Description

Procédé de confinement et/ou d'isolation de zones polluées, en particulier par des poussières, et dispositif pour la mise en oeuvre de ce procédé Method for confining and / or isolating polluted areas, in particular by dust, and device for implementing this method
La présente invention concerne le domaine du confinement de zones polluées, en particulier par des poussières, notamment par des poussières nocives telles que les fibres d'amiante, et a pour objet un procédé de confinement et/ou d'isolation de zones polluées, en particulier par des poussières. L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé.The present invention relates to the field of confinement of polluted zones, in particular by dust, in particular by harmful dust such as asbestos fibers, and relates to a method of confinement and / or isolation of polluted zones, especially by dust. The invention also relates to a device for implementing this method.
Le risque de pollution de locaux par des poussières nocives dans tous les domaines liés à une présence humaine permanente ou non, ainsi que dans les domaines relatifs à l'alimentation, nécessite une surveillance permanente, afin, soit de vérifier l'absence d'une telle pollution, soit d'assurer le captage et le traitement de la pollution.The risk of pollution of premises with harmful dust in all areas related to a permanent human presence or not, as well as in areas relating to food, requires permanent monitoring, in order either to verify the absence of a such pollution, that is to ensure the capture and treatment of pollution.
Les locaux, dont certains équipements techniques, qui sont généralement accrochés sous le plafond, sont munis d'un revêtement isolant sous forme d'un flocage de fibres d'amiante ou d'autres fibres pouvant avoir des effets irritants ou toxiques, sont exposés, quelques années après la mise en oeuvre de tels flocages à un risque de délitement lent dudit flocage ayant pour effet un dégagement de fibres microscopiques sous forme de poussière. Ce dégagement s'effectue généralement dans le plénum délimité par un faux-plafond ne présentant aucune garanti d'étanchéité et ne permettant pas la rétention desdites poussières. Une telle poussière peut avoir des effets irritants ou toxiques pour les personnes évoluant dans les locaux, voire même, peuvent être à l'origine de pathologies graves. Ceci est particulièrement le cas des locaux pourvus d'une isolation à base d'amiante ou de bardages en amiante, ainsi que des locaux de stockage pourvus de toits en fibro-ciment à base d'amiante. De même, dans le cas de l'industrie agro-alimentaire, une pollution des produits entraîne un risque très important de transmission d'une pathologie par ingestion desdits produits. Ce risque peut également exister en ce qui concerne la transmission par les animaux, à savoir par consommation de lait ou d'abats.The premises, including certain technical equipment, which are generally hung under the ceiling, are provided with an insulating coating in the form of a flocking of asbestos fibers or other fibers which may have irritant or toxic effects, are exposed, a few years after the implementation of such flocking at a risk of slow disintegration of said flocking resulting in the release of microscopic fibers in the form of dust. This release is generally carried out in the plenum delimited by a false ceiling presenting no guarantee of tightness and not allowing the retention of said dust. Such dust can have irritating or toxic effects for people working in the premises, or even can be the cause of serious pathologies. This is particularly the case of premises provided with asbestos-based insulation or asbestos siding, as well as storage rooms provided with asbestos-based fiber cement roofs. Likewise, in the case of the food industry, product pollution involves a very significant risk of transmission of a pathology by ingestion of said products. This risk can also exist with regard to transmission by animals, namely by consumption of milk or offal.
Actuellement, cette pollution est combattue par suppression systématique des isolations existantes de ce type dans le cadre d'opérations dites de déflocage, au cours desquelles l'ensemble du produit formant les couches isolantes est décapé de ses supports et est récupéré par aspiration, puis est éliminé. Une telle opération de déflocage nécessite d'importantes mesures de confinement du site traité et doit être effectuée sous une pression négative par rapport au voisinage. Ceci entraîne la mise en oeuvre de moyens très coûteux. En outre, l'opération, qui est minutieuse, nécessite pour son accomplissement une durée de condamnation des locaux relativement longue, ce qui peut entraîner des effets économiques néfastes en termes de pertes d'exploitation.Currently, this pollution is combated by systematic removal of existing insulations of this type in the context of so-called deflocking operations, during which all of the product forming the insulating layers is stripped from its supports and is recovered by suction, then is eliminated. Such a deblocking operation requires significant containment measures of the treated site and must be carried out under negative pressure relative to the neighborhood. This leads to the implementation of very expensive means. In addition, the operation, which is meticulous, requires for its completion a relatively long period of condemnation of the premises, which can have negative economic effects in terms of operating losses.
