Description

Cloison réalisée à partir de panneaux, notamment de plâtre. Partition made from panels, including plaster.
La présente invention concerne une cloison réalisée à partir de panneaux, notamment de plâtre.The present invention relates to a partition made from panels, including plaster.
Ce type de cloison est essentiellement utilisé pour réaliser des cloisons de séparation entre différentes pièces de bâtiments de type habitat, bureaux ou établissements publics divers.This type of partition is mainly used to make partition walls between different parts of buildings of housing type, offices or various public institutions.
Ces cloisons comprennent habituellement une ossature métallique constituée d'un profilé métallique inférieur fixé au sol et d'un profilé métallique supérieur fixé au plafond à la verticale du profilé inférieur. Dans ces profilés sont fixés des montants verticaux d'entraxe variant entre 0,3 et 0,6 mètre. Les profilés métalliques mis en œuvre possèdent une section en U.These partitions usually comprise a metal frame consisting of a lower metal profile fixed to the ground and an upper metal profile fixed to the ceiling vertically of the lower profile. In these profiles are fixed vertical uprights spacing between 0.3 and 0.6 meters. The metal profiles used have a U-section.
De part et d'autre de cette ossature métallique sont fixés sur celle- ci des panneaux, notamment des panneaux de plaques de plâtre cartonnées, c'est-à-dire comportant une âme en plâtre revêtue sur au moins l'une de ses faces d'un carton ou des panneaux de plaques de plâtre fibreux.On both sides of this metal frame are fixed thereto panels, including panels gypsum boards, that is to say having a plaster core coated on at least one of its faces cardboard or fibrous drywall panels.
Les deux séries de panneaux fixés de part et d'autre de l'ossature délimitent un espace. Afin d'améliorer les performances de la cloison, cet espace contient un élément absorbant acoustique tel que des panneaux de laine minérale. Cependant, l'utilisation de panneaux de laine minérale présente de nombreux inconvénients.The two series of panels fixed on either side of the frame delimit a space. In order to improve the performance of the partition, this space contains an acoustic absorbing element such as mineral wool panels. However, the use of mineral wool panels has many disadvantages.
Un premier inconvénient des panneaux de laine minérale réside dans le fait que la laine minérale crée une résistance thermique.A first disadvantage of mineral wool panels lies in the fact that mineral wool creates a thermal resistance.
Cette résistance thermique peut avoir pour conséquence d'isoler thermiquement deux locaux, ce qui n'est pas toujours recherché.This thermal resistance can have the effect of thermally isolating two premises, which is not always sought.
Mais ce qui est plus important, c'est que cette résistance thermique amoindrit la tenue au feu des cloisons.But what is more important is that this thermal resistance reduces the fire resistance of the partitions.
En effet, en cas d'incendie, la laine minérale accumule la chaleur dégagée par l'incendie, ce qui a pour conséquence une dégradation de l'ossature métallique et donc de la cloison.Indeed, in case of fire, the mineral wool accumulates the heat released by the fire, which results in a degradation of the metal frame and therefore the partition.
D'autres inconvénients des panneaux de laine minérale consistent en ce qu'ils sont volumineux, lourds et encombrants, ce qui rend donc difficile leur stockage, leur transport et leur pose.Other disadvantages of mineral wool panels are that they are bulky, heavy and bulky, which makes it difficult to store, transport and install.
Ces différents inconvénients conduisent les fabriquant à ne plus placer des panneaux de laine minérale dans l'espace délimité par les séries de panneaux de plâtre. II en résulte un affaiblissement de 5dB de la valeur de l'indice d'affaiblissement acoustique de la cloison par rapport aux cloisons comportant des panneaux de laine minérale.These various disadvantages lead the manufacturers to no longer place mineral wool panels in the space delimited by the series of plasterboards. This results in a 5 dB loss of the value of the sound attenuation index of the partition compared to the partitions comprising mineral wool panels.
De ce fait, l'isolation acoustique entre les locaux délimités par cette cloison n'est plus satisfaisante.As a result, the acoustic insulation between the rooms delimited by this partition is no longer satisfactory.
