Definitions

  • the present invention relates to the assembly of a railway rail on a rigid support and, more particularly, the assembly on a concrete sleeper of a long welded rail.
  • the object of the present invention is to remedy these drawbacks; it allows in particular the use of plastic spacers for the elastic fixing of long welded rails.
  • This invention consists of an elastic assembly of a rail on its support of the aforementioned type in which the leaf spring projects beyond the interlayer at least above the shoe of the rail and comprises at least the longitudinal edge directed towards the rail which, at the loose state, is bent parallel to the rail, so that the concavity is turned towards the shoe of the rail, while, in the tightened state, it is flattened at a slight distance above the rail, the blade being applied in contact with the entire intermediate part which covers the edge of the rail pad.
  • the leaf spring covers the interlayer on the part of the latter which is located directly above the support and can also extend beyond the interlayer beyond said part.
  • the interlayer is protected from the heat of the burners, or the like, by the spring leaf which covers it very particularly above the shoe of the rail.
  • the particular shape of this blade ensures regular and elastic tightening of the interlayer on the pad.
  • the interlayer, on the one hand, and the spring leaf, on the other hand can have characteristic shapes which allow the best results to be achieved.
  • the preferred arrangement of the interlayer is that in which said interlayer has a central body pierced with a hole and two wings, said central body being intended to abut against, on the one hand, the shoe of the rail and, against, on the other hand, a shoulder of the support and said wings being intended to extend for one of them above the shoe and, for the other, above the upper face of the support shoulder.
  • the general shape of the interlayer is essentially trapezoidal; the longer of the two parallel sides of the trapezium is formed by the end of the wing of the interlayer which is designed to rest on the shoe of the rail; the shorter side of the two parallel sides of the trapezoid is the side which rests on the shoulder of the support.
  • this interlayer has a shape resulting from the juxtaposition of a trapezoidal part, the longest of the parallel sides of which is the extreme side of the rail side and the smallest of which parallel sides is located towards the middle of the interlayer and a generally rectangular part which constitutes the most distant part of the rail.
  • This trapezoidal shape of the interlayer is important insofar as, on the one hand, it allows two support points relatively distant from the interlayer on the rail, where it ensures better transmission of lateral forces from the rail during of the passage of trains and where it surprisingly increases the resistance of the rail to the tracking phenomenon.
  • this interlayer is reasonably sized to allow obtaining the results mentioned above; whereas in application of FR-A-1,573,065, the combination of a blade curved perpendicularly to the rail and a corresponding interlayer is used, said interlayer generally had a width (dimension parallel to the rail) of the order of 6 cm, it has been found that the interlayer according to the present application should preferably have a width (dimension of the longest side of the "trapezoid") at least equal to 10 cm and, more particularly, of the order of 12 at 15 cm.
  • the upper face of the interlayer is essentially flat; however, this upper face has, at the rear end of the interlayer (that is to say the end which rests on the shoulder of the cross-member) a groove of open shape and at least one stop.
  • said abutment will be constituted by the fact that the ends of the groove will be closed and that the sides of the rear part of the blade will come to bear against these closed ends.
  • abutment areas have a substantially rectangular shape; as the lengths of the two rectangles are, in the preferred embodiment of the invention, different due to the general trapezoidal shape of the interlayer, this implies that the widths of the two rectangles (in fact the "heights" since, when the interlayer is positioned, these surfaces of the stop are substantially vertical) are different, the width of the stop coming into abutment against the shoulder of the support being greater than the width of the surface coming into abutment against the shoe of the rail. Thanks to this suitable dimensioning of the abutment areas, a better distribution of the stresses inside the interlayer is ensured.
  • the new elastic assembly according to the invention comprises an elastic blade, the shape of which is adapted to the interlayer described above.
  • the blade is provided, in its curved part, with an opening which corresponds exactly to the opening of the interlayer; as previously described, this opening is intended for the passage of a screw, anchored in the crosspiece, screw on which is screwed a nut which has the function of tightening the elastic blade on the interlayer. During this tightening, the blade pressing on two surfaces located at the two ends of the interlayer undergoes a deformation and gradually comes into contact with this interlayer.
  • the interlayer 5 consists of a central body 9 which abuts, on the one hand, on the pad 7 of the rail by the longitudinal edge 22 and, on the other hand, on a shoulder 10 of the support 2 and two wings, one of which comes to rest on the pad 1 of the rail and the other of which follows the shape of said shoulder 10.
  • the insert 5 is shown in FIGS. 2, 3 and 4.
  • this part has the general shape of a trapezoid; it is more precisely constituted by a trapezoidal part 11 and a rectangular part 12; the trapezoidal part 11 is that which corresponds to the wing or rim 22 of the insert 5 which rests on the shoe 1 of the rail; the largest base of this trapezoid constitutes the extreme edge of the interlayer 5 and has a length of approximately 14 cm.
