L'invention concerne un collier coupe-feu de drain de vidange de plancher, destiné à empêcher la sortie de fumée et de feu entre des étages dans un immeuble à plusieurs étages. Le collier coupe-feu (58) a un boîtier externe (70) avec une bride murale supérieure (76) et un capuchon d'étanchéité amovible (78) dans la bride supérieure, un corps tubulaire (80) est reçu dans le boîtier externe et est mobile longitudinalement à l'intérieur du boîtier externe d'une position dans laquelle il est reçu à l'intérieur du boîtier externe à une position dans laquelle une extrémité supérieure du corps tubulaire s'étend au-delà du boîtier externe. Le corps tubulaire a un siège de soupape (86) et un ensemble de soupape (88). L'ensemble de soupape a un élément de soupape qui, dans une première position, permet un écoulement à travers le trajet d'écoulement et, dans une seconde position, est engagé contre le siège de soupape pour empêcher un écoulement à travers le corps tubulaire. L'ensemble de soupape comprend un matériau intumescent (90). Un thermofusible (100) maintient l'élément de soupape dans la première position à l'encontre d'une force de ressort (102), ce par quoi, lorsque le thermofusible a été chauffé par un feu au-dessus d'une température sélectionnée, l'élément de soupape se déplace à la seconde position pour empêcher la fumée et le feu de passer à travers le collier coupe-feu de drain de vidange de plancher.
