Abstract

Fire block devices for application to a wall component. The fire-block device can be a wall component that includes a fire-resistant material strip that expands in response to sufficient heat to create a fire-resistant barrier. In some applications, the fire-block wall component is positioned to extend lengthwise along and across a gap between wallboard members. The fire-block wall component may have a U-shaped central portion and a pair of side portions extending in opposite directions from the central portion. The fire-resistant material may be positioned on the central portion of the fire-block device. The central portion may be positioned within the gap such that the fire-resistant material expands in response to sufficient heat to create a fire-resistant barrier.

First claim

What is claimed is:

1. A fire-rated assembly for a linear wall gap, comprising:
a horizontal support structure;
a plurality of vertical wall studs;
a track for receiving the wall studs, the track connected to the horizontal support structure, the track comprising a web, a first flange and a second flange, the first and second flanges extending in the same direction from opposite edges of the web, the web and each of the first and second flanges forming a corner of the track at the opposite edges of the web;
at least one wall board supported by the wall studs, wherein the wall studs and the wall board are movable relative to the track, wherein the wall board is spaced apart from the horizontal support structure to define a deflection gap between an upper edge of the wall board and the horizontal support structure; and
an elongate fire-block wall component attached to the track and extending along the deflection gap, the elongate fire-block wall component comprising:
a fire-resistant material strip; and
a cover layer secured to and covering the fire-resistant material strip, the fire-resistant material strip having a first side surface and a second side surface, the first side surface facing the track and the second side surface facing away from the track;

wherein a first portion of the fire-resistant material strip is positioned between the web of the track and the horizontal support structure and a second portion of the fire-resistant material strip is positioned between the first flange of the track and the wall board, and wherein the cover layer is secured to and covers the second side surface.

2. The fire-rated assembly of claim 1 , wherein the fire-resistant material strip comprises an intumescent material that expands in response to sufficient heat to create a fire-resistant barrier.

3. The fire-rated assembly of claim 1 , wherein the elongate fire-block wall component is secured to the track by an adhesive.

4. The fire-rated assembly of claim 3 , wherein the adhesive is provided on a surface of at least one of the fire-resistant material strip and the cover layer.

5. The fire-rated assembly of claim 4 , wherein the adhesive is covered by a removable protective layer.

6. The fire-rated assembly of claim 4 , wherein the cover layer is adhered to at least one of the web and the first flange.

7. The fire-rated assembly of claim 4 , wherein the fire-resistant material strip is adhered to at least one of the web and the first flange.

8. The fire-rated assembly of claim 1 , wherein the elongate fire-block wall component is wrapped over the corner between the first flange and the web.

9. The fire-rated assembly of claim 1 , wherein the first portion of the fire-resistant material strip covers only a portion of the web.

10. The fire-rated assembly of claim 1 , wherein the second portion of the fire-resistant material strip covers only a portion of the first flange.

11. The fire-rated assembly of claim 1 , wherein the cover layer comprises a plastic material.

12. The fire-rated assembly of claim 1 , wherein the fire-resistant material strip is sandwiched between the cover layer and the track.

13. The fire-rated assembly of claim 1 , the cover layer further comprising a side portion extending beyond an edge of the fire-resistant material strip, wherein the side portion is adhered to the web.

14. A fire-rated assembly for a linear wall gap, comprising:
a horizontal support structure;
a plurality of vertical wall studs;
a track for receiving the wall studs, the track connected to the horizontal support structure, the track comprising a web, a first flange and a second flange, the first and second flanges extending in the same direction from opposite edges of the web, the web and each of the first and second flanges forming a corner of the track at the opposite edges of the web;
a first wall board supported by the wall studs on a first side of the stud and a second wall board supported by the wall studs on a second side of the stud opposite the first side, wherein the wall studs and the first and second wall boards are movable relative to the track, wherein each of the first and second wall boards are spaced apart from the horizontal support structure to define a first deflection gap and a second deflection gap on a respective one of the first and second sides of the wall studs between respective upper edges of the first and second wall boards and the horizontal support structure; and
a first elongate fire-block wall component and a second elongate fire-block wall component attached to the track, the first and second elongate fire-block wall components extending along a respective one of the first and second deflection gaps, each of the first and second elongate fire-block wall components comprising:
a fire-resistant material strip; and
a cover layer secured to and covering the fire-resistant material strip, the fire-resistant material strip having a first side surface and a second side surface, the first side surface facing the track and the second side surface facing away from the track;

wherein each of the first and second elongate fire-block wall components comprises a first portion of the fire-resistant material strip positioned between the web of the track and the horizontal support structure and a second portion of the fire-resistant material strip positioned between a respective one of the first and second flanges of the track and the wall board, and wherein the cover layer is secured to and covers the second side surface.

15. The fire-rated assembly of claim 14 , wherein the cover layer of each of the first and second elongate fire-block wall components further comprises a side portion extending beyond an edge of the fire-resistant material strip, wherein the side portions cover only a portion of the web.

16. The fire-rated assembly of claim 15 , wherein the side portions of the cover layers of the first and second elongate fire-block wall components are separated from each other by a distance along the web.
