Description

Système de pose et de dépose de gaines suspendues dans un bâtiment  System for laying and removing suspended ducts in a building
La présente invention concerne un système de pose et de dépose de gaines suspendues. Il est destiné à mettre en œuvre l'accrochage de gaines souples sous un plafond. The present invention relates to a system for installing and removing suspended ducts. It is intended to implement the attachment of flexible ducts under a ceiling.
II est connu de diffuser un air traité dans un bâtiment relativement volumineux, par exemple un bâtiment industriel, un magasin. On peut ainsi installer une gaine souple, par exemple une gaine textile sous le plafond, sous la toiture d'un bâtiment et la raccorder à une centrale de traitement d'air qui est conçue pour insuffler en fonctionnement de l'air traité, par exemple filtré, refroidi, réchauffé, au travers de ladite gaine. La paroi de la gaine de ventilation est perforée ou perméable de sorte que l'air admis sous légère surpression dans la gaine est diffusé dans l'enceinte du bâtiment.  It is known to distribute treated air in a relatively bulky building, for example an industrial building, a shop. It is thus possible to install a flexible sheath, for example a textile sheath under the ceiling, under the roof of a building and connect it to an air handling unit which is designed to inject treated air into operation, for example filtered, cooled, heated, through said sheath. The wall of the ventilation duct is perforated or permeable so that the air admitted under slight overpressure in the duct is distributed in the building.
Sur la Fig. 1 est présentée une manière conventionnelle de poser une gaine souple de ventilation G. Il faut tendre horizontalement un câble C entre deux murs opposés du bâtiment, une centrale de traitement d'air Ct étant fixée sur l'un des murs, sur l'une de ses faces ou encore au plafond. On tend le câble à l'aide de tendeurs T et l'on renforce la suspension du câble à l'aide de tirants R espacés à intervalles réguliers et qui sont suspendus sous le plafond ou sous la toiture. La gaine G est pourvue de multiples sangles terminées par des mousquetons M et qu'il convient d'accrocher sur le câble C. Pour réaliser cette suspension de la gaine, un opérateur utilise un engin de levage équipé d'une nacelle et dans laquelle il est soulevé à hauteur et à proximité de la centrale de traitement d'air Ct. Il raccorde l'extrémité ouverte de la gaine à une virole V portée par la centrale de traitement d'air. Il accroche ensuite tout ou partie des mousquetons M sur le câble C après avoir pris soin de fixer une ficelle sur le premier mousqueton. Il abaisse ensuite la nacelle et déplace l'engin porteur à proximité de chacun des tirants R, remonte dans la nacelle pour accrocher ou faire passer des mousquetons de l'autre côté dudit tirant, Il déplace à nouveau la nacelle pour l'approcher de l'autre mur et y remonte avec la ficelle qu'il tire pour déployer, tel un rideau de douche, la gaine dans sa longueur. L'autre extrémité de la gaine étant fermée, la gaine demeure tendue pendant le fonctionnement de la centrale de traitement d'air.  In FIG. 1 is presented a conventional way of laying a flexible ventilation duct G. It is necessary to extend a cable C horizontally between two opposite walls of the building, an air handling unit Ct being fixed on one of the walls, on one of its faces or the ceiling. The cable is stretched using tensioners T and the suspension of the cable is reinforced by means of tie rods R spaced at regular intervals and which are suspended under the ceiling or under the roof. The sheath G is provided with multiple straps terminated by carabiners M and which must be hung on the cable C. To make this suspension of the sheath, an operator uses a hoist equipped with a nacelle and in which he is raised at and near the air handling unit Ct. It connects the open end of the duct to a shell V carried by the air handling unit. He then hangs all or part of the carabiners M on the cable C after having taken care to fix a string on the first carabiner. He then lowers the basket and moves the carrier near each of the tie rods R, back in the basket to hang or pass karabiners on the other side of said tie rod, It moves the basket again to approach it. another wall and goes up with the string it pulls to deploy, like a shower curtain, the sheath in its length. With the other end of the sheath closed, the sheath remains tight during the operation of the air handling unit.
Dans le domaine agro-alimentaire, par exemple, la réglementation impose de nettoyer complètement au minimum une fois l'an, l'installation de production, y compris les gaines de ventilation qui doivent être démontées, nettoyées puis remontées. In the agri-food sector, for example, the regulations require that the production facility be completely cleaned up at least once a year. including the ventilation ducts which must be disassembled, cleaned and reassembled.
