Description

La présente invention est relative à un primitif pour panneau destiné à assurer l'isolation thermo-acoustique, notamment sous étanchéité et/ou sous finition, de parois constituées d'éléments porteurs ou éléments support en tôles d'acier nervurés, en bois ou béton.The present invention relates to a primitive for a panel intended to ensure the thermo-acoustic insulation, in particular under seal and / or under finish, of walls constituted by supporting elements or support elements made of ribbed steel sheets, of wood or concrete .

Ces panneaux sont essentiellement constitués à partir d'un primitif formé à partir d'un matelas de laine minérale, de roche ou de verre, de forte densité (masse volumique comprise entre 50 à 400 kg/m3), selon des plages d'épaisseur comprises entre 20 à 300 mm et d'un parement disposé sur une face principale dudit primitif. Ces panneaux sont généralement positionnés et solidarisés par collage, par fixation mécanique à des éléments de support ou des parois horizontales ou verticales, inclinées, voire courbes, qui sont plus particulièrement destinées à des bâtiments à caractère industriel ou résidentiel, dans une application relevant des travaux neufs ou de rénovation.These panels consist essentially of a primitive formed from a mat of mineral wool, rock or glass, of high density (density between 50 to 400 kg / m 3 ), according to ranges of thickness between 20 to 300 mm and a facing disposed on a main face of said primitive. These panels are generally positioned and secured by gluing, by mechanical attachment to support members or horizontal or vertical walls, inclined or curved, which are more particularly intended for industrial or residential buildings, in an application of the work new or renovation.

Sensiblement de forme parallélépipédique, ces panneaux présentent deux faces principales et quatre bords longitudinaux respectivement parallèles deux à deux, généralement perpendiculaires à ces faces principales ; ces panneaux sont destinés à être juxtaposés à des panneaux similaires, selon leurs bords longitudinaux de manière à composer un système d'isolation d'un édifice industriel, résidentiel, tertiaire ou agricole.These parallelepipedally shaped panels have two main faces and four longitudinal edges respectively parallel two by two, generally perpendicular to these main faces; these panels are intended to be juxtaposed to similar panels along their longitudinal edges so as to compose an insulation system of an industrial building, residential, tertiary or agricultural.

On connaît une première famille de panneaux constitués à partir d'un primitif formé à partir d'un matelas de laine minérale et d'un parement disposé sur l'une des faces principales dudit primitif. Le principal inconvénient de ce type panneau réside dans le fait qu'il offre une résistance réduite à l'arrachement, en particulier, le parement, consécutivement à une rafale de vent, peut avoir tendance à se désolidariser du primitif.A first family of panels made from a primitive formed from a mineral wool mat and a facing disposed on one of the main faces of said primitive is known. The main disadvantage of this type of panel lies in the fact that it offers a reduced resistance to tearing, in particular, the facing, following a gust of wind, may have a tendency to separate from the primitive.

Pour résoudre ce problème de résistance à l'arrachement, on a été amené à concevoir une deuxième famille de panneaux qui se distingue de la précédente par le fait que le parement se trouve rabattu ou rebordé sur l'autre face principale du panneau (cette autre face principale est celle qui se situe à l'opposé de celle qui est revêtue par le parement) ; de cette façon les rabats n'offrent pas de prise au vent, et la résistance à l'arrachement s'en trouve nettement améliorée.To solve this problem of resistance to tearing, it was necessary to design a second family of panels that differs from the previous in that the facing is folded or flanged on the other main face of the panel (this other the main face is the one opposite to that facing the facing); in this way the flaps do not offer wind resistance, and the resistance to tearing is significantly improved.

Ce type de panneaux est décrit par exemple dans le brevet européen EP 0 109 879 ou dans le brevet français FR 2 679 279.This type of panel is described for example in the European patent EP 0 109 879 or in the French patent FR 2 679 279.

