Description

Domaine de l'inventionField of the invention

L'invention concerne le domaine du confinement de procédés comportant des risques élevés d'émission de substances particulièrement toxiques ou radioactives.The invention relates to the field of the containment of processes involving high risks of emission of particularly toxic or radioactive substances.

Elle concerne plus généralement la sécurisation des infrastructures mettant en jeu des processus à haut risque lorsque sont présents des risques d'explosion (pyrotechnique, chimique, ...) et des risques d'émission de substances chimiques toxiques ou de substances radioactives.It more generally concerns the security of infrastructures involving high-risk processes when there are risks of explosion (pyrotechnic, chemical, etc.) and risks of emission of toxic chemical substances or radioactive substances.

Son objectif est d'assurer une protection collective en sécurité industrielle et civile.Its purpose is to provide collective protection in industrial and civil security.

Arrière plan technologiqueTechnological background

Lorsqu'un procédé met en présence des risques élevés d'explosion avec des risques élevés d'émission de substances particulièrement toxiques ou radioactives, il est souhaitable d'assurer un confinement du procédé dans une infrastructure telle qu'un bâtiment s'opposant à la dissémination de ces substances.When a process involves high risks of explosion with high risks of emission of particularly toxic or radioactive substances, it is desirable to ensure a confinement of the process in an infrastructure such as a building opposed to the dissemination of these substances.

En fonction de la quantité d'énergie mise en jeu en cas d'explosion, il peut être illusoire, ou tout du moins prohibitif, de réaliser un bâtiment totalement étanche à l'explosion.Depending on the amount of energy involved in an explosion, it may be illusory, or at least prohibitive, to make a building completely explosion-proof.

Dans le cas d'un bâtiment non étanche, il est possible de limiter la quantité d'effluents émis en définissant une surface de décharge qui va permettre de conserver l'intégrité du bâtiment, cette surface de décharge fonctionnant en soupape de décharge.In the case of an unsealed building, it is possible to limit the amount of effluent emitted by defining a discharge surface that will allow to maintain the integrity of the building, this discharge surface operating as a relief valve.

Dans le cadre de la présente invention on se place dans une configuration pour laquelle le bâtiment résiste à l'explosion et ne s'effondre pas.In the context of the present invention is placed in a configuration for which the building is resistant to the explosion and does not collapse.

Même si une partie des substances toxiques ou radioactives est émise au moment de l'explosion au travers de la surface de décharge du bâtiment, un reconfinement immédiat du bâtiment au niveau de la surface de décharge est très bénéfique et permet de fortement limiter, voire annuler, les émissions gazeuses ou particulaires après l'explosion et ainsi de limiter les risques d'effets délétères sur les personnels et les populations environnantes.Even if some of the toxic or radioactive substances are emitted at the time of the explosion through the discharge surface of the building, an immediate reconfinement of the building at the level of the discharge surface is very beneficial and can strongly limit or cancel , gaseous or particulate emissions after the explosion and thus limit the risk of deleterious effects on staff and surrounding populations.

Les solutions de confinement pour une protection collective dans le domaine des risques industriels sont à des stades de développement différents.Containment solutions for collective protection in the field of industrial risks are at different stages of development.

En cas d'incendie, le confinement par rideau d'eau déclenché sur détection incendie et cloisonnement coupe-feu sont aujourd'hui largement utilisés et de nombreux dispositifs réalisés selon ce principe sont disponibles.In case of fire, water curtain containment triggered on fire detection and fire partitioning are now widely used and many devices made according to this principle are available.

La réalisation de zones de confinement d'émissions gazeuses ou particulaires est bien connue pour les installations ne comportant pas de risque d'explosion.The realization of gaseous or particulate emission confinement zones is well known for non-explosive installations.

Pour des zones totalement déconfinées les technologies d'abattement par rideau d'eau sont largement employées.For totally unconfined areas, water curtain abatement technologies are widely used.

Les inconvénients du confinement par rideau d'eau sont son efficacité décroissante dans le temps et son autonomie limitée ou nécessitant une alimentation continue en eau.The disadvantages of water curtain containment are its decreasing efficiency over time and its limited autonomy or requiring a continuous supply of water.

