Definitions

  • the railway consists of rails fixed on sleepers placed perpendicular to the rail, said sleepers rest on a thickness of stones called ballast.
  • This traditional concept of track has been very successful and has demonstrated its perfect adaptation to various types of rail traffic.
  • ballast-free track is then used, the base of which is made of concrete to replace the bed of stones.
  • a particularly widespread embodiment of track without ballast comprises as shown in Figure 1 a cross member consisting of two concrete blocks or blocks connected together by an angle called a spacer.
  • the shape of the lower part of the concrete blocks is designed to perfectly adapt to the shape of an enveloping elastomer shell which is called a liner.
  • an elastomer sole Between the underside of the concrete block and the bottom of the envelope is generally disposed an elastomer sole, the surface of which is substantially equal to the surface of the underside of the block.
  • This sole has a flexibility adapted to the nature of the traffic on the line and gives the track an elasticity in the vertical direction replacing or improving the elasticity provided by the ballast of traditional design.
  • the side walls of the envelope are provided with grooves type reliefs which provide a certain elasticity in the horizontal plane.
  • a bead arranged over the entire contour, allows the envelope to hold correctly on the concrete blocks, avoiding excessive yawning.
  • the assembly consisting of the rails and the sleepers connected together by a fixing system, is positioned in space using wedging devices and a so-called mortar is poured. timing coming to fix the track in a geometrical position determined once and for all.
  • the mortar is poured to a height slightly lower than the level of the lower edge of the liner bead; the lower part of the envelope is then surrounded by mortar, forming a cell-shaped housing.
  • This type of track without ballast is mainly used for applications in tunnels, for metropolitan networks or for conventional lines of rail networks where trains run at speeds below the high speed range whose lower threshold can be located approximately at 200 km / h.
  • This lifting can be critical if its amplitude is such that a clearance between the block and the sole or between the sole and the bottom of the envelope can take place, it can then result in a shock during the downward movement of the block when the game is canceled.
  • the invention which is the subject of the patent therefore aims to provide a solution to this problem which has not yet been solved to date.
  • particular devices have been designed so as to elastically fix the cross member in the vertical direction by exerting a restoring force downwards when the cross member tends to lift.
  • This elastic connection completes the elastic connection provided by the sole to form a bilateral elastic connection.
  • a support device for a railroad track without ballast comprising at least one concrete block resting on a flexible sole; the assembly being held in a shell of elastomeric material which is anchored in a concrete bed by enveloping the lower part of said block and the upper edge of which is provided with a bead, characterized in that the horizontal section of said block is variable and has a maximum surface at a level located immediately under the bead of the upper edge of the shell so as to limit the relative displacement of the block and the shell by an elastic retainer.
  • the horizontal section of said block is variable by modifying its width.
  • the thickness of the bead is variable along the upper edge of said shell.
  • the internal lateral walls of the shell are provided with horizontal grooves intended to cooperate with corresponding grooves formed on the lateral face of the lower part of said block.
  • said bead further comprises a clamping member on the upper part of said block.
  • the external lateral walls of said shell are provided with peripheral projections to strengthen the anchoring in the mortar bed.
  • the traditional rail support device shown in FIGS. 1a and 1b comprises a cross member made up of two concrete blocks or blocks 2,3 arranged symmetrically and, optionally, connected by an angle or spacer 4 and on which the rails R1 and R2 rest. .
  • the blocks 2,3 rest on a flexible sole 10 and the block / sole assembly is placed in a shell or liner 5,6 of elastomeric material which envelops the lower part of said block and the upper edge of which is provided with a bead 8 .
  • the shell 5.6 is anchored and embedded up to the level of the bead 8 in a bed of mortar B.
  • FIG. 2 shows a detailed sectional view of the assembly consisting of the block 2 and the shell 5 shown in Figures 1a, 1b.
  • the internal face of the lateral wall of the shell 5 is advantageously provided with grooves or cells 7 intended to cooperate with corresponding grooves formed on the lateral face of the lower part of the block to reinforce the holding of said block 2 by suction effect. and ensure a certain elasticity in the horizontal plane.
  • Figures 3a and 3b show an embodiment of a concrete block used in the device of the invention.
  • the block 12 has a different geometry from the blocks 2 and 3 previously described. Starting from the base upwards, the horizontal section of the block has a variable surface which increases first of all to reach a maximum situated at a level which is immediately below the bead of the upper edge of the shell so as to limit the relative displacement of the block and the shell by an elastic retainer.
  • the shell 15 has a height such that once the block in place in it the upper edge of the envelope is located above the contour where the surface of the horizontal section of the concrete is maximum but the width of the empty shell is such that it is then necessary to elastically deform its upper edge in order to make it pass above the level where the width of the block is maximum.
  • this characteristic is obtained by making the block with a variable width; the lower part 12a being with diverging side faces while the upper part 12b is with converging side faces.
  • the shell 15 firmly and tightly envelops the block 12 by retaining the bead 18 above the divergent side faces.
  • the bead 18 comprises a tightening member, for example a strap 19 which comes to press the bead 18 on the walls of the block 12.
  • This plating will be all the more effective as the thickness of the bead will be variable along the upper edge of the hull to obtain a suitable pressure distribution on the contour.
  • Figure 4 shows a top view of a section of the shell in a horizontal plane located at the height of the bead.
  • the clamping device can be incorporated into the envelope during molding thereof and will therefore act inside the material in the manner of a spring.
  • an elastic clamping member cord .
  • block and shell shell become integral when the clamping device is in place.
  • the clamping device encloses the block at a place where its section in a horizontal plane decreases, which consequently blocks any relative upward movement between block and envelope.
  • the side walls of the lower part of the shell are provided with peripheral projections 15a.
  • projections have a suitable geometry to strengthen the strength of the anchoring of the envelope in the concrete and to avoid any separation of the block-envelope assembly from the housing in the form of a cell in the concrete: figure illustrates the area of attachment of the envelope in the concrete.
