Description

DISPOSITIF COUPE-FEU FIRE PROTECTION DEVICE
La présente invention a trait à un dispositif coupe-feu pour le calfeutrement d'une ouverture, d'une part, définie au niveau d'un élément de séparation sous forme d'une cloison, d'un mur ou analogue, et, d'autre part, traversée par des éléments traversants, notamment constitués par des câbles, des conduites ou analogue.The present invention relates to a firestop device for caulking an opening, on the one hand, defined at the level of a separating element in the form of a partition, a wall or the like, and, d on the other hand, traversed by through elements, in particular constituted by cables, pipes or the like.
La présente invention concerne le domaine de la fabrication des dispositifs conçus aptes à éviter la propagation des flammes et/ou des fumées d'un incendie d'un local à un autre, ceci au travers d'une ouverture définie au niveau d'un mur ou d'une cloison séparant les deux locaux et autorisant le passage de câbles, conduits ou analogues. L'on connaît, d'ores et déjà, un dispositif coupe-feu illustré dans le document WO03095757 et qui est composé, d'une part, d'un cadre interne destiné à être monté à l'intérieur d'une ouverture définie dans un mur et comportant une pluralité de compartiments conçus, chacun, aptes à être traversés par un ou plusieurs câbles ou analogue et, d'autre part, d'un cadre externe, associé à ce cadre interne, venant se positionner à l'avant de ce dernier et en saillie par rapport au mur. Ce cadre externe comporte plusieurs côtés assemblés de manière réversible autour des câbles ou analogue et est rendu solidaire du cadre interne ou du mur.The present invention relates to the field of manufacturing devices designed to prevent the spread of flames and / or smoke from a fire from one room to another, this through an opening defined at a wall or a partition separating the two premises and allowing the passage of cables, conduits or the like. There is already known a firestop device shown in WO03095757 and which is composed, on the one hand, of an internal frame intended to be mounted inside an opening defined in FIG. a wall and having a plurality of compartments each designed to be traversed by one or more cables or the like and, on the other hand, an external frame, associated with this internal frame, coming to be positioned in front of the the latter and protruding from the wall. This outer frame has several sides reversibly assembled around the cables or the like and is secured to the inner frame or wall.
Ce dispositif présente un certain nombre d'inconvénients consistant, notamment, en ce que le cadre interne doit présenter des dimensions autorisant son implantation à l'intérieur d'une ouverture que comporte le mur tout en assurant, de manière efficace, une fonction de coupe-feu en cas d'incendie.This device has a certain number of disadvantages consisting, in particular, in that the internal frame must have dimensions allowing its implantation inside an opening that the wall comprises while ensuring, in an effective manner, a cutting function. -fire in case of fire.
Afin de réaliser une telle implantation, il est, alors, indispensable que ce cadre interne présente des dimensions sensiblement ajustées à celles de ladite ouverture ce qui implique la fabrication, l'achat et l'acheminement sur site d'une pluralité de dispositifs de dimensions différentes. De plus et afin d'assurer la fonction coupe-feu, il est, de surcroît:, indispensable de combler un interstice subsistant entre ce cadre interne et les parois de l'ouverture, notamment par maçonnage.In order to achieve such an implementation, it is then essential that this internal frame has dimensions substantially adjusted to those of said opening which involves the manufacture, purchase and on-site routing of a plurality of devices dimensions different. Moreover and in order to ensure the fire-stop function, it is, of In addition, it is essential to fill a gap that exists between this internal frame and the walls of the opening, particularly by brickwork.
Une autre solution consiste à choisir, soit un cadre aux dimensions inférieures à celles de l'ouverture et de procéder à un maçonnage autour dudit cadre, soit un cadre interne aux dimensions supérieures à celles de l'ouverture et à intervenir sur la maçonnerie afin d'élargir cette ouverture, voire encore de maçonner autour du cadre après son implantation. Quelle que soit la situation, ceci se traduit par une multiplication des dispositifs nécessaires et/ou par un certain nombre d'opérations manuelles additionnelles fastidieuses et coûteuses.Another solution is to choose either a frame with dimensions smaller than those of the opening and to proceed with a masonry around said frame, an internal frame with dimensions greater than those of the opening and to intervene on the masonry to 'widen this opening, or even to build around the frame after its implementation. Whatever the situation, this results in a multiplication of the necessary devices and / or by a number of additional manual operations tedious and expensive.
Un autre inconvénient consiste en ce que ce dispositif, plus particulièrement son cadre interne, doit impérativement être implanté au niveau de la maçonnerie avant la mise en place des câbles ou analogues qui sont amenés à traverser les compartiments définis au niveau de ce cadre. Ce dispositif ne convient, alors, aucunement, lorsqu'il s'agit de calfeutrer une ouverture d'ores et déjà traversée par de tels câbles ou analogues, par exemple dans le cadre de la rénovation ou de la sécurisation d'une installation existante.Another disadvantage is that this device, more particularly its internal frame, must imperatively be implanted at the masonry before the introduction of cables or the like which are caused to pass through the compartments defined at this frame. This device is suitable, then, in any way, when it comes to caulking an opening already traversed by such cables or the like, for example in the context of the renovation or securing of an existing installation.
