Los elementos constructivos anti fuego pueden ser, por ejemplo, muros, tabiques, techos, puertas, compuertas, selladores, cubiertas... Some installations, such as certain buildings, or tunnels, must incorporate anti-fire building elements that prevent the spread of fire to certain areas. The fire-fighting building elements can be, for example, walls, partitions, ceilings, doors, gates, sealants, covers ...
Los elementos anti fuego deben ser capaces de soportar, sin degradarse, la acción de las llamas, durante al menos un período de tiempo previamente establecido, así como presentar unas características de transmisión de calor que garanticen que la temperatura en el lado opuesto al fuego no es superior a un valor preestablecido. The anti-fire elements must be able to withstand, without degrading, the action of the flames, for at least a previously established period of time, as well as have heat transmission characteristics that guarantee that the temperature on the side opposite to the fire does not It is greater than a preset value.
Para construir los elementos anti fuego se emplean materiales que son conocidos por su resistencia al fuego, como por ejemplo, placas de cartón yeso, o placas de silicato de calcio. Materials that are known for their fire resistance are used to construct the fire elements, such as plasterboard, or calcium silicate plates.
En este sentido, se caracteriza la resistencia al fuego de uno de dichos elementos anti fuego mediante una codificación denominada RF X, donde X es el número de minutos que el mencionado elemento anti fuego es capaz de soportar la acción de las llamas sin perder funcionalidad. In this sense, the fire resistance of one of said anti-fire elements is characterized by an encoding called RF X, where X is the number of minutes that said anti-fire element is able to withstand the action of the flames without losing functionality.
En el caso concreto de las puertas, por ejemplo, se conocen puertas de madera de la clase RF 60, así como puertas, al menos en parte metálicas, de la clase RF 180. In the specific case of doors, for example, wooden doors of class RF 60 are known, as well as doors, at least in part metal, of class RF 180.
La presente invención se refiere a un cerramiento cortafuegos que, debido a su configuración, responde a una clase de resistencia superior a los cerramientos conocidos en el estado de la técnica. The present invention relates to a firewall enclosure that, due to its configuration, responds to a class of resistance superior to the enclosures known in the state of the art.
