Abstract

The sleeper boot consists of an elastically deformable shell (1) to receive the sleeper (T). The shell is sloping inwards at the bottom and contains a sole (2) on which the sleeper rests. The lower part of the shell has recesses (10) in its inner wall which ensure a flexibility on compression even after the wall has been deformed as a result of hydrostatic pressure from the concrete bed (B). The boot's inner recesses are made in the wall to a height corresponding to the thickness of the sole plus the height (t) of a chamfered lower edge on the sleeper. At their lower ends, the recesses extend beneath the edge of the sole. In between the recesses the inner wall of the boot is made with a series of reinforcing ribs.

Description

La présente invention concerne un chausson pour traverse de voie de chemin de fer sans ballast. De telles voies sont utilisées notamment dans les tunnels.The present invention relates to a liner for a railroad cross member without ballast. Such routes are used in particular in tunnels.

De manière générale, et connue en soi, ce chausson qui est destiné à être immobilisé dans un lit de béton comprend, d'une part, une enveloppe élastiquement déformable recevant la traverse dont le pourtour inférieur est chanfreiné et, d'autre part, une semelle reposant sous la traverse dans le fond de ladite enveloppe. Le chausson confère à la voie une certaine élasticité dans des directions verticale et horizontale.In general, and known per se, this liner which is intended to be immobilized in a concrete bed comprises, on the one hand, an elastically deformable envelope receiving the crosspiece whose lower periphery is chamfered and, on the other hand, a sole resting under the cross member in the bottom of said envelope. The liner gives the track some elasticity in vertical and horizontal directions.

Cette semelle est réalisée avec un matériau élastique constitué le plus souvent d'un caoutchouc cellulaire.This sole is made with an elastic material usually made of cellular rubber.

Cependant, ce type de matériau peut avoir une géométrie qui évolue dans le temps en fonction des conditions d'entreposage.However, this type of material can have a geometry which changes over time depending on the storage conditions.

En particulier, lorsque les conditions favorables de stockage (température, taux d'humidité ...) ne sont pas respectées, la semelle subit un rétrécissement significatif.In particular, when the favorable storage conditions (temperature, humidity, etc.) are not respected, the sole undergoes significant shrinking.

Ce rétrécissement libère un volume périphérique qui reste inoccupé entre la traverse et les bords latéraux de la semelle à l'intérieur de l'enveloppe.This narrowing releases a peripheral volume which remains unoccupied between the cross-member and the lateral edges of the sole inside the envelope.

Or, lors de la réalisation du lit de béton pour immobiliser le chausson portant la traverse, la pression hydrostatique du béton encore liquide est suffisante pour déformer la paroi de l'enveloppe qui vient alors combler le vide existant à l'intérieur de l'enveloppe entre sa paroi interne et la semelle.However, when making the concrete bed to immobilize the liner carrying the cross member, the hydrostatic pressure of the still liquid concrete is sufficient to deform the wall of the envelope which then fills the void existing inside the envelope between its inner wall and the sole.

Dans cette situation, le pourtour inférieur de la traverse repose sur la paroi déformée de l'enveloppe et non plus sur la semelle.In this situation, the lower periphery of the crosspiece rests on the deformed wall of the envelope and no longer on the sole.

Il en résulte un "point dur", c'est-à-dire une zone rigide formant butée et bloquant le débattement vertical de la traverse.This results in a "hard point", that is to say a rigid zone forming a stop and blocking the vertical movement of the cross-member.

Par suite, le comportement vibratoire de la voie est perturbé, ce qui peut entraîner une détérioration de l'enveloppe et de la traverse.As a result, the vibratory behavior of the track is disturbed, which can lead to deterioration of the envelope and the cross-member.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.The present invention aims to solve these technical problems satisfactorily.

Ce but est atteint, conformément à l'invention, au moyen d'un chausson pour traverse de voie de chemin de fer sans ballast destiné à être immobilisé dans un lit de béton comprenant, d'une part, une enveloppe élastiquement déformable recevant ladite traverse, dont le pourtour inférieur est chanfreiné et, d'autre part, une semelle reposant sous la traverse dans le fond de ladite enveloppe caractérisé en ce que la partie inférieure de ladite enveloppe comporte, sur sa paroi interne, des évidements lui garantissant une souplesse en compression même après déformation de ladite paroi sous l'effet de la pression hydrostatique du lit de béton.This object is achieved, in accordance with the invention, by means of a boot for a railroad cross member without ballast intended to be immobilized in a concrete bed comprising, on the one hand, a elastically deformable envelope receiving said crosspiece, the lower periphery of which is chamfered and, on the other hand, a sole resting under the crosspiece in the bottom of said envelope characterized in that the lower part of said envelope comprises, on its internal wall, recesses guaranteeing it a flexibility in compression even after deformation of said wall under the effect of the hydrostatic pressure of the concrete bed.

Selon une caractéristique avantageuse, lesdits évidements sont réalisés sur une hauteur de la paroi interne correspondant à l'épaisseur de la semelle augmentée de la hauteur du chanfrein de la traverse.According to an advantageous characteristic, said recesses are made on a height of the internal wall corresponding to the thickness of the sole increased by the height of the chamfer of the crosspiece.

