Definitions
- the present invention relates to a type of cross member system comprising a cross member having a lower face, and an upper face for receiving a rail fastening system, and a shell.
- transom any type of piece of wood, metal, concrete, placed perpendicular to the railway, and intended to serve as a support for the rails, to maintain the spacing while distributing the loads. It can thus be a monobloc cross-member supporting two rails of the two rail wires, or a two-block crossbar comprising two blocks, each blochet supporting a rail of one of the rail wires, the two blocks being secured or not by a spacer.
- the document FR2906269 A1 discloses a system of the aforementioned type, in which, as shown on the figure 1 , the hull forms a liner 6 delimiting a receiving housing of the lower portion of the cross member 12, made of concrete.
- the bottom of the liner 6 is provided with an elastic sole 17 on which rests, completely or partially, the crosspiece 12.
- the system is supplied assembled on the construction site of the railway. It is held in position suspended from the rails the time of pouring the concrete of a support raft of the way. Once the concrete is taken, the system is wedged in position. If the liner is secured to the raft, the crossmember can move slightly and elastically compared to the shoe, thanks to the sole 17. This allows the absorption of vibrations when passing vehicles.
- a gasket 8 or more generally a gasket member is provided between the upper edge of the peripheral wall of the liner 6 and the side walls of the crosspiece 12. This seal serves to prevent the water or fine particles do not infiltrate inside the liner, between the boot and the crossbar, likely to block the possibility of movement of the cross.
- the laying of this joint is a step in the manufacturing process of such a system that requires manpower. This results in a high cost of the system obtained and a quality of implementation of the seal which depends on the operator.
- a cross member having a housing enclosing a concrete block reinforced with reinforcing beams.
- the housing consists of a lower part and an upper part, glued to each other.
- the upper face of the housing receives a plate fixed by tie rods, which pass through the upper part and are anchored in inserts housed inside the beams.
- the upper part is sandwiched between the cross member and the rail support system.
- the invention therefore aims to solve these problems.
- the subject of the invention is a system and a section of railroad track according to the appended claims.
- a system 10 comprises a cross member 12, a hull 13 and a rail fastening system 14.
- the crossbar 12, rigid, is made for example of concrete. It has, in the embodiment shown, a substantially parallelepiped shape.
- the crosspiece 12 thus has a lower face 20, an upper face 22 and four lateral faces 21 connecting the lower and upper faces between them.
- the upper face 22 of the rigid cross member 12 comprises a zone 23 for the implantation of the rail fastening system 14.
- this zone 23 is constituted by the bottom of a recess, of substantially square, for receiving a metal plate forming the base 41 of the rail fastening system 14.
- the rail fastening system 14 maintains a rail 15 in position on the crosspiece 12.
- the rail fastening system 14 comprises lag bolts 42, 43 screwed into the cross member 12 to fix the base 41 on the latter.
- the base 41 is a rectangular-shaped plate having a width less than that of the cross-member 12 and a thickness substantially equal to the height of the recess defining the implantation zone 23 of the system 14 on the cross-member 12.
- a plate is generally metal, but rigid plates of composite material are now available on the market. It is interposed between the rail 15 and the cross 12.
- the rail fastening system is thus called indirect fastening system.
- the rail fastening system 14 also comprises a pair of fasteners 44, 45 allowing, by screwing the lag screws 42, 43, to wedge the pad of the rail 15 between the fastener and the base.
- the two fasteners 44 and 45 are placed on either side of a transverse plane of the railway and median of the crossbar 12.
- the fastener holding the rail can be fixed other than by the retaining lug of the base.
- the shell 13 substantially completely envelops the cross member 12 so as to define an interior receiving volume of the cross member 12 which is impervious to external aggression.
- the shell consists of the vertical assembly of two half-shells.
- the lower half-shell is called slipper and the upper half-shell is called cowl.
- the liner 16 is shaped to receive the lower portion of the cross member 12.
- the liner 16 has a bottom 60, substantially flat, and a peripheral wall 61, which rises from the bottom 60 and ends with a flange 63 free.
- the cover 18 is shaped to cover the upper portion of the crosspiece 12.
- the cover 18 has a ceiling 82, substantially plane, and a peripheral wall 81, which falls from the ceiling 82 and ends with a flange 85.
