According to the invention, the profiles (Po) are made of a thermosetting matrix composite material.

Description

La présente invention concerne une porte notamment coupe-feu destinée à stopper ou pour le moins ralentir la propagation d'un incendie dans une habitation ou dans un local.The present invention relates to a particular fire door designed to stop or at least slow down the spread of a fire in a home or in a room.

Un exemple typique de réalisation d'une porte coupe-feu conventionnelle est présenté sur la Fig. 1. La structure de la porte coupe-feu Pc est constituée d'une âme parallélépipédique Am à faces rectangulaires, fabriquée en plâtre et qui est recouverte par deux feuilles de parement Fp1, Fp2, fabriquées en acier. Chaque feuille de parement Fp présente, sur la Fig. 2, une surface plane délimitée par une paroi principale plane Pp à quatre côtés, ces quatre côtés étant prolongés dans le même plan respectivement par quatre parois P1-P4 de bordure destinées à être repliées à angle droit et du même côté depuis leur ligne de pliement Lp. Sur la Fig. 1, la paroi principale Pp de la feuille de parement Fp1 est appliquée sur une face principale de l'âme Am alors que les quatre parois P1-P4 de bordure sont repliées sur les quatre faces périphériques de ladite âme. La surface de paroi principale Pp de la seconde feuille de parement Fp2 est un peu plus grande de sorte que les quatre parois P1-P4 de bordure recouvrent celles de la feuille de parement Fp1. Les parois latérales sont ensuite fixées, par exemple, par vissage dans les parois périphériques de l'âme.A typical embodiment of a conventional fire door is presented on the Fig. 1 . The structure of the fire door Pc consists of a parallelepiped core Am rectangular faces, made of plaster and which is covered by two facing sheets Fp1, Fp2, made of steel. Each sheet of facing Fp presents, on the Fig. 2 a flat surface delimited by a flat main wall Pp with four sides, these four sides being extended in the same plane respectively by four edge walls P1-P4 intended to be folded at right angles and on the same side from their fold line Lp . On the Fig. 1 , the main wall Pp of the cladding sheet Fp1 is applied to a main face of the core Am while the four edge walls P1-P4 are folded over the four peripheral faces of said core. The main wall surface Pp of the second facing sheet Fp2 is a little larger so that the four edge walls P1-P4 overlap those of the facing sheet Fp1. The side walls are then fixed, for example, by screwing into the peripheral walls of the core.

Les tôles utilisées pour fabriquer les feuilles de parement Fp sont relativement fines et leur épaisseur est de l'ordre de 0.8 à 1 mm. En effet, sous l'effet de la chaleur, produite par un test aux flammes ou un véritable incendie, les parois principales Pp se froissent du fait du différentiel de coefficient de dilatation avec l'âme en plâtre et lorsque ces tôles sont plus épaisses, elles déforment suffisamment la porte coupe-feu qui laisse alors passer le feu entre elle et son dormant.The sheets used to make the facing sheets Fp are relatively thin and their thickness is of the order of 0.8 to 1 mm. Indeed, under the effect of heat, produced by a flame test or a real fire, the main walls Pp wrinkle due to the differential coefficient of expansion with the plaster core and when these sheets are thicker, they deform sufficiently the fire door which then lets fire between her and her frame.

On connaît encore à la lecture du brevet GB-A-842 939 , une structure de porte coupe-feu. Celle-ci est constituée de deux panneaux fabriqués en tôle d'aluminium, tenus parallèlement espacés sur leurs deux bords latéraux, par deux éléments de bord fabriqués en métal et qui présentent en section une géométrie en U définie par une aile intermédiaire prolongée de deux ailes latérales. Les deux bords latéraux de chaque panneau sont repliés sur les deux ailes latérales des éléments de bord. Le volume interne de la porte est rempli par une résine de polyuréthanne.We still know from reading the patent GB-A-842 939 , a fire door structure. This consists of two panels made of aluminum sheet, held parallel to each other at their two lateral edges, by two edge elements made of metal and having in section a U-shaped geometry defined by an extended intermediate wing of two wings. side. The two side edges of each panel are folded over the two side wings of the edge elements. The internal volume of the door is filled with a polyurethane resin.