Il existe aussi une technologie de reconfinement par porte mobile automatique ou commandée mais le problème principal est de garantir l'état fonctionnel de la porte après les effets de l'explosion et notamment l'onde de choc, les chocs de fragments ou la déformation du bâtiment.There is also a technology for automatic or controlled mobile door reconfinement, but the main problem is to guarantee the functional state of the door after the effects of the explosion and in particular the shock wave, the fragments shocks or the deformation of the door. building.

En outre ces portes ont un temps de mise en oeuvre non négligeable.In addition these doors have a time of implementation not negligible.

Un dispositif à rideau sec est en outre décrit dans la demande de brevet FR12 62332 A1 déposée le 19 décembre 2012 publiée le 20 juin 2014 sous le numéro FR 2 999 637 A1 . D'autres dispositifs sont connus des brevets US 3 687 185 A et GB 2 264 331 A .A dry curtain device is further described in the patent application FR12 62332 A1 filed on 19 December 2012 published on 20 June 2014 under the number FR 2 999 637 A1 . Other devices are known patents US 3,687,185 A and GB 2 264 331 A .

Brève description de l'inventionBrief description of the invention

La présente invention vise à fournir une solution de reconfinement à très court temps de réponse, à haute efficacité et étanchéité, à haute fiabilité et résistante aux agressions liées à l'explosion initiale : onde de choc, fragments, déformation du bâtiment.The present invention aims to provide a solution for reconfinement with a very short response time, with high efficiency and tightness, with high reliability and resistant to the aggressions related to the initial explosion: shock wave, fragments, deformation of the building.

Pour ce faire l'invention propose un dispositif de confinement à rideau déployable d'une première position enroulée ou pliée vers une seconde position déroulée, comportant un coffre de rangement du rideau dans la première position pour lequel le coffre est constitué d'une pluralité de modules juxtaposés, la pluralité de modules comprenant des modules actifs pourvus de moyens de retenue et de libération du rideau et des modules passifs dépourvus desdits moyens de retenue et de libération du rideau.To this end, the invention proposes a deployable curtain confinement device from a first wound or folded position to a second unrolled position, comprising a curtain storage box in the first position for which the box is made up of a plurality of juxtaposed modules, the plurality of modules comprising active modules provided with means for retaining and releasing the curtain and passive modules devoid of said means for retaining and releasing the curtain.

Avantageusement les moyens de retenue et de libération du rideau sont réalisés par des vérins.Advantageously, the means for retaining and releasing the curtain are made by jacks.

Plus particulièrement les vérins comportent un doigt, par exemple la tige du vérin, mobile entre une position déployée de retenue du rideau et une position rétractée de libération du rideau.More particularly, the cylinders comprise a finger, for example the rod of the jack, movable between an extended curtain retaining position and a retracted position of release of the curtain.

Description détaillée de modes de réalisation de l'inventionDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

La figure 1 décrit un dispositif réalisé selon l'invention et comportant un rideau sec 1 disposé de façon à pouvoir confiner ou reconfiner une zone de décharge, par exemple une ouverture 110 dans un mur 100, en réponse à une explosion. Le dispositif de l'invention est réalisé en sorte d'être de déploiement rapide et d'être peu susceptible d'être mis en défaut suite à une explosion.The figure 1 describes a device made according to the invention and comprising a dry curtain 1 arranged to be able to confine or reconfiner a discharge zone, for example an opening 110 in a wall 100, in response to an explosion. The device of the invention is designed to be of rapid deployment and to be unlikely to be faulted following an explosion.

Selon la figure 1, le rideau 1 est placé dans un coffre 2 lui-même placé sur la face externe d'un linteau de l'ouverture 110 à reconfiner.According to figure 1 , the curtain 1 is placed in a box 2 itself placed on the outer face of a lintel of the opening 110 to be reconfiner.

Le dispositif disposé à l'extérieur du bâtiment à reconfiner est ainsi protégé par le linteau des projections issues d'une explosion.The device disposed outside the building to be reconfiner is thus protected by the lintel projections from an explosion.

Le matériau du rideau est choisi en fonction des performances de résistance chimique nécessaires mais est typiquement constitué d'une trame tissée enduite sur les deux faces d'une ou plusieurs couches d'un ou plusieurs matériaux d'étanchéité, la trame étant en outre munie de raidisseurs horizontaux répartis sur toute la hauteur du rideau.The curtain material is chosen according to the required chemical resistance performance but typically consists of a woven fabric coated on both sides with one or more layers of one or more sealing materials, the weft being further provided with horizontal stiffeners distributed over the entire height of the curtain.

