Junta intumescente para compuertas cortafuegos aplicables a conductos de ventilación y similares.Intumescent gasket for fire dampers applicable to ventilation ducts and the like.
La presente invención se refiere a una junta intumescente aplicable en los conductos de ventilación, aire acondicionado y similares, que se dispone en correspondencia con la compuerta cortafuegos que normalmente se coloca en este tipo de conductos para evitar la propagación del fuego en el caso de que se origine un incendio en el edificio correspondiente.The present invention relates to a joint Intumescent applicable in ventilation ducts, air conditioning and the like, which is available in correspondence with the Fire damper that is normally placed in this type of ducts to prevent the spread of fire in the event that originate a fire in the corresponding building.
El objeto de la invención es proporcionar una disposición apropiada y óptima de una junta intumescente, en correspondencia con la compuerta cortafuegos que es aplicable en el conducto de ventilación y similares, para conseguir un perfecto cierre hermético de la propia compuerta en caso de un incendio.The object of the invention is to provide a appropriate and optimal arrangement of an intumescent joint, in correspondence with the fire damper that is applicable in the ventilation duct and the like, to achieve a perfect airtight closure of the gate itself in case of a fire.
Las compuertas cortafuegos que se incorporan en los conductos de ventilación, aire acondicionado y similares, suelen estar constituidas en materiales ignífugos y resistentes al calor, al objeto de que dichas compuertas, que normalmente se encuentran en posición de apertura, se cierren por cualquier sistema convencional, cuando se origina un fuego, al objeto de evitar la propagación del fuego a través de los conductos correspondientes.The fire dampers that are incorporated in ventilation ducts, air conditioning and the like, they are usually made of flame retardant and resistant materials heat, so that these gates, which are normally are in the open position, close by any conventional system, when a fire originates, in order to prevent the spread of fire through the ducts corresponding.
No obstante, este tipo de puertas adolecen de un problema, consistente en que si bien cortan la propagación del fuego, no cierran herméticamente permitiendo el paso de humos e incluso la propagación del calor de un lado a otro.However, these types of doors suffer from a problem, that although they cut the spread of fire, do not close tightly allowing the passage of fumes and even the spread of heat from side to side.
En cualquier caso, se conocen juntas obturadoras intumescentes contra el fuego, como es la descrita en la patente europea 0404419, aunque en este caso la junta está definida por las características de su naturaleza, y no por su estructura ni aplicación.In any case, sealing joints are known intumescent against fire, as described in the patent European 0404419, although in this case the board is defined by the characteristics of its nature, and not because of its structure or application.
Sin embargo, en el modelo de utilidad español 1042326 se describe una puerta con marcos resistentes al fuego que incluye juntas intumescentes, aunque están previstas para su aplicación en puertas normales de cortafuegos y no para compuertas de conductos de ventilación, pudiéndose decir otro tanto en relación con el modelo de utilidad español 1050026, en donde se describe una puerta ignífuga que también incluye una junta entre el marco y el canto de la puerta, para evitar el paso de humos en caso de incendios.However, in the Spanish utility model 1042326 describes a door with fire resistant frames that includes intumescent boards, although they are planned for application in normal fire doors and not for gates of ventilation ducts, one can say the same in relation to with the Spanish utility model 1050026, which describes a fireproof door that also includes a gasket between the frame and the door edge, to prevent the passage of smoke in case of fires.
En definitiva, no se conocen documentos ni aplicaciones de juntas intumescentes en conductos de aire acondicionado, ventilación y similares, previstos para su utilización en compuertas cortafuegos que se montan en este tipo de conductos.In short, no documents or documents are known. Intumescent gasket applications in air ducts conditioning, ventilation and the like, planned for use in fire dampers that are mounted in this type of ducts
La junta intumescente que se preconiza, ha sido concebida para cubrir un vacío en cuanto a los sistemas previstos para evitar la propagación de fuego en conductos de ventilación, aire acondicionado y similares, estando además prevista para su aplicación tanto en conductos de contorno poligonal como en conductos de contorno circular, presentando la particularidad de que está constituida por una ancha banda que se fija, bien mediante pegado, remachado, grapado, etc, por el interior del conducto de que se trate, y en correspondencia con la posición de montaje de la correspondiente compuerta cortafuegos, todo ello de manera tal que cuando se produce un fuego y la compuerta ocupa su posición de cierre, la junta intumescente se expande y produce un cierre hermético con la puerta, evitando no solamente la propagación del fuego sino el paso de humos.The intumescent board that is recommended has been designed to cover a gap in terms of the planned systems to prevent the spread of fire in ventilation ducts, air conditioning and the like, also being planned for application both in polygonal contour conduits and in circular contour ducts, presenting the peculiarity that It consists of a broad band that is fixed, either by glued, riveted, stapled, etc., inside the duct concerned, and in correspondence with the mounting position of the corresponding fire damper, all in a way that when a fire occurs and the gate occupies its position of closure, the intumescent joint expands and produces a closure hermetic with the door, preventing not only the spread of the Fire but the passage of smoke.
