Description

L'invention concerne des panneaux préfabriqués pour le revêtement de parois, notamment de bâtiments. Elle s'étend aussi à un procédé de mise en oeuvre de ceux-ci en vue de revêtir des parois de bâtiments.The invention relates to prefabricated panels for coating walls, in particular buildings. It also extends to a process for implementing them with a view to coating the walls of buildings.

Dans le but d'accroître le coefficient d'isolation des bâtiments, il est devenu classique de disposer, du côté extérieur, des plaques d'isolant qui sont fixées sur les parois par différents moyens; ces plaques d'isolation externes présentent l'avantage d'augmenter considérablement l'inertie thermique des bâtiments et leurs qualités de confort. Ces plaques d'isolant doivent être habillées en vue de les protéger et de conférer au bâtiment un aspect esthétique satisfaisant. Un procédé consiste à projeter un enduit sur la face externe des plaques après leur mise en place. Toutefois, la mise en oeuvre d'un tel procédé est onéreuse et requiert une main-d'oeuvre importante. En outre, l'expérience a montré que les enduits ainsi mis en place vieillissent très rapidement en raison des dilatations différentielles qui, s'exerçant sur de grandes surfaces, provoquent des décollements locaux de l'enduit avec apparition de cloques, boursouflures ou autres défauts de surface. En outre, de tels enduits de surface granuleuse ont tendance à accrocher les poussières et demandent un entretien régulier.With the aim of increasing the insulation coefficient of buildings, it has become conventional to have, on the outside, insulating plates which are fixed to the walls by different means; these external insulation plates have the advantage of considerably increasing the thermal inertia of the buildings and their comfort qualities. These insulation sheets must be dressed to protect them and give the building a satisfactory aesthetic appearance. One method consists in spraying a coating on the external face of the plates after their installation. However, the implementation of such a method is expensive and requires a large workforce. In addition, experience has shown that the plasters thus put in place age very quickly due to differential expansions which, acting on large surfaces, cause local detachments of the plaster with the appearance of blisters, blisters or other defects. of surface. In addition, such grainy surface plasters tend to catch dust and require regular maintenance.

Pour tenter de remédier aux défauts précités, ont été conçus des systèmes de bardage rapporté, consistant à mettre en place contre la paroi à revêtir, une ossature d'accrochage qui permet de fixer d'abord l'isolant thermique, puis des dalles de revêtement extérieur; par exemple dans l'avis technique du CSTB no. 7/82-198, il est décrit un bardage de ce type dans lequel l'ossature comprend des chevrons et lisses maintenus par des pattes scellées dans la paroi, l'isolation thermique étant constituée par une couche de laine de verre et les dalles de revêtement extérieur par des plaques de pierres reconstituées. Toutefois, un tel système est relativement complexe et exige une main d'oeuvre importante sur chantier pour assembler les divers éléments.In an attempt to remedy the aforementioned faults, additional cladding systems have been designed, consisting of putting in place against the wall to be coated, a fastening frame which makes it possible to fix the thermal insulation first, then the covering slabs. outside; for example in the CSTB technical opinion no. 7 / 82-198, a cladding of this type is described in which the framework comprises rafters and beams held by tabs sealed in the wall, the thermal insulation consisting of a layer of glass wool and the slabs of exterior cladding with reconstructed stone slabs. However, such a system is relatively complex and requires a large workforce on site to assemble the various elements.

Une autre solution décrite dans la demande de brevet FR no. 81.16386 publiée sous le no. 2 512 094 consiste à réaliser en usine des panneaux préfabriqués de revêtement, constitués par un complexe isolant/peau extérieure, directement applicable sur la paroi à revêtir. Dans la demande de brevet sus-évoquée, ces panneaux comprennent une plaque de matière isolante, sur une face de laquelle a été collée une feuille de matière plastique; en bordure de la plaque isolante, la feuille de matière plastique est conformée pour permettre d'assurer une fixation non apparente du panneau sur la paroi à revêtir.Another solution described in patent application FR no. 81.16386 published under no. 2,512,094 consists of making prefabricated cladding panels in the factory, consisting of an insulating / outer skin complex, directly applicable on the wall to be clad. In the abovementioned patent application, these panels comprise a plate of insulating material, on one face of which a sheet of plastic material has been stuck; at the edge of the insulating plate, the plastic sheet is shaped to allow an invisible fixing of the panel on the wall to be coated.

