Abstract
Description
La présente invention concerne un dispositif de protection d'une façade d'un immeuble a plusieurs étages contre les flammes d'un incendie. The present invention relates to a device for protecting a facade of a multi-storey building against the flames of a fire.
L'un des problemes à résoudre pour la protection des immeubles contre les incendies est de retarder la propagation des flammes d'un étage a l'autre. One of the problems to be solved for the protection of buildings against fire is to delay the propagation of flames from one floor to another.
Cette propagation peut en effet se réaliser par les ouvertures ou baies dont les vitres ont été brisées sous lgeffet de la chaleur, les flammes venant alors lécher la façade extérieure et communiquer l'incendie aux étages supérieurs. This propagation can indeed take place through openings or openings whose windows have been broken under the effect of heat, the flames then licking the exterior facade and communicating the fire to the upper floors.
La présente invention vise a résoudre ce problème en proposant un dispositif de protection comportant des plaques déflectrices sensiblement horizontales, fixées extérieurement a la façade et entre chaque étage, de manière à augmenter le parcours horizontal des flammes a'échappant de la façade et à éloigner ces flammes de cette façade. The present invention aims to solve this problem by proposing a protection device comprising substantially horizontal deflecting plates, fixed externally to the facade and between each stage, so as to increase the horizontal path of the flames escaping from the facade and to distance these flames of this facade.
Les plaques déflectrices de l'invention sont avantageusement constituées par des tôles d'acier fixées par des consoles ponctuelles à la façade. The deflector plates of the invention are advantageously constituted by steel sheets fixed by point consoles to the facade.
Dans un mode de réalisation préféré de l'invention, les plaques déflectrices présentent chacune un rebord proximal dirigé vers le bas, un rebord distal dirigé vers le haut et une partie plane montant en pente douce depuis le rebord proximal jusqu'au rebord distal. In a preferred embodiment of the invention, the deflector plates each have a proximal edge directed downward, a distal edge directed upward and a flat part rising gently from the proximal edge to the distal edge.
Bien que le dispositif de la protection de l'invention puisse être appliqué à des immeubles de différents types de construction, il s'applique tout particulièrement aux immeubles à ossatures métalliques. Although the protection device of the invention can be applied to buildings of different types of construction, it is particularly applicable to buildings with metal frames.
Ainsi, dans le cas où la façade de l'immeuble comporte des poutres de rives nétalliques ayant une âme verticale, une aile horizontale inférieure et une aile horizontale supérieure, les consoles seront avantageusement formées chacune d'une tôle d'acier soudée à l'âme de la poutre de rive et à la plaque déflectrice.Thus, in the case where the facade of the building comprises beams of metallic shores having a vertical core, a lower horizontal wing and an upper horizontal wing, the consoles will advantageously be each formed from a steel sheet welded to the core of the edge beam and the deflector plate.
Etant donné que de tels immeubles à ossature métallique comportent fréquemment des poteaux métalliques extérieures le dispositif de protection de l'invention contribuera également à la stabilité de la poutre de rive et à celle des poteaux latéraux et de leurs attaches, en S 1opposantà la montée en température de ces éléments métalliques par l'eloi- gnement des flammes. Since such metal-framed buildings frequently have external metal posts, the protection device of the invention will also contribute to the stability of the edge beam and to that of the lateral posts and their attachments, by opposing the rise in temperature of these metallic elements by the distance of the flames.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description détaillée qui va suivre et qui se réfère auxdessinsannexés sur lesquels
La figure 1 est une vue en perspective d'une façade d'un immeuble munie d'un dispositif de protection selon l'invention ; et
la figure 2 est une vue en coupe verticale du dispositif représente à la figure 1.Other characteristics and advantages of the invention will be better understood on reading the detailed description which follows and which refers to the appended drawings on which
Figure 1 is a perspective view of a facade of a building provided with a protective device according to the invention; and
FIG. 2 is a view in vertical section of the device represented in FIG. 1.
On a représenté sur les figures 1 et 2 une partie d'une façade 10 d'un immeuble à plusieurs étages. Cette partie de façade comprend la poutre de rive 12 et la baie vitrée 14 d'un étage supérieur et la baie vitrée 16 d'un étage inférieur, les étages supérieur et inférieur précités étant séparés par un plancher 18. La poutre de rive 12 qui fait partie de la façade 10 présente une âme verticale 20, une aile horizontale inférieure 22 et une aile horizontale supérieure 24. La baie vitrée 14 de l'étage supérieur est raccordée à l'aile supérieure 24, tandis que la baie vitrée 16 de l'étage inférieur est raccordée à l'aile inférieure 22. FIGS. 1 and 2 show part of a facade 10 of a multi-storey building. This facade part comprises the edge beam 12 and the bay window 14 on an upper floor and the bay window 16 on a lower floor, the above and lower floors mentioned above being separated by a floor 18. The edge beam 12 which is part of the facade 10 has a vertical core 20, a lower horizontal wing 22 and an upper horizontal wing 24. The bay window 14 of the upper floor is connected to the upper wing 24, while the bay window 16 of the the lower stage is connected to the lower wing 22.