La présente invention a pour but de pallier ces inconvénients en proposant un procédé de confinement et/ou d'isolation de zones polluées, en particulier par des poussières, ainsi qu'un dispositif pour la mise en oeuvre de ce procédé, permettant de confiner et/ou d'isoler rapidement une zone contaminée et/ou de surveiller la pollution dans un espace tampon, tout en maintenant les frais d'intervention et ceux liés à un éventuel arrêt de production dans des limites très faibles.The object of the present invention is to overcome these drawbacks by proposing a method for confining and / or isolating polluted zones, in particular by dust, as well as a device for implementing this method, making it possible to confine and / or quickly isolate a contaminated area and / or monitor pollution in a buffer space, while keeping intervention costs and those linked to a possible production shutdown within very low limits.
A cet effet, le procédé de confinement et/ou d'isolation de zones polluées, en particulier par des poussières, consiste essentiellement à délimiter un espace devant le support susceptible de former une pollution et à clore cet espace de manière étanche avec un dispositif de confinement.To this end, the method of confining and / or isolating polluted areas, in particular by dust, essentially consists in delimiting a space in front of the support capable of forming pollution and in closing this space in a sealed manner with a confinement.
L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, qui est essentiellement constitué par au moins un dispositif de confinement d'un espace étanche devant le support susceptible de former une pollution.The invention also relates to a device for implementing this method, which essentially consists of at least one device for confining a sealed space in front of the support capable of forming pollution.
L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels : la figure 1 est une vue partielle en élévation et en coupe d'un dispositif mettant en oeuvre le procédé conforme à l'invention ; la figure 2 est une vue partielle analogue à celle de la figure 1 représentant une variante de réalisation du procédé, et les figures 3 à 5 sont des vues partielles en coupe, analogues à celle de la figure 2, représentant d'autres variantes de réalisation de l'invention.The invention will be better understood from the following description, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which: FIG. 1 is a partial view in elevation and in section of a device implementing the method according to the invention; Figure 2 is a partial view similar to that of Figure 1 showing an alternative embodiment of the method, and Figures 3 to 5 are partial sectional views, similar to that of Figure 2, showing other alternative embodiments of the invention.
Conformément à l'invention, et comme le montrent, à titre d'exemples, les figures 1 à 5 des dessins annexés, le procédé de confinement et/ou d'isolation de zones polluées, en particulier par des poussières, consiste essentiellement à délimiter un espace 1 devant le support 2 susceptible de former une pollution et à clore cet espace 1 de manière étanche avec un dispositif de confinement. Un premier mode de réalisation du procédé, représenté à la figure 1 des dessins annexés, consiste à confiner provisoirement l'espace 1 et à collecter la pollution.In accordance with the invention, and as shown, by way of example, in FIGS. 1 to 5 of the appended drawings, the method of confining and / or isolating polluted areas, in particular by dust, essentially consists in delimiting a space 1 in front of the support 2 capable of forming pollution and of closing this space 1 in a sealed manner with a containment device. A first embodiment of the method, represented in FIG. 1 of the appended drawings, consists in temporarily confining the space 1 and in collecting the pollution.
Les figures 2 à 5 représentent un deuxième mode de réalisation du procédé, qui consiste à clore définitivement l'espace 1 et à fixer la pollution. Cette fixation de la pollution est obtenue par injection dans l'espace 1 d'un moyen fixateur isolant d'étanchement 3. Dans un tel cas, l'isolation et l'étanchéité du confinement sont garanties et vérifiées par création d'une lame d'air étanche 4.Figures 2 to 5 show a second embodiment of the method, which consists in permanently closing the space 1 and fixing the pollution. This fixation of the pollution is obtained by injection into space 1 of an insulating sealing sealing means 3. In such a case, the insulation and the tightness of the confinement are guaranteed and verified by creation of a blade d air tight 4.
Le dispositif de confinement pour la mise en oeuvre du procédé conforme à l'invention est essentiellement constitué par au moins un profilé 5 solidarisé avec le support 2 et/ou avec un ou plusieurs supports 1 1 convergeants avec le support 2, à distance de la partie polluée, et coopérant avec au moins un moyen 6 (figure 1) ou 7 (figures 2 à 5) de délimitation d'un espace étanche 1 devant ledit support 2. De préférence, le profilé 5 est appliqué contre le ou les supports 1 1 convergeant avec le support 2 avec interposition d'un joint d'étanchéité du type mastic-colle ou mastic de silicone. Ainsi, une étanchéité périphérique parfaite peut être assurée.The confinement device for implementing the method according to the invention essentially consists of at least one section 5 secured to the support 2 and / or with one or more supports 1 1 converging with the support 2, at a distance from the polluted part, and cooperating with at least one means 6 (Figure 1) or 7 (Figures 2 to 5) for delimiting a sealed space 1 in front of said support 2. Preferably, the profile 5 is applied against the support or supports 1 1 converging with the support 2 with the interposition of a sealant of the sealant or silicone sealant type. Thus, a perfect peripheral seal can be ensured.