De tels panneaux bénéficient d'une pose beaucoup plus simple et rapide que les bardages sus-évoqués, surtout si l'on utilise des panneaux de surfaces importantes (ce qui permet d'en réduire le nombre et, donc, de diminuer les temps de pose). Toutefois, l'apparence esthétique non traditionnelle des parois revêtues de tels panneaux est peu satisfaisante et rappelle celle des constructions de type préfabriqué, qui sont peu pri- . sées par les utilisateurs. Ce défaut très grave dans ce secteur technique limite considérablement le développement de ce type de technique utilisant des panneaux préfabriqués et, jusqu'à présent, il n'a pas été trouvé de solution satisfaisante permettant aux panneaux préfabriqués de bénéficier à la fois, d'un coût réduit, d'une mise en oeuvre simple et rapide et, une fois installés, d'une esthétique traditionnelle (faisant disparaître toute idée de préfabrication).Such panels benefit from a much simpler and faster installation than the above-mentioned cladding, especially if panels of large surfaces are used (which makes it possible to reduce the number and, therefore, to decrease the times of pose). However, the non-traditional aesthetic appearance of the walls coated with such panels is unsatisfactory and recalls that of constructions of the prefabricated type, which are not very practical. users. This very serious defect in this technical sector considerably limits the development of this type of technique using prefabricated panels and, until now, a satisfactory solution has not been found allowing prefabricated panels to benefit from both a reduced cost, of a simple and fast implementation and, once installed, of a traditional esthetics (making disappear any idea of prefabrication).

Par ailleurs, le brevet US no. 4 299 069 décrit un procédé de fabrication d'un panneau, consistant à positionner au fond d'un moule des briquettes écartées les unes des autres, à distribuer du mortier dans les espaces entre briquettes, à couvrir la couche ainsi constituée au moyen d'une nappe de fibre, puis à couler sur l'ensemble du polyuréthane, de façon à obtenir après polymérisation une couche de mousse expansée. Une telle fabrication présente le défaut d'être complexe et onéreuse et d'exiger l'exécution d'opérations demandant des compétences différentes (préparation et mise en place du mortier, réalisation de la mousse expansée). De plus, les panneaux doivent nécessairement être équipés d'éléments rapportés en tôle pour les fixer ensuite contre le mur à revêtir.Furthermore, US patent no. 4,299,069 describes a method of manufacturing a panel, consisting of positioning briquettes spaced apart from one another at the bottom of a mold, of distributing mortar in the spaces between briquettes, of covering the layer thus formed by means of a sheet of fiber, then to flow over all of the polyurethane, so as to obtain, after polymerization, a layer of expanded foam. Such manufacture has the defect of being complex and expensive and of requiring the execution of operations requiring different skills (preparation and installation of the mortar, production of the expanded foam). In addition, the panels must necessarily be fitted with sheet metal inserts to then fix them against the wall to be coated.

Par ailleurs, les brevets DE-A-2 552 134 FR-A-2 328 814 ainsi que le brevet CH-A-524 021 qui décrit notamment les caractéristiques a, b et c de la revendication 1 décrivent des techniques d'habillage sur chantier de murs, consistant en particulier à combiner une couche d'isolation et des plaques de protection externes, les plaques de protection étant notamment fixées à la couche d'isolation par des éléments en saillie pénétrant dans des éléments conjugués en creux. Toutefois, ces techniques ne permettent pas d'associer toutes les qualités suivantes, recherchées par l'invention:

