Description

       

  "Clapet coupe-feu" L'invention concerne un clapet coupe-feu destiné à être appliqué dans des gaines métalliques servant, d'une manière générale, à distribuer de l'air chaud et/ou conditionné dans

  
les constructions. Il est bien connu que ces gaines, qui traversent les murs de tous les locaux, forment un danger réel

  
en cas d'incendie, étant donné que le feu se répand, d'une manière brusque, via ces gaines, d'un local à l'autre.

  
Afin d'éviter un tel développement du feu, les susdites gaines sont pourvues, à chaque passage d'un mur ou d'un niveau coupe-feu, d'un clapet coupe-feu.

  
Toutefois, les clapets coupe-feu connus sont relativement compliqués et coûteux, ce qui augmente sensiblement le coût d'une installation de chauffage.

  
Les désavantages des clapets coupe-feu connus sont, entre autres, la formation de chaque unité par deux caissons boulonnés l'un à l'autre par l'intermédiaire d'un cadre en une matière d'isolation thermique, chaque caisson portant une partie des accessoires, tels que le clapet proprement dit et les moyens pour retenir ce clapet dans sa position ouverte.

  
Un autre désavantage est que ces clapets coupe-feu sont pourvus d'un clapet proprement dit à axe incorporé nécessitant des moyens, tels que ressorts, contre-poids ou similaires, sollicitant le clapet proprement dit vers sa position de fermeture en cas d'incendie.

  
Les clapets coupe-feu connus exigent, afin d'obtenir une fermeture efficace en cas d'incendie, différents butées fixées séparément dans les caissons ou en faisant partie.

  
Le clapet coupe-feu selon l'invention est, par rapport

  
aux clapets connus, d'une construction extrêmement simple, donc peu coûteuse, et il est monté d'une manière auto-fermante.

  
Ce clapet consiste substantiellement en un seul caisson en métal, pourvu, à chaque extrémité, d'une bride dont au moins l'une des deux est extérieurement pourvue d'une épaisseur d'un matériau isolant thermique et, suspendu à rotation libre dans

  
ce caisson, un clapet autofermant proprement dit en une matière d'isolation thermique.

  
Afin de mieux faire ressortir les susdites et d'autres caractéristiques et avantages du clapet selon l'invention, une exécution est décrite ci-après en se référant aux dessins annexés dans lesquels :
la figure 1 représente, en vue latérale, le clapet coupefeu selon l'invention; la figure 2 est une vue selon la flèche F2; la figure 3 est une vue en plan du clapet;

  
les figures 4 et 5 représentent, respectivement en position ouverte et en position fermée, une coupe verticale du clapet monté dans un mur.

  
Dans sa forme la plus simple, telle que représentée dans

  
les dessins, le clapet consiste en un seul caisson 1 en métal

  
 <EMI ID=1.1> 

  
lesquelles le caisson est solidarisé dans la gaine transportant l'air conditionné.

  
Afin d'éviter ou tout au moins de réduire au maximum la transmission de chaleur de l'une des extrémités du caisson 1 à

  
 <EMI ID=2.1> 

  
pourvue d'une épaisseur adéquate 4 en un matériau isolant thermique.

  
Le clapet 5 proprement dit est réalisé en une matière d'isolation thermique, de préférence, tout comme pour l'épaisseur 4, exempte d'amiante. L'épaisseur du clapet est fonction de la résistance au feu désirée. Dans cette exécution, ce clapet est formé par deux plaques collées, agrafées ou vissées l'une sur l'autre. Le clapet ainsi obtenu est pourvu, sur son contour, d'un joint coupe-feu ignifuge 6 pouvant coopérer avec les faces internes du caisson 1 afin d'obtenir, en cas d'incendie, une fermeture totale du caisson 1, respectivement de la gaine concernée.

  
Comme clairement illustré à la figure 5, le clapet 5 bute, dans sa position de fermeture, contre la traverse supérieure 7

  
de l'épaisseur 4 laquelle dépasse, à cette fin, la face intérieure de la paroi supérieure du caisson 1.

  
Une caractéristique très importante de l'invention se trouve dans le fait que l'axe de rotation 8 du clapet 5 est fixé à l'extérieur de ce clapet de manière à ce que le clapet peut basculer de lui-même vers la position de fermeture, s'il n'est pas retenu.

  
Afin de pouvoir commander et/ou retenir le clapet, l'axe 8

  
 <EMI ID=3.1> 

  
le clapet 5 manuellement mais, d'une manière générale, le clapet 5 sera retenu dans sa position ouverte par un fusible thermique. D'autres systèmes sont également possibles, par exemple un servomoteur pneumatique commandant l'axe 8 par l'intermédiaire ou non

  
 <EMI ID=4.1> 

  
des moyens électromagnétiques; etc.

  
De cette manière, on obtient un clapet coupe-feu extrêmement simple consistant en un seul caisson et à clapet à fermeture automatique sans nécessité d'un contre-poids, ressort ou similaire.

REVENDICATIONS.

  
1.- Clapet coupe-feu, caractérisé en ce qu'il consiste en un seul caisson en métal pourvu, à chaque extrémité, d'une bride dont au moins l'une des deux est extérieurement pourvue d'une épaisseur d'un matériau isolant thermique et, suspendu à rotation libre dans ce caisson, un clapet autofermant proprement dit en une matière d'isolation thermique.



  "Fire damper" The invention relates to a fire damper intended to be applied in metal ducts serving, in general, to distribute hot and / or conditioned air in

  
the constructions. It is well known that these sheaths, which pass through the walls of all the premises, constitute a real danger

  
in the event of a fire, since the fire suddenly spreads through these ducts from one room to another.

  
In order to avoid such development of the fire, the above sheaths are provided, at each passage of a wall or a fire level, with a fire damper.

  
However, known fire dampers are relatively complicated and expensive, which significantly increases the cost of a heating installation.

  
The disadvantages of known fire dampers are, inter alia, the formation of each unit by two boxes bolted to each other by means of a frame made of a thermal insulation material, each box carrying a part accessories, such as the valve itself and the means for retaining this valve in its open position.

  
Another disadvantage is that these fire dampers are provided with a damper proper with incorporated axis requiring means, such as springs, counterweight or the like, urging the damper proper towards its closed position in the event of fire. .

  
Known fire dampers require, in order to obtain an effective closure in the event of a fire, different stops fixed separately in the boxes or forming part of them.

  
The fire damper according to the invention is, relative

  
to known valves, of an extremely simple construction, therefore inexpensive, and it is mounted in a self-closing manner.

  
This valve consists essentially of a single metal box, provided, at each end, with a flange of which at least one of the two is externally provided with a thickness of a thermal insulating material and, suspended with free rotation in

  
this box, a self-closing valve proper in a thermal insulation material.

  
In order to better highlight the above and other characteristics and advantages of the valve according to the invention, an embodiment is described below with reference to the accompanying drawings in which:
Figure 1 shows, in side view, the fire valve according to the invention; Figure 2 is a view along arrow F2; Figure 3 is a plan view of the valve;

  
Figures 4 and 5 show, respectively in the open position and in the closed position, a vertical section of the valve mounted in a wall.

  
In its simplest form, as shown in

  
the drawings, the valve consists of a single metal box 1

  
 <EMI ID = 1.1>

  
which the box is secured in the sheath carrying the air conditioning.

  
In order to avoid or at least to minimize the transmission of heat from one end of the box 1 to

  
 <EMI ID = 2.1>

  
provided with an adequate thickness 4 of a thermal insulating material.

  
The valve 5 itself is made of a thermal insulation material, preferably, as for the thickness 4, free of asbestos. The thickness of the valve is a function of the desired fire resistance. In this embodiment, this valve is formed by two plates glued, stapled or screwed one on the other. The valve thus obtained is provided, on its contour, with a fire-retardant fire seal 6 which can cooperate with the internal faces of the box 1 in order to obtain, in the event of fire, a total closure of the box 1, sheath concerned.

  
As clearly illustrated in Figure 5, the valve 5 abuts, in its closed position, against the upper cross member 7

  
of thickness 4 which, for this purpose, exceeds the internal face of the upper wall of the box 1.

  
A very important characteristic of the invention lies in the fact that the axis of rotation 8 of the valve 5 is fixed to the outside of this valve so that the valve can tilt by itself towards the closed position. , if it is not selected.

  
In order to be able to control and / or hold the valve, axis 8

  
 <EMI ID = 3.1>

  
the valve 5 manually but, in general, the valve 5 will be retained in its open position by a thermal fuse. Other systems are also possible, for example a pneumatic servomotor controlling the axis 8 via or not

  
 <EMI ID = 4.1>

  
electromagnetic means; etc.

  
In this way, an extremely simple fire damper consisting of a single box and a self-closing damper without the need for a counterweight, spring or the like is obtained.
