Description

PANNEAU DE CORRECTION ACOUSTIQUE ET PLAFOND EQUIPE D'UN ACOUSTIC CORRECTION PANEL AND CEILING EQUIPPED WITH
TEL PANNEAUTEL PANEL
L'invention a trait à un panneau de correction acoustique.The invention relates to an acoustic correction panel.
De tels panneaux permettent de réduire la résonance acoustique dans une pièce. Ils sont généralement fixés au plafond des pièces dont on veut réduire la résonance. Ils peuvent être également utilisés pour revêtir l'ensemble des murs de la pièce. On connaît par FR-A-2 748 505 un panneau d'absorption phonique et thermique comprenant une feuille de bois perforée collée sur une couche textile, elle-même collée sur une couche en laine minérale, c'est-à-dire en laine de verre ou laine de roche. En variante, la feuille de bois est d'une épaisseur suffisante pour être collée directement sur la couche de laine minérale sans nécessiter la présence d'une couche textile. La rigidité d'un tel panneau est obtenue d'une part, par l'épaisseur de la couche de laine minérale et, d'autre part, par l'épaisseur du revêtement en bois ou de la couche textile collée sur ce dernier. On connaît également par FR-A-2 859 492 un panneau en laine de roche revêtu sur la face visible d'une plaque de bois stratifié et perforé et, sur la face arrière, d'une autre plaque de bois stratifié permettant la rigidification du panneau.Such panels reduce the acoustic resonance in a room. They are usually attached to the ceiling of the rooms whose resonance is to be reduced. They can also be used to coat all the walls of the room. FR-A-2 748 505 discloses a sound and heat absorption panel comprising a perforated wood sheet bonded to a textile layer, itself bonded to a layer of mineral wool, that is to say of wool glass or rockwool. Alternatively, the wood sheet is of sufficient thickness to be glued directly to the mineral wool layer without requiring the presence of a textile layer. The rigidity of such a panel is obtained on the one hand, by the thickness of the mineral wool layer and, on the other hand, by the thickness of the wood coating or the textile layer bonded to it. Also known from FR-A-2 859 492 is a rock wool panel coated on the visible face of a laminated and perforated wood plate and, on the rear face, another laminated wood plate allowing the stiffening of the sign.
De tels panneaux sont donc d'une épaisseur relativement importante, ce qui induit des problèmes d'encombrement et de poids lorsqu'ils sont mis en place sur un plafond. La nature du matériau utilisé pour la plaque perforée, à savoir du bois stratifié, ne permet pas de satisfaire aux conditions de tenue au feu qui doivent, dorénavant, être respectées pour ce type de produit. De plus, la plaque perforée en bois est sujette à des variations dimensionnelles dues notamment aux variations d'hygrométrie et de température de la pièce et/ou de l'atelier de fabrication.Such panels are therefore of a relatively large thickness, which induces problems of size and weight when they are placed on a ceiling. The nature of the material used for the perforated plate, namely laminated wood, does not meet the fire resistance conditions which must, from now on, be respected for this type of product. In addition, the wooden perforated plate is subject to dimensional variations due in particular to variations in hygrometry and temperature of the room and / or the manufacturing workshop.
On connaît également par EP-A-524 566 et par DE-U-84 37 685 des panneaux comprenant une plaque perforée en matériau métallique. De tels panneaux restent relativement lourdsEP-A-524 566 and DE-U-84 37 685 also disclose panels comprising a perforated plate made of metallic material. Such panels remain relatively heavy
C'est à ces inconvénients qu'entend remédier l'invention en proposant un panneau de correction acoustique, peu encombrant, léger et résistant au feu, tout en ayant une rigidité importante et une résistance au voilage lors des écarts de température et d'humidité rencontrés dans la pièce.It is these drawbacks that the invention intends to remedy by proposing an acoustic correction panel that is compact, lightweight and resistant to damage. fire, while having a high rigidity and a resistance to the veiling at the temperature and humidity differences encountered in the room.
