Titre de l'invention : Title of the invention:
REVETEMENT MURAL D'INTERIEUR POUR L'ISOLATION ACOUSTIQUE INTERIOR WALL COVERING FOR SOUND INSULATION
[0001] La présente invention concerne un revêtement d’intérieur pour l’isolation acoustique. [0001] The present invention relates to an interior covering for acoustic insulation.
[0002] Un tel revêtement est utilisé pour tapisser une paroi d’un local, pouvant par exemple être un plafond, un mur ou un plancher. Le terme « local » désigne tout lieu fermé dans lequel peuvent évoluer des individus, et peut donc par exemple désigner un appartement, une maison, une installation industrielle, un établissement public. Ce revêtement a pour but de réduire les nuisances sonores dans ces locaux afin d’améliorer le confort des occupants desdits locaux. [0002] Such a covering is used to line a wall of a room, which may for example be a ceiling, a wall or a floor. The term “premises” designates any closed place in which individuals can operate, and can therefore, for example, designate an apartment, a house, an industrial installation, a public establishment. This covering aims to reduce noise pollution in these premises in order to improve the comfort of the occupants of said premises.
[0003] Ce type de revêtement doit répondre aux moins à quatre exigences : [0003] This type of coating must meet at least four requirements:
-il doit pouvoir être monté facilement et rapidement sur la paroi visée, -it must be able to be mounted easily and quickly on the target wall,
-il doit être réellement efficace pour atténuer le bruit, -it must be really effective in reducing noise,
-il doit être plus mince que les solutions actuelles, -it must be thinner than current solutions,
-il doit avoir une tenue robuste sur cette paroi, sans risque d’une dérive de positionnement ou de dégradation au cours du temps. -it must have a robust hold on this wall, without risk of positioning drift or degradation over time.
[0004] Un revêtement selon l’invention répond aux exigences susmentionnées. [0004] A coating according to the invention meets the aforementioned requirements.
[0005] L’invention a pour objet un revêtement insonorisant, destiné à être apposé contre une surface intérieure d’au moins une paroi d’un local. [0005] The subject of the invention is a sound-absorbing covering, intended to be placed against an interior surface of at least one wall of a room.
[0006] Selon l’invention, le revêtement comprend au moins deux panneaux d’insonorisation en contact latéral l’un avec l’autre, et chaque panneau comprend : [0006] According to the invention, the covering comprises at least two soundproofing panels in lateral contact with one another, and each panel comprises:
-une couche externe qui est destinée à être visible depuis l’intérieur du local et qui est constituée d’une couche de forte densité, comprise entre 450kg/m3 et 950 kg/m3, -an external layer which is intended to be visible from inside the room and which is made up of a high density layer, between 450 kg/m 3 and 950 kg/m 3 ,
-une couche interne qui est destinée à être en contact avec la surface intérieure de la paroi et qui est constituée d’une couche de forte densité, comprise entre 450kg/m3 et 950 kg/m3, -an internal layer which is intended to be in contact with the interior surface of the wall and which is made up of a high density layer, between 450 kg/m 3 and 950 kg/m 3 ,
-une couche intermédiaire qui est insérée entre la couche externe et la couche interne et qui est constituée d’un matériau absorbant phonique. Le revêtement insonorisant selon l’invention est constitué de plusieurs panneaux individuels comprenant chacun deux couches de forte densité encadrant une couche d’un matériau insonorisant. Ces panneaux sont destinés à être apposés contre la surface intérieure de la paroi du local. Le terme « apposé » sous-entend une mise en contact du panneau contre la surface intérieure de la paroi, avec un plan d’interface étendu, et également une fixation dudit panneau à ladite surface intérieure. En effet, chaque panneau peut être fixé à ladite surface intérieure par tout moyen, notamment par collage. Comme la couche interne de forte densité d’un panneau est amené à être au contact de la surface intérieure de la paroi du local, il faut qu’elle présente une certaine solidité pour assurer une bonne tenue mécanique du panneau contre ladite surface intérieure. Cette couche externe matérialise la partie du panneau qui sera visible depuis l’intérieur du local, et est donc susceptible d’être recouverte par une peinture, un papier peint ou tout autre revêtement de finition. Le local peut par exemple représenter un appartement, une maison, une installation industrielle, un établissement public, etc. La paroi peut par exemple être un mur vertical, un plafond, une face inclinée, un plancher, etc. Pour lever toute ambiguïté, le revêtement insonorisant est destiné à se retrouver à l’intérieur du local. Le revêtement insonorisant crée une surépaisseur qui va permettre à des personnes présentes dans le local d’être isolée des bruits extérieurs. Le matériau insonorisant se trouvant entre les deux couches de forte densité peut par exemple être constitué d’une laine minérale, de verre ou de roche, de liège, de laine biosourcée, etc. Lorsqu’il s’agit de laine minérale, celle- ci peut être neuve ou recyclée. Les panneaux d’insonorisation peuvent être accolés les uns aux autres par tout moyen, pour former un revêtement insonorisant monocouche et continu. -an intermediate layer which is inserted between the outer layer and the inner layer and which is made of a sound absorbing material. The sound-absorbing covering according to the invention consists of several individual panels each comprising two