Description

L'invention propose un exutoire de désenfumage qui est agencé sur le toit d'un bâtiment.The invention proposes a smoke evacuation outlet which is arranged on the roof of a building.

L'invention propose plus particulièrement un exutoire de désenfumage, du type comportant une costière périphérique d'axe globalement vertical qui est prévue pour être agencée dans un logement complémentaire du toit d'un bâtiment et qui délimite un canal d'évacuation reliant l'intérieur du bâtiment avec l'extérieur, du type comportant au moins un ouvrant qui est monté mobile par rapport à la costière entre une position fermée d'obturation du canal d'évacuation, et au moins une position d'ouverture au moins partielle du canal d'évacuation, et du type comportant au moins un volet pare-vent qui s'étend verticalement vers le haut au-delà d'un bord supérieur de la costière de sorte à prolonger le canal d'évacuation vers le haut, au moins sur un côté.The invention more particularly proposes a smoke evacuation outlet, of the type comprising a circumferential curb of generally vertical axis which is intended to be arranged in a complementary housing of the roof of a building and which delimits an evacuation channel connecting the interior. of the building with the outside, of the type comprising at least one opening which is movably mounted relative to the curb between a closed position of closing the discharge channel, and at least one at least partial opening position of the duct. evacuation, and of the type comprising at least one windshield which extends vertically upwards beyond an upper edge of the curb so as to extend the evacuation channel upwards, at least on a side.

Lors d'un incendie, il est nécessaire d'évacuer les fumées d'un local pour que les personnes qui se trouvent à l'intérieur puissent respirer et/ou pour faciliter l'intervention des secours.During a fire, it is necessary to evacuate the smoke from a room so that the people who are inside can breathe and / or to facilitate the intervention of the rescue.

Dans les grands locaux que sont les usines et les hangars, cette fonction d'évacuation des fumées est assurée par un ou plusieurs exutoires de désenfumage qui délimitent chacun un canal par lequel la fumée est susceptible de sortir.In large premises such as factories and sheds, this smoke evacuation function is provided by one or more smoke evacuation outlets which each delimit a channel through which the smoke is likely to exit.

Un exutoire de désenfumage conventionnel comporte au moins un ouvrant qui est monté articulé entre une position de fermeture du canal de sortie dans laquelle la fumée ne peut pas s'évacuer du bâtiment, et une position d'ouverture du canal d'évacuation permettant l'évacuation de la fumée.A conventional smoke evacuation outlet comprises at least one opening which is articulated between a closed position of the outlet channel in which the smoke can not escape from the building, and an open position of the evacuation channel allowing the evacuation of smoke.

L'exutoire de désenfumage peut aussi avoir une fonction d'aérateur pour le bâtiment. Pour cela, l'ouvrant est susceptible d'occuper une positon intermédiaire dans laquelle l'ouverture du canal d'évacuation est plus ou moins importante.The smoke evacuation outlet can also act as an aerator for the building. For this, the opening is likely to occupy an intermediate position in which the opening of the evacuation channel is more or less important.

L'ouvrant est mis en mouvement entre ses positions d'ouverture et de fermeture du canal d'évacuation par un vérin du type hydropneumatique, pneumatique ou électrique. La course du vérin, ainsi que l'architecture de l'exutoire de désenfumage limitent généralement l'amplitude du mouvement de l'ouvrant qui est alors généralement comprise entre 90° et 140°The opening is set in motion between its open and closed positions of the evacuation channel by a cylinder of the hydropneumatic, pneumatic or electric type. The stroke of the jack, as well as the architecture of the smoke evacuation outlet generally limit the amplitude of the movement of the opening which is then generally between 90 ° and 140 °

L'efficacité de l'exutoire de désenfumage dépend aussi des conditions atmosphériques extérieures. Ainsi elle est améliorée en cas de vent. Cependant, lorsque l'ouvrant est en position d'ouverture du canal d'évacuation, et pour certaines orientations du vent par rapport à l'exutoire de désenfumage, l'ouvrant a un effet inverse à celui souhaité car il forme un obstacle au vent et qui génère une surpression localisée au niveau de la sortie du canal d'évacuation qui est supérieure à la pression qui règne à l'intérieur du local et qui empêche alors l'évacuation des fumées.The efficiency of the smoke extraction outlet also depends on external atmospheric conditions. So it is improved in case of wind. However, when the opening is in the open position of the evacuation channel, and for some wind directions relative to the smoke evacuation outlet, the opening has the opposite effect to that desired because it forms an obstacle to the wind and which generates a localized overpressure at the outlet of the discharge channel which is greater than the pressure that prevails inside the room and which then prevents the evacuation of fumes.

Pour éviter cet effet, il a été proposé d'augmenter la course de l'ouvrant à environ 180° de sorte que l'ouvrant, en position d'ouverture du canal d'évacuation, soit parallèle au toit du bâtiment et donc pour qu'il ne constitue plus un obstacle au vent.To avoid this effect, it has been proposed to increase the opening of the opening to about 180 ° so that the opening, in the open position of the evacuation channel, is parallel to the roof of the building and therefore for it no longer constitutes an obstacle to the wind.

Cette solution est difficilement réalisable pour les exutoires de désenfumage qui sont aptes à se refermer une fois l'incendie éteint. En effet, les moyens de commande et de mise en mouvement de l'ouvrant consistent généralement en des câbles de traction dont l'efficacité est limitée voire impossible lorsque l'angle d'ouverture est proche de 180°.This solution is difficult to achieve for smoke evacuation outlets that are able to close once the fire extinguished. Indeed, the means for controlling and moving the opening generally consist of traction cables whose effectiveness is limited or impossible when the opening angle is close to 180 °.