La présente invention vise donc à remédier à ces inconvénients.The present invention therefore aims to remedy these drawbacks.
Le problème technique à la base de l'invention est la réalisation d'une cloison réalisée à partir de panneaux, notamment de plâtre, comprenant un matériau absorbant acoustique, qui soit de structure simple, de mise en œuvre rapide, qui puisse être stocké et mis en œuvre sous un faible volume, et qui crée une résistance thermique faible et qui assure le maintien d'une valeur satisfaisante de l'indice d'affaiblissement acoustique de la cloison sur tout le spectre acoustique.The technical problem underlying the invention is the production of a partition made from panels, especially plaster, comprising an acoustic absorbent material, which is simple in structure, fast implementation, which can be stored and implemented under a small volume, and which creates a low thermal resistance and which ensures the maintenance of a satisfactory value of the sound reduction index of the partition over the entire acoustic spectrum.
A cet effet, l'invention concerne une cloison réalisée à partir de panneaux, notamment de plâtre, comprenant une ossature métallique de part et d'autre de laquelle sont fixés des panneaux, notamment des panneaux de plaques de plâtre, les deux séries de panneaux fixés de part et d'autre de l'ossature délimitant un espace, cet espace contenant un élément absorbant acoustique, caractérisée en ce que l'élément absorbant acoustique est constitué par un tissu de verre réalisé à partir de fils de verre enduits de matière thermoplastique, avec un facteur d'ouverture compris entre 0,5 et 6%.For this purpose, the invention relates to a partition made from panels, including plaster, comprising a metal frame on either side of which are fixed panels, including plasterboard panels, the two series of panels fixed on either side of the framework delimiting a space, this space containing an acoustic absorbing element, characterized in that the acoustic absorbing element consists of a glass fabric made from thermoplastic-coated glass fibers , with an opening factor of between 0.5 and 6%.
L'utilisation du tissu absorbant acoustique décrit ci-dessus à la place des panneaux de laine minérale utilisés dans l'art antérieur permet d'éviter la création d'une importante résistance thermique de la cloison, ce qui évite de créer une isolation thermique entre les locaux formés par la cloison ainsi que d'engendrer une dégradation de l'ossature métallique suite à une forte chaleur dégagée par un feu.The use of the acoustic absorbent fabric described above instead of the mineral wool panels used in the prior art avoids the creation of a significant thermal resistance of the partition, which avoids creating thermal insulation between the premises formed by the partition as well as to cause degradation of the metal frame following a strong heat released by a fire.
En outre, le tissu possède une faible épaisseur et un faible poids, ce qui réduit son encombrement et facilite son transport et sa pose. De plus, l'expérience montre que la présence du tissu dans . la cloison assure, selon sa position dans celle-ci, une augmentation de 3 à 4 dB de la valeur de l'indice d'affaiblissement acoustique sur tout le spectre acoustique.In addition, the fabric has a small thickness and low weight, which reduces its size and facilitates its transport and its installation. In addition, experience shows that the presence of tissue in. the partition ensures, according to its position in it, an increase of 3 to 4 dB of the value of the sound reduction index over the entire acoustic spectrum.
De ce fait, le tissu selon l'invention permet d'obtenir quasiment les mêmes avantages que les panneaux de laine minérale utilisés dans les cloisons de l'art antérieur tout en évitant leurs nombreux désavantages. Avantageusement, le tissu est fixé dans la cloison de façon à être à distance des panneaux sur au moins une partie de sa surface.As a result, the fabric according to the invention makes it possible to obtain almost the same advantages as the mineral wool panels used in the partitions of the prior art while avoiding their numerous disadvantages. Advantageously, the fabric is fixed in the partition so as to be at a distance from the panels on at least part of its surface.
