Description

La présente invention est relative à un dispositif antibruit d'un rail pour des véhicules ferroviaires comportant une jaquette en matière élastique, ladite jaquette comprenant deux parties destinées à s'étendre de part et d'autre du rail, en particulier un rail pour tramways, d'une part, pour envelopper les deux flancs latéraux de ce rail, et, d'autre part, pour positionner ledit rail dans une rigole formée dans un matériau solide, en particulier du béton préfabriqué ou coulé, la matière élastique étant suffisamment rigide pour que les deux parties susdites puissent maintenir le rail en position lors du passage d'un véhicule sur le rail.The present invention relates to a noise-reducing device of a rail for railway vehicles comprising a jacket of elastic material, said jacket comprising two parts intended to extend on either side of the rail, in particular a trolley rail, on the one hand, for wrapping the two lateral flanks of this rail, and, on the other hand, for positioning said rail in a channel formed in a solid material, in particular prefabricated or cast concrete, the elastic material being sufficiently rigid for that the two aforesaid parts can maintain the rail in position during the passage of a vehicle on the rail.

De tels dispositifs font l'objet du brevet européen EP 0 854 234 B1 ainsi que de la demande de brevet internationale WO 2006/032684 A1 .Such devices are the subject of the patent European EP 0 854 234 B1 as well as the international patent application WO 2006/032684 A1 .

Ces dispositifs présentent, toutefois, l'inconvénient que s'il y a lieu de remplacer un bout de rail ceci nécessite un travail non négligeable et il faut détruire au moins partiellement les parties en matière élastique qui sont appliquées contre les flancs dudit rail, de sorte qu'elles ne sont pas réutilisables sans prendre des mesures additionnelles.These devices have, however, the disadvantage that if it is necessary to replace a piece of rail this requires a significant work and it is necessary to destroy at least partially the parts of elastic material which are applied against the sides of said rail, so that they are not reusable without taking additional measures.

Un des buts essentiels de la présente invention est de proposer une solution simple permettant de remédier à cet inconvénient important.One of the essential aims of the present invention is to propose a simple solution that makes it possible to remedy this important drawback.

A cet effet, le dispositif antibruit, suivant l'invention, comprend des moyens de fixation comportant un élément de serrage amovible permettant d'appliquer les deux parties susdites dans la rigole contre lesdits flancs latéraux du rail, de manière à fixer le rail dans la rigole et de libérer le rail dans cette dernière en éliminant l'élément de serrage.For this purpose, the anti-noise device, according to the invention, comprises fastening means comprising a removable clamping element for applying the two aforesaid parts in the channel against said lateral flanks of the rail, so as to fix the rail in the channel and release the rail in the latter by eliminating the clamping element.

Avantageusement, l'élément de serrage comprend une bande en matière élastique armée positionnée dans une fente parallèle aux flancs latéraux du rail prévue dans la rigole du côté d'une des parties élastiques opposé à celui orienté vers le rail d'une manière telle à pouvoir, d'une part, être retirée de la fente pour libérer le rail et, d'autre part, être forcée dans la fente pour fixer le rail.Advantageously, the clamping element comprises a band of reinforced elastic material positioned in a slot parallel to the lateral flanks of the rail provided in the channel on the side of one of the elastic parts opposite to that oriented towards the rail in such a way as to be able to on the one hand, be removed from the slot to release the rail and, on the other hand, be forced into the slot to secure the rail.

Suivant une forme de réalisation particulièrement avantageuse, la rigole présente des parois latérales sensiblement parallèles aux flancs latéraux du rail, un creux orienté vers ce dernier étant prévu dans chacune de ces parois, une des parties élastiques pouvant pénétrer dans le creux d'une de ces parois, l'élément de serrage pouvant s'engager dans le creux de l'autre paroi.According to a particularly advantageous embodiment, the channel has side walls substantially parallel to the lateral sides of the rail, a recess oriented towards the latter being provided in each of these walls, one of the parts elastics that can penetrate into the hollow of one of these walls, the clamping element being engageable in the hollow of the other wall.

Suivant une forme de réalisation particulière, le rail repose sur une semelle en matière élastique située sur le fond de la rigole.According to a particular embodiment, the rail rests on a sole of elastic material located on the bottom of the channel.

