Description
BARRIERE PHONIQUE SOUPLE
La présente invention a pour objet une barrière phonique souple.FLEXIBLE PHONIC BARRIER
The present invention relates to a flexible sound barrier.
Elle est destinée au secteur du bâtiment, et plus particulièrement des immeubles de bureaux.It is intended for the building sector, and more particularly for office buildings.
Dans la majeure partie de ces immeubles, les cloisons sont des cloisons démontables permettant la redisposition des locaux assez facilement. Ces cloisons sont montées entre plancher et faux plafond acoustique. Au-dessus du faux plafond il y a un vide.In most of these buildings, the partitions are demountable partitions allowing the rearrangement of the premises quite easily. These partitions are mounted between floor and false acoustic ceiling. Above the false ceiling there is a void.
On demande de plus en plus de performances acoustiques pour les cloisons, afin d'éviter la perception des conversations ou la gêne de bureau à bureau.There is an increasing demand for acoustic performance for partitions, in order to avoid the perception of conversations or discomfort from office to office.
Le bruit passe d'une part, au travers de la cloison, et d'autre part, par transmission indirecte : il passe dans le vide du faux plafond où il chemine, pour redescendre au travers du faux plafond dans le bureau voisin.The noise passes on the one hand, through the partition, and on the other hand, by indirect transmission: it passes in the void of the false ceiling where it travels, to descend through the false ceiling in the neighboring office.
Les plafonds acoustiques, pour être absorbants, doivent être poreux, et sont par conséquent faiblement atténuateurs.Acoustic ceilings, to be absorbent, must be porous, and are therefore weakly attenuating.
Pour éviter ce passage indirect du bruit, qui fait beaucoup chu-ter l'isolement sonore global entre deux bureaux, on met verticalement, en prolongement de la cloison séparant deux pièces, et au-dessus du faux plafond, une barrière phonique. Cette barrière phonique est une paroi plus ordinaire et simple que la cloison. Généralement, on utilise une plaque de plâtre ou d'aggloméré de bois, ou dans les cas plus performants, deux plaques de platre ou d'aggloméré, prenant en sandwich une couche de laine de verre ou de roche.To avoid this indirect passage of noise, which greatly reduces the overall sound isolation between two offices, we put vertically, in extension of the partition separating two rooms, and above the false ceiling, a sound barrier. This sound barrier is a more ordinary and simple wall than the partition. Generally, a plasterboard or chipboard is used, or in more efficient cases, two plaster or chipboard, sandwiching a layer of glass wool or rock wool.
Pour être efficace, la barrière doit être parfaitement ajustée, ainsi que toutes les découpes pour les éléments traversants, tels que, poutrelles , ossature du plafond avec toutes les entretoises en "T", passage de câbles ou de gaines, etc... En effet, sachant que 2 % de la surface en fentes ou trous provoquent une perte de l'atténuation phonique de 20 à 22 dB(A), on voit l'importance de la précision des découpes. Or, il n'est pas facile de relever les cotes avec précision, faire les découpes approchées, bien ajuster les panneaux rigides, ce qui entraîne soit des barrières phoniques beaucoup trop percées, aux performances médiocres, soit des travaux très longs et très onéreux. To be effective, the barrier must be perfectly adjusted, as well as all the cutouts for the through elements, such as, beams, ceiling framework with all the "T" spacers, passage of cables or ducts, etc ... Indeed, knowing that 2% of the surface in slots or holes causes a loss of sound attenuation from 20 to 22 dB (A), we see the importance of the precision of the cuts. However, it is not easy to take the dimensions with precision, make the approximate cuts, properly adjust the rigid panels, which leads either to too much broken through sound barriers, with poor performance, or very long and very expensive works.
Le dispositif suivant la présente invention supprime tous ces inconvénients. En effet, il permet d'cbtenir des barrières phoniques souples et compressibles, pouvant se satisfaire de découpes peu précises, faciles à mettre en oeuvre, tout en procurant une excellente étanchéité au bruit et, par conséquent, de très bonnes performances acoustiques.The device according to the present invention eliminates all these drawbacks. In fact, it makes it possible to obtain flexible and compressible sound barriers, which can be satisfied with imprecise cuts, which are easy to implement, while providing an excellent seal against noise and, consequently, very good acoustic performance.
Il est constitué par la combinaison d'un panneau de matériau poreux, absorbant et non rigide, telles que mousse synthétique ou laine de verre ou de roche de haute densité, d'une épaisseur suffisante pour jouer le rôle de silencieux, sur les deux faces duquel on a projeté ou collé une couche de matériau viscoélastique amortissant et atténuateur, de manière à créer une double cloison selon le principe "masse-ressort-masse", les faces des panneaux de fibres étant constituées d'un voile textile améliorant 1 'accrochage.It consists of the combination of a panel of porous, absorbent and non-rigid material, such as synthetic foam or high density glass or rock wool, of sufficient thickness to act as a silencer, on both sides. from which a layer of shock absorbing and attenuating viscoelastic material has been projected or glued, so as to create a double partition according to the "mass-spring-mass" principle, the faces of the fiber panels being made up of a textile web improving the adhesion .
