Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention se rapporte d'une façon générale aux supports de rails de voies ferrées destinées à la circulation de véhicules, notamment des trains, des métros ou des tramways. L'invention concerne plus précisément un support de béton pour constituer un module de système de voie sur dalle et un tel système modulaire de voie sur dalle.The present invention relates generally to railway track supports for the circulation of vehicles, including trains, subways or trams. The invention relates more specifically to a concrete support for constituting a slab track system module and such a modular slab track system.

Les supports de rails pour voie ferrée sont des pièces sur lesquelles sont fixés les rails afin de fournir à ceux-ci un support adapté aux contraintes auxquelles ils sont soumis et à maintenir leur écartement tout en répartissant les charges sur l'assise de ces supports de rails, par exemple du ballast ou une dalle en béton. Ces supports peuvent être des traverses ou encore des supports pour appareil de voie au niveau des aiguillages.The railway track supports are parts on which the rails are fixed in order to provide them with a support adapted to the stresses to which they are subjected and to maintain their spacing while distributing the loads on the seat of these supports. rails, for example ballast or a concrete slab. These supports may be sleepers or supports for switchgear at the points.

Les supports de rails peuvent prendre la forme d'une traverse monobloc en béton comportant deux emplacements destinés à recevoir des rails, ou d'une traverse bi-bloc qui comprend deux blocs de béton comportant chacun un emplacement destiné à recevoir un rail et reliés par une entretoise généralement métallique.The rail supports may take the form of a concrete monobloc cross member having two locations for receiving rails, or a bi-block crossbar which comprises two concrete blocks each having a location for receiving a rail and connected by a generally metallic spacer.

Classiquement, les traverses reposent sur du ballast qui assure la transmission et la répartition des charges vers la structure d'assise supportant le ballast. Une telle configuration nécessite cependant un entretien important qui peut se révéler compliqué et coûteux, notamment dans des zones denses, avec une circulation fréquente ou à grande vitesse.Conventionally, the sleepers are based on ballast which ensures the transmission and distribution of loads to the seat structure supporting the ballast. Such a configuration, however, requires significant maintenance that can be complicated and expensive, especially in dense areas, with frequent traffic or at high speed.

Les traverses en béton, par leur poids important assurent un bon ancrage de la voie, et leur solidité et résistance facilite la maintenance. Cependant, deux traverses consécutives ne sont pas soumises exactement aux mêmes contraintes, et ne sont reliées entre elles que par le rail qu'elles supportent, de sorte que le support du rail peut ne pas être homogène, ce qui peut poser problème notamment lors du vieillissement de la voie, nécessitant un entretien plus coûteux.Because of their high weight, the concrete sleepers ensure a good anchoring of the track, and their strength and resistance make maintenance easier. However, two consecutive crosspieces are not subjected to exactly the same constraints, and are interconnected only by the rail they support, so that the support of the rail may not be homogeneous, which can be problematic especially during the aging of the track, requiring more expensive maintenance.

Des systèmes de voie sur dalle ont été développés, qui rassemblent en un seul tenant plusieurs emplacements de fixation d'un même rail. Par exemple, la demande de brevet GB 2 477 319 A décrit un système de dalles pour accueillir des rails, chaque dalle étant munie d'un conduit s'étendant depuis la surface de la dalle, jusqu'à une de ses extrémités, pour accueillir un élément de liaison joignant deux dalles adjacentes.Slab track systems have been developed that unite a number of mounting locations of a single rail. For example, the patent application GB 2,477,319 A discloses a slab system for accommodating rails, each slab having a conduit extending from the slab surface to one end thereof for accommodating a connecting member joining two adjacent slabs.

De tels systèmes font typiquement plusieurs mètres de longueur (dans le sens du rail). Ces systèmes de voie sur dalle permettent notamment de diminuer les coûts de maintenance, d'augmenter la sécurité et le confort des passagers en raison de la régularité et de la fiabilité qu'ils apportent quant au maintien des rails.Such systems are typically several meters in length (in the rail direction). In particular, these slab track systems make it possible to reduce maintenance costs and increase passenger safety and comfort because of the regularity and reliability they provide in maintaining the rails.

