Description

La présente invention a pour objet un panneau d'isolation thermo-acoustique pour des bâtiments, comme par exemple des bâtiments industriels ou analogues, et des procédés de fabrication d'un tel panneau.The present invention relates to a panel thermo-acoustic insulation for buildings, such as for example industrial or similar buildings, and methods of manufacturing such a panel.

Lors de la construction des bâtiments comme par exemple des bâtiments industriels,commerciaux ou de loisirs, il est connu d'utiliser pour les parois verticales et/ou la couverture, des panneaux qui doivent satisfaire à différentes contraintes et notamment à des contraintes mécaniques, d'isolation thermique, d'isolation acoustique et hygrométriques intégrant les problèmes de condensation et de l'ambiance de l'air dans les locaux.When constructing buildings like for example industrial, commercial or commercial buildings leisure it is known to use for vertical walls and / or the cover, panels which must meet various constraints and in particular mechanical stress, thermal insulation, insulation acoustic and hygrometric integrating the problems of condensation and the atmosphere of the air in the local.

L'isolation acoustique doit permettre, par absorption acoustique, de diminuer la transmission directe du bruit d'un local à l'autre et de réduire la réverbération du bruit sur les parois d'un local donné et donc de diminuer le niveau sonore à l'intérieur de ce local.The sound insulation must allow, for sound absorption, decrease transmission direct noise from one room to another and reduce the noise reverberation on the walls of a given room and therefore decrease the noise level inside this local.

Pour cela, on connaít les panneaux d'isolation thermo-acoustique qui sont constitués d'un parement extérieur métallique plein et profilé, d'un parement intérieur métallique comportant des zones perforées et d'une âme en matériau d'isolation thermique remplissant l'espace entre les deux parements pour obtenir les performances requises de rigidité mécanique du panneau.For this, we know the insulation panels thermo-acoustic which consist of a facing solid, profiled metal exterior with siding metallic interior with perforated areas and of a core of thermal insulation material filling the space between the two facings to obtain the required performance of mechanical rigidity of the panel.

D'autre part, l'âme comporte, au regard des zones perforées du parement métallique intérieur, des plaques d'isolation acoustique.On the other hand, the soul includes, with regard to perforated areas of the interior metal facing, sound insulation plates.

Le parement extérieur comporte des nervures plus ou moins profondes en fonction de l'utilisation du panneau, comme panneau de couverture ou comme panneau de bardage. The outer facing has ribs more or less deep depending on the use of the panel, as a cover panel or as a panel cladding.

Mais, ce type de panneaux d'isolation thermo-acoustique présente des inconvénients.But, this type of thermo-acoustic insulation panels has drawbacks.

La résistance mécanique de ce genre de panneaux, notamment lorsqu'ils sont utilisés comme panneaux de couverture, n'est pas suffisante.The mechanical resistance of this kind of panels, especially when used as cover panels, is not sufficient.

En effet, les matériaux généralement utilisés pour les plaques d'isolation acoustique sont souples si bien que la portée du parement intérieur sur l'âme n'est rigidement assurée qu'au regard des zones non perforées de ce parement intérieur, ce qui diminue la rigidité du panneau et conduit en pratique à limiter la surface des zones perforées et de ce fait des plaques d'isolation acoustique.Indeed, the materials generally used for sound insulation plates are flexible if although the range of the interior facing on the core is not rigidly ensured that with regard to the non-perforated areas of this interior facing, which reduces the rigidity of the panel and leads in practice to limit the surface of the perforated areas and therefore insulation plates acoustic.

Ainsi, non seulement la rigidité du panneau est réduite, mais les performances d'isolation acoustique sont limitées.So, not only the rigidity of the panel is reduced, but the sound insulation performance are limited.

Par ailleurs, en période hivernale l'âme d'isolation thermique sépare une zone froide extérieure d'une zone chaude intérieure.In addition, in winter the soul of thermal insulation separates an external cold zone an indoor hot zone.

Entre ces deux ambiances de caractéristiques différentes séparées par un matériau isolant, il existe une différence de pression de vapeur d'eau qui est l'élément moteur de la migration de la vapeur. Ce phénomène de transfert se fait en hiver de la face intérieure vers la face extérieure.Between these two atmospheres of characteristics different separated by insulating material, there are a difference in water vapor pressure which is the driving force behind vapor migration. This transfer phenomenon occurs in winter from the inside face towards the outside face.