Or, afin d'anticiper les exigences des dispositions réglementaires, à la fois tant au niveau de leur résistance mécanique que de leurs propriétés d'isolation acoustique et/ou thermique, ainsi que leur performance vis à vis du feu, des matériaux encore plus performants sont souhaitablesHowever, in order to anticipate the requirements of the regulatory provisions, both in terms of their mechanical strength as well as their acoustic and / or thermal insulation properties, as well as their performance with respect to fire, even more efficient materials are desirable

En effet, parmi les normes les plus sévères et les plus contraignantes, on relève les dispositions réglementaires en matière de sécurité vis à vis du risque incendie, que ce soit un feu issu de l'intérieur ou de l'extérieur. Un feu est dit « un feu issu de l'intérieur » lorsque les flammes proviennent ou se propagent à l'intérieur d'une enceinte, et au contraire, un feu est dit « un feu issu de l'extérieur » lorsque au contraire les flammes sont situées à l'extérieur de l'enceinte.Indeed, among the most stringent and most stringent standards, we note the regulatory provisions for fire safety, whether a fire from inside or outside. A fire is said to be "a fire from within" when the flames originate or spread inside an enclosure, and on the contrary, a fire is called "fire from outside" when, on the contrary, flames are located outside the enclosure.

Or, pour des panneaux revêtus d'un parement bitumineux, le respect de ces conditions normatives, tout particulièrement en matière de résistance au feu, est problématique, le parement bitumineux, surtout lorsqu'il se trouve rabattu ou rebordé sur la face du panneau qui est dirigée vers l'intérieur, est susceptible de constituer un vecteur pour la propagation de la flamme.However, for panels coated with an asphalt facing, the respect of these normative conditions, especially in terms of fire resistance, is problematic, the asphalt facing, especially when it is folded or flanged on the face of the panel which is directed inward, is likely to constitute a vector for the propagation of the flame.

L'objet de la présente invention est de proposer un primitif permettant de fabriquer un panneau isolant pouvant jouer le rôle de barrière incendie, ce panneau étant recouvert d'un parement, ledit parement étant susceptible en outre de résister à un effort d'arrachement (notamment celui du vent).The object of the present invention is to propose a primitive making it possible to manufacture an insulating panel that can act as a fire barrier, this panel being covered with a facing, said facing being moreover able to withstand a tearing force ( especially that of the wind).

Dans la présente invention, on définit par parement tout revêtement se présentant sous forme d'une feuille mince dont l'épaisseur est inférieure à 5 mm, et notamment voisine de 1 mm, et disposant d'une aptitude au pliage, au bombage, à une déformation lui permettant d'épouser l'une des faces du panneau.In the present invention, by facing is defined any coating in the form of a thin sheet whose thickness is less than 5 mm, and in particular close to 1 mm, and having an ability to bend, bend, a deformation allowing him to marry one of the faces of the panel.

Le panneau sensiblement de forme parallélépipédique selon l'invention comprend un primitif selon la revendication 1.The substantially parallelepiped-shaped panel according to the invention comprises a primitive according to claim 1.

La zone en relief, qui dans la présente invention peut être constituée par une zone en creux ou une zone en bosse, est suffisamment importante en section et en profondeur pour permettre au rabat de s'encastrer au sein de la zone en relief de manière à ce qu'il n'existe pas de sur-épaisseur de matière sur le bord longitudinal dudit panneau.The area in relief, which in the present invention can be constituted by a hollow zone or a hump zone, is sufficiently large in section and depth to allow the flap to fit within the raised area so that there is no over-thickness of material on the longitudinal edge of said panel.

Pour une meilleure définition de l'invention, on définira également les termes suivants :

  • Extérieur : est utilisé lorsque le panneau est solidaire d'un élément formant support d'une enceinte, l'une de ses faces principales (celle qui est revêtue du parement) est alors dirigée vers l'extérieur de l'enceinte.
  • Intérieur: est utilisé lorsque le panneau est solidaire d'un élément formant support d'une enceinte, l'une de ses faces principales (celle qui est en contact avec le support) est alors dirigée vers l'intérieur de l'enceinte.
For a better definition of the invention, the following terms will also be defined:
  • Exterior: is used when the panel is secured to a support member of an enclosure, one of its main faces (that which is coated facing) is then directed outwardly of the enclosure.
  • Inside: is used when the panel is secured to a support member of an enclosure, one of its main faces (the one that is in contact with the support) is then directed towards the inside of the enclosure.

Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • la zone en relief est réalisée sur une fraction de l'épaisseur du matelas, au droit d'une face principale dudit matelas, cette zone en relief délimitant deux zones contiguës,
  • le matelas est pourvu d'au moins deux zones en relief, chacune de ces zones étant positionnée sur un bord longitudinal dudit matelas,
  • le bord longitudinal comportant la zone en relief est incliné par rapport à la face principale du matelas devant être revêtue du parement, selon un angle supérieur à 90 °,
  • la zone en relief est réalisée sous la forme d'un évidement de matière,
  • la zone en relief est réalisée sous la forme d'une excroissance de matière.
In preferred embodiments of the invention, one or more of the following may also be used:
  • the zone in relief is made on a fraction of the thickness of the mattress, to the right of a main face of said mattress, this zone in relief delimiting two contiguous zones,
  • the mattress is provided with at least two zones in relief, each of these zones being positioned on a longitudinal edge of said mattress,
  • the longitudinal edge comprising the raised area is inclined relative to the main face of the mattress to be coated facing, at an angle greater than 90 °,
  • the area in relief is made in the form of a recess of material,
  • the area in relief is made in the form of an outgrowth of material.

Selon un autre aspect de l'invention, celle-ci vise un panneau constitué essentiellement d'un primitif tel que précédemment décrit et d'un parement,According to another aspect of the invention, it relates to a panel consisting essentially of a primitive as described above and a facing,

Avantageusement, le parement du panneau comporte au moins un rabat, ledit rabat étant reçu dans au moins une zone en relief réalisé au niveau d'un bord longitudinal dudit panneau, ledit rabat étant destiné à coopérer au niveau de ladite zone en relief à l'aide d'un moyen d'adhésion, notamment du bitume.Advantageously, the facing of the panel comprises at least one flap, said flap being received in at least one raised area made at a longitudinal edge of said panel, said flap being intended to cooperate at said raised area at the using a means of adhesion, including bitumen.

Selon une autre mode préféré de réalisation, le panneau comporte deux zones en relief, chacune de ces zones en relief recevant un rabat dudit parement.According to another preferred embodiment, the panel comprises two raised areas, each of these raised areas receiving a flap of said facing.

Selon encore une caractéristique avantageuse, le parement est essentiellement constitué par un voile de verre enduit de bitume, ledit parement étant éventuellement renforcé, par une grille de verre.According to another advantageous characteristic, the facing is essentially constituted by a veil of glass coated with bitumen, said facing being optionally reinforced by a glass grid.

Selon une autre variante préférée, le parement est essentiellement constitué par un kraft.According to another preferred variant, the facing is essentially constituted by a kraft.

Selon encore d'autres caractéristiques avantageuses, le kraft comporte au moins une face traitée déperlante et présente d'une part, un aspect lisse et d'autre part, une meilleure répartition des contraintes mécaniques.According to still other advantageous characteristics, the kraft comprises at least one water-repellent treated surface and presents, on the one hand, a smooth appearance and, on the other hand, a better distribution of the mechanical stresses.

Selon encore une variante préférée, le parement est support de réactif pour collage.According to another preferred variant, the facing is a reagent support for bonding.

Ce support de réactif est un agent chimique (par exemple un primaire d'accrochage notamment) qui permet d'améliorer l'adhésion avec un revêtement qui sera rapporté ultérieurement sur le parement.This reagent support is a chemical agent (for example a primer in particular) which improves the adhesion with a coating that will be reported later on the facing.

La présente invention vise également une toiture constituée d'éléments porteurs en tôles d'acier nervurés, en bois ou béton, sur laquelle est fixée une pluralité de panneaux tels que précédemment décrits.The present invention also relates to a roof consisting of load-bearing elements of ribbed steel sheets, wood or concrete, on which is fixed a plurality of panels as previously described.

Elle vise également et de manière plus générale toute paroi d'édifice industriel, résidentiel, tertiaire ou agricole formant support sur laquelle est fixée une pluralité de panneaux conformes aux dispositions précédentes.It also aims and more generally any wall of industrial building, residential, tertiary or agricultural forming support on which is fixed a plurality of panels in accordance with the preceding provisions.

Ce panneau, au niveau de son parement, voit sa résistance à l'arrachement améliorée, par contre il dispose encore d'une moindre résistance au risque incendie.The known panel shown in FIG. 2 differs from that of FIG. 1 in that side flaps coming from the facing are secured to the other main face of the panel (this other main face being that opposite to that on which is fixed the facing 3, this other main face also corresponding to the face which is intended to be in contact with a support member). This panel, at the level of its facing, sees its resistance to tearing improved, against it still has a lower resistance to fire risk.

