Two-piece track system
A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.
1. 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.
2. The fire-rated header track cap of claim 1 , wherein a surface of the insulating material defines a surface of the fire-rated header track cap.
3. The fire-rated header track cap of claim 1 , wherein the insulating material comprises a first fire-retardant strip on the first side portion and a second fire-retardant strip on the second side portion.
4. The fire-rated header track cap of claim 1 , wherein the insulating material comprises a heat expandable intumescent material.
5. The fire-rated header track cap of claim 1 , wherein the insulating material substantially covers an entirety of a surface of at least one of the first and second side portions of the U-shaped member.
6. The fire-rated header track cap of claim 1 , wherein the insulating material covers a portion of a surface of the middle portion of the U-shaped member that is less than an entirety of the surface of the middle portion of the U-shaped member.
7. The fire-rated header track cap of claim 1 , wherein one of the first and second side portions of the U-shaped member covers a portion of a surface of the flange portion of the U-shaped header track that is less than an entirety of the surface of the flange portion of the U-shaped header track.
8. The fire-rated header track cap of claim 1 , wherein the U-shaped member is formed from a flexible material.
9. The fire-rated header track cap of claim 1 , wherein the U-shaped member is comprised of a first piece and a second piece, wherein the first piece is comprised of the first side portion and a first portion of the middle portion, and the second piece is comprised of the second side portion and a second portion of the middle portion.
10. The fire-rated header track cap of claim 9 , wherein each of the first piece and the second piece is separately attachable to at least one of the U-shaped header track and the ceiling member.