Le profilé 5 constitutif du dispositif de confinement d'un espace étanche 1 est préférentiellement un profilé extrudé, s'étendant sur toute la périphérie de la surface à délimiter et comportant au moins une gorge 8 de fixation du bord du moyen 6 (figure 1) ou 7 (figures 2 à 5) de délimitation de l'espace 1. Ce profilé 5 est avantageusement muni d'un moyen 9 de suspension ou d'accrochage à distance à un support 2, ainsi que d'au moins un moyen 10 de solidarisation avec un support 1 1 convergeant avec le support 2. Selon le premier mode de réalisation de l'invention, représenté à la figure 1 des dessins annexés, le moyen 6 de délimitation de l'espace 1 est sous forme d'une poche, dont les bords sont insérés dans la gorge 8 de fixation ou d'accrochage du profilé 5 sur toute la périphérie de la surface à délimiter. Une telle poche 6 peut avantageusement s'étendre jusqu'au sol du local comportant le support 2 et être pourvue, en outre, d'un sas d'entrée et d'une conduite de raccordement à un dispositif de mise sous pression négative de types connus. Il en résulte la possibilité de créer un volume étanche de confinement permettant de réaliser des travaux de décontamination du support 2, tels que des travaux de déflocage. Les produits polluants dégagés lors de ces travaux peuvent être récupérés directement dans la poche 6, qui pourra être utilisée comme moyen de collecte de déchets ultimes. Ainsi, des travaux de dépollution pourront être effectués rapidement après la mise en place du profilé 5, puis l'accrochage de la poche 6 et le branchement des différents éléments annexes d'aspiration et de filtration. Les déchets produits restent dans la poche 6 qui, après décrochage du profilé périphérique 5, pourra alors être fermée de manière étanche en vue du transport vers le lieu de traitement final des déchets.The profile 5 constituting the confinement device of a sealed space 1 is preferably an extruded profile, extending over the entire periphery of the surface to be delimited and comprising at least one groove 8 for fixing the edge of the means 6 (FIG. 1) or 7 (FIGS. 2 to 5) for delimiting the space 1. This profile 5 is advantageously provided with a means 9 for remote suspension or attachment to a support 2, as well as at least one means 10 for fastening with a support 1 1 converging with the support 2. According to the first embodiment of the invention, shown in FIG. 1 of the accompanying drawings, the means 6 for delimiting the space 1 is in the form of a pocket, the edges of which are inserted into the groove 8 for fixing or hooking the profile 5 over the entire periphery of the surface to be delimited. Such a pocket 6 can advantageously extend to the floor of the room comprising the support 2 and be provided, in addition, with an entry airlock and with a connection pipe to a negative pressure device of the types known. This results in the possibility of creating a sealed containment volume making it possible to carry out decontamination works on the support 2, such as deflocking works. The pollutants released during these works can be recovered directly in pocket 6, which can be used as a means of collecting ultimate waste. So, depollution works could be carried out quickly after the installation of the section 5, then the attachment of the pocket 6 and the connection of the various additional suction and filtration elements. The waste produced remains in the pocket 6 which, after detaching the peripheral profile 5, can then be closed in a sealed manner for transport to the place of final treatment of the waste.
Ensuite, le profilé 5 pourra être utilisé, de manière connue, pour la fixation d'une toile tendue ou analogue.Then, the section 5 can be used, in known manner, for fixing a stretched fabric or the like.