L'ossature du bâtiment considéré comporte également à l'extérieur de la façade, des poteaux verticaux 26, constitués par des poutres en I, qui contribuent au maintien de la façade. Ces poteaux scnt fixés aux poutres de rive 12 de chaque étage au moyen de goussets 28 qui sont d'une part boulonnés sur une aile d'un poteau 26 et d'autre part soudés sur l'âme de la poutre de rive 12. Par ailleurs, comme représenté sur la figure lt l'ossature du bâtiment comprend également, à l'extérieur de la façade, des potelets 30 servant à la fixation des garde-corps (non représentés). The framework of the building considered also includes outside the facade, vertical posts 26, constituted by I-beams, which contribute to the maintenance of the facade. These posts are fixed to the edge beams 12 of each stage by means of gussets 28 which are on the one hand bolted to a wing of a pole 26 and on the other hand welded to the core of the edge beam 12. By elsewhere, as shown in Figure lt the frame of the building also includes, outside the facade, posts 30 for fixing the railings (not shown).
Tous les éléments précités qui constituent la structure même de l'immeuble sont des éléments connus. All the aforementioned elements which constitute the very structure of the building are known elements.
Conformément à l'invention, on dispose à l'extérieur de la façade 10 des dispositifs de protection tels 32 destinés à retarder la propagation du feu d'un étage à l'autre par les baies telles 16 et 14. Ce dispositif de protection comporte une plaque déflectrice 34 sensiblement horizontale fixée extérieurement à la façade lO et entre chaque étage, par exemple au niveau du plancher 18 représenté sur la figure 2. In accordance with the invention, there are protective devices such as 32 outside the facade 10 intended to delay the propagation of fire from one floor to another by the bays such as 16 and 14. This protective device comprises a substantially horizontal deflector plate 34 fixed externally to the facade 10 and between each stage, for example at the level of the floor 18 shown in FIG. 2.
La plaque déflectrice 34 est constituée par une tôle d'acier fixée par des consoles ponctuelles 36 à la façade 10. La plaque déflectrice 34 présente un rebord proximal 38 dirigé vers le bas, un rebord distal 40 dirigé vers le haut et une partie plane 42 montant en pente douce depuis le rebord proximal 38 jusqu'au rebord distal 40. The deflector plate 34 is constituted by a steel sheet fixed by point consoles 36 to the facade 10. The deflector plate 34 has a proximal flange 38 directed downwards, a distal flange 40 directed upwards and a flat part 42 amount gently sloping from the proximal edge 38 to the distal edge 40.
Les consoles 36 sont formées chacune d'une tôle d'acier souaée ou boulonnez à l'âme 20 de la poutre denve 12 et soudée à la plaque déflectrice 34. The brackets 36 are each formed from a welded steel sheet or bolt to the core 20 of the denve beam 12 and welded to the deflector plate 34.
Comme on peut le constater sur la figure 2, le rebord proximal 38 de la plaque déflectrice 34 est espacé de l'aile inférieure 22 de la poutre de rive 20 et plus particulièrement du rebord 44 de l'aile 22. L'espace qui subsiste entre le rebord 38 et le rebord 44 est comblé par une plaque métallique de liaison 46 qui est soudée sur l'aile inférieure 22 et sur la partie plane 42 de la plaque déflectrice 34. As can be seen in Figure 2, the proximal flange 38 of the deflector plate 34 is spaced from the lower wing 22 of the edge beam 20 and more particularly from the flange 44 of the wing 22. The remaining space between the rim 38 and the rim 44 is filled by a metallic connecting plate 46 which is welded to the lower wing 22 and to the flat part 42 of the deflector plate 34.
La disposition de la plaque 46 permet de diminuer la transmission thermique entre la poutre de rive et la plaque déflectrice.The arrangement of the plate 46 makes it possible to reduce the thermal transmission between the edge beam and the deflector plate.
Les plaques déflectrices de l'invention seront disposées au-dessus des baies de chaque étage de manière à retarder la propagation du feu d'un étage à l'autre par les baies vitrées en augmentant le parcours horizontal des flammes. Ainsi, comme illustré sur la figure 2, les flammes provenant de la baie 16 suivront d'abord un parcours horizontal illustré sché- matiquement par la flèche F au lieu de monter verticalement le long de la façade en l'absence d'une plaque déflectrice. The deflector plates of the invention will be arranged above the bays of each stage so as to delay the propagation of the fire from one stage to the other by the bay windows by increasing the horizontal path of the flames. Thus, as illustrated in FIG. 2, the flames coming from bay 16 will first follow a horizontal course illustrated diagrammatically by arrow F instead of rising vertically along the facade in the absence of a deflector plate .
Dans le mode de réalisation particulier représenté sur les figures 1 et 2, le dispositif de l'invention devra être intercalé entre les poteaux 26. In the particular embodiment shown in FIGS. 1 and 2, the device of the invention must be inserted between the posts 26.
Bien que l'invention ait été décrite en référence particulière à un immeuble à ossature métallique, on comprendra que le dispositif peut être également appliqué à d'autres is eubles et en particulier à des immeubles de construction traditionnelle. Although the invention has been described with particular reference to a metal frame building, it will be understood that the device can also be applied to other buildings and in particular to buildings of traditional construction.
