La présente invention se rapporte à un élément de boîtier de protection incendie pour des éléments encastrés dans les cloisons et contre-cloisons, en particulier pour les appareillages électriques.  The present invention relates to a fire protection housing element for recessed elements in partitions and bulkheads, in particular for electrical equipment.
Les cloisons, et en particulier les cloisons coupe-feu, ont des espaces vides à l'intérieur entre les plaques de parement. Dans ces espaces vides peuvent être insérés des appareils par exemple des appareils électriques, des prises électriques et plus généralement tous types d'appareillages électriques. Or, il est nécessaire d'isoler ces appareillages électriques pour éviter les risques de propagation du feu au travers de la cloison, et maintenir la performance acoustique de la cloison.  Partitions, and in particular fire partitions, have empty spaces in between the facing plates. In these empty spaces can be inserted devices such as electrical appliances, electrical outlets and more generally all types of electrical equipment. However, it is necessary to isolate these electrical devices to avoid the risk of fire spread through the partition, and maintain the acoustic performance of the partition.
Actuellement, la protection des appareillages électriques peut être réalisée par un électricien ou un plaquiste par colmatage d'une quantité de colle ou de plâtre dans l'espace vide de la cloison, ou par incorporation d'une protection isolante intumescente.  Currently, the protection of electrical equipment can be performed by an electrician or a plaquiste by sealing a quantity of glue or plaster in the empty space of the partition, or by incorporating an intumescent insulating protection.
Or, lorsque l'électricien ou le plaquiste souhaite mettre en place des boîtiers de prises électriques multiples, ou mettre en place des boîtiers l'un en face de l'autre (sans décalage d'un parement à l'autre de la cloison), les solutions existantes ne permettent pas de résoudre ces besoins.  However, when the electrician or the plaquist wants to set up multiple electrical outlets, or set up boxes facing each other (without shifting from one facing to the other of the partition) existing solutions do not solve these needs.
Afin de répondre aux exigences des industriels, il est devenu nécessaire de trouver un autre moyen pour isoler ces appareillages électriques et éviter les risques de propagation du feu.  In order to meet the requirements of industry, it became necessary to find another way to isolate these electrical equipment and avoid the risk of fire spread.
Aussi le problème que se propose de résoudre l'invention est de fournir un nouveau moyen adapté pour protéger ces appareillages électriques tout en permettant de positionner des appareils multiprises et/ou en vis-à-vis sur chaque coté de la cloison.  Also the problem to be solved by the invention is to provide a new means adapted to protect these electrical devices while allowing to position multiple devices and / or vis-à-vis on each side of the partition.
Dans ce but la présente invention se rapporte à un élément de boîtier de protection contre le feu réalisé en plaques de plâtre, ainsi qu'à une cloison comprenant cet élément de boîtier.  For this purpose the present invention relates to a fire protection housing element made of gypsum board, as well as to a partition comprising this housing element.