Lors de ce transfert, la vapeur s'accumule et se condense dans les zones froides.During this transfer, the steam accumulates and condenses in cold areas.

Ainsi, si l'atmosphère intérieure pénètre dans l'âme d'isolation thermique, ce qui est le cas des panneaux poreux, on assiste à des condensations d'eau dans cette âme ce qui provoque une augmentation de la perméabilité, une chute des performances mécaniques, des variations dimensionnelles et l'apparition de corrosion sur la face supérieure des parements intérieurs.So if the interior atmosphere enters in the thermal insulation core, which is the case for porous panels, we are witnessing water condensations in this soul which causes an increase in the permeability, a drop in mechanical performance, dimensional variations and the appearance of corrosion on the upper side of the interior facings.

De plus, lors de la fabrication de ces panneaux d'isolation thermo-acoustique, outre la nécessité de profiler une bande métallique perforée pour le parement intérieur, il importe d'assurer la pose des plaques d'isolation acoustique sur la face interne des zones perforées de la bande avant l'injection de la composition à polymériser et à mousser destinée à former l'âme.In addition, during the manufacture of these thermal-acoustic insulation panels, in addition to the need to profile a perforated metal strip for the interior facing, it is important to ensure the installation of acoustic insulation plates on the internal face of perforated areas of the strip before injecting the polymerization and foaming composition for forming blade.

Cette exigence conduit à organiser la production avec la bande formant le parement intérieur en bas et donc avec la bande formant le parement extérieur en haut de telle manière que les plaques d'isolation acoustique, simplement posées sur les zones perforées, s'y maintiennent par simple gravité jusqu'au moussage complet de la composition formant l'âme.This requirement leads to organizing the production with the strip forming the interior facing at the bottom and therefore with the strip forming the outer facing at the top so that the insulation plates acoustic, simply placed on the perforated areas, are maintained there by simple gravity until complete foaming of the composition forming the core.

Or, lorsque le parement extérieur présenté des nervures profondes, notamment dans le cas de panneaux de couverture, la composition à polymériser et à mousser ne pénètre pas complètement dans le fond des nervures en moussant.However, when the exterior facing presented deep ribs, especially in the case of panels cover, the composition to polymerize and foam does not fully penetrate the bottom of the ribs in foaming.

Il se crée donc entre le parement extérieur et l'âme des zones vides ce qui entraíne un mauvaise isolation thermique et de mauvaises propriétés mécaniques.It is therefore created between the exterior facing and the soul of the empty areas which results in bad thermal insulation and poor mechanical properties.

Enfin, ce type de panneaux d'isolation thermo-acoustique nécessite des opérations successives de pose des différents composants et des matériaux qui sont souvent mal maítrisées ce qui provoque des dispersions importantes quant aux résultats et performances obtenus.Finally, this type of insulation panels thermo-acoustic requires successive operations installation of the various components and materials which are often poorly controlled which causes dispersions important in terms of results and performance obtained.

L'invention a pour but d'éviter ces inconvénients en proposant un panneau d'isolation thermo-acoustique qui permet de résoudre les problèmes de complémentarités des performances acoustiques, hygrothermiques et mécaniques, tout en simplifiant les procédés de fabrication et en facilitant la pose.

Sur les figures, on a représenté schématiquement un panneau d'isolation thermo-acoustique désigné dans son ensemble par la référence 1 et qui est destiné à être utilisé par exemple comme panneau de couverture ou comme panneau de bardage dans des bâtiments, notamment des bâtiments industriels, des salles de loisirs ou de sport ou dans des locaux commerciaux.The figures show schematically a designated thermal-acoustic insulation panel as a whole by the reference 1 and which is intended to be used for example as a cover panel or as a cladding panel in buildings, in particular industrial buildings, recreation rooms or sports or commercial premises.

