ELEMENT DE CONSTRUCTION POUR ISOLATION ACOUSTIQUEBUILDING ELEMENT FOR SOUND INSULATION
La présente invention concerne un élément de construction The present invention relates to a building element
pour isolation acoustique du genre panneau perforé ou ajouré. for acoustic insulation such as perforated or perforated panels.
Depuis longtemps sont déjà connus des éléments de construction qui sont sous la forme de plaques perforées ou ajourées en t 6 les minces ou matériaux analogues et qui sont doublés à l'intérieur par un matelas de feutre en laine de verre ou en laine de roche en tant qu'assemblage insonorisant sous Construction elements which have been in the form of perforated or perforated t 6 plates for a long time have already been known as thin or similar materials and which are lined on the inside with a felt mat of glass wool or rock wool. as a sound-absorbing assembly under
plafond à l'intérieur de locaux.ceiling inside premises.
L'insonorisation par de tels éléments dépend de différentes circonstances et particulièrement d'abord de la section transversale dite libre des plaques ainsi que de la proportion de trous par rapport à la surface totale de plaque, de l'épaisseur du feutre absorbant appliqué et de la distance entre l'assemblage insonorisant et le plafond en oeuvre de la construction ayant un The soundproofing by such elements depends on different circumstances and particularly first of the so-called free cross section of the plates as well as the proportion of holes relative to the total surface of the plate, the thickness of the absorbent felt applied and the distance between the sound-absorbing assembly and the ceiling in construction having a
indice d'affaiblissement faible.weak weakening index.
Les installations d'insonorisation en laine de verre ou en laine de roche ne sont pas onéreuses, mais par contre, le coût de travaux de montage réalisés en chantier pour appliquer le feutre d'insonorisation au plafond est comparativement plus élevé puisque Glass wool or rock wool soundproofing installations are not expensive, but on the other hand, the cost of assembly work carried out on site to apply the soundproofing felt to the ceiling is comparatively higher since
les rémunérations des ouvriers doivent être prises en compte. workers' remuneration must be taken into account.
La manipulation du feutre d'insonorisation est en outre quelque peu désagréable et dans certaines conditions est également malsaine chaque fois que de petites fibres de la laine de verre ou de la laine de roche sont très cassantes et peuvent, suite à la manipulation, pénétrer facilement dans la peau des mains et ainsi former des plaies En outre, les fibres occasionnent des The handling of the soundproofing felt is also somewhat unpleasant and under certain conditions is also unhealthy whenever small fibers of glass wool or rock wool are very brittle and can, after handling, easily penetrate in the skin of the hands and thus form sores In addition, the fibers cause
irritations nasales, buccales et pharyngées. nasal, oral and pharyngeal irritations.
Par ailleurs, pour fabriquer les différents feutres d'insonorisation, les matériaux de base doivent être fondus, ce qui nécessite une consommation énergétique élevée, et doivent être Furthermore, to make the different soundproofing felts, the basic materials must be melted, which requires high energy consumption, and must be
préparés en fibres minces selon des procédés très complexes. prepared in thin fibers according to very complex processes.
-2- L'invention a ainsi pour but de fournir un élément de construction pour isolation acoustique du genre panneau perforé ou -2- The object of the invention is therefore to provide a construction element for acoustic insulation of the perforated panel type or
ajouré, ne présentant pas les inconvénients précédents. openwork, not having the above drawbacks.
A cette fin, un élément de construction pour isolation acoustique du genre panneau perforé ou ajouré est caractérisé en ce qu'un paillasson de fibre est appliqué sur le panneau de sorte que le paillasson de fibre soit indétachable en tout point du panneau et soit tendu au-dessus des trous du panneau comme la peau To this end, a building element for acoustic insulation of the perforated or perforated panel type is characterized in that a fiber mat is applied to the panel so that the fiber mat is non-detachable at all points of the panel and is stretched to the - over panel holes like skin
d'un tambour.of a drum.