Le coffre de rangement du rideau est constitué d'une pluralité de modules juxtaposés 2a, 2b, 2c, 2d, la pluralité de modules comprenant des modules dits actifs 2b pourvus de moyens de retenue et de libération du rideau qui seront détaillés plus loin et des modules dits passifs 2a, 2c, 2d dépourvus desdits moyens de retenue et de libération du rideau 1.The storage chest of the curtain consists of a plurality of juxtaposed modules 2a, 2b, 2c, 2d, the plurality of modules comprising so-called active modules 2b provided with means for retaining and releasing the curtain which will be detailed later and so-called passive modules 2a, 2c, 2d devoid of said means for retaining and releasing the curtain 1.

En cas d'explosion, la réalisation du coffre en modules dimensionnés pour résister aux explosions permet une déformation du coffre en cas de déformation du linteau.In case of explosion, the realization of the box in modules sized to resist explosions allows a deformation of the box in case of deformation of the lintel.

Des clinquants d'étanchéité 201 sont disposés sur les interstices entre les modules et un solin d'étanchéité 202 est positionné sur le mur et recouvre les fixations 111, 11a des modules sur le mur.Sealing foils 201 are disposed on the interstices between the modules and a sealing flashing 202 is positioned on the wall and covers the fasteners 111, 11a of the modules on the wall.

Pour une porte de 4 m de largeur, et une hauteur de porte de 4 m, en considérant un débordement du rideau de 50 cm de chaque côté du dormant il faut un coffre sous forme d'un parallélépipède d'environ 0,8 x 0,6 x 5 m.For a door 4 m wide, and a door height of 4 m, considering a 50 cm curtain overhang on each side of the frame requires a chest in the form of a parallelepiped of about 0.8 x 0 , 6 x 5 m.

On choisit le nombre de modules adapté pour cette longueur sachant que l'on utilise deux modules d'extrémité 2a et deux modules actifs 2b, des modules passifs 2c de complément étant disposé autant que de besoin entre les modules actifs.The number of modules adapted for this length is chosen, knowing that two end modules 2a and two active modules 2b are used, passive modules 2c of complement being arranged as much as necessary between the active modules.

La durée de mise en place du rideau que l'on souhaite atteindre peut être estimée à moins d'une seconde puisque son déploiement correspond approximativement à une chute libre de 4 m de haut.The duration of installation of the curtain that one wishes to reach can be estimated at less than one second since its deployment corresponds approximately to a free fall of 4 m of height.

Il s'agit d'une chute libre et aucun guide n'est réalisé sur les côtés de l'ouverture, de tels guides ne pouvant que ralentir la chute du rideau voire le bloquer en cas de déformation suite à l'explosion.This is a free fall and no guide is made on the sides of the opening, such guides can only slow the fall of the curtain or block it in case of deformation following the explosion.

Un exemple de module actif est présenté en perspective à la figure 2 . An example of an active module is presented in perspective at the figure 2 .

Un tel module comporte comme les modules passifs une paroi supérieure 21, une paroi avant 22 et des parois latérales 23, les parois latérales 23 comportant des découpes arrondies de réception de tôles 24 de centrage du rideau.Such a module comprises, like the passive modules, an upper wall 21, a front wall 22 and side walls 23, the side walls 23 having rounded cut-outs for receiving sheets 24 for centering the curtain.

Il comporte en plus des modules passifs une trappe 21a d'accès aux moyens de retenue et de libération du rideau, un capot 22a sous lequel se positionne un moyen de retenue du rideau et un dispositif d'armement/désarmement des moyens de retenue et de libération du rideau.It comprises in addition to passive modules an access hatch 21a for access to the curtain retaining and release means, a cover 22a under which a curtain retaining means is positioned and a device for arming / disarming the retaining means and release of the curtain.

Toujours selon la figure 2, le rideau 1 est enroulé sur lui même et retenu par dans une enveloppe de stockage souple ou toile 7 réalisée dans le même matériau que le rideau, suspendue côté linteau à des barrettes de fixation 12, sur laquelle repose le rideau roulé et suspendue à l'opposée du linteau par des doigts 4 par exemple les tiges des vérins rétractables 3 des modules actifs 2b comme représenté en figure 3.Still according to the figure 2 , the curtain 1 is wound on itself and retained in a flexible storage envelope or canvas 7 made of the same material as the curtain, suspended on the lintel side to the fastening bars 12, on which the rolled curtain is suspended and suspended opposite the lintel by fingers 4 for example the rods of the retractable cylinders 3 of the active modules 2b as shown in FIG. figure 3 .

