Description

L'invention concerne un faux plafond, notamment pour hall d'exposition.The invention relates to a false ceiling, in particular for an exhibition hall.

Les techniques de réalisation des faux plafonds en textile, généralement appelés "vélums", notamment dans les halls d'exposition, présentent une grande importance.The techniques for making false ceilings in textiles, generally called "velums", especially in exhibition halls, are of great importance.

En effet, les halls sont habituellement très hauts pour pouvoir accueillir les présentations les plus volumineuses mais lorsqu'ils sont utilisés pour des expositions d'objets plus réduits, il est nécessaire d'établir un faux plafond intermédiaire qui réduit la hauteur visible en cachant les éléments fixes de structure. On améliore alors grandement l'esthétique générale de l'exposition en créant un volume en harmonie avec l'argument de l'exposition et la taille des produits qui y sont disposés.Indeed, the halls are usually very high to be able to accommodate the most voluminous presentations but when they are used for exhibitions of smaller objects, it is necessary to establish an intermediate false ceiling which reduces the visible height by hiding the fixed structural elements. We then greatly improve the general aesthetics of the exhibition by creating a volume in harmony with the argument of the exhibition and the size of the products placed there.

Pour y parvenir, plusieurs techniques ont été employées jusqu'à présent.To achieve this, several techniques have been used so far.

La technique la plus ancienne consiste à mettre en oeuvre des vélums en tissu de coton léger ignifugé, qui sont tendus horizontalement sur de grandes surfaces. Ils sont cependant maintenant très peu employés car la plupart des bâtiments sont équipés de trappes de désenfumage et/ou d'un réseau d'extincteurs automatiques d'arrosage. Or, pour que ces installations fonctionnent, il est indispensable que l'éventuel foyer d'un début d'incendie impressionne la tête d'extincteur fixée au plafond à la verticale approximative de ce foyer, cette action étant déclenchée par la colonne ascendante des gaz chauds émanant du foyer, ce foyer étant ensuite éteint par les jets d'eau dirigés de haut en bas issus des extincteurs automatiques. Il s'ensuit, pour que le système d'extinction fonctionne, que les gaz chauds ne soient pas arrêtés ou déviés par un obstacle horizontal comme un vélum en tissu tendu.The oldest technique consists in using vellums in light flame-retardant cotton fabric, which are stretched horizontally over large areas. However, they are now very little used because most buildings are equipped with smoke extraction hatches and / or a network of automatic sprinkler systems. So that these installations work, it is essential that the possible hearth of a beginning of fire impresses the head of extinguisher fixed to the ceiling with the approximate vertical of this hearth, this action being started by the ascending column of the hot gases coming from the hearth , this hearth then being extinguished by the water jets directed from top to bottom from the automatic fire extinguishers. It follows, for the extinguishing system to work, that the hot gases are not stopped or deflected by a horizontal obstacle such as a stretched fabric canopy.

Depuis la généralisation de l'équipement des bâtiments d'exposition par des extincteurs automatiques, les vélums horizontaux habituels sont donc devenus inemployables.Since the generalization of the equipment of exhibition buildings with automatic fire extinguishers, the usual horizontal canopies have therefore become unusable.

Le problème de l'évacuation des fumées, même si le bâtiment n'est pas équipé d'un réseau automatique d'arrosage, est identique. Il est, du reste, extrêmement important pour la sauvegarde du public, que les fumées soient évacuées car, en cas d'incendie, en plus d'être asphyxiantes, elles masquent la vue des issues de secours.The problem of smoke evacuation, even if the building is not equipped with an automatic sprinkler system, is identical. It is, moreover, extremely important for the protection of the public, that the fumes are evacuated because, in the event of fire, in addition to being asphyxiating, they mask the view of the emergency exits.

Pour résoudre ces contraintes techniques extrêmement importantes et cependant disposer de faux plafonds, on a eu recours à plusieurs autres techniques.To resolve these extremely important technical constraints and yet have false ceilings, several other techniques were used.

