Definitions

  • the present invention relates to a device for supporting a rail railroad track without ballast and a flange used in as part of such a device.
  • Rail support devices for track without ballast generally include at least one concrete block held by its lower part in an elastic bootie deformable which is immobilized in a mortar bed.
  • FR-A- 2 648 489 already describes a device of this type in which, in addition, the upper edge of the bootie is provided with a collar having a peripheral lip intended to ensure the tightness of the connection between the liner and the mortar bed.
  • the tightening of the upper edge of the liner on the upper part of the block also provides sealing between the liner and said block.
  • the one-piece embodiment does not allow not to adapt the lip to the assembly after pouring and setting of the mortar.
  • the tightening of the liner is effected by means of a external strap surrounding its upper edge. But this provision does not does not allow to obtain satisfactory results as for the sealing and the holding of the block / liner connection.
  • the object of the present invention is to solve these problems techniques satisfactorily.
  • a device for supporting a railroad track without ballast comprising a concrete block held by its lower part in a slipper of elastically deformable material immobilized in a bed mortar, and the upper edge of the liner is provided with a flange comprising a peripheral lip intended to seal the connection between said liner and the mortar bed, characterized in that said collar is produced in the form of an insert comprising snap-fastening means on the liner.
  • Another object of the invention is a collar comprising latching members on said liner and at least one lip device ensuring the seal between the liner and the mortar of wedging.
  • the latching means comprise a rib substantially semi-cylindrical device intended to be housed in force in a corresponding groove on the upper edge of the external lateral face of the liner.
  • said flange is shaped in a closed loop and has elasticity longitudinal.
  • the upper part of said flange has a peripheral bead intended to come into contact of support against the lateral face of said concrete block to ensure sealing the area between said block and the internal face of the slipper.
  • said collar has an internal peripheral conduit in which is housed a clamping element.
  • said peripheral duct is formed in said rib.
  • said sealing lip is pivotable by clicking around an axis parallel to the longitudinal axis of the flange to go from a high position to a low position where its free end comes into bearing contact against the mortar bed and said flange has a shoulder intended to cover the rim slipper.
  • the collar is produced with a elastomeric material and is preferably a different color from that slipper.
  • Yet another object of the invention is a method of production of a rail support for a track without ballast including placing a concrete block in a slipper made of material elastically deformable then pouring a bed of mortar to immobilize the lower part of said liner characterized in that fixed by latching means on the upper edge of the liner prior to pouring the mortar, a flange comprising a peripheral sealing lip so as to ensure the seal between the liner and the mortar.
  • the mortar is poured so that the free end of said lip bears against the upper face of the mortar bed after setting.
  • the device of the invention makes it possible to obtain a sealed connection between the liner and the blocking mortar while strengthening the seal and holding the block / liner connection.
  • the device or the flange of the invention are moreover very easy to manufacture by molding.
  • the support device shown in Figures 1a and 1b is intended for railways without ballast. It includes a concrete block B on which the rail R rests and the lower part of which is held in a shell or liner 1 made of flexible and resilient material deformable. Liner 1 with block B are immobilized in a shim mortar M which is poured after the assembly of block B in the liner 1 leaving the upper edge of the liner above the mortar level.
  • the collar 2 is therefore located above the upper face of the mortar M and is preferably made in the form of a closed loop having a circumferential longitudinal elasticity.
  • the flange 2 has a sealing lip or flap 21 the free end of which is intended to come into contact with bearing against the upper face of the mortar bed after setting so as to isolate from sealingly the connection between the liner 1 and said mortar M is at to be drowned in the mortar bed to create then after its setting a inseparable waterproof connection.
  • Figures 2 and 3 provides according to the invention a flange 2 in the form of an insert comprising fixing means cooperating with retaining means provided on the liner 1.
  • Attaching the collar 2 to the upper edge of the boot 1 is then produced by snap-fastening by means of a groove and of a rib made indifferently one on the liner 1, the other on the collar 2.
  • the upper part of the collar 2 has a shoulder 24 intended to cover the rim 11 of the liner 1 while ensuring also a setting.
  • the shoulder 24 of the flange 2 is provided with a peripheral bead 22 adapted to come into bearing contact against the side face of block B and thus seal the area included between block B and liner 1.
  • the device shown in Figures 4a and 4b corresponds to a production of liner 1 and collar 2 in two separate pieces which are assembled later, as in Figures 1 and 2 but in FIG. 4a, the collar further comprises a peripheral conduit internal 23 in which is housed a clamping element 3 such as a cable or a strap.
  • the internal conduit 23 is formed in the rib 20 to reinforce the tightness of the liner 1 on the block B.
  • the collar 2 is pressed and tightened on the liner by means of the strap peripheral 3 housed in an external peripheral groove 230.
  • the device shown in Figures 5a and 5b corresponds to a making the liner 1 and the collar 2 in one piece which is not in accordance with the invention.
  • the lip 2 is capable of tilt by clicking around an axis parallel to the longitudinal axis of the flange 2 to move from a high position (Figure 5a) to a position low (Figure 5b).
  • FIG. 5a represents the position of the boot 1 before and during the pouring of the mortar M.
  • the lip 21 releases the lower part of the liner 1 so as to allow pouring of the mortar M and its setting.
  • the lip 21 In its low position, the lip 21 is folded down towards the bed of hardened mortar so that its free end comes in sealed contact against the upper face of the mortar M.
  • the bead 22 is inward projection of liner 1 to come into abutment against the face side of block B by transmitting the reaction of the mortar bed M to it on lip 21.
  • the collar 2 will be produced with a color different from that of liner 1.
