La fig. 9 est une coupe partielle faisant ressortir un développement de l'invention.Fig. 9 is a partial section showing a development of the invention.

Ainsi que l'illustrent en particulier les fig. 1 et 2, le dispositif de voies ferrées comporte une forme ou dalle en béton 1 qui, dans la réalisation illustrée, présente en section sensiblement la forme d'un trapèze.As illustrated in particular in FIGS. 1 and 2, the track device has a shape or slab in concrete 1 which, in the illustrated embodiment, presents in section substantially the shape of a trapezoid.

La réalisation particulière de la forme 1 est décrite dans ce qui suit.The particular embodiment of form 1 is described in this following.

La forme 1 délimite deux tranchées longitudinales ou engravures 2, 3 dans lesquelles sont disposées des armatures successives 4. Les armatures 4 sont, par exemple, constituées par des cages métalliques successives disposées de façon équidistante dans les engravures 2, 3 et reliées entre elles par des fers de liaison longitudinaux par exemple ceux désignés par 5 à la fig. 4. Form 1 defines two longitudinal trenches or engravings 2, 3 in which successive reinforcements are arranged 4. The frames 4 are, for example, made up by successive metal cages arranged so equidistant in the engravings 2, 3 and interconnected by longitudinal connecting irons for example those designated by 5 in fig. 4.

La forme en béton 1 présente, sur ses deux côtés latéraux, des rebords surélevés 6, 6a qui bordent les tranchées ou engravures 2, 3. L'espace 7 délimité entre les rebords 6, 6a et entre les tranchées ou engravures 2, 3 sert à la mise en place de traverses 8 constituées par des profilés métalliques présentant en section la forme de la lettre U, le fond du profilé étant disposé à la partie supérieure.The concrete form 1 has, on its two lateral sides, raised edges 6, 6a which border the trenches or engravings 2, 3. The space 7 delimited between the edges 6, 6a and between the trenches or pits 2, 3 is used for setting place of sleepers 8 formed by metal profiles presenting in section the shape of the letter U, the bottom of the profile being disposed at the top.

Les traverses 8 sont disposées à égale distance les unes des autres par exemple tous les 180 cm et elles sont munies, dans leur fond, de taraudages ou d'écrous soudés 9 disposés avec précision. De même, les traverses présentent, à proximité des taraudages ou écrous soudés 9, des trous oblongs 10 dont le grand axe est parallèle à l'axe de chaque traverse.The crosspieces 8 are arranged at equal distance from each other others for example every 180 cm and they are provided, in their bottom, of threads or welded nuts 9 arranged with precision. Similarly, the sleepers have, near the welded threads or nuts 9, oblong holes 10, the major axis is parallel to the axis of each crosspiece.

Les trous oblongs 10 servent au passage de boulons 11 (fig. 2) pour le maintien de selles 12 destinées à supporter des rails 13 représentés sous la forme de rails à rainure pour le guidage de véhicules ferroviaires destinés à circuler sur une voie de circulation routière.The oblong holes 10 are used for the passage of bolts 11 (fig. 2) for the maintenance of saddles 12 intended to support rails 13 shown in the form of grooved rails for the guidance of railway vehicles intended to run on a road traffic lane.

Les selles 12 sont réalisées en matière composite ou autre (acier, fonte ...) ou sont munies d'une garniture 14 en matière élastique sur laquelle repose la semelle 13a des rails.The saddles 12 are made of composite or other material (steel, cast iron, etc.) or are fitted with a 14 in. elastic material on which the sole 13a of the rails.

Le taraudage ou écrou soudé 9 sert à la mise en place d'une vis 15 ou autre vérin amovible destiné à prendre appui contre le fond de la tranchée ou engravure 2 correspondante. En vissant plus ou moins la vis 15, la traverse 8 est soulevée et peut ainsi être réglée en hauteur avec une grande facilité puisque des vis 15 sont prévues en regard de chaque tranchée 2 comme le montre la fig. 3. Etant donné que le fond des tranchées ou engravures est en béton et présente une surface régulière, le réglage des vis est précis et fiable. The welded thread or nut 9 is used to install a screw 15 or other removable cylinder intended to bear against the bottom of the corresponding trench or channel 2. By screwing more or less the screw 15, the cross member 8 is raised and can thus be adjusted in height with great ease since screws 15 are provided opposite each trench 2 as shown in fig. 3. Since the bottom of the trenches or engravings is concrete and has a regular surface, screw adjustment is precise and reliable.

