Definitions

  • the invention relates to a flange that allows the joining of the ends of two attached rails. This union is temporary while the works prior to the welding of the rails are carried out to form the track.
  • sections of rails of a certain length are spliced, for example 270 m, which are subsequently welded. Before welding them, it is necessary to perform a certain type of work on the track, such as batting the ballast, for which the sections must remain joined by joining flanges.
  • connection flanges are known in the state of the art, however they do not offer a guarantee of adequate bonding and stability during the performance of the work on the track, especially during the performance of the batting. This is due to the fact that the known devices make a connection of the adjacent rails in the area of the rail skate, this area of the rail being in the area of influence of the bats.
  • the joint flange object of the invention ensures relative stability between the ends of the rails that are joining while allowing the track assembly operations prior to the welding of the rails to overcome the disadvantages described above.
  • Each stabilizer pieces each adapted to be located longitudinally to both rails to join. Said pieces comprise an upper internal surface and a lower internal surface adapted to be in contact with the root of the head and the root of the skate of the rails to be joined. The surface of the head and the skate next to the soul of the rail are understood as root.
  • a first and a second clamping element each can be placed on one of the rails to be joined in contact with the external face of both stabilizer pieces and intended to press both stabilizer pieces towards the rails to be joined.
  • the stabilizer parts hold e! lane in the area of! soul, zone that is not in the zone of influence of the batting works.
  • the support is carried out by the root of both its head and its skate so that both rails remain united in a stable way and without pitching during the work done on the track.
  • Figure 1 shows a cross section of an exemplary embodiment of the joint flange object of the invention.
  • Figure 2 shows an elevation view of the connecting flange of the embodiment example of Figure 1.
  • FIG. 1 An embodiment example of the flange object of the invention is shown in figures 1 and 2, more specifically in figure 1 both stabilizer parts (1 1) with their upper (12) and lower (13) internal surface located in contact with the root (5) of the head (2) and with the root of the base (6) of the skate (4) of one of the rails (1) to be joined.
  • the upper (12) and lower (13) internal surface of the stabilizer parts (1 1) comprise a decreasing section towards the core (3) of the rail (1) antagonistic to the section of the root of the head (2) and of the skate (4) so that the stabilizing parts (11) and the rail (1) have a wide contact surface and also by increasing the tightening of said stabilizing parts (1 1) against the rail (1) the interlocking thereof (1 1) and said contact surface is increased.
  • FIGS 1 and 2 are also shown one of the clamping elements (14) therefore linked to one of the rails (1) to be joined.
  • the clamping element (14) is in contact with the outer face of both stabilizer parts (11) and presses both stabilizer parts (11) against the rail (1). More specifically, the clamping element (1 1) is located on the outer face of both stabilizer parts (11) at the height of the core (3) of the rail (1) in two recesses (18) for the accommodation of two projections (19 ) of the clamping element AND!
  • Clamping element (14) comprises an extension that embraces the skid (4) of the rail (1) and therefore surrounds it (4). Alternatively, the clamping element (14) could have an extension that would hug the head (2) of the rail (1).
  • the clamping element (14) comprises two symmetrical parts (15, 16), each of them in contact with one of the stabilizing parts (11) and therefore pressing it (11 ) on the rail (1).
  • a clamping screw (17) which, in the example of embodiment shown, crosses both symmetrical parts (15, 16) through the bottom of the rail (4) of the rail ( one).
