Description

Système de clapet coupe-feu articulé avec étanchéité  Articulated fire damper system with sealing
et ensemble composé de deux tels systèmes  and set consisting of two such systems
La présente invention concerne le domaine de la lutte contre les incendies, notamment dans les bâtiments de haute sécurité tels que les centrales nucléaires, et plus particulièrement les clapets coupe-feu articulés et a pour objet un système de clapet coupe-feu articulé avec étanchéité intégrée. Elle a également pour objet un ensemble composé d'au moins deux tels systèmes. The present invention relates to the field of fire-fighting, in particular in high-security buildings such as nuclear power plants, and more particularly to articulated fire dampers and relates to an articulated fire damper system with integrated sealing. . It also relates to a set composed of at least two such systems.
On connaît le principe du clapet coupe-feu qui consiste à fermer ce dernier lorsque la température du flux gazeux le traversant dépasse une valeur déterminée de sorte à isoler instantanément les deux espaces séparés par ledit clapet, c'est-à-dire à empêcher tout flux gazeux de passer ou de circuler entre lesdits espaces via le clapet.  The principle of the fire damper is known which consists in closing the latter when the temperature of the gas stream passing through it exceeds a determined value so as to isolate instantly the two spaces separated by said valve, that is to say to prevent any gaseous flow to pass or circulate between said spaces via the valve.
On sait qu'un tel clapet coupe-feu articulé comprend une cage ou un caisson en forme de cadre ou de tunnel, généralement de section rectangulaire, carré ou circulaire, comprenant, dans son espace interne formant un passage traversant de flux gazeux, un volet ou une rangée de volets chacun de forme, ronde, rectangulaire ou carrée et monté pivotant dans ladite cage entre une position d'ouverture ou état ouvert dudit passage et une position de fermeture ou état fermé dudit passage.  It is known that such an articulated fire damper comprises a cage or box in the form of a frame or tunnel, generally of rectangular, square or circular section, comprising, in its internal space forming a through passage of gas flow, a flap or a row of flaps each of shape, round, rectangular or square and pivotally mounted in said cage between an open position or open state of said passage and a closed position or closed state of said passage.
Ce type de clapet coupe-feu articulé est généralement prévu pour être installé, dans une orientation verticale ou sensiblement verticale, soit en applique contre une ouverture traversant une cloison de séparation ou murale, soit en étant scellé ou fixé dans cette dernière ou dans l'ouverture d'un conduit d'air. D'autres clapets de ce type sont prévus pour être installé, dans une orientation horizontale ou sensiblement horizontale, dans un plancher.  This type of articulated fire damper is generally intended to be installed, in a vertical or substantially vertical orientation, either against an opening through a partition wall or wall, or by being sealed or fixed in the latter or in the opening of an air duct. Other valves of this type are intended to be installed in a horizontal or substantially horizontal orientation in a floor.
Un ou plusieurs ressorts assurent généralement la fermeture automatique du clapet coupe-feu articulé en étant commandés par un mécanisme de commande, généralement du type fusible thermique qui fond au-delà d'une certaine température, ce qui a pour effet de libérer le ou les ressorts qui actionnent alors la fermeture du clapet. D'autres mécanismes de commande ou de déclenchement connus équipent les clapets coupe-feu actuels ou complètent lesdits fusibles thermiques, tels que des électroaimants ou des servomoteurs. Le réarmement du clapet coupe-feu est généralement effectué manuellement mais peut être automatique notamment lorsque le clapet coupe-feu articulé est motorisé, par exemple au moyen d'un servomoteur. One or more springs generally provide for the automatic closing of the hinged firestop valve being controlled by a control mechanism, generally of the thermal fuse type that melts beyond a certain temperature, which has the effect of releasing the one or more springs which then actuate the closing of the valve. Other known control or triggering mechanisms equip the current fire dampers or supplement said thermal fuses, such as electromagnets or servomotors. The reset of the fire damper is generally performed manually but may be automatic, especially when the articulated fire damper is motorized, for example by means of a servomotor.
La cage et les volets sont usuellement réalisés en acier et recouverts d'un matériau réfractaire tel qu'un silicate de calcium qui assure une isolation thermique et une stabilité maximale.  The cage and flaps are usually made of steel and covered with a refractory material such as calcium silicate which provides thermal insulation and maximum stability.