Dans une fromagerie en particulier, il faut vider complètement les hâloirs tous les quinze jours et aussi démonter, nettoyer et remonter les gaines.  In a cheese dairy in particular, you must empty the hives completely every two weeks and also dismantle, clean and reassemble the ducts.
Partant de ce constat, le demandeur a cherché une solution pour monter et démonter rapidement les gaines de ventilation habituellement utilisées dans les bâtiments industriels, les magasins, etc., tout en réduisant les risques d'accidents consécutifs à l'utilisation des engins de levage.  Based on this observation, the applicant has sought a solution to quickly assemble and disassemble the ventilation ducts usually used in industrial buildings, shops, etc., while reducing the risk of accidents resulting from the use of lifting gear. .

Le système 100 de pose et de dépose de gaines suspendues présenté sur la Fig. 2 est destiné à mettre en œuvre la pose et la dépose de gaines souples Gs sous le plafond d'un bâtiment.  The system 100 for laying and removing suspended ducts shown in FIG. 2 is intended to implement the installation and removal of flexible sleeves Gs under the ceiling of a building.
Une application intéressante consiste à l'utiliser pour poser, déposer des gaines souples destinées à la ventilation de l'enceinte du bâtiment.  An interesting application is to use it for laying, laying flexible ducts for ventilation of the building enclosure.
Une telle gaine souple Gs est constituée sur la Fig. 3, d'un tube cylindrique dont la paroi souple est fabriquée en tissu perméable à l'air ou est perforée d'orifices. Le tube est ouvert à l'une de ses extrémités et fermé de l'autre. Il peut être construit en un ou plusieurs tronçons suivant la longueur souhaitée de la gaine. Elle est destinée à être raccordée à une centrale de traitement d'air Cta qui est conçue pour insuffler en fonctionnement de l'air traité, par exemple filtré, refroidi, réchauffé, au travers de ladite gaine. La centrale Cta est par exemple fixée sous le plafond. Elle est pourvue d'une virole VI qui sert à raccorder la gaine.  Such a flexible sheath Gs is constituted in FIG. 3, a cylindrical tube whose flexible wall is made of breathable fabric or is perforated orifices. The tube is open at one end and closed at the other. It can be constructed in one or more sections depending on the desired length of the sheath. It is intended to be connected to a CTA air handling unit which is designed to inject into operation treated air, for example filtered, cooled, heated, through said sheath. The Cta plant is for example fixed under the ceiling. It is provided with a ferrule VI which serves to connect the sheath.
La paroi de la gaine de ventilation est perforée ou perméable de sorte que l'air admis sous légère surpression dans la gaine est diffusé dans l'enceinte du bâtiment. La géométrie cylindrique de la gaine est obtenue quand de l'air est insufflé dans celle-ci. Autrement elle demeure aplatie et elle peut ainsi être pliée pour faciliter son transport. The wall of the ventilation duct is perforated or permeable so that the air admitted under slight overpressure in the duct is distributed in the building. The cylindrical geometry of the sheath is obtained when air is blown into it. Otherwise it remains flat and can be folded to facilitate transport.
Des sangles Sg sont rapportées régulièrement sur la gaine souple Gs, par exemple par couture, pour la suspendre. Des connecteurs Cn conçus à cet effet sont respectivement fixés sur les extrémités libres des sangles Sg. Un tel connecteur Cn est présenté sur les Figs. 4, 5 et 6.  Straps Sg are regularly reported on the flexible sheath Gs, for example by sewing, to suspend it. Cn connectors designed for this purpose are respectively attached to the free ends of the straps Sg. Such a connector Cn is shown in Figs. 4, 5 and 6.
Sur la Fig. 2, le système 100 de pose et de dépose de gaines suspendues comprend un boîtier d'entraînement Bt d'un câble, un boîtier de renvoi Bv du câble qui sont réunis par l'intermédiaire d'un rail de guidage Rg.  In FIG. 2, the system 100 for laying and removing suspended ducts comprises a drive housing Bt of a cable, a gearbox Bv of the cable which are joined via a guide rail Rg.
Le système 100 est destiné à être fixé sous le plafond Pf d'un bâtiment.  The system 100 is intended to be fixed under the ceiling Pf of a building.
Sur la Fig. 9, le boîtier d'entraînement Bt comprend une plaque plane Ppl perforée de trous permettant sa fixation sous le plafond. Dans le même but, le boîtier de renvoi Bv comprend une plaque plane Pp2 perforée de trous permettant sa fixation sous le plafond.  In FIG. 9, the Bt drive housing comprises a flat plate Ppl perforated with holes for fixing under the ceiling. For the same purpose, the Bv gearbox comprises a flat plate Pp2 perforated with holes for fixing under the ceiling.
