Description

L'invention se rapporte à un support de roulage ou de guidage comprenant un rail de guidage ou de roulage ferroviaire enrobé d'une matière de gamissage, ainsi qu'à un procédé pour sa mise en place dans le sol; voir par exemple FR-A-2865986 . Le rail selon l'invention est préférentiellement réalisé et livré en tronçons droits, cintrés à la pose pour s'adapter aux courbures du trajet.The invention relates to a rolling or guiding support comprising a guiding or rail rolling rail encased in a packing material, and to a method for placing it in the ground; see for example FR-A-2865986 . The rail according to the invention is preferably made and delivered in straight sections, bent to the pose to adapt to the curvatures of the path.

Dans une application particulière, l'invention concerne un support comprenant un rail enrobé de guidage, destiné à être noyé dans le sol, à chants formant pistes de roulement pour un ensemble de guidage à galets inclinés pour un véhicule routier urbain de transport en commun.In a particular application, the invention relates to a support comprising a guide rail, intended to be embedded in the ground, with songs forming running tracks for an inclined roller guide assembly for an urban road transport public vehicle.

Certains véhicules urbains guidés de transport en commun utilisent pour leur guidage un rail de guidage dont la surface supérieure affleure avec ou dépasse légèrement le niveau du sol.Some urban public transit vehicles use a guide rail for guidance, the upper surface of which is flush with or slightly above the ground level.

Ce rail de guidage est classiquement mis en place dans une engravure creusée dans le sol et remplie de béton, dans laquelle il repose par sa semelle d'appui et dans laquelle il est maintenant par des dispositifs intermédiaires de fixation régulièrement répartis dans l'engravure.This guide rail is conventionally set up in an engravure dug in the ground and filled with concrete, in which it rests by its base plate and in which it is now by intermediary fixing devices regularly distributed in the engravure.

L'espace existant entre le béton et les flancs du rail de guidage peut ensuite être comblé par une matière de garnissage laissant cependant libres des espaces linéaires appelés gorges nécessaires au passage du mentonnet du ou des galets de guidage.The space between the concrete and the flanks of the guide rail can then be filled by a lining material leaving however free linear spaces called grooves necessary for the passage of the lug or guide rollers.

Selon une invention antérieure du déposant, cette matière de garnissage est préférentiellement une résine synthétique coulée sur place au moment de la pose du rail de guidage. Elle présente des propriétés de compressibilité lui permettant d'assurer l'évacuation, l'enfoncement ou l'incrustation des objets pouvant se trouver dans la gorge de guidage.According to an earlier invention of the applicant, this packing material is preferably a synthetic resin cast in place at the time of laying the guide rail. It has compressibility properties allowing it to evacuate, sink or incrustation of objects that may be in the guide groove.

En effet, en raison de son exposition aux intempéries et au milieu ambiant, il arrive couramment que la gorge soit localement obstruée par des objets de toute sorte, notamment par exemple des débris, des végétaux, de la glace, de la neige, des cailloux ou d'autres corps ou objets étrangers déposés par accident ou malveillance, qui peuvent constituer un obstacle pour le passage du ou des galets de guidage à mentonnet et peuvent conduire à un endommagement des galets ou représenter un risque de déraillement de l'ensemble de guidage du véhicule et plus grave du véhicule lui-même.Indeed, because of its exposure to the weather and the environment, it is common for the throat to be locally obstructed by objects of any kind, including for example debris, plants, ice, snow, pebbles or other foreign bodies or objects accidentally or maliciously deposited, which may be an obstacle to the passage of the guide roller or guides and may lead to damage to the rollers or to the risk of derailing the guide assembly of the vehicle and more serious of the vehicle itself.

Par ses propriétés adaptées de compressibilité, cette matière de garnissage permet l'éjection, l'enfoncement ou l'incrustation des objets lors du passage du ou des galets de guidage, permettant ainsi leur franchissement par les galets de guidage en toute sécurité.By its suitable compressibility properties, this packing material allows ejection, deposition or encrustation of the objects during the passage of the guide rollers or, allowing their crossing by the guide rollers safely.

Comme la gorge de guidage doit rester libre et du fait de la présence de la semelle d'appui, la couche de matière de garnissage est peu importante à ce niveau. Si elle est suffisante pour permettre l'enfoncement des objets de petite taille, les objets plus importants peuvent continuer à dépasser et gêner le guidage du véhicule.As the guide groove must remain free and because of the presence of the support base, the layer of packing material is not important at this level. If it is sufficient to allow small objects to sink, larger objects may continue to protrude and interfere with the guidance of the vehicle.

En outre, alors que ce comblement avec une matière de garnissage joue un rôle important pour le bon fonctionnement du guidage, sa réalisation s'avère délicate et pose souvent problème.In addition, while this filling with a lining material plays an important role for the proper operation of the guide, its realization is tricky and often poses a problem.

En effet, selon l'art antérieur, cette résine est réalisée et coulée sur le lieu du chantier. Sa composition n'est donc pas totalement maîtrisée et peut subir des variations liées au dosage, mais aussi aux conditions météorologiques et climatiques.Indeed, according to the prior art, this resin is produced and cast on site. Its composition is not completely controlled and can undergo variations related to dosage, but also to weather and climate conditions.

Son application par coulée le long du rail en respectant une géométrie précise, est déjà en soi une opération délicate, qui est de plus rendue problématique par son déroulement en extérieur avec des paramètres variables comme les différentes conditions météorologique du moment telles que la pluie, le froid, les fortes chaleurs et autres conditions, comme les pentes par exemple, pouvant compliquer la coulée de la matière de garnissage.Its application by casting along the rail respecting a precise geometry, is already in itself a delicate operation, which is also made problematic by its unwinding outside with variable parameters such as different weather conditions of the moment such as rain, cold, high heat and other conditions, such as slopes, may complicate the casting of the packing material.

Une telle situation peut engendrer des malfaçons dommageables, voire dangereuses pour l'exploitation des véhicules.Such a situation can give rise to damaging and even dangerous malfunctions for the operation of the vehicles.