Le panneau 1 représenté en figure 3 est formé d'un primitif constitué essentiellement d'un matelas 2 de laine de roche dont le taux de liant est de l'ordre de 3 à 4 % en poids, ce taux étant l'une des caractéristiques structurelles du primitif. Il présente une masse volumique de l'ordre de 140 kg/m3 et une épaisseur de 80 mm. Bien entendu, les caractéristiques dimensionnelles et structurelles du matelas 2 sont données à titre purement indicatif, et celles-ci peuvent varier en fonction des applications recherchées. Ainsi l'invention peut s'appliquer à des panneaux dont la gamme de masse volumique est comprise entre 50 à 400 kg/m3 et notamment de 70 à 200 kg/m3, et préférentiellement voisine de 140 kg/m3, pour des épaisseurs pouvant varier de 30 à 300 mm.The panel 1 represented in FIG. 3 is formed of a primitive consisting essentially of a rock wool mattress 2 whose binder content is of the order of 3 to 4% by weight, this rate being one of the characteristics structural aspects of the primitive. It has a density of the order of 140 kg / m 3 and a thickness of 80 mm. Of course, the dimensional and structural characteristics of the mattress 2 are given for information only, and these may vary depending on the desired applications. Thus the invention can be applied to panels whose density range is between 50 to 400 kg / m 3 and in particular 70 to 200 kg / m 3 , and preferably close to 140 kg / m 3 , for thicknesses ranging from 30 to 300 mm.

L'une des faces principales du primitif du matelas 1 est destinée à recevoir par collage ou tout autre moyen permettant d'assurer l'adhésion entre deux matériaux, un parement 3. Ce parement 3 peut être constitué de plusieurs éléments tel que par exemple un voile de verre, bituminé ou non, ou une feuille de kraft ou tout autre type de matériau, ces éléments sont éventuellement associés avec une grille de verre pour renforcer le parement.One of the main faces of the primitive of the mattress 1 is intended to receive by gluing or any other means for ensuring adhesion between two materials, a facing 3. This facing 3 may consist of several elements such as for example a glass veil, bituminous or not, or a sheet of kraft or any other type of material, these elements are optionally associated with a glass grid to reinforce the siding.

On entend par voile de verre tout support réalisé à partir d'un non tissé en verre.Glass mat is any support made from a non-woven glass.

L'application du parement s'effectue directement après l'imprégnation du voile par du bitume ou par un autre moyen de collage, afin que le moyen devant assurer l'adhésion puisse pénétrer l'une des faces principales du matelas 2, du moins sur une faible épaisseur de ce dernier.The facing is applied directly after the impregnation of the veil by bitumen or other means of bonding, so that the means to ensure adhesion can penetrate one of the main faces of the mattress 2, at least on a small thickness of the latter.

Afin d'améliorer l'ancrage du parement 3 sur la face supérieure du matelas 2, on peut réaliser en surface de cette dernière une pluralité d'évidements obtenus par poinçonnage, comme ceux décrits par exemple dans le brevet FR 2 679 279.In order to improve the anchoring of the facing 3 on the upper face of the mattress 2, it is possible to realize on the surface of the latter a plurality of recesses obtained by punching, such as those described for example in patent FR 2 679 279.

En variante, le parement 3 n'est pas un voile de verre, éventuellement renforcé, et enduit d'un matériau bitumineux mais un parement en kraft.Alternatively, the facing 3 is not a glass veil, possibly reinforced, and coated with a bituminous material but a kraft facing.

Dans ce cas, ce parement 3 constitué de kraft peut faire office de parement de finition.In this case, this facing 3 consisting of kraft can be used as finish facing.

