Description

CLOISON VITREE COUPE-FEU WINDOW GLASS PARTITION
L'invention concerne les éléments d'huisseries résistants au feu.The invention relates to fire resistant door frames.
Le principe fondamental d'un élément coupe-feu ne repose pas tant sur son incombustibilité que sur ses capacités de résistance plus ou moins longue au franchissement de la chaleur des flammes et des fumées potentiellement toxiques et sa stabilité. Pour obtenir une bonne résistance au feu, l'agencement des éléments joue un rôle au moins aussi important que le choix des matériaux eux-mêmes : un simple détail de construction permet de rajouter de précieuses minutes au délai de franchissement des flammes.The fundamental principle of a fire-rated element is not based so much on its incombustibility as on its capacities of more or less long resistance to the crossing of the heat of flames and potentially toxic fumes and its stability. To obtain good fire resistance, the arrangement of the elements plays at least as important a role as the choice of the materials themselves: a simple construction detail allows precious minutes to be added to the delay in crossing the flames.
L'architecture moderne réserve une place sans cesse croissante aux cloisons métalliques, d'une esthétique sobre et faciles à entretenir. Or, l'usage de métal ne constitue pas la meilleure solution pour une cloison coupe-feu. Le métal étant bon conducteur, la température de la face opposée au feu peut atteindre rapidement des valeurs inacceptables (+ 150°C) , favorisant l'extension d'un sinistre. L'aluminium, non seulement est un des matériau les plus conducteur, mais ramollis en outre à la chaleur; perdant ainsi rapidement ses qualités mécaniques.Modern architecture reserves an ever-increasing place for metal partitions, with a sober aesthetic and easy to maintain. However, the use of metal is not the best solution for a firewall. As the metal is a good conductor, the temperature of the surface opposite the fire can quickly reach unacceptable values (+ 150 ° C), favoring the extension of a disaster. Aluminum is not only one of the most conductive materials, but also softened by heat; thus quickly losing its mechanical qualities.
DE-U-298 19 673 décrit ainsi une paroi coupe-feu dotée de cadres en bois où des profilés en aluminium sont accolés. En l'occurrence, ne jouant aucun rôle dans la résistance au feu, ces profilés métalliques abaissent la tenue au feu de l'ensemble de la paroi.DE-U-298 19 673 thus describes a fire wall with wooden frames where aluminum profiles are joined. In this case, playing no role in fire resistance, these metal profiles lower the fire resistance of the entire wall.
Le but de l'invention est la mise sur le marché de cloisons offrant une bonne résistance au feu et pouvant, de surcroît, être recouverte d'aluminium sans dégradation de sa tenue au feu. FR- 2 708 660 décrit une fenêtre à haute résistance au feu intégrée dans un mur classique. Le châssis de la fenêtre est muni d'un double joint foisonnant, qui ne tient cependant pas compte des possibilités de déformation du dormant.The object of the invention is the placing on the market of partitions offering good fire resistance and which can, moreover, be covered with aluminum without degrading its resistance to fire. FR- 2 708 660 describes a window with high fire resistance integrated into a conventional wall. The window frame is provided with an abundant double seal, which does not however take into account the possibilities of deformation of the frame.
Un but plus particulier de l'invention est que de tels éléments vitrés réussissent les tests normalisés de résistance au feu de 30 et 60 minutes, et même davantage.A more particular object of the invention is that such glazed elements pass the standardized fire resistance tests of 30 and 60 minutes, and even more.
L'invention a pour objet une cloison coupe-feu vitrée comprenant au moins un battant et un dormant, une face avant et une face arrière dans laquelle les éléments formant les ouvrants et le dormant sont réalisés en bois massif et/ou lamelle, leur face extérieure s ' étendant dans un plan, soit celui de la face avant, soit celui de la face arrière lorsque les ouvrants sont fermés; le cadre du dormant est muni d'une battée de frappe périphérique et les ouvrants d'une feuillure de frappe de dimensions complémentaires à celles de la battée de frappe, de sorte qu'un interstice en Z sépare chaque ouvrant de la partie du dormant correspondante; un joint foisonnant continu est encastré dans chacune des faces de l'interstice le long de chacune des branches du Z, près de la barre centrale du Z.The subject of the invention is a glazed fire partition comprising at least one leaf and one frame, a front face and a rear face in which the elements forming the opening and the frame are made of solid wood and / or slat, their face exterior extending in a plane, either that of the front face, or that of the rear face when the doors are closed; the frame of the frame is provided with a peripheral striking strip and the opening parts of a striking rabbet of dimensions complementary to those of the striking section, so that a Z-shaped gap separates each opening element from the corresponding frame part ; a continuous abundant joint is embedded in each of the faces of the gap along each of the branches of the Z, near the central bar of the Z.