Sur la Fig. 10, le boîtier d'entraînement Bt est pourvu d'un mécanisme d'entraînement Mt d'un câble Cb de manière à le faire circuler en boucle, avec au moins l'un de ses deux brins entraîné dans le rail de guidage, en coopération avec le boîtier de renvoi, d'un moyen d'accrochage et de décrochage Me des connecteurs sur ledit câble.  In FIG. 10, the drive housing Bt is provided with a drive mechanism Mt of a cable Cb so as to circulate in a loop, with at least one of its two strands driven in the guide rail, in cooperation with the return housing, a means of attachment and unhook Me connectors on said cable.
Le mécanisme d'entraînement Mt comprend un entraîneur En, constitué sur cette Fig. 10, d'une manivelle, et qui est relié, par l'intermédiaire d'une transmission, à une première poulie PI autour de laquelle, le câble Cb est enroulé et qui peut être entraîné en boucle par l'entraîneur. La transmission comprend une chaîne reliant deux pignons respectivement montés sur l'axe de l'entraîneur En et sur l'axe de la poulie PI . Ces deux axes sont fixés perpendiculairement dans la plaque plane Ppl .  The drive mechanism Mt comprises a driver En, constituted in this FIG. 10, of a crank, and which is connected, via a transmission, to a first pulley PI around which, the cable Cb is wound and which can be driven in a loop by the trainer. The transmission comprises a chain connecting two pinions respectively mounted on the axis of the driver En and on the axis of the pulley PI. These two axes are fixed perpendicularly in the flat plate Ppl.
La poulie PI est disposée de telle sorte que sa gorge est positionnée dans le prolongement du moyen d'accrochage et de décrochage Me afin que l'un des deux brins du câble Cb et ici le brin Bl puissent être positionnés dans le moyen d'accrochage et de décrochage Me afin de circuler dans celui-ci.  The pulley PI is arranged so that its groove is positioned in the extension of the hooking and unhooking means Me so that one of the two strands of the cable Cb and here the strand B1 can be positioned in the hooking means and stall Me in order to flow in it.
Une poulie P2 de bifurcation est également fixée sur la plaque Ppl en étant positionnée de sorte à pouvoir renvoyer l'autre brin B2 à l'extérieur et le long du moyen d'accrochage et de décrochage Me pour circuler le long de celui-ci.  A bifurcation pulley P2 is also fixed on the plate Ppl being positioned so as to be able to return the other strand B2 outside and along the hooking and unhooking means Me to move along it.
Sur les Figs. 10 et 11, une extrémité du rail de guidage Rg est aboutée sur le moyen d'accrochage et de décrochage Me des connecteurs sur le câble Cb pour faire circuler à l'intérieur dudit du rail de guidage, le brin Bl du câble et faire circuler à l'extérieur et le long de celui-ci, le brin B2 dudit câble. Le moyen d'accrochage et de décrochage Me est fixé sur la plaque plane Ppl du boîtier d'entraînement Bt. Il est formé d'un conduit Cd creux longitudinalement et qui est traversé d'une fente Ft sur toute sa longueur, la fente Ft étant tournée du côté opposé de la plaque plane Ppl pour être tournée vers le bas dans la position de fonctionnement du boîtier d'entraînement Bt. Une extrémité du rail de guidage Rg est aboutée sur l'extrémité libre du conduit Cd. In Figs. 10 and 11, one end of the guide rail Rg abuts on the hooking means and unhook Me connectors on the cable Cb to make circulating within said guide rail, the strand Bl of the cable and circulate outside and along thereof, the strand B2 of said cable. The hooking and unhooking means Me is fixed on the flat plate Ppl of the drive housing Bt. It is formed of a hollow conduit Cd longitudinally and which is traversed by a slot Ft over its entire length, the slot Ft being turned on the opposite side of the flat plate Ppl to be turned down into the operating position of the drive housing Bt. One end of the guide rail Rg abuts on the free end of the conduit Cd.
Sur la Fig. 11, une fenêtre Fn traverse latéralement la paroi du conduit Cd. Cette fenêtre Fn est destinée à permettre l'accrochage et le décrochage des connecteurs sur le brin du câble qui est disposé dans le moyen d'accrochage et de décrochage Me.  In FIG. 11, a window Fn crosses laterally the wall of the duct Cd. This window Fn is intended to allow the hooking and unhitching of the connectors on the strand of the cable which is arranged in the hooking and unhooking means Me.
