Description

La présente invention concerne une paroi d'isolation acoustique utilisable notamment, mais non exclusivement, à la réalisation de cabines telles que, par exemple, des cabines musicales, des cabines d'interprétation simultanée transportables, où même des cabines servant de postes de commande ou de surveillance situées dans un environnement bruyant.The present invention relates to an acoustic insulation wall that can be used, in particular, but not exclusively, to the production of cabins such as, for example, musical cabins, transportable simultaneous interpreting booths, where even cabins serving as control stations or in a noisy environment.

Elle a plus particulièrement pour but une paroi qui conjugue les propriétés suivantes :

  • une rigidité suffisante pour permettre son utilisation en tant que cloison ou de parois autoportantes, notamment les parois d'une cabine,
  • une légèreté pour faciliter le montage, le démontage et le transport,
  • une bonne aptitude à l'usinage, notamment pour la réalisation de baies ou même l'incorporation d'éléments de fixation ou même d'accessoires tels que des charnières, des éléments de fermeture (serrures, grille de ventilation, circuits électriques, informatiques, etc...),
  • d'excellentes propriétés d'isolation phonique et thermique,
  • une bonne tenue au choc.
More particularly, it aims at a wall that combines the following properties:
  • a sufficient rigidity to allow its use as a partition or freestanding walls, including the walls of a cabin,
  • a lightness to facilitate assembly, disassembly and transportation,
  • a good machinability, especially for the production of racks or even the incorporation of fasteners or even accessories such as hinges, closing elements (locks, ventilation grille, electrical circuits, computer, etc ...)
  • excellent sound and heat insulation properties,
  • good resistance to shock.

D'une manière générale, on sait qu'il existe déjà des cabines démontables et transportables spécialement conçues pour assurer une isolation phonique. Ces cabines sont réalisées par assemblage de parois habituellement réalisées en matériau traditionnel comportant des plaques rigides habituellement en contreplaqué ou aggloméré de bois, revêtu d'une ou plusieurs couches de matière isolante sur le plan acoustique. En fait, dans ces parois, la résolution des problèmes mécaniques et ceux relatifs à l'isolation acoustique, sont dissociés, les plaques de contreplaqué répondant aux problèmes de structure et la couche d'isolation phonique étant destinée à assurer, à elle seule, la fonction d'isolation phonique, étant entendu que le contreplaqué ou l'aggloméré de bois ne présente pas en général de bonnes propriétés d'isolation acoustique.In general, it is known that there are already removable and transportable cabins specially designed to provide sound insulation. These cabins are made by assembling walls usually made of traditional material having rigid plates usually plywood or chipboard, coated with one or more layers of acoustically insulating material. In fact, in these walls, the resolution of the mechanical problems and those relating to the acoustic insulation, are dissociated, the plywood plates answering the structural problems and the sound insulation layer being intended to ensure, on its own, the soundproofing function, it being understood that the plywood or the wood chip does not generally have good acoustic insulation properties.

En conséquence, ces parois sont relativement lourdes et épaisses et, en raison de leur poids élevé, entraînent une pénibilité importante pour les personnels de manutention, lors des montages et démontages fréquents.Consequently, these walls are relatively heavy and thick and, because of their high weight, cause significant difficulty for handling personnel, during assembly and frequent dismantling.

L'invention a donc plus particulièrement pour but de supprimer ces inconvénients.The object of the invention is therefore more particularly to eliminate these disadvantages.

Elle se base sur la constatation que l'atténuation que subit une onde se propageant dans un milieu est d'autant plus importante que ce milieu est hétérogène et qu'elle doit traverser un nombre élevé d'interfaces entre des matières différentes présentant des propriétés acoustiques différentes. Elle entend exploiter cette particularité en utilisant des matériaux présentant de faibles masses volumiques y compris de l'air.It is based on the observation that the attenuation experienced by a wave propagating in a medium is all the more important that this medium is heterogeneous and that it must pass through a large number of interfaces between different materials with acoustic properties. different. It intends to exploit this feature by using materials with low densities including air.