D'une manière générale, le panneau d'isolation 1 comprend un parement métallique extérieur 2, par exemple en acier ou en aluminium, un parement métallique intérieur 3, par exemple en acier ou en aluminium et une âme 4 en matériau isolant insérée entre lesdits parements métalliques 2 et 3.Generally speaking, the insulation panel 1 includes an exterior metal facing 2, by example in steel or aluminum, a metal facing interior 3, for example steel or aluminum and a core 4 of insulating material inserted between said facings metallic 2 and 3.

Lorsque le panneau d'isolation 1 est utilisé comme panneau de couverture, le parement extérieur métallique 2 est muni de nervures 5 en saillie qui permettent de rigidifier ce parement extérieur 2.When insulation panel 1 is used as a cover panel, the exterior facing metal 2 is provided with projecting ribs 5 which allow this external facing 2 to be stiffened.

Ainsi que représenté sur les figures 1 à 5, le parement extérieur 2 comporte, sur l'un de ses bords longitudinaux, un recouvrement longitudinal 2a appelé "nervure libre" s'étendant sur toute la longueur de ce bord et qui est profilé selon une forme correspondant à la forme de la bordure du panneau d'isolation 1 adjacent.As shown in Figures 1 to 5, the outer facing 2 has, on one of its edges longitudinal, a longitudinal overlap 2a called "free rib" extending over the entire length of this edge and which is shaped in a shape corresponding to the shape of the edge of the adjacent insulation panel 1.

Ainsi, le recouvrement longitudinal 2a constitue un élément de réception du panneau d'isolation 1 adjacent ce qui permet de pouvoir positionner les panneaux les uns à côté des autres pour réaliser une surface continue.Thus, the longitudinal overlap 2a is an element for receiving the insulation panel 1 adjacent which allows you to position the panels next to each other to achieve a continuous surface.

Un joint d'étanchéité 6 est interposé entre les panneaux d'isolation adjacents.A seal 6 is interposed between the adjacent insulation panels.

Lorsque le panneau d'isolation 1 est utilisé comme panneau de bardage, le parement extérieur métallique 2 comporte de légères nervures de rigidification.When insulation panel 1 is used as a cladding panel, the metallic exterior facing 2 has slight stiffening ribs.

Ainsi que représenté à la Fig. 7, le panneau d'isolation 1 présente, sur l'un de ses bords longitudinaux, un chant mâle 8 et, sur l'autre de ses bords longitudinaux, un chant femelle 9 ce qui permet un assemblage par emboítement et le positionnement des panneaux d'isolation 12 les uns à côté des autres pour réaliser une surface continue.As shown in FIG. 7, the panel insulation 1 present, on one of its longitudinal edges, a male edge 8 and, on the other of its longitudinal edges, a female song 9 which allows an assembly by fitting and positioning the panels insulation 12 next to each other to achieve a continuous surface.

Par conséquent, les panneaux d'isolation 1 sont solidarisés entre eux soit par recouvrement dans la version couverture, soit par emboítement dans la version bardage.Therefore, insulation panels 1 are joined together either by overlapping in the cover version, either by nesting in the version cladding.

Les parements extérieurs et intérieurs, respectivement 2 et 3, sont solidarisés entre eux par exemple par emboítement ou par soudage.Exterior and interior siding, respectively 2 and 3, are joined together by example by interlocking or welding.

L'âme 4 en matériau isolant est réalisée en un matériau isolant rigide et est solidaire respectivement du parement métallique extérieur 2 et du parement métallique intérieur 3.The core 4 of insulating material is made of rigid insulating material and is secured respectively of exterior metal facing 2 and facing metallic interior 3.

Cette âme 4 est formée par exemple par une mousse de polyuréthanne injectée entre les parements 2 et 3 ou est formée par au moins une plaque en laine minérale usinée et collée sur les parements métalliques 2 et 3. This core 4 is formed for example by a polyurethane foam injected between the facings 2 and 3 or is formed by at least one woolen plate mineral machined and bonded to metal siding 2 and 3.

La laine minérale est de la laine de verre ou de la laine de roche.Mineral wool is glass wool or rock wool.

La laine minérale pour l'âme 4 est de préférence utilisée lorsqu'il est recherché un traitement d'isolation acoustique renforcé ou un comportement au feu amélioré.Mineral wool for core 4 is preference used when seeking treatment reinforced sound insulation or fire behavior improved.

