Abstract

The invention relates to a splice bar (6), in particular for a buried rail, including a material forming a matrix, and at least one web of fibers (13, 14) extending longitudinally, the shrinkage coefficient of the fiber being lower than the shrinkage coefficient of the thus-formed splice bar and lower than 0.04%/ºK. Such a splice bar is particularly suitable for use in regions having a wide temperature range, in order to, in particular, limit the risk of stray current leakage.

Description

ECLISSES PERMETTANT UNE MEILLEURE ISOLATION D'UN  ECLISSES FOR BETTER ISOLATION OF A
RAIL ENTERRE.  RAIL BURNER.
La présente invention se rapporte à un dispositif pour réaliser une étanchéité le long d'un rail enterré dans un substrat. The present invention relates to a device for sealing along a rail buried in a substrate.
Pour certains véhicules roulant sur rail, notamment les tramways, les rails ne doivent pas constituer un obstacle pour une circulation piétonne ou automobile qui circule sur la même plateforme que celle utilisée par le véhicule sur rail. C'est notamment le cas lorsque cette plateforme est une chaussée routière partagée par un tramway. Les rails sont alors généralement prévus enterrés dans un substrat de cette plateforme, de façon à être affleurant avec la plateforme. For certain vehicles running on rail, in particular trams, the rails must not constitute an obstacle for a pedestrian or automobile traffic which circulates on the same platform as that used by the rail vehicle. This is particularly the case when this platform is a road pavement shared by a tramway. The rails are then generally provided buried in a substrate of this platform, so as to be flush with the platform.
Comme particulièrement illustré par le document F 2 885 372, le rail est de préférence prévu isolé du substrat par un système d'éclisses. Les éclisses assurent notamment une isolation phonique, une isolation électrique et une étanchéité autour du rail vis-à-vis de son environnement. As particularly illustrated in F 2 885 372, the rail is preferably provided isolated from the substrate by a splice system. The splints provide sound insulation, electrical insulation and sealing around the rail vis-à-vis its environment.
La plateforme étant soumise aux intempéries, elle est notamment soumise à de fortes variations de températures, particulièrement dans certaines régions où les amplitudes thermiques peuvent atteindre 40 à 50°C. Les éclisses, soumises à ces variations de températures, en se rétractant longitudinalement, créent entre elles des espaces préjudiciables à l'isolation, notamment à l'étanchéité. Un retrait supérieur à 1% n'est généralement pas acceptable, de la terre, de l'eau ou des graviers, notamment, peuvent s'introduire et créer ainsi des fuites de courants vagabonds. L'invention a pour but de proposer un dispositif d'éclisse, apte à maintenir une isolation satisfaisante le long d'un rail enterré. As the platform is subjected to the weather, it is particularly subject to strong temperature variations, particularly in certain regions where the thermal amplitudes can reach 40 to 50 ° C. The fishplates, subject to these temperature variations, by retracting longitudinally, create between them spaces detrimental to the insulation, including sealing. A withdrawal greater than 1% is generally not acceptable, earth, water or gravel, in particular, can be introduced and thus create leaks of stray currents. The invention aims to provide a splint device, able to maintain satisfactory insulation along a buried rail.
Selon l'invention, une telle éclisse, destinée à isoler un rail de chemin de fer de son environnement, notamment un rail enterré, est caractérisée en ce qu'elle comprend une matière isolante formant matrice, isolante thermiquement et/ou électriquement et/ou étanche à l'eau, et, des fibres disposées et choisies pour conférer à l'éclisse un coefficient de retrait linéaire, mesuré selon la direction longitudinale, inférieur au coefficient de retrait linéaire de la matrice, mesuré selon la direction longitudinale. According to the invention, such a splint, intended to isolate a railway rail from its environment, in particular a buried rail, is characterized in that it comprises an insulating material forming a matrix, thermally insulating and / or electrically and / or water-tight, and, fibers arranged and selected to provide the splice a linear shrinkage coefficient, measured in the longitudinal direction, less than the linear shrinkage coefficient of the matrix, measured in the longitudinal direction.