A cet effet, elle propose une paroi d'isolation thermique comportant une plaque autoportante réalisée en résine synthétique présentant une structure alvéolaire multicouche de faible densité, possédant une bonne résistance aux chocs, cette plaque autoportante étant revêtue d'un côté, par un matelas de matière isolante et une garniture de finition et de protection recouvrant le matelas de matière isolante.For this purpose, it proposes a thermal insulation wall comprising a self-supporting plate made of synthetic resin having a multilayer cellular structure of low density, having good impact resistance, this self-supporting plate being coated on one side by a mattress of insulating material and a finishing and protective lining covering the mattress of insulating material.

Avantageusement, la plaque autoportante pourra consister en une plaque en polycarbonate comportant deux parois extérieures parallèles ainsi qu'au moins une paroi intérieure qui s'étend parallèlement aux parois extérieures, les parois intérieures étant reliées entre elles et avec les parois extérieures par une multiplicité de cloisons transversales qui délimitent entre elles et avec les parois adjacentes des vides d'air constitués par une pluralité de canaux parallèles.Advantageously, the self-supporting plate may consist of a polycarbonate plate comprising two parallel outer walls and at least one inner wall which extends parallel to the outer walls, the inner walls being connected to each other and to the outer walls by a multiplicity of transverse partitions which delimit between them and with the adjacent walls air voids constituted by a plurality of parallel channels.

De préférence, les cloisons transversales s'étendant à partir de l'une des faces de l'une des parois intérieures sont perpendiculaires par rapport aux cloisons transversales qui s'étendent depuis l'autre face de cette paroi intérieure, de manière à ce que l'onde sonore qui se propage dans le polycarbonate traverse une succession de couches de matériaux de consistance différente.Preferably, the transverse partitions extending from one of the faces of one of the inner walls are perpendicular to the transverse partitions which extend from the other side of this inner wall, so that the sound wave that propagates in the polycarbonate passes through a succession of layers of materials of different consistency.

Un mode d'exécution de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :

  • La figure 1 est une vue en coupe schématique d'une paroi d'isolation acoustique selon l'invention ;
  • Les figures 2 et 3 sont des vues en perspective selon deux angles différents d'une cabine transportable d'interprétation simultanée utilisant des parois d'isolation présentant une structure analogue à celle de la figure 1.
One embodiment of the invention will be described below, by way of non-limiting example, with reference to the accompanying drawings in which:
  • The figure 1 is a schematic sectional view of an acoustic insulation wall according to the invention;
  • The Figures 2 and 3 are perspective views from two different angles of a transportable simultaneous interpretation booth using insulation walls having a structure similar to that of the figure 1 .

Dans l'exemple illustré sur ces dessins, le panneau d'isolation acoustique 1 est réalisé par la superposition de trois éléments successifs, à savoir : un premier élément consistant en une plaque de polycarbonate alvéolaire 2, un second élément consistant en un matelas 3 de mousse de matière composite présentant des propriétés d'isolation acoustique et un troisième élément consistant en une garniture 4 de finition et de protection du matelas 3.In the example illustrated in these drawings, the acoustic insulation panel 1 is formed by the superposition of three successive elements, namely: a first element consisting of a cellular polycarbonate plate 2, a second element consisting of a mattress 3 of composite material foam having acoustic insulation properties and a third element consisting of a trim and mattress protection pad 4.

La plaque de polycarbonate alvéolaire 2 comprend plusieurs feuilles de polycarbonate parallèles 5 à 8, reliées les unes aux autres par des cloisons transversales 9 qui délimitent, avec les feuilles qui leurs sont adjacentes, trois séries d'évidement, en forme de canaux longitudinaux 10.The cellular polycarbonate sheet 2 comprises a plurality of parallel polycarbonate sheets 5 to 8, connected to each other by transverse partitions 9 which delimit, with the sheets which are adjacent to them, three series of recesses, in the form of longitudinal channels 10.