La présente invention a pour but de fournir un support de guidage ou de roulage dont le rail de guidage ou de roulage est déjà enrobé par la matière de garnissage avant sa pose dans le sol.The present invention aims to provide a guiding or rolling support whose guide rail or rolling is already coated by the lining material before laying in the ground.

Le support de roulage ou de guidage selon l'invention comprend un rail de guidage ou de roulage et une engravure remplie d'une matière de scellement dans laquelle le rail est mis en place. Ce rail comporte une tête de forme adaptée pour le roulement d'au moins un galet de guidage ou de roulage, une base et une âme réunissant la tête et la base.The rolling or guiding support according to the invention comprises a guide or rolling rail and an engravure filled with a sealing material in which the rail is put in place. This rail comprises a shaped head adapted for rolling at least one guide roller or rolling, a base and a core joining the head and the base.

Selon l'invention, le rail de guidage ou de roulage est, avant sa pose, partiellement revêtu, sur sensiblement toute sa longueur, d'une matière de garnissage, formant un enrobage qui comprend au moins une extension latérale destinée à reposer sur la matière de scellement et dans laquelle est ménagée une gorge latérale nécessaire au passage du galet de guidage ou de roulage.According to the invention, the guide or rolling rail is, prior to laying, partially coated, over substantially its entire length, with a lining material, forming a coating which comprises at least one lateral extension intended to rest on the material sealing and in which is provided a lateral groove necessary for the passage of the guide roller or rolling.

Selon une autre caractéristique essentielle de l'invention, le rail de guidage ou de roulage est directement bloqué et maintenu par la matière de scellement sans avoir recours à un dispositif intermédiaire assurant une fixation supplémentaire.According to another essential characteristic of the invention, the rail of guiding or rolling is directly blocked and held by the sealing material without resorting to an intermediate device providing additional fixation.

La matière de garnissage utilisée présente préférentiellement des propriétés de compressibilité lui permettant d'assurer, lors du passage du galet de guidage ou de roulage, l'évacuation, l'enfoncement ou l'incrustation des objets pouvant se trouver dans la gorge latérale.The packing material used preferably has compressibility properties enabling it to ensure, during the passage of the guide or rolling roller, the evacuation, the insertion or the incrustation of the objects that may be in the lateral groove.

Selon un mode de réalisation préférentiel du support de roulage ou de guidage selon l'invention, le rail de guidage ou de roulage est directement cintré à la pose sur son site d'implantation, sans étape indépendante supplémentaire de cintrage.According to a preferred embodiment of the rolling or guiding support according to the invention, the guide or rolling rail is directly bent to the laying on its implantation site, without additional independent bending step.

Le rail selon l'invention sort d'usine pourvu de son enrobage de matière de garnissage. Il est réalisé dans des conditions stables et optimales. La composition et la géométrie de la matière de garnissage peuvent donc être parfaitement maîtrisées et reproductibles, assurant ainsi au rail enrobé une bonne régularité dimensionnelle.The rail according to the invention leaves the factory provided with its coating of packing material. It is performed in stable and optimal conditions. The composition and geometry of the packing material can therefore be perfectly controlled and reproducible, thus ensuring the coated rail a good dimensional regularity.

Cet enrobage est préférentiellement collé, adhérisé ou vulcanisé autour du rail, ce qui confère en plus une protection anticorrosion au rail. Le rail peut ainsi être décalaminé, par grenaillage ou autre, puis si besoin recouvert d'une peinture ou d'une couche d'accrochage, puis revêtu de son enrobage. D'autres procédés de liaison entre enrobage et rail sont également possibles.This coating is preferably glued, adhered or vulcanized around the rail, which also gives an anti-corrosion protection to the rail. The rail can thus be descaled, by shot blasting or other, then if necessary covered with a paint or a layer of attachment, and then coated with its coating. Other methods of bonding between coating and rail are also possible.

Les tronçons droits de rail, revêtus de leur masse d'enrobage, sont ensuite livrés et mis en place facilement sur le lieu du chantier.Straight sections of rail, coated with their coating material, are then delivered and easily placed on site.

Le rail selon l'invention présente une section de forme préférentiellement élancée, par exemple une section de forme générale en I, sans inertie latérale importante, ce qui lui permet de se cintrer automatiquement à la pose sur son site d'implantation.The rail according to the invention has a section of preferably slender shape, for example a section of generally I-shaped, without significant lateral inertia, which allows it to bend automatically to the laying on its implantation site.

L'étape indépendante supplémentaire de cintrage, à la fabrication ou peu avant la pose, des rails classiques à semelle est ainsi évitée. Une telle opération indépendante de cintrage, réalisée généralement par roulage de galets, pourrait en outre abîmer l'enrobage.The additional independent step of bending, to manufacture or shortly before laying, conventional rails with sole is thus avoided. Such an independent bending operation, generally performed by roller rolling, could further damage the coating.

Le rail de l'invention est avantageusement prévu sans semelle, ou sans semelle ou base importante en partie inférieure et de hauteur plus grande que le rail de l'art antérieur. L'épaisseur de matière de garnissage bordant les flancs latéraux du rail est ainsi beaucoup plus importante que dans l'art antérieur. Toutefois, la quantité totale de matière de garnissage est pratiquement équivalente, ce qui permet de ne pas générer de surcoût important pour cette solution.The rail of the invention is advantageously provided without sole, or without sole or substantial base in the lower part and of greater height than the rail of the prior art. The thickness of packing material bordering the lateral flanks of the rail is thus much greater than in the prior art. However, the total amount of packing material is practically equivalent, which makes it possible not to generate significant additional costs for this solution.

Par sa forme avantageuse ne comportant plus de semelle ou simplement une base élargie, et grâce à l'épaisseur plus importante de matière de garnissage, le rail selon l'invention permet en outre d'améliorer l'enfoncement des objets de taille assez importante.By its advantageous form no longer having a sole or simply an enlarged base, and thanks to the greater thickness of material of In addition, the rail according to the invention makes it possible to improve the penetration of relatively large objects.

