Description

APPUI D'UN PANNEAU DE SECTION DE VOIE DE TRANSPORT GUIDE  SUPPORT OF A GUIDE TRANSPORT ROAD SECTION PANEL
1. Domaine technique de l'invention 1. Technical field of the invention
L'invention concerne les voies sans ballast pour véhicules de transport guidés, tels que des véhicules ferroviaires ou pneumatiques. L'invention concerne plus particulièrement un appui pour les sections de voie de transport guidé permettant de former par un agencement successif d'une pluralité de sections une voie sans ballast, une section de voie et une voie sans ballast correspondantes.  The invention relates to non-ballast tracks for guided transport vehicles, such as railway or pneumatic vehicles. More particularly, the invention relates to a support for the guided transport path sections for forming, by a successive arrangement of a plurality of sections, a non-ballast track, a track section and a corresponding ballastless track.
2. Arrière-plan technologique  2. Technological background
Depuis la naissance des voies de chemin de fer, il est connu d'installer ces voies sur du ballast, c'est-à-dire sur un lit de pierres concassées ou de graviers. Le ballast permet de répartir sur la plateforme de la voie sous jacente les efforts transmis par les traverses sous l'action des charges roulantes. Le ballast permet ainsi de limiter le tassement de la plateforme. Le ballast permet enfin d'enchâsser les traverses pour limiter leurs déplacements et leurs déformations.  Since the birth of railroad tracks, it is known to install these tracks on ballast, that is to say on a bed of crushed stone or gravel. The ballast makes it possible to distribute on the platform of the underlying track the forces transmitted by the sleepers under the action of the rolling loads. The ballast thus makes it possible to limit the settlement of the platform. The ballast finally allows to embed sleepers to limit their movements and deformations.
Depuis plusieurs années, les projets de voie sans ballast se multiplient, notamment les voies sur dalles de béton. En effet, ces systèmes de voie présentent les avantages de minimiser les coûts de maintenance des voies et d'allonger leur durée de vie.  For several years, the projects of track without ballast multiply, in particular the tracks on slabs of concrete. Indeed, these track systems have the advantages of minimizing track maintenance costs and extending their service life.
Ces voies sans ballast comprennent généralement une couche de fondation en béton ou en asphalte sur laquelle vient prendre place une dalle en béton coulée en place ou préfabriquée et destinée à supporter et ancrer les rails de la voie.  These non-ballast tracks generally comprise a concrete or asphalt foundation layer on which a cast-in-place or prefabricated concrete slab is used to support and anchor the rails of the track.
L'une des difficultés rencontrées lors de la réalisation d'une telle voie sans ballast est la précision nécessaire lors de la pose des dalles en béton sur la couche de fondation sous-jacente car celle-ci détermine directement la géométrie de la voie. De plus, en cas de dévers nécessaire sur le tracé de la voie, il faut adapter le terrassement de la couche de fondation pour former le dévers préalablement à la mise en place des dalles de béton. Le réglage de l'entraxe peut également poser des problèmes techniques. Enfin, après réglage de la géométrie de la voie, il est nécessaire de sceller ou d'ancrer les dalles en béton afin que celles-ci soient immobilisées de manière permanente. One of the difficulties encountered when producing such a track without ballast is the precision required when laying the concrete slabs on the underlying subgrade because it directly determines the geometry of the track. In addition, in the event of a necessary overhang on the route of the track, it is necessary to adapt the earthwork of the foundation layer to form the cant prior to the placement of the concrete slabs. Adjusting the center distance can also cause technical problems. Finally, after adjusting the geometry of the track, it is necessary to seal or anchor the concrete slabs so that they are permanently immobilized.
Les inventeurs ont donc cherché à proposer un nouveau concept d'appui et de voie sans ballast qui résout au moins certains des inconvénients des voies sans ballast connues.  The inventors have therefore sought to propose a new concept of support and track without ballast which solves at least some of the disadvantages of known channels without ballast.

4. Exposé de l'invention  4. Presentation of the invention
Pour ce faire, l'invention concerne un appui d'un panneau de section de voie de transport guidé destinée à être fixée sur une plateforme de voie sans ballast, le panneau s'étendant suivant un axe longitudinal et l'appui comprenant :  To do this, the invention relates to a support of a guided transport section section panel intended to be fixed on a track platform without ballast, the panel extending along a longitudinal axis and the support comprising:
- au moins un plot de fixation apte à être fixé à la plateforme,  at least one fixing stud adapted to be fixed to the platform,
au moins un berceau apte à soutenir le panneau, et  at least one cradle adapted to support the panel, and
des moyens de déplacement vertical dudit berceau par rapport audit plot de manière à pouvoir régler la hauteur du panneau par rapport à ladite plateforme et de définir le devers de la section de voie,  means for vertically moving said cradle with respect to said pad so as to be able to adjust the height of the panel relative to said platform and to define the deviation of the track section,
le berceau étant monté mobile verticalement suivant un axe vertical perpendiculaire à l'axe longitudinal dans ledit plot. the cradle being mounted vertically movable along a vertical axis perpendicular to the longitudinal axis in said stud.
Ainsi, un tel appui est simple de conception et permet un gain économique et de temps dans la pose sur chantier. Par ailleurs, le fait que le berceau se déplace verticalement dans le plot permet de fournir un appui compact et de guider le berceau dans ses déplacements.  Thus, such support is simple design and allows economic gain and time in laying on site. Moreover, the fact that the cradle moves vertically in the stud makes it possible to provide a compact support and to guide the cradle in its movements.
En particulier, le panneau de section de voie s'étend horizontalement suivant l'axe longitudinal.  In particular, the lane section panel extends horizontally along the longitudinal axis.
Suivant une caractéristique de l'invention, le plot de fixation comprend au moins une paroi latérale reliée à un fond et s'étendant suivant l'axe vertical, ladite paroi latérale étant configurée pour guider le déplacement dudit berceau suivant l'axe vertical.  According to a feature of the invention, the fixing stud comprises at least one side wall connected to a bottom and extending along the vertical axis, said side wall being configured to guide the movement of said cradle along the vertical axis.
Suivant une autre caractéristique de l'invention, l'appui comporte plusieurs berceaux se déplaçant et étant guidés dans le même plot.  According to another characteristic of the invention, the support comprises several cradles moving and being guided in the same pad.
Selon encore une autre caractéristique de l'invention, lesdits moyens de déplacement vertical d'un berceau comprennent :  According to yet another characteristic of the invention, said means for vertical displacement of a cradle comprise:
une cale en coin montée mobile sensiblement suivant un axe transversal par rapport audit plot et portant ledit berceau, a wedge wedge mounted substantially movable along a transverse axis with respect to said pad and carrying said cradle,
des moyens de blocage horizontal, suivant l'axe transversal, dudit berceau par rapport audit plot de sorte qu'un déplacement horizontal de ladite cale entraîne un déplacement vertical dudit berceau, ladite cale et le berceau comportant des moyens complémentaires configurés de manière à guider le déplacement de la cale par rapport au berceau, et  horizontal locking means, along the transverse axis, of said cradle relative to said pad so that a horizontal displacement of said block causes a vertical displacement of said cradle, said block and the cradle having complementary means configured to guide the cradle; displacement of the hold relative to the cradle, and
des moyens de déplacement horizontal suivant l'axe transversal, de ladite cale dans ledit plot.  means for horizontal displacement along the transverse axis of said wedge in said stud.
Selon cette variante avantageuse, le déplacement vertical du berceau par rapport au plot est réalisé par un déplacement horizontal, suivant l'axe transversal, d'une cale en coin par rapport au plot, ladite cale portant ledit berceau, conjugué à un blocage horizontal du berceau.  According to this advantageous variant, the vertical displacement of the cradle relative to the stud is achieved by a horizontal displacement, along the transverse axis, of a wedge wedge relative to the stud, said wedge carrying said cradle, conjugated to a horizontal locking of the cradle.
Selon encore une autre caractéristique de l'invention, lesdits moyens de blocage horizontal dudit berceau par rapport au plot comprenant un insert fileté en prise dans ledit plot et s 'étendant horizontalement à travers le plot en appui contre ledit berceau.  According to yet another characteristic of the invention, said horizontal locking means of said cradle relative to the stud comprising a threaded insert engaged in said stud and extending horizontally through the stud bearing against said cradle.