D'autre part, les clapets coupe-feu actuels sont généralement équipés de joints intumescents qui sont situés sur le pourtour ou le bord périphérique des lames ou des volets. Ces joints se dilatent lorsque la température s'élève, généralement au-delà de 140°C, ce qui a pour effet de former une barrière d'étanchéité avec pression entre le volet et la face interne de la cage.  On the other hand, current fire dampers are generally equipped with intumescent seals which are located on the periphery or the peripheral edge of the blades or shutters. These joints expand when the temperature rises, generally above 140 ° C, which has the effect of forming a sealing barrier with pressure between the flap and the inner face of the cage.
Toutefois, ce type de joint a tendance fréquemment à se dégrader dans le temps, ce qui ne permet pas de répondre aux normes ou aux critères requis actuels dans ce domaine, notamment pour des applications dans des bâtiments de haute sécurité tels que les centrales nucléaires, qui exigent des phases de fermeture du clapet coupe feu articulé sur un grand nombre de cycles de fonctionnement (généralement environ 500 cycles).  However, this type of joint frequently tends to degrade over time, which does not meet the current standards or criteria required in this area, especially for applications in high security buildings such as nuclear power plants, which require closing stages of the fire damper articulated over a large number of operating cycles (generally about 500 cycles).
La présente invention a pour but de pallier ces inconvénients en proposant un système de clapet coupe-feu articulé avec étanchéité intégrée, permettant d'obtenir une grande efficacité de l'étanchéité du système à l'état fermé en étant capable de répondre aux normes actuelles ou aux critères requis, y compris les plus sévères, et notamment ceux régissant la réglementation en matière de sécurité dans les bâtiments de haute sécurité tels que par exemple les bâtiments de centrales nucléaires.  The present invention aims to overcome these disadvantages by proposing an articulated fire damper system with integrated sealing, to obtain a high efficiency of sealing the system in the closed state by being able to meet current standards or the required criteria, including the most stringent criteria, including those governing safety regulations in high security buildings such as nuclear power plant buildings.
A cet effet, le système de clapet coupe-feu articulé avec étanchéité intégrée, selon la présente invention, qui comprend une cage en forme de cadre carré ou rectangulaire comprenant deux premières faces internes opposées parallèles entre elles et deux secondes faces internes opposées perpendiculaires à ces dernières, ladite cage comportant dans son espace interne, formant un passage susceptible d'être traversé par un flux gazeux, un volet ou, le cas échéant, une rangée d'une pluralité de volets, le ou chaque volet, de forme carrée ou rectangulaire, d'une part, étant apte à être monté pivotant autour d'un axe de pivotement reliant les deux premières faces internes, entre une position de fermeture ou état fermé et une position d'ouverture ou état ouvert dudit passage, et, d'autre part, présentant chacun deux grandes faces opposées reliées par deux premiers côtés opposés et parallèles au(x)dit(s) axe(s) de pivotement et par deux seconds côtés opposés perpendiculaires auxdits premiers côtés et, le cas échéant, parallèles à l'axe longitudinal de ladite rangée, se caractérise essentiellement en ce que la cage comprend en outre deux premières plaques de contact et d'étanchéité allongées, de préférence minces, s'étendant chacune, parallèlement au(x)dit(s) axes, sur l'une des secondes faces internes et en ce que le ou chaque volet comprend deux secondes plaques de contact et d'étanchéité allongées, de préférence minces, s'étendant chacune le long de l'un des premiers côtés, chaque seconde plaque du volet étant apte, à l'état fermé, à coopérer, par contact de surface, avec l'une des deux premières plaques, le cas échéant chaque seconde plaque de chaque volet de ladite rangée étant apte, à l'état fermé, à coopérer, selon l'emplacement du volet concerné, par contact de surface, soit avec l'une des deux premières plaques, soit avec l'une des secondes plaques du volet adjacent, ce afin d'assurer une étanchéité renforcée et durable du système à l'état de fermeture.