high-density layers framing a layer of a sound-absorbing material. These panels are intended to be affixed against the interior surface of the wall of the room. The term “affixed” implies bringing the panel into contact with the interior surface of the wall, with an extended interface plane, and also fixing said panel to said interior surface. Indeed, each panel can be fixed to said interior surface by any means, in particular by gluing. As the high density internal layer of a panel is brought into contact with the interior surface of the wall of the room, it must have a certain solidity to ensure good mechanical strength of the panel against said interior surface. This external layer represents the part of the panel which will be visible from inside the premises, and is therefore likely to be covered by paint, wallpaper or any other finishing covering. The premises can for example represent an apartment, a house, an industrial installation, a public establishment, etc. The wall can for example be a vertical wall, a ceiling, an inclined face, a floor, etc. For the avoidance of doubt, the sound-absorbing covering is intended to be found inside the premises. The sound-absorbing covering creates an extra thickness which will allow people present in the room to be isolated from external noise. The sound-absorbing material located between the two high-density layers can for example consist of mineral wool, glass or rock wool, cork, bio-sourced wool, etc. When it comes to mineral wool, it can be new or recycled. The soundproofing panels can be joined to each other by any means, to form a single-layer and continuous sound-absorbing covering.
[0007] Selon une caractéristique possible de l’invention, la couche intermédiaire comprend une laine minérale de verre ou de roche. Cette laine minérale peut être neuve ou recyclée. La couche intermédiaire est préférentiellement fibreuse. Autrement dit, elle n’est pas tassée à son maximum pour conserver un aspect aéré et ainsi se différencier d’une couche pleine et dure qui aurait tendance à transmettre les ondes sonores plutôt qu’à les amortir. [0007] According to a possible characteristic of the invention, the intermediate layer comprises a glass or rock mineral wool. This mineral wool can be new or recycled. The intermediate layer is preferably fibrous. In other words, it is not packed as tightly as possible to maintain an airy appearance and thus differentiate itself from a solid, hard layer which would tend to transmit sound waves rather than dampen them.
[0008] Selon une caractéristique possible de l’invention, la densité de la couche intermédiaire est inférieure à 250kg/m3. Cette faible densité démontre le côté aéré de la couche intermédiaire, de manière à jouer son rôle d’amortisseur sonore avec un maximum d’efficacité. [0009] Selon une caractéristique possible de l’invention, l’épaisseur de chaque panneau est comprise entre 15mm et 50mm. Ces panneaux sont peu épais et peuvent donc être apposés sur n’importe quel type de surface interne, y compris celles qui sont difficilement accessibles, c’est-à-dire celles ne bénéficiant pas d’un espace de dégagement important. [0008] According to a possible characteristic of the invention, the density of the intermediate layer is less than 250 kg/m3. This low density demonstrates the airy side of the intermediate layer, so as to play its role as a sound absorber with maximum efficiency. [0009] According to a possible characteristic of the invention, the thickness of each panel is between 15mm and 50mm. These panels are thin and can therefore be affixed to any type of internal surface, including those that are difficult to access, i.e. those that do not have significant clearance space.
[00010] Selon une caractéristique possible de l’invention, l’épaisseur de chaque panneau est comprise entre 25mm et 30mm. Il s’agit d’une épaisseur optimale, qui n’est nullement limitative dans le cadre de la présente invention. [00010] According to a possible characteristic of the invention, the thickness of each panel is between 25mm and 30mm. This is an optimal thickness, which is in no way limiting in the context of the present invention.
[00011] Selon une caractéristique possible de l’invention, chaque panneau comprend au moins un clip et un clip complémentaire, de sorte que deux panneaux successifs soient fixés l’un à l’autre par une interaction entre un clip de l’un des panneaux et un clip complémentaire de l’autre panneau. Ce type d’interaction entre panneaux va permettre d’assurer une grande cohésion du revêtement insonorisant. En effet, ces interactions de type « clip/clip complémentaire » vont assurer des liaisons homogènes et solides entre les panneaux, empêchant que la position de ces panneaux ne subisse une dérive dans le temps, et donc en assurant une bonne stabilité positionnelle du revêtement insonorisant. Grâce à ce type d’interactions, le revêtement insonorisant donnera une impression de continuité géométrique. [00011] According to a possible characteristic of the invention, each panel comprises at least one clip and a complementary clip, so that two successive panels are fixed to one another by an interaction between a clip of one of the panels and a complementary clip from the other panel. This type of interaction between panels will ensure great cohesion of the sound-absorbing covering. Indeed, these “clip/complementary clip” type interactions will ensure homogeneous and solid connections between the panels, preventing the position of these panels from drifting over time, and therefore ensuring good positional stability of the sound-absorbing covering. . Thanks to this type of interaction, the sound-absorbing covering will give an impression of geometric continuity.
