TRAVEE POUR VOIE FERREEWORK FOR RAILWAY
La présente invention concerne une travée pour une voie ferrée, que le matériel roulant soit sur pneumatique ou sur rail. En effet, dans la présente demande, on appelle voie ferrée non seulement une voie ferrée en tant que telle, c'est-à-dire une voie avec des rails sur lesquelles roulent un matériel roulant, mais également une voie avec piste de roulement, c'est-à-dire une voie pour du matériel roulant sur pneumatique, du type métro sur pneumatique. The present invention relates to a span for a railway, whether the rolling stock is on a tire or rail. Indeed, in the present application, the railway is called not only a railroad as such, that is to say a track with rails on which a rolling stock rolls, but also a track with a track, that is to say, a track for rolling stock on pneumatic, metro type on the tire.
On connaît une telle travée du type formée par une structure en forme de U définissant une portion de trajectoire du matériel roulant, la structure en U comprenant une dalle porteuse supportant la voie ferrée et deux parois latérales sensiblement verticales. Such a span of the type formed by a U-shaped structure defining a portion of trajectory of the rolling stock is known, the U-shaped structure comprising a bearing slab supporting the railway track and two substantially vertical side walls.
La trajectoire de la voie ferrée est définie par l'assemblage des différentes structures en U les unes le long des autres. Parmi ces structures en U, certaines, en béton, ont été préfabriquées hors site, et leur assemblage facilite considérablement la réalisation de la voie ferrée. Cependant, les structures en U préfabriquées ne permettent de simplifier que la réalisation du gros uvre. The trajectory of the railway is defined by the assembly of the various U-shaped structures along each other. Some of these U-shaped structures, made of concrete, have been prefabricated off-site, and their assembly considerably facilitates the construction of the railway. However, the prefabricated U-shaped structures make it possible to simplify only the realization of the large work.
La présente invention vise à réaliser une travée comprenant une structure en U du type précité permettant la simplification de l'intégration de différents éléments de finition. The present invention aims to achieve a span comprising a U-shaped structure of the aforementioned type for simplifying the integration of different finishing elements.
Selon la présente invention, la travée comporte, d'une part, une structure en U du type précité, et d'autre part, au moins un rail latéral disposé latéralement à la voie, au moins une paroi latérale de la structure en U portant au moins un rail latéral, la structure en U étant dimensionnée de sorte que chaque paroi latérale portant un rail latéral supporte les efforts transversaux et verticaux que le matériel roulant génère. According to the present invention, the bay comprises, on the one hand, a U-shaped structure of the aforementioned type, and on the other hand, at least one side rail disposed laterally to the track, at least one side wall of the U-shaped structure carrying at least one side rail, the U-shaped structure being dimensioned so that each lateral wall carrying a lateral rail supports the transverse and vertical forces that the rolling stock generates.
Ainsi, en dimensionnant correctement la structure en U, l'installation de rails latéraux, comme celui d'arrivée de courrant électrique ou celui de retour du courrant permettant l'alimentation électrique du matériel roulant, ou encore, dans le cas de matériel roulant sur pneumatique, comme le rail latéral de guidage, peut se faire directement sur les parois latérales de la structure en U, ce qui permet de se dispenser des organes de support habituellement utilisés, telles que des tiges verticales fixées à la dalle porteuse (sur chantier) et supportant ces rails latéraux. Ainsi, la présente invention permet de diminuer les coûts liés à l'installation des rails latéraux D'autres particularités et avantages de la présente invention apparaîtront dans la description qui va suivre de deux modes de réalisation donnés à titre d'exemple non limitatif et illustrés par les dessins mis en annexe. Thus, by properly dimensioning the U-shaped structure, the installation of side rails, such as that of electric current flow or that of return of current for the electrical supply of rolling stock, or, in the case of rolling stock on pneumatic, as the lateral guide rail, can be done directly on the side walls of the U-shaped structure, which makes it possible to dispense with support members usually used, such as vertical rods attached to the load-bearing slab (on site) and supporting these side rails. Thus, the present invention makes it possible to reduce the costs associated with the installation of the lateral rails. Other features and advantages of the present invention will appear in the following description of two embodiments given by way of non-limiting example and illustrated. by the drawings appended.
