Description

L'invention concerne une structure acoustique de bâtiment destinée à être fixée sur l'ossature du bâtiment et comprenant au moins un ensemble acoustique qui comporte un panneau de laine minérale et un élément porteur dudit panneau de laine minérale.The invention relates to an acoustic building structure intended to be fixed on the building frame and comprising at least one acoustic assembly which comprises a mineral wool panel and a carrier element of said panel of mineral wool.

L'isolation acoustique d'un bâtiment est couramment obtenue à partir de structures du type masse-ressort-masse dont un exemple est donné dans le document EP 0921242. Une telle structure se compose de deux masses qui sont constituées chacune d'un élément rigide et qui sont séparées par un panneau de laine minérale, telle que de la laine de verre, associé à une lame d'air pour constituer le ressort. Les deux éléments rigides sont disposés de part et d'autre de l'ossature du bâtiment et fixés mécaniquement à cette même ossature ou à des lisses métalliques ajoutées à l'ossature. Ces éléments consistent en des plateaux en tôle de section en forme de U qui sont garnis à l'intérieur du U d'un panneau de laine minérale, telle que de la laine de roche, pour augmenter l'effet de masse.The acoustic insulation of a building is commonly obtained from mass-spring-mass structures, an example of which is given in the EP 0921242. Such a structure consists of two masses which are each consisting of a rigid element and which are separated by a panel of mineral wool, such as glass wool, combined with an air knife for constitute the spring. The two rigid elements are arranged on both sides of framework of the building and mechanically attached to the same framework or to metal rails added to the framework. These elements consist of trays in U-shaped section sheet which are lined inside the U of a panel of mineral wool, such as rock wool, to increase the mass effect.

La structure décrite dans ce document permet avantageusement de fixer directement les éléments rigides sur l'ossature du bâtiment ou à des lisses métalliques associées à l'ossature sans nécessiter de moyens de fixation intermédiaires. Cependant, la structure, par la nature en tôle et la forme en plateaux des éléments rigides, atteint encore un coût qu'il serait souhaitable de diminuer.The structure described in this document advantageously makes it possible to fix directly the rigid elements on the frame of the building or smooth metal associated with the framework without the need for fixing means intermediate. However, the structure, by nature in sheet metal and the shape in trays of rigid elements, still achieves a cost that would be desirable to decrease.

Par ailleurs, la performance de l'isolation acoustique du bâtiment est liée, outre à la nature des parois, à l'épaisseur et à la nature du ressort et de l'amortisseur, à la masse surfacique de la structure qui est donnée par la quantité de laine minérale introduite dans l'élément porteur et par la nature en tôle de l'élément porteur. Néanmoins, la masse surfacique est parfois insuffisante, il est alors nécessaire, en vue d'augmenter la performance acoustique, d'ajouter une charge supplémentaire au fond du plateau, par exemple une plaque de plâtre, ce qui augmente encore le prix de revient de la structure.Moreover, the performance of the acoustic insulation of the building is linked, in addition to the nature of the walls, the thickness and the nature of the spring and the damper, to the surface mass of the structure that is given by the quantity of mineral wool introduced into the supporting element and by the sheet metal nature of the carrier element. Nevertheless, the mass per unit area is sometimes insufficient, it is necessary, in order to increase the acoustic performance, to add a additional load at the bottom of the tray, for example a plasterboard, this which further increases the cost price of the structure.

L'invention a par conséquent pour but de fournir une structure acoustique, répondant notamment à une structure du type masse-ressort-masse, qui tout en gardant les avantages d'une isolation acoustique performante et d'une simplification dans ses moyens de fixation à l'ossature du bâtiment, soit diminuée en coût global. The object of the invention is therefore to provide an acoustic structure, responding in particular to a structure of the mass-spring-mass type, which while keeping the advantages of high-performance sound insulation and simplification in its means of attachment to the frame of the building, be decreased in overall cost.