Selon encore une autre caractéristique de l'invention, lesdits moyens de déplacement horizontal de la cale comprennent une vis de réglage en appui contre ladite cale en coin et en prise dans le plot en s 'étendant horizontalement à travers ledit plot.  According to yet another characteristic of the invention, said means for horizontal displacement of the wedge comprise a set screw bearing against said wedge wedge and engaged in the stud extending horizontally through said stud.
Selon cette variante, le blocage horizontal du berceau est réalisé par une vis de réglage en liaison dans un insert fileté en prise dans le plot et qui vient en appui contre le berceau pour empêcher tout déplacement horizontal.  According to this variant, the horizontal blocking of the cradle is achieved by an adjusting screw connected in a threaded insert engaged in the stud and which bears against the cradle to prevent any horizontal movement.
En outre, le berceau étant bloqué horizontalement contre le plot, un déplacement horizontal de la cale en coin entraîne le glissement des plans inclinés l'un sur l'autre, qui se traduit par un déplacement vertical du berceau, son déplacement horizontal étant contraint par les moyens de blocage.  In addition, the cradle being blocked horizontally against the pad, a horizontal displacement of the wedge wedge causes the sliding of the inclined planes one on the other, which results in a vertical displacement of the cradle, its horizontal displacement being constrained by the blocking means.
Avantageusement, chaque appui comprend des moyens de déplacement horizontal de ladite cale en coin dans ledit plot.  Advantageously, each support comprises means for horizontal displacement of said wedge wedge in said stud.
Selon encore une autre caractéristique de l'invention, le berceau comprend au moins deux plans inclinés inférieurs complémentaires avec deux plans inclinés supérieurs de la cale, les deux plans inclinés inférieurs étant orientés suivant des directions sensiblement opposées. Les deux plans inclinés complémentaires forment une liaison glissière entre la cale et le berceau. Ces plans permettent également que le berceau soit en contact continu avec la cale. According to yet another characteristic of the invention, the cradle comprises at least two complementary lower inclined planes with two inclined planes upper wedges, the two lower inclined planes being oriented in substantially opposite directions. The two complementary inclined planes form a sliding connection between the hold and the cradle. These planes also allow the cradle to be in continuous contact with the hold.
Selon encore une autre caractéristique de l'invention, le fond du plot comporte au moins un premier plan incliné supérieur sur lequel est monté ladite cale, le premier plan incliné supérieur étant complémentaire avec un plan incliné inférieur de la cale. De la sorte, en l'absence d'une force d'appui par exemple de ladite vis de réglage sur ladite cale, ladite cale glisse sur ledit plan incliné dudit plot. Ainsi, selon cette variante, la vis de réglage vient en butée contre la cale en coin pour la pousser et ainsi assurer un déplacement vertical vers le haut du berceau de support. En cas de rétractation de la vis de réglage, la cale en coin vient spontanément par gravité glisser sur le plan incliné du plot, ce qui entraine un déplacement vertical vers le bas du berceau de support.  According to yet another characteristic of the invention, the bottom of the stud comprises at least a first upper inclined plane on which said shim is mounted, the first upper inclined plane being complementary with a lower inclined plane of the shim. In this way, in the absence of a bearing force for example of said adjusting screw on said wedge, said wedge slides on said inclined plane of said stud. Thus, according to this variant, the adjusting screw abuts against the wedge wedge to push and thus ensure a vertical upward movement of the support cradle. In case of retraction of the adjusting screw, the corner wedge spontaneously comes by gravity slide on the inclined plane of the stud, which causes a vertical downward movement of the support cradle.
Selon une autre variante, une extrémité de la vis de réglage est solidaire de la cale en coin de sorte qu'un déplacement de la vis par rapport au plot entraine, selon le sens de rotation imprimé à la vis, un déplacement vers le haut ou vers le bas du berceau de support porté par la cale en coin.  According to another variant, one end of the adjusting screw is integral with the wedge wedge so that a displacement of the screw relative to the stud causes, in the direction of rotation printed on the screw, an upward movement or down the support cradle carried by the wedge wedge.
De manière avantageuse, mais non limitativement, le premier plan incliné supérieur du fond forme avec l'axe transversal un angle compris entre 10° et 20°.  Advantageously, but not exclusively, the first upper inclined plane of the bottom forms with the transverse axis an angle of between 10 ° and 20 °.
De manière avantageuse, mais non limitativement, le premier plan incliné supérieur du fond forme avec l'axe longitudinal un angle compris entre 5° et 15°.  Advantageously, but not exclusively, the first upper inclined plane of the bottom forms with the longitudinal axis an angle of between 5 ° and 15 °.
Selon encore une autre caractéristique de l'invention, les plans inclinés inférieurs du berceau forment chacun avec l'axe longitudinal un angle compris entre 10° et 20°.  According to yet another characteristic of the invention, the lower inclined planes of the cradle each form, with the longitudinal axis, an angle of between 10 ° and 20 °.
Suivant une caractéristique de l'invention, le plot comprend deux parois latérales reliées audit fond, ledit fond comprenant un plan central incliné supérieur par rapport à l'axe transversal entre les parois latérales, le premier plan incliné supérieur du fond étant agencé entre une des parois latérales et le plan central incliné supérieur de manière à former une cuvette. De la sorte, la cuvette permet de garantir la stabilité de la cale logée dans cette cuvette et il n'y a pas d'effort susceptible de la faire sortir de son logement. According to a characteristic of the invention, the stud comprises two lateral walls connected to said bottom, said bottom comprising a central plane inclined higher with respect to the transverse axis between the side walls, the first upper inclined plane of the bottom being arranged between one of the side walls and the upper inclined central plane so as to form a bowl. In this way, the bowl makes it possible to guarantee the stability of the hold housed in this bowl and there is no effort likely to get her out of her home.
Selon encore une autre caractéristique de l'invention, au moins une des parois latérales comprend au moins un orifice traversant d'axe parallèle à l'axe longitudinal et apte à recevoir des moyens de désengagement de la cale de la cuvette. Une telle configuration est simple de conception et permet l'insertion aisée de ces moyens de désengagement.  According to yet another feature of the invention, at least one of the side walls comprises at least one through orifice of axis parallel to the longitudinal axis and adapted to receive means for disengaging the wedge from the bowl. Such a configuration is simple in design and allows the easy insertion of these disengagement means.
L'invention pourrait également concerner un appui d'un panneau de section de voie de transport guidé destinée à être fixée sur une plateforme de voie sans ballast, l'appui comprenant :  The invention could also relate to a support of a guided transport section section panel intended to be fixed on a track platform without ballast, the support comprising:
- au moins un plot de fixation apte à être fixé à la plateforme,  at least one fixing stud adapted to be fixed to the platform,
- au moins un berceau apte à soutenir le panneau, et  at least one cradle able to support the panel, and

L'invention concerne encore une section de voie de transport guidé destinée à être fixée sur une plateforme de voie sans ballast, la section de voie comprenant un panneau de voie comportant :  The invention further relates to a guided transport path section for attachment to a track platform without ballast, the track section comprising a track panel comprising:
- deux longrines s 'étendant le long d'un axe longitudinal, chaque longrine comprenant en outre une rainure longitudinale supérieure de réception d'un élément de roulement et/ou de guidage d'un véhicule de transport guidé, tel qu'un rail, et  - Two longitudinal members extending along a longitudinal axis, each sill further comprising an upper longitudinal groove for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail, and
au moins une structure solidaire desdites longrines et s 'étendant transversalement entre elles,  at least one structure integral with said longitudinal members and extending transversely between them,
la section de voie comprenant une pluralité d'appuis du panneau selon l'une quelconque des caractéristiques susmentionnées, adaptés pour être fixés à ladite plateforme de voie et configurés pour pouvoir supporter ledit panneau au-dessus de ladite plateforme de voie de manière à pouvoir régler la hauteur du panneau par rapport à ladite plateforme et de définir le devers de la section de voie ainsi formée par un réglage coordonné des différents berceaux. the track section comprising a plurality of panel supports according to one any of the aforesaid characteristics, adapted to be attached to said track platform and configured to support said panel above said track platform so as to adjust the height of the panel relative to said platform and to define the back of the track. track section thus formed by a coordinated setting of the different cradles.
