Description

Domaine technique de l'Invention Technical field of the invention

L'invention est relative aux stations de téléphérique, notamment de télésiège ou télécabine, au montage et au démontage d'une telle station.The invention relates to cable car stations, including chairlift or gondola, assembly and disassembly of such a station.

État de la techniqueState of the art

Actuellement, la construction d'une station de téléphérique est généralement longue et peut demander plusieurs mois. En outre, la construction étant effectuée en plein air, celle-ci est soumise aux intempéries qui peuvent retarder le montage de la station, notamment pendant la période d'hiver. De manière générale, pour monter la station, on creuse une fosse et on réalise des supports en béton destinés à porter la partie supérieure de la station qui comprend entre autre la poulie d'entraînement du câble de traction transportant les véhicules. Les supports en béton sont coulés sur le lieu de montage de la station à l'aide de coffrages. Il est également nécessaire de couler au préalable une dalle en béton, nommée « béton de propreté », sur laquelle les supports sont réalisés. Mais il faut laisser sécher la dalle de béton et les supports pendant un temps assez long, sept jours au minimum, ce qui ralentit la construction de la station. Par ailleurs, le séchage est fortement influencé par les conditions météorologiques, ce qui ralentit encore le procédé de montage de la station. < page 1 bis >Currently, the construction of a cable car station is usually long and may take several months. In addition, the construction being carried out outdoors, it is subjected to bad weather that can delay the assembly of the station, especially during the winter period. In general, to mount the station, a pit is dug and concrete supports are made to carry the upper part of the station which includes, among other things, the traction sheave pulley carrying the vehicles. The concrete supports are poured on the site of assembly of the station by means of shuttering. It is also necessary to cast a concrete slab, called "concrete cleanliness", on which the supports are made. But the concrete slab and the supports must be allowed to dry for a long time, at least seven days, which slows down the construction of the station. Furthermore, the drying is strongly influenced by the weather conditions, which further slows the process of mounting the station. <page 1a>

Concernant le démontage des stations, il est possible de démonter la partie supérieure de la station, en vue de réutiliser les parties démontées pour un remontage ultérieur de la station sur un autre emplacement. Mais il n'existeRegarding the disassembly of the stations, it is possible to dismantle the upper part of the station, with a view to reusing the disassembled parts for a subsequent reassembly of the station to another location. But there is

La demande de brevet français FR 2255200 divulgue une station d'un télésiège, comprenant une ossature métallique de suspension d'une poulie. L'ossature métallique comprend deux palées triangulaires ayant chacune deux pieds en fer assemblés en V renversé. Les bases des pieds sont fixées à des massifs d'ancrage constitués par des blocs de béton.The French patent application FR 2255200 discloses a station of a chairlift, comprising a metal suspension frame of a pulley. The metal frame comprises two triangular piers each having two iron legs assembled in inverted V. The bases of the feet are attached to anchor blocks consisting of concrete blocks.

La demande de brevet français FR2329490 divulgue une gare de métro aérien comprenant un quai fixé à un seul appui et un plancher du quai constitué de béton léger. Par exemple, le plancher du quai est réalisé en éléments préfabriqués qui sont posés sur le bord des poutres longitudinales et des solives de plancher. En d'autres termes, le plancher peut être constitué de plaques de béton léger. Par ailleurs, les éléments de construction réalisés sous forme de construction légère sont livrés comme pièces terminées sur le chantier et peuvent y être rapidement montées, l'appui pouvant être transporté sur un camion normal.The French patent application FR2329490 discloses an overground railway station consisting of a single support dock and a light concrete pier platform. For example, the platform floor is made of prefabricated elements placed on the edge of longitudinal beams and floor joists. In other words, the floor may consist of light concrete slabs. In addition, construction elements made in the form of lightweight construction are delivered as completed parts on site and can be quickly mounted, the support can be transported on a normal truck.

Le document « Plus transparentes, plus légères, plus esthétiques » (Revue internationale des téléphériques, Bohmann, Wien, AT, n°3, 1er juin 1990, pages 16-20 ) divulgue un procédé de construction d'une gare qui peut être utilisée pour tous les systèmes débrayables. La gare comporte une structure porteuse uniforme qui repose sur deux piliers métalliques centraux supportant tous les rails et dispositifs de synchronisation. La gare comprend un pilier en béton à l'arrière.The document "More transparent, lighter, more aesthetic" (International Review of Cableways, Bohmann, Wien, AT, No. 3, 1 June 1990, pages 16-20 ) discloses a method of constructing a station that can be used for all disengageable systems. The station has a uniform supporting structure that rests on two central metal pillars supporting all the rails and synchronization devices. The station includes a concrete pillar at the back.