Pour réduire l'effet de surpression créé par l'ouvrant, il a aussi été proposé de munir l'exutoire de désenfumage de volets fixes formant pare-vent qui s'étendent verticalement au-delà du bord extérieur de l'exutoire de désenfumage de manière à prolonger le canal d'évacuation, et qui entourent celui-ci, à la manière d'une cheminée.To reduce the effect of overpressure created by the opening, it has also been proposed to provide the smoke evacuation outlet with fixed shutters forming a windshield that extend vertically beyond the outer edge of the smoke evacuation outlet. in order to extend the drainage channel, and surround it, in the manner of a chimney.

L'ouvrant est mobile à l'intérieur de cette "cheminée" de sorte qu'il ne peut plus faire barrière au vent, quelle que soit l'orientation du vent.The opening is mobile inside this "chimney" so that it can no longer be a barrier to the wind, whatever the direction of the wind.

Cependant, un tel agencement de l'exutoire de désenfumage s'avère relativement disgracieux sur le toit du bâtiment. Par ailleurs, des dépôts tels que la neige ou des feuilles, peuvent s'accumuler dans cette cheminée, et ils gênent alors l'ouverture de l'ouvrant. Il est alors nécessaire de supprimer les détritus, ce qui nécessite l'intervention d'une personne qui doit alors monter sur le toit du bâtiment, s'exposant au risque d'une chute. De plus, sous l'action du vent, les volets peuvent provoquer des bruits aérodynamiques nuisibles.However, such an arrangement of the smoke evacuation outlet is relatively unsightly on the roof of the building. Moreover, deposits such as snow or leaves, can accumulate in this chimney, and they interfere with the opening of the opening. It is then necessary to remove litter, which requires the intervention of a person who must then climb on the roof of the building, exposing himself to the risk of a fall. In addition, under the action of the wind, the flaps can cause harmful aerodynamic noise.

Les documents DE-A-25.43.979, DE 637 028 C, DE 578 247 C, et DE 29 612 188 U décrivent des exutoires de désenfumage comportant des volets pare-vent qui sont montés mobiles par rapport à la costière entre une position escamotée et une position déployée dans laquelle ils prolongent le canal d'évacuation et qui sont entraînés vers leur position déployée par l'ouvrant.Documents DE-A-25.43.979, DE 637 028 C, DE 578 247 C, and DE 29 612 188 U describe smoke evacuation outlets comprising wind flaps which are mounted movable relative to the curb between a retracted position. and an extended position in which they extend the evacuation channel and are driven to their deployed position by the opening.

Ainsi, quelque soit la position d'ouverture de l'ouvrant, les volets pare-vent sont eux aussi dans une position déployée. L'efficacité de l'évacuation des fumées ou de l'aération de l'intérieur du bâtiment peut alors être réduite lorsque l'ouvrant est dans une position intermédiaire.Thus, whatever the opening position of the opening, the wind-shutters are also in an extended position. The efficiency of the evacuation of fumes or aeration of the interior of the building can then be reduced when the opening is in an intermediate position.

L'invention a pour but de proposer un exutoire de désenfumage qui permet de réduire l'effet de surpression créé par l'ouvrant et qui autorise une fermeture ultérieure de l'exutoire de désenfumage.The invention aims to provide a smoke evacuation outlet that reduces the effect of overpressure created by the opening and allows a subsequent closure of the smoke evacuation outlet.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the following description, identical, similar or similar elements will be designated by the same reference numerals.

On a représenté aux figures un exutoire de désenfumage 10 qui est agencé sur le toit 12 d'un bâtiment (non représenté). Afin de simplifier la description qui va suivre, le toit 12 est ici horizontal. Cependant, il sera compris que l'invention s'applique également à un exutoire de désenfumage 10 agencé dans un toit 12 incliné.There is shown in the figures a smoke evacuation outlet 10 which is arranged on the roof 12 of a building (not shown). To simplify the description that follows, the roof 12 is here horizontal. However, it will be understood that the invention also applies to a smoke evacuation outlet 10 arranged in an inclined roof 12.

L'exutoire de désenfumage 10 comporte une costière 14 globalement cylindrique d'axe principal globalement vertical, et qui est ici de section horizontale rectangulaire. La costière 14 est agencée dans un logement complémentaire 16 du toit 12, et elle s'étend verticalement vers le haut depuis la face supérieure 12s du toit 12.The smoke evacuation outlet 10 comprises a generally cylindrical curb 14 of generally vertical main axis, and which is here of rectangular horizontal section. The curb 14 is arranged in a complementary housing 16 of the roof 12, and it extends vertically upwards from the upper face 12s of the roof 12.

La costière 14 délimite ainsi un canal d'évacuation 18 qui relie l'intérieur du bâtiment avec l'extérieur, permettant ainsi aux fumées de sortir du bâtiment, à la manière d'une cheminée.The curb 14 defines an evacuation channel 18 which connects the interior of the building with the outside, thus allowing fumes to exit the building, in the manner of a chimney.

On a représenté aux figures 1 à 4 un exutoire de désenfumage 10 qui comporte deux ouvrants mobiles opposés avant et arrière 20, dont chacun est mobile entre une position d'ouverture du canal d'évacuation 18 et une position d'obturation du canal d'évacuation 18 (non représentée) dans laquelle les ouvrants 20 s'étendent globalement horizontalement en recouvrant entièrement la costière 14 en s'appuyant sur les bords d'extrémité supérieure 14t, 14ℓ de la costière 14.FIGS. 1 to 4 show a smoke evacuation outlet 10 which comprises two opposed opposite front and rear mobile openings 20, each of which is movable between an open position of the evacuation channel 18 and a closed position of the evacuation channel 18 (not shown) in which the openings 20 extend generally horizontally by completely covering the curb 14 by resting on the upper end edges 14t, 14ℓ of the curb 14.

