Description

La présente invention concerne une voie de roulement continue sur viaduc selon le préambule de la revendication 1, ainsi qu'un dispositif anti-soulèvement adapté à ladite voie de roulement.The present invention relates to a continuous viaduct raceway according to the preamble of claim 1, and an anti-lift device adapted to said raceway.

De manière générale, la présente invention se rapporte au domaine des voies de roulement rigides sur ouvrage de pont destinées à supporter le déplacement d'un véhicule, en particulier un véhicule guidé. Par véhicule guidé, il est fait référence notamment à un moyen de transport en commun tels que bus, trolleybus, tramways, métros, trains ou unités de train, etc., pour lesquels le guidage est assuré en particulier par au moins un rail de guidage disposé sur la voie de roulement.In general, the present invention relates to the field of rigid rolling tracks on a bridge structure intended to support the movement of a vehicle, in particular a guided vehicle. By guided vehicle, reference is made in particular to a means of public transport such as buses, trolleybuses, trams, subways, trains or train units, etc., for which guidance is provided in particular by at least one guide rail disposed on the track.

Typiquement, un pont (ou viaduc) destiné à supporter une voie de roulement comprend un ensemble de piles (ou piliers) réparties entre une première culée située à une extrémité dudit pont, et une seconde culée située à l'autre extrémité dudit pont. Lesdites piles et culées sont destinées à supporter des segments de pont qui sont par exemple des poutres métalliques ou des éléments en béton préfabriqués destinés à former une surface de support pour la voie de roulement, communément appelée le tablier dudit pont. Chacun desdits segments répartis entre la première et la dernière pile prend appui à chacune de ses extrémités sur une desdites piles du pont s'étendant ainsi d'une pile à l'autre, l'extrémité d'un segment étant séparée de l'extrémité d'un segment adjacent par un espace communément appelé « joint d'ouvrage ». Optionnellement, ledit segment peut être supporté par une ou plusieurs autres piles disposées entre lesdites piles d'extrémités. Le premier et le dernier segment prennent quant à eux appui respectivement sur la première culée d'extrémité et la première pile, et sur la dernière pile et la seconde culée d'extrémité. Les différents éléments dudit pont (piles, culées, segments, voie) sont choisis en fonction des caractéristiques de charge et d'utilisation du pont.Typically, a bridge (or viaduct) for supporting a raceway comprises a set of piles (or pillars) distributed between a first abutment at one end of said bridge, and a second abutment located at the other end of said bridge. Said piers and abutments are intended to support bridge segments which are for example metal beams or prefabricated concrete elements intended to form a support surface for the raceway, commonly called the apron of said bridge. Each of said segments distributed between the first and the last stack is supported at each of its ends on one of said piles of the bridge thus extending from one stack to another, the end of a segment being separated from the end an adjacent segment by an area commonly called "seal of work". Optionally, said segment may be supported by one or more other cells disposed between said stacks of ends. The first and the last segment respectively support the first end abutment and the first stack, and the last stack and the second end abutment. The various elements of said bridge (stacks, abutments, segments, track) are chosen according to the load characteristics and use of the bridge.

