Definitions
- the invention relates to an insulating and fire-resistant panel of polygonal shape, more particularly of rectangular shape and intended to be arranged with other identical or similar panels so as to form an insulating wall and resistant to fire. More particularly, the panels are of the sandwich type having a core of insulating material covered with a finishing sheet. This type of construction is particularly suitable for cold room cladding which requires good insulation.
- Polyurethane foam is a cellular insulation, composed of fine cells storing a gas with low thermal conductivity. It is very used in the building. Polyurethane is however a flammable material. In the United Kingdom, Ireland and some US states, regulations require upholstered furniture manufacturers (sofas, mattresses) to treat products with fire-retardant chemical additives to reduce this risk. Many areas of use of polyurethane foams require "non-fire" properties. In the building sector, for public places, foams must be treated with fire. The use of this insulation is subject to an increased fire risk for insurers. Used in a metal cladding, it releases an acid in case of fire that destroys the metal siding and damages the strength of the building structure
- room vests constructed with polyurethane sandwich panels must be able to maintain their stability for a specified period of time during a fire. They must be constructed in such a way that the spread of fire and smoke is restricted to the interior of the chamber in question so as to limit the spread of fire.
- the patent document DE 295 18 473 U discloses an insulating sandwich panel and fire resistant. It includes a metal finishing sheet on each side, reinforcing sleepers made of calcium silicate material or reinforced mineral or ceramic fibers.
- the core of the panel is filled with insulating material such as rockwool, ceramic fiber or calcium silicate.
- This type of material poses problems of microbial proliferation. In addition, it does not exhibit dimensional stability and mechanical rigidity comparable to a rigid material such as polyurethane foam or cellular glass. It is probably for this reason that the back of the panel is also covered with a metal sheet and that the panel includes several reinforcing crosspieces.
- the termination of the edges of the panel is provided by longitudinal members of material similar to the sleepers.
- These longitudinal members have on their outer faces forming the slices of the panel grooves for cooperating with a folded edge of the metal sheets.
- the assembly of the panels is done by approximation and superposition of the edges possibly having corresponding profiles.
- the document does not further specify how the panels are attached to the structure to receive the cladding.
- the construction of the panel described in this document is not intended for a core of rigid material given the many reinforcements and the flexible nature of the insulating material intended to equip it.
- the connection between the metal sheets and the longitudinal members is interesting but requires the presence of a retaining members of both sides of the panel, given the absence of bonding between the longitudinal members and the insulating material.
- the object of the invention is to propose a sandwich panel that overcomes at least one of the aforementioned problems.
- the invention consists of an insulating and fire-resistant panel of polygonal shape comprising: a core made of a first insulating material; a metal sheet covering the soul on one side; at least two tabs of a second insulating and rigid material forming at least two opposite edges of the panel; where said tongues comprise at least one hole near each corner of the panel, perpendicular to the face of the tongue forming the edge of the panel and preferably near the face of the core opposite to the face provided with the metal sheet, said hole being adapted to cooperate by engagement with an ankle disposed in the corresponding hole of an identical adjacent panel.
- the second material is of higher density, preferably by a factor greater than or equal to 5, to that of the first material, so as to ensure proper holding of the dowels in the holes of the tongues.
- the reference to the face of the core provided with the metal sheet in the definition of the invention above and in the optional features that follow preferably corresponds to the visible or external face of the panel once mounted. It does not exclude the present of a second sheet on the opposite face, preferably hidden or interior.
- the invention can in fact be made with a second metal sheet disposed on the opposite face of the panel, more particularly the insulating core, as in the embodiment.
- the first insulating material of the core is rigid and, preferably, the tongues are glued to said core. This measurement provides interesting mechanical stability, especially with respect to fire protection.
- the metal sheet is glued to the core. This measurement also provides an interesting mechanical stability, particularly with respect to fire protection.
- the panel comprises a layer of the second material disposed between the core and the metal sheet; the metal sheet, the layer of the second material and / or the core being preferably assembled by gluing.
- this measurement ensures an interesting mechanical stability, especially with respect to fire protection.
- the layer of the second material disposed between the core and the metal sheet is typically between 5% and 20% of the total thickness of the panel. It is therefore a thin layer relative to the thickness of the core constituting most of the thickness of the panel.
- the metal sheet comprises at least two folded edges on the tongues, each forming an edge and fixed to said tongues by screwing, preferably near the edge on the half of the edge of the panel. on the side of the ridge.
- the tongues have a thickness measured in the plane of the panel of at least 10 mm and said second material is such that it allows to screw a self-tapping screw.