Sur la Fig. 7 est présenté un câble Cb. Il est formé de torons métalliques tressés. Le câble dispose, à intervalles réguliers, de douilles Dl en forme d'olive et qui sont destinées à caler en translation les connecteurs Cn, lorsqu'ils sont accrochés sur ledit câble.  In FIG. 7 is presented a cable Cb. It is formed of braided metal strands. The cable has, at regular intervals, D1 bushings in the form of olive and which are intended to wedge in translation connectors Cn, when they are hooked on said cable.
On remarquera que, en référence à la Fig. 11, la gorge de la poulie PI présente dans le mécanisme d'entraînement Mt du boîtier d'entraînement Bt est élargie localement formant des logements Lg de dimensions adaptées pour pouvoir réceptionner lesdites douilles.  It will be appreciated that with reference to FIG. 11, the groove of the pulley PI present in the drive mechanism Mt of the drive housing Bt is widened locally forming housings Lg of suitable dimensions to be able to receive said bushings.
Sur les Figs. 5 et 6, est présenté un connecteur Cn destiné à être accroché sur le câble pour, en coopération avec d'autres, suspendre la gaine dans le système de pose et de dépose de gaines de l'invention.  In Figs. 5 and 6, there is shown a connector Cn intended to be hooked on the cable for, in cooperation with others, suspend the sheath in the laying system and removal of ducts of the invention.
Le connecteur Cn est constitué d'une plaque Pq traversée d'un passage Pg et dans laquelle il convient d'enfiler et d'attacher une sangle de suspension de la gaine qui est surmontée d'un moyen de fixation Mf destiné à suspendre ledit connecteur sur le câble et le caler latéralement sur une douille Dl correspondante.  The connector Cn consists of a plate Pq traversed by a passage Pg and in which it is necessary to thread and attach a suspension strap of the sheath which is surmounted by a fixing means Mf for suspending said connector on the cable and wedge it laterally on a corresponding Dl socket.
Ce moyen de fixation Mf comprend, un moyen d'accrochage destiné à suspendre ledit connecteur sur le câble ainsi qu'un moyen de calage destiné à caler latéralement ledit connecteur sur une douille correspondante.  This fastening means Mf comprises a hooking means for suspending said connector on the cable and a wedging means for wedging said connector laterally on a corresponding socket.
De manière plus précise, le moyen de fixation Mf est avantageusement constitué de deux crochets latéraux Cil et C12. Ces deux crochets sont respectivement formés sur cette Fig. 5, de deux portions Pcl, Pc2, de cylindres coaxiaux qui surmontent les deux côtés latéraux de la plaque Pq délimitant une géométrie en U au connecteur lorsqu'il est présenté en vue de face comme cela apparaît sur la Fig. 5. Le diamètre des portions Pc cylindriques est nettement plus grand que l'épaisseur de la plaque Pq. La plaque Pq se raccorde dans le plan médian des deux portions cylindriques Pc. Le connecteur Cn présente ainsi une géométrie symétrique dans un plan médian de l'épaisseur de sa plaque Pq, ce qui simplifie son montage sur la sangle. More specifically, the fixing means Mf is advantageously constituted by two lateral hooks C11 and C12. These two hooks are respectively formed in this FIG. 5, of two portions Pcl, Pc2, of coaxial cylinders which surmount the two lateral sides of the plate Pq delimiting a U-shaped geometry to the connector when it is presented in front view as it appears in FIG. 5. The diameter of the cylindrical portions Pc is significantly larger than the thickness of the plate Pq. The plate Pq is connected in the median plane of the two cylindrical portions Pc. The connector Cn thus has a symmetrical geometry in a median plane of the thickness of its plate Pq, which simplifies its mounting on the strap.
Les deux portions cylindriques Pc sont traversées coaxialement de deux trous The two cylindrical portions Pc are coaxially traversed by two holes
Tl, T2 pour réceptionner le câble. Chaque trou T est prolongé radialement et dans une direction oblique descendante, dans la position de pose du connecteur Cn, d'une rainure Rn qui débouche au travers de la portion cylindrique correspondante Pc. T1, T2 to receive the cable. Each hole T is extended radially and in an oblique downward direction, in the laying position of the connector Cn, a groove Rn which opens through the corresponding cylindrical portion Pc.
Le connecteur Cb s'accroche facilement sur le câble et il demeure accroché par l'effet de la gravité sur le câble.  The Cb connector is easily attached to the cable and remains hooked by the effect of gravity on the cable.
La distance séparant les deux crochets latéraux Cil et C12 est plus grande que la longueur d'une douille Dl. La douille peut alors prendre place entre les deux crochets latéraux Cil et C12.  The distance separating the two lateral hooks C11 and C12 is greater than the length of a sleeve D1. The socket can then take place between the two lateral hooks Cil and C12.