Les ouvrants 20 sont agencés sur la costière 14 de sorte que l'exutoire de désenfumage 10 présente une symétrie générale de conception par rapport à un plan vertical transversal médian.The openings 20 are arranged on the curb 14 so that the smoke evacuation outlet 10 has a general design symmetry with respect to a median transverse vertical plane.

L'exutoire de désenfumage peut aussi ne comporter qu'un seul panneau formant ouvrant 20 qui est apte à recouvrir entièrement la costière 14 lorsqu'il est en position de fermeture du canal d'évacuation 18, comme on l'a représenté aux figures 5 et 6.The smoke evacuation outlet may also comprise only one opening panel 20 which is able to completely cover the curb 14 when it is in the closed position of the discharge channel 18, as shown in FIGS. and 6.

Le choix du nombre d'ouvrants 20 est déterminé en fonction des dimensions de la costière 14, notamment en fonction de sa longueur "L", afin de limiter la masse de chaque ouvrant 20 et pour limiter de ce fait les dimensions des moyens d'entraînement ou de mise en mouvement de chaque ouvrant 20.The choice of the number of openings 20 is determined according to the dimensions of the curb 14, in particular according to its length "L", in order to limit the mass of each opening 20 and to thereby limit the dimensions of the means of driving or setting in motion each opening 20.

Ainsi, pour des grandes dimensions de la costière 14, l'exutoire de désenfumage 10 comporte deux ouvrants 20, et pour des dimensions plus réduites de la costière 14, l'exutoire de désenfumage 10 ne comporte qu'un ouvrant 20.Thus, for large dimensions of the curb 14, the smoke evacuation outlet 10 comprises two openings 20, and for smaller dimensions of the curb 14, the smoke evacuation outlet 10 has only one opening 20.

Dans la description de l'exutoire de désenfumage 10 qui va suivre, on fera référence à un seul ouvrant 20. Il sera compris que cette description s'applique aussi bien à un exutoire de désenfumage 10 qui comporte un seul ouvrant 20 qu'à un exutoire de désenfumage 10 qui comporte deux ouvrants 20, la description du second ouvrant 20 se déduisant de celle du premier ouvrant 20 par symétrie par rapport au plan général de symétrie.In the description of the smoke evacuation outlet 10 which will follow, reference will be made to a single opening 20. It will be understood that this description applies equally to a smoke evacuation outlet 10 which comprises a single opening 20 to a Smoke evacuation outlet 10 which has two openings 20, the description of the second opening 20 deduced from that of the first opening 20 by symmetry with respect to the general plane of symmetry.

L'ouvrant 20 est ici un panneau plan qui peut être réalisé en un matériau opaque ou en un matériau transparent ou translucide, permettant alors de réaliser un éclairage naturel du bâtiment. Selon une variante non représentée, l'ouvrant 20 est bombé pour empêcher toute accumulation d'eau ou de détritus sur sa face supérieure lorsqu'il est en positon de fermeture du canal d'évacuation 18.The opening 20 is here a flat panel that can be made of an opaque material or a transparent or translucent material, allowing then to achieve a natural lighting of the building. According to a variant not shown, the opening 20 is curved to prevent any accumulation of water or detritus on its upper face when it is in position of closure of the discharge channel 18.

Puisque la costière 14 est de section rectangulaire l'ouvrant 20 est globalement rectangulaire dont les grands côtés sont ici d'orientation générale transversale, et son bord transversal arrière 20b est monté articulé par rapport à la costière 14 autour d'un axe transversal A agencé à proximité d'un bord supérieur transversal 14t de la costière 14.Since the curb 14 is of rectangular section the opening 20 is generally rectangular whose long sides are here of transverse general orientation, and its rear transverse edge 20b is articulated relative to the curb 14 about a transverse axis arranged A near a transverse upper edge 14t of the curb 14.

Il peut être prévu d'autres moyens d'articulation et de mise en mouvement de l'ouvrant 20, comme par exemple un système de parallélogramme déformable (non représenté).It may be provided other means of articulation and movement of the opening 20, such as a deformable parallelogram system (not shown).

Les dimensions de l'ouvrant 20 sont au moins égales à celles du canal d'évacuation 18. Cependant, pour que la fermeture du canal d'évacuation 18 soit étanche, les dimensions de l'ouvrant 20 sont supérieure à celles du canal d'évacuation 18 et à celles de la costière 14.The dimensions of the opening 20 are at least equal to those of the discharge channel 18. However, for the closure of the discharge channel 18 is sealed, the dimensions of the opening 20 are greater than those of the channel of evacuation 18 and those of the curb 14.

De plus, le bord supérieur 14t, 14ℓ de la costière 14 est prolongé horizontalement vers l'extérieur par une collerette périphérique 21 sur laquelle l'ouvrant 20 s'appuie pour assurer une fermeture étanche du canal d'évacuation 18.In addition, the upper edge 14t, 14ℓ of the curb 14 is extended horizontally outwards by a peripheral collar 21 on which the opening 20 rests to ensure a tight closure of the discharge channel 18.

Lorsque l'ouvrant 20 occupe sa position d'ouverture du canal d'évacuation 18, il ne doit pas gêner l'évacuation des fumées en réduisant la section du canal d'évacuation. Pour cela, l'ouvrant 20 et la collerette 21 délimitent un angle "α" qui est de préférence supérieur ou égal à 90°.When the opening 20 is in its open position of the discharge channel 18, it must not interfere with the evacuation of fumes by reducing the section of the evacuation channel. For this, the opening 20 and the collar 21 define an angle "α" which is preferably greater than or equal to 90 °.

