Description
La présente invention concerne un complexe d'isolation multicouche, sonThe present invention relates to a multilayer insulation complex, its
procédé de fabrication et un dispositif de mise en oeuvre de ce procédé. manufacturing method and a device for implementing this method.
Pour réaliser l'isolation d'un bâtiment et, notamment, de la face intérieure d'une toiture, on a longtemps fait appel à de la laine de verre. La laine de verre est une matière fibreuse qui peut emprisonner une grande quantité d'air; à ce titre la laine de verre présente une faible conductivité thermique et constitue une bonne matière isolante. To achieve the insulation of a building and, in particular, the inner face of a roof, it has long been using glass wool. Glass wool is a fibrous material that can trap a large amount of air; as such glass wool has a low thermal conductivity and is a good insulating material.
Toutefois, la laine de verre est sensible à l'humidité. En cas de 10 mouillage par infiltration ou par condensation, la laine de verre peut se tasser et perdre tout ou partie de ses propriétés isolantes. However, glass wool is sensitive to moisture. In the case of wetting by infiltration or condensation, the glass wool may become compact and lose all or part of its insulating properties.
De plus, la laine de verre du fait de sa nature fibreuse peut avoir tendance à largueur des fibres qui peuvent être néfastes pour l'appareil respiratoire ou pour l'épiderme d'individus séjournant dans un bâtiment isolé avec un tel matériau. In addition, glass wool because of its fibrous nature may tend to largor fibers that may be harmful to the respiratory system or the epidermis of individuals staying in a building insulated with such material.
Il existe, par ailleurs, des complexes d'isolation multicouche comprenant deux films plastiques métallisés enfermant une ou plusieurs couches de matériau isolant de type ouate minérale, synthétique ou végétale. There are, moreover, multilayer insulation complexes comprising two metallized plastic films enclosing one or more layers of insulating material of mineral, synthetic or vegetable wadding type.
Ce type de complexes se présente généralement sous la forme d'une bande de une ou plusieurs dizaines de mètres de long dont les bords longitudinaux sont soudés de manière continue. This type of complex is generally in the form of a band of one or more tens of meters long whose longitudinal edges are welded continuously.
Ces complexes d'isolation agissent principalement par réflexion car la chaleur se réfléchit sur les couches externes constituées de films plastiques métallisés. Leur pouvoir isolant est sensiblement indépendant de leur épaisseur. These insulation complexes act mainly by reflection because the heat is reflected on the outer layers made of metallized plastic films. Their insulating power is substantially independent of their thickness.
En revanche, comme les films métallisés présentent de mauvaise performance pour ce qui est de l'isolation acoustique, il est nécessaire d'adjoindre une ou plusieurs couches d'isolant acoustique. L'isolant acoustique est généralement de la ouate. On the other hand, since the metallized films have poor performance in terms of acoustic insulation, it is necessary to add one or more layers of acoustic insulation. Acoustic insulation is usually wadding.
Les complexes d'isolation stratifiés du type précité présentent d'importants avantages par rapport à la laine de verre traditionnelle en matière de performance isolante, de longévité et d'absence de nocivité. The laminated insulation complexes of the aforementioned type have significant advantages over traditional glass wool in terms of insulating performance, longevity and absence of harmfulness.
Néanmoins sur certains points, les complexes multicouches du type précités ne sont pas totalement satisfaisants. Nevertheless, in some respects, the multilayer complexes of the aforementioned type are not totally satisfactory.
Ces complexes sont généralement conditionnés sous forme de rouleau. Or, du fait de la multitude de couches qui peut entrer dans leur composition, ces complexes sont conditionnés en rouleau de grand diamètre. Ceci rend leur transport ainsi que le stockage peu aisé et coûteux. These complexes are generally packaged in roll form. However, because of the multitude of layers that can enter into their composition, these complexes are packaged in roll of large diameter. This makes their transport and storage difficult and easy.