Selon un exemple de parement kraft pouvant être utilisé en tant que parement de finition, il peut s'agir d'un kraft dont l'une des faces est traitée déperlante (qui supporte le mouillage par un fluide de refroidissement (eau)). De plus, cette face ainsi traitée présente d'une part, une surface lisse, ce qui minimisera les quantités de colle utilisées ultérieurement, et d'autre part une meilleure répartition des contraintes mécaniques. Le kraft fabriqué par la société canadienne Cascades Sainte Marie (ARJISO 200™) est un exemple de réalisation possédant ces propriétés.According to an example of kraft facing that can be used as a finishing facing, it may be a kraft whose one side is treated water-repellent (which supports wetting with a cooling fluid (water)). In addition, this face thus treated has on the one hand a smooth surface, which will minimize the amounts of glue used later, and on the other hand a better distribution of mechanical stresses. The kraft manufactured by the Canadian company Cascades Sainte Marie (ARJISO 200 ™ ) is an example of an embodiment possessing these properties.

Ce panneau 1 isolant peut être utilisé pour des systèmes d'isolation de toitures 4 horizontales, verticales ou inclinées, voire courbes, en juxtaposant au niveau de leurs bords longitudinaux une pluralité de panneaux, les panneaux étant solidarisés et fixés mécaniquement à la toiture à ossature métallique, horizontale, formée de profilés métalliques par l'intermédiaire de vis ou rondelles. En variante, les panneaux pourraient être collés aux supports.This insulating panel 1 can be used for roof insulation systems 4 horizontal, vertical or inclined, or curved, by juxtaposing the at their longitudinal edges a plurality of panels, the panels being secured and mechanically fastened to the roof with a metal frame, horizontal, formed of metal sections by means of screws or washers. Alternatively, the panels could be glued to the supports.

Bien entendu, le parement 3 est orienté vers l'extérieur de l'enceinte ainsi recouverte, par opposition à la face du panneau qui est dépourvue de parement qui est dirigée vers l'intérieur de l'enceinte et qui est au contact de l'ossature de la toiture 4 ou de toute autre paroi liée au support de l'édifice industriel, résidentiel, tertiaire, ou agricole.Of course, the facing 3 is oriented towards the outside of the enclosure thus covered, as opposed to the face of the panel which is devoid of facing which is directed towards the interior of the enclosure and which is in contact with the framework of the roof 4 or any other wall connected to the support of the industrial building, residential, tertiary, or agricultural.

Sur la figure 3, on remarque que le parement 3 n'est pas rebordé sur la face principale du panneau qui est destinée à être dirigée vers l'intérieur de l'enceinte et plus particulièrement qu'au moins un rabat 5 du parement 3 n'est fixé que sur une fraction de l'épaisseur d'un des bords longitudinaux du panneau (on dit alors que le panneau est semi-rebordé). Ce panneau 1 est semi-rebordé sur deux de ses quatre bords, plus particulièrement au niveau de deux bords longitudinaux sensiblement parallèlesIn FIG. 3, it will be noted that the facing 3 is not flanged on the main face of the panel which is intended to be directed towards the inside of the enclosure and more particularly that at least one flap 5 of the facing 3 n It is fixed only on a fraction of the thickness of one of the longitudinal edges of the panel (it is said that the panel is semi-flanged). This panel 1 is semi-flanged on two of its four edges, more particularly at two substantially parallel longitudinal edges.

On entend par « semi rebordé », le fait que la face principale du panneau (face intérieure) qui est destinée à être dirigée vers le support n'est recouverte ni en totalité, ni en partie par un rabat issu du parement, dans cette configuration le(s) rabat(s) 5 issu(s) de la face du parement 3 dirigée vers l'extérieur de l'enceinte est(sont) semi-rebordé(s) de manière à ce que les fibres du panneau soient directement au contact de l'ossature du toit recouvrant l'enceinte.The term "semi-flange" means that the main face of the panel (inside face) which is intended to be directed towards the support is not covered in whole or in part by a flap from the facing, in this configuration the flap (s) 5 (s) coming from the face of the facing 3 directed towards the outside of the enclosure is (are) semi-flanged (s) so that the fibers of the panel are directly at the contact of the roof frame covering the enclosure.

Sur les figures 4 et suivantes, on a représenté différents modes de réalisation d'un panneau selon l'invention.FIGS. 4 and following show different embodiments of a panel according to the invention.