  • conditionner une mise en oeuvre facile et rapide sur chantier,
  • présenter une structure simple conduisant à une fabrication en usine de coût réduit,
  • une fois en place, conférer une grande inertie thermique et un bon confort au bâtiment grâce à l'isolation thermique externe dont celui-ci se trouve doté,
  • assurer une protection efficace de l'isolant thermique placé vers l'extérieur,
  • bénéficier d'une bonne tenue mécanique,
  • conférer aux parois revêtues un aspect traditionnel bénéficiant d'une esthétique attrayante.
Furthermore, the patents DE-A-2 552 134 FR-A-2 328 814 as well as the patent CH-A-524 021 which describes in particular the characteristics a, b and c of claim 1 describe dressing techniques on construction of walls, consisting in particular of combining an insulation layer and external protection plates, the protection plates being in particular fixed to the insulation layer by projecting elements penetrating into conjugate hollow elements. However, these techniques do not make it possible to combine all of the following qualities sought by the invention:
  • condition an easy and fast implementation on site,
  • present a simple structure leading to factory production at reduced cost,
  • once in place, impart great thermal inertia and good comfort to the building thanks to the external thermal insulation with which it is provided,
  • provide effective protection of the thermal insulation placed outside,
  • benefit from good mechanical strength,
  • give the coated walls a traditional appearance with an attractive aesthetic.

En particulier, les techniques antérieures sus- évoquées sont mises en oeuvre sur chantier et ne résolvent pas, dans le cas de panneaux préfabriqués, le problème consistant à fixer ceux-ci de façon simple et peu coûteuse contre la paroi à revêtir, tout en préservant l'aspect strictement traditionnel de la paroi obtenue.In particular, the above-mentioned prior techniques are implemented on site and do not solve, in the case of prefabricated panels, the problem of fixing them in a simple and inexpensive manner against the wall to be coated, while preserving the strictly traditional aspect of the wall obtained.

La présente invention se propose de fournir une solution au problème du revêtement des parois de bâtiments (ou autre), qui soit exempte des défauts sus-évoqués des solutions connues et qui combine les qualités ci-dessus citées.The present invention proposes to provide a solution to the problem of coating the walls. of buildings (or other), which is free from the aforementioned defects of known solutions and which combines the qualities mentioned above.

A cet effet, le panneau préfabriqué de revêtement conforme à l'invention comprend en combinaison les moyens et caractéristiques suivantes:

  • (a) une plaque en un matériau isolant sur le plan thermique, notamment polystyrène de densité élevée,
  • (b) une pluralité de plaquettes rigides, notamment en terre cuite, d'un format plus petit, assujetties sur une des faces de la plaque isolante,
  • (c) un becquet de recouvrement prévu sur un bord de chaque plaquette et une forme conjuguée dudit becquet prévue sur le bord opposé,
  • (d) la plaque isolante comportant plusieurs rainures d'accrochage préalablement ménagées en creux directement dans le matériau isolant de ladite plaque de façon à déboucher sur sa face,
  • (e) lesdites rainures d'accrochage s'étendant le long de lignes parallèles courant d'un bout à l'autre de la plaque isolante et séparées entre elles d'une distance correspondant à la hauteur d'une plaquette réduite de son becquet de recouvrement,
  • (f) chaque plaquette comportant, sur une face, une barrette continue d'accrochage s'étendant sur toute sa largeur et de section adaptée pour pouvoir pénétrer en force dans une rainure d'accrochage de la plaque par le jeu de l'élasticité du matériau isolant,
  • (g) chaque plaquette comportant sur sa face, des portions d'appui situées de part et d'autre de la barrette d'accrochage, lesdites portions d'appui étant agencées pour venir en appui contre la plaque isolante lorsque la barrette d'accrochage de la plaquette est enfoncée dans une rainure d'accrochage de ladite plaque isolante,
  • (h) les plaquettes étant disposées en position contiguë les unes des autres avec, d'une part, le becquet de recouvrement d'une plaquette en contact avec le bord de forme conjuguée de la plaquette inférieure, d'autre part, le chant latéral d'une plaquette accolée au chant latéral de la plaquette voisine,
  • (i) des zones de réservations dépourvues de plaquettes étant préservées sur la plaque en vue de la fixation du panneau préfabriqué sur la paroi à revêtir.
To this end, the prefabricated covering panel according to the invention comprises in combination the following means and characteristics:
  • (a) a plate made of a thermally insulating material, in particular high density polystyrene,
  • (b) a plurality of rigid plates, in particular terracotta, of a smaller size, secured on one of the faces of the insulating plate,
  • (c) a covering spoiler provided on one edge of each plate and a conjugate shape of said spoiler provided on the opposite edge,
  • (d) the insulating plate comprising several hooking grooves previously formed in a hollow directly in the insulating material of said plate so as to open onto its face,
  • (e) said attachment grooves extending along parallel lines running from one end to the other of the insulating plate and separated from each other by a distance corresponding to the height of a reduced plate from its spoiler. recovery,
  • (f) each plate comprising, on one face, a continuous latching bar extending over its entire width and of cross section adapted to be able to penetrate in force into a latching groove of the plate by the play of the elasticity of the insulating material,
  • (g) each plate comprising, on its face, support portions situated on either side of the attachment bar, said support portions being arranged to come into abutment against the insulating plate when the attachment bar the plate is pressed into a hooking groove of said insulating plate,
  • (h) the plates being arranged in contiguous position with one another with, on the one hand, the spoiler for covering a plate in contact with the mating edge of the lower plate, on the other hand, the lateral edge a plate attached to the side edge of the neighboring plate,
  • (i) reservation zones devoid of plates being preserved on the plate for the purpose of fixing the prefabricated panel to the wall to be coated.