D'autre part, la pose de ces complexes peut être mal aisée. En effet, il est bien souvent nécessaire de couper le complexe à la dimension de la surface à isoler. Cette découpe se fait dans le sens transversal du complexe à l'aide généralement d'un cutter; le complexe peut alors avoir tendance à se délaminer, c'est-à-dire que les couches constituant le complexe ont tendance à se séparer les unes des autres. On the other hand, the laying of these complexes can be difficult. Indeed, it is often necessary to cut the complex to the size of the surface to be isolated. This cutting is done in the transverse direction of the complex with the help of a cutter; the complex may then tend to delaminate, i.e. the layers constituting the complex tend to separate from each other.
L'invention se propose de pallier à ces inconvénients. The invention proposes to overcome these disadvantages.
Un but de l'invention est de proposer un complexe d'isolation stratifié dont le conditionnement dont la pose est plus aisée que celle des complexes d'isolation connus. An object of the invention is to provide a laminated insulation complex whose packaging whose installation is easier than that of known insulation complexes.
Ce complexe d'isolation multicouche en forme de bande comporte deux couches externes en matière plastique métallisée, pouvant réfléchir des rayonnements de chaleur. Entre ces deux couches externes est placée une âme comprenant au moins une couche d'un matériau isolant phonique, l'âme ayant une largeur sensiblement égale à la largeur des couches externes. Selon l'invention, l'assemblage des couches entre elles est constitué par des lignes de soudages dans lesquelles toutes les couches sont jointes alternant avec des zones de non soudage dans lesquelles les couches sont libres entres elles. Ainsi, lorsque le complexe est conditionné en rouleau, l'air qui est naturellement contenu dans la ouate peut être chassé par les zones de non soudage. Le complexe selon l'invention peut être conditionné de diamètre sensiblement inférieur à un rouleau d'un complexe selon l'art antérieur. This band-shaped multilayer insulation complex comprises two outer layers of metallized plastic, which can reflect heat radiation. Between these two outer layers is placed a core comprising at least one layer of a sound insulating material, the core having a width substantially equal to the width of the outer layers. According to the invention, the assembly of the layers together is constituted by welding lines in which all the layers are joined alternating with non-welding zones in which the layers are free between them. Thus, when the complex is packaged in a roll, the air that is naturally contained in the wadding can be removed by the non-welding zones. The complex according to the invention can be packaged with a diameter substantially smaller than a roll of a complex according to the prior art.
De préférence, les lignes de soudage sont rectilignes, orientées dans le sens longitudinal du complexe et sont adjacentes à chaque bord longitudinal du complexe. Preferably, the welding lines are rectilinear, oriented in the longitudinal direction of the complex and are adjacent to each longitudinal edge of the complex.
Selon une forme de réalisation, chaque ligne de soudage est, transversalement, en regard d'une zone de non soudage. According to one embodiment, each welding line is, transversely, facing a non-welding zone.
Selon une autre forme de réalisation, chaque ligne de soudage positionnée à proximité d'un bord longitudinal du complexe est, transversalement, en regard d'une ligne de soudage positionnée à proximité d'un autre bord longitudinal du complexe. According to another embodiment, each welding line positioned near a longitudinal edge of the complex is, transversely, facing a welding line positioned near another longitudinal edge of the complex.
Selon une autre forme de réalisation, au niveau de chaque bord longitudinal du complexe, il est prévu une première série de lignes de soudages adjacente au bord longitudinal du complexe et une deuxième série de lignes de soudage décalée transversalement par rapport à la première ligne de soudage vers l'axe central du complexe dont les lignes de soudages sont alternées dans le sens longitudinal par rapport à celle de la première série. According to another embodiment, at each longitudinal edge of the complex, there is provided a first series of welding lines adjacent to the longitudinal edge of the complex and a second series of welding lines offset transversely with respect to the first welding line. towards the central axis of the complex whose lines of welding are alternated in the longitudinal direction with respect to that of the first series.