- the second material is of higher density, preferably by a factor greater than or equal to 5, to that of the first material.
- the panel comprises at least one reinforcing angle of sheet metal conforming to the edge of one of the tongues and covering the face of the tongue forming the edge of the panel from said edge sufficiently that for covering the holes intended to cooperate by engagement with dowels, said angle being preferably fixed by screwing in the tongue.
- the face of at least one of the tongues is provided with intumescent paint, preferably on its central zone, more preferably still between the reinforcing angle and the folded edge of the metal sheet.
- the first material is based on cellular glass and / or the second material is based on reinforced magnesium silicate.
- the panel comprises four tongues opposite in pairs made in the second insulating and rigid material.
- the invention also consists of an insulating wall and fire resistant comprising at least four panels such as that described above, said panels being arranged contiguously substantially in the same plane and with, for each panel, at least two edges arranged each facing a corresponding edge of another of said panels with, for at least one pair of face-to-face edges, at least one, preferably two pins cooperating by engagement with the corresponding holes of said pair of edges, the wall also comprising at least one plate comprising at least two holes and arranged astride two aligned edges of two of said panels, on either side of said pair of face-to-face edges, the holes of the plate being positioned each, through one of the pegs cooperating with a hole in one of the two aligned edges, near the junction of said pair of edges facing each other. face.
- the plate comprises an angled part intended to be fixed preferably by screwing to a wall or a wall opposite the faces of the panels opposite to those covered with the metal sheet.
- the plate is generally flat and comprises a hole remote from the faces of the panels opposite to those covered with the metal sheet, and intended to cooperate with fastening means suspended from a ceiling.
- a seal is placed between the two folded edges and face to face of the metal sheets of two contiguous panels, close to the outer surface of said sheets, the fastening screws of said folded edges being remote from corresponding edges so as to provide the necessary space for said seal.
- the gasket is fire-resistant material and is of circular section inserted by insertion or is applied by extrusion.
- the figure 1 is a perspective view of a panel according to the invention. It includes an enlarged view of a corner of the panel illustrating different construction details.
- the figure 2 is a sectional view of two panels according to the invention, superimposed vertically and dressing a wall or a wall.
- the figure 3 is a perspective view of an assembly of three panels according to the invention intended to dress a wall or a wall.
- the figure 4 is a sectional view of a panel according to the invention covering the bottom of a wall or a wall and in contact with the ground.
- the figure 5 is a plan view of the cladding of the upper part of a wall or wall and ceiling by means of panels according to the invention.
- the figure 6 is a perspective view of detail of the junction of three panels according to the invention, also illustrating the suspension means of the panels to the ceiling.
- the insulating and fire resistant board 2 shown in figure 1 consists of a cellular glass core (not visible at the figure 1 ) whose shape corresponds essentially to that of the panel, this core being covered on its rear face with a metal sheet 8 and on its front face of a thin fibro-silicate panel, itself covered with a metal sheet 10 on its outer face.
- Tongues 4 and 12 of fibro-silicate are provided on the periphery of the insulating core so as to form the edges of the insulating panel.
- These tongues are preferably arranged by gluing on the edges of the thin fibro-silicate panel thereby forming a parallelepipedal volume capable of receiving the insulating core.
- the metal sheet 8 forming the rear face of the panel 2 has two edges bent at about 90 ° at two opposite ends so as to partially cover the tabs or opposite edges 12 of the panel 2.
- Metal brackets 6 made from pieces of sheet metal which are then folded are arranged on the edges of the rear face of the panel 2 which are not covered by the sheet 8. These angles are preferably unequal so as to have a longer edge on the tongue 4 than on the rear face of the panel 2
- the panel comprises two angles, one on each opposite side of the panel 2 where the rear plate 8 does not cover the wafer. Each angle 6 extends over substantially the entire length of the edge of the panel 2. They are fixed by means of screws 16, preferably at least one near each end of the edge to be covered.
- Each bracket 6 comprises at least one hole or hole 18 near each end. This orifice is in correspondence with a hole or orifice 18 made in the tongue 4, thus serving as a reinforcement of said orifice. The orifice 18 will serve as a connecting means of two adjacent panels.
- the front face of the panel 2 is covered with a metal sheet 10, preferably the four edges are folded at about 90 ° so as to cover the four edges of said face and also a portion of the tongues 4 and 12 forming the edges or edges of the panel 2. These folded edges are attached to the opposite tabs 4 by means of screws 14.
- the construction of the panel 2 can be better understood in view of the figure 2 which is a sectional view of two pieces of vertically superposed panels and covering a wall or a wall 26.
