Description

Dalle de plafond  Ceiling slab
La présente invention porte sur des éléments d'habillage de plafond sous forme de dalles.  The present invention relates to elements of ceiling cladding in the form of slabs.
Les dalles de plafond sont généralement utilisées pour recouvrir un plafond présentant des irrégularités ou bien pour donner une nouvelle esthétique à un plafond sobre. Les dalles de plafonds présentent l'avantage d'être isolantes thermiquement et phoniquement et de préserver le plafond de la poussière, tout en conservant une légèreté aidant à la pose de ces dernières.  Ceiling tiles are generally used to cover a ceiling with irregularities or to give a new aesthetic to a sober ceiling. The ceiling tiles have the advantage of being thermally and acoustically insulating and to preserve the ceiling of the dust, while maintaining a lightness that helps to install the latter.
il existe plusieurs types de dalles de plafond : les dalles à fibres comprimées, les dalles métalliques, les dalles en bois. Cependant, toutes ces dalles présentent des inconvénients. En effet, les dalles à fibres comprimées gondolent avec l'humidité, et sont poussiéreuses et peu esthétiques ; les dalles métalliques sont des dalles lourdes qui sont susceptibles de rouiller avec l'humidité ; les dalles en bois sont très chères et lourdes, ce qui ne facilite pas la pose sur le plafond.  There are several types of ceiling tiles: compressed fiber slabs, metal slabs, wooden slabs. However, all these slabs have disadvantages. Indeed, compressed fiber slabs curl with moisture, and are dusty and unsightly; metal slabs are heavy slabs that may rust with moisture; the wooden slabs are very expensive and heavy, which does not facilitate the installation on the ceiling.
Pour pallier ces inconvénients, il a été proposé des dalles en matériau plastique (Polychlorure de vinyle) ou composite notamment pour la pose dans les laboratoires, mais ces dernières sont très peu esthétiques.  To overcome these disadvantages, it has been proposed slabs of plastic material (polyvinyl chloride) or composite including for laying in laboratories, but these are very unattractive.
L'invention a pour but de remédier à tout ou partie des inconvénients précités.  The object of the invention is to remedy all or some of the aforementioned drawbacks.
L'invention a pour objet une dalle de plafond en matériau plastique ou composite comprenant une première face destinée à être fixée au plafond, une deuxième face opposée à la première face, la deuxième face présentant un décor, caractérisée en ce que la daile comprend au moins un ajour ménagé sur la deuxième face et formant une ouverture traversant la dalle de part en part, et en ce que la daile comprend une couche de revêtement appliquée sur la première face, la couche de revêtement étant configurée pour obturer au moins partiellement ledit au moins un ajour.  The invention relates to a ceiling tile made of plastic or composite material comprising a first face intended to be fixed to the ceiling, a second face opposite to the first face, the second face having a decoration, characterized in that the daile comprises at least one aperture formed on the second face and forming an opening through the slab from one side to the other, and in that the daile comprises a coating layer applied to the first face, the coating layer being configured to close at least partially said less an ajour.
La dalle selon l'invention présente une fonction décorative sur la deuxième face par l'utilisation d'au moins un ajour allégeant la forme de la dalle et une fonction technique par l'utilisation d'une couche de revêtement qui vient obturer au moins partiellement cet ajour sur la première face de la dalle de manière à conserver les propriétés d'isolation thermique et phonique de ladite dalle. L'application d'une couche de revêtement sur la première face a également une fonction esthétique révélant la profondeur de la dalle par un jeu de transparence, ce qui se démarque considérablement de l'art antérieur.  The slab according to the invention has a decorative function on the second face by the use of at least one openwork lightening the shape of the slab and a technical function by the use of a coating layer which closes at least partially this ajour on the first face of the slab so as to retain the thermal and sound insulation properties of said slab. The application of a coating layer on the first face also has an aesthetic function revealing the depth of the slab by a set of transparency, which differs considerably from the prior art.
Selon une caractéristique de l'invention, la dalle comprend une pluralité d'ajours répartis sur la deuxième face de ladite dalle. Selon une caractéristique de l'invention, le décor de la dalle de plafond est formé par le au moins un ajour ou une pluralité d'ajours. According to one characteristic of the invention, the slab comprises a plurality of openings distributed on the second face of said slab. According to one characteristic of the invention, the decoration of the ceiling tile is formed by the at least one aperture or a plurality of openings.
Selon une caractéristique de l'invention, les ajours sont répartis de manière régulière ou aléatoire sur la deuxième face de la dalle. La répartition des ajours est réalisée en fonction du motif choisi par l'utilisateur.  According to one characteristic of the invention, the openings are distributed regularly or randomly on the second face of the slab. The distribution of the openings is made according to the pattern chosen by the user.
Selon une caractéristique de l'invention, les ajours sont de forme circulaire ou carrée ou polygonale.  According to a feature of the invention, the openings are circular or square or polygonal.
Selon une caractéristique de l'invention, la couche de revêtement recouvre entièrement la première face de la dalle, ce qui facilite la pose de ladite couche de revêtement.  According to one characteristic of the invention, the coating layer completely covers the first face of the slab, which facilitates the laying of said coating layer.
Alternativement, la couche de revêtement ne couvre que les ajours de manière entière ou partielle, ce qui présente l'avantage de baisser les coûts de la dalle et de ne pas alourdir la daiie.  Alternatively, the coating layer covers only the openings completely or partially, which has the advantage of lowering the costs of the slab and not to increase the daiie.
Selon une caractéristique de l'invention, la couche de revêtement obture tous les ajours, pour l'obtention d'une isolation thermique et phonique optimale.  According to one characteristic of the invention, the coating layer closes all the openings, in order to obtain optimum thermal and sound insulation.