Ainsi que représenté sur les figures, le parement métallique intérieur 3 est plein et comporte au moins un logement 7 de positionnement d'au moins une plaque d'isolation acoustique 10.As shown in the figures, the interior metal facing 3 is full and has at least one housing 7 for positioning at least one sound insulation plate 10.

Dans les exemples de réalisation représentés sur les figures, le panneau intérieur métallique 3 comporte deux logements 7 parallèles et s'étendant sur toute la longueur du panneau d'isolation 1.In the example embodiments shown in the figures, the metallic interior panel 3 has two parallel housings 7 extending over the entire length of the insulation panel 1.

Ainsi, le parement intérieur 3 comporte des zones en saillie 3a formant des nervures de rigidification s'étendant de chaque côté des logements 7 et entre ces logements 7.Thus, the interior facing 3 includes protruding areas 3a forming stiffening ribs extending on each side of the housings 7 and between these housings 7.

Par ailleurs, chaque logement 7 est muni, à sa partie supérieure et de chaque côté, d'un rebord 3b horizontal formé sur le parement intérieur 3 permettant le maintien de chaque plaque d'isolation acoustique 10 correspondante, comme on le verra ultérieurement.Furthermore, each housing 7 is provided, at its upper part and on each side, a rim 3b horizontal formed on the interior facing 3 allowing maintaining each acoustic insulation plate 10 corresponding, as we will see later.

La plaque d'isolation acoustique 10 est formée par exemple par une mousse de polyuréthanne à cellules ouvertes ou est réalisée en laine minérale, comme de la laine de verre ou de la laine de roche.The sound insulation plate 10 is formed for example by a polyurethane foam open cells or is made of mineral wool, like glass wool or rock wool.

Chaque logement 7 est obturé par une peau de recouvrement 20 appliquée sur la plaque d'isolation acoustique 10 correspondante pour former une surface sensiblement lisse et continue avec les zones 3a du parement intérieur 3 situées autour des logements 7.Each housing 7 is closed by a skin of overlap 20 applied to the insulation plate corresponding acoustics 10 to form a surface substantially smooth and continuous with areas 3a of the interior facing 3 located around the housings 7.

De préférence, la peau de recouvrement 20 est perforée pour favoriser l'absorption acoustique.Preferably, the covering skin 20 is perforated to promote sound absorption.

Cette peau de recouvrement 20 peut être réalisée de différentes manières.This covering skin 20 can be done in different ways.

Selon un premier mode de réalisation représenté aux figures 1 et 2, la peau de recouvrement 20 pour chaque logement 7 est constituée d'une lamelle 21 métallique perforée, par exemple en acier ou en aluminium.According to a first embodiment shown in Figures 1 and 2, the covering skin 20 for each housing 7 consists of a strip 21 perforated metal, for example steel or aluminum.

La lamelle 21 recouvre la plaque d'isolation acoustique 10 et ses bords longitudinaux 21a sont profilés et coopèrent avec les rebords 3b du logement 7 de façon à assurer un positionnement par emboítement de la lamelle 21 dans le logement 7 correspondant et de ce fait un maintien de la plaque d'isolation acoustique 10 dans ce logement 7.Lamella 21 covers the insulation plate acoustic 10 and its longitudinal edges 21a are profiles and cooperate with the edges 3b of the housing 7 so as to ensure a positioning by nesting of the strip 21 in the corresponding housing 7 and from this holds the sound insulation plate 10 in this accommodation 7.

Selon une variante, la peau de recouvrement 20 pour chaque logement peut être réalisée sous la formé de plusieurs lamelles 21 métalliques et juxtaposées pour recouvrir la plaque d'isolation acoustique 10.According to a variant, the covering skin 20 for each housing can be realized in the form several metal lamellae 21 and juxtaposed for cover the sound insulation plate 10.

Cette peau de recouvrement 20 peut être pleine sur toute la surface ou présenter des perforations seulement sur une partie de sa surface.This covering skin 20 can be full over the entire surface or have perforations only on part of its surface.

Par ailleurs, la ou les lamelles 21 peuvent être fixées par collage sur la plaque d'isolation acoustique 10 correspondante.Furthermore, the lamella (s) 21 can be fixed by gluing on the insulation plate corresponding acoustic 10.