- the layer of insulating material 22 is observed, such as cell glass constituting the core of the panel to be insulating and fire resistant.
- This core of insulating material is covered with a thin layer 20 also insulating material but substantially more resistant from a mechanical point of view, such as fibro-silicate.
- the insulating core 22 and the thin layer 20 constitute the major part of the thickness of the panel.
- the panel 2 comprises four tongues, namely two tongues 4 of a first thickness on the two opposite edges comprising the orifices 18 and two tongues of a second thickness on the other two remaining opposite edges which themselves are not necessarily provided with means of linking the panels together.
- the tongues 4 of a first thickness typically have a thickness of the order of 12 mm and the tongues 12 of a second thickness typically have a thickness of about 6 mm. It should be noted that these values are purely illustrative.
- the choice of the material of the insulating core will depend on various parameters, such as the cost price, the quality of insulation, health constraints such as the risk of microbial proliferation and / or resistance to high temperatures.
- the insulating core 22 will typically be made of Foamglass® T4, namely aluminosilicate cellular glass.

- the thickness will be between 40 and 160 mm, more particularly between 40 and 100 mm, typically of the order of 60 mm.
- the thin layer 20 and the tongues 4 and 12 will be made of insulating material incombustible and having a certain mechanical strength, such as for example FIBRODICE MS based on magnesium silicate reinforced.
- the mechanical properties of this material allow it to be sanded, sawn, drilled, nailed, screwed and / or glued. It has a density of the order of 1 (1.050 ⁇ 0.1), a modulus of elasticity of between 5210 and 7845 N / mm 2 and a flexural strength of between 12.1 and 17.1 N / mm 2 .
- Silicates are minerals whose skeleton is essentially formed by Silicon and Oxygen tetrahedra supplemented with aluminum, magnesium, iron, calcium, potassium, sodium and other elements.
- Special purpose glass fibers are microfibers artificial glassy silicates with random orientation and whose weight percentage of alkaline oxides and alkaline earth oxides is greater than 18%. The diameter of these fibers is between 0.01 and 3 microns.
- the presence of the thin layer 20 between the insulating core and the front metal sheet 10 is not mandatory. Indeed, although this layer has a role of mechanical reinforcement and protection of the insulating core, its presence remains optional depending, in particular, thermal and mechanical stresses of the panel and the choice of material for the insulating core. The same goes for the tabs 12 ( figure 1 ) forming the edges of the panel which are not intended to cooperate with the connecting means of the panels together.
- the front face of the thin layer 20 is covered with a metal sheet 10.
- the metal sheet 10 comprises at least two opposite edges, ideally the four edges, which are bent at about 90 ° at their ends so as to match the outer shape of the front face of the panel. These folded edges conform to the edges of the front face of the panel and cover a portion, typically at least a quarter, more particularly at least one third of the height of the tongue 4 forming the edge of the panel.
- the rear face of the panel more particularly the rear face of the core 22 is covered with a metal sheet 8.
- the edges thereof is bent approximately at the edges of the tabs 4, so as to be covered with a metal bracket 6 reinforcement.
- the metal sheet of the front face 10 typically has a thickness of the order of 1 mm. Other thicknesses are of course possible depending on the mechanical properties of the sheet and the constraints to which the sign is submitted. The thickness will typically vary between 0.5 mm and 2 mm, preferably between 0.6 and 1.2 mm.
- the role of the sheet 10 is to ensure a mechanical strength of the panel (shape retention and resistance to penetration during contact with objects), an aesthetic finish, a flame protection screen and a finish compatible with sanitary standards. in force, in particular for the storage of foodstuffs.
- the sheet may be Aluzinc® which is a flat carbon alloy product composed of 55% aluminum, 43.4% zinc and 1.6% silicon. The steel is continuously coated on a dip galvanizing line.
- Aluzinc® results from the characteristics of its two metallic components: aluminum on the surface of the coating acts as a barrier to corrosion agents, zinc protects the steel by "sacrificial" effect .
- Aluzinc® has an aesthetic appearance due to its characteristic silver-colored flush. The surface of the metal deposit is protected by a thin layer of aluminum oxides ensuring the longevity of its brightness.
- the rear metal sheet 8 is typically thinner because it comes in addition to the front sheet 10. It provides additional reinforcement of the panel but especially closes the rear face to prevent any microbial proliferation towards the inside of the panel. It should be noted that this rear plate is not indispensable from a mechanical strength point of view of the panel, nor from a point of view of quality of insulation and nor from a point of view of protection against fire. Depending on the application, the sheet metal can be avoided, leaving free the back of the core of insulating material or leaving room for a finishing cover of another type such as a flexible film.