Par ailleurs, le rail de guidage selon l'invention peut être mis en place sur son site d'exploitation, suivant plusieurs procédés de pose, dont deux exemples seront détaillés par la suite, satisfaisant à la fois aux exigences des travaux publics et à celles de la sécurité des véhicules urbains de transport en commun guidés par rail de guidage.Furthermore, the guide rail according to the invention can be set up on its operating site, according to several laying methods, two examples of which will be detailed later, satisfying both the requirements of the public works and those the safety of public transit vehicles guided by guide rail.

Dans tous les cas, le rail de guidage ou de roulage est directement mis en place dans la matière de scellement et retenu dans ou par celle-ci sans dispositif de maintien intermédiaire.In all cases, the guide rail or rolling is directly placed in the sealing material and retained in or by the latter without intermediate holding device.

On se dispense ainsi des dispositifs de fixation de différentes natures, utilisés dans l'art antérieur pour réaliser la fixation du rail dans le fond de l'engravure à intervalles réguliers.This eliminates the fixing devices of different types used in the prior art to achieve the fixing of the rail in the bottom of the engravure at regular intervals.

La pose du rail est de ce fait plus rapide et plus économique. Cela permet en outre à l'enrobage d'être continu sur sensiblement toute la longueur du rail ou du tronçon de rail. Il peut ainsi remplir sa fonction sur sensiblement toute la longueur du rail sans interruptions liées à la présence de dispositifs de fixation.The installation of the rail is therefore faster and more economical. This further allows the coating to be continuous over substantially the entire length of the rail or the rail section. It can thus perform its function over substantially the entire length of the rail without interruptions related to the presence of fasteners.

En se référant à la figure 1 annexée, on décrira ci-dessous un exemple de support de guidage selon l'art antérieur.Referring to the figure 1 attached, will be described below an example of guide support according to the prior art.

Un rail de guidage 1 est mis en place dans une engravure 2 creusée dans le sol 3 et garnie d'une matière de scellement 4, classiquement du béton.A guide rail 1 is set up in a groove 2 dug in the ground 3 and lined with a sealing material 4, typically concrete.

Le rail de guidage 1 comporte en partie inférieure une semelle d'appui 5 qui repose dans l'engravure 2 sur une couche de béton de manière que la surface supérieure 6 du rail 1 affleure avec ou dépasse légèrement le niveau du sol 3 en vue du guidage de véhicules urbains de transport en commun.The guide rail 1 comprises in the lower part a support plate 5 which rests in the engravure 2 on a layer of concrete so that the upper surface 6 of the rail 1 is flush with or slightly exceeds the ground level 3 in view of guiding urban transit vehicles.

Selon une originalité protégée précédemment, l'espace existant entre la matière de scellement 4 et les flancs 7 du rail de guidage 1 est avantageusement comblé, après la pose du rail dans l'engravure, par une matière de garnissage 8 laissant cependant libres les gorges 9 nécessaires au passage du ou des galets de guidage des véhicules.According to an originality previously protected, the space between the sealing material 4 and the flanks 7 of the guide rail 1 is advantageously filled, after the installation of the rail in the engravure, by a lining material 8 however leaving free the grooves 9 necessary for the passage of the guide roller or rollers of the vehicles.

Plusieurs modes de réalisation préférés du support de guidage ou de roulage selon l'invention, comprenant un rail de guidage ou de roulage 10 et une engravure 2 remplie d'une matière de scellement 4, vont maintenant être décrits de façon détaillée en référence aux figures 2 à 16. Les éléments équivalents représentés sur les différentes figures porteront les mêmes références numériques.Several preferred embodiments of the guide or running support according to the invention, comprising a guide or rolling rail 10 and an engravure 2 filled with a sealing material 4, will now be described in detail with reference to FIGS. Figures 2 to 16 . The equivalent elements represented in the different figures will bear the same numerical references.

On définira dans la suite de cette description les notions de haut et de bas, d'inférieur et de supérieur, de tête et de base, etc..., en fonction de l'orientation adoptée par le rail représenté sur les différentes figures. Il est évident que cette orientation ne sera pas forcément conservée en utilisation, notamment s'il s'agit d'un rail de guidage latéral.In the remainder of this description, the notions of top and bottom, bottom and top, head and base, etc. will be defined as a function of the orientation adopted by the rail shown in the various figures. It is obvious that this orientation will not necessarily be retained in use, especially if it is a lateral guide rail.

Par engravure, nous entendons ici toute gorge, rainure ou canal formé dans le sol ou tout autre support et prévu pour la réception d'un ou plusieurs rail(s) immobilisé(s) dans une matière de scellement, préférentiellement du béton.By engravure, we mean here any groove, groove or channel formed in the ground or any other support and intended to receive one or more rail (s) immobilized (s) in a sealing material, preferably concrete.

Il peut également s'agir d'une goulotte partiellement ou totalement enterrée dans, ou posée sur le sol ou un autre support, ou plus généralement de toute structure linéaire de voie formant fondation pour la mise en place et l'immobilisation d'un ou plusieurs rails.It may also be a chute partially or totally buried in, or placed on the ground or another support, or more generally any linear structure of foundation track for the establishment and immobilization of one or several rails.

De la même façon, bien que cette engravure soit préférentiellement placée au niveau du sol, elle peut également être située ailleurs et notamment sur une paroi latérale bordant la voie de circulation d'un véhicule urbain de transport en commun à guidage latéral.Similarly, although this engravure is preferably placed at ground level, it can also be located elsewhere and in particular on a side wall bordering the taxiway of a public transit vehicle with lateral guidance.

Sur les modes préférentiels de réalisation représentés, le rail 10 selon l'invention présente une section de forme générale en I dont les extrémités, à savoir une tête 11, ou champignon, et une base 12, sont réunies par une âme 13 allongée et étroite formant l'axe du I.On the preferred embodiments shown, the rail 10 according to the invention has a generally I-shaped section whose ends, namely a head 11, or mushroom, and a base 12, are joined by an elongate and narrow core 13 forming the axis of I.

La tête 11 et la base 12 du rail 10 selon l'invention sont préférentiellement sensiblement symétriques par rapport au plan transversal médian du rail.The head 11 and the base 12 of the rail 10 according to the invention are preferably substantially symmetrical with respect to the median transverse plane of the rail.

