Description

Dispositif de cloison murale coupe-feu et ensemble de cloison murale avec bloc-porte comprenant un tel dispositif  Firewall wall partition device and wall partition assembly with door block comprising such a device
La présente invention concerne le domaine du bâtiment, notamment du bâtiment de haute sécurité, et plus particulièrement le domaine des cloisons murales incluant une ouverture recevant un bloc-porte coupe feu et a pour objet un dispositif de cloison murale et un ensemble de cloison murale avec bloc-porte. The present invention relates to the field of the building, in particular the high security building, and more particularly to the field of wall partitions including an opening receiving a fire door block and has for object a wall partition device and a wall partition assembly with Door block.
On connaît déjà des structures de cloisons murales, mises en œuvre dans les bâtiments de haute sécurité tels que ceux des centrales nucléaires, comprenant une cloison murale dans laquelle est pratiquée une ouverture permettant le passage à travers celle-ci et étant fermée par un bloc- porte coupe feu constitué par un cadre dormant métallique ou en acier fixé dans cette dernière et par un ouvrant ou vantail monté pivotant dans le cadre dormant.  Already known wall partition structures, implemented in high-security buildings such as those of nuclear power plants, comprising a wall partition in which is made an opening allowing passage therethrough and being closed by a block- fire door consisting of a metal or steel fixed frame fixed in the latter and an opening or wing pivotally mounted in the fixed frame.
De telles structures de cloison murale sont généralement réalisées en béton. Toutefois, ce type de structure est d'un poids élevé et sa mise en œuvre dans certaines zones d'un bâtiment, notamment de centrale nucléaire, est, pour cause de mauvaise accessibilité, délicate, voire risquée. En outre, une fois le béton coulé, il est impossible de modifier la cloison, dans sa forme ou son étendue. Enfin, une telle cloison en béton a tendance au cours du temps ou lors de secousses sismiques à se fissurer affaiblissant d'autant la cloison.  Such wall partition structures are generally made of concrete. However, this type of structure is of a high weight and its implementation in some areas of a building, including nuclear power plant, is due to poor accessibility, delicate or even risky. In addition, once poured concrete, it is impossible to change the partition, in its shape or extent. Finally, such a concrete partition has a tendency over time or during seismic shaking to crack weakening all the partition.
La présente invention a pour objet de remédier à ces inconvénients en proposant un dispositif de cloison murale d'un poids réduit par rapport aux cloisons en béton actuelles, permettant sa mise en œuvre et son installation de façon aisée quelque soit sa localisation dans le bâtiment et présentant l'avantage d'être modulaire, tout en offrant une plus grande fiabilité que les cloisons actuelles.  The present invention aims to overcome these disadvantages by proposing a wall partition device of a reduced weight compared to current concrete partitions, allowing its implementation and its installation easily regardless of its location in the building and having the advantage of being modular, while offering greater reliability than current partitions.
A cet effet, la présente invention, qui a pour objet un dispositif de cloison murale coupe-feu destiné à être installée dans un bâtiment, plus particulièrement un bâtiment de haute sécurité, ledit dispositif comprenant une cloison murale et une ouverture destinée à recevoir un bloc-porte, se caractérise essentiellement en ce que ladite cloison murale comprend une ossature métallique constituée par une première série de profilés métalliques de section transversale en U et par une seconde série de profilés métalliques de section transversale en C, ladite section transversale en C étant définie comme une section transversale en U dont chaque aile du U se prolonge à son extrémité libre vers l'intérieur du U par un retour interne, lesdits profilés étant assemblés entre eux en formant un cadre externe rectangulaire délimitant l'étendue surfacique de la cloison et un cadre interne rectangulaire s 'étendant sensiblement dans le même plan que le cadre externe à l'intérieur de ce dernier et délimitant ladite ouverture de réception du bloc-porte et en ce que, à l'état monté desdits cadres dans un plan vertical leurs côtés verticaux sont formés par les profilés métalliques en C et leurs côtés horizontaux sont formés par les profilés métalliques en U et en ce que ladite cloison comprend au moins deux panneaux coupe-feu adaptés pour recouvrir, autour de ladite ouverture de réception, chaque côté du plan contenant ladite ossature. For this purpose, the present invention, which relates to a firewall wall partition device intended to be installed in a building, more particularly a building of high security, said device comprising a wall partition and an opening for receiving a block -door, is essentially characterized in that said wall partition comprises a metal frame consisting of a first series of metal sections of U cross section and a second series of profiles C-section metal cross-section, said C cross-section being defined as a U-shaped cross section, each U-flange of which extends at its free end towards the inside of the U by an internal return, said sections being joined together forming a rectangular outer frame delimiting the surface area of the partition and a rectangular internal frame extending substantially in the same plane as the outer frame inside the latter and delimiting said receiving opening of the door block and in that , in the mounted state of said frames in a vertical plane their vertical sides are formed by the C-shaped metal sections and their horizontal sides are formed by the U-shaped metal sections and in that said partition comprises at least two adapted fire-resistant panels to cover, around said receiving opening, each side of the plane containing said framework.