Selon une autre caractéristique, lesdits évidements sont réalisés à la fois sur la paroi latérale et sur le fond en se prolongeant sous le bord de ladite semelle.According to another characteristic, said recesses are made both on the side wall and on the bottom, extending under the edge of said sole.

Selon encore une autre caractéristique, la paroi interne comporte, entre les évidements, des éléments raidisseurs formés de surépaisseurs ou de bossages assurant le renfort de ladite paroi.According to yet another characteristic, the internal wall comprises, between the recesses, stiffening elements formed by thickenings or bosses ensuring the reinforcement of said wall.

De préférence, lesdits éléments raidisseurs sont réalisés dans l'angle inférieur de ladite enveloppe sur une hauteur correspondant à celle de la semelle.Preferably, said stiffening elements are produced in the lower corner of said envelope over a height corresponding to that of the sole.

Selon un premier mode de réalisation, lesdits évidements sont formés de cannelures.According to a first embodiment, said recesses are formed of grooves.

Selon un autre mode de réalisation, lesdits évidements sont formés d'alvéoles.According to another embodiment, said recesses are formed of cells.

Le chausson de l'invention permet d'assurer un fonctionnement statique et dynamique correct de la voie sans ballast même en présence d'une géométrie modifiée de la semelle.The liner of the invention makes it possible to ensure correct static and dynamic operation of the track without ballast even in the presence of a modified geometry of the sole.

En cas de déformation de l'enveloppe lors de la coulée du lit de béton, la traverse continue alors d'être supportée de façon élastique sans qu'il n'apparaisse de "point dur".In the event of deformation of the envelope during the pouring of the concrete bed, the cross-member then continues to be resiliently supported without any "hard point" appearing.

Les évidements réalisés sur la paroi interne de l'enveloppe permettent donc de garantir en toutes circonstances une souplesse en compression lors de l'enfoncement de la traverse.The recesses made on the internal wall of the envelope therefore make it possible to guarantee, in all circumstances, a flexibility in compression when the cross member is pressed.

L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels :The invention will be better understood on reading the description which follows, accompanied by the drawings in which:

La figure 1 représente une vue en coupe transversale d'un chausson traditionnel à l'état déformé, avec sa traverse.Figure 1 shows a cross-sectional view of a traditional liner in the deformed state, with its crosspiece.

La figure 2 représente une vue en coupe transversale d'un premier mode de réalisation du chausson de l'invention à l'état libre, sans traverse.2 shows a cross-sectional view of a first embodiment of the boot of the invention in the free state, without crosspiece.

La figure 3 représente une vue en coupe transversale du chausson de la figure 2 déformé et immobilisé dans le lit de béton, avec sa traverse.Figure 3 shows a cross-sectional view of the liner of Figure 2 deformed and immobilized in the concrete bed, with its cross.

La figure 4 représente une vue en coupe transversale d'une variante de réalisation du chausson de l'invention.Figure 4 shows a cross-sectional view of an alternative embodiment of the boot of the invention.

Le chausson représenté sur la figure 1 est un chausson traditionnel C pour traverse T de voie sans ballast. Ce chausson C est immobilisé dans un lit de béton B.The liner shown in Figure 1 is a traditional liner C for cross T track without ballast. This slipper C is immobilized in a concrete bed B.

Le chausson C comprend, d'une part, une enveloppe 1 élastiquement déformable recevant la traverse T et d'autre part une semelle 2 reposant sous la traverse T dans le fond 12 de l'enveloppe 1. Le pourtour inférieur de la traverse T est pourvu d'un chanfrein t. La paroi latérale interne de l'enveloppe 1 est pourvue de rainures périphériques 11 permettant d'apporter à la fois une élasticité longitudinale et transversale à la traverse T et une liberté de débattement vertical de la traverse au passage des charges roulantes sur la voie.The boot C comprises, on the one hand, an elastically deformable casing 1 receiving the cross member T and on the other hand a sole 2 resting under the cross member T in the bottom 12 of the casing 1. The lower periphery of the cross member T is provided with a chamfer t. The internal side wall of the casing 1 is provided with peripheral grooves 11 making it possible to provide both longitudinal and transverse elasticity to the cross-member T and freedom of vertical movement of the cross-member when passing rolling loads on the track.

Cependant, la semelle 2 peut subir un rétrécissement du fait de mauvaises conditions de stockage et ne plus remplir complètement le logement qui lui est destiné à la partie inférieure de l'enveloppe 1.However, the sole 2 can undergo narrowing due to poor storage conditions and no longer completely fill the housing which is intended for it at the lower part of the envelope 1.

Le volume périphérique libre qui subsiste alors autour de la semelle 1 est susceptible d'être comblé par la déformation de l'enveloppe 1 sous l'effet de la pression hydrostatique du béton liquide au moment de la coulée du lit B.The free peripheral volume which then remains around the sole 1 is likely to be filled by the deformation of the envelope 1 under the effect of the hydrostatic pressure of the liquid concrete at the time of the pouring of the bed B.