On peut ainsi, en référence aux Figs. 4, 5 et 6, accrocher le connecteur Cn en engageant obliquement vers le bas ses deux rainures Rn sur le câble Cb pour que ledit connecteur Cn puisse être retenu sur ledit câble, celui-ci prenant place dans les deux trous Tl et Tl.  Thus, with reference to FIGS. 4, 5 and 6, hook the connector Cn by engaging obliquely downwards its two grooves Rn on the cable Cb so that said connector Cn can be retained on said cable, the latter taking place in the two holes T1 and T1.
Le connecteur Cn est accroché préférentiellement sur le câble Cb en chevauchant une douille Dl, c'est-à-dire qu'il est accroché avec ses deux crochets latéraux Cil et C12 disposés de chaque côté des deux extrémités de la douille Dl, pour caler en translation le connecteur Cn sur le câble Cb.  The connector Cn is preferably hooked on the cable Cb by overlapping a sleeve D1, that is to say it is hooked with its two lateral hooks C11 and C12 disposed on each side of the two ends of the sleeve D1, to wedge in translation the connector Cn on the cable Cb.
Le boîtier de renvoi Bv présenté sur les Figs. 12 et 13 est destiné à retenir l'autre boucle d'enroulement du câble Cb. Il comprend une poulie P3 autour de laquelle peut circuler en boucle ledit câble, un tiroir Tr dans lequel est monté l'axe de la poulie P3, lequel tiroir étant monté à coulissement, par l'intermédiaire d'au moins un arbre de guidage Ag et deux arbres Agi, Ag2 sur la Fig. 12, dans un tendeur Td comprenant un support Sp fixé sur la plaque plane Pp2. Le tendeur Td comprend un tirant Tt fixé sur le tiroir Tr et qui est monté à coulissement dans le support Sp à l'encontre d'un moyen de rappel Rp, tel qu'un ressort. Le câble demeure correctement tendu.  The Bv gearbox shown in Figs. 12 and 13 is intended to hold the other winding loop of the cable Cb. It comprises a pulley P3 around which can circulate in loop said cable, a drawer Tr in which is mounted the axis of the pulley P3, which slide is slidably mounted, via at least one guide shaft Ag and two shafts Ag1, Ag2 in FIG. 12, in a tensioner Td comprising a support Sp fixed on the flat plate Pp2. The tensioner Td comprises a tie rod Tt fixed on the drawer Tr and which is slidably mounted in the support Sp against a return means Rp, such as a spring. The cable remains properly tensioned.
La poulie P3 est disposée de telle sorte que sa gorge est positionnée dans le prolongement du rail de guidage Rg afin que l'un des deux brins du câble Cb et ici le brin B 1 puissent être positionnés dans le rail de guidage Rg afin de circuler dans celui- ci et que l'autre brin B2 puisse circuler le long dudit rail de guidage. Le rail de guidage Rg peut être fixé sur la plaque plane Pp2 à l'aide de deux pattes de fixation Pnl et Pn2. The pulley P3 is arranged in such a way that its groove is positioned in the extension of the guide rail Rg so that one of the two strands of the cable Cb and here the strand B1 can be positioned in the guide rail Rg in order to circulate. in this and that the other strand B2 can flow along said guide rail. The guide rail Rg can be fixed on the flat plate Pp2 by means of two fixing lugs Pn1 and Pn2.
Des capotages, non représentés, recouvrent en principe les mécanismes présents sur les plaques planes du boîtier d'entraînement et du boîtier de renvoi.  Cowlings, not shown, in principle cover the mechanisms present on the flat plates of the drive housing and the return housing.
Sur les Figs. 14 et 15, le rail de guidage Rg est constitué d'un profilé de section constante comprenant une embase de fixation Ef sur le plafond et sous laquelle s'étend un conduit Co traversé sur toute sa longueur d'une fente longitudinale Ftl, laquelle est tournée du côté opposé à l'embase de fixation Ef pour être tournée vers le bas dans la position de pose dudit rail de guidage. La fente Ftl est définie entre deux parois obliques Pol, Po2 et dont les bords libres sont tournés vers le bas. Les deux parois obliques forment entre elles un angle de pratiquement 90 °. Deux saignées Sn longitudinales creusent la face inférieure de l'embase de fixation Ef des deux côtés du conduit Co, pour faciliter le positionnement de vis de fixation du connecteur sur le plafond.  In Figs. 14 and 15, the guide rail Rg consists of a section of constant section comprising a fixing base Ef on the ceiling and under which extends a conduit Co traversed over its entire length of a longitudinal slot Ftl, which is turned on the opposite side to the fixing base Ef to be turned down in the laying position of said guide rail. The slot Ft1 is defined between two oblique walls Pol, Po2 and whose free edges are facing downwards. The two oblique walls form an angle of almost 90 ° between them. Two longitudinal snakes Sn excavate the underside of the mounting base Ef on both sides of the duct Co, to facilitate the positioning of connector fixing screws on the ceiling.
