The curtain has two walls (11) which are joined together along their lower edges (11d) and vertical sides. The sprinklers are positioned so that they spray liquid onto the inner surface of at least one of the walls. At least one of the curtain's vertical edges has outlets for the liquid adjacent to its lower edge, linked to a recuperator. Additionally, the inside of the curtain has spacers (13) between the walls. The spacers are able to slide along a central strip or cable (15) and break under the weight of one wall of the curtain.

Description

La présente invention concerne un rideau coupe-feu.The present invention relates to a fire curtain.

De tels rideaux sont utilisés dans les constructions, et notamment dans les établissements recevant du public, afin d'éviter la propagation des incendies entre différentes parties de la construction. Ces rideaux permettent ainsi de compartimenter de grands volumes et sont généralement constitués d'une toile limitant la propagation des flammes et des fumées lors d'un incendie.Such curtains are used in constructions, and especially in establishments receiving from the public, in order to avoid the spread of fires between different parts of the building. These curtains thus make it possible to compartmentalize large volumes and usually consist of a canvas limiting the spread of flames and fumes during of a fire.

Ces rideaux sont en général repliés en temps normal et ne sont déployés qu'en cas d'incendie.These curtains are usually folded in time normal and are only deployed in the event of a fire.

Il est connu d'arroser ces rideaux uniformément sur l'une des faces de la toile, afin notamment de limiter la propagation de la chaleur et la montée en température de la toile.It is known to water these curtains evenly on one side of the canvas, in particular to limit the spread of heat and the rise in canvas temperature.

Cependant, ces rideaux nécessitent de créer au niveau du sol des rigoles pour récupérer l'eau à l'extrémité inférieure du rideau. Ces rigoles de récupération forment des obstacles et ne peuvent pas être masquées par un revêtement de sol.However, these curtains require creating at channel level to collect water from the lower end of the curtain. These channels of recovery form obstacles and cannot be masked by a floor covering.

De plus, une récupération correcte de l'eau n'est réalisée que si le rideau est dans sa position normale verticale. Or, il n'est pas rare que le rideau, sous l'effet du vent ou à cause d'obstacles, soit dévié de cette position verticale lorsqu'il est déployé en cas d'incendie. L'eau est mal, voire pas du tout, récupérée dans les rigoles, provoquant ainsi l'inondation des locaux. In addition, correct water recovery is only carried out if the curtain is in its position normal vertical. However, it is not uncommon for the curtain, under the effect of the wind or because of obstacles, either deflected from this vertical position when deployed in case of fire. Water is poorly, if at all, recovered in the channels, causing the flooding of local.

Le document FR-A-2 300 582 décrit un dispositif coupe-feu comprenant les caractéristiques telles qu'exposées dans le préambule de la revendication 1.Document FR-A-2 300 582 describes a device firebreak including features such as as set out in the preamble of claim 1.

Cependant, selon ce dispositif connu, en cas d'effondrement de l'une des parois du rideau, les deux parois de celui-ci s'effondrent ensemble, laissant ainsi l'incendie se propager librement.However, according to this known device, in the event collapse of one of the curtain walls, both walls of it collapse together, thus leaving the fire spread freely.

Le document FR-A-2 287 926 décrit également un rideau pare-feu d'une structure ne permettant pas non plus d'empêcher la propagation de l'incendie lorsque une partie de l'ossature de suspension du rideau s'effondre.Document FR-A-2 287 926 also describes a fire curtain of a structure not allowing either more to prevent the spread of the fire when a part of the curtain suspension structure collapses.

La présente invention a pour but de résoudre les inconvénients ci-dessus en proposant un dispositif formant rideau coupe-feu comprenant les caractéristiques techniques telles que définies dans la partie caractérisante de la revendication 1.The object of the present invention is to resolve the disadvantages above by proposing a device forming a fire curtain including the features techniques as defined in the section Characterizing of claim 1.

Divers avantages peuvent également être obtenus par le dispositif formant rideau coupe-feu tel que défini dans les revendications dépendantes 2 à 10.Various advantages can also be obtained by the fire curtain device such as defined in dependent claims 2 to 10.