Dans le cas de mise en oeuvre du deuxième mode de réalisation du procédé, le moyen 7 de délimitation d'un espace étanche 1 devant le support 2 susceptible de former une pollution est avantageusement constitué, comme le montrent les figures 2, 4 et 5 des dessins annexés, par une toile tendue dans un plan parallèle au support 2 ou à une surface projetée de ce dernier et sur une surface correspondant à celle dudit support 2 ou de sa surface projetée, la tension de ladite toile étant réalisée par accrochage sur le profilé périphérique 5. Le support 2 pouvant être, soit sous forme d'un élément de fermeture supérieure tel qu'un plafond ou un toit, soit sous forme d'une paroi verticale ou légèrement inclinée, la surface du moyen 7 pourra être égale à celle du support 2 ou inférieure à cette dernière, suivant que ledit moyen 7 s'étendra parallèlement au support 2 ou à une projection de ce dernier. Le moyen fixateur isolant d'étanchement 3, disposé entre le moyen 7 de délimitation de l'espace 1 et le support 2 susceptible de former une pollution, est, de préférence, constitué par une agglomération de billes de mousse expansée remplissant l'espace 1 et se liant entre-elles sous l'effet de la pression (figures 2 et 4). De telles billes peuvent être introduite dans l'espace I par l'intermédiaire d'un transporteur à air comprimé et à buse de projection. Ainsi, les billes constitutives du moyen fixateur 3 forment un bloc rigide isolant et empêchant toute propagation éventuelle de poussières se détachant du support 2. Ces billes sont avantageusement des billes de polystyrène expansé.In the case of implementing the second embodiment of the method, the means 7 for delimiting a sealed space 1 in front of the support 2 liable to form pollution is advantageously constituted, as shown in FIGS. 2, 4 and 5 of the attached drawings, by a canvas stretched in a plane parallel to the support 2 or to a projected surface of the latter and on a surface corresponding to that of said support 2 or of its projected surface, the tension of said canvas being produced by hanging on the profile peripheral 5. The support 2 can be either in the form of an upper closing element such as a ceiling or a roof, or in the form of a vertical or slightly inclined wall, the surface of the means 7 may be equal to that of support 2 or less than the latter, depending on whether said means 7 extend parallel to support 2 or a projection of the latter. The insulating sealing sealing means 3, disposed between the means 7 for delimiting the space 1 and the support 2 capable of forming pollution, is preferably constituted by an agglomeration of balls of expanded foam filling the space 1 and binding together under the effect of pressure (Figures 2 and 4). Such balls can be introduced into space I via a compressed air conveyor and a spray nozzle. Thus, the balls constituting the fixing means 3 form a rigid insulating block and preventing any possible propagation of dust detaching from the support 2. These balls are advantageously expanded polystyrene balls.
Selon une variante de réalisation de l'invention, le moyen fixateur isolant d'étanchement 3 peut également être constitué sous forme d'une mousse expansible projetée dans l'espace 1. Une telle mousse a le même effet que les billes agglomérées en permettant un remplissage total de l'espace 1 et en s'appliquant contre le support 2.According to an alternative embodiment of the invention, the sealing insulating fixing means 3 can also be formed in the form of an expandable foam sprayed into the space 1. Such a foam has the same effect as the agglomerated beads by allowing a total filling of space 1 and pressing against support 2.
Dans les modes de réalisation suivant les figures 2 à 5, dans lesquels l'espace 1 est clos définitivement et la pollution fixée, le dispositif de confinement est complété par un deuxième moyen 12 de délimitation de la lame d'air étanche 4 en avant de l'espace 1 comportant le moyen fixateur isolant d'étanchement 3 qui est avantageusement également constitué par une toile tendue dans un plan parallèle au moyen 7 de délimitation de l'espace 1 devant le support 2 et sur une surface correspondant également à celle dudit moyen 7 de délimitation, la tension de ladite toile étant réalisée par accrochage dans une gorge inférieure 13 du profilé 5.In the embodiments according to FIGS. 2 to 5, in which the space 1 is definitively closed and the pollution fixed, the confinement device is completed by a second means 12 for delimiting the airtight seal 4 in front of space 1 comprising the insulating sealing sealing means 3 which advantageously also consists of a fabric stretched in a plane parallel to the means 7 for delimiting the space 1 in front of the support 2 and on a surface also corresponding to that of said delimitation means 7, the tension of said fabric being produced by hanging in a lower groove 13 of the section 5.