Selon l'invention, la structure acoustique est caractérisée en ce que l'élément porteur consiste en une paire de profilés inférieur et supérieur espacés d'un pas p, qui comprennent chacun, une âme respective en regard l'une de l'autre, et une aile respective pliée perpendiculairement à l'âme associée, les ailes étant dans un même plan et dirigées l'une vers l'autre, et le panneau de laine minérale étant logé entre les âmes des profilés, et l'ensemble acoustique comporte un panneau rigide fixé contre les faces externes des ailes des profilés.According to the invention, the acoustic structure is characterized in that the carrier element consists of a pair of spaced lower and upper profiles of a step p, which each include, a respective soul facing one of the other, and a respective wing bent perpendicular to the associated soul, the wings being in the same plane and directed towards each other, and the woolen panel mineral being housed between the souls of the profiles, and the acoustic assembly comprises a rigid panel fixed against the outer faces of the flanges of the profiles.

Cette structure présente l'avantage d'obtenir directement la masse surfacique suffisante à l'isolation acoustique sans devoir ajouter d'autres épaisseurs d'éléments surfaciques comme c'est généralement le cas pour les plateaux en tôle de l'art antérieur au fond desquels on associe en supplément des panneaux de plâtre.This structure has the advantage of directly obtaining mass sufficient surface area to sound insulation without having to add more thicknesses of surface elements as is generally the case for sheet metal trays of the prior art at the bottom of which is associated in addition to plasterboards.

Selon un premier mode de réalisation des profilés, le profilé supérieur comprend de l'autre côté de l'âme, parallèlement et en direction opposée à l'aile une seconde aile destinée à la fixation de l'ensemble acoustique contre l'ossature du bâtiment.According to a first embodiment of the profiles, the upper profile includes the other side of the soul, parallel and in the opposite direction to the wing a second wing intended for fixing the acoustic assembly against the frame of the building.

Avantageusement, les profilés inférieur et supérieur de ce mode de réalisation comportent des formes complémentaires de façon que le profilé supérieur dudit ensemble coopère avec le profilé inférieur d'un deuxième ensemble acoustique destiné à s'assembler avec ledit premier ensemble acoustique.Advantageously, the lower and upper sections of this mode of embodiment comprise complementary shapes so that the profile upper part of said assembly cooperates with the lower profile of a second acoustic assembly for assembling with said first set acoustic.

Selon un second mode de réalisation des profilés, les profilés inférieur et supérieur sont identiques et comportent chacun parallèlement à l'aile une aile supplémentaire de manière à présenter une section en forme de U telle que les ouvertures du U soient en regard l'une de l'autre et entre lesquelles est coincé le panneau de laine minérale, la fixation de l'ensemble acoustique à l'ossature du bâtiment étant réalisée au moyen d'au moins deux pièces de fixation entre lesquelles sont destinés à être maintenus les profilés et dont au moins une est destinée à être fixée à l'ossature.According to a second embodiment of the profiles, the lower and are identical and each have a wing parallel to the wing to have a U-shaped section such that the openings of the U are facing each other and between which is stuck the mineral wool panel, fixing the acoustic assembly to the frame of the building being made by means of at least two fasteners between which are intended to be maintained the profiles and of which at least one is intended to be fixed to the frame.

Chaque ensemble acoustique 1 comporte un élément porteur 10 métallique, un panneau de laine minérale 20 et un panneau rigide 30 contribuant à la masse de l'ensemble et formé de préférence par une plaque de plâtre.Each acoustic assembly 1 comprises a carrier element 10 a mineral wool panel 20 and a rigid panel 30 contributing to the mass of the assembly and preferably formed by a plasterboard.

