Description

The present invention relates to a covering panel and / or insulation

  from a building element, to a method for manufacturing such a panel, to an installation for carrying out this method as well as to the use of a panel.

  This invention relates to the field of the building and, more particularly, that of the cladding and / or the insulation of a wall, in particular a facade, or a floor, in particular a slab, that includes a such building. It is already known to dress and / or isolate the wall (brick, breeze block, concrete, cladding or other) of the facade of a building. To do this, it uses panels of insulating material, in particular polystyrene, positioned juxtaposed against the facade and made integral with the latter, in particular by gluing.

  After fixing these panels, it is often necessary to give them a surface state capable of allowing proper attachment of a coating subsequently applied to these panels. To do this, it is usual to plane, sand or scratch the surface of these panels which produces particularly fine and light particles. These particles are difficult to recover and fly away easily, which, on the one hand, generates persistent pollution since these particles are made of a durable material and, on the other hand, constitutes a health risk if ingested or inhalation of these particles. After having secured the panels of the facade, or even after having conferred on them an appropriate surface condition, a net is spread over the surface of the panels, especially over the entire height of the facade. Such a net is, then and usually, made integral with these panels, in particular by gluing, stapling or the like. It is then applied, over this net and over the panels, a coating layer over which is usually applied another layer of plaster.

  Finally, over this or these plaster layers, it is, again, applied at least one layer of plaster and / or paint, especially in the form of an underlayer. In this connection, it should be observed that the application of a second layer on a first layer requires waiting for the drying of this first layer. This expectation and the multiplication of steps to dress and / or isolate a facade represent the main drawbacks of this manner of proceeding. The present invention is intended to overcome the disadvantages of devices and methods of the state of the art, more particularly through a new covering panel and insulation and through the use of such a panel. For this purpose, the invention relates to a covering panel and / or insulation of a building element comprising a plate made of a material of structure and / or insulation and having two large faces substantially parallel and delimited by edges. This panel is characterized by the fact that it comprises a net comprising, on the one hand, a first portion extending over at least a portion of the surface of a large face of the plate and, on the other hand, on the other hand, at least a second portion extending beyond at least one edge of this large face of the plate. This panel further comprises a plaster layer, on the one hand, extending over at least a portion of the first portion of net or incorporating at least a portion of this first portion of net and, on the other hand, being set back from at least one edge of the large face of the plate, other than the one beyond which the second portion of this net extends. An additional feature is that the net has a first portion, either extending over the entire surface of the large face of the plate, or being recessed with respect to at least one edge (or even Ratio to two consecutive edges) of the large face of the plate.

  Another feature is that the net has a second portion extending beyond two consecutive edges that has the large face of the plate. In fact and preferably, this net comprises, on the one hand, a first portion extending over the entire surface of the large face of the plate and, on the other hand, a second portion extending beyond two consecutive edges of the large face of the panel plate. Another feature relates to the fact that the thread extends beyond two consecutive edges of the large face of the plate while the plaster layer is set back from the edges of the plate, other than those beyond which extends the net. The present invention further relates to a method for manufacturing a cladding and / or insulation panel having the aforementioned characteristics. This invention is, moreover, relating to an installation for the implementation of this manufacturing method. Finally, the invention relates to the use of such a covering panel and / or insulation for the cladding and / or insulation, as the case may be, of a wall or a floor that comprises a building. The advantages of the present invention are that the panels already include a net and a coating which makes it possible, during the dressing and / or the insulation of a support, to avoid the shaping steps. the surface of a panel, laying a net and applying a coating on the entire surface of the panels which allows a considerable reduction of dressing steps and / or insulation and 30 than a substantial time saving. The fact of not implementing a shaping step on a building site also makes it possible, advantageously, to avoid the production, dispersion and recovery of particles, to keep the worksite clean and to reduce the risk of pollution. .

