Abstract
A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.
Claims15
A fire-rated head-of-wall assembly, the head-of-wall assembly comprising:
- a header track comprising a web, a first flange and a second flange, the first flange and the second flange extending from opposite side edges of the web in a first direction, wherein each of the first flange and the second flange includes a free end;
- a plurality of studs coupled with the header track;
- at least one piece of wallboard attached to the plurality of studs;
- a unitary outer member configured to mate with the header track, the outer member comprising:
- a first side portion;
- a second side portion;
- and
- a central portion;
- wherein at least one of the first side portion, the second side portion, or the central portion comprises a fire-retardant material portion;
- wherein the outer member is disposed over the header track such that the central portion of the outer member overlays the web of the header track, the first side portion overlays the first flange and the second side portion overlays the second flange;
- and
- wherein the header track and the outer member are configured to couple to an overhead structure with the header track nested within the outer member such that the central portion of the outer member contacts the overhead structure to inhibit passage of fire, smoke, and heat.