Selon une variante, la peau de recouvrement 20 peut se présenter sous la forme d'une feuille souple de revêtement par exemple de type kraft-aluminium perforée ou pleine.According to a variant, the covering skin 20 can be in the form of a flexible sheet coating for example of kraft-aluminum type perforated or solid.

Selon un second mode de réalisation représenté à la figure 3 et notamment lorsque la plaque d'isolation acoustique 10 est formée par une plaque rigide en laine minérale, la peau de recouvrement 20 est constituée par une feuille souple 22 de revêtement par exemple de type kraft-aluminium directement collée sur ladite plaque d'isolation acoustique 10.According to a second embodiment shown in Figure 3 and especially when the plate of sound insulation 10 is formed by a plate rigid in mineral wool, the covering skin 20 is constituted by a flexible sheet 22 of coating by example of kraft-aluminum type directly glued on said acoustic insulation plate 10.

La feuille souple 22 est soit perforée ou soit pleine.The flexible sheet 22 is either perforated or be full.

Dans ce cas, la plaque d'isolation acoustique 10 munie de la feuille souple 22 de revêtement est directement positionnée par emboítement dans le logement 7 correspondant.In this case, the sound insulation plate 10 provided with the flexible sheet 22 of coating is directly positioned by fitting into the housing 7 correspondent.

Ainsi que représenté à la figure 6, la plaque d'isolation acoustique 10 peut comporter au moins une entretoise 30 de rigidification par exemple en matière plastique. Cette entretoise 30 de rigidification peut également servir d'éléments de raccord lorsque la plaque d'isolation acoustique 10 est formée de plusieurs plaques placées dans un même logement 7.As shown in Figure 6, the plate sound insulation 10 may include at least one stiffening spacer 30 for example in material plastic. This stiffening spacer 30 can also serve as connecting elements when the plate of sound insulation 10 is made up of several plates placed in the same housing 7.

Selon un troisième mode de réalisation représenté à la figure 4, la plaque d'isolation acoustique 10 ménage avec au moins l'un des bords du logement 7 correspondant une gaine 25 de passage par exemple pour des tuyauteries ou des câbles électriques 26.According to a third embodiment shown in Figure 4, the sound insulation plate 10 cleaning with at least one of the edges of the housing 7 corresponding to a passage duct 25 for example for electrical piping or cables 26.

Selon un quatrième mode de réalisation représenté à la Fig.5, le parement métallique intérieur 3 comporte sur sa face en contact avec la plaque d'isolation acoustique 10 c'est à dire au niveau du logement 7, des nervures 3c en saillie formant avec ladite plaque d'isolation acoustique 10 au moins une veine d'air.According to a fourth embodiment shown in Fig. 5, the interior metal facing 3 has on its face in contact with the insulation plate acoustic 10, that is to say at the level of the housing 7, protruding ribs 3c forming with said plate sound insulation 10 at least one air stream.

Ces veines d'air permettent d'obtenir une meilleure absorption acoustique dans le domaine des fréquences graves, et les nervures 3c renforcent la résistance mécanique du parement intérieur 3.These air streams provide a better sound absorption in the field of low frequencies, and the 3c ribs reinforce the mechanical resistance of the interior facing 3.

Le panneau d'isolation thermo-acoustique 1 selon l'invention présente de nombreux avantages.The thermo-acoustic insulation panel 1 according to the invention has many advantages.

Tout d'abord, le panneau 1 présente une rigidité mécanique améliorée grâce à la forme très nervurée du parement intérieur 3 du fait de la présence des logements 7 et des zones 3a en saillie entre lesdits logements ce qui est particulièrement avantageux lorsque ce panneau est utilisé comme panneau de couverture. First, panel 1 presents a improved mechanical rigidity thanks to the very ribbed on the inside facing 3 due to the presence housings 7 and areas 3a projecting between said housing which is particularly advantageous when this panel is used as a cover panel.