En plus de ses positions d'obturation et d'ouverture du canal d'évacuation 18, l'ouvrant 20 est apte à occuper plusieurs positions intermédiaires dites d'aération dans lesquelles l'angle "α" est inférieur à 90°, de sorte qu'un courant d'air se forme depuis l'intérieur du bâtiment vers l'extérieur.In addition to its closing and opening positions of the evacuation channel 18, the opening 20 is able to occupy several intermediate ventilation positions in which the angle "α" is less than 90 °, so a draft of air is formed from the inside of the building to the outside.

De manière connue, l'ouvrant 20 est mis en mouvement de sa position d'obturation vers la position d'ouverture par l'intermédiaire d'un vérin 22 dont une première extrémité 22a est reliée à la costière, et dont une deuxième extrémité 22b est reliée à l'ouvrant 20. Le vérin est ici du type oléopneumatique, pneumatique ou électrique et il agit sur l'ouvrant 20.In known manner, the opening 20 is moved from its closed position to the open position by means of a jack 22, a first end 22a is connected to the curb, and a second end 22b is connected 20. The cylinder is here of the oleopneumatic, pneumatic or electric type and it acts on the opening 20.

L'exutoire de désenfumage 10 comporte aussi des moyens (non représentés) qui permettent la commande de l'ouverture de l'ouvrant 20. D'une manière générale, ces moyens de commande consistent en un treuil qui comporte un câble dont une extrémité est reliée à l'ouvrant et dont l'autre extrémité s'enroule autour d'un tambour.The smoke evacuation outlet 10 also comprises means (not shown) which enable the opening of the opening 20 to be controlled. In general, these control means consist of a winch which comprises a cable of which one end is connected to the opening and whose other end wraps around a drum.

Lorsque le vérin 22 est un vérin pneumatique ou électrique, ce peut être un vérin à simple ou à double effet qui est commandé par des moyens rassemblés de façon connue dans une armoire de commande. De plus, l'énergie nécessaire à l'ouverture de l'ouvrant 20 provient d'une cartouche de gaz lorsqu'il s'agit d'un vérin pneumatique, ou bien d'une source électrique à basse tension fournissant une tension comprise entre 24 et 48 volts lorsque le vérin est du type électrique.When the cylinder 22 is a pneumatic or electric cylinder, it can be a single or double-acting cylinder which is controlled by means assembled in a known manner in a control cabinet. In addition, the energy required to open the opening 20 comes from a gas cartridge when it is a pneumatic cylinder, or a low voltage electrical source providing a voltage between 24 and 48 volts when the cylinder is of the electric type.

Le tambour peut être actionné automatiquement afin que le câble puisse se dérouler lorsque l'alarme incendie est déclenchée, sans l'intervention d'une personne. Il peut aussi être actionné manuellement, ce qui permet à l'utilisateur de commander manuellement l'ouverture de l'ouvrant 20 de sorte à n'ouvrir le canal d'évacuation 18 que partiellement dans le cas où l'exutoire de désenfumage 10 est utilisé pour l'aération du bâtiment. Ces moyens de commande peuvent également être réalisés par un réseau d'air ou de gaz sous pression, ainsi que par une alimentation électrique.The drum can be operated automatically so that the cable can take place when the fire alarm is triggered, without the intervention of a person. It can also be operated manually, which allows the user to manually control the opening of the opening 20 so as to open the discharge channel 18 only partially in the case where the smoke evacuation outlet 10 is used for ventilation of the building. These control means can also be achieved by a network of air or gas under pressure, as well as by a power supply.

L'exutoire de désenfumage 10 comporte aussi des volets 24 dits "pare-vent" qui permettent, lorsque l'ouvrant est en position d'ouverture, de délimiter partiellement le canal d'évacuation et de le prolonger vers le haut, afin d'améliorer la capacité d'évacuation des fumées de l'exutoire de désenfumage 10 en cas de vent.The smoke evacuation outlet 10 also includes shutters 24 called "windbreaks" which allow, when the opening is in the open position, to partially delimit the discharge channel and extend it upwards, in order to improve the smoke evacuation capacity of the smoke evacuation outlet 10 in case of wind.

Pour cela, les volets 24 s'étendent verticalement vers le haut au-delà du bord supérieur 14t, 14ℓ de la costière 14, ils forment alors un obstacle au vent pour l'empêcher de s'engouffrer dans le bâtiment en passant par l'exutoire de désenfumage 10.For this, the flaps 24 extend vertically upward beyond the upper edge 14t, 14ℓ of the curb 14, they then form an obstacle to the wind to prevent it from rushing into the building through the smoke evacuation outlet 10.

Conformément à l'invention, les volets 24 sont montés mobiles par rapport à la costière 14 entre une position escamotée (non représentée) dans laquelle ils ne prolongent pas le canal d'évacuation 18, et une position déployée représentée aux figures dans laquelle ils prolongent le canal d'évacuation 18.According to the invention, the flaps 24 are mounted movable relative to the curb 14 between a retracted position (not shown) in which they do not extend the discharge channel 18, and an extended position shown in the figures in which they extend the evacuation canal 18.

