Description

PANNEAU ANTI-FEU La présente invention concerne les panneaux anti-feu qui trouvent des applications particulièrement avantageuses, de par leurs structures, comme éléments, de parement pour tapisser des parois de tous corps de façon à les protéger d'un feu accidentel ou non. Il est connu que, pour protéger des parois des méfaits d'un feu, on les 10 tapisse de parement anti-feu. Tel est le cas par exemple de certains fours dont les parois sont tapissées de briques réfractaires. Il est évident que ce tapissage est pour le moins délicat, difficile, relativement coûteux, et qu'il n'est pas adapté pour certaines applications. Aussi, pour pallier ces inconvénients, il a été mis au point des 15 panneaux anti-feu de relativement grandes dimensions. Or, ce type de panneaux connu à ce jour ne donne pas réellement satisfaction. Aussi, la présente invention a-t-elle pour but de réaliser un panneau anti-feu de grandes dimensions qui tente de pallier en grande partie les inconvénients des panneaux anti-feu de l'art antérieur. 20 Plus précisément, la présente invention a pour objet un panneau anti-feu caractérisé par le fait qu'il comprend : - deux plaques sensiblement planes, respectivement une plaque dite "interne" et une plaque dite "externe", au moins ladite plaque externe étant en un matériau réfractaire, et 25 - une couche intermédiaire comportant au moins une plaque dite "intermédiaire" définissant un plan général, ladite plaque intermédiaire comportant deux groupes de déformations en saillie dont les sommets sont situés de part et d'autre du dit plan général en définissant deux premier et second ensembles de sommets, ces dits premier et second ensembles de 30 sommets étant situés respectivement sur deux plans sensiblement parallèles au dit plan général, ladite couche intermédiaire étant intercalée au contact entre les deux plaques interne et externe.FIELD OF THE INVENTION The present invention relates to fireproof panels which find particularly advantageous applications, because of their structures, as facing elements for upholstering the walls of all bodies so as to protect them from accidental fire or not. It is known that in order to protect the walls from the harmful effects of a fire, they are lined with fireproof facing. This is the case for example of some furnaces whose walls are lined with refractory bricks. It is obvious that this upholstery is difficult to say the least, difficult, relatively expensive, and that it is not suitable for certain applications. Also, to overcome these drawbacks, relatively large fireproof panels have been developed. However, this type of panels known to date does not really satisfactory. Also, the object of the present invention is to provide a large fireproof panel which attempts to overcome in large part the disadvantages of the fireproofing panels of the prior art. More specifically, the subject of the present invention is an anti-fire panel, characterized in that it comprises: two substantially flat plates, respectively a so-called "internal" plate and an "external" plate, at least said external plate; being made of a refractory material, and an intermediate layer comprising at least one so-called "intermediate" plate defining a general plane, said intermediate plate comprising two groups of projecting deformations whose vertices are situated on either side of said plane general by defining two first and second sets of vertices, said first and second sets of 30 vertices being located respectively in two planes substantially parallel to said general plane, said intermediate layer being interposed in contact between the two inner and outer plates.