Dans les différentes figures les mêmes chiffres de référence concernent les mêmes éléments ou des éléments analogues.In the different figures, the same reference numerals refer to the same elements or similar elements.

D'une façon générale, l'invention concerne un dispositif antibruit des rails pour véhicules ferroviaires. Ce dispositif est logé avec le rail dans une rigole et comporte une jaquette en matière élastique constituée de deux parties destinées à s'étendre de part et d'autre contre les deux flancs latéraux d'un rail de manière à envelopper ces flancs. Cette matière élastique est suffisamment rigide et est par exemple formée de granules de caoutchouc liés entre eux par une résine élastomère, en particulier du polyuréthane. La jaquette est appliquée avec suffisamment de force contre les flancs du rail pour maintenir le rail en position lors du passage d'un véhicule sur ce rail.In general, the invention relates to a noise-reducing device for rails for railway vehicles. This device is housed with the rail in a channel and comprises a jacket of elastic material consisting of two parts intended to extend on either side against the two lateral sides of a rail so as to surround these flanks. This elastic material is sufficiently rigid and is for example formed of rubber granules bonded together by an elastomeric resin, in particular polyurethane. The jacket is applied with sufficient force against the sidewalls of the rail to maintain the rail in position when a vehicle passes on this rail.

Suivant l'invention, cette force est réalisée par des moyens de fixation comportant un élément de serrage amovible s'étendant sur toute la longueur du rail et appliqué fermement contre la face extérieure de la jaquette en direction des flancs du rail. Grâce au fait que l'élément de serrage est amovible celui-ci peut être enlevé de manière à permettre de libérer le rail dans la rigole et de la sortir facilement de cette dernière en maintenant la jaquette intacte. Ainsi, cette dernière peut être réutilisée lors de la pose d'un nouveau rail.According to the invention, this force is achieved by fastening means comprising a removable clamping element extending over the entire length of the rail and firmly applied against the outer face of the jacket in the direction of the flanks of the rail. Thanks to the fact that the clamping element is removable, it can be removed so as to allow the rail to be released into the channel and easily removed from the latter by keeping the jacket intact. Thus, the latter can be reused when laying a new rail.

Les figures 1 à 5 montrent une première forme de réalisation du dispositif antibruit, suivant l'invention.Figures 1 to 5 show a first embodiment of the noise protection device according to the invention.

Dans cette forme de réalisation, la jaquette est constituée de deux parties 1 et 2 séparées en matière élastique d'allure parallélépipédique droit s'étendant de part et d'autre d'un rails 3 contre les flancs latéraux 4 et 5 de ce dernier. Cette matière élastique est de la même nature que celle dont question dans le brevet européen EP 0 854 234 B1 ainsi que dans la demande de brevet internationale WO 2006/032684 A1 .In this embodiment, the jacket consists of two parts 1 and 2 separated elastic material of parallelepiped right look extending on either side of a rails 3 against the side flanks 4 and 5 of the latter. This elastic material is of the same nature as that referred to in the patent European EP 0 854 234 B1 as well as in the international patent application WO 2006/032684 A1 .

Cette rigole 6 est bordée de part et d'autre du rail 3 par des parois 7 et 8 s'étendant parallèlement aux flancs latéraux de ce dernier réalisées en une matière élastique dont la rigidité est, par exemple, quelque peu supérieure à celle dont est constituée la jaquette.This channel 6 is bordered on either side of the rail 3 by walls 7 and 8 extending parallel to the lateral sides of the latter made of an elastic material whose rigidity is, for example, somewhat greater than that of which is constituted the jacket.

Un élément de serrage 9 formé d'une bande en matière élastique, de préférence armée, est pressée entre la paroi 7 et la partie 1 en regard de la jaquette. Par conséquent, l'élément de serrage 9 est positionné dans une fente parallèle aux flancs latéraux du rail 3. La fente est prévue dans la rigole 6 du côté de la partie élastique 1 opposé à celui orienté vers le rail 3.A clamping element 9 formed of a strip of elastic material, preferably reinforced, is pressed between the wall 7 and the part 1 opposite the jacket. Consequently, the clamping element 9 is positioned in a slot parallel to the lateral flanks of the rail 3. The slot is provided in the channel 6 on the side of the elastic part 1 opposite that facing the rail 3.