Considérant cet état de la technique, le demandeur a cherché une solution pour concevoir une porte notamment coupe-feu fabriquée avec des tôles relativement résistantes pour supporter les chocs que subit ladite porte au cours d'un usage normal mais qui cependant puisse conserver sa géométrie originale pour remplir sa fonction de barrage au feu lorsqu'elle est confrontée à un incendie.Considering this state of the art, the applicant has sought a solution to design a door including firewall manufactured with relatively strong sheets to withstand the shocks that undergoes said door during normal use but which, however, can retain its original geometry to fulfill its function as a fire dam when faced with a fire.

A cet effet, est proposée une porte notamment coupe-feu comprenant une âme, deux feuilles de parement disposées en vis-à-vis et de part et d'autre de l'âme, chaque feuille de parement comprenant une paroi principale plane et polygonale, la porte incluant un cadre formé d'une pluralité de profilés aboutés deux à deux de sorte à délimiter le pourtour dudit cadre, chaque profilé présentant en section une géométrie en U définie par une aile intermédiaire prolongée à ses deux extrémités par deux ailes latérales parallèles, et qui sont tournées vers l'extérieur, la paroi principale de chaque feuille de parement reposant sur les ailes latérales tournées d'un même bord dudit cadre, la paroi principale de chaque feuille de parement étant prolongée respectivement par plusieurs de ses côtés par des parois de bordure et qui sont repliées quasi parallèlement à ladite paroi principale afin que ladite feuille de parement puisse être accrochée sur ledit cadre, les ailes latérales tournées d'un même bord dudit cadre étant retenues entre la paroi principale et lesdites parois de bordure; selon l'invention, les profilés sont fabriqués en un matériau composite à matrice thermodurcissable.For this purpose, is proposed a fire door including a core, two facing sheets disposed vis-a-vis and on either side of the core, each facing sheet comprising a flat main wall and polygonal , the door including a frame formed of a plurality of sections abutting two by two so as to delimit the periphery of said frame, each profile having in section a U-shaped geometry defined by an intermediate wing extended at its two ends by two parallel lateral wings , and which are facing outwards, the main wall of each facing sheet resting on the lateral wings turned on the same edge of said frame, the main wall of each facing sheet being extended respectively by several of its sides by border walls and which are folded substantially parallel to said main wall so that said facing sheet can be hung on said frame, the side wings turned on the same edge of said frame being retained between the main wall and said edge walls; according to the invention, the profiles are made of a thermosetting matrix composite material.

Lorsque la porte coupe-feu est soumise à la flamme, la paroi principale se dilate linéairement dans un même plan. La porte coupe-feu conserve sa géométrie plane sur sa face exposée à la chaleur et de ce fait est en mesure de former un barrage au feu.When the fire door is subjected to flame, the main wall expands linearly in the same plane. The fire door retains its flat geometry on its heat exposed side and is therefore able to form a fire dam.

L'épaisseur des feuilles de parement peut être dimensionnée pour que la porte puisse résister aux chocs habituels auxquels elle est soumise régulièrement.The thickness of the facing sheets can be sized so that the door can withstand the usual shocks to which it is subjected regularly.

Les deux ailes latérales du profilé demeurent derrière les deux feuilles de parement et ne sont ainsi pas directement exposées aux effets de la flamme. Elles conservent leur géométrie et permettent de maintenir la planéité de la porte coupe-feu en cas d'incendie pour qu'elle puisse faire obstacle à la propagation du feu.The two lateral wings of the profile remain behind the two facing sheets and are thus not directly exposed to the effects of the flame. They retain their geometry and maintain the flatness of the fire door in case of fire so that it can hinder the spread of fire.

Selon une caractéristique additionnelle de l'invention, le matériau composite à matrice thermodurcissable est un polyester qui est chargé en fibres de verre.According to an additional characteristic of the invention, the thermosetting matrix composite material is a polyester which is loaded with glass fibers.

Les profilés fabriqués dans cette matière ne se déforment qu'extrêmement peu à la chaleur.The profiles made in this material deform only extremely little heat.

Selon une caractéristique additionnelle de l'invention, des profilés de renfort présentant en section une géométrie en U sont montés respectivement dans les profilés constitutifs du cadre.According to an additional characteristic of the invention, reinforcing profiles having a U-shaped geometry in section are respectively mounted in the constituent sections of the frame.

