Description

Dispositif* de fixation -de-rail -de -chemin -de-fer-sur-un-support • -en béton -ou -en -métal.Device * for fixing -from-rail -of-rail -of-iron-on-a-support • -in concrete -or -in-metal.
La présente invention concerne un dispositif de fixation de rail de chemin de fer sur un support en béton ou en métal.The present invention relates to a device for fixing a railway rail to a concrete or metal support.
Il s'agit plus particulièrement d'un dispositif de fixation prémontable sur un support, qu'il suffit ensuite, une fois le rail mis en place, de pivoter de 180° et de serrer pour le rendre opérationnel. Le caractère prémontable signifie que la fixation a été mise en place dès la fabrication du support ou traverse, et qu'elle se trouve dans une position telle que l'on pourra sur le chantier amener, déposer et positionner le rail sans démonter ou déplacer un quelconque élément. Le brevet Y0SSL0H DE 3243 895 décrit un dispositif de ce type qui présente toutefois un certain nombre d'inconvénients notamment en ce qui concerne le ressort de cette fixation qui est fait d'un fil d'acier en forme de boucle ouverte serrée par un tire-fond, ce qui oblige, en position prémontée, à serrer suffisamment le tire-fond pour maintenir en place le ressort sinon, lors des manutentions de la traverse, le ressort peut se détacher. Ce serrage qui n* est pas toujours correct complique la mécanisation de la pose. En effet, une fois le rail mis en place, il faut dévisser le tire-fond pour pivoter l'attache de 180°, puis le resserrer et le dévissage du tire-fond ne peut pas être fait à la main car le serrage initial a été fait volontairement assez fort pour retenir le ressort.It is more particularly a pre-assembled fixing device on a support, which it is then sufficient, once the rail is in place, to pivot 180 ° and to tighten to make it operational. The pre-assembled character means that the fixing was put in place as of the manufacture of the support or cross-member, and that it is in a position such that it will be possible on the site to bring, deposit and position the rail without dismantling or moving a any element. Patent Y0SSL0H DE 3243 895 describes a device of this type which however has a certain number of drawbacks in particular as regards the spring of this fixing which is made of a steel wire in the form of an open loop tightened by a puller -bottom, which requires, in the pre-assembled position, to sufficiently tighten the lag screw to hold the spring in place otherwise, when handling the cross member, the spring may come off. This tightening which is not always correct complicates the mechanization of the installation. Indeed, once the rail is in place, you have to unscrew the lag screw to pivot the fastener by 180 °, then tighten it and unscrewing the lag screw cannot be done by hand because the initial tightening has was intentionally strong enough to hold the spring.
Par ailleurs, dans ce type de fixation le ressort d'attache appuie une fois pivoté en position de serrage, directement sur le patin du rail. La pression de contact du métal du ressort sur le métal du rail est donc très élevée et provoque souvent un encochage du patin du rail par le ressort, en particulier si l'on utilise des semelles très élastiques sous le rail. Dans ce cas, il n'y a pas d'isolation électrique entre le ressort et le rail et il est alors nécessaire que l'ancrage de la fixation dans la traverse soit lui-même isolant.Furthermore, in this type of attachment, the attachment spring presses once pivoted in the clamping position, directly on the rail pad. The contact pressure of the spring metal on the metal of the rail is therefore very high and often causes a notching of the rail pad by the spring, in particular if very elastic soles are used under the rail. In this case, there is no electrical insulation between the spring and the rail and it is then necessary that the anchoring of the fixing in the crosspiece is itself insulating.
De plus, en position montée serrée sur le rail, la réaction verticale d'appui arrière du ressort se fait sur la butée. La zone d'application de cette réaction est plus proche du rail que ne l'est la zone d'application de l'effort transversal de la butée sur le béton de la traverse. La poussée transversale sur le béton, qui apparaît lors du passage d'un essieu à cause de l'obliquité de l'effort roue/rail, n'est donc pas compensée par un effort vertical et il apparaît un phénomène néfaste de poussée à vide. La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.In addition, in the tightly mounted position on the rail, the vertical reaction of the rear support of the spring takes place on the stop. The area of application of this reaction is closer to the rail than is the area of application of the transverse force of the stop on the concrete of the sleeper. The transverse thrust on the concrete, which appears during the passage of an axle because of the obliquity of the wheel / rail effort, is therefore not compensated by a vertical effort and there appears a harmful phenomenon of vacuum thrust . The present invention aims to solve these technical problems satisfactorily.
