Definitions

  • the present invention relates to a device for fixing a rail on a concrete slab without ballast comprising a metal saddle having a counterbore intended to receive the rail and resting on an elastic sole resting itself on a metal base resting on the concrete, with possible interposition of an insulating sole, means for fixing the base to the concrete, means for fixing the metal saddle to the base and means for fixing the rail to the saddle.
  • the present invention aims to simplify known metal base and saddle devices while retaining, or even improving, the elastic characteristics of the binding, in particular the dynamic track module.
  • the fixing device is characterized in that the means for fixing the saddle to the base and the means for fixing the rail to the saddle are common and constituted by flanges, known per se, consisting of a rod having a vertical rectilinear part provided with a heel which hooks into the base and a wavy curved part making a spring, the end of which pinches the shoe of the rail after being stretched, by rotation, on a ramp of the saddle, and having an intermediate point bearing on the base and substantially opposite the end bearing on the shoe of the rail.
  • Two flanges are thus sufficient to fix the metal saddle on the base and the rail on the metal saddle, while in the previous device sixteen elements are necessary, without counting the additional elastic washers.
  • the intermediate fulcrum of each fixing flange rests on a pillar secured to the base and passing through the elastic sole and the metal saddle, so that the intermediate support of the clamp is not subject to the vertical movements of the saddle due to vertical vibrations during the passage of a train, displacements which would tend to spread the intermediate support point of the saddle if the clamp rested on saddle.
  • the elastic sole is honeycombed on its two faces, the alveoli being arranged so that the elastic sole has in the middle part of its thickness a continuity transverse to the rail, except in the places crossed by the pillars of the base, so as to ensure effective damping in the vertical plane while having a high resistance to horizontal shearing forces.
  • the device shown in Figures 1 and 2 essentially comprises a metal base 1 of rectangular shape, a metal saddle 2, a rubber midsole 3 and two flanges 4 and 5 simultaneously maintaining a rail 6 on the saddle 2 and this saddle on the base 1.
  • the base 1 is fixed to a concrete slab 7, with the interposition of an insulating sole 8, by means of two lag screws 9 and 10 screwed into sheaths 11 and 12 embedded in the concrete.
  • the lag bolts 9 and 10 as well as the sheaths 11 and 12 form the PLASTIRAIL (registered trademark) process as described in patent FR 2 636 685.
  • the upper face of the base 1 has a countersink 13 inclined transversely, the device shown being intended to fix a rail in a curve.
  • the elastic sole 3 is retained laterally by the edges of this counterbore.
  • the flanges 4 and 5 are SYRESCA (registered trademark) flanges as described in patent EP O 373 099.
  • the flange 4 has a straight part 41, a heel 42 at its lower end, an upper part 43 in the form of a wavy spring. the end 44 of which rests on the heel of the rail 6 and the intermediate point of which bottom 45 rests on a column 14 of the base 1, column passing through the elastic sole 3 and the saddle 2.
  • the flange 5 is identical to the flange 4, the corresponding parts being designated by 51 to 55.
  • the intermediate support 55 rests on a second column 15 of the base 1.
  • This base 1 has oblong holes 16 and 17 for the passage of the heels 42 and 52 of the flanges when they are put in place.
  • the metal saddle 2 has two ramps 18 and 19 extending respectively on either side of the columns 14 and 15 and the upper end of which is at the level of the shoe of the rail 6. These ramps serve to tension the flanges as described in EP 0 373 099.
  • the metal saddle 2 also has two platforms 22 and 23 parallel to the base of the saddle, at the same level as the columns 14 and 15 and serving to support the intermediate support points 45 and 55 during the rotation of the flanges 4 and 5.
  • the saddle 2 also has a counterbore 20 in which is housed the shoe of the rail with the interposition of a sole 21 of synthetic material rising on each side of the shoe of the rail.
  • Eccentric adjustment washers 24 and 25 make it possible to adjust the position of the base 1 on the concrete slab.
  • two pairs of oblong holes could be provided.
  • the flanges 4 and 5 are put in place as described in patent EP O 373 099, that is to say in a position turned 180 ° relative to the position shown. They are then turned slightly to hang their heel in the base with a certain tension due to the rise of the ends 44 and 54, the flanges on the ramps 18 and 19 and the compression of the elastic sole. 3.
  • An assembly is thus obtained composed of the base 1, the elastic sole 3, the saddle 2 and the flanges 4 and 5, an assembly which can be handled and transported as a monolithic element.
  • the rail 6 After being fixed to the concrete slab by means of lag screws 9 and 10, the rail 6 is put in place and fixed by rotation of the flanges 4 and 5.
  • the elastic sole 3 can have different structures.
  • An advantageous structure is shown in Figures 3 and 4.
  • the sole shown is cellular, that is to say that it has on its two faces substantially rectangular cells or cavities and of three different dimensions 26/27, 28, 29 /30.
  • the cells 29 and 30 are elongated in a direction transverse to the rail.
  • the sole has cutouts 31, 32, 33, 34 for the passage of the columns 14 and 15 and the flanges.
  • the sole therefore has a continuous core 35 except at the location of the cutouts. This core provides the sole with good resistance to shear forces acting parallel to the sole, while the cells of these two faces provide good vibration damping in the vertical direction. This meets the requirements.
  • the upper face of the base 1 will of course be flat or of a different inclination depending on whether the device is intended to fix the rails in a straight part or in a curve of different radius.