Selon au autre caractéristique de l'invention, l'assemblage des couches entre elles est assuré, en outre, par au moins un point de soudage assurant une liaison ponctuelle entre les couches. La présence de points de soudure permet de donner une tenue aux couches entre elles. Cette disposition facilite grandement la pose du complexe, puisque lorsque le complexe est coupé transversalement pour être posé les couches restent tenues entre elles pour les lignes de soudage latérales et par les points de soudage. According to the other characteristic of the invention, the assembly of the layers together is ensured, in addition, by at least one welding point providing a point connection between the layers. The presence of weld points makes it possible to give the layers resistance to each other. This arrangement greatly facilitates the laying of the complex, since when the complex is cut transversely to be laid the layers remain held together for the lateral welding lines and by the welding points.
De préférence, ces points de soudages sont distribués sur le complexe selon une distribution régulière. Preferably, these weld points are distributed over the complex in a regular distribution.
De plus, les points de soudure sont distribués régulièrement selon 15 deux lignes longitudinales parallèles. In addition, the weld spots are evenly distributed along two parallel longitudinal lines.
Dans une forme de réalisation, l'âme comprend au moins une couche de ouate synthétique, minérale, végétale ou organique. In one embodiment, the core comprises at least one layer of synthetic, mineral, vegetable or organic wadding.
Selon une possibilité, l'âme comprend au moins deux couches de ouate séparées entre elles par des couches de polypropylène aluminisé. According to one possibility, the core comprises at least two wadding layers separated from each other by layers of aluminized polypropylene.
Dans une exécution possible de l'invention, l'âme comprend six couches d'ouate séparées par cinq couches de polypropylène aluminisé. In a possible embodiment of the invention, the core comprises six layers of wadding separated by five layers of aluminized polypropylene.
Par ailleurs, les deux couches externes sont constituées de polyester métallisé sur leur face externe. In addition, the two outer layers consist of metallized polyester on their outer face.
Pour sa bonne compréhension, l'invention est décrite en référence au dessin ci-annexé représentant à titre d'exemple non limitatif plusieurs formes de réalisation d'un complexe d'isolation selon l'invention et une forme de réalisation d'un dispositif permettant de réaliser ce complexe. For a good understanding, the invention is described with reference to the attached drawing showing by way of nonlimiting example several embodiments of an insulation complex according to the invention and an embodiment of a device for to realize this complex.
Figure 1 représente en coupe transversale une forme de réalisation d'un complexe d'isolation, Figure 2 à 4 représentent en vue de dessus trois formes de réalisation du complexe d'isolation selon l'invention, Figure 5 représente en vue de coté un dispositif de fabrication d'un complexe selon l'invention. 1 represents in cross-section an embodiment of an insulation complex, FIGS. 2 to 4 show a top view of three embodiments of the insulation complex according to the invention, FIG. of manufacturing a complex according to the invention.
La figure 1 illustre, en coupe transversale, la structure du complexe 35 multicouche. Figure 1 illustrates, in cross-section, the structure of the multilayered complex.
Comme on peut le voir sur cette figure, ce complexe 1 comporte treize couches. Ces treize couches se répartissent en deux couches extérieures 2 de polyester métallisé, ces deux couches externes 2 enferment une âme 3 qui est, pour sa part, constituée de six couches d'ouate 4 entre lesquelles sont intercalées cinq couches de polypropylène aluminisé 5. As can be seen in this figure, this complex 1 comprises thirteen layers. These thirteen layers are divided into two outer layers 2 of metallized polyester, these two outer layers 2 enclose a core 3 which is, for its part, consisting of six wadding layers 4 between which are interposed five layers of aluminized polypropylene 5.
Le complexe 1, ainsi constitué, assure une réflexion de la chaleur par ses couches externes 2 métallisées et ses couches de polypropylène aluminisé 5 et assure également une isolation phonique grâce à ces six couches d'ouate 4. The complex 1, thus formed, provides heat reflection by its outer layers 2 metallized and aluminized polypropylene layers 5 and also provides a sound insulation through these six wadding layers 4.
La spécificité du complexe selon l'invention apparaît plus clairement aux figures 2 à 4. En effet, sur ces figures apparaît clairement la caractéristique selon laquelle l'assemblage des couches entre elles est réalisé par des lignes de soudage 7 qui alternent avec des zones de non soudage dans lesquelles les couches sont libres entre elles. The specificity of the complex according to the invention appears more clearly in FIGS. 2 to 4. In fact, these figures clearly show the characteristic according to which the assembly of the layers between them is achieved by welding lines 7 which alternate with zones of non-welding in which the layers are free from each other.