Suivant un mode de réalisation avantageux, les vitres résistant au feu sont encastrée sensiblement dans le plan médian entre le plan de la face avant et celui de la face arrière, posées dans une battée périphérique intérieure sur des cales résistant aux hautes températures; la dite battée est fermée par une parclose périphérique ne dépassant pas du plan de la face correspondante; des bandes continues de mousse en fibres isolantes sont disposées de part et d'autre des vitres, respectivement en fond de battée et le long de la parclose; un joint de silicone neutre est injecté dans l'espace subsistant entre les vitres, les parcloses et les battées . Suivant un mode de réalisation avantageux, les faces avant et/ou arrières de la porte sont recouvertes par des profilés métalliques à section en U fixés sur des clips, les branches de ces profilés en U engagées dans les interstices en Z ayant une longueur inférieure à celles du Z.According to an advantageous embodiment, the fire-resistant panes are embedded substantially in the median plane between the plane of the front face and that of the rear face, placed in an inner peripheral opening on wedges resistant to high temperatures; said beat is closed by a peripheral glazing bead not exceeding the plane of the corresponding face; continuous strips of insulating fiber foam are arranged on either side of the panes, respectively at the bottom of the battée and along the glazing bead; a neutral silicone seal is injected into the remaining space between the windows, the glazing beads and the battées. According to an advantageous embodiment, the front and / or rear faces of the door are covered by metal profiles with U-shaped section fixed on clips, the branches of these U-shaped profiles engaged in the Z-shaped interstices having a length less than those of Z.
Chaque cadre en bois massif et/ou lamelle est, de préférence, assemblé par double tenon et enfourchement .Each solid wood frame and / or slat is preferably assembled by double tenon and fork.
Le dormant comprend avantageusement, du côté où il est en contact avec la maçonnerie, une feuillure apte à recevoir une latte périphérique fixée à la dite maçonnerie, une latte de finition munie d'une dent refermant la dite feuillure sur la dite latte périphérique, un joint foisonnant étant disposé entre la latte périphérique et le flanc de la feuillure.The frame advantageously comprises, on the side where it is in contact with the masonry, a rebate capable of receiving a peripheral batten fixed to said masonry, a finishing batten provided with a tooth closing said rebate on said peripheral batten abundant joint being disposed between the peripheral batten and the side of the rebate.
La latte périphérique comprend avantageusement, de part et d'autre de son plan axial, du côté de la maçonnerie, une rainure dans laquelle est insérée une languette d'un matériau foisonnant protégeant les organes de fixation de la dite latte périphérique dans la dite maçonnerie.The peripheral batten advantageously comprises, on either side of its axial plane, on the side of the masonry, a groove in which is inserted a tongue of an abundant material protecting the fastening members of said peripheral batten in said masonry .
Suivant un mode de réalisation préféré, une rainure longitudinale permettant le passage d'un câble électrique est ménagée dans le plan médian du cadre du dormant, sur le flanc de la feuillure ou de la battée, un joint foisonnant étant disposé au fond de la dite rainure.According to a preferred embodiment, a longitudinal groove allowing the passage of an electric cable is formed in the median plane of the frame of the frame, on the side of the rebate or the beating, an expanding joint being disposed at the bottom of said groove.
Le bois dont sont constitués les éléments de la porte a une densité à l'état sec comprise avantageusement entre 600 et 1.000 kg/m3 et de préférence entre 650 et 900 kg/m3.The wood from which the door elements are made has a dry density advantageously between 600 and 1,000 kg / m 3 and preferably between 650 and 900 kg / m 3 .
D'autres particularités et avantages de l'invention ressortiront de la description ci-après de modes de réalisation particuliers de l'invention, référence étant faite aux dessins annexés .Other features and advantages of the invention will emerge from the description below of particular embodiments of the invention, reference being made to the accompanying drawings.
La Fig. 1 est une vue en élévation d'une cloison coupe-feu vitrée de l'invention. La Fig. 2 est une coupe horizontale suivant le plan II-II de la cloison de la Fig. 1.Fig. 1 is an elevational view of a glass fire wall of the invention. Fig. 2 is a horizontal section along the plane II-II of the partition of FIG. 1.
La Fig. 3 est une coupe verticale suivant le plan III- III d'un battant de la cloison de la Fig. 1. La Fig. 4 est une coupe transversale détaillée d'un profilé métallique de recouvrement et de son système de clipsage .Fig. 3 is a vertical section along the plane III-III of a leaf of the partition of FIG. 1. Fig. 4 is a detailed cross section of a metal covering profile and its clipping system.