- the metal sheet 8 typically has a thickness of the order of 0.5 mm. It may however vary between 0.2 and 1 mm depending on the material and the mechanical properties of the sheet and also depending on the application of the panel.
- the sheet 8 is typically a galvanized steel sheet. It may be Aluzinc® like the front sheet 10 but it is clear that the aesthetic qualities of Aluzinc® will not be useful given the fact that it constitutes the rear face of the panel which is normally intended to be not visible.

Abstract
Description
L'invention a trait à un panneau isolant et résistant au feu de forme polygonale, plus particulièrement de forme rectangulaire et destiné à être disposé avec d'autres panneaux identiques ou similaires de sorte à former une paroi isolante et résistante au feu. Plus particulièrement encore, les panneaux sont du type sandwich comportant une âme en matériau isolant recouverte d'une tôle de finition. Ce type de construction est particulièrement indiqué pour la vêture de chambre froide qui requiert une bonne isolation.The invention relates to an insulating and fire-resistant panel of polygonal shape, more particularly of rectangular shape and intended to be arranged with other identical or similar panels so as to form an insulating wall and resistant to fire. More particularly, the panels are of the sandwich type having a core of insulating material covered with a finishing sheet. This type of construction is particularly suitable for cold room cladding which requires good insulation.
La mousse de polyuréthane est un isolant alvéolaire, composé de fines cellules emmagasinant un gaz à faible conductivité thermique. Elle est très utilisée dans le bâtiment. Le polyuréthane est cependant un matériau inflammable. Au Royaume-Uni, en Irlande, et dans certains États des USA, la réglementation oblige les fabricants de meubles rembourrés (canapés, matelas) à traiter les produits à l'aide d'additifs chimiques ignifugeants afin de réduire ce risque. De nombreux domaines d'utilisation des mousses de polyuréthane exigent des propriétés "non-feu". Dans le domaine du bâtiment, pour les lieux publics, les mousses doivent être traitées non feu. L'utilisation de cet isolant fait l'objet d'une aggravation du risque incendie pour les assureurs. Utilisé dans un bardage métallique, il dégage un acide en cas d'incendie qui détruit le bardage métallique et nuit à la solidité de la structure du bâtimentPolyurethane foam is a cellular insulation, composed of fine cells storing a gas with low thermal conductivity. It is very used in the building. Polyurethane is however a flammable material. In the United Kingdom, Ireland and some US states, regulations require upholstered furniture manufacturers (sofas, mattresses) to treat products with fire-retardant chemical additives to reduce this risk. Many areas of use of polyurethane foams require "non-fire" properties. In the building sector, for public places, foams must be treated with fire. The use of this insulation is subject to an increased fire risk for insurers. Used in a metal cladding, it releases an acid in case of fire that destroys the metal siding and damages the strength of the building structure
Pour ces raisons, les vêtures de chambres construites avec des panneaux sandwich polyuréthane doivent être à même de maintenir leur stabilité pendant une durée déterminée lors d'un incendie. Elles doivent être construites de sorte à ce que la propagation du feu et des fumées soit limitée à l'intérieur de la chambre en question, de manière à limiter l'extension du feu.For these reasons, room vests constructed with polyurethane sandwich panels must be able to maintain their stability for a specified period of time during a fire. They must be constructed in such a way that the spread of fire and smoke is restricted to the interior of the chamber in question so as to limit the spread of fire.
Une solution consiste à prévoir un « sprinklage » mais cette solution reste d'application limitée car elle ne convient pas aux chambres froides à température négative. De plus, cette solution est assez lourde à mettre en oeuvre et, partant, assez coûteuse.One solution is to provide a "sprinklage" but this solution is of limited application because it is not suitable for cold rooms in negative temperature. In addition, this solution is quite cumbersome to implement and therefore quite expensive.
Le document de brevet
L'invention a pour objectif de proposer un panneau sandwich palliant au moins un des problèmes sus mentionnés.The object of the invention is to propose a sandwich panel that overcomes at least one of the aforementioned problems.