Cependant, ces systèmes de voie sur dalle sont composés d'éléments de grande dimension ; ils sont très lourds, et leur implantation sur leur assise devient complexe, tant à cause de leur poids que de leur encombrement. Ils nécessitent en outre une assise dont la régularité des dimensions doit être finement maîtrisée. Par ailleurs, la géométrie de la voie est obtenue par des tolérances très serrées en fabrication, voire des reprises en usinage, ou bien encore en utilisant entre le rail et la dalle des systèmes de selles réglables. L'obtention de la géométrie de la voie s'avère alors complexe et coûteuse. En outre, le vieillissement de la voie peut altérer cette géométrie.However, these slab track systems are composed of large elements; they are very heavy, and their implantation on their base becomes complex, because of their weight and their size. They also require a seat whose regularity of dimensions must be finely controlled. Moreover, the geometry of the track is obtained by very tight tolerances in manufacture, even times in machining, or even using between the rail and the slab adjustable saddle systems. Obtaining the geometry of the path then proves to be complex and expensive. In addition, the aging of the track can alter this geometry.

The invention will be better understood, thanks to the following description, which relates to embodiments and variants according to the present invention, given by way of non-limiting examples and explained with reference to the attached schematic drawings, in which:

La figure 1 représente une vue en perspective d'un support de voie 2 selon la présente invention, qui est en béton et comprend au moins un emplacement de fixation 3 de rail ménagé sur une première face dite supérieure 4 dudit support 2, deux faces latérales opposées 5 adjacentes à ladite face supérieure 4, généralement sensiblement perpendiculaires à celle-ci et à la direction de la voie qu'est destinée à définir le support 2. Chacune des faces latérales 5 du support de voie 2 comprend au moins un orifice de réception 6 adapté pour recevoir un élément de liaison 9 apte à relier rigidement ledit support de voie 2 avec un autre support de voie dans la direction de la voie. Pour des raisons de lisibilité, un seul élément de liaison 9 est représenté.The figure 1 represents a perspective view of a track support 2 according to the present invention, which is made of concrete and comprises at least one rail attachment location 3 formed on a first so-called upper face 4 of said support 2, two opposite side faces 5 adjacent to said upper face 4, generally substantially perpendicular thereto and to the direction of the track intended to define the support 2. Each of the lateral faces 5 of the track support 2 comprises at least one receiving orifice 6 adapted to receiving a connecting element 9 adapted to rigidly connect said track support 2 with another track support in the direction of the track. For reasons of readability, only one connecting element 9 is shown.

Dans l'exemple illustré en figure 1, ce support de voie 2 comprend deux emplacements de fixation 3 de rail positionnés sur la face supérieure 4 du support de voie 2 selon une direction principale différente de la direction de la voie. Ces emplacements de fixation 3 de rail comprennent une partie centrale formant un creux destinée à recevoir le rail, et deux parties latérales dont l'épaisseur est supérieure à celle de la partie centrale de sorte qu'elles forment des rebords de part et d'autre de la partie centrale recevant le rail, afin de permettre de maintenir l'écartement des rails et leur fixation.In the example shown in figure 1 , this track support 2 comprises two rail attachment locations 3 positioned on the upper face 4 of the track support 2 in a main direction different from the direction of the track. These rail attachment locations 3 comprise a central part forming a recess intended to receive the rail, and two lateral parts whose thickness is greater than that of the central part so that they form flanges on both sides. the central part receiving the rail, to allow to maintain the spacing of the rails and their attachment.

De plus comme illustré en figure 1, au moins une des faces latérales opposées 5 comprend une pluralité d'orifices de réception 6. Ces orifices peuvent être de dimensions différentes selon la taille et le type d'élément de liaison 9 destiné à être inséré dedans pour relier rigidement ensemble un premier support de voie 2 avec au moins un autre support de voie similaire.Also as illustrated in figure 1 at least one of the opposite lateral faces 5 comprises a plurality of receiving orifices 6. These orifices may be of different dimensions depending on the size and the type of connecting element 9 intended to be inserted in to rigidly connect together a first support track 2 with at least one other similar track support.

Par exemple, pour un même support de voie, des orifices de réception d'une certaine dimension peuvent être destinés à recevoir des barres en acier, tandis que d'autres orifices de réception 6 peuvent être destinés à recevoir des inserts de type voussoir.For example, for the same track support, receiving orifices of a certain size may be intended to receive steel bars, while other receiving orifices 6 may be intended to receive inserts of the voussoir type.

Les barres en acier sont rigides et droites, et sont destinées à être insérées dans des orifices de réception 6 débouchant traversant le support de voie dans son sens longitudinal, c'est-à-dire dans la direction de la voie, depuis une face latérale 5 à celle qui lui est opposée, permettant ainsi de lier ensemble plus de deux supports de voie. Un mortier de scellement est ensuite injecté dans l'espace libre entre la barre d'acier et l'orifice de réception débouchant 6 afin de rigidifier la liaison.The steel bars are rigid and straight, and are intended to be inserted into receiving openings 6 opening through the track support in its longitudinal direction, that is to say in the direction of the track, from a side face 5 to that which is opposed to it, thus allowing to bind together more than two supports of way. A sealing mortar is then injected into the free space between the steel bar and the opening opening 6 to stiffen the connection.