Une section de voie selon l'invention permet donc de régler la géométrie précise de la voie postérieurement à l'installation de la voie sur la plateforme de la voie. En particulier, la hauteur de chaque longrine (et par conséquent, la hauteur de chaque élément de guidage et/ou de roulement logé dans la rainure de la longrine, désigné ci-après par le terme « rail » pour plus de simplicité) peut être ajustée, postérieurement à son installation. Cette hauteur de la longrine (c'est-à- dire la distance qui sépare la plateforme de la longrine) est définie et réglée par un déplacement du berceau de support d'une longrine. Ce déplacement du berceau est obtenu par la mise en œuvre des moyens de déplacement vertical du berceau.  A section of lane according to the invention thus makes it possible to adjust the precise geometry of the lane after the installation of the lane on the platform of the lane. In particular, the height of each sill (and therefore the height of each guide element and / or bearing housed in the groove of the sill, hereinafter referred to as "rail" for simplicity) can be adjusted, after installation. This height of the sill (that is to say the distance that separates the platform from the sill) is defined and adjusted by a displacement of the support cradle of a sill. This displacement of the cradle is obtained by the implementation of the means of vertical displacement of the cradle.
Dans tout le texte, on définit par « plateforme » de la voie, un terrain aménagé sur lequel la section de voie selon l'invention est destinée à être fixée. La plateforme de voie correspond au terrassement de la voie sur lequel on vient directement fixer les plots de la section de voie. Selon l'invention, cette plateforme est dénuée de tout ballast.  Throughout the text, the term "platform" of the track defines a landscaped ground on which the track section according to the invention is intended to be fixed. The track platform corresponds to the terracing of the track on which the studs of the track section are directly fixed. According to the invention, this platform is devoid of any ballast.
En outre, chaque longrine étant supportée par au moins un appui - de préférence deux appuis par longrine - un réglage coordonné des berceaux des différents appuis permet de former un dévers. Pour ce faire, les appuis d'une longrine sont réglés à une hauteur différente des appuis de l'autre longrine, ce qui permet de faire pivoter le panneau de voie autour d'un axe de direction longitudinale, formant ainsi le devers. Selon une variante avantageuse, la section de voie est configurée pour permettre le pivotement du panneau autour d'un axe longitudinal dont la position est confondue avec la table de roulement du rail supporté par la longrine dont la hauteur est restée fixe, formant ainsi le dévers. Selon l'invention, une section de voie ne nécessite pas de former un dévers directement sur le terrassement de la voie préalablement à l'installation de la voie. Ce devers peut être formé postérieurement à l'installation, par une inclinaison du panneau de voie, ce qui facilite les opérations de pose de la voie. In addition, each sill being supported by at least one support - preferably two sill supports - a coordinated setting of the cradles of the different supports allows to form a cant. To do this, the supports of a sill are adjusted to a different height of the supports of the other sill, which allows to rotate the track panel around a longitudinal direction axis, thus forming the back. According to an advantageous variant, the track section is configured to allow the pivoting of the panel about a longitudinal axis whose position is coincident with the tread of the rail supported by the sill whose height has remained fixed, thus forming the slope . According to the invention, a section of track does not require forming a cant directly on the earthwork of the track prior to the installation of the track. This devers can be formed after the installation, by an inclination of track panel, which facilitates the laying of the track.
En outre, une section de voie selon l'invention permet une compensation des tassements différentiels de la plateforme de la voie par un réglage individuel de chaque plot. La fonctionnalité de réglage de la section de voie selon l'invention permet également un réglage et une correction de la géométrie de la voie au cours de sa vie. La précision du terrassement est également moins critique qu'avec des voies de l'art antérieur de par la possibilité de pouvoir affiner ultérieurement la hauteur de chaque longrine par rapport à la plateforme et de rattraper d'éventuels défauts de terrassement.  In addition, a track section according to the invention allows compensation differential settlements of the platform of the track by an individual adjustment of each stud. The adjustment function of the track section according to the invention also allows adjustment and correction of the geometry of the track during its lifetime. The accuracy of the earthworks is also less critical than with prior art tracks by the possibility of being able to refine the height of each sill with respect to the platform and to make up for any earthworks defects.
Une section de voie selon l'invention est directement fixée sur la plateforme de la voie et ne nécessite pas le coulage d'une dalle de béton ou d'asphalte. Aussi, la réalisation d'une voie de transport mettant en œuvre des sections de voie selon l'invention est réalisée plus rapidement qu'avec les techniques de voie sans ballast de l'art antérieur.  A section of track according to the invention is directly attached to the platform of the track and does not require the pouring of a slab of concrete or asphalt. Also, the realization of a transport path implementing sections of track according to the invention is performed more quickly than with the prior art ballastless track techniques.
De plus, la voie s'étend au-dessus de la plateforme, ce qui permet de laisser passer l'eau sous le panneau de voie en cas d'inondation de la plateforme.  In addition, the track extends above the platform, allowing water to pass under the lane sign in case of flooding of the platform.
Chaque longrine d'un panneau de voie d'une section selon l'invention comprend une rainure longitudinale supérieure de réception d'un élément de roulement et/ou de guidage d'un véhicule de transport guidé, tel qu'un rail et son système de fixation associé. La section peut donc être utilisée avec différents types de véhicule, dont le type est défini lors de la pose de l'élément de roulement et/ou de guidage.  Each liner of a lane panel of a section according to the invention comprises an upper longitudinal groove for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail and its system. associated fixation. The section can therefore be used with different types of vehicle, the type of which is defined during the installation of the rolling element and / or guide.
Dans toute la suite et par mesure de simplicité, le terme « rail » est utilisé de manière générique pour définir les éléments de roulement et les éléments de guidage qui peuvent être logés dans les rainures de chaque longrine, étant entendu qu'il s'agit d'un rail en tant que tel pour un véhicule ferroviaire, mais d'une piste de roulement pour un véhicule pneumatique.  In all the following and for the sake of simplicity, the term "rail" is used generically to define the rolling elements and guide elements that can be housed in the grooves of each sill, it being understood that this is a rail as such for a rail vehicle, but a running track for a pneumatic vehicle.
Une section selon l'invention comprend un berceau monté mobile verticalement dans le plot et des moyens de déplacement vertical de ce berceau par rapport au plot.  A section according to the invention comprises a cradle mounted vertically movable in the stud and vertical displacement means of this cradle relative to the stud.
Suivant un mode de réalisation de l'invention, la structure comprend au moins deux traverses solidaires des longrines. En particulier, lesdites traverses sont des tubes d'acier. According to one embodiment of the invention, the structure comprises minus two ties integral with the stringers. In particular, said sleepers are steel tubes.
Suivant un autre mode de réalisation de l'invention, la structure comprend au moins une dalle solidaire des longrines. Cette dalle peut être avantageusement réalisée en béton.  According to another embodiment of the invention, the structure comprises at least one slab secured to the longitudinal members. This slab can be advantageously made of concrete.
De manière avantageuse, mais non limitativement, la dalle comprend une nervure centrale longitudinalement ménagée entre les deux longrines. Cette nervure permet de renforcer structurellement la dalle et permet également d'éviter le déraillement du véhicule guidé. Le véhicule restera toujours sur le panneau.  Advantageously, but not exclusively, the slab comprises a longitudinal central rib formed between the two longitudinal struts. This rib reinforces structurally the slab and also avoids the derailment of the guided vehicle. The vehicle will always remain on the panel.
Suivant encore une autre caractéristique, le berceau comprend une face supérieure arrondie.  According to yet another characteristic, the cradle comprises a rounded upper face.
De manière avantageuse, mais non limitativement, la face supérieure est revêtue d'une semelle élastique.  Advantageously, but not exclusively, the upper face is coated with an elastic sole.
De manière avantageuse, chaque longrine présente une face inférieure arrondie conformée à la face supérieure arrondie du berceau. Cette face arrondie est avantageusement cylindrique, au sens mathématique du terme, c'est-à-dire qu'elle présente une surface définie par le déplacement d'une droite parallèlement à elle-même sur une génératrice, qui en l'occurrence est un demi-cercle.  Advantageously, each sill has a rounded lower face shaped to the rounded upper face of the cradle. This rounded face is advantageously cylindrical, in the mathematical sense of the term, that is to say that it has a surface defined by the displacement of a line parallel to itself on a generator, which in this case is a Semi circle.
