Description

La présente invention a pour objet un panneau destiné à être appliqué sur une face d'une paroi à protéger contre le feu.The present invention relates to a panel intended to be applied to a face of a wall to be protected against fire.

On a déjà proposé des panneaux ou des structures aptes à résister au feu. Toutefois les panneaux ou structures jusqu'à présent proposés ne permettaient pas d'obtenir des résistances au feu suffisantes pour la paroi à protéger. De tels panneaux étaient lourds et donc rendaient leur utilisation impossible sur des portes. De plus l'installation de ceux-ci était coûteuse. De ce fait, l'homme du métier a toujours privilégié l'utilisation de parois ou portes résistantes au feu, plutôt que d'essayer de leur assurer une protection en y appliquant un revêtement applicable sous forme liquide ou de pâte.We have already proposed panels or structures able to withstand fire. However, the panels or structures heretofore proposed did not make it possible to obtain sufficient fire resistance for the wall to be protected. Such panels were heavy and therefore made their use impossible on doors. In addition, the installation of these was expensive. Therefore, the skilled person has always favored the use of fire-resistant walls or doors, rather than trying to provide protection by applying a coating applicable in liquid or paste form.

Le document DE 196 25 643 A1 décrit un panneau pour la protection au moins contre le feu d'une face d'une paroi, ledit panneau comprenant une tôle en acier d'épaisseur minimale d'au moins 0,5mm, ladite tôle de forme rectangulaire présentant quatre bords pliés avec chacun une hauteur d'au moins 5mm, de manière à former sensiblement une cuvette avec un fond délimité par les bords pliés, une couche en matériau isolant définissant un corps sensiblement parallélépipédique présentant une première face sensiblement rectangulaire, une deuxième face sensiblement rectangulaire opposée à ladite première face, quatre faces latérales s'étendant entre lesdites première et deuxième faces sensiblement rectangulaires ou carrées, la première face de ladite couche prenant appui sur le fond de la cuvette.The document DE 196 25 643 A1 discloses a panel for the at least one fire protection of a face of a wall, said panel comprising a steel sheet having a thickness of at least 0.5 mm, said rectangular sheet having four folded edges with each a height of at least 5 mm, so as to form substantially a bowl with a bottom delimited by the folded edges, a layer of insulating material defining a substantially parallelepiped body having a first substantially rectangular face, a second substantially rectangular face opposite said first face, four lateral faces extending between said first and second substantially rectangular or square faces, the first face of said layer bearing on the bottom of the bowl.

Le but de l'invention est d'avoir un panneau de poids acceptable apte à être attaché rapidement, facilement et sans avoir recours à des techniques compliquées, sur la paroi à protéger, de préférence sans devoir percer un ou des orifices dans la paroi, de manière à ne pas toucher à la structure même de la paroi, ou en ne perçant qu'un nombre limité de trous dans la paroi.The object of the invention is to have an acceptable weight panel capable of being attached quickly, easily and without the use of complicated techniques, to the wall to be protected, preferably without having to drill one or more holes in the wall, so as not to touch the very structure of the wall, or by piercing only a limited number of holes in the wall.

Le but de l'invention est également un panneau de protection au feu qui une fois installé sur une paroi ne peut pas être retiré de la paroi par un homme non du métier. Le panneau selon l'invention comporte une protection contre les agressions, ce qui permet par inspection visuelle de déterminer si un panneau a été endommagé ou non et doit ou non être remplacé.The object of the invention is also a fire protection panel which once installed on a wall can not be removed from the wall by a non-skilled person. The panel according to the invention comprises a protection against aggression, which allows visual inspection to determine whether a panel has been damaged or not and must or not be replaced.

Les panneaux selon l'invention seront fabriqués en usine et auront avantageusement une forme générale parallèlipipédique de taille identique ou différente ou variable, mais de préférence de même épaisseur. Les panneaux selon l'invention pourront être placés les uns à côté d'autres pour assurer une protection de paroi de grande dimension.The panels according to the invention will be manufactured in the factory and will advantageously have a parallelepiped general shape of identical size or different or variable, but preferably of the same thickness. The panels according to the invention may be placed next to each other to provide a large wall protection.