L'une de ces techniques consiste à mettre en oeuvre des textiles résistant au feu tendus horizontalement et dont le tissage présente des mailles suffisamment larges, à la manière d'un filet, pour permettre le passage ascendant des gaz chauds et descendant des jets d'eau des extincteurs.One of these techniques consists in using fire-resistant textiles stretched horizontally and the weaving of which has sufficiently large meshes, in the manner of a net, to allow the upward passage of hot gases and downward of the jets. water from fire extinguishers.

Cependant, ces mailles doivent également être suffisamment serrées pour remplir la fonction essentielle du faux plafond, qui est de dissimuler les superstructures, si bien que ce type de faux plafond est pratiquement inefficace car les deux conditions ci-dessus sont incompatibles.However, these meshes must also be sufficiently tight to fulfill the essential function of the false ceiling, which is to conceal the superstructures, so that this type of false ceiling is practically ineffective because the two conditions above are incompatible.

Une autre technique a consisté à mettre en oeuvre des bandes de matériau généralement réalisées en non-tissé du genre papier, qui sont pliées par exemple en zigzag et ignifugées. Ces bandes sont suspendues verticalement afin de former, par exemple, une structure en nids d'abeilles. Ces faux plafonds rendent de grands services car ils sont esthétiques et parfaitement conformes avec les principes de sécurité. En effet, ils ne présentent aucun obstacle à l'ascension des gaz chauds ni à l'aspersion par les jets d'eau. Cependant, leur principe même crée un faux plafond non uni dont l'esthétique ne s'accorde pas avec tous les matériels exposés.Another technique consisted in using strips of material generally made of nonwoven of the paper type, which are folded for example in a zigzag and flame retardant. These strips are hung vertically to form, for example, a honeycomb structure. These false ceilings are of great service because they are aesthetic and perfectly comply with the safety principles. Indeed, they do not present any obstacle to the rise of hot gases nor to the spraying by the water jets. However, their very principle creates a non-united false ceiling whose aesthetic does not agree with all the materials on display.

Une autre technique consiste également à tendre horizontalement des feuilles de matériau non tissé, qui comportent des clapets prédécoupés, pouvant laisser passer les gaz chauds et les jets d'eau. Cette technique permet, bien entendu, de réaliser des plafonds d'aspect horizontal, unis, mais avec de nombreux défauts de surface qui en limitent considérablement l'emploi. Ils sont, de plus, d'une pose délicate et onéreuse.Another technique also consists in stretching horizontally sheets of non-woven material, which include pre-cut valves, which can allow hot gases and water jets to pass. This technique makes it possible, of course, to produce ceilings with a horizontal, plain appearance, but with numerous surface defects which considerably limit their use. They are, moreover, of a delicate and expensive pose.

Vis-à-vis de ces techniques connues, la présente invention concerne un faux plafond notamment pour hall d'exposition, caractérisé en ce qu'il se compose de feuilles en matériau souple reliées les unes aux autres par un moyen fusible.With respect to these known techniques, the present invention relates to a false ceiling, in particular for an exhibition hall, characterized in that it consists of sheets of flexible material connected to each other by a fusible means.

Suivant une autre caractéristique de l'invention, le moyen fusible agit par collage de la périphérie des feuilles, afin de les maintenir assemblés.According to another characteristic of the invention, the fusible means acts by bonding the periphery of the sheets, in order to keep them assembled.

Suivant une autre caractéristique de l'invention, le moyen fusible est réalisé sous la forme d'un fil assurant la jonction de la périphérie des feuilles.According to another characteristic of the invention, the fusible means is produced in the form of a wire ensuring the junction of the periphery of the sheets.

Suivant une autre caractéristique de l'invention, le matériau souple constitue un article textile réalisé en tout ou partie sous la forme d'un article à mailles, des rangées de mailles de cet article étant réalisées à l'aide du fil fusible.According to another characteristic of the invention, the flexible material constitutes a textile article produced in whole or in part in the form of a mesh article, rows of stitches of this article being produced using the fusible wire.