Ces avantages peuvent être résumés comme suit :

  • Grâce au rideau coupe-feu à double parois, formant sensiblement une poche, et à l'arrosage des faces intérieures des parois, l'eau est récupérée à l'intérieur même du rideau, de sorte qu'il n'est plus nécessaire de prévoir au niveau de sol des rigoles de récupération et, en outre, tout risque d'inondation des locaux protégés est ainsi évité ;
  • Lorsque le fluide utilisé est un liquide tel que de l'eau, un volume prédéterminé de ce liquide est accumulé en partie inférieure du rideau et ce liquide emprisonné sur l'extrémité inférieure du rideau permet de lester cette dernière, assurant ainsi une bonne tension du rideau : l'étanchéité aux fumées ou aux gaz au niveau du sol est ainsi parfaite, le rideau ainsi lesté est maintenu vertical même en cas de surcharge horizontale due au vent et l'extrémité inférieure du rideau peut en outre épouser exactement le sol et les éventuels objets se trouvant accidentellement sous le rideau lorsque ce dernier est déployé ; et
  • la protection contre le feu est garantie même lorsque l'une des parties de la construction s'effondre, un rideau d'eau étant interposé entre le rideau restant et le feu.
These benefits can be summarized as follows:
  • Thanks to the double-walled fire curtain, substantially forming a pocket, and by sprinkling the interior faces of the walls, the water is collected inside the curtain itself, so that it is no longer necessary to provide recovery channels at ground level and, in addition, any risk of flooding of protected premises is thus avoided;
  • When the fluid used is a liquid such as water, a predetermined volume of this liquid is accumulated in the lower part of the curtain and this liquid trapped on the lower end of the curtain makes it possible to ballast the latter, thus ensuring good tension of the curtain: the impermeability to fumes or gases at ground level is thus perfect, the curtain thus ballasted is kept vertical even in the event of horizontal overload due to the wind and the lower end of the curtain can moreover exactly match the ground and the any objects accidentally under the curtain when it is deployed; and
  • protection against fire is guaranteed even when one of the parts of the construction collapses, a curtain of water being interposed between the remaining curtain and the fire.

En référence tout d'abord à la figure 1, un rideau coupe-feu 10 est fixé à une ossature supérieure 21 d'une construction 20.Referring first to Figure 1, a fire curtain 10 is attached to an upper frame 21 of a construction 20.

Cette dernière peut être par exemple un édifice de grandes dimensions à des fins industrielles ou destiné à recevoir un grand nombre de personnes.The latter can for example be a building large dimensions for industrial purposes or intended to receive a large number of people.

Elle comprend de manière connue une ossature supérieure 21 supportant la couverture.It comprises in known manner a framework upper 21 supporting the cover.

Le rideau 10 comprend deux parois 11 solidaires l'une de l'autre le long d'une extrémité inférieure 11d et des bords verticaux 11e du rideau 10.The curtain 10 comprises two integral walls 11 to each other along a lower end 11d and vertical edges 11e of the curtain 10.

Ces deux parois 11 comprennent des extrémités supérieures 11c fixées à l'ossature supérieure 21 sur toute la largeur du rideau 10. Le rideau 10 forme ainsi une poche accrochée à l'ossature supérieure 21.These two walls 11 include ends 11c upper fixed to the upper frame 21 on the entire width of the curtain 10. The curtain 10 thus forms a pocket attached to the upper frame 21.

Les parois 11 sont en toile de classes M1 ou M0 permettant de limiter la propagation des flammes et des gaz chauds ou inflammables et d'isoler thermiquement les deux parties de la construction séparées par le rideau 10.The walls 11 are made of fabric of classes M1 or M0 limiting the spread of flames and hot or flammable gases and thermally insulate the two parts of the construction separated by the curtain 10.

Ces parois sont constituées à titre d'exemples de tissus et de fibres de verre, de tissus en coton/polyester ou d'une armature en fibres de céramique continue. Ces toiles sont étanches aux liquides ou autorisent seulement un faible suintement du liquide dans le cas d'un tissu en coton/polyester.These walls are formed as examples fabrics and glass fibers, fabrics in cotton / polyester or ceramic fiber reinforcement keep on going. These fabrics are liquid tight or allow only a small amount of liquid to ooze in the case of a cotton / polyester fabric.

Des moyens d'arrosage 23 d'un fluide sur le rideau sont prévus sur l'ossature supérieure 21 de la construction 20.Watering means 23 for a fluid on the curtain are provided on the upper frame 21 of the construction 20.

