Description

L'invention concerne un élément de vêture destiné à être appliqué sur la surface extérieure d'un mur de bâtiment, présentant un bord supérieur et un bord inférieur et comprenant une couche d'isolant thermique et un parement adhérant à la face externe de celle-ci.The invention relates to a covering element intended to be applied to the exterior surface of a building wall, having an upper edge and a lower edge and comprising a layer of thermal insulation and a facing adhering to the external face thereof. this.

La vêture est réalisée par la juxtaposition et la superposition de tels éléments de vêture. Il s'agit d'un moyen simple et économique d'isolation des bâtiments. Elle présente un aspect esthétique, par exemple comparable à celui d'un mur en pierre, grâce à l'appareillage constitué par les parements.The cladding is carried out by the juxtaposition and the superposition of such cladding elements. It is a simple and economical way of insulating buildings. It has an aesthetic appearance, for example comparable to that of a stone wall, thanks to the equipment formed by the facings.

Des canaux orientés de haut en bas peuvent être prévus entre la couche d'isolant et le parement de l'élément de vêture pour permettre l'évacuation de l'eau produite par la condensation de vapeur diffusant depuis l'intérieur du bâtiment, dans le cas où le parement est imperméable à la vapeur.Channels oriented from top to bottom can be provided between the insulation layer and the facing of the covering element to allow the evacuation of the water produced by the condensation of vapor diffusing from inside the building, into the if the siding is vapor impermeable.

Dans les éléments de vêture connus de ce type qui sont décrits dans le document FR-A-2546560, les canaux d'évacuation sont formés par des rainures ménagées dans la face externe de la couche d'isolant, qui débouchent dans le bord supérieur et dans le bord inférieur de l'élément. Il en résulte que l'eau de pluie qui s'infiltre entre le bord inférieur et le bord supérieur respectivement de deux éléments de vêture superposés peut pénétrer et s'écouler dans les rainures de l'élément inférieur, ce qui peut entraîner des dégâts en cas de gel. La pénétration de l'eau de pluie est facilitée lorsque les parements ne sont pas jointifs, en particulier lorsque la couche d'isolant s'étend au-delà du parement vers le haut au bord supérieur et/ou vers le bas au bord inférieur, l'intervalle entre les parements de deux éléments de vêture superposés offrant un passage direct entre l'atmosphère extérieure et les extrémités supérieures des rainures de l'élément inférieur.In the known cladding elements of this type which are described in document FR-A-2546560, the evacuation channels are formed by grooves made in the external face of the layer of insulation, which open into the upper edge and in the lower edge of the element. As a result, rainwater which infiltrates between the lower edge and the upper edge respectively of two superimposed clothing elements can penetrate and flow into the grooves of the lower element, which can cause damage in freezing case. The penetration of rainwater is facilitated when the facings are not contiguous, in particular when the layer of insulation extends beyond the facing upwards at the upper edge and / or downwards at the lower edge, the interval between facing of two superimposed clothing elements providing a direct passage between the external atmosphere and the upper ends of the grooves of the lower element.

Le but de l'invention est de remédier à cet inconvénient.The object of the invention is to remedy this drawback.

Ce résultat est obtenu, selon l'invention, en ce que les canaux débouchent uniquement dans le bord inférieur de l'élément.This result is obtained, according to the invention, in that the channels open out only in the lower edge of the element.

Ces canaux, qui peuvent être formés par des rainures ménagées dans la face externe de la couche d'isolant, ont par exemple une profondeur dans la direction perpendiculaire à la surface du mur qui décroît progressivement depuis le bord inférieur pour s'annuler à une certaine distance du bord supérieur. Cette profondeur peut en particulier varier sensiblement linéairement d'une extrémité à l'autre des canaux. Ceux-ci peuvent alors être réalisés, sous forme de rainures, au moyen d'un fil chaud introduit dans la couche d'isolant en polystyrène expansé, à partir de sa face externe, sous une inclinaison appropriée.These channels, which can be formed by grooves made in the external face of the insulation layer, have for example a depth in the direction perpendicular to the surface of the wall which decreases progressively from the lower edge to cancel out at a certain distance from the upper edge. This depth can in particular vary substantially linearly from one end to the other of the channels. These can then be produced, in the form of grooves, by means of a hot wire introduced into the layer of expanded polystyrene insulation, from its external face, at an appropriate inclination.

Comme il résulte de l'exposé ci-dessus, l'invention est utile plus particulièrement, mais non exclusivement, dans le cas où la couche d'isolant s'étend au-delà du parement vers le haut au bord supérieur et/ou vers le bas au bord inférieur.As follows from the description above, the invention is useful more particularly, but not exclusively, in the case where the layer of insulation extends beyond the facing upwards at the upper edge and / or towards bottom to bottom edge.