  The presence of coating on part of the panels advantageously allows, after fixing these panels on a support, to apply coating on a particularly small part of such a panel (joint), more particularly at the level of the junction between two panels, especially at only two sides of such a panel, this on a band that can be of small width (in particular of the order of 5 to 15 cm). The duration of application of such a coating on site is particularly reduced compared to the method of the state of the art. In addition, a preferred embodiment of the invention consists in that the net comprises, on the one hand, a first portion extending over the entire surface of the large face of the plate and, on the other hand, a second portion extending beyond two consecutive edges of the large face of the panel plate. As for the coating, it is set back from at least one edge of the large face of the plate, other than that beyond which extends the second portion of the net. This advantageously allows the second net portion of a first panel to extend over the first net portion of a second panel, thus facilitating the subsequent fixing of the coating on the second panel, thereby ensuring stability of this coating and guaranteeing its integrity by avoiding cracks.

  Another advantage is that the establishment of these panels can be ensured whatever the weather conditions unlike certain stages of the prior art process whose performance, quality and / or performance (particularly the application of the coating) may be disturbed in bad weather. Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

  The present invention relates to the field of the building and, more particularly, that of the cladding and / or the insulation of a wall (in particular of a facade whose wall is made of concrete, bricks, blocks, in cladding or other) or a floor (including a slab for example concrete, earth or other) that includes such a building. In fact, this invention relates, then more particularly, a panel 1 covering and / or insulation as shown in the figures in the appendix and designed to ensure the dressing and / or insulation of an element 2 (wall or floor) that includes such a building. Such a panel 1 covering and / or insulation comprises, firstly, a plate 3 made of a structural material and / or insulation. In this regard, it will be observed that such a material may then be constituted, at least in part, by a mineral material or an organic material, or even by a composite material, in particular of inorganic / organic type. By way of examples (non-limiting), such a material may, at least in part, be constituted by polystyrene (expanded, extruded, molded or other), by a polymer foam (in particular a polyurethane foam, polyvinyl chloride). vinyl-PVC-, polyisocyanurate, a phenolic foam or other), a wool (especially glass, rock or other), a glass-foam complex (especially polymer as mentioned above) or other.

  In fact, such a plate 3 has two large faces 4, 4 'substantially parallel and one of which 4' is intended to be oriented in the direction of the element 2 (frontage or floor) of the building which must be provided. dressing and / or insulation. In this connection, it will be observed that such a plate 3 is preferably made integral with such an element 2.

  To do this and according to a first embodiment, this plate 3 can be glued to this element 2 by means of an adhesive that receives this plate 3 at the large face 4 ', oriented toward this element 2. According to another embodiment of the invention, this plate 3 can, again, be screwed or pegged on said element 2, this by means of screws or pins passing through this plate 3. However, according to a preferred embodiment of FIG. the invention, this plate 3 is equipped, at the large face 4 'oriented towards this element 2, means for the attachment of the panel 1 on a support integral with the element 2. Such a support can, in fact, be constituted by complementary fastening means equipping this element 2. A particular embodiment is that these attachment means and / or these additional attachment means can adopt the shape of a rail at the level of which is a finished coupling rim. As can be seen in the appended figures corresponding to a preferred (but not limiting) embodiment of the invention, such a plate 3 adopts, in fact, the shape of a parallelepiped, preferably rectangle. The two large faces 4, 4 'of such a parallelepipedal plate 3 are then delimited by edges 5, 5', 6, 6 'substantially parallel in pairs and constituted, on the one hand, by two longitudinal edges 5 , 5 'and, secondly, by two side edges 6, 6'. These two large faces 4, 4 'of such a plate 3 are, in fact, defined at a parallelepiped which also comprises sides 7, 7', 8, 8 'substantially parallel in pairs and constituted, on the one hand, by two longitudinal sides 7, 7 'and, on the other hand, by two lateral sides 8, 8'.

  These sides 7, 7 ', 8, 8' extend, preferably, substantially perpendicular to the large faces 4, 4 'of the plate 3, this at the level, respectively, of the edges 5, 5', 6 , 6 'delimiting these two large faces 4, 4'.