L'invention consiste en un panneau isolant et résistant au feu de forme polygonale comprenant : une âme en un premier matériau isolant ; une tôle métallique recouvrant l'âme sur une face ; au moins deux languettes en un second matériau isolant et rigide formant au moins deux bords opposés du panneau ; où lesdites languettes comportent au moins un trou à proximité de chaque coin du panneau, perpendiculaire à la face de la languette formant la tranche du panneau et préférentiellement à proximité de la face de l'âme opposée à la face pourvue de la tôle métallique, ledit trou étant destiné à coopérer par engagement avec une cheville disposée dans le trou correspondant d'un panneau voisin identique. Cette solution permet un montage aisé, fiable et rapide d'une paroi constituée d'une série de pareils panneaux. Idéalement, le second matériau est de densité supérieure, préférentiellement par un facteur supérieur ou égal à 5, à celle du premier matériau, de manière à assurer une tenue correcte des chevilles dans les trous des languettes.The invention consists of an insulating and fire-resistant panel of polygonal shape comprising: a core made of a first insulating material; a metal sheet covering the soul on one side; at least two tabs of a second insulating and rigid material forming at least two opposite edges of the panel; where said tongues comprise at least one hole near each corner of the panel, perpendicular to the face of the tongue forming the edge of the panel and preferably near the face of the core opposite to the face provided with the metal sheet, said hole being adapted to cooperate by engagement with an ankle disposed in the corresponding hole of an identical adjacent panel. This solution allows an easy, reliable and fast assembly of a wall consisting of a series of such panels. Ideally, the second material is of higher density, preferably by a factor greater than or equal to 5, to that of the first material, so as to ensure proper holding of the dowels in the holes of the tongues.
La référence à la face de l'âme pourvue de la tôle métallique dans la définition de l'invention ci-dessus et dans les caractéristiques optionnelles qui suivent correspond préférentiellement à la face visible ou extérieure du panneau une fois monté. Elle n'exclut pas la présente d'une deuxième tôle sur la face opposée, préférentiellement cachée ou intérieure. L'invention peut en effet être réalisée avec une deuxième tôle métallique disposée sur la face opposée du panneau, plus particulièrement de l'âme isolante, comme dans l'exemple de réalisation.The reference to the face of the core provided with the metal sheet in the definition of the invention above and in the optional features that follow preferably corresponds to the visible or external face of the panel once mounted. It does not exclude the present of a second sheet on the opposite face, preferably hidden or interior. The invention can in fact be made with a second metal sheet disposed on the opposite face of the panel, more particularly the insulating core, as in the embodiment.
Selon un mode avantageux de l'invention, le premier matériau isolant de l'âme est rigide et, préférentiellement, les languettes sont collées à ladite âme. Cette mesure assure une stabilité mécanique intéressante, en particulier par rapport à la protection contre le feu.According to an advantageous embodiment of the invention, the first insulating material of the core is rigid and, preferably, the tongues are glued to said core. This measurement provides interesting mechanical stability, especially with respect to fire protection.

This measurement also provides an interesting mechanical stability, particularly with respect to fire protection.
Selon un encore autre mode avantageux de l'invention, le panneau comprend une couche du second matériau disposée entre l'âme et la tôle métallique ; la tôle métallique, la couche du second matériau et/ou l'âme étant préférentiellement assemblés par collage. Tout comme les mesures précédentes, cette mesure assure une stabilité mécanique intéressante, en particulier par rapport à la protection contre le feu. La couche du second matériau disposée entre l'âme et la tôle métallique représente typiquement entre 5% et 20% de l'épaisseur totale du panneau. Il s'agit donc d'une couche mince par rapport à l'épaisseur de l'âme constituant la majeure partie de l'épaisseur du panneau.According to yet another advantageous embodiment of the invention, the panel comprises a layer of the second material disposed between the core and the metal sheet; the metal sheet, the layer of the second material and / or the core being preferably assembled by gluing. Like the previous measurements, this measurement ensures an interesting mechanical stability, especially with respect to fire protection. The layer of the second material disposed between the core and the metal sheet is typically between 5% and 20% of the total thickness of the panel. It is therefore a thin layer relative to the thickness of the core constituting most of the thickness of the panel.
Selon un encore autre mode avantageux de l'invention, la tôle métallique comprend au moins deux bords pliés sur les languettes, formant chacun une arête et fixés auxdites languettes par vissage, préférentiellement à proximité de l'arête sur la moitié de la tranche du panneau du côté de l'arête.According to another advantageous embodiment of the invention, the metal sheet comprises at least two folded edges on the tongues, each forming an edge and fixed to said tongues by screwing, preferably near the edge on the half of the edge of the panel. on the side of the ridge.