Vu le poids limité des panneaux selon l'invention, les panneaux selon l'invention peuvent être vendus sous forme de kit destiné à la protection d'une paroi, en particulier d'une porte. Dans le cas de kit, le panneau peut être livré en pièces détachées faciles à assembler entre elles.Given the limited weight of the panels according to the invention, the panels according to the invention can be sold in the form of a kit for protecting a wall, in particular a door. In the case of kit, the panel can be delivered in spare parts easy to assemble them.

This panel P for at least fire protection of a face of a wall S, in particular a moving wall, more specifically a door or flap, said panel being intended to be attached to said face to be protected, comprises:
  • a steel sheet 1 (for example galvanized or stainless steel) with a minimum thickness of at least 0.5 mm, in particular at least 1 mm (for example from 1 mm to 5 mm, in particular from 1 mm to 3 mm, by example of about 2mm), said sheet of substantially rectangular shape having four folded edges 10,11,12,13, so as to form substantially a bowl 2 with a bottom 14 defined by the folded edges, each of said folded edges 10,11 , 12,13 extending advantageously in a plane substantially perpendicular to the plane in which said bottom 14 extends, said folded edges advantageously have a height of at least 5 mm, in particular a height corresponding to between 20 and 50% of the thickness of the layer based on calcium silicate 3; said folded edges 10, 11, 12, 13, 14 preferably having rounded corners, said folded edges, although able to be independent of each other, are preferably welded to each other so as to define a liquid-tight bowl near its bottom 14 (the Figure 9A shows in plan a sheet 1 with four rounded corners and with four cutting lines of length slightly greater than once the height of the folded edges 10,11,12,13, for example approximately equal to one time the height of the folded edges plus The thickness of the sheet 1. The cutting lines are advantageously terminated along the edges of the sheet 1 by a rounded. With the embodiment of the Figure 9A it is possible to form edges 10,12 with tabs 10E, 12E extreme which when folded at 90 ° with respect to the plane of the edges are able to bear and / or be welded on the folded edges 11 or 13 (the Figure 9B shows a sheet 1 with substantially square or rectangular cuts - preferably substantially square - at the four corners, so as to define edges advantageously with rounded corners); said folded edges being advantageously perforated or pre-perforated (holes 15) to form a passage for fastener rods 8;
  • a non-flexible layer 3 based on calcium silicate (advantageously porous) with a binder hardened by autoclaving (said layer advantageously comprising more than 50% by weight of calcium silicate, in particular more than 75% by weight of calcium silicate) said layer 3 having a thickness of at least 20 mm (for example from 20 mm to 50 mm, in particular from 25 mm to 40 mm), said non-flexible layer (advantageously having a density of less than 500 kg / m 3 , advantageously from 150 to 350 kg / m 3 ) defining a substantially parallelepipedal body having a first substantially rectangular face 30, a second substantially rectangular face 31 opposite said first face 30, four lateral faces 32, 33, 34, 35 extending between said first and second faces 30,31 substantially rectangular, the first face 30 of said layer based on calcium silicate bearing on the bottom 14 of the bowl 2 advantageously with interposition one or means 4 providing one or more open passages for the flow of fluid between the bottom and said first face (said means 4 are advantageously zones or lines of glue separated from each other ensuring attachment in separate zones between the face 30 of the layer and the bottom 14 of the bowl 2; said means 4 preferably providing a gap between the bottom 14 of the bowl and the face 30 of less than 1 mm, in particular from 50 .mu.m to 750 .mu.m, more specifically from 100 .mu.m to 500 .mu.m);

La bande flexible 9 comprend une structure centrale de section sensiblement rectangulaire avec un rapport épaisseur sur largueur compris entre 1 : 15 et 3 : 10, en particulier entre 1 : 15 et 1 : 5.The flexible band 9 comprises a central structure of substantially rectangular section with a thickness to width ratio between 1: 15 and 3: 10, in particular between 1: 15 and 1: 5.