La rigidité du cadre est accrue et par conséquent la rigidité de la porte également.The rigidity of the frame is increased and therefore the rigidity of the door also.

Selon une caractéristique additionnelle de l'invention, des joints présentant en section une géométrie en U sont interposés entre au moins certains profilés de renfort et les profilés correspondants qui sont constitutifs du cadre, chaque joint étant pourvu de deux lèvres et dont au moins une fait saillie de chaque côté du profilé de renfort correspondant.According to an additional characteristic of the invention, joints having a U-shaped geometry in section are interposed between at least some reinforcement sections and the corresponding sections constituting the frame, each joint being provided with two lips and at least one of which projection on each side of the corresponding reinforcing profile.

Ces joints servent à procurer une étanchéité entre la porte et son dormant ou, le cas échéant, avec un seuil de porte. Les profilés de renfort bloquent les joints dans les profilés en U du cadre et les maintiennent correctement en place.These seals serve to provide a seal between the door and its frame or, where appropriate, with a door sill. The reinforcement profiles block the joints in the U-profiles of the frame and hold them securely in place.

Selon une caractéristique additionnelle de l'invention, des équerres réunissent respectivement au niveau de leurs jointures, deux profilés constitutifs du cadre, chaque équerre étant appliquée sous les ailes intermédiaires de deux profilés jointifs.According to an additional feature of the invention, brackets join respectively at their joints, two sections constituting the frame, each bracket being applied under the intermediate wings of two joined profiles.

La présence de ces équerres renforce la structure du cadre et par conséquent la rigidité de la porte également.The presence of these brackets reinforces the structure of the frame and therefore the rigidity of the door as well.

Selon une caractéristique additionnelle de l'invention, un matériau de remplissage remplit le volume intérieur du cadre fermé par ses deux feuilles de parement.According to an additional characteristic of the invention, a filling material fills the interior volume of the closed frame by its two facing sheets.

Le matériau de remplissage forme ainsi l'âme de la porte en lui procurant la rigidité requise par sa fonction. Elle accroît également la masse de ladite porte. Le matériau de remplissage est avantageusement une mousse expansive injectée dans le volume délimité dans ledit cadre. L'isolation thermique et acoustique est également accrue.The filling material thus forms the core of the door, providing it with the rigidity required by its function. It also increases the mass of said door. The filling material is advantageously an expansive foam injected into the volume defined in said frame. Thermal and acoustic insulation is also increased.

Selon une caractéristique additionnelle de l'invention, des joints intumescents sont fixés sur les faces externes des profilés de renfort, lesdites faces externes étant celles tournées vers le dormant dans lequel est susceptible d'être posée ladite porte ou vers un seuil de porte.According to an additional feature of the invention, intumescent joints are fixed on the outer faces of the reinforcing profiles, said external faces being those facing the frame in which may be placed said door or towards a door sill.

Sous l'effet de la chaleur, le joint intumescent se dilate et vient obstruer l'interstice subsistant entre la porte coupe-feu et son dormant, entre la porte coupe-feu et le seuil de porte.Under the effect of heat, the intumescent gasket expands and clogs the gap between the fire door and its frame, between the fire door and the door sill.

Selon une caractéristique additionnelle de l'invention, des gonds sont fixés sur un profilé de renfort correspondant, par l'intermédiaire d'au moins une vis qui traverse ledit profilé pour prendre ancrage dans l'aile intermédiaire d'un des profilés constitutifs du cadre.According to an additional characteristic of the invention, hinges are fixed on a corresponding reinforcement profile, by means of at least one screw which passes through said profile to anchor in the intermediate wing of one of the constituent sections of the frame. .

Les gonds sont fermement tenus dans la porte.The hinges are firmly in the door.

La porte coupe-feu 100 présentée sur la Fig. 3 est destinée à interdire ou du moins retarder la propagation du feu entre deux pièces d'un bâtiment et, notamment, un bâtiment destiné à accueillir du public. L'aptitude à la résistance au feu d'une telle porte est définie actuellement par la norme NF 227.The fire door 100 presented on the Fig. 3 is intended to prohibit or at least delay the spread of fire between two rooms of a building and, in particular, a building intended to accommodate the public. The fire resistance ability of such a door is currently defined by standard NF 227.