La figure 1 est une vue en coupe de deux travées conformes à un premier mode de réalisation et disposées l'une à côté de l'autre, et La figure 2 est une vue similaire à la figure 1 d'une travée conforme au second mode de réalisation. FIG. 1 is a sectional view of two spans according to a first embodiment and arranged next to each other, and FIG. 2 is a view similar to FIG. 1 of a span according to the second embodiment. of realization.
Dans les exemples illustrés aux figures 1 et 2, deux voies ferrées pour du matériel roulant 1 (qui, dans les présents modes de réalisation, se déplace sur des roues garnies de pneumatique 2) sont délimitées par un assemblage de plusieurs travées 3 disposées le long les unes des autres. In the examples illustrated in FIGS. 1 and 2, two railroad tracks for rolling stock 1 (which, in the present embodiments, move on wheels lined with tire 2) are delimited by an assembly of several bays 3 arranged along each other.
Chaque travée 3 comporte une structure 4,5 qui définit une portion de la trajectoire de la voie ferrée. Each bay 3 has a structure 4,5 which defines a portion of the trajectory of the railway.
La structure 4,5 est en forme de U et comprend une dalle porteuse 6 sensiblement horizontale supportant la voie ferrée correspondante, et deux parois latérales 7 sensiblement verticales encadrant latéralement la voie ferrée. Dans les présents modes de réalisation, la structure en U 4, 5 est une structure préfabriquée, en une seule pièce, réalisée en béton armé. The structure 4,5 is U-shaped and comprises a substantially horizontal carrier slab 6 supporting the corresponding railway track, and two substantially vertical side walls 7 laterally flanking the railway track. In the present embodiments, the U-shaped structure 4, 5 is a prefabricated, one-piece structure made of reinforced concrete.
Chaque travée 3 comprend également au moins un rail latéral 8,9,10 disposé latéralement à la voie ferrée correspondante, à l'intérieur de l'espace délimité par le U formé par la structure en U 4,5. Each bay 3 also comprises at least one side rail 8, 9, 10 disposed laterally to the corresponding railway, inside the space defined by the U formed by the U-shaped structure.
Dans les présents modes de réalisation, la travée 3 comprend un rail latéral d'arrivée de courrant électrique 8 et un rail latéral de retour du courrant 9, ces deux rails latéraux 8,9 permettant l'alimentation électrique du matériel roulant 1 qui comporte des patins de contact 20,21 adaptés à frotter ces rails 8,9 de façon à établir la connexion électrique. De plus, dans les présents modes de réalisation, le matériel roulant 1 étant sur pneumatique 2, la travée 3 comprend également un rail latéral de guidage 10, la matériel roulant comportant des roues de guidage 22 dont l'axe de rotation est vertical et qui roulent contre ce rail 10 afin d'assurer le guidage transversal du matériel roulant 1. Ainsi, dans le présent mode de réalisation, à une voie ferrée est associé un ensemble de trois rails latéraux 8,9,10. Comme on peut le voir aux figures 1 et 2, les rails latéraux 8,9,10 sont portés directement par les parois latérales 7 de la structure en U 4,5. In the present embodiments, the span 3 comprises an electrical current arrival rail 8 and a lateral return rail of the current 9, these two lateral rails 8, 9 allowing the power supply of the rolling stock 1 which comprises contact pads 20,21 adapted to rub these rails 8,9 so as to establish the electrical connection. In addition, in the present embodiments, the rolling stock 1 being on the tire 2, the span 3 also comprises a lateral guide rail 10, the rolling stock comprising guide wheels 22 whose axis of rotation is vertical and which are rolled against this rail 10 to ensure the transverse guidance of the rolling stock 1. Thus, in the present embodiment, a railway is associated with a set of three side rails 8,9,10. As can be seen in Figures 1 and 2, the side rails 8,9,10 are carried directly by the side walls 7 of the U-shaped structure 4,5.