La présente invention a également pour objet un ensemble de cloison murale avec bloc-porte comprenant une structure de cloison murale et un bloc-porte comportant un cadre dormant et un ouvrant, se caractérisant essentiellement en ce que la cloison murale dudit ensemble consiste en un dispositif de cloison murale coupe feu selon la présente invention et en ce qu'il comprend eune interface permettant la liaison entre le bloc-porte et la cloison murale dudit dispositif.  The present invention also relates to a wall partition assembly with a door block comprising a wall partition structure and a door block comprising a frame and a sash, characterized essentially in that the wall partition of said assembly consists of a device Firewall wall partition according to the present invention and in that it comprises an interface allowing the connection between the door block and the wall partition of said device.

FIG. 5 shows a perspective view of the assembly represented in FIG. 1, - Figure 6 shows a sectional view along A-A of the assembly shown in Figure 1.
Les figures montrent un dispositif de cloison murale coupe-feu destiné à être installée dans un bâtiment, plus particulièrement un bâtiment de haute sécurité, ledit dispositif comprenant une cloison 1 murale et une ouverture 2 destinée à recevoir un bloc-porte 3.  The figures show a firewall wall partition device intended to be installed in a building, more particularly a high security building, said device comprising a wall partition 1 and an opening 2 intended to receive a door block 3.
Conformément à la présente invention, la cloison 1 comprend une ossature 4, 5 métallique constituée par une première série de profilés métalliques 4 de section transversale en U et par une seconde série de profilés métalliques 5 de section transversale en C, ladite section transversale en C étant définie comme une section transversale en U dont chaque aile 50 du U se prolonge à son extrémité libre vers l'intérieur du U par un retour interne 51, lesdits profilés étant assemblés entre eux en formant un cadre externe rectangulaire délimitant l'étendue surfacique de la cloison 1 et un cadre interne rectangulaire s 'étendant sensiblement dans le même plan que le cadre externe à l'intérieur de ce dernier et délimitant ladite ouverture 2 de réception du bloc-porte 3 (notamment figures 2 et 3).  In accordance with the present invention, the partition 1 comprises a metal frame 4, 5 constituted by a first series of metal sections 4 of U cross section and by a second series of metal sections 5 of C cross section, said C cross section. being defined as a U-shaped cross-section in which each wing 50 of the U extends at its free end towards the inside of the U by an internal return 51, said profiles being assembled together forming a rectangular outer frame delimiting the surface area of the the partition 1 and a rectangular internal frame extending substantially in the same plane as the outer frame inside the latter and defining said opening 2 for receiving the door block 3 (in particular Figures 2 and 3).