Les vis 15 servent aussi à la mise en place de cales de réglage 16 constituées par une plaquette carrée présentant un trou excentré 17 (fig. 3). Il est possible aussi que la cale de réglage présente une autre forme polygonale comme illustré en 16a, le trou 17a étant également excentré.The screws 15 are also used for fitting adjustment shims 16 constituted by a square plate presenting a eccentric hole 17 (fig. 3). It is also possible that the wedge has another polygonal shape as shown at 16a, the hole 17a also being eccentric.

Le taraudage ou l'écrou soudé 9 étant disposé avec précision, la mise en place de la cale de réglage enfilée sur la vis 15 permet de constituer une butée rendant possible d'assurer un écartement extrêmement précis des rails d'une voie en choisissant le côté de la cale qui convient pour un écartement déterminé, par exemple 141 cm, 141,5 cm, etc... En effet, la cale 16 ou 16a constitue une butée contre laquelle la selle 12 de chaque rail est appliquée. Il est possible aussi, pour ne pas tenir compte d'imperfections éventuelles des selles 12, de disposer les cales pour que ce soit directement le bord latéral de la semelle 13a du rail qui vienne en appui contre les cales.The thread or the welded nut 9 being arranged with precision, fitting the adjustment shim threaded on the screw 15 makes it possible to constitute a stop making it possible to ensure a extremely precise spacing of the rails of a track by choosing the side of the shim which is suitable for a determined spacing, for example 141 cm, 141.5 cm, etc. Indeed, the wedge 16 or 16a constitutes a stop against which the saddle 12 of each rail is applied. It is also possible, not to take into account possible imperfections in stool 12, arrange the shims so that it is directly on the side edge of the sole 13a of the rail which comes to bear against the wedges.

Pour être assuré que chaque rail est bien serré contre les cales de réglage portées par chaque traverse 8, il est prévu des douilles 18 dans la forme ou dalle 1 en béton, ces douilles servant à la mise en place de vérins de réglage 19 (fig. 3 et 4). Les vérins 19 sont retenus par un bord cambré 20 contre le rebord 6 et ils actionnent une partie mobile 21 constituant un mors d'étau par l'extrémité 21a qui assure la poussée du rail.To be sure that each rail is tight against adjustment shims carried by each cross member 8, it is provided sockets 18 in the form or concrete slab 1, these sockets used for fitting adjustment cylinders 19 (fig. 3 and 4). The cylinders 19 are retained by a curved edge 20 against the edge 6 and they actuate a movable part 21 constituting a vice jaw by the end 21a which ensures the rail push.

Ce qui précède montre que chaque traverse 8 constitue un gabarit perdu servant à la fois au centrage et au maintien des rails 13.The above shows that each cross member 8 constitutes a lost template used for both centering and holding rails 13.

La semelle 13a des rails est ensuite fixée à chaque selle 12 au moyen de lames 22 traversées par des tirefonds 23 vissés dans des gaines ou douilles 24 prenant appui contre le dessous du fond de la traverse 8.The sole 13a of the rails is then fixed to each saddle 12 by means of blades 22 crossed by screw bolts 23 screwed in sleeves or sockets 24 bearing against the underside from the bottom of the sleeper 8.

Après serrage des tirefonds 23, l'espace 7 de même que les tranchées ou engravures 2, 3 ainsi que l'intérieur de chaque traverse 8 sont remplis de béton amené par coulée et vibré in situ de façon à s'étendre jusqu'au niveau du dessus des rebords 6.After tightening the lag bolts 23, the space 7 as well as the trenches or engravings 2, 3 and the interior of each crosspiece 8 are filled with concrete brought in by casting and vibrated in located so as to extend to the level of the top of the ledges 6.

Les vis 15 formant vérins de réglage en hauteur peuvent être ensuite retirées en les dévissant et il en est de même des vérins de réglage 19 qui peuvent être réutilisés.The screws 15 forming height adjustment cylinders can be then removed by unscrewing them and the same goes for adjustment cylinders 19 which can be reused.

Après durcissement du béton coulé, une matière de remplissage 25, par exemple du béton ou de l'enrobé ou autre, est étendue jusqu'à affleurer le dessus du rail 13.After hardening of the poured concrete, a filling material 25, for example concrete or asphalt or other, is extended until it is flush with the top of the rail 13.

Pour la réalisation de la voie ferrée, on procède comme suit :For the construction of the railway, we proceed as follows:

On réalise tout d'abord un fond de forme 26 comme illustré par la fig. 5, puis on dispose des panneaux d'armature 27 maintenus à distance du sol du fond de forme par des pions 28 et des cales de retenue 29.We first make a bottom of form 26 as illustrated by fig. 5, then there are reinforcement panels 27 kept at a distance from the ground from the bottom of the form by pins 28 and retaining wedges 29.