Les ensembles acoustiques sont généralement livrés sur le chantier de manière pré-assemblée pour n'avoir à effectuer simplement que les opérations de montage et de fixation à l'ossature du bâtiment. Les dimensions d'un ensemble sont de 400mm de hauteur, de 3,25 à 8 m de longueur, longueur qui est adaptée à la distance séparant deux poteaux de fixation de l'ossature. La largeur d'un ensemble est imposée par la largeur de l'élément porteur 10 et de la plaque de plâtre 30, la largeur des profilés étant adaptée pour recevoir des panneaux de laines minérales d'épaisseur 70 mm, et la plaque de plâtre ayant une épaisseur de 12,5 ou 15, ou encore 18 mm pour réaliser une masse surfacique de l'ensemble acoustique suffisante afin que l'isolation acoustique générale de la structure soit supérieure à 50 dB (A) selon les normes actuelles.Acoustic assemblies are generally delivered to the building site pre-assembled way of simply having to perform only the operations of mounting and fastening to the building frame. The dimensions of a set are 400mm in height, from 3.25 to 8 m in length, which is adapted to the distance separating two posts fixing the frame. The width of a set is imposed by the width of the carrier element 10 and the plate of plaster 30, the width of the profiles being adapted to receive panels of mineral wool 70 mm thick, and the plasterboard having a thickness of 12.5 or 15, or 18 mm to achieve a total mass per unit area sufficient acoustics to ensure that the overall sound insulation of the structure is greater than 50 dB (A) according to current standards.

L'élément porteur 10 d'un ensemble acoustique 1 consiste en une paire de profilés inférieur 11 et supérieur 12 situés dans un même plan et écartés d'un pas p, et entre lesquels est agencé le panneau de laine minérale 20. Les profilés inférieur 11 et supérieur 12 comportent, respectivement, une âme 13 et une âme 14 en regard l'une de l'autre, ainsi qu'une aile 15 et une aile 16 perpendiculaires à l'âme associée et dirigées l'une vers l'autre.The carrier element 10 of an acoustic assembly 1 consists of a pair of lower 11 and upper 12 profiles located in the same plane and spaced a step p, and between which is arranged the mineral wool panel 20. The profiles lower 11 and upper 12 comprise, respectively, a soul 13 and a soul 14 facing each other, as well as a wing 15 and a wing 16 perpendicular to the soul associated and directed towards each other.

L'invention distingue deux modes de réalisation de l'ensemble acoustique 1 selon la forme des profilés, engendrant d'ailleurs deux systèmes distincts de fixation à l'ossature du bâtiment.The invention distinguishes two embodiments of the acoustic assembly 1 depending on the shape of the profiles, generating two separate systems of fastening to the frame of the building.

Dans un premier mode de réalisation (figure 1), le profilé inférieur 11 comporte à l'opposé de l'aile 15, de l'autre côté de l'âme 13, une aile 15a parallèle à l'autre aile et de même direction de manière à former une section en U à l'intérieur de laquelle peut être maintenu coincé le panneau de laine minérale 20. En prolongement de l'aile 15a et à l'opposé de son extrémité libre 15b, le profilé 11 est pourvu d'un bandeau longitudinal d'assemblage 17 destiné, comme on le verra par la suite, à coopérer avec un autre ensemble acoustique 1.In a first embodiment (FIG. 1), the lower profile 11 has opposite the wing 15, on the other side of the core 13, a wing 15a parallel to the other wing and of the same direction so as to form a U-shaped section to the interior of which can be kept stuck the mineral wool panel 20. In extension of the wing 15a and opposite its free end 15b, the profile 11 is provided with a longitudinal assembly strip 17 intended, as it is will see later, to cooperate with another acoustic set 1.

Le profilé supérieur 12 du premier mode de réalisation comporte de l'autre côté de l'âme 14 une autre aile 16a parallèle mais de direction opposée à l'aile 16. Cette aile 16a est reliée à l'âme 14 par une gorge 18, à concavité tournée vers la direction opposée au profilé inférieur, et dont le fond est dans un plan parallèle et situé en-dessous du plan contenant l'âme 14. La surface latérale 16b qui sépare le fond de la gorge 18 de l'âme 14 participe au maintien du panneau de laine minérale 20 inséré entre les deux profilés.The upper profile 12 of the first embodiment comprises of the other side of the core 14 another wing 16a parallel but opposite direction to the wing 16. This wing 16a is connected to the core 14 by a groove 18, concavity turned towards the direction opposite to the lower profile, and whose bottom is in a parallel plane and located below the plane containing the core 14. The lateral surface 16b which separates the bottom of the throat 18 of the soul 14 participates in the maintenance of the woolen panel mineral 20 inserted between the two sections.