La présente invention a en conséquence pour but la réalisation d'un faux plafond, qui soit esthétique, dans la mesure où il présente une surface horizontale et unie, qui soit d'une pose et d'une dépose rapides dans la mesure où il peut être réalisé en surfaces de grandes dimensions, et qui respecte les conditions de sécurité dans la mesure où dès qu'un foyer d'incendie s'est déclaré, il permet l'évacuation des fumées et le déclenchement des têtes du réseau d'arrosage automatique.The present invention therefore aims to achieve a false ceiling, which is aesthetic, to the extent that it has a horizontal and even surface, which is a quick installation and removal to the extent that it can be made in large areas, and which respects safety conditions insofar as as soon as a fire has broken out, it allows the evacuation of smoke and the triggering of the heads of the automatic sprinkler system.

Suivant l'invention, le faux plafond est ainsi réalisé à l'aide de feuilles de matériau léger et souple, soit de matériau textile tissé ou tricoté, soit de matériau non tissé du genre papier, ces feuilles étant divisées en panneaux 2 de dimen­sions et de formes diverses qui sont assemblés les uns aux autres à leur périphérie par un moyen fusible 3.According to the invention, the false ceiling is thus produced using sheets of light and flexible material, either of woven or knitted textile material, or of non-woven material of the paper type, these sheets being divided into panels 2 of dimensions and of various shapes which are assembled to each other at their periphery by a fusible means 3.

Ces panneaux sont, par exemple, de forme carrée (voir figure 1), dont les dimensions sont déterminées par la force du moyen d'assemblage fusible.These panels are, for example, square in shape (see Figure 1), the dimensions of which are determined by the force of the fusible assembly means.

Ce moyen fusible pourra être de nature et de structure très diverses.This fusible means may be of very diverse nature and structure.

Il pourra, par exemple, être réalisé à partir d'un alliage métallique ou de matière plastique du genre résine ou autres.It could, for example, be made from a metal alloy or plastic material of the resin type or the like.

Egalement, la structure de ce moyen fusible pourra être réalisée de façon à assurer, soit un assemblage par points de la périphérie des panneaux, soit un assemblage continu.Also, the structure of this fusible means may be produced so as to ensure either an assembly by points of the periphery of the panels, or a continuous assembly.

Egalement, ce matériau fusible pourra, soit assurer directement l'assemblage des panneaux consti­tuant le faux plafond, soit assurer indirectement cet assemblage en reliant l'un à l'autre des éléments réalisés sous forme de plots, de baguettes ou autres, accrochés à la périphérie des panneaux.Also, this fusible material may either directly ensure the assembly of the panels constituting the false ceiling, or indirectly ensure this assembly by connecting to one another elements produced in the form of studs, rods or the like, attached to the periphery of the panels.

Ce moyen fusible pourra réaliser l'as­semblage des panneaux, soit par collage, soit par accrochage mécanique ou encore faire partie intégrante de la feuille de matériau constituant le faux plafond.This fusible means will be able to assemble the panels, either by gluing, or by mechanical attachment or even being an integral part of the sheet of material constituting the false ceiling.

Dans le cas d'un assemblage par collage, le matériau fusible assurera directement ou indirec­tement, par points ou en continu, la liaison de la périphérie des panneaux, de façon que la fusion de ce matériau se produise dès que la température ambiante atteint sa valeur de fusion prédéterminée, afin que le panneau considéré 2 du faux plafond se détache (voir figure 2) en permettant ainsi, d'une part, l'éva­cuation des fumées et, d'autre part, le déclenchement de la tête d'arrosage automatique 4 du réseau 5 qui est située à la verticale du panneau 2 qui s'est détaché.In the case of assembly by gluing, the fusible material will ensure directly or indirectly, by points or continuously, the connection of the periphery of the panels, so that the fusion of this material occurs as soon as the ambient temperature reaches its value. of predetermined fusion, so that the panel considered 2 of the false ceiling detaches (see Figure 2) thus allowing, on the one hand, the evacuation of smoke and, on the other hand, the triggering of the automatic sprinkler head 4 of the network 5 which is located vertically from the panel 2 which has come off.