Lesdits segments forment ainsi typiquement une surface discontinue destinée à supporter la voie de roulement. Généralement, lesdits segments prennent appui sur lesdites piles du pont au moyen de dispositifs d'appuis fixes et/ou glissants, qui tolèrent un déplacement d'au moins une extrémité dudit segment, ledit déplacement pouvant être par exemple engendré par des différences de températures et/ou le passage du véhicule sur ledit pont. Les voies de roulement sur ouvrage de pont ou de viaduc sont également conçues pour supporter des déformations thermiques et/ou mécaniques (p. ex. dues au passage d'un véhicule) qui peuvent survenir lors d'une utilisation normale de ladite voie. Différentes solutions permettent de compenser ces déformations. Traditionnellement, ladite voie peut être constituée de plusieurs tronçons de voie, chacun desdits tronçons de voie étant ancré à un desdits segment et séparé d'un tronçon directement voisin par un joint de dilatation transversal. Sous cette forme, ladite voie est discontinue et comprend, répartis selon sa longueur, un certain nombre de joints de dilatation séparant les différents tronçons et destinés à compenser la dilatation longitudinale de la voie sous l'effet de changements de température et/ou du passage d'un véhicule. Malheureusement, une telle solution n'est par exemple pas adaptée au milieu urbain, car elle provoque des nuisances sonores, diminue le confort des passagers, requiert des contrôles et une maintenance fréquente, et peut accroitre prématurément l'usure des pneumatiques ou roues du véhicule circulant sur ladite voie de roulement. De plus, la nécessité de répartir des joints de dilatation le long de la voie de roulement augmente le coût de réalisation de l'ouvrage d'art que sont les ponts ou les viaducs, et des tensions peuvent être engendrées dans le segment ou la section de voie lorsque les matériaux dudit segment et de ladite voie répondent différemment à des changements de température.Said segments thus typically form a discontinuous surface for supporting the track. Generally, said segments bear on said piles of the bridge by means of fixed and / or sliding support devices, which tolerate a displacement of at least one end of said segment, said displacement being able for example to be generated by differences in temperatures and / or the passage of the vehicle on said bridge. Bearings on a bridge or viaduct structure are also designed to withstand thermal and / or mechanical deformations (eg due to vehicle passage) that may occur during normal use of said track. Different solutions make it possible to compensate for these deformations. Traditionally, said track may consist of several track sections, each of said track sections being anchored to one of said segments and separated from a directly adjacent section by a transverse expansion joint. In this form, said track is discontinuous and comprises, distributed along its length, a number of expansion joints separating the different sections and intended to compensate for the longitudinal expansion of the track under the effect of temperature changes and / or the passage of a vehicle. Unfortunately, such a solution is, for example, not suited to the urban environment, because it causes noise pollution, reduces passenger comfort, requires checks and frequent maintenance, and may prematurely increase the wear of the tires or wheels of the vehicle. traveling on said track. In addition, the need to distribute expansion joints along the raceway increases the cost of construction of the bridge or viaduct, and stresses can be generated in the segment or section. when the materials of said segment and said path respond differently to changes in temperature.

Afin d'éviter ces problèmes, des voies continues ont été proposées et développées dans l'art de la technique antérieure. Ces dernières comprennent par exemple:

  • une dalle continue s'étendant d'une extrémité à l'autre dudit pont et destinée à reposer sur une surface supérieure desdits segments ;
  • une plaque de franchissement destinée à couvrir les extrémités directement voisines de deux segments successifs, s'étendant ainsi d'une extrémité d'un segment à l'extrémité d'un autre segment immédiatement voisin, ladite plaque étant d'une largeur équivalente à la largeur de la voie, caractérisée par une longueur et une élasticité suffisante pour absorber une flexion desdits segments, et donc un déplacement vertical desdites extrémités sans le transmettre à ladite dalle, ladite plaque de franchissement étant disposée entre ladite dalle continue et la surface supérieure desdits segments de voie ;
  • une couche antifriction située à l'interface entre la surface supérieure dudit segment et la surface inférieure de la dalle continue, formant ainsi un plan de glissement entre lesdites plaques de franchissement successives, ladite couche antifriction permettant à ladite dalle continue d'avoir au moins un degré de liberté longitudinal par rapport à la surface supérieur dudit segment ;
  • des dispositifs d'ancrage pour fixer et solidariser ladite dalle continue auxdits segments et des butées latérales fixées auxdits segments et réparties latéralement de chaque côté de ladite voie, le long de cette dernière, afin de soutenir des efforts latéraux pouvant survenir lors d'un déplacement d'un véhicule guidé sur ladite voie ou engendrés par la dalle elle-même.
In order to avoid these problems, continuous paths have been proposed and developed in the prior art. These include for example:

