Abstract
Description
L'invention se rapporte à un procédé pour la construction d'une voie ferrée et en particulier à un procédé de construction d'une voie ferrée sur une dalle de béton dans lequel la dalle de béton est coulée autour d'éléments d'ancrage permettant la fixation de selles supportant les rails de la voie ferrée. L'invention concerne également une selle provisoire utilisée dans le procédé selon l'invention.The invention relates to a method for the construction of a railway line and particular to a method of constructing a railway on a concrete slab which the concrete slab is poured around anchoring elements allowing fixation of saddles supporting the tracks of the railway. The invention also relates to a temporary saddle used in the method according to the invention.
Il est connu actuellement pour les métros ou les tramways de procéder à la pose d'une voie ferrée sur une dalle de béton en amenant des rails directement prémontés sur des selles à l'endroit où la voie doit être posée, les rails étant maintenus en suspension dans leur position finale au moyen d'un portique avec les selles fixées au rail par des attaches. Une dalle de béton est ensuite coulée sous les rails jusqu'à hauteur des selles, ces dernières supportant des éléments d'ancrage constitués de tiges filetées traversant les selles et présentant une partie inférieure se trouvant noyée dans la dalle de béton. Une fois la prise du béton réalisée, les selles sont immobilisées définitivement sur la dalle de béton en serrant des écrous sur les tiges filetées, ces écrous venant prendre appui sur la face supérieure des selles.It is currently known for subways or trams to proceed with the laying of a railway on a concrete slab by bringing rails directly pre-assembled stool where the track is to be laid, the rails being kept suspension in their final position by means of a gantry with the saddles attached to the rail by fasteners. A concrete slab is then cast under the rails until stool height, the latter supporting anchoring elements consisting of rods threads passing through the saddles and having a lower part which is embedded in the concrete slab. Once the concrete has been taken, the stools are immobilized permanently on the concrete slab by tightening nuts on the threaded rods, these nuts coming to bear on the upper face of the saddles.
Dans un tel procédé de construction, il est nécessaire que les tiges filetées soient maintenus parfaitement perpendiculairement à la selle lors de la coulée du béton pour assurer un bon appui de la selle lors du serrage ultérieur des écrous sur les tiges filetées. Mais il est également nécessaire que les tiges filetées ne soient pas rendues rigidement solidaires de la selle afin que le serrage des écrous, après la prise du béton, provoque une mise sous tension de la partie des tiges filetées noyée dans le béton permettant d'obtenir une bonne tenue des tiges filetées dans la dalle de béton.In such a method of construction, it is necessary that the threaded rods are held perfectly perpendicular to the saddle when pouring concrete for ensure a good support of the saddle when tightening the nuts on the rods later threaded. But it is also necessary that the threaded rods are not rendered rigidly secured to the saddle so that the tightening of the nuts, after taking the concrete, causes tensioning of the part of the threaded rods embedded in the concrete to obtain a good hold of the threaded rods in the concrete slab.
Pour résoudre ce problème, il est connu actuellement d'utiliser des pièces élastiques ou des pièces fusibles qui maintiennent les tiges filetées sur la selle pendant la coulée du béton et qui permettent un déplacement des tiges filetées par rapport à la selle lors du serrage des écrous.To solve this problem, it is currently known to use elastic parts or fusible parts that hold the threaded rods on the saddle during casting concrete and which allow a displacement of the threaded rods with respect to the saddle during tightening the nuts.
Toutefois, de telles pièces élastiques ou pièces fusibles présentent l'inconvénient de ne pas assurer une bonne perpendicularité des tiges filetées sur la selle ce qui conduit à un mauvais appui des selles lors du serrage ultérieur des écrous. However, such elastic parts or fusible parts have the disadvantage of do not ensure a good perpendicularity of the threaded rods on the saddle which leads to a bad support of the saddles during the subsequent tightening of the nuts.