Les volets 24 sont aptes à occuper leur position escamotée lorsque l'ouvrant 20 est dans sa position d'obturation du canal d'évacuation 18. Dans leur position escamotée, les volets 24 sont dissimulés à l'intérieur de la costière 14 et/ou du bâtiment, et ils ne dépassent donc pas du bord supérieur 14ℓ de la costière 14. Les volets 24 ne forment alors plus un obstacle extérieur au vent ou aux intempéries, qui pourraient les endommager avec le temps, et les détritus ne peuvent alors pas s'accumuler sur l'ouvrant 20.The flaps 24 are able to occupy their retracted position when the opening 20 is in its closed position of the discharge channel 18. In their retracted position, the flaps 24 are concealed inside the curb 14 and / or of the building, and they do not exceed the upper edge 14ℓ of the curb 14. The flaps 24 then no longer form an external obstacle to wind or weather, which could damage over time, and the debris can not then s accumulate on the opening 20.

Les volets 24 sont aptes à occuper leur position déployée lorsque l'ouvrant 20 est au moins dans sa position d'ouverture du canal d'évacuation 18 pour que l'évacuation des fumées soit la plus efficace possible.The flaps 24 are able to occupy their deployed position when the opening 20 is at least in its open position of the discharge channel 18 so that the evacuation of fumes is as effective as possible.

Cependant, lorsque l'ouvrant 20 est dans une position intermédiaire, il peut être prévu que les volets 24 soient dans leur position escamotée ou dans leur position déployée.However, when the opening 20 is in an intermediate position, it can be provided that the flaps 24 are in their retracted position or in their deployed position.

A cet effet, il est prévu des moyens de commande du déploiement des volets 24 et des moyens de mise en mouvement des volets 24 (non représentés) qui permettent, en fonction du mode de réalisation de l'invention, que les volets 24 restent escamotés pour certaines positions d'ouverture de l'ouvrant 20 et que les volets soient déployés pour les autres positions d'ouverture de l'ouvrant 20.For this purpose, means are provided for controlling the deployment of flaps 24 and means for moving flaps 24 (not shown) which, depending on the embodiment of the invention, allow flaps 24 to remain retracted. for certain opening positions of the opening 20 and that the flaps are deployed for the other opening positions of the opening 20.

Les moyens de commande du déploiement des volets 24 sont indépendants des moyens de commande de l'ouverture de l'ouvrant 20, de sorte que les volets 24 se déploient par exemple en fonction de la vitesse ou de la direction du vent, ou bien à partir d'une certaine température à l'intérieur du bâtiment.The control means of the deployment of the flaps 24 are independent of the control means of the opening of the opening 20, so that the flaps 24 are deployed for example depending on the wind speed or direction, or from a certain temperature inside the building.

Aussi, selon une variante non représentée, les volets 24 peuvent être mis en mouvement par l'ouvrant par l'intermédiaire d'une tringlerie, cette tringlerie permettant par ailleurs, en fonction de sa configuration, de différer le déploiement des volets 24 par rapport à l'ouverture de l'ouvrant 20.Also, according to a variant not shown, the flaps 24 can be set in motion by the opening through a linkage, this linkage also allowing, depending on its configuration, to delay the deployment of the flaps 24 relative at the opening of the opening 20.

Les moyens de mise en mouvement des volets 24 peuvent aussi être distincts des moyens de mise en mouvement de l'ouvrant 20.The means for moving the flaps 24 can also be distinct from the means for moving the opening 20.

Ces moyens de mise en mouvement de volets 24 peuvent consister en des moyens élastiques, par exemple des ressorts, qui sont aptes à se détendre pour provoquer le déploiement des volets 24.These means for moving flaps 24 may consist of elastic means, for example springs, which are able to relax to cause the deployment of flaps 24.

Les volets 24 sont maintenus en position escamotée par les moyens de commande du déploiement des volets 24 qui sont indépendant des moyens de commande de l'ouverture de l'ouvrant 20.The flaps 24 are held in the retracted position by the control means of the deployment of the flaps 24 which are independent of the control means of the opening of the opening 20.

Enfin, le déploiement des volets 24 et l'ouverture de l'ouvrant 20 peuvent s'effectuer selon une séquence prédéfinie de sorte qu'ils s'effectuent en même temps ou bien à des instants différents.Finally, the deployment of the flaps 24 and the opening of the opening 20 can be performed in a predefined sequence so that they are performed at the same time or at different times.

D'une manière générale, la costière 14 est de section horizontale rectangulaire ou carrée, l'axe d'articulation A de l'ouvrant 20 est agencé le long d'une des parois de la costière 14, qui est ici la paroi transversale arrière 26b et l'ouvrant s'étend transversalement sur au moins toute la longueur de la paroi arrière 26b.In general, the curb 14 is of rectangular or square horizontal section, the hinge axis A of the opening 20 is arranged along one of the walls of the curb 14, which here is the rear transverse wall 26b and the opening extends transversely over at least the entire length of the rear wall 26b.

Ainsi, lorsqu'il est en position d'ouverture du canal d'évacuation 18, l'ouvrant 20 réalise la fonction pare-vent sur toute la longueur de ce côté 26b. Il est donc inutile d'agencer des volets 24 au niveau de la paroi arrière 26b.Thus, when it is in the open position of the discharge channel 18, the opening 20 performs the wind-barrier function along the entire length of this side 26b. It is therefore unnecessary to arrange flaps 24 at the rear wall 26b.

Les volets 24 doivent donc être agencés au niveau des autres parois, c'est à dire les parois latérales longitudinales 28 et, lorsque l'exutoire de désenfumage 10 ne comporte qu'un ouvrant 20, au niveau de la paroi transversale avant 26a. De plus, les volets 24 doivent s'étendre parallèlement à la paroi 26a, 28 associée pour que leur fonction pare-vent soit la plus efficace.The flaps 24 must therefore be arranged at the level of the other walls, that is to say the longitudinal side walls 28 and, when the smoke evacuation outlet 10 has only one opening 20, at the front transverse wall 26a. In addition, the flaps 24 must extend parallel to the wall 26a, 28 associated so that their wind barrier function is most effective.