Dans l'exemple représenté sur la figure 1, on a représenté une plaque 2 comportant quatre feuilles de polycarbonate 5 à 8, étant entendu que ce nombre n'est pas limitatif. En effet, la plaque 2 pourrait, par exemple, comprendre trois ou cinq feuilles.In the example shown on the figure 1 , there is shown a plate 2 comprising four sheets of polycarbonate 5 to 8, it being understood that this number is not limiting. Indeed, the plate 2 could, for example, comprise three or five sheets.

Grâce à sa structure alvéolaire, cette plaque 2 présente une bonne résistance mécanique (rigidité, résistance aux chocs) et ce, en dépit de sa légèreté. Ainsi, lors d'un choc léger, l'énergie exercée sur la paroi est absorbée par la déformation élastique, dans une zone localisée, des feuilles 5 à 8 et des cloisons 9. A la fin de l'impact, les feuilles 5 à 8 et les cloisons 9 reprennent leur forme initiale sans qu'il se soit produit de détérioration notable rémanente de la plaque. Lors d'un choc lourd, la paroi extérieure de la plaque de polycarbonate pourra subir une déformation permanente, sans pour autant entraîner des problèmes de structure ou une altération de ses qualités acoustiques.Thanks to its honeycomb structure, this plate 2 has good mechanical strength (rigidity, impact resistance) and this, despite its lightness. Thus, during a light impact, the energy exerted on the wall is absorbed by the elastic deformation, in a localized area, of the sheets 5 to 8 and the partitions 9. At the end of the impact, the sheets 5 to 8 and the partitions 9 resume their original shape without there having occurred significant residual deterioration of the plate. During a heavy impact, the outer wall of the polycarbonate plate may undergo permanent deformation, without causing structural problems or an alteration of its acoustic properties.

La plaque 2 peut être réalisée par extrusion et produite industriellement à des cadences élevées et à bas prix de revient.The plate 2 can be made by extrusion and produced industrially at high rates and low cost.

Sur le plan acoustique, il s'avère que cette plaque présente des propriétés d'isolation particulièrement intéressantes. En effet, lors de sa propagation à travers la plaque 2, une onde acoustique sera amenée à traverser un milieu hétérogène comportant une multiplicité d'interfaces polycarbonate/air et subira ainsi une pluralité d'atténuations successives. En outre, les ondes se propageant par les cloisons transversales 9 dans une structure cellulaire à résonances multiples seront donc également le siège de déperditions énergétiques importantes.Acoustically, it turns out that this plate has particularly interesting insulation properties. Indeed, during its propagation through the plate 2, an acoustic wave will be passed through a heterogeneous medium comprising a plurality of polycarbonate / air interfaces and will thus undergo a plurality of successive attenuations. In addition, the waves propagating through the transverse partitions 9 in a cellular structure to multiple resonances will therefore also be the seat of significant energy losses.

En conséquence, l'onde ressortant du panneau à l'opposé de l'onde incidente sera considérablement atténuée sur une très large plage de fréquence.As a result, the wave emerging from the panel opposite the incident wave will be considerably attenuated over a very wide frequency range.

A titre d'exemple, l'épaisseur de la plaque 2 pourra être d'environ 10 mm.For example, the thickness of the plate 2 may be about 10 mm.

Eventuellement, la plaque 2 pourra être revêtue d'un film de finition en chlorure de polyvinyle, par exemple de couleur grise, présentant une bonne tenue au feu (par exemple classe M1).Optionally, the plate 2 may be coated with a polyvinyl chloride finishing film, for example of gray color, having a good fire resistance (for example class M1).