Aussi, un but de la présente invention est de proposer un procédé pour la réalisation d'une voie ferrée qui permette un positionnement précis, avec une bonne perpendicularité, d'éléments d'ancrage par rapport à la selle lors de la coulée du béton et qui permette d'obtenir des éléments d'ancrage qui soient indépendants des selles lors du serrage des écrous après la prise du béton.Also, an object of the present invention is to provide a method for carrying out a railway that allows precise positioning, with good perpendicularity, anchoring elements in relation to the saddle during casting of the concrete and which provides anchoring elements that are independent of the stool when tightening the nuts after setting the concrete.
A cet effet, l'invention a pour objet un procédé de construction d'une voie ferrée sur une dalle de béton dans lequel la dalle de béton est coulée autour d'éléments d'ancrage permettant la fixation de selles supportant les rails de la voie ferrée.For this purpose, the subject of the invention is a method of constructing a railway on a concrete slab in which the concrete slab is poured around elements anchoring device for fixing saddles supporting the tracks of the railway.

- keeping the pre-assembled rails in suspension on their final saddles above the place where the concrete slab is to be poured, each definitive saddle comprising a base under which is disposed a temporary saddle providing precise guidance of the anchoring elements of the final saddle,
- adjusting the position of the rails so as to precisely bring the underside of the temporary stool to where the final stools supporting the rails will have to rest,
- pouring the concrete slab up to the height of the temporary stool,

préhension de la selle provisoire 1.The
L'utilisation de la selle provisoire 1 précédemment décrite et le procédé de
construction selon l'invention vont maintenant être décrits en se référant aux figures
4 à 6.The use of the
Conformément à la figure 4, un portique 6 est utilisé pour amener deux rails 2 au-dessus
de l'emplacement où une dalle de béton 3 doit être coulée. Ces deux rails 2
sont suspendus par des pinces 61 reliées à une poutre motorisée 62, cette dernière
coulissant verticalement sur le portique 6 pour amener précisément les deux rails 2 à
l'emplacement désiré. Comme on peut le voir plus en détail sur les figures 5, 6 et 7,
les deux rails 2 sont reliés à des selles 5 par des attaches 9, ces selles 5 comportant de
manière classique une embase 51 constituée d'une plaque métallique sensiblement
pleine destinée à s'appuyer sur la dalle de béton 3 par l'intermédiaire d'une semelle
20, représentée sur la figure 7, en matériau résilient et avantageusement
électriquement isolant.According to Figure 4, a
Une selle provisoire 1 conforme à celle décrite précédemment est disposée sous
chacune des selles 5 de telle sorte que les douilles de guidage 13 supportées par la
selle provisoire 1 s'engagent dans des ouvertures ajustées 52 de l'embase 51, la face
inférieure de l'embase 51 venant prendre appui sur le sommet des écarteurs 14
supportés par la selle provisoire 1, un espace résultant alors entre la face inférieure de
l'embase 51 et la face supérieure de la plaque 11 de la selle provisoire 1. La selle
provisoire 1 est maintenue dans cette position sous la selle 5 par les éléments
d'ancrage de la selle 5 sur la dalle de béton 3 des tiges filetées 4 insérées dans les
douilles de guidage 13 recevant dans leur partie supérieure des écrous 18 de blocage,
ces tiges filetées 4 comportant un diamètre légèrement inférieur au diamètre de
l'alésage de la douille de guidage 13 et présentant un pincement local 41 sur lequel
repose une rondelle 17 prenant appui sur la face inférieure des douilles de guidage
13. Les tiges filetées 4 ainsi disposées comportent une partie débordant largement de
la face inférieure des selles provisoires 1 destinée à être noyée dans le béton.A
Préalablement à la coulée de la dalle de béton 3, la face inférieure des selles
provisoires 1 est enduite d'une huile de décoffrage et la poutre 62 du portique 6 est
pilotée de manière à amener la face inférieure des selles provisoires 1 à l'endroit où
devront être placées les surfaces d'appui des selles 5 destinés à supporter les rails 2
de la voie à construire.Prior to the pouring of the
