Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne un procédé d'installation d'un détecteur de fumée ou d'autres éléments techniques sur un plafond tendu déjà posé.The invention relates to a method of installing a smoke detector or other technical elements on a stretched ceiling already laid.

Le procédé est destiné notamment, mais non exclusivement, à l'installation de détecteurs photo-électriques ou optiques.The method is intended in particular, but not exclusively, for the installation of photoelectric or optical detectors.

ETAT DE LA TECHNIQUESTATE OF THE ART

Il est répandu d'utiliser des plafonds tendus lors de la construction ou la rénovation de bâtiments. Constitués en général d'une toile souple en matière synthétique, les plafonds tendus permettent d'une part d'abaisser la hauteur du plafond, mais également de cacher des installations inesthétiques telles que des installations électriques, des conduits, etc.It is common to use stretch ceilings when building or renovating buildings. Generally made of a flexible canvas made of synthetic material, stretch ceilings allow on the one hand to lower the height of the ceiling, but also to hide unsightly installations such as electrical installations, ducts, etc.

Lorsqu'il est envisagé d'installer un plafond tendu, il est nécessaire de prévoir, préalablement à la pose de la toile, les structures additionnelles pour l'encastrement dans le plafond tendu d'appareils techniques tels que des détecteurs de fumées. Ainsi, on procède à la fixation des structures additionnelles sur le plafond existant, puis à l'installation de la toile tendue et enfin à la fixation des appareils techniques en question.When it is considered to install a stretch ceiling, it is necessary to provide, prior to the installation of the fabric, the additional structures for the installation in the stretched ceiling of technical devices such as smoke detectors. Thus, one proceeds to the fixing of the additional structures on the existing ceiling, then to the installation of the stretched canvas and finally to the fixing of the technical devices in question.

Dans le cadre d'une nouvelle réglementation française visant à rendre l'installation de détecteurs de fumée obligatoire dans les logements, il est recommandé d'installer les détecteurs de fumées au plafond, à distance des parois murales.As part of a new French regulation to make the installation of smoke detectors mandatory in housing, it is recommended to install the smoke detectors on the ceiling, away from the walls.

Le problématique qui se pose est donc celle des plafonds tendus déjà installés et pour lesquels il n'a pas été prévu de détecteur de fumée ou du moins des structures permettant la fixation des détecteurs au plafond. Il s'avère donc nécessaire de démonter la toile tendue au niveau d'au moins deux des parois murales afin de pouvoir accéder au plafond existant et fixer les structures de fixation des détecteurs de fumées. Cette technique présente cependant l'inconvénient d'être longue et fastidieuse. Il faut en effet décrocher la toile sur deux des parois au moins en prenant soin de ne pas abîmer la toile, fixer la structure de fixation du détecteur de fumée à installer, réenclencher la toile sur les parois concernées, retrouver par tâtonnement de la toile l'emplacement de la structure de fixation du détecteur de fumée, découper la toile pour accéder à la structure de fixation et fixer le détecteur de fumée.The problem that arises is that of stretch ceilings already installed and for which it has not been planned smoke detector or at least structures for fixing detectors on the ceiling. It is therefore necessary to dismantle the stretched fabric at at least two of the wall walls in order to access the existing ceiling and fix the mounting structures of the smoke detectors. This technique, however, has the disadvantage of being long and tedious. We must indeed unhook the canvas on two of the walls at least taking care not to damage the canvas, fix the mounting structure of the smoke detector to install, reset the canvas on the walls concerned, find by trial of the canvas l location of the mounting structure of the smoke detector, cut the fabric to access the fastening structure and fix the smoke detector.

L'invention vise à remédier à ces problèmes en proposant un procédé d'installation permettant d'installer un appareil technique tel qu'un détecteur de fumée sur un faux plafond formé d'une toile souple tendue de manière simple, rapide et sécurisée, et ne nécessitant pas un démontage de la toile pour accéder au plafond.The invention aims to remedy these problems by proposing an installation method for installing a technical device such as a smoke detector on a false ceiling formed of a flexible fabric stretched in a simple, fast and secure manner, and not requiring disassembly of the canvas to access the ceiling.

Le document FR 2 647 139 A1 divulgue un procédé selon le préambule de la revendication 1. Dans ce procédé l'appareil technique est maintenu écarté de la rondelle de renfort.The document FR 2 647 139 A1 discloses a method according to the preamble of claim 1. In this method the technical apparatus is kept away from the reinforcing washer.

Avantageusement, l'ouverture de passage est réalisée par découpage de la toile le long de la bordure intérieure de la rondelle de renfort.Advantageously, the passage opening is made by cutting the fabric along the inner edge of the reinforcing washer.