De façon classique, la plaque isolante peut être de forme générale rectangulaire, les plaquettes en terre cuite, elles-mêmes de forme générale rectangulaire étant disposées en positions contiguës suivant plusieurs lignes parallèles à deux des côtés de la plaque isolante. Les plaquettes d'une même ligne sont accolées les unes aux autres, en particulier par des chants plats perpendiculaires à la direction des lignes, cependant que les plaquettes d'une ligne donnée coopèrent avec les plaquettes des lignes contiguës de façon à se recouvrir sur une faible hauteur.Conventionally, the insulating plate may be of generally rectangular shape, the terracotta plates, themselves of generally rectangular shape, being arranged in contiguous positions along several lines parallel to two of the sides of the insulating plate. The plates of the same line are joined to each other, in particular by flat edges perpendicular to the direction of the lines, while the plates of a given line cooperate with the plates of the contiguous lines so as to overlap on a low height.

Les plaquettes accrochées par leur barrette contre la plaque isolante sont avantageusement collées contre celle-ci pour assurer leur fixation définitive.The plates hung by their bar against the insulating plate are advantageously glued against the latter to ensure their final fixing.

Selon une autre caractéristique de l'invention, la plaque isolante de forme rectangulaire possède sur deux chants contigus, des structures d'emboîtement mâles et sur les deux autres chants, des structures d'emboîtement femelles conjuguées.According to another characteristic of the invention, the insulating plate of rectangular shape has on two contiguous edges, male interlocking structures and on the other two edges, conjugated female interlocking structures.

Conformément à un mode de réalisation préféré, le panneau de revêtement présente, en combinaison, les caractéristiques suivantes:

  • la longueur de la plaque isolante est adaptée pour correspondre à un nombre entier de plaquettes sur une ligne,
  • les plaquettes d'une ligne sont appareillées en positions croisées par rapport aux plaquettes des lignes contiguës,
  • les plaquettes d'une ligne sur deux sont disposées de façon à couvrir entièrement la longueur de la plaque isolante, sans partie apparente,
  • les zones de réservations dépourvues de plaquette sont préservées aux extrémités des autres lignes, chaque réservation correspondant à la surface d'une demi-plaquette.
According to a preferred embodiment, the covering panel has, in combination, the following characteristics:
  • the length of the insulating plate is adapted to correspond to an integer number of plates on a line,
  • the pads of a line are fitted in crossed positions relative to the pads of the adjoining lines,
  • the inserts of every second line are arranged so as to completely cover the length of the insulating plate, with no visible part,
  • the reservation zones devoid of wafers are preserved at the ends of the other lines, each reservation corresponding to the surface of a half wafer.