Encore un autre inconvénient consiste en ce que, d'une part, les câbles ou analogues traversent des compartiments mettant en communication les deux locaux et, d'autre part, le cadre externe comporte des moyens expansables uniquement à haute température et aptes à obturer l'ouverture de ce cadre externe uniquement en cas d'incendie, de sorte qu'à froid, une circulation d'air, de fumées ou de poussières est toujours permise au travers de ce dispositif. Finalement, ce dispositif est conçu en sorte que, lorsque le cadre externe est un élément séparé du cadre interne, la solidarisation de ces cadres est réalisée par soudure, rivetage ou collage ce qui exclut tout démontage et toute intervention sur ce dispositif après son implantation sur site. L'on connaît, encore, un dispositif, décrit dans le document GB-2.334.770, et adoptant la forme d'un collier destiné à entourer un tube. Ce collier est constitué de deux parties articulées l'une par rapport à l'autre et est revêtu, intérieurement, par un matériau intumescent conçu pour, en cas de feu, gonfler et remplir l'espace entre le tube et ce collier. Ce dispositif permet, alors, de constituer une barrière uniquement lorsque le feu est déjà bien déclaré et que les flammes aient atteint ce dispositif ou que le local, au niveau duquel est implanté ce dispositif, ait atteint une température particulièrement élevée. La présente invention se veut à même de remédier aux inconvénients des dispositifs de l'état de la technique au travers d'un nouveau dispositif coupe-feu.Yet another disadvantage is that, on the one hand, the cables or the like pass through compartments communicating the two premises and, on the other hand, the outer frame includes expansible means only at high temperature and able to close the door. opening of this external frame only in case of fire, so that cold air circulation, fumes or dust is still allowed through this device. Finally, this device is designed so that, when the external frame is a separate element of the internal frame, the joining of these frames is performed by welding, riveting or gluing which excludes any disassembly and any intervention on this device after its implementation on site. There is still known a device, described in document GB-2 334.770, and adopting the shape of a collar intended to surround a tube. This collar consists of two parts hinged to each other and is coated internally by an intumescent material designed to, in case of fire, inflate and fill the space between the tube and the collar. This device then makes it possible to constitute a barrier only when the fire is already well declared and that the flames have reached this device or that the local, at which the device is implanted, has reached a particularly high temperature. The present invention is intended to overcome the disadvantages of devices of the state of the art through a new firewall device.
A cet effet, l'invention concerne un dispositif coupe-feu pour le calfeutrement d'une ouverture, d'une part, définie au niveau d'un élément de séparation sous forme d'une cloison, d'un mur ou analogue, et, d'autre part, traversée par des éléments traversants, notamment constitués par des câbles, des conduites ou analogue, ce dispositif adoptant la forme d'un corps tubulaire présentant deux extrémités au niveau desquelles ce corps tubulaire présente une ouverture destinée à être traversée par lesdits éléments traversants qui s'étendent à l'intérieur dudit corps tubulaire constitué de deux portions de tube de forme complémentaire, d'une part, assemblées par le biais de moyens d'assemblage que comporte ledit dispositif, s'étendant d'une ouverture à l'autre et le long dudit corps tubulaire, et, d'autre part, immobilisées, notamment de manière réversible, l'une par rapport à l'autre par le biais de moyens d'immobilisation que comporte le dispositif. Ce dispositif est caractérisé par le fait qu'il comporte, intérieurement, des moyens conçus aptes à empêcher la traversée de ce dispositif par des particules contenues dans un flux d'air, voire par un tel flux d'air, ceci au moins pour une température inférieure à celle d'un incendie.To this end, the invention relates to a fireproof device for sealing an opening, on the one hand, defined at the level of a separating element in the form of a partition, a wall or the like, and on the other hand, traversed by through elements, in particular constituted by cables, pipes or the like, this device adopting the shape of a tubular body having two ends at which this tubular body has an opening intended to be traversed by said through elements which extend inside said tubular body consisting of two complementary shaped tube portions, on the one hand, assembled by means of assembly means which comprises said device, extending from an opening to the other and along said tubular body, and, secondly, immobilized, particularly reversibly, relative to each other through means of immobilization that includes the device.

Selon une autre caractéristique de l'invention, les moyens d'assemblage sont constitués, d'une part, par des moyens d'emboîtement que comporte l'une des portions de tube et, d'autre part, par des moyens d'emboîtement complémentaires que comporte l'autre portion de tube et conçus aptes à coopérer avec lesdits moyens d'emboîtement.According to another characteristic of the invention, the assembly means are constituted, on the one hand, by interlocking means that comprises one of the tube portions and, on the other hand, by complementary engagement means that includes the other tube portion and designed adapted to cooperate with said interlocking means.
Une caractéristique additionnelle consiste en ce que les moyens d'immobilisation sont de type réversible et sont définis par des moyens de type amovible aptes à rendre solidaires, de manière réversible, les deux portions de tube au niveau desdits moyens d'assemblage que comporte ce tube.An additional feature is that the immobilizing means are of the reversible type and are defined by means of removable type capable of reversibly securing the two tube portions at the level of said assembly means that this tube comprises. .
Une autre caractéristique additionnelle consiste en ce que les moyens d'immobilisation sont de type réversible et sont définis, d'une part, par des moyens d'accrochage que comporte l'une des portions de tube et, d'autre part, par des moyens d'accrochage complémentaires que comporte l'autre portion de tube et conçus aptes à coopérer, de manière réversible, avec lesdits moyens d'accrochage.Another additional feature consists in that the immobilization means are of the reversible type and are defined, on the one hand, by hooking means that comprise one of the tube portions and, on the other hand, by means complementary hooking means that comprises the other portion of tube and designed adapted to cooperate, reversibly, with said hooking means.
Encore une autre caractéristique concerne des moyens d'immobilisation de type réversible et constitués par une grenouillère comportant, d'une part, une première partie rendue solidaire d'une portion de tube et, d'autre part, une seconde partie rendue solidaire de l'autre portion de ce tube et conçue apte à coopérer avec ladite première partie en vue de l'immobilisation de ces portions de tube, l'une par rapport à l'autre.Yet another characteristic relates to immobilization means of the reversible type constituted by a toggle device comprising, firstly, a first portion secured to a portion of a tube and, secondly, a second portion secured to the another portion of this tube and designed adapted to cooperate with said first portion for the immobilization of these tube portions, relative to each other.