Selon l'exemple représenté en figure 3 , la toile 7 est assujettie à deux sangles de renfort 6 terminées chacune par une boucle métallique 6a pourvue de trous ou oeillets 5, 28.According to the example shown in figure 3 , the fabric 7 is subject to two reinforcing straps 6 each terminated by a metal loop 6a provided with holes or eyelets 5, 28.

En position de retenue du rideau, les doigts 4 des vérins 3 sont insérés dans les oeillets 5.In the curtain retaining position, the fingers 4 of the jacks 3 are inserted into the eyelets 5.

Les vérins et les boucles des sangles sont reçues dans les modules actifs comme représenté en figure 4 vue partielle en coupe d'un module actif qui comporte, sous la trappe 21a, une platine 25 sur laquelle est fixé le vérin 3 et une tôle avant 22b derrière le capot 22a pourvue d'un trou 4a de passage du doigt 4 du vérin 3.Cylinders and loops of the straps are received in the active modules as shown in figure 4 partial sectional view of an active module which comprises, under the hatch 21a, a plate 25 on which is fixed the cylinder 3 and a front plate 22b behind the cover 22a provided with a hole 4a for the passage of the finger 4 of the cylinder 3 .

La tôle avant 22b et le capot 22a sont éloignés de manière à réaliser un logement ou fente permettant introduire une boucle 6a d'une sangle 6 de retenue du rideau et réalisant un logement pour cette boucle.The front plate 22b and the cover 22a are spaced so as to provide a housing or slot for introducing a loop 6a of a strap 6 for retaining the curtain and providing a housing for this loop.

Pour permettre une mise en place aisée du rideau il est prévu de munir au moins un des modules actifs d'une poignée 26 de désarmement des moyens de libération du rideau.To allow easy placement of the curtain is provided to provide at least one of the active modules of a handle 26 disarming the curtain release means.

Cette poignée comporte un pêne 29 qui coulisse dans un tube 27 fixé perpendiculairement au capot 22a qui est percé pour laisser passer le pêne 29.This handle comprises a bolt 29 which slides in a tube 27 fixed perpendicular to the cover 22a which is pierced to let the bolt 29 pass.

Le pêne peut selon la position de la poignée coulisser ou non dans le tube 27 pour s'insérer dans l'oeillet 28 de la boucle 6 reçue dans le logement délimité par le capot 22a et la tôle 22b.Depending on the position of the handle, the bolt may or may not slide in the tube 27 to fit into the eyelet 28 of the loop 6 received in the housing delimited by the cover 22a and the plate 22b.

La figure 5 permet de voir la poignée d'armement et de désarmement dont l'axe du pêne est au dessus de l'axe du doigt 4 du vérin 3.The figure 5 allows to see the arming and disarming handle whose axis of the bolt is above the axis of the finger 4 of the cylinder 3.

Le fonctionnement du dispositif de désarmement est décrit aux figures 6A à 6D. Le désarmement désigne une position de blocage du rideau en position enroulée interdisant sa chute.The operation of the disarming device is described in Figures 6A to 6D . The disarmament designates a curtain locking position in the wound position preventing its fall.

Tout d'abord, le pêne 29 est adapté à s'engager, dans au moins une position de désarmement, dans les seconds oeillets 28 des sangles en sorte de retenir le rideau quelque-soit la position des doigts 4 des vérins 3.First, the bolt 29 is adapted to engage, in at least one disarming position, in the second eyelets 28 of the straps so as to retain the curtain whatever the position of the fingers 4 of the cylinders 3.

Un ressort de rappel 30 pousse la poignée dans le sens d'introduction du bout du pêne dans l'espace de réception de la boucle 6a.A return spring 30 pushes the handle in the direction of insertion of the end of the bolt into the receiving space of the loop 6a.

Le fonctionnement de la poignée est destiné à réaliser trois positions.The operation of the handle is intended to achieve three positions.

