Abstract
A fire-resistance angle piece and related assemblies include at least one multi-layer portion, which can provide an insulation space and/or a sacrificial layer of the angle piece. The angle piece can comprise vent openings to a space between adjacent layers of the angle piece. In some configurations, adjacent layers of the angle piece can be sealed to one another, such as along an edge portion that can be opposite the vent openings (if present) and/or a fold of the angle piece or other closed end that creates adjacent layers. Intumescent may or may not be included on the angle piece.
Claims20
A fire-rated wall joint product, comprising:
- an elongated, generally L-shaped angle piece comprising a first flange and a second flange oriented at an angle relative to the first flange, the first flange and the second flange each having a free edge and being connected to one another along an edge that is opposite the free edges thereby defining a corner, the first flange and second flange formed from a single piece of material;
- wherein one of the first flange and the second flange comprises multiple layers of material.
A fire-rated wall assembly, 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;
- at least one wallboard;
- an elongated, generally L-shaped angle piece comprising a first flange and a second flange oriented at an angle relative to the first flange, the first flange and the second flange each having a free edge and being connected to one another along an edge that is opposite the free edges thereby defining a corner, the first flange and second flange formed from a single piece of material, wherein one of the first flange and the second flange comprises multiple layers of material;
- and
- wherein, in use, the angle piece is positioned between the track and the wallboard.
A fire-rated wall joint product, comprising:
- an elongated, generally T-shaped angle piece comprising a first flange, a second flange, and a third flange, the second flange oriented at an angle relative to the first flange and the third flange, the first flange and the third flange each having a free edge and being connected to one another along an edge that is opposite the free edges thereby defining two corners, the first flange, the second flange, and the third flange formed from a single piece of material;
- wherein the second flange comprises multiple layers of material.
A method of assembling a fire-rated wall joint, comprising:
- securing a header track to a ceiling;
- positioning a first horizontal leg of an elongated, generally T-shaped fire-rated angle piece between the header track and the ceiling;
- positioning a plurality of studs into the header track;
- securing at least one wall board member to the plurality of studs such that a first vertical leg of the angle piece is positioned between the at least one wall board member and the header track and a second vertical leg of the angle piece is positioned outward of the at least one wall board;
- and
- applying a fireblocking material to an outside surface of the second vertical leg of the angle piece.