Les toiles tendues formant les moyens 7 et 12 sont avantageusement du type de celles utilisées pour la réalisation de faux-plafonds tendus et comportent sur leur pourtour un crochet ou harpon destiné à coopérer avec une gorge d'accrochage correspondante 8 ou 13 du profilé 5. Le moyen 9 de suspension ou d'accrochage à distance à un support 2 est constitué sous forme d'un rail et coopère avec des suspentes ou écarteurs réglables 14 fixés au support 2. Il est ainsi possible de réaliser un réglage parfait de l'écartement entre le support 2 et le moyen 7 de délimitation, parallèlement ou suivant des plans différents, et d'agir, de ce fait sur le volume de l'espace 1 et donc du moyen fixateur isolant d'étanchement 3.The stretched fabrics forming the means 7 and 12 are advantageously of the type of those used for the production of stretched false ceilings and have on their periphery a hook or harpoon intended to cooperate with a corresponding hanging groove 8 or 13 of the profile 5. The means 9 for remote suspension or attachment to a support 2 is formed in the form of a rail and cooperates with adjustable lines or spacers 14 fixed to the support 2. It is thus possible to achieve perfect adjustment of the spacing between the support 2 and the means 7 for delimitation, in parallel or according to different planes, and therefore to act on the volume of the space 1 and therefore of the insulating sealing sealing means 3.
Les gorges de fixation 8 et inférieure 13 d'accrochage des bords des toiles tendues formant les moyens 7 et 12 se présentent sous forme de rails en U à ailes égales ou inégales, dont au moins une face interne d'une aile est pourvue d'une nervure 8' ou 13' destinée à coopérer avec le bord correspondant des toiles formant les moyens 7 et 12.The fixing grooves 8 and lower 13 for hooking the edges of the stretched fabrics forming the means 7 and 12 are in the form of U-shaped rails with equal or unequal wings, at least one internal face of a wing of which is provided with a rib 8 'or 13' intended to cooperate with the corresponding edge of the fabrics forming the means 7 and 12.
Selon une autre caractéristique de l'invention, le profilé extrudé 5 est pourvu à sa partie inférieure d'une deuxième gorge inférieure 13", dont l'ouverture s'étend perpendiculairement à la première gorge inférieure 13. Une telle gorge permet une fermeture simultanée d'un espace, pollué ou non, s'étendant dans une autre direction que celle du support 2 (figure 2) ou encore la mise en place du deuxième moyen de délimitation 12, sans apparition d'un joint latéral (figure 3).According to another characteristic of the invention, the extruded profile 5 is provided at its lower part with a second lower groove 13 ", the opening of which extends perpendicular to the first lower groove 13. Such a groove allows simultaneous closing of a space, polluted or not, extending in a direction other than that of the support 2 (Figure 2) or even the establishment of the second delimitation means 12, without the appearance of a lateral seal (Figure 3).
Le moyen 10 de solidarisation avec un support 1 1 convergeant avec le support 2 se présente sous forme d'un rail, dont le fond est muni d'une rainure de centrage de perçage et de vissage pour des vis de fixation 15, ce rail formant simultanément un guide de montage des extrémités du profilé sur des équerres d'assemblage.The means 10 for securing with a support 1 1 converging with the support 2 is in the form of a rail, the bottom of which is provided with a drilling and screw centering groove for fixing screws 15, this rail forming simultaneously a guide for mounting the ends of the profile on assembly brackets.
Selon une caractéristique de l'invention, pour éviter une déformation ttop importante du premier moyen de délimitation 7 sous la charge du moyen fixateur isolant d'étanchement 3, le dispositif est complété par des moyens 16 de rigidification et de support, sous forme de traverses ou de plaques, disposées à intervalles réguliers ou jointivement sur le moyen de solidarisation 10 du profilé 5 de fixation des moyens de délimitation 7 et 12 sur le support 2 susceptible de former une pollution et/ou sur un ou plusieurs supports 11 convergeant avec le support 2, ou guidés par leurs extrémités dans ledit moyen 10. Ainsi, une surcharge de la toile formant le moyen 7 pourra aisément être reprise par les moyens 16, sans effet néfaste sur le deuxième moyen 12 (figure 2). La figure 3 des dessins annexés représente une variante de réalisation de l'invention, dans laquelle un filet ou un treillis 17 est tendu sur le moyen de solidarisation 10 du profilé 5 par l'intermédiaire d'un bourrelet périphérique 17' coopérant avec les bords du rail formant ledit moyen de solidarisation 10. Un tel filet ou treillis permet également d'assurer une reprise de surcharge s'exerçant éventuellement sur le moyen 7.According to a characteristic of the invention, to avoid a significant ttop deformation of the first delimitation means 7 under the load of the insulating sealing sealing means 3, the device is completed by means 16 of stiffening and support, in the form of crosspieces or of plates, arranged at regular or joint intervals on the fastening means 10 of the profile 5 for fixing the delimiting means 7 and 12 on the support 2 capable of form pollution and / or on one or more supports 11 converging with the support 2, or guided by their ends in said means 10. Thus, an overload of the fabric forming the means 7 can easily be taken up by the means 16, without effect detrimental to the second plea 12 (Figure 2). Figure 3 of the accompanying drawings shows an alternative embodiment of the invention, in which a net or a trellis 17 is stretched over the securing means 10 of the profile 5 by means of a peripheral bead 17 'cooperating with the edges of the rail forming said securing means 10. Such a net or trellis also makes it possible to ensure a resumption of overload possibly exerted on the means 7.