Selon une autre caractéristique de l'invention, les moyens d'immobilisation réversible sont complétés par des moyens conçus aptes à indiquer et/ou à empêcher une intervention sur ces moyens d'immobilisation après assemblage et immobilisation des deux portions de tube.According to another characteristic of the invention, the reversible immobilization means are completed by means designed to indicate and / or prevent intervention on these immobilization means after assembly and immobilization of the two tube portions.
Une caractéristique additionnelle concerne le fait que le dispositif comporte, intérieurement, des moyens aptes à empêcher une circulation d'air au travers de ce dispositif, ceci au moins en cas d'incendie, plus particulièrement pour une température correspondant à celle d'un incendie.An additional feature relates to the fact that the device comprises, internally, means adapted to prevent air circulation through this device, this at least in case of fire, especially for a temperature corresponding to that of a fire .
Finalement, ce dispositif comporte des moyens conçus aptes à assurer une protection des moyens pour empêcher sa traversée par des particules ou par un flux d'air, ces moyens de protection étant conçus aptes à assurer une telle protection en cas d'augmentation de la température, notamment en cas d'incendie.Finally, this device comprises means designed to provide protection means to prevent its passage through particles or by a flow of air, these means of protection being designed to provide such protection in the event of an increase in temperature, particularly in case of fire.
Les avantages de la présente invention consistent en ce que le dispositif peut être implanté par-dessus des câbles, conduites ou autres alors que ceux-ci sont d'ores et déjà en place au niveau de l'ouverture.The advantages of the present invention are that the device can be implanted over cables, pipes or other, while these are already in place at the opening.
Ce dispositif peut, également, être implanté au niveau d'une ouverture qui se situe à proximité immédiate du plafond, notamment par engagement d'une portion de tube par-dessus les éléments traversants et par coulissement par-dessus ces derniers et en direction de l'élément de séparation.This device can also be implanted at an opening which is in the immediate vicinity of the ceiling, in particular by engaging a portion of tube over the through elements and by sliding over them and in the direction of the separating element.
Encore un autre avantage consiste en ce que les portions de tube de ce dispositif sont immobilisées par le biais de moyens de type réversible complétés par des moyens conçus aptes à indiquer et/ou à empêcher une intervention sur ces moyens d'immobilisation, ceci après assemblage et immobilisation des deux portions de tube. La présence de ces moyens d'indication et/ou d'empêchement, soit permet de garantir l'inviolabilité du dispositif, soit autorise uniquement l'intervention d'un personnel habilité, soit permet de garantir le comportement approprié du dispositif vis-à-vis d'un incendie.Yet another advantage is that the tube portions of this device are immobilized by means of reversible type of means completed by means designed to indicate and / or prevent intervention on these immobilization means, this after assembly and immobilizing the two tube portions. The presence of these means of indication and / or prevention, either ensures the inviolability of the device, or allows only the intervention of authorized personnel, or ensures the appropriate behavior of the device vis-à- fire.
Un autre avantage concerne la possibilité de faire traverser le dispositif par de nouveaux éléments traversants, même après implantation sur site du dispositif, ceci sans procéder au démontage de ce dernier et tout en garantissant un comportement approprié en cas d'incendie.Another advantage relates to the possibility of passing through the device with new through elements, even after implantation on site of the device, this without disassembly of the latter and while ensuring appropriate behavior in case of fire.
Selon un autre avantage, le dispositif permet d'empêcher une circulation de particules, voire d'air, entre deux locaux et au travers de ce dispositif, ceci même à froid lorsqu'aucun incendie n'est déclaré.According to another advantage, the device makes it possible to prevent particle or even air circulation between two premises and through this device, even in the cold when no fire is declared.
Encore un autre avantage consiste en ce que ce dispositif vient en applique contre la paroi d'un élément de séparation et peut être maintenu en applique, soit en rendant le dispositif solidaire de l'élément de séparation, soit par simple fermeture du dispositif sur les éléments traversants et par serrage sur ces derniers. Ce dispositif n'est aucunement destiné à être implanté à l'intérieur d'une ouverture et, par conséquent, ne nécessite aucune intervention (reprise, maçonnage) sur ledit élément de séparation ou sur l'ouverture y ménagée. D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation qui ne sont donnés qu'à titre d'exemples indicatifs et non limitatifs.Yet another advantage is that this device comes into application against the wall of a separating element and can be maintained in applied manner, either by making the device integral with the separating element, or by simply closing the device on the through elements and by clamping on these latter. This device is not intended to be implanted inside an opening and, therefore, requires no intervention (recovery, masonry) on said separation element or on the opening therein. Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

La présente invention concerne le domaine de la fabrication des dispositifs conçus aptes à éviter la propagation des flammes et/ou des fumées d'un incendie d'un local à un autre, ceci au travers d'une ouverture, d'une part, définie au niveau d'un élément de séparation 1 adoptant la forme d'un mur ou d'une cloison séparant les deux locaux et, d'autre part, autorisant le passage d'éléments traversants 2 adoptant la forme de câbles (notamment électriques) , de conduits (notamment de circulation d'un fluide) ou analogues, ceci au travers dudit élément de séparation 1 et d'un local à l'autre.The present invention relates to the field of manufacturing devices designed to prevent the propagation of flames and / or fumes from a fire from one room to another, through an opening, on the one hand, defined at the level of a separating element 1 adopting the form of a wall or partition separating the two premises and, secondly, allowing the passage of through elements 2 adopting the form of cables (especially electrical), conduits (in particular of circulation of a fluid) or the like, this through said separating element 1 and from one room to another.