Ainsi, sur la figure 4 en particulier, on a représenté une toiture constituée par la juxtaposition d'une pluralité de panneaux 1. Chacun des rabats 5 du parement 3 est fixé (par collage ou par un autre procédé équivalent permettant d'assurer l'adhésion entre deux surfaces) au sein d'une zone en relief 6 pratiquée dans l'épaisseur du panneau.Thus, in FIG. 4 in particular, a roof consisting of the juxtaposition of a plurality of panels 1 is shown. Each of the flaps 5 of the facing 3 is fixed (by gluing or by another equivalent method making it possible to ensure adhesion between two surfaces) within a relief zone 6 made in the thickness of the panel.

Cette zone en relief 6 (en creux ou en saillie) délimite deux zones contiguës 7, 8 dont l'une d'entre elle forme une excroissance de matière 9 (visible en figures 6 et 7). Dans cet exemple de la figure 4, l'excroissance de matière 9 est positionnée au droit de la face principale du panneau 1 qui est destinée à être dirigée vers l'intérieur de l'enceinte, la partie contiguë 8 étant dans cet exemple (la partie en relief est en creux) au droit de l'autre face principale du panneau 1, celle qui est destinée à être dirigée vers l'extérieur de l'enceinte.This raised zone 6 (recessed or protruding) delimits two contiguous zones 7, 8, one of which forms an outgrowth of material 9 (visible in FIGS. 6 and 7). In this example of FIG. 4, the protrusion of material 9 is positioned to the right of the main face of the panel 1 which is intended to be directed towards the inside of the enclosure, the contiguous part 8 being in this example (FIG. raised portion is recessed) to the right of the other main face of the panel 1, that which is intended to be directed towards the outside of the enclosure.

Ainsi, en juxtaposant au moins deux panneaux 1 selon le mode de réalisation précédemment décrit, les parties en relief 6 respectives coopèrent de manière à conformer au niveau des faces principales des panneaux destinés à être au contact du support, une couche uniforme formant barrière, cette barrière pouvant être acoustique et/ou thermique et/ou vis-à-vis du feu.Thus, by juxtaposing at least two panels 1 according to the embodiment previously described, the respective raised parts 6 cooperate to form at the level of the main faces of the panels intended to be in contact with the support, a uniform barrier layer, this barrier that can be acoustic and / or thermal and / or fireproof.

On peut noter qu'en procédant à un chauffage superficiel du parement bitumeux, tout particulièrement au niveau des zones semi rebordées, ces zones de bitume vont fusionner localement et après refroidissement, réaliser une barrière d'étanchéité.It may be noted that by performing a surface heating of the bituminous coating, particularly in the semi-flanged areas, these bitumen areas will fuse locally and after cooling, provide a sealing barrier.

Sur la figure 5, on a représenté un panneau 1 semi-rebordé que sur l'un des quatre côtés du panneau.In Figure 5, there is shown a panel 1 semi-flanged on one of the four sides of the panel.

Sur la figure 6, l'un au moins des bords comportant la zone en relief 6 est incliné par rapport à l'une des faces principales du panneau 1. En l'occurrence dans cet exemple de réalisation, le bord semi-rebordé est incliné d'un angle α supérieur à 90° par rapport à la face du panneau qui est destinée à être dirigée vers l'extérieur de l'enceinte.In FIG. 6, at least one of the edges comprising the raised zone 6 is inclined with respect to one of the main faces of the panel 1. In this example, in this embodiment, the semi-flanged edge is inclined. an angle α greater than 90 ° with respect to the face of the panel which is intended to be directed towards the outside of the enclosure.

La figure 7 illustre un autre mode de réalisation d'un panneau. Sur l'un des bords du panneau, la zone en relief 6 destinée à coopérer avec le rabat 5 venu du parement 3 est en saillie tandis que la zone en relief 6 située au niveau du bord opposé est en creux.Figure 7 illustrates another embodiment of a panel. On one of the edges of the panel, the raised area 6 intended to cooperate with the flap 5 from the facing 3 is projecting while the raised area 6 located at the opposite edge is recessed.

En juxtaposant au moins deux panneaux 1 selon ce mode de réalisation selon leurs bords longitudinaux respectifs en associant d'une part une zone en saillie 6 d'un premier panneau 1 avec une zone en creux 6' venue d'un second panneau 1', on réalise un système isolant dont la face dirigée vers l'intérieur de l'enceinte forme une barrière acoustique et/ou thermique. Les rabats 5,5' du parement 3,3' se trouvent « protégés » soit par une zone en saillie, soit par une zone en creux.By juxtaposing at least two panels 1 according to this embodiment according to their respective longitudinal edges by associating on the one hand a protruding zone 6 of a first panel 1 with a hollow zone 6 'coming from a second panel 1', an insulating system is produced whose face directed towards the interior of the enclosure forms an acoustic and / or thermal barrier. The flaps 5, 5 'of the cladding 3, 3' are "protected" either by a protruding zone or by a hollow zone.