La structure de la porte coupe-feu 100 est définie principalement par un cadre Cd, deux feuilles de parement Ft1 et Ft2 tournées en vis-à-vis et montées de part et d'autre dudit cadre, des joints Jt montés sur au moins trois côtés du cadre Cd, des profilés Pf de renfort montés autour du cadre Cd, ainsi que, le cas échéant, de la quincaillerie telle que des paumelles destinées à fixer l'ouvrant 100 sur un dormant, une serrure.The structure of the fire door 100 is defined mainly by a frame Cd, two facing sheets Ft1 and Ft2 facing each other and mounted on either side of said frame, Jt seals mounted on at least three sides of frame Cd, profiles Pf reinforcement mounted around the frame Cd, and, if necessary, the hardware such as hinges for securing the opening 100 on a frame, a lock.

Le cadre Cd est constitué, sur la Fig. 4, de quatre profilés Po de section en U et qui sont assemblés à angle droit, par l'intermédiaire d'équerres Eq. Chaque profilé Po se compose ainsi d'une aile intermédiaire Ai prolongée à ses deux extrémités par deux ailes latérales Al1 et Al2 parallèles, et qui sont tournées vers l'extérieur. Les deux extrémités des profilés sont biseautées à 45 ° pour s'abouter parfaitement. Les profilés Po sont préférentiellement fabriqués en un matériau composite à matrice thermodurcissable, tel que le polyester qui est préférentiellement renforcé par des fibres de verre. Un tel profilé polyester est, par exemple, fabriqué par pultrusion par la société Tecnipul ®. Ce matériau procure relativement une bonne rigidité et une tenue au feu suffisante pour l'usage requis. Cette matière ne brûle qu'au contact direct avec une flamme. Les profilés fabriqués dans cette matière ne se déforment qu'extrêmement peu sous l'effet de la chaleur.The Cd frame is constituted, on the Fig. 4 of four U section profiles and which are assembled at a right angle, through brackets Eq. Each profile Po is thus composed of an intermediate wing Ai extended at its two ends by two parallel lateral wings Al1 and Al2, which are turned outwards. Both ends of the profiles are chamfered at 45 ° to fit perfectly. The profiles Po are preferably made of a thermosetting matrix composite material, such as polyester which is preferably reinforced with glass fibers. Such a polyester profile is, for example, manufactured by pultrusion by the company Tecnipul ®. This material provides relatively good rigidity and fire resistance sufficient for the required use. This material burns only in direct contact with a flame. The profiles made in this material deform only extremely little under the effect of heat.

Chaque équerre Eq réunit deux extrémités jointives de deux profilés Po contigus. Chaque équerre Eq est appliquée sous les ailes intermédiaires Ai de deux profilés Po jointifs. Un moyen d'assemblage, tel que des boulons Bo, réunit les deux parois constitutives des équerres Eq avec l'aile intermédiaire Ai des profilés Po aboutés. Les équerres sont préférentiellement fabriquées en métal.Each Eq square joins two contiguous ends of two contiguous Po profiles. Each square Eq is applied under the intermediate wings Ai of two joined profiles Po. An assembly means, such as bolts Bo, joins the two constituent walls of brackets Eq with the intermediate flange Ai of abutting profiles Po. The brackets are preferably made of metal.

La feuille de parement Ft présentée sur la Fig. 5 est destinée à être montée sur chacune des deux faces principales du cadre. La feuille de parement Ft est fabriquée en métal, par exemple en acier inoxydable. Son épaisseur est de l'ordre de 2 à 3 mm pour résister aux chocs usuels auxquels est exposée une porte coupe-feu dans un usage normal, par exemple, les chocs de chariots roulants, l'impact de chaussures pour ouvrir ladite porte coupe-feu.The sheet of facing Ft presented on the Fig. 5 is intended to be mounted on each of the two main faces of the frame. The facing sheet Ft is made of metal, for example stainless steel. Its thickness is of the order of 2 to 3 mm to withstand the usual shocks to which a fire door is exposed in normal use, for example, the impacts of trolleys, the impact of shoes to open said door cutter. traffic light.