Conformément à l'invention, ces moyens d'arrosage 22 sont adaptés à arroser par le fluide au moins une face intérieure 11a d'une paroi 11, c'est-à-dire l'une des faces 11a en vis-à-vis des deux parois 11.In accordance with the invention, these means 22 are suitable for watering by the fluid at minus an inner face 11a of a wall 11, that is to say one of the faces 11a facing the two walls 11.

Le fluide utilisé dans l'exemple décrit ci-après est de l'eau. Un autre liquide ou un gaz réfrigérant pourrait également être employé.The fluid used in the example described below is water. Another liquid or refrigerant gas could also be used.

Comme illustré à la figure 3, au moins un des bords verticaux 11e comprend à proximité de l'extrémité inférieure 11d du rideau 10, des moyens d'évacuation 12 du fluide issu des moyens d'arrosage 22.As illustrated in Figure 3, at least one of 11th vertical edges includes near the end lower 11d of the curtain 10, evacuation means 12 fluid from the sprinkler means 22.

Une paroi 26 de la construction 20, adjacente au bord vertical 11e du rideau 10, comprend des moyens de récupération 28 du fluide.A wall 26 of the construction 20, adjacent to the vertical edge 11e of the curtain 10, comprises means for fluid recovery 28.

Dans cet exemple, les moyens d'évacuation 12 sont constitués d'un orifice disposé à une hauteur prédéterminée au-dessus de l'extrémité inférieure 11d du rideau 10.In this example, the evacuation means 12 consist of an orifice arranged at a height predetermined above the lower end 11d of the curtain 10.

L'eau s'échappant par cet orifice 12 est récupérée dans les moyens de récupération 28 qui peuvent comprendre un dispositif de pompage 28 et éventuellement de recyclage de l'eau pour redistribuer celle-ci aux moyens d'arrosage 22.The water escaping through this orifice 12 is recovered in the recovery means 28 which can include a pumping device 28 and possibly recycling water to redistribute it to watering means 22.

Comme bien illustré à la figure 2, l'orifice d'évacuation 12 peut être situé à une hauteur égale à 250 mm environ au-dessus du sol 31 et de l'extrémité inférieure 11d du rideau 10, c'est-à-dire égale à environ 1/40ième de la hauteur totale du rideau, de sorte qu'un volume d'eau reste prisonnier à l'intérieur du rideau 10 à double parois 11.As illustrated in Figure 2, the orifice 12 can be located at a height equal to About 250 mm above the ground 31 and the end lower 11d of curtain 10, i.e. equal to about 1 / 40th of the total height of the curtain, so that a volume of water remains trapped inside curtain 10 with double walls 11.

Cette accumulation d'eau en partie inférieure du rideau 10 assure la stabilité de ce dernier et une bonne tension, ainsi que l'étanchéité au sol 31 d'une zone par rapport à une autre séparée par le rideau 10.This accumulation of water in the lower part of the curtain 10 ensures the stability of the latter and good tension, as well as the sealing on the ground 31 of an area by compared to another separated by the curtain 10.

En fin d'utilisation de ce rideau coupe-feu ou pour manoeuvrer celui-ci, on peut évacuer le volume d'eau emprisonné par une vanne électro-mécanique et une tuyauterie souple introduite dans les orifices d'évacuation 12 situés sur chaque bord latéral 11e du rideau 10.At the end of use of this fire curtain or to maneuver it, we can evacuate the volume of water trapped by an electro-mechanical valve and a flexible piping introduced into the orifices 12 located on each side edge 11e of the curtain 10.

Les moyens d'arrosage 22 comprennent deux séries de buses 30 disposées sur l'ossature supérieure 21 de la construction 20. Ces buses sont adaptées à arroser une face intérieure 11a respectivement de chaque paroi 11, indépendamment l'une de l'autre.The sprinkler means 22 include two series nozzles 30 arranged on the upper frame 21 of the construction 20. These nozzles are suitable for watering a inner face 11a respectively of each wall 11, independently of each other.

On peut obtenir l'irrigation de l'une ou l'autre des parois ou des deux simultanément.You can get irrigation from either walls or both simultaneously.

Les moyens d'arrosage 22 comprennent des tuyauteries 32 d'amenée d'eau équipées de buses réparties uniformément sur la largeur du rideau 10, c'est-à-dire le long de l'extrémité supérieure 11e du rideau 10.The sprinkler means 22 include water supply pipes 32 fitted with nozzles uniformly distributed over the width of the curtain 10, that is to say along the upper end 11e of the curtain 10.