Une dalle de béton 3, représentée en trait mixte sur la figure 4, est ensuite coulée par
gravité jusqu'à hauteur des selles provisoires 1 en venant noyer la partie des tiges
filetées 4 débordant sous la plaque 11. Une fois cette opération effectuée, la surface
supérieure du béton 3 est lissée de telle sorte que la surface du béton suive la pente
de la marche 15 en bordure de la selle provisoire 1, cette dernière indiquant
l'inclinaison que doit posséder la dalle de béton 3 par rapport à l'horizontal pour
assurer une évacuation correcte des eaux de ruissellement.A
Après un temps de séchage permettant la prise de la dalle de béton 3, les écrous 18
présents sur les tiges filetés 4 sont retirés et les rails 2 prémontés sur leurs selles 5
sont soulevés au moyen du portique 6. Les selles provisoires 1 accompagnées des
douilles de guidage 13 et des écarteurs 14 sont alors retirés, l'extraction des selles
provisoires 1 étant facilitée par la présence des poignées 16.After a drying time allowing the setting of the
Des entretoises isolantes électriquement 19, représentées sur la figure 7, sont alors
disposées à l'intérieur des ouvertures 52 des selles 5, ces entretoises isolantes 19
comportant un corps présentant une partie cylindrique, s'insérant dans les ouvertures
52, dont les diamètres intérieur et extérieur sont identiques aux diamètres intérieur et
extérieur des douilles de guidages 13, c'est à dire respectivement ajustés au diamètre
des ouvertures 52 et des tiges filetées 4. Ces entretoises 19 possèdent également une
collerette en partie supérieure sur laquelle vient s'appuyer les écrous de serrage, un
ressort, non représenté sur les figures, pouvant éventuellement être interposé entre
l'écrou et la collerette de l'entretoise 19, la hauteur de l'entretoise 19 étant telle qu'elle
ne déborde pas de la face inférieure de la selle 5 lorsqu'elle est insérée dans les
ouvertures 52.Electrically insulating

semelle 20 en matériau résilient sous la face inférieure de l'embase 51, cette semelle
20 possédant des trous au droit des tiges filetées. Une semelle supplémentaire 21,
simplement électriquement isolante, est avantageusement disposée sous la précédente
semelle 20, l'ensemble étant amené au contact de la dalle de béton 3 en faisant passer
les tiges filetées 4 débordant de la dalle de béton 3 au travers des semelles 20, 21 et
des alésages des entretoises isolantes 19 disposées dans les ouvertures 52 des
selles 5. Du fait de la présence de ces entretoises isolantes 19 aux dimensions
radiales similaires à celles des douilles de guidage 13 lors de cette opération, les
selles 5 sont alors positionnées automatiquement et précisément à leur emplacement
définitif.The
Les selles 5 sont ensuite immobilisées de manière classique à l'aide d'écrous 18
vissés sur les tiges filetées 4, ces derniers prenant appui sur la face supérieure de la
selle 5 par l'intermédiaire de la collerette de l'entretoise isolante 19.The
Un tel procédé de construction, par l'utilisation de selles provisoires conformes à l'invention, permet d'obtenir un positionnement précis des tiges filetées constituant les ancrages des selles et ceci avec une très bonne perpendicularité grâce à l'excellent guidage réalisé par les douilles de guidage. De plus, la mise en place des entretoises isolantes de gabarit équivalent aux douilles de guidage, après le retrait des selles provisoires, assure un positionnement précis des selles sur la dalle de béton sans procédure de réglage supplémentaire.Such a method of construction, by the use of temporary stools in accordance with the invention makes it possible to obtain precise positioning of the threaded rods constituting stool anchorages and this with a very good perpendicularity thanks to the excellent guiding carried out by the guide bushes. In addition, the installation of spacers insulating gauge equivalent to guiding sleeves, after removal of stool Provisional positioning of the saddles on the concrete slab without additional adjustment procedure.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given only as an example. Modifications are possible, particular from the point of view of the constitution of the various elements or by substitution technical equivalents, without departing from the scope of protection of the invention.
