Abstract

Claims (43)

1 . A fire-rated component for sealing a perimeter building joint, the component comprising:

a first portion comprising:

an elongate first body; and

a first fire-blocking strip;

a second portion comprising:

an elongate second body, the elongate second body having an upper portion and a lower portion; and

an attachment strip coupled to the elongate second body;

an upper fire-blocking strip coupled to the elongate second body; and

a lower fire-blocking strip coupled to the elongate second body;

wherein the first portion is coupled to the second portion, and wherein the attachment strip is configured, in use, to couple the fire-rated component to a wall assembly, an adjacent structure, or both.

2 . The fire-rated component of claim 1 , wherein the attachment strip is a double-sided tape.

3 . The fire-rated component of claim 1 , wherein a first material of the elongate first body comprises steel and a second material of the elongate second body comprises vinyl.

4 . The fire-rated component of claim 1 , wherein the upper fire-blocking strip and the lower fire-blocking strip comprise intumescent material.

5 . The fire-rated component of claim 1 , wherein the attachment strip is configured to contact an adjacent structure in use.

6 . The fire-rated component of claim 1 , wherein the upper fire-blocking strip and the lower fire-blocking strip are located at a spaced-apart position relative to each other.

7 . The fire-rated component of claim 1 , wherein the first fire-blocking strip is at least partially located between the upper fire-blocking strip and the lower fire-blocking strip with the first portion coupled to the second portion.

8 . The fire-rated component of claim 1 , wherein the fire-rated component is configured to be coupled to the wall assembly by a fastener.

9 . The fire-rated component of claim 8 , wherein the fastener is a screw.

10 . The fire-rated component of claim 1 , wherein a combined width of the first fire-blocking strip, the upper fire-blocking strip, and the lower fire-blocking strip is configured to equal approximately half of a maximum width of a deflection gap for which the fire-rated component is configured for use.

11 . The fire-rated component of claim 1 , wherein the first body is aligned in a generally vertical orientation generally parallel with the second body when the first portion is coupled to the second portion.

12 . A wall assembly comprising:

a header track configured to be coupled to a surface of an overhead structure, the header track having a web, first flange, and a second flange, the first flange and the second flange extending from the web in a same direction;

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 attachment strip contacts the overhead structure; and

wherein a lower end of the fire-rated component is positioned at least partially within a space between the wallboard and the first flange of the header track.

13 . The wall assembly of claim 12 , wherein the fire-rated component breaks into a top section and a bottom section in response to heat.

14 . The wall assembly of claim 12 , wherein the fire-rated component breaks into a top section and a bottom section allowing an intumescent material to expand towards a center of the deflection gap.

15 . A fire-rated component for sealing a head-of-wall gap, the component comprising:

a first portion comprising:

an elongate first body; and

a first fire-blocking strip;

a second portion comprising:

an elongate second body, the elongate second body having an upper portion and a lower portion;

an attachment strip coupled to the elongate second body;

an upper fire-blocking strip, and a lower fire-blocking strip, the upper fire-blocking strip and the lower fire-blocking strip coupled to the elongate second body, wherein the upper fire-blocking strip and the lower fire-blocking strip comprise intumescent material;

wherein the first portion is coupled to the second portion, and wherein the attachment strip is configured, in use, to couple the fire-rated component to a wall assembly, an overhead structure, or both.

16 . The fire-rated component of claim 15 , wherein the attachment strip is a double-sided tape.

17 . The fire-rated component of claim 15 , wherein a first material of the elongate first body comprises steel and a second material of the elongate second body comprises vinyl.

18 . The fire-rated component of claim 15 , wherein the head-of-wall gap is 4 inches.

19 . The fire-rated component of claim 15 , wherein the attachment strip is configured to contact the overhead structure in use.

20 . The fire-rated component of claim 15 , wherein the upper fire-blocking strip and the lower fire-blocking strip are located at a spaced-apart position relative to each other.