Ces buses de projection 30 permettent de former un rideau d'eau ou une lame d'eau sur toute la superficie de la face intérieure 11a d'une toile 11.These projection nozzles 30 make it possible to form a curtain of water or a blade of water over the entire area of the inner face 11a of a fabric 11.

Cette irrigation intérieure par de l'eau provoque en cas d'incendie, une évaporation de l'eau assurant un mouvement de convection et un refroidissement des éléments intérieurs au rideau 10, tel que le système d'irrigation 30, 32 lui-même ou la partie d'ossature 21 supportant le rideau.This indoor irrigation with water causes water to evaporate in the event of a fire providing convective movement and cooling of the interior elements of the curtain 10, such as the irrigation system 30, 32 itself or the frame part 21 supporting the curtain.

Comme illustré à la figure 5, les deux parois 11 sont reliées par des bandes 13 formant entretoises et de longueur égale afin de maintenir les deux parois 11 parallèles l'une à l'autre.As illustrated in FIG. 5, the two walls 11 are connected by strips 13 forming spacers and equal length to maintain the two walls 11 parallel to each other.

Les bandes 13 peuvent être constituées de lanières en toile identique à celle utilisée pour les parois 11.The bands 13 can be made up of Canvas straps identical to that used for the walls 11.

Ces bandes 13 peuvent avoir une longueur comprise entre 0,5 et 1,5 mètre, réglant ainsi l'écartement entre les deux parois 11. De préférence, cet écartement est compris entre 0,8 et 1 mètre.These strips 13 can have a length between 0.5 and 1.5 meters, thus adjusting the spacing between the two walls 11. Preferably, this spacing is between 0.8 and 1 meter.

Les bandes 13 formant entretoises sont adaptées à se rompre sous une force de traction d'intensité sensiblement égale au poids d'une des deux parois 11.The bands 13 forming spacers are adapted to rupture under a tensile force of intensity substantially equal to the weight of one of the two walls 11.

Ainsi, si l'une des parties de l'ossature supérieure 21 s'effondre avec l'une des parois 11, les bandes 13 ont une résistance à la rupture calculée pour permettre le déchirement des bandes 13 et le maintien en place de l'autre paroi, du côté de la zone de la construction restant en place.So if one of the frame parts upper 21 collapses with one of the walls 11, the strips 13 have a breaking strength calculated for allow the tears 13 to be torn and the place of the other wall, on the side of the area of the construction remaining in place.

Ainsi, comme représenté aux figures 2 et 3, une zone de rupture 21a est aménagée dans l'ossature 21 permettant l'affaissement d'une des parties de la construction 20 en laissant les parties adjacentes stables. Le rideau 10 conforme à l'invention s'étend sensiblement sous cette zone de rupture 21a.Thus, as shown in Figures 2 and 3, a rupture zone 21a is arranged in the framework 21 allowing the subsidence of one part of the construction 20 leaving the adjacent parts stable. The curtain 10 according to the invention extends substantially below this rupture zone 21a.

Le rideau 10 comporte plusieurs bandes 13 réparties régulièrement sur sa longueur comme illustré à la figure 5 et plusieurs bandes 13 superposées sur la hauteur du rideau comme représenté à la figure 2.The curtain 10 has several strips 13 evenly distributed over its length as shown in Figure 5 and several bands 13 superimposed on the curtain height as shown in figure 2.

Chaque bande 13 formant entretoise comporte une pièce de liaison 14 adaptée à coulisser sur un câble ou ruban 15, ce câble ou ruban 15 ayant une première extrémité 15a fixée à l'extrémité inférieure 11d du rideau et une seconde extrémité 15b fixée à un enrouleur 23 solidaire de l'ossature supérieure 21 de la construction 20. Each strip 13 forming a spacer comprises a connecting piece 14 adapted to slide on a cable or ribbon 15, this cable or ribbon 15 having a first end 15a fixed to the lower end 11d of the curtain and a second end 15b fixed to a reel 23 secured to the upper frame 21 of the construction 20.

Lorsque le câble ou le ruban 15 est enroulé sur l'enrouleur 23, l'ensemble des bandes formant entretoise 13 sont pliées les unes sur les autres de sorte que les deux parois 11 sont repliées à proximité de l'ossature supérieure 21 de la construction 20.When the cable or ribbon 15 is wound on the reel 23, the set of bands forming a spacer 13 are folded over each other so that the two walls 11 are folded close to the frame upper 21 of construction 20.