La feuille de parement Ft présente une surface plane délimitée par une paroi principale Pp polygonale et à quatre côtés sur cette Fig. 5, ces quatre cotés étant prolongés dans le même plan respectivement par quatre parois P1-P4 de bordure présentant globalement une géométrie rectangulaire.The facing sheet Ft has a flat surface delimited by a main wall Pp polygonal and four sides on this Fig. 5 these four sides being extended in the same plane respectively by four walls P1-P4 border generally having a rectangular geometry.

Sur cette Fig. 5, les trois parois P1, P2 et P4, c'est-à-dire respectivement la paroi haute P1 ainsi que les deux parois latérales P2 et P4, dans la position de pose de la feuille de parement, sont repliées à 180 ° autour d'une zone de repliement rayonnée Zp pour prendre leur position visible sur la Fig. 6 et dans laquelle elles sont disposées parallèlement à la paroi principale Pp. Sur la Fig. 5, les bords latéraux de la paroi haute P1 sont biseautés à 45°. Il en est de même pour les deux bords latéraux hauts des deux parois P2 et P4, c'est-à-dire leurs bords situés dans la partie haute de la Fig. 5 et qui sont biseautés à 45°. Ainsi, en repliant les parois P1, P2 et P4, leurs bords latéraux s'aboutent pratiquement, sans se chevaucher, comme le montre la vue en détail.On this Fig. 5 , the three walls P1, P2 and P4, that is to say respectively the upper wall P1 and the two side walls P2 and P4, in the laying position of the facing sheet, are folded at 180 ° around a radiated folding zone Zp to take their visible position on the Fig. 6 and in which they are arranged parallel to the main wall Pp. Fig. 5 , the side edges of the high wall P1 are chamfered at 45 °. It is the same for the two high side edges of the two walls P2 and P4, that is to say their edges located in the upper part of the Fig. 5 and which are bevelled at 45 °. Thus, by folding the walls P1, P2 and P4, their side edges practically abut, without overlapping, as shown in detail view.

Grâce à cette construction, il est possible de monter chacune des deux feuilles de parement Ft en faisant glisser sa paroi principale Pp sur une face principale du cadre de sorte à faire glisser les trois parois P1, P2 et P4 derrière les ailes latérales de trois profilés correspondant dudit cadre. Cette situation est visible partiellement sur la Fig. 3 où l'on voit la paroi haute P1 de la feuille de parement Ft1 retenue derrière l'aile latérale Al1 du cadre Cd. Dans ces conditions, la feuille de parement Ft est fixée sur le cadre Cd. Sa paroi principale plane Pp peut se dilater dans un plan car ses bords ne sont pas bridés. Ainsi la porte coupe-feu exposée à la flamme ne se vrille pas. Elle remplit donc sa fonction de faire barrière au feu.With this construction, it is possible to mount each of the two facing sheets Ft by sliding its main wall Pp on a main face of the frame so as to slide the three walls P1, P2 and P4 behind the side wings of three profiles corresponding of said frame. This situation is partially visible on the Fig. 3 where we see the high wall P1 of the cladding sheet Ft1 retained behind the side wing Al1 of the frame Cd. Under these conditions, the cladding sheet Ft is fixed on the frame Cd. Its main flat wall Pp can be dilated. in a plane because its edges are not clamped. Thus the fire door exposed to the flame does not twist. It thus fulfills its function of making fire barrier.

Sur la Fig. 6, la paroi basse P3 est faiblement repliée tout en étant tournée de l'autre côté des parois P1, P2 et P4, d'un angle de quelques degrés, pour, et en référence à la Fig. 3, dévoyer les gouttes de condensation, les eaux de lavage et aussi accroître la rigidité de la feuille de parement. On notera que cette paroi basse P3, dans un mode de réalisation montré sur la partie droite de la Fig. 5, n'est pas repliée. Par ailleurs, les deux parois latérales P2 et P4 peuvent descendre jusqu'au niveau de la partie basse de la feuille de parement Ft, comme cela est montré sur la partie droite de la Fig. 5.On the Fig. 6 , the lower wall P3 is slightly folded while being turned on the other side of the walls P1, P2 and P4, by an angle of a few degrees, for and with reference to the Fig. 3 , divert condensation drops, wash water and also increase the rigidity of the facing sheet. It will be noted that this low wall P3, in one embodiment shown on the right side of the Fig. 5 , is not folded. Furthermore, the two side walls P2 and P4 can go down to the level of the lower part of the facing sheet Ft, as shown on the right side of the Fig. 5 .