Comme illustré à la figure 6, la gorge 18 du profilé 12 d'un premier ensemble acoustique est destinée à accueillir le bandeau d'assemblage 17 d'un profilé inférieur 11 d'un autre ensemble acoustique destiné à être monté au-dessus du premier ensemble, l'âme 13 du profilé inférieur 11 du second ensemble reposant sur l'âme 14 du profilé supérieur 12 du premier ensemble. As illustrated in FIG. 6, the groove 18 of the profile 12 of a first acoustic assembly is intended to accommodate the assembly strip 17 of a lower profile 11 of another acoustic assembly intended to be mounted above of the first set, the core 13 of the lower profile 11 of the second set resting on the core 14 of the upper profile 12 of the first set.

Le panneau de laine minérale 20 est inséré, coincé et éventuellement collé entre les deux profilés inférieur 11 et supérieur 12 contre les âmes 13 et 14, les parois des ailes 15, 15a et 16 et la surface latérale 16b.The mineral wool panel 20 is inserted, jammed and possibly glued between the two lower profiles 11 and upper 12 against the webs 13 and 14, the wings walls 15, 15a and 16 and the side surface 16b.

Le panneau rigide 30, ou la plaque de plâtre, est quant à lui agencé contre la face externe des ailes 15 et 16 des profilés et présente une hauteur telle que ses bords inférieur 31 et supérieur 32 soient coplanaires avec les âmes 13 et respectivement 14 des profilés.The rigid panel 30, or the plasterboard, is in turn arranged against the outer face of the wings 15 and 16 of the profiles and has a height such that its lower 31 and upper 32 edges are coplanar with the souls 13 and respectively 14 profiles.

La fixation du panneau 30 est réalisée par tous moyens connus, tels que par collage, vissage ou encore cloutage.The fixing of the panel 30 is carried out by any known means, such as by gluing, screwing or nailing.

Selon ce premier mode de réalisation, l'ensemble acoustique 1 est fixé aux poteaux 40 par le profilé supérieur 12, proche de l'extrémité libre 16c de l'aile 16a, par tous moyens de fixation connus tels des vis autotaraudeuses.According to this first embodiment, the acoustic assembly 1 is fixed to posts 40 by the upper section 12, near the free end 16c of the wing 16a, by any known fastening means such as self-tapping screws.

L'aile 16a du profilé supérieur présente une hauteur supérieure à celle de l'aile 15a d'un profilé inférieur de manière que les moyens de fixation agencés vers l'extrémité supérieure 16c soient suffisamment hauts pour ne pas gêner, lors de la mise en place d'un second ensemble acoustique sur un premier ensemble, l'application de l'aile 15a du profilé inférieur du second ensemble contre l'aile 16a du profilé supérieur du premier ensemble tandis que le bandeau d'assemblage 17 est emboíté dans la gorge 18.The wing 16a of the upper profile has a height greater than that of the wing 15a of a lower profile so that the fastening means arranged towards the upper end 16c are high enough not to interfere, during the setting up a second acoustic set on a first set, the application of the wing 15a of the lower section of the second assembly against the wing 16a the upper profile of the first set while the assembly strip 17 is nested in the throat 18.

Dans le second mode de réalisation de l'invention (figure 2), il s'agit d'utiliser comme éléments porteurs 10, des profilés inférieur 11 et supérieur 12 identiques du commerce dont la section présente une forme en U, les profilés comportant parallèlement à l'aile 15 et respectivement à l'aile 16, de l'autre côté de l'âme, des ailes 19, les ouvertures des U étant en regard l'une de l'autre pour permettre le logement du panneau 20 entre les deux profilés.In the second embodiment of the invention (FIG. to use as bearing elements 10, lower sections 11 and upper 12 identical with the U-shaped cross-section, the profiles having parallel to the wing 15 and respectively to the wing 16, on the other side of the soul, wings 19, the openings of the U being opposite one another to allow the housing of the panel 20 between the two sections.