Avantageusement, l'ouverture de passage présente une section de passage inférieure au diamètre nominal de l'appareil technique.Advantageously, the passage opening has a passage section smaller than the nominal diameter of the technical apparatus.

Avantageusement, le procédé comporte une étape de réglage en hauteur de la structure de fixation intermédiaire, mise en place dans l'espace résiduel, pour placer la plaque de base de la structure de fixation intermédiaire au niveau de l'ouverture de passage.Advantageously, the method comprises a step of adjusting the height of the intermediate fixing structure, placed in the residual space, to place the base plate of the intermediate fixing structure at the passage opening.

Avantageusement, la plaque de base est disposée de manière à affleurer la face de la toile souple tendue située du côté de l'espace résiduel.Advantageously, the base plate is arranged to be flush with the face of the stretched flexible fabric located on the side of the residual space.

Other objects and advantages of the invention will become apparent from the following description, made with reference to the appended drawings, in which:
  • the figure 1 is a mounting bracket and smoke detector assembly for attachment to an existing stretch ceiling,
  • the Figures 2 to 5 represent the steps of installing a smoke detector on an existing false ceiling.

DESCRIPTION DETAILLEE DES FIGURESDETAILED DESCRIPTION OF THE FIGURES

En relation avec les figures, il est décrit un procédé d'installation d'un détecteur de fumée 1 sur un faux-plafond existant du type plafond tendu 2 d'un local.In connection with the figures, there is described a method of installing a smoke detector 1 on an existing false ceilings type stretch ceiling 2 of a room.

De manière connue, les détecteurs de fumée comprennent une plaque de montage destiné à être fixée sur le plafond et un corps principal comportant les éléments techniques nécessaires à la détection de fumée et au déclenchement d'une alarme. A titre d'exemple, le corps principal des détecteurs de fumée photo-électriques comprend une chambre optique dans laquelle sont installés une diode destinée à émettre de façon périodique des rayons de lumière et une lentille photo-électrique, ainsi que des moyens d'alarme aptes à se déclencher lorsque les rayons émis par la diode sont dispersés et renvoyés vers la lentille photo-électrique.In a known manner, the smoke detectors comprise a mounting plate intended to be fixed on the ceiling and a main body comprising the technical elements necessary for the detection of smoke and the triggering of an alarm. For example, the main body of the photoelectric smoke detectors comprises an optical chamber in which are installed a diode for periodically emitting rays of light and a photoelectric lens, as well as alarm means. able to trigger when the rays emitted by the diode are scattered and returned to the photoelectric lens.

Le plafond tendu 2 comporte une toile souple 3 tendue horizontalement en dessous du plafond (non représenté) du local. Cette toile souple 3 est fixée aux parois murales du local via une lisse 4 formée de profils aboutés. La lisse 4 est fixée aux parois murales par des moyens de fixation appropriés tels que des vis à la hauteur de plafond souhaitée. Une fois la toile souple 3 posée, il existe donc un espace résiduel 13, nommé également vélum 13, situé entre le plafond 12 du local et la toile souple 3.The stretched ceiling 2 comprises a flexible fabric 3 stretched horizontally below the ceiling (not shown) of the room. This flexible fabric 3 is attached to the walls of the room via a smooth 4 formed of abutting profiles. The arm 4 is fixed to the wall walls by appropriate fastening means such as screws to the desired ceiling height. Once the flexible fabric 3 is placed, there is therefore a residual space 13, also called velum 13, located between the ceiling 12 of the room and the flexible fabric 3.

On désignera par la référence 3 indifféremment les termes de « toile », « toile tendue », « toile souple ».The term "canvas", "stretched canvas", "flexible cloth" will be referred to by the reference 3 indifferently.

La première étape pour installer un détecteur de fumée lorsque le plafond tendu 2 est déjà en place consiste à déterminer l'emplacement approprié du détecteur de fumée 1 à installer sur la toile souple 3 tendue. L'installation de ce dernier est en effet conditionnée par les éléments existant dans le vélum 13 tels que les tuyaux, les installations électriques, etc.. Dans la mesure du possible, le détecteur de fumée 1 sera positionné en partie centrale du plafond tendu 2 comme le recommandent les organismes de prévention d'incendies.The first step in installing a smoke detector when the stretch ceiling 2 is already in place is to determine the appropriate location of the smoke detector 1 to be installed on the flexible fabric 3 stretched. The installation of the latter is in fact conditioned by the existing elements in the velum 13 such as pipes, electrical installations, etc. As far as possible, the smoke detector 1 will be positioned in the central part of the stretched ceiling 2 as recommended by fire prevention organizations.