Mais ces documents ne permettent pas un montage suffisamment rapide d'une station de téléphérique.But these documents do not allow a sufficiently fast assembly of a cable car station.

pas de procédé de démontage des supports en vu de leur réutilisation. Actuellement, on détruit les supports sur place, ou on les enterre.no method of dismounting the media for reuse. Currently, the media are destroyed on site or buried.

Objet de l'invention Object of the invention

Un objet de l'invention consiste à pallier les inconvénients cités ci-avant, et en particulier à fournir un procédé de montage d'une station de téléphérique qui soit rapide et qui garantisse un montage d'une station robuste remplissant les normes de sécurité exigées.An object of the invention is to overcome the drawbacks mentioned above, and in particular to provide a method of mounting a cable car station which is fast and which guarantees a mounting of a robust station meeting the required safety standards .

Un autre objet de l'invention est de fournir un procédé de démontage d'une station qui permette une réutilisation des différents éléments de la station démontés pour un remontage de la station sur un autre emplacement.Another object of the invention is to provide a method of disassembly of a station that allows reuse of the various elements of the dismantled station for reassembly of the station to another location.

Un autre objet de l'invention est de fournir une station de téléphérique démontable en vu de remonter la station sur un nouvel emplacement.Another object of the invention is to provide a dismountable cable car station in view of going up the station to a new location.

Selon un aspect de l'invention, il est proposé un procédé de montage d'une station de téléphérique, notamment de télésiège ou télécabine.According to one aspect of the invention, there is provided a method of mounting a cable car station, including chairlift or gondola.

Le procédé comprend :

  • une étape de préfabrication dans laquelle on réalise au moins un support préfabriqué en béton destiné à soutenir une partie supérieure de la station, l'étape de préfabrication étant effectuée dans une zone de fabrication ;
  • une étape de transport de chaque support préfabriqué depuis la zone de fabrication vers une zone de montage distincte de la zone de fabrication ; et
  • une étape de montage de la station comprenant une pose de chaque support préfabriqué en un endroit prédéterminé du sol délimitant la zone de montage.
The method comprises:
  • a prefabrication step in which at least one prefabricated concrete support is made to support an upper part of the station, the prefabrication step being carried out in a manufacturing zone;
  • a step of transporting each prefabricated support from the manufacturing area to a mounting area separate from the manufacturing area; and
  • a step of mounting the station comprising a laying of each prefabricated support at a predetermined location of the ground delimiting the mounting area.

Ainsi, on fournit un procédé plus rapide et qui est moins soumis aux conditions météorologiques. En effet, grâce à une étape de préfabrication des supports effectuée avant l'étape de montage de la station, il n'est plus nécessaire de couler les supports sur place. En outre, on n'a plus besoin d'attendre le séchage sur place des supports. En particulier, l'étape de préfabrication des supports peut ne plus être soumise aux intempéries car les supports sont réalisés dans une zone dédiée à la fabrication des pièces en béton, telle une usine ou un local fermé. On peut en outre obtenir un meilleur contrôle de la fabrication des supports pour garantir une meilleure robustesse à la station.Thus, a faster process is provided which is less subject to weather conditions. Indeed, thanks to a prefabrication stage supports carried out before the stage of mounting of the station, it is no longer necessary to cast the media in place. In addition, it is no longer necessary to wait for the in situ drying of the supports. In particular, the step of prefabrication of the supports can no longer be subjected to bad weather because the supports are made in an area dedicated to the manufacture of concrete parts, such as a factory or a closed room. In addition, it is possible to obtain better control of the manufacture of the supports to guarantee greater robustness at the station.