Les feuilles de parement Ft sont ensuite peintes et préférentiellement par thermo-laquage. Elles sont alors prêtes à être posées. Les deux feuilles de parement peuvent être peintes de deux couleurs différentes.The facing sheets Ft are then painted and preferably by heat-lacquering. They are then ready to be asked. The two facing sheets can be painted in two different colors.

Sur la Fig. 7, des joints Jt sont insérés dans au moins trois des côtés, c'est-à-dire dans le côté supérieur et dans les deux côtés latéraux, du cadre Cd équipé de ses deux feuilles de parement Ft1 et Ft2. Chaque joint T est formé d'un profilé qui présente en section une géométrie en U et dont les deux ailes latérales, prolongeant une aile intermédiaire, forment les deux lèvres du joint. Les deux extrémités de chaque joint sont biseautées à 45° pour que ledit joint puisse s'abouter avec un autre voisin.On the Fig. 7 , seals Jt are inserted in at least three of the sides, that is to say in the upper side and in the two lateral sides of the frame Cd equipped with its two facing sheets Ft1 and Ft2. Each seal T is formed of a profile which has in section a U-shaped geometry and whose two lateral wings, extending an intermediate wing, form the two lips of the joint. The two ends of each joint are chamfered at 45 ° so that said seal can be joined with another neighbor.

Sur la Fig. 8, chaque joint Jt est calé contre l'aile intermédiaire Ai des profilés Po constitutifs du cadre Cd, laissant la possibilité aux deux lèvres dudit joint d'épouser le profil d'un dormant D dans lequel la porte coupe-feu 100 est susceptible d'être montée.On the Fig. 8 each seal Jt is wedged against the intermediate flange Ai of the constituent profiles Po of the frame Cd, leaving the possibility to the two lips of said seal to match the profile of a frame D in which the fire door 100 is likely to to be mounted.

Le dormant est constitué de plusieurs profilés métalliques assemblés entre eux et qui sont fixés dans l'encadrement d'une porte, par exemple à l'aide de chevilles ou de tirefonds Tf, comme cela est montré sur la Fig. 9.The frame consists of several metal profiles assembled together and which are fixed in the frame of a door, for example using dowels or lag bolts Tf, as shown on the Fig. 9 .

Les quatre profilés de renfort Pf sont respectivement montés dans les quatre profilés Po constitutifs du cadre Cd, c'est-à-dire sur tout son pourtour et, le cas échéant dans chaque joint Jt. Les profilés Pf servent ainsi à procurer au cadre Cd la rigidité suffisante pour former la structure porteuse de la porte coupe-feu 100. Ils servent également à fixer les joints Jt sur ledit cadre en les maintenant correctement conformés. Les profilés Pf sont préférentiellement fabriqués en métal, par exemple en acier inoxydable.The four reinforcing profiles Pf are respectively mounted in the four profiles constituting Po Cd frame, that is to say all over its periphery and, where appropriate in each joint Jt. The profiles Pf thus serve to provide the frame Cd with sufficient rigidity to form the supporting structure of the fire door 100. They also serve to fix the joints Jt on said frame by keeping them properly shaped. The profiles Pf are preferably made of metal, for example stainless steel.