Pour que la fonction pare-vent des volets 24 soit efficace, il faut aussi que le moins de vent possible circule entre le bord supérieur 14ℓ de la costière 14 et les volets 24. Pour cela, lorsque les volets 24 sont en position déployée, chacun est délimité par un bord inférieur 24i qui est horizontal et qui s'étend à proximité du bord supérieur 14ℓ de la costière 14.In order for the flap 24 to be effective, it is also necessary that as little wind as possible circulates between the upper edge 14ℓ of the curb 14 and the flaps 24. For this, when the flaps 24 are in the deployed position, each is delimited by a lower edge 24i which is horizontal and which extends close to the upper edge 14ℓ of the curb 14.

L'efficacité de l'exutoire de désenfumage 10 doit être la même, que le vent provienne de la droite ou bien de la gauche. Pour cela, l'exutoire de désenfumage 10 présente une symétrie par rapport à un plan longitudinal médian, c'est-à-dire que les volets 24 agencés au niveau d'une paroi latérale 28 sont identiques aux volets 24 agencés au niveau de l'autre paroi latérale 28.The efficiency of the smoke evacuation outlet 10 must be the same whether the wind comes from the right or from the left. For this, the smoke evacuation outlet 10 has a symmetry with respect to a median longitudinal plane, that is to say that the flaps 24 arranged at a side wall 28 are identical to the flaps 24 arranged at the level of the other side wall 28.

Selon un premier mode de réalisation de l'invention représenté aux figures 1 et 2, les volets 24 sont des panneaux rigides.According to a first embodiment of the invention shown in Figures 1 and 2, the flaps 24 are rigid panels.

L'exutoire de désenfumage 10 comporte ici deux types de volets 24.The smoke evacuation outlet 10 here comprises two types of flaps 24.

L'exutoire de désenfumage 10 comporte des premiers volets 24 qui sont reliés à la costière 14 de matière à pouvoir s'escamoter lorsque l'ouvrant 20 est en position d'obturation du canal d'évacuation 14.The smoke evacuation outlet 10 comprises first flaps 24 which are connected to the curb 14 of material to be retracted when the opening 20 is in the closed position of the evacuation channel 14.

Pour cela, chaque volet 24 est monté articulé par rapport à la costière 14 autour d'un axe horizontal perpendiculaire au plan du volet 24, c'est-à-dire autour d'un axe transversal lorsque le volet 24 est associé à une paroi latérale 28 et autour d'un axe longitudinal lorsque le volet 24 est associé à la paroi avant 26a.For this, each flap 24 is articulated with respect to the curb 14 about a horizontal axis perpendicular to the plane of the flap 24, that is to say around a transverse axis when the flap 24 is associated with a wall 28 and about a longitudinal axis when the flap 24 is associated with the front wall 26a.

De plus, cet axe d'articulation est agencé à proximité d'une extrémité du bord inférieur 24i du volet 24 pour que lorsque le volet 24 est en position escamotée, il s'étend verticalement en vis-à-vis de la face interne 28i de la paroi latérale 28 de la costière 14 associée, et au-dessous du bord supérieur 14ℓ de la costière 14.In addition, this hinge pin is arranged near an end of the lower edge 24i of the flap 24 so that when the flap 24 is in the retracted position, it extends vertically inwards. vis-à-vis the inner face 28i of the side wall 28 of the associated curb 14, and below the upper edge 14ℓ of the curb 14.

Selon une variante de réalisation de l'invention, le volet 24 est articulé par rapport à la costière autour d'un axe horizontal parallèle au bord inférieur 24i du volet 24, c'est-à-dire autour d'un axe longitudinal lorsque le volet 24 est associé à une paroi latérale 28, et autour d'un axe transversal lorsque le volet 24 est associé à la paroi avant 26a.According to an alternative embodiment of the invention, the flap 24 is articulated with respect to the curb about a horizontal axis parallel to the lower edge 24i of the flap 24, that is to say about a longitudinal axis when the flap 24 is associated with a side wall 28, and around a transverse axis when the flap 24 is associated with the front wall 26a.

Ainsi, lorsque le volet 24 est en position escamotée, il s'étend globalement horizontalement vers l'intérieur depuis le bord supérieur 14t, 14ℓ de la costière 14.Thus, when the flap 24 is in the retracted position, it extends generally horizontally inwards from the upper edge 14t, 14ℓ of the curb 14.

Selon une autre variante de réalisation de l'exutoire de désenfumage 10, le volet 24 est monté coulissant par rapport à la costière 14 parallèlement à la direction verticale. Ainsi, lorsque le volet 24 est en position escamotée, il s'étend verticalement en vis-à-vis de la face interne 28i de la paroi latérale 28 de la costière 14 associée, et au-dessous du bord supérieur 14ℓ de la costière 14, et lorsqu'il se déploie, il se déplace verticalement vers le haut.According to another embodiment of the smoke evacuation outlet 10, the flap 24 is slidably mounted relative to the curb 14 parallel to the vertical direction. Thus, when the flap 24 is in the retracted position, it extends vertically vis-à-vis the inner face 28i of the side wall 28 of the associated curb 14, and below the upper edge 14ℓ of the curb 14 and as it unfolds, it moves vertically upward.