La figure 2 montre une première forme de réalisation dans laquelle l'assemblage du complexe est réalisé par des lignes de soudage 7 qui alternent avec des zones de non soudage; dans cette forme de réalisation, chaque ligne de soudage 7 qui est formée à proximité d'un bord longitudinal du complexe est en regard d'une autre ligne de soudage 7 qui est également à proximité d'un bord longitudinal du complexe. Chaque ligne de soudage 7 est positionnée à environ 20 millimètres du bord longitudinal du complexe. FIG. 2 shows a first embodiment in which the assembly of the complex is made by welding lines 7 which alternate with non-welding zones; in this embodiment, each welding line 7 which is formed near a longitudinal edge of the complex is facing another welding line 7 which is also near a longitudinal edge of the complex. Each welding line 7 is positioned about 20 millimeters from the longitudinal edge of the complex.
En d'autres termes, les deux lignes de soudage 7 se font face. Dans la pratique, la longueur de ces lignes de soudage est comprise entre 200 et 300 millimètres et alterne avec des zones de non soudage qui présentent une longueur également comprise entre 200 et 300 millimètres. In other words, the two welding lines 7 face each other. In practice, the length of these welding lines is between 200 and 300 millimeters and alternates with non-welding zones which have a length also between 200 and 300 millimeters.
Le fait que le soudage soit discontinu sur la longueur du complexe fait que, lorsque celui-ci est enroulé pour être stocké, l'air qui a été emprisonné entre les couches qui le constituent, peut être chassé et peut s'évacuer par les zones de non soudage. Ainsi, le complexe peut être conditionné et stocké dans un état dans lequel l'air lui a été ôté. On peut estimer que le gain, à longueur de complexe égale, est d'environ 30 % sur le diamètre d'un rouleau. Ceci est donc tout à fait significatif. The fact that the welding is discontinuous along the length of the complex means that, when the latter is wound up to be stored, the air which has been trapped between the layers which constitute it can be driven out and can be evacuated by the zones. non-welding. Thus, the complex can be conditioned and stored in a state in which the air has been removed. It can be estimated that the gain, at equal complex length, is about 30% over the diameter of a roll. This is therefore quite significant.
On note également que le complexe présente des points de soudage 8 qui, dans l'exemple représenté, sont distribués sur deux lignes longitudinales; les points de soudage 8 sont répartis environ tous les 600 millimètres. L'intérêt de ces points de soudage 8 est que, lorsque le complexe doit être découpé transversalement pour être adapté à son lieu de pose, ces points de soudage 8 permettent de conserver une tenue des différentes couches constituant le complexe, ceci évite tout délaminage du complexe. It is also noted that the complex has welding points 8 which, in the example shown, are distributed over two longitudinal lines; the welding points 8 are distributed approximately every 600 millimeters. The advantage of these welding points 8 is that, when the complex has to be cut transversely to be adapted to its place of installation, these welding points 8 make it possible to preserve a holding of the different layers constituting the complex, this avoids any delamination of the complex.
La figure 3 montre une autre forme de réalisation du complexe dans lequel, si l'on se réfère à la direction transversale du complexe, une ligne de soudage 7 se trouve en regard d'une zone de non soudage. FIG. 3 shows another embodiment of the complex in which, if one refers to the transverse direction of the complex, a welding line 7 is opposite a non-welding zone.
La figure 4 montre encore une autre forme de réalisation dans laquelle on trouve des lignes de soudage 7a alternant avec des zones de non soudage sensiblement comme cela est représenté à la figure 2, mais est également prévu de disposer en retrait des zones de non soudage une ligne de soudage 7b décalée en direction du centre du complexe. FIG. 4 shows yet another embodiment in which welding lines 7a alternating with zones of non-welding substantially as shown in FIG. 2 are found, but it is also envisaged to set back from the non-welding zones a welding line 7b offset towards the center of the complex.