Selon cette variante, le berceau et la longrine présentent des formes complémentaires de telle sorte que le berceau enserre la longrine et forme avec elle une zone de contact continu de support. La forme arrondie permet également d'éviter tout déplacement transversal de la longrine lorsqu'elle est montée et supportée par les berceaux. En effet, les parois latérales du berceau forment alors des butées transversales.  According to this variant, the cradle and the sill have complementary shapes such that the cradle encloses the sill and forms with it a continuous contact area of support. The rounded shape also prevents transverse movement of the sill when mounted and supported by the cradles. Indeed, the side walls of the cradle then form transverse stops.
Avantageusement et selon l'invention, chaque longrine comprend en outre deux butées ménagées transversalement sur une face inférieure de la longrine et configurées pour pouvoir recevoir entre elles un berceau de sorte qu'il puisse, une fois logé entre les deux butées, bloquer longitudinalement chaque longrine.  Advantageously and according to the invention, each sill further comprises two stops arranged transversely on a lower face of the sill and configured to be able to receive between them a cradle so that it can, once housed between the two stops, lock longitudinally each sill.
Les butées ménagées transversalement sous chaque longrine permettent d'empêcher tout glissement longitudinal de la longrine par rapport audit berceau.  The stops arranged transversely under each sill prevent longitudinal slippage of the sill relative to said cradle.
Avantageusement, mais non limitativement, la section de voie comprend au moins deux appuis par panneau. Avantageusement, la section de voie comprend quatre appuis par panneau. Advantageously, but not exclusively, the track section comprises at least two supports per panel. Advantageously, the track section comprises four supports per panel.
Suivant un autre mode de réalisation, la section de voie selon l'invention comprend deux appuis par longrine.  According to another embodiment, the track section according to the invention comprises two sill supports.
Suivant une caractéristique de l'invention, lesdites longrines et lesdits appuis sont formés en béton.  According to a feature of the invention, said longitudinal members and said supports are formed of concrete.
Suivant une autre caractéristique de l'invention, ledit plot de fixation est monté sur un massif métallique comprenant une plaque métallique et une pluralité d'éléments d'implantation soudés sous la plaque métallique et s'étendant suivant l'axe vertical perpendiculaire à la plaque, ledit massif métallique étant destiné à être inséré dans ladite plateforme de voie par battage ou fonçage pour fixer cet appui.  According to another characteristic of the invention, said fixing stud is mounted on a metal block comprising a metal plate and a plurality of implantation elements welded under the metal plate and extending along the vertical axis perpendicular to the plate. , said metal block being intended to be inserted into said track platform by threshing or driving to fix this support.
Un tel massif métallique comprend par exemple plusieurs (seize dans un cas particulier) éléments d'implantation soudés sur la plaque métallique solidarisée de la partie inférieure du plot de fixation.  Such a metal solid comprises for example several (sixteen in a particular case) implantation elements welded to the metal plate secured to the lower part of the fixing stud.
Selon une caractéristique de l'invention, les éléments d'implantation comprennent des profilés de section en forme de H. Une telle caractéristique permet de mieux supporter le battage pour enfoncer ces éléments d'implantation dans la plateforme.  According to one characteristic of the invention, the implantation elements comprise section sections in the form of an H. Such a characteristic makes it possible to better withstand threshing in order to drive these implantation elements into the platform.
Suivant un autre mode de réalisation, les éléments d'implantation comprennent un pluralité de tubes d'acier.  According to another embodiment, the implantation elements comprise a plurality of steel tubes.
La solidarisation du plot de fixation au massif métallique peut être de tous types. Par exemple, le plot de fixation est collé sur la plaque métallique, ou boulonné sur la plaque métallique.  The fastening of the fastening stud to the metal solid can be of any type. For example, the mounting pad is glued to the metal plate, or bolted to the metal plate.
Selon une autre variante, le plot est fixé à la plateforme par des micropieux, par exemple par trois micro-pieux. Ces micro-pieux peuvent être foncés, battus ou forés dans la plateforme de la voie.  According to another variant, the stud is fixed to the platform by micropiles, for example by three micro-piles. These micro-piles can be dark, beaten or drilled in the platform of the track.
Suivant une autre caractéristique de l'invention, le massif comprend des moyens de calage du plot agencés sur la plaque métallique.  According to another characteristic of the invention, the solid mass comprises pad setting means arranged on the metal plate.

La figure 1 représente uniquement deux sections 16, 17 successives. Néanmoins, il va de soi qu'en pratique, une voie ou un tronçon de voie comprend une multitude de sections de voie agencées successivement sur un terrassement (ou une plateforme 15). Sur la figure 2 est illustrée une portion d'une section de voie 16' selon un deuxième mode de réalisation de l'invention. As shown in FIG. 1, a track 1 without a ballast according to the invention intended to allow the transport of a guided vehicle, such as a rail or pneumatic vehicle, comprises a track platform 15 without ballast and a plurality of sections. , 17 of lane according to a first embodiment of the invention fixed successively on the platform 15. FIG. only two sections 16, 17 successive. Nevertheless, it goes without saying that in practice, a track or a section of track comprises a multitude of sections of track successively arranged on an earthwork (or platform 15). In Figure 2 is illustrated a portion of a channel section 16 'according to a second embodiment of the invention.
Dans toute la suite de la description, une section de voie va être décrite en détail en référence à la section 16, 16' de voie, entendu que les autres sections de voie peuvent être identiques.  Throughout the rest of the description, a section of track will be described in detail with reference to section 16, 16 'of track, understood that the other track sections may be identical.
Tel que représenté sur la figure 3, la section 16 de voie du premier mode de réalisation comprend un panneau 20 de voie et des appuis 31, 32, 33, 34 fixés sur la plateforme 15. Un appui 34 est représenté en perspective éclatée pour faire apparaître les différents éléments formant l'appui qui sont décrits en référence aux figures 13 et 14 ci-après.  As shown in FIG. 3, the track section 16 of the first embodiment comprises a track panel 20 and supports 31, 32, 33, 34 fixed to the platform 15. A support 34 is shown in exploded perspective to make appear the different elements forming the support which are described with reference to Figures 13 and 14 below.
Tel que représenté sur les figures 3 et 4, le panneau 20 de voie s'étend horizontalement suivant l'axe longitudinal L. le panneau 20 comprend deux longrines 21, 22 qui s'étendent le long de l'axe longitudinal, qui se confond à la direction de circulation des véhicules, une fois la voie installée. Le panneau 20 de voie comprend également une structure transversale s'étendant suivant l'axe transversal T. Cette structure transversale comprend dans ce premier mode de réalisation deux traverses 23, 24 qui s'étendent en particulier transversalement aux longrines 21, 22. Selon ce mode de réalisation, ces traverses 23, 24 sont formées par des tubes métalliques dont les extrémités sont solidarisées des longrines 21, 22. Ces longrines sont de préférence formées de béton. Un panneau 20 de voie selon ce mode de réalisation présente une forme générale d'échelle. Selon une variante non décrite, le panneau 20 de voie peut comprendre des traverses en béton et former d'autres formes qu'une échelle. Par exemple, les traverses peuvent être ménagées à chaque extrémité longitudinale des longrines.  As shown in Figures 3 and 4, the track panel 20 extends horizontally along the longitudinal axis L. The panel 20 comprises two longitudinal members 21, 22 which extend along the longitudinal axis, which merges to the traffic direction of vehicles, once the track is installed. The track panel 20 also comprises a transverse structure extending along the transverse axis T. This transverse structure comprises in this first embodiment two crosspieces 23, 24 which extend in particular transversely to the longitudinal members 21, 22. embodiment, these crosspieces 23, 24 are formed by metal tubes whose ends are secured to the longitudinal members 21, 22. These longitudinal members are preferably formed of concrete. A track panel 20 according to this embodiment has a general ladder shape. According to an undescribed variant, the track panel may comprise concrete sleepers and form other shapes than a ladder. For example, the cross members may be provided at each longitudinal end of the longitudinal members.