La figure 1 et la figure 2 présentent schématiquement un exemple de réalisation d'une voie 5 de roulement selon l'invention dans une vue de face et de dessus respectivement. Ladite voie 5 de roulement est une voie continue sur ouvrage de pont 1, ledit ouvrage de pont 1 comprenant au moins deux segments 4 de pont, une première culée 31 située à une extrémité dudit pont 1 et une seconde culée 32 située à l'autre extrémité dudit pont, et une structure porteuse formée de piles 2 réparties entre la première culée 31 et la seconde culée 32 pour supporter lesdits segments 4. En particulier, lesdits segments peuvent reposer à leurs extrémités sur des dispositifs d'appuis fixes 22 et/ou glissants 23 tel que connu de l'homme du métier. Chaque segment est notamment séparé du segment 4 immédiatement voisin par un joint d'ouvrage 23. La surface supérieure desdits segments 4 forme ainsi une surface d'appui discontinue pour la voie 5 de roulement.The figure 1 and the figure 2 schematically show an embodiment of a track 5 according to the invention in a front view and from above respectively. Said track 5 is a continuous track on bridge structure 1, said bridge structure 1 comprising at least two bridge segments 4, a first abutment 31 located at one end of said bridge 1 and a second abutment 32 located at the other end. end of said bridge, and a carrier structure formed of stacks 2 distributed between the first abutment 31 and the second abutment 32 to support said segments 4. In particular, said segments may rest at their ends on fixed support devices 22 and / or 23 as known to those skilled in the art. Each segment is in particular separated from the segment 4 immediately adjacent by a construction joint 23. The upper surface of said segments 4 thus forms a discontinuous bearing surface for the track 5.

Dans un mode de réalisation préféré d'une voie 5 de roulement selon l'invention illustré par les figures 1 à 3, ladite voie 5 comprend :

  • une dalle 50 continue s'étendant d'une extrémité à l'autre dudit pont 1 et reposant sur la surface supérieure desdits segments 4 ;
  • une couche antifriction 55 située sous la dalle 50 continue configurée pour servir d'interface entre la surface supérieure dudit segment 4 et la surface inférieure de la dalle 50 continue, ladite couche antifriction 55 définissant ainsi un plan de glissement pour ladite dalle 50 continue et permettant à cette dernière d'avoir au moins un degré de liberté longitudinal par rapport à la surface supérieur dudit segment 4, ladite couche antifriction 55 s'étendant préférentiellement de manière continue sous toute la surface inférieure de ladite dalle 50 continue ;
  • une plaque de franchissement 53 située sous la dalle 50 continue, en particulier sous la couche antifriction 55, positionnée de façon à s'étendre d'une extrémité d'un segment à l'extrémité d'un autre segment directement adjacent de façon à couvrir les extrémités adjacentes desdits segments 4 afin de compenser des mouvements de flexion ou rotation aux appuis desdits segments 4.
In a preferred embodiment of a track 5 according to the invention illustrated by the Figures 1 to 3 said path 5 comprises:
  • a continuous slab 50 extending from one end to the other of said bridge 1 and resting on the upper surface of said segments 4;
  • an anti-friction layer 55 located under the continuous slab 50 configured to serve as an interface between the upper surface of said segment 4 and the lower surface of the continuous slab 50, said anti-friction layer 55 thus defining a sliding plane for said continuous slab 50 and allowing to the latter to have at least one longitudinal degree of freedom with respect to the upper surface of said segment 4, said antifriction layer 55 extending preferably continuously over the entire lower surface of said slab 50 continues;
  • a crossing plate 53 located under the continuous slab 50, in particular under the antifriction layer 55, positioned to extend from one end of a segment to the end of another directly adjacent segment so as to cover the adjacent ends of said segments 4 to compensate for bending or rotation movements at the supports of said segments 4.