Selon une autre caractéristique de l'invention, le paillasson de fibre tendu comme la peau d'un tambour cause au niveau des trous du panneau une résistance à l'écoulement accrue qui définit la capacité -d'absorption acoustique désirée de l'élément de construction. Selon une autre caractéristique de l'invention, la résistance à l'écoulement agissant sur l'isolation acoustique est créée par la section dite libre de l'élément de construction, c'est-à-dire en fonction du nombre et du diamètre des trous dans le panneau et dépend de la densité du paillasson de fibre qui est supporté par l'élément de construction et dont les fibres sont contraintes According to another characteristic of the invention, the fiber mat stretched like the skin of a drum causes an increased flow resistance at the level of the holes in the panel which defines the desired sound absorption capacity of the element of construction. According to another characteristic of the invention, the resistance to flow acting on the acoustic insulation is created by the so-called free section of the construction element, that is to say as a function of the number and the diameter of the holes in the panel and depends on the density of the fiber mat that is supported by the building element and whose fibers are stressed
comme la peau d'un tambour, au niveau des trous. like the skin of a drum, at the level of the holes.
Selon une autre caractéristique de l'invention, la résistance à l'écoulement de l'élément est influençable par une modification de la compacité du paillasson de fibre La modification de la compacité du paillasson de fibre est obtenue en appliquant un According to another characteristic of the invention, the resistance to flow of the element can be influenced by a modification of the compactness of the fiber mat. The modification of the compactness of the fiber mat is obtained by applying a
matériau de colmatage adéquat.adequate sealing material.
Selon une autre caractéristique de l'invention, l'effet d'isolation acoustique à obtenir de l'élément est obtenu en modifiant la résistance totale à l'écoulement de l'élément de construction. Selon une autre caractéristique de l'invention, le panneau perforé ou ajouré est mince et est en métal, bois, carton, matière plastique ou analogue, le panneau étant uni en un ensemble unitaire à un paillasson de fibre poreux à mailles fines présentant une résistance à l'écoulement définie, et le paillasson 3 - de fibre a des fibres croisées au-dessus des trous du panneau et According to another characteristic of the invention, the acoustic insulation effect to be obtained from the element is obtained by modifying the total resistance to flow of the building element. According to another characteristic of the invention, the perforated or perforated panel is thin and is made of metal, wood, cardboard, plastic or the like, the panel being joined in a unitary assembly to a porous fiber mat of fine mesh having a resistance at defined flow, and the fiber mat 3 - has fibers crossed over the panel holes and
tendues au-dessus de ceux-ci comme la peau d'un tambour. stretched over them like the skin of a drum.
Selon une autre caractéristique de l'invention, la résistance à l'écoulement du paillasson de fibre poreux à mailles fines est ajustable dans la zone des tensions des fibres au-dessus des trous comme celle de la peau d'un tambour par le fait que le paillasson According to another characteristic of the invention, the resistance to flow of the porous doormat of fine-meshed fiber is adjustable in the region of the tensions of the fibers above the holes like that of the skin of a drum by the fact that the mat
est comprimé par application de matériaux adéquats. is compressed by applying suitable materials.
Selon une autre caractéristique de l'invention, la résistance à l'écoulement de l'élément est déterminée par modification de la section dite libre du panneau perforé ou -ajouré ou par modification de la résistance à l'écoulement du paillasson de fibre tendu en le recouvrant d'un agent adhésif remplissant According to another characteristic of the invention, the resistance to flow of the element is determined by modification of the so-called free section of the perforated or perforated panel or by modification of the resistance to flow of the tensile fiber mat in covering it with a filling agent
incomplètement les pores du paillasson de fibre. partially the pores of the fiber mat.
Enfin, selon une autre caractéristique de l'invention, le paillasson de fibre influençant la résistance à l'écoulement de l'élément est appliqué sur la face arrière de l'élément de construction, et la face avant visible de l'élément de construction est une surface traitée classiquement, telle qu'une Finally, according to another characteristic of the invention, the fiber mat influencing the flow resistance of the element is applied to the rear face of the construction element, and the visible front face of the construction element is a conventionally treated surface, such as a
surface laquée.lacquered surface.