La bande flexible 9 a une partie extrême qui couvre une autre partie de la bande, ceci de manière à assurer un joint sensiblement continu s'étendant entre les bords pliés de la tôle 1 et les premiers plats 71 des cornières 7. Les moyens de fixation 8 ont des tiges 80 avantageusement filetées qui chacune s'étendent depuis l'extérieur vers l'intérieur du panneau à travers les bords pliés de la tôle 1, à travers la bande flexible 9, à travers le plat 71 d'une cornière 7 et dans la couche 3. La tige filetée s'étend parallèllement au plan de la face 30, par exemple sur une profondeur de l'ordre de 20 à 50 mm dans la couche 3. La tige filetée est associée à une tête prenant appui sur un bord plié 10,11,12,13 de la tôle 1 et assure une mise sous compression de la bande flexible 9 entre un bord plié et une cornière et donc un bon maintien en place de la bande flexible 9.The flexible band 9 has an end part which covers another part of the band, this so as to ensure a substantially continuous seal extending between the folded edges of the sheet 1 and the first plates 71 of the angles 7. The fixing means 8 have preferably threaded rods 80 which each extend from the outside to the inside of the panel through the folded edges of the sheet 1, through the flexible strip 9, through the plate 71 of an angle 7 and in layer 3. The threaded rod extends parallel to the plane of the face 30, for example to a depth of the order of 20 to 50 mm in the layer 3. The threaded rod is associated with a head bearing on a folded edge 10,11,12, 13 of the sheet 1 and ensures a compression of the flexible band 9 between a folded edge and an angle and thus a good retention in place of the flexible strip 9.

Comme il ressort de la figure 8, le plat 71 de la cornière 7 a une extrémité libre qui est distante du fond 14 de la cuvette, formant ainsi une goulotte 40 rempli d'air. Les deuxièmes plats 72 des cornières 7 présentent chacun une face extérieure non tournée vers la couche 3 à base de silicate de calcium, lesdites faces extérieures s'étendant sensiblement dans un même plan parallèle au plan du fond 14 de la cuvette formée par la tôle 1. La deuxième face 31 de la couche 3 à base de silicate de calcium se situe entre ledit plan des deuxièmes plats 72 parallèle au plan du fond 14 de la cuvette et ledit plan du fond 14 de la cuvette, mais au moins sous ledit plan desdites faces extérieures des deuxièmes plats 72. La deuxième face 31 de la couche 3 à base de silicate de calcium se situe au moins 1 mm, avantageusement de 1 à 3mm sous ledit plan des faces extérieures des deuxièmes plats. Ceci permet de créer un creux entre la face 31 de la couche 3 et la paroi à protéger, creux adapté pour recevoir des zones, lignes ou points de colle, avantageusement distants ou séparés les uns des autres.As is apparent from the figure 8 , the plate 71 of the bracket 7 has a free end which is distant from the bottom 14 of the bowl, thus forming a chute 40 filled with air. The second plates 72 of the angles 7 each have an outer face not facing the layer 3 based on calcium silicate, said outer faces extending substantially in the same plane parallel to the plane of the bottom 14 of the bowl formed by the sheet 1 The second face 31 of the calcium silicate-based layer 3 is located between said plane of the second plates 72 parallel to the plane of the bottom 14 of the bowl and said bottom plane 14 of the bowl, but at least under said plane of said outer faces of the second plates 72. The second face 31 of the layer 3 based on calcium silicate is at least 1 mm, preferably 1 to 3 mm under said plane of the outer faces of the second plates. This makes it possible to create a hollow between the face 31 of the layer 3 and the wall to be protected, hollow adapted to receive zones, lines or points of glue, advantageously distant or separated from each other.

La couche à base de silicate de calcium et/ou la structure centrale de la/les bandes flexibles est une couche à base de particules de silicate de calcium et/ou de sodium sphériques ou sensiblement sphériques creuses.The calcium silicate-based layer and / or the central structure of the flexible band (s) is a layer based on spherical or substantially hollow spherical calcium and / or sodium silicate particles.

