Abstract
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.