Les inserts de type voussoir présentent une forme arrondie dans le sens de leur insertion et sont destinés à être insérés dans des orifices de réception 6 borgnes, s'étendant dans la direction de la voie. Les orifices de réception 6 peuvent être formés par des inserts en matière plastique intégré à la dalle lors de sa fabrication. La liaison rigide entre les éléments de dalle est obtenue dès insertion des éléments de liaison 9 dans les orifices de réception 6 sans qu'il y ait besoin de nouvelles opérations type coulage de mortier ou autre.The voussoir type inserts have a rounded shape in the direction of their insertion and are intended to be inserted into blind receiving ports 6, extending in the direction of the track. The receiving orifices 6 may be formed by plastic inserts integrated into the slab during its manufacture. The rigid connection between the slab elements is obtained as soon as the connecting elements 9 are inserted into the receiving orifices 6 without the need for new operations such as pouring mortar or the like.

L'avantage de l'utilisation d'élément de liaison 9 de type voussoir est que ce type de liaison ne nécessite pas d'intervention ultérieure: une fois les supports de voie brochés, ils sont solidaires et forment un système de voie sur dalle.The advantage of the use of link element 9 type voussoir is that this type of connection does not require further intervention: once the track media are stitched, they are integral and form a slab track system.

Comme indiqué plus haut, ces orifices de réception 6 peuvent être borgnes ou traversant, selon le type d'élément de liaison 9 destinés à être insérés et le type d'assemblage souhaité. En effet, si on veut assembler plusieurs supports de voie 2 pour former un système de voie sur dalle 1, avec au moins un même élément de liaison 9, l'orifice de réception 6 est traversant pour au moins les supports de voie 2 se situant entre les supports de voie 2 formant extrémités dudit système de voie sur dalle 1.As indicated above, these receiving orifices 6 can be blind or through, depending on the type of connecting element 9 to be inserted and the type of assembly desired. Indeed, if one wants to assemble several track supports 2 to form a slab track system 1, with at least one connecting element 9, the receiving orifice 6 is traversing for at least the track supports 2 located between the track supports 2 forming ends of said slab track system 1.

Comme notamment représenté en figure 1, l'orifice de réception 6, adapté pour recevoir un élément de liaison 9, peut être ménagé en regard d'un emplacement de fixation 3 de rail. Plus précisément, l'orifice de réception 6 s'étend dans une direction parallèle à celle de la voie, c'est-à-dire dans la direction des rails, à l'intérieur du support de voie 2. L'orifice de réception 6 s'étend de façon rectiligne dans un plan parallèle à la face inférieure du support de voie 2.As particularly represented in figure 1 , the receiving orifice 6, adapted to receive a connecting element 9, may be arranged opposite a rail attachment location 3. More specifically, the receiving orifice 6 extends in a direction parallel to that of the track, that is to say in the direction of the rails, inside the track support 2. The receiving orifice 6 extends rectilinearly in a plane parallel to the underside of the track support 2.

Afin de faciliter le positionnement du support de voie 2 sur une assise quelconque qui peut être de tout type, comme par exemple du ballast, de la grave bitume, du béton ou tout autre médium, le support de voie 2 comprend au moins un trou de réglage traversant 7 adapté pour recevoir un élément de réglage 10 de positionnement dudit support 2, ménagé sur la face supérieure 4 dudit support 2, comme illustré aux figures 1, 2.In order to facilitate the positioning of the track support 2 on any seat which may be of any type, such as for example ballast, heavy bitumen, concrete or any other medium, the track support 2 comprises at least one hole of through adjustment 7 adapted to receive a setting element 10 for positioning said support 2, provided on the upper face 4 of said support 2, as illustrated in FIGS. Figures 1, 2 .

Préférentiellement, le support de voie 2 comprend deux trous de réglage traversants 7 ménagés sur la face supérieure 4 dudit support 2, et au moins un emplacement de fixation 3 de rail est disposé entre lesdits deux trous de réglage traversants 7. Dans les exemples illustrés aux figures 1 et 2, les deux trous de réglage traversants 7 sont disposés chacun à une extrémité du support de voie 2, séparés par deux emplacements de fixation 3, afin de permettre un réglage de positionnement du support de voie plus facile et précis par rapport à l'assise sur laquelle il est destiné à être installé.Preferably, the track support 2 comprises two through-adjusting holes 7 formed on the upper face 4 of said support 2, and at least one rail attachment location 3 is disposed between said two through-throttling holes 7. In the examples illustrated in FIGS. Figures 1 and 2 , the two through-adjusting holes 7 are each arranged at one end of the track support 2, separated by two fixing locations 3, in order to allow a positioning adjustment of the track support easier and more precise with respect to the seat on which it is intended to be installed.

