Abstract
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.

A fire-blocking bead element to provide a fire-rated seal to a gap of a wall assembly, the fire-blocking bead element comprising:
- an L-shaped profile structure, comprising:
- a first leg, the first leg comprising a free edge portion and an attachment portion, the first leg configured to extend along an outward-facing surface of a wall board of the wall assembly in use;
- and
- a second leg, the second leg comprising a first surface and a second surface opposite the first surface, wherein the second leg is coupled to the first leg at the attachment portion of the first leg to form a corner of the profile structure, wherein the second leg is configured to be located between an edge of the wall board and an adjacent structure in use;
- a gasket element positioned on the first surface of the second leg and configured to contact the adjacent structure in use, wherein the gasket element is compressible to conform to an irregular surface of the adjacent structure, and the gasket element is spaced away from the corner of the profile structure;
- and
- a fire blocking material strip located on the second surface of the second leg and configured to expand in response to heat, wherein the fire blocking material strip comprises a first side and a second side opposite the first side, wherein the first side is coupled to the second leg and the second side is configured to contact the edge of the wall board in use.
A fire-rated wall assembly comprising:
- a wall board;
- an adjacent structure, the adjacent structure spaced from the wall board to form a gap;
- a fire-blocking bead element, the fire-blocking bead element comprising:
- a profile structure, comprising:
- a first leg, the first leg comprising a first end and a second end opposite the first end, the second end including a terminal free edge, wherein the first leg is located along an outward-facing surface of the wall board of a wall;
- and
- a second leg, the second leg comprising a first surface and a second surface opposite the first surface, wherein the second leg is coupled to the first leg to form a generally L-shaped structure in cross-section having a corner, wherein the second leg is located between an edge of the wall board and the adjacent structure;
- a gasket element positioned on the first surface of the second leg and disposed within the gap, wherein the gasket element is compressible to engage with the adjacent structure to seal across the gap;
- and
- a fire blocking material strip located on the second surface of the second leg and configured to expand in response to heat, wherein the fire blocking material strip comprises a first side and a second side opposite the first side, wherein the first side of the fire blocking material strip is connected to the second leg and the second side of the fire blocking material strip contacts the edge of the wall board.