La longrine 21 va maintenant être décrite en détail, étant entendu que la longrine 22 présente une architecture identique. La longrine 21 comprend une rainure 25 longitudinale supérieure de réception d'un élément de roulement et/ou de guidage d'un véhicule de transport guidé, tel qu'un rail. Cette rainure 25 s'étend donc longitudinalement suivant l'axe longitudinal L et est configurée pour recevoir l'élément de guidage ou de roulement sur lequel le véhicule de transport va pouvoir circuler. Dans le cas d'un véhicule ferroviaire, l'élément de guidage est un rail 41. Cette rainure 25 est également destinée à recevoir les moyens de fixation du rail à la longrine. La longrine 21 comprend également, selon un mode préférentiel de réalisation, une nervure formant un muret 26 s 'étendant longitudinalement au niveau du bord latéral de la longrine 21. Ce muret 26 permet de bloquer latéralement un véhicule en cas de déraillement. Ce muret 26 est donc un organe de sécurité de la voie. Ce muret 26 fait également office de dispositif antibruit en bloquant la propagation des ondes sonores émises du fait des interactions du véhicule et du rail. Chaque longrine comprend également, suivant ce mode de réalisation, deux butées 27, 28 transversales ménagées sur la surface inférieure de la longrine comme cela est visible sur la figure 5. Ces butées 27, 28 sont espacées longitudinalement l'une de l'autre d'une distance sensiblement égale à la dimension longitudinale d'un berceau d'un appui (décrit ci-après en lien avec les figures 13 et 14) de telle sorte qu'une fois le berceau logé entre les deux butées, il assure un blocage longitudinal, suivant l'axe longitudinal L, de la longrine 21 et donc, un blocage du panneau 20 de voie correspondant. La longrine présente dans cet exemple de réalisation, une face inférieure 47 arrondie. Chaque appui 31, 32, 33, 34 est adapté pour être fixé à la plateforme 15 de voie et configuré pour pouvoir supporter une partie d'au moins une longrine. The sill 21 will now be described in detail, it being understood that the sill 22 has an identical architecture. The sill 21 comprises an upper longitudinal groove 25 for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail. This groove 25 therefore extends longitudinally along the longitudinal axis L and is configured to receive the guide element or bearing on which the transport vehicle will be able to circulate. In the case of a railway vehicle, the guide element is a rail 41. This groove 25 is also intended to receive the rail fastening means to the sill. The sill 21 also comprises, according to a preferred embodiment, a rib forming a wall 26 extending longitudinally at the lateral edge of the sill 21. This wall 26 can laterally block a vehicle in case of derailment. This wall 26 is therefore a safety member of the track. This wall 26 also serves as a noise-canceling device by blocking the propagation of sound waves emitted due to the interactions of the vehicle and the rail. Each sill also comprises, according to this embodiment, two stops 27, 28 transverse formed on the lower surface of the sill as can be seen in Figure 5. These stops 27, 28 are spaced longitudinally from each other. a distance substantially equal to the longitudinal dimension of a cradle of a support (described hereinafter with reference to FIGS. 13 and 14) so that once the cradle is housed between the two abutments, it ensures a blocking longitudinal, along the longitudinal axis L, of the sill 21 and therefore a blocking of the corresponding channel panel 20. The sill presents in this embodiment, a lower face 47 rounded. Each support 31, 32, 33, 34 is adapted to be fixed to the platform 15 and configured to be able to support a portion of at least one sill.
Suivant le deuxième de réalisation illustré sur les figures 2 et 6 à 9, la section 16' de voie comprend un panneau de voie 20 et des appuis. Le panneau 20 comprend également deux longrines 21, 22 s 'étendant suivant l'axe longitudinal L. Ces longrines comprennent également chacune une rainure 25 longitudinale supérieure de réception d'un élément de roulement et/ou de guidage d'un véhicule de transport guidé. Suivant ce mode de réalisation, la rainure 25 s'étend suivant l'axe longitudinal mais de manière discontinue. La structure transversale du panneau 20 comprend une dalle 29 s'étendant transversalement entre les deux longrines 21, 22. En particulier, la dalle 29 est solidaire des longrines. Cette dalle 29 est définie dans un plan perpendiculaire à l'axe vertical V. La dalle 29 comprend une nervure centrale 30 ménagée entre les deux longrines par rapport à l'axe transversal T de manière à renforcer structurellement la dalle 29. Celle-ci forme également des moyens anti-déraillement du véhicule guidé. La nervure centrale 30 s'étend suivant l'axe L. En particulier, celle-ci est prévue en partie supérieure de la dalle 29. Suivant une variante de réalisation illustrée sur la figure 9, la nervure centrale 30 est réalisée en partie inférieure de la dalle 29. La dalle est réalisée avantageusement en béton. Chaque appui est adapté pour être fixé à la plateforme 15 de voie et configuré pour pouvoir supporter une partie d'au moins une longrine. According to the second embodiment illustrated in Figures 2 and 6 to 9, the section 16 'of track comprises a track panel 20 and supports. The panel 20 also comprises two longitudinal members 21, 22 extending along the longitudinal axis L. These longitudinal members also each comprise an upper longitudinal groove 25 for receiving a rolling element and / or guiding a guided transport vehicle . According to this embodiment, the groove 25 extends along the longitudinal axis but in a discontinuous manner. The transverse structure of the panel 20 comprises a slab 29 extending transversely between the two longitudinal members 21, 22. In particular, the slab 29 is integral with the longitudinal members. This slab 29 is defined in a plane perpendicular to the vertical axis V. The slab 29 comprises a central rib 30 formed between the two longitudinal members relative to the transverse axis T so as to structurally strengthen the slab 29. It also forms anti-derailment means of the guided vehicle. The central rib 30 extends along the axis L. In particular, it is provided in the upper part of the slab 29. According to an alternative embodiment illustrated in Figure 9, the central rib 30 is made in the lower part of the slab 29. The slab is advantageously made of concrete. Each support is adapted to be attached to the track platform and configured to support a portion of at least one sill.
On va maintenant décrire les appuis en détail étant entendu que les appuis présentent une architecture sensiblement identique. Chaque appui comprend au moins un plot de fixation apte à être fixé à la plateforme, au moins un berceau apte à soutenir le panneau, et des moyens de déplacement vertical dudit berceau par rapport audit plot de manière à pouvoir régler la hauteur du panneau par rapport à ladite plateforme et de définir le devers de la section de voie.  We will now describe the supports in detail, it being understood that the supports have a substantially identical architecture. Each support comprises at least one attachment pad adapted to be fixed to the platform, at least one cradle adapted to support the panel, and means for vertically moving said cradle relative to said block so as to adjust the height of the panel relative to to said platform and to define the devers of the lane section.
En référence aux figures 1, 3, 13 à 16 et 22, l'appui 34, selon le premier mode de réalisation, comprend un plot 35 de fixation à la plateforme 15. Ce plot 35 de fixation comprend une forme généralement cylindrique. En particulier, le plot 35 comprend une base 35a destinée à reposer sur la plateforme 15, des parois latérales 35b, une paroi arrière 35c, et un fond 35d. Les parois latérales 35b, la paroi arrière 35c et le fond 35a, forment un logement de réception des autres organes de l'appui 35. En particulier, les parois latérales 35b ainsi que la paroi arrière 35c s'étendent suivant l'axe vertical V. Les parois latérales 35b sont reliées au fond 35d. Celles-ci sont également reliées à la paroi arrière 35c. Les autres organes de l'appui comprennent une cale 36 en coin qui repose sur le fond 35d du plot 35, et un berceau 37 de soutien de la longrine 22 qui repose sur la cale 36. Comme cela est visible notamment sur les figures 13 et 14, le coin 36 et le berceau 37 sont installés entre les deux parois latérales 35b du plot 35. En outre, l'appui comprend une vis 38 de réglage et une vis 39 de blocage horizontal du berceau 37. Chaque vis s'étend à travers la paroi arrière 35c du plot par un trou taraudé 53 formé dans la paroi arrière 35c. Ce trou taraudé 53 présente ici un axe parallèle à l'axe transversal T. Chaque trou taraudé présente un filetage conjugué au filetage de la vis qu'il reçoit de manière à ce que la vis soit en prise dans la paroi arrière et qu'une rotation de cette vis dans ce trou taraudé entraîne un déplacement horizontal, ici suivant l'axe transversal T, de cette vis par rapport au plot 35. La cale 36 présente en outre un plan supérieur incliné conjugué à un plan inférieur incliné du berceau 37. La cale 36 présente également, selon le mode de réalisation des figures 13 et 14 un plan inférieur incliné P6 conjugué à un plan supérieur incliné du fond 35d du plot 35 (cf. figure 14). With reference to FIGS. 1, 3, 13 to 16 and 22, the support 34, according to the first embodiment, comprises a stud 35 for fixing to the platform 15. This fixing stud 35 comprises a generally cylindrical shape. In particular, the stud 35 comprises a base 35a intended to rest on the platform 15, side walls 35b, a rear wall 35c, and a bottom 35d. The side walls 35b, the rear wall 35c and the bottom 35a form a housing for receiving the other members of the support 35. In particular, the side walls 35b and the rear wall 35c extend along the vertical axis V The side walls 35b are connected to the bottom 35d. These are also connected to the rear wall 35c. The other members of the support comprise a wedge 36 wedge which rests on the bottom 35d of the stud 35, and a cradle 37 for supporting the sill 22 which rests on the wedge 36. As can be seen in particular in FIGS. 14, the wedge 36 and the cradle 37 are installed between the two side walls 35b of the stud 35. In addition, the support comprises a screw 38 for adjusting and a horizontal locking screw 39 of the cradle 37. Each screw extends to through the rear wall 35c of the stud by a threaded hole 53 formed in the rear wall 35c. This tapped hole 53 here has an axis parallel to the transverse axis T. Each tapped hole has a thread conjugate to the thread of the screw that it receives so that the screw is engaged in the rear wall and a rotation of this screw in this threaded hole causes a horizontal displacement, here along the transverse axis T, of this screw relative to the stud 35. The wedge 36 further has an inclined upper plane conjugated to a lower inclined plane of the cradle 37. The wedge 36 also has, according to the embodiment of FIGS. 13 and 14, an inclined lower plane P6 conjugated to an inclined upper plane of the bottom 35d of the stud 35 (see FIG.