Description détailléedetailed description

Sur la figure 1, on a représenté schématiquement une station 1 de téléphérique, notamment de télésiège ou télécabine, démontable. La station 1 peut également être destinée à un téléski ou un télécordes (appelé également fil-neiges). La station 1 comprend une partie supérieure 2 et une partie inférieure 3 sur laquelle repose la partie supérieure 2. La partie supérieure 2 comporte un toit 4, une charpente 5 pour supporter le toit 4, et une poulie 6 d'entraînement d'un câble tracteur 7 sur lequel sont accrochés des véhicules, tels des sièges ou cabines, pour le transport de personnes ou autres. La station 1 peut être une station d'embarquement ou de débarquement des personnes. On a représenté sur la figure 1, un mode de réalisation d'une station 1 d'embarquement de personnes. La station 1 d'embarquement comporte un moteur 8 monté sur la charpente 5, pour entraîner la poulie 6, via notamment un arbre moteur 9. La partie inférieure 3 de la station 1 comporte, quant à elle, au moins un support préfabriqué 10, 11 destiné à soutenir la partie supérieure 2 de la station 1 et au moins un pylône 12, 13, chaque pylône 12, 13 étant monté entre un support préfabriqué 10, 11 et la charpente 5 de façon à surélever la partie supérieure 2 de la station 1. Dans l'exemple illustré sur la figure 1, la station 1 comporte deux supports préfabriqués 10, 11 et deux pylônes 12, 13. Selon d'autres modes de réalisation, la station 1 peut comporter un ou plusieurs supports préfabriqués et un ou plusieurs pylônes.On the figure 1 schematically shown a station 1 cable car, including chairlift or gondola, removable. The station 1 can also be intended for a ski lift or a telecord (also called snow-wire). The station 1 comprises an upper part 2 and a lower part 3 on which the upper part 2 rests. The upper part 2 comprises a roof 4, a frame 5 to support the roof 4, and a pulley 6 for driving a cable. tractor 7 on which are hung vehicles, such as seats or cabins, for the transport of persons or others. Station 1 can be a boarding or disembarking station. We have shown on the figure 1 , an embodiment of a station 1 boarding people. The boarding station 1 comprises a motor 8 mounted on the frame 5, for driving the pulley 6, in particular via a driving shaft 9. The lower part 3 of the station 1 comprises, in turn, at least one prefabricated support 10, 11 for supporting the upper part 2 of the station 1 and at least one pylon 12, 13, each pylon 12, 13 being mounted between a prefabricated support 10, 11 and the frame 5 so as to raise the upper part 2 of the station 1. In the example shown on the figure 1 the station 1 comprises two prefabricated supports 10, 11 and two pylons 12, 13. According to other embodiments, the station 1 may comprise one or more prefabricated supports and one or more towers.

La structure de la station 1 comprenant les parties supérieure 2 et inférieure 3, est montée sur une zone de montage 14. Sur la figure 1, on a représenté deux lignes en pointillés référencées 15, 16, et la zone de montage 14 est comprise entre les deux lignes 15, 16.The structure of the station 1 comprising the upper 2 and lower 3 parts, is mounted on a mounting zone 14. On the figure 1 two dashed lines referenced 15, 16 are shown, and the mounting zone 14 is between the two lines 15, 16.

De façon générale, les supports préfabriqués 10, 11 sont posés en un endroit prédéterminé du sol délimitant la zone de montage 14. Le sol peut être situé en montagne ou en ville. Par exemple, la zone de montage 14 peut être intégrée au sein d'un bâtiment ouvert ou fermé. La zone de montage 14 peut comporter une fosse 17 comprenant un ou plusieurs étages. Par exemple, la zone de montage 14 comprend une fosse 17 comportant deux étages 18, 19 situés à des niveaux de hauteur différents. Dans le mode de réalisation illustré à la figure 1, un premier étage 18 est situé plus bas qu'un deuxième étage 19. Un tel mode de réalisation est particulièrement adapté à une station 1 d'embarquement d'un télésiège afin de pouvoir dégager les skis des personnes qui embarquent. Par ailleurs, les supports préfabriqués 10, 11 sont destinés à être posés sur l'endroit prédéterminé du sol formant la zone de montage 14. Les supports préfabriqués 10, 11 peuvent être posés directement sur l'endroit prédéterminé du sol. Par exemple, les supports préfabriqués 10, 11 peuvent être posés directement sur le fond de la fosse 17 qui forme alors la zone de montage 14. Selon un mode de réalisation, l'endroit prédéterminé du sol peut être recouvert en partie par un lit de sable 20, et les supports préfabriqués 10, 11 sont posés sur le lit de sable 20 qui forme la zone de montage 14. On peut aussi envisager de remplacer le lit de sable 20 par une chape réalisée en béton. On peut également réaliser plusieurs chapes en béton, chaque chape en béton étant destinée à recevoir un support préfabriqué 10, 11. Avantageusement, chaque chape en béton est ferraillée. En outre, on peut réaliser, sur la chape en béton, un mortier de scellement liquide formant la zone de montage 14, et on pose chaque support préfabriqué sur le mortier de scellement réalisé. Le mortier de scellement permet d'améliorer le contact physique du support préfabriqué 10, 11 avec la chape en béton. Selon encore un autre mode de réalisation, on peut réaliser une ou plusieurs butées en saillie de la chape en béton, et poser chaque support préfabriqué 10, 11 en appui sur lesdites butées formées. Les butées permettent de maintenir en position le support préfabriqué 10, 11 avec la chape en béton. Après avoir posé les supports préfabriqués 10, 11, on peut combler la fosse 17 avec un remblai, de terre ou de gravats, jusqu'au niveau 21, représenté ici en pointillés, du sol 22 avoisinant la zone de montage 14.In general, the prefabricated supports 10, 11 are placed at a predetermined location on the ground delimiting the mounting zone 14. The ground may be located in the mountains or in the city. For example, the mounting area 14 may be integrated within an open or closed building. The mounting zone 14 may comprise a pit 17 comprising one or more stages. For example, the mounting area 14 comprises a pit 17 having two stages 18, 19 located at different height levels. In the embodiment illustrated in figure 1 , a first stage 18 is located lower than a second stage 19. Such an embodiment is particularly suitable for a station 1 boarding a chairlift to be able to clear the skis of people who embark. Furthermore, the prefabricated supports 10, 11 are intended to be placed on the predetermined location of the ground forming the mounting zone 14. The prefabricated supports 10, 11 can be placed directly on the predetermined location of the ground. For example, the prefabricated supports 10, 11 can be placed directly on the bottom of the pit 17 which then forms the mounting zone 14. According to one embodiment, the predetermined location of the ground can be covered in part by a bed of sand 20, and the prefabricated supports 10, 11 are placed on the sand bed 20 which forms the mounting zone 14. It is also possible to consider replacing the sand bed 20 with a screed made of concrete. It is also possible to make several concrete screeds, each concrete screed being intended to receive a prefabricated support 10, 11. Advantageously, each concrete screed is scraped. In addition, it is possible, on the concrete screed, a liquid sealing mortar forming the mounting zone 14, and each prefabricated support is placed on the sealing mortar produced. The sealing mortar makes it possible to improve the physical contact of the prefabricated support 10, 11 with the concrete screed. According to yet another embodiment, it is possible to make one or more abutments projecting from the concrete screed, and to place each prefabricated support 10, 11 in abutment on said abutments formed. The stops allow to maintain in position the prefabricated support 10, 11 with the concrete screed. After placing the prefabricated supports 10, 11, the pit 17 can be filled with fill, earth or rubble, up to the level 21, shown here in dashed line, of the ground 22 next to the mounting zone 14.