En fait, l'invention a trait à un dispositif 3 coupe-feu pour le calfeutrement d'une telle ouverture, ce dispositif 3 adoptant la forme d'un corps tubulaire 4 présentant deux extrémités 5 ; 6 au niveau desquelles ce corps tubulaire 4 présente une ouverture 7 ; 8. Ces ouvertures 7 ; 8 sont destinées à être traversées par des éléments traversants 2 qui s'étendent à l'intérieur dudit corps tubulaire 4. Selon l'invention, ce corps tubulaire 4 est constitué de deux portions 9 ; 10 de tube 4 de forme complémentaire, de préférence réalisées en un matériau résistant au feu, plus particulièrement de la tôle, notamment galvanisée.In fact, the invention relates to a device 3 firewall for caulking such an opening, this device 3 adopting the shape of a tubular body 4 having two ends 5; 6 at which this tubular body 4 has an opening 7; 8. These openings 7; 8 are intended to be traversed by through elements 2 which extend inside said tubular body 4. According to the invention, this tubular body 4 consists of two portions 9; 10 of tube 4 of complementary shape, of preferably made of a fire-resistant material, more particularly the sheet, in particular galvanized.
A ce propos, on observera qu'au moins une portion 9 du tubeIn this regard, it will be observed that at least a portion 9 of the tube
4 constituant, en partie, ledit corps tubulaire 4, est définie par un profilé en « U » 11 comportant deux ailes 12 ; 13, sensiblement parallèles, et raccordées entre elles par une partie intermédiaire 14.4 constituting, in part, said tubular body 4, is defined by a profile "U" 11 having two wings 12; 13, substantially parallel, and interconnected by an intermediate portion 14.
En ce qui concerne l'autre portion 10 du tube 4, celle-ci peut, là encore, être définie par un profilé en « U ». Cependant et selon un mode de réalisation préféré de l'invention illustré sur les figures en annexe, cette autre portion de tube 10 est définie par un profilé plan 15.Regarding the other portion 10 of the tube 4, it can, again, be defined by a section "U". However, and according to a preferred embodiment of the invention illustrated in the appended figures, this other portion of tube 10 is defined by a planar profile 15.
Selon une autre caractéristique de l'invention, les deux portions 9 ; 10 de tube 4 sont assemblées par le biais de moyens d'assemblage 16 que comporte ledit dispositif 3 et qui s'étendent d'une ouverture 8 à l'autre 9, ceci le long dudit corps tubulaire 4.According to another characteristic of the invention, the two portions 9; 10 of tube 4 are assembled by means of assembly means 16 that comprises said device 3 and which extend from an opening 8 to the other 9, this along said tubular body 4.
Tel que visible sur les figures en annexe, lesdits moyens d'assemblage 16 sont constitués, d'une part, par des moyens d'emboîtement 17 que comporte l'une 9 des portions de tube 4 et, d'autre part, par des moyens d'emboîtement complémentaires 18 que comporte l'autre portion 10 de tube 4 et conçus aptes à coopérer avec lesdits moyens d'emboîtement 17.As can be seen in the appended figures, said assembly means 16 are constituted, on the one hand, by interlocking means 17 that comprise one of the tube portions 4 and, on the other hand, by complementary interlocking means 18 provided by the other portion 10 of tube 4 and designed to cooperate with said interlocking means 17.
Tel que visible sur la figure 1, les moyens d'emboîtement 17 sont définis au niveau du bord libre des ailes 12 ; 13 du profilé en « U » 11 constituant une portion 9 de tube 4 tandis que les moyens d'emboîtement complémentaires 18 sont définis au niveau de rebords latéraux 19 définis, notamment, au niveau du profilé plan 15 constituant l'autre portion 10 de tube 4. Selon une caractéristique additionnelle de l'invention, les deux portions 9 ; 10 de tube 4 sont immobilisées l'une 9 par rapport à l'autre 10 par le biais de moyens d'immobilisation 20 que comporte le dispositif 3, plus particulièrement à proximité ou au niveau desdits moyens d'assemblage 16 susmentionnés. Selon un premier type de réalisation, lesdits moyens d'immobilisation 20 sont conçus aptes à assurer une immobilisation définitive des deux portions 9 ; 10 de tube 4 l'une 9 par rapport à l'autre 10.As shown in Figure 1, the interlocking means 17 are defined at the free edge of the wings 12; 13 of the profile "U" 11 constituting a portion 9 of tube 4 while the complementary engagement means 18 are defined at the side edges 19 defined, in particular, at the level of the profile 15 constituting the other portion 10 tube 4. According to an additional feature of the invention, the two portions 9; 10 of tube 4 are immobilized one with respect to the other 10 by means of immobilization means 20 which comprises the device 3, more particularly near or at the level of said connecting means 16 mentioned above. According to a first embodiment, said immobilizing means 20 are designed to ensure a final immobilization of the two portions 9; 10 of tube 4 one 9 relative to the other 10.
Cependant et selon un type de réalisation préféré de l'invention, ces moyens d'immobilisation 20 sont conçus aptes à assurer une immobilisation réversible des deux portions 9 ; 10 de tube 4 l'une 9 par rapport à l'autre 10.However, and according to a preferred embodiment of the invention, these immobilizing means 20 are designed capable of reversibly immobilizing the two portions 9; 10 of tube 4 one 9 relative to the other 10.
Selon un premier mode de réalisation, les moyens 20 d'immobilisation réversible sont définis par des moyens de type amovible et sont conçus aptes à rendre solidaires, de manière réversible, les deux portions 9 ; 10 de tube 4 au niveau desdits moyens d'assemblage 16 que comporte ce tube 4.According to a first embodiment, the reversible immobilization means 20 are defined by means of removable type and are designed able to reversibly join the two portions 9; 10 of tube 4 at said assembly means 16 that includes this tube 4.
De tels moyens d'immobilisation 20 amovibles peuvent être constitués par une tige amovible 21 (figure 1) ou par des portions de tige amovibles (non représentées) aptes à coopérer avec des orifices 22 que comportent en correspondance les deux portions 9 ; 10 de tube 4 au niveau des moyens d'assemblage 16.Such removable immobilizing means 20 may be constituted by a removable rod 21 (FIG. 1) or by removable rod portions (not shown) capable of cooperating with orifices 22 correspondingly comprising the two portions 9; 10 of tube 4 at the level of the assembly means 16.