Avantageusement, selon la présente invention et comme représenté aux figures 1 et 2, le support de voie 2 comprend au moins un trou d'injection 14 de produit de calage.Advantageously, according to the present invention and as represented in Figures 1 and 2 , the track support 2 comprises at least one injection hole 14 of setting product.

Ce trou d'injection 14 de produit de calage est traversant, débouchant sur la face supérieure 4 du support de voie 2, et permet de faciliter l'injection du coulis de calage. Ce trou d'injection 14 peut également avantageusement servir au scellement de tige de d'ancrage insérée à l'intérieur de ces derniers pour la reprise des efforts latéraux, comme représenté sur la figure 8. Le support de voie peut également comprendre au moins un trou d'évent traversant destiné à l'évacuation de l'air lors de l'injection du produit de calage.This injection hole 14 of wedging product is through, opening on the upper face 4 of the track support 2, and facilitates the injection of the setting grout. This injection hole 14 may also advantageously serve for anchoring rod sealing inserted inside these for the recovery of lateral forces, as shown in FIG. figure 8 . The track support may also comprise at least one through-vent hole intended for evacuation of the air during the injection of the cushioning product.

Dans une configuration de traverses monoblocs, chaque support de voie 2 peut être positionné et réglé séparément, et les supports de voie sont ensuite reliés entre eux pour former un système de voie sur dalle modulaire 1.In a one-piece tie configuration, each track support 2 can be positioned and adjusted separately, and the track supports are then interconnected to form a modular slab track system 1.

Dans une configuration de traverses bi-blocs, chaque support de voie 2 est relié à au moins un autre support de voie 2 dans une direction destinée à être perpendiculaire à la voie pour former un ensemble de supports de voie, les ensembles ainsi obtenus étant ensuite positionnés selon une répartition dans la direction de la voie, réglés séparément et ensuite reliés entre eux pour former le système de voie sur dalle modulaire 1.In a configuration of two-block crosspieces, each track support 2 is connected to at least one other track support 2 in a direction intended to be perpendicular to the track to form a set of track supports, the assemblies thus obtained being then positioned in a lane directional distribution, separately adjusted and then interconnected to form the Modular Slab Track System 1.

Il est également possible de reliés entre eux des modules adjacents constitués par les supports de voie 2 ou par les ensembles de supports de voie, pour former un système de voie sur dalle modulaire 1, puis de les régler. C'est notamment le cas lorsque les éléments de liaisons 9 ne traversent pas un support de voie 2, ce qui est le cas par exemple des supports de voie de type voussoir.It is also possible to connect adjacent modules consisting of the track supports 2 or the sets of track supports together to form a modular slab track system 1 and then adjust them. This is particularly the case when the connecting elements 9 do not pass through a track support 2, which is the case, for example, of track-type track supports.

Les figures 3 et 4 montrent le réglage lors de la mise en place d'un support de voie 2 similaire à celui de la figure 1. Le support de voie 2 est disposé sur une assise 13, puis des tiges de réglage 10 sont introduites dans les trous de réglages 7 (figure 3). Les tiges de réglages 10 sont filetées et les trous de réglages 7 présentent un taraudage, par exemple au moyen d'un insert ou d'une gaine plastique rapporté dans le trou de réglage 7. Les tiges de réglages 10 sont alors vissées dans les trous de réglages 7 afin que leur coopération avec l'assise 13 écarte le support de voie 2 de l'assise 13, de sorte à créer un espace libre pour l'injection du produit de calage. L'indépendance entre elles des tiges de réglages permet d'ajuster l'inclinaison du support de voie 2 par rapport à l'assise 13.The Figures 3 and 4 show the setting when setting up a track support 2 similar to that of the figure 1 . The track support 2 is placed on a seat 13, then adjustment rods 10 are introduced into the adjustment holes 7 ( figure 3 ). The adjustment rods 10 are threaded and the setting holes 7 have a tapping, for example by means of an insert or a plastic sheath reported in the adjustment hole 7. The adjustment rods 10 are then screwed into the holes of settings 7 so that their cooperation with the seat 13 spreads the track support 2 of the seat 13, so as to create a free space for the injection of the cushioning product. The independence between them of the adjustment rods makes it possible to adjust the inclination of the track support 2 with respect to the seat 13.