Préférentiellement, la couche antifriction 55 comprend une première couche géotextile 551 destinée à être en contact avec ladite dalle 50 continue, par exemple en étant collée/fixée à la surface inférieure de ladite dalle 50 continue, et une seconde couche géotextile 552 destinée à être en contact avec lesdits segments 4, par exemple en étant collée à la surface supérieure desdits segments, ladite première et seconde couches géotextiles 551, 552 prenant en sandwich une ou plusieurs couches polyane 553 (ou geomembrane). Avantageusement, la configuration en sandwich géotextile/polyane/géotextile de la couche antifriction améliore le glissement de la dalle continue sur lesdits segments.Preferably, the antifriction layer 55 comprises a first geotextile layer 551 intended to be in contact with said continuous slab 50, for example by being glued / fixed to the lower surface of said continuous slab 50, and a second geotextile layer 552 intended to be in contact with said continuous slab 50, contact with said segments 4, for example by being glued to the upper surface of said segments, said first and second geotextile layers 551, 552 sandwiching one or more polyane layers 553 (or geomembrane). Advantageously, the geotextile / polyane / geotextile sandwich configuration of the anti-friction layer improves the sliding of the continuous slab on said segments.

Préférentiellement, les plaques de franchissement 53 sont des panneaux en polystyrène extrudé (type Styrodur). En particulier, lesdits segments 4 comprennent à leurs extrémités des réservations 41 dont les dimensions correspondent aux dimensions des plaques de franchissement 53 de façon à ce que lorsque lesdites plaques de franchissement 53 sont insérées dans lesdites réservations 41, la surface supérieure dudit segment 4 et la surface supérieure de ladite plaque de franchissement 53 coïncident, ou autrement dit, soient au même niveau de façon à former une surface continue. Avantageusement, cela permet de maintenir une continuité du niveau sous la dalle 50 continue, favorisant dès lors le glissement de cette dernière sur la surface continue formée par les surfaces supérieures des segments 4 et les surfaces supérieures des plaques de franchissement 53.Preferably, the crossing plates 53 are extruded polystyrene panels (Styrodur type). In particular, said segments 4 comprise at their ends reservations 41 whose dimensions correspond to the dimensions of the crossing plates 53 so that when said crossing plates 53 are inserted in said reservations 41, the upper surface of said segment 4 and the upper surface of said crossing plate 53 coincide, or in other words, are at the same level so as to form a continuous surface. Advantageously, this makes it possible to maintain a continuity of the level under the continuous slab 50, thus favoring the sliding of the latter on the continuous surface formed by the upper surfaces of the segments 4 and the upper surfaces of the crossing plates 53.

Une particularité de la voie 5 de roulement selon l'invention est qu'elle comprend au moins un dispositif anti-soulèvement 54 configuré pour être solidarisable à un segment 4, par exemple en utilisant un système de boulonnerie et douilles d'ancrages pré-implantées dans ledit segment 4, ou encore par ferraillage et coulage de béton afin de fixer une partie dudit dispositif anti-soulèvement audit segment 4. Le dispositif anti-soulèvement 54 selon l'invention est de plus capable de limiter une translation ou déplacement de ladite dalle 50 dans une direction N perpendiculaire au plan de glissement tout en permettant une liberté de mouvement de ladite dalle sur le plan de glissement défini par ladite couche antifriction 55. Du fait de sa construction en un monobloc libre de mouvement sur la surface de glissement définie par la couche de friction, la voie 5 de roulement selon l'invention est particulièrement bien adaptée au support d'un rail 6 de type LRS (long rail soudé) puisque sa surface permettant la fixation dudit rail ne présente aucune discontinuité.A feature of the track 5 according to the invention is that it comprises at least one anti-lifting device 54 configured to be securable to a segment 4, for example using a system of bolts and anchor sleeves pre-implanted in said segment 4, or else by reinforcement and pouring of concrete in order to fix a portion of said anti-lifting device to said segment 4. The anti-lifting device 54 according to the invention is moreover capable of limiting a translation or displacement of said slab 50 in a direction N perpendicular to the sliding plane while allowing freedom of movement of said slab on the sliding plane defined by said antifriction layer 55. Due to its construction as a free monoblock movement on the sliding surface defined by the friction layer, the track 5 according to the invention is particularly well suited to the support of a rail 6 type LRS (long welded rail) since its surface for fixing said rail has no discontinuity.