Les figures montrent un système de clapet coupe-feu articulé avec étanchéité intégrée, selon la présente invention, comprenant une cage 1 en forme de cadre carré ou rectangulaire comprenant deux premières faces internes la opposées parallèles entre elles et deux secondes faces internes lb opposées perpendiculaires à ces dernières, ladite cage 1 comportant dans son espace interne, formant un passage susceptible d'être traversé par un flux gazeux, un volet 2 (figures 1, 2, 3, 4) ou, le cas échéant, une rangée d'une pluralité de volets 2 (figures 5, 6, 7, 8, 9, 10), le ou chaque volet 2, de forme carrée ou rectangulaire, d'une part, étant apte à être monté pivotant autour d'un axe de pivotement 2a reliant les deux premières faces internes, entre une position de fermeture ou état fermé et une position d'ouverture ou état ouvert dudit passage, et, d'autre part, présentant deux grandes faces opposées reliées par deux premiers côtés 2b opposés et parallèles au(x)dit(s) axe(s) de pivotement 2a et par deux seconds côtés 2c opposés perpendiculaires auxdits premiers côtés et, le cas échéant, parallèles à l'axe longitudinal de ladite rangée.  The figures show a hinged firestop valve system with integrated sealing, according to the present invention, comprising a cage 1 in the form of a square or rectangular frame comprising two first internal faces the opposite parallel to each other and two second inner faces lb opposite perpendicular to the latter, said cage 1 having in its internal space, forming a passage capable of being traversed by a gas flow, a flap 2 (FIGS. 1, 2, 3, 4) or, where appropriate, a row of a plurality flap 2 (Figures 5, 6, 7, 8, 9, 10), the or each shutter 2, of square or rectangular shape, on the one hand, being adapted to be pivotally mounted about a pivot axis 2a connecting the first two internal faces, between a closed or closed position and an open position or open state of said passage, and, on the other hand, having two large opposite faces connected by two opposite first sides 2b and parallel s to said pivot axis (s) 2a and two opposite second sides 2c perpendicular to said first sides and, where appropriate, parallel to the longitudinal axis of said row.
Conformément à la présente invention, la cage 1 comprend en outre deux premières plaques 3a de contact et d'étanchéité allongées, de préférence minces, s 'étendant chacune, parallèlement au(x)dit(s) axes, sur l'une des secondes faces internes lb. En outre, le ou chaque volet 2 comprend deux secondes plaques 4a de contact et d'étanchéité allongées, de préférence minces, s'étendant chacune le long de l'un des premiers côtés 2b.  According to the present invention, the cage 1 further comprises two elongated, preferably thin, first elongated contact and sealing plates 3 each extending parallel to said axis on one of the seconds. internal faces lb. In addition, the or each flap 2 comprises two elongate, preferably thin, elongated contact and sealing plates 4a each extending along one of the first sides 2b.
Le cas échéant, on entendra, selon la présente invention, par premières ou secondes plaques minces, des premières ou secondes plaques de faible épaisseur. Par exemple, mais non limitativement, chaque première ou seconde plaque mince, plus particulièrement métallique, de préférence en acier, peut présenter, de préférence, une épaisseur comprise entre 0,2 mm et 0,5 mm.  Where appropriate, it will be understood according to the present invention, by first or second thin plates, first or second thin plates. For example, but not exclusively, each first or second thin plate, more particularly metal, preferably steel, may have a thickness preferably between 0.2 mm and 0.5 mm.
Toujours conformément à la présente invention, chaque seconde plaque 4a du volet 2 est apte, à l'état fermé, à coopérer, par contact de surface, avec l'une des deux premières plaques 3a. Le cas échéant, lorsque le système comprend une rangée d'une pluralité de volets 2, chaque seconde plaque 4a de chaque volet 2 est apte, à l'état fermé, selon l'emplacement du volet 2 concerné, à coopérer, par contact de surface, soit avec l'une des deux premières plaques 3a, soit avec l'une des secondes plaques 4a du volet 2 adjacent. Still in accordance with the present invention, each second plate 4a of the shutter 2 is capable, in the closed state, of cooperating, by surface contact, with one of the first two plates 3a. Where appropriate, when the system includes a row of a plurality of shutters 2, each second plate 4a of each shutter 2 is capable, in the closed state, depending on the location of the shutter 2 concerned, to cooperate, by surface contact, with one of the two first plates 3a, or with the one of the second plates 4a of the adjacent flap 2.
