STRUCTURE COMPACTE D'ISOLATION EXTERIEURE DE PAROIS ET
PANNEAUX ISOLANTS DESTINES A SA REALISATION.COMPACT EXTERIOR WALL INSULATION STRUCTURE AND
INSULATING PANELS FOR ITS REALIZATION.
L'invention se rapporte à la mise en place d'une structure isolante à l'extérieur d'une paroi de bâtiment ou autre installation domestique ou industrielle. Une telle structure doit de préférence être légère et posséder, en plus de ses propriétés d'isolation thermique, une bonne étanchéité et une bonne résistance au feu, à la corrosion, à l'humidité, à la compression, aux chocs, ètc...The invention relates to the installation of an insulating structure outside a building wall or other domestic or industrial installation. Such a structure should preferably be light and have, in addition to its thermal insulation properties, good sealing and good resistance to fire, corrosion, humidity, compression, shock, etc. .
I1 est connu de réaliser de telles structures à l'aide d'enduits divers, éventuellement armés d'un grillage. On a par exemple constitué l'enduit de mortiers hydrauliques ceux-ci ont alors dû, quand une protection particulièrement efficace et résistant bien aux chocs thermiques et mécaniques était souhaitée, être projetés sur une barrière intermédiaire afin de ménager une lame d'air ventilée entre l'enduit et la paroi à protéger, et la réalisation s'en trouve compliquée. I1 is known to produce such structures using various plasters, possibly armed with a mesh. For example, a plaster of hydraulic mortars was formed, which, when a particularly effective protection resistant to thermal and mechanical shocks was desired, had to be sprayed onto an intermediate barrier in order to provide a ventilated air space between the coating and the wall to be protected, and the realization is complicated.
Certains revêtements plastiques, en particulier en mousse de polyuréthanne, ont été utilisés et réalisés par projection ;- les caractéristiques d'isolation obtenues dépendent alors largement des conditions atmosphériques qni règnent au moment où s'effectue la projection, ce qui est un incoacré- nient important.Certain plastic coverings, in particular polyurethane foam, have been used and produced by spraying; - the insulation characteristics obtained then largely depend on the atmospheric conditions which prevail at the time when the spraying takes place, which is an inconsistency important.
L'invention a pour objet une structure d'isolation exterieure caractérisée par des panneaux constitués dune patie- re isolante, de préférence de la mousse de polyuréthanne, injectée dans une structure métallique composée d'un premier treillis noyé dans ladite matière et situé au voisinage de la face du panneau destinée à venir en contact avec la paroi à protéger, d'un second treillis situé à l'extérieur de ladite matière au voisinage de la face opposée du panneau et de fils qui relient les deux treillis à travers ladite pa- tière, lesdits panneaux étant fixés à ladite paroi par clouage et assemblés entre eux par réunion des seconds treillis au moyen de bandes de liaison elles-meaes en treillis métallique, à la suite de quoi un revêtement cowpo- sé d'un ou plusieurs enduits appropriés est projeté sur le deuxième treillis.The subject of the invention is an external insulation structure characterized by panels made up of an insulating pad, preferably polyurethane foam, injected into a metallic structure composed of a first lattice embedded in said material and located in the vicinity of the face of the panel intended to come into contact with the wall to be protected, of a second trellis located outside of said material in the vicinity of the opposite face of the panel and of wires which connect the two trellises through said pa- the said panels being fixed to the said wall by nailing and assembled together by joining the second trellis by means of connecting bands themselves in a metallic trellis, after which a cowposed coating of one or more suitable plasters is projected onto the second trellis.
L'invention a encore pour objet un panneau destiné à la réalisation d'une telle structure d'isolation.The invention also relates to a panel intended for the production of such an insulation structure.
Les particularités et avantages de l'invention apparaltront clairement à la lumière de la description ci-après.The features and advantages of the invention will become apparent in the light of the description below.
Au dessin annexé
La figure 1 est une vue en coupe d'une structure
conforme à un mode d'exécution de l'invention, et
la figure 2 représente quatre panneaux assemblés
entre eux.In the attached drawing
Figure 1 is a sectional view of a structure
in accordance with an embodiment of the invention, and
Figure 2 shows four panels assembled
between them.
Le panneau 1 représenté à la figure 1 est en mousse de polyuréthanne et a par exemple une épaisseur de 95 mm, une longueur de 3 m et une largeur de 1 m 20. La mousse est injectée dans une ossature d'acier comportant un preitier treillis 2 noyé dans la mousse, à une distance de 30 mm par exemple de la face 10 de contact avec le mur M, un second treillis 3 situé à l'extérieur, à 10 mm par exemple de la face opposée du panneau, et des fils de liaison 4, 5 qui traversent le panneau perpendiculairement à ses faces. A titre d'exemple, la maille des treillis aura 55 mm de côté et il y aura à peu près autant de fils de liaison que de mailles, la structure métallique ainsi réalisée étant une structure tridimensionnelle régulière.The panel 1 shown in Figure 1 is made of polyurethane foam and has for example a thickness of 95 mm, a length of 3 m and a width of 1 m 20. The foam is injected into a steel frame comprising a first trellis 2 embedded in the foam, at a distance of 30 mm for example from the face 10 in contact with the wall M, a second trellis 3 located outside, 10 mm for example from the opposite face of the panel, and wires 4, 5 which cross the panel perpendicular to its faces. For example, the mesh of the trellis will be 55 mm on a side and there will be approximately as many connecting wires as there are meshes, the metal structure thus produced being a regular three-dimensional structure.