Le matelas 3 de mousse de matière composite pourra présenter une épaisseur plus importante, par exemple de 20 mm. Sa densité pourra être choisie en fonction de la nature des ondes sonores à atténuer, étant entendu qu'il sera toujours nécessaire de faire un bon compromis poids/isolation acoustique. La mousse pourra être de type mousse acoustique classique.The mattress 3 of composite material foam may have a greater thickness, for example 20 mm. Its density may be chosen according to the nature of the sound waves to be attenuated, it being understood that it will always be necessary to make a good weight / sound insulation compromise. The foam may be of the conventional acoustic foam type.

La fixation du matelas 3 de mousse de matière composite sur la plaque de polycarbonate alvéolée pourra s'effectuer par l'intermédiaire de cordons de colle de type mastic 11 destinés à ménager entre la plaque et le matelas des vides d'air 12. Ces vides d'air 12 constituent des ruptures dans la transmission des ondes acoustiques qui se propagent de la plaque de polycarbonate vers le matelas de mousse et inversement.The attachment of the composite material foam mattress 3 to the cellular polycarbonate plate may be effected by means of mastic-type adhesive cords 11 intended to provide air gaps between the plate and the mattress 12. These voids air 12 constitute breaks in the transmission of acoustic waves that propagate from the polycarbonate plate to the foam mattress and vice versa.

La garniture de finition 4 pourra consister en une feuille de matière plastique de type simili cuir (par exemple blanc ou anthracite) présentant une multiplicité de perforations.The finishing lining 4 may consist of a plastic sheet of imitation leather type (for example white or anthracite) having a multiplicity of perforations.

La fixation de cette garniture 4 sur le matelas 3 en mousse est réalisée par collage.Fixing this liner 4 on the foam mattress 3 is made by gluing.

Les panneaux 1 présentant la structure précédemment décrite peuvent présenter des formes quelconques, notamment des formes polygonales.The panels 1 having the structure described above may have any shape, including polygonal shapes.

Dans le cas de la réalisation d'une cabine d'interprétation telle que celle qui est représentée sur les figures 2 et 3, ils pourront présenter la forme d'un quadrilatère, notamment d'un carré ou d'un rectangle.In the case of the realization of an interpretation booth such as the one shown on the Figures 2 and 3 they may have the shape of a quadrilateral, in particular a square or a rectangle.

Dans cette application, les côtés du quadrilatère sont renforcés par des éléments profilés 12, de section en forme de U, dans lesquels s'engagent et sont collés les bords des panneaux 1.In this application, the sides of the quadrilateral are reinforced by profiled elements 12, of U-shaped section, in which the edges of the panels 1 engage and are glued.

Ces profilés en U 12 constituent donc les montants et les traverses d'encadrements qui accroissent la rigidité des panneaux 1 assurant une protection périphérique notamment pour le matelas 3 en mousse de matière composite qui est relativement fragile, et facilitent leur assemblage. Compte tenu des caractéristiques mécaniques des plaques 2 en polycarbonate alvéolaire, ces montants et ces traverses peuvent être réalisés en un profilé d'aluminium relativement léger.These U-shaped profiles 12 thus constitute the uprights and crossmembers of frames that increase the rigidity of the panels 1 providing peripheral protection, particularly for the mattress 3 of composite material foam which is relatively fragile, and facilitate their assembly. Given the mechanical characteristics of the sheets 2 of cellular polycarbonate, these uprights and crosspieces can be made of a relatively light aluminum profile.

Un avantage de cette solution consiste en ce qu'elle permet d'éviter l'usage de poteaux d'angles jusqu'ici indispensables pour le montage.An advantage of this solution is that it avoids the use of corner posts hitherto indispensable for mounting.

L'assemblage des panneaux entre eux fait intervenir un joint de caoutchouc tunnel collé sur l'un des montants verticaux de chaque panneau et des moyens de fixation facilement déconnectables.The assembly of the panels between them involves a tunnel rubber seal glued to one of the vertical uprights of each panel and easily disconnectable fastening means.