Le système selon la présente invention a donc pour effet, grâce aux premières et secondes plaques 3a et 4a et à leur coopération par contact de leurs surfaces respectives, de préférence planes, à l'état fermé du système, d'assurer ou de garantir une étanchéité renforcée et durable du système.  The system according to the present invention therefore has the effect, thanks to the first and second plates 3a and 4a and their cooperation by contact of their respective surfaces, preferably flat, in the closed state of the system, to ensure or guarantee a reinforced and durable sealing of the system.
On comprendra que dans le cas où un tel système comprend une rangée d'une pluralité de volets 2, lorsque celle-ci comprend deux volets 2, l'un des deux seconds éléments 4a de chaque volet 2 coopère avec l'une des premières plaques 3a et l'autre seconde plaque 4a coopère avec l'une des secondes plaques de l'autre volet 2. Lorsque la rangée comprend au moins trois volets (notamment figures 5, 6, 7 et 10), c'est-à-dire deux volets 2 d'extrémité et au moins un volet 2 intermédiaire placé entre lesdits volets 2 d'extrémité, l'une des deux secondes plaques 4a de chaque volet 2 d'extrémité coopère avec l'une des deux premières plaques 3a, tandis que l'autre seconde plaque 4a coopère avec l'une des secondes plaques 4a du volet 2 intermédiaire adjacent. D'autre part, toujours dans le cas où la rangée comprend au moins trois volets 2, chaque seconde plaque 4a du ou de chaque volet 2 intermédiaire coopère avec l'une des secondes plaques 4a du volet 2 adjacent (figure 9a et 9b).  It will be understood that in the case where such a system comprises a row of a plurality of flaps 2, when it comprises two flaps 2, one of the two second elements 4a of each flap 2 cooperates with one of the first plates 3a and the other second plate 4a cooperates with one of the second plates of the other flap 2. When the row comprises at least three flaps (in particular Figures 5, 6, 7 and 10), that is to say two end flaps 2 and at least one intermediate flap 2 placed between said end flaps 2, one of the two second plates 4a of each end flap 2 cooperates with one of the first two plates 3a, while the other second plate 4a cooperates with one of the second plates 4a of the adjacent intermediate flap 2. On the other hand, still in the case where the row comprises at least three flaps 2, each second plate 4a of the or each intermediate flap 2 cooperates with one of the second plates 4a of the flap 2 adjacent (Figure 9a and 9b).
Dans un mode de réalisation préférentiel de la présente invention, chaque première plaque 3a, qui s'étend le long de la seconde face interne lb concernée, peut être inclinée latéralement par rapport à cette dernière de sorte à ménager un premier espace entre chaque première plaque 3a et la seconde face interne lb associée ou correspondante et chaque seconde plaque 4a peut être inclinée latéralement par rapport au premier côté 2b du volet 2 le long duquel il s'étend longitudinalement de sorte à ménager un second espace entre chaque seconde plaque 4a et le premier côté 2b associé ou correspondant (figure 9a et 9b). En outre, d'une part, les deux premières plaques 3a peuvent être montées tête bêche, ou orientées dans une direction d'inclinaison opposée, l'une par rapport à l'autre et, d'autre part, les deux secondes plaques 4a inclinées du ou de chaque volet 2 peuvent être montées tête bêche, ou orientées dans une direction d'inclinaison opposée l'une par rapport à l'autre (notamment figures 3a, 3b et 7). In a preferred embodiment of the present invention, each first plate 3a, which extends along the second internal face 1b concerned, may be laterally inclined relative to the latter so as to provide a first space between each first plate 3a and the second associated or corresponding inner face lb and each second plate 4a can be inclined laterally with respect to the first side 2b of the flap 2 along which it extends longitudinally so as to provide a second space between each second plate 4a and the first side 2b associated or corresponding (Figure 9a and 9b). In addition, on the one hand, the first two plates 3a can be mounted head to tail, or oriented in a direction of opposite inclination, relative to each other and, secondly, the two second plates 4a inclined or each flap 2 can be mounted head to tail, or oriented in a direction of inclination opposite to each other (in particular Figures 3a, 3b and 7).
De préférence, les premières plaques 3a et/ou les secondes plaques 4a peuvent consister chacune en une plaque ou une lame métallique mince. De préférence chaque plaque ou lame métallique 3a ou 4a peut être souple, flexible ou semi-rigide.  Preferably, the first plates 3a and / or the second plates 4a may each consist of a plate or a thin metal blade. Preferably each plate or metal blade 3a or 4a may be flexible, flexible or semi-rigid.
