One aspect of the present invention provides a poke-through assembly for installation in a hole in a floor structure. The floor structure defines a floor in a first working environment and a ceiling in a second working environment. The poke-through assembly includes at least one intumescent member, a base plate and an intumescent enclosure. The intumescent member is disposed at least partially between the floor of the first working environment and the ceiling of the second working environment. The base plate supports and is disposed below the intumescent member for limiting the expansion of the intumescent member toward or into the second working environment. Another aspect of the present invention provides a poke-through assembly including an upper frame, at least one intumescent member and an intumescent cover. The intumescent member is disposed below the upper frame. The intumescent cover supports the intumescent member and circumferentially surrounds at least a portion of the intumescent member, wherein expansion of the intumescent member is impeded by the cover.
Un aspect de la présente invention procure notamment un ensemble de sol pour l'installation d'un trou dans une structure de plancher. La structure de plancher définit un plancher dans un premier environnement de travail et un plafond dans un second environnement de travail. L'ensemble de sol comprend au moins un élément intumescent, une plaque de base et une enceinte intumescente. L'élément intumescent est disposé au moins partiellement entre le plancher du premier environnement de travail et le plafond du second environnement de travail. La plaque de base soutient l'élément intumescent et elle est disposée sous ce dernier afin de limiter l'expansion de l'élément intumescent vers ou dans le second environnement de travail. La présente invention procure également un ensemble de sol comprenant un cadre supérieur, au moins un élément intumescent et un revêtement intumescent. L'élément intumescent est disposé sous le cadre supérieur. Le revêtement intumescent soutient l'élément intumescent et entoure de manière circonférentielle au moins une partie de l'élément intumescent, l'expansion de l'élément intumescent étant entravée par le revêtement.
