Definitions

  • the present invention relates to a railway rail support slab track, that is to say without ballast. Such channels are used in particular in tunnels.
  • a railway rail support is composed of a concrete block or blochet whose upper part is provided with means for fixing the rail.
  • the shape of the lower part of the concrete block is, in turn, designed to adapt to the shape of an elastomeric envelope also called slipper.
  • an elastomeric sole whose surface is substantially equal to the surface of the lower face of the block.
  • This sole has an elasticity adapted to the nature of the traffic on the line to mitigate the vibrations emitted during the passage of a train and give the track flexibility in compression in the vertical direction. Such flexibility can also be obtained by means of groove reliefs, present on the bottom of the envelope.
  • the laying in way of this system is carried out in different successive phases: the first phase is the fixing phase of the rail on the support on the one hand and the embedding of the envelope on the support on the other hand.
  • the second phase is the positioning phase of the assembly formed by the rail, the support and the envelope to obtain the desired track layout.
  • the third phase is the sealing phase of the concreting track, which permanently freezes the position of the track.
  • the external dimensions of the concrete blocks can vary substantially from one block to another, particularly because of the shrinkage phenomenon that occurs when the concrete dries and hardens. This variation is problematic when it is desired to replace a defective or damaged support, following a derailment, for example, with another support. Indeed, it is possible that in this case the dimensions of the new support do not allow to enter properly into the cavity left in the cavity of the slab by the old support.
  • the second reason, of an economic nature, is that the concrete supports have a weight such that the transport over long distances presents a handicap in term of cost of transport; a palliative would be to manufacture the supports near the place of installation of the way but that supposes a transfer of know-how and material whose cost is not always compatible with the yard considered, in particular when it comes to the construction of metro lines, because of the size of the yard, or that of a railway line in a country under equipped.
  • the present invention aims to remedy the shortcomings of the existing solutions mentioned above.
  • a rail rail support for slab track comprising a block of molded material whose upper part is provided with rail fastening means, embedded in an envelope comprising a vertical wall and a bottom, said envelope being itself housed in a cavity of said slab, characterized in that said block is molded in a rigid shell forming a lost mold so that the assembly of said block and said rigid shell constitutes a blochet of which the shape and outer dimensions correspond and adapt to the shape and internal dimensions of said envelope, in that said envelope forms a liner and the lower face of the rattle rests on the bottom of said liner.
  • the blocket thus formed can rest directly on the bottom of the liner possibly with the interposition of a relatively flexible sole, if necessary. This guarantees the possibility of replacement of the blochet by simple substitution.
  • one or more reinforcing grids are secured to the rigid shell and embedded in the block of molded material. This makes it possible to avoid the separation of these last two elements in the event of a phenomenon of withdrawal of the molded material during drying.
  • the railway rail support according to a preferred embodiment of the invention is such that the horizontal section of the outer contour of the rigid shell has a curvilinear shape, for example circular. In the latter case, it is advantageous to cut the shell in a circular section tube, metal, preferably steel.
  • the support as shown comprises a block of molded material 1, concrete in the example described, the upper part of which is capable of fastening means 2 of the rail 7.
  • These fastening means comprise an external threaded bolt 3 for to be fixed by screwing into a female element, a kind of peg 4 with internal threading, a spring blade 5 of steel and an elastomer strip 6 having longitudinal grooves to allow flexibility in compression during the passage of the train.
  • the lower part of the rail 7 is held between the upper part of the peg 4 and the elastomer strip 6 by clamping the male element 3 in the female element 4.
  • the spring blade 5 is used to transmit the clamping force on the heel 13 of the rail 7, while distributing the force on a certain surface.
  • This support is embedded in an envelope 8, itself housed in a cavity of the slab 9.
  • the bottom 8a of the envelope 8 has radial grooves 14 intended to provide flexibility in compression to the envelope to attenuate the vibrations emitted when passing a train.
  • the block of molded material 1 is surrounded by a rigid shell 10, a kind of lost mold in which the molding of said block took place. The whole forms a rattle that may need to be healed if the track deteriorates. The rattle rests on the bottom of the shoe.
  • a reinforcing grid 11 secured to the rigid shell 8 is embedded in the block of molded material 1.
  • the end of the rigid shell 10 has a chamfer 12 facilitating its embedding in the envelope 8.
  • the horizontal section of the outer contour of the rigid shell, shown on the figure 2 is circular and obtained by cutting to length of a metal tube, preferably steel.
  • a non-circular curvilinear section could, however, be suitable.
  • the upper end of said rigid shell 10 advantageously has two diametrically opposite notches allowing the passage of the rail 7.
  • the shape and outer dimensions of the rigid shell 10 are adapted to the inner dimensions of the casing 8 and the lower face of the assembly consisting of the concrete block and the rigid shell rest on the bottom 8b of the envelope 8.
  • the bottom 8b is provided with studs 20 integrally molded, which play the same role as the grooves 14.
  • the number and dimensions of these studs can be adapted according to the elasticity that is desired to give the bottom of the liner, on which rests the assembly forming the blocket, constituted by the concrete block 1 and the rigid shell 10.
  • the envelope itself is conventionally made of synthetic material, for example elastomer or the like, as in the case of the previous embodiment.
  • the vertical wall 22 generally cylindrical, has vertical ribs 24 chamfered at their upper ends, which facilitates the introduction and sliding of the rigid shell 10.
  • the edge of the envelope 8 slipper comprises a ring 26 shaped to receive a clamping collar 28.
  • This ring is connected to the rest of the vertical wall by a thinned annular portion 30.
  • the ring 26 is provided externally with segments 32 offset axially and circumferentially and defining between them the housing of the clamping collar 28. The latter makes it possible to seal between the cylindrical outer wall of the rigid shell 10 and the liner, preventing the infiltration of water between these two elements. If, following an incident, it is necessary to replace the rattle, simply remove the collar and extract said rattle vertically by sliding it in the boot.
  • the rigid shell 8 is molded plastic.
  • Clipping means 36 are integrally molded with the rigid shell 10 and projecting therein. The ends of a reinforcing grid 11 can engage in these clipping means, which allows an immediate installation of said grid (no welding is necessary as in the previous example) before pouring the concrete in said rigid shell forming a lost mold.
  • shoe 8 represented at figure 3 can perfectly receive a rigid metal shell like that described with reference to figures 1 and 2 .
  • the rigid shell 10 and the shoe 8 are generally cylindrical with a circular section.
  • a non-circular curvilinear section was possible, preferably any parallelepiped shape, to ensure a better distribution of stresses on the envelope.
  • the horizontal sections of the rigid shell 10 and the shoe 8 have an oval contour, the largest dimension of the support extending substantially perpendicularly to the rail. This advantageous form is illustrated on the figure 5 .
  • the transverse dimension is significantly greater than its height.
  • the transverse dimension will be at least about twice the height.