[00012] Selon une caractéristique possible de l’invention, le clip et le clip complémentaire, sont réalisés dans la couche externe de chaque panneau. Cette couche externe étant la seule des trois couches des panneaux à ne pas avoir de fonction particulière, il est logique que les moyens d’accrochage desdits panneaux entre eux, soient reportés sur celle-ci. [00012] According to a possible characteristic of the invention, the clip and the complementary clip are made in the outer layer of each panel. This outer layer being the only one of the three layers of the panels not to have a particular function, it is logical that the means of attaching said panels to each other are transferred to it.
[00013] Selon une caractéristique possible de l’invention, le clip est constitué par une avancée de la couche externe qui saille du panneau, et le clip complémentaire est constitué par une zone d’extrémité de la couche externe ne saillant pas du panneau, le clip et le clip complémentaire possédant des formes complémentaires s’emboitant l’une dans l’autre. Ces moyens de clippage sont particulièrement adaptés à la fixation des panneaux d’insonorisation d’un revêtement insonorisant selon l’invention, mais ne sont nullement limitatifs dans le cadre de la présente invention. D’autres types de clips et de clips complémentaires peuvent être envisagés. [00014] Les panneaux peuvent aussi être maintenu mécaniquement ensemble par collage, clouage ou visage d’une forme mâle et femelle sur la partie latérale. [00013] According to a possible characteristic of the invention, the clip is constituted by an advance of the external layer which projects from the panel, and the complementary clip is constituted by an end zone of the external layer not projecting from the panel, the clip and the complementary clip having complementary shapes fitting into each other. These clipping means are particularly suitable for fixing the soundproofing panels of a soundproofing covering according to the invention, but are in no way limiting in the context of the present invention. Other types of clips and complementary clips can be considered. [00014] The panels can also be held together mechanically by gluing, nailing or facing a male and female shape on the side part.
[00015] L’invention a pour autre objet un local comprenant au moins une paroi dotée d’une surface intérieure. [00015] Another object of the invention is a room comprising at least one wall with an interior surface.
[00016] Selon l’invention, ladite surface intérieure est tapissée avec plusieurs panneaux d’insonorisation d’un revêtement insonorisant selon l’invention, les couches internes desdits panneaux étant en contact avec la surface intérieure de la paroi, lesdits panneaux étant arrimés à ladite surface intérieure par collage au moyen d’une couche d’adhésif insérée entre ladite surface intérieure et les couches internes desdits panneaux, deux panneaux successifs étant fixés l’un à l’autre par clippage. La couche adhésive peut être directement intégrée au panneau en étant constitutif de la couche interne et protégée avant son utilisation par une couche fine pelable. Le revêtement insonorisant d’un local selon l’invention est robuste et homogène, en raison d’un double niveau de fixation : - une fixation des panneaux d’insonorisation à la surface interne de la paroi par collage, [00016] According to the invention, said interior surface is lined with several soundproofing panels with a sound-absorbing covering according to the invention, the internal layers of said panels being in contact with the interior surface of the wall, said panels being secured to said interior surface by gluing by means of a layer of adhesive inserted between said interior surface and the internal layers of said panels, two successive panels being fixed to one another by clipping. The adhesive layer can be directly integrated into the panel as a constituent of the internal layer and protected before use by a thin peelable layer. The soundproofing covering of a room according to the invention is robust and homogeneous, due to a double level of fixing: - fixing of the soundproofing panels to the internal surface of the wall by gluing,
-une fixation des panneaux d’insonorisation entre eux par clippage. -fixing the soundproofing panels together by clipping.
[00017] De cette manière, un tel revêtement insonorisant ne risque pas de se modifier au cours du temps par un déplacement progressif des panneaux. [00017] In this way, such a sound-absorbing covering does not risk changing over time by progressive movement of the panels.
[00018] L’invention a pour autre objet un procédé de dépôt d’un revêtement insonorisant selon l’invention, sur une surface intérieure d’une paroi d’un local, ledit revêtement comprenant plusieurs panneaux d’insonorisation. [00018] Another subject of the invention is a method of depositing a sound-absorbing coating according to the invention, on an interior surface of a wall of a room, said coating comprising several sound-proofing panels.