  • une tige cylindrique 72, solidaire à une de ses extrémités à ladite base 71 et comprenant à son autre extrémité un disque 73 de rayon supérieur au rayon de ladite tige cylindrique 72 et d'épaisseur E (E étant l'épaisseur dudit disque selon ladite direction N) ;
ledit disque 73 et au moins une partie de ladite tige 72 étant enfermés dans ladite tête 543 du dispositif anti-soulèvement 54. A cette fin, ladite tête 543 comprend une partie cylindrique creuse 82 destinée à accueillir ladite tige cylindrique 72 et à la guider, l'extrémité de ladite partie cylindrique creuse 82 dirigée vers ladite base 71 du corps 542 du dispositif anti-soulèvement 54 étant ouverte et son autre extrémité étant fermée par un chapeau cylindrique 83 creux de rayon supérieur au rayon dudit disque 73 du corps 542 du dispositif anti-soulèvement 54 et de hauteur intérieure sensiblement égale ou supérieure à l'épaisseur E afin de pouvoir accueillir ledit disque 73 de façon à ce que ce dernier soit maintenu verticalement tout en autorisant un léger jeu selon la direction N et en permettant à ce dernier de se mouvoir selon un plan parallèle audit plan de glissement. Selon cet autre mode préféré de réalisation, l'intérieur dudit chapeau cylindrique 83 emprisonne le disque 73 et fait office de butée. Avantageusement, l'intérieur dudit chapeau cylindrique 83 et/ou de la partie cylindrique creuse 82 peuvent être recouvert d'un matériau antifriction facilitant le glissement relatif du corps et de la tête lorsqu'ils sont en contact. Préférentiellement, ce dispositif anti-soulèvement est destiné à être positionné sous ladite dalle continue, ledit corps 542 étant fixé audit segment 4, et ladite tête 543 étant fixée à ladite dalle. Bien entendu, l'homme du métier saura réaliser un dispositif inversé, avec un corps fixé à la dalle, et une tête fixée au segment, ou également appliqué le concept à une butée latérale, le corps étant fixé dès lors à la butée latérale, et la tête à ladite dalle, ou inversement. La figure 6 présente finalement une vue de dessus d'une implantation d'un ou plusieurs dispositifs anti-soulèvement 54 dans ladite dalle 50 selon cet autre mode préféré de réalisation.Preferably, said continuous path comprises continuous or discontinuous lateral stops 541 distributed on each side of said slab 50 in order to maintain laterally the latter, each lateral abutment being notably integral. of one or more segments 4. In order to avoid the use of lateral stops, the present invention further proposes another preferred embodiment illustrated in FIG. Figures 5-6 and based on another constructive arrangement of the anti-lift device according to the invention. According to this other constructive arrangement, said head 543 of said anti-lifting device 54 envelops at least a portion of said body 542 so as to create a coupling allowing relative movement of said head 543 with respect to said body 542 in a direction parallel to said sliding plane while limiting the relative displacement of the head relative to the body in a direction N perpendicular to said sliding plane. For example, the body 542 of the anti-lift device comprises:
  • a base 71 intended to be fixed / anchored to said segment 4, for example by screwing or pouring concrete or by means, for example, of anchoring sleeves pre-implanted in said segment 4 in order to make said base 71 integral with said segment 4;
  • a cylindrical rod 72 secured at one of its ends to said base 71 and comprising at its other end a disk 73 of radius greater than the radius of said cylindrical rod 72 and of thickness E (E being the thickness of said disk in said direction NOT) ;
said disc 73 and at least a part of said rod 72 being enclosed in said head 543 of the anti-lifting device 54. For this purpose, said head 543 comprises a hollow cylindrical portion 82 intended to receive said cylindrical rod 72 and to guide it, the end of said hollow cylindrical portion 82 directed towards said base 71 of the body 542 of the anti-lifting device 54 being open and its other end being closed by a hollow cylindrical cap 83 of radius greater than the radius of said disk 73 of the body 542 of the device anti-lift 54 and inner height substantially equal to or greater than the thickness E so to be able to accommodate said disc 73 so that the latter is held vertically while allowing a slight clearance in the direction N and allowing the latter to move in a plane parallel to said sliding plane. According to this other preferred embodiment, the inside of said cylindrical cap 83 traps the disc 73 and serves as a stop. Advantageously, the inside of said cylindrical cap 83 and / or the hollow cylindrical portion 82 may be covered with antifriction material facilitating the relative sliding of the body and the head when in contact. Preferably, this anti-lifting device is intended to be positioned under said continuous slab, said body 542 being fixed to said segment 4, and said head 543 being fixed to said slab. Of course, those skilled in the art will be able to produce an inverted device, with a body fixed to the slab, and a head fixed to the segment, or also applied the concept to a lateral abutment, the body being thus fixed to the lateral abutment, and the head to said slab, or vice versa. The figure 6 finally shows a top view of an implantation of one or more anti-lifting devices 54 in said slab 50 according to this other preferred embodiment.