Ce but est atteint au moyen d'un dispositif de fixation d'un rail sur un support comprenant :This object is achieved by means of a device for fixing a rail on a support comprising:
- une lame ressort montée de manière pivotante sur le support au moyen d'un organe de serrage passant au travers de la lame par une ouverture, entre une position de transport permettant également la pose du rail et une position de travail assurant l'appui contre le rail et- a spring blade pivotally mounted on the support by means of a clamping member passing through the blade through an opening, between a transport position also allowing the installation of the rail and a working position ensuring the support against the rail and
- un intercalaire isolant disposé entre le support et la lame,caractérisé en ce que le dispositif comporte des moyens de blocage et des moyens de calage de ladite lame de telle sorte que la lame puisse être prémontée sur le support sans gêner la pose ultérieure du rail puis pivotée et maintenue en appui contre le rail en place. Selon une caractéristique de l'invention, lesdits moyens de blocage de la lame comprennent :- an insulating interlayer arranged between the support and the blade, characterized in that the device comprises locking means and means for wedging said blade so that the blade can be pre-assembled on the support without hindering the subsequent installation of the rail then pivoted and held in abutment against the rail in place. According to a characteristic of the invention, said blade blocking means comprise:
- au moins deux logements ménagés sur la face supérieure de l'intercalaire respectivement de part et d'autre de l'organe de serrage et destinés à recevoir respectivement en position de prémontage et en position de travail un bossage correspondant de la lame, etat least two housings formed on the upper face of the interlayer respectively on either side of the clamping member and intended to receive respectively in the pre-assembly position and in the working position a corresponding boss of the blade, and
- un ergot réalisé sur la face supérieure de l'intercalaire et destiné à venir s'insérer dans l'ouverture de la lame lorsque celle-ci est en position de travail ; la plus grande dimension de ladite ouverture étant supérieure au diamètre de l'organe de serrage.- A lug made on the upper face of the interlayer and intended to be inserted into the opening of the blade when the latter is in the working position; the largest dimension of said opening being greater than the diameter of the Tightening.
Selon une autre caractéristique, lesdits moyens de calage de la lame comprennent une butée isolante montée sur la face inférieure de la lame au niveau de son bord extérieur ; ladite butée étant destinée à venir respectivement en position de prémontage ou en position de travail de la lame, soit au contact du support et du bord extérieur de l'intercalaire, soit au contact du rail et du bord intérieur de l'intercalaire.According to another characteristic, said means for wedging the blade comprise an insulating stopper mounted on the underside of the blade at its outer edge; said stop being intended to come respectively in the pre-assembly position or in the working position of the blade, either in contact with the support and the outer edge of the interlayer, or in contact with the rail and the inner edge of the interlayer.
Selon. encore une autre caractéristique, ledit intercalaire comporte au niveau de sa partie extérieure un élément d'ancrage destiné à être inséré dans un logement correspondant du suppor .According to. yet another feature, said spacer comprises at its outer part an anchoring element intended to be inserted in a corresponding housing of the support.
Le dispositif de l'invention permet à la fois de répartir la pression de serrage, d'isoler électriquement la lame du rail et de retenir en position transversale la lame par rapport au rail, l'extrémité de la lame opposée à celle équipée de la butée isolante étant, quant à elle, toujours en appui sur l'une ou l'autre des extrémités de l'intercalaire isolant. Ainsi avec la présente invention, on a toujours une fixation prémontable mais la lame ressort est inséparable du support . Il en résulte qu'en position prémontée, il n'est pas nécessaire de serrer exagérément le tirefond (car la coopération des deux pièces isolantes est suffisante pour empêcher la rotation intempestive de la lame pendant les manutentions) . La lame ressort en position serrée est isolée mécaniquement et électriquement du rail et la réaction d'appui arrière de la lame se fait plus loin par rapport au rail que l'appui transversal sur le béton. Enfin, l'ancrage de la fixation bénéficiant de la présente invention n'a pas besoin d'être isolé électriquement par rapport à la traverse support, ce qui rend ce dispositif très économique.The device of the invention makes it possible both to distribute the clamping pressure, to electrically isolate the blade from the rail and to retain the blade in transverse position relative to the rail, the end of the blade opposite to that equipped with the insulating stop being, for its part, always in abutment on one or the other of the ends of the insulating interlayer. Thus with the present invention, there is always a pre-assembled fixing but the leaf spring is inseparable from the support. As a result, in the pre-assembled position, it is not necessary to over tighten the lag screw (because the cooperation of the two insulating parts is sufficient to prevent untimely rotation of the blade during handling). The leaf spring in the tight position is mechanically and electrically isolated from the rail and the rear support reaction of the blade takes place further from the rail than the transverse support on the concrete. Finally, the anchoring of the binding benefiting from the present invention does not need to be electrically isolated from the support cross member, which makes this device very economical.