- the rim 85 is provided with a flange 86 largely covering the rim 63 of the liner. This makes it possible to strongly limit, if not totally, the entry of water or dust into the interior volume delimited by the shell 13.
- the collar 86 makes it possible to secure the cover 18 to the boot 16 by snap-fastening.
- the shell formed by the liner and the hood defines a sealed protective volume of the rigid cross member 12.
- the boot and the hood have a certain rigidity.
- the cover 18 and the liner 16 are for example made by thermoforming a suitable plastic material, for example polyvinyl chloride, also called PVC, or acrylonitrile butadiene styrene, also called ABS.
- the system 10 does not include a seal between the flange 63 of the liner 16 and the lateral faces 21 of the crosspiece 12.
- the cover 18 is secured to the cross member 12.
- the ceiling 82 of the cover 18 is held between the base 41 of the rail fastening system 14 and the crosspiece 12. More specifically, the ceiling 82 of the cover 18 comprises a recess 83, conjugate of the recess defining the implantation zone 23 of the system 14. In this withdrawal 83, through holes are provided to allow the insertion of lag screws 42 and 43 for fixing the system 14 on the crossbar 12. The maintenance is relatively easy since it is sufficient to separate the system of mounting rail 14 of the cross member 12 and remove the lag bolts 42 and 43 to release the cover 18, which, once detached from the shoe 16, can be replaced.
- the hull-through system 10 comprises a resilient soleplate 17 interposed between the bottom 60 of the liner 16 and the lower surface 20 of the cross member 12. More preferably, a plurality of resilient segments 19 are interposed between the peripheral wall either slipper 16 is the hood 18 and the side faces 21 of the cross member 12.
- the sole 17 and the segments 19 allow the absorption of vibrations at the passage of trains.
- the hull has a relative stiffness allowing it to follow the deformations of the cross member 12.
- a seal is held in compression between the flange 85 of the peripheral wall 81 of the cap 18 and the flange 63 of the peripheral wall 61 of the liner 20.
- the cover 18 is fixed to the shoe 16 by riveting their edges.
- FIG 3 a second embodiment of a transom system is shown, which corresponds to the invention.
- an element identical to an element of the figure 2 is identified by the reference number used to locate this corresponding element on the figure 2 , while a similar element is spotted by the reference number used to locate this corresponding element increased by a hundred.
- the rim 163 of the peripheral wall 161 of the liner 116 comprises a plane portion 162 inclined outwards, a substantially horizontal edge 165 and a fallen flange 166.
- the flange 185 of the peripheral wall 181 of the cover 118 is intended to cooperate with the flange 163 of the peripheral wall 161.
- the portion redan 187 has an outer face 188, intended to be applied against the flat portion 162 of the edge 163 of the liner 116. It therefore has an inclination identical to that of this flat portion 162.
- the outer face 188 is provided with a groove, which is open towards the flat portion 162. This groove is intended to receive a seal 190.
- the seal 190 is deformed by compression.
- the redan conformation of the flange 185 allows, by acting on the elasticity of the material which is constituted by the cover 118, to apply a suitable compression force.
- the edge 184 is intended to be applied against the edge 165.
- rivets 195 are regularly disposed over the entire periphery of the shell. These rivets are inserted into holes provided on the edges 184 and 165.
- the flanged flange 186 is intended to cover widely the fallen edge 166.
- the ceiling 182 of the cover 118 comprises a light 183.
- the outline of the light 183 is bent inwards so as to cooperate with the edge of the recess defining the implantation zone 23 of the fastening system. of rail 14.
- the outline of the light 183 is shaped to engage a groove, and for example the edges of a groove, provided on the upper face of the groove. 12 crosses around the area 23 of implantation of the rail fastening system 14.
- the groove corresponds to the recess mentioned above.
- the liner and the hood are made of a rigid material.
- the liner and the cover are made of a flexible material, for example rubber.
- the liner and the bonnet are two separate parts made independently of one another and then combined to form the waterproof shell.
- the boot and the bonnet forms a single piece, made of material, constituting the hull substantially completely enveloping the sleeper.
- the shell is then made of a flexible and elastic material allowing, by deformation, to introduce the cross member inside the shell.
