Definitions

  • the invention relates to a fire barrier for pipe leadthroughs, in particular of plastic pipes on walls, in which, in the event of a fire, a closure element cuts through the pipe guided through the wall and closes the free pipe cross section in a fire-tight manner.

  • the known fire barrier is very expensive to manufacture due to its construction, and there is still the risk that the closure elements, which can be displaced per se, become attached to the housing of the fire barrier when they are not used for a long time. As this cannot be prevented by maintenance, it is possible that the fire barrier will not function properly in the event of a fire after a long installation period.
  • the object of the invention is to create a generic fire barrier, by means of which a pipe which is guided through a wall, in particular made of plastic, can be reliably separated and blocked in any fire situation.

In individual cases it is only necessary, for example, to check and, if necessary, replace the plastic screw 35, and to loosen the rod drive 15 by loosening screw connections from the joints 23, 24 and, if necessary, to replace them with a new rod drive 15. If, for example, deterioration in the performance of the compression spring due to aging is to be feared in the course of time, the functionality of the fire barrier 1 can thus always be fully maintained by appropriate maintenance intervals by exchanging the rod drive.

Abstract

Barrière coupe-feu pour traversées de tuyaux, en particulier de tuyaux en matière synthétique, dans laquelle en cas d'incendie un élément de fermeture coupe le tuyau (2) traversant la paroi et ferme la section ouverte du tuyau de manière étanche aux flammes. La barrière coupe-feu comporte un cadre (3) entourant le tuyau (2) et un clapet (4) en métal monté pivotant sur le cadre. Lors de l'apparition de la chaleur dégagée par l'incendie le clapet (4) vient s'appliquer contre le cadre (3) en basculant d'une position de repos dans un plan perpendiculaire à l'axe du tuyau en sectionnant ce tuyau. Afin de pouvoir monter la barrière coupe-feu (1) pour des tuyaux déjà installés dans des orifices (9) d'une paroi le cadre (3) est formé de deux parties. A cet effet, un profil en forme de U est donné au cadre, la partie ouverte pouvant être fermée par une plaque de fermeture (28). Sur les faces internes de la plaque de fermeture et du cadre (26) se trouvent des barrettes constituant une butée en forme de cadre contre laquelle le clapet (4) vient s'appliquer en cas d'incendie. Sur le pourtour du clapet (13) est disposée une nappe (10) de matière calorifuge qui est revêtue extérieurement d'une couche productrice d'une couche calorifuge.