La coopération des moyens de blocage de la lame avec les moyens de calage de ladite lame permet le prémontage du dispositif sur le support sans gêner la pose ultérieure du rail puis le pivotement et le maintien en appui de la lame contre le rail en place. Cette combinaison de moyens évite également tout déplacement et toute rotation intempestive de l'un quelconque des éléments du dispositif malgré les mouvements du rail au passage des trains.The cooperation of the blade blocking means with the wedging means of said blade allows the device to be pre-assembled on the support without hindering the subsequent installation of the rail, then the pivoting and the support of the blade against the rail in place. This combination of means also avoids all displacement and any untimely rotation of any of the elements of the device despite the movements of the rail when the trains pass.
L'invention sera mieux comprise à la lecture de la description ci-dessous illustrée par les dessins sur lesquels :The invention will be better understood on reading the description below illustrated by the drawings in which:

La butée 4 est clipsée sur le bord extérieur 51 de la lame ressort 5. Elle appuie par sa face inférieure 41 sur le support 1 et vient en butée contre le bord extérieur 33 de l'intercalaire 3 . Ainsi, l'ensemble lame ressort 5 / butée 4 ne peut pas se déplacer vers l'axe A de la table d'appui. Lorsque le rail est mis en place , il est posé sur la semelle 2 entre les faces 31 des intercalaires 3 des deux dispositifs de fixation en vis-à-vis.5 by an opening made in the form of the oblong hole 53 as well as through a round or oblong hole in the interlayer 3 and is screwed or sealed in the support 1. The stop 4 is clipped onto the outer edge 51 of the leaf spring 5. It presses by its lower face 41 on the support 1 and abuts against the outer edge 33 of the interlayer 3. Thus, the spring blade 5 / stop 4 assembly cannot move towards the axis A of the support table. When the rail is put in place, it is placed on the sole 2 between the faces 31 of the spacers 3 of the two fastening devices facing each other.
La butée 4 rendue solidaire de la lame 5, est donc mobile avec cette dernière dans le pivotement entre sa position de prémontage et de transport et sa position de travail. La face 31 de l'intercalaire 3 est plus proche de l'axe A que toute autre partie de la fixation. La tête 61 de l'organe de serrage 6 peut participer au guidage du rail lors de sa descente et de sa pose sur la semelle 2, ceci pour protéger le cas échéant le bord 31 de l'intercalaire 3. Une fois que le support ou traverse 1 a été fabriqué , on y dépose la semelle 2 puis l'intercalaire 3. Le bord 31 appuie de préférence sur le bord de la semelle 2 mais il peut aussi appuyer directement sur le fond du support 1.The stop 4 made integral with the blade 5, is therefore movable with the latter in the pivoting between its pre-assembly and transport position and its working position. The face 31 of the interlayer 3 is closer to the axis A than any other part of the binding. The head 61 of the clamping member 6 can participate in guiding the rail during its descent and its installation on the sole 2, this if necessary to protect the edge 31 of the interlayer 3. Once the support or cross-member 1 has been manufactured, the sole 2 is deposited there and then the interlayer 3. The edge 31 preferably presses on the edge of the sole 2 but it can also press directly on the bottom of the support 1.
L'intercalaire 3 possède éventuellement un élément d'ancrage tel qu'un petit téton 35 destiné à être inserré dans un logement 12 correspondant de la traverse 1 pour bien le maintenir en place.The interlayer 3 possibly has an anchoring element such as a small stud 35 intended to be inserted in a corresponding housing 12 of the cross member 1 to properly hold it in place.