Se ha previsto igualmente que el conducto, que es de naturaleza metálica normalmente, esté afectado en correspondencia en la zona de ubicación o posicionado de la junta, de unos orificios que reducen drásticamente el coeficiente de conductividad térmica del propio material metálico que constituye el conducto, ya que éste es buen conductor de calor y el aire, que determina el espacio vacío originado por los orificios, es mal conductor térmico, con lo que el calor pasará mayoritariamente por los espacios definidos entre los orificios, es decir, por las pequeñas zonas donde existe metal conductor térmico, lo que disminuye, como se decía, la conductividad térmica, reduciendo con ello la transmisión del calor.It is also foreseen that the duct, which is of a metallic nature normally, be affected in correspondence in the location or position zone of the board, of holes that drastically reduce the coefficient of thermal conductivity of the metallic material itself that constitutes the duct, since this is a good conductor of heat and air, which determine the empty space caused by the holes, it is wrong thermal conductor, so that heat will mostly pass through the spaces defined between the holes, that is, by the small areas where there is thermal conductive metal, which decreases, as said, thermal conductivity, reducing with It the heat transmission.
La junta intumescente puede ir fijada directamente en la parte interna del conducto, o bien ir montada y fijada convenientemente sobre la periferia o contorno de la compuerta, de manera que en cualquier caso la junta lo que va realizar con el calor es su dilatación y por lo tanto el cierre hermético entre conducto y compuerta.The intumescent joint can be fixed directly on the inside of the duct, or go mounted and conveniently fixed on the periphery or contour of the gate, so that in any case the board what goes perform with heat is its dilation and therefore the closure hermetic between duct and gate.
Evidentemente, la compuerta podrá ser también de cualquier naturaleza y material de los utilizados en el mercado, o bien está formada por un núcleo a base de capas de yeso, que queda envuelto por unas placas metálicas que impiden que las capas de yeso reciban directamente el fuego, evitando el erosionado y desmenuzado de ese núcleo de la compuerta cortafuegos, con la particularidad de que la junta intumescente, en el caso en el que esté aplicada sobre este tipo de puertas, irá fijada mediante remaches o cualquier otro sistema convencional a las citadas placas protectoras y externa de hierro con las que se complementa la compuerta cortafuegos.Obviously, the gate may also be any nature and material of those used in the market, or It is well formed by a core based on layers of plaster, which remains wrapped by metal plates that prevent layers of plaster directly receive the fire, avoiding eroding and shredded from that core of the fire damper, with the particularity of the intumescent board, in the case where be applied on this type of doors, it will be fixed by rivets or any other conventional system to said plates protective and external iron with which the fire damper.
Entre las ventajas más importantes que pueden citarse, derivadas de la junta intumescente y su aplicación, están las siguientes:Among the most important advantages that can cited, derived from the intumescent board and its application, are the following:
- --
- Permite un paso completamente diáfano a través del conducto en el que se aplique.It allows a completely diaphanous passage to through the conduit in which it is applied.
- --
- Se originan menores pérdidas de carga.Be cause lower load losses.
- --
- Las instalaciones pueden funcionar con menor gasto energético.The facilities can operate with lower energy expenditure.
- --
- En caso de incendio produce un cerramiento completamente hermético.In case of fire produces a completely enclosure airtight.
- --
- Los orificios realizados sobre el conducto, en correspondencia con la disposición de la junta intumescente, permiten no solamente reducir la conductividad térmica sino ver el estado de la junta intumescente.The holes made on the duct, in correspondence with the Intumescent board layout, not only reduce thermal conductivity but see the state of the board intumescent
