Abstract

Fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, including but not limited to intumescent material. The fire-retardant material can be attached to compressible backer rods inserted within deflection gaps in the wall systems such that the fire-retardant material expands and seals gaps and/or areas between the tracks and wall components such as ceilings, floors, and drywall. Various assemblies and methods can be used to cover the deflection gap.

Claims (38)

1. A fire-rated assembly for a wall gap comprising:

a header track;

a plurality of vertical wall studs received within the header track;

a wall board having an upper edge and supported by the plurality of wall studs;

wherein the header track is configured to be attached to an overhead structure, and the wall studs and the wall board are movable relative to the header track, wherein the upper edge of the wall board is spaced from the overhead structure to define a deflection gap having an opening;

a fire-stopping compressible foam component positioned in the deflection gap between the upper edge of the wall board and the overhead structure, the fire-stopping compressible foam component further comprising an intumescent material, a bottom surface positioned above the upper edge of the wall board, and a top surface opposite the bottom surface, wherein the top surface is configured to contact the overhead structure, and wherein the bottom surface is positioned above a vinyl material layer.

2. The fire-rated assembly of claim 1 , wherein the fire-stopping compressible foam component is configured to substantially fill the space of the deflection gap.

3. The fire-rated assembly of claim 1 , wherein the fire-stopping compressible foam component comprises open cell polyurethane.

4. The fire-rated assembly of claim 1 , wherein the fire-stopping compressible foam component defines a rectangular profile and is configured to compress in response to movement of the wall board.

5. The fire-rated assembly of claim 1 , wherein an upper portion of the wall board contacts the header track.

6. The fire-rated assembly of claim 1 , wherein the fire-stopping compressible foam component further comprises an intumescent coating.

7. The fire-rated assembly of claim 1 , wherein the fire-stopping compressible foam component further comprises an outer side surface extending between the top surface and the bottom surface and facing the opening of the deflection gap, and an inner side surface opposite the outer side surface, the inner side surface configured to contact the header track.

8. The fire-rated assembly of claim 7 , wherein the vinyl material layer is attached to the bottom surface of the fire-stopping compressible foam component and positioned between the upper edge of the wall board and the fire-stopping compressible foam component.

9. The fire-rated assembly of claim 7 , wherein the outer side surface is covered with a joint compound.

10. A fire-rated assembly for a wall gap comprising:

a header track;

a plurality of vertical wall studs received within the header track;

a wall board having an upper edge and supported by the plurality of wall studs;

wherein the header track is configured to be attached to an overhead structure, and the wall studs and the wall board are movable relative to the header track, wherein the upper edge of the wall board is spaced from the overhead structure to define a deflection gap having an opening;

a fire-stopping compressible foam component positioned in the deflection gap between the upper edge of the wall board and the overhead structure, the fire-stopping compressible foam component further comprising a bottom surface positioned above the upper edge of the wall board, and a top surface opposite the bottom surface, wherein the top surface is configured to contact the overhead structure, wherein the bottom surface is positioned above a vinyl material layer, and wherein the fire-stopping compressible foam component comprises an intumescent material layer that defines the top surface.

11. The fire-rated assembly of claim 10 , wherein the fire-stopping compressible foam component is configured to substantially fill the space of the deflection gap.

12. The fire-rated assembly of claim 10 , wherein the fire-stopping compressible foam component defines a rectangular profile and is configured to compress in response to movement of the wall board.

13. The fire-rated assembly of claim 10 , wherein the fire-stopping compressible foam component comprises open cell polyurethane.

14. A fire-rated assembly for a wall gap comprising:

a header track;

a plurality of vertical wall studs received within the header track;

a wall board having an upper edge and supported by the plurality of wall studs;

wherein the header track is configured to be attached to an overhead structure, and the wall studs and the wall board are movable relative to the header track, wherein the upper edge of the wall board is spaced from the overhead structure to define a deflection gap having an opening;

a fire-stopping compressible foam component positioned in the deflection gap between the upper edge of the wall board and the overhead structure, the fire-stopping compressible foam component further comprising a bottom surface positioned above the upper edge of the wall board, and a top surface opposite the bottom surface, wherein the top surface is configured to contact the overhead structure, wherein the fire-stopping compressible foam component further comprises an outer side surface extending between the top surface and the bottom surface and facing the opening of the deflection gap, and an inner side surface opposite the outer side surface; and

a vinyl material layer attached to the bottom surface of the fire-stopping compressible foam component and positioned between the upper edge of the wall board and the fire-stopping compressible foam component.

15. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component is configured to substantially fill the space of the deflection gap.

16. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component further comprises an intumescent coating.

17. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component defines a rectangular profile and is configured to compress in response to movement of the wall board.

18. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component is configured to substantially fill the space of the deflection gap.

19. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component comprises open cell polyurethane.

20. The fire-rated assembly of claim 14 , wherein the upper edge of the wall board contacts the header track.

21. The fire-rated assembly of claim 14 , wherein the fire-stopping compressible foam component further comprises an outer side surface extending between the top surface and the bottom surface and facing the opening of the deflection gap, and an inner side surface opposite the outer side surface, the inner side surface configured to contact the header track.

22. The fire-rated assembly of claim 21 , wherein the outer side surface is covered with a joint compound.
