La bride présente un point d'appui intermédiaire (6) s'appuyant, lors de la rotation de la bride, sur une butée (38) ou sur une portée d'une selle métallique. Ce point d'appui intermédiaire assure la stabilité de la bride lors de sa rotation et dans sa position tendue et, dans le cas de l'utilisation d'une butée, maintient en place cette butée.Fixing flange consisting of a rod having a vertical rectilinear part (20) and a curved part forming a spring and the end (10) of which pinches the shoe (25) of the rail to be fixed after having been tensioned by rotation of the flange above a ramp (30), the lower end of the straight part being provided with a heel (2) which hooks onto a retaining surface (36) in the cross-member. The flange has an intermediate fulcrum (6) which rests, when the flange rotates, on a stop (38) or on a seat of a metal saddle.

Description

La présente invention a pour objet une bride de fixa­tion rapide d'un rail de chemin de fer sur des traver­ses ou des longrines en béton, bois, plastique ou métal, constituée d'une tige en acier ou plastique renforcé présentant une partie rectiligne verticale terminée par un talon excentré destiné à coopérer avec un moyen d'accrochage associé à la traverse ou à une selle métallique fixée sur la traverse et une partie recourbée formant ressort et dont l'extrémité est destinée à venir presser sur le patin du rail après rotation de la tige autour de sa partie verticale, rotation lors de laquelle ladite extrémité se déplace sur une rampe destinée à tendre la partie de la bride formant ressort et à la conduire sur le patin du rail.The subject of the present invention is a fastening flange for a railway rail on sleepers or beams made of concrete, wood, plastic or metal, consisting of a steel or reinforced plastic rod having a completed vertical straight part. by an eccentric heel intended to cooperate with a hooking means associated with the cross-member or with a metal saddle fixed on the cross-member and a curved part forming a spring and the end of which is intended to come to press on the rail pad after rotation of the rod around its vertical part, rotation during which said end moves on a ramp intended to tension the part of the flange forming a spring and to lead it onto the shoe of the rail.

Une bride de ce type est décrite dans la demande de brevet FR 2 608 182. Pour la fixation d'un rail sur une traverse en béton sans semelle métallique, la bride est utilisée avec une butée en matière plastique percée d'un trou que traverse la tige de la bride. Pour la fi­xation d'un rail sur une semelle métallique, cette bri­de est utilisée sans butée. Dans les deux cas, une fois que l'extrémité d'appui de la bride a été amemée sur le patin du rail, la tension sur la bride a tendance à faire basculer celle-ci, de telle sorte que sa tige rectiligne vient s'appuyer contre le bord du trou de la butée, respectivement de la semelle métallique. Si cette torsion n'est pas particulièrement gênante dans le cas d'une semelle métallique, elle présente par contre des inconvénients dans le cas d'une bride utili­sée avec une butée en matière plastique. Pour remédier à cet inconvénient, on a prévu de renforcer le bord su­ périeur du trou de la butée par un col. La butée a néanmoins tendance à se soulever par basculement autour de son bord extérieur et, d'autre part, au lieu d'exer­cer une pression verticale sur le béton de la traverse, elle exerce une pression transversale contre La paroi latérale de son logement dans le béton. Une telle sol­licitation du béton peut entraîner une fissuration du béton. La butée doit en outre supporter des efforts de compression et de torsion difficilement contrôlables.A flange of this type is described in patent application FR 2 608 182. For the fixing of a rail on a concrete sleeper without a metal sole, the flange is used with a plastic stopper pierced with a hole through which the flange rod. For fixing a rail on a metal base, this flange is used without stop. In both cases, once the support end of the flange has been moved to the rail pad, the tension on the flange tends to tilt it, so that its straight rod comes press against the edge of the hole of the stopper, respectively of the metal soleplate. If this twist is not particularly troublesome in the case of a metallic sole, it does have drawbacks on the other hand in the case of a flange used with a plastic stop. To remedy this drawback, provision has been made to reinforce the edge the hole in the stopper by a collar. The stop nevertheless tends to lift by tilting around its outer edge and, on the other hand, instead of exerting a vertical pressure on the concrete of the sleeper, it exerts a transverse pressure against the side wall of its housing in concrete. Such loading of the concrete can lead to cracking of the concrete. The stop must also withstand compression and torsion forces that are difficult to control.

La présente invention a pour but de réaliser une bride de fixation obviant aux inconvénients susmentionnés, tout en conservant la simplicité de la bride antérieu­re. Plus précisément, l'invention a pour but de réali­ser une bride de fixation exerçant en tout instant une pression verticale sur la butée, respectivement sur la semelle métallique et dont la tige ne bascule pas et ne vient pas s'appuyer contre le bord du trou de la butée, respectivement de la selle métallique.The object of the present invention is to produce a fixing flange which obviates the aforementioned drawbacks, while retaining the simplicity of the anterior flange. More specifically, the object of the invention is to produce a fixing flange which exerts a vertical pressure on the stopper, respectively on the metal soleplate, and the rod of which does not tilt and does not come to rest against the edge of the hole. of the stop, respectively of the metal saddle.