Le panneau conforme à l'invention est préfabriqué en usine à un coût réduit, par des opérations simples, consistant entre autres:

  • à réaliser des plaquettes en terre cuite, pourvues sur une face de moyens d'accrochage en saillie,
  • à réaliser une plaque en un matériau isolant, de surface correspondant à celle d'une pluralité de plaquettes et pourvue sur une face de plusieurs rainures agencées le long de lignes parallèles de façon à permettre l'accrochage des plaquettes en positions contiguës par introduction en force de leurs moyens d'accrochage dans lesdites rainures,
  • après encollage de la surface de la plaque isolante et/ou des plaquettes, à appliquer chaque plaquette contre la plaque isolante en introduisant ses moyens d'accrochage dans une rainure de la plaque,
  • et à poursuivre l'opération précitée pour les autres plaquettes, les plaquettes d'une même ligne étant accolées par leurs chants latéraux, cependant que les plaquettes de deux lignes contiguës sont amenées à se recouvrir partiellement.
The panel according to the invention is prefabricated in the factory at a reduced cost, by simple operations, consisting inter alia:
  • to produce terracotta plates, provided on one side with projecting hooking means,
  • producing a plate of insulating material, with a surface corresponding to that of a plurality of plates and provided on one face with several grooves arranged along parallel lines so as to allow the plates to be hooked in contiguous positions by force introduction their attachment means in said grooves,
  • after gluing of the surface of the insulating plate and / or of the plates, applying each plate against the insulating plate by introducing its hooking means into a groove in the plate,
  • and to continue the above operation for the other plates, the plates of the same line being joined by their lateral edges, while the plates of two contiguous lines are caused to overlap partially.

Il est à noter que le positionnement et l'alignement des plaquettes sur la surface de la plaque isolante s'effectuent sans gabarit, simplement en logeant les moyens d'accrochage de celles-ci dans les rainures de la plaque. De plus, pendant la prise de la colle, les plaquettes sont maintenues par leurs moyens d'accrochage sans qu'il soit nécessaire de prévoir des appareils de pressage.It should be noted that the positioning and alignment of the plates on the surface of the insulating plate is effected without a template, simply by accommodating the means for hooking them in the grooves of the plate. In addition, during the setting of the glue, the plates are held by their hooking means without the need to provide pressing devices.

La mise en oeuvre sur chantier du panneau préfabriqué conforme à l'invention se réduit à des opérations simples et peu nombreuses, n'exigeant qu'une main d'oeuvre réduite. Elle consiste:

  • à appliquer un panneau contre la paroi,
  • à fixer ledit panneau sur ladite paroi au moyen d'organes de fixation mis en place au niveau de réservations dépourvues de plaquette,
  • à appliquer un autre panneau contre la paroi en position contiguë au premier en amenant les structures d'emboîtement desdits panneaux à coopérer,
  • à fixer ledit panneau comme précédemment et à poursuivre les opérations précédentes jusqu'à couvrir la paroi à revêtir,
  • et à mettre en place des plaquettes complémentaires au niveau des réservations des panneaux, par encollage et introduction de leurs moyens d'accrochage dans les rainures des plaques d'isolation.
The implementation on site of the prefabricated panel according to the invention is reduced to simple and few operations, requiring only a reduced workforce. It consists:
  • to apply a panel against the wall,
  • fixing said panel to said wall by means of fixing members placed at the level of reservations without a plate,
  • to apply another panel against the wall in a position contiguous to the first by bringing the interlocking structures of said panels to cooperate,
  • fixing said panel as before and continuing the previous operations until covering the wall to be coated,
  • and to set up additional plates at the level of the reservations of the panels, by gluing and introduction of their attachment means in the grooves of the insulation plates.

On obtient ainsi une paroi où les jonctions entre panneaux ne sont plus apparentes et qui possède l'aspect traditionnel et très recherché d'une paroi en terre cuite.A wall is thus obtained in which the junctions between panels are no longer apparent and which has the traditional and highly sought-after appearance of a terracotta wall.