Un autre mode de réalisation consiste en des moyens 20 d'immobilisation réversible définis, d'une part, par des moyens d'accrochage que comporte l'une 9 des portions de tube 4 et, d'autre part, par des moyens d'accrochage complémentaires que comporte l'autre 10 portion de tube 4 et conçus aptes à coopérer avec lesdits moyens d'accrochage.Another embodiment consists of reversible immobilization means defined, on the one hand, by hooking means which comprises a 9 of tube portions 4 and, on the other hand, by means of complementary hooking that comprises the other portion of tube 4 and designed adapted to cooperate with said hooking means.
Là encore, de tels moyens d'accrochage et de tels moyens d'accrochage complémentaires peuvent être définis au niveau des moyens d'assemblage 16 que comporte le tube 4.Again, such hooking means and such additional hooking means can be defined at the level of the assembly means 16 that includes the tube 4.
Un mode de réalisation préféré concerne, alors, des moyens d'accrochage constitués par des moyens d'endiquetage aptes à coopérer avec des moyens d'endiquetage complémentaires constituant des moyens d'accrochage complémentaires. Cependant et selon un mode de réalisation préféré de l'invention, les moyens 20 d'immobilisation réversible sont constitués par une grenouillère comportant, d'une part, une première partie rendue solidaire d'une portion 9 ; 10 de tube 4 et, d'autre part, une seconde partie rendue solidaire de l'autre portion 10 ; 9 de ce tube 4 et conçue apte à coopérer avec ladite première partie en vue de l'immobilisation de ces portions 9 ; 10 de tube 4, l'une 9 par rapport à l'autre 10.A preferred embodiment relates, then, hooking means constituted by means of coupling capable of cooperating with complementary coupling means constituting complementary attachment means. However, and according to a preferred embodiment of the invention, the reversible immobilization means 20 are constituted by a toggle device comprising, on the one hand, a first portion secured to a portion 9; 10 of tube 4 and, secondly, a second portion secured to the other portion 10; 9 of this tube 4 and designed able to cooperate with said first portion for the immobilization of these portions 9; 10 of tube 4, one 9 relative to the other 10.
A ce propos, on observera que les moyens 20 agencés pour assurer une immobilisation réversible peuvent, avantageusement, être complétés par des moyens conçus aptes à indiquer et/ou à empêcher une intervention sur ces moyens d'immobilisation 20 après assemblage et immobilisation des deux portions 9 ; 10 de tube 4.In this regard, it will be observed that the means 20 arranged to ensure reversible immobilization can advantageously be supplemented by means designed to indicate and / or prevent intervention on these immobilization means 20 after assembly and immobilization of the two portions. 9; 10 of tube 4.
De tels moyens d'indication et/ou d'empêchement peuvent être constitués par un scellé ou analogue.Such means of indication and / or prevention may be constituted by a seal or the like.
Ces moyens peuvent, alors, être mise en place par un installateur agréé garantissant le montage approprié du dispositif 3 et le bon comportement de ce dernier 3, notamment vis-à-vis d'un incendie. L'absence ou la détérioration de ces moyens indique une intervention non autorisée sur le dispositif 3.These means can then be set up by an authorized installer to ensure the proper mounting of the device 3 and the good behavior of the latter 3, especially vis-à-vis a fire. The absence or the deterioration of these means indicates an unauthorized intervention on the device 3.
Selon une autre caractéristique de l'invention, l'une 10 des portions de tube 4 définit un support pour la réception desdits éléments traversants 2 qui peuvent, alors, venir reposer (directement ou indirectement) sur un tel support, notamment défini par le profilé plan 15.According to another characteristic of the invention, one of the tube portions 4 defines a support for the reception of said through elements 2 which can then come to rest (directly or indirectly) on such a support, in particular defined by the profile plan 15.
Une telle portion 10 de tube 4 peut, encore, définir un support pour la réception d'un moyen de montage de ces éléments traversants 2 sur cette portion 10 de tube 4 et, ainsi, dans le dispositif 3.Such a portion 10 of tube 4 may, again, define a support for receiving a means for mounting these through elements 2 on this portion 10 of tube 4 and, thus, in the device 3.
A ce propos, on observera qu'un tel moyen de montage peut être constitué par un chemin de câble 23 illustré figure 2, par des pattes de fixation d'un ou plusieurs éléments traversants 2 ou analogue. Une telle portion 10 de tube 4 constitue, alors, un support tandis que l'autre portion 9 de tube 4 définit un capot conçu apte à venir se positionner (notamment de manière amovible) par¬ dessus ledit support.In this respect, it will be observed that such a mounting means may consist of a cable duct 23 illustrated in FIG. 2, by fixing tabs of one or more through-members 2 or the like. Such a portion 10 of tube 4 constitutes, then, a support while the other portion 9 of tube 4 defines a hood designed to be positioned (including removably) over said support.
Ainsi et tel que visible sur les figures en annexe, le dispositif 3 adopte, de préférence, la forme d'un boîtier ouvert comportant, d'une part, un tel support constituant le fond du boîtier et, d'autre part, un tel capot constituant le couvercle de ce boîtier.Thus, and as can be seen in the appended figures, the device 3 preferably adopts the shape of an open housing comprising, on the one hand, such a support constituting the bottom of the housing and, secondly, such a cover constituting the cover of this housing.
Selon un premier mode de réalisation, le dispositif 3 selon l'invention peut être conçu apte à être resserré par-dessus et/ou autour des éléments traversants 2, ceci par le biais des moyens d'assemblage 16 et des moyens d'immobilisation 20. Un tel mode de réalisation autorise un positionnement dudit dispositif 3 à proximité de l'ouverture définie au niveau de l'élément de séparation 1 sans que ce dispositif 3 ne soit rendu solidaire de ce dernier 1.According to a first embodiment, the device 3 according to the invention can be designed adapted to be tightened over and / or around the through elements 2, this through the assembly means 16 and the immobilizing means 20 Such an embodiment allows positioning of said device 3 near the opening defined at the level of the separating element 1 without this device 3 being made integral with the latter 1.