La bride selon l'invention est caractérisée par le fait que la partie recourbée de la tige de la bride présente une forme à la fois ondulée verticalement et enroulée autour de la partie verticale de la tige de telle sorte qu'elle présente un point d'appui intermédiaire consti­tué par le fond de la première ondulation et un point d'appui principal près de l'extrémité de la tige, ces deux points d'appui étant opposés relativement à la partie verticale, mais à des distances différentes de cette partie verticale, le rayon de giration du point d'appui intermédiaire étant sensiblement plus petit que le rayon de giration du point d'appui principal.The flange according to the invention is characterized in that the curved part of the rod of the flange has a shape which is both wavy vertically and wound around the vertical part of the rod so that it has a point of intermediate support formed by the bottom of the first corrugation and a main support point near the end of the rod, these two support points being opposite relatively to the vertical part, but at different distances from this vertical part, the radius of gyration of the intermediate fulcrum being substantially smaller than the radius of gyration of the main fulcrum.

La bride étant toujours en appui en deux points opposés relativement à la partie rectiligne de la bride, cette partie conserve une position verticale. Lorsque la bri­de est utilisée avec une butée, l'appui intermédiaire de la bride exerce sur la butée un effort vertical qui se traduit par une compression favorable du béton de la traverse dans la zone recevant les efforts latéraux du rail.The flange being always in abutment at two opposite points relative to the rectilinear part of the flange, this part maintains an upright position. When the flange is used with a stop, the intermediate support of the flange exerts on the stop a vertical force which results in a favorable compression of the concrete of the crosspiece in the area receiving the lateral forces of the rail.

La bride selon l'invention peut être livrée avec sa butée pour constituer un dispositif de fixation d'un rail sur une traverse en béton. L'invention a également pour objet un tel dispositif de fixation caractérisé par le fait que le périmètre de la face supérieure de la butée est compris entre le cercle de giration du point d'appui intermédiaire et le cercle de giration du point d'appui principal.The flange according to the invention can be delivered with its stop to constitute a device for fixing a rail on a concrete sleeper. The invention also relates to such a fixing device characterized in that the perimeter of the upper face of the stop is between the circle of gyration of the intermediate fulcrum and the circle of gyration of the main fulcrum .

L'invention a également pour objet une traverse de chemin de fer en béton équipée de tels dispositifs de fixation, cette traverse présentant, pour chaque rail, une creusure destinée à recevoir le rail et deux loge­ments attenant latéralement à cette creusure dans les­quels sont logées les butées des dispositifs de fixa­tion, le béton présentant une rampe s'étendant au moins entre le bord desdits logements opposé à la creusure destinée au rail et le bord de cette creusure, ces ram­pes constituant les rampes destinées à tendre les bri­des, et des moyens de retenue des tiges des brides noyés dans le béton.The invention also relates to a concrete railroad sleeper equipped with such fastening devices, this sleeper having, for each rail, a recess intended to receive the rail and two housings adjoining laterally to this recess in which are housed the abutments of the fixing devices, the concrete having a ramp extending at least between the edge of said housings opposite the recess intended for the rail and the edge of this recess, these ramps constituting the ramps intended to tighten the flanges, and means for retaining the flange rods embedded in the concrete.

L'invention a également pour objet une longrine en béton, particulièrement en béton armé, munie de supports métalliques, en forme d'arceau rectangulaire, sur lesquels les butées en matière synthétique sont fixées en atelier ou in situ.The invention also relates to a concrete sill, particularly of reinforced concrete, provided with metal supports, in the form of a rectangular arch, on which the plastic stops are fixed in the workshop or in situ.

L'invention a également pour objet une selle métallique pour traverse de chemin de fer équipée de brides selon la revendication 1, dont les tiges traversent des trous prévus dans la semelle et viennent s'accrocher sur des lamages dans lesquels débouchent lesdits trous, la selle présentant un logement destiné à recevoir le rail et, de chaque côté de ce logement, des rampes dont le prolongement coïncide avec le patin du rail, caracté­risée en ce que lesdites rampes ont la forme d'un che­min en arc de cercle dont le rayon moyen est égal au rayon de giration du point d'appui principal des bri­des. Le début de la rampe peut correspondre au point de fixation provisoire de la bride sur la semelle.The invention also relates to a metal saddle for a railway sleeper equipped with flanges according to claim 1, the rods of which pass through holes provided in the soleplate and come to hang on counterbores in which said holes open, the saddle having a housing intended to receive the rail and, on each side of this housing, ramps whose extension coincides with the shoe of the rail, characterized in that said ramps have the shape of a path in an arc of a circle whose mean radius is equal to the radius of gyration of the main support point of the flanges. The start of the ramp can correspond to the point of temporary fixing of the strap on the sole.

En outre, la bride de fixation est avantageusement munie d'une pièce profilée en matière synthétique ser­vant à boucher la partie du trou servant au passage du talon excentré d'accrochage de la bride et au guidage de sa partie verticale rectiligne lors de sa rotation.In addition, the fixing flange is advantageously provided with a profiled piece of synthetic material serving to plug the part of the hole serving for the passage of the eccentric heel for hooking the flange and for guiding its rectilinear vertical part during its rotation.