En effet, les zones d'appui du panneau d'isolation 1 sur les éléments de la charpente correspondent aux zones 3a en saillie entre les logements 7 et la réaction d'appui exercée sur ces zones 3a est répartie sur une plus grande surface de l'âme 4 rigide et solidaire des parements 2 et 3.Indeed, the support areas of the panel of insulation 1 on the elements of the frame correspond to the zones 3a projecting between the housings 7 and the support reaction exerted on these zones 3a is distributed on a larger surface of the rigid and integral core 4 facing 2 and 3.

De plus, le panneau 1 ne présente aucun risque de condensation d'eau dans l'épaisseur de l'âme 4 en matériau isolant thermique étant donné que cette âme 4 est dotée d'un élément de recouvrement parfaitement étanche constitué par le parement intérieur 3.In addition, panel 1 has no risk of water condensation in the thickness of the core 4 made of thermal insulating material since this core 4 has a perfectly covering element waterproof formed by the interior facing 3.

En effet, en période hivernale l'âme 4 d'isolation thermique sépare une zone froide extérieure d'une zone chaude intérieure.Indeed, in winter the soul 4 of thermal insulation separates an external cold zone an indoor hot zone.

Entre ces deux ambiances de caractéristiques différentes séparées par un matériau isolant, il existe une différence de pression de vapeur d'eau qui est l'élément moteur de la migration de la vapeur.Between these two atmospheres of characteristics different separated by insulating material, there are a difference in water vapor pressure which is the driving force behind vapor migration.

Ce phénomène de transfert se fait en hiver de la face intérieure vers la face extérieure.This transfer phenomenon occurs in winter from the inside face towards the outside face.

Lors de ce transfert, la vapeur s'accumule et se condense dans les zones froides.During this transfer, the steam accumulates and condenses in cold areas.

Ainsi, si l'atmosphère intérieure pénètre dans l'âme 4 d'isolation thermique, ce qui est le cas des panneaux poreux, on assiste à des condensations d'eau dans cette âme ce qui provoque une augmentation de la perméabilité, une chute des performances mécaniques, des variations dimensionnelles et l'apparition de corrosion sur la face supérieure des parements intérieurs.So if the interior atmosphere enters in the thermal insulation core 4, which is the case for porous panels, we are witnessing water condensations in this soul which causes an increase in the permeability, a drop in mechanical performance, dimensional variations and the appearance of corrosion on the upper side of the interior facings.

Avec le panneau d'isolation thermo-acoustique selon l'invention, ces phénomènes sont totalement exclus car l'âme 4 est entourée d'une peau étanche constituée par le parement intérieur 3 et le parement extérieur 2.With thermo-acoustic insulation panel according to the invention, these phenomena are completely excluded because the core 4 is surrounded by a tight skin made up by the interior facing 3 and the exterior facing 2.

Ainsi, le panneau d'isolation acoustique 1 selon l'invention permet de concilier les problèmes de complémentarité des performances acoustiques, hygrothermiques et mécaniques.Thus, the acoustic insulation panel 1 according to the invention makes it possible to reconcile the problems of complementary acoustic, hygrothermal performance and mechanical.

Enfin, ce panneau d'isolation thermo-acoustique se présente sous la forme d'un produit prêt à l'emploi dont la mise en oeuvre est aisée et rapide et dont les performances dans le temps sont constantes.Finally, this thermo-acoustic insulation panel comes in the form of a product ready to use whose implementation is easy and quick and whose performance over time is constant.

Ce genre de panneaux d'isolation thermo-acoustique peut être fabriqué soit par un procédé continu ou soit par un procédé discontinu.This kind of thermo-acoustic insulation panels can be produced either by a continuous process or either by a batch process.

Dans le cas d'un procédé de fabrication en continu avec une âme 4 d'isolation thermique en mousse de polyuréthanne, le procédé consiste à profiler une première bande métallique destinée à forme le parement extérieur 2, à profiler une seconde bande métallique destinée à former le parement intérieur 3 et à amener les deux bandes profilées en regard l'une de l'autre en plaçant la bande destinée à former le parement extérieur 2 au-dessous de la bande destinée à former le parement intérieur 3.In the case of a manufacturing process in continuous with a thermal insulation foam core 4 polyurethane, the process consists in profiling a first metal strip intended to form the facing outside 2, to profile a second metal strip intended to form the interior facing 3 and to bring the two profiled strips facing each other in placing the strip intended to form the exterior facing 2 below the strip intended to form the facing interior 3.