La fig. 7 montre un pion 28 qui présente une rainure 28a pour le centrage d'un fer longitudinal ou transversal du panneau d'armature. De même, la fig. 9 montre une cale de retenue qui comporte une pince d'arrêt 30 pour un fer du panneau d'armature et un socle 31 présentant des lumières 32 pour la mise en place de broches d'ancrage non représentées.Fig. 7 shows a pin 28 which has a groove 28a for centering a longitudinal or transverse plate iron of frame. Likewise, fig. 9 shows a retaining wedge which includes a locking clip 30 for an iron of the reinforcement panel and a base 31 having lights 32 for placing in place of anchor pins not shown.

Les cales de retenue empêchent ainsi tout coulissement des panneaux d'armature par rapport au fond de forme.The retaining wedges thus prevent any sliding of the reinforcing panels with respect to the form bottom.

Après mise en place des panneaux d'armature 27, la forme ou dalle en béton 1 est coulée dans un coffrage glissant 33 porté par un véhicule 34 qui est déplacé sur des roues ou chenilles 35. Le véhicule 34 est normalement contrôlé par des organes permettant qu'il soit maintenu suivant une assiette pré-établie faisant que le dessus du fond de forme en béton ou dalle 1 présente la planéité recherchée et devant être respectée.After fitting the reinforcing panels 27, the shape or concrete slab 1 is poured into a sliding formwork 33 carried by a vehicle 34 which is moved on wheels or tracks 35. Vehicle 34 is normally controlled by bodies allowing it to be maintained on a plate pre-established making the top of the bottom form concrete or slab 1 has the desired flatness and must be respected.

La forme en béton 1 peut, le cas échéant, être complétée comme illustrée par la fig. 9 de façon à comporter, dans l'un ou l'autre de ses côtés, des tubulures 36 qui sont mises en place de façon connue en elle-même en même temps que le véhicule 34 portant le coffrage glissant 33 est déplacé le long du trajet que doit suivre ultérieurement la voie.Concrete form 1 can, if necessary, be completed as illustrated in fig. 9 so as to include, in one or the other of its sides, tubes 36 which are put in place in known manner at the same time as the vehicle 34 carrying the sliding formwork 33 is moved along of the route which the track must follow later.

Les cages d'armature 4 sont ensuite mises en place et des ferrures longitudinales non représentées sont ligaturées aux cages d'armature avant mise en place des traverses 8 puis des selles 12 fixées aux traverses comme expliqué dans ce qui précède.The reinforcement cages 4 are then put in place and longitudinal fittings not shown are tied to reinforcement cages before installation of the crosspieces 8 then of the saddles 12 fixed to the crosspieces as explained in what precedes.

Les rails 13 sont ensuite posés sur les selles puis les lames 22 sont elles-mêmes mises en place de même que les tirefonds 23 dont le serrage n'est effectué qu'après réglage de l'écartement des rails comme expliqué dans ce qui précède.The rails 13 are then placed on the saddles then the blades 22 are themselves in place as are the lag bolts 23, the tightening of which is carried out only after adjustment of the spacing rails as explained in the above.

La fig. 1 montre que des selles intermédiaires 12a peuvent être mises en place entre les traverses successives 8 formant gabarit de maintien.Fig. 1 shows that intermediate saddles 12a can be placed between the successive crosspieces 8 forming holding template.

Le réglage à la cote altimétrique de la voie est finalement réalisé au moyen des vis 15 puis le béton est déversé et vibré ou injecté et vibré pour remplir complètement l'espace 7 et les tranchées ou engravures longitudinales, ce qui a pour effet de noyer les armatures et d'ancrer les gaines ou douilles 24 qui assurent le maintien des tirefonds ou vis. The altimeter setting of the track is finally made using screws 15 then the concrete is poured out and vibrated or injected and vibrated to completely fill the space 7 and the longitudinal trenches or engravings, which has to drown the reinforcements and anchor the sheaths or sockets 24 which maintain the lag bolts or screws.

Les gaines ou douilles 24 étant seules ancrées dans le béton, il demeure possible, le cas échéant, de remplacer des tronçons de rail et des selles puisque les tirefonds peuvent toujours être dévissés puis revissés.The sleeves or sockets 24 being alone anchored in the concrete, it remains possible, if necessary, to replace sections rail and saddles since the lag bolts can always be unscrewed and then re-screwed.

L'invention n'est pas limitée aux exemples de réalisation, représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier elle peut être mise en oeuvre avec tous types de rails, tous types de selles, tous types d'attaches, etc.The invention is not limited to the exemplary embodiments, shown and described in detail, because various modifications can be made without departing from its scope. In particular it can be implemented with all types of rails, all types of saddles, all types of fasteners, etc.