Par ailleurs, la station 1 est démontable, c'est-à-dire que les différents éléments de la station 1 sont démontables et peuvent être transportés depuis la zone de montage 14 vers une autre zone distincte de la zone de montage 14, par exemple une zone de stockage non représentée sur la figure 1 à des fins de simplification. On entend ici par transport d'un élément de la station 1, un déplacement de l'élément d'une première zone vers une deuxième zone distincte et dans lequel on conserve l'intégrité de l'élément pour sa réutilisation dans la deuxième zone, par exemple pour un montage ultérieur d'une nouvelle station sur cette deuxième zone. En d'autres termes, la deuxième zone est située en dehors de la première zone. En particulier, les supports préfabriqués 10, 11 sont configurés pour être transportés depuis une première zone, par exemple depuis la zone de montage 14, vers une deuxième zone distincte de la première zone.Furthermore, the station 1 is removable, that is to say that the various elements of the station 1 are removable and can be transported from the mounting zone 14 to another zone separate from the mounting zone 14, for example a storage area not shown on the figure 1 for simplification purposes. Here is meant by transporting an element of the station 1, a displacement of the element of a first zone to a second distinct zone and in which the integrity of the element is preserved for its reuse in the second zone, for example for a subsequent editing of a new station on this second zone. In other words, the second zone is located outside the first zone. In particular, the prefabricated supports 10, 11 are configured to be transported from a first zone, for example from the mounting zone 14, to a second zone distinct from the first zone.

Les supports préfabriqués 10, 11 sont de préférence réalisés en béton dans une zone de fabrication 23 distincte de la zone de montage 14, c'est-à-dire que la zone de fabrication 23 est située en dehors de la zone de montage 14.The prefabricated supports 10, 11 are preferably made of concrete in a manufacturing zone 23 distinct from the mounting zone 14, that is to say that the manufacturing zone 23 is situated outside the mounting zone 14.