Selon une caractéristique préférentielle, le panneau comprend des moyens pour fixer les plaques interne et externe respectivement sur les sommets des premier et second ensembles de sommets, ces moyens de fixation permettant en outre un déplacement de la plaque externe par rapport à la couche intermédiaire selon au moins une direction parallèle au plan général. D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description suivante donnée en regard des dessins annexés à titre illustratif mais nullement limitatif, dans lesquels : Les figures 1 à 4 représentent un premier mode de réalisation du panneau anti-feu selon l'invention, la figure 1 étant une vue en perspective cavalière du panneau, la figure 2 étant une vue en coupe de côté d'une partie du panneau selon la* figure 1, les figures 3 et 4 représentant deux vues d'une configuration possible du panneau au cours de son assemblage, La figure 5 représente un mode de réalisation d'un élément constitutif d'un deuxième mode de réalisation du panneau anti-feu selon l'invention, La figure 6 est une vue en coupe de côté d'une partie du panneau comportant trois éléments superposés, chacun de ces trois éléments étant conforme à celui illustré sur la figure 5, et La figure 7 représente un troisième mode de réalisation du panneau selon l'invention. Il est tout d'abord précisé que, sur les figures, les mêmes références désignent les mêmes éléments, quelle que soit la figure' sur laquelle elles apparaissent et quelle que soit la forme de représentation de ces éléments.According to a preferred feature, the panel comprises means for fixing the inner and outer plates respectively on the tops of the first and second sets of apices, these fixing means further allowing movement of the outer plate relative to the intermediate layer according to minus a direction parallel to the general plane. Other features and advantages of the present invention will become apparent from the following description given with reference to the accompanying drawings for illustrative but not limiting purposes, in which: FIGS. 1 to 4 show a first embodiment of the fireproof panel according to FIG. 1 being a side perspective view of the panel, FIG. 2 being a side sectional view of a portion of the panel according to FIG. 1, FIGS. 3 and 4 showing two views of a configuration. FIG. 5 shows an embodiment of a constituent element of a second embodiment of the fireproof panel according to the invention. FIG. 6 is a side sectional view of the panel. FIG. a part of the panel comprising three superimposed elements, each of these three elements being in accordance with that illustrated in FIG. 5, and FIG. 7 represents a third embodiment of the panel u according to the invention. It is first of all specified that, in the figures, the same references designate the same elements, whatever the figure on which they appear and whatever the form of representation of these elements.

De même, si des éléments ne sont pas spécifiquement référencés sur l'une des figures, leurs références peuvent être aisément retrouvées en se reportant à une autre figure. Il est aussi précisé que les figures représentent un certain nombre de modes de réalisation de l'objet selon l'invention, mais qu'il peut en exister d'autres qui répondent à la définition de cette invention. Il est en outre précisé que, lorsque, selon la définition de l'invention, l'objet de l'invention comporte "au moins un" élément ayant une fonction donnée, le mode de realisation décrit peut comporter plusieurs de ces éléments. Réciproquement, si le mode de réalisation de l'objet selon l'invention tel qu'illustré comporte plusieurs éléments de fonction identique et si, dans la description, il n'est pas spécifié que l'objet selon cette invention doit obligatoirement comporter un nombre particulier de ces éléments, l'objet de l'invention pourra être défini comme comportant "au moins un" de ces éléments.. Il est enfin précisé que lorsque, dans la présente description, une expression définit à elle seule, sans mention particulière spécifique la concernant, un ensemble de caractéristiques structurelles, ces caractéristiques peuvent être prises, pour la définition de l'objet de la protection demandée, quand cela est techniquement possible, soit séparément, soit en combinaison totale et/ou partielle. Il est enfin précisé que, dans la présente description, si l'adverbe "sensiblement" est associé à un qualificatif d'un moyen donné, ce qualificatif 15 doit être compris au sens strict ou approché. Ceci ayant été précisé, la présente invention concerne un panneau anti-feu qui se caractérise essentiellement, en regard des figures 1 à 3, par le fait qu'il comprend au moins, deux plaques sensiblement planes, respectivement une plaque dite "interne" 11 et une plaque dite "externe" 12, 20 au moins la plaque externe 12 étant en un matériau réfractaire, par exemple un matériau composite à matrice céramique CMC qui est connu en lui-même. Le panneau comporte une couche intermédiaire 20 comprenant au moins *une ,plaque 21, 22, 23, ... dite "intermédiaire" définissant un plan 25 général Pg. La plaque intermédiaire 21, 22, 23, ... comporte deux groupes de déformations en saillie 31, 32 dont les sommets 311, 321 sont situés de part et d'autre du plan