Ainsi, une rotation de la vis 38 de réglage par un opérateur entraîne un déplacement de la cale 36 sur le fond 35d du plot 35. Ce déplacement de la cale en coin 36 entraîne un glissement l'un sur l'autre des plans inclinés de la cale en coin 36 et du berceau 37. Le berceau 37 étant bloqué horizontalement par la vis de blocage 39, le berceau 37 est spontanément entraîné en déplacement vertical dans le plot 35. En d'autres termes, une rotation de la vis 38 de réglage permet de faire monter ou descendre le berceau 37 dans le plot 35 et par conséquent permet de régler la hauteur de la longrine portée par cet appui. Plus précisément encore, les parois latérales 35b du plot permettent de guider le déplacement vertical du berceau dans le plot. Nous entendons ainsi par l'expression le montage ou déplacement du berceau « dans le plot » le fait que le berceau est disposé et logé à l'intérieur du plot 35 et qu'il soit guidé à l'intérieur du plot. L'appui est ainsi compact et le plot permet de guider le berceau dans ses déplacements.  Thus, a rotation of the adjusting screw 38 by an operator causes a displacement of the shim 36 on the bottom 35d of the stud 35. This displacement of the wedge wedge 36 causes a sliding on one another of the inclined planes of the wedge 36 and the cradle 37. The cradle 37 being blocked horizontally by the locking screw 39, the cradle 37 is spontaneously driven in vertical displacement in the stud 35. In other words, a rotation of the screw 38 of adjustment makes it possible to raise or lower the cradle 37 in the stud 35 and consequently makes it possible to adjust the height of the sill carried by this support. More precisely still, the lateral walls 35b of the stud make it possible to guide the vertical displacement of the cradle in the stud. We thus mean by the expression the mounting or displacement of the cradle "in the stud" the fact that the cradle is disposed and housed inside the stud 35 and that it is guided inside the stud. The support is compact and the stud can guide the cradle in its movements.
Les figures 15 et 16 représentent un appui selon une autre variante. Selon cette variante de réalisation, le plot 35 présente un fond plat et les moyens de réglage de la hauteur sont formés d'une seule vis 38 qui est en prise dans la cale 36 pour pouvoir déplacer horizontalement la cale 36 dans un sens ou dans l'autre. Selon cette variante de réalisation, les moyens de blocage horizontal du berceau sont formés d'un tube 42 qui s'étend entre les parois latérales du plot 35.  Figures 15 and 16 show a support according to another variant. According to this embodiment, the stud 35 has a flat bottom and the height adjustment means are formed of a single screw 38 which is engaged in the shim 36 to be able to horizontally move the shim 36 in one direction or in the other. 'other. According to this variant embodiment, the means for horizontally locking the cradle are formed of a tube 42 which extends between the side walls of the stud 35.
En référence aux figures 2, 10 à 12, 16, 17, 22 et 23, l'appui 34' selon le deuxième mode de réalisation comprend également un plot 35 de fixation à la plateforme 15. Dans ce plot 35 sont montés plusieurs cales 36 et plusieurs berceaux 37. Le plot 35 s'étend ici suivant l'axe transversal longitudinal T. Dans ce plot 35 tel que représenté plus précisément sur la figure 10, sont montés quatre cales en coin 36 portant chacune respectivement un berceau 37. En d'autres termes, quatre berceaux 37 sont logés dans le plot 35. Dans ce cas de figures, ces quatre berceaux 37 sont agencés par paire. Chaque paire de berceaux 37 coopère par appui latéral et coulissement ou déplacement avec une même paroi latérale 35b du plot 35. Autrement dit, le berceau 37 est guidé dans son déplacement vertical par rapport une paroi latérale 35b. Le plot 35 comprend une saillie 40 s'étendant transversalement dans le plot 35 suivant l'axe transversal T. En particulier, la saillie 40 s'étend suivant l'axe longitudinal L. Celle-ci 40 est disposée sensiblement au niveau de la partie médiane suivant l'axe T. La saille 40 s'étend également suivant l'axe vertical depuis le fond 35a du plot 35. Bien entendu, le plot 35 peut être réalisé sans cette saillie 40. De part et d'autre de la saillie 40 sont montées deux cales 36 portant un berceau 37. Dans la suite de cette description est décrit l'agencement des cales et berceaux d'un côté de la saillie 40. Referring to Figures 2, 10 to 12, 16, 17, 22 and 23, the support 34 'according to the second embodiment also comprises a stud 35 for attachment to the platform 15. In this stud 35 are mounted several shims 36 and several cradles 37. The stud 35 extends here along the longitudinal transverse axis T. In this stud 35 as shown more precisely in FIG. 10, are mounted four wedges 36 each bearing respectively a cradle 37. In other words, four cradles 37 are housed in the stud 35. In this case of figures, these four cradles 37 are arranged in pairs. Each pair of cradles 37 cooperates by lateral support and sliding or displacement with the same side wall 35b of the pad 35. In other words, the cradle 37 is guided in its vertical displacement relative to a side wall 35b. The stud 35 comprises a projection 40 extending transversely in the stud 35 along the transverse axis T. In particular, the projection 40 extends along the longitudinal axis L. The latter 40 is disposed substantially at the level of the portion median along the axis T. The seam 40 also extends along the vertical axis from the bottom 35a of the stud 35. Of course, the stud 35 can be made without this projection 40. On either side of the protrusion 40 are mounted two shims 36 carrying a cradle 37. In the remainder of this description is described the arrangement of wedges and cradles on one side of the projection 40.
