Description
PANNEAU COMPOSITE ISOLANT L'invention se rapporte à un panneau composite isolant. Le cout de l'énergie devenant de plus en plus cher, l'isolation des habitations est un élément important pris en compte par les constructeurs. The invention relates to an insulating composite panel. As the cost of energy is becoming more expensive, the insulation of homes is an important factor taken into account by the builders.
Il existe différents matériaux d'isolations connus telle la laine de verre ou de mouton, la laine de roche, le polystyrène extrudé etc. Chacun de ces matériaux possède un pouvoir isolant appelé conductivité thermique qui combiné avec l'épaisseur de l'isolant va donner la résistance R thermique du produit. There are various known insulation materials such as glass wool or sheep wool, rock wool, extruded polystyrene and so on. Each of these materials has an insulating power called thermal conductivity which combined with the thickness of the insulation will give the thermal resistance R of the product.
Ainsi plus l'épaisseur d'isolant est importante, pour un matériau donné, plus on limite les échanges thermiques. Non seulement le choix du type de matériau est important mais il faut également choisir sa présentation Certains de ces matériaux ne sont pas en mis forme et sont simplement déposés sur le plancher de nos greniers (par exemple les laines minérales).. En effet de la laine minérale en « vrac » peut être utilisée dans les combles « perdus » mais pas en sous pente. Les mêmes matériaux peuvent être commercialisés sous forme de bandes ou de panneaux qui permet de les manipuler plus facilement. Thus, the greater the insulation thickness, for a given material, the more the thermal exchanges are limited. Not only the choice of the type of material is important but it is also necessary to choose its presentation Some of these materials are not in form and are simply deposited on the floor of our attics (for example mineral wool) .. Indeed the mineral wool "loose" can be used in the attic "lost" but not on the slope. The same materials can be marketed in the form of strips or panels which makes them easier to handle.
On retrouve également des panneaux composites constitués par une plaque rigide généralement en plâtre sur laquelle est fixée une couche d'un matériau isolant tel le polystyrène. Ces panneaux composites ont généralement au plus une épaisseur de 100 à 150 mm. Ils sont destinés à être collés sur un mur. There are also composite panels consisting of a rigid plate generally plaster on which is fixed a layer of an insulating material such as polystyrene. These composite panels generally have at most a thickness of 100 to 150 mm. They are intended to be stuck on a wall.
Par rapport aux matériaux comme les laines, ces panneaux sont encombrants tant pour le transport que pour la manipulation. En effet, l'isolant utilisé ne peut être compressé contrairement à la laine de verre qui est souvent conditionnée en rouleaux afin d'en réduire le volume ce qui est intéressant pour le transport. Compared to materials such as wool, these panels are bulky for both transport and handling. Indeed, the insulation used can not be compressed unlike glass wool which is often packaged in rolls to reduce the volume which is interesting for transport.
Augmenter la couche d'isolant de ces panneaux composites n'est pas une difficulté sur le plan fabrication mais a un impact sur le transport et la manipulation. L'invention se propose d'apporter une solution. A cet effet l'invention se rapporte à un panneau composite comprenant deux plaques rigides entre lesquelles est disposé au moins un isolant caractérisé en ce que l'isolant est constituée d'alvéoles contigües à la fois dans le plan du panneau et l'épaisseur du panneau et les parois des alvéoles sont déformables dans le sens de l'éloignement ou du rapprochement des plaques rigides l'une par rapport à l'autre. Increasing the insulation layer of these composite panels is not a manufacturing problem but has an impact on transportation and handling. The invention proposes to provide a solution. For this purpose the invention relates to a composite panel comprising two rigid plates between which is disposed at least one insulator characterized in that the insulation consists of contiguous cells both in the plane of the panel and the thickness of the panel and the walls of the cells are deformable in the direction of the distance or approximation of the rigid plates relative to each other.
L'invention sera bien comprise à la lecture de la description ci après faite à titre d'exemple non limitatif en regard du dessin qui représente : FIG 1 Vue en coupe d'un panneau composite en place au niveau d'un toit FIG 2 Vue en coupe d'un panneau composite en position compact FIG3 à FIG 6 : différentes solutions pour les alvéoles de l'isolant FIG 7 : Un exemple particulier de panneau. En se reportant au dessin, on voit un panneau 1 composite isolant monté en toiture. Ce panneau comprend deux plaques rigides 2A ,2B entre lesquelles est disposé au moins un isolant 3. The invention will be better understood on reading the following description given by way of non-limiting example with reference to the drawing which represents: FIG 1 Sectional view of a composite panel in place at a roof FIG 2 View in section of a composite panel in compact position FIG3 to FIG 6: different solutions for the cells of the insulator FIG. 7: A particular example of a panel. Referring to the drawing, we see an insulating composite panel 1 mounted on the roof. This panel comprises two rigid plates 2A, 2B between which is disposed at least one insulator 3.