[00019] Selon l’invention, le procédé comprend les étapes suivantes : [00019] According to the invention, the method comprises the following steps:
-une étape d’enduction d’une surface externe de la couche interne d’un premier panneau d’insonorisation avec un adhésif, ledit premier panneau comprenant un clip, -a step of coating an external surface of the internal layer of a first soundproofing panel with an adhesive, said first panel comprising a clip,
-une étape de collage dudit premier panneau sur la surface intérieure de la paroi du local, -a step of gluing said first panel to the interior surface of the wall of the room,
-une étape d’enduction d’une surface externe de la couche interne d’un deuxième panneau d’insonorisation avec l’adhésif, ledit deuxième panneau comprenant un clip complémentaire, -a step of coating an external surface of the internal layer of a second soundproofing panel with the adhesive, said second panel comprising a complementary clip,
-une étape de clippage du deuxième panneau au premier panneau, au moyen d’une interaction entre le clip et le clip complémentaire, -a step of clipping the second panel to the first panel, by means of an interaction between the clip and the complementary clip,
-une étape de collage dudit deuxième panneau sur la surface intérieure de la paroi du local, -a step of gluing said second panel to the interior surface of the wall of the room,
-une étape de répétition des étapes précédentes en fonction du nombre de panneaux d’insonorisation à fixer à la surface intérieure de la paroi du local. -a step of repeating the previous steps depending on the number of soundproofing panels to be fixed to the interior surface of the wall of the room.
[00020] Un revêtement insonorisant selon l’invention présente l’avantage de pouvoir être mis en œuvre progressivement au moyen de plusieurs panneaux d’insonorisation, permettant un montage précis et bien maitrisé de ce revêtement insonorisant. Il a de plus l’avantage d’être homogène et de présenter une bonne stabilité positionnelle, grâce à une première fixation des panneaux d’insonorisation sur la surface interne d’une paroi d’un local, et grâce à une deuxième fixation desdits panneaux entre eux. Il présente enfin l’avantage de posséder une épaisseur particulièrement réduite par rapport à celle des systèmes de doublage acoustique existants, permettant de limiter la perte du volume disponible dans la pièce dans laquelle il est destiné à être posé et permettant une manipulation plus aisée des panneaux qui le composent. [00020] A soundproofing covering according to the invention has the advantage of being able to be implemented progressively by means of several soundproofing panels, allowing precise and well-controlled assembly of this soundproofing covering. It also has the advantage of being homogeneous and having good positional stability, thanks to a first fixing of the soundproofing panels on the internal surface of a wall of a room, and thanks to a second fixing of said panels between them. Finally, it has the advantage of having a particularly reduced thickness compared to that of existing acoustic doubling systems, making it possible to limit the loss of available volume in the room in which it is intended to be installed and allowing easier handling of the panels. which compose it.
[00021] On donne ci-après une description détaillée d’un mode de réalisation préféré d’un revêtement selon l’invention, en se référant aux figures suivantes : [00021] A detailed description of a preferred embodiment of a coating according to the invention is given below, with reference to the following figures:
[00022] [Fig. 1] La figure 1 est une en coupe schématique d’un revêtement insonorisant selon l’invention, [00022] [Fig. 1] Figure 1 is a schematic section of a sound-absorbing covering according to the invention,

[00025] [Fig. 4] La figure 4 est une vue en perspective d’une zone d’un panneau d’insonorisation d’un revêtement insonorisant selon l’invention et portant un clip,[00025] [Fig. 4] Figure 4 is a perspective view of an area of a soundproofing panel of a soundproofing covering according to the invention and carrying a clip,
[00026] [Fig. 5] La figure 5 est une vue en perspective d’une zone d’un panneau d’insonorisation d’un revêtement insonorisant selon l’invention et portant un clip complémentaire, [00026] [Fig. 5] Figure 5 is a perspective view of an area of a soundproofing panel of a soundproofing covering according to the invention and carrying a complementary clip,
[00027] [Fig. 6] La figure 6 est une vue en perspective de deux panneaux successifs d’un revêtement insonorisant selon l’invention, l’un des deux panneaux portant un clip et l’autre panneau portant un clip complémentaire, les deux panneaux étant orientés dans l’espace de façon à faire entrevoir leur interaction, [00028] [Fig. 7] La figure 7 est une vue en perspective d’un revêtement insonorisant selon l’invention, pour lequel chaque panneau s’étend sur toute la hauteur de parois à couvrir, [00027] [Fig. 6] Figure 6 is a perspective view of two successive panels of a sound-absorbing covering according to the invention, one of the two panels carrying a clip and the other panel carrying a complementary clip, the two panels being oriented in the space so as to show their interaction, [00028] [Fig. 7] Figure 7 is a perspective view of a sound-absorbing covering according to the invention, for which each panel extends over the entire height of the walls to be covered,