La longueur de l'intercalaire 3 mesurée entre ses extrémités intérieure 31 et extérieure 33 est telle qu'en position prémoπtée la lame ressort 5 est bloquée en reposant par son extrémité comportant le bossage 52 dans le logement approprié 32 de l'intercalaire 3 tandis que son autre extrémité 51 munie de la butée mobile 4 est calée et retenue contre le bord extérieur 33 de l'intercalaire 3. De cette façon, il n'est pas nécessaire de serrer fortement la vis ou le boulon de l'organe de serrage 6 pour maintenir la lame 5 en place. Il peut même exister un léger jeu entre la tête ou l'écrou 61 de l'organe de serrage 6 et le dessus de la lame ressort 5 ; cette dernière étant bloquée en rotation et en translation verticale. La figure 2 est une vue de dessus de la figure 1 avec la trace 71 du bord du patin du rail. La trace 71 est très proche du bord intérieur 31 de l'intercalaire 3. La distance entre la trace 71 et le bord intérieur 31 est variable à la pose. En général, elle est comprise entre 0 et 3,5 mm pour accepter les tolérances de laminage du patin de rail.The length of the interlayer 3 measured between its inner 31 and outer 33 ends is such that in the premoπtée position the leaf spring 5 is blocked by resting at its end comprising the boss 52 in the appropriate housing 32 of the interlayer 3 while its other end 51 provided with the movable stop 4 is wedged and retained against the outer edge 33 of the interlayer 3. In this way, it is not necessary to tighten the screw or the bolt of the tightening member 6 to hold the blade 5 in place. There may even be a slight clearance between the head or the nut 61 of the clamping member 6 and the top of the leaf spring 5; the latter being blocked in rotation and in vertical translation. Figure 2 is a top view of Figure 1 with the trace 71 of the edge of the rail pad. The trace 71 is very close to the inner edge 31 of the interlayer 3. The distance between the trace 71 and the inner edge 31 is variable during installation. In general, it is between 0 and 3.5 mm to accept the rolling tolerances of the rail shoe.
La lame ressort 5 a une forme sensiblement trapézoïdale en vue de dessus. Ainsi, le clipsage de la butée 4 au moyen des ergots élastiques 41, 42, 43 et 44 est plus efficace. La butée 4, une fois clipsée sur le bord extérieur 51 de la lame 5, ne peut plus se séparer en s'éloignant de l'intercalaire 3 et ceci grâce à l'angle Q entre le bord extérieur 51 et le bord latéral de la lame qui est inférieur à 90°. La butée 4 ne peut pas non plus se rapprocher de l'intercalaire 3 car elle est en contact d'appui contre le bord extérieur dudit intercalaire 3 et il faudrait qu'il existe un jeu d'au moins 3 ou 4 mm entre le dessous de la tête 61 de l'organe de serrage 6 et le dessus de la lame 5 pour que la butée 4 puisse se soulever et échapper au bord extérieur 33 de l'intercalaire 3.The leaf spring 5 has a substantially trapezoidal shape when viewed from above. Thus, the clipping of the stop 4 by means of the elastic lugs 41, 42, 43 and 44 is more effective. The stop 4, once clipped to the outer edge 51 of the blade 5, can no longer separate away from the interlayer 3 and this thanks to the angle Q between the outer edge 51 and the lateral edge of the blade which is less than 90 °. The stop 4 can also not approach the interlayer 3 because it is in contact with support against the outer edge of said interlayer 3 and there should be a clearance of at least 3 or 4 mm between the bottom of the head 61 of the clamping member 6 and the top of the blade 5 so that the stop 4 can lift and escape the outer edge 33 of the interlayer 3.
Selon une variante de réalisation, la butée 4 est collée ou surmoulée à l'extrémité 51 de la lame 5.According to an alternative embodiment, the stop 4 is glued or molded to the end 51 of the blade 5.
