Abstract
Description
La présente invention a pour objet une voie ferrée notamment en zone urbaine, comprenant au moins une traverse incorporée à une dalle support bétonnée du type "biblocs" comportant essentiellement deux blochets latéraux reliés par une entretoise métallique, un rail étant fixé sur chaque blochet par des fixations d'attache de rail.The subject of the present invention is a railway track, particularly in the area urban, comprising at least one cross member incorporated into a concrete support slab of the "biblock" type essentially comprising two lateral blocks connected by a metal spacer, a rail being fixed on each block by fastening fixings of rail.
Actuellement, il existe deux techniques principales pour la réalisation de voies ferrées en zones urbaines :
- la première consiste à réaliser des voies sans traverse avec ancrage des fixations de rail directement dans la dalle support de voie, les rails étant prépositionnés à l'aide de mannequins avant le coulage de la dalle support. Cette technique est lourde à mettre en oeuvre et d'un coût élevé car elle fait appel à une main d'oeuvre importante. En outre, elle ne permet que des cadences de pose lentes et n'autorise pas l'utilisation de dispositif d'amortissement performant.
- la deuxième utilise des traverses classiques prépositionnées avant coulage de la dalle en béton qui supporte l'ensemble de la voie. Ces traverses ont, notamment au niveau de la zone d'appui du rail, une épaisseur importante entraínant un coût élevé pour la réalisation des voies. De plus, ces traverses ne disposent pas de dispositif permettant de lier les traverses à la dalle support.
- the first consists in making tracks without a crosspiece with anchoring the rail fasteners directly in the track support slab, the rails being pre-positioned using mannequins before the casting of the support slab. This technique is cumbersome to implement and of a high cost because it requires a large workforce. In addition, it only allows slow installation rates and does not allow the use of an efficient damping device.
- the second uses conventional pre-positioned sleepers before pouring the concrete slab which supports the entire track. These sleepers have, in particular at the support area of the rail, a significant thickness resulting in a high cost for the realization of the tracks. In addition, these sleepers do not have a device to link the sleepers to the support slab.
Le but de l'invention est de pallier les inconvénients des traverses de l'art antérieur telles que décrites par exemple dans les documents FR 1 387179 A et EP 0 465 390 A, ces traverses devant rester d'épaisseur faible au niveau des blochets tout en permettant un drainage des eaux de ruissellement. The object of the invention is to overcome the drawbacks of the sleepers of the art as described for example in documents FR 1 387179 A and EP 0 465 390 A, these sleepers must remain thin at the level of the blocks while allowing drainage of runoff water.
Conformément à l'invention, on propose à cette fin une voie ferrée notamment en zone urbaine, comprenant au moins une traverse incorporée à une dalle support bétonnée du type biblocs comportant deux blochets latéraux reliés par une entretoise métallique, un rail étant fixé sur chaque blochet par des fixations d'attache de rail, caractérisée en ce que l'épaisseur des blochets sous l'appui du rail est réduite par rapport à celle des zones adjacentes du blochet , et en ce que l'entretoise comporte en partie centrale un cintrage permettant la réalisation dans la dalle support, sensiblement suivant l'axe de la voie et au-dessus de ladite partie centrale, d'un conduit de drainage des eaux de ruissellement communiquant avec la face supérieure de la dalle. In accordance with the invention, a railway track is proposed for this purpose. especially in urban areas, comprising at least one incorporated cross member a concrete block of the biblock type comprising two blocks side connected by a metal spacer, a rail being fixed on each block by rail fastening fixings, characterized in that the thickness of the blocks under the rail support is reduced compared to that of the zones adjacent to the block, and in that the spacer comprises in the central part a bending allowing the realization in the support slab, substantially along the axis of the track and above said central part, of a drainage runoff communicating with the upper face of the slab.
On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux dessins annexés dans lesquels :
- La figure 1 est une vue en coupe transversale par rapport à l'axe de la voie,
- La figure 2 est une vue de dessus d'une traverse .
- FIG. 1 is a view in cross section with respect to the axis of the track,
- Figure 2 is a top view of a cross member.
Une traverse (1) de type biblocs se présente sous la forme de blochets latéraux (2,3) en béton armé reliés entre eux par une entretoise (4) dont les parties latérales (4a,4b) sont prises dans le corps en béton de chaque blochet (2,3). L'entretoise confère ainsi à la traverse une rigidité facilitant les phases de manutention et de pose de ladite traverse.A cross-piece (1) of the biblock type is in the form of reinforced concrete side blocks (2,3) interconnected by a spacer (4) whose lateral parts (4a, 4b) are taken in the concrete body of each block (2,3). The spacer thus gives the cross member a rigidity facilitating the phases of handling and installation of said crosspiece.
Les blochets sont scellés dans une dalle support (12).The blocks are sealed in a support slab (12).
La zone d'appui (5,6) du rail (7,8) de chaque blochet (2,3) présente conformément à l'invention une épaisseur réduite par exemple d'une épaisseur d'environ 120 mm.The bearing area (5,6) of the rail (7,8) of each block (2,3) has in accordance with the invention a thickness reduced, for example by a thickness about 120 mm.
En outre, dans le mode de réalisation représenté, l'entretoise (4) comporte en section centrale un cintrage (16) vers le bas permettant de réaliser malgré la dimension réduite de traverse un conduit de drainage (11) des eaux de ruissellement au niveau de la dalle support (12) sensiblement suivant l'axe (13) de la voie.In addition, in the embodiment shown, the spacer (4) has in its central section a bending (16) downwards allowing, despite the reduced size of the cross member, to be drainage pipe (11) for runoff water at the level of the support slab (12) substantially along the axis (13) of the track.
Avantageusement, la dalle support (12) présente au niveau de sa face supérieure une pente (15) de part et d'autre de l'axe de la voie permettant de conduire les eaux de ruissellement vers le conduit de drainage (11).Advantageously, the support slab (12) present at its face higher a slope (15) on either side of the axis of the track allowing to lead the runoff to the drainage conduit (11).
De manière avantageuse, chaque blochet (2,3) comporte en partie inférieure une armature (9,10) en acier enrobée dans le corps en béton dudit blochet, ladite armature s'étendant à l'extérieur et latéralement à chaque blochet. Ces armatures (9,10) "sortantes" en partie inférieure de chaque blocjet permettent une liaison entre la traverse et la dalle support.Advantageously, each block (2,3) has in the lower part a steel frame (9,10) embedded in the concrete body of said block, said reinforcement extending outside and laterally at each block. These frames (9,10) "outgoing" in the lower part of each blocjetjet allow a connection between the cross member and the support slab.
Les rails (7,8) sont fixés aux blochets (2,3) au niveau des zones d'appui par l'intermédiaire de fixations d'attache de rails (14) traditionnelles, par exemple type STEDEF (NABLA, AP ou RN) ou de type PANDROL (FASCLIP) ou de type VOSSLOH.The rails (7,8) are fixed to the blocks (2,3) at the support zones by via traditional rail fasteners (14), for example type STEDEF (NABLA, AP or RN) or PANDROL type (FASCLIP) or VOSSLOH.
La traverse (1) comporte en outre un système de réglage d'altitude de voie avant coulage (non représenté).The crosspiece (1) further comprises an adjustment system track altitude before casting (not shown).
Avantageusement, les fixations d'attache de rail (14) et le système de réglage d'altitude sont protégés par un capot de protection d'attache (non représenté).Advantageously, the rail attachment fasteners (14) and the adjustment system are protected by an attachment protective cover (not shown).