Sur les Figs. 8 et 9, chaque profilé Pf présente globalement en section une géométrie en C. Sur la Fig. 9, des vis V de direction parallèle aux feuilles de parement Ft traversent les profilés Pf pour venir les fixer dans l'aile intérieure Ai des profilés Po correspondants constitutifs du cadre Cd. Sur les Figs. 8 et 9, chaque joint Jt est appliqué, par l'intermédiaire d'un profilé Pf correspondant sur l'aile intermédiaire Ai d'un profilé Po constitutif du cadre Cd. Les deux lèvres dudit joint font saillie hors du profilé Pf pour venir en contact avec le profil du dormant D pour procurer une étanchéité à l'eau et à l'air et aussi pour faire barrière à la propagation de la flamme. Dans une variante de réalisation, non représentée, une seule lèvre fait saillie hors du profilé Pf pour venir en contact avec le profil du dormant D.On the Figs. 8 and 9 each profile Pf generally has a C-shaped geometry in section. Fig. 9 screws V of direction parallel to the facing sheets Ft pass through the profiles Pf to be fixed in the inner wing Ai of corresponding profiles Po corresponding to the frame Cd. Figs. 8 and 9 , each seal Jt is applied, via a corresponding profile Pf on the intermediate wing Ai of a profile Po constituting the frame Cd. The two lips of said seal project out of the profile Pf to come into contact with the profile of the frame D to provide water and airtightness and also to prevent the propagation of the flame. In an alternative embodiment, not shown, a single lip protrudes out of the profile Pf to come into contact with the profile of the frame D.

Pour parfaire la capacité de la porte coupe-feu 100 à arrêter la flamme, des joints intumescents Jit, encore appelés joints thermo-gonflants, sont fixés sur les faces externes des profilés Pf, c'est-à-dire sur ses faces tournées vers le dormant ou vers un seuil de porte Sp. Sous l'effet de la chaleur, le joint thermo-gonflant Jit se dilate et vient obstruer l'interstice subsistant entre la porte coupe-feu 100 et son dormant D, entre la porte coupe-feu 100 et le seuil de porte Sp. Il se présente préférentiellement sous la forme d'une bande de matière de section rectangulaire. Il est fabriqué, par exemple, en élastomère synthétique.To perfect the ability of the fire door 100 to stop the flame, Jit intumescent joints, also called heat-expansion joints, are fixed on the outer faces of the profiles Pf, that is to say on its faces facing the frame or to a door sill Sp. Under the effect of heat, the heat-swelling Jit seal expands and clogs the gap between the fire door 100 and its frame D, between the door-cutter Fire 100 and the door sill Sp. It is preferably in the form of a strip of material of rectangular section. It is manufactured, for example, synthetic elastomer.

Sur la Fig. 3, un matériau de remplissage remplit le volume intérieur du cadre fermé latéralement par ses deux feuilles de parement Ft1 et Ft2. Ce matériau de remplissage est avantageusement de la mousse expansive Mx qui a été injectée dans ledit cadre Cd. La mousse expansive Mx est injectée au travers d'un orifice prévu dans un des profilés Po constitutifs dudit cadre. A l'issue de sa solidification, la mousse alvéolaire Mx forme l'âme de la porte coupe-feu 100 en lui procurant la rigidité requise par sa fonction, notamment, en renforçant la rigidité du cadre Cd, en procurant un appui pour les deux feuilles de parement Ft et en collant celles-ci sur ladite âme durcie. La mousse expansive est par exemple, une mousse de polyuréthane. Elle accroît également la masse de ladite porte coupe-feu 100.On the Fig. 3 , a filling material fills the interior volume of the frame closed laterally by its two facing sheets Ft1 and Ft2. This filling material is advantageously expansive foam Mx which has been injected into said frame Cd. The expansive foam Mx is injected through an orifice provided in one of the constituent sections Po of said frame. At the end of its solidification, the cellular foam Mx forms the core of the fire door 100 by providing it with the required rigidity by its function, in particular, by reinforcing the rigidity of the frame Cd, providing support for the two facing sheets Ft and gluing them on said hardened core. The expansive foam is, for example, a polyurethane foam. It also increases the mass of said fire door 100.

On notera que l'ébauche de la porte ainsi construite peut être peinte en une seule couleur à ce stade de sa fabrication.It should be noted that the blank of the door thus constructed can be painted in a single color at this stage of its manufacture.

Sur la Fig. 10, une partie d'un gond Gd est fixée sur un côté latéral de la porte coupe-feu 100. Il est destiné à coopérer avec une partie complémentaire du gond fixé sur le dormant D. Le gond Gd est fixé sur un profilé de renfort Pf correspondant, par l'intermédiaire d'au moins une vis V qui traverse ledit profilé Pf pour prendre ancrage dans l'aile intermédiaire Ai d'un des profilés Po constitutifs du cadre Cd.On the Fig. 10 , part of a hinge Gd is fixed on a lateral side of the fire door 100. It is intended to cooperate with a complementary part of the hinge fixed on the frame D. The hinge Gd is fixed on a reinforcement profile Pf corresponding, through at least one screw V which passes through said profile Pf for anchoring in the intermediate wing Ai of one of the profiles constituting Po Cd frame.

