PROCEDE POUR LA REALISATION D’UNE STRUCTURE TENDUE D’ENTRETIEN AISE, FORMEE D’AU MOINS UN FILM DE POLYMERE THERMOPLASTIQUE, ET STRUCTURE TENDUE  METHOD FOR PRODUCING A TENSIBLE MAINTENANCE STRUCTURE, FORMED OF AT LEAST ONE THERMOPLASTIC POLYMER FILM, AND TENDENT STRUCTURE
REALISEE SELON UN TEL PROCEDE  IMPLEMENTED BY SUCH A METHOD
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
[001] L’invention concerne le domaine technique des structures tendues se présentant sous la forme de bandes, panneaux ou dalles. [001] The invention relates to the technical field of tensile structures in the form of strips, panels or slabs.
[002] L'invention concerne plus particulièrement un procédé pour la réalisation d’une structure tendue antistatique, fixée sur un support, et formée d’au moins un film de polymère thermoplastique, avantageusement en ETFE (éthylène tétrafluoroéthylène) ainsi qu’une structure tendue réalisée selon un tel procédé. The invention relates more particularly to a method for producing an antistatic tensile structure, fixed on a support, and formed of at least one thermoplastic polymer film, preferably ETFE (ethylene tetrafluoroethylene) and a structure tension carried out according to such a method.
[003] Le procédé est destiné notamment, mais non exclusivement, à la réalisation de structures tendues destinées à être fixées sur des supports transparents tels que des parois vitrées ou similaires, ou sur des supports dont il convient de conserver la visibilité comme par exemple des plafonds ou murs décorés. [003] The method is intended in particular, but not exclusively, for the production of tensile structures intended to be fixed on transparent supports such as glass walls or the like, or on supports whose visibility must be maintained, for example ceilings or decorated walls.
ETAT DE LA TECHNIQUE STATE OF THE ART
[004] L’utilisation de films de polymère thermoplastique pour la réalisation de structures tendues destinées à être installées devant des structures telles que des parois murales, des plafonds ou autres, est connue. [004] The use of thermoplastic polymer films for the production of tensile structures intended to be installed in front of structures such as walls, ceilings or the like, is known.
[005] Les films de polymère thermoplastique présentent l’inconvénient d’accumuler les charges d'électricité statique en surface. Les poussières ont donc tendance à venir s’y fixer et s’y accumuler par aimantation liée à la charge du support. [005] Thermoplastic polymer films have the disadvantage of accumulating the charges of static electricity on the surface. Dust tends to settle and accumulate by magnetization related to the load of the support.
[006] La présence de poussières est d’autant plus visible sur les films de polymère thermoplastique transparents destinés à être installés devant des parois vitrées ou devant des structures dont on souhaite conserver la visibilité. [006] The presence of dust is all the more visible on transparent thermoplastic polymer films intended to be installed in front of glazed walls or in front of structures whose visibility it is desired to maintain.
[007] Les structures tendues réalisées à partir de films de polymère thermoplastique requièrent donc une maintenance (nettoyage) coûteuse en terme de temps. En outre, le nettoyage de structures tendues restent peut aisé et comporte le risque, à chaque opération de nettoyage, d’abîmer la structure (impact sur la tension de la toile, détérioration du film lui-même, etc.). [008] L’invention vise à remédier à ces problèmes en proposant un procédé pour la réalisation d’une structure tendue d’entretien simple et rapide, avec une fréquence d’entretien fortement réduite au regard de celle requise par les structures tendues de l’art antérieur. [007] Tensile structures made from thermoplastic polymer films therefore require expensive maintenance (cleaning) in terms of time. In addition, the cleaning of tensioned structures can remain easy and carries the risk, at each cleaning operation, to damage the structure (impact on the tension of the fabric, deterioration of the film itself, etc.). [008] The invention aims to remedy these problems by proposing a method for producing a simple and fast maintenance tensile structure, with a maintenance frequency greatly reduced compared to that required by the tensile structures of the invention. prior art.
[009] OBJET DE L’INVENTION [009] OBJECT OF THE INVENTION
[0010] A cet effet, et selon un premier aspect, l’invention propose un procédé pour la réalisation d’une structure tendue antistatique fixée à un support et formée d’au moins un film de polymère thermoplastique comme par exemple un film en ETFE. Le procédé selon l’invention est remarquable en ce que, après installation de ladite structure au support, le film de polymère thermoplastique est traité par ionisation pour éliminer les charges électrostatiques présentes en surface dudit film. For this purpose, and according to a first aspect, the invention provides a method for producing an antistatic tensile structure attached to a support and formed of at least one thermoplastic polymer film, for example an ETFE film. . The method according to the invention is remarkable in that, after installation of said structure to the support, the thermoplastic polymer film is treated by ionization to eliminate the electrostatic charges present on the surface of said film.
