Abstract

L'invention porte sur une structure de tuyau ignifuge et absorbant le bruit placée à l'intérieur d'une maison. Une partie trou débouchant d'un carrelage constituant un plancher ou un plafond ou un mur de l'intérieur de la maison comporte une structure de tuyau pourvue uniquement d'une couche ignifuge sur la périphérie externe d'un tuyau rigide en résine, et une partie autre que le trou débouchant possède une structure de tuyau pourvue d'une couche absorbant le bruit sur la surface périphérique externe de la couche ignifuge. Du fait que la partie trou débouchant du carrelage possède une structure de tuyau pourvue uniquement de la couche ignifuge sur la périphérie externe du tuyau rigide en résine, cette structure de tuyau peut être agencée dans le même espace que les tuyaux double couche ignifuges traditionnels. Les parties de cette structure de tuyau ignifuge et absorbant le bruit différentes de la partie trou traversant ont une structure de tuyau pourvue d'une couche absorbant le bruit sur la surface périphérique externe de la couche ignifuge, ce système empêchant ainsi efficacement le bruit, généré par un fluide s'écoulant dans le tuyau, de se répandre dans les pièces de la maison.