La bride représentée aux figures 1 à 3 est constituée d'une tige en acier de section circulaire présentant une partie rectiligne verticale 1 munie à sa base d'un talon 2 dirigé perpendiculairement à l'axe 3 de cette partie rectiligne. La tige d'acier présente une forme à la fois ondulée verticalement et enroulée autour de l'axe 3 de la partie verticale. La partie ondulée est constituée d'une courte partie ascendante 4 rectiligne en projection horizontale (figure 2) suivie d'une par­tie descendante 5 s'étendant sur un peu plus d'un demi-­cercle en projection horizontale, un premier point bas 6, constituant un point d'appui intermédiaire, suivi d'une partie ascendante 7 tout d'abord rectiligne en projection horizontale puis arrondie en passant par un point haut pour redescendre en une plus longue ondula­tion 8 de faible courbure se terminant au bas de l'on­dulation par une partie coudée 9 parallèle à la partie 7 en projection horizontale et constituant un point d'appui principal 10. Les points d'appui 6 et 10 pré­sentent des méplats destinés à réduire l'usure à la fois de la bride en ses points d'appui et des pièces sur lesquelles elle s'appuie. Vus en plan, c'est-à-dire dans la direction de l'axe 3 (figure 2), les points d'appui 6 et 10 sont diamètralement opposés relative­ment au milieu 11 du talon d'accrochage 2. Dans cette même vue, l'axe 3 de la partie rectiligne est situé sensiblement au milieu du triangle formé par les par­ties 7 et 8 de la tige et par la ligne droite reliant les points d'appui 6 et 10. On verra par la suite que cette disposition dirige les efforts de façon adéquate et assure une bonne stabilité de la bride. La partie rectiligne verticale 1 peut être plus ou moins longue selon le type de traverse sur laquelle elle est desti­née à être utilisée. On notera que le point d'appui principal 10 et le point d'appui intermédiaire 6 ne sont pas au même niveau, le point d'appui 10 étant environ 1cm plus bas que le point d'appui 6.The flange shown in Figures 1 to 3 consists of a steel rod of circular section having a vertical rectilinear part 1 provided at its base with a heel 2 directed perpendicular to the axis 3 of this rectilinear part. The steel rod has a shape that is both vertically wavy and wound around the axis 3 of the vertical part. The wavy part consists of a short ascending part 4 straight in horizontal projection (Figure 2) followed by a descending part 5 extending over a little more than a semicircle in horizontal projection, a first low point 6, constituting an intermediate fulcrum, followed by an ascending part 7 firstly rectilinear in horizontal projection then rounded by passing through a high point to descend into a longer undulation 8 of slight curvature ending at the bottom of the undulation by a bent part 9 parallel to the part 7 in horizontal projection and constituting a main support point 10. The support points 6 and 10 have flats intended to reduce wear both of the flange at its points d 'support and parts on which it is based. Seen in plan, that is to say in the direction of the axis 3 (FIG. 2), the support points 6 and 10 are diametrically opposite relatively to the middle 11 of the latching heel 2. In this same view, the axis 3 of the rectilinear part is located substantially in the middle of the triangle formed by the parts 7 and 8 of the rod and by the straight line connecting the support points 6 and 10. We will see later that this provision directs the efforts adequately and ensures good stability of the flange. The vertical rectilinear part 1 can be longer or shorter depending on the type of cross member on which it is intended to be used. It will be noted that the main support point 10 and the intermediate support point 6 are not at the same level, the support point 10 being approximately 1 cm lower than the support point 6.

L'utilisation de la bride de fixation représentée aux figures 1 à 3 pour la fixation d'un rail au moyen d'une selle métallique sera maintenant décrite en relation avec les figures 4 et 5.The use of the fixing flange shown in FIGS. 1 to 3 for fixing a rail by means of a metal saddle will now be described in relation to FIGS. 4 and 5.

Ces figures montrent une selle métallique 12 présentant une creusure 13 destinée à recevoir un rail 14 avec interposition d'une semelle élastique 15 en caoutchouc et de deux butées latérales 16 et 17 en matière plas­tique. La face inférieure 18 de la selle métallique 12 est légèrement inclinée car elle est destinée à être fixée sur une traverse en béton présentant un plan incliné. A cet effet la selle métallique 12 présente deux trous oblongs 18 et 19 destinés à recevoir des tirefonds venant se visser de préférence dans des douilles d'ancrage PLASTIRAIL (marque déposée) noyées dans le béton. De chaque côté de la creusure 9, la selle 12 présente deux portées planes 20 et 21 desti­nées à recevoir les brides de fixation. On se contente­ra de décrire en détail la portée 20, la portée 21 étant identique à la portée 20 mais située en tête-­bêche par rapport au rail. La portée 20 est plane et horizontale. Elle présente une partie de contour circu­laire 22 et une partie rectiligne 23 s'étendant le long de la creusure 13. Autour de la partie plane 20 s'étend, sur un quart de cercle, une rampe 24 en forme de chemin s'élevant progressivement en direction du rail 14. Le haut de cette rampe 20 est au niveau du bord du patin 25 du rail. Le milieu de la partie plane 20 est percé d'un trou 26 dont la forme est homologue de la forme du profil de la partie rectiligne 1 de la bride et du talon 2 dans la vue en plan de la figure 2, ceci avec le jeu nécessaire pour la libre introduction de la partie rectiligne 1 de la bride dans ce trou 26. Le trou 26 débouche dans un lamage 27 ménagé dans la face inférieure de la selle 12.These figures show a metal saddle 12 having a recess 13 intended to receive a rail 14 with the interposition of an elastic sole 15 of rubber and two lateral stops 16 and 17 made of plastic. The underside 18 of the metal saddle 12 is slightly inclined because it is intended to be fixed to a concrete cross member having an inclined plane. To this end, the metal saddle 12 has two oblong holes 18 and 19 intended to receive lag bolts which are preferably screwed into PLASTIRAIL (registered trademark) anchor sockets embedded in the concrete. On each side of the recess 9, the saddle 12 has two flat surfaces 20 and 21 intended to receive the fixing flanges. We will simply describe in detail the scope 20, the scope 21 being identical to the scope 20 but located upside down with respect to the rail. The range 20 is flat and horizontal. It has a part of circular contour 22 and a straight part 23 extending along the recess 13. Around the flat part 20 extends, over a quarter of a circle, a ramp 24 in the form of a path rising gradually. towards the rail 14. The top of this ramp 20 is at the edge of the pad 25 of the rail. The middle of the flat part 20 is pierced with a hole 26 whose shape is homologous to the shape of the profile of the straight part 1 of the strap and the heel 2 in the plan view of FIG. 2, this with the clearance necessary for the free introduction of the straight part 1 of the flange into this hole 26. The hole 26 opens into a countersink 27 formed in the underside of the saddle 12.

