Abstract
A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece includes an intumescent or other fire-resistant material strip. The angle can be attached adjacent to a corner of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement.
Claims18
A fire-rated assembly for a linear wall gap, comprising:
- a track that has a web, a first flange and a second flange, wherein the web is substantially planar and has a first side edge and a second side edge, the first flange and the second flange extend in the same direction from the first and second side edges, respectively, wherein each of the first and second flanges is substantially planar such that the track defines a substantially U-shaped cross section;
- an angle that has a first flange and a second flange, wherein each of the first flange and the second flange is substantially planar such that the angle defines a substantially L-shaped cross section, each of the first and second flanges has a free end opposite a corner of the angle;
- a heat-expandable intumescent strip attached to the angle and extending lengthwise along an outer surface of the second flange, the intumescent strip comprising a portion that extends past an outer surface of the first flange of the angle;
- wherein the first flange of the angle is positioned between the web of the track and an overhead structure with the second flange of the angle being positioned adjacent one of the first or second flanges of the track with at least a portion of the second flange contacting the one of the first or second flanges of the track.
A method of assembling a fire-rated wall joint, comprising:
- securing a header track to a ceiling;
- positioning a horizontal leg of an elongated, generally L-shaped fire-rated angle piece between the header track and the ceiling such that at least a portion of an intumescent material strip located on a vertical leg of the angle piece faces away from the header track;
- positioning upper ends of a plurality of studs into the header track;
- securing at least one wall board member to the plurality of studs such that the vertical leg of the angle piece is positioned between the at least one wall board member and the header track.