Sur la Fig. 11, une serrure Sr est montée dans le côté latéral opposé à celui qui porte les gonds. Une réservation Rs est délimitée dans le volume intérieur du cadre Cd pourvu de ses deux feuilles de parement Ft pour réceptionner et monter la serrure Sr. La réservation Rs est définie par la présence de plaques ou des profilés jouxtant les deux feuilles de parement Ft pour dévoyer localement l'expansion de la mousse dans ledit volume intérieur. On utilise préférentiellement trois profilés Po, identiques à ceux utilisés pour la fabrication du cadre Cd et qui sont aboutés à angle droit pour délimiter ladite réservation.On the Fig. 11 , a lock Sr is mounted in the lateral side opposite to that which carries the hinges. A reservation Rs is delimited in the interior volume of the frame Cd provided with its two facing sheets Ft to receive and mount the lock Sr. The reservation Rs is defined by the presence of plates or profiles next to the two sheets of facing Ft to mislead locally expanding the foam in said interior volume. Three profiles Po, identical to those used for the manufacture of the frame Cd and which are abutted at right angles to delimit said reservation, are preferably used.

On remarquera, notamment sur les Figs 8 et 9, que les lèvres des joints Jt sont interposées entre, soit la porte coupe-feu 100 et son dormant D, soit entre la porte coupe-feu 100 et le seuil de porte Sp. Les feuilles de parement Ft ne touchent donc pas, ni le dormant D, ni le seuil de porte Sp. Ainsi, il n'y a pas de pont thermique entre la porte coupe-feu et son dormant ou le seuil de porte.We will notice, especially on Figs 8 and 9 that the lips of the joints Jt are interposed between either the fire door 100 and its frame D, or between the fire door 100 and the door sill Sp. The facing sheets Ft thus do not touch, nor the D dormant, or the door sill Sp. Thus, there is no thermal bridge between the fire door and its frame or the door sill.

La porte coupe-feu de l'invention se déforme de manière homothétique lorsqu'elle est soumise à la chaleur d'un incendie. Elle forme une barrière étanche au feu selon la norme en vigueur.The fire door of the invention is deformed homothetically when subjected to the heat of a fire. It forms a fireproof barrier according to the standard in force.

Elle est relativement simple à fabriquer.It is relatively simple to manufacture.

La porte coupe-feu de l'invention peut encore être équipée d'accessoires que l'on retrouve typiquement sur une porte. La porte coupe-feu peut ainsi être pourvue d'un système de verrouillage de sa position par électro-aimant, d'une serrure anti panique à barre de déverrouillage.The fire door of the invention can still be equipped with accessories that are typically found on a door. The fire door can thus be provided with a locking system of its position by electromagnet, an anti-panic lock with unlocking bar.

Grâce à sa conception, la porte coupe-feu de l'invention peut aussi être utilisée, du fait de la présence de mousse alvéolaire entre les deux feuilles de parement qui ne sont pas en contact, comme porte isotherme, comme porte acoustique du fait de la présence d'une mousse alvéolaire entre les deux feuilles de parement et qui absorbe les vibrations. En l'équipant de feuilles de parement encore plus épaisses, elle peut être utilisée comme porte blindée.Thanks to its design, the fire door of the invention can also be used, because of the presence of cellular foam between the two facing sheets which do not are not in contact, as isothermal door, as acoustic door due to the presence of a cellular foam between the two facing sheets and which absorbs vibrations. By equipping it with even thicker facing sheets, it can be used as an armored door.

La porte coupe-feu de l'invention est fabriquée sans soudure et de ce fait est relativement simple à construire.The fire door of the invention is manufactured without welding and therefore is relatively simple to build.

La porte coupe-feu de l'invention peut aussi être utilisée en tant que trappe d'accès vers une coursive, des combles, un vide sanitaire, un parking. La trappe d'accès est en principe disposée horizontalement.The fire door of the invention can also be used as an access door to a corridor, attics, crawl space, parking. The access hatch is normally arranged horizontally.