La bride de fixation est mise en place dans la position représentée en traits mixtes, c'est-à-dire dans une po­sition tournée de 180° autour de l'axe 3 relativement à la position représentée en traits forts. Dans cette po­sition, le talon d'accrochage 2 peut être introduit li­brement dans le trou 26. Le point d'appui principal 10 est dans une position 10′ en dehors de la rampe 24 et le talon d'accrochage 2 est très légèrement en dessous du lamage 27. Par une légère rotation de la bride, on amène simultanément le point d'appui principal 10 de la bride sur la rampe 24 et le talon 2 de la bride contre le lamage 27. Par une légère rotation supplémentaire de la bride on donne à celle-ci une légère tension, suffi­sante pour fixer provisoirement la bride sur la semelle métallique 12. Cette position est représentée en 10˝. La selle métallique peut ainsi être livrée munie des brides de fixation, les brides étant suffisamment main­tenues pour le transport et la mise en voie. Une fois la selle métallique fixée sur la traverse et le rail 14 posé dans son logement, chacune des brides de fixation est entraînée en rotation de telle sorte que son point d'appui principal 10 se déplace le long de la rampe 24 dont le rayon moyen est égal au rayon de giration du point d'appui 10 autour de l'axe 3. Quant au point d'ap­pui intermédiaire 6 il se déplace sur la surface plane horizontale 20. Finalement le point d'appui 10 vient s'appuyer sur le patin 25 du rail en exerçant une pres­sion de l'ordre de 10 à 12 kN. La bride s'appuie en outre par son point d'appui intermédiaire 6 sur la por­tée 20 de la selle en exerçant une traction verticale sur le talon d'accrochage 2 par l'intermédiaire de la partie rectiligne 1 de la bride. Le lamage 27 s'étend sur environ 1/2 cercle, de telle sorte que le talon vient buter contre l'extrémité de ce lamage, limitant ainsi la rotation de la bride de fixation. Il est pos­sible de prévoir un cran dans le lamage 27, de telle sorte que le talon d'accrochage 22 vienne se verrouil­ler dans ce lamage, empêchant ainsi l'enlèvement de la bride une fois le rail fixé. Sur la partie droite de la figure 5 on a désigné certaines parties correspondantes à la partie gauche par les mêmes références accompa­gnées du signe ′.The fixing flange is placed in the position shown in phantom, that is to say in a position rotated 180 ° around the axis 3 relative to the position shown in strong lines. In this position, the latching heel 2 can be freely introduced into the hole 26. The main fulcrum 10 is in a position 10 ′ outside of the ramp 24 and the latching heel 2 is very slightly below of the counterbore 27. By a slight rotation of the flange, the main fulcrum 10 of the flange is brought simultaneously on the ramp 24 and the heel 2 of the flange against the counterbore 27. By a slight additional rotation of the flange on gives it a slight tension, sufficient to temporarily fix the flange on the metal sole 12. This position is shown in 10˝. The metal saddle can thus be supplied fitted with fixing flanges, the flanges being sufficiently maintained for transport and setting up. Once the metal saddle is fixed on the cross member and the rail 14 is placed in its housing, each of the fixing flanges is rotated so that its main fulcrum 10 moves along the ramp 24 whose average radius is equal to the radius of gyration of the fulcrum 10 around the axis 3. As for the point d 'intermediate support 6 it moves on the horizontal flat surface 20. Finally, the support point 10 comes to bear on the pad 25 of the rail by exerting a pressure of the order of 10 to 12 kN. The flange is further supported by its intermediate fulcrum 6 on the seat 20 of the saddle by exerting a vertical pull on the latching heel 2 via the rectilinear part 1 of the flange. The counterbore 27 extends over approximately 1/2 circle, so that the heel abuts against the end of this counterbore, thereby limiting the rotation of the fixing flange. It is possible to provide a notch in the counterbore 27, so that the hooking heel 22 comes to lock in this counterbore, thus preventing the removal of the flange once the rail fixed. On the right part of FIG. 5, certain parts corresponding to the left part have been designated by the same references accompanied by the sign ′.

L'arc de rotation de la bride entre la position de mise en place et la position de fixation du rail ne doit pas nécessairement être de 180°, mais peut être inférieur ou supérieur à 180°.The arc of rotation of the flange between the position of installation and the position of fixing of the rail does not necessarily have to be 180 °, but can be less or more than 180 °.