[00029] En se référant à la figure 1 , un revêtement insonorisant 1 selon l’invention comprend plusieurs panneaux 2 d’insonorisation distincts, et destinés à venir se poser contre une surface intérieure 3 d’une paroi 4 d’un local 5 pouvant par exemple être un appartement, une maison, une installation industrielle ou un établissement public. Plus généralement, un tel local 5 représente tout lieu fermé dans lequel est susceptible d’évoluer des personnes. La paroi 4 sur laquelle peut être apposé un revêtement insonorisant 1 selon l’invention, peut indifféremment être représenté par un mur vertical, un plafond horizontal ou incliné, un plancher, etc. A titre d’exemple, supposons que les panneaux initiaux A sont tous identiques et possèdent la même longueur. Certains de ces panneaux A pourront être posés tels quels sur la surface intérieure 3 de la paroi 4 du local, et certains autres panneaux B devront être découpés en deux parties pour compléter une bande verticale de revêtement insonorisant afin qu’elle s’étende sur toute la hauteur de ladite surface intérieure 3. L’autre partie du panneau B découpé pourra alors démarrer une autre bande verticale de revêtement insonorisant 1 . [00029] Referring to Figure 1, a sound-absorbing covering 1 according to the invention comprises several distinct sound-proofing panels 2, and intended to be placed against an interior surface 3 of a wall 4 of a room 5 which can for example being an apartment, a house, an industrial installation or a public establishment. More generally, such a room 5 represents any closed place in which people are likely to move. The wall 4 on which a sound-absorbing covering 1 according to the invention can be affixed, can indifferently be represented by a vertical wall, a horizontal or inclined ceiling, a floor, etc. For example, let's assume that the initial panels A are all identical and have the same length. Some of these panels A can be placed as is on the interior surface 3 of the wall 4 of the room, and certain other panels B will have to be cut into two parts to complete a vertical strip of sound-absorbing covering so that it extends over the entire the height of said interior surface 3. The other part of the cut panel B can then start another vertical strip of sound-absorbing covering 1.
[00030] En se référant aux figures 2 et 3, tous les panneaux 2 d’un même revêtement insonorisant 1 sont constitués d’un empilement de trois couches, à savoir : [00030] Referring to Figures 2 and 3, all the panels 2 of the same sound-absorbing covering 1 are made up of a stack of three layers, namely:
- une couche externe 6 qui est visible depuis l’intérieur du local 5 et qui est composée d’une couche de forte densité, comprise entre 450kg/m3 et 950kg/m3.- an external layer 6 which is visible from inside the room 5 and which is composed of a high density layer, between 450kg/m 3 and 950kg/m 3 .
Il peut s’agir d’un bois massif, d’un aggloméré, d’un compacté, d’un composite ou même de plaque de plâtre. Cette couche externe 6, puisqu’elle est visible depuis l’intérieur du local 5, est susceptible d’être recouverte par une peinture, un enduit, un papier-peint ou tout autre revêtement de décoration pour améliorer l’esthétique du revêtement insonorisant 1 , -une couche interne 8 qui est destinée à être en contact avec la surface intérieure 3 de la paroi 4 du local 5, et qui est composée d’une couche de forte densité, comprise entre 450 et 950 kg/m3. Le choix d’un matériau à forte densité pour cette couche interne permet à cette couche d’être de faible épaisseur et d’assurer aux panneaux d’insonorisation 2 une bonne tenue mécanique contre la surface intérieure 3 de la paroi 4 du local 5. Préférentiellement l’épaisseur de la couche interne 8 est inférieure ou égale à celle de la couche externe 6. -une couche intermédiaire 7 qui est insérée entre la couche externe 6 et la couche interne 8 et qui est constituée d’un matériau absorbant phonique. Un tel matériau peut avantageusement être matérialisé par de la laine minérale, de verre ou de roche. Cette couche intermédiaire 7 constitue le cœur du panneau 2, puisque c’est essentiellement par son intermédiaire que ledit panneau 2 va assurer la fonction ressort du complexe acoustique. La fibre minérale n’est pas tassée à son maximum afin de ne pas constituer une couche pleine, qui serait susceptible de transmettre les ondes sonores et non pas de les amortir. La laine minérale apparait donc sous forme fibreuse conférant à la couche intermédiaire un aspect plutôt aéré, dont la densité est typiquement inférieure ou égale à 250kg/m3. It can be solid wood, chipboard, compacted wood, composite or even plasterboard. This external layer 6, since it is visible from inside the room 5, is capable of being covered by a paint, a coating, a wallpaper or any other decorative covering to improve the aesthetics of the sound-absorbing covering 1 , -an internal layer 8 which is intended to be in contact with the interior surface 3 of the wall 4 of the room 5, and which is composed of a high density layer, between 450 and 950 kg/m3. The choice of a high density material for this internal layer allows this layer to be of low thickness and to ensure that the soundproofing panels 2 have good mechanical strength against the interior surface 3 of the wall 4 of the room 5. Preferably the thickness of the internal layer 8 is less than or equal to that of the external layer 6. -an intermediate layer 7 which is inserted between the external layer 6 and the internal layer 8 and which is made of a sound absorbing material. Such a material can advantageously be made from mineral, glass or rock wool. This intermediate layer 7 constitutes the heart of the panel 2, since it is essentially through it that said panel 2 will ensure the spring function of the acoustic complex. The mineral fiber is not packed as tightly as possible so as not to form a solid layer, which would be likely to transmit sound waves and not damp them. Mineral wool therefore appears in fibrous form giving the intermediate layer a rather airy appearance, the density of which is typically less than or equal to 250kg/m 3 .