La structure en U 4,5 est dimensionnée en conséquence de sorte que, chaque paroi latérale 7 portant un rail latéral 8,9,10 supporte, ncn seulement les efforts verticaux générés par le matériel roulant 1, mais également les efforts transversaux que le matériel roulant 1 génère et transmet au rail latéral 8,9,10. The U-shaped structure 4,5 is dimensioned accordingly so that each lateral wall 7 carrying a lateral rail 8, 9, 10 supports, not only the vertical forces generated by the rolling stock 1, but also the transverse forces that the material 1 generates and transmits to the side rail 8,9,10.
Dans les présents modes de réalisation, la structure en U 4,5 est dimensionnée de sorte que chaque paroi latérale 7 supporte les efforts transversaux dus, d'une part, aux frottements des patins de contact 20,21 sur les rails d'alimentation électrique 8,9, et, d'autre part, des poussées transversales exercées par les roues de guidage 22 sur le rail du guidage 10, notamment dans les portions courbes de la voie ferrée. Des organes de fixation 11 classiques permettent la fixation de ces rails 8,9, 10 aux parois 7. In the present embodiments, the U-shaped structure 4,5 is dimensioned so that each side wall 7 supports the transverse forces due, on the one hand, to the friction of the contact pads 20, 21 on the electrical supply rails 8,9, and, secondly, transverse thrusts exerted by the guide wheels 22 on the rail of the guide 10, in particular in the curved portions of the railway. Conventional fasteners 11 allow the fastening of these rails 8, 9, 10 to the walls 7.
Par ailleurs, dans les présents modes de réalisation, les parois latérales 7 sont conformées de sorte que leur extrémité supérieure 12 atteigne sensiblement le niveau du plancher du matériel roulant 1 de façon à former, par exemple, le bord d'un quai d'une station. De plus, l'extrémité supérieure 12 s'étend transversalement légèrement vers l'intérieur du U de la structure en U 4,5 de façon à s'approcher au mieux des marchepieds du matériel roulant 1. Furthermore, in the present embodiments, the side walls 7 are shaped so that their upper end 12 substantially reaches the level of the floor of the rolling stock 1 so as to form, for example, the edge of a quay of a station. In addition, the upper end 12 extends transversely slightly towards the inside of the U of the U-shaped structure 4, so as to get as close as possible to the steps of the rolling stock 1.
Dans le premier mode de réalisation illustré à la figure 1, chaque structure en U 4 est associée à une seule voie ferrée, et deux structures en U 4 identiques sont disposées l'une à côté de l'autre, un quai central d'accès au matériel roulant 1 circulant sur les deux voies ferrées étant réalisé par la jonction des extrémités supérieures 12 des deux parois latérales 7 adjacentes de chaque structure en U 4. Aux portions de voie illustrées à la figure 1, l'ensemble des trois rails latéraux 8,9,10 associés à chaque voie ferrée est présent de chaque côté de chaque voie. De ce fait, chaque paroi latéral 7 de chaque structure en U 4 porte l'ensemble des rails latéraux 8,9,10 associés à la voie ferrée correspondante. In the first embodiment illustrated in FIG. 1, each U-shaped structure 4 is associated with a single railway line, and two identical U-shaped structures 4 are arranged one beside the other, a central access platform. rolling stock 1 traveling on the two railroad tracks being formed by the junction of the upper ends 12 of the two adjacent side walls 7 of each U-shaped structure 4. To the track portions illustrated in Figure 1, the set of three side rails 8 , 9.10 associated with each railroad is present on each side of each lane. Therefore, each side wall 7 of each U-shaped structure 4 carries all of the side rails 8,9,10 associated with the corresponding railway.