Préférentiellement, d'autres dispositions constructives 54R, 54E pour la tête 543 et le corps 542 selon l'invention peuvent être réalisées par l'homme du métier, lesdites autres dispositions constructives 54R, 54E étant toutes caractérisées en ce qu'elles conservent la caractéristique de maintien vertical de la tête par rapport au corps tout en autorisant d'une part le léger jeu selon la direction N, et d'autre part ledit mouvement relatif de la tête par rapport au corps dans un plan parallèle audit plan de glissement lorsque ledit dispositif anti-soulèvement est monté sur/dans la voie de roulement continue selon l'invention. Ces autres dispositions constructives 54R, 54E sont également illustrées en Fig. 6.Preferably, other constructive arrangements 54R, 54E for the head 543 and the body 542 according to the invention can be made by those skilled in the art, said other constructive arrangements 54R, 54E being all characterized in that they retain the characteristic vertical holding of the head relative to the body while allowing on the one hand the slight play in the direction N, and secondly said relative movement of the head relative to the body in a plane parallel to said sliding plane when said anti-lift device is mounted on / in the continuous raceway according to the invention. These other constructive arrangements 54R, 54E are also illustrated in Fig. 6 .

Par exemple, ledit corps peut comprendre une base destinée à être fixée/ancrée audit segment 4, ladite base étant attachée à une tige ou structure sensiblement verticale surmontée par une structure sensiblement horizontale par rapport à ladite tige ou structure verticale, ladite structure sensiblement horizontale étant d'épaisseur E régulière, de forme oblongue, par exemple elliptique ou rectangulaire comme illustré par les références 54E et 54R respectivement, la section de ladite structure sensiblement horizontale selon un plan horizontal (i.e. parallèle au plan de glissement lorsque ledit dispositif anti-soulèvement équipe ladite voie de roulement) étant de dimensions supérieures à la section de ladite tige ou structure verticale selon un plan parallèle audit plan horizontal. Ladite tête quant à elle a une forme adaptée pour enfermer au moins une partie de ladite tige ou structure sensiblement verticale ainsi que pour enfermer/emprisonner ladite structure sensiblement horizontale de façon à autoriser un mouvement relatif de la tête par rapport audit corps, ledit mouvement autorisé selon la longueur de ladite forme oblongue étant en particulier supérieur au mouvement autorisé selon la largeur de ladite forme oblongue. A cette fin, ladite tête 543 comprend une partie creuse destinée à accueillir ladite tige ou structure verticale et à la guider, l'extrémité de ladite partie creuse dirigée vers ladite base du corps 542 du dispositif anti-soulèvement 54 étant ouverte et son autre extrémité étant fermée par un chapeau creux de dimensions supérieures aux dimensions extérieures de ladite structure sensiblement horizontale et de hauteur intérieure sensiblement égale ou supérieure à l'épaisseur E afin de pouvoir accueillir en son sein ladite structure sensiblement horizontale. Le chapeau creux est ainsi préférentiellement dimensionné de façon à ce que le déplacement permis pour ladite structure sensiblement horizontale à l'intérieur dudit chapeau soit supérieur dans la direction de l'axe longitudinale (longueur) de ladite structure horizontale à son déplacement dans la direction de son axe transversal (largeur). Selon ces autres dispositions constructives 54E, 54R, le dispositif anti-soulèvement est configuré pour être monté dans/sur ladite voie continue de façon à ce que l'axe longitudinal de la structure oblongue soit aligné avec l'axe longitudinal de ladite voie ou dalle. Avantageusement, ces autres dispositions constructives du dispositif anti-soulèvement selon l'invention favorisent le déplacement longitudinal de ladite dalle comparé à son déplacement transversal.For example, said body may comprise a base intended to be fixed / anchored to said segment 4, said base being attached to a substantially vertical rod or structure surmounted by a substantially horizontal structure with respect to said rod or vertical structure, said substantially horizontal structure being of regular thickness E, oblong, for example elliptical or rectangular as illustrated by references 54E and 54R respectively, the section of said substantially horizontal structure in a horizontal plane (ie parallel to the sliding plane when said anti-uplift team said raceway) being larger than the section of said rod or vertical structure in a plane parallel to said horizontal plane. Said head in turn has a shape adapted to enclose at least a portion of said rod or substantially vertical structure and to enclose / imprison said substantially horizontal structure so as to allow relative movement of the head relative to said body, said authorized movement according to