Selon un encore autre mode avantageux de l'invention, les languettes ont une épaisseur mesurée dans le plan du panneau d'au moins 10 mm et ledit second matériau est tel qu'il permet d'y visser une vis auto taraudeuse. Pour ce faire, le second matériau est de densité supérieure, préférentiellement par un facteur supérieur ou égal à 5, à celle du premier matériau.According to another advantageous embodiment of the invention, the tongues have a thickness measured in the plane of the panel of at least 10 mm and said second material is such that it allows to screw a self-tapping screw. To do this, the second material is of higher density, preferably by a factor greater than or equal to 5, to that of the first material.
Selon un encore autre mode avantageux de l'invention, le panneau comprend au moins une cornière de renfort en tôle métallique épousant l'arête d'une des languettes et couvrant la face de la languette formant la tranche du panneau depuis ladite arête suffisamment que pour couvrir les trous destinés à coopérer par engagement avec des chevilles, ladite cornière étant préférentiellement fixée par vissage dans la languette.According to yet another advantageous embodiment of the invention, the panel comprises at least one reinforcing angle of sheet metal conforming to the edge of one of the tongues and covering the face of the tongue forming the edge of the panel from said edge sufficiently that for covering the holes intended to cooperate by engagement with dowels, said angle being preferably fixed by screwing in the tongue.
Selon un encore autre mode avantageux de l'invention, la face d'au moins une des languettes est pourvue de peinture intumescente, préférentiellement sur sa zone centrale, plus préférentiellement encore entre la cornière de renfort et le bord plié de la tôle métallique.According to another advantageous embodiment of the invention, the face of at least one of the tongues is provided with intumescent paint, preferably on its central zone, more preferably still between the reinforcing angle and the folded edge of the metal sheet.
Selon un encore autre mode avantageux de l'invention, le premier matériau est à base de verre cellulaire et/ou le second matériau est à base de silicate de magnésium renforcé.According to yet another advantageous embodiment of the invention, the first material is based on cellular glass and / or the second material is based on reinforced magnesium silicate.
Selon un encore autre mode avantageux de l'invention, le panneau comprend quatre languettes opposées deux à deux faites dans le second matériau isolant et rigide.According to yet another advantageous embodiment of the invention, the panel comprises four tongues opposite in pairs made in the second insulating and rigid material.
L'invention consiste également en une paroi isolante et résistante au feu comprenant au moins quatre panneaux tels que celui décrit ci-avant, lesdits panneaux étant disposés de manière jointive essentiellement dans le même plan et avec, pour chaque panneau, au moins deux bords disposés chacun en face d'un bord correspondant d'un autre desdits panneaux avec, pour au moins une paire de bords en face à face, au moins une, préférentiellement deux chevilles coopérant par engagement avec les trous correspondants de ladite paire de bords, la paroi comprenant également au moins une platine comprenant au moins deux trous et disposée à cheval le long de deux bords alignés de deux desdits panneaux, de part et d'autre de ladite paire de bords en face à face, les trous de la platine étant positionnés de manière à être traversés, chacun, par une des chevilles coopérant avec un trou d'un des deux bords alignés, à proximité de la jonction de ladite paire de bords en face à face.The invention also consists of an insulating wall and fire resistant comprising at least four panels such as that described above, said panels being arranged contiguously substantially in the same plane and with, for each panel, at least two edges arranged each facing a corresponding edge of another of said panels with, for at least one pair of face-to-face edges, at least one, preferably two pins cooperating by engagement with the corresponding holes of said pair of edges, the wall also comprising at least one plate comprising at least two holes and arranged astride two aligned edges of two of said panels, on either side of said pair of face-to-face edges, the holes of the plate being positioned each, through one of the pegs cooperating with a hole in one of the two aligned edges, near the junction of said pair of edges facing each other. face.
Selon un mode avantageux de l'invention, la platine comprend une partie en équerre destinée à être fixée préférentiellement par vissage à un mur ou une paroi en vis-à-vis des faces des panneaux opposées à celles recouvertes de la tôle métallique.According to an advantageous embodiment of the invention, the plate comprises an angled part intended to be fixed preferably by screwing to a wall or a wall opposite the faces of the panels opposite to those covered with the metal sheet.
Selon un autre mode avantageux de l'invention, la platine est généralement plane et comprend un trou à distance des faces des panneaux opposées à celles recouvertes de la tôle métallique, et destiné à coopérer avec des moyens de fixation suspendus à un plafond.According to another advantageous embodiment of the invention, the plate is generally flat and comprises a hole remote from the faces of the panels opposite to those covered with the metal sheet, and intended to cooperate with fastening means suspended from a ceiling.