Le foyer d'incendie peut ainsi immédiatement être arrosé par les jets d'eau passant au travers de l'ouverture formée dans le faux plafond 1.The fire source can thus be immediately watered by the water jets passing through the opening formed in the false ceiling 1.

Ce moyen fusible agissant par collage pourra être disposé soit sous la forme d'une couche de faible épaisseur, assurant la jonction directe ou indirecte des panneaux, soit sous la forme d'une bande plus ou moins large reliant, à distance l'un de l'autre, les bords des panneaux.This fusible means acting by bonding may be arranged either in the form of a thin layer, ensuring the direct or indirect junction of the panels, or in the form of a more or less wide strip connecting, remotely one of the other, the edges of the panels.

Ce moyen fusible pourra également, suivant sa nature, être réalisé sous la forme d'un moyen d'agrafage mécanique direct ou indirect par points ou en continu de la périphérie des panneaux.This fusible means may also, depending on its nature, be produced in the form of a direct or indirect mechanical stapling means by points or continuously from the periphery of the panels.

Ainsi, par exemple, ce matériau pourra être réalisé sous la forme d'agrafes accrochées à la périphérie des panneaux, soit en les transperçant, soit en les pinçant.Thus, for example, this material could be produced in the form of staples hung on the periphery of the panels, either by piercing them, or by pinching them.

Suivant un autre mode de réalisation de l'invention, il est également prévu de réaliser ce moyen fusible sous la forme d'un fil qui, soit assure la jonction des panneaux par couture, soit fait partie intégrante de la structure du matériau en feuille constituant le faux plafond.According to another embodiment of the invention, it is also intended to produce this fusible means in the form of a wire which either ensures the joining of the panels by sewing, or is an integral part of the structure of the sheet material constituting the false ceiling.

Ainsi, conformément à l'invention, il est prévu de réaliser ce moyen fusible sous la forme d'un fil, alors que la feuille de matériau constituant le faux plafond est réalisée, en totalité ou en partie, sous la forme d'un article à mailles, de façon que au moins certaines des rangées de mailles de cet article, soient réalisées à l'aide de ce fil fusible et délimitent entre elles des panneaux en fil non fusible.Thus, in accordance with the invention, it is planned to produce this fusible means in the form of a wire, while the sheet of material constituting the false ceiling is produced, in whole or in part, in the form of an article. with mesh, so that at least some of the rows of meshes of this article are produced using this fusible wire and delimit between them panels of non-fusible wire.

Les feuilles de matériau souple divisées en panneaux et constituant le faux plafond, pourront être de dimensions très importantes en tenant compte bien entendu de la solidité de l'assemblage des panneaux par le moyen de liaison fusible. Si nécessaire cependant, ce faux plafond pourra être soutenu par un réseau de fils ou de câbles qui, soit supporte le faux plafond, soit est intégré dans la structure de la feuille du matériau souple.The sheets of flexible material divided into panels and constituting the false ceiling, may be of very large dimensions, taking account of course of the solidity of the assembly of the panels by the fusible link means. If necessary, however, this false ceiling can be supported by a network of wires or cables which either supports the false ceiling or is integrated into the structure of the sheet of flexible material.

Egalement, la liaison de la périphérie des panneaux pourra être d'une couleur telle qu'ils se fondent avec la couleur de la feuille de matériau souple constituant le faux plafond, soit au contraire être d'une couleur contrastée afin de réaliser une structure de faux plafond en damiers, telle que représentée sur les figures 1 et 2.Also, the connection of the periphery of the panels could be of a color such that they blend with the color of the sheet of flexible material constituting the false ceiling, or on the contrary be of a contrasting color in order to achieve a structure of false checkered ceiling, as shown in Figures 1 and 2.

Pour répondre à des impératifs techniques ou mécaniques, voire esthétiques, les panneaux 2 pourront être de forme et de disposition très variées. Ainsi, suivant la figure 4, les panneaux 2 de forme générale carrée, sont disposés en quinconces.To meet technical or mechanical or even aesthetic imperatives, the panels 2 can be of very varied shape and layout. Thus, according to Figure 4, the panels 2 of generally square shape, are arranged in staggered rows.

