Title
(EN) INTUMESCENT GRILLE UNIT
(FR) UNITÉ DE GRILLE INTUMESCENTE
Abstract
(EN)
Herein is provided an intumescent grille unit comprising: a plurality of slats, the slats being spaced apart to allow airflow between them, wherein each of the slats has opposing faces, and edges linking the opposing faces, the slats comprising: a core comprising an intumescent material; a non-intumescent outer shell, the shell having a static first portion, and a movable second portion connected to the first portion by a hinged or weakened section that extends along a direction substantially parallel to the edge of the slat, the second portion forming at least a portion of a face of the slat, wherein, on expansion of the intumescent material on exposure to heat, the second portion moves rotatably about the hinged or weakened section, to form a wall that extends toward an adjacent slat, reducing or preventing airflow between adjacent slats.
(FR)
La présente invention concerne une unité de grille intumescente comprenant : une pluralité de lattes, les lattes étant espacées pour permettre un écoulement d'air entre celles-ci, chacune des lattes ayant des faces opposées, et des bords reliant les faces opposées, les lattes comprenant : un noyau comprenant un matériau intumescent ; une enveloppe externe non intumescente, l'enveloppe ayant une première partie statique, et une deuxième partie mobile raccordée à la première partie par une section articulée ou affaiblie qui s'étend le long d'une direction sensiblement parallèle au bord de la latte, la deuxième partie formant au moins une partie d'une face de la latte, dans lequel, lors de l'expansion du matériau intumescent par exposition à la chaleur, la deuxième partie se déplace de façon rotative autour de la section articulée ou affaiblie, pour former une paroi qui s'étend vers une latte adjacente, de façon à réduire ou empêcher un écoulement d'air entre des lattes adjacentes.