  According to another characteristic of the panel 1 according to the invention, the plate 3 comprises, on the one hand and at the level of at least one of the sides 7; 8 of this plate 3, interlocking means 9 and, on the other hand and at the level of at least one of the other sides 7 '; 8 'of this plate 3, complementary interlocking means 10. The interlocking means 9, respectively the complementary interlocking means 10, a plate 3 of a panel 1 are designed able to cooperate with the means of complementary interlocking 10A, respectively with the interlocking means 9A, that comprises the plate 3A of another panel 1A of identical structure, associated with this panel 1 and juxtaposed thereto 1 as shown in FIG. 3. An embodiment preferred embodiment of the invention is that the panel 1 comprises, on the one hand, interlocking means 9 defined at a longitudinal side 7 as well as at a lateral side 8 of the plate 3 of this panel 1 and, secondly, complementary engagement means 10 defined at the other longitudinal side 7 'and at the other side side 8' of the plate 3.

  As can be seen in the appended figures, such interlocking means 9 may, in fact, adopt the shape of a groove while the complementary interlocking means 10 may take the form of a rib. According to another characteristic, the panel 1 covering and / or insulation according to the present invention comprises, on the other hand, a thread 11 disposed over at least a portion of the surface of the large face 4 of the plate 3 of this panel 1, opposite that 4 'intended to be oriented towards the building element 2 to be dressed / insulated.

  In fact, such a net 11 has a first portion 12 extending over at least a portion of the surface of the large face 4 of the plate 3 of the panel 1. In this regard, it will be observed that, according to a first embodiment of the invention, this first portion 12 of net 11 is set back with respect to at least one edge 5; 6 of the large face 4 of this plate 3. Thus and as can be seen in FIG. 1, this first portion 12 of thread 11 may be set back with respect to a single edge 5 of the large face 4 of this plate 3. A Another embodiment not shown is that this first portion 12 of thread 11 is set back with respect to two consecutive edges 5 and 6 of the large face 4 of this plate 3. However, according to a preferred embodiment of FIG. 2, this first portion 12 of thread 11 extends over the entire surface of the large face 4 of the plate 3. According to another characteristic of the invention and as visible on the figures in the appendix, this net 11 comprises, still, at least a second portion 13 extending beyond at least one edge 5 '; 6 'that has the large face 4 of the plate 3 of a panel 1. Such a feature advantageously allows the second portion 13 of the net 11 of a first panel 1 to extend over at least one part of the surface of the large face 4A of the plate 3A of a second panel IA immediately juxtaposed with said first panel 1. In this regard, it will be observed that this second portion 13 of net 11 of this first panel 1 can, then, extend directly over the large face 4A of the plate 3A of a second panel 1A, this when the first portion 12A of thread 11A of the second panel 1A is set back with respect to an edge 5A; 6A of the large face 4A of the plate 3A of this second panel 1A.

  However, and according to a preferred embodiment of the invention illustrated in FIG. 3, this second portion 13 of thread 12 of this first panel 1 extends over a first portion 12A of thread 11A of a second panel 1A, this when this first portion 12A of thread 11A is not located (or is insufficiently) recessed with respect to an edge 5A; 6A of the large face 4A of the plate 3A of the second panel 1A, more particularly when this first portion 12A of thread 11A extends over the entire surface of the large face 4A of the plate 3A of this second panel lA (Figure 3). Also and according to a first embodiment illustrated in FIG. 1, this net 11 may comprise a second portion 13 extending beyond a single edge 5 'of the large face 4 of the plate 3. However, according to a method of preferred embodiment of the invention illustrated in Figure 2, this net 11 has a second portion 13 extending, in fact, beyond two edges 5 '; 6 'consecutive that has the large face 4 of a plate 3 of a panel 1. In such a case, a first embodiment is that the net 11 comprises, on the one hand, a second portion 13 of net 11 extending beyond two edges 5 '; 6 'consecutive that has the large face 4 of a plate 3 of a panel 1 and, secondly, a first portion 12 is set back relative to the other two edges 5; 6 consecutive that has this plate 3 and which are opposed to those 5 '; 6 'beyond which extends the second portion 13 of the net 11. However, a preferred embodiment of a panel 1 according to the invention consists, in fact, in that the net 11 of this panel 1 extends over the entire surface of the large face 4 of the plate 3 and beyond two consecutive edges 5; 6 of this large face 4 as illustrated in FIGS. 2 and 3.