On obtient ainsi un panneau multi-couches très léger, souple, se fixant sans accessoires par forçage élastique entre plafond et faux plafond, déccupable à la lame (cutter), permettant de faire des découpes approximatives, de préférence plus petites que l'objet traversant, sur lequel elles s'ajusteront correctement, grâce à l'élasticité du matériau.This gives a very light, flexible multi-layer panel, which can be fixed without accessories by elastic forcing between the ceiling and false ceiling, can be cut off with a blade (cutter), making it possible to make rough cuts, preferably smaller than the object passing through. , on which they will fit correctly, thanks to the elasticity of the material.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de l'invention
La figure 1 représente schématiquement le passage du bruit entre deux pièces adjacentes équipées de faux plafond.In the accompanying drawings, given by way of nonlimiting example of one of the forms of the invention
Figure 1 schematically shows the passage of noise between two adjacent rooms with false ceilings.
La figure 2 est une coupe schématique montrant la structure de la barrière phonique.Figure 2 is a schematic section showing the structure of the sound barrier.
La figure 3 illustre la mise en oeuvre de l'objet de l'invention.Figure 3 illustrates the implementation of the object of the invention.
La figure 1 montre deux pièces adjacentes 1, 2 séparées par une cloison acoustique 3 allant du sol G au faux plafond 5. Cela laisse entre le faux plafond et le plafond 6 un vide 7. Le bruit gênant, pour aller de la pièce 1 vers la pièce 2 par exemple, peut traverser la cloison 3 suivant la flèche 17 ou passer par le vide 7 en suivant le cheminerr.ent figuré par les flèches 18. Figure 1 shows two adjacent rooms 1, 2 separated by an acoustic partition 3 going from the floor G to the false ceiling 5. This leaves a void between the false ceiling and the ceiling 6 7. The annoying noise, to go from room 1 to the part 2 for example, can pass through the partition 3 along the arrow 17 or pass through the void 7 by following the path shown by the arrows 18.
Pour éviter cela, on met en place une barrière phonique 8 selon l'invention, venant se bloquer par force entre le faux plafond 5 et le plafond 6, et constituée (fig 2) d'un panneau 19 de laine de roche ou de verre de densité appropriée, dont les deux faces consistent en un voile textile 20 sur lequel est projetée ou collée de chaque côté du panneau, une mince paroi constituée d'un matériau viscoélastique 21 amortissant et atténuateur, de manière à former une double cloison isolante, souple et élastique.To avoid this, a sound barrier 8 is put in place according to the invention, which is blocked by force between the false ceiling 5 and the ceiling 6, and consisting (fig 2) of a panel 19 of rock wool or glass. of appropriate density, the two faces of which consist of a textile web 20 on which is projected or glued on each side of the panel, a thin wall made of a viscoelastic material 21 damping and attenuating, so as to form a double insulating, flexible partition and elastic.
Le panneau de fibre recouvert de voiles textiles peut être remplacé par un panneau en mousse synthétique.The fiber panel covered with textile sails can be replaced by a synthetic foam panel.
Le matériau viscoélastique 21 peut être de qualité anti-feu, ce qui avec un panneau 19 en laine de roche avec surfaces en voile de verre peut rendre l'ensemble de la barrière phonique incombustible, et même coupe-feu.The viscoelastic material 21 can be of fire-resistant quality, which with a rock wool panel 19 with glass fleece surfaces can make the entire sound barrier non-combustible, and even fire-resistant.
La figure 3 montre un exemple, courant de mise en oeuvre de l'objet de l'invention. Les éléments 9, 13 de l'ossature du faux plafond 5 passent au travers de la barrière phonique 8 grâce à un simple trait de couteau 10, 14 effectué à sa base. La barrière phonique est traversée par une canalisation 11, pour laquelle le poseur a effectué au cutter une découpe légèrement plus petire que la canalisation, sur laquelle la barrière 8 vient s'appliquer de façon étanche grâce à sa compressibilité.Figure 3 shows an example, current implementation of the object of the invention. The elements 9, 13 of the framework of the false ceiling 5 pass through the sound barrier 8 by means of a simple knife line 10, 14 made at its base. The sound barrier is crossed by a pipe 11, for which the installer has made a cutter slightly smaller than the pipe, on which the barrier 8 is applied tightly thanks to its compressibility.
Les tiges de suspension 15 du faux plafond 5 situées au droit de la cloison 3 sont introduites à l'intérieur de la barrière phonique 8 en pratiquant simplement dans cette dernière une fente verticale à mi-épaisseur.The suspension rods 15 of the false ceiling 5 located to the right of the partition 3 are introduced inside the sound barrier 8 by simply practicing in the latter a vertical slit at mid-thickness.
Grâce à ses performances acoustiques, et surtout à sa mise en oeuvre particulièrement aisée et peu onéreuse, la barrière phonique objet de l'invention peut être utilisée avantageusement en particulier lorsqu'une bonne isolation acoustique est recherchée entre des pièces équipées de faux plafonds, mais également dans tous les cas où le barrage phonique envisagé ne nécessite pas de résistance mécanique.Thanks to its acoustic performance, and especially to its particularly easy and inexpensive implementation, the sound barrier object of the invention can be used advantageously in particular when good sound insulation is sought between rooms with false ceilings, but also in all cases where the planned sound barrier does not require mechanical resistance.
Le positionnement des divers éléments constitutifs donnent à ce dispositif un maximum d'effets utiles qui n'avaient pas été obtenus à ce jour par des effets similaires.The positioning of the various constituent elements gives this device a maximum of useful effects which had not been obtained to date by similar effects.
Cependant, les formes et dispositions des différents éléments, ainsi que les matières utilisées pour leur fabrication, pourront varier dans la limite des équivalents, sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes and arrangements of the various elements, as well as the materials used for their manufacture, may vary within the limit of equivalents, without changing the general conception of the invention which has just been described.