On décrira maintenant à l'aide des figures 6 et 7, l'utilisation d'une bride de fixation selon l'invention pour la fixation d'un rail sur une traverse en béton 28 sans selle métallique. Cette traverse en béton peut être entièrement en béton ou constituée de deux blocs de béton reliés par une tige métallique comme illustré à la figure 9. Les figures 6 et 7 représentent seule­ ment une partie de la traverse, c'est-à-dire la partie correspondant à un rail. Pour chacun des rails, la tra­verse 28 présente une creusure 29 destinée à recevoir le rail. De chaque côté de cette creusure 29 la traver­se 28 présente deux rampes 30 et 31 descendant en s'éloignant de la creusure 29. De chaque côté de la creusure 29, la traverse 28 présente en outre deux lo­gements rectangulaires 32 et 33 dont le fond est au même niveau que le fond de la creusure 29 et qui commu­niquent avec cette creusure. Dans le béton sont noyées deux douilles 34 profilées, en matière synthétique en­tourées de métal. Ces douilles présentent la même cons­titution et la même forme extérieure que les gaines PLASTIRAIL (marque déposée) servant à la fixation de tirefond et décrites dans la demande de brevet français N° 88 12 185. Ces douilles 34 présentent à leur base un élargissement 35 formant un lamage 36 destiné à jouer un même rôle que le lamage 27 de la selle métallique. La douille 34 est représentée en perspective à la figu­re 8. Au-dessus de l'élargissement 35 la douille pré­sente un profil 37 homologue du profil du talon d'ac­crochage 2 de la bride de fixation. Dans cette exécu­tion, la bride de fixation présente une partie rectili­gne 1 sensiblement plus longue que la bride représentée aux figures 1 à 3, de manière à pouvoir s'accrocher au fond de la douille 34. Les douilles 34 débouchent bien entendu dans le fond des logements 32 et 33. La bride de fixation est montée avec une butée 38 en matière syn­thétique intercalée entre la partie courbe de la bride et le béton. Cette butée 38 à la forme d'un parallélé­pipède rectangulaire prolongé latéralement par une por­tée 39 en arc de cercle, portée qui prolonge la face supérieure plane de la butée et qui vient s'emboîter à redent sur le fond du logement 32. La forme générale de la butée 38 correspond à la forme du logement 32 dans lequel est logée cette butée. La butée 38 présente un trou profilé 40 permettant le passage du talon d'accro­chage 2 de la bride. Le périmètre de la butée 38 est compris entre le cercle de giration du point d'appui intermédiaire 6 et le cercle de giration du point d'ap­pui principal 10, de telle sorte que ce point d'appui principal 10 est toujours en dehors de la butée.We will now describe with the aid of Figures 6 and 7, the use of a fixing flange according to the invention for fixing a rail on a concrete cross member 28 without a metal saddle. This concrete sleeper can be entirely made of concrete or made up of two concrete blocks connected by a metal rod as illustrated in Figure 9. Figures 6 and 7 represent only part of the cross, that is to say the part corresponding to a rail. For each of the rails, the crosspiece 28 has a recess 29 intended to receive the rail. On each side of this recess 29 the cross member 28 has two ramps 30 and 31 descending away from the recess 29. On each side of the recess 29, the cross member 28 also has two rectangular housings 32 and 33 whose bottom is at the same level as the bottom of the recess 29 and which communicate with this recess. In the concrete are embedded two profiled sockets 34, of synthetic material surrounded by metal. These sockets have the same constitution and the same external shape as the PLASTIRAIL sheaths (registered trademark) used for fixing the lag screw and described in French patent application No. 88 12 185. These sockets 34 have at their base an enlargement 35 forming a counterbore 36 intended to play the same role as the counterbore 27 of the metal saddle. The sleeve 34 is shown in perspective in FIG. 8. Above the enlargement 35 the sleeve has a profile 37 which is homologous with the profile of the attachment heel 2 of the fixing flange. In this embodiment, the fixing flange has a straight portion 1 substantially longer than the flange shown in Figures 1 to 3, so as to be able to hang on the bottom of the socket 34. The sockets 34 of course open into the bottom of the housings 32 and 33. The fixing flange is mounted with a stop 38 in synthetic material interposed between the curved part of the flange and the concrete. This abutment 38 in the form of a rectangular parallelepiped extended laterally by a bearing 39 in an arc of a circle, bearing which extends the flat upper face of the abutment and which comes to be nested on the bottom of the housing 32. The general shape of the stop 38 corresponds to the shape of the housing 32 in which is housed this stop. The stop 38 has a profiled hole 40 allowing the passage of the hooking heel 2 of the flange. The perimeter of the abutment 38 is between the circle of gyration of the intermediate fulcrum 6 and the circle of gyration of the main fulcrum 10, so that this main fulcrum 10 is always outside the stop.