Dans le cas particulier où l'emplacement des éléments intégrés dans le plénum n'est pas connu, il convient, préalablement à la détermination de l'emplacement du détecteur de fumée, de procéder à un repérage de ces éléments intégrés dans le vélum 13. Pour ce faire, la toile est décrochée partiellement au niveau de l'un de ses bords afin de pouvoir accéder visuellement au vélum 13 et ainsi déterminer les zones libres, ie les zones dépourvues d'installation ou similaire. Le décrochage de la toile souple 3 est réalisé sur une distance de deux mètres environ. La distance décrochée variera en fonction de l'étendue du vélum 13 et de la visibilité de celui-ci.In the particular case where the location of the elements integrated in the plenum is not known, it is appropriate, prior to the determination of the location of the smoke detector, to identify these integrated elements in the velum 13. To do this, the canvas is unhooked partially at one of its edges in order to to be able to visually access the velum 13 and thus to determine the free zones, ie the zones devoid of installation or the like. The stall of the flexible fabric 3 is made over a distance of about two meters. The unhooked distance will vary according to the extent of the awning 13 and the visibility of it.

Une fois l'emplacement ou les emplacements libre(s) déterminé(s), il est procédé au marquage de la toile. Le marquage 5 est réalisé sur la face extérieure de la toile 3. On désigne par « face extérieure » la face de la toile souple 3 située du côté du local, et par « face intérieure », la face de la toile souple 3 située du côté de l'espace résiduel.Once the location or free locations are determined, the canvas is marked. The marking 5 is made on the outer face of the fabric 3. The term "outer face" refers to the face of the flexible fabric 3 located on the side of the local, and "inner face", the face of the flexible fabric 3 located on the side of the residual space.

Avantageusement, le marquage 5 est effaçable. Cela permet ainsi de ne pas endommager la toile en cas d'erreur dans la détermination de l'emplacement.Advantageously, the marking 5 is erasable. This makes it possible not to damage the canvas in case of error in the determination of the location.

Il est ensuite procédé à l'installation d'une rondelle de renfort 6 au niveau du marquage 5 de l'emplacement (figure 2). Pour ce faire, la rondelle de renfort 6, de forme annulaire, est collée de manière coaxiale au marquage 5. La partie 30 de la toile s'étendant au niveau de l'évidemment central de la rondelle de renfort 6 est alors découpée, réalisant ainsi une ouverture de passage 7 vers le vélum 13 (figure 3). Plus particulièrement, la découpe est réalisée en longeant la bordure intérieure 61 de la rondelle de renfort 6. Le découpage de la partie 30 de la toile est réalisée à l'aide de tout moyen de découpe approprié. Il est bien entendu évident que la rondelle de renfort 6 peut prendre d'autres formes. Elle devra cependant présenter un évidemment, central ou non, de manière à permettre la découpe de la toile.It is then proceeded to the installation of a reinforcing washer 6 at the marking 5 of the location ( figure 2 ). To do this, the annular reinforcing washer 6 is glued coaxially to the marking 5. The portion 30 of the fabric extending at the central recess of the reinforcing washer 6 is then cut, realizing thus an opening of passage 7 towards the velum 13 ( figure 3 ). More particularly, the cut is made along the inner edge 61 of the reinforcing washer 6. The cutting of the portion 30 of the fabric is performed using any suitable cutting means. It is of course obvious that the reinforcing washer 6 can take other forms. However, it must present an obvious, central or not, so as to allow the cutting of the canvas.

Outre la fonction de renfort de la toile au niveau de l'évidement, la rondelle de renfort 6 a également pour fonction de guide pour la découpe de la toile 3 ainsi que, comme on le verra plus loin, de surface d'appui pour le détecteur de fumée 1. Elle permet en outre d'améliorer l'étanchéité de la toile 3 une fois le détecteur de fumée 1 installé.In addition to the reinforcing function of the fabric at the level of the recess, the reinforcing washer 6 also serves as a guide for cutting the fabric 3 and, as will be seen below, as a support surface for the fabric. smoke detector 1. It also makes it possible to improve the tightness of the fabric 3 once the smoke detector 1 has been installed.

L'ouverture de passage 7 vers le vélum 13 étant réalisée, il est procédé à la mise à place de la structure de fixation intermédiaire 9 sur laquelle le détecteur de fumée 1 va être fixé (figure 4). La structure de fixation intermédiaire 9 comporte une partie supérieure 10 en forme d'étrier ouvert vers le bas raccordée, en partie inférieure, à une plaque de base 8 horizontale traversée en son centre par un orifice 80 de diamètre adapté à l'appareil à intégrer. L'orifice 80 permet le passage de l'outil 9 permettant la fixation de la partie supérieure de la structure de fixation intermédiaire 9 au plafond 12 comme illustré sur la figure 3.The passage opening 7 towards the awning 13 being realized, the intermediate fixing structure 9 on which the smoke detector 1 is going to be fixed is placed in place ( figure 4 ). The intermediate fixing structure 9 comprises an upper part 10 in the form of a stirrup open downwards connected, in the lower part, to a horizontal base plate 8 traversed at its center by an orifice 80 of diameter adapted to the device to integrate. The orifice 80 allows the passage of the tool 9 allowing the attachment of the upper part of the intermediate fixing structure 9 to the ceiling 12 as shown in FIG. figure 3 .