Quel que soit le mode de réalisation, la présence des rabats au niveau des bords longitudinaux des panneaux augmente considérablement à la fois la résistance à l'arrachement (cet arrachement pouvant être consécutif à une rafale de vent) et la résistance vis-à-vis du risque incendie des panneaux selon l'invention par rapport à ceux de l'art antérieur.Whatever the embodiment, the presence of the flaps at the longitudinal edges of the panels considerably increases both the tear resistance (this tearing may be consecutive to a gust of wind) and the resistance vis-à-vis fire risk of the panels according to the invention compared to those of the prior art.

L'invention concerne également un procédé et un dispositif pour la fabrication en continu des panneaux décrits précédemment.The invention also relates to a method and a device for continuously manufacturing the panels described above.

Selon le procédé, on fabrique en continu un matelas d'isolation rigide en fibres minérales, de forte densité, par les procédés classiques pour la laine de roche ou la laine de verre, on crée si besoin des évidements par poinçonnage de la surface destinée à recevoir le parement, afin de former des points d'ancrage régulièrement répartis sur la surface pour la colle (ou autre) utilisée pour la fixation du parement sur l'une des faces du panneau.According to the method, a rigid high-density mineral fiber insulation mat is continuously manufactured by conventional methods for rockwool or glass wool, puncturing recesses of the surface for receive the facing, to form anchoring points evenly distributed on the surface for the glue (or other) used for fixing the facing on one side of the panel.

Le matelas de fibres minérales préalablement enduites de liant est acheminé par des tapis de convoyage au sein d'une enceinte de traitement thermique (étuve) dans laquelle le liant polymérise et consolide le matelas en lui donnant, grâce à des rouleaux presseurs, ses caractéristiques dimensionnelles et conformant ainsi un primitif.The mat of mineral fibers previously coated with binder is conveyed by conveyor belts in a heat treatment chamber (oven) in which the binder polymerizes and consolidates the mattress by giving it, thanks to pressure rollers, its dimensional characteristics. and thus conforming a primitive.

En aval de cette enceinte, on procède à la réalisation des zones en relief (en creux, ou en saillie) sur l'un au moins des bords longitudinaux du matelas.Downstream of this chamber, it proceeds to the realization of the raised areas (hollow, or protruding) on at least one of the longitudinal edges of the mattress.

L'enlèvement de matière sur une fraction de l'épaisseur du matelas est réalisé par un organe de coupe (scie, fraise) ou par tout autre moyen équivalent, comme par exemple à l'aide d'un fluide sous pression (jet d'eau par exemple).The removal of material over a fraction of the thickness of the mattress is performed by a cutting member (saw, milling cutter) or by any other equivalent means, such as for example using a fluid under pressure (jet of water for example).

L'organe de coupe est intégré dans le procédé de fabrication des panneaux. Il est situé en aval de l'étuve et en amont de l'unité de découpe finale. En variante, on peut néanmoins prévoir de réaliser cette opération au sein d'une opération de reprise, soit par exemple après découpe dans le sens de défilement du matelas, et/ou soit par exemple après découpe dans le sens transversal (par rapport au sens de défilement) du matelas.The cutter is integrated in the manufacturing process of the panels. It is located downstream of the oven and upstream of the final cutting unit. As a variant, it is nevertheless possible to provide this operation within a recovery operation, for example after cutting in the direction of travel of the mattress, and / or, for example, after cutting in the transverse direction (with respect to the direction scroll) of the mattress.

On applique ensuite la colle ou similaire et le parement sur la face pourvue éventuellement des évidements.The glue or the like and the facing are then applied to the face optionally provided with the recesses.

Dans une forme préférée, la colle est apportée sur le matelas simultanément au parement. C'est le cas notamment lorsque le parement utilise du bitume en tant que colle et qu'il en est imprégné avant son application sur le matelas.In a preferred form, the glue is provided on the mattress simultaneously to the facing. This is particularly the case when the facing uses bitumen as glue and is impregnated before its application on the mattress.