[00031] L’épaisseur d’un panneau 2 d’insonorisation d’un revêtement insonorisant 1 selon l’invention, est comprise entre 15mm et 50mm, et préférentiellement est comprise entre 25 et 30mm. [00031] The thickness of a soundproofing panel 2 of a soundproofing covering 1 according to the invention is between 15mm and 50mm, and preferably is between 25 and 30mm.
[00032] En se référant à la figure 3, un panneau 2 d’un revêtement insonorisant selon l’invention, reprend le principe d’isolation acoustique « masse-ressort- masse ». Une onde sonore 9 arrive contre la couche externe 6 de forte densité d’un panneau 2. Une fraction majoritaire 10 de cette onde sonore traverse cette couche externe 6, tandis qu’une fraction minoritaire 11 est réfléchie hors dudit panneau 2. Arrivée dans la couche intermédiaire 7, la fraction majoritaire 10 de l’onde sonore 9 qui a traversé la couche externe 6, se diffracte dans tous les sens en se subdivisant en plusieurs composantes 12, 13, 14, 15 de faible intensité chacune. Cette diffraction amortit grandement l’onde sonore initiale. L’une 15 de ces composantes parvient à traverser la couche interne 8 avec une très faible intensité. Entre l’onde sonore 9 incidente possédant une certaine intensité, et la composante 25 de faible intensité de ladite onde sonore 9 parvenant à sortir de la couche interne 8 du panneau 2. Un revêtement insonorisant selon l’invention parvient ainsi à diminuer les bruits aériens de 2 à 10 dB lorsqu’il est installé en doublage sur une parois et de 20 à 35dB en cloisonnement. Les valeurs varient selon l’épaisseur total du panneau et la nature de ses constituants. [00032] Referring to Figure 3, a panel 2 of a sound-absorbing covering according to the invention uses the “mass-spring-mass” sound insulation principle. A sound wave 9 arrives against the high density outer layer 6 of a panel 2. A majority fraction 10 of this sound wave passes through this outer layer 6, while a minority fraction 11 is reflected outside said panel 2. Arrival in the intermediate layer 7, the majority fraction 10 of the sound wave 9 which has passed through the external layer 6, diffracts in all directions, subdividing into several components 12, 13, 14, 15 each of low intensity. This diffraction greatly dampens the initial sound wave. One 15 of these components manages to cross the internal layer 8 with a very low intensity. Between the incident sound wave 9 having a certain intensity, and the low intensity component 25 of said sound wave 9 managing to emerge from the internal layer 8 of the panel 2. A sound-absorbing coating according to the invention thus succeeds in reducing airborne noise from 2 to 10 dB when installed in lining on a wall and from 20 to 35dB in partitioning. The values vary depending on the total thickness of the panel and the nature of its constituents.
[00033] Chacun des panneaux 2 d’un revêtement insonorisant 1 selon l’invention présente deux moyens de fixation : -un premier moyen de fixation à la surface intérieure 3 de la paroi 4 du local 5. Préférentiellement, ce premier moyen de fixation est réalisé par collage. Une couche d’un adhésif est déposée sur une surface externe de la couche interne 8 du panneau 2, puis le panneau 2 est collé à la surface intérieure 3 de la paroi 4 du local 5 par l’intermédiaire de cette couche d’adhésif. De cette manière, la couche interne 8 du panneau 2 se retrouve au contact de la surface intérieure 3 de la paroi 4 du local 5, et la couche externe 6 dudit panneau 2 constitue la couche la plus éloignée de ladite surface intérieure 3. L’adhésif peut par exemple être un mortier colle ou de la colle mastic. [00033] Each of the panels 2 of a sound-absorbing covering 1 according to the invention has two fixing means: -a first means of fixing to the interior surface 3 of the wall 4 of the room 5. Preferably, this first means of fixing is produced by gluing. A layer of adhesive is deposited on an external surface of the internal layer 8 of the panel 2, then the panel 2 is glued to the interior surface 3 of the wall 4 of the room 5 via this layer of adhesive. In this way, the internal layer 8 of the panel 2 is found in contact with the interior surface 3 of the wall 4 of the room 5, and the exterior layer 6 of said panel 2 constitutes the layer furthest from said interior surface 3. adhesive can for example be an adhesive mortar or putty glue.