La Fig. 5 est une vue en coupe de la fermeture entre les deux ouvrants 2, 4 suivant le plan V-V de la Fig. 1. La cloison coupe-feu représentée est fixée à la maçonnerie 1 elle comprend, à titre d'exemple non limitatif, une porte à deux battants 2, 4 ainsi qu'un dormant 6 muni de deux cadres fixes 8, 10 munis de vitrages pare-feu 12. La Fig. 2 permet de prendre connaissance des particularités de la cloison de l'invention.Fig. 5 is a sectional view of the closure between the two openings 2, 4 along the plane V-V of FIG. 1. The firewall shown is fixed to the masonry 1 it includes, by way of nonlimiting example, a double leaf door 2, 4 and a frame 6 provided with two fixed frames 8, 10 provided with glazing firewall 12. FIG. 2 allows you to learn about the features of the partition of the invention.
Les cadres tant des dormants que des ouvrants sont réalisés en bois de même essence, massif et/ou lamellés- collés par collage à plat ou à micro-denture (voir Fig. 5) . L'usage de bois collé permet de travailler avec certaines essences qui ne sont pas disponibles dans les sections demandées. Les micro-dentures élargissent la surface de collage et offrent donc une meilleure stabilité.The frames, both of the frames and of the doors, are made of wood of the same essence, solid and / or laminated - glued by gluing flat or with micro-teeth (see Fig. 5). The use of glued wood makes it possible to work with certain species which are not available in the requested sections. Micro-teeth increase the bonding surface and therefore offer better stability.
Les montants 14 de ces châssis sont assemblés aux traverses 16 par des assemblages à double tenon et enfourchement, ce qui, outre la robustesse de l'assemblage, permet l'obtention de battées et de feuillures continues sur le pourtour de ces cadres, et en conséquence la pose de joints pare-feu 18 sans solution de continuité, comme décrit plus loin.The uprights 14 of these frames are assembled to the crosspieces 16 by double tenon and shank assemblies, which, in addition to the robustness of the assembly, allows obtaining beatings and continuous rebates around the periphery of these frames, and in Consequently, the installation of fire-resistant seals 18 without a continuity solution, as described below.
Comme on peut le constater à la Fig. 2 et à la Fig. 3, les châssis ne comportent aucun élément saillant, si bien que lorsque les deux portes 2, 4 sont fermées, toutes les faces extérieures des éléments de la cloison (à l'exception des vitres) s'étendent dans un plan, soit le plan avant, soit le plan arrière de la cloison. Dans cette perspective, le montant intérieur 14 du dormant 8 est muni d'une battée de frappe 20. Le montant 14 correspondant de l'avant 2 est muni d'une feuillure de frappe 22 de dimensions correspondantes. L'interstice 24 entre le dormant et l'avant a donc la forme d'un Z.As can be seen in FIG. 2 and in FIG. 3, the frames have no protruding element, so that when the two doors 2, 4 are closed, all the outer faces of the elements of the partition (except windows) extend in one plane, either the front plane or the rear plane of the partition. In this perspective, the internal upright 14 of the frame 8 is provided with a striking stroke 20. The corresponding upright 14 from the front 2 is provided with a striking rebate 22 of corresponding dimensions. The gap 24 between the frame and the front therefore has the shape of a Z.
Deux joints foisonnants 18 sont disposés dans cet interstice 24, de façon à apposer une barrière double et symétrique au feu, qu'il survienne du côté de la face avant ou de la face arrière de la cloison.Two abundant joints 18 are arranged in this gap 24, so as to affix a double and symmetrical barrier to fire, whether it occurs on the side of the front face or of the rear face of the partition.
Optionnelle ent, comme représenté sur les figures, les châssis de la cloison sont recouverts par des profilés métalliques 26 à section en U, fixés sur des clips espacés 28. Ces clips 28 sont représentés à la Fig. 4, mais pour la clarté du dessin, ils ne sont pas détaillés sur les Fig. 2 et 3.Optional ent, as shown in the figures, the chassis of the partition are covered by metal sections 26 of U-section, fixed on spaced clips 28. These clips 28 are shown in FIG. 4, but for clarity of the drawing, they are not detailed in FIGS. 2 and 3.
Les branches de la section en U recouvrent partiellement les faces latérales des châssis des ouvrants et du dormant.The branches of the U-shaped section partially cover the lateral faces of the sash and sash frames.