Toujours conformément à l'invention, à l'état monté des cadres externe et interne dans un plan vertical leurs côtés verticaux sont formés par les profilés métalliques 5 en C et leurs côtés horizontaux supérieur et inféieur sont formés par les profilés métalliques 4 en U (notamment figures 2 et 3). En outre, la cloison 1 murale comprend au moins deux panneaux 6 coupe-feu adaptés pour recouvrir, autour de ladite ouverture 2 de réception, chaque côté du plan contenant ladite ossature, ce afin d'assurer la protection au feu de cette dernière et de la cloison 1 (figures 1, 4, 5).  Still according to the invention, in the mounted state of the outer and inner frames in a vertical plane their vertical sides are formed by the metal profiles 5 in C and their upper and lower horizontal sides are formed by the metal profiles 4 U ( in particular FIGS. 2 and 3). In addition, the wall partition 1 comprises at least two firebreak panels 6 adapted to cover, around said receiving opening 2, each side of the plane containing said frame, in order to ensure the fire protection of the latter and partition 1 (FIGS. 1, 4, 5).
Les retours internes 51 des profilés métalliques 5 en C permettent d'accroître notablement l'inertie mécanique de ces derniers.  Internal returns 51 C metal profiles 5 can significantly increase the mechanical inertia of the latter.
Dans une forme de réalisation préférentielle de l'invention l'ouverture du U de chaque profilé métallique 4 en U du cadre externe peut être prévue pour être supérieure à la largeur de chaque profilé métallique 5 en C. Une telle ouverture du U est définie comme étant l'écartement entre les deux ailes 41 du U fixées à son fond 42 (notamment figures 2 et 3).  In a preferred embodiment of the invention the opening of the U of each U-shaped metal section 4 of the external frame may be provided to be greater than the width of each C-shaped metal section. Such an opening of the U is defined as being the spacing between the two wings 41 of the U fixed to its bottom 42 (in particular Figures 2 and 3).
Dans un mode de réalisation préférentiel, le cadre externe peut être constitué, à l'état monté dans un plan vertical, par deux profilés métalliques 5 en C formant ses deux côtés opposés verticaux, et deux profilés métalliques 4 en U formant ses deux côtés opposés horizontaux supérieur et inférieur. En outre, les extrémités des profilés métalliques 5 en C verticaux peuvent être insérées chacune entre les deux ailes du profilé métallique 4 en U supérieur et inférieur correspondant en venant en appui contre le fond de ce dernier (notamment figures 2 et 3). In a preferred embodiment, the outer frame may be constituted, in the mounted state in a vertical plane, by two C-shaped metal sections 5 forming its two opposite vertical sides, and two U-shaped metal sections 4 forming its two opposite sides. horizontal upper and lower. In addition, the ends of the metal sections 5 in C vertical can be inserted between each of the two wings of the metal section 4 U upper and lower corresponding bearing against the bottom of the latter (in particular Figures 2 and 3).
Dans un mode de réalisation préférentiel du cadre interne, à l'état monté dans un plan vertical, celui-ci peut être constitué, d'une part, par deux profilés métalliques 4 en C formant ses deux côtés opposés verticaux, les extrémités desdits profilés métalliques 4 en C pouvant être insérées chacune entre les deux ailes 41 du profilé métallique 4 en U supérieur ou inférieur correspondant en venant en appui contre le fond 42 de ce dernier et, d'autre part, par deux profilés métallique 4 en U formant ses deux côtés opposés horizontaux supérieur et inférieur et pouvant être disposés entre les deux côtés opposés horizontaux supérieur et inférieur du cadre externe (notamment figures 2 et 3).  In a preferred embodiment of the inner frame, in the mounted state in a vertical plane, it may consist, on the one hand, by two metal profiles 4 C forming its two opposite sides vertical, the ends of said profiles 4 metal C in each of which can be inserted between the two flanges 41 of the upper or lower U-shaped metal profile 4 corresponding by bearing against the bottom 42 of the latter and, on the other hand, by two U-shaped metal sections 4 forming its two opposite horizontal upper and lower sides and being able to be arranged between the two opposite horizontal sides upper and lower of the outer frame (in particular Figures 2 and 3).
De préférence, chaque profilé métallique 4 en U horizontal du cadre interne peut être fixé par ses extrémités sur les deux profilés métalliques 5 en C verticaux et chaque profilé métallique 4, 5 en U et en C du cadre interne peut être orienté de sorte que l'ouverture du U ou du C puisse se trouver à l'extérieur du cadre interne afin de former une surface d'appui, constituée par le dos de chaque profilé, pour la réception du bloc- porte.  Preferably, each horizontal U-shaped metal section 4 of the internal frame can be fixed at its ends to the two vertical C-shaped metal sections 5 and each U-shaped and C-shaped metal section 4 of the internal frame can be oriented so that the opening of the U or C can be outside the internal frame to form a bearing surface formed by the back of each section, for receiving the door block.