  • the upper face of the interlayer 5 is essentially flat, but comprises towards the rear of this interlayer (the rear being the wing or rim 25 of the interlayer 5 which s' presses on the shoulder 10 of the cross member 2) an open-shaped groove 14; moreover, at the two ends of this groove 14, the insert 5 has two stops (see FIG. 2) 15.
  • Figure 4 shows the general shape of the interlayer.
  • Figures 5 and 6 show that the elastic blade 6 of steel also has a trapezoidal shape; it is made of spring steel and its thickness is generally from 4 to 5 mm approximately; the large base 16 (longitudinal edge 24) of the trapezium will overhang the pad 1 of the rail R while the rear part 17 corresponding to the smallest base of the trapezium will be located above the support; this rear part 17 actually has a cylindrical shape, the lower face 18 of this cylinder fitting exactly over the entire length of its generatrices with the corresponding upper face of the groove 14 of the interlayer 5; the width of this rear part 17 is such that this part of the blade 6 is inserted exactly between the two stops 15 of the interlayer 5; taking into account the positioning described above of the blade 6 with respect to the interlayer 5, the dimensions of the blade 6 are such that said blade 6 projects beyond the interlayer 5 above the shoe 1 of the rail and partially on the sides of the interlayer 5.
  • the blade 6 is bent in the front part 19 and has zero bending towards its rear part 20 located before the groove 14; it therefore takes the form of a portion of ellipsoid. Obviously, the blade has an opening 21 which corresponds to the hole 13 of the interlayer.
  • the rail R is supported by a cross member 2 made of concrete which has a transverse recess 3.
  • This rail R rests on the bottom of the recess 3 by means of a sole 4 made of elastic material, such as rubber, and it is held on the crossmember by fixing devices, such as bolts arranged on each of its sides, between it and the edge of the recess 3.
  • Each of the fixing devices comprises an insert 5 made of a flexible material, such as a plastic material, formed by an elongated body in abutment, on the one hand, against the edge of the recess 3 and, on the other hand, against the edge 23 of the pad 1 of the rail.
  • the body of the insert 5 is extended at its upper part by a longitudinal edge 22, which is supported on the pad 1 of the rail.
  • the interlayer 5 is crossed by a clamping member which, in the embodiment shown, is constituted by a screw 7 which is anchored in the crosspiece 2 and on which a nut 8 is screwed.
  • the upper surface of the interlayer 5, that is to say the opposite face of the nut 8, is covered by a metal fastener cons shaped by a spring-loaded blade 6 arranged parallel to the rail R.
  • the blade 6, which has a rectangular shape, projects beyond the interlayer 5 at least all around the rim 22, that is to say above of the shoe 1 of the rail R.
  • this blade 6 also projects beyond the opposite end of the interlayer 5, above the crosspiece 2 (FIG. 9).
  • the blade 6 is curved parallel to the rail R, at least in its part which is located above the rim 22 of the interlayer 5 and, most particularly, along its longitudinal edge 24 corresponding to its largest dimension. and directed parallel to this rail R.
  • the concavity of the blade 6 is turned towards the shoe 1 of the rail, so that in the absence of tightening the blade 6 takes a configuration similar to that which is shown in FIG. 11, the blade 6 pressing only on the two lateral edges of the interlayer 5.
  • the nut 8 When tightening, the nut 8 flattens the blade 6 and presses it regularly on the upper face of the interlayer 5.
  • the blade 6 is thus kept at a slight distance, on the one hand, from the pad 1 of the rail and, on the other hand, of the cross 2.
  • the blade 6 can be bent over its length and be, for example, constituted by a portion of cylinder whose generatrices are perpendicular to the direction of the rail R.
  • the blade 6 completely covers at least the portion of the interlayer 5 which is located in the recess 3 and above the shoe 1 of the rail R. Consequently, the blade 6 isolates this interlayer 8 from any heating element, such as burners, which could be used during installation. of the R rail to bring it to a temperature above ambient temperature.
  • the fixing device comprises an insert 5 which is extended above the cross-member 2 by a flange 25, similar to the flange 22, for bearing on the shoe 1 of the rail R, and the blade 6 extends above this rim 25.
  • the rim 25 is then provided with an extreme longitudinal rib 26 which forms a stop for the longitudinal edge of the blade 6 furthest from the rail A. The latter is thus immobilized in rotation, which is important, in particular when the nut 8 is tightened on the screw 7.
  • the fixing device ensures, by virtue of the combination of the interlayer 5 with the spring leaf 6 and the particular shape of these two members, an elastic clamping with a bearing surface relatively large on the shoe 1 of the rail R and constant tightening, without any contact, however, of the metal blade 6 with the shoe 1 of the rail, that is to say without risk of wear of the latter and initiation of rupture.