Ceci permet de ménager entre les lignes de soudage 7a, 7b un espace par lequel l'air peut s'échapper, lorsque le complexe est conditionné 15 sous forme de rouleau. This makes it possible to provide between the welding lines 7a, 7b a space through which the air can escape, when the complex is conditioned in the form of a roll.
La figure 5 illustre schématiquement une installation de réalisation du complexe d'isolation multicouche. Chaque couche appelée à entrer dans la composition du complexe est amenée sur une bobine qui est déroulée de manière à se superposer et à former un complexe qui sera soudé et découpé en fin de process. FIG. 5 schematically illustrates an installation for producing the multilayer insulation complex. Each layer called to enter the composition of the complex is brought on a coil which is unrolled so as to be superimposed and to form a complex which will be welded and cut at the end of the process.
Si l'on se reporte à la figure 5, on peut voir que le dispositif comprend plusieurs berceaux disposés en série supportant des bobines; chaque bobine est entraînée en rotation par un système de cônes motorisés. Referring to Figure 5, it can be seen that the device comprises several cradles arranged in series supporting coils; each coil is rotated by a system of motorized cones.
A l'extrémité amont du dispositif, on peut voir que la bobine d'extrémité supporte une couche de polyester métallisé 2 qui va constituer l'une des faces extrêmes du complexe, les couches d'ouate 4 qui, dans l'exemple représenté, sont au nombre de six, sont déroulées à partir de bobines disposées par pair. En effet, les couches d'ouate 4 sont sensiblement plus épaisses que les couches de polypropylène 5 et de polyester 2r, ce qui fait que les bobines d'ouate sont celles qui sont rechargées le plus fréquemment. On note également la présence de cinq bobines de polypropylène aluminisé 5 qui s'intercale entre les paires de bobine d'ouate. At the upstream end of the device, it can be seen that the end coil supports a layer of metallized polyester 2 which will constitute one of the extreme faces of the complex, the wadding layers 4 which, in the example shown, are six in number, are unwound from coils arranged in pairs. Indeed, the wadding layers 4 are substantially thicker than the layers of polypropylene and polyester 2r, so that the wadding coils are those that are recharged most frequently. There are also five aluminized polypropylene coils 5 which are interposed between the cotton bobbin pairs.
Enfin, une dernière bobine de polyester métallisé 2 vient recouvrir l'âme constituée de cinq couches de polypropylène aluminisé et des dix 35 couches de ouate. Finally, a final metallized polyester spool 2 covers the core consisting of five layers of aluminized polypropylene and ten layers of wadding.
Un poste de soudure 10 à ultrasons réalise les points de soudage et les lignes de soudage, grâce à des sonotrodes. An ultrasonic welding station 10 carries out the welding points and the welding lines, thanks to sonotrodes.
Enfin, un poste de conditionnement 12 réalise l'enroulement des rouleaux la découpe du complexe. Finally, a packaging station 12 carries out the winding of the rolls and the cutting of the complex.
L'invention fournit ainsi un complexe qui peut être conditionné de façon avantageuse puisque, à longueur constante, un rouleau de complexe selon l'invention présente un diamètre environ inférieur à celui d'un complexe selon l'art antérieur. The invention thus provides a complex which can be advantageously conditioned since, at constant length, a complex roll according to the invention has a diameter less than that of a complex according to the prior art.
En outre, la mise en oeuvre de ce complexe au moment de sa pose 10 est sensiblement plus aisée puisque le risque de délaminage des différentes couches est écarté grâce aux points de soudure. In addition, the implementation of this complex at the time of its installation 10 is substantially easier since the risk of delamination of the different layers is eliminated through the weld points.
Bien entendu, l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus à titre d'exemples non limitatifs, mais elle en embrasse au contraire toutes les formes de réalisation. Ainsi, il est possible d'envisager d'autres formes pour les lignes de soudage, celles-ci pourraient être curvilignes, ou sinusoïdales. Of course, the invention is not limited to the various embodiments described above as non-limiting examples, but it encompasses all the embodiments. Thus, it is possible to consider other forms for welding lines, they could be curvilinear, or sinusoidal.
