Definitions

  • the present invention relates to a device for fixing a railway rail on a sleeper.
  • Traditional fasteners include, generally and in particular on each side of the rail, a fastener elastically deformable fixed on said crosspiece by means of a anchor member (stud, lag screw ).
  • This fastener is intended to rest on the skate or base of rail via an interlayer made with an insulating material from a point of electric view.
  • These devices further include a side stop disposed between, on the one hand, the base of the rail which rests, moreover, on an elastic sole and said cross member, on the other hand.
  • the lateral stop transmits the transverse forces from the rail to a shoulder made hollow in the crosspiece.
  • the fastener generally consists of a steel plate with spring with double bending provided with a central opening for the passage of the anchoring member.
  • the two bends are at perpendicular axes to allow elastic deformation by bending.
  • the fastener retains, even after tightening of the anchoring member, a degree of freedom in rotation while the lateral stop has a degree of freedom in vertical translation parallel to the axis of the anchor member.
  • the object of the present invention is to solve these problems techniques satisfactorily.
  • Document WO-A-91/11556 describes a fixing device of a railway rail on a sleeper, comprising a fastener form of elastically deformable plate intended to be fixed on a cross member by means of an anchoring member; an insulating interlayer, the fastener being intended to bear on the base of the rail via said insulating interlayer; and a lateral stop intended to be disposed between the base of the rail, which rests on an elastic sole, and said crosses.
  • the invention provides an improvement to this type of device which is characterized in that said connection is equipped of said insert so as to form an assembly, that said stop side has at least two cavities on its upper face symmetrical about its transverse axis, which are delimited on their lower edge by an inclined face; and that said insert has bosses with complementary profiles integral with the face lower of said interlayer, said cavities being intended to receive said bosses when tightening the fastener thereby forming means for locking in rotation of said fastener and in translation vertical of said stop.
  • the underside of said lateral stop is provided with a housing intended for engagement a tongue secured to the lateral end of the sole.
  • said insulating interlayer is provided with two clips for hanging on the inner edge of the fastener.
  • the inclined faces respectively of the cavities of the stop and the corresponding bosses of the interlayer are parallel two by two.
  • these same inclined faces are separated before tightening of the fastener by a play which depends on the initial bending of the fastener and which are, after tightening, in mutual support contact.
  • the height of the bosses of the interlayer is less than or equal to the depth of the cavities of the stop.
  • angles of the inclined faces of the bosses of the interlayer and the abutment cavities are between 20 ° and 70 °.
  • the device of the invention therefore comprises means for simple and effective blocking and wedging in the form of an interface geometrical between, on the one hand, the fastener equipped with its interlayer insulator and the lateral stop, on the other hand.
  • the special geometry of this interface makes it possible to retain the interlayer, the fastener and the stop in optimal positions during the tightening phase of the organ anchor.
  • the fixing device shown in Figures 1 and 2 is intended to secure a rail R rail on a sleeper T made for example of concrete.
  • This device comprises, on either side of the rail R, a fastener elastically deformable 1 in the form of a steel plate or blade fixed on the cross-member T by means of an anchoring member G such as a stud or lag screw.
  • the fastener 1 is supported on the shoe or base B of the rail R via a insulating insert 2 made, for example, of plastic.
  • the device also includes a lateral stop 3 in material plastic.
  • This stop forming a spacer is disposed between, on the one hand, the base B of the rail R which rests on an elastic sole 4, and the crosses T, on the other hand.
  • the housing L formed in the crosspiece T for receive the rail R is hollowed out delimiting shoulders lateral and if necessary, as shown in FIG. 1, a support surface inclined at an angle a to a plane horizontal whose value is a few degrees.
  • the lateral stop 3 has on its underside, a housing 33 in which is engaged a tongue 43 secured to the lateral end of the sole 4 (see figure 5).
  • the tongue 43 extends only over the portion of the sole located facing the fixing device.
  • the lateral stop 3 has on its upper face at least two cavities 31, 32 intended for receive when tightening the fastener 1 bosses 21,22 with profiles complementary to the underside of the interlayer insulator 2.
  • the stop 3 has more than two cavities.
  • the cavities 31.32 as well as the corresponding bosses 21.22 are symmetrical with respect to the respective transverse axes of the stop 3 and tab 2.
  • Each cavity 31.32 is delimited on its inner edge by a inclined face 31a, 32a.
  • each boss 21, 22 has a lateral face. inner 21a, 22a which is inclined, so that the side faces respective interior of the cavities 31, 32 of the stop 3 and the bosses 21.22 of the interlayer 2 are substantially parallel two by two.
  • the inclinations of these faces is understood between 20o and 70o.
  • the bosses 21, 22 are carried by arms 2a extending towards the rear of the interlayer 2 in moving away from the rail R.
  • the interlayer 2 is provided with two clamps 20 in U ensuring attachment to the front edge of the fastener 1.
  • the stop 3 has a profile substantially square with a side 3a which is arranged in contact with the internal lateral wall in the shoulder of the housing L of the cross member T reserved for the rail R.
  • the upper side 3b of the stop 3 has a circular cutout 30 allowing its axial positioning in front of the clamping member G.
  • Figures 4a and 4b show views in partial section of the device of the invention, according to the plane CC of FIG. 1.
  • the progressive reduction in clearance J is also accompanied by a correct repositioning of the fastener 1 which is oriented and moved automatically rotating around the axis of the clamping member.
  • This interlocking blocking is also resiliently maintained thanks to the spring effects produced by the fastener 1, and the sole 4 arranged under the rail.