Pour réaliser les faux plafonds conformes à l'invention, on pourra partir du matériau en feuilles se présentant sous la forme de bandes 6 de très grande longueur comme cela est représenté sur la figure 3. Dans ce cas, la bande comporte, à intervalles réguliers, des lignes transversales 7 réalisées à l'aide de ce moyen fusible. Ces bandes peuvent alors être tendues à l'état juxtaposé pour constituer le faux plafond, de façon que la rupture d'une des lignes transversales 7, par suite d'une élévation de température, assure la rupture de la bande considérée de faux plafond. Il est aussi possible d'établir des vélums en joignant ces bandes par un moyen fusible le long de leurs bords longitudinaux.To make the false ceilings according to the invention, it is possible to start from the sheet material in the form of strips 6 of very great length as shown in FIG. 3. In this case, the strip comprises, at regular intervals , transverse lines 7 made at using this medium fuse. These bands can then be stretched in the juxtaposed state to constitute the false ceiling, so that the rupture of one of the transverse lines 7, as a result of a rise in temperature, ensures the rupture of the band considered of false ceiling. It is also possible to establish velums by joining these bands by a fusible means along their longitudinal edges.

Ce mode de fabrication de la feuille sous la forme d'une bande conduira de préférence à la réalisation de cette bande à l'aide d'un tricot et, dans ce cas, la ligne fusible transversale 7 sera réalisée par tricotage d'une ou plusieurs rangées de mailles à l'aide d'un fil fusible.This method of manufacturing the sheet in the form of a strip will preferably lead to the production of this strip using a knitted fabric and, in this case, the transverse fusible line 7 will be produced by knitting one or more several rows of stitches using a fusible wire.

Suivant l'exemple de réalisation des figures 5 et 6, les divers panneaux 1 constituant le faux plafond 2 sont réalisés sous la forme de bandes de grande longueur de matériau souple, qui sont tendues par leurs extrémités 1₁, 1₂ et qui sont juxtaposées horizontalement afin de constituer une surface plane de grandes dimensions pouvant efficacement dissimuler les superstructures d'un bâtiment.According to the embodiment of Figures 5 and 6, the various panels 1 constituting the false ceiling 2 are made in the form of long strips of flexible material, which are stretched by their ends 1₁, 1₂ and which are juxtaposed horizontally so to constitute a large flat surface that can effectively conceal the superstructures of a building.

Ces bandes de matériau souple en feuilles sont réalisées par des nappes de matériau fibreux du genre papier ou sous la forme d'un tissu tissé ou tricoté.These strips of flexible sheet material are produced by sheets of fibrous material of the paper type or in the form of a woven or knitted fabric.

Ces bandes sont reliées les unes aux autres sur leurs bords longitudinaux 3 à l'aide d'un moyen fusible de nature quelconque, fixé par collage, agra­fage ou par tout autre moyen.These strips are connected to each other on their longitudinal edges 3 using a fusible means of any kind, fixed by gluing, stapling or by any other means.

Eventuellement, le faux plafond de grande surface ainsi constitué pourra également être tendu sur ses bords 4 et 5, c'est-à-dire transversalement aux lignes de jonction 3 par les moyens fusibles.Optionally, the false ceiling of large area thus formed may also be stretched on its edges 4 and 5, that is to say transversely to the junction lines 3 by the fusible means.