Selon une configuration préférée, la plaque de base 8 est reliée à la partie supérieure de la structure de fixation intermédiaire 9 de manière réglable en hauteur. Le réglage en hauteur permet ainsi d'ajuster la position de la plaque de base 8 par rapport à l'ouverture de passage 7. Dans le mode de réalisation illustré (figure 4), la structure de fixation intermédiaire 9 est réglée de manière à positionner la plaque de base 8 au niveau de l'ouverture de passage 7. En particulier, il sera choisi de placer la plaque de base 8 directement dans l'ouverture de passage 7 ou juste au-dessus, dans le vélum 13.According to a preferred configuration, the base plate 8 is connected to the upper part of the intermediate fixing structure 9 in a height-adjustable manner. The height adjustment thus makes it possible to adjust the position of the base plate 8 with respect to the passage opening 7. In the illustrated embodiment (FIG. figure 4 ), the intermediate fixing structure 9 is adjusted so as to position the base plate 8 at the passage opening 7. In particular, it will be chosen to place the base plate 8 directly in the passage opening 7 or just above, in the velum 13.

Il est bien entendu évident que l'invention ne se limite pas à ce type de structure de fixation intermédiaire 9, et qu'il peut être prévu d'autres types de configuration sans pour autant sortir du cadre de l'inventionIt is of course obvious that the invention is not limited to this type of intermediate fastening structure 9, and that other types of configuration can be provided without departing from the scope of the invention.

La structure de fixation intermédiaire 9 est passée au travers de l'ouverture de passage 7 puis fixée sur le plafond 12 par vissage à l'aide de l'outil (ici un tournevis) d'un tournevis passé au travers de l'orifice 80 de diamètre adapté à l'appareil. La structure de fixation intermédiaire est ensuite réglée de manière à positionner la plaque de base au niveau de l'ouverture.The intermediate fixing structure 9 is passed through the passage opening 7 and then fixed to the ceiling 12 by screwing with the aid of the tool (here a screwdriver) a screwdriver passed through the orifice 80 of diameter adapted to the apparatus. The intermediate fastening structure is then adjusted to position the base plate at the opening.

Une fois la structure de fixation intermédiaire 9 fixée sur le plafond 12 existant et réglée à la hauteur adéquate, le détecteur de fumée 1 est fixé sur la plaque de base 8 (figure 5). L'étape de fixation du détecteur consiste à fixer le support du détecteur de fumée 1 sur la plaque de base 8. Dans le mode de réalisation décrit, le support de détecteur est fixé par vissage. Les dimensions du support de détecteur sont telles qu'il est plaqué contre la rondelle de renfort 6. Le corps principal 11 du détecteur de fumée 1 est ensuite fixé sur le support de détecteur. La fixation pourra être réalisée par clipsage, vissage ou similaire selon le modèle de détecteur de fumée.Once the intermediate fixation structure 9 is fixed on the existing ceiling 12 and set to the appropriate height, the smoke detector 1 is fixed on the base plate 8 ( figure 5 ). The step of fixing the detector consists of fixing the support of the smoke detector 1 on the base plate 8. In the embodiment described, the detector support is fixed by screwing. The dimensions of the detector support are such that it is pressed against the reinforcing washer 6. The main body 11 of the smoke detector 1 is then fixed on the detector support. The attachment may be made by clipping, screwing or the like according to the model of smoke detector.

Dans le mode de réalisation précédemment décrit, le détecteur de fumée est installé sur une fausse-paroi de type faux-plafond. La méthode décrite peut toutefois être mise en oeuvre pour une fausse-paroi de type faux-mur. Bien que l'exemple décrit précédemment se rapporte à l'installation d'un détecteur de fumée, il est bien entendu évident que l'invention ne se limite pas à ce type d'appareil et que le procédé décrit peut être mis en oeuvre pour d'autres types d'appareils destinés à être appliqués sur un plafond tendu préalablement posé.In the embodiment previously described, the smoke detector is installed on a false-wall type false ceiling. The method described can, however, be implemented for a fake wall-type false-wall. Although the example described above relates to the installation of a smoke detector, it is of course obvious that the invention is not limited to this type of apparatus and that the method described can be implemented for other types of apparatus intended to be applied to a stretched ceiling previously laid.

L'invention est décrite dans ce qui précède à titre d'exemple.The invention is described in the foregoing by way of example.
