Two-piece deflection drift angle
View Patent ↗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 head-of-wall gap, the component comprising:
a fire-rated angle of a first material comprising:
an upper flange; and
a lower flange, the upper flange connected with the lower flange at a corner;
a gasket profile of a second material comprising:
an upper flange;
a lower flange, the upper flange connected with the lower flange at a corner; and
a fire-blocking strip;
wherein the lower flange of the gasket profile includes a slot, a terminal end of the lower flange of the fire-rated angle disposed within the slot to couple the fire-rated angle with the gasket profile.
2. The fire-rated component of claim 1 , wherein the upper flange of the fire-rated angle comprises a planar section.
3. The fire-rated component of claim 1 , wherein the lower flange of the fire-rated angle comprises a planar section.
4. The fire-rated component of claim 1 , wherein the upper flange of the fire-rated angle is perpendicular with the lower flange of the fire-rated angle.
5. The fire-rated component of claim 1 , wherein the first material of the fire-rated angle comprises steel and the second material of the gasket profile comprises vinyl.
6. The fire-rated component of claim 1 , wherein the lower flange of the fire-rated angle comprises a second fire-blocking strip.
7. The fire-rated component of claim 1 , wherein the upper flanges are generally aligned and the lower flanges are generally aligned.
8. The fire-rated component of claim 1 , wherein the upper flange of the gasket profile comprises a flare-out configured to seal against an overhead structure.
9. The fire-rated component of claim 1 , wherein the lower flange of the gasket profile includes an upper section and a lower section, the upper section offset from the lower section by a transition section.
10. The fire-rated component of claim 9 , wherein the upper section is aligned parallel with the lower section.
11. The fire-rated component of claim 9 , wherein an outer surface of the fire-blocking strip is aligned with the lower section of the lower flange of the gasket profile and coupled with the upper section of the lower flange.
12. The fire-rated component of claim 1 , wherein the second material is a polymer.
13. A fire-rated component for sealing a head-of-wall gap, the component comprising:
a fire-rated insert of a first material; and
a gasket profile of a second material comprising:
an upper flange;
a lower flange;
a slot portion on the lower flange; and
a fire-blocking strip on an interior side of the lower flange;
wherein the fire-rated insert is received within the slot portion of the gasket profile.
14. The fire-rated component of claim 13 , wherein the first material of the fire-rated insert comprises steel and the second material of the gasket profile comprises vinyl.
15. The fire-rated component of claim 13 , wherein the lower flange of the gasket profile includes an upper section and a lower section, the upper section offset from the lower section by a transition section.
16. The fire-rated component of claim 15 , wherein the upper section is aligned parallel with the lower section.
17. The fire-rated component of claim 13 , wherein the fire-rated insert contacts the fire-blocking strip.
18. A wall assembly comprising:
a header track configured to be coupled to a surface of an overhead structure, the header track having a web and first and second flanges extending from the web in the same direction, 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 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 overhead structure, the deflection gap being variable between a closed position and an open position;
the fire-rated component of claim 1 , wherein the upper flanges of the fire-rated angle and the gasket profile are positioned between the web and the overhead structure and the lower flanges of the of the fire-rated angle and the gasket profile are positioned at least partially within the deflection gap.