Il a été découvert que, dans ce cas, lorsqu'un foyer d'incendie 6 se déclare sous un tel faux plafond, la chaleur dégagée produit la fusion locale des lignes de jonction 3, ce qui se traduit, du fait de la tension de montage de chaque bande, par la formation d'ouvertures de grande largeur 7 permettant, d'une part, l'évacuation des fumées vers les parties supérieures du bâtiment, d'autre part le déclenchement des détecteurs de chaleur. Ces détecteurs commandent alors les dispositifs de projection d'eau 7 qui aspergent le foyer par des jets d'eau 8 passant au travers des ouvertures 7 formées dans le faux plafond.It has been discovered that, in this case, when a fire source 6 breaks out under such false ceiling, the heat produced produces the local fusion of the junction lines 3, which results, due to the mounting tension of each strip, by the formation of very wide openings 7 allowing, on the one hand, the 'evacuation of smoke to the upper parts of the building, on the other hand the triggering of heat detectors. These detectors then control the water projection devices 7 which spray the hearth with water jets 8 passing through the openings 7 formed in the false ceiling.

De préférence, le matériau en feuilles constituant les panneaux possédera une élasticité suffisante afin de pouvoir, compte tenu de la tension initiale de montage, dégager des ouvertures de largeur suffisante lors de la rupture, par fusion, des lignes de jonction en matériau à bas point de fusion.Preferably, the sheet material constituting the panels will have sufficient elasticity in order to be able, taking into account the initial mounting tension, to clear openings of sufficient width during the breaking, by fusion, of the junction lines of low point material. of fusion.

Les panneaux constituant les bandes de grande longueur, peuvent eux-mêmes être réalisés de largeur notable, de l'ordre de 2 à 3 mètres par exemple et, dans ce cas, cette bande 9 comporte, comme cela est représenté sur la figure 6, plusieurs lignes 10 à bas point de fusion qui sont orientées longitudinalement en étant régulièrement réparties sur la largeur de cette bande.The panels constituting the strips of great length, can themselves be made of appreciable width, of the order of 2 to 3 meters for example and, in this case, this strip 9 comprises, as shown in FIG. 6, several lines 10 with a low melting point which are oriented longitudinally while being regularly distributed over the width of this strip.

Une telle bande de grande longueur sera de préférence réalisée par tricotage d'un matériau résistant au feu, les lignes fusibles 10 étant obte­nues par une ou plusieurs colonnes de mailles tricotées, lors de la réalisation de la bande, à l'aide d'un fil à bas point de fusion.Such a very long strip will preferably be produced by knitting a fire-resistant material, the fusible lines 10 being obtained by one or more columns of knitted stitches, during the production of the strip, using a low melting point wire.

Cette disposition permettra d'obtenir de manière simple et peu onéreuse, des bandes pourvues d'une élasticité déterminée dans le sens des colonnes de mailles et dans le sens des rangées de mailles. Ces bandes, de grande longueur et de largeur notable, se présentent sous la forme de rouleaux et peuvent, de ce fait, être mises en place rapidement pour constituer un faux plafond.This arrangement will make it possible to obtain in a simple and inexpensive manner, strips provided with a determined elasticity in the direction of the columns of stitches and in the direction of the rows of stitches. These strips, of great length and notable width, are in the form of rolls and can, as a result done, be put in place quickly to constitute a false ceiling.

Egalement, dans ce cas, les bandes 9 de largeur notable constituant les faux plafonds pourront être juxtaposées horizontalement pour constituer un faux plafond, sans que les diverses bandes 9 soient reliées les unes aux autres par une ligne de jonction fusible. En effet, dans ce cas, les bandes de tissu tricoté possèdent en elles-mêmes une élasticité longitudinale et transversale suffisante pour que, lorsque les lignes de jonction 10 sont détruites, ces élasticités longitudinale et transversale produisent le rétrécissement de la largeur des panneaux 11 qui dégagent ainsi des ouvertures de largeur suffisante pour permettre le désenfumage et l'arrosage du foyer d'incendie.Also, in this case, the strips 9 of appreciable width constituting the false ceilings may be juxtaposed horizontally to constitute a false ceiling, without the various strips 9 being connected to each other by a fusible junction line. Indeed, in this case, the strips of knitted fabric have in themselves sufficient longitudinal and transverse elasticity so that, when the joining lines 10 are destroyed, these longitudinal and transverse elasticities produce the narrowing of the width of the panels 11 which thus open openings of sufficient width to allow smoke extraction and watering of the fire.
