Abstract

A fire-rated reveal piece and wall assemblies or other assemblies that incorporate the fire-rated reveal piece, in which the reveal piece can include an intumescent or other fire-resistant material strip. The reveal can be attached adjacent to a corner, flange or leg of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the reveal piece.

First claim

What is claimed is:

1. A fire-rated wall product for inhibiting a path of the fire, heat or smoke for at least some period of time through a linear reveal gap defined between an upper wallboard member and a lower wallboard member, the product located between a stud and an interior surface of the upper and lower wallboard members, the wall product comprising:
a strap piece having a first free end and a second free end, a single bend defined by a substantially 180 degree angle between the first free end and the second free end, the bend defining a first vertical leg portion and a second vertical leg portion, the first and second vertical leg portions being formed from a single piece of material and wherein the first vertical leg portion is substantially adjacent to the second vertical leg portion,
wherein the at least some period of time is sufficient to pass a UL fire rating test.

2. The fire-rated wall product of claim 1 , wherein the wall product is attached to the upper wallboard member and the lower wallboard member by fasteners.

3. The fire-rated wall product of claim 1 , wherein the wall product is attached to the stud by fasteners.

4. The fire-rated wall product of claim 1 , wherein the first vertical leg portion has a first length defined between the bend and the first free end and the second vertical leg portion has a second length defined between the bend and the second free end, the first length and the second length being substantially the same.

5. The fire-rated wall product of claim 1 , wherein the strap piece comprises an intumescent material strip attached to at least one of the first vertical leg portion and the second vertical leg portion.

6. The fire-rated wall product of claim 1 , wherein the single piece of material is a light gauge steel material.

7. A fire-rated assembly for inhibiting a path of the fire, heat or smoke for at least some period of time through a linear reveal wall gap, the assembly comprising:
an upper wallboard member having an upper wallboard surface and an upper edge;
a lower wallboard member having a lower wallboard surface and a lower edge, the upper edge and the lower edge facing each other and defining a reveal gap therebetween; and
a strap piece having a first free end and a second free end, a single bend defined by a substantially 180 degree angle between the first free end and the second free end, the bend defining a first vertical leg portion and a second vertical leg portion, the first and second vertical leg portions being formed from a single piece of material and wherein the first vertical leg portion is substantially adjacent to the second vertical leg portion,
wherein the strap piece is positioned to extend lengthwise along and across the reveal gap, the strap piece having a central portion and a pair of side portions extending in opposite directions from the central portion, and
wherein the central portion is adjacent to the reveal gap and defined by a region of the strap piece bounded by the upper edge and the lower edge, and wherein a first one and a second one of the pair of side portions are positioned adjacent to the upper wallboard surface and the lower wallboard surface, respectively, and
wherein the at least some period of time is sufficient to pass a UL fire rating test.

8. The fire-rated assembly of claim 7 , wherein the strap piece is located between a stud and the upper and lower wallboard surfaces.

9. The fire-rated assembly of claim 7 , wherein the strap piece is attached to the upper wallboard member and the lower wallboard member by fasteners.

10. The fire-rated assembly of claim 7 , wherein the strap piece is attached to the stud by fasteners.

11. The fire-rated assembly of claim 7 , wherