Abstract

The present invention relates to a metallic section for a fire-resistant door frame equipped with at least one thermal insulation zone. The purpose of the invention is to provide a metallic section easy to manufacture and having a zone which provides sufficient thermal insulation. The insulation zone of the metallic section according to the invention has a narrowing 20 of the material, extending in the longitudinal direction of the section 2.

Description

La présente invention concerne un profile métallique pour une huisserie pare-feu munie d'au moins une zone d'isolation thermique. The present invention relates to a metal profile for a fire-rated frame fitted with at least one thermal insulation zone.

On contrait, par le brevet belge 827106, une telle huisserie pare-feu munie d'une série de perforations pour obtenir une meilleure isolation thermique. One countered, by the Belgian patent 827106, such a fire-resistant frame fitted with a series of perforations to obtain better thermal insulation.

Le but de l'invention est de fournir un profilé métallieue facile à fabriquer et présentant une zone suffisamment thermoisolante. De préférence, un profilé métallique selon l'invention est rempli, après installation, d'un mortier pour qu une certaine quantité de chaleur puisse passer du profilé métallique au mortier durci. The object of the invention is to provide a metal profile which is easy to manufacture and which has a sufficiently heat-insulating zone. Preferably, a metal profile according to the invention is filled, after installation, with a mortar so that a certain amount of heat can pass from the metal profile to the hardened mortar.

L'opération de remplir d'un mortier le profilé métallique selon le brevet précité permet au mortier liquide de pénétrer dans la série de perforations de la zone d'isolation thermique.The operation of filling the metal profile according to the aforementioned patent with a mortar allows the liquid mortar to penetrate the series of perforations in the thermal insulation zone.

Il est à noter que l'on connait, par le brevet allemand 21 59 373, une entaille pratiquée dans Les parties recourbées d'un profilé. Ledit brevet ne fait pas mention de l'application, dans le cas d'un profilé, d'un rétrécissement de matériau pour freiner le passage de la chaleur. It should be noted that we know, from German patent 21 59 373, a notch made in the curved parts of a profile. Said patent does not mention the application, in the case of a profile, of a shrinking of material to slow the passage of heat.

D'autres caractéristiques de l'invention et celles qui ont été mentionnées seront indiquées dans les revendications et seront expLiquées, à l'aide d'un dessin, dans la description suivante. Other features of the invention and those which have been mentioned will be indicated in the claims and will be explained, with the aid of a drawing, in the following description.

Sur le dessin
- la figure 1 représente une vue en perspective d'une huisserie composée de profiles métalliques selon l'invention;
- la figure 2 représente une coupe à grande échelle selon la Lign II-II ue La figure 1; et
- La figure 3 représente le détail III à grande échelle de la figure 2.
On the drawing
- Figure 1 shows a perspective view of a frame made of metal profiles according to the invention;
- Figure 2 shows a large-scale section along the Lign II-II ue Figure 1; and
- Figure 3 shows the detail III on a large scale of Figure 2.

L'huisserie 1 de ta figure 1 est constituée de trois profilés 2 repre.entés sur la figure 2. Chaque profilé métallique 2 est essentiellement en forme de U et présente une rainure 3 susceptible de recevoir une porte 4 ou une fenêtre. L'huisserie 1 est, par exemple, encadrée par de La maçonnerie ou, selon la figure 2, montée dans une ouverture 5 ménagée dans un mur 6 et fixée au mur 6 par un nombre de bandes métalliques 7 et des vis 8 connues en soi, une chape réglable 9 étant fixée chaque fois par des vis 10 sur une telle bande 7. Les bords 12 d'ailes 11 du profilé métallique 2 s'engagent élastiquement avec encliquetage dans des supports 13 de La chape réglable 9.Les extrémités supérieure et inférieure de chaque profilé métallique 2 de chaque montant sont renforcées par un élément de pont 14 en forme de U, fixé aux ailes 11 par soudage par points. La rainure 3 est délimitée par un rebord en épingle à cheveux 15 et par une partie intermédiaire 16 qui est en position transversale par rapport à deux parties de corps 17 et 18. La partie intermédiaire 16 comprend une zone d'isolation thermique qui empêche le passage trop rapide de la chaleurs la partie 17 du corps à l'aile 11. Selon certaines normes de sécurité contre l'incendie, il est nécessaire d'éviter que la température en cas d'incendie du côté 19 de la porte 4 n'augmente de plus d'une certaine différence de température dans une demi-heure après le commencement de l'essai de réaction au feu. The frame 1 of your figure 1 consists of three sections 2 repre.entés on Figure 2. Each metal section 2 is essentially U-shaped and has a groove 3 capable of receiving a door 4 or a window. The frame 1 is, for example, framed by masonry or, according to Figure 2, mounted in an opening 5 formed in a wall 6 and fixed to the wall 6 by a number of metal strips 7 and screws 8 known per se , an adjustable yoke 9 being fixed each time by screws 10 on such a strip 7. The edges 12 of wings 11 of the metal profile 2 engage elastically with snap-fastening in supports 13 of the adjustable yoke 9.The upper ends and bottom of each metal section 2 of each upright are reinforced by a U-shaped bridge element 14, fixed to the wings 11 by spot welding. The groove 3 is delimited by a hairpin rim 15 and by an intermediate part 16 which is in transverse position with respect to two body parts 17 and 18. The intermediate part 16 comprises a zone of thermal insulation which prevents passage heat 17 is too fast for part 17 of the body to the wing 11. According to certain fire safety standards, it is necessary to prevent the temperature in the event of a fire on side 19 of door 4 from increasing more than a certain temperature difference within half an hour after the start of the reaction to fire test.

Il résulte d'essais de réaction au feu que la simple mesure consistant à pratiquer un rétrécissement 20 dans le matériau de la partie intermédiaire 16 aboutit largement au résultat requis. It follows from reaction to fire tests that the simple measure of practicing a shrinkage 20 in the material of the intermediate part 16 largely achieves the required result.

Le rétrécissement 20 s'étend en direction longitudinale du profilé 2 et est pratiqué au milieu de la partie intermédiaire 16 par une opération de roulement, le profilé étant déjà mis dans la forme requise par pliage d'une plaque métallique. La réalisation du rétrécissement 20 par roulement est un traitement continu du profilé pouvant s'effectuer à la chaîne, à un poste de roulement, le profilé 2 étant transporté en même temps d'un lieu de traitement à l'autre, avant ou après être coupé sur mesure. La rainure 3 comporte un joint d'étan chéité 21 connu en soi, empêchant le passage d'air chaud et de gaz fumigènes. L'espace 22 entre le profilé 2 et le mur 6 est rempli de mortier 23 incapable de s'échapper du profilé métallique 2 au niveau du rétrécissement. Par exemple, le profilé métallique 2 a une épaisseur de la tôle d de 1,5 mm, tandis que l'épaisseur locale s au niveau du rétrécissement 20, est de 0,7 mm par exemple, donc de l'ordre de 50% de l'épaisseur de la tôle d du profilé. Le rayon d'arrondi r du rétrécissement 20 est de 1 mm par exemple, tandis que L'angle de rétrécissement h est par exemple de 900 ou un peu moins. Il s'avère que le rétrécissement 20 ne réduit pas sensiblement la rigidité du profilé 2. The narrowing 20 extends in the longitudinal direction of the section 2 and is made in the middle of the intermediate part 16 by a rolling operation, the section being already put into the required shape by folding a metal plate. The realization of the shrinkage 20 by rolling is a continuous processing of the profile which can be carried out with the chain, at a rolling station, the profile 2 being transported at the same time from one place of treatment to another, before or after being cut to measure. The groove 3 comprises a seal 21 known in itself, preventing the passage of hot air and smoke gases. The space 22 between the profile 2 and the wall 6 is filled with mortar 23 incapable of escaping from the metal profile 2 at the level of the narrowing. For example, the metal profile 2 has a thickness of the sheet d of 1.5 mm, while the local thickness s at the level of the narrowing 20, is 0.7 mm for example, therefore of the order of 50% the thickness of the sheet metal d of the profile. The radius of rounding r of the narrowing 20 is 1 mm for example, while the angle of narrowing h is for example 900 or a little less. It turns out that the narrowing 20 does not significantly reduce the rigidity of the profile 2.
