Abstract
A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece can include 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. A fire spray material can be applied over a portion of the angle piece.
Claims12
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;
- and
- an intumescent material strip applied to an interior surface of the second flange, wherein a height of the intumescent material strip is equal to or less than about one-half a height of the second flange, wherein the intumescent material strip is spaced from an upper end of the second flange.
A fire-rated wall joint product, comprising:
- an elongated, generally L-shaped anile 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 stele piece of material;
- and
- a first intumescent material strip applied to an interior surface of the second flange, wherein a height of the intumescent material strip is equal to or less than about one-half a height of the second flange;
- and
- a second intumescent material strip applied to the fire-rated wall joint product.
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 the second flange each being planar along an entire distance between the corner and the respective free edge, the first and second flange being formed from a single piece of material;
- and
- an intumescent material applied to an interior surface of the second flange, wherein the intumescent material is spaced from an upper end of the second flange.