Le panneau rigide 30 constitué par une plaque de plâtre est fixé contre la face externes des ailes 15 et 16 des profilés inférieur et respectivement supérieur, sa hauteur étant adaptée de sorte que ses bords inférieur 31 et supérieur 32 soient coplanaires avec les âmes 13 et 14 des profilés.The rigid panel 30 constituted by a plasterboard is fixed against the external faces of the wings 15 and 16 of the lower and respectively upper profiles, its height being adapted so that its lower edges 31 and upper 32 are coplanar with the cores 13 and 14 of the profiles.

Pour la fixation à l'ossature du bâtiment de l'ensemble acoustique réalisé selon ce second mode, il est prévu des pièces de fixation inférieure 50 (figure 4) et intermédiaire 60 (figure 5). En variante, la pièce intermédiaire 60 peut être remplacée par une pièce identique à celle de fixation inférieure 50. For fixing to the building frame of the acoustic ensemble realized according to this second mode, lower fasteners 50 are provided (FIG. 4) and intermediate 60 (FIG. 5). Alternatively, the intermediate part 60 can be replaced by a piece identical to that of the lower attachment 50.

Dans la première variante, la pièce inférieure 50 n'est utilisée que pour la fixation du premier ensemble acoustique devant être disposé près du sol, la pièce inférieure 50 coopérant avec le profilé inférieur 11. La pièce intermédiaire 60 joue le rôle de moyen de fixation des ensembles acoustiques montés au-dessus du premier ensemble, la pièce intermédiaire 60 coopérant d'une part avec le profilé supérieur 12 du premier ensemble, et d'autre part avec les profilés inférieur et supérieur des autres ensembles disposés au-dessus.In the first variant, the lower part 50 is only used for the fixation of the first acoustic unit to be arranged near the floor, the room lower 50 cooperating with the lower profile 11. The intermediate part 60 plays the role of fastening means of acoustic assemblies mounted above the first set, the intermediate piece 60 cooperating on the one hand with the profile 12 of the first set, and on the other hand with the lower and superior of the other sets arranged above.

La pièce de fixation inférieure 50 comporte une âme 51 et, de chaque côté de cette âme et perpendiculairement à celle-ci, une aile de fixation 52 et une aile de maintien 53, toutes deux en regard l'une de l'autre. La largeur de l'âme 51 est sensiblement supérieure à la largeur d'un ensemble acoustique.The lower fastener 50 has a core 51 and on each side of this soul and perpendicular thereto, a fixing wing 52 and a wing 53, both facing each other. The width of the soul 51 is substantially greater than the width of an acoustic assembly.

Comme illustré à la figure 7, la pièce 50 est destinée à être montée en premier lieu pour recevoir le premier ensemble acoustique. Ainsi, l'aile de fixation 52 est destinée à être montée par sa face externe contre l'ossature du bâtiment, les faces internes de l'aile de fixation 52, de l'âme 51 et de l'aile de maintien 53 étant destinées à recevoir en appui, respectivement, l'aile 15, l'âme 13 du profilé inférieur 11 et la face externe de la plaque de plâtre 30. L'aile de fixation 52 est suffisamment haute pour que ses moyens de fixation à l'ossature ne gênent pas l'application de l'aile 15 du profilé contre elle.As illustrated in FIG. 7, the part 50 is intended to be mounted in first place to receive the first acoustic set. Thus, the fixing wing 52 is intended to be mounted by its outer face against the frame of the building, the inner faces of the fastening flange 52, the core 51 and the holding flange 53 being intended to support, respectively, the wing 15, the core 13 of the profile 11 and the outer face of the plasterboard 30. The fastening flange 52 is high enough that its means of attachment to the frame do not interfere the application of the wing 15 of the profile against it.

La pièce de fixation intermédiaire 60 présente une section en forme de I. Elle comporte une surface de fixation 61 et une surface de retenue 62 parallèle à la surface de fixation et reliée à celle-ci par une surface de liaison 63 dont la largeur est sensiblement supérieure à celle d'un ensemble acoustique. La surface de liaison 63 délimite un canal supérieur de logement 60a et un canal inférieur de logement 60b.The intermediate fastener 60 has an I-shaped section. It comprises a fixing surface 61 and a retaining surface 62 parallel to the attachment surface and connected thereto by a connecting surface 63 whose width is substantially greater than that of an acoustic assembly. The surface link 63 delimits an upper housing channel 60a and a lower channel of housing 60b.