Conformément à une autre caractéristique de l'invention, la lame d'air étanche 4 peut avantageusement être reliée à un dispositif d'analyse de la qualité de l'air, non représenté, à fonctionnement cyclique ou continu, par l'intermédiaire d'une prise d'air 18 débouchant dans ladite lame d'air 4 et reliée audit dispositif d'analyse. Ainsi, la qualité de l'air stagnant sous l'espace 1 isolé par le moyen 3 peut être contrôlé à tout moment et une fuite éventuelle de pollution peut également être détectée (figure 4).According to another characteristic of the invention, the sealed air space 4 can advantageously be connected to a device for analyzing the air quality, not shown, with cyclic or continuous operation, by means of an air intake 18 opening into said air gap 4 and connected to said analysis device. Thus, the quality of the air stagnating under the space 1 isolated by the means 3 can be checked at any time and a possible leak of pollution can also be detected (FIG. 4).
La figure 5 des dessins annexés représente une autre variante de réalisation de l'invention, dans laquelle le dispositif est combiné avec un élément intermédiaire 19 d'accrochage des moyens 7 et 12 de délimitation, cet élément intermédiaire 19 présentant des ailes symétriques longitudinales et étant pourvu sur chaque aile d'une gorge supérieure 20 et d'au moins une gorge inférieure 21 d'accrochage des bords respectifs des moyens 7 et 12 de délimitation. Ainsi, il est possible de réaliser une fermeture de surfaces de largeur supérieure à celle d'un lé de toile par liaison des bords avec l'élément 19. Un tel élément intermédiaire 19 peut être fixé à un support 2 au moyen de suspentes ou autres coopérant avec un rail 19' prévu à cet effet à sa partie supérieure.Figure 5 of the accompanying drawings shows another alternative embodiment of the invention, in which the device is combined with an intermediate element 19 for hooking means 7 and 12 for delimitation, this intermediate element 19 having longitudinal symmetrical wings and being provided on each wing with an upper groove 20 and at least one lower groove 21 for hooking the respective edges of the means 7 and 12 for delimitation. Thus, it is possible to make a closure of surfaces of width greater than that of a web of canvas by connecting the edges with the element 19. Such an intermediate element 19 can be fixed to a support 2 by means of lines or the like. cooperating with a rail 19 'provided for this purpose at its upper part.
Selon une autre caractéristique de l'invention, l'élément intermédiaire 19 d'accrochage des moyens 7 et 12 de délimitation peut avantageusement être pourvu, entre ses ailes symétriques longitudinales, d'une rampe d'éclairage 22 ou d'autres accessoires.According to another characteristic of the invention, the intermediate element 19 for hooking means 7 and 12 for delimitation can advantageously be provided, between its longitudinal symmetrical wings, with a light bar 22 or other accessories.
L'invention a été décrite en liaison avec des applications à la dépollution ou à la lutte contre la pollution par des poussières nocives. Cependant, l'invention est également applicable dans le domaine de la rénovation et de l'isolation, le moyen fixateur isolant d'étanchement 3 pouvant être utilisé comme une dalle ou un revêtement isolant. Grâce à l'invention, il est possible de réaliser un confinement et/ou une isolation de zones polluées, en particulier par des poussières, et ainsi de confiner et/ou d'isoler rapidement une zone contaminée et de la décontaminer ou de surveiller la pollution dans un espace tampon, tout en maintenant les frais d'intervention et ceux liés à un éventuel arrêt de production dans des limites très faibles.The invention has been described in connection with applications to depollution or to the fight against pollution by harmful dust. However, the invention is also applicable in the field of renovation and insulation, the insulating sealing sealing means 3 can be used as a slab or an insulating coating. Thanks to the invention, it is possible to achieve containment and / or isolation of polluted areas, in particular by dust, and thus to quickly contain and / or isolate a contaminated area and to decontaminate or monitor the pollution in a buffer space, while keeping intervention costs and those linked to a possible production shutdown within very low limits.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés 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 embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