A cet effet, l'invention a pour objet un panneau de correction acoustique comprenant une couche en matériau absorbant fixée à une plaque perforée réalisée en métal formant la face visible du panneau lorsque celui-ci est en place dans une pièce, caractérisé en ce que les perforations occupent au moins 20% de l'aire de la face visible de la plaque perforée et en ce que la face visible de la plaque perforée est revêtue d'un motif décoratif.d'une épaisseur comprise entre 70 et 100 microns.For this purpose, the subject of the invention is an acoustic correction panel comprising a layer of absorbent material attached to a perforated plate made of metal forming the visible face of the panel when it is in place in a room, characterized in that the perforations occupy at least 20% of the area of the visible face of the perforated plate and in that the visible face of the perforated plate is coated with a decorative pattern of thickness between 70 and 100 microns.
L'utilisation d'une plaque métallique permet, pour des épaisseurs relativement faibles, de réaliser un panneau rigide, insensible aux conditions d'humidité et de température, tout en présentant une tenue au feu supérieure à celle des panneaux en bois stratifié.The use of a metal plate allows, for relatively small thicknesses, to achieve a rigid panel, insensitive to moisture and temperature conditions, while having a fire resistance higher than that of laminated wood panels.
Selon des aspects avantageux mais non obligatoires de l'invention, le panneau peut incorporer une ou plusieurs des caractéristiques suivantes :According to advantageous but non-mandatory aspects of the invention, the panel may incorporate one or more of the following features:
- La plaque perforée est réalisée en aluminium, notamment en aluminium de nuances normalisées EN AW-5754 (AIMg3) H111 ou H12, ou en alliage d'aluminium.- The perforated plate is made of aluminum, including aluminum grades standardized EN AW-5754 (AIMg3) H111 or H12, or aluminum alloy.
- La plaque perforée a une épaisseur comprise entre 0,7 et 1 mm.- The perforated plate has a thickness between 0.7 and 1 mm.
- Les perforations de la plaque perforée ont un diamètre d'environ 2 mm et sont régulièrement espacées d'environ 5 mm.The perforations of the perforated plate have a diameter of about 2 mm and are regularly spaced about 5 mm.
- La couche en matériau absorbant est formée de laine minérale, notamment de la laine de roche.- The layer of absorbent material is formed of mineral wool, including rock wool.
- La couche en laine minérale a une épaisseur (E) comprise entre 15 et 25 mm.- The mineral wool layer has a thickness (E) of between 15 and 25 mm.
L'invention concerne également un plafond d'une pièce qui est équipé d'au moins un panneau de correction acoustique tel que mentionné ci- dessus. Un tel plafond est plus sûr que ceux de l'état de la technique, alors qu'il est économique.The invention also relates to a ceiling of a room which is equipped with at least one acoustic correction panel as mentioned above. Such a ceiling is safer than those of the state of the art, while it is economical.
L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre d'un mode de réalisation d'un panneau conforme à l'invention, donnée uniquement à titre d'exemple faite et en se référant aux dessins annexés dans lesquels :The invention will be better understood and other advantages thereof will appear more clearly on reading the following description of an embodiment of a panel according to the invention, given only by way of example and with reference to the accompanying drawings in which:
- la figure 1 est une vue en perspective d'un panneau conforme à l'invention etFIG. 1 is a perspective view of a panel according to the invention and
- la figure 2 est une vue partielle, de face et à plus grande échelle, d'un détail du panneau de la figure 1.- Figure 2 is a partial view, front and on a larger scale, of a detail of the panel of Figure 1.
Le panneau 1 représenté à la figure 1 correspond à une dalle carrée d'environ 600 mm par 600 mm de côté, du type de celles généralement utilisées pour réaliser des plafonds dits « acoustiques », c'est-à-dire des plafonds évitant ou limitant la réverbération d'ondes sonores.The panel 1 shown in Figure 1 corresponds to a square slab of about 600 mm by 600 mm side, of the type commonly used to achieve so-called "acoustic" ceilings, that is to say ceilings avoiding or limiting the reverberation of sound waves.