La figure 3 représente une vue latérale de la fixation en position montée serrée sur le rail 7. Pour passer de la position prémontée de la figure 1 à la position de travail de la figure 3, les opérations sont les suivantes : - mise en place du rail 7 sur sa semelle 2 et entre les bords intérieurs 31 de chacun des intercalaires 3 propres à chaque fixation,FIG. 3 represents a side view of the fastening in the clamped mounted position on the rail 7. In order to pass from the pre-assembled position of FIG. 1 to the working position of FIG. 3, the operations are as follows: rail 7 on its sole 2 and between the inner edges 31 of each of the spacers 3 specific to each attachment,
- dévissage partiel de l'organe de serrage 6, la lame 5 restant toutefois prisonnière de cet ancrage grâce à son trou oblong, - pivotement par rotation de 180° de la lame 5.Pendant ce pivotement il y a déplacement transversal relatif du corps 62 de l'organe de serrage 6 par rapport au trou oblong 53 de la lame 5: le déplacement de la lame, en même temps que sa rotation, fait que le corps 62 de l'organe de serrage 6, qui était centré à une extrémité du trou oblong 53, se trouve, en fin de déplacement de la lame, centré à l'autre extrémité du trou oblong 53. La butée 4 mobile avec la lame ressort qui reste pendant toutes ces opérations clipsée au bord extérieur 51 de la lame 5, vient à la fois en appui sur le bord du patin du rail et contre le bord inrtérieur 31 de l'intercalaire 3,- partial unscrewing of the clamping member 6, the blade 5 remaining however captive of this anchoring thanks to its oblong hole, - pivoting by 180 ° rotation of the blade 5.During this pivoting there is relative transverse displacement of the body 62 of the clamping member 6 relative to the oblong hole 53 of the blade 5: the displacement of the blade, at the same time as its rotation, causes the body 62 of the clamping member 6, which was centered at one end of the oblong hole 53, is located, at the end of movement of the blade, centered at the other end of the oblong hole 53. The stop 4 movable with the leaf spring which remains during all these operations clipped to the outer edge 51 of the blade 5 , comes both to bear on the edge of the rail pad and against the inner edge 31 of the interlayer 3,
- serrage de la lame 5 grâce à l'organe de serrage 6 (tire-fond). La lame 5 étant un ressort, son galbe change pendant cette opération .L'extrémité de la lame 5 repose par le bossage 52 dans le logement en cuvette 38 aménagé sur la face supérieure de l'intercalaire 3 derrière l'organe de serrage 6 au niveau du bord extérieur 33.- clamping of the blade 5 thanks to the clamping member 6 (lag screw). The blade 5 being a spring, its curve changes during this operation. The end of the blade 5 rests by the boss 52 in the bowl housing 38 arranged on the upper face of the interlayer 3 behind the clamping member 6 at level of outer edge 33.
En position serrée sur le rail la distance entre l'une quelconque des extrémités du bord 51 de la lame 5 et le corps 62 de l'organe de serrage 6 est inférieure à -la distance entre ce même corps 62 et l'âme du rail 7. Cette condition est nécessaire pour permettre la rotation de 180° de la lame 5 lors de sa mise en place sur le rail par pivotement.In the clamped position on the rail, the distance between any one of the ends of the edge 51 of the blade 5 and the body 62 of the clamping member 6 is less than the distance between this same body 62 and the web of the rail. 7. This condition is necessary to allow the blade 5 to rotate 180 ° when it is placed on the rail by pivoting.
En fin de serrage le jeu J entre le dessous de la lame 5 et le dessus de l'intercalaire 3 sera compris entre 0 et 4 mm. Le choix de ce jeu J est fonction de l'élasticité en compression de la semelle 2 et du mode de serrage du tire-fond 6 .At the end of tightening, the clearance J between the bottom of the blade 5 and the top of the interlayer 3 will be between 0 and 4 mm. The choice of this clearance J is a function of the elasticity in compression of the sole 2 and the method of tightening the lag screw 6.
Lors d'un mouvement du rail, le jeu J varie car la lame élastique 5 a tendance à suivre le mouvement du rail.During a movement of the rail, the clearance J varies because the elastic blade 5 tends to follow the movement of the rail.
Les efforts latéraux communiqués par le rail provoquent une mise en appui du bord 71 du patin contre le bord intérieur 31 de l'intercalaire 3 qui retransmet ces efforts sur l'épaulement 11 du support 1 par sa face interne 37. La réaction verticale d'appui du bord arrière 52 de la lame 5 vient comprimer le support 1 et de ce fait diminue les effets néfastes de la poussée latérale de la face 37 de l'intercalaire 3 sur l'épaulement 11, poussée latérale qui se trouve ainsi située entre le rail et l'appui vertical arrière de la lame ressort.The lateral forces communicated by the rail cause the edge 71 of the pad to press against the inner edge 31 of the interlayer 3 which retransmits these forces on the shoulder 11 of the support 1 by its internal face 37. The vertical reaction of support of the rear edge 52 of the blade 5 compresses the support 1 and therefore reduces the harmful effects of the lateral thrust of the face 37 of the interlayer 3 on the shoulder 11, lateral thrust which is thus located between the rail and rear vertical support of the leaf spring.
Le rail 7 n'est en contact qu'avec des parties élastiques et isolantes, la semelle 2, la butée 4 et l'intercalaire 3. L'isolation électrique, très souvent requise entre le rail et son support, ne nécessite donc pas, avec la présente invention, un ancrage isolé électriquement du support.The rail 7 is only in contact with elastic and insulating parts, the sole 2, the stop 4 and the interlayer 3. The electrical insulation, very often required between the rail and its support, therefore does not require, with the present invention, an anchor electrically isolated from the support.