Avantageusement, les fibres comprennent un ensemble de fibres s'étendant sensiblement longitudinalement dans ladite matrice. Ces fibres peuvent former une nappe, de préférence constituée de deux ensembles de fibres, croisés entre eux. Advantageously, the fibers comprise a set of fibers extending substantially longitudinally in said matrix. These fibers may form a web, preferably consisting of two sets of fibers, crossed with each other.
Dans un mode de réalisation préféré, la matrice est constituée de plusieurs plaques s'étendant longitudinalement et assemblées entre elles, chaque nappe étant assemblée entre deux plaques, chaque plaque étant de préférence disposée verticalement. De préférence aussi, une éclisse comprend au moins deux nappes. In a preferred embodiment, the matrix consists of several plates extending longitudinally and assembled together, each sheet being assembled between two plates, each plate preferably being arranged vertically. Also preferably, a splint comprises at least two layers.
Plusieurs modes d'exécution de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, en référence aux dessins annexés dans lesquels : - La figure 1 est une coupe transversale d'une installation de rail enterré, illustrant un contexte possible de l'invention ; et, Several embodiments of the invention will be described below, by way of non-limiting examples, with reference to the appended drawings in which: - Figure 1 is a cross section of a buried rail installation, illustrating a possible context of the invention; and,
- La figure 2 est une illustration d'un mode de réalisation d'une éclisse selon l'invention, dans le contexte de la figure 1.  FIG. 2 is an illustration of an embodiment of a fishplate according to the invention, in the context of FIG.
La figure 1 illustre un rail 1 enterré dans un substrat 2-4. Le rail est prévu pour y faire rouler les roues 5 d'un train. Le rail 1 est isolé du substrat 2-4 par des éclisses 6-8. Dans l'exemple illustré, le rail est isolé par trois éclisses 6-8, dont le rôle est principalement d'éviter des courants de fuite, le rail 1 étant conducteur. Parmi les trois éclisses, une première éclisse 6 s'étend le long d'un flanc gauche (dans la position de la figure 1) du rail 1, une deuxième éclisse 7 s'étend le long d'un flanc droit du rail et la troisième enveloppe la semelle du rail. Les éclisses ont des formes complémentaires entre elles et avec le rail de sorte qu'elles s'emboîtent entre elles et avec le rail. Les éclisses 6-8 s'étendent longitudinalement - c'est-à-dire perpendiculairement au plan de la figure 1 - le long du rail 1. Chaque éclisse ayant une longueur donnée, elle est prolongée le long du même rail 1 par une autre éclisse du même type, adjacente à la précédente. Figure 1 illustrates a rail 1 buried in a substrate 2-4. The rail is intended to roll the wheels 5 of a train. The rail 1 is isolated from the substrate 2-4 by ribs 6-8. In the example shown, the rail is isolated by three fishplates 6-8, whose role is mainly to avoid leakage currents, the rail 1 being conductive. Of the three splints, a first splint 6 extends along a left flank (in the position of Figure 1) of the rail 1, a second splint 7 extends along a right side of the rail and the third envelope the sole of the rail. The fishplates have complementary shapes to each other and to the rail so that they fit together with each other and with the rail. The fishplates 6-8 extend longitudinally - that is to say, perpendicular to the plane of FIG. 1 - along the rail 1. Each splint having a given length, it is extended along the same rail 1 by another splint of the same type, adjacent to the previous one.