Ainsi, dans une première forme de réalisation de la coopération permettant d'assurer l'étanchéité, chaque première plaque 3a de la cage 1 et chaque seconde plaque 4a du ou de chaque volet 2 peuvent être positionnées et orientées (figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) de manière que, à l'état fermé, chaque première plaque 3a puisse être insérée dans le second espace ménagé par la seconde plaque 4a concernée et, réciproquement, que cette dernière puisse être insérée dans le premier espace ménagé par la première plaque 3a concernée, ce avec mise en contact de la face interne de chaque première plaque 3a avec la face interne de la seconde plaque 4a concernée. D'autre part, le cas échéant, lorsque le système comprend une rangée d'une pluralité de volets 2 de la rangée de volets 2, chaque seconde plaque 4a de chaque volet 2 peut être positionnée et orientée de manière que, à l'état fermé, chaque seconde plaque 4a puisse être insérée dans le second espace ménagé par l'autre seconde plaque 4a adjacente et réciproquement, ce avec mise en contact entre elles des deux faces internes desdites secondes plaques 4a concernées adjacentes (figure 9a).  Thus, in a first embodiment of the cooperation making it possible to seal, each first plate 3a of the cage 1 and each second plate 4a of the or each shutter 2 can be positioned and oriented (FIGS. 1, 2, 3 , 4, 5, 6, 7, 8, 9, 10) so that, in the closed state, each first plate 3a can be inserted into the second space provided by the second plate 4a in question and, conversely, that the latter can be inserted into the first space provided by the first plate 3a concerned, this with contact of the inner face of each first plate 3a with the inner face of the second plate 4a concerned. On the other hand, where appropriate, when the system comprises a row of a plurality of flaps 2 of the row of flaps 2, each second plate 4a of each flap 2 can be positioned and oriented so that, in the state closed, each second plate 4a can be inserted into the second space formed by the other adjacent second plate 4a and reciprocally, this bringing into contact with each other the internal faces of said adjacent second adjacent plates 4a (FIG. 9a).
Dans une seconde forme de réalisation de la coopération permettant d'assurer l'étanchéité, chaque première plaque 3a de la cage 1 et chaque seconde plaque 4a du ou de chaque volet 2 peuvent être positionnées et orientées de manière que, à l'état fermé, la face externe de chaque première plaque 3a puisse être mise en contact avec la face externe de la seconde plaque 4a concernée. D'autre part, le cas échéant, lorsque le système comprend une rangée d'une pluralité de volets 2, chaque seconde plaque 4a de chaque volet 2 peut être positionnée et orientée de manière que, à l'état fermé, la face externe de chaque seconde plaque 4a puisse être mise en contact avec la face externe de la seconde plaque 4a concernée adjacente (figure 1 1).  In a second embodiment of the cooperation for sealing, each first plate 3a of the cage 1 and each second plate 4a of the or each shutter 2 can be positioned and oriented so that, in the closed state the outer face of each first plate 3a can be brought into contact with the external face of the second plate 4a concerned. On the other hand, where appropriate, when the system comprises a row of a plurality of flaps 2, each second plate 4a of each flap 2 can be positioned and oriented so that, in the closed state, the outer face of each second plate 4a can be brought into contact with the external face of the adjacent second plate 4a (FIG. 11).
On entendra par inclinée latéralement le fait, de préférence, d'incliner chaque première plaque 3a, respectivement chaque seconde plaque 4a, par rapport à la seconde face interne lb correspondante, respectivement par rapport à la surface du premier côté 2b correspondant, en maintenant l'axe longitudinal de chaque première plaque 3a, respectivement de chaque seconde plaque 4a, parallèle ou sensiblement parallèle à la seconde face interne lb correspondante, respectivement à la surface du premier côté 2b correspondant. By laterally inclined it will preferably be understood to incline each first plate 3a, respectively each second plate 4a, relative to the corresponding second internal face 1b respectively relative to the surface of the corresponding first side 2b, maintaining the longitudinal axis of each first plate 3a, respectively of each second plate 4a, parallel or substantially parallel to the corresponding second internal face lb, respectively to the surface of the corresponding first side 2b.