Les parois 7 et 8 présentent chacune sur toute leur longueur un creux 10 et 11 orienté vers le rail 3. L'élément de serrage 9 est quelque peu bombé sur les faces latérales de sorte que cet élément 9 peut s'engager dans le creux 10 de la parois 7 et dans un creux correspondant 10' prévu dans la partie 1 de la jaquette.The walls 7 and 8 each have a recess 10 and 11 facing the rail 3 along their entire length. The clamping element 9 is somewhat curved on the lateral faces so that this element 9 can engage in the hollow 10 of the wall 7 and in a corresponding hollow 10 'provided in the part 1 of the jacket.

La partie élastique 2 pénètre dans le creux 11 de la paroi 8, sous l'action de l'élément de serrage 9 qui s'engage dans le creux 10 de la paroi 7.The elastic portion 2 enters the recess 11 of the wall 8, under the action of the clamping element 9 which engages in the recess 10 of the wall 7.

Le rail 3 repose sur une semelle en matière élastique rigide 12 située sur le fond de la rigole 6.The rail 3 rests on a sole of rigid elastic material 12 located on the bottom of the channel 6.

Les parois latérales 7 et 8 ainsi que la semelle 12 reposent de leur côté sur une succession de supports rigides 13 espacés prenant également appui contre la face extérieure 14 des parois 10 et 11 opposée à celle orientée vers le rail 3.The side walls 7 and 8 as well as the sole 12 rest on their side on a succession of rigid supports 13 spaced also bearing against the outer face 14 of the walls 10 and 11 opposite to that facing the rail 3.

Du béton 23 est alors coulé autour des parois 7 et 8 et la semelle 12 de manière à former la rigole 6 contenant le rail 3 et les deux parties 1 et 2 en matière élastique de la jaquette, en réservant de part et d'autre part du rail à des distances régulières des évidements 21.Concrete 23 is then cast around the walls 7 and 8 and the sole 12 so as to form the channel 6 containing the rail 3 and the two parts 1 and 2 of the elastic material of the jacket, reserving on both sides rail at regular distances from recesses 21.

Comme il est représenté dans la figure 1 les parties 1 et 2 de la jaquette et l'élément de serrage 9 s'étendent jusqu'à l'évidement 21 de sorte que dans cet évidement 21 le rail 3 et accessible. Les évidements 21 donnent, en particulier, accès au rail 3 permettant de le découper au moyen d'une scie et d'enlever le bout de rail entre deux évidements après avoir éliminé l'élément de serrage 9.As shown in Figure 1 the parts 1 and 2 of the jacket and the clamping member 9 extend to the recess 21 so that in this recess 21 the rail 3 and accessible. The recesses 21 give, in particular, access to the rail 3 for cutting it by means of a saw and removing the rail end between two recesses after eliminating the clamping element 9.

Pour éliminer l'élément de serrage 9 facilement, les évidements 21 donnent également accès à cet élément 9 de manière à pouvoir le pousser hors de la fente entre la paroi 7 et la partie 1 de la jaquette. Cet élément de serrage 9 est, en particulier, enlevé manuellement avec un matériel approprié, comme un pied-de-biche ou un levier, qui est inséré dans l'espace présente en dessous de l'élément de serrage 9 et accessible par l'évidement 21.To eliminate the clamping element 9 easily, the recesses 21 also provide access to this element 9 so as to be able to push it out of the slot between the wall 7 and the part 1 of the jacket. This clamping element 9 is, in particular, manually removed with appropriate material, such as a presser foot or a lever, which is inserted into the space below the clamping element 9 and accessible by the obviously 21.

La figure 6 concerne une deuxième forme de réalisation, suivant l'invention, qui se distingue essentiellement de la première par la nature des éléments de serrage 9.FIG. 6 relates to a second embodiment, according to the invention, which is essentially distinguished from the first by the nature of the clamping elements 9.

Dans cette forme de réalisation, les éléments de serrage 9 comprennent des profilés d'appui 15 en forme de Z enfilés sur des tiges filetées 16 verticales espacées fixées par leur extrémité inférieure sur un socle 17 sur lequel repose le rail 3 par l'intermédiaire d'une semelle 12.In this embodiment, the clamping elements 9 comprise Z-shaped bearing profiles 15 threaded onto spaced vertical threaded rods 16 secured by their lower end to a base 17 on which the rail 3 is supported by means of a sole 12.