Selon un autre mode de réalisation de l'invention représenté aux figures 3 et 4, les volets 24 sont réalisés en un matériau souple qui est apte à été replié sur lui-même lorsqu'il est en position escamotée et qui est apte à se déplier lorsqu'il se déploie.According to another embodiment of the invention shown in Figures 3 and 4, the flaps 24 are made of a flexible material which is adapted to be folded on itself when in the retracted position and is able to unfold. when it unfolds.

Chaque volet 24 a alors la forme d'un secteur angulaire de rayon égal à la longueur de l'ouvrant 20 et d'ouverture égale à l'angle "α" délimité par la costière 14 et l'ouvrant 20. Un côté du volet est alors le bord inférieur 24i, et l'autre côté du volet 24 est relié à l'ouvrant 20. De ce fait, lorsque l'ouvrant 20 se déplace vers sa position d'ouverture du canal d'évacuation 18, il entraîne par la même occasion le volet 24 vers sa position déployée.Each flap 24 then has the shape of an angular sector of radius equal to the length of the opening 20 and opening equal to the angle "α" delimited by the curb 14 and the opening 20. One side of the flap is then the lower edge 24i, and the other side of the flap 24 is connected to the opening 20. As a result, when the opening 20 moves to its open position of the discharge channel 18, it leads by the same occasion the flap 24 to its deployed position.

Quel que soit le mode de déploiement des volets 24, leurs dimensions et leurs formes sont limitées par les dimensions de l'exutoire de désenfumage 10 et par l'amplitude de leur mouvement.Whatever the mode of deployment of the flaps 24, their dimensions and shapes are limited by the dimensions of the smoke evacuation outlet 10 and the amplitude of their movement.

Ainsi, par exemple, lorsqu'un volet 24 est articulé autour d'un axe perpendiculaire au plan du volet 24, celui-ci des de forme globalement triangulaire dont un coté inférieur est le bord inférieur 24i, il est articulé au niveau de l'un de ses sommets dont un côté est le bord inférieur 24i et qui délimite un angle "β" égal à la course du volet 24.Thus, for example, when a flap 24 is hinged about an axis perpendicular to the plane of the flap 24, the latter of generally triangular shape of which a lower side is the lower edge 24i, it is articulated at the level of the one of its vertices whose one side is the lower edge 24i and which delimits an angle "β" equal to the stroke of the flap 24.

Aussi, lorsque le volet 24 est monté coulissant par rapport à la costière 14, il est de forme rectangulaire et de hauteur égale à la course du volet 24.Also, when the flap 24 is slidably mounted relative to the curb 14, it is of rectangular shape and of height equal to the stroke of the flap 24.

L'exutoire de désenfumage 10 comporte aussi des deuxièmes volets 24 qui sont fixes par rapport à l'ouvrant 20.The smoke evacuation outlet 10 also comprises second flaps 24 which are fixed with respect to the opening 20.

Ces volets 24 sont portés par les bords latéraux 30 de l'ouvrant 20 et ils s'étendent verticalement et longitudinalement globalement perpendiculairement au plan de l'ouvrant 20. Les volets 24 sont donc mobiles par rapport à la costière 14 autour de l'axe A d'articulation de l'ouvrant 20 par rapport à la costière 14.These flaps 24 are carried by the lateral edges 30 of the opening 20 and they extend vertically and longitudinally generally perpendicular to the plane of the opening 20. The flaps 24 are thus movable relative to the curb 14 about the axis A hinge of the opening 20 relative to the curb 14.

Ainsi, lorsque l'ouvrant 20 occupe sa position d'ouverture du canal d'évacuation 18, les volets 24 s'étendent au-delà du bord supérieur 14ℓ de la costière 14, et lorsque l'ouvrant 20 est dans sa position d'obturation du canal d'évacuation 18, les volets 24 sont dans leur position escamotée en s'étendant verticalement vers le bas depuis le bord supérieur 14ℓ de la costière 14.Thus, when the opening 20 occupies its open position of the discharge channel 18, the flaps 24 extend beyond the upper edge 14ℓ of the curb 14, and when the opening 20 is in its position d ' closing the discharge channel 18, the flaps 24 are in their retracted position extending vertically downwards from the upper edge 14ℓ of the curb 14.

Selon un premier mode de réalisation, les volets 24 sont fixés sur l'ouvrant 20 de sorte qu'en position escamotée ils sont agencés à l'intérieur de la costière 24. Selon un autre mode de réalisation, ils sont agencés de sorte à s'étendre à l'extérieur de la costière 14.According to a first embodiment, the flaps 24 are fixed on the opening 20 so that in the retracted position they are arranged inside the curb 24. According to another embodiment, they are arranged so as to extend to the outside of the curb 14.

Dans ce dernier mode de réalisation, les dimensions des volets 24 sont limitées par le fait qu'en position escamotée, l'extrémité libre 24a de chaque volet 24 vient en butée sur le toit 12 du bâtiment. A cet effet, la hauteur "h" des volets 24 doit être inférieur à la hauteur "H" de la costière 14.In this latter embodiment, the dimensions of the flaps 24 are limited by the fact that in the retracted position, the free end 24a of each flap 24 abuts on the roof 12 of the building. For this purpose, the height "h" of the flaps 24 must be less than the height "H" of the curb 14.

Lorsque l'exutoire de désenfumage 10 ne comporte qu'un seul ouvrant 20, comme représenté aux figures 5 et 6, il est nécessaire d'agencer au moins un volet 24 au niveau du bord supérieur de la paroi avant 26a.When the smoke evacuation outlet 10 has only one opening 20, as shown in Figures 5 and 6, it is necessary to arrange at least one flap 24 at the upper edge of the front wall 26a.

Ce volet 24 est de forme rectangulaire et son mode de déplacement peut être un de ceux décrits ci dessus.This flap 24 is rectangular in shape and its mode of displacement can be one of those described above.

