Head-of-wall firestopping insulation construction for fluted deck

摘要

A firestopping insulation construction adapted to be positioned adjacent to a head-of-wall area beneath a ceiling construction having fluted ceiling runner channels which have a trapezoidal cross-sectional profile facing downwardly. The insulation assembly includes an upper plug mated the shape of the fluted channel which is at least partially surrounded by an outer cover and further includes a lower insulation section extending over the side walls of the head-of-wall area. The upper insulation plug and the lower insulation sections are preferably made of molded high temperature insulation. The insulation assembly is engaged only frictionally to the fluted ceiling channels.

1. A head-of-wall firestopping construction positionable in a head-of-wall area defined between a ceiling thereabove and a wall construction therebelow wherein the ceiling includes a fluted ceiling deck which defines at least one ceiling runner channel therein with recessed areas defined therein facing downwardly toward the head-of-wall area therebelow with the at least one ceiling runner channel including an upper recess panel extending generally horizontally and including a first recess side panel engaging the upper recess panel and extending downwardly and outwardly therefrom and including a second recess side panel engaging the upper recess panel at a position spatially disposed from the first recess side panel and extending downwardly and outwardly from the upper recess panel in a direction extending away from the first recess side panel, the head-of-wall firestopping construction also being for use with a wall construction extending generally vertically and positioned below the head-of-wall area which includes a plurality of wall studs with a first gypsum board construction attached thereto and a second gypsum board construction attached thereto at a position spatially disposed from the first gypsum board construction, said head-of-wall firestopping construction including:
A. a first insulation member of fire insulating material positioned extending into one of said recessed areas defined in the ceiling and being in frictional engagement with respect to the fluted ceiling deck and extending downwardly therefrom into the head-of-wall area, said first insulation member comprising:
(1) a first upper insulation section of fire insulating material extending into one of said recessed areas defined thereabove in at least one ceiling runner channel in the ceiling into abutment with respect to the fluted ceiling deck in one of said recessed areas thereof, said first upper insulation section including:
(a) a first upper insulation horizontal surface defined extending horizontally thereon;(b) a first upper insulation primary inclined surface attached to said first upper insulation horizontal surface and extending downwardly and outwardly therefrom, said first upper insulation primary inclined surface being positioned in abutment with the first recess side panel for facilitating frictionally movable attachment with respect thereto;(c) a first upper insulation secondary inclined surface attached to said first upper insulation horizontal surface at a position spatially disposed from said first upper insulation primary inclined surface and extending downwardly and outwardly therefrom, said first upper insulation secondary inclined surface being positioned in abutment with the second recess side panel for facilitating frictionally movable attachment with respect thereto;(d) a first upper insulation exterior surface extending generally vertically and facing outwardly with respect to the head-of-wall area above the first gypsum board construction;(2) a first lower insulation section of fire insulating material attached to said first upper insulation section and extending downwardly therefrom to a position in abutment with and extending over the first gypsum board construction for firestopping thereadjacent, said first lower insulation section defining a first lower insulation exterior surface extending generally vertically and facing outwardly from the head-of-wall area; B. a second insulation member of fire insulating material positioned extending into one of said recessed areas defined in the ceiling and being in frictional engagement with respect to the fluted ceiling deck and extending downwardly therefrom into the head-of-wall area, said second insulation member comprising:
(1) a second upper insulation section of fire insulating material extending into one of said recessed areas defined thereabove in a ceiling runner channel in the ceiling into abutment with respect to the fluted ceiling deck in one of said recessed areas thereof, said second upper insulation section including:
(a) a second upper insulation horizontal surface defined extending horizontally thereon;(b) a second upper insulation primary inclined surface attached to said second upper insulation surface horizontal surface and extending downwardly and outwardly therefrom, said second upper insulation primary inclined surface being positioned in abutment with the first recess side panel for facilitating frictionally movable attachment with respect thereto;(c) a second upper insulation secondary inclined surface attached to said second upper insulation surface horizontal surface at a position spatially disposed from said second upper insulation primary inclined surface and extending downwardly and outwardly therefrom, said second upper insulation secondary inclined surface being positioned in abutment with a second recess side panel for facilitating frictionally movable attachment with respect thereto;(d) a second upper insulation exterior surface extending generally vertically and facing outwardly with respect to the head-of-wall area positioned extending outwardly and above the second gypsum board construction;(2) a second lower insulation section of fire insulating material attached to said second upper insulation section at a position spatially disposed from said first lower insulation section and extending downwardly therefrom to a position in abutment with and extending over the second gypsum board construction for firestopping thereadjacent, said second lower insulation section defining a second lower insulation exterior surface extending generally vertically and facing outwardly from the head-of-wall area; C. a first cover attached to said first insulation member and positioned extending at least partially across said first upper insulation exterior surface and at least partially across said first lower insulation exterior surface for enhancing firestopping of said first insulation member; and D. a second cover attached to said second insulation member and positioned extending at least partially across said second upper insulation exterior surface and at least partially across said second lower insulation exterior surface for enhancing firestopping of said second insulation member.