Selon un encore autre mode avantageux de l'invention, un joint est disposé entre les deux bords repliés et en face à face des tôles métalliques de deux panneaux jointifs, à proximité de la surface extérieure desdites tôles, les vis de fixation desdits bords repliés étant à distance des arêtes correspondantes de manière à ménager la place nécessaire pour ledit joint.According to a still further advantageous embodiment of the invention, a seal is placed between the two folded edges and face to face of the metal sheets of two contiguous panels, close to the outer surface of said sheets, the fastening screws of said folded edges being remote from corresponding edges so as to provide the necessary space for said seal.

La tôle métallique 8 formant la face arrière du panneau 2 présente deux bords pliés à environ 90° à deux extrémités opposées de sorte à recouvrir partiellement les languettes ou bords opposés 12 du panneau 2. Des cornières métalliques 6 faites à partir de morceaux de tôle qui sont ensuite pliés sont disposés sur les arêtes de la face arrière du panneau 2 qui ne sont pas couvertes par la tôle 8. Ces cornières sont préférentiellement inégales de sorte à présenter un bord plus long sur la languette 4 que sur la face arrière du panneau 2. Le panneau comprend deux cornières, une de chaque côté opposé du panneau 2 où la tôle arrière 8 ne recouvre pas la tranche. Chaque cornière 6 s'étend sur essentiellement toute la longueur du bord du panneau 2. Elles sont fixées au moyen de vis 16, préférentiellement au moins une à proximité de chaque extrémité du bord à couvrir. Chaque cornière 6 comprend au moins un trou ou orifice 18 à proximité de chaque extrémité. Cet orifice est en correspondance avec un trou ou orifice 18 pratiqué dans la languette 4, servant ainsi de renfort de dudit orifice. L'orifice 18 va servir de moyen de liaison de deux panneaux adjacents.The
La face avant du panneau 2 est recouverte d'une tôle métallique 10 dont préférentiellement les quatre bords sont pliés à environ 90° de manière à recouvrir les quatre arêtes de ladite face et également une partie des languettes 4 et 12 formant les bords ou tranches du panneau 2. Ces bords pliés sont fixés aux languettes opposées 4 au moyen de vis 14.The front face of the

Le choix du matériau de l'âme isolante dépendra de différents paramètres, comme le prix de revient, la qualité d'isolation, les contraintes sanitaires comme le risque de prolifération microbienne et/ou encore la résistance aux hautes températures. L'âme isolante 22 sera typiquement en Foamglass® T4, à savoir du verre cellulaire alumino-silicaté. Ce matériau présente une très bonne stabilité dimensionnelle, une densité de l'ordre de 0.12, une plage de température d'emploi allant de -260°C à +430°C et une incombustibilité classée M0 selon la norme française NF P 92-507. L'épaisseur sera comprise entre 40 et 160 mm, plus particulièrement entre 40 et 100 mm, typiquement de l'ordre de 60 mm.The choice of the material of the insulating core will depend on various parameters, such as the cost price, the quality of insulation, health constraints such as the risk of microbial proliferation and / or resistance to high temperatures. The insulating
La couche mince 20 et les languettes 4 et 12 seront en matériau isolant incombustible et présentant une certaine résistance mécanique, comme par exemple en FIBRODICE MS à base de silicate de magnésium renforcé. Les qualités mécaniques de ce matériau lui permettent d'être poncé, scié, percé, cloués, vissés et/ou collés. Il présente une densité de l'ordre de 1 (1.050 ± 0.1), un module d'élasticité compris entre 5210 et 7845 N/mm2 et une résistance à la flexion comprise entre 12.1 et 17.1 N/mm2. Les silicates sont des minéraux dont le squelette est essentiellement formé par des tétraèdres de Silicium et d'Oxygène additionnés d'aluminium, magnésium, fer, calcium, potassium, sodium et autres éléments. Les fibres de verre à usage spécial sont des microfibres de silicates vitreuses artificielles à orientation aléatoire et dont le pourcentage pondéral d'oxydes alcalins et d'oxydes alcalino-terreux est supérieur à 18 %. Le diamètre de ces fibres est compris entre 0,01 et 3 microns. Il existe plusieurs types de fibres à usage spécial, classées en fonction de la composition chimique du verre : E, 475, 753, 481... Les plus étudiées sont les microfibres de verre E et 475. A la différence des fibres d'amiante, elles ne peuvent pas se scinder en fibrilles de diamètres inférieurs mais se coupent transversalement. A l'exception des microfibres de verre 481, elles sont très peu solubles dans les milieux biologiques et présentent une biopersistance élevée.The