the length of said oblong shape being in particular greater than the authorized movement according to the width of said oblong shape. For this purpose, said head 543 comprises a hollow portion intended to receive said vertical rod or structure and to guide it, the end of said hollow portion directed towards said base of the body 542 of the anti-lifting device 54 being open and its other end being closed by a hollow cap of dimensions greater than the outer dimensions of said substantially horizontal structure and inner height substantially equal to or greater than the thickness E in order to accommodate within said substantially horizontal structure. The hollow cap is thus preferably dimensioned so that the displacement allowed for said substantially horizontal structure inside said cap is greater in the direction of the longitudinal axis (length) of said horizontal structure to its displacement. in the direction of its transverse axis (width). According to these other constructive arrangements 54E, 54R, the anti-lifting device is configured to be mounted in / on said continuous track so that the longitudinal axis of the oblong structure is aligned with the longitudinal axis of said track or slab . Advantageously, these other constructive provisions of the anti-lifting device according to the invention promote the longitudinal displacement of said slab compared to its transverse displacement.

Avantageusement, le dispositif anti-soulèvement 54 selon lesdites autres dispositions constructives facilite la construction de ladite voie 5. En effet, lors de la construction de cette dernière, il est par exemple possible de positionner, puis fixer le corps 542 de chaque dispositif anti-soulèvement 54 à un segment 4 dudit pont 1 ou à une butée latérale 541, la tête 543 dudit dispositif anti-soulèvement restant libre dans un premier temps. Puis, dans un second temps, il est possible de construire la dalle 50 continue de façon à ce qu'elle soit solidaire uniquement de ladite tête 543 dudit dispositif anti-soulèvement. De cette façon, la dalle 50 continue et ledit segment 4 sont couplés verticalement de façon à autoriser un déplacement vertical pour la dalle 50, tout en lui permettant simultanément de se mouvoir dans un plan parallèle audit plan de glissement. En effet, puisque par exemple la tige 72 et le disque 73 du corps 542 ont des rayons inférieurs aux rayons respectivement de la partie cylindrique creuse 82 et du chapeau 83 de la tête 543 du dispositif anti-soulèvement, cette différence de rayon autorise une liberté de déplacement de la tête 543 du dispositif anti-soulèvement par rapport audit corps 542 lorsque ce dernier est fixé audit segment 4. Préférentiellement, un matériau élastique ou compressible remplit l'espace situé entre la partie creuse, par exemple la partie cylindrique creuse 82, et ladite tige 72 et/ou entre ledit chapeau 83 et ladite structure sensiblement horizontale, par exemple ledit disque 73, de façon à s'opposer à un déplacement de ladite tige 72 dans ladite partie creuse. Par exemple et à cette fin, les surfaces extérieures circulaires de ladite tige 72 et/ou dudit disque 73 sont recouvertes par une couche dudit matériau élastique/compressible. Ledit corps 542 et ladite tête 543 sont quant à eux préférentiellement en métal.Advantageously, the anti-lifting device 54 according to said other constructive arrangements facilitates the construction of said track 5. Indeed, during the construction of the latter, it is for example possible to position and then fix the body 542 of each anti-lock device. lifting 54 to a segment 4 of said bridge 1 or to a lateral stop 541, the head 543 of said anti-lift device remaining free at first. Then, in a second step, it is possible to build the continuous slab 50 so that it is integral only with said head 543 of said anti-lifting device. In this way, the slab 50 continues and said segment 4 are coupled vertically so as to allow a vertical displacement for the slab 50, while simultaneously allowing it to move in a plane parallel to said sliding plane. Indeed, since for example the rod 72 and the disc 73 of the body 542 have lower radii respectively of the hollow cylindrical portion 82 and the cap 83 of the head 543 of the anti-lift device, this difference in radius allows a freedom moving the head 543 of the anti-lifting device relative to said body 542 when the latter is attached to said segment 4. Preferably, an elastic or compressible material fills the space between the hollow part, for example the hollow cylindrical portion 82, and said rod 72 and / or between said cap 83 and said substantially horizontal structure, for example said disc 73, so as to oppose a displacement of said rod 72 in said hollow portion. For example and for this purpose, the outer circular surfaces of said rod 72 and / or said disc 73 are covered by a layer of said elastic / compressible material. Said body 542 and said head 543 are in turn preferentially metal.