-un deuxième moyen de fixation à un panneau 2 d’insonorisation adjacent. En se référant aux figures 4, 5 et 6, la fixation d’un premier panneau 2 à un deuxième panneau 2 adjacent s’effectue par clippage. Le premier panneau 2 comprend un clip 16 et le deuxième panneau 2 comprend un clip complémentaire 17 destiné à coopérer avec le clip 16 du premier panneau 2, pour assurer une fixation entre les deux panneaux 2. -a second means of attachment to an adjacent soundproofing panel 2. Referring to Figures 4, 5 and 6, the fixing of a first panel 2 to an adjacent second panel 2 is carried out by clipping. The first panel 2 comprises a clip 16 and the second panel 2 comprises a complementary clip 17 intended to cooperate with the clip 16 of the first panel 2, to ensure fixation between the two panels 2.
[00034] En se référant à la figure 4, le clip 16 d’un premier panneau 2 est constitué par une extension 18 de la couche externe 6 qui saille du panneau 2. Cette extension 18 est plane et est de plus faible épaisseur que celle de ladite couche externe 6. Elle prolonge une zone la plus extérieure de ladite couche externe 6. Cette extension 18 s’étend sur toute la largeur de la couche externe 6 et comprend une rainure 19 arrondie s’étendant sur toute la largeur de ladite extension 18. [00034] Referring to Figure 4, the clip 16 of a first panel 2 is constituted by an extension 18 of the outer layer 6 which projects from the panel 2. This extension 18 is flat and is of lower thickness than that of said outer layer 6. It extends an outermost zone of said outer layer 6. This extension 18 extends over the entire width of the outer layer 6 and comprises a rounded groove 19 extending over the entire width of said extension 18.
[00035] En se référant à la figure 5, le clip complémentaire 17 d’un deuxième panneau 2 adjacent est constitué par une zone d’extrémité 20 de la couche externe 6, qui ne saille pas du panneau 2. Cette zone d’extrémité 20 est plane et est de plus faible épaisseur que celle de ladite couche externe 6. Elle prolonge une zone la plus intérieure de ladite couche externe 6. Cette zone d’extrémité 20 s’étend sur toute la largeur de la couche externe 6 et comprend une nervure 21 arrondie s’étendant sur toute la largeur de ladite zone d’extrémité 20. Referring to Figure 5, the complementary clip 17 of a second adjacent panel 2 is constituted by an end zone 20 of the outer layer 6, which does not protrude from the panel 2. This end zone 20 is flat and is of lower thickness than that of said outer layer 6. It extends an innermost zone of said outer layer 6. This end zone 20 extends over the entire width of the outer layer 6 and comprises a rounded rib 21 extending over the entire width of said end zone 20.
[00036] En se référant à la figure 6, le clippage entre le premier panneau et le deuxième panneau 2 est réalisé au moyen de l’insertion de la nervure arrondie 21 du clip complémentaire 17 de l’un des deux panneaux 2, dans la rainure arrondie 19 du clip 16 de l’autre panneau 2, les couches intermédiaires 8 et les couches internes 7 des deux panneaux 2 venant en contact les unes des autres lors de cette insertion. Les deux panneaux adjacents 2 donneront ainsi l’impression d’une parfaite continuité entre eux. [00036] Referring to Figure 6, the clipping between the first panel and the second panel 2 is carried out by means of the insertion of the rounded rib 21 of the complementary clip 17 of one of the two panels 2, in the rounded groove 19 of the clip 16 of the other panel 2, the intermediate layers 8 and the internal layers 7 of the two panels 2 coming into contact with each other during this insertion. The two adjacent panels 2 will thus give the impression of perfect continuity between them.
[00037] Lors de la mise en œuvre d’un revêtement insonorisant selon l’invention, certains panneaux 2 d’insonorisation auront pu être préalablement coupés, pour permettre d’adapter la surface du revêtement insonorisant 1 aux dimensions de la surface intérieure 3 de la paroi 4 du local 5 à couvrir. [00037] When implementing a sound-absorbing covering according to the invention, certain sound-proofing panels 2 could have been cut beforehand, to enable the surface of the sound-absorbing covering 1 to be adapted to the dimensions of the interior surface 3 of the wall 4 of room 5 to be covered.