La bride de fixation, munie de sa butée 38, est tout d'abord introduite dans la douille 34 dans la position représentée en traits mixtes 6′, 10′, c'est-à-dire dans une position tournée de 180° relativement à la position représentée en traits forts. Dans cette position, le point d'appui principal 10′ est à 1 ou 2mm de la surfa­ce du béton sur la rampe 30. Par une légère rotation de la bride dans le sens des aiguilles d'une montre, le talon 2 de la bride vient s'engager sous le lamage 36. Par une légère rotation supplémentaire, le point d'ap­pui principal 10′ monte légèrement sur la rampe 30, ce qui a pour effet d'exercer une certaine tension sur la bride, tension qui assure la fixation provisoire de la bride sur la traverse en béton. Cette position de fixa­tion provisoire est, par exemple, la position 10˝. La traverse peut donc être équipée en usine des brides de fixation. Pour fixer le rail 14, il suffit de poursui­vre la rotation de la bride. Lors de cette rotation, le point d'appui principal 10 s'élève progressivement sur la rampe 30 du béton dont l'extrémité est au niveau du patin 25 du rail. Le point d'appui principal 10 vient s'appuyer, sous tension, sur le patin 25 avec une pres­sion de l'ordre de 10 à 12 kN. La rotation de la butée est limitée par la forme de l'élargissement 35 de la douille 34 qui constitue une butée limitant la rotation du talon d'accrochage 2. Lors de la rotation de la butée, le point d'appui intermédiaire 6 glisse sur la surface horizontale de la butée 38 en maintenant la partie rectiligne 1 de la bride en position verticale. La bride n'exerce aucune pression latérale sur le trou 40 de la butée 38. En position finale, le point d'appui intermédiaire 6 vient pincer la portée 39 de la butée sur le béton. La compression du béton dans cette zone est judicieuse car le béton peut ainsi mieux supporter les efforts transversaux dûs à la pression latérale exercée par le rail par l'intermédiaire de la butée 38.The fixing flange, provided with its stop 38, is firstly introduced into the socket 34 in the position shown in phantom 6 ′, 10 ′, that is to say in a position turned 180 ° relative to the position shown in strong lines. In this position, the main fulcrum 10 ′ is 1 or 2mm from the surface of the concrete on the ramp 30. By a slight rotation of the flange clockwise, heel 2 of the flange engages under the counterbore 36. By a slight additional rotation, the main fulcrum 10 ′ rises slightly on the ramp 30, which has the effect of exerting a certain tension on the flange, tension which ensures the fixing provisional flange on the concrete sleeper. This provisional fixing position is, for example, the position 10˝. The cross member can therefore be fitted with fixing flanges at the factory. To fix the rail 14, simply continue the rotation of the flange. During this rotation, the main fulcrum 10 gradually rises on the ramp 30 of the concrete, the end of which is at the level of the pad 25 of the rail. The main fulcrum 10 comes to bear, under tension, on the shoe 25 with a pressure of the order of 10 to 12 kN. The rotation of the stop is limited by the shape of the widening 35 of the sleeve 34 which constitutes a stop limiting the rotation of the latching heel 2. During the rotation of the stop, the intermediate fulcrum 6 slides on the horizontal surface of the stop 38 while maintaining the straight part 1 of the flange in the vertical position. The flange exerts no lateral pressure on the hole 40 of the stop 38. In the final position, the intermediate fulcrum 6 pinches the bearing 39 of the stop on the concrete. The compression of the concrete in this zone is judicious because the concrete can thus better withstand the transverse forces due to the lateral pressure exerted by the rail via the stop 38.

La douille 34 peut bien entendu être également pourvue d'un cran de verrouillage pour le talon 2 de la bride si l'on désire que celle-ci soit indémontable.The socket 34 can of course also be provided with a locking notch for the heel 2 of the flange if it is desired that the latter be removable.

Une traverse complète 28 est représentée à la figure 9. En traits mixtes, on a représenté une traverse mixte béton-acier. La traverse est équipée de quatre brides 1. Elle est livrée munie de ces brides dont la fixation provisoire est suffisante pour maintenir l'assemblage en place pendant le transport et la mise en voie.A complete cross 28 is shown in Figure 9. In phantom, there is shown a composite concrete-steel. The cross-member is fitted with four flanges 1. It is supplied fitted with these flanges, the provisional fixing of which is sufficient to keep the assembly in place during transport and setting up.

Le trou 26 dans la selle métallique et le trou 40 dans la butée 38 laissent pénétrer sable et salissure. Les figures 10 à 12 montrent un moyen de boucher ce trou tout en assurant un meilleur guidage de la partie ver­ticale 1 de la bride lors de sa rotation. Aux figures 10 et 11 on a représenté une partie de la bride repré­sentée aux figures 1 à 3. Sur la partie verticale 1, entre le talon 2 et la première partie courbe 4 de la bride, on a fixé un bouchon en matière plastique 41 remplissant l'espace vertical entre le talon 2 et la partie 4 et dont le profil remplit le profil du trou 26. Ce bouchon 41 est muni de deux bras recourbés 42 et 43 au moyen desquels le bouchon 41 est fixé par pince­ment sur la partie cylindrique 1 de la bride. Le bou­ chon 41 est de préférence légèrement plus grand que le trou 26 et creux comme le montre la coupe représentée à la figure 12 de manière à présenter une élasticité transversale, pour mieux boucher le trou 26. A la figu­re 10 on a également représenté en traits mixtes le ni­veau de la surface 20 de la selle métallique. Lors de l'introduction de la bride dans le trou 26, le bouchon 41 est engagé avec la partie rectiligne de la bride dans ce trou 26, l'ensemble venant occuper toute la section du trou 26. Lors de la rotation de la bride, le bouchon 41 reste en place servant de guide à la partie 1 de la bride. La figure 11 représente la bride après une certaine rotation de celle-ci relativement au bou­chon 41 retenu dans le trou 26.The hole 26 in the metal saddle and the hole 40 in the stop 38 allow sand and dirt to penetrate. Figures 10 to 12 show a means of plugging this hole while ensuring better guidance of the vertical part 1 of the flange during its rotation. In FIGS. 10 and 11 a part of the flange shown in FIGS. 1 to 3 is shown. On the vertical part 1, between the heel 2 and the first curved part 4 of the flange, a plastic plug 41 filling has been fixed. the vertical space between the heel 2 and the part 4 and whose profile fills the profile of the hole 26. This plug 41 is provided with two curved arms 42 and 43 by means of which the plug 41 is fixed by pinching on the cylindrical part 1 of the flange. The bou chon 41 is preferably slightly larger than the hole 26 and hollow as shown in the section shown in Figure 12 so as to have a transverse elasticity, to better plug the hole 26. In Figure 10 we have also shown in broken lines the level of the surface 20 of the metal saddle. When the flange is introduced into the hole 26, the plug 41 is engaged with the rectilinear part of the flange in this hole 26, the assembly coming to occupy the entire section of the hole 26. During the rotation of the flange, the plug 41 remains in place serving as a guide for part 1 of the flange. FIG. 11 shows the flange after a certain rotation of the latter relative to the plug 41 retained in the hole 26.