Cependant et selon un autre mode de réalisation, l'une au moins des portions 9 ; 10 de tube 4 comporte ou est conçue apte à coopérer avec des moyens de fixation du dispositif 3 sur ledit élément de séparation 1 pourvu de ladite ouverture, notamment en périphérie de cette dernière.However, according to another embodiment, at least one of the portions 9; 10 of tube 4 comprises or is designed capable of cooperating with means for fixing the device 3 on said separating element 1 provided with said opening, in particular at the periphery of the latter.
Un mode préféré de réalisation consiste en ce que seule la portion 10 de tube 4 définissant le support comporte ou est conçue apte à coopérer avec de tels moyens de fixation, usuellement définis par des vis ou analogue. Selon une autre caractéristique de l'invention, le dispositif 3 comporte, intérieurement, des moyens 24 aptes à empêcher une circulation d'air au travers de ce dispositif 3, ceci au moins en cas d'incendie, plus particulièrement pour une température correspondant à celle d'un incendie. Pour ce faire, de tels moyens 24 peuvent être constitués par un habillage 25, 25' d'au moins une paroi interne d'au moins une portion 10 ; 9 de tube 4 par un matériau intumescent.A preferred embodiment consists in that only the tube portion 4 defining the support comprises or is designed capable of cooperating with such fixing means, usually defined by screws or the like. According to another characteristic of the invention, the device 3 comprises, internally, means 24 adapted to prevent a flow of air through the device 3, this at least in case of fire, more particularly for a temperature corresponding to that of a fire. To do this, such means 24 may consist of a covering 25, 25 'of at least one inner wall of at least a portion 10; 9 of tube 4 by an intumescent material.
En fait, un tel habillage 25, 25' est disposé sur une partie au moins du pourtour interne dudit dispositif 3 mais est, de préférence et tel que visible sur les figures en annexe, disposé sur tout le pourtour interne de ce dispositif 3.In fact, such a covering 25, 25 'is disposed on at least a portion of the inner periphery of said device 3 but is, preferably and as visible in the appended figures, disposed over the entire inner periphery of this device 3.
Cet habillage 25, 25' est implanté, de préférence, à proximité ou au niveau de l'extrémité 5 opposée à l'extrémité 6 orientée en direction de l'élément de séparation 1, plus particulièrement à proximité de l'ouverture 7 du dispositif 3. A ce propos, on observera que le matériau intumescent: est conçu apte à présenter une expansion pour une température correspondant à celle d'un incendie ce qui permet d'assurer une obturation de l'ouverture 7 du dispositif 3 (et, par conséquent, empêche toute circulation d'air au travers de ce dispositif 3) mais uniquement en cas d'incendie.This covering 25, 25 'is preferably located near or at the end opposite the end 6 facing towards the separating element 1, more particularly close to the opening 7 of the device. 3. In this respect, it will be observed that the intumescent material: is designed capable of exhibiting an expansion for a temperature corresponding to that of a fire, which makes it possible to seal the opening 7 of the device 3 (and, consequently, prevents any air circulation through this device 3) but only in case of fire.
Selon une autre caractéristique de l'invention, le dispositif 3 comporte, intérieurement, des moyens 26 conçus aptes à empêcher la traversée de ce dispositif 3 par des particules contenues dans un flux d'air, voire par un tel flux d'air. Ces moyens 26 sont conçus aptes à empêcher une telle traversée au moins pour une température inférieure à celle d'un incendie (à froid) , de préférence quelle que soit la température des locaux, notamment à température ambiante et plus particulièrement en l'absence d'incendie.According to another characteristic of the invention, the device 3 comprises, internally, means 26 designed capable of preventing the passage of this device 3 by particles contained in an air flow, or even by such a flow of air. These means 26 are designed to prevent such a crossing at least for a temperature lower than that of a fire (cold), preferably whatever the temperature of the premises, especially at room temperature and more particularly in the absence of 'fire.
A ce propos et selon un mode de réalisation préféré de l'invention, ces moyens 26 sont conçus en sorte d'empêcher le passage de particules présentant une taille supérieure à 1 micron, en particulier des particules de fumées et/ou de poussières, ceci plus particulièrement à froid, c'est-à-dire pour une température inférieure à celle d'un incendie, notamment à température ambiante.In this respect and according to a preferred embodiment of the invention, these means 26 are designed so as to prevent the passage of particles having a size greater than 1 micron, in particular particles of fumes and / or dust, this more particularly cold, that is to say for a temperature below that of a fire, especially at room temperature.
Un mode particulier de réalisation de ce mode de réalisation préféré consiste en ce que ces moyens 26 sont conçus en sorte d'empêcher le passage de tout flux d'air, ceci plus particulièrement à froid, de manière à garantir une étanchéité du dispositif 3.A particular embodiment of this preferred embodiment consists in that these means 26 are designed so as to prevent the passage of any flow of air, this more particularly cold, so as to ensure a seal of the device 3.