Une première position correspondant à la figure 6A permet de mettre le rideau en position de montage. Dans cette position le pan coupé 29a du pêne 29 peut s'effacer au passage de la boucle 6a jusqu'à ce que le pêne s'insère dans le trou ou oeillet 28 de la boucle ce qui permet de maintenir le rideau pendant le déploiement du doigt ou de la tige du vérin. Le pêne est ensuite rétracté.A first position corresponding to the Figure 6A allows to put the curtain in the mounting position. In this position the cutaway 29a of the bolt 29 can fade at the passage of the loop 6a until the bolt is inserted into the hole or eyelet 28 of the loop which allows to maintain the curtain during the deployment of the finger or rod of the cylinder. The bolt is then retracted.

Une deuxième position correspondant à la position de la figure 6B est une position de sécurité de blocage du système, position de désarmement. Dans cette position le pêne enfoncé dans le trou 28 de la boucle 6a ne peut s'effacer et le rideau est retenu quelque soit la positon des doigts.A second position corresponding to the position of the Figure 6B is a system lock safety position, disarm position. In this position the bolt pressed into the hole 28 of the loop 6a can not fade and the curtain is retained regardless of the position of the fingers.

Une troisième position correspondant à la position de la figure 6C est la position de fonctionnement du système, le pêne est rétracté ce qui fait que la retenue et la libération du rideau est dépendante de la position des doigts et dans le cas décrit, des tiges des vérins.A third position corresponding to the position of the Figure 6C is the operating position of the system, the bolt is retracted so that the retention and release of the curtain is dependent on the position of the fingers and in the case described, the rods of the cylinders.

Les trois positions sont permises par la réalisation dans le tube 27 recevant le pêne de trois rainures 271, 272, 273 de longueur croissante, la poignée étant tirée vers l'arrière contre le ressort 30 puis tournée pour passer de l'une à l'autre de ces positions.The three positions are allowed by the embodiment in the tube 27 receiving the bolt of three grooves 271, 272, 273 of increasing length, the handle being pulled back against the spring 30 and then turned to go from one to the other. other of these positions.

Les rainures 271, 272, 273 définissent ainsi en résumé trois positions de la poignée, une position de mise en place du rideau, une position de blocage du rideau et une position de libération du rideau.The grooves 271, 272, 273 thus define in summary three positions of the handle, a position of placing the curtain, a curtain locking position and a release position of the curtain.

La tige de préhension de la poignée est conçue et disposée en sorte de signaler à l'opérateur les positions du dispositif décrites ci-dessus et constitue pour ce faire un repère visuel.The gripping rod of the handle is designed and arranged so as to indicate to the operator the positions of the device described above and is for this purpose a visual cue.

La figure 7A représente les moyens de fixation d'un module sur le linteau de l'ouverture.The Figure 7A represents the means for fixing a module on the lintel of the opening.

Le module ici représenté est un module passif mais la fixation est la même pour les modules actifs.The module represented here is a passive module but the fixation is the same for the active modules.

Des tiges 10a, 10b filetées en bout sont fixées dans le mur soit scellées comme les tiges 10a soit traversantes et arrêtées par une tête 10' comme la tige 10b.End-threaded rods 10a, 10b are fixed in the wall either sealed as the rods 10a or through and stopped by a head 10 'like the rod 10b.

Les modules comportent une face arrière 8 pourvue de trous 9a, 9b permettant de recevoir les tiges 10a, 10b avec un jeu de positionnement permettant de bien positionner les modules 2 les uns à côté des autres.The modules comprise a rear face 8 provided with holes 9a, 9b for receiving the rods 10a, 10b with a positioning set to position the modules 2 closely together.

Des cales telles que des plots ou rondelles 11a percées d'un trou de réception des tiges sont positionnées pour appliquer la face arrière contre le linteau et des moyens de fixation tels des écrous 111 et rondelles 112 serrent les cales qui retiennent la face arrière des modules.Shims such as studs or washers 11a pierced with a hole for receiving the rods are positioned to apply the rear face against the lintel and fastening means such as nuts 111 and washers 112 clamp the shims which hold the rear face of the modules .

Selon la figure 7B , pour positionner les modules les uns par rapport aux autres, les modules comportent sur les bords latéraux de leur faces arrières 8, 8' un dispositif de positionnement mâle femelle qui selon l'exemple comporte d'un côté des pions 81 et de l'autre côté des découpes 82 de réception des pions.According to Figure 7B , to position the modules relative to each other, the modules comprise on the lateral edges of their rear faces 8, 8 'a female male positioning device which according to the example comprises on one side pins 81 and the other side of the blanks 82 for receiving the pins.