Préférentiellement, ladite voie 5 continue comprend, à chacune des extrémités de ladite dalle 50 continue selon sa longueur, une ou plusieurs culées d'ancrages 51, 52 destinées à reprendre des efforts longitudinaux apparaissant dans ladite dalle 50 continue. Ladite culée d'ancrage 51, 52 peut par exemple être ancrée à une culée d'extrémité 31 dudit pont ou à un radier 32.Preferably, said continuous path 5 comprises, at each end of said slab 50 continuous along its length, one or more abutments anchors 51, 52 intended to take up longitudinal forces appearing in said slab 50 continues. Said anchor 51, 52 may for example be anchored to an end abutment 31 of said deck or to a raft 32.

En résumé, la présente invention propose une voie continue sur ouvrage de pont comprenant une dalle complètement désolidarisée de la surface formée par une face supérieure du tablier, i.e. des segments de ponts, garantissant ainsi un déplacement libre de ladite dalle sur ledit tablier tout en limitant un déplacement vertical et/ou transversal de ladite dalle, au moyen de dispositifs anti-soulèvement capables de reprendre des efforts normaux au tablier exercés par exemple lors d'un soulèvement de ladite dalle 50 et subsidiairement des efforts transversaux, lesdits dispositifs anti-soulèvement pouvant notamment coopérer avec des butées latérales pour ladite reprise des efforts transversaux. Ladite voie de roulement selon l'invention est ainsi caractérisée en ce qu'elle peut comprendre une pluralité de dispositifs anti-soulèvement répartis selon sa longueur, disposés par exemple latéralement de chaque côté de ladite dalle (50) comme représenté dans les figures 1-4 et/ou ancrés dans ladite dalle, par exemple comme représenté en figures 5 et 6.In summary, the present invention proposes a continuous path on a bridge structure comprising a slab completely separated from the surface formed by an upper face of the deck, ie bridge segments, thereby guaranteeing free movement of said slab on said deck while limiting a vertical and / or transverse displacement of said slab, by means of anti-lifting devices capable of resuming normal stresses to the deck exerted for example during an uplift of said slab 50 and subsidiarily transverse forces, said anti-lifting devices being able to in particular cooperate with lateral stops for said recovery of transverse forces. Said rolling track according to the invention is thus characterized in that it may comprise a plurality of anti-lifting devices distributed along its length, arranged for example laterally on each side of said slab (50) as shown in FIGS. Figures 1-4 and / or anchored in said slab, for example as represented in Figures 5 and 6 .