Dans l'exemple illustré sur les figures 2 et 3, la cabine présente une forme parallélépipédique rectangle et fait intervenir dix panneaux, à savoir :

  • trois panneaux latéraux pleins 16, 17, 18,
  • quatre panneaux latéraux vitrés 19, 20, 21, 22,
  • un panneau constituant une porte 23,
  • deux panneaux de toiture 24, 25.
In the example shown on the Figures 2 and 3 , the cabin has a rectangular parallelepiped shape and involves ten panels, namely:
  • three solid side panels 16, 17, 18,
  • four glazed side panels 19, 20, 21, 22,
  • a panel constituting a door 23,
  • two roof panels 24, 25.

Les huit panneaux latéraux 16 à 23 présentent des dimensions identiques de sorte qu'ils autorisent une multiplicité de configuration de la cabine. En particulier, ils permettent de positionner la porte à l'emplacement le plus approprié compte tenu des infrastructures.The eight side panels 16 to 23 have identical dimensions so that they allow a multiplicity of configuration of the cabin. In particular, they allow to position the door at the most appropriate location given the infrastructure.

Le panneau de porte 23 comprend un cadre comportant deux montants 26, 27 et une traverse supérieure 28 réalisés en carré d'aluminium par exemple de 35 x 35 mm, et une traverse inférieure 29 consistant en un seuil de porte en acier par exemple de 35 x 5 mm revêtu d'une résine époxy, collé riveté. La faible épaisseur de ce seuil permet notamment le passage de fauteuils pour handicapés.The door panel 23 comprises a frame comprising two uprights 26, 27 and an upper cross member 28 made of aluminum square, for example 35 x 35 mm, and a lower cross member 29 consisting of a steel door sill, for example 35 x 5 mm epoxy coated, glued riveted. The small thickness of this threshold allows the passage of wheelchairs for the disabled.

Le panneau de porte 30 en lui-même est réalisé suivant le même modèle que les panneaux standards. Sa largeur est prévue de manière à permettre le passage d'un fauteuil pour handicapés. Une grille de ventilation 31 est fixée par collage au bas de porte.The door panel 30 itself is made in the same pattern as the standard panels. Its width is designed to allow the passage of a chair for the disabled. A ventilation grid 31 is fixed by gluing to the door bottom.

Les panneaux vitrés 19 à 22 comprennent une partie haute 32 et une partie basse 33 réalisées comme les panneaux standards et une partie centrale 34 consistant en une plaque de polycarbonate plein (par exemple d'épaisseur de 6 mm) traités anti-rayure. Cette plaque est tenue par des parcloses en aluminium vissées sur les montants et les traverses du panneau vitré avec interposition de joints phoniques collés.The glazed panels 19 to 22 comprise an upper part 32 and a lower part 33 made like the standard panels and a central part 34 consisting of a solid polycarbonate plate (for example 6 mm thick) treated anti-scratch. This plate is held by aluminum glazing beads screwed onto the uprights and the cross members of the glazed panel with the interposition of glued sound seals.

Les panneaux de toiture 24, 25 sont réalisés selon un même principe que les panneaux latéraux pleins. Ils peuvent être équipés d'un ventilateur destiné à assurer une circulation d'air à l'intérieur de la cabine.The roof panels 24, 25 are made according to the same principle as the solid side panels. They can be equipped with a fan to ensure air circulation inside the cabin.

Grâce à la légèreté des panneaux 16 à 25 et l'emploi de moyens de fixation facilement connectables et déconnectables entre les panneaux, le montage et le démontage de la cabine s'effectue très rapidement par une seule personne. En outre, une fois démontés, les panneaux peuvent être rangés dans une caisse munie de roulettes qui peut être facilement déplacée et transportée.Thanks to the lightness of the panels 16 to 25 and the use of easily connectable and disconnectable fastening means between the panels, the assembly and disassembly of the cabin is carried out very quickly by one person. In addition, once dismantled, the panels can be stored in a box with wheels that can be easily moved and transported.