La tête 11 du rail 10 présente une forme extérieure quelconque adaptée à la fonction quelle doit remplir selon l'application du rail 10. Elle comporte ainsi par exemple un ou plusieurs chant(s) 14 approprié(s) pour servir de piste de roulement pour le ou les galets de guidage ou de roulage 15 du véhicule.The head 11 of the rail 10 has any external shape adapted to the function that must be fulfilled according to the application of the rail 10. It thus comprises for example one or more singing (s) 14 suitable (s) to serve as a track for the roller or guide rollers 15 of the vehicle.

Le rail 10 représenté est préférentiellement plus haut que le rail 1 de l'art antérieur et ne comporte pas de semelle d'appui 5 en partie basse. Il présente ainsi une certaine souplesse qui lui permet de s'adapter aux courbes du tracé.The rail 10 shown is preferably higher than the rail 1 of the prior art and has no support plate 5 at the bottom. It has a certain flexibility that allows it to adapt to the curves of the route.

De ce fait, il peut avantageusement être fabriqué et livré uniquement en tronçons droits, ces derniers pouvant être courbés avant ou à la pose si nécessaire pour suivre le tracé prévu et par exemple s'auto-cintrer par enfoncement dans une rainure à tracé courbe.Therefore, it can advantageously be manufactured and delivered only straight sections, the latter can be bent before or laying if necessary to follow the planned course and for example self-bending by driving into a groove curved path.

La conformation du rail 10 est de préférence symétrique par rapport à son plan longitudinal médian en vue d'éviter tout déversement ou torsion du rail lors de sa pose dans les courbes.The conformation of the rail 10 is preferably symmetrical with respect to its median longitudinal plane in order to avoid any spillage or twisting of the rail during its installation in the curves.

La forme du rail 10 selon l'invention peut cependant être différente de celle représentée, du moment qu'elle est adaptée à la fonction de guidage ou de roulage que le rail doit remplir et qu'elle permet de préférence un cintrage sur site à la pose du rail de guidage ou un autocintrage par déformation du rail à la pose.The shape of the rail 10 according to the invention may, however, be different from that shown, as long as it is adapted to the guiding or rolling function that the rail has to fulfill and that it preferably allows on-site bending to the installation of the guide rail or autoclamping by deformation of the rail when laying.

On peut ainsi imaginer par exemple un rail sans base 12 et à âme 13 plate d'épaisseur fine, ou même un rail plat à section de forme générale sensiblement rectangulaire, c'est-à-dire à section de largeur quasi-constante sur toute sa hauteur, et par exemple en lame.We can thus imagine for example a rail without base 12 and core 13 flat of thin thickness, or even a flat rail section of generally rectangular general shape, that is to say, section of substantially constant width over its entire height, and for example blade.

De préférence, le rail 10 selon l'invention ne présente pas d'inertie latérale importante, afin de pouvoir être cintré à la pose sur son site d'implantation, sans étape indépendante supplémentaire de cintrage.Preferably, the rail 10 according to the invention does not have significant lateral inertia, so as to be bent to the laying on its implantation site, without additional independent bending step.

Une variante de base de l'invention a été représentée sur la figure 2.A basic variant of the invention has been represented on the figure 2 .

Selon cette variante, le rail comporte une extension latérale 16 de matière de garnissage 8, préférentiellement remontante et destinée à reposer sur la matière de scellement 4, dans laquelle est ménagée une gorge latérale 9 nécessaire au passage d'un galet de guidage ou de roulage 15 et plus particulièrement de son mentonnet 17.According to this variant, the rail comprises a lateral extension 16 of packing material 8, preferably upward and intended to rest on the sealing material 4, in which is provided a lateral groove 9 necessary for the passage of a guide roller or rolling 15 and more particularly of its lug 17.

On remarquera que dans cette version par exemple, le galet de guidage peut être aussi un galet ou une roue porteuse, classiquement rencontré dans le ferroviaire.It will be noted that in this version for example, the guide roller may also be a roller or a load wheel, conventionally encountered in the railway.

Selon un mode de réalisation préférentiel de l'invention représenté sur les figures 3 à 16, cette extension latérale 16 de matière de garnissage 8 fait partie d'un enrobage 18 plus complet de matière de garnissage 8.According to a preferred embodiment of the invention shown in the Figures 3 to 16 this lateral extension 16 of packing material 8 is part of a more complete coating 18 of packing material 8.

De préférence, le rail 10 peut ainsi être enrobé d'une masse de matière de garnissage 8 au niveau de sa partie médiane et inférieure, à savoir sur les variantes préférentielles représentées au niveau de son âme 13 et de sa base 12.Preferably, the rail 10 can thus be coated with a mass of packing material 8 at its median and lower part, namely on the preferred variants represented at its core 13 and its base 12.

La partie supérieure du rail 10, correspondant sensiblement à sa tête 11, est laissée libre sans enrobage pour ne pas interférer avec ses zones fonctionnelles. L'accès aux chants 14 est ainsi possible et une ou plusieurs gorges latérales 9 peuvent être conformées de façon à ne pas gêner l'emprise dynamique des galets 15.The upper part of the rail 10, substantially corresponding to its head 11, is left free without coating so as not to interfere with its functional areas. Access to the edges 14 is thus possible and one or more lateral grooves 9 may be shaped so as not to interfere with the dynamic grip of the rollers 15.

De préférence, la forme de l'enrobage 18 suit sensiblement les contours du rail 10. L'enrobage 18 comporte ainsi, sur les exemples représentés, un renflement inférieur 19 prolongé par une partie centrale 20 préférentiellement mince et allongée.Preferably, the shape of the coating 18 substantially follows the contours of the rail 10. The coating 18 thus comprises, in the examples shown, a lower bulge 19 extended by a central portion 20 preferably thin and elongated.

La partie centrale 20 de l'enrobage 18 s'évase en partie supérieure pour former au moins une extension latérale 16 préférentiellement remontante et destinée à reposer sur la matière de scellement 4.The central part 20 of the coating 18 flares out at the top to form at least one lateral extension 16 which is preferably upward and intended to rest on the sealing material 4.