Comme on peut le voir sur les figures 1 à 9, le support de voie 2 peut comprendre une couche résiliente 8 sur sa face inférieure. Cette couche résiliente 8 peut recouvrir la face inférieure du support de voie 2 et permet d'ajuster la raideur de voie, d'améliorer la distribution des charges, de participer à l'atténuation des vibrations et de permettre la circulation sur les dalles avant coulage du produit de calage pour des trains travaux par exemple. Dans l'exemple illustré en figure 8, la couche résiliente peut aussi au moins partiellement revêtir les parois du trou d'injection 14 ainsi que les faces latérales du support 2.As can be seen on the Figures 1 to 9 the track support 2 may comprise a resilient layer 8 on its underside. This resilient layer 8 can cover the lower face of the track support 2 and makes it possible to adjust the stiffness of the track, to improve the distribution of the loads, to participate in the attenuation of the vibrations and to allow the circulation on the slabs before casting. of the product for work trains for example. In the example shown in figure 8 the resilient layer may also at least partially coat the walls of the injection hole 14 as well as the side faces of the support 2.

Selon des variantes non représentées des modes de réalisation du support de voie 2 représentés aux figures 1 à 7, le support de voie 2 n'est pas nécessairement muni d'une couche résiliente 8. En effet, le support de voie 2 peut être en contact direct avec le produit de calage 11, la couche résiliente 8 étant optionnelle.According to non-represented variants of the embodiments of the track support 2 represented in FIGS. Figures 1 to 7 the track support 2 is not necessarily provided with a resilient layer 8. Indeed, the track support 2 may be in direct contact with the wedging product 11, the resilient layer 8 being optional.

Selon une caractéristique de l'invention, la face supérieure 4 du support de voie 2 peut présenter une pente pour permettre le drainage des eaux. A cet effet, au moins une partie de la face supérieure 4 n'est pas parallèle à la face inférieure qui lui est opposée. La face supérieure 4 peut présenter des moyens de maîtrise de l'évacuation des eaux de ruissellement, tels que des caniveaux, drains, etc.According to a feature of the invention, the upper face 4 of the track support 2 may have a slope to allow drainage of water. For this purpose, at least a portion of the upper face 4 is not parallel to the opposite face opposite to it. The upper face 4 may have means for controlling the discharge of runoff water, such as gutters, drains, etc.

Selon une autre caractéristique de l'invention, le support de voie 2 peut comprendre des inserts ou réservations pour permettre la fixation par exemple de balises et/ou de rails de sécurité et/ou de chemin de câbles écrans antibruit.According to another characteristic of the invention, the track support 2 may comprise inserts or reservations to allow the attachment for example of beacons and / or safety rails and / or noise barrier wireway.

De plus, selon une autre caractéristique de l'invention, la face supérieure 4 du support de voie 2 peut être revêtue d'un matériau absorbant phonique comme par exemple du béton de bois ou de pouzzolane.In addition, according to another characteristic of the invention, the upper face 4 of the track support 2 may be coated with a sound absorbing material such as wood or pozzolan concrete.

Par ailleurs, selon une autre caractéristique de l'invention, la face supérieure 4 du support de voie 2 peut être revêtue d'un matériau antidérapant ou bien traitée pour augmenter sa rugositéFurthermore, according to another characteristic of the invention, the upper face 4 of the track support 2 may be coated with a non-slip material or treated to increase its roughness.

La présente invention a également pour objet un ensemble de support de voie comprenant deux supports de voie 2 reliés entre eux par une entretoise dans une direction destinée à être perpendiculaire à la voie. L'ensemble de support de voie correspond à par exemple une traverse dite bi-bloc comme expliqué plus haut dans la description. Les supports de voie 2 de l'ensemble sont réalisés en béton et sont reliés par une entretoise de préférence métallique.The present invention also relates to a track support assembly comprising two track supports 2 interconnected by a spacer in a direction intended to be perpendicular to the track. The track support assembly corresponds to for example a cross said bi-block as explained above in the description. The track supports 2 of the assembly are made of concrete and are connected by a spacer preferably of metal.

Dans ce cas, chacun des supports de voie 2 de l'ensemble peut alors prendre la forme d'une moitié du support illustré en figure 1, et il peut notamment en reprendre la plupart des caractéristiques qui sont expliquées aux paragraphes précédents.In this case, each of the track supports 2 of the assembly can then take the form of a half of the support illustrated in FIG. figure 1 , and it can include most of the features that are explained in the previous paragraphs.