Bien que l'intercalaire 3 et la butée 4 doivent tous deux être isolants, ils ne sont pas sollicités mécaniquement de la même façon et il est préférable d'en tenir compte dans le choix des matériaux.Dans un mode de réalisation avantageux, on réalise l'intercalaire 3 et la semelle 2 en une seule pièce.Although the interlayer 3 and the stopper 4 must both be insulating, they are not mechanically stressed in the same way and it is preferable to take this into account in the choice of materials. In an advantageous embodiment, midsole 3 and sole 2 in one piece.
La figure 4 est une vue de dessus de la figure 3. Un ergot 34 est réalisé sur la face supérieure de l'intercalaire 3 et vient s'insérer dans l'ouverture en forme de trou oblong 53 de la lame lorsque celle-ci est en position de travail.Figure 4 is a top view of Figure 3. A lug 34 is formed on the upper face of the interlayer 3 and is inserted into the opening in the form of oblong hole 53 of the blade when the latter is in the working position.
La figure 5 représente le principe de clipsage de la butée 4 sur la lame 5 au moyen des ergots élastiques 41,42,43,44. Cette disposition n'est cependant pas limitative et, comme déjà signalé plus haut, on peut adhériser ou surmouler la butée 4 sur le bord 51 de la lame 5 .FIG. 5 represents the principle of clipping the stop 4 onto the blade 5 by means of the elastic lugs 41,42,43,44. This arrangement is not, however, limiting and, as already indicated above, the stop 4 can be adhered to or molded onto the edge 51 of the blade 5.
Les figures 6, 7 et 8 représentent la lame ressort 5 avec sa partie plane centrale, son bord extérieur 51 et son bossage 52. La figure 7 représente le nouveau galbe de la lame 5 après serrage. La forme générale de la lame 5 n'est pas limitative mais la présente invention impose une lame trapézoïdale en acier plat pourvue d'un trou suffisamment oblong pour pouvoir être mis de façon suffisamment décalée en position prémoπtée, afin de ne pas gêner la mise en place du rail. Une lame rectangulaire serait toutefois également possible si on adhérise ou si on surmoule la butée 4 sur ladite lame (l'angle o de la lame 5 n'étant plus un élément de retenue de la butée 4 sur le bord 51 de la lame 5) . Les figures 9 et 10 représentent l'intercalaire 3. Cet intercalaire 3 est pourvu éventuellement d'un élément d'ancrage tel qu'un téton 35. Le logement 32 est destiné à recevoir le bossage 52 de la lame 5 en position prémontée tandis que le logement 38 recevra le bossage 52 de la lame 5 en position de travail (appui contre le rail). Le trou 36 , ici représenté rond, laissera passer la tige 62 de l'organe de serrage 6. Ce trou 36 peut aussi être oblong voire débouchant sur le bord interne 31 pour faciliter la mise en place de l'intercalaire 3 lors de la fabrication du support 1. Généralement on prévoit un jeu entre la tige 61 et le trou 36 pour qu'en présence d'efforts latéraux, la tige 61 ne subisse aucun effort de flexion. Figures 6, 7 and 8 show the spring blade 5 with its central flat part, its outer edge 51 and its boss 52. Figure 7 shows the new curve of the blade 5 after tightening. The general shape of the blade 5 is not limiting, but the present invention requires a trapezoidal blade of flat steel provided with a hole which is sufficiently oblong to be able to be placed sufficiently offset in the premoπtée position, so as not to hinder the setting in rail place. A rectangular blade would however also be possible if the stop 4 is adhered to or overmolded on said blade (the angle o of the blade 5 is no longer a retaining element of the stop 4 on the edge 51 of the blade 5) . Figures 9 and 10 show the insert 3. This insert 3 is optionally provided with an anchoring element such as a stud 35. The housing 32 is intended to receive the boss 52 of the blade 5 in the pre-assembled position while the housing 38 will receive the boss 52 of the blade 5 in the working position (pressing against the rail). The hole 36, here shown round, will allow the rod 62 of the clamping member to pass through. This hole 36 may also be oblong or even open out onto the internal edge 31 to facilitate the positioning of the interlayer 3 during manufacture. of the support 1. Generally there is a clearance between the rod 61 and the hole 36 so that in the presence of lateral forces, the rod 61 does not undergo any bending force.