Cette position du tissu permet une bonne absorption acoustique, car la membrane formée par le tissu peut ainsi vibrer avec peu de contraintes. Selon une première alternative de l'invention, l'ossature métallique comprend une profilé métallique inférieur fixé au sol et un profilé métallique supérieur fixé au plafond à la verticale du profilé inférieur, des montants sensiblement verticaux et espacés étant fixés sur ces profilés, et le tissu absorbant acoustique est fixé alternativement entre un montant et la première série de panneaux et entre un montant adjacent et la seconde série de panneaux.This position of the fabric allows a good sound absorption, because the membrane formed by the fabric can thus vibrate with few constraints. According to a first alternative of the invention, the metal frame comprises a lower metal profile fixed to the ground and an upper metal profile fixed to the ceiling vertically to the lower profile, substantially vertical and spaced amounts being fixed on these profiles, and the Acoustic absorbent fabric is alternately fixed between an upright and the first series of panels and between an adjacent upright and the second series of panels.
Selon une seconde alternative de l'invention, l'ossature métallique comprend deux séries de montants verticaux délimitant un espace entre elles, le tissu absorbant acoustique étant fixé sur la première série de montants ou sur la seconde série de montants, ou alternativement sur la première et sur la seconde séries de montants.According to a second alternative of the invention, the metal frame comprises two series of vertical uprights delimiting a space between them, the acoustic absorbent fabric being fixed on the first series of uprights or on the second series of uprights, or alternatively on the first and on the second set of amounts.
Avantageusement, la taille et la forme des trous du tissu absorbant acoustique sont déterminées pour obtenir un coefficient d'absorption acoustique αw sabine avec plénum de 10 cm compris entre 0,3 et 0,8, en fonction de la fréquence des sons.Advantageously, the size and the shape of the holes of the acoustic absorbent fabric are determined to obtain a sound absorption coefficient αw sabine plenum of 10 cm between 0.3 and 0.8, depending on the frequency of sounds.
Cette forme et le facteur d'ouverture des trous peuvent être obtenus directement à l'issue du tissage. Le tissu est avantageusement soumis à un traitement thermique, sans contrainte, qui permet de bloquer les fils. Il est également possible de mettre en œuvre une opération de calandrage, d'un tissu de facteur d'ouverture plus élevé, pour réduire le facteur d'ouverture à la valeur souhaitée.This shape and the opening factor of the holes can be obtained directly after weaving. The fabric is advantageously subjected to a heat treatment, without stress, which makes it possible to block the threads. It is also possible to implement a calendering operation, with a higher aperture factor fabric, to reduce the aperture factor to the desired value.
La réduction du facteur d'ouverture peut également être obtenue en soumettant l'une au moins des faces du tissu à une enduction d'un liant transparent ou coloré. Suivant une autre caractéristique de l'invention, le diamètre des fils de verre est compris entre 150 et 600 microns et de préférence entre 270 et 400 micronsThe reduction of the opening factor can also be achieved by subjecting at least one of the faces of the fabric to a coating of a transparent or colored binder. According to another characteristic of the invention, the diameter of the glass strands is between 150 and 600 microns and preferably between 270 and 400 microns.
En outre, le titre des fils de verre seuls est compris entre 22 et 136 tex de préférence entre 34 et 68 tex, et le titre des fils enduits de matière thermoplastique est compris entre 60 et 200 tex et de préférence entre 95 et 165 tex. De toute façon l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, deux variantes d'exécution de cette cloison.In addition, the title of the glass son alone is between 22 and 136 tex, preferably between 34 and 68 tex, and the title of the son coated with thermoplastic material is between 60 and 200 tex and preferably between 95 and 165 tex. In any case the invention will be better understood with the aid of the description which follows with reference to the attached schematic drawing showing, by way of non-limiting example, two variants of this partition.
Figure 1 est une vue de face d'une d'ossature métallique sur laquelle est fixé un tissu absorbant acoustique.Figure 1 is a front view of a metal frame on which is fixed an acoustic absorbent fabric.
Figure 2 est une vue en coupe d'une cloison selon une première variante d'exécution de l'invention, la cloison comprenant l'ossature métallique de la figure 1.Figure 2 is a sectional view of a partition according to a first embodiment of the invention, the partition comprising the metal frame of Figure 1.