Il est à noter que la présence de la couche mince 20 entre l'âme isolante et la tôle métallique avant 10 n'est pas obligatoire. En effet, bien que cette couche aie un rôle de renforcement mécanique et de protection de l'âme isolante, sa présence reste optionnelle en fonction, notamment, des contraintes thermiques et mécaniques du panneau ainsi que du choix du matériau pour l'âme isolante. Il en va de même pour les languettes 12 (
La face avant de la couche mince 20 est recouverte d'une tôle métallique 10. Comme déjà expliqué en relation avec la
La face arrière du panneau, plus particulièrement la face arrière de l'âme 22 est recouverte d'une tôle métallique 8. Les bords de celle-ci s'arête environ au niveau des arêtes des languettes 4, de manière à pouvoir être recouvertes d'une cornière métallique 6 de renfort.The rear face of the panel, more particularly the rear face of the
La tôle métallique de la face avant 10 présente typiquement une épaisseur de l'ordre de 1 mm. D'autres épaisseurs sont bien sûr possibles en fonction des propriétés mécaniques de la tôle et des contraintes auxquelles le panneau est soumis. L'épaisseur va typiquement varier entre 0.5 mm et 2 mm, préférentiellement entre 0.6 et 1.2 mm. La tôle 10 a pour rôle d'assurer une tenue mécanique du panneau (tenue de forme et résistance à l'enfoncement lors de contact avec des objets), une finition esthétique, un écran de protection aux flammes et une finition compatible avec les normes sanitaires en vigueur notamment pour le stockage d'aliments. La tôle peut être en Aluzinc® qui est un produit plat carbone allié composé de 55% d'aluminium, de 43,4% de zinc et 1,6% de silicium. L'acier est revêtu en continu sur une ligne de galvanisation au trempé. L'excellente résistance à la corrosion de l'Aluzinc® résulte des caractéristiques de ses deux composants métalliques : l'aluminium présent à la surface du revêtement agit comme une barrière aux agents de corrosion, le zinc protège l'acier par effet «sacrificiel». L'Aluzinc® présente un aspect esthétique dû à son fleurage caractéristique de couleur argent. La surface du dépôt métallique est protégée par une fine couche d'oxydes d'aluminium assurant la pérennité de son éclat.The metal sheet of the
La tôle métallique arrière 8 est typiquement plus mince car elle vient en complément de la tôle avant 10. Elle assure un renforcement supplémentaire du panneau mais surtout ferme la face arrière afin de parer à toute prolifération microbienne vers l'intérieur du panneau. Il est à noter que cette tôle arrière n'est pas indispensable d'un point de vue tenue mécanique du panneau, ni d'un point de vue qualité d'isolation et ni d'un point de vue de protection contre le feu. En fonction des applications, celle tôle pourra être évitée, laissant libre la face arrière de l'âme en matériau isolant ou laissant la place à une couverture de finition d'un autre type comme par exemple un film souple. La tôle métallique 8 présente typiquement une épaisseur de l'ordre de 0.5 mm. Elle pourra cependant varier entre 0.2 et 1 mm en fonction du matériau et des propriétés mécanique de la tôle et également en fonction de l'application du panneau. La tôle 8 est typiquement une tôle en acier galvanisée. Elle pourra être en Aluzinc® comme la tôle avant 10 mais il est clair que les qualités esthétiques de l'Aluzinc® ne seront pas utiles compte tenu du fait qu'elle constitue la face arrière du panneau qui est normalement destinée à être non visible.The

Un cordon d'étanchéité 28 est appliqué entre les bords repliés des tôles avant 10 des deux panneaux superposés. Il assure une étanchéité de l'habillage ou vêture. Il est idéalement en matériau résistant aux hautes températures, comme, par exemple, le mastic DOW CORNING® Firestop 700 résistant au feu.A sealing
Une couche de peinture intumescente (non représentée) est appliquée sur les chants des panneaux, c'est-à-dire sur les faces extérieures des languettes de manière à assurer une étanchéité aux gaz et aux flammes en cas d'incendie. En effet, en cas d'incendie, le cordon d'étanchéité 28 bien qu'apte à résister un certain temps, pourra céder dans la mesure où les couches de peinture intumescente auront pu gonfler et se rejoindre pour obstruer le passage entre les bords des deux panneaux superposés, assurant ainsi une étanchéité renforcée en cas d'incendie.A layer of intumescent paint (not shown) is applied to the edges of the panels, that is to say on the outer faces of the tongues so as to provide a seal against gases and flames in case of fire. Indeed, in case of fire, the sealing
