A fire-rated header track cap for sealing a horizontal wall gap, the horizontal wall gap defined by a ceiling member, a U-shaped header track and at least one wallboard, the fire-rated header track cap comprising:a U-shaped member configured to extend in a lengthwise direction of the header track, the U-shaped member having a channel defined by a middle portion, a first side portion and a second side portion, the first and second side portions extending substantially perpendicularly from opposing sides of the middle portion; and
an insulating material secured to and extending in the lengthwise direction along the U-shaped member;
wherein the U-shaped member is configured to be positioned over the U-shaped header track such that the insulating material is positioned along a web portion and a flange portion of the U-shaped header track, and
wherein the insulating material seals the horizontal wall gap by providing a seal between the web portion of the U-shaped header track and the ceiling member and between the flange portion of the U-shaped header track and the at least one wallboard.

FIRE-RATED JOINT SYSTEM

California Expanded Metal...

1. A fire-rated assembly for sealing a linear wall gap along an overhead structure, the fire-rated assembly comprising:a bottom track comprising a web, a first flange and a second flange, the first and second flanges extending in an upward direction from opposing side edges of the web, the bottom track defining an interior space between the web and the inwardly-facing surfaces of the first and second flanges;
a plurality of studs that are spaced from one another along the bottom track, each of the plurality of studs having a bottom end received within the interior space of the bottom track, each of the plurality of studs extending in a generally vertical direction from the bottom track;
a top track attached to the overhead structure, the top track comprising a web, a first flange and a second flange, the first and second flanges extending in a downward direction from opposing side edges of the web, the top track defining an interior space between the web and the inwardly-facing surfaces of the first and second flanges, wherein upper ends of each of the plurality of studs are received within the interior space of the top track;
an angle piece comprising a first flange and a second flange, the second flange oriented at an angle relative to the first flange, the first flange and the second flange being connected to one another along an edge thereby defining a corner, the first flange extending in a direction parallel with the overhead structure; the first and second flanges being formed from a non-metal material;
a heat-expandable intumescent strip attached to at least one of the first and second flanges of the angle piece, the heat-expandable intumescent strip having an activation temperature that is lower than a melting temperature of the non-metal material; and
a gasket attached to the first flange of the angle piece,
wherein the gasket contacts the overhead structure to seal the linear wall gap.