La figure 2 illustre un mode de réalisation pour la première éclisse 6. L'éclisse est constituée d'un matériau en plaque formant matrice, chaque plaque 11 étant disposée verticalement (dans la position des figures 1 et 2) et s'étendant longitudinalement sur la longueur de l'éclisse. Dans cet exemple, l'éclisse 6 est constituée de onze plaques 11 disposées transversalement l'une contre l'autre et assemblées entre elles. FIG. 2 illustrates an embodiment for the first splint 6. The splice consists of a matrix plate material, each plate 11 being arranged vertically (in the position of FIGS. 1 and 2) and extending longitudinally on the length of the splint. In this example, the splice 6 consists of eleven plates 11 arranged transversely against each other and assembled together.
Deux nappes 12 de fibres 13,14 sont disposées entre deux plaques adjacentes. Une nappe est disposée entre la troisième et la quatrième plaque en partant de l'un ou l'autre des côtés de l'éclisse 6. Chaque nappe 12 comprend, d'une part un premier ensemble de fibres 13 disposées sensiblement longitudinalement et, un deuxième ensemble de fibres 14 disposées de façon à relier les fibres 13 entre elles. Two plies 12 of fibers 13, 14 are arranged between two adjacent plates. A web is disposed between the third and fourth plates from one or the other of the sides of the splice 6. Each layer 12 comprises, firstly a first set of fibers 13 arranged substantially longitudinally and a second set of fibers 14 arranged to connect the fibers 13 between they.
Les fibres sont choisies de sorte qu'elles ont un coefficient de retrait inférieur à celui du matériau en plaque. Ainsi, la longueur d'une éclisse contenant une telle nappe 12 varie moins avec la température que la longueur d'une éclisse dépourvue d'une telle nappe. The fibers are chosen so that they have a shrinkage coefficient lower than that of the plate material. Thus, the length of a splint containing such a layer 12 varies less with the temperature than the length of a splice without such a layer.
Les éclisses, notamment les éclisses latérales 6, 7, sont avantageusement en une mousse de matière plastique, par exemple une mousse polyéthylène. Les fibres peuvent notamment être d'une ou plusieurs matières, notamment de polypropylène, de polyamide, polyester et/ou de verre. The splints, in particular the lateral splints 6, 7, are advantageously made of a plastic foam, for example a polyethylene foam. The fibers may in particular be of one or more materials, in particular polypropylene, polyamide, polyester and / or glass.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits. Of course, the invention is not limited to the examples which have just been described.
Ainsi, une nappe peut être constituée d'un seul ensemble de fibres disposées longitudinalement. Elle peut aussi être constituée de deux ensembles croisés et formant l'un et l'autre un angle avec une direction longitudinale, par exemple disposées symétriquement l'un de l'autre par rapport à cette direction. Thus, a web may consist of a single set of fibers arranged longitudinally. It may also consist of two crossed assemblies and both forming an angle with a longitudinal direction, for example arranged symmetrically to each other with respect to this direction.
Grâce à l'incorporation de fibres à faible coefficient de retrait dans la matrice d'une éclisse selon l'invention, on réduit le coefficient de retrait longitudinal de la matrice de sorte qu'il est sensiblement égal au coefficient de retrait linéaire des fibres. De préférence, on choisit les fibres de sorte que le coefficient de retrait longitudinal est inférieur à 0,04% /°K, de sorte que pour une amplitude thermique de 25°K, le retrait longitudinal de l'éclisse est inférieur à 1%. De façon encore plus préférée, on choisit les fibres de sorte que le coefficient de retrait longitudinal est inférieur à 0,02% /°K. By incorporating fibers with a low shrinkage coefficient into the matrix of a splint according to the invention, the longitudinal shrinkage coefficient of the matrix is reduced so that it is substantially equal to the linear shrinkage coefficient of the fibers. Preferably, the fibers are chosen so that the longitudinal shrinkage coefficient is less than 0.04% / ° K, so that for a thermal amplitude of 25 ° K, the longitudinal shrinkage of the splint is less than 1%. . Even more preferably, the fibers are selected so that the longitudinal shrinkage coefficient is less than 0.02% / ° K.