Les particules de silicate de calcium et/ou de sodium forment un réseau ou une structure tri dimensionnelle.The calcium silicate and / or sodium particles form a three-dimensional network or structure.

Dans la forme de réalisation, la deuxième face 31 de la couche à base de silicate de calcium n'est pas recouverte par une couche continue imperméable au gaz, mais est de préférence recouverte par une couche ou film ou voile perméable au gaz et résistant à des températures supérieures à 300°C pendant au moins 30minutes, de préférence résistant à des températures supérieures à 500°C pendant au moins 30 minutes, de préférence pendant au moins 60 minutes. Dans une forme de réalisation possible la couche à base de silicate de calicum est enveloppée dans une enveloppe réalisée au moyen d'une couche ou film ou voile perméable au gaz et résistant à des températures supérieures à 300°C pendant au moins 30minutes, de préférence résistant à des températures supérieures à 500°C pendant au moins 30 minutes, de préférence pendant au moins 60 minutesIn the embodiment, the second face 31 of the calcium silicate layer is not covered by a gas-impermeable continuous layer, but is preferably covered by a gas-permeable layer or film or web. resistant to temperatures above 300 ° C for at least 30 minutes, preferably resistant to temperatures above 500 ° C for at least 30 minutes, preferably for at least 60 minutes. In one possible embodiment, the calicum silicate-based layer is wrapped in a jacket made of a gas-permeable layer or film or web resistant to temperatures above 300 ° C for at least 30 minutes, preferably resistant to temperatures above 500 ° C for at least 30 minutes, preferably for at least 60 minutes

La fixation du panneau peut être assurée uniquement au moyen de colle, mais peut également être assurée au moyen de vis 18. Par exemple, les deuxièmes plats des cornières sont dans une première étape attachés à la paroi à protéger, avant de fixer la couche 3 avec ou sans la tôle 1, et avant placement de la bande flexible 7. Dans un tel cas, les cornières peuvent être soudées entre elles pour former un cadre dont les premiers plats 71 sont avantageusement associés à la bande flexible 7. L'utilisation d'un tel cadre rend plus facile le placement de la couche 3 à base de silicate de calcium.The fixing of the panel can be ensured only by means of glue, but can also be ensured by means of screws 18. For example, the second flats of the angles are in a first step attached to the wall to be protected, before fixing the layer 3 with or without the sheet 1, and before placement of the flexible strip 7. In such a case, the angles can be welded together to form a frame whose first plates 71 are advantageously associated with the flexible strip 7. The use of such a frame makes it easier to place the layer 3 based on calcium silicate.

Pour éviter un contact direct des deuxièmes plats 72 des cornières 7 sur la paroi à protéger ou sur la porte à protéger, il est avantageux de placer un voile poreux et/ou ajourée ou une couche poreuse et/ou ajourée (par exemple mat, tissu, etc.) de faible épaisseur (par exemple de moins de 1mm d'épaisseur, avantageusement de moins de 500µm d'épaisseur) entre les deuxièmes plats 72 et la paroi à protéger. Ce voile 80 peut ne recouvrir que les deuxièmes plats, mais de préférence recouvre au moins sensiblement tous les deuxièmes plats des cornières et au moins la partie de la deuxième face de la couche 3 s'étendant entre les cornières 7. Ce voile poreux assure d'une part une protection de la couche 3, mais également permet un passage contrôlé d'air ou de gaz entre d'une part la paroi et d'autre part les cornières et la bande flexible 7.To avoid direct contact of the second plates 72 of the brackets 7 on the wall to be protected or on the door to be protected, it is advantageous to place a porous and / or perforated web or a porous and / or perforated layer (for example, mat, fabric , etc.) of small thickness (for example less than 1mm thick, preferably less than 500μm thick) between the second plates 72 and the wall to be protected. This web 80 may cover only the second plates, but preferably covers at least substantially all the second plates angles and at least the portion of the second face of the layer 3 extending between the angles 7. This porous web ensures that on the one hand a protection of the layer 3, but also allows a controlled passage of air or gas between the wall on the one hand and the angles and the flexible strip 7 on the other hand.