La face 10 est de préférence alvéolée, les nervures 101, 102 qui définissent les alvéoles ayant par exemple 15 mm d'épaisseur. De l'air immobile se trouve ainsi emprisonné entre le panneau et le mur à protéger. Outre l'effet d'isolation phonique, cette face alvéolée constitue une couche relativement souple disposée entre les couches diverses du panneau, couche qui absorbe les déformations de l'immeuble porteur sans les transmettre à la face extérieure du panneau, donc sans donner naissance à des fissures ou nuire d'aucune manière à l'imperméabilité de la structure.The face 10 is preferably dimpled, the ribs 101, 102 which define the dimples having for example 15 mm thick. Still air is thus trapped between the panel and the wall to be protected. In addition to the soundproofing effect, this honeycomb face constitutes a relatively flexible layer placed between the various layers of the panel, a layer which absorbs the deformations of the load-bearing building without transmitting them to the outside face of the panel, therefore without giving rise to cracks or in any way affect the waterproofing of the structure.
A la figure 2, on a représenté quatre panneaux juxtaposés, dont les deuxième treillis sont reliés entre eux à leurs jonctions par des bandes telles que 6, 7 elles-mêmes en treillis. Il suffit d'agrafer ces bandes, tous les 25 cm par exemple, sur les deuxième treillis des panneaux pour obtenir la fixation.In Figure 2, there are shown four juxtaposed panels, the second trellis of which are connected to each other at their junctions by strips such as 6, 7 themselves in trellis. It suffices to staple these strips, every 25 cm for example, on the second trellis of the panels to obtain the fixing.
Auparavant, les panneaux ont été fixés à l'aide de clous qui traversent les panneaux et s'enfoncent dans les murs.Previously, the panels were fixed using nails which pass through the panels and sink into the walls.
Sur les pourtours de la structure, l'on dispose des cornières d'arrêt que l'on agrafe au deuxième treillis.On the edges of the structure, there are stop angles which are stapled to the second trellis.
Un revêtement est réalisé une fois la pose terminée. I1 est avantageusement constitué d'une couche principale 8 (figure 1) de mortier hydraulique au ciment, ayant par exemple 2Q mm d'épaisseur et d'une couche extérieure décorative 9, ayant par exemple 4 à 8 mm d'épaisseur. La couche 8 est projetée sur le second treillis 3, qui lui sert d'armature.A coating is made once the installation is complete. I1 advantageously consists of a main layer 8 (Figure 1) of hydraulic cement mortar, for example 2Q mm thick and a decorative outer layer 9, for example 4 to 8 mm thick. The layer 8 is projected onto the second trellis 3, which serves as a reinforcement for it.
Elle noie donc complètement l'armature en pénétrant dans ses mailles, grâce à quoi la structure supportera les chocs thermiques, malgré l'absence de lame d'air ventilée entre la matière isolante du panneau et l'enduit.It therefore completely drowns the reinforcement by entering its meshes, thanks to which the structure will withstand thermal shocks, despite the absence of a ventilated air gap between the insulating material of the panel and the coating.
On notera qu'une telle structure est imperméabilisée par l'enduit 8 et qu'il est immédiatement possible d'effectuer les travaux à l'intérieur de l'immeuble.It will be noted that such a structure is waterproofed by the coating 8 and that it is immediately possible to carry out the work inside the building.
Une fois la pause des panneaux isolants réalisée, il n'y a aucune obligation immédiate des revêtements de protection.Once the insulation panels have been broken, there is no immediate obligation for protective coatings.
La pose, qui n exige que des opérations de clouage et d'agrafage et ne requiert aucune préparation du support, peut se faire même sous intempéries, à l'exclusion, bien entendu, de la projection de l'enduit. Le panneau isolant, réalisé en usine, a des propriétés constantes.The installation, which requires only nailing and stapling operations and requires no preparation of the support, can be done even in inclement weather, to the exclusion, of course, of the projection of the coating. The insulating panel, produced in the factory, has constant properties.
A titre d'exemple, on a pu obtenir, au moyen d'un panneau tel que défini ci-dessus ayant une masse volumique de 35,6 kg/m3 pour l'isolant, une contrainte critique moyenne de 0,98 daN/cm2, un écrasement moyen à la charge critique de 3,5, une contrainte moyenne à 10 % d'écrasement de 1,10 daN/cm2, un indice conventionnel moyen de perméabilité à la vapeur d'eau de 208 et une résistance à la chute de billes d'acier définie par un diamètre d'empreinte de 13,8 mm pour une bille de 500 g tombant d'une hauteur de 0,60 m et'un diamètre d'empreinte de 19,3 mm pour une bille de 1000 g tombant d'une hauteur de 1 m.For example, it was possible to obtain, by means of a panel as defined above having a density of 35.6 kg / m3 for the insulation, an average critical stress of 0.98 daN / cm2 , an average crushing at critical load of 3.5, an average stress at 10% of crushing of 1.10 daN / cm2, a conventional average index of permeability to water vapor of 208 and a resistance to falling steel balls defined by a footprint diameter of 13.8 mm for a 500 g ball falling from a height of 0.60 m and a footprint diameter of 19.3 mm for a ball of 1000 g falling from a height of 1 m.
On notera que la structure décrite peut être supportée par une maçonnerie traditionnelle, enduite ou non, en briques pleines, en blocs de béton pleins ou creux, etc... It will be noted that the structure described can be supported by traditional masonry, coated or not, in solid bricks, in solid or hollow concrete blocks, etc.