Une autre caractéristique de ces moyens 26 conçus aptes à empêcher la traversée de ce dispositif 3 par des particules ou par un flux d'air consiste en ce que ces moyens 26 sont conçus en un matériau apte, d'une part, à obturer intégralement le passage délimité par le corps tubulaire 4, intérieurement à ce dernier 4 et, d'autre part, à subir une déformation, de préférence réversible, afin d'épouser la forme des éléments traversants 2. Le fait: que ces moyens 26 soient: déformables et épousent la forme des éléments traversants 2 permet, avantageusement, à ces moyens 26 de s'adapter à toutes les formes, à toutes les sections ainsi qu'à un nombre variable d'éléments traversants 2 susceptibles d'être mis en place au travers du dispositif 3 coupe-feu selon l'invention et, ainsi, de garantir l'étanchéité de ce dispositif 3.Another characteristic of these means 26 designed to prevent the passage of this device 3 by particles or by an air flow is that these means 26 are designed of a material able, on the one hand, to completely seal the device. passage delimited by the tubular body 4, internally to the latter 4 and, secondly, to undergo a deformation, preferably reversible, in order to match the shape of the through elements 2. The fact that these means 26 are deformable and follow the shape of the through elements 2 advantageously allows these means 26 to adapt to all shapes, to all sections and to a variable number of through elements 2 can be put in place through the device 3 firestop according to the invention and, thus, to ensure the tightness of the device 3.
En particulier, ces moyens 26 autorisent, avantageusement, la mise en place de nouveaux éléments traversants 2 ou le retrait de certains de ces éléments traversants 2, notamment au niveau d'un dispositif 3 coupe-feu déjà implanté sur site, ceci tout en garantissant l'étanchéité de ce dispositif 3.In particular, these means 26 allow, advantageously, the introduction of new through elements 2 or the withdrawal of some of these through elements 2, particularly at a level 3 firebreak device already implanted on site, while ensuring the sealing of this device 3.
Ces moyens 26 sont implantés intérieurement audit tube 4 et, de préférence, à proximité ou au niveau de l'extrémité 6 orientée en direction de l'élément de séparation 1.These means 26 are implanted internally to said tube 4 and, preferably, near or at the level of the end 6 oriented in the direction of the separating element 1.
Ces moyens 26 sont rendus solidaires d'au moins une paroi interne d'au moins une portion 9 ; 10 de tube 4 et s'étendent, à partir de cette paroi, en direction d'une paroi interne de cette même portion 9 ; 10 de tube 4 ou de l'autre 10 ; 9 portion de tube 4.These means 26 are made integral with at least one inner wall of at least one portion 9; 10 of tube 4 and extend, from this wall, towards an inner wall of the same portion 9; 10 of tube 4 or the other 10; 9 portion of tube 4.
En fait, de tels moyens 26 peuvent être constitués par au moins une brosse ou par au moins un bloc de mousse 27, 27' (figures 1 à 3) , notamment une mousse de type viscoélastique, ou analogue. Un mode particulier de réalisation concerne des moyens 26 adoptant la forme d'une pluralité de blocs de mousse 27, 27' dont, d'une part, un bloc de mousse 27 implanté au niveau du support (plus particulièrement du profilé plan 15) que comporte une portion 9 de tube 4 et, d'autre part, au moins un bloc de mousse 27' (de préférence deux blocs disposés côte à côte comme visible figures 1 et 3) implanté au niveau de la partie intermédiaire 14 de l'autre portion 10 de tube 4 (profilé en « U » 11), ces blocs de mousse 27, 27' étant rendus solidaire du tube 4, notamment par collage. En fait, dans le passage, de tels moyens 26 s'étendent les uns 27 en direction des autres 27' et se rejoignent en sorte d'assurer l'obturation de ce passage.In fact, such means 26 may be constituted by at least one brush or at least one block of foam 27, 27 '(Figures 1 to 3), including a viscoelastic-type foam, or the like. A particular embodiment relates to means 26 adopting the shape of a plurality of foam blocks 27, 27 'of which, on the one hand, a block of foam 27 implanted at the level of the support (more particularly the plane profile 15) that comprises a portion 9 of tube 4 and, on the other hand, at least one foam block 27 '(preferably two blocks arranged side by side as shown in FIGS. 1 and 3) implanted at the intermediate portion 14 of the other portion 10 of tube 4 (section "U" 11), these foam blocks 27, 27 'being secured to the tube 4, in particular by gluing. In fact, in the passage, such means 26 extend towards each other 27 'and join so as to ensure the closure of this passage.
Un autre mode de réalisation consiste en ce que ces moyens 26 adoptent la forme d'une pluralité de brosses qui, à l'instar des blocs de mousse 27, 27' susmentionnés, peuvent être constitués par, d'une part, une brosse implantée au niveau du support que comporte une portion 10 de tube 4 et, d'autre part, au moins une brosse (de préférence deux brosses disposées côte à côte) implantée au niveau de la partie intermédiaire 14 de l'autre portion 9 de tube 4, ces brosses étant rendues solidaires du tube 4, notamment par collage.Another embodiment is that these means 26 take the form of a plurality of brushes which, like the aforementioned foam blocks 27, 27 ', can be constituted by, on the one hand, an implanted brush at the support that comprises a portion 10 of tube 4 and, secondly, at least one brush (preferably two brushes arranged side by side) implanted at the intermediate portion 14 of the other portion 9 of tube 4 these brushes being made integral with the tube 4, in particular by gluing.
Finalement et en ce qui concerne ces moyens 26, ceux-ci sont conçus pour empêcher la traversée du dispositif 3 coupe-feu au moins pour une température inférieure à celle d'un incendie de sorte que, pour une température correspondant à celle d'un incendie, l'étanchéité est garantie, soit par les moyens 24 susmentionnés qui prennent le relais des moyens 26, soit encore par l'ensemble de ces moyens 24 et 26. Selon une caractéristique additionnelle, le dispositif 3 comporte, encore, des moyens 28 conçus aptes à assurer une protection des moyens 26 pour empêcher la traversée de ce dispositif 3 par des particules contenues dans un flux d'air, voire par un tel flux d'air. De tels moyens de protection 28 sont conçus aptes à assurer une telle protection plus particulièrement en cas d'augmentation de la température, notamment en cas d'incendie.Finally and with respect to these means 26, these are designed to prevent the crossing of the device 3 firestop at least for a temperature below that of a fire so that for a temperature corresponding to that of a fire, sealing is guaranteed either by the aforementioned means 24 which take over the means 26, or by all of these means 24 and 26. According to an additional feature, the device 3 comprises, again, means 28. designed to provide protection means 26 to prevent the passage of the device 3 by particles contained in an air flow, or even by such an air flow. Such protection means 28 are designed to provide such protection more particularly in case of increase in temperature, especially in case of fire.