De préférence le système selon la présente invention peut comprendre deux premiers profilés 3 allongés et droits, présentant chacun une section transversale ou un profil en V, dont l'une des deux ailes ou aile de fixation 3b peut être fixée sur l'une des secondes faces internes lb et l'autre aile peut former l'une des deux premières plaques 3a.  Preferably the system according to the present invention may comprise two first elongate and straight sections 3, each having a cross section or a V-shaped profile, one of the two wings or fixing wing 3b may be fixed on one of the seconds inner faces lb and the other wing can form one of the first two plates 3a.
Chaque premier profilé 3 en V peut être ouvert avec un angle interne aigu (figure 3 a) ou obtus (figure 3b).  Each first section 3 in V can be opened with an acute (Figure 3a) or obtuse (Figure 3b) internal angle.
Dans une autre première forme de réalisation du maintien et de la fixation de chaque seconde plaque 4a sur le volet 2 correspondant, la présente invention peut comprendre au moins deux plaques ou panneaux 4 se prolongeant chacun(e) à l'un de ses côtés par une aile inclinée et chaque grande face du ou de chaque volet 2 peut être recouverte par l'un(e) desdit(e)s plaques ou panneaux 4 de sorte que l'aile inclinée de ce dernier s'étende longitudinalement le long de l'un des premiers côtés 2b du volet 2 correspondant en formant l'une des secondes plaques 4a (notamment figures 1, 3a, 3b, 5, 9a, 10, 1 1).  In another first embodiment of the holding and fixing of each second plate 4a on the corresponding flap 2, the present invention may comprise at least two plates or panels 4 each extending to one of its sides by an inclined wing and each large face of the or each shutter 2 may be covered by one of said plates or panels 4 so that the inclined wing of the latter extends longitudinally along the one of the first sides 2b of the corresponding shutter 2 forming one of the second plates 4a (in particular FIGS. 1, 3a, 3b, 5, 9a, 10, 1 1).
Dans une seconde forme de réalisation du maintien et de la fixation de chaque seconde plaque 4a sur le volet 2 correspondant, le système selon la présente invention peut comprendre au moins deux seconds profilés 4' en V dont l'une des ailes 4b de chaque second profilé en V peut former une aile support fixée longitudinalement par sa face externe sur l'un des premiers côtés 2b du volet 2 concerné ou, dans une variante non représentée, sur l'une des grandes faces de ce dernier, tandis que l'autre aile de chaque second profilé 4' en V peut former l'une des secondes plaques 4a (figure 9b). Chaque second profilé 4' en V peut être ouvert, soit avec un angle interne aigu de sorte que l'aile support puisse être fixée sur l'un des premiers côtés 2b du volet 2 (figure 9b), soit, dans ladite variante, avec un angle interne obtus de sorte que l'aile support puisse être fixée sur l'une des grandes faces du volet 2 concerné.  In a second embodiment of holding and fixing each second plate 4a on the corresponding shutter 2, the system according to the present invention may comprise at least two second V-shaped sections 4 ', one of which wings 4b of each second V-shaped profile can form a support wing fixed longitudinally by its outer face on one of the first sides 2b of the component 2 concerned or, in a variant not shown, on one of the large faces of the latter, while the other wing of each second section 4 'V can form one of the second plates 4a (Figure 9b). Each second section 4 'in V can be open, either with an acute internal angle so that the support wing can be fixed on one of the first sides 2b of the shutter 2 (FIG. 9b), or, in this variant, with an internal angle obtuse so that the support wing can be fixed on one of the large faces of the flap 2 concerned.
De préférence, afin de renforcer encore l'étanchéité à l'état fermé, le système selon la présente invention peut comprendre en outre deux faces de contact et d'étanchéité additionnelles 5a droites et allongées fixées chacune en vis-à-vis l'une par rapport à l'autre en étant rapportée et fixée sur l'une des premières faces internes la perpendiculairement aux secondes faces internes lb de la cage 1 de sorte que chaque axe de pivotement 2a du ou des volets 2 puisse traverser les faces de contact et d'étanchéité 5a qui comportent à cet effet des trous 5c et que chaque second côté 2c du ou de chaque volet 2 puisse être, à l'état fermé, en contact d'étanchéité avec l'une des faces de contact et d'étanchéité 5a formant une surépaisseur de contact sur la première face interne la correspondante. Preferably, in order to further reinforce the tightness in the closed state, the system according to the present invention may furthermore comprise two additional elongate and elongate contact and sealing faces 5a each fixed opposite one another. compared to each other by being reported and fixed on one of the first internal faces perpendicular to the second internal faces lb of the cage 1 so that each pivot axis 2a of the flap or 2 can pass through the contact and sealing faces 5a which comprise for this purpose holes 5c and that each second side 2c of the or each shutter 2 may be, in the closed state, in sealing contact with one of the contact and sealing faces 5a forming a contact excess on the first face internal correspondent.