Par un système d'écrou et de contre-écrou 18 les profilés 15 peuvent être soumis à un déplacement vers le bas et agir ainsi sur la surface supérieure des deux parties 1 et 2 de la jaquette pour les comprimer et les appliquer fermement contre les flancs 4 et 5 du rail 3.By means of a nut and counter nut system 18 the profiles 15 can be subjected to a downward movement and thus act on the upper surface of the two parts 1 and 2 of the jacket to compress them and apply them firmly against the sidewalls. 4 and 5 of the rail 3.

Un profilé de protection 19 en forme de L recouvre l'extrémité supérieure de la tige filetée 16 et est fixée sur cette dernière par une vis 20.An L-shaped protection profile 19 covers the upper end of the threaded rod 16 and is fixed thereto by a screw 20.

Du béton 23 est ensuite coulé autour de l'ensemble formé par le rail 3 et la jaquette 1, 2 jusqu'au niveau de la surface supérieure de cette dernière, de manière à former une rigole 6 contenant le rail 3 avec la jaquette 1,2.Concrete 23 is then cast around the assembly formed by the rail 3 and the jacket 1, 2 to the level of the upper surface thereof, so as to form a channel 6 containing the rail 3 with the jacket 1, 2.

Pour sortir le rail 3 de la rigole 6 avec la jaquette 1, 2, il suffit donc d'enlever les profilés 15 et 19 et de débloquer le système d'écrou et de contre-écrou 18.To remove the rail 3 from the channel 6 with the jacket 1, 2, it is sufficient to remove the profiles 15 and 19 and to unlock the nut and locknut system 18.

La figure 7 concerne une troisième forme de réalisation de l'invention qui se distingue essentiellement des précédentes formes de réalisation par le fait que la rigole 6 présente une section transversale trapézoïdale d'une manière telle à se rétrécir graduellement vers le fond de celle-ci et à présenter ainsi des parois planes inclinées 7 et 8.FIG. 7 relates to a third embodiment of the invention which differs essentially from the previous embodiments in that the channel 6 has a trapezoidal cross section in such a way as to gradually narrow towards the bottom thereof and thus to present inclined plane walls 7 and 8.

Les éléments de serrage 9 peuvent par exemple être du même genre que dans la deuxième forme de réalisation.The clamping elements 9 may for example be of the same kind as in the second embodiment.

Suivant une autre forme de réalisation, l'élément de serrage 9 peut être formé par un profilé plat, long et étroit 15' fixé par des vis 18 sur les bords 22 en béton délimitant la rigole 6 et faisant saillie par rapport à ces derniers en prenant appui sur la face supérieure de la jaquette. Par suite de la force exercée par le profilé 15' sur les parties 1 et 2 de la jaquette celles-ci sont poussées contre les flancs latéraux 4 et 5 du rail 3 et ce dernier est maintenu en position lors du passage d'un véhicule sur le rail.According to another embodiment, the clamping element 9 may be formed by a flat, long and narrow profile 15 'fixed by screws 18 on the concrete edges 22 delimiting the channel 6 and protruding relative to the latter. taking support on the upper face of the jacket. As a result of the force exerted by the section 15 'on the parts 1 and 2 of the jacket they are pushed against the lateral flanks 4 and 5 of the rail 3 and the latter is held in position during the passage of a vehicle on the rail.

Il est bien entendu que l'invention n'est pas limitée aux formes de réalisation décrites ci-dessus et montrées dans les figures annexées.It is understood that the invention is not limited to the embodiments described above and shown in the accompanying figures.

C'est ainsi que l'invention est applicable à tout type de rail pour véhicule sur rail.Thus the invention is applicable to any type of rail for rail vehicle.

Par ailleurs, les parties en matière élastique peuvent être de formes très variées. Il en est de même pour les autres parties constitutives du dispositif antibruit. C'est ainsi que l'élément de serrage peut être formé par une bande en matière élastique armée par une grille métallique s'étendant suivant le plan médian de la bande.Moreover, the parts made of elastic material can be of very varied shapes. It is the same for the other components of the noise protection device. Thus the clamping element can be formed by a band of elastic material armed with a metal grid extending along the median plane of the band.