Comme illustré à la figure 7, la surface de fixation 61 est destinée à être montée contre l'ossature du bâtiment tandis que la surface de liaison 63 est destinée à recevoir en appui l'âme 14 du profilé supérieur du premier ensemble acoustique et l'âme 13 du profilé inférieur d'un second ensemble acoustique destiné à être placé au-dessus du premier ensemble, et la surface de retenue 62 est destinée à assurer le maintien en position des deux ensembles par l'appui contre celle-ci des plaques de plâtre 30 desdits ensembles.As illustrated in FIG. 7, the fixing surface 61 is intended to be mounted against the building frame while the connecting surface 63 is intended to receive in support the core 14 of the upper profile of the first set acoustic and the core 13 of the lower profile of a second acoustic assembly intended to be placed above the first set, and the retaining surface 62 is intended to ensure that the two sets are held in position by the support against this one gypsum board 30 of said sets.

Dans la seconde variante du second mode de réalisation qui est illustrée à la figure 8, la fixation se fait au moyen de pièces 50 identiques en forme d'équerre. Le montage d'une pièce sur le profilé supérieur d'un ensemble acoustique est réalisé en fixant par vis par exemple l'aile de fixation 52 à l'ossature du bâtiment et l'âme 51 à l'âme 14 du profilé.In the second variant of the second embodiment which is illustrated in Figure 8, the attachment is made by means of identical pieces 50 in the form of a square. The mounting of a part on the upper section of an acoustic assembly is realized by fixing by screw for example the fixing flange 52 to the frame of the building and the core 51 to the core 14 of the profile.

Nous allons à présent décrire le montage et la fixation d'une face d'une structure acoustique selon les deux modes de réalisation distincts des éléments porteurs.We will now describe the mounting and fixing of a face of a acoustic structure according to the two distinct embodiments of the elements carriers.

Afin d'isoler toute une paroi du bâtiment du sol au plafond, il est fixé en partant du sol, entre au moins deux poteaux de l'ossature, plusieurs ensembles acoustiques 1 les uns au-dessus des autres.In order to insulate an entire wall of the building from floor to ceiling, it is fixed in from the ground, between at least two studs of the frame, several sets acoustic 1 on top of each other.

La figure 6 illustre deux ensembles acoustiques selon le premier mode de réalisation une fois montés et fixés.Figure 6 illustrates two acoustic sets according to the first mode of realization once mounted and fixed.

Le premier ensemble acoustique 1 est positionné pour reposer sur une semelle en bois 1a fixée au sol et est maintenu plaqué contre l'ossature en clouant un tasseau de bois 1b à la semelle 1a. Le premier ensemble est ensuite fixé aux poteaux de l'ossature 40 par solidarisation de l'aile 16a du profilé supérieur au niveau de son extrémité supérieure 16c au moyen de vis 41.The first acoustic assembly 1 is positioned to rest on a wooden sole 1a fixed to the ground and is kept pressed against the frame by nailing a wooden batten 1b to the sole 1a. The first set is then set at posts of the frame 40 by joining the wing 16a of the upper profile to the level of its upper end 16c by means of screws 41.

Un deuxième ensemble acoustique 1 est ensuite monté au-dessus du premier ensemble. On engage d'abord le bandeau d'assemblage 17 du profilé inférieur 11 dans la gorge 18 du profilé supérieur 12 du premier ensemble déjà fixé, puis on bascule ledit ensemble vers l'ossature du bâtiment de manière à emboíter le bandeau dans la gorge, à asseoir l'âme 13 du profilé inférieur sur l'âme 14 du profilé supérieur du premier ensemble, et à plaquer l'ensemble contre les poteaux. Enfin, on fixe ce deuxième ensemble en vissant l'aile 16a du profilé supérieur aux poteaux.A second acoustic assembly 1 is then mounted above the first set. The assembly strip 17 of the profile is first engaged lower 11 in the groove 18 of the upper profile 12 of the first set already fixed, and then rocking said assembly to the frame of the building so as to fit the strip in the groove, to seat the core 13 of the lower profile on the core 14 of the upper profile of the first set, and to press the assembly against poles. Finally, this second assembly is fixed by screwing the wing 16a of the profile higher than the poles.