Ce voile ou mat poreux et/ou ajouré permet avantageusment malgré tout le passage de colle de manière à assurer une fixation de la couche 3 sur la paroi à protéger.This veil or matte porous and / or perforated advantageously despite the passage of glue so as to ensure a fixation of the layer 3 on the wall to be protected.

La figure 3 montre en perspective un détail d'un coin d'un panneau selon l'invention. Dans cette forme de réalisation, les bords pliés 10,11 sont écartés l'un de l'autre pour former une fente 100, tandis que les cornières 7 sont distantes l'une de l'autre, de manière à former un passage 101 entre les plats des cornières 7.The figure 3 shows in perspective a detail of a corner of a panel according to the invention. In this embodiment, the folded edges 10, 11 are spaced from each other to form a slot 100, while the brackets 7 are spaced apart from each other so as to form a passage 101 between the flat angles 7.

La figure 4 montre une porte P, par exemple en bois, dont une face est associée à un panneau selon l'invention du type représenté à la figure 1, si ce n'est que les cornières 7 sont biseautées à leurs extrémités libres et forment un cadre rectangulaire. Le cadre rectantulaire. Ce cadre est avantageusement prémuni d'une bande flexible 9 recouvrant les plats 71 des quatre cornières 7, de manière à former un revêtement continu. Cette bande flexible est par exemple attachée au moyen de colle (en particulier du type silicone). Dans cette forme de réalisation, on fixe dans un premier temps le cadre formé par les cornières 7 sur la face de porte à protéger au moyen de vis 18. Après avoir appliqué des zones de colle silicone séparées l'une de l'autre sur la paroi à protéger et/ou sur la deuxième face 31 de la couche 3, on place la couche 3 dans le creux formé par le cadre.The figure 4 shows a door P, for example of wood, one face of which is associated with a panel according to the invention of the type shown in FIG. figure 1 , except that the angles 7 are bevelled at their free ends and form a rectangular frame. The rectantular frame. This frame is advantageously provided with a flexible band 9 covering the plates 71 of the four angles 7, so as to form a continuous coating. This flexible band is for example attached by means of glue (in particular of the silicone type). In this embodiment, the frame formed by the angles 7 on the door face to be protected by means of screws 18 is first fixed. After having applied silicone adhesive zones separated from each other on the wall to be protected and / or on the second face 31 of the layer 3, the layer 3 is placed in the hollow formed by the frame.

Si les plats 71 des cornières n'ont pas été prémunis d'un revêtement continu avec la bande flexible 9, on associe lesdits plats à une bande flexible 9.If the plates 71 of the angles have not been protected from a continuous coating with the flexible band 9, said plates are associated with a flexible band 9.

On place ensuite la tôle 1 avec les bords pliés 10,11,12,13, qui forme une sorte de couvercle protégeant la couche 3 à base de silicate de calcium.The sheet 1 is then placed with the folded edges 10, 11, 12, 13, which forms a kind of cover protecting the layer 3 based on calcium silicate.

Avantageusement avant de placer ledit couvercle et de le fixer au moyen des vis 8, des zones de colle silicone sont appliquées sur le fond 14 et/ou sur la face 30 de la couche 3 à base de silicate de calcium.Advantageously, before placing said cover and securing it by means of the screws 8, areas of silicone adhesive are applied to the bottom 14 and / or to the face 30 of the layer 3 based on calcium silicate.

La fixation du couvercle est ainsi assurée par des zones de colle et par des vis 8.The fixing of the lid is thus ensured by adhesive zones and by screws 8.

La figure 5 est une vue avant d'une paroi mobile de grande dimension associée d'une série de panneaux P suivant l'invention. Entre les différents panneaux une bande flexible 9A est placée. Avantageusement, la ou les bandes flexibles sont fixées au moyen de points de colle. Cette bande flexible est du type similaire à la bande flexible 9. Cette bande flexibleThe figure 5 is a front view of a movable wall of large size associated with a series of panels P according to the invention.

