Abstract

Un collarín contra el fuego (10) es soportado alrededor de un tubo(30) de material de plástico que se extiende a través de un orificio (32) en una pared (44). El collarín contra fuego (10) comprende un collarín de metal cilíndrico (12) que lleva una capa de material intumescente (36) sobre su superficie circunferencial interior. Un manguito (22) de material resistente al fuego está unido al collarín de metal (10) y se extiende dentro del collarín y alrededor del tubo (30). En el caso de un incendio el tubo (30) se funde. El material intumescente (36) es restringido para expandirse radialmente hacia adentro y a medida que lo hace empuja al manguito de tela (22) radialmente hacia adentro. El manguito (22) y el material intumescente expandido (36) juntos forman una barrera física a través del collarín contra el fuego (10) el cual bloquea al orificio (32).