Le panneau de revêtement représenté à titre d'exemple aux figures 4 et 5 est réalisé en usine à partir d'une plaque d'isolation 1 telle que représentée aux figures 1 et 2 et d'une pluralité de plaquettes en terre cuite 3, telles que celle représentée à la figure 3.The covering panel shown by way of example in FIGS. 4 and 5 is produced in the factory from an insulation plate 1 as shown in FIGS. 1 and 2 and from a plurality of terracotta plates 3, such as than that shown in Figure 3.

La plaque 1 est réalisée en mousse de polystyrène de densité élevée, présentant en particulier -une masse volumique sèche comprise entre 35 et 40 kg/cm3. Cette plaque peut notamment être fabriquée à partir de plaques de polystyrène extrudé, par découpage et usinage. Bien entendu, il est également possible de fabriquer la plaque 1 par un procédé de moulage traditionnel.The plate 1 is made of high density polystyrene foam, having in particular -a dry density between 35 and 40 kg / cm 3 . This plate can in particular be manufactured from extruded polystyrene plates, by cutting and machining. Of course, it is also possible to manufacture the plate 1 by a traditional molding process.

A titre indicatif, la plaque 1 en forme générale de parallélépipède rectangle peut posséder les dimensions suivantes: épaisseur 5 cm, hauteur 60 cm, longueur 120 cm, surface couverte 0,72 m2.As an indication, the plate 1 in the general shape of a rectangular parallelepiped can have the following dimensions: thickness 5 cm, height 60 cm, length 120 cm, covered area 0.72 m 2 .

Le long de deux chants contigus, la plaque 1 est dotée de nervures d'emboîtement 4 et 5, cependant que le long des deux autres chants, elle est dotée de rainures conjuguées 6 et 7.Along two contiguous edges, the plate 1 is provided with interlocking ribs 4 and 5, while along the other two edges, it is provided with conjugated grooves 6 and 7.

De plus, sur une face la de la plaque 1, sont ménagées plusieurs rainures parallèles telles que 8; ces rainures équidistantes s'étendent parallèlement à la longueur de la plaque et sont en l'exemple au nombre de huit.In addition, on one side of the plate 1, are formed several parallel grooves such as 8; these equidistant grooves extend parallel to the length of the plate and are in the example eight in number.

Par ailleurs, les plaquettes en terre cuite 3 de forme générale rectangulaire présentent chacune des dimensions appropriées pour permettre de couvrir la plaque 1 avec un nombre entier de plaquettes (notamment de l'ordre d'une trentaine). Par exemple, les plaquettes ont une longueur égale au quart de celle de la plaque 1 et une hauteur égale au huitième de la hauteur de ladite plaque (la partie de recouvrement de chaque plaquette n'étant pas prise en compte dans cette hauteur).Furthermore, the terracotta plates 3 of generally rectangular shape each have suitable dimensions to allow the plate 1 to be covered with a whole number of plates (in particular of the order of thirty). For example, the plates have a length equal to a quarter of that of the plate 1 and a height equal to one-eighth of the height of said plate (the covering part of each plate not being taken into account in this height).

Chaque plaquette 3 comporte, sur une face 3a, une barrette 9 en saillie, qui s'étend parallèlement à sa plus grande dimension. En l'exemple, cette barrette 9 possède une tête élargie en forme de secteur de cercle, adaptée pour s'insérer en force dans une des rainures 8 de la plaque d'isolation 1.Each plate 3 comprises, on one face 3a, a protruding bar 9, which extends parallel to its largest dimension. In the example, this bar 9 has an enlarged head in the form of a sector of a circle, adapted to be inserted by force into one of the grooves 8 of the insulation plate 1.

En outre, la face 3a de la plaquette possède une portion en retrait 3b, s'étendant au voisinage de son axe médian, en vue de permettre une ventilation dans le panneàu fini.In addition, the face 3a of the wafer has a recessed portion 3b, extending in the vicinity of its median axis, in order to allow ventilation in the purlin at the end.