Sur la Fig. 16, les portions cylindriques Pc du connecteur Cn sont retenues dans le conduit Co, en prenant appui latéralement sur les deux parois obliques Po alors que sa plaque médiane Pq ressort au travers de la fente longitudinale Ftl . On remarque la présence d'ergots Eg disposés de part et d'autre de la plaque Pq, également visible sur la Fig. 5. Ils sont destinés à éviter le coincement par arcboutement du connecteur Cn dans le rail de guidage Rg pendant son coulissement dans celui-ci.  In FIG. 16, the cylindrical portions Pc of the connector Cn are retained in the conduit Co, bearing laterally on the two oblique walls Po while its central plate Pq exits through the longitudinal slot Ftl. Note the presence of pins Eg disposed on either side of the plate Pq, also visible in FIG. 5. They are intended to avoid the jamming of the connector Cn in the guide rail Rg during its sliding in it.
Ainsi, et en référence à la Fig. 9, en tournant la manivelle En, on déplace dans un sens le brin Bl du câble Cb dans le rail de guidage Rg alors que l'autre brin B2 circule dans l'autre sens le long du rail de guidage Rg.  Thus, and with reference to FIG. 9, turning the crank En, the strand B1 of the cable Cb is moved in one direction in the guide rail Rg while the other strand B2 flows in the other direction along the guide rail Rg.
Sur la Fig. 17, est présenté un raccord de jonction Rj destiné à réunir deux tronçons consécutifs d'un rail de guidage Rg. Il se compose d'un profilé comprenant une embase de fixation Ef2 sur le plafond et sous laquelle s'étend un conduit Co2 et qui se prolonge de part et d'autre de l'embase de fixation Ef2 en considérant l'axe longitudinal dudit raccord de jonction. Le conduit Co2 est traversé sur toute sa longueur d'une fente longitudinale Ft2, laquelle est tournée du côté opposé de l'embase de fixation Ef2 pour être tournée vers le bas dans la position de pose dudit rail de guidage. La section interne du conduit Co2 est un peu plus grande que celle externe du conduit Co d'un tronçon du rail de guidage Rg permettant ainsi de réceptionner deux extrémités de deux tronçons à assembler dans le prolongement l'un de l'autre, pour garantir une continuité de circulation des connecteurs dans toute la longueur du rail de guidage Rg. La flèche F symbolise le montage d'une extrémité d'un tronçon du rail de guidage Rg dans le raccord de jonction Rj. Son embase de fixation Ef2 est fixée par vissage sur le plafond. Le raccord de jonction Rj peut être pourvu latéralement à son conduit Co2 d'un support de guidage, non représenté, du brin du câble circulant à l'extérieur du rail de guidage. In FIG. 17, is presented a junction connection Rj for joining two consecutive sections of a guide rail Rg. It consists of a profile comprising a mounting base Ef2 on the ceiling and under which extends a conduit Co2 and which extends on either side of the mounting base Ef2 by considering the longitudinal axis of said coupling junction. The conduit Co2 is traversed along its length by a longitudinal slot Ft2, which is turned on the opposite side of the fixing base Ef2 to be turned downwards in the laying position of said guide rail. The internal section of the duct Co2 is slightly larger than the external one of the duct Co of a section of the guide rail Rg thus making it possible to receive two ends of two sections to be assembled in the extension of one another, in order to guarantee continuity of circulation of the connectors throughout the length of the guide rail Rg. The arrow F symbolizes the mounting of one end of a section of the guide rail Rg in the junction connection Rj. Its mounting base Ef2 is fixed by screwing on the ceiling. The junction connection Rj may be provided laterally with its conduit Co2 a guide support, not shown, the strand of the cable flowing outside the guide rail.
Sur la Fig. 18, on distingue l'emboîtement de l'extrémité d'un tronçon du rail de guidage Rg dans le conduit Co2 du raccord de jonction Rj.  In FIG. 18, there is the interlocking of the end of a section of the guide rail Rg in the conduit Co2 of the junction connection Rj.