  An additional feature is that the panel 1 has means for fastening the thread 11 to the plate 3 of the panel 1. Such fastening means may consist of a weld, glue, staples, or the like. . According to another characteristic of the invention, the covering panel 1 and / or insulation also comprises a plaster layer 14 extending over at least a portion (or even above all) of the first portion 12 of net 11 or incorporating at least a portion of first portion 12 of net 11. In addition, this plaster layer 14 is set back with respect to at least one edge 5; 6 of the large face 4 of the plate 3 other than that 5 '(or those 5', 6 ') beyond which (of which) 15 extends the second portion 13 of the net 11. Such a feature allows, advantageously defining at least one edge 5; 6 of the large face 4 of the plate 3 of a first panel 1, a portion 15 of plate 3 (seal) devoid of coating and over which 15 can then extend a second portion 13A of net 11A of a second panel IA immediately juxtaposed to said first panel 1. The presence of this portion 15 of plate 3 devoid of coating allows, advantageously, after positioning at least part of the panels 1 dressing and / or insulation at the level of the building element 2 to be dressed / insulated, to spread the coating only at this portion 15 of plate 3 (seal) to complete the dressing and / or the insulation of this element 2 of building. This advantageously makes it possible to avoid, on a building site, spreading plaster over the entire surface of the insulating panels added to a building element 2 as in the state of the art. In fact, a preferred embodiment of the invention is that the net 11 extends beyond two consecutive edges 5 ', 6' of the large face 4 of the plate 3 while the plaster layer 14 is set back from the edges of 5, 6 the plate 3, other than those 5 ', 6' beyond which extends the net 11. According to another characteristic, this coating layer 14 can, then , extend over the entirety of the first portion 12 of net 11 or, again, incorporate all of this first portion 12 of net 11. This is, more particularly, the case when the first portion 12 of net 11 is set back from at least one edge 5; 6 in the large face 4 of the plate 3. In such a case, the coating layer 14 is preferably flush with the first portion 12 of net 11 at the edge of the net 11. However, and according to a preferred embodiment embodiment of the invention, this plaster layer 14, on the one hand, extends over a portion of the first portion 12 of thread 11 which, it extends over all of the surface of the large face 4 of the plate 3 of the panel 1 and, on the other hand, is set back with respect to at least one edge 5; 6 of the large face 4 of the plate 3 other than that 5 '(or those 5; 6') beyond which (of which) extends the second portion 13 of the net 11. An additional feature is that the portion 15 of the plate 3 of a panel 1 devoid of coating has a width which is at least equal to that of the second portion 13 of thread 11 intended to extend over the plate 3A of another panel 1A similar. According to a preferred embodiment of the invention, this coating may be constituted by an undercoat coating, by an adhesive (in particular cement-adhesive type, for example of traditional composition, or even more elaborate), by a cement- fiber or other. An additional feature of the panel 1 according to the invention is that the plate 3 has, at its large face 4, means designed to allow a fixing of the coating layer 14 on the plate 3.

  Such fastening means are preferably constituted by means for anchoring the coating layer 14 in the form of grooves (in particular in the form of a dovetail) or the like formed on the large face 4.