Figure 3 est une vue en coupe d'une cloison selon une seconde variante d'exécution de l'invention.Figure 3 is a sectional view of a partition according to a second embodiment of the invention.
La figure 2 représente une cloison 2 réalisée à partir de panneaux de plâtre.Figure 2 shows a partition 2 made from plasterboards.
Comme représenté plus particulièrement à la figure 1 , la cloison 2 comprend une ossature métallique 3 constituée d'un profilé métallique inférieur 4 fixé au sol et d'un profilé métallique supérieur 5 fixé au plafond à la verticale du profilé inférieur 4. Les profilés métalliques encore appelés rails mis en œuvre possèdent avantageusement une section en U.As shown more particularly in Figure 1, the partition 2 comprises a metal frame 3 consisting of a lower metal profile 4 fixed to the ground and an upper metal profile 5 fixed to the ceiling vertically lower profile 4. The metal profiles still called rails used advantageously have a section U.
Dans ces profilés sont fixés des montants verticaux 6 d'entraxe constant, les montants 6 étant fixés aux profilés métalliques supérieur et inférieur au niveau de leurs extrémités, par exemple par vissage.In these profiles are fixed uprights 6 of constant spacing, the uprights 6 being fixed to the upper and lower metal sections at their ends, for example by screwing.
Comme montré à la figure 2, les montants 6 intérieurs, c'est-à-dire ceux qui ne sont pas fixés aux murs porteurs du bâtiment, sont constitués de deux profilés en U placés dos à dos et fixés l'un à l'autre, tandis que les montants extérieurs (non montrés sur les figures), c'est-à-dire ceux fixés au murs porteurs du bâtiment ou à une paroi d'extrémité, ne sont constitués que d'un seul profilé en U dont la base est fixée au mur respectif.As shown in Figure 2, the uprights 6 interior, that is to say those that are not attached to the load-bearing walls of the building, consist of two U-shaped sections placed back to back and fixed one to the other, while the external uprights (not shown in the figures), that is to say those attached to the load-bearing walls of the building or to an end wall, consist of only one U-shaped section whose base is attached to the respective wall.
Selon d'autres formes d'exécutions de l'invention, les montants intérieurs 6 peuvent être constitués respectivement d'un profilé en H, et les profilés métalliques supérieur et inférieur peuvent être constitués respectivement d'une succession de profilés métalliques supérieurs et inférieurs de plus petites longueurs.According to other embodiments of the invention, the inner uprights 6 may consist respectively of an H-profile, and the upper and lower metal profiles may consist respectively of a succession of upper and lower metal profiles of smaller lengths.
Comme montré aux figures 1 et 2, un tissu absorbant acoustique 7 est fixé sur l'ossature métallique 3. Le tissu absorbant acoustique 7 est fixé, à l'aide de vis autotaraudeuses (non représentées au dessin) sur les différents montants 6, alternativement sur une première face d'un montant 6 et sur une seconde face, opposée à la première face, d'un montant adjacent. Le tissu absorbant acoustique 7 est constitué par un tissu de verre réalisé à partir de fils de verre enduits de matière thermoplastique, avec un facteur d'ouverture compris entre 0,5 et 6%.As shown in FIGS. 1 and 2, an acoustic absorbent fabric 7 is fixed on the metal frame 3. The acoustic absorbent fabric 7 is fixed, using self-tapping screws (not shown in the drawing) on the various uprights 6, alternatively on a first face of an amount 6 and on a second face, opposite to the first face, an adjacent amount. Acoustic absorbent fabric 7 consists of a glass fabric made from thermoplastic-coated glass yarns, with an opening factor of between 0.5 and 6%.
Comme montré à la figure 2, de part et d'autre de l'ossature métallique 3 sont fixés sur celle-ci des panneaux de plaques de plâtre 8, c'est- à-dire comportant une âme en plâtre 9 revêtue sur ses deux faces d'un carton 10.As shown in Figure 2, on either side of the metal frame 3 are fixed thereto plasterboard panels 8, that is to say having a plaster core 9 coated on both faces of a carton 10.