Cette déformation se traduit par un enfoncement de la zone angulaire de paroi latérale de l'enveloppe 1 qui vient alors en contact d'appui contre le chanfrein t de la traverse T comme représenté en traits mixtes et en traits pleins sur la figure 1.This deformation results in a depression of the angular zone of the lateral wall of the casing 1 which then comes into bearing contact against the chamfer t of the cross-member T as shown in dashed lines and in solid lines in FIG. 1.

Cette déformation crée une zone rigide formant butée pour le débattement vertical de la traverse T.This deformation creates a rigid zone forming a stop for the vertical travel of the cross member T.

Le chausson C de l'invention représenté sur la figure 2 à l'état libre, sans traverse, comporte une enveloppe 1 dont la partie inférieure est pourvue, sur sa paroi interne, d'évidements 10.The boot C of the invention shown in FIG. 2 in the free state, without a crosspiece, comprises an envelope 1, the lower part of which is provided, on its internal wall, with recesses 10.

Les évidements 10 sont destinés à garantir à l'enveloppe 1, une souplesse en compression même après déformation de la paroi sous l'effet de la pression hydrostatique du béton. Sur les figures 2 et 3, les évidements 10 sont réalisés sous forme de cannelures verticales dont la hauteur est au moins égale à l'épaisseur de la semelle 2 augmentée de la hauteur du chanfrein de la traverse T. De cette façon, les appuis de la traverse T sur la semelle 2 et sur l'enveloppe 1 sont uniformément répartis et assurent ainsi à la traverse un support élastique. Selon un autre mode de réalisation (non représenté), les évidements sont réalisés sous forme d'alvéoles.The recesses 10 are intended to guarantee the envelope 1, flexibility in compression even after deformation of the wall under the effect of the hydrostatic pressure of the concrete. In FIGS. 2 and 3, the recesses 10 are produced in the form of vertical grooves, the height of which is at least equal to the thickness of the sole 2 increased by the height of the chamfer of the cross member T. In this way, the supports of the cross member T on the sole 2 and on the casing 1 are uniformly distributed and thus provide the cross member with an elastic support. According to another embodiment (not shown), the recesses are made in the form of cells.

Les cannelures 10 se prolongent éventuellement sur la paroi interne du fond 12 de l'enveloppe 1 jusque sous le bord périphérique de la semelle 2.The grooves 10 possibly extend on the inner wall of the bottom 12 of the casing 1 as far as the peripheral edge of the sole 2.

De préférence, les extrémités 10a des cannelures sont biseautées pour faciliter leur démoulage lors de la fabrication du chausson C.Preferably, the ends 10a of the grooves are bevelled to facilitate their demolding during the manufacture of the boot C.

Chaque cannelure correspond à un affaiblissement de la paroi de l'enveloppe 1 et donc à une diminution de sa rigidité intrinsèque ou à une augmentation de sa souplesse.Each groove corresponds to a weakening of the wall of the envelope 1 and therefore to a decrease in its intrinsic rigidity or to an increase in its flexibility.

Le chausson représenté sur la figure 4 correspond à une variante de réalisation dans laquelle les évidements 10, réalisés ici sous forme de cannelures, sont séparés par des éléments raidisseurs 13 formés de bossage ou de surépaisseurs assurant le renfort de la paroi de l'enveloppe 1.The liner shown in FIG. 4 corresponds to an alternative embodiment in which the recesses 10, produced here in the form of grooves, are separated by stiffening elements 13 formed by bosses or thickeners ensuring the reinforcement of the wall of the envelope 1 .

Les bossages 13 font saillie dans l'angle inférieur vers l'intérieur de l'enveloppe 1 et permettent à la zone angulaire de liaison entre la paroi latérale et le fond 12 de mieux résister à la déformation sous pression hydrostatique externe. La hauteur des bossages 13 correspond sensiblement à celle de la semelle 2 à l'état libre de telle sorte que la face inférieure de la traverse T repose à la fois sur la semelle et, par son bord périphérique, sur la face supérieure du bossage 13.The bosses 13 project in the lower corner towards the inside of the casing 1 and allow the angular connection zone between the side wall and the bottom 12 to better resist deformation under external hydrostatic pressure. The height of the bosses 13 corresponds substantially to that of the sole 2 in the free state so that the underside of the cross-member T rests both on the sole and, by its peripheral edge, on the upper face of the boss 13 .

Dans ce cas, la semelle 2 sera réalisée initialement avec des dimensions sensiblement plus courtes que pour les autres modes de réalisation de telle sorte que, à l'état libre et en l'absence de déformation, il subsiste un léger jeu entre le bord périphérique de la semelle 2 et la face verticale du bossage 13.In this case, the sole 2 will be made initially with dimensions substantially shorter than for the other embodiments so that, in the free state and in the absence of deformation, there remains a slight clearance between the peripheral edge. of the sole 2 and the vertical face of the boss 13.