Selon le modèle de rail 10 et son application, une extension latérale 16 peut être prévue de chaque côté du rail 10 de manière à former deux gorges latérales 9.According to the rail model 10 and its application, a lateral extension 16 can be provided on each side of the rail 10 so as to form two lateral grooves 9.

Comme on peut le voir sur les figures 3 à 16, la masse de matière de garnissage 8 bordant les flancs 21 du rail 10 représenté est beaucoup plus profonde que celle de l'art antérieur. Des objets de taille nettement supérieure peuvent avantageusement s'y enfoncer et/ou s'y incruster afin de ne pas entraver la circulation du ou des galets de guidage ou de roulage 15 du véhicule.As can be seen on the Figures 3 to 16 , the mass of packing material 8 bordering the flanks 21 of the rail 10 shown is much deeper than that of the prior art. Objects of a much larger size can advantageously sink and / or embed itself so as not to impede the circulation of the guide roller or roller 15 of the vehicle.

La matière de garnissage 8 est une matière synthétique appropriée quelconque, suffisamment élastique pour remplir la fonction décrite précédemment et adaptée pour résister aux conditions climatiques extérieures et aux conditions d'utilisation auxquelles elle sera soumise dans cette application.The packing material 8 is any suitable synthetic material, sufficiently elastic to perform the function previously described and adapted to withstand the external climatic conditions and the conditions of use to which it will be subjected in this application.

Elle est choisie de sorte à ne jamais interférer avec l'emprise des galets 15, quelles que soient les conditions d'environnement, notamment climatiques et les conditions d'utilisation du véhicule dans les limites prescrites par le constructeur. En particulier, elle ne gonfle ou ne se dilate que très peu, même sous l'effet des variations thermiques et des précipitations.It is chosen so as never to interfere with the grip of the rollers 15, whatever the environmental conditions, including climatic conditions and the conditions of use of the vehicle within the limits prescribed by the manufacturer. In particular, it swells or expands very little, even under the effect of thermal variations and precipitation.

Avantageusement, cette matière peut être prévue pour isoler électriquement le rail 10 du sol. Dans ce cas, le rail 10 est préférentiellement enrobé sur toute sa partie en contact avec le sol. Pour un rail enterré, par exemple comme celui représenté sur les figures 6 et 7, l'enrobage 18 isolant recouvre complètement la partie inférieure et médiane du rail.Advantageously, this material may be provided to electrically isolate the rail 10 from the ground. In this case, the rail 10 is preferably coated on all its part in contact with the ground. For a buried rail, for example as shown on Figures 6 and 7 , the insulating coating 18 completely covers the lower and middle part of the rail.

Cependant et comme déjà indiqué précédemment, un revêtement 18 aussi étendu n'est pas indispensable à l'invention, ce dernier pouvant notamment ne couvrir qu'un seul côté du rail 10 ou uniquement sa partie médiane en laissant libre sa base 12 d'appui, ou encore par exemple qu'une très faible superficie du rail limitée à la zone entourant la gorge latérale 9 comme sur la variante de base de la figure 2.However, and as already indicated above, a coating 18 so extensive is not essential to the invention, the latter may in particular cover only one side of the rail 10 or only its middle part leaving free its base 12 support , or for example that a very small area of the rail limited to the area surrounding the lateral groove 9 as on the basic variant of the figure 2 .

Selon une caractéristique essentielle de l'invention, le rail 10 est enrobé de sa couche de matière de garnissage 8 avant sa pose sur son lieu d'utilisation.According to an essential characteristic of the invention, the rail 10 is coated with its layer of packing material 8 before being placed in its place of use.

Cet enrobage 18 de matière de garnissage 8 est avantageusement continu sur sensiblement toute la longueur du rail ou du tronçon de rail. Le rail de guidage étant directement mis en place dans l'engravure 2 et retenue par la matière de scellement 4, il n'est en effet pas nécessaire de prévoir d'interruptions de cet enrobage pour la pose de dispositifs intermédiaires de fixation.This coating 18 of packing material 8 is advantageously continuous over substantially the entire length of the rail or the rail section. The guide rail being directly placed in the engravure 2 and retained by the sealing material 4, it is indeed not necessary to provide interruptions of this coating for the installation of intermediate fixing devices.

La fonction d'évacuation, d'enfoncement ou d'incrustation des corps étrangers se trouvant dans la gorge latérale 9, assurée par la matière de garnissage 8, peut ainsi avantageusement être remplie sur toute la longueur du rail de guidage 10.The function of evacuating, depressing or incrusting the foreign bodies in the lateral groove 9, provided by the packing material 8, can thus advantageously be filled over the entire length of the guide rail 10.

L'enrobage 18 est préférentiellement rapporté ou formé autour du rail lors de sa fabrication ou après celle-ci, par exemple par extrusion de la matière de garnissage 8 autour du rail 10. L'enrobage 18 de matière de garnissage 8 peut ainsi avantageusement être réalisé en usine dans des conditions stables et optimales, ce qui garantit une composition et une géométrie maîtrisées et reproductibles.The coating 18 is preferably added or formed around the rail during its manufacture or after it, for example by extrusion of the packing material 8 around the rail 10. The coating 18 of packing material 8 can thus advantageously be achieved in the factory in stable and optimal conditions, which guarantees a controlled and reproducible composition and geometry.

Les tronçons de rail 10 revêtus de leur couche d'enrobage 18 sont ensuite livrés et mis en place sur le lieu du chantier.The sections of rail 10 coated with their coating layer 18 are then delivered and put in place at the work site.

Comme dans l'art antérieur, le rail enrobé 10 selon l'invention est mis en place dans une engravure 2, par exemple creusée dans le sol 3 et remplie d'une matière de scellement 4, préférentiellement du béton.As in the prior art, the coated rail 10 according to the invention is put in place in an engravure 2, for example dug in the ground 3 and filled with a sealing material 4, preferably concrete.

Cependant, aucun dispositif intermédiaire n'est utilisé pour assurer la fixation du rail 10 dans l'engravure 2. Celui-ci est directement bloqué et maintenu par la matière de scellement 4.However, no intermediate device is used to secure the rail 10 in the engravure 2. This is directly blocked and maintained by the sealing material 4.