général Pg en définissant un premier et un second ensembles de sommets 311-1, 321-2, ces premier et second ensembles de 30 sommets étant situés respectivement sur deux plans sensiblement parallèles au plan général Pg, la couche intermédiaire 20 étant intercalée au contact entre les deux plaques interne 11 et externe 12, figures 1 et 2.Similarly, if elements are not specifically referenced in one of the figures, their references can be easily found by referring to another figure. It is also stated that the figures represent a number of embodiments of the object according to the invention, but that there may be others that meet the definition of this invention. It is furthermore specified that, when, according to the definition of the invention, the object of the invention comprises "at least one" element having a given function, the embodiment described may comprise several of these elements. Conversely, if the embodiment of the object according to the invention as illustrated has several elements of identical function and if, in the description, it is not specified that the object according to this invention must obligatorily comprise a number particular of these elements, the object of the invention may be defined as comprising "at least one" of these elements. Finally, it is specified that when, in the present description, an expression defines on its own, without specific particular mention. concerning it, a set of structural characteristics, these characteristics can be taken, for the definition of the object of the protection requested, when it is technically possible, either separately, or in total and / or partial combination. Finally, it is pointed out that, in the present description, if the adverb "substantially" is associated with a qualifier of a given means, this qualifier must be understood in the strict sense or approached. This having been specified, the present invention relates to an anti-fire panel which is essentially characterized, with regard to FIGS. 1 to 3, in that it comprises at least two substantially flat plates, respectively a so-called "internal" plate. and a so-called "outer" plate 12, 20 at least the outer plate 12 being made of a refractory material, for example a CMC ceramic matrix composite material which is known per se. The panel comprises an intermediate layer 20 comprising at least one plate 21, 22, 23, ... known as "intermediate" defining a general plane Pg. The intermediate plate 21, 22, 23, ... comprises two groups of protruding deformations 31, 32 whose vertices 311, 321 are situated on either side of the general plane Pg by defining a first and a second set of vertices 311-1, 321-2, these first and second sets of 30 vertices being respectively located in two planes substantially parallel to the general plane Pg, the intermediate layer 20 being interposed in contact between the two inner plates 11 and outer 12, Figures 1 and 2.

Selon un mode de réalisation, la plaque interne 11 est avantageusement fixée sur le premier ensemble de sommets 311-1, par exemple par collage, soudage, brasage, etc. Quant à la plaque externe 12, elle est, selon une réalisation possible, juste positionnée au contact du second ensemble de sommets 321-2 de façon que, si elle est soumise à une forte température comme celle générée par un feu, elle puisse se dilater sans transmettre à la couche intermédiaire et donc à la couche interne 11, les efforts engendrés par sa dilatation. Cependant, une telle réalisation présente un inconvénient qui apparaît à l'évidence lorsque le panneau doit être manipulé. Aussi, de façon très préférentielle, comme illustré sur la figure 4, le panneau comprend des moyens pour fixer les plaques interne 11 et externe 12 respectivement sur les sommets des premier et second ensembles de sommets 311-1, 321-2, au moins les moyens de fixation pour fixer la plaque externe 12 permettant en outre un déplacement de cette plaque externe par rapport à la couche intermédiaire 20 selon au moins une direction parallèle au plan général Pg. Ce mode de réalisation est préférentiel quand cette plaque externe 12 est destinée à être directement en regard d'un feu.According to one embodiment, the inner plate 11 is advantageously fixed on the first set of peaks 311-1, for example by gluing, welding, soldering, etc. As for the outer plate 12, it is, according to a possible embodiment, just positioned in contact with the second set of vertices 321-2 so that, if it is subjected to a high temperature such as that generated by a fire, it can expand. without transmitting to the intermediate layer and therefore to the inner layer 11, the forces generated by its expansion. However, such an embodiment has a drawback which obviously appears when the panel must be manipulated. Also, very preferably, as illustrated in FIG. 4, the panel comprises means for fixing the inner and outer plates 11 and 12 on the vertices of the first and second sets of vertices 311-1, 321-2, respectively. fixing means for fixing the outer plate 12 further allowing displacement of the outer plate relative to the intermediate layer 20 in at least one direction parallel to the general plane Pg. This embodiment is preferred when this outer plate 12 is intended for to be directly facing a fire.