Comme illustré à la figure 2 et à la figure 10, la présente invention concerne également un système de voie sur dalle 1 modulaire et comprenant une série de modules, chaque module comprenant un support de voie 2 ou un ensemble de deux supports de voie 2 reliés entre eux dans une direction destinée à être perpendiculaire à la voie, tel que décrit plus haut. Chaque module est relié rigidement à un autre module similaire par au moins un élément de liaison 9 inséré dans des orifices de réception 6 respectifs desdits modules dans la direction de la voie.As illustrated in figure 2 and at the figure 10 the present invention also relates to a modular slab track system 1 comprising a series of modules, each module comprising a track support 2 or a set of two track supports 2 interconnected in a direction intended to be perpendicular to the track. route, as described above. Each module is rigidly connected to another similar module by at least one connecting element 9 inserted into respective receiving orifices 6 of said modules in the direction of the track.

On entend par système modulaire, un système dont chacun des modules est indépendant et dont l'assemblage entre eux peut se réaliser avant ou après fixation sur assise desdits modules et dont chaque module est interchangeable ou remplaçable indépendamment les uns des autres.Modular system means a system of which each of the modules is independent and whose assembly between them can be achieved before or after fixing on the seat of said modules and each module is interchangeable or replaceable independently of each other.

Plus précisément, si un des modules est endommagé, on peut le remplacer par un autre module sans remplacer l'ensemble du système, sauf éventuellement les éléments de liaison reliant ce module aux autres. En effet, le remplacement d'un module peut être réalisé par exemple en sectionnant la liaison entre les supports de voie 2. Un système de fixation extérieure est alors positionné si nécessaire. Le faible poids et encombrement des supports de voie 2 permet d'effectuer les travaux de remplacement simplement et dans un délai limité.More precisely, if one of the modules is damaged, it can be replaced by another module without replacing the entire system, except possibly the connecting elements connecting this module to others. Indeed, the replacement of a module can be achieved for example by cutting the connection between the track supports 2. An external fixing system is then positioned if necessary. The low weight and size of the track supports 2 makes it possible to carry out replacement work simply and within a limited time.

Comme représenté à la figure 2 et à la figure 10, l'orifice de réception 6 de chaque module peut être traversant et au moins trois modules constituant la voie sur dalle 1 sont reliés par au moins un même élément de liaison 9 traversant un orifice de réception 6 respectif de chaque module.As represented in figure 2 and at the figure 10 , the receiving orifice 6 of each module may be through and at least three modules constituting the slab channel 1 are connected by at least one connecting element 9 passing through a respective receiving orifice 6 of each module.

Le système de voie sur dalle 1 peut comprendre une série de modules reliés deux-à-deux par une pluralité d'éléments de liaison 9, chaque module étant relié à un autre module par au moins un élément de liaison 9 reçu dans un orifice de réception 6 borgne de chaque module.The slab track system 1 may comprise a series of modules connected in pairs by a plurality of connecting elements 9, each module being connected to another module by at least one connecting element 9 received in a port of FIG. 6 blind reception of each module.

Bien entendu, comme chacun des supports de voie 2 peut comprendre une pluralité d'orifices de réception 6, le système de voie sur dalle modulaire 1 peut accueillir plusieurs éléments de liaison 9 entre chaque module. Il est donc possible combiner des solutions de liaison par des éléments de liaison reçus par des orifices de réception 6 traversants et/ou des orifices de réception 6 borgnes.Of course, as each of the track supports 2 may comprise a plurality of receiving orifices 6, the modular slab track system 1 can accommodate a plurality of connecting elements 9 between each module. It is therefore possible to combine connection solutions by connecting elements received by receiving orifices 6 through and / or blind receiving ports 6.

Le système de voie sur dalle 1 selon la présente invention est conçu avantageusement pour être compatible avec n'importe quel système d'attache de rails connu.The slab track system 1 according to the present invention is advantageously designed to be compatible with any known rail fastening system.

Par ailleurs, le système de voie sur dalle 1 selon la présente invention autorise l'utilisation de système d'attache de rail réglable permettant la reprise de la géométrie de voie en cas de tassement léger de l'assise 13.Furthermore, the slab track system 1 according to the present invention allows the use of an adjustable rail fastening system allowing the recovery of the track geometry in case of slight settlement of the seat 13.