Deux exemples de rail enrobé 10 selon l'invention ont été représentés en position d'utilisation au sol sur les figures 6 et 7.Two examples of coated rail 10 according to the invention have been shown in the position of use on the ground on the Figures 6 and 7 .

Pour la pose du rail 10 de l'invention, les présents inventeurs ont mis au point deux procédés préférentiels qui sont illustrés respectivement sur les figures schématiques 11 à 13 et 14 à 16.For the installation of the rail 10 of the invention, the present inventors have developed two preferred methods which are illustrated respectively in the schematic figures 11 to 13 and 14 to 16.

Selon un premier procédé de pose dont les étapes sont représentées sur les figures 11 à 13, le rail enrobé 10 peut être placé dans l'engravure 2 avant que l'on ne commence à la remplir de matière de scellement 4 ou alors qu'elle n'est que partiellement remplie (figure 11).According to a first laying method, the steps of which are represented on the Figures 11 to 13 , the coated rail 10 can be placed in the engravure 2 before it starts to fill it with sealing material 4 or when it is only partially filled ( figure 11 ).

Le rail enrobé 10 doit alors être positionné précisément au niveau de son emplacement définitif et y être maintenu provisoirement par un dispositif de maintien temporaire 22 adapté quelconque. Sur les figures, ce dispositif de maintien temporaire 22 a été représenté schématiquement par une pince. Sa forme et sa nature peuvent néanmoins être très différentes.The coated rail 10 must then be positioned precisely at its final location and be temporarily held there by any suitable temporary holding device 22. In the figures, this temporary holding device 22 has been schematically represented by a clamp. Its shape and its nature can nevertheless be very different.

On coule ensuite dans l'engravure 2 du béton ou toute autre matière de scellement 4 souhaitée, selon des techniques connues et parfaitement maîtrisées quelles que soient les conditions météorologiques du moment (figure 12). La matière de scellement 4 se répand autour du rail 10 et de son enrobage 18 et remplit l'engravure jusqu'au niveau final souhaité.Then poured into the engravure 2 of the concrete or any other sealing material 4 desired, according to known techniques and perfectly controlled whatever the weather conditions of the moment ( figure 12 ). The sealing material 4 spreads around the rail 10 and its coating 18 and fills the engravure to the desired final level.

Après séchage et durcissement, la matière de scellement 4 assure le maintien du rail 10 par l'intermédiaire de son enrobage 18 de matière de garnissage et de maintien 8. Le dispositif provisoire de maintien 22, n'étant plus nécessaire, peut alors être retiré.After drying and hardening, the sealing material 4 maintains the rail 10 by means of its coating 18 of filling and holding material 8. The temporary holding device 22, no longer being necessary, can then be removed. .

Dans ce cas et selon les variantes de l'invention représentées sur les figures 3 et 5, un moyen d'adhérence ou d'accrochage 23, notamment sous la forme d'un traitement de surface ou d'éléments en relief ou d'évidements, par exemple des fibres saillantes, préférentiellement métalliques ou synthétiques, peut avantageusement être prévu à la surface extérieure de l'enrobage 18, pour améliorer la liaison entre la matière de scellement 4 et la matière de garnissage 8 à l'interface entre ces deux matières.In this case and according to the variants of the invention represented on the Figures 3 and 5 an adhesion or fastening means 23, in particular in the form of a surface treatment or of elements in relief or recesses, for example protruding fibers, preferably metallic or synthetic fibers, may advantageously be provided for in FIG. outer surface of the coating 18, to improve the connection between the material 4 and the packing material 8 at the interface between these two materials.

Un exemple de moyen d'adhérence 23 a été représenté sur la vue en perspective de la figure 5. Il s'agit dans ce cas d'un fil de fer 24 conformé selon une série de vagues successives et noyé à la périphérie de l'enrobage 18 de manière qu'une succession de boucles 25 dépassent de ce dernier pour faciliter l'accrochage avec la matière de scellement 4.An example of adhesion means 23 has been shown in the perspective view of the figure 5 . In this case, it is a wire 24 shaped according to a series of successive waves and embedded in the periphery of the coating 18 so that a succession of loops 25 protrude from the latter to facilitate the attachment with the sealing material 4.

Ce moyen d'adhérence 23 est de préférence situé principalement au niveau de l'extrémité libre 26 de l'extension ou des extensions latérale(s) 16, qui se trouve dans la zone d'interface où l'effort d'écartement est le plus important en utilisation, notamment en raison du roulage transversal des véhicules traversant la voie de guidage.This adhesion means 23 is preferably located mainly at the free end 26 of the extension or lateral extensions 16, which is in the interface zone where the spreading force is the more important in use, especially because of the transversal rolling of vehicles crossing the guide path.

Ce moyen d'adhérence 23 peut cependant être présent n'importe où sur la surface extérieure de l'enrobage 18, localement ou sur la totalité de cette surface extérieure.This adhesion means 23 may however be present anywhere on the outer surface of the coating 18, locally or on the whole of this outer surface.

Ce moyen d'adhérence 23 peut également être réalisé sous la forme d'un traitement de surface approprié ou par l'utilisation d'une matière cellulaire ou agglomérée pour la matière de garnissage 8.This adhesion means 23 can also be realized in the form of a suitable surface treatment or by the use of a cellular or agglomerated material for the packing material 8.

Selon le deuxième procédé de pose représenté sur les figures 14 à 16, on remplit l'engravure 2 de matière de scellement 4 avant la mise en place du rail enrobé 10, en ménageant dans la matière de scellement 4, par exemple par coffrage glissant pendant le remplissage de l'engravure, un canal 27 préférentiellement évasé vers le bas et de forme sensiblement complémentaire à la forme extérieure du rail 10 muni de son enrobage 18 (figure 14).According to the second laying method represented on the Figures 14 to 16 the filling 2 is filled with sealing material 4 before the coated rail 10 is put in place, by providing in the sealing material 4, for example by sliding formwork during the filling of the engraving, a channel 27 preferably flared to the bottom and substantially complementary shape to the outer shape of the rail 10 provided with its coating 18 ( figure 14 ).