Les profilés métalliques 5 en C du cadre externe et du cadre interne peuvent être assemblés fixement aux profilés métalliques 4 en U du cadre externe au moyen de liaisons rigides tels que des vis.  The metal profiles 5 C of the outer frame and the inner frame can be fixedly assembled to the U-shaped metal sections 4 of the outer frame by means of rigid connections such as screws.
D'autre part, les profilés métalliques 4 en U horizontaux du cadre interne peuvent être fixés aux profilés métalliques 5 en C verticaux de ce dernier soit par soudage, soit par l'intermédiaire d'un assemblage mécanique comprenant une équerre métallique.  On the other hand, the horizontal U-shaped metal sections 4 of the inner frame can be fixed to the vertical C-shaped metal sections 5 of the latter either by welding or by means of a mechanical assembly comprising a metal bracket.
Le profilé métallique 4 en U inférieur du cadre interne peut être avantageusement renforcé par un profilé métallique 5 en C reliant perpendiculairement ledit profilé métallique 4 en U inférieur au profilé métallique 5 en C inférieur du cadre externe.  The lower U-shaped metal section 4 of the inner frame may advantageously be reinforced by a C-shaped metal section 5 perpendicularly connecting said lower U-shaped metal section 4 to the lower C-shaped metal section 5 of the outer frame.
On comprendra que selon l'invention les profilés métalliques 4, 5 en U et en C peuvent de dimensions différentes, notamment de longueurs différentes selon notamment qu'ils servent à la formation les côtés verticaux et horizontaux des cadres interne et externe ou au renfort de l'ossature, un renfort vertical seulement étant représenté sur les figures 2, 3 et 4. Dans une forme préférentielle de chaque panneau 6 coupe-feu, celui-ci peut comprendre une superposition de deux couches, dont l'une peut être constituée de préférence par une plaque coupe feu 6a et l'autre peut être constituée de préférence par une feuille d'acier 6b. En outre, la feuille d'acier 6b peut être fixée préférentiellement à la plaque coupe-feu par collage (figures 1, 4, 5, 6). It will be understood that, according to the invention, the metal sections 4, 5 in U and in C may have different dimensions, in particular of different lengths depending in particular that they serve for forming the vertical and horizontal sides of the inner and outer frames or the reinforcement of the frame, a vertical reinforcement only being shown in Figures 2, 3 and 4. In a preferred form of each firewall panel 6, it may comprise a superposition of two layers, one of which may be preferably constituted by a fire-resistant plate 6a and the other may preferably consist of a sheet of steel 6b. In addition, the steel sheet 6b may be preferably fixed to the firestop plate by gluing (FIGS. 1, 4, 5, 6).
Bien entendu, et en fonction du requis ou de la durée de tenue au feu de la cloison 1, l'épaisseur de chaque panneau coupe feu 6 peut être modifiée en conséquence.  Of course, and depending on the required fire resistance or duration of the partition 1, the thickness of each fireproof panel 6 can be modified accordingly.
La feuille d'acier 6b de chaque panneau a pour rôle : The steel sheet 6b of each panel has for role:
- de protéger le panneau coupe feu en cas d'agression extérieure comme des impacts de chariots, - to protect the fireproof panel in case of external aggression, such as the impacts of trolleys,
- de permettre de rendre la cloison décontaminable car la surface peut être lisse et non poreuse,  allow the partition to be decontaminated because the surface can be smooth and non-porous,
- d'augmenter les caractéristiques mécaniques des panneaux coupe feu et ainsi garantir une tenue au feu après séisme.  - to increase the mechanical characteristics of fireproof panels and thus guarantee a fire resistance after earthquake.
Chaque panneau 6 peut être maintenu fixement contre l'ossature 4, 5 au moyen de vis 6c.  Each panel 6 can be fixedly held against the frame 4, 5 by means of screws 6c.