Dans d'autres modes de réalisation non illustrés, le panneau a des formes et des dimensions différentes. Par exemple, il peut être rectangulaire.In other non-illustrated embodiments, the panel has different shapes and dimensions. For example, it can be rectangular.
Le panneau 1 comprend une couche centrale 2 formant l'âme du panneau. Cette couche centrale 2 est réalisée à partir d'un matériau absorbant du point de vue acoustique et qui est ininflammable. Il s'agit, en pratique, de matériau du type laine minérale. Par le terme « laine minérale » on entend un matériau réalisé à partir de fibres de verre ou de roche, par exemple de la laine de roche réalisée à partir de fibres d'origine volcanique. Ce matériau absorbant peut être du type « laine » c'est-à-dire avec des fibres entrelacées, sans aucun arrangement prédéterminé, ou avec des fibres dont l'orientation est préalablement définie, par exemple tissé ou non tissé.The panel 1 comprises a central layer 2 forming the core of the panel. This central layer 2 is made from an acoustically absorbing material which is non-flammable. This is, in practice, mineral wool type material. By the term "mineral wool" is meant a material made from glass or rock fibers, for example rock wool made from fibers of volcanic origin. This absorbent material may be of the "wool" type, that is to say with intertwined fibers, without any predetermined arrangement, or with fibers whose orientation is previously defined, for example woven or non-woven.
Le matériau absorbant a une densité comprise entre 100 et 135 kilos au m3. On réalise une couche centrale ou âme 2 d'une épaisseur E comprise entre 15 et 25 mm. Cette couche centrale 2 est avantageusement recouverte d'un film 3, par exemple, un voile en un matériau ignifugé, tel que de la fibre de verre. Ce voile 3, représenté pour plus de lisibilité sur la seule face arrière du panneau 1 à la figure 1 , permet, d'une part, d'éviter la dispersion des particules de laine minérale dans la pièce avant la pose et, d'autre part, participe à la finition du panneau. La face 5 du panneau 1 destinée à être orientée vers l'intérieur de la pièce, et dénommée « face visible », correspond à la face que voit un utilisateur lorsque la dalle 2 est en place dans un plafond.The absorbent material has a density between 100 and 135 kg per m 3. A central layer or core 2 having a thickness E of between 15 and 25 mm is produced. This central layer 2 is advantageously covered with a film 3, for example, a web of flame retardant material, such as fiberglass. This web 3, shown for more legibility on the only rear face of the panel 1 in Figure 1, allows, on the one hand, to prevent the dispersion of the mineral wool particles in the room before installation and other on the other hand, participates in finishing the panel. The face 5 of the panel 1 intended to be oriented towards the interior of the room, and referred to as "visible face", corresponds to the face that a user sees when the slab 2 is in place in a ceiling.
Cette face 5 est formée par une face d'une plaque de métal 4. Cette plaque de métal 4 est, dans l'exemple, réalisée à partir d'aluminium de nuances normalisées EN AW-5754 (AIMg3) H111 ou H 12. Elle confère une bonne rigidjté de la plaque 4, même avec une épaisseur faible. En variante, elle peut être réalisée en un autre métal, par exemple en alliage d'aluminium ou, en acier. Cette plaque 4 a une épaisseur e comprise entre 0,7 et 1 mm. Ainsi, pour une plaque carrée de 600 mm de côté, son poids est de l'ordre de 2 kg.This face 5 is formed by a face of a metal plate 4. This metal plate 4 is, in the example, made from aluminum of standardized grades AW AW-5754 (AIMg3) H111 or H 12. It gives a good rigidity of the plate 4, even with a small thickness. Alternatively, it may be made of another metal, for example aluminum alloy or steel. This plate 4 has a thickness e of between 0.7 and 1 mm. Thus, for a square plate of 600 mm side, its weight is of the order of 2 kg.
