped as a result thereof.
  • the third part 3 is fixed to the far ends 18 of the rail foot 5.
  • the third part 3 possibly comprises an elastic bottom, not represented in the figures, which fits onto the bottom side 12 of the rail foot 5 and which is selected as a function of the expected load of the rail and the required vibration damping.
  • the elastic boot is formed such that its inside preferably fits almost entirely onto the rail.
  • the outside of the elastic boot further fits onto the groove in the railway bed. This elastic boot prevents the rail from making any direct contact with the railway bed.
  • the rail can also be provided with an electrically insulating layer 20 provided round the rail foot 5 between the rail and the elastic boot, as represented in figures 7 and 8 .
  • This insulating layer 20 extends over the full length of the rail from one side of the rail body 6, over the entire rail foot 5, up to the other side of the rail body 6.
  • the electrically insulating layer can be made of materials known as such, such as PP, i.e. polypropylene, rubber, PVC, i.e. polyvinylchloride, XLPE, i.e. cross-linked polyethene, which provide a better electric insulation than the elastic material out of which parts 1, 2 and 3 of the boot are made.
  • the thickness of this electrically insulating layer 20 is preferably smaller than the thickness of the elastic boot. In particular, this thickness is preferably smaller than the smallest thickness of the elastic boot. This thickness preferably amounts to 0.5 to 5 mm.
  • the electrically insulating layer 20 may consist of a foil or a coating which is provided on the rail and/or on the inside of the elastic boot. According to an advantageous embodiment of the invention, the electrically insulating layer 20 is formed of a foil of polypropylene having a thickness of 0.5 to 2 mm and which preferably amounts to practically 1 mm. This additional electrically insulating layer 20 does not need to extend up to the rail head 4 to provide a sufficient electric insulation for the rail, together with the elastic boot. This layer 20 only needs to cover the rail foot 5 and possibly a part of the rail body 6.
  • the additional electrically insulating layer 20 helps to prevent any stray current which may occur in the rails enveloped by an elastic boot in embedded rails of for example electrified tram rails.
  • this electrically insulating layer 20 can be applied in all the above-described embodiments of the invention, but also in other existing elastic boots for continuously supported and/or embedded rails.
  • this additional insulating layer 20 can also be applied to a rail whereby an elastic boot is cast round the rail.
  • the electrically insulating layer 20 can be glued on the rail and/or it can be clamped between the rail and the elastic boot.
  • the invention also concerns a method for installing and embedding a rail on a railway site and for making a railway bed with embedded continuously supported rails.
  • the method makes it possible to put the rails in a correct position and to then cast the hardening of the railway bed round the rails up to practically the same height as the top side 24 of the rail head 4.
  • uncovered rails are suspended via the rail head 4 over a foundation by means of an installation bridge 22 with claw means 21, such that the rail body 6 and the rail foot 5 are freely accessible, as is also represented in figures 9 and 10 .
  • the rail is hereby put in its required position on the site. It is hereby made sure that the top sides of connecting rails are situated in one and the same plane, or in other words, that successive connecting rails are aligned. Further, it is also made sure that the distance up to an adjacent rail and the height in relation to this adjacent rail is correct, such that together they form the tracks of a railway. Consequently, the rail is also aligned in relation to an adjacent rail.
  • first part 1 of the elastic boot is provided in a first lateral cavity 7 of the rail and, in an analogous manner, a second part 2 of the elastic boot is provided in a second lateral cavity 7 on the other side of the rail.
  • the first part 1 and the second part 2 hereby extend on either side of the rail over preferably almost the full length of this rail.