De préférence, des plaques 24 de protection sont fixées à l'ossature supérieure 21 et s'étendent vers le sol 31 sur une hauteur suffisante pour masquer l'ensemble du rideau 10 lorsqu'il est en position repliée tel qu'illustré à la figure 4A. Ces plaques ont une longueur égale à celle du rideau, comprise entre 80 et 100 m et une hauteur égale à environ 0,5 m.Preferably, protective plates 24 are attached to the upper frame 21 and extend towards the ground 31 on a height sufficient to hide the entire curtain 10 when in position folded as shown in Figure 4A. These plates have a length equal to that of the curtain, between 80 and 100 m and a height of approximately 0.5 m.

Cette hauteur correspond sensiblement à l'encombrement du rideau 10 replié lorsque ce dernier a une hauteur d'environ 10 mètres en position déployée.This height corresponds substantially to the size of the curtain 10 folded back when the latter has a height of approximately 10 meters in the deployed position.

De même, des plaques de protection 25 sont solidaires des parois verticales 26 de la construction et s'étendent parallèlement au rideau 10, de chaque côté de celui-ci.Similarly, protective plates 25 are integral with the vertical walls 26 of the construction and extend parallel to the curtain 10, on each side of it.

Une zone 27 peut être délimitée par les plaques 25, la paroi verticale 26 adjacente à un bord 11e du rideau 10 et une seconde paroi latérale 26a parallèle à la première paroi verticale 26 afin de loger les mécanismes de commande d'arrosage et de récupération de l'eau.A zone 27 can be delimited by the plates 25, the vertical wall 26 adjacent to an edge 11e of the curtain 10 and a second side wall 26a parallel to the first vertical wall 26 in order to accommodate the sprinkler control and recovery mechanisms the water.

Ces plaques de protection 24 et 25 sont de préférence réalisées en un matériau coupe-feu de classe M0.These protective plates 24 and 25 are of preferably made of a class fire-resistant material M0.

Le fonctionnement va maintenant être décrit notamment en référence aux figures 4A à 4E.The operation will now be described in particular with reference to FIGS. 4A to 4E.

En cas d'incendie, le déploiement du rideau 10 est commandé soit manuellement, soit automatiquement, suite à un ordre donné par exemple par un détecteur de fumées. L'enrouleur 23 est alors entraíné en rotation, par un moteur (non représenté) par exemple et le câble ou ruban 15 est alors progressivement déroulé. Les bandes 13 coulissent au fur et à mesure sur le câble 15 de sorte que les parois 11 se déplient.In the event of a fire, the deployment of the curtain 10 is controlled either manually or automatically, following an order given for example by a fumes. The reel 23 is then rotated, by a motor (not shown) for example and the cable or ribbon 15 is then progressively unwound. The bands 13 slide progressively on the cable 15 so that the walls 11 unfold.

L'irrigation du rideau est alors commandée soit sur les deux faces intérieures 11a, soit seulement sur la face 11a de la paroi exposée au feu.The curtain irrigation is then controlled either on the two interior faces 11a, or only on the face 11a of the wall exposed to fire.

En cas de rupture de l'ossature 21 de la construction 20 dans la zone en feu, seule l'autre paroi 11 reste suspendue à la partie restant en place de la construction 10.If the frame 21 of the construction 20 in the burning zone, only the other wall 11 remains suspended from the remaining part of the construction 10.

Des moyens de commande, connus en eux-mêmes, sont adaptés à commander automatiquement la mise en marche des buses d'irrigation 30 projetant de l'eau sur cette paroi 11 maintenue en place, en alternant le fonctionnement des deux séries de buses 30.Control means, known in themselves, are suitable for automatically controlling the setting running irrigation nozzles 30 spraying water on this wall 11 held in place, alternating the operation of the two series of nozzles 30.

Le rideau conforme à l'invention permet donc d'assurer le compartimentage des édifices de grands volumes et de limiter ainsi de manière très efficace la propagation des incendies.The curtain according to the invention therefore allows compartmentalize tall buildings volumes and thus very effectively limit the spread of fire.

Bien entendu, de nombreuses modifications peuvent être apportées à l'exemple décrit ci-dessus sans sortir du cadre de l'invention, telle que définie dans les revendications.Of course, many modifications can be made to the example described above without depart from the scope of the invention, as defined in claims.