Une cale 11b, qui se trouve dans l'espace de réception du rideau, est avantageusement une cale massive arrondie éventuellement réalisé en matériau élastique comme un élastomère pour éviter de blesser ou coincer le rideau.A shim 11b, which is in the curtain receiving space, is advantageously a rounded massive shim possibly made of elastic material such as an elastomer to avoid injuring or trapping the curtain.

Pour fixer la toile 7, les barrettes de fixation 12 sont fixées sur la face arrière des modules par des moyens de fixation 13, 14 pourvus d'une plage de réglage de position dans la direction verticale de déploiement du rideau.To fix the fabric 7, the fastening strips 12 are fixed on the rear face of the modules by fastening means 13, 14 provided with a position adjustment range in the vertical direction of deployment of the curtain.

Ceci permet d'aligner les barrettes de fixation de tous les modules.This makes it possible to align the fixing bars of all the modules.

Les barrettes de fixation telles que représentées sont des barrettes comportant deux mors en L 12a, 12b pour pincer la toile 7.The fastening strips as shown are strips comprising two L-jaws 12a, 12b for gripping the fabric 7.

Les barrettes 12 ont une forme en L qui permet de plaquer le rideau contre le béton du linteau de façon à garantir l'étanchéité du rideau. La longueur de la partir horizontale du L est obtenu par empilement des cotes, par exemple en cohérence avec les épaisseurs des pièces 8 et 12a.The bars 12 have an L shape that allows to press the curtain against the concrete lintel to ensure the tightness of the curtain. The length of the horizontal part of the L is obtained by stacking the dimensions, for example in coherence with the thicknesses of the parts 8 and 12a.

Sur les côtés de la pièce 8 des dispositifs tels que des pointes/entailles de type male/femelles permettent d'aligner entre eux les modules 2.On the sides of the piece 8, devices such as male / female tips / notches make it possible to align the modules 2 with each other.

Les vérins rétractables sont par exemple activés par un signal électrique provenant d'une chaîne de détection d'explosion. Cette chaîne de détection d'explosion pourra être du type de celle décrite dans le brevet US 6 031 462 A .The retractable cylinders are for example activated by an electrical signal from an explosion detection chain. This explosion detection chain may be of the type described in FIG. US Patent 6,031,462 A .

On utilise de préférence des vérins électriques mais on peut aussi utiliser des actionneurs pyrotechniques ou des gâches électromagnétiques pour maintenir/relâcher le rideau.Electric actuators are preferably used but pyrotechnic actuators or electromagnetic strikes can also be used to hold / release the curtain.

Les modules sont dimensionnés mécaniquement pur résister à l'onde choc due à l'explosion et lors du montage, on recouvre les interstices entre les modules adjacents par des clinquants collés, de façon à améliorer l'étanchéité globale du coffre.The modules are dimensioned mechanically to withstand the shock wave due to the explosion and during assembly, we cover the interstices between the adjacent modules by glued foils, so as to improve the overall tightness of the trunk.

Les fixations sur le mur sont protégées par un capot de recouvrement dit solin.The fasteners on the wall are protected by a covering cover called flashing.

Le dispositif est conçu pour rester opérationnel après un temps de non utilisation très long sous des intempéries, naturelles ou pas.The device is designed to remain operational after a very long time of non-use under weather conditions, natural or not.

Le choix des vérins électrique est crucial de ce point de vue, ces derniers devant avoir une fiabilité excellente après une longue durée de stockage et par exemple il sera choisi d'utiliser des vérins pour trappes de désenfumage).The choice of electric cylinders is crucial from this point of view, the latter must have excellent reliability after a long storage period and for example it will be chosen to use cylinders for smoke evacuation traps).

Par ailleurs, le système de contrôle des vérins comporte un dispositif de synchronisation sur sa partie électrique, pour assurer que tous les modules actifs relâchent simultanément le rideau, de façon à éviter que ce dernier retombe de travers, et ne puisse atteindre le sol.In addition, the cylinder control system includes a synchronization device on its electrical part, to ensure that all the active modules simultaneously release the curtain, so as to prevent the latter from skewed, and can not reach the ground.