Plus précisément, ces moyens de protection 28 peuvent être conçus aptes à assurer une telle protection alors que les moyens 24 ne sont pas encore gonflés mais que les moyens 26 subissent déjà les contraintes d'une augmentation de la température.More specifically, these protection means 28 may be designed to provide such protection while the means 24 are not yet inflated but the means 26 are already under the constraints of an increase in temperature.
En fait, de tels moyens de protection 28 peuvent être réalisés en un matériau minéral, notamment de type intumescent. Cependant et selon un mode de réalisation préféré, de tels moyens de protection 28 sont réalisés en un matériau élastomère (plus particulièrement à base de PVC ou analogue) , notamment de type intumescent: (plus particulièrement: à base de graphite ou analogue) .In fact, such protection means 28 may be made of a mineral material, in particular of the intumescent type. However, and according to a preferred embodiment, such protection means 28 are made of an elastomeric material (more particularly based on PVC or the like), in particular intumescent type: (more particularly: based on graphite or the like).
De tels moyens de protection 28 adoptent, par exemple, la forme d'un cache, d'une nappe souple ou d'un rideau souple à lames juxtaposées, voire jointives (figure 1) , notamment en vue d'épouser la forme des éléments traversants 2.Such protection means 28 adopt, for example, the shape of a cover, a flexible sheet or a flexible curtain with juxtaposed or even contiguous blades (FIG. 1), especially in order to match the shape of the elements. through 2.
De tels moyens de protection 28 peuvent, par exemple, être implantés à proximité ou au niveau de l'extrémité 5, opposée à l'extrémité 6 orientée en direction de l'élément de séparation 1, plus particulièrement à proximité de l'ouverture 7 du dispositif 3 et à l'avant des moyens 24 pour empêcher une circulation d'air (figure 3) .Such protection means 28 may, for example, be located near or at the end 5, opposite the end 6 oriented towards the separating element 1, more particularly close to the opening 7 of the device 3 and in front of the means 24 to prevent air circulation (Figure 3).
Selon un autre mode de réalisation, de tels moyens de protection 28 peuvent être implantés entre les moyens 24 pour empêcher une circulation d'air et les moyens 26 pour empêcher la traversée du dispositif 3 par des particules ou par un flux d'air.According to another embodiment, such protection means 28 may be implanted between the means 24 to prevent air circulation and the means 26 to prevent the passage of the device 3 by particles or by a flow of air.
De tels moyens de protection 28 peuvent, encore, être implantés à l'avant et/ou à l'arrière des moyens 26 pour empêcher la traversée du dispositif 3 par des particules ou par un flux d'air, sachant qu'un mode préféré de réalisation (non représenté) consiste en ce que ces moyens de protection 28 sont implantés à l'avant et à l'arrière (c'est-à-dire de part et d'autre) de ces moyens 26. Ces moyens 24, 26, 28 sont, de préférence, implantés de manière juxtaposée tel que visible figure 3.Such protection means 28 may, again, be implanted at the front and / or rear of the means 26 to prevent the device 3 from passing through particles or by a stream of air, knowing that a preferred mode embodiment (not shown) is that these protection means 28 are located at the front and at the rear (that is to say on either side) of these means 26. These means 24, 26, 28 are preferably implanted juxtaposed as shown in FIG. 3.
Finalement et selon une caractéristique additionnelle de l'invention, le dispositif 3 coupe-feu peut, encore, comporter des moyens pour renforcer l'isolation thermique de ce dispositif 3. De tels moyens de renfort (non représentés) peuvent se présenter sous la forme d'une coque de protection disposée au moins en partie autour de ce dispositif 3, plus particulièrement par-dessus l'une au moins des deux portions 9, 10 du corps tubulaire 4. Un mode particulier de réalisation consiste en ce que ladite coque est constituée de deux parties dont l'une est conçue pour être disposée par-dessus la première portion 9 du corps tubulaire 4 tandis que l'autre partie est conçue pour être disposée par-dessus la seconde portion 10 de ce corps tubulaireFinally and according to an additional feature of the invention, the fire-resistant device 3 may, furthermore, comprise means for reinforcing the thermal insulation of this device 3. Such reinforcing means (not shown) may be in the form of a protective shell disposed at least partly around this device 3, more particularly over at least one of the two portions 9, 10 of the tubular body 4. A particular embodiment is that said shell is consisting of two parts, one of which is adapted to be disposed over the first portion 9 of the tubular body 4 while the other portion is adapted to be disposed over the second portion 10 of the tubular body
4. L'implantation de ces moyens de renfort se fait, de préférence, à une certaine distance du corps tubulaire 4 en sorte de ménager une lame d'air entre ce corps tubulaire 4 et ces moyens de renfort.4. The implantation of these reinforcing means is preferably at a distance from the tubular body 4 so as to provide an air gap between the tubular body 4 and these reinforcing means.
Ces moyens de renfort sont rendus solidaires du corps tubulaire 4 du dispositif 3 coupe-feu par le biais de moyens de solidarisation, de préférence constitués par des moyens de clipsage.These reinforcement means are made integral with the tubular body 4 of the firestop device 3 by means of securing means, preferably constituted by clipping means.
En fait de tels moyens de renfort peuvent être réalisés en un matériau métallique (plus particulièrement par découpage et pliage d'une plaque de tôle) , voire encore en un matériau synthétique, plus particulièrement par moulage. In fact such reinforcing means may be made of a metallic material (more particularly by cutting and folding a sheet metal plate), or even of a synthetic material, more particularly by molding.