Par plaque rigide, on comprendra, par exemple, une plaque de plâtre homogène couverte par exemple par une feuille de parement ou encore un élément plan multicouche pouvant lui même comprendre au moins une couche d'isolant. Ces plaques ont notamment comme fonctionnalité de constituer un support à peindre ou à recouvrir d'un revêtement décoratif. Selon l'invention, l'isolant 3 est constitué d'alvéoles 3A contigües à la fois dans le plan et l'épaisseur du panneau et les alvéoles sont déformables dans le sens de l'éloignement ou du rapprochement des plaques rigides l'une par rapport à l' autre. By rigid plate, it will be understood, for example, a homogeneous plasterboard covered for example by a facing sheet or a multilayer planar element may itself include at least one layer of insulation. These plates have the particular function of constituting a support to be painted or covered with a decorative coating. According to the invention, the insulator 3 consists of cavities 3A contiguous both in the plane and the thickness of the panel and the cells are deformable in the direction of the distance or the approximation of the rigid plates one by report to the other.
Ces alvéoles déformables vont relier les plaques entre elles et la déformation des alvéoles va permettre au panneau composite d'être transporté et manipulé dans un état d'épaisseur réduite pour après mise en place se développer. Les alvéoles peuvent être tubulaires ouvertes ou fermées. Dans le cas où elles sont fermées, il y a lieu de prévoir un moyen assurant une perméabilité à l'air permettant de remplir les alvéoles lors du déploiement du panneau. Cette perméabilité est celle naturelle de la feuille de matière utilisé ou obtenu par la présence de trous ou de valves. Dans une forme de réalisation (figure 3) , les alvéoles sont délimitées par des parois rigides 30A, 30B reliées deux a deux par une zone de pliage 30C comme un accordéon. Vue en coupe transversale, en position écartée des plaques, l'alvéole a une section en losange qui va tendre à s'aplatir lorsqu'on rapproche les plaques. Les alvéoles de la figure 3 peuvent être constituées cependant par des parois semi-souples. These deformable cells will connect the plates together and the deformation of the cells will allow the composite panel to be transported and manipulated in a state of reduced thickness for after implementation develop. The cells may be tubular open or closed. In the case where they are closed, it is necessary to provide means ensuring air permeability to fill the cells during deployment of the panel. This permeability is the natural one of the sheet of material used or obtained by the presence of holes or valves. In one embodiment (Figure 3), the cells are delimited by rigid walls 30A, 30B connected two by two by a folding zone 30C as an accordion. Cross-sectional view, in the spaced apart position of the plates, the cell has a diamond-shaped section that will tend to flatten when the plates are brought closer together. The cells of FIG. 3 may however consist of semi-flexible walls.
Sur la figure 41a section de l'alvéole est circulaire, les parois sont souples. Une section polygonale, par exemple triangulaire (fig 5) est possible. In Figure 41a section of the cell is circular, the walls are flexible. A polygonal section, for example triangular (FIG. 5), is possible.