On propose également un procédé de mise en place d'un système de voie sur dalle modulaire 1 sur une assise 13 comprenant une étape d'assemblage de deux modules comprenant chacun au moins un supports de voie 2 ou un ensemble de deux supports de voie selon la présente invention, dans laquelle les faces latérales 5 pourvues d'au moins un orifice de réception 6 desdits au moins deux supports de voie 2 sont positionnées en regard l'une de l'autre, et au moins un élément de liaison 9 est inséré dans un orifice de réception 6 d'un support de voie 2 adapté pour recevoir ledit élément de liaison 9, puis les supports de voie 2 sont rapprochés afin que l'élément de liaison 9 rentre dans un orifice de réception de l'autre support de voie 2. L'assise 13 peut être en béton, en grave bitume, en ballast ou tout autre médium remplissant la fonction d'assise.There is also provided a method of setting up a modular slab track system 1 on a seat 13 comprising a step of assembling two modules each comprising at least one track support 2 or a set of two track supports according to the present invention, wherein the side faces 5 provided with at least one receiving orifice 6 of said at least two track supports 2 are positioned opposite one another, and at least one connecting element 9 is inserted in a receiving port 6 of a track support 2 adapted to receive said connecting element 9, then the track supports 2 are brought together so that the connecting element 9 enters a receiving orifice of the other support of way 2. The seat 13 may be concrete, heavy bitumen, ballast or other medium fulfilling the seating function.

Le procédé de mise en place peut comprendre une étape préliminaire à l'étape d'injection, l'étape préliminaire étant un réglage du positionnement en inclinaison et en hauteur par rapport à l'assise 13 du support de voie 2 ou de l'ensemble de supports de voie constituant un module pour la voie sur dalle, comme décrit plus haut et illustré par les figure 3 et 4.The delivery method may comprise a preliminary step in the injection step, the preliminary step being an adjustment of the positioning in inclination and in height with respect to the seat 13 of the track support 2 or of the assembly of track supports constituting a module for the slab track, as described above and illustrated by the figure 3 and 4 .

Comme illustré aux figures 5 à 9, le procédé de mise en place comprend une étape d'injection d'un produit de calage 11 entre au moins un support de voie 2 et l'assise 13. Le produit de calage est injecté via un trou d'injection 14 représenté par exemple sur les figures 1 et 4. Le produit de calage 11 est préférentiellement du mortier de ciment ou de résine.As illustrated in Figures 5 to 9 , the implementation method comprises a step of injecting a wedging product 11 between at least one track support 2 and the seat 13. The wedging product is injected via an injection hole 14 shown for example on the figures 1 and 4 . The setting product 11 is preferably cement or resin mortar.

Comme illustré sur la figure 8, une tige d'ancrage 15 peut être préalablement insérée dans le trou d'injection 14 et scellée dans l'assise 13 afin de renforcer le scellement du support de voie 2. La figure 5 représente un mode de réalisation du procédé de mise en place d'un support de voie 2 dans lequel le support de voie 2 est fixé sur l'assise par un produit de calage 11, et le produit de calage 11 est injecté entre la couche résiliente 8 et l'assise 13. La couche résiliente 8 permet d'une part d'améliorer l'adhérence du produit de calage 11 sur le support de voie 2 et d'autre part d'améliorer la distribution de charges transversales des supports de voie 2.As illustrated on the figure 8 , an anchor rod 15 may be inserted beforehand into the injection hole 14 and sealed in the seat 13 to reinforce the sealing of the track support 2. The figure 5 represents an embodiment of the method of setting up a track support 2 in which the track support 2 is fixed on the seat by a wedging product 11, and the wedging product 11 is injected between the resilient layer 8 and the seat 13. The resilient layer 8 allows on the one hand to improve the adhesion of the wedging product 11 on the track support 2 and on the other hand to improve the transverse load distribution of the track supports 2.

Dans une variante non représentée, le support de voie 2 ne comprend pas de couche résiliente 8 et le produit de calage 11 est donc injecté entre le support de voie 2 lui-même et l'assise 13.In a variant not shown, the track support 2 does not include a resilient layer 8 and the wedging product 11 is thus injected between the track support 2 itself and the seat 13.

La figure 6 représente un autre mode de réalisation du procédé de mise en place d'un support de voie 2 dans lequel le produit de calage 11 a pour fonction de fixer le support de voie 2 sur l'assise mais également il sert de buton de part et d'autre du support de voie 2 permettant un soutien mécanique supplémentaire de celui-ci.The figure 6 represents another embodiment of the method of setting up a track support 2 in which the wedging product 11 has the function of setting the track support 2 on the seat but also serves as a buttrum on both sides of the track support 2 for additional mechanical support thereof.

Comme représenté en figure 4, le support de voie 2 est revêtu d'une couche résiliente 8 intercalée entre le produit de calage 11 et le support de voie 2, cette couche remontant sensiblement sur les faces latérales opposées du support de voie 2 et étant disposée entre ces dernières et le butonage du produit de calage 11.As represented in figure 4 , the track support 2 is coated with a resilient layer 8 interposed between the wedging product 11 and the track support 2, this layer rising substantially on the opposite side faces of the track support 2 and being disposed between them and the butonage of the cushioning product 11.