Elle peut être recouverte d'un ou plusieurs motifs décoratifs reproduisant, par exemple, l'aspect du bois ou du marbre, un motif géométrique ou de couleur. Sur une plaque 4 en aluminium, les motifs décoratifs sont réalisés à l'aide de peintures à base de poudres polyester appliquées avec des techniques connues en soi. De préférence, une épaisseur de 70 à 100 microns de peinture ou de revêtement décoratifsur la plaque 4 permet de réaliser des décors à façon sur la face visible 5 de la plaque 4, tout en satisfaisant aux normes de tenue au feu.It can be covered with one or more decorative motifs reproducing, for example, the appearance of wood or marble, a geometric pattern or color. On an aluminum plate 4, the decorative patterns are made using paints based on polyester powders applied with techniques known per se. Preferably, a thickness of 70 to 100 microns of paint or decorative coating on the plate 4 makes it possible to create decorations on the visible face 5 of the plate 4, while meeting the standards of fire resistance.
Au moins 20% de l'aire de la face 5 de la plaque 4 est constitué de perforations 6. Ces perforations 6 permettent le passage du son en direction de la couche centrale 2 de laine minérale qui absorbe, au moins partiellement, le son et réduit ainsi le phénomène de résonance dans la pièce.At least 20% of the area of the face 5 of the plate 4 consists of perforations 6. These perforations 6 allow the passage of sound towards the central layer 2 of mineral wool which absorbs, at least partially, the sound and thus reduces the resonance phenomenon in the room.
Les perforations 6 sont traversantes et circulaires. Elles ont un diamètre D d'environ 2 mm et sont régulièrement espacées. Avantageusement, entre deux perforations 6 voisines, une distance d d'environ 5 mm est ménagée.The perforations 6 are through and circular. They have a diameter D of about 2 mm and are regularly spaced. Advantageously, between two perforations 6 neighbors, a distance d of about 5 mm is formed.
Il est possible, selon les besoins et l'effet esthétique recherché, de ménager une zone pleine entre le bord de la plaque 4 et les perforations 6. La largeur de cette zone ou marge 7 est variable selon la dalle 1 envisagée.It is possible, depending on the needs and the desired aesthetic effect, to provide a solid area between the edge of the plate 4 and the perforations 6. The width of this zone or margin 7 is variable according to slab 1 envisaged.
Les perforations 6 peuvent être de forme, de dimensions et en nombre autres que ceux décrits. Par exemple, on peut prévoir des perforations en forme de fentes, de losanges, de carrés ou d'autres motifs répartis différemment sur la plaque 4. Ces perforations ne doivent pas, remettre en cause la surface minimale perforée de la plaque 4 qui est de 20 %.The perforations 6 may be of shape, size and number other than those described. For example, perforations can be provided in slits, diamonds, squares or other patterns distributed differently on the plate 4. These perforations should not, question the minimum perforated surface of the plate 4 which is 20%.
La plaque 4 permet de réaliser un panneau 1 de dimensions constantes qui n'est pas sujet au voilage. En effet, une telle plaque est d'une grande stabilité, tant dimensionnelle que dans le temps, et présente une tenue au feu lui permettant d'obtenir le classement Euro Classe B.The plate 4 makes it possible to produce a panel 1 of constant dimensions which is not subject to curl. Indeed, such a plate is of great stability, both dimensional and in time, and has a fire resistance allowing it to obtain the classification Euro Class B.
De plus, avec une plaque 4 en aluminium ou en alliage d'aluminium, il est aisé de découper sur site les plaques aux dimensions voulues pour les adapter à la taille du plafond ou des cloisons à recouvrir et de réaliser aisément des perforations 6 dans la plaque, sans bavure qui nuirait à la planéité de la plaque.In addition, with a plate 4 made of aluminum or aluminum alloy, it is easy to cut on site the plates to the desired dimensions to fit the size of the ceiling or partitions to cover and easily make perforations 6 in the plate, without burr that would harm the flatness of the plate.
La fixation de la couche centrale sur la plaque s'effectue avantageusement par collage. Fixing the central layer on the plate is advantageously carried out by gluing.