Par exemple, la zone de montage 14 peut être située à l'air libre ou non, en montagne ou en ville, et peut être plus ou moins éloignée de la zone de fabrication 23. La zone de fabrication 23 peut comporter un local 24 particulièrement adapté à la réalisation des pièces en béton. Par exemple, le local 24 est un local fermé dans lequel les pièces à réaliser ne sont pas soumises aux intempéries. Chaque support préfabriqué 10, 11 comprend une embase 25 surmontée d'un raidisseur 26 pour renforcer le support 10, 11 soumis notamment à la charge de la partie supérieure 2 de la station 1. Chaque support préfabriqué 10, 11 comporte en outre un socle 27, monté sur le raidisseur 26, destiné à recevoir un pylône 12, 13. Chaque support préfabriqué 10, 11 peut être réalisé en un seul bloc. En variante, un support préfabriqué 10, 11 peut comprendre plusieurs parties distinctes préfabriquées en béton. Par exemple, l'embase 25, le raidisseur 26 et le socle 27 peuvent former les parties distinctes d'un support préfabriqué 10, 11. Les parties distinctes d'un support 10, 11 sont réalisées séparément, et le support préfabriqué 10, 11 est réalisé par un assemblage des parties distinctes précitées. L'assemblage des parties du support préfabriqué 10, 11 peut être effectué dans la zone de fabrication 23, ou dans la zone de montage 14. Par ailleurs, on réalise les supports préfabriqués 10, 11 sur un marbre anti-adhérent posé dans le local 24 de manière à pouvoir lever le support préfabriqué 10, 11, après séchage, pour son transport. Le marbre peut être en bois ou en métal. On peut également enduire le marbre d'un produit anti-adhérant. Chaque support préfabriqué 10, 11 comporte également un système d'ancrage comprenant plusieurs tiges d'ancrage 28. Les tiges d'ancrage 28 sont en partie noyées au niveau du socle 27, dans le béton du support 10, 11, et permettent de fixer un pylône 12, 13 sur le socle 27. En outre, chaque support préfabriqué 10, 11 comporte un système de levage destiné au transport et à la pose du support préfabriqué 10, 11. Par exemple, le système de levage peut comprendre une seule ancre de levage 29 montée fixe sur le socle 27. En variante, le système de levage comporte un premier ensemble comprenant une ou plusieurs ancres de levages 29 destinées à supporter le poids du support préfabriqué 10, 11 lors de son transport, et un deuxième ensemble comprenant d'autres ancres de levages 29 montées sur le support de manière à l'équilibrer. Chaque support préfabriqué 10, 11 peut comporter trois ancres de levage 29 situées en triangle sur l'embase 25, ou quatre ancres de levage 29 situées aux quatre coins de l'embase 25, ou plusieurs ancres de levages 29 disposées sur le support de façon à répartir le poids, pour assurer à la fois l'équilibrage et le support du poids du support préfabriqué 10, 11. Les ancres de levage 29 sont également noyées en partie dans le béton du support 10, 11. Par exemple, chaque ancre de levage 29 comporte une tige 31 incorporée dans le béton du support 10, 11 et une tête 32, par exemple sphérique ou hémisphérique, qui est non noyée, c'est-à-dire qui est située à l'extérieur du support préfabriqué 10, 11. Les têtes 32 sont destinées à coopérer avec un anneau de levage relié à un crochet, par câble ou par chaîne, afin de lever le support préfabriqué 10, 11 pour le transporter d'une zone à l'autre. Un support préfabriqué 10, 11 peut avoir un poids environ égal à 60 tonnes. Selon un autre mode de réalisation, le système de levage comporte un ou plusieurs trous traversant formés dans une ou plusieurs parties du support préfabriqué 10, 11. Les trous traversant sont configurés pour le passage d'une barre métallique, ou d'un câble métallique, pour transporter le support préfabriqué 10, 11. Par ailleurs, chaque support préfabriqué 10, 11 peut comporter des moyens de fixation 30, et un câble de mise à la terre, non représenté ici à des fins de simplification. Le câble de mise à la terre est en partie noyé dans le béton du support 10, 11 de façon à relier une armature métallique entièrement noyée dans le béton du support 10, 11 à une carcasse métallique d'un pylône 12, 13 qui est, quant à elle, reliée à la terre.For example, the mounting zone 14 may be located in the open air or not, in the mountains or in the city, and may be more or less distant from the manufacturing zone 23. The manufacturing zone 23 may include a room 24 particularly suitable for producing concrete parts. For example, the room 24 is a closed room in which the parts to be made are not subjected to bad weather. Each prefabricated support 10, 11 comprises a base 25 surmounted by a stiffener 26 to reinforce the support 10, 11 subjected in particular to the load of the upper part 2 of the station 1. Each prefabricated support 10, 11 further comprises a base 27 , mounted on the stiffener 26, for receiving a pylon 12, 13. Each prefabricated support 10, 11 can be made in one block. Alternatively, a prefabricated support 10, 11 may comprise several separate prefabricated concrete parts. For example, the base 25, the stiffener 26 and the base 27 can form the distinct parts of a prefabricated support 10, 11. The separate parts of a support 10, 11 are made separately, and the prefabricated support 10, 11 is made by an assembly of the aforementioned distinct parts. The assembly of the parts of the prefabricated support 10, 11 can be carried out in the manufacturing zone 23, or in the mounting zone 14. Furthermore, the prefabricated supports 10, 11 are produced on a non-stick marble placed in the room 24 so as to lift the prefabricated support 10, 11, after drying, for its transport. The marble can be wood or metal. The marble can also be coated with a non-stick product. Each prefabricated support 10, 11 also comprises an anchoring system comprising several anchoring rods 28. The anchoring rods 28 are partly embedded at the base 27, in the concrete of the support 10, 11, and make it possible to fix a pylon 12, 13 on the base 27. In addition, each prefabricated support 10, 11 comprises a lifting system for transporting and installing the prefabricated support 10, 11. For example, the lifting system may comprise a single anchor In a variant, the lifting system comprises a first assembly comprising one or more lifting anchors 29 to support the weight of the prefabricated support 10, 11 during its transport, and a second set comprising other lifting anchors 29 mounted on the support so as to balance it. Each prefabricated support 10, 11 may comprise three lifting anchors 29 located in a triangle on the base 25, or four lifting anchors 29 situated at the four corners of the base 25, or a plurality of lifting anchors 29 arranged on the support of to distribute the weight, to ensure both the balancing and the weight support of the prefabricated support 10, 11. The lifting anchors 29 are also partially embedded in the concrete support 10, 11. For example, each anchor lifting 29 comprises a rod 31 incorporated in the concrete of the support 10, 11 and a head 32, for example spherical or hemispherical, which is not embedded, that is to say which is located outside the prefabricated support 10, 11. The heads 32 are intended to cooperate with a lifting ring connected to a hook, cable or chain, to lift the prefabricated support 10, 11 to transport it from one area to another. A prefabricated support 10, 11 may have a weight of about 60 tons. According to another embodiment, the lifting system comprises one or more through holes formed in one or more parts of the prefabricated support 10, 11. The through holes are configured for the passage of a metal bar, or a wire rope , to transport the prefabricated support 10, 11. Furthermore, each prefabricated support 10, 11 may comprise fixing means 30, and a grounding cable, not shown here for simplification purposes. The grounding cable is partially embedded in the concrete of the support 10, 11 so as to connect a metal reinforcement completely embedded in the concrete of the support 10, 11 to a metal carcass of a pylon 12, 13 which is, as for it, connected to the earth.

