Two-piece deflection drift angle
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.
1. A fire-rated component for sealing a perimeter building joint, the component comprising:
a planar insert piece of a first material comprising an upper free end and a lower free end; and
a gasket profile of a second material comprising:
an upper portion;
a lower portion;
a middle portion connecting the upper portion and the lower portion;
at least one fire-blocking material coupled to the middle portion;
wherein the planar insert piece is secured within the gasket profile such that the upper free end of the insert piece is disposed within a cavity space in the upper portion and the lower free end of the insert piece is disposed within a cavity space in the lower portion.
2. The fire-rated component of claim 1 , wherein the first material of the insert piece comprises steel and the second material of the gasket profile comprises vinyl.
3. The fire-rated component of claim 1 , wherein the insert piece further comprises a fire blocking material.
4. The fire-rated component of claim 1 , wherein the fire-blocking material is an intumescent tape.
5. The fire-rated component of claim 1 , wherein the upper portion comprises a round top.
6. The fire-rated component of claim 1 , wherein the insert piece is aligned parallel with the middle portion in use.
7. The fire-rated component of claim 6 , wherein the insert piece contacts the fire-blocking material of the gasket profile in use.
8. The fire-rated component of claim 7 , wherein the insert piece is a flat member.
9. A wall assembly comprising:
a header track configured to be coupled to a surface of an adjacent structure, the header track having a web, a first flange and a second flange;
at least one stud coupled to the header track, an upper end of the stud located between the first and second flanges;
at least one wallboard coupled to the stud, an upper end of the wallboard overlapping the first flange of the header track;
a deflection gap formed between the upper end of the wallboard and the surface of the adjacent structure, the deflection gap being variable between a closed position and an open position; and
the fire-rated component of claim 1 , wherein the lower portion of the gasket profile is positioned between a bottom section of the first flange of the header track and the upper end of the wallboard.
10. The wall assembly of claim 9 , wherein the lower portion is coupled to the header track with a mechanical fastener.
11. The wall assembly of claim 9 , wherein the lower portion contacts the header track in use.