Ensuite, on injecte entre les bandes une composition à polymériser et à mousser et destinée à former l'âme 4, on introduit entre les bandes enserrant ladite composition dans un conformateur et on fait polymériser et mousser ladite composition pour former l'âme 4.Then, we inject a composition to be polymerized and foamed and intended for form the core 4, we introduce between the bands enclosing said composition in a shaper and we make polymerizing and foaming said composition to form soul 4.

A la sortie de ce conformateur, l'âme 4 est refroidie et le composite ainsi obtenu est découpé en panneaux aux dimensions requises.At the exit of this conformator, the core 4 is cooled and the composite thus obtained is cut into panels with the required dimensions.

Après avoir amené les deux bandes profilées en regard l'une de l'autre, on peut placer une ou plusieurs plaques d'isolation acoustique 10 dans le logement 7 correspondant et disposer une ou plusieurs lamelles 21 sur chaque plaque 10 d'isolation acoustique par emboítement dans le logement 7 correspondant.After bringing the two profiled strips facing each other, we can place one or more soundproofing plates 10 in the housing 7 corresponding and have one or more lamellae 21 on each plate 10 of sound insulation by interlocking in the corresponding housing 7.

Cette disposition est particulièrement avantageuse pour un procédé de fabrication en continu, car les lamelles 21 sont profilées en continu à partir d'une bande métallique.This provision is particularly advantageous for a continuous manufacturing process, because the slats 21 are continuously profiled from with a metal strip.

Dans le cas où la plaque 10 d'isolation acoustique comporte une peau de recouvrement de type kraft-aluminium directement collée sur sa surface externe, la plaque 10 est placée par emboítement dans le logement 7 correspondant.In the case where the insulation plate 10 acoustic has a type of covering skin kraft-aluminum directly bonded to its surface external, the plate 10 is placed by nesting in the corresponding housing 7.

Pour un procédé de fabrication discontinu, le procédé consiste à découper une bande métallique en parements, à profiler les parements extérieurs 2 et intérieurs 3 et à placer dans une presse un parement extérieur 2 au-dessous d'un parement intérieur 3.For a discontinuous manufacturing process, the method involves cutting a metal strip into siding, profiling the exterior siding 2 and interior 3 and place a facing in a press exterior 2 below interior facing 3.

Ensuite, on injecte entre les parements 2 et 3 une composition à polymériser et à mousser et destinée à former l'âme 4, on fait polymériser et mousser ladite composition pour former l'âme 4 et le composite ainsi obtenu est sorti de la presse et on laisse l'âme 4 se refroidir.Then, we inject between the facings 2 and 3 a composition to polymerize and foam and intended to form the core 4, said polymer is made and foamed composition to form the core 4 and the composite as well got out of the press and let soul 4 get cool.

Une ou plusieurs plaques 10 d'isolation acoustique sont placées dans le logement 7 correspondant éventuellement avec une plusieurs lamelles 21 de recouvrement et ces opérations sont renouvelées pour chaque panneau d'isolation thermo-acoustique.One or more insulating plates 10 acoustics are placed in the corresponding housing 7 possibly with a plurality of covers 21 and these operations are repeated for each thermo-acoustic insulation panel.

Le fait de placer le parement extérieur 2 en bas au cours du procédé de fabrication du panneau thermo-acoustique permet, dans le cas de parements extérieurs 3 à nervures profondes, d'introduire la composition à polymériser et à mousser et destinée à former l'âme 4 dans les nervures et d'obtenir ainsi de la mousse jusqu'au fond de ces nervures et par conséquent de pouvoir réaliser la cohésion entre le parement extérieur 2, l'âme 4 et le parement intérieur 4 favorisant ainsi l'homogénéité et la rigidité du produit.Placing the exterior facing 2 in low during the panel manufacturing process thermo-acoustic allows, in the case of facing outer 3 with deep ribs, to introduce the composition to be polymerized and foamed and intended for form the soul 4 in the ribs and thus obtain the foam to the bottom of these ribs and therefore to be able to achieve cohesion between the facing exterior 2, core 4 and interior facing 4 favoring thus the homogeneity and the rigidity of the product.