La pose et le fonctionnement du système 100 de pose et de dépose de gaines suspendues de l'invention se présentent de la manière suivante.  The installation and operation of the system 100 for laying and removing suspended ducts of the invention are as follows.
Concernant la pose, il convient de fixer contre le plafond Pf d'un bâtiment, le boîtier d'entraînement Bt ainsi que le boîtier de renvoi Bv. Le boîtier d'entraînement Bt est fixé au plafond Pf dans le prolongement de la virole VI de la centrale de traitement d'air Cta, comme cela apparaît sur la Fig. 8.  As for the installation, it is advisable to fix against the ceiling Pf of a building, the drive box Bt as well as the return box Bv. The drive housing Bt is fixed to the ceiling Pf in the extension of the shell VI of the air handling unit Cta, as shown in FIG. 8.
On réunit le boîtier d'entraînement Bt et le boîtier de renvoi Bv par l'intermédiaire du rail de guidage Rg et qu'il convient également de fixer contre le plafond. On peut utiliser des raccords de jonction Rj pour réunir, le cas échéant, les différents tronçons constitutifs du rail de guidage Rg.  The drive unit Bt and the gearbox Bv are connected via the guide rail Rg and must also be fixed against the ceiling. Junction connectors Rj may be used to join, where appropriate, the different constituent portions of the guide rail Rg.
On peut utiliser un engin de levage équipé d'une nacelle soulevée en direction du plafond et dans laquelle intervient un opérateur pour réaliser ce travail. Ce travail n'est réalisé qu'une seule fois.  A hoist can be used equipped with a platform lifted towards the ceiling and in which an operator intervenes to perform this work. This work is done only once.
La pose d'une gaine souple de ventilation Gs se présente de la manière suivante. Il convient d'utiliser là encore un engin de levage équipé d'une nacelle. La nacelle est soulevée avec l'opérateur ainsi que la gaine souple Gs, sous le boîtier d'entraînement Bt et à une distance du plafond telle que l'opérateur puisse se tenir debout dans ladite nacelle. L'opérateur prend le premier connecteur Cn situé au plus près de l'extrémité fermée de la gaine souple Gs et le présente devant la fenêtre Fn. Il tourne la manivelle En de sorte à déplacer le brin B 1 du câble Cb visible au travers de ladite fenêtre jusqu'à ce qu'une douille Dl que le câble porte, se présente devant la fenêtre Fn. L'opérateur accroche le connecteur Cn en enfourchant ladite douille si bien que le connecteur Cn est accroché sur le câble Cb et sans faculté de glisser le long de celui-ci le câble Cb. L'opérateur tourne à nouveau la manivelle En et la plaque Pq du connecteur Cn coulisse dans la fente Ftl du conduit Cd du rail de guidage Rg et les deux portions de cylindre Pcl et Pc2 du connecteur Cn coulissent dans ledit conduit si bien que le connecteur ne possède plus qu'un seul degré de liberté et ne peut être décroché du câble. The installation of a flexible ventilation duct Gs is as follows. It is appropriate to use again a hoist equipped with a nacelle. The nacelle is raised with the operator and the flexible sheath Gs, under the Bt drive housing and at a distance from the ceiling such that the operator can stand in said nacelle. The operator takes the first connector Cn located closer to the closed end of the flexible sheath Gs and presents it in front of the window Fn. It turns the crank En so as to move the strand B 1 of the cable Cb visible through said window until a bushing Dl that the cable carries, is in front of the window Fn. The operator hooks the connector Cn by burying said socket so that the connector Cn is hooked on the cable Cb and without the ability to slide along the cable Cb. The operator rotates the crank En and the plate Pq of the connector Cn slides in the slot Ftl of the conduit Cd of the guide rail Rg and the two cylinder portions Pcl and Pc2 of the connector Cn slide in said conduit if although the connector has only one degree of freedom and can not be removed from the cable.