Le long d'un bord longitudinal, la plaquette comporte un becquet de recouvrement 10 présentant une forme trapézoïdale en déport comme l'illustre la figure 3 et les figures 5 et 6.Along a longitudinal edge, the plate has a covering spoiler 10 having an offset trapezoidal shape as illustrated in FIG. 3 and in FIGS. 5 and 6.

L'autre bord longitudinal 11 de la plaquette présente une forme trapézoïdale conjuguée de celle du becquet 10, de façon à pouvoir s'insérer sous ledit becquet lors de la coopération de deux plaquettes.The other longitudinal edge 11 of the plate has a trapezoidal shape combined with that of the spoiler 10, so that it can be inserted under said spoiler during the cooperation of two plates.

Au voisinage du bord 11, la face 3c de la plaquette (face appelée à être apparente) est dotée d'une échancrure 12, destinée à former une feuillure apparente à la jonction des plaquettes. Au-delà de l'échancrure 11, la face 3c est plane jusqu'à l'extrémité du becquet de recouvrement . 10, l'épiderme de cette face pouvant être lisse, sablé ou arraché.In the vicinity of the edge 11, the face 3c of the wafer (face called to be visible) is provided with a notch 12, intended to form an apparent rebate at the junction of the wafers. Beyond the notch 11, the face 3c is flat up to the end of the covering spoiler. 10, the epidermis of this face being able to be smooth, sanded or torn off.

De plus, les chants latéraux 3d de la plaquette sont plats.In addition, the 3d side edges of the insert are flat.

Les plaquettes 3 sont fabricables en terre cuite par extrusion, de façon traditionnelle (ou également le cas échéant par pressage).The plates 3 can be made of terracotta by extrusion, in the traditional way (or also if necessary by pressing).

Le panneau de revêtement conforme à l'invention est fabriqué en usine à partir d'une plaque d'isolation 1 et d'une pluralité de plaquettes 3 (28 en l'exemple représenté à la figure 4).The covering panel according to the invention is manufactured in the factory from an insulation plate 1 and from a plurality of plates 3 (28 in the example shown in FIG. 4).

Ce panneau est réalisé en disposant des cordons de colle 13 sur sa face la et en appliquant les plaquettes contre cette face avec introduction des barrettes 9 dans les rainures 8. Les plaquettes d'une ligne L sont appareillées en positions croisées par rapport aux plaquettes des lignes contiguës L'. Sur une ligne sur deux (L), les plaquettes sont disposées de façon à couvrir toute la longueur de la plaque 1, tandis que sur les autres lignes (L'), elles sont décalées et préservent aux extrémités desdites lignes des réservations R dépourvues de plaquette. A l'exception de ces réservations (chacune de surface correspondant à celle d'une demi-plaquette), la totalité de la plaque 1 est couverte de plaquettes 3.This panel is produced by placing beads of glue 13 on its face 1a and applying the plates against this face with introduction of the bars 9 in the grooves 8. The plates of a line L are fitted in crossed positions relative to the plates of the The adjoining lines. On one line out of two (L), the plates are arranged so as to cover the entire length of the plate 1, while on the other lines (L '), they are offset and preserve at the ends of said lines reservations R devoid of brochure. With the exception of these reservations (each of area corresponding to that of a half-plate), the entire plate 1 is covered with plates 3.

Les plaquettes d'une même ligne sont accolées entre elles par leurs chants latéraux plats 3d, cependant que les plaquettes d'une ligne ont leur becquet 10 qui sont orientés vers le bas et viennent recouvrir les bords conjugués 11 des plaquettes de la ligne du dessous, les échancrures 12 formant des feuillures F entre les lignes.The plates of the same line are joined together by their flat 3d side edges, while the plates of a line have their spoiler 10 which are oriented downwards and come to cover the conjugate edges 11 of the plates of the line below, the notches 12 forming rabbets F between the lines.