  In this regard, it will be observed that such fastening means allow, also and advantageously, a fixing of the thread 11 on the plate 3, this through the fixing of the coating 14. The invention also relates to a method for manufacturing a cladding and / or insulation panel 1 having the features described above. This process consists, first of all, in that one proceeds to the manufacture of a plate 3 of a material of structure and / or insulation. This manufacture can be ensured by molding, in particular by injection, casting in a mold or the like. During such an operation, it is possible to give this plate 3 its appropriate dimensions, to define the interlocking means 9 as well as the complementary interlocking means 10, or even the fixing means of the coating 14. However, according to another embodiment, this manufacture can be ensured and / or completed by machining in order to cut the plate 3 to the appropriate dimensions and / or to make complementary interlocking / nesting means and / or define the means of fixation. Such a machining operation advantageously makes it possible to use plates of conventional design and / or shape and / or dimensions, in particular provided by a manufacturer. After manufacture of such a plate 3, the method consists in the fact that a net 11 is affixed to a large face 4 of this plate 3. To do this and according to a first embodiment, a pre-cut net 11 is deposited. to the appropriate dimensions on this plate 3.

  However, according to another embodiment, a thread is wound on this plate 3, wound on a roll, and this net is cut to the appropriate dimensions. After having affixed the thread 11 on the plate 3, the presence of a plaster layer 14 is ensured on the large face 4 of the plate 3. This step of the method can be ensured by casting, by application or by projection of This coating may be completed by a step during which the coating is subjected to vibrations and / or by a step during which the coating is smoothed, more particularly Another step in this process is that the thread 11 and / or the plaster 14 are secured to the plate 3. In this regard, it will be observed that the fixing of the plaster 14 It is ensured by anchoring this coating 14 at the level of the plate 3. As regards the fastening of the thread 11, this can be ensured by welding, gluing, stapling or the like. However, such a fastening can still be ensured through the anchoring of the plaster 14. Finally, the method of manufacturing a panel 1 according to the invention consists in that the drying is carried out. of the panel 1 obtained by the preceding steps, especially in an oven. An additional feature of the invention is that it also relates to an installation for carrying out the method of manufacturing a covering panel 1 and / or 30 insulation. This installation comprises, mainly, a means for affixing a thread 11 on a large face 4 of a plate 3 and a means for ensuring the presence of a coating 14 on this large side 4. As regards the means to affix the net 11, it may comprise a device designed to deliver pre-cut nets 11 to the appropriate dimensions. Alternatively, such means may comprise a roller on which is wound a net 11 completed by means for cutting a portion of net 11 to the appropriate dimensions.

  Regarding the means for ensuring the presence of a coating 14 on this large face 4, it may be constituted by a means for casting, applying or projecting such a coating. This means can be supplemented by a vibration means and / or a smoothing means.

  Additionally, such an installation may include means to ensure the manufacture of a plate 3 by molding (as described above). Alternatively, this installation may include means designed to perform machining of a plate 3 as described above. This installation may also comprise means for fixing a net 11 and / or the coating 14 on such a plate 3. A particular embodiment is that this installation comprises, on the one hand, a chain on which a plate 3 moves and, on the other hand, different stations at which the various operations of the process are carried out (manufacture and / or machining of the plate 3, affixing a net 11, depositing the coating 14, drying). Finally, the invention relates to the use of such a covering panel 1 and / or insulation. Thus, and according to a first type of use, such a panel 1 may be used for the cladding and / or the insulation of a wall (in particular of a facade whose wall is made of concrete, in bricks, in blocks , cladding or other) of a building. In such a case, the covering and / or the insulation of such a wall consists, on the one hand, in ensuring the presence of a plurality of these panels 1 at the level of this wall and, on the other hand, to complete the joints (portions without coating) with the coating.

  In addition, it is still possible, after completing these joints, to apply plaster and / or a finish on such a coating, especially after application of an additional undercoat on this coating.

  However, and according to a second type of use, such a panel 1 can be used for the cladding and / or insulation of a floor (particularly a floor such as concrete, earth or other) that includes such building. Here again, the covering and / or the insulation of such a floor consists, on the one hand, in ensuring the presence of a plurality of these panels 1 at this floor and, on the other hand, in completing the joints (portions without coating) by coating. Additionally, it is necessary to cover these panels 1 by a coating, in particular consisting of tiling, carpet, parquet or other.