L'exutoire de désenfumage 10 comporte aussi des moyens non représentés qui permettent le verrouillage de l'ouvrant 20 en position de fermeture. Ces moyens de verrouillage sont d'une manière générale agencés contre la face interne 27 de la paroi avant 26a de la costière 14, comme le volet 24.The smoke evacuation outlet 10 also comprises means not shown which allow the locking of the opening 20 in the closed position. These locking means are generally arranged against the inner face 27 of the front wall 26a of the curb 14, like the flap 24.

Pour que le volet 24 puisse se déployer sans contraintes, celui-ci est divisé en deux parties 32 qui sont disposées de part et d'autre des moyens de verrouillage.So that the flap 24 can be deployed without constraints, it is divided into two parts 32 which are arranged on either side of the locking means.

Selon un autre mode de réalisation de l'exutoire de désenfumage 10, l'ouvrant 20 est monté coulissant par rapport à la costière 14, parallèlement à une direction horizontale. L'ouvrant 20 est apte à coulisser vers l'arrière pur ouvrir le canal d'évacuation 18, et il est relié à la costière 14 par l'intermédiaire de glissières 34.According to another embodiment of the smoke evacuation outlet 10, the opening 20 is slidably mounted relative to the curb 14, parallel to a horizontal direction. The opening 20 is able to slide rearwardly to open the discharge channel 18, and it is connected to the curb 14 by means of slides 34.

Les glissières 34 sont des glissières télescopiques, ce qui permet qu'elles soient dissimulées entre l'ouvrant 20 et la costière 14 lorsque l'ouvrant 20 est en position de fermeture du canal d'évacuation 18, et elles permettent que l'ouvrant 20 puisse atteindre une position arrière extrême dans laquelle la totalité du canal d'évacuation 18 est ouverte.The slides 34 are telescopic slides, which allows them to be concealed between the opening 20 and the curb 14 when the opening 20 is in the closed position of the discharge channel 18, and they allow the opening 20 can reach an extreme rear position in which the entire discharge channel 18 is open.

Conformément à l'invention, l'exutoire de désenfumage 10 comporte des volets 24 qui peuvent avoir l'une quelconque des conceptions décrites ci-dessus l'exutoire de désenfumage 10 comporte ici deux volets 24 triangulaires agencés au niveau des parois latérales 28 de la costière 14, et un volet 24 rectangulaire agencé au niveau de la paroi avant 26a.According to the invention, the smoke evacuation outlet 10 comprises flaps 24 which may have any of the designs described above the smoke evacuation outlet 10 here comprises two triangular flaps 24 arranged at the side walls 28 of the curb 14, and a rectangular flap 24 arranged at the front wall 26a.

Cependant, les volets 24 qui sont agencés le long des parois latérales 28 peuvent être gênés par les glissières 34. De ce fait, les volets 24 ne s'étendent qu'à partir du milieu de la paroi latérale 28 associée jusque vers la paroi avant 26a. L'efficacité des volets est alors réduite, cependant, les glissières 34 ont elles-mêmes une certaine hauteur de sorte qu'elles ont aussi une action pare-vent.However, the flaps 24 which are arranged along the side walls 28 may be impeded by the slides 34. As a result, the flaps 24 extend only from the middle of the associated side wall 28 to the front wall 26a. The effectiveness of the flaps is then reduced, however, the slides 34 themselves have a certain height so that they also have a wind-barrier action.

Lorsque l'ouvrant 20 est en position d'ouverture, il s'étend horizontalement et il ne forme pas un obstacle au vent de sorte qu'il ne réalise pas la fonction pare-vent au niveau de la paroi arrière 26b.When the opening 20 is in the open position, it extends horizontally and does not form an obstacle to the wind so that it does not perform the wind barrier function at the rear wall 26b.

Pour que la fonction pare-vent soit réalisée au niveau de la paroi arrière 16b, l'ouvrant 20 porte un volet supplémentaire 36 qui s'étend verticalement vers le haut depuis son bord d'extrémité avant 38.For the wind barrier function to be performed at the rear wall 16b, the opening 20 carries an additional flap 36 which extends vertically upwards from its front end edge 38.

Ce volet supplémentaire 36 est ici fixe par rapport à l'ouvrant 20, cependant, il peut être mobile par rapport à l'ouvrant 20 de sorte qu'il se déploie pour assurer une fonction pare-vent lorsque cela est nécessaire.This additional flap 36 is here fixed relative to the opening 20, however, it can be movable relative to the opening 20 so that it deploys to provide a wind-resistant function when necessary.

Un exutoire de désenfumage 10 qui comporte des volets 24 conformes aux enseignements de l'invention voit son efficacité améliorée, tout en pouvant assurer d'autres fonctions telles que l'éclairement ou l'aération du bâtiment.A smoke evacuation outlet 10 which includes flaps 24 in accordance with the teachings of the invention is improved in its effectiveness, while being able to perform other functions such as illuminating or ventilating the building.

Par ailleurs, de tels volets 24 ont des formes conventionnelles qui sont adaptables à toutes les formes d'exutoires de désenfumage 10. Il est donc possible, pour un bâtiment qui possède un exutoire de désenfumage 10 conventionnel, d'ajouter des volets 24 conformes aux enseignements de l'invention pour améliorer l'efficacité du désenfumage.Moreover, such shutters 24 have conventional shapes that are adaptable to all forms of smoke evacuation outlet 10. It is therefore possible for a building that has a conventional smoke evacuation outlet 10 to add shutters 24 in accordance with teachings of the invention to improve the efficiency of smoke extraction.