L'opérateur continue de tourner la manivelle En pour entraîner le connecteur Cn qui porte la gaine souple Gs dans le rail de guidage Rg et jusqu'à ce qu'un second connecteur Cn se présente devant la fenêtre Fn. Il accroche un second connecteur, puis le fait avancer dans le rail de guidage Rg en tournant la manivelle En. Il procède de la même manière pour l'ensemble des connecteurs Cn qui sont alors retenus dans le rail de guidage, en portant la gaine souple Gs, de sorte qu'elle demeure suspendue sous le rail de guidage en étant étirée. Lorsque le dernier connecteur a été envoyé dans le rail de guidage, il ne reste à l'opérateur qu'à fixer l'extrémité ouverte de la gaine souple Gs dans la virole VI de la centrale de traitement d'air Cta. La nacelle est abaissée. La centrale de traitement d'air Cta est mise en fonctionnement et de l'air traité est insufflé dans la gaine souple Gs qui le diffuse dans le bâtiment.  The operator continues to turn the crank In to drive the connector Cn which carries the flexible sheath Gs in the guide rail Rg and until a second connector Cn is in front of the window Fn. It hooks a second connector, then advances it in the guide rail Rg by turning the handle In. It proceeds in the same manner for all the connectors Cn which are then retained in the guide rail, carrying the flexible sheath Gs, so that it remains suspended under the guide rail being stretched. When the last connector has been sent into the guide rail, it is only up to the operator to fix the open end of the flexible sheath Gs in the shell VI of the air handling unit Cta. The nacelle is lowered. The Cta air handling unit is put into operation and treated air is blown into the flexible duct Gs which diffuses it into the building.
Le démontage de la gaine souple Gs se présente de la manière suivante. L'opérateur utilise un engin de levage équipé d'une nacelle et qui est élevé sous le boîtier d'entraînement Bt. L'opérateur démonte l'extrémité de la gaine Gs, de la virole VI de la centrale de traitement d'air Cta. Il entraîne ensuite la manivelle En dans l'autre sens. Le dernier connecteur Cn apparaît au travers de la fenêtre Fn, puis est ensuite éjecté vers l'extérieur de la fenêtre Fn en venant sur une butée Bu, visible sur la Fig. 11 et qui est formée par une paroi latérale de la fenêtre et qui est disposée à proximité du premier brin Bl du câble Cb. Tous les connecteurs Cn sont éjectés successivement de la sorte pendant la manœuvre de la manivelle En. Préférentiellement la paroi latérale formant butée Bu est biseautée en étant ouverte vers l'extérieur pour favoriser l'éjection des connecteurs Cn. La gaine peut alors être démontée rapidement, par exemple pour procéder à un nettoyage ou à son remplacement.  Disassembly of the flexible sheath Gs is as follows. The operator uses a lifting gear equipped with a nacelle and which is raised under the drive box Bt. The operator dismounts the end of the sheath Gs, of the ferrule VI of the air handling unit Cta . He then drives the hand crank In the other direction. The last connector Cn appears through the window Fn, and is then ejected outside the window Fn coming on a stop Bu, visible in FIG. 11 and which is formed by a side wall of the window and which is disposed near the first strand B1 of the cable Cb. All connectors Cn are ejected successively in this way during the operation of the crank In. Preferably, the lateral wall forming the abutment Bu is bevelled by being open towards the outside to favor the ejection of the connectors Cn. The sheath can then be disassembled rapidly, for example to carry out a cleaning or its replacement.
Dans une variante de réalisation, non représentée, seule la butée subsiste dans le moyen d'accrochage et de décrochage, la fenêtre étant aussi absente. La butée peut avantageusement être disposée à proximité de la gorge de la poulie du mécanisme d'entraînement. L'action de la gorge de la poulie sur les portions cylindriques du connecteur ainsi que l'action de la butée sur un bord latéral du connecteur réalisent l'éjection du connecteur du câble.  In an alternative embodiment, not shown, only the stop remains in the hooking and unhooking means, the window being also absent. The stop may advantageously be disposed near the groove of the pulley of the drive mechanism. The action of the groove of the pulley on the cylindrical portions of the connector and the action of the stop on a side edge of the connector perform the ejection of the cable connector.
Le système 100 de pose et de dépose de gaines suspendues de l'invention permet de poser et de déposer simplement et rapidement une gaine souple sous le plafond d'un bâtiment. L'engin de levage utilisé pour monter ou démonter la gaine souple demeure en poste fixe et minimise les risques d'accidents. The system 100 for installing and removing suspended ducts of the invention makes it possible to simply and quickly install and deposit a flexible sheath under the ceiling of a building. The lifting gear used to assemble or dismount the flexible sheath remains in a fixed position and minimizes the risk of accidents.
Dans une autre variante de réalisation, non représentée, l'entraîneur comprend un moteur électrique à sens de rotation réversible. Sa commande est préférentiellement mise en œuvre à l'aide d'une télécommande. L'opérateur peut ainsi dégrafer tous les connecteurs depuis le sol, en utilisant la télécommande.  In another variant embodiment, not shown, the trainer comprises an electric motor with a reversible direction of rotation. Its control is preferably implemented using a remote control. The operator can thus unclip all connectors from the ground, using the remote control.