Dans le second mode de réalisation illustré à la figure 2, une seule structure en U 5 est associée à deux voies ferrées adjacentes l'une à l'autre. Aux portions de voie illustrées à la figure 2, l'ensemble des trois rails latéraux 8,9,10 associés à chaque voie ferrée est présent de chaque côté de chaque voie. De ce fait chaque paroi latérale 7 de la structure en U 5 porte l'ensemble des rails latéraux 8,9,10 associés au côte extérieur de la voie ferrée correspondante, et un support central 13, fixé à la dalle porteuse 6, entre les deux voies ferrées, porte l'ensemble des rails latéraux 8,9,10 associés au côté intérieur des deux voies ferrées. In the second embodiment illustrated in FIG. 2, a single U-shaped structure 5 is associated with two railroad tracks adjacent to one another. To the portions of the lanes illustrated in FIG. 2, all of the three lateral rails 8, 9, 10 associated with each railroad track are present on each side of each lane. As a result, each side wall 7 of the U-shaped structure 5 carries the set of side rails 8, 9, 10 associated with the outer side of the corresponding railway line, and a central support 13, fixed to the load-bearing slab 6, between the two railroad tracks, carries the set of side rails 8,9,10 associated with the inner side of the two railroad tracks.
Selon les portions de voie, il n'est pas nécessaire que l'ensemble des rails latéraux 8,9,10 associés à une voie ferrée soit présent de chaque côté de celle-ci. Depending on the portion of the track, it is not necessary for the set of side rails 8, 9, 10 associated with a railway line to be present on each side thereof.
De nombreuses modifications peuvent être apportées aux modes de réalisation de la présente invention. Many modifications can be made to the embodiments of the present invention.
Il serait possible que la structure en U soit réalisée en béton précontraint. Il serait également possible que la structure en U, notamment quand elle est en béton, ne soit pas préfabriquée mais réalisée sur site, par exemple par coffrage. La structure en U pourrait également être en métal ou partiellement en béton et partiellement en métal. La structure en U pourrait être en trois parties (la dalle et les deux parois latérales) assemblées les unes aux autres, et non pas monobloc. It is possible that the U-shaped structure is made of prestressed concrete. It would also be possible for the U-shaped structure, particularly when it is made of concrete, to be not prefabricated but made on site, for example by formwork. The U-shaped structure could also be metal or partially concrete and partly metal. The U-shaped structure could be in three parts (the slab and the two side walls) assembled to each other, and not monobloc.
Il serait aussi possible qu'à chaque voie ferrée ne soit associé qu'un seul rail latéral (soit le rail latéral d'arrivée de courrant, soit le rail de retour de courrant, soit le rail latéral de guidage) ou deux rails latéraux, selon le matériel roulant. utilisé (sur pneumatique, sur rail, alimenté par rail ou par caténaire...). De plus, il est serait également possible que, quand il y a plusieurs rails latéraux associés à une voie (deux ou trois rails), l'ensemble des rails latéraux associés ne soient pas tous disposés du même côté de la voie ferrée (un rail latéral de chaque côté quand il y a deux rails latéraux associés à la voie, ou deux rails latéraux d'un côté et le troisième rail latéral de l'autre côté quand il y en a trois d'associés). It would also be possible for each railway to be associated with only one lateral rail (either the lateral rail of current arrival, the current return rail, or the lateral guiding rail) or two lateral rails, according to the rolling stock. used (on pneumatic, on rail, fed by rail or by catenary ...). In addition, it is also possible that, when there are several side rails associated with a track (two or three rails), not all of the associated side rails are located on the same side of the track (a rail lateral on each side when there are two side rails associated with the track, or two side rails on one side and the third side rail on the other side when there are three of them).
Il serait ainsi possible que les rails latéraux portés par une paroi latérale de la structure en U soient espacés de cette paroi par une entretoise adaptée à compenser la distance séparant transversalement cette paroi latérale à la voie ferrée. En effet, notamment dans les virages, il est nécessaire d'écarter les parois latérales de la trajectoire du matériel roulant qui, lui, doit continuer à être en contact avec les rails latéraux afin d'être alimenté électriquement et d'être guidé. It would thus be possible for the side rails carried by a side wall of the U-shaped structure to be spaced from this wall by a spacer adapted to compensate for the distance transversely separating this lateral wall from the railroad track. Indeed, especially in turns, it is necessary to separate the side walls of the path of the rolling stock, which he must continue to be in contact with the side rails to be electrically powered and to be guided.