A cet effet, le système selon la présente invention peut comprendre deux profilés additionnels 5, de préférence métalliques, allongés et droits et présentant chacun une section transversale globalement en Ω, en U ou en C comprenant au moins une aile latérale, de préférence deux ailes latérales 5b, permettant sa fixation sur l'une des deux premières faces internes la de la cage 1 et une aile centrale reliée à la ou auxdites ailes latérales 5b, la face externe de l'aile centrale 5c de chaque profilé additionnel 5 formant alors l'une des deux faces de contact et d'étanchéité additionnelles 5a (notamment, figures 1, 5, 8 et 10).  For this purpose, the system according to the present invention may comprise two additional profiles 5, preferably metal, elongated and straight and each having a cross section generally Ω, U or C comprising at least one side wing, preferably two wings 5b, allowing its attachment to one of the first two internal faces of the cage 1 and a central wing connected to the or said lateral wings 5b, the outer face of the central wing 5c of each additional section 5 forming the one of the two additional contact and sealing faces 5a (in particular, FIGS. 1, 5, 8 and 10).
On comprendra que dans le cas où le système selon la présente invention ne comprend pas ces deux faces de contact et d'étanchéité additionnelles 5a, l'étanchéité, à l'état fermé, entre les seconds côtés 2c du ou de chaque volet 2 peut être réalisée directement par contact de surface entre la face externe de chaque second côté 2c et la première face interne la concernée de la cage 1.  It will be understood that in the case where the system according to the present invention does not comprise these two additional contact and sealing faces 5a, sealing, in the closed state, between the second sides 2c of the or each flap 2 may be made directly by surface contact between the outer face of each second side 2c and the first inner face of the concerned cage 1.
La présente invention a également pour objet un ensemble composé de deux tels systèmes de clapet coupe-feu articulés avec étanchéité intégrée selon la présente invention (figure 10).  The present invention also relates to an assembly consisting of two such articulated fire damper systems with integrated sealing according to the present invention (Figure 10).
Conformément à la présente invention, les deux systèmes sont montés en série de sorte à former une juxtaposition d'un premier système et d'un second système avec un espace de passage unique du flux gazeux commun auxdits systèmes. Par ailleurs, les deux systèmes sont équipés chacun d'un mécanisme de commande indépendant, non représenté, de sorte que le premier système puisse être commandé en fonctionnement normal et que le second système, formant un système de secours, puisse être commandé, en cas de dysfonctionnement du premier système, pour prendre le relai de ce dernier.  According to the present invention, the two systems are connected in series so as to form a juxtaposition of a first system and a second system with a single passage space of the gas flow common to said systems. Moreover, the two systems are each equipped with an independent control mechanism, not shown, so that the first system can be controlled in normal operation and the second system, forming a backup system, can be controlled, in case malfunction of the first system, to take the relay of the latter.
Un tel ensemble ou un système selon la présente invention peut être prévu pour être installé, par exemple, en applique contre une ouverture traversant une cloison séparant deux espaces ou deux pièces d'un bâtiment, notamment un bâtiment de haute sécurité tel qu'une centrale nucléaire, soit, par exemple, en étant fixé ou scellé dans ladite ouverture ou dans l'ouverture d'un conduit d'air, ou encore, dans une orientation horizontale ou sensiblement horizontale, par exemple dans un plancher. Such an assembly or a system according to the present invention may be provided to be installed, for example, applied against an opening through a partition separating two spaces or two rooms of a building, in particular, a high security building such as a nuclear power plant, or, for example, by being fixed or sealed in said opening or in the opening of an air duct, or else in a horizontal or substantially horizontal orientation, for example in a floor.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