La figure 7 est une vue en coupe d'un détail d'un panneau suivant l'invention.The figure 7 is a sectional view of a detail of a panel according to the invention.

Ce panneau présente un orifice sensiblement cylindrique 16 s'étendant dans la couche 3 à base de silicate de calcium et dans la tôle 1. Cet orifice est obturé par un bouchon 60 monté rotatif dans ledit orifice. Ce bouchon comprend un disque 61 destiné à s'étendre le long de la tôle 1, ledit disque étant attaché à un corps cylindrique 62 (avantageusement à base de silicate de calcium) adapté pour épouser la forme du trou cylindrique. Le corps comporte des évidements axiaux pour recevoir des manchons 63, 64 avec par exemple un évidement central carré ou hexagonal. Les manchons sont par exemples attachés au corps 62 par vissage. Le manchon 64 est par exemple solidaire du disque 61. Lorsque le bouchon 60 n'est pas utilisé pour assurer une liaison avec un système d'ouverture de porte (poignée associée à un manchon, et tige de commande d'ouverture associée à l'autre manchon), les manchons sont obturés par exemple au moyen d'un couvercle amovible (par exemple attaché par clipsage).This panel has a substantially cylindrical orifice 16 extending in the layer 3 based on calcium silicate and in the sheet 1. This orifice is closed by a plug 60 rotatably mounted in said orifice. This cap comprises a disc 61 intended to extend along the sheet 1, said disc being attached to a cylindrical body 62 (preferably based on calcium silicate) adapted to match the shape of the cylindrical hole. The body has axial recesses for receiving sleeves 63, 64 with for example a central square or hexagonal recess. The sleeves are for example attached to the body 62 by screwing. The sleeve 64 is for example integral with the disk 61. When the cap 60 is not used to ensure a connection with a door opening system (handle associated with a sleeve, and opening control rod associated with the other sleeve), the sleeves are closed for example by means of a removable cover (for example attached by clipping).

Des tests réalisés avec un panneau selon l'invention avec une couche à base de silicate de calcium de 30mm d'épaisseur attaché sur une porte en bois ont démontré que la porte en bois avait une meilleure résistance au feu, que la face de la porte non soumise à l'impact de la flamme restait à une température de moins de 60°C pendant au moins 30 minutes, que les joints élastomères J sur lesquels prennent appui les bords de la porte ne subissaient sensiblement aucune dégradation après plus de 15 minutes, que la tôle 1 permettait une bonne répartition de la chaleur vers la couche 3 à base de silicate de calcium, que le panneau assurait une bonne isolation au bruit, en particulier au bruit de la flamme, que le panneau n'avait pas tendance à vouloir se décoller de la porte malgré l'application de la flamme, et que la gaine flexible 9 avait tendance à gonfler formant alors un joint protégant encore les joints élastomères J.Tests carried out with a panel according to the invention with a layer of 30 mm thick calcium silicate attached to a wooden door have shown that the wooden door had a better fire resistance than the door face. not subject to the impact of the flame remained at a temperature of less than 60 ° C for at least 30 minutes, that the elastomeric J seals on which the edges of the door rest did not undergo substantially any deterioration after more than 15 minutes, that the sheet 1 allowed a good distribution of the heat towards the layer 3 based on calcium silicate, that the panel provided a good insulation to the noise, in particular to the noise of the flame, that the panel n ' was not likely to want to take off from the door despite the application of the flame, and that the flexible sheath 9 had a tendency to swell then forming a seal still protecting the elastomeric J joints.

Le panneau et/ou la paroi à protéger peuvent également être associés à un ou des équipements divers, tels que oculus, judas, oeilleton, grille, par exemple grille de ventilation, vitre, etc..The panel and / or the wall to be protected may also be associated with one or more equipment, such as oculus, peephole, eyecup, grid, for example ventilation grid, window, etc.