Comme l'illustre la figure 5, les plaquettes d'une des lignes extrêmes (Li) (qui sera placée en partie basse lors de la pose du panneau) sont positionnées de sorte que leur becquet de recouvrement 10 déborde par rapport au chant correspondant de la plaque 1, cependant que les plaquettes de la ligne extrême opposée (Ls) (ligne supérieure) sont disposées de sorte que leur bord 11 affleure le chant correspondant de ladite plaque.As illustrated in FIG. 5, the plates of one of the extreme lines (Li) (which will be placed in the lower part when the panel is installed) are positioned so that their covering spoiler 10 projects beyond the corresponding edge of the plate 1, while the plates of the opposite extreme line (Ls) (upper line) are arranged so that their edge 11 is flush with the corresponding edge of said plate.

Les panneaux de revêtement ainsi préfabriqués en usine sont destinés à revêtir des parois murales, notamment de bâtiments.The cladding panels thus prefabricated in the factory are intended to clad wall walls, in particular of buildings.

Comme l'illustre la figure 6, la mise en place de ces panneaux consiste à appliquer ces panneaux contre la paroi M de sorte que leurs nervures (4, 5) et rainures (6, 7) d'emboîtement coopèrent et que les plaquettes des lignes extrêmes (Li, Ls) se recouvrent par leurs becquet et bord conjugués.As illustrated in FIG. 6, the positioning of these panels consists in applying these panels against the wall M so that their interlocking ribs (4, 5) and grooves (6, 7) cooperate and the plates of the extreme lines (Li, Ls) overlap with their combined spoiler and edge.

Chaque panneau est fixé sur la paroi au moyen de quatre chevilles à tête plate, telles que 14, disposées dans les quatre réservations d'angle R du panneau. De façon classique, les plaques 1 peuvent en outre être collées sur la paroi murale.Each panel is fixed to the wall by means of four flat-headed dowels, such as 14, arranged in the four corner reservations R of the panel. Conventionally, the plates 1 can also be glued to the wall.

L'habillage est ensuite terminé en disposant entre les panneaux dans toutes les réservations R des plaquettes complémentaires 3', identiques aux plaquettes 3. Ces plaquettes 3' sont collées comme précédemment, avec introduction de leur barrette dans les rainures des plaques 1, barrettes qui assurent leur maintient pendant la prise de la colle.The covering is then finished by placing between the panels in all the reservations R additional plates 3 ', identical to the plates 3. These plates 3' are glued as before, with introduction of their bar into the grooves of the plates 1, bars which ensure their maintenance during the setting of the glue.

On obtient ainsi une paroi d'aspect traditionnel où les jonctions entre panneaux disparaissent entièrement et où seules les plaquettes en terre cuite restent apparentes.This gives a wall of traditional appearance where the junctions between panels disappear entirely and where only the terracotta plates remain visible.

Les recouvrements entre plaquettes 3 assurent une bonne étanchéité à l'eau, cependant que les emboîtements des plaques d'isolation 1 évitent les fuites thermiques.The overlaps between plates 3 ensure good water tightness, while the interlocking of the insulation plates 1 prevent thermal leaks.

De plus, les portions en retrait 3b des plaquettes ménagent entre celles-ci et les plaques d'isolation des interstices de ventilation permettant l'élimination des traces d'humidité sur la surface des plaques.In addition, the recessed portions 3b of the plates provide between them and the insulation plates of the ventilation gaps allowing the elimination of traces of moisture on the surface of the plates.

Il est à noter que, en cas de défaillance du collage, les plaquettes restent maintenues sur les plaques par leurs barrettes.It should be noted that, in the event of failure of the bonding, the plates remain held on the plates by their bars.

Il faut souligner la facilité et la rapidité de mise en oeuvre des panneaux sur chantier, provenant en particulier du nombre très limité de plaquettes complémentaires qui sont à mettre en place après fixation des panneaux (4 par panneau) et de l'extrême simplicité de cette mise en place grâce aux barrettes de maintien (pas d'accessoire de pressage).It should be emphasized the ease and speed of implementation of the panels on site, coming in particular from the very limited number of additional plates which are to be put in place after fixing the panels (4 per panel) and the extreme simplicity of this set up thanks to the holding bars (no pressing accessory).