Ainsi, dans la présente invention, le dispositif de cloison murale peut être constitué au minimum, d'une part, par quatre profilés métalliques 5 en C verticaux, à savoir deux profilés en C pour créer l'ouverture 2 du bloc-porte ou de la porte, et deux profilés en C pour créer les extrémités latérales de la cloison 1 et, d'autre part, par quatre profilés métalliques 4 en U horizontaux, à savoir deux profilés en U pour délimiter en haut et en bas l'ouverture 2 recevant le bloc-porte et deux profilés en U pour créer les extrémités haute et basse de la cloison 1.  Thus, in the present invention, the wall partition device may consist at least, on the one hand, of four vertical C-shaped metal profiles, namely two C-sections to create the opening 2 of the door block or the door, and two C-sections to create the lateral ends of the partition 1 and, secondly, by four horizontal U-shaped metal sections, namely two U-shaped profiles to delimit at the top and bottom the opening 2 receiving the door block and two U-shaped profiles to create the high and low ends of the partition 1.
Les extrémités haute et basse de la cloison 1 , notamment de l'ossatuire 4, 5, peuvent être fixées respectivement sur un sol ou un plafond, par exemple par chevillage dans le cas où le sol et le plafond sont en béton, ou sur des linteaux haut et bas 7, par exemple de section transversale en I, comme on peut le voir sur les figures 2, 3, 4, 5.  The high and low ends of the partition 1, in particular the ossatuire 4, 5, can be fixed respectively on a floor or a ceiling, for example by pegging in the case where the floor and the ceiling are concrete, or on lintels up and down 7, for example cross-section I, as can be seen in Figures 2, 3, 4, 5.
On notera que la présente invention peut prévoir des profilés métalliques en U ou en C supplémentaires pour augmenter les caractéristiques mécaniques de la structure si une demande particulière est requise comme par exemple une tenue à un séisme, à une surpression ou à une hauteur d'eau. La présente invention a également pour objet un ensemble de cloison murale 1 avec bloc-porte 3 comprenant une structure de cloison murale et un bloc-porte 3 coupe feu et/ou étanche aux fumées comportant un cadre dormant 3 a et un ouvrant 3b. Note that the present invention may provide additional U or C metal profiles to increase the mechanical characteristics of the structure if a particular request is required such as for example a resistance to an earthquake, an overpressure or a water level . The present invention also relates to a set of wall partition 1 with door block 3 comprising a wall partition structure and a fireproof and / or smokeproof door block 3 comprising a frame 3 and a sash opening 3b.
Un tel bloc-porte 3 peut par exemple être du type de celui décrit dans la demande de brevet WO 2011/154619.  Such a door block 3 may for example be of the type described in patent application WO 2011/154619.
Conformément à la présente invention, dans un tel ensemble, la structure de cloison murale consiste en un dispositif de cloison murale tel que défini selon la présente invention ci-dessus.  According to the present invention, in such an assembly, the wall partition structure consists of a wall partition device as defined according to the present invention above.
Dans un tel ensemble le cadre dormant 3a peut consister en une tôle pliée 8 fixée sur l'ossature 4, 5 métallique de la cloison 1, au moyen de liaison rigides telles que des vis, de sorte à permettre la liaison entre le bloc- porte 3 et la cloison murale 1 dudit dispositif (figure 6 notamment). En outre, le cadre dormant 3b peut présenter un retour pour réaliser l'arrêt du bloc-porte 3. Pars ailleurs, une isolation 9a, 9b peut être prévue dans le cadre dormant 3a et l'ossature 4, 5 pour empêcher la déformation de cette dernière lors d'un incendie (figure 6).  In such an assembly the fixed frame 3a may consist of a folded sheet 8 fixed on the metal frame 4, 5 of the partition 1, by rigid connection means such as screws, so as to allow the connection between the door block 3 and the wall partition 1 of said device (Figure 6 in particular). In addition, the fixed frame 3b may have a return to perform the stop of the door block 3. Moreover, an insulation 9a, 9b may be provided in the frame 3a and the frame 4, 5 to prevent deformation of the latter during a fire (Figure 6).
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