La station 1 peut en outre comporter un élément de liaison 33 fixé sur les deux supports préfabriqués 10, 11 afin, notamment, d'empêcher les supports préfabriqués 10, 11 de s'écarter l'un de l'autre. L'élément de liaison 33 comporte des moyens de fixation 34 destinés à coopérer avec les moyens de fixation 30 prévus sur les supports préfabriqués 10, 11. Par exemple, l'élément de liaison 33 peut comprendre une longrine 35 réalisée en béton. En outre, les moyens de fixation 30 prévus sur les supports préfabriqués 10, 11 peuvent être noyés dans le béton des supports 10, 11. Les moyens de fixation 30 comportent une partie d'ancrage 37 et un filetage interne mâle 38 pour recevoir un filetage externe femelle d'une première tige métallique 39, afin de visser la première tige 39 aux moyens de fixation 30. En outre, les moyens de fixation 34 de la longrine 35 peuvent comprendre des deuxième et troisième tiges métalliques 40, 41 noyées en partie dans le béton de la longrine 35 et au niveau des deux extrémités de la longrine 35. Afin de solidariser la longrine 35 avec le premier support préfabriqué 10, on rapproche la deuxième tige 40 de la première tige 39 vissée au premier support 10 et on coule un premier béton de liaison 42 entre le premier support préfabriqué 10 et la longrine 35 et autour des deux tiges rapprochées 39, 40. De la même manière, afin de solidariser la longrine 35 avec le deuxième support préfabriqué 11, on rapproche la troisième tige 41 de la première tige 39 vissée au deuxième support 11 et on coule un deuxième béton de liaison 43 entre le deuxième support préfabriqué 11 et la longrine 35 et autour des deux tiges rapprochées 39, 41. On réalise les bétons de liaison 42, 43 à l'aide d'un coffrage perdu destiné à être laissé autour des tiges rapprochées. On peut également effectuer le remblai de la fosse 17 sans attendre le séchage des bétons de liaison 42, 43 afin d'accélérer le montage de la station 1. De préférence, la longrine 35 est située sensiblement horizontalement par rapport à la charpente 5 de la station 1. Dans ce cas, selon la position des supports préfabriqués 10, 11 sur la zone de montage 14, les moyens de fixation 30 prévus sur les supports préfabriqués 10, 11 ne sont pas situés au même niveau. Par exemple, des moyens de fixation 30 peuvent être situés sur l'embase 25 du premier support préfabriqué 10, et des moyens de fixation 30 peuvent être situés sur le socle 27 du deuxième support préfabriqué 11.The station 1 may further comprise a connecting element 33 fixed on the two prefabricated supports 10, 11 in order, in particular, to prevent the prefabricated supports 10, 11 from moving away from each other. The connecting element 33 comprises fastening means 34 intended to cooperate with the means of fastening 30 provided on the prefabricated supports 10, 11. For example, the connecting element 33 may comprise a sill 35 made of concrete. In addition, the fixing means 30 provided on the prefabricated supports 10, 11 may be embedded in the concrete of the supports 10, 11. The fastening means 30 comprise an anchoring portion 37 and a male internal thread 38 for receiving a thread. external female of a first metal rod 39, in order to screw the first rod 39 to the fastening means 30. In addition, the fastening means 34 of the sill 35 may comprise second and third metal rods 40, 41 embedded partly in the concrete of the sill 35 and at the two ends of the sill 35. In order to secure the sill 35 with the first prefabricated support 10, the second shank 40 is brought closer to the first shank 39 screwed to the first support 10 and a first bonding concrete 42 between the first prefabricated support 10 and the sill 35 and around the two close rods 39, 40. Similarly, in order to secure the sill 35 with the second sup prefabricated port 11, it brings the third rod 41 of the first rod 39 screwed to the second support 11 and poured a second concrete connection 43 between the second prefabricated support 11 and the sill 35 and around the two rods 39, 41 close. realizes the bonding concretes 42, 43 using a lost formwork intended to be left around the close rods. The backfill of the pit 17 can also be carried out without waiting for the bonding concretes 42, 43 to dry in order to accelerate the mounting of the station 1. Preferably, the sill 35 is located substantially horizontally with respect to the frame 5 of the station 1. In this case, depending on the position of the prefabricated supports 10, 11 on the mounting area 14, the fixing means 30 provided on the prefabricated supports 10, 11 are not located at the same level. For example, fixing means 30 may be located on the base 25 of the first prefabricated support 10, and fixing means 30 may be located on the base 27 of the second prefabricated support 11.