Other characteristics and advantages of the invention will emerge from the detailed description below and the attached drawings, in which:
  • - Figure 1 is a partial perspective view of a piece of clothing in progress;
  • - Figure 2 is a partial view of the cladding, in cross section through a vertical plane, showing elements of known clothing;

  • - Figure 4 is a front view of the element of Figure 3.

La vêture représentée aux figures 1 et 2, destinée à l'isolation et/ou à la décoration d'un mur extérieur 1 de bâtiment, comprend une multiplicité de supports allongés profilés 2 fixés sur le mur, s'étendant horizontalement le long de celui-ci et régulièrement espacés en hauteur. Chacun des profilés 2 comprend une âme 3 disposée horizontalement, une première aile verticale 4 s'étendant vers le haut à partir de l'âme 3 et une seconde aile verticale 5 s'étendant vers le haut et vers le bas, symétriquement par rapport au plan de l'âme 3, sous forme de deux demi-ailes 6 et 7 respectivement, à l'opposé de l'aile 4 par rapport à la largeur de l'âme. L'aile 4 est appliquée contre le mur 1 auquel elle est fixée au moyen de vis 8 s'engageant dans des trous 9 répartis le long de cette aile, tandis que la seconde aile 5 est écartée du mur. La longueur des profilés étant généralement inférieure à la largeur du mur à recouvrir, plusieurs profilés sont disposés dans le prolongement l'un de l'autre pour former des rails horizontaux sensiblement continus sur la largeur du mur.The cladding shown in Figures 1 and 2, intended for the insulation and / or decoration of an exterior wall 1 of a building, comprises a multiplicity of elongated profiled supports 2 fixed to the wall, extending horizontally along that here and regularly spaced in height. Each of the sections 2 comprises a core 3 arranged horizontally, a first vertical wing 4 extending upwards from the core 3 and a second vertical wing 5 extending upwards and downwards, symmetrically with respect to the plane of the core 3, in the form of two half-wings 6 and 7 respectively, opposite the wing 4 with respect to the width of the core. The wing 4 is applied against the wall 1 to which it is fixed by means of screws 8 engaging in holes 9 distributed along this wing, while the second wing 5 is spaced from the wall. The length of the profiles being generally less than the width of the wall to be covered, several profiles are arranged in the extension of one another to form substantially continuous horizontal rails over the width of the wall.

La vêture comprend également une multiplicité d'éléments de revêtement 10 formés chacun d'une couche isolante de polystyrène expansé 11 et d'un parement extérieur 12 en fibrociment stabilisé 12 collé sur la face externe de la couche 11. Chaque élément 10 a la forme d'une plaque rectangulaire dont la hauteur est très légèrement inférieure au pas des rails formés par les profilés 2. Le revêtement du mur est réalisé par la superposition d'étages formés chacun par des éléments 10 juxtaposés, maintenus entre deux rails voisins. L'immobilisation des éléments d'un étage est assurée par la pénétration des demi-ailes 7 des profilés du rail supérieur dans des rainures d'assemblage 17 ménagées verticalement et longitudinalement dans la couche de polystyrène 11 à partir du côté supérieur des éléments 10, et par pénétration des demi-ailes 6 du rail inférieur dans des rainures analogues 16 ménagées à partir du côté inférieur des éléments 10. La position des rainures d'assemblage et les dimensions des profilés sont telles que la couche de polystyrène 11 est sensiblement adjacente au mur 2. Les éléments 10 sont disposés en quinconce, les éléments d'un étage étant décalés latéralement d'un demi-pas par rapport à ceux des étages voisins. Cette disposition est également facultative.The cladding also comprises a multiplicity of covering elements 10 each formed from an insulating layer of expanded polystyrene 11 and from an external facing 12 made of stabilized fiber cement 12 bonded to the external face of the layer 11. Each element 10 has the form of a rectangular plate whose height is very slightly lower than the pitch of the rails formed by the profiles 2. The wall covering is produced by the superposition of stages each formed by juxtaposed elements 10, held between two neighboring rails. The immobilization of the elements of a stage is ensured by the penetration of the half-wings 7 of the profiles of the upper rail into assembly grooves 17 formed vertically and longitudinally in the polystyrene layer 11 from the upper side of the elements 10, and by penetration of the half-wings 6 of the lower rail into similar grooves 16 formed from the lower side of the elements 10. The position of the assembly grooves and the dimensions of the profiles are such that the polystyrene layer 11 is substantially adjacent to the wall 2. The elements 10 are arranged in staggered rows, the elements of one stage being offset laterally by half a step with respect to those of the neighboring stages. This provision is also optional.

