Definitions

  • the present invention relates to the field of railway infrastructure, in particular track materials, and relates to an assembly formed by a concrete slab and a cross member for composite material tracks and track apparatus.
  • the sleepers used in applications laid on concrete slabs are generally made of prestressed concrete or not and are provided with a central longitudinal groove, allowing the insertion of bolts for the attachment of track elements, such as as saddles, attachments, insulators, support stops and other elements of a switchgear.
  • sleepers known to date are laid and poured into a concrete slab and are therefore not stressed in bending.
  • Such sleepers are known in particular by FR-A-2,482,990 and allow to meet all the mechanical requirements. For this purpose, they have a height of the order of 180 mm to 190 mm, to ensure good mechanical strength, by the insertion of prestressed elements or not and in particular because of the longitudinal longitudinal groove.
  • sleepers require the realization of an important disbursing during installation, to take into account their height.
  • the sleepers thus produced prestressed concrete or not, have a very high density, resulting in unit weights of sleepers between 100 Kg and 450 Kg, so it is necessary to implement handling means and the transport of these sleepers is relatively expensive.
  • sleepers are still poured into a concrete slab, so that a realization of heavy and bulky sleepers is not necessary.
  • the metal profile is embedded in the concrete, it is electrically connected to the ground, so that it allows a propagation of stray currents generated by the return of the traction current of the rails.
  • CH-A-447242 a monolithic crossbar, in which the prestressed concrete is replaced by a molded synthetic material provided with a reinforcing reinforcement. Such an achievement is comparable to that of reinforced concrete sleepers. As a result, this cross is massive and comparable in weight to wooden sleepers or concrete and is also intended to be used on conventional railways, that is to say with ballast.
  • the present invention aims to overcome these disadvantages by proposing an assembly incorporating a concrete slab and a crossing for track and track apparatus, low height, low weight and providing total electrical insulation between two rails.
  • the crosspiece for track and switchgear provided with a longitudinal central groove for securing fastening of rails, saddles, insulators, support-stops or the like, this crossbeam being embedded in a slab concrete and being provided with bolts for fixing a track rail, for example with the interposition of a saddle and implementation of toads, is made in the form of a profile made of a composite material.
  • FIG. 1 of the accompanying drawings shows a cross-piece 1 for track and track apparatus, provided with a longitudinal center groove 2, for attaching fasteners for rails, saddles, insulators, support-stops or the like.
  • a crossbar 1 is implemented for fixing a track rail 3, is embedded in a concrete slab 4 and is provided with bolts 5 for fixing said rail track 3, for example with the interposition of a saddle 6 and implementation of toads 7.
  • this crossbar 1 is made of a composite material.
  • the composite material is a pultruded composite material.
  • Such a composite material is constituted by a resin matrix surrounding a reinforcement composed of fibers.
  • the resin used is of the polyester, epoxy, phenolic or thermosetting type and the fibers are glass, mineral, vegetable or aramid fibers.
  • the materials thus obtained have excellent mechanical characteristics and, in particular, a very high strength-to-weight ratio.
  • the fiber reinforcement provides the mechanical strength, namely the tensile strength and rigidity, the tensile modulus in the direction of the fibers being greater than those of the steel.
  • the resin matrix binds the fibers forming the armature and distributes the compression or bending forces, while providing chemical protection and electrical insulation.
  • the embodiment of the cross-member 1 by pultrusion makes it possible to obtain the optimum mechanical properties of a composite material, which is, by definition, anisotropic, by preferential orientation of the reinforcing fibers. Indeed, during pultrusion, the reinforcing fiber layers are arranged in the directions of mechanical stress, so that the product obtained is perfectly suited to the intended application.
  • the method of producing the crossbar 1 is of known type and does not require a detailed description. It suffices to recall that a fiber reinforcement impregnated with a thermosetting resin is pulled through a die mold, in which shaping and crosslinking takes place. Such a method makes it possible to obtain profiles of great length and of all shapes, these profiles being cut to predetermined lengths, at their exit from the die mold.
  • the height of the crossbar 1 can be very significantly reduced compared to the height of conventional sleepers prestressed concrete or not, namely to have a height of the order of 80 mm, so that for the installation of such sleepers, the civil works are very significantly reduced, allowing a significant saving on the volume of the concrete slab, in which the crossbar is inserted. This results in substantial gains on the site, both in terms of the duration of the work and the costs of the latter.
  • the cross member according to the invention in a reduced footprint, its weight is very significantly reduced, namely of the order of eight kilograms per linear meter.
  • Such a reduction in weight and space, compared with a concrete crossbar, whose weight per linear meter is approximately 90 kilos, facilitates handling operations, both during the blank assembly at the factory and during assembly on site and thus the implementation without special lifting tools, such as bridges or forklifts.
  • the precise placement of sleepers during assembly no longer requires handling tools and is therefore easier, while allowing a faster and more accurate installation, the adjustment of sleepers being possible manually.
  • on-site transportation and storage are facilitated.
  • the composite cross member is also an electrical insulator and the insulation problems of one rail relative to the other and the insulation of the railway, usual to this day, are completely eliminated.
  • the embodiment of the cross member 1 composite material because of the embodiment of the cross member 1 composite material, it is completely insensitive to corrosion, unlike metal profiles used in the known prestressed concrete sleepers.
  • the mounting of the track rails 3 no longer requires the use of additional electrical insulating devices, such as those provided with the traditional crosspieces, namely insulating insoles. , insulating guns and insulating washers.