Sur la figure 2, on a représenté de façon schématique les principales étapes d'un procédé de montage de la station 1 démontable décrite à la figure 1, et les principales étapes d'un procédé de démontage de cette station 1. De façon générale, le procédé de montage de la station 1 comporte une étape de préfabrication S1 dans laquelle on réalise chaque support préfabriqué 10, 11 en béton dans la zone de fabrication 23. Après l'étape de préfabrication, on effectue une étape de transport S2 de chaque support préfabriqué 10, 11, depuis la zone de fabrication 23, vers la zone de montage 14. Par exemple, on transporte les supports préfabriqués 10, 11 par camion, par hélicoptère, ou tout autre moyen motorisé suffisamment puissant pour soulever et transporter au moins un support préfabriqué 10, 11. Puis, après avoir transporté les supports préfabriqués vers la zone de montage 14, on effectue une étape de montage S3 de la station 1 comprenant une pose S33 de chaque support préfabriqué sur un endroit prédéterminé du sol délimitant la zone de montage 14. L'étape de montage S3 peut comprendre, avant la pose S33 des supports préfabriqués, une étape de terrassement S31 dans laquelle on creuse la fosse 17 dans le sol de la zone de montage 14. Après l'étape de terrassement S31, l'étape de montage S3 peut en outre comprendre un dépôt S32 du lit de sable 20, ou une réalisation d'une chape en béton, avec ou sans mortier de scellement, sur le fond de la fosse 17.On the figure 2 the main steps of a dismountable station 1 mounting method described in FIG. figure 1 , and the main steps of a dismantling process of this station 1. In general, the mounting method of the station 1 comprises a prefabrication step S1 in which each prefabricated support 10, 11 is made of concrete in the zone of 23. After the prefabrication step, a transport step S2 of each prefabricated support 10, 11 is carried out, from the manufacturing zone 23, to the mounting zone 14. For example, the prefabricated supports 10, 11 are transported. by truck, by helicopter, or any other motorized means powerful enough to lift and transport at least one prefabricated support 10, 11. Then, after having transported the prefabricated supports to the mounting zone 14, a mounting step S3 of the station 1 comprising an installation S33 of each prefabricated support on a predetermined location of the ground delimiting the mounting zone 14. The mounting step S3 may comprise, before the pos S33 of the prefabricated supports, an earth-moving step S31 in which the pit 17 is dug into the ground of the mounting zone 14. After the earth-moving step S31, the mounting step S3 may further comprise an S32 deposit of sand bed 20, or a realization of a concrete screed, with or without mortar, on the bottom of the pit 17.