Les joints foisonnants 18 sont disposés dans les battées de frappe 20 et les feuillures de frappe 22. Ces joints, intumescents, ont pour but de se dilater et d'obturer les joints de l'élément, de stopper le passage des flammes et fumées et de diminuer la progression de la combustion.The abundant seals 18 are arranged in the strikes 20 and the striking rebates 22. These intumescent seals are intended to expand and seal the seals of the element, to stop the passage of flames and fumes and to decrease the progression of combustion.
On note que dans l'interstice 24, les branches des profilés 26 ne vont pas jusqu'au fond de la feuillure de frappe 22 ni de la battée de frappe 20, de façon à ne pas masquer les joints foisonnants 18.It is noted that in the gap 24, the branches of the profiles 26 do not go to the bottom of the striking rebate 22 or the striking beating 20, so as not to mask the abundant joints 18.
La conductibilité des profilés métalliques, qui semblerait a priori plutôt défavorable à la résistance au feu de la cloison (voir DE-U-298 19 673 ) , ajoute ici, au contraire, un avantage dans le fait que les extrémités des profilés déclenchent un foisonnement anticipé des joints 18 et offre ainsi une meilleure barrière aux fumées, donc à l'élévation de température et aux flammes.The conductivity of metal profiles, which would seem a priori rather unfavorable to the fire resistance of the partition (see DE-U-298 19 673), adds here, on the contrary, an advantage in that the ends of the profiles trigger an early expansion of the seals 18 and thus offers a better barrier to fumes, therefore to the rise in temperature and to flames.
Les vitres 12 utilisées dans la cloison de l'invention sont des vitres résistant au feu. On utilise des types normalisés (type PYROBEL®, SWISSFLAM® CONTRAFLAM ® ou similaire) résistant à 30 ou 60 minutes ou davantage. Il s'agit de verres feuilletés incorporant des adhésifs foisonnants . Ces vitrages 12 sont posés dans des battées 29, posés sur des cales résistant à haute température (non représentées). Ils sont maintenus par des parcloses 30 vissées, ne dépassant pas du plan de la face de la paroi.The panes 12 used in the partition of the invention are fire resistant panes. Standardized types are used (PYROBEL®, SWISSFLAM® CONTRAFLAM® or similar) resistant to 30 or 60 minutes or more. These are laminated glasses incorporating abundant adhesives. These glazings 12 are placed in battles 29, placed on shims resistant to high temperature (not shown). They are held in place by screwed beads, not exceeding the plane of the face of the wall.
En fond de battée 20 et sur l'épaisseur de la parclose 30 sont disposées des bandes de mousse thermique 31 (type Superwool®) qui maintiennent le vitrage dans le plan médian et permettent son expansion en cas de feu. Le vitrage étant en place, un joint de silicone neutre 33 est injecté dans le volume subsistant. Ce joint maintien la vitre en place même après la destruction en profondeur d'une partie de la cloison.At the bottom of the beating 20 and over the thickness of the glazing bead 30 are arranged strips of thermal foam 31 (Superwool® type) which maintain the glazing in the median plane and allow its expansion in the event of fire. With the glazing in place, a neutral silicone seal 33 is injected into the remaining volume. This seal keeps the glass in place even after the destruction in depth of part of the partition.
La fixation de la cloison de l'invention à la maçonnerie 1 s'effectue de la façon suivante : une latte périphérique 32 est fixée à la maçonnerie 1 par des moyens de fixation 34 connus, tels des vis métalliques. Cette latte 32 est pourvue de deux rainures 36 longitudinales dans lesquelles sont insérées des languettes d'un matériau foisonnant. Ce matériau protège les organes de fixation 34, quel que soit le sens de progression des flammes. Le dormant comprend, du côté où il est en contact avec la maçonnerie 1, une feuillure périphérique 35 qui permet l'introduction de la latte de fixation 32. Une latte de finition 38 munie d'un dent 39 vient refermer la feuillure 35. Un joint foisonnant 18 est disposé sur le flanc de la feuillure 35 de façon à empêcher toute propagation de la flamme. Si l'espace entre la latte de maintien 32 et le cadre extérieur du châssis devient trop important (généralement, au-delà de 4mm), l'étanchéité est complétée par injection de mousse polyuréthane (type FIREFOAM®) . La finition contre la maçonnerie 1 est donc un joint discret, en creux, sans chambranle.The partition of the invention is fixed to the masonry 1 as follows: a peripheral batten 32 is fixed to the masonry 1 by known fixing means 34, such as metal screws. This slat 32 is provided with two longitudinal grooves 36 in which are inserted tongues of an abundant material. This material protects the fixing members 34, whatever the direction of flame progression. The frame comprises, on the side where it is in contact with the masonry 1, a peripheral rebate 35 which allows the introduction of the fastening strip 32. A finishing strip 38 provided with a tooth 39 closes the rebate 35. A abundant seal 18 is arranged on the side of the rebate 35 so as to prevent any propagation of the flame. If the space between the retaining strip 32 and the external frame of the chassis becomes too large (generally, beyond 4 mm), the sealing is completed by injection of polyurethane foam (FIREFOAM® type). The finish against masonry 1 is therefore a discreet, hollow joint, without jamb.