[0011] Grâce au traitement par ionisation de la surface du film de polymère thermoplastique, les charges électrostatiques existantes sur le film sont éliminées, empêchant ainsi par la suite l’accumulation de poussières sur le film. Thanks to the ionization treatment of the surface of the thermoplastic polymer film, the electrostatic charges existing on the film are removed, thereby preventing the accumulation of dust on the film.
[0012] Le terme « film » désigne également dans la présente demande les termes de « toile » ou « nappe ». The term "film" also refers in this application to the terms "web" or "web".
[0013] Avantageusement, un soufflage d’air est appliqué en surface du film de polymère thermoplastique. Le soufflage d’air peut être réalisé concomitamment au traitement par ionisation du film ou à la suite du traitement par ionisation. Cela permet ainsi d’enlever les poussières présentes en surface du film. Advantageously, an air blast is applied to the surface of the thermoplastic polymer film. The air blowing can be performed concomitantly with the ionization treatment of the film or following the ionization treatment. This makes it possible to remove the dust present on the surface of the film.
[0014] Afin de maintenir le caractère antistatique de la structure tendue, il peut être prévu de réitérer sur le film de polymère thermoplastique le traitement par ionisation et le cas échéant de soufflage d’air. Ces opérations pourront être avantageusement précédées d’un nettoyage de la toile. Avantageusement, les opérations d’ionisation et de soufflage peuvent être renouvelées autant de fois que nécessaire. In order to maintain the antistatic nature of the tensile structure, it may be provided to repeat on the thermoplastic polymer film treatment by ionization and optionally air blowing. These operations can be advantageously preceded by a cleaning of the canvas. Advantageously, the ionization and blowing operations can be repeated as many times as necessary.
[0015] Avantageusement, le film de polymère thermoplastique comporte des micro perforations. [0015] Advantageously, the thermoplastic polymer film comprises micro perforations.
[0016] Avantageusement, le film de polymère thermoplastique est en tout ou partie transparent ou translucide. [0016] Advantageously, the thermoplastic polymer film is wholly or partially transparent or translucent.
[0017] L’invention concerne également une structure tendue obtenue suivant le procédé précédemment décrit. [0018] Avantageusement, la structure tendue comporte au moins deux films de polymère thermoplastique superposés. The invention also relates to a tensile structure obtained according to the previously described method. Advantageously, the tensile structure comprises at least two superposed thermoplastic polymer films.
[0019] Avantageusement, la structure tendue se présente sous la forme d’une bande ou panneau d’au moins un film de polymère thermoplastique, ou d’une dalle constituée d’un cadre sur lequel le film de polymère thermoplastique est tendu. Advantageously, the tensile structure is in the form of a strip or panel of at least one thermoplastic polymer film, or a slab consisting of a frame on which the thermoplastic polymer film is stretched.
[0020] Avantageusement, le(s) film(s) de polymère thermoplastique est (sont) en ETFE. [0020] Advantageously, the thermoplastic polymer film (s) is (are) made of ETFE.

DESCRIPTION DETAILLEE DES FIGURES DETAILED DESCRIPTION OF THE FIGURES
[0023] La figure 1 illustre une structure tendue 1 fixée sur le plafond 2 d’un local 3. Dans l’exemple illustré, la structure tendue 1 est formée de panneaux 10. Sur la figure 1, seuls trois panneaux 10 sont représentés. Figure 1 illustrates a tensile structure 1 fixed to the ceiling 2 of a room 3. In the example shown, the tensile structure 1 is formed of panels 10. In Figure 1, only three panels 10 are shown.
[0024] Dans l’exemple décrit, chaque panneau 10 est formé d’un unique film 4 de polymère thermoplastique, avantageusement en ETFE (éthylène tétrafluoroéthylène) (figure 2). Le film 4 de polymère thermoplastique est micro-perforé afin d’améliorer les propriétés acoustiques du local dans lequel il est installé, la présence de micro-perforations permettant l’absorption des ondes acoustiques et ainsi la réduction du niveau sonore du local 3. [0025] Par ailleurs, destiné principalement à être disposé devant des parois vitrées ou devant des structures dont la visibilité doit être conservée, le film 4 de polymère thermoplastique est avantageusement transparent ou translucide. In the example described, each panel 10 is formed of a single film 4 of thermoplastic polymer, preferably ETFE (ethylene tetrafluoroethylene) (Figure 2). The film 4 of thermoplastic polymer is micro-perforated to improve the acoustic properties of the room in which it is installed, the presence of micro-perforations for the absorption of acoustic waves and thus the reduction of the sound level of the room 3. Furthermore, intended primarily to be arranged in front of glass walls or structures whose visibility must be preserved, the film 4 of thermoplastic polymer is preferably transparent or translucent.