Selon une autre variante non représentée, le canal 27 peut également être réalisé après le remplissage de l'engravure 2, par rainurage de la matière de scellement 4 présente dans l'engravure 2.According to another variant not shown, the channel 27 can also be made after the filling of the engravure 2, by grooving the sealing material 4 present in the engravure 2.

Après séchage et durcissement de la matière de scellement, le rail 10 enrobé de l'invention est enfoncé à force jusqu'à encastrement dans ce canal 27, par exemple au moyen d'un rouleau compresseur (figure 15).After drying and hardening of the sealing material, the coated rail 10 of the invention is force-fitted until it is embedded in this channel 27, for example by means of a steam roller ( figure 15 ).

Cet enfoncement s'accompagne dans les courbes d'un cintrage progressif du rail. Il s'agit d'un véritable auto-cintrage au cours duquel le cintrage définitif nécessaire est obtenu en fin d'enfoncement. Grâce aux caractéristiques du rail, le cintrage s'effectue sans verser, c'est-à-dire sans inclinaison de la partie supérieure du rail.This depression is accompanied in the curves of a progressive bending of the rail. This is a true self-bending in which the final bending required is obtained at the end of penetration. Thanks to the characteristics of the rail, the bending is carried out without pouring, that is to say without inclination of the upper part of the rail.

L'enfoncement à force du rail 10, rendu possible par la nature compressible de la matière de garnissage 8, peut être facilité par une conformation extérieure adaptée de l'enrobage 18 et notamment de son renflement inférieur 19.Depression by force of the rail 10, made possible by the compressible nature of the packing material 8, can be facilitated by a suitable external conformation of the coating 18 and in particular of its lower bulge 19.

Le renflement inférieur 19 de l'enrobage présente ainsi par exemple des chants biseautés 28 formant des rampes inclinées d'engagement, convergeant vers le bas pour guider l'engagement du rail 10.The lower bulge 19 of the coating thus has, for example, beveled edges 28 forming inclined engagement ramps, converging downwards to guide the engagement of the rail 10.

Le resserrement local ou étranglement de la partie centrale 20 de l'enrobage 18 rend cet encastrement autobloquant.The local tightening or throttling of the central portion 20 of the coating 18 makes this recess self-locking.

Un retrait accidentel ou malveillant du rail 10 hors du canal 27 est empêché par l'effort d'extension latérale de la matière de garnissage 8, qui se trouve, lors du montage à force, précontrainte en compression notamment au niveau de l'étranglement de la partie centrale 20, du fait de la géométrie et des dimensions respectives de l'enrobage 18 et du canal 27. Les saillies 29 du renflement inférieur 19 s'opposent également à un tel retrait.An accidental or malicious removal of the rail 10 from the channel 27 is prevented by the lateral expansion force of the packing material 8, which is, during the press fitting, prestressing in compression, especially at the level of the throttle. the central portion 20, because of the geometry and the respective dimensions of the coating 18 and the channel 27. The projections 29 of the lower bulge 19 also oppose such withdrawal.

Le rail 10 offre ainsi une retenue à l'arrachement et si les galets enserrent le rail, le système de guidage se trouve ancré au sol.The rail 10 thus provides a pull-back restraint and if the rollers enclose the rail, the guide system is anchored to the ground.

En cas de problème, le rail 10 selon l'invention peut être facilement démonté. Pour cela, il suffit de découper par le haut la matière de garnissage 8 de part et d'autre du rail 10 afin de pouvoir extraire celui-ci de son logement.In case of problems, the rail 10 according to the invention can be easily dismantled. For this, it is sufficient to cut from above the packing material 8 on either side of the rail 10 in order to extract it from its housing.

Dans le cas où le rail enrobé 10 a été placé par encastrement dans un canal 27 de forme complémentaire (figures 14 à 16), les portions restantes de matière de garnissage 8 peuvent être, à leur tour, très facilement enlevées une fois le tronçon de rail extrait, car toute compression latérale disparaît alors.In the case where the coated rail 10 has been placed by embedding in a channel 27 of complementary shape ( Figures 14 to 16 ), the remaining portions of lining material 8 can, in turn, be very easily removed once the rail section extracted, because any lateral compression then disappears.

Le tronçon de rail démonté peut ensuite être remplacé par un nouveau tronçon de rail 10 enrobé selon l'invention en utilisant la même méthode de pose.The disassembled rail section can then be replaced by a new coated rail section according to the invention using the same method of laying.

Dans le cas où le rail enrobé 10 a été ancré en coulant la matière de scellement autour de lui (figures 11 à 13), les portions restantes de matière de garnissage 8 continuent à adhérer à la matière de scellement une fois le tronçon de rail 10 extrait.In the case where the coated rail 10 has been anchored by casting the sealing material around it ( Figures 11 to 13 ), the remaining portions of packing material 8 continue to adhere to the sealing material once the rail section 10 is extracted.

Le tronçon de rail doit alors être localement remplacé par un tronçon de rail non enrobé, la jonction et le comblement entre ce tronçon et les portions restantes de matière de garnissage 8 ancrées dans la matière de scellement s'effectuant classiquement par coulage de résine.The rail section must then be locally replaced by an uncoated rail section, the junction and the filling between this section and the remaining portions of packing material 8 anchored in the sealing material conventionally performed by casting resin.

Cette méthode peut également être utilisée au niveau des soudures des rails, où le rail est dénudé partiellement pour permettre la soudure, ou autres fixations mécaniques si nécessaire.This method can also be used at the rail welds, where the rail is partially stripped to allow welding, or other mechanical fasteners if necessary.

On peut également imaginer qu'aucune fixation ne soit nécessaire entre les tronçons adjacents, le rail étant suffisamment maintenu pour permettre un alignement et donc un guidage correct du véhicule.It is also conceivable that no fastening is necessary between the adjacent sections, the rail being sufficiently maintained to allow alignment and thus correct guidance of the vehicle.