En raison de lois physiques peu considérées jusqu'à présent, la résistance à l'écoulement du feutre d'isolation acoustique utilisé antérieurement peut ici être obtenue selon l'invention et être mise au point en fonction du rendement nécessaire pour la construction, en reliant des panneaux minces perforés, de préférence en tôle, à des matériaux poreux tels que par exemple du papier, des paillassons ou des textiles de sorte qu'au niveau des trous des panneaux, ces matériaux soient tendus comme la peau d'un tambour La résistance à l'écoulement définissable ainsi créée peut être ajustée d'une manière quelconque en appliquant des Due to physical laws little considered until now, the resistance to flow of the previously used acoustic insulation felt can here be obtained according to the invention and be developed as a function of the yield necessary for construction, by connecting thin perforated panels, preferably sheet metal, to porous materials such as for example paper, doormats or textiles so that at the level of the holes in the panels, these materials are stretched like the skin of a drum Resistance to the definable flow thus created can be adjusted in any way by applying
matériaux de remplissage sur le paillasson. filling materials on the mat.
Une diminution des coûts de fabrication des éléments de construction selon l'invention résulte particulièrement du fait que ces éléments de construction sont déjà mis au point au cours du processus de fabrication industrielle en fonction des conditions ambiantes acoustiques propres comme cela est nécessaire A reduction in the manufacturing costs of the construction elements according to the invention results particularly from the fact that these construction elements are already developed during the industrial manufacturing process as a function of the own acoustic ambient conditions as necessary.
pour les travaux en chantier.for site work.
-4- L'effet d'isolation acoustique de l'élément de construction selon l'invention est obtenu grâce au fait qu'au niveau des trous sollicités en tension par le paillasson de fibre comme une peau de tambour est créée une résistance à l'écoulement définissable qui inhibe, par définition acoustique et mathématique, le bruit perturbateur sur une étendue déterminable Les trous dans le panneau présentent un effet analogue à celui d'ajutages qui est encore amplifié par le paillasson de fibre appliqué Le paillasson de fibre compriment la perforation du panneau Cet effet analogue à celui d'ajutage est ainsi en liaison directe avec la diminution -4- The acoustic insulation effect of the building element according to the invention is obtained thanks to the fact that at the level of the holes stressed in tension by the fiber mat like a drum skin is created resistance to definable flow which inhibits, by acoustic and mathematical definition, the disturbing noise over a determinable extent The holes in the panel have an effect similar to that of nozzles which is further amplified by the applied fiber mat The fiber mat compresses the perforation of the panel This effect, similar to that of the nozzle, is thus directly linked to the reduction
du niveau 'de bruit dans le local.the noise level in the room.
Lors d'ajustement significatif du paillasson de fibre tendu comme une peau de tambour, la résistance à-l'écoulement peut être surélevée et par suite, l'isolation acoustique (facteur d'absorption acoustique) peut être modifiée dans des bandes de When the fiber mat stretched like a drum skin is significantly adjusted, the resistance to flow can be raised and, as a result, the sound insulation (sound absorption factor) can be changed in bands of
fréquence déterminées.frequency determined.
Cet ajustement peut être obtenu par exemple en projetant des substances de colmatage sur le paillasson de fibre Ces substances de colmatage rétrécissent les interstices entre les fibres du This adjustment can be obtained for example by spraying blocking substances on the fiber mat. These blocking substances narrow the interstices between the fibers of the fiber.
paillasson et réduisent par conséquent le flux d'écoulement. mat and therefore reduce the flow of flow.
En modifiant la section libre des trous de l'élément de construction et en traitant en conséquence le paillasson à fibres croisées au-dessous des trous peut être obtenu facilement l'isolement acoustique correspondant à celui d'une installation acoustique classique à laine de roche ou laine de verre ayant une épaisseur de 30 mm L'élément de construction selon l'invention a de préférence une épaisseur inférieure à 1 mm, bien que le résultat obtenu soit analogue, voire meilleur que celui d'une plaque d'isolation acoustique classique ayant un matelas absorbant By modifying the free cross-section of the holes in the building element and treating the cross-fiber mat underneath the holes accordingly, the sound insulation corresponding to that of a conventional rock wool acoustic installation can be easily obtained. glass wool having a thickness of 30 mm The construction element according to the invention preferably has a thickness of less than 1 mm, although the result obtained is similar to, or even better than, that of a conventional acoustic insulation plate having an absorbent mattress
de 30 mm en laine de verre ou laine de roche. of 30 mm in glass wool or rock wool.