Dans leur partie située entre le mur 1 et l'aile extérieure 5 des profilés 2, le bord supérieur et le bord inférieur des éléments 10 s'étendent horizontalement et s'appliquent sur les faces horizontales, respectivement supérieure et inférieure, de l'âme 3 de ces profilés. En revanche, entre l'aile 5 et la face avant 22 de la couche d'isolant 11, ce bord inférieur 23 et ce bord supérieur 24 sont inclinés et vont en descendant depuis l'aile 5 vers l'extérieur. Dans cette région les bords respectivement supérieur et inférieur de deux éléments superposés 10-1 et 10-2 forment entre eux un intervalle étroit 25, localement élargi par une rainure 26 ménagée dans le bord inférieur 23 de l'élément supérieur 10-1, selon une direction longitudinale horizontale et perpendiculaire au mur. L'eau de pluie qui peut pénétrer, sous la pression du vent, dans l'intervalle 25, se dépose dans la chambre de décompression 27 formée par la rainure 26 et retourne vers l'extérieur en descendant le long de l'intervalle 25, sans pouvoir pénétrer au-delà de la chambre 27 en raison de l'inclinaison des bords 23 et 24.In their part located between the wall 1 and the outer wing 5 of the profiles 2, the upper edge and the lower edge of the elements 10 extend horizontally and are applied to the horizontal faces, respectively upper and lower, of the core 3 of these profiles. On the other hand, between the wing 5 and the front face 22 of the insulating layer 11, this lower edge 23 and this upper edge 24 are inclined and go down from the wing 5 towards the outside. In this region the respectively upper and lower edges of two superimposed elements 10-1 and 10-2 form between them a narrow gap 25, locally enlarged by a groove 26 formed in the lower edge 23 of the upper element 10-1, according to a longitudinal direction horizontal and perpendicular to the wall. The rainwater which can penetrate, under the pressure of the wind, into the interval 25, is deposited in the decompression chamber 27 formed by the groove 26 and returns towards the outside while descending along the interval 25, without being able to penetrate beyond the room 27 due to the inclination of edges 23 and 24.

Des rainures 20 sont ménagées dans l'épaisseur de la couche d'isolant 11, à partir de la face externe 22 de celle-ci. Ces rainures ont une largeur et une profondeur de quelques millimètres. Elles s'étendent verticalement et sont régulièrement espacées les unes des autres dans la direction de la largeur des éléments 10, donc du mur 1. Les rainures 20 permettent l'écoulement vers le bas de l'eau liquide produite par la condensation, au contact de la paroi froide constituée par le parement 12, de la vapeur diffusant depuis l'intérieur du bâtiment à travers le mur 1 et la couche d'isolant 11. Dans les éléments de vêture connus, comme montré à la figure 2, les rainures 20 débouchent dans le bord inférieur 23 et dans le bord supérieur 24 des couches d'isolant. Il en résulte que l'eau de pluie qui pénètre, sous la pression du vent, entre les parements de deux éléments superposés 10-1 et 10-2 et dans l'intervalle 25 séparant les couches d'isolant peut s'introduire dans les rainures 20 de l'élément inférieur 10-2, soit directement, soit en redescendant le long du bord 24 après s'être déposée dans la chambre de décompression 27. Cette pénétration de l'eau est favorisée par le fait que la face externe 22 de la couche d'isolant 11 des éléments de vêture s'étend au-delà du parement 12 vers le haut et vers le bas, l'intervalle entre les parements de deux éléments superposés étant ainsi plus large que l'intervalle 25 entre les couches d'isolant.Grooves 20 are formed in the thickness of the insulating layer 11, starting from the external face 22 thereof. These grooves have a width and a depth of a few millimeters. They extend vertically and are regularly spaced from each other in the direction of the width of the elements 10, therefore of the wall 1. The grooves 20 allow the downward flow of the liquid water produced by the condensation, in contact of the cold wall formed by the facing 12, of the vapor diffusing from inside the building through the wall 1 and the layer of insulation 11. In the known cladding elements, as shown in FIG. 2, the grooves 20 open into the lower edge 23 and into the upper edge 24 of the insulation layers. As a result, rainwater which penetrates, under the pressure of the wind, between the facings of two superimposed elements 10-1 and 10-2 and in the interval 25 separating the layers of insulation can be introduced into the grooves 20 of the lower element 10-2, either directly or by descending along the edge 24 after being deposited in the decompression chamber 27. This penetration of water is favored by the fact that the external face 22 of the insulating layer 11 of the covering elements extends beyond the facing 12 upwards and downwards, the interval between the facingings of two superimposed elements thus being wider than the interval 25 between the layers insulation.