De manière évidente, l'invention ne se limite pas aux modes de réalisation et de pose préférentiels représentés et décrits, l'homme du métier pouvant y apporter de nombreuses modifications et imaginer d'autres variantes sans sortir de cette idée inventive.Obviously, the invention is not limited to the preferred embodiments and laying represented and described, the skilled person can make many changes and imagine other variants without departing from this inventive idea.

Par exemple, bien que la matière de scellement 4 soit préférentiellement du béton, à la place de ce dernier, on pourra utiliser toute autre matière permettant d'immobiliser le rail enrobé 10 dans une engravure 2.For example, although the sealing material 4 is preferably concrete, instead of the latter, it will be possible to use any other material for immobilizing the coated rail 10 in an engravure 2.

En outre, l'invention pourra être adaptée par l'homme du métier à tout type de rail de guidage ou de roulage 10 pour véhicule de transport en commun sans limitation à un système particulier de guidage ou de roulage.In addition, the invention may be adapted by the skilled person to any type of guide rail or taxi 10 for public transport vehicle without limitation to a particular system for guiding or taxiing.

Les figures 8 à 10 illustrent, de façon non exhaustive ou limitative, l'application de l'invention à trois systèmes de guidage différents.The Figures 8 to 10 illustrate, in a non-exhaustive or limiting manner, the application of the invention to three different guidance systems.

Sur la figure 8, une variante du rail enrobé 10 selon l'invention est en prise avec un système de guidage 30 comportant deux galets inclinés 31 en V roulant sur des pistes de roulement 14 inclinées au niveau de la partie supérieure de la tête 11 du rail de guidage 10.On the figure 8 , a variant of the coated rail 10 according to the invention is engaged with a guide system 30 comprising two inclined rollers 31 V rolling on rolling tracks 14 inclined at the upper part of the head 11 of the guide rail 10 .

Les mentonnets 32 de chacun des galets inclinés de guidage 31 s'étendent de part et d'autre de la tête 11 du rail jusque sous les flancs en saillie 33 de celle-ci. Ils circulent dans les gorges latérales 9 ménagées dans la matière compressible des extensions latérales 16 de l'enrobage 18, sous la tête 11 du rail et de chaque côté de celle-ci.The lugs 32 of each of the inclined guide rollers 31 extend on either side of the head 11 of the rail to below the projecting flanks 33 thereof. They circulate in the lateral grooves 9 formed in the compressible material of the lateral extensions 16 of the coating 18, under the head 11 of the rail and on each side thereof.

Le mode de réalisation de la figure 9 est adapté à un galet de guidage 34 prévu pour coopérer avec un rail à gorge. La bande de roulement 35 du galet 34 roule sur la surface supérieure plane 36 du rail de guidage 10 qui lui sert de piste de roulement.The embodiment of the figure 9 is adapted to a guide roller 34 provided to cooperate with a grooved rail. The tread 35 of the roller 34 rolls on the flat upper surface 36 of the guide rail 10 which serves as a raceway.

Ce type de galet 34 est pourvu sur un seul de ses côtés d'un mentonnet 37 formant un rebord périphérique. Ce mentonnet 37 se déplace le long d'une unique gorge latérale 9 de guidage, formée au moyen de l'enrobage 18 selon l'invention qui borde latéralement l'un des côtés de la tête 11 du rail par une extension latérale 16 reproduisant la géométrie d'un rail à gorge conventionnel.This type of roller 34 is provided on one of its sides with a lug 37 forming a peripheral rim. This latch 37 moves along a single lateral guide groove 9 formed by means of the coating 18 according to the invention which laterally borders one of the sides of the head 11 of the rail by a lateral extension 16 reproducing the geometry of a conventional throat rail.

Le galet de guidage 38 de la figure 10 comporte deux mentonnets 39, formant un rebord périphérique de chaque côté de sa bande de roulement 40.The guide roller 38 of the figure 10 has two lugs 39, forming a peripheral rim on each side of its tread 40.

La variante du rail de guidage 10 représentée sur la figure 10 est destinée à coopérer avec ce type de galet. Elle est similaire à celle de la figure 9, mais comporte une extension latérale 16 d'enrobage de chaque côté de la tête de rail 11, de manière à pouvoir réaliser une gorge 9 bordant latéralement la tête de rail 11 de chaque côté de celle-ci, permettant la circulation des deux mentonnets 39.The variant of the guide rail 10 shown on the figure 10 is intended to cooperate with this type of roller. It is similar to that of the figure 9 but has a lateral extension 16 of coating on each side of the rail head 11, so as to make a groove 9 bordering laterally the rail head 11 of each side of it, allowing the circulation of the two chins 39.

Le rail de guidage ou de roulage 10 selon l'invention peut évidemment comporter d'autres modifications sans sortir de l'idée générale inventive. Par exemple, l'enrobage 18 peut inclure un ou plusieurs insert(s) de matière différente, tels que 41 sur les figures 8 à 10. Ces inserts peuvent être affleurants ou noyés dans la matière de garnissage 8 formant l'enrobage 18. Ils peuvent également être prévus saillant à l'extérieur de celui-ci.The guide rail or taxi 10 according to the invention can obviously include other modifications without departing from the general idea inventive. For example, the coating 18 may include one or more insert (s) of different material, such as 41 on the Figures 8 to 10 . These inserts may be flush or embedded in the lining material 8 forming the coating 18. They may also be provided projecting outside thereof.

Il s'agit par exemple d'un ou plusieurs bourrelets longitudinaux 42, coextrudé(s) avec l'enrobage 18 au niveau de l'extension latérale 16 et préférentiellement réalisé(s) avec un matériau plus compressible que la matière de garnissage 8, par exemple avec une mousse ou une matière cellulaire appropriée. De tels inserts, en créant des zones privilégiées de compression, facilitent la pose par encastrement de l'ensemble du rail selon l'invention.This is for example one or more longitudinal beads 42, coextruded with the coating 18 at the lateral extension 16 and preferably made (s) with a more compressible material that the packing material 8, for example with a foam or a suitable cellular material. Such inserts, by creating preferred areas of compression, facilitate the installation of the entire assembly of the rail according to the invention.