Le fond 35d du plot 35 comprend un premier plan incliné supérieur P5 sur lequel est montée une cale en coin 36. Le fond 35d comprend également un plan central incliné supérieur P7 par rapport à l'axe transversal longitudinal T. Ce plan central incliné supérieur P7 est agencé entre les parois latérales 35b du plot 35. En particulier, deux premiers plans inclinés supérieurs P5 sont disposés de part et d'autre de ce plan central incliné P7. Autrement dit, le premier plan incliné supérieur P5 est agencé entre une paroi latérale 35b et le plan central incliné supérieur P7 de manière à former une cuvette 43. La cale 36 est ainsi logée dans cette cuvette 43. Il est formé dans ce plot 35 quatre cuvettes 40 logeant chacune une cale 36. Le premier plan incliné supérieur P5 est complémentaire avec le plan inférieur incliné P6 de la cale 36. Le premier plan incliné supérieur P5 forme avec l'axe transversal T un angle a compris entre 10° et 20° (cf. figure 11). Tandis que le plan central incliné supérieur P7 forme avec l'axe transversal T un angle compris 15° et 30°. Le premier plan incliné supérieur P5 du fond 35d forme également avec l'axe longitudinal L un angle γ compris entre 5° et 15° (cf. figure 12). Comme cela est visible sur les figures 11 et 12, les premiers plans inclinés supérieurs P5, P5' du fond 35d sont orientés suivant des directions opposées. Chaque premier plan P5, P5' du fond 35d est incliné en direction d'une extrémité inférieure d'une paroi latérale 35b adjacente. The bottom 35d of the stud 35 comprises a first upper inclined plane P5 on which is mounted a wedge wedge 36. The bottom 35d also comprises an upper inclined central plane P7 with respect to the longitudinal transverse axis T. This central plane inclined upper P7 is arranged between the side walls 35b of the stud 35. In particular, two first inclined top planes P5 are arranged on either side of this inclined central plane P7. In other words, the first upper inclined plane P5 is arranged between a side wall 35b and the upper inclined central plane P7 so as to form a bowl 43. The shim 36 is thus housed in this bowl 43. It is formed in this block four. cuvettes 40 each housing a shim 36. The first upper inclined plane P5 is complementary to the inclined lower plane P6 of the shim 36. The first upper inclined plane P5 forms with the transverse axis T an angle α of between 10 ° and 20 °. (see Figure 11). While the central plane inclined upper P7 forms with the transverse axis T an angle of 15 ° and 30 °. The first upper inclined plane P5 of the bottom 35d also forms with the longitudinal axis L an angle γ of between 5 ° and 15 ° (see FIG. As can be seen in FIGS. 11 and 12, the first upper inclined planes P5, P5 'of the bottom 35d are oriented in opposite directions. Each first plane P5, P5 'of the bottom 35d is inclined towards a lower end of an adjacent side wall 35b.
Chaque berceau 37 comprend deux plans inclinés inférieurs PI, P2 complémentaires avec deux plans inclinés supérieurs P3, P4 de la cale 36. Les deux plans inclinés inférieurs PI, P2 du berceau 37 sont orientés suivant des directions sensiblement opposées. De même pour la cale 36, les plans inclinés supérieurs P3, P4 sont orientés suivant des directions opposées. Cela permet de favoriser le déplacement du berceau 37 par rapport à la cale 36 et également de permettre un contact continu entre la cale 36 et le berceau 37. De manière avantageuse, les plans inclinés inférieurs PI, P2 du berceau 37 forment chacun avec l'axe longitudinal L un angle β compris entre 10° et 20°. Avantageusement, mais non limitativement, les plans inclinés P3, P4 de la cale 36 forment entre eux un V ouvert vers le haut, soit vers le berceau 37.  Each cradle 37 comprises two lower inclined planes PI, P2 complementary with two upper inclined planes P3, P4 of the shim 36. The two lower inclined planes PI, P2 of the cradle 37 are oriented in substantially opposite directions. Similarly for the shim 36, the upper inclined planes P3, P4 are oriented in opposite directions. This makes it possible to promote the displacement of the cradle 37 with respect to the shim 36 and also to allow continuous contact between the shim 36 and the cradle 37. Advantageously, the lower inclined planes P 1, P 2 of the cradle 37 each form with the longitudinal axis L an angle β between 10 ° and 20 °. Advantageously, but not exclusively, the inclined planes P3, P4 of the shim 36 form between them an open V upwards, or towards the cradle 37.
Chaque berceau 37 comprend également une face supérieure arrondie 48. Cette face supérieure 48 est adaptée à la forme arrondie de la face 47 de la longrine 22. De manière avantageuse, mais non limitativement, la face supérieure 48 est revêtue d'une semelle 49 de manière à amortir les éventuels déplacements verticaux du panneau de voie 20. Cette semelle 49 est réalisée dans un matériau polymère. Le matériau polymère est par exemple un élastomère.  Each cradle 37 also comprises a rounded upper face 48. This upper face 48 is adapted to the rounded shape of the face 47 of the sill 22. Advantageously, but not exclusively, the upper face 48 is coated with a sole 49 of so as to dampen any vertical displacements of the track panel 20. This sole 49 is made of a polymeric material. The polymeric material is, for example, an elastomer.
Dans ce mode de réalisation, le trou taraudé 53 destiné à recevoir la vis de blocage 39 est réalisé dans la paroi de la saillie 40. Le trou taraudé 53 s'étend suivant l'axe transversal T. La vis de blocage 39 du berceau 37 s'étend à travers le plot 35 suivant l'axe transversal T. La paroi arrière 35c du fond comprend le trou taraudé 53' destiné à recevoir la vis 38 de réglage permettant de faire monter ou descendre le berceau 37 dans le plot 35.  In this embodiment, the tapped hole 53 for receiving the locking screw 39 is formed in the wall of the projection 40. The tapped hole 53 extends along the transverse axis T. The locking screw 39 of the cradle 37 extends through the stud 35 along the transverse axis T. The rear wall 35c of the bottom comprises the tapped hole 53 'intended to receive the adjusting screw 38 for raising or lowering the cradle 37 in the stud 35.
Ainsi, une rotation d'une vis 38 de réglage par un opérateur entraîne un déplacement de la cale 36 correspondante sur le fond 35d du plot 35. Ce déplacement de la cale 36 entraîne un glissement l'un sur l'autre des plans inclinés PI, P2, P3, P4 de la cale en coin 36 et du berceau 37 porté par cette cale. Le berceau 37 étant bloqué horizontalement par la vis de blocage 39, le berceau 37 est spontanément entraîné en déplacement vertical dans le plot 35. Chaque paroi latérale 35b du plot permet de guider le déplacement vertical du berceau dans le plot. L'appui est ainsi compact et le plot permet de guider les berceaux dans leurs déplacements. Thus, a rotation of an adjustment screw 38 by an operator causes a displacement of the corresponding shim 36 on the bottom 35d of the stud 35. This displacement of the wedge 36 causes a sliding on one another of the inclined planes PI , P2, P3, P4 of wedge wedge 36 and cradle 37 carried by this wedge. The cradle 37 being blocked horizontally by the locking screw 39, the cradle 37 is spontaneously driven vertically in the stud 35. Each 35b side wall of the stud can guide the vertical displacement of the cradle in the stud. The support is compact and the stud can guide the cradles in their movements.
Les figures 17 à 20 représentent les différents types de réglage qui peuvent être réalisés avec une section de voie selon les modes de réalisation de l'invention.  Figures 17 to 20 show the different types of adjustment that can be achieved with a section of track according to the embodiments of the invention.
Sur la figure 17 et20, un déplacement vertical, suivant l'axe vertical V, du panneau de voie 20 est réalisé par une action coordonnée sur les vis 38 de réglage des différents appuis du panneau de voie. Cela permet de régler la hauteur du panneau de voie par rapport à la plateforme 15 en ajustant de manière coordonnée les différents berceaux des différents appuis.  In FIG. 17 and 20, a vertical displacement, along the vertical axis V, of the track panel 20 is achieved by a coordinated action on the adjusting screws 38 of the different supports of the track panel. This adjusts the height of the track panel with respect to the platform 15 by adjusting in a coordinated manner the different cradles of the different supports.
Sur la figure 18 et 21, le panneau de voie 20 est pivoté autour d'un axe longitudinal par un réglage du berceau d'un seul côté du panneau. Cela permet de former un dévers sur le tracé de la voie par une inclinaison de la voie.  In Figs. 18 and 21, the track panel 20 is pivoted about a longitudinal axis by a cradle adjustment on one side of the panel. This makes it possible to form a slope on the track layout by a slope of the track.
Une section de voie selon l'invention permet donc de régler la voie selon deux degrés de liberté distincts.  A track section according to the invention therefore allows the track to be adjusted according to two different degrees of freedom.
La figure 22 représente les butées 27, 28 ménagées sous la longrine 22 entre lesquelles le berceau 37 vient se loger pour bloquer tout déplacement longitudinal de la longrine 22. De préférence, chaque longrine ne comprend que deux butées de sorte que dans le cas où une longrine est portée par deux appuis, seul le berceau d'un des deux appuis est en prise avec les deux butées pour assurer un blocage longitudinale de la longrine.  FIG. 22 shows the abutments 27, 28 formed under the sill 22 between which the cradle 37 is housed to block any longitudinal displacement of the sill 22. Preferably, each sill comprises only two abutments so that in the case where a sill is supported by two supports, only the cradle of one of the two supports is engaged with the two stops to ensure longitudinal locking of the sill.