La coupe représentée à la Fig. 3 montre, plus en détail, un battant 2 muni de ses éléments de fermeture inférieur 40 et supérieur 41. Ces éléments sont des pivots à bras déportés. Si le bâtiment dispose d'une centrale de détection d'incendie, les portes 2, 4 peuvent être reliées à un rétenteur magnétique (non représenté) dont l'arrêt est réglable. On prévoit sinon d'office une fermeture automatique.The section shown in FIG. 3 shows, in more detail, a leaf 2 provided with its lower 40 and upper 41 closing elements. These elements are pivots with offset arms. If the building has a fire detection center, doors 2, 4 can be connected to a magnetic retainer (not shown), the stop of which is adjustable. Otherwise, automatic closing is automatically planned.
La pièce 41, totalement déportée, peut être soumise à l'action directe des flammes (suivant le sens de propagation de l'incendie). Or ce type de pièce comprend classiquement un manchon excentrique en nylon permettant un alignement fin de l'axe de pivotement de l'ouvrant. Dans la cloison de l'invention, ce manchon 42 est métallique, ce qui permet d'éviter un bâillement de la porte au moment où la température s'élève.Part 41, completely offset, can be subjected to the direct action of flames (depending on the direction of propagation of the fire). However, this type of part conventionally comprises an eccentric nylon sleeve allowing fine alignment of the pivot axis of the opening. In the partition of the invention, this sleeve 42 is metallic, which makes it possible to avoid yawning of the door when the temperature rises.
Comme on peut le constater par rapport à la Fig. 2, les joints intumescents 18 ne subissent aucune interruption dans leur pose, pas même au niveau de la quincaillerie. Un passage 43 ménagé pour un câble électrique au cœur même de la cloison permet, comme montré à la Fig. 5, le placement d'une serrure électrique 50 simple ou multipoint à gâche réglable (suivant la hauteur de l'ouvrant) dans une mortaise 52 prévue à cet effet. Cette mortaise est tapissée, sur ses deux faces et à l'arrière, par des plaques foisonnantes 54. Le fait de placer une serrure multipoint maintient la porte dans un plan vertical et empêche sa déformation en cas d' incendie .As can be seen from FIG. 2, the intumescent seals 18 are not interrupted in their installation, not even at the hardware. A passage 43 provided for an electric cable at the very heart of the partition allows, as shown in FIG. 5, the placement of an electric lock 50 single or multipoint with adjustable strike (depending on the height of the opening) in a mortise 52 provided for this purpose. This mortise is upholstered, on its two faces and at the back, with abundant plates 54. Placing a multipoint lock keeps the door in a vertical plane and prevents it from being deformed in the event of a fire.
Les effets de la chaleur se faisant sentir surtout vers le haut de la cloison, une languette foisonnante 44 peut être insérée dans l'épaisseur de la frappe supérieure de façon à y ralentir la combustion.The effects of heat being felt especially towards the top of the partition, a bulging tongue 44 can be inserted in the thickness of the upper strike so as to slow combustion there.
La Fig. 4 montre plus en détail une des possibilité de finition de la cloison de l'invention : des clips 28 sont fixés à intervalles sur les montants et les traverses des châssis. Ils sont munis de crochets de retenue 44 assurant, en coopération avec des crochets similaires 46 portés par l'extrémité libre des branches des profilés, un maintien élastique de ces profilés. Comme cela a été précisé plus haut, la résistance au feu obtenue avec la cloison de l'invention ne diffère pas sensiblement entre son exécution avec et sans recouvrement métallique. Suivant les essences sélectionnées, on peut également garder un finition bois. Les châssis, dans ce cas, peuvent être peints, imprégnés ou vernis. Fig. 4 shows in more detail one of the possibilities of finishing the partition of the invention: clips 28 are fixed at intervals on the uprights and the cross members of the chassis. They are provided with retaining hooks 44 ensuring, in cooperation with similar hooks 46 carried by the free end of the branches of the profiles, an elastic retention of these profiles. As was specified above, the fire resistance obtained with the partition of the invention does not differ appreciably between its execution with and without metallic covering. Depending on the species selected, we can also keep a wood finish. The frames, in this case, can be painted, impregnated or varnished.