On peut remarquer que lorsque le parement est un kraft dont l'une des faces est traitée déperlante, le refroidissement nécessaire à la solidification du bitume situé à l'interface entre le primitif et le parement est amélioré.It may be noted that when the facing is a kraft whose one face is treated water-repellent, the cooling necessary for the solidification of the bitumen located at the interface between the primitive and the facing is improved.

En effet, ce refroidissement est généralement effectué par voie humide, le fluide de refroidissement qui est au contact de face déperlante du parement permet de refroidir le bitume sans détériorer ce dernier.Indeed, this cooling is generally carried out wet, the cooling fluid which is in contact with water-repellent face of the facing makes it possible to cool the bitumen without damaging the latter.

Or, avec des parements traditionnels (sans traitement hydrophobe), en raison de refroidissement par voie humide, il y a un risque de détérioration de ce dernier (gonflement, défaut de surface...).However, with traditional facings (without hydrophobic treatment), due to wet cooling, there is a risk of deterioration of the latter (swelling, surface defect ...).

Le parement que l'on applique en continu présente une largeur correspondant à la largeur du matelas augmentée d'au moins un rabat, dont la dimension correspond à la profondeur du trait de coupe opéré préalablement, ce qui permet un recouvrement que sur au moins une fraction de l'épaisseur du matelas.The facing which is applied continuously has a width corresponding to the width of the mattress increased by at least one flap, the size of which corresponds to the depth of the cut line previously made, which allows a covering that on at least one fraction of the thickness of the mattress.

Le parement peut comprendre une feuille de matière plastique dite de séparation comme dans le cas du panneau décrit dans l'EP-A-0 109 879 déjà cité.The facing may comprise a so-called separation sheet of plastic as in the case of the panel described in EP-A-0 109 879 already cited.

Le parement peut assurer lui-même cette fonction de séparation si ce dernier est réalisé en kraft ou en autre matériau.The siding can ensure itself this separation function if the latter is made of kraft or other material.

L'invention concerne également un dispositif pour la mise en oeuvre du procédé et la fabrication du panneau isolant.The invention also relates to a device for implementing the method and the manufacture of the insulating panel.

Le dispositif comprend les moyens de fabrication connus pour la réalisation du panneau isolant, c'est-à-dire un dispositif de fibrage avec incorporation du liant au moment du fibrage, un convoyeur recevant les fibres, des moyens amenant le matelas à l'épaisseur désirée et une étuve pour la polymérisation du liant, des moyens pour l'apport du parement et son adhésion sur la face inférieure du panneau, des moyens de découpe. Ces moyens de découpe consistent en des premiers moyens de découpe pour la mise aux dimensions dans le sens transversal (par rapport au sens de défilement du matelas), des seconds moyens pour la mise aux dimensions dans le sens longitudinal (parallèle au sens de défilement du matelas), et enfin des troisièmes moyens pour la réalisation des zones en reliefs dans une fraction de l'épaisseur du matelas.The device comprises the known manufacturing means for producing the insulating panel, that is to say a fiberizing device incorporating the binder at the time of drawing, a conveyor receiving the fibers, means bringing the mattress to the thickness desired and an oven for the polymerization of the binder, means for the contribution of the facing and its adhesion on the underside of the panel, cutting means. These cutting means consist of first cutting means for dimensioning in the transverse direction (with respect to the running direction of the mattress), second means for dimensioning in the longitudinal direction (parallel to the direction of travel of the mattress), and finally third means for producing relief areas in a fraction of the thickness of the mattress.

Il comprend en outre un système disposé entre le poste de découpe des zones en relief au sein d'une fraction de l'épaisseur du matelas et le poste de collage du parement, qui comprend un organe presseur permettant d'appliquer une pression constante sur au moins un rabat du parement que l'on veut faire adhérer au niveau de la zone en relief préalablement enlevée.It further comprises a system disposed between the cutting station of the raised areas within a fraction of the thickness of the mattress and the siding bonding station, which comprises a pressing member for applying a constant pressure on to minus a flap of the facing that one wants to adhere to the level of the raised area previously removed.