Egalement une alvéole peut être carrée ou rectangulaire. Elle est alors délimitée par des parois rigides 300A et des parois souples 300B. Dans ce dernier cas les parois rigides sont celles qui sont sensiblement parallèles aux plaques (fig 6). Pour ces alvéoles carrées ou rectangulaires, les parois dans l'axe de déplacement des plaques doivent pouvoir se déformer pour permettre un empilement des cloisons rigides. Les formes en losange ou carrée ou rectangle seront plus simple à mettre en oeuvre pour une continuité transversale.Les cloisons rigides parallèles au plaque peuvent être d'étendue identique à la plaque. Ainsi, la variation d'épaisseur du panneau composite entre les deux positions extrêmes peut être très importante sans pour autant occuper une forte épaisseur en position compact. L'épaisseur minimale théorique entre les plaques sera égale au nombre d'alvéoles (dans le sens de l'épaisseur) multiplié par deux fois l'épaisseur de la paroi. On peut ainsi minimiser les couts de transport, de manipulation et de découpe. 15 En effet les panneaux seront transportés en position compact pour être déployés lors de la pose Les alvéoles d'une colonne d'alvéoles qui s'étendent entre deux plaques sont nécessairement solidarisées l'une avec l'autre mais les colonnes entre elles sont ou ne sont pas solidaires entre elles. La solidarisation peut être réalisée par un 20 adhésif ou une ligne de points de couture etc. Chaque colonne d'alvéoles est par exemple formée de deux feuilles de matières reliées localement par des lignes d'assemblage pour délimiter des volumes tubulaires lesquels volumes tubulaires peuvent être partitionnés en longueur par d'autres lignes d'assemblage. Also a cell may be square or rectangular. It is then delimited by rigid walls 300A and flexible walls 300B. In the latter case the rigid walls are those which are substantially parallel to the plates (FIG. 6). For these square or rectangular cells, the walls in the axis of displacement of the plates must be able to deform to allow a stack of rigid walls. The diamond or square or rectangle shapes will be simpler to implement for transverse continuity. The rigid partitions parallel to the plate may be of identical extent to the plate. Thus, the thickness variation of the composite panel between the two extreme positions can be very large without occupying a large thickness in compact position. The theoretical minimum thickness between the plates will be equal to the number of cells (in the direction of the thickness) multiplied by twice the thickness of the wall. It can thus minimize the costs of transport, handling and cutting. Indeed, the panels will be transported in compact position to be deployed during installation The cells of a column of cells that extend between two plates are necessarily secured to one another but the columns between them are or are not in solidarity with each other. The joining can be done by an adhesive or a line of stitches etc. Each column of cells is for example formed of two sheets of materials connected locally by assembly lines to delimit tubular volumes which tubular volumes can be partitioned in length by other assembly lines.
Du fait que les alvéoles soient déformables, on peut limiter l'écartement des deux plaques soit avec des moyens 5 type lien reliant les faces en vis-à-vis des plaques soit avec des bandes entourant le panneau comme une ceinture. Dans certain cas, ce sont des butées 6 de la structure porteuse qui limiteront 5 l'écartement des plaques. On a donc une solution qui permet de constituer des panneaux isolants de faible épaisseur pour le transport, la coupe et la manutention et qui après mise ne oeuvre ont une épaisseur beaucoup plus grande. Egalement un même panneau peut convenir pour différentes épaisseurs.Because the cells are deformable, it is possible to limit the spacing of the two plates either with connection-type means 5 connecting the faces facing the plates or with strips surrounding the panel as a belt. In certain cases, it is abutments 6 of the supporting structure which will limit the spacing of the plates. So we have a solution that allows to build thin insulating panels for transportation, cutting and handling and after implementation have a much greater thickness. Also the same panel may be suitable for different thicknesses.
10 Le matériau utilisé pour former les alvéoles sera de préférence un matériau mauvais conducteur de la chaleur. La multitude d'alvéoles va limiter la conduction. Outre la résistance thermique, on obtient des résultats sur le plan phonique. Les colonnes d'alvéoles qui s'étendent entre les plaques sont localement 15 associées transversalement deux à deux. Par exemple, les colonnes d'alvéoles sont reliées tous les cinq alvéoles ou seront toutes reliées selon le mode de fabrication. Cela confère une tenue latérale. Les panneaux seront aux dimensions standards des panneaux du commerce c'est-à-dire, par exemple de l'ordre de 1200*2500 mm.The material used to form the cells will preferably be a poor heat conductor material. The multitude of cells will limit the conduction. In addition to the thermal resistance, phonic results are obtained. The cell columns that extend between the plates are locally associated transversely in pairs. For example, the cell columns are connected to all five cells or will all be connected according to the method of manufacture. This gives a lateral hold. The panels will be the standard dimensions of commercial panels that is to say, for example of the order of 1200 * 2500 mm.
20 Selon les exemples précédents, les alvéoles s'étendent entre les faces en vis à vis des plaques. Il est possible de fractionner cette couche épaisse d'alvéoles en deux sous couches en incorporant une paroi de séparation 10 épaisse et/ou lourde qui va servir à améliorer l'isolation phonique de par sa masse. Le terme épais est à comparer avec l'épaisseur de la paroi de l'alvéole. 25 According to the preceding examples, the cells extend between the faces facing the plates. It is possible to split this thick layer of cells into two sub-layers by incorporating a thick and / or heavy partition wall 10 which will serve to improve the sound insulation by its mass. The term thick is to be compared with the thickness of the wall of the cell. 25