Aux figures 3 et 4, relatives à un élément de vêture selon l'invention, les mêmes signes de référence qu'aux figures 1 et 2 sont utilisés pour désigner des parties semblables. Cet élément 110 diffère des éléments 10-1 et 10-2 illustrés à la figure 2 en ce que les rainures 20 de profondeur uniforme, débouchant aux bords supérieur et inférieur de la couche d'isolant, sont remplacées par des rainures 120 dont la profondeur décroît progressivement depuis le bord inférieur 23 pour s'annuler à une certaine distance d du bord supérieur 24. Dans l'exemple illustré cette distance d est d'environ 20 mm, la hauteur de l'élément 110 étant d'environ 400 mm.In Figures 3 and 4, relating to a cladding element according to the invention, the same reference signs as in Figures 1 and 2 are used to designate similar parts. This element 110 differs from elements 10-1 and 10-2 illustrated in FIG. 2 in that the grooves 20 of uniform depth, opening at the upper and lower edges of the layer of insulation, are replaced by grooves 120 whose depth gradually decreases from the bottom edge 23 to cancel at a certain distance d from the upper edge 24. In the example illustrated, this distance d is approximately 20 mm, the height of the element 110 being approximately 400 mm.

Les rainures 120 ne débouchant pas dans le bord supérieur des éléments de vêture, l'eau de pluie ne peut s'y introduire pour s'écouler vers le bas.Since the grooves 120 do not open into the upper edge of the covering elements, rainwater cannot be introduced therein to flow downwards.

Les rainures 120 peuvent être réalisées de façon connue au moyen d'un fil chaud, leur profondeur variant de façon linéaire d'une extrémité à l'autre. Elles pourraient également être réalisées par usinage. Dans ce cas leur profondeur pourrait suivre une loi différente. Elle pourrait par exemple être sensiblement constante sur une partie substantielle au moins de la hauteur des rainures et s'annuler brusquement à la distance d du bord supérieur, ou décroître sur une faible hauteur au voisinage de l'extrémité supérieure des rainures.The grooves 120 can be produced in a known manner by means of a hot wire, their depth varying linearly from one end to the other. They could also be produced by machining. In this case their depth could follow a different law. It could for example be substantially constant over at least a substantial part of the height of the grooves and abruptly cancel out at the distance d from the upper edge, or decrease over a small height in the vicinity of the upper end of the grooves.

La largeur, la profondeur et l'écartement mutuel des rainures 120 sont choisis de façon à ne pas retenir l'eau par capillarité sur une fraction notable de la hauteur et à absorber le débit d'eau maximal susceptible d'être produit dans des conditions normales, compte tenu des caractéristiques climatiques de la région dans laquelle la vêture est utilisée. A titre d'exemple, une largeur des rainures de 5 mm environ, une profondeur variant linéairement de 10 mm environ à 0 et un pas latéral de 20 mm environ conviennent sur le territoire de la France métropolitaine.The width, the depth and the mutual spacing of the grooves 120 are chosen so as not to retain water by capillarity over a significant fraction of the height and to absorb the maximum water flow rate capable of being produced under conditions normal, taking into account the climatic characteristics of the region in which the clothing is used. By way of example, a width of the grooves of approximately 5 mm, a depth varying linearly from approximately 10 mm to 0 and a lateral pitch of approximately 20 mm are suitable in the territory of metropolitan France.

Claims (6)

1. Cladding element (110) intended to be applied over the external surface of a wall (1) of a building, exhibiting an upper edge (24) and a lower edge (23) and comprising a thermally insulating layer (11) and a facing (12) adhering to the external face (22) of the latter, channels (120) oriented from the top downwards being provided between the insulating layer and the facing and of sufficient length in order to permit the escape of water produced by condensation of vapour diffusing from within the building, characterised in that the said channels (120) emerge only into the lower edge (23) of the element.
2. Cladding element according to Claim 1, characterised in that the channels are formed by grooves (120) made in the external face (22) of the insulating layer (11).
3. Cladding element according to either of Claims 1 and 2, characterised in that the channels have a depth, in the direction perpendicular to the surface of the wall, which decreases progressively from the lower edge (23) in order to become zero at a certain distance (d) from the upper edge (24).
4. Cladding element according to Claim 3, characterised in that the depth varies substantially linearly from one end of the channels to the other.
5. Cladding element according to either of Claims 1 and 2, characterised in that the depth of the channels is substantially constant over an appreciable portion, at least, of their height.
6. Cladding element according to one of the preceding claims, characterised in that the external face (22) of the insulating layer extends beyond the facing (12) upwardly at the upper edge (24) and/or downwardly at the lower edge (23).