En référence aux figures 12, 23 et 24, chaque paroi latérale 35b comprend au moins un orifice 44 traversant d'axe parallèle à l'axe longitudinal L et apte à recevoir des moyens de désengagement 45 de la cale 36 de la cuvette 43. En particulier, les parois latérales 35b comprennent un orifice 44 agencé en regard d'une cale 36. Dans le présent exemple, deux orifices traversant 44 traversent chacun la paroi latérale 35b de part et d'autre et débouchent chacun dans une cuvette 43. Les moyens de désengagement 45 comprennent un vérin dont la tige 46 est illustrée sur les figures 22 et 23. Sur la figure 22, la tige 46 est insérée dans un orifice traversant 44 et son extrémité est en butée contre un chant 54 latéral de la cale 36. La cale 36 est toujours logée dans la cuvette 43 du fait des plans inclinés vers l'extrémité inférieure de la paroi latérale 35b. La tige 46 exerce un effort sur la cale 36 logée dans la cuvette de manière à l'extraire de la cuvette comme cela est illustré sur la figure 23. With reference to FIGS. 12, 23 and 24, each side wall 35b comprises at least one through-hole 44 having an axis parallel to the longitudinal axis L and able to receive disengagement means 45 from the shim 36 of the bowl 43. In particular, the side walls 35b comprise an orifice 44 arranged opposite a shim 36. In the present example, two through holes 44 each pass through the side wall 35b on either side and open each into a bowl 43. disengagement 45 comprise a jack whose rod 46 is illustrated in Figures 22 and 23. In Figure 22, the rod 46 is inserted into a through hole 44 and its end abuts against a lateral edge 54 of the shim 36. The shim 36 is always housed in the bowl 43 because of the plans inclined towards the lower end of the side wall 35b. The rod 46 exerts a force on the shim 36 housed in the bowl so as to extract it from the bowl as shown in FIG. 23.
Les figures 24 et 25 sont des vues suivant deux modes de réalisation d'un massif métallique 50 permettant de fixer le plot 35 dans la plateforme 15. Dans les deux modes de réalisation, le massif métallique 50 comprend une plaque 51 métallique destinée à venir en contact avec la base 35a de l'appui 35. La plaque présente une forme rectangulaire. Cependant, elle pourrait présenter une autre forme qui soit adaptée à la plateforme et/ou à l'appui 34, 34' . Le massif métallique 50 comprend également une pluralité d'éléments d'implantation 52 s 'étendant depuis la plaque 51 suivant une direction perpendiculaire à ladite plaque 51. Les éléments d'implantation 52 s'étendent suivant l'axe vertical V. De manière avantageuse, mais non limitativement, les éléments d'implantation sont soudés sur la plaque 51 métallique. Bien entendu, d'autres moyens permettant de solidariser les éléments d'implantation à la plaque sont envisageables. La longueur, le diamètre et le nombre d'éléments d'implantation 52 sont déterminés en fonction du sol. Suivant le mode de réalisation illustré sur la figure 24, les éléments d'implantation 52 comprennent des profilés de section en forme de H. Ces profilés sont avantageusement réalisés dans un matériaux métallique tel que l'acier. Suivant le mode de réalisation illustré sur la figure 26, les éléments d'implantation 52 comprennent des tubes 52. Ces tubes sont également avantageusement réalisés dans un matériaux métallique tel que l'acier. Suivant l'exemple de la figure 26, le massif 50 métallique peut comprendre seize tubes soudés sur la plaque 51 métallique. Le massif métallique 50 est destiné à être fixé sur une plateforme 15 par battage ou fonçage. La base 35a de l'appui 35 peut être fixée sur la plaque 51 métallique par collage ou par des moyens de boulonnerie ou tout autre moyen équivalent permettant de solidariser la base 35a de l'appui 35 et la plaque 51 métallique du massif métallique 50.  Figures 24 and 25 are views according to two embodiments of a metal block 50 for fixing the stud 35 in the platform 15. In both embodiments, the metal block 50 comprises a metal plate 51 intended to come into contact with the base 35a of the support 35. The plate has a rectangular shape. However, it could present another form that is adapted to the platform and / or support 34, 34 '. The metal base 50 also comprises a plurality of implantation elements 52 extending from the plate 51 in a direction perpendicular to said plate 51. The implantation elements 52 extend along the vertical axis V. Advantageously , but without limitation, the implantation elements are welded to the metal plate 51. Of course, other means for securing the implantation elements to the plate are conceivable. The length, the diameter and the number of implantation elements 52 are determined according to the ground. According to the embodiment illustrated in Figure 24, the implantation elements 52 comprise section sections in the form of H. These profiles are advantageously made of a metal material such as steel. According to the embodiment illustrated in FIG. 26, the implantation elements 52 comprise tubes 52. These tubes are also advantageously made of a metallic material such as steel. Following the example of FIG. 26, the metal block 50 may comprise sixteen tubes welded to the metal plate 51. The metal block 50 is intended to be fixed on a platform 15 by threshing or driving. The base 35a of the support 35 may be fixed to the metal plate 51 by gluing or by bolting means or any other equivalent means for securing the base 35a of the support 35 and the metal plate 51 of the metal block 50.
Le massif 50 comprend également des moyens de calage du plot. Ces moyens de calage sont agencés sur la plaque métallique. Les moyens de calage 57 comportent comme l'exemple représenté sur la figure 24 des tampons qui sont disposés sur une face supérieure de ladite plaque 51. Chaque tampon est placé à un coin de la plaque 51. Les tampons sont montés au moyen d'organes de fixation tels que des vis ou autres organes adéquats. Ces tampons 51 font office de butée lorsque le plot 35 est monté sur le massif 50. The solid mass 50 also comprises means for wedging the stud. These wedging means are arranged on the metal plate. The wedging means 57 comprise, as in the example shown in FIG. 24, buffers which are arranged on an upper face of said plate 51. Each pad is placed at a corner of the plate 51. The pads are mounted by means of fasteners such as screws or other suitable organs. These buffers 51 serve as a stop when the stud 35 is mounted on the solid mass 50.
La figure 27 est une vue d'une section de voie de transport guidé avec un appui selon le premier mode de réalisation de l'invention, la section de voie étant fixée sur une plateforme 15 par l'intermédiaire des massifs métalliques 50 décrits précédemment. La plateforme 15 comprend typiquement une partie supérieure 56 du terrassement et un corps de remblai 55. Ces massifs 50 métalliques sont de préférence déterminés de telle sorte qu'une fois ancrés dans la plateforme 15, éléments d'implantation 52 s'étendent jusqu'au corps 55 de remblai de la plateforme 15. En outre, de préférence, la surface supérieure de la plateforme 15 est légèrement inclinée, par exemple de l'ordre de 4% pour faciliter son drainage. Une section selon l'invention permet de compenser si nécessaire cette légère inclinaison de la plateforme par un réglage inverse des appuis.  Figure 27 is a view of a guided transport section section with a support according to the first embodiment of the invention, the track section being fixed on a platform 15 through the metal masses 50 described above. The platform 15 typically comprises an upper portion 56 of the earthwork and a backfill body 55. These metal beds 50 are preferably determined so that once anchored in the platform 15, implantation elements 52 extend to 55 body embankment of the platform 15. In addition, preferably, the upper surface of the platform 15 is slightly inclined, for example of the order of 4% to facilitate drainage. A section according to the invention makes it possible to compensate if necessary this slight inclination of the platform by an inverse adjustment of the supports.
L'invention ne se limite pas aux seuls modes de réalisation décrits. En particulier, d'autres types d'architectures pour les appuis peuvent être envisagés pour assurer la fonction de déplacement vertical des berceaux. Selon les modes de réalisation décrits, le déplacement vertical de chaque berceau résulte d'un déplacement horizontal ou quasi-horizontal de la cale en coin. On peut imaginer d'autres cinématiques pour arriver à un déplacement vertical du berceau par rapport au plot pour assurer un réglage en hauteur et/ou en inclinaison du panneau de voie porté par les appuis.  The invention is not limited to the embodiments described. In particular, other types of architectures for the supports can be envisaged to ensure the function of vertical displacement of the cradles. According to the embodiments described, the vertical displacement of each cradle results from a horizontal or almost horizontal displacement of the wedge wedge. One can imagine other cutscenes to achieve a vertical displacement of the cradle relative to the stud to ensure a height adjustment and / or inclination of the track panel carried by the supports.