La figure 7 illustre deux ensembles acoustiques une fois montés et fixés selon le second mode de réalisation et selon la première variante de ce mode.Figure 7 illustrates two acoustic assemblies once mounted and fixed according to the second embodiment and according to the first variant of this mode.

Deux pièces 50 sont d'abord fixées par leur aile 52, respectivement, sur deux poteaux alignés de l'ossature 40 du bâtiment, les pièces reposant sur le sol par la face externe de leur âme 51. L'ensemble acoustique 1 est alors logé par coincement dans les pièces de fixation 50. L'ensemble est maintenu en position verticale pour éviter tout basculement par les ailes 53 des pièces 50. L'ensemble est fixé à l'ossature au moyen de deux pièces intermédiaires de fixation 60 qui sont montées sur la tranche supérieure de l'ensemble au niveau des deux poteaux. La partie inférieure de la surface de fixation 61 est insérée entre un poteau et l'aile 16 du profilé supérieur, la surface de retenue 62 présente sa partie inférieure plaquée contre la plaque de plâtre 30 du premier ensemble et la surface de liaison 63 repose sur l'âme 14 du profilé supérieur, le canal inférieur 60b de la pièce coiffant ainsi une partie de la tranche supérieure de l'ensemble acoustique. La partie supérieure 61 a de la surface de fixation 61 est ensuite fixée par vissage au poteau associé pour fixer la pièce et maintenir fermement coincé ledit ensemble.Two pieces 50 are first fixed by their wing 52, respectively, on two aligned columns of the frame 40 of the building, the rooms resting on the ground by the outer face of their core 51. The acoustic assembly 1 is then housed by jamming in the fasteners 50. The assembly is held in position vertical to prevent tilting by the wings 53 of the pieces 50. The set is fixed to the framework by means of two intermediate fixing pieces 60 which are mounted on the upper edge of the set at the level of both posts. The lower part of the attachment surface 61 is inserted between a post and the flange 16 of the upper profile, the retaining surface 62 has its part lower pressed against the plasterboard 30 of the first set and the surface connection 63 rests on the core 14 of the upper profile, the lower channel 60b of the piece thus capping a portion of the upper edge of the acoustic assembly. The upper portion 61a of the fastening surface 61 is then screwed together to the associated post to fix the piece and hold firmly stuck said together.

Le canal supérieur 60a des pièces de fixation servira de logement d'accueil à un deuxième ensemble, l'âme 13 du profilé inférieur 11 de cet ensemble reposant sur les surfaces de liaison 63 des pièces. De la même manière que pour la fixation du premier ensemble, on rapporte deux pièces 60 sur le dessus du second ensemble, la tranche supérieure de l'ensemble étant logée dans le canal inférieur 60b des nouvelles pièces, puis on fixe ces pièces par leur surface 61 aux poteaux afin de fixer le second ensemble acoustique.The upper channel 60a of the fasteners will serve as a home to a second assembly, the core 13 of the lower section 11 of this assembly resting on the connecting surfaces 63 of the parts. In the same way as for fixing the first set, we report two pieces 60 on top of the second set, the upper edge of the assembly being housed in the channel lower 60b of the new parts, then we fix these parts by their surface 61 to poles in order to fix the second acoustic set.

Notons que les faces externes des surfaces de retenue 62 des pièces 60 et des ailes 53 des pièces 50 peuvent servir de supports de fixation à un parement d'ornement destiné à couvrir les plaques de plâtre 30.Note that the outer faces of the retaining surfaces 62 of the parts 60 and wings 53 of the parts 50 can serve as support for fixing a facing ornament for covering plasterboard 30.
