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.
Claims12
A fire-rated wall deflection joint comprising:
- an inner track extending in a lengthwise direction of the deflection joint, the inner track comprising a web, a first flange and a second flange, the first and second flanges extending from the web in first direction, wherein each of the first flange and the second flange includes a free end extending in the first direction;
- an outer member comprising intumescent material and extending in a length direction, the outer member further comprising:
- a first peripheral portion;
- a second peripheral portion;
- a central portion;
- a first elongate member coupled with the central portion;
- a second elongate member coupled with the central portion, the first and the second elongate members separated by a distance along a second direction, wherein the first direction is perpendicular to the second direction;
- a plurality of studs coupled with the inner track and at least one piece of wallboard attached to the plurality of studs;
- wherein the outer member is disposed over the inner track such that the central portion overlays at least a portion of the web of the inner track, the first peripheral portion overlays the first flange and the second peripheral portion overlays the second flange;
- and
- wherein the inner track and the outer member are coupled to an adjacent structure and the first and second elongate members contact the adjacent structure to seal therewith.