La bride représentée aux figures 6 et 7, ainsi qu'aux figures 13 à 17, peut bien entendu être équipée d'un bouchon analogue au bouchon 41, ne différant de celui-­ci que par sa longueur.The flange shown in Figures 6 and 7, as well as in Figures 13 to 17, can of course be fitted with a plug similar to the plug 41, differing from it only by its length.

La forme des ondulations de la bride, la forme de son talon et des trous pour le passage de ce talon peuvent bien entendu différer des formes représentées.The shape of the corrugations of the strap, the shape of its heel and the holes for the passage of this heel can of course differ from the shapes shown.

La butée 38 pourrait être plus grande et présenter une rampe analogue à la rampe 24 pour le point d'appui principal 10 de la bride.The stop 38 could be larger and have a ramp similar to the ramp 24 for the main fulcrum 10 of the flange.

Les rails sont parfois posés sur des longrines ou tra­verses en béton précontraint. La fabrication de longri­nes ou traverses en béton précontraint n'autorise pas la présence de creusures telles que les creusures pré­vues dans les traverses représentées aux figures 6 et 7. Il convient dans ce cas de recourir à une autre so­lution pour la fixation des butées en matière synthéti­ que. Les figures 13 à 16 illustrent une telle solution. Dans la longrine ou traverse 50 en béton précontraint, dont la surface est lisse, sont ancrés des supports mé­talliques 51 en forme d'arceau de profil rectangulaire dont les extrémités inférieures sont coudées pour assu­rer l'ancrage dans le béton. Sur chacun des arceaux 51 est montée une butée en matière synthétique 52. Paral­lèlement au profil de l'arceau 51, cette butée 52 pré­sente également un profil en forme d'arceau, comme ceci ressort de la figure 16. Plus précisément, la butée présente une face supérieure plane 53, un côté relati­vement épais 54 servant de butée de centrage pour le rail 14, deux côtés latéraux 55 à 56, plus minces, ser­vant au maintien de la butée sur l'arceau 51, le côté 56 étant muni d'un talon 57 dont la face supérieure est en forme de rampe 58 s'élevant en direction de la par­tie 54. Entre les parois 55 et 56 s'étend une paroi ho­rizontale 59 partant de la partie 54. La distance entre la paroi 59 et la partie 53 de la butée correspond à l'épaisseur du fer constituant l'arceau 51. La butée 52 est enfilée latéralement sur l'arceau 51 dans le sens de la flèche de la figure 16, l'arceau s'engageant en­tre la partie 53 et la paroi 59 et entre les parois 55 et 56. La butée 52 est munie d'un trou profilé 60 coïn­cidant avec un trou 61 de même profil de l'arceau 51, pour le passage de la bride. La partie supérieure de la partie 54 de la butée présente un chanfrein 62. Lorsque la butée 52 est monté sur son support 51, les côtés 55 et 56 et le talon 57 sont en contact avec la longrine 50. La butée 52 est tout d'abord équipée d'une bride identique aux brides des figures précédentes. Comme précédemment, le point d'appui principal 10 de la bride est ammené sur le début de la rampe 58 pour fixer pro­visoirement la bride. Après mise en place du rail 14 entre ces butées, mise en place facilitée par les chan­ freins 62, la bride est entraînée en rotation de telle sorte que le point d'appui principal 10 s'élève sur la rampe 58 à la hauteur du patin et du rail 14. Comme dans les exécutions précédentes, le périmètre de la face supérieure 53 de la butée est compris entre le cercle de giration du point d'appui intermédiaire 6 et le cercle de giration du point d'appui principal 10.The rails are sometimes laid on beams or crossbeams in prestressed concrete. The manufacture of prestressed concrete sleepers or sleepers does not allow the presence of hollows such as the hollows provided in the sleepers shown in Figures 6 and 7. In this case, another solution should be used for fixing the material stops synthesis than. Figures 13 to 16 illustrate such a solution. In the sill or cross member 50 of prestressed concrete, the surface of which is smooth, metal supports 51 are anchored in the form of a hoop of rectangular profile, the lower ends of which are bent to ensure anchoring in the concrete. A plastic stop 52 is mounted on each of the arches 51. Parallel to the profile of the arch 51, this stop 52 also has a profile in the form of an arch, as can be seen in FIG. 16. More precisely, the stop present a flat upper face 53, a relatively thick side 54 serving as a centering stop for the rail 14, two lateral sides 55 to 56, thinner, serving to hold the stop on the arch 51, the side 56 being provided with a heel 57 whose upper face is in the form of a ramp 58 rising in the direction of the part 54. Between the walls 55 and 56 extends a horizontal wall 59 starting from the part 54. The distance between the wall 59 and the part 53 of the stop corresponds to the thickness of the iron constituting the arch 51. The stop 52 is threaded laterally on the arch 51 in the direction of the arrow in FIG. 16, the arch engaging between the part 53 and the wall 59 and between the walls 55 and 56. The stop 52 e st provided with a profiled hole 60 coinciding with a hole 61 with the same profile of the arch 51, for the passage of the flange. The upper part of the part 54 of the stop has a chamfer 62. When the stop 52 is mounted on its support 51, the sides 55 and 56 and the heel 57 are in contact with the sill 50. The stop 52 is all First equipped with a flange identical to the flanges of the previous figures. As before, the main fulcrum 10 of the flange is brought to the start of the ramp 58 to temporarily fix the flange. After installation of the rail 14 between these stops, installation facilitated by the chan brakes 62, the flange is rotated so that the main fulcrum 10 rises on the ramp 58 at the height of the shoe and the rail 14. As in the previous embodiments, the perimeter of the upper face 53 of the stop is between the gyration circle of the intermediate fulcrum 6 and the gyration circle of the main fulcrum 10.