Lors de l'étape de montage S3 de la station 1, on pose S33 chaque support préfabriqué 10, 11, soit directement sur le sol ou le fond de la fosse 17, soit sur le lit de sable 20 déposé au préalable sur le sol ou le fond de la fosse 17, soit sur la chape en béton. Par exemple, on pose le premier support préfabriqué 10 sur le fond du deuxième étage 19, par l'intermédiaire du lit de sable 20, et on pose le deuxième support préfabriqué 11 sur le fond du premier étage 18, par l'intermédiaire du lit de sable 20. Afin d'empêcher les supports préfabriqués 10, 11 de se déplacer l'un par rapport à l'autre, l'étape de montage S3 peut comprendre en outre une étape de fixation S34 de l'élément de liaison 33 entre les deux supports préfabriqués 10, 11. Puis, on monte chaque pylône 12 sur respectivement les premier et deuxième supports préfabriqués 10, 11. L'étape de montage S3 de la station 1 comporte en outre une étape d'assemblage S35 des éléments de la partie supérieure 2, dans laquelle on assemble la charpente 5, la poulie 6, le moteur 8, et l'arbre moteur 9. Préférentiellement, l'assemblage des éléments S35 est effectué en dehors de la zone de montage 14. Puis on monte la structure assemblée sur les pylônes 12, 13. Pour finaliser le montage de la station 1, on monte le toit 4 sur la charpente 5, puis le câble 7 sur la poulie 6.During the mounting step S3 of the station 1, S33 is placed each prefabricated support 10, 11, either directly on the ground or the bottom of the pit 17, or on the sand bed 20 previously deposited on the ground or the bottom of the pit 17, or on the concrete screed. For example, the first prefabricated support 10 is placed on the bottom of the second stage 19, via the sand bed 20, and the second prefabricated support 11 is placed on the bottom of the first stage 18, via the bed 20. In order to prevent the prefabricated supports 10, 11 from moving relative to each other, the mounting step S3 may further comprise a fixing step S34 of the connecting element 33 between the two prefabricated supports 10, 11. Then, we each pylon 12 is mounted on the first and second prefabricated supports 10, 11, respectively. The mounting step S3 of the station 1 also comprises an assembly step S35 of the elements of the upper part 2, in which the frame 5 is assembled. , the pulley 6, the motor 8, and the drive shaft 9. Preferably, the assembly of the elements S35 is carried out outside the mounting zone 14. Then the assembled structure is mounted on the pylons 12, 13. To finalize the mounting of the station 1, the roof 4 is mounted on the frame 5, then the cable 7 on the pulley 6.

Le procédé de démontage de la station 1, qui a été montée selon le procédé de montage décrit ci-avant, comprend une première étape D1 dans laquelle on démonte la partie supérieure 2 de la station 1. On démonte au préalable le câble 7 et le toit 4. Puis, on enlève la structure assemblée des pylônes 12, 13 et on la pose à côté de la zone de montage 14. Puis on démonte les différents éléments de la structure de façon à pouvoir les réutiliser, par exemple pour un montage ultérieur d'une nouvelle station, ou pour un autre usage. Le procédé peut également comprendre une étape de démontage D2 de la partie inférieure 3 de la station 1, dans laquelle on enlève les pylônes 12, 13 des supports préfabriqués 10, 11. Le procédé de démontage comporte en outre une troisième étape D3 dans laquelle on transporte chaque support préfabriqué 10, 11 depuis la zone de montage 14 vers une zone de stockage ou vers une nouvelle zone dans laquelle une nouvelle station peut être montée à partir des éléments démontés.The dismantling method of the station 1, which has been mounted according to the mounting method described above, comprises a first step D1 in which the upper part 2 of the station 1 is removed. The cable 7 and the cable are removed beforehand. roof 4. Then, the assembled structure of the towers 12, 13 is removed and placed next to the mounting zone 14. Then the various elements of the structure are dismounted so that they can be reused, for example for subsequent assembly. of a new station, or for another use. The method may also comprise a dismantling step D2 of the lower part 3 of the station 1, in which the towers 12, 13 are removed from the prefabricated supports 10, 11. The dismounting method also comprises a third step D3 in which one transports each prefabricated support 10, 11 from the mounting zone 14 to a storage zone or to a new zone in which a new station can be mounted from the disassembled elements.

Ainsi, on offre un procédé de montage d'une station de téléphérique robuste et qui dépend moins des conditions météorologiques. En outre, une telle station peut être entièrement démontable, permettant de replacer, sur un nouvel emplacement, une station qui ne peut plus être utilisée sur son site initial, par exemple en cas de risques d'avalanche qui n'auraient pas été prévus lors de la construction de la station.Thus, there is provided a method of mounting a cable car station robust and less dependent on weather conditions. In addition, such a station can be completely removable, to replace, in a new location, a station that can not be used on its original site, for example in case of avalanche risks that would not have been expected during the construction of the station.