Il est préférable que ces moyens de fixation permettent le déplacement de la plaque externe 12 par rapport à la couche intermédiaire 20 selon toute direction parallèle au plan général Pg dans un angle de 360 degrés. .Dan È une réalisation avantageuse, les moyens de fixation de la plaque externe 12 définis ci-dessus sont constitués par au moins une pastille 40 (de préférence une pluralité de pastilles, figure 4) en un matériau collant présentant, après collage, une certaine élasticité, cette pastille étant intercalée entre un sommet 321 du premier ensemble de sommets 321-2 et la plaque externe 12. Dans un mode de réalisation particulièrement préférentiel, le matériau constituant la pastille 40 est une colle à base de silicone. Il est précisé que les pastilles peuvent avoir différentes formes et tailles qui seront très facilement déterminées par l'homme du métier.It is preferable that these fastening means allow the displacement of the outer plate 12 relative to the intermediate layer 20 in any direction parallel to the general plane Pg in a 360 degree angle. In an advantageous embodiment, the fastening means of the outer plate 12 defined above are constituted by at least one pellet 40 (preferably a plurality of pellets, FIG. 4) of a tacky material having, after bonding, a certain amount of elasticity, this chip being interposed between a vertex 321 of the first set of vertices 321-2 and the outer plate 12. In a particularly preferred embodiment, the material constituting the patch 40 is a silicone-based glue. It is specified that the pellets may have different shapes and sizes that will be very easily determined by the skilled person.

Comme plus particulièrement illustré sur les figures 1-4, 6 et 7, il est préférable que la couche intermédiaire 20 soit constituée d'une pluralité de plaques intermédiaires 21, 22, 23, ..., chaque plaque intermédiaire comportant des déformations en saillie et ces plaques intermédiaires étant fixées les unes sur les autres de façon que leurs plans généraux Pg', Pg" soient sensiblement parallèles entre eux. Sur les figures illustrant ces plaques intermédiaires, les déformations sont de différentes formes, par exemple comme des tôles ondulées dont les ondulations ont des sections qui peuvent être courbes, par exemple en 10 demi-cercle ou analogue, ou trapézoïdales ou analogue, etc. Cependant, selon une réalisation avantageuse, ces déformations en saillie 31, 32 sont, figure 5 et 6, en forme de cuvettes, le fond de ces cuvettes constituant les sommets 321, 311 définis ci-avant, les cuvettes situées d'un côté du plan général Pg pouvant avoir des formes et des 15 profondeurs identiques à celles des cuvettes situées de l'autre côté de ce plan Pg, ou différentes, en soulignant cependant que les profondeurs des cuvettes situées d'un même côté du plan général Pg sont toutes sensiblement identiques. Ainsi, comme illustré à titre d'exemple sur les figures 5 et 6, les 20 cuvettes dont les fonds constituent l'un 321-2 des deux ensembles de sommets ont une profondeur supérieure à celle des cuvettes dont les fonds constituent l'autre ensemble de sommets 311-1. Dans le mode de réalisation selon la figure 6, les fonds des cuvettes de la plus grande profondeur d'une plaqué intermédiaire 21, 22, 23, ... sont fixés sur les fonds des cuvettes de 25 la plus faible profondeur d'une autre plaque intermédiaire 21, 22, 23, .... Dans tous les modes de réalisation du panneau selon l'invention décrits ci-dessus, il peut être avantageux, au moins pour certaines applications, que le panneau comporte en outre des moyens de cerclage 50 entourant à la fois les bords Bd de la plaque externe 12, de la plaque interne 30 11 et de la couche intermédiaire 20. Selon une réalisation préférentielle, ce cerclage comporte une enveloppe extérieure 51 en un matériau relativement rigide, et un joint 52 intercalé entre cette enveloppe 51 et les bords Bd, ce joint 52 optionnellement intumescent étant réalisé en un matériau élastique. Le panneau selon l'invention peut être utilisé pour tapisser des parois peu résistantes au feu d'un endroit, milieu, etc., où peut se produire de façon accidentelle ou non un feu important, en positionnant le panneau (ou les panneaux) de façon que la face externe 12 soit tournée vers le foyer du feu possible. Un panneau selon l'invention tel que décrit ci-dessus peut être de très grandes dimensions et trouve une application particulièrement avantageuse pour tapisser les parois d'un véhicule de tout type apte à transporter, par exemple, un autre véhicule qui contient des produits très inflammables, par exemple, de l'essence, du kérosène ou analogue.