En disposant de butées présentant des épaisseurs diffé­rentes au niveau de la partie 54, il est possible, en choisissant l'épaisseur adéquate, de caler parfaitement le rail latéralement.By having stops having different thicknesses at the level of the part 54, it is possible, by choosing the appropriate thickness, to wedge the rail perfectly laterally.

La paroi mince 59 a en outre pour effet d'isoler élec­triquement la bride du support métallique 51.The thin wall 59 also has the effect of electrically isolating the flange from the metal support 51.

La butée décrite ci-dessus doit obligatoirement être montée sur son support métallique 51 avant la pose du rail. La figure 17 illustre une variante d'exécution permettant de fixer la butée isolante après la pose du rail. La butée étant une pièce d'usure, son remplace­ment peut dès lors être effectué sans déplacer le rail. La butée 63 diffère de la butée 52 en ce que la paroi 59 est remplacée par un rebord 64 parallèle à la partie 54′ correspondant à la partie 54, ce rebord 64 se ter­minant par une surépaisseur 65 en forme de crochet pré­sentant un chanfrein 66. La paroi 64 n'est pas reliée aux parois latérales correspondant aux parois 55 et 56 de la figure 16. La butée 63 est mise en place vertica­lement sur le support métallique 51, une simple pres­sion sur la butée écartant élastiquement la paroi 64 qui vient se fixer par clipage sur le support 51.The stop described above must be mounted on its metal support 51 before installing the rail. Figure 17 illustrates an alternative embodiment for fixing the insulating stop after the installation of the rail. The stop being a wearing part, its replacement can therefore be carried out without moving the rail. The stop 63 differs from the stop 52 in that the wall 59 is replaced by a rim 64 parallel to the part 54 ′ corresponding to the part 54, this rim 64 ending in an extra thickness 65 in the form of a hook having a chamfer 66. The wall 64 is not connected to the side walls corresponding to the walls 55 and 56 of FIG. 16. The stop 63 is placed vertically on the metal support 51, a simple pressure on the stop elastically spreading the wall 64 which comes fix by clipping on the support 51.

La butée 63 est avantageusement munie d'une languette souple 66 s'étendant latéralement de la partie 54′.The stop 63 is advantageously provided with a flexible tongue 66 extending laterally from the part 54 ′.

Comme ceci ressort du dessin, cette languette 66 est destinée à reposer sur le patin du rail 14. Elle est attachée assez haut sur la butée de telle sorte qu'elle peut suivre le patin du rail dans son mouvement descen­dant lors de sa fixation au moyen de la bride. La lan­guette 66 est finalement pincée entre le patin du rail et le point d'appui principal 10 de la bride. La lan­guette 66 protège le patin du rail contre l'effet de poinçonnement par frottement de la bride et isole élec­triquement la bride métallique du rail.As can be seen from the drawing, this tongue 66 is intended to rest on the shoe of the rail 14. It is attached fairly high on the stop so that it can follow the shoe of the rail in its downward movement when it is fixed by means of the flange. The tongue 66 is finally pinched between the shoe of the rail and the main fulcrum 10 of the flange. The tongue 66 protects the shoe of the rail against the effect of punching by friction of the flange and electrically insulates the metal flange from the rail.

La partie 54′ de la butée présente, dans sa partie in­férieure, un chanfrein 67 destiné à faciliter l'intro­duction de cette partie 54′ entre le support 51 et le patin du rail.The part 54 ′ of the stop has, in its lower part, a chamfer 67 intended to facilitate the introduction of this part 54 ′ between the support 51 and the shoe of the rail.

Dans une exécution simplifiée, le support 51 et la butée 52 pourraient être réalisés en une seule pièce en matériau ductile tel que fonte, fonte graphitée, allia­ge, matériau composite. La butée ainsi obtenue se pré­sente sous la forme d'une pièce ancrée dans le béton et présentant une partie en arceau au-dessus du béton, désirée à la fixation d'une bride telle que la bride décrite.In a simplified embodiment, the support 51 and the stop 52 could be made in a single piece of ductile material such as cast iron, graphite cast iron, alloy, composite material. The stop thus obtained is in the form of a part anchored in the concrete and having an arched portion above the concrete, desired for fixing a flange such as the flange described.
