The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

An improved flute plug for a head-of-wall assembly for fire rated wall construction beneath a fluted deck or ceiling. The improved flute plug can be friction fit within individual flute voids that run over the top of the header track. The improved flute plug can include a single piece pre-bent steel profile with fire stopping material attached thereto or contained therein. The fire stopping material can be oversized so that it will compress into the flute void over the top of the header track. The compressed fire stopping material can provide a seal against fire, smoke and/or noise through the fluted deck voids.

A fire-rated component for a fire-rated joint, such as a head-of-wall assembly, includes a fire-rated assembly include a fire-rated angle and a gasket profile. The fire-rated angle can be coupled with the gasket profile to form a single unit within the head-of-wall assembly.

A fire-rated component for a linear gap between a wall assembly and an adjacent structure. The component includes an elongate metal profile and a fire-rated board member. The elongate metal profile has a vertical leg, an upper leg and a lower leg. The upper leg extends in a first direction from an upper edge of the vertical leg. The lower leg extends in the first direction from a lower edge of the vertical leg. The fire-rated board member is positioned within a space defined by the vertical leg, the upper leg and the lower leg.

Fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, including but not limited to intumescent material. The fire-retardant material can be attached to compressible backer rods inserted within deflection gaps in the wall systems such that the fire-retardant material expands and seals gaps and/or areas between the tracks and wall components such as ceilings, floors, and drywall. Various assemblies and methods can be used to cover the deflection gap.

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.

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.

Fire block devices for application to a wall component, a wall component with a fire block device and wall assemblies including the same. The fire-block device can be a wall component that includes a fire-resistant material strip that expands in response to sufficient heat to create a fire-resistant barrier. In some applications, the fire-block wall component is positioned to extend lengthwise along and across a gap between wallboard members. The fire-block wall component may have a central portion and a pair of side portions extending in opposite directions from the central portion. The fire-resistant material may be positioned on the central portion of the fire-block device. The central portion may be positioned within the gap such that the fire-resistant material expands in response to sufficient heat to create a fire-resistant barrier.

An elongate component for placement in a wall gap and a wall incorporating such a component. The component includes a wall-face leg configured to extend along a face of a wallboard and a wall-end leg configured to extend along an end of the wallboard. The wall-end leg is oriented perpendicular to the wall-face leg. The component further includes a flexible gap portion configured to be positioned within and extend along the wall gap. The gap portion is located on an opposite side of the wall-end leg relative to the wall-face leg. A blocking element is located in a space defined by the wall-end leg and the gap portion. The blocking element is configured to block fire and/or sound within the wall gap. At least a portion of the flexible gap portion is located on an exterior side of the blocking element.

Fire or sound blocking components are configured to resist the transmission of fire, heat or sound through a gap in a wall assembly. The components can be elongate and have a profile of a consistent cross-sectional shape along the length of the component. In some arrangements, the component is configured to provide fire or sound blocking to a dynamic head-of-wall joint of a wall assembly. In other arrangements, the component is configured to provide fire or sound blocking to a reveal gap within or along an edge of a wall assembly.