[00038] Dans le cadre de la présente invention, il y a lieu de distinguer deux types différents de panneaux 2 : [00038] In the context of the present invention, it is necessary to distinguish two different types of panels 2:
-des panneaux allongés 2 couvrant à eux seuls toute la hauteur (ou la longueur) d’un mur sur lequel ils sont destinés à être apposés, comme l’illustre la figure 7. Ces panneaux 2 sont de forme rectangulaire et les deux grands côtés parallèles de ces panneaux 2 ont approximativement la même hauteur que celle dudit mur. Pour cette configuration particulière, ces panneaux 2 ne possèdent qu’un seul clip 16 s’étendant le long de l’un des deux grands côtés et un seul clip complémentaire 17 s’étendant le long de l’autre grand côté, -elongated panels 2 covering by themselves the entire height (or length) of a wall on which they are intended to be affixed, as illustrated in Figure 7. These panels 2 are rectangular in shape and the two long sides parallel of these panels 2 have approximately the same height as that of said wall. For this particular configuration, these panels 2 have only one clip 16 extending along one of the two long sides and a single complementary clip 17 extending along the other long side,
-des panneaux 2 de plus petite dimension comme illustré à la figure 1 , et qui sont amenés chacun à interagir par clippage sur quatre cotés avec d’autres panneaux 2 de plus petite dimension et situés autour. Ces panneaux 2 possèdent deux premiers côtés parallèles, dont l’un comprend un clip 16 et l’autre comprend un clip complémentaire 17, et deux deuxièmes côtés parallèles, dont l’un comprend un clip 16 et l’autre comprend un clip complémentaire 17. -panels 2 of smaller size as illustrated in Figure 1, and which are each made to interact by clipping on four sides with other panels 2 of smaller size and located around. These panels 2 have two first parallel sides, one of which includes a clip 16 and the other includes a complementary clip 17, and two second parallel sides, one of which includes a clip 16 and the other includes a complementary clip 17 .
[00039] Un procédé de dépôt d’un revêtement insonorisant selon l’invention, sur une surface intérieure 3 d’une paroi 4 d’un local 5, comprend les étapes suivantes : -une étape d’enduction d’une surface externe de la couche interne 8 d’un premier panneau 2 d’insonorisation avec un adhésif, ledit premier panneau 2 comprenant au moins un clip 16 et au moins un clip complémentaire 17, [00039] A method of depositing a sound-absorbing coating according to the invention, on an interior surface 3 of a wall 4 of a room 5, comprises the following steps: -a step of coating an external surface of the internal layer 8 of a first soundproofing panel 2 with an adhesive, said first panel 2 comprising at least one clip 16 and at least one complementary clip 17,
-une étape de collage dudit premier panneau 2 sur la surface intérieure 3 de la paroi 4 du local 5, -a step of gluing said first panel 2 on the interior surface 3 of the wall 4 of the room 5,
-une étape d’enduction d’une surface externe de la couche interne 8 d’un deuxième panneau 2 d’insonorisation avec l’adhésif, ledit deuxième panneau 2 comprenant au moins un clip 16 et un clip complémentaire 17, -a step of coating an external surface of the internal layer 8 of a second soundproofing panel 2 with the adhesive, said second panel 2 comprising at least one clip 16 and a complementary clip 17,
-une étape de clippage du deuxième panneau 2 au premier panneau 2 en faisant coopérer le clip 16 et le clip complémentaire 17 de chacun desdits panneaux 2, -une étape de collage dudit deuxième panneau 2 sur la surface intérieure 3 de la paroi 4 du local 5. -a step of clipping the second panel 2 to the first panel 2 by making the clip 16 and the complementary clip 17 of each of said panels 2 cooperate, -a step of bonding said second panel 2 to the interior surface 3 of the wall 4 of the room 5.
[00040] Les étapes précédentes se répéteront autant de fois qu’il y a de panneaux 2 d’insonorisation à fixer. [00041] Il est à noter que le clip 16 et le clip complémentaire 17 détaillés dans la description détaillée ci-avant, sont purement illustratifs et ne sont en aucune façon limitatifs dans le cadre de la présente invention. Le clip 16 et le clip complémentaires 17 sont configurés pour assurer entre eux une interaction de type mâle/femelle. Le clip 16 et le clip complémentaire 17 peuvent, soit s’étendre sur toute la longueur ou sur toute largeur du panneau 2 pour assurer une interaction étendue dans l’espace, soit être plus ponctuels de façon à assurer une interaction limitée dans l’espace. [00040] The previous steps will be repeated as many times as there are soundproofing panels 2 to be fixed. [00041] It should be noted that the clip 16 and the complementary clip 17 detailed in the detailed description above, are purely illustrative and are in no way limiting in the context of the present invention. The clip 16 and the complementary clip 17 are configured to ensure male/female type interaction between them.