Les deux séries de panneaux fixés de part et d'autre de l'ossature métallique 3 délimitent ainsi un espace contenant le tissu absorbant acoustique 7.The two series of panels fixed on either side of the metal frame 3 thus delimit a space containing the acoustic absorbent fabric 7.
Comme montré à la figure 2, le tissu absorbant acoustique 7 est donc fixé sur les différents montants 6, alternativement entre un montant 6 et la première série de panneaux de plaques de plâtre 8 et entre un montant adjacent 6 et la seconde série de panneaux de plaques de plâtre 8. La figure 3 représente une seconde variante d'exécution de l'invention.As shown in FIG. 2, the acoustic absorbent fabric 7 is thus fixed on the various uprights 6, alternatively between an upright 6 and the first series of gypsum board panels 8 and between an adjacent upright 6 and the second series of gypsum panels. Plasterboard 8. Figure 3 shows a second embodiment of the invention.
Selon cette variante d'exécution, les mêmes éléments portent les mêmes références numériques que précédemment.According to this alternative embodiment, the same elements bear the same numerical references as before.
Dans ce cas, l'ossature métallique 3 comprend une première et une seconde séries 11 , 12 de montants verticaux 6 délimitant un espace entre elles, cet espace contenant le tissu absorbant acoustique 7.In this case, the metal frame 3 comprises a first and a second series 11, 12 of vertical uprights 6 delimiting a space between them, this space containing the acoustic absorbent fabric 7.
Comme montré sur la figure 3, le tissu absorbant acoustique 7 est dans ce cas fixé sur la même face de chaque montant 6 appartenant à la première série 11 de montants. Selon une autre forme d'exécution de l'invention, le tissu absorbant acoustique 7 peut être fixé sur la seconde série 12 de montants 6 ou alternativement sur la première et sur la seconde séries de montants.As shown in Figure 3, the acoustic absorbent fabric 7 is in this case fixed on the same face of each upright 6 belonging to the first series 11 of uprights. According to another embodiment of the invention, the acoustic absorbent fabric 7 may be attached to the second series 12 of uprights 6 or alternatively to the first and second series of uprights.
Il est donné ci-après deux exemples de tissu absorbant acoustique, obtenu à partir de fils de verre présentant les caractéristiques précédentes, permettant d'obtenir une valeur d'indice d'affaiblissement acoustique satisfaisante :Two examples of acoustic absorbent fabric obtained from glass threads having the above characteristics are given below, making it possible to obtain a satisfactory sound reduction index value:

Coefficient αw sabine : 0,6 Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant une cloison comprenant un matériau absorbant acoustique, qui est de structure simple, de mise en œuvre rapide, qui peut être stocké et mis en œuvre sous un faible volume, et qui crée une résistance thermique faible et qui assure une valeur satisfaisante de l'indice d'affaiblissement acoustique de la cloison sur tout le spectre acoustique.Coefficient αw sabine: 0.6 As can be seen from the foregoing, the invention brings a great improvement to the existing technique by providing a partition comprising an acoustic absorbing material, which is of simple structure, of rapid implementation, which can be stored and implemented in a low volume, and which creates a low thermal resistance and which ensures a satisfactory value of the sound reduction index of the partition over the entire acoustic spectrum.
Comme il va de soi l'invention ne se limite pas à la variante d'exécution de cette cloison décrite ci-dessus à titre d'exemple, elle embrasse au contraire toutes les variantes de réalisation. C'est ainsi notamment que les plaques pourraient être réalisées en un matériau autre que du plâtre sans sortir du cadre de l'invention. C'est ainsi notamment que les montants supportant les panneaux pourraient avoir une forme différente sans que l'on sorte pour autant du cadre de l'invention. As goes without saying the invention is not limited to the variant embodiment of this partition described above by way of example, it embraces on the contrary all variants. This is particularly the fact that the plates could be made of a material other than plaster without departing from the scope of the invention. In particular, the amounts supporting the panels could have a different shape without departing from the scope of the invention.