Dans une variante non représentée, le support de voie 2 ne comprend pas de couche résiliente 8 et le produit de calage 11 est donc injecté entre le support de voie 2 lui-même et l'assise 13, le butonage remontant sur les faces latérales en contact direct avec le béton du support de voie 2.In a variant not shown, the track support 2 does not comprise a resilient layer 8 and the wedging product 11 is thus injected between the track support 2 itself and the seat 13, butonage going up on the lateral faces in FIG. direct contact with the concrete of the track support 2.

La figure 7 représente un autre mode de réalisation du procédé de mise en place d'un support de voie 2 dans lequel le support de voie 2 est butoné mécaniquement par des butées mécaniques 12 latérales qui sont scellées dans l'assise 13. De plus, le support de voie 2 est revêtu d'une couche résiliente 8 disposée à la fois entre le produit de calage 11 et le support de voie 2 mais également entre chaque butée mécanique 12 latérale.The figure 7 represents another embodiment of the method of setting up a track support 2 in which the track support 2 is mechanically buttressed by lateral mechanical stops 12 which are sealed in the seat 13. In addition, the support of lane 2 is coated with a resilient layer 8 disposed both between the wedging product 11 and the track support 2 but also between each lateral mechanical stop 12.

En l'absence de couche résiliente au niveau des parois latérales, les butées mécaniques 12 latérales peuvent être également scellées dans le support de voie 2 en sus d'un scellement dans l'assise 13.In the absence of a resilient layer at the side walls, the lateral mechanical stops 12 can also be sealed in the track support 2 in addition to a seal in the seat 13.

Dans une autre variante, il est possible que le support de voie 2 soit directement en contact avec les butées mécaniques 12 latérales et le produit de calage 11, une couche résiliente 8 pouvant alors être présente sur les parois latérales.In another variant, it is possible that the track support 2 is directly in contact with the lateral mechanical stops 12 and the wedging product 11, a resilient layer 8 can then be present on the side walls.

La figure 8 représente un autre mode de réalisation du procédé de mise en place d'un support de voie 2 dans lequel le support de voie comprend une couche résiliente 8 qui est disposée à la fois sur la face inférieure du support de voie mais également dans les trous d'injection 14. Par ailleurs, comme expliqué plus haut, des tiges d'ancrage 15 peuvent être introduites dans les trous d'injection 14 avant l'injection du produit de calage 11.The figure 8 represents another embodiment of the method of setting up a track support 2 in which the track support comprises a resilient layer 8 which is disposed both on the underside of the track support but also in the holes of In addition, as explained above, anchoring rods 15 can be introduced into the injection holes 14 before injection of the setting product 11.

La figure 9 représente un mode de réalisation du procédé de mise en place du système de voie sur dalle 1 sur assise 13. Dans ce mode de réalisation, un matériau de remplissage 16, par exemple du ballast, est utilisé entre deux supports de voie 2 ou entre deux ensembles de support de voie permettant d'améliorer la stabilité latérale du système de voie sur dalle 1 en bénéficiant d'un effet de poids sur le support de voie 2 ou l'ensemble de support de voie.The figure 9 represents an embodiment of the method of setting up the track system on slab 1 on seat 13. In this embodiment, a filling material 16, for example ballast, is used between two track supports 2 or between two track support assemblies for improving the lateral stability of the slab track system 1 by benefiting from a weight effect on the track support 2 or the track support assembly.

Les modes de réalisation représentés aux figures 1 à 9 et leurs variantes non représentées permettent d'améliorer la résistance latérale et longitudinale de la voie, les modes de réalisations et leur variantes étant combinables dans la mesure du possible technique et notamment le réglage de positionnement en inclinaison et en hauteur de chaque support de voie 2 peut être à chaque fois réalisé avant injection du produit de calage 11, et ce, quel que soit le mode de réalisation utilisé.The embodiments shown in Figures 1 to 9 and their variants, not shown, make it possible to improve the lateral and longitudinal resistance of the track, the embodiments and their variants being combinable as far as possible with the technique, in particular the adjustment of positioning in inclination and in height of the track. each track support 2 can be performed each time before injection of the wedging product 11, and this, whatever the embodiment used.

La figure 10 illustre en vue de dessus, un plancher pour appareil de voie comprenant un système de voie sur dalle 1 selon la présente invention. Cet appareil de voie peut comprendre des supports de voie 2 de différentes dimension et pouvant recevoir une pluralité d'emplacement de fixation 3 de rails nécessaires pour un aiguillage.