[0026] Afin d’éliminer les charges électrostatiques et donc l’accumulation des poussières au cours du temps sur sa surface, le film 4 de polymère thermoplastique de chaque panneau 10 est soumis à un traitement par ionisation. Ce traitement est réalisé une fois le film 4 tendu et fixé sur le plafond 2. L’action d’ioniser est indiquée sur la figure 1 par la référence 10. In order to eliminate the electrostatic charges and therefore the accumulation of dust over time on its surface, the film 4 of thermoplastic polymer of each panel 10 is subjected to ionization treatment. This treatment is carried out once the film 4 is stretched and fixed on the ceiling 2. The ionizing action is indicated in FIG. 1 by reference numeral 10.
[0027] Selon un mode de réalisation préféré, le traitement par ionisation 20 est réalisé concomitamment avec un soufflage d’air 30 sur le film 4 de polymère thermoplastique. Cela permet de dépoussiérer le film 4 et d’enlever les charges électrostatiques présentes à sa surface. Ces opérations sont réalisées avantageusement à l’aide par exemple d’un pistolet soufflant ionisant 5 ou d’une soufflette ionisante représenté sur la figure 1. According to a preferred embodiment, the ionization treatment 20 is carried out concomitantly with an air blowing 30 on the film 4 of thermoplastic polymer. This makes it possible to dust the film 4 and to remove the electrostatic charges present on its surface. These operations are advantageously carried out using, for example, an ionizing blower gun 5 or an ionizing blower shown in FIG.
[0028] Ces opérations de dépoussiérage et d’ionisation 10 sont réitérées de préférence dès lors toute manipulation du film 4, et ce afin d’éliminer les éventuelles poussières déposées sur le film 4 lors de sa manipulation et de supprimer toute charge électrostatique générée à cette occasion. These dust removal and ionization operations 10 are preferably reiterated from any handling of the film 4, and this in order to eliminate any dust deposited on the film 4 during handling and remove any electrostatic charge generated at this occasion.
[0029] Dans l’exemple illustré sur la figure 2, la structure tendue 1 est formée d’une seule couche de film 4 de polymère thermoplastique. Il peut bien entendu être prévu une structure tendue 1 formée d’une superposition de couches de films. La figure 3 montre un exemple de structure tendue 1 formée de deux couches de films 4A, 4B superposées et disposées à distance l’une de l’autre. L’avantage de prévoir un arrangement en double couche est l’optimisation acoustique du local et en particulier l’amélioration de l’isolation acoustique. Il peut bien entendu être prévu également une structure tendue 1 formée de couches superposées en contact directement les unes avec les autres sans sortir du cadre de l’invention In the example illustrated in Figure 2, the tensile structure 1 is formed of a single layer of film 4 of thermoplastic polymer. It can of course be provided a tensile structure 1 formed of a superposition of film layers. FIG. 3 shows an example of a stretched structure 1 formed of two layers of films 4A, 4B superimposed and arranged at a distance from one another. The advantage of providing a double layer arrangement is the acoustic optimization of the room and in particular the improvement of the acoustic insulation. It can of course also be provided a tensile structure 1 formed of superposed layers in direct contact with each other without departing from the scope of the invention
[0030] Dans les exemples illustrés, la structure tendue 1 se présente sous la forme de panneaux 10 de forme rectangulaire. La structure tendue 1 peut bien entendu présenter toute formes diverses sans sortir du cadre de l’invention. De même, elle peut se présenter sous forme autre que celle de panneau. En particulier, elle peut se présenter sous la forme de bandes de film 4. In the illustrated examples, the tensile structure 1 is in the form of panels 10 of rectangular shape. The tensile structure 1 can of course have any shape without departing from the scope of the invention. Likewise, it may be in a form other than that of a panel. In particular, it can be in the form of film strips 4.
[0031] De même, dans les exemples illustrés, les panneaux 10 sont fixés directement au plafond au moyen de systèmes de fixation tels que des équilibreurs 5. Il peut être prévu également que le film ou les films soi(en)t fixé(s) tendu(s) sur un cadre qui sera alors raccordé au support concerné sans sortir du cadre de l’invention. Similarly, in the illustrated examples, the panels 10 are fixed directly to the ceiling by means of fastening systems such as balancers 5. It can be provided also that the film or films are fixed (s) taut (s) on a frame which will then be connected to the support concerned without departing from the scope of the invention.
[0032] L’invention est décrite dans ce qui précède à titre d’exemple. Il est entendu que l’homme du métier est à même de réaliser différentes variantes de réalisation de l’invention sans pour autant sortir du cadre de l’invention. The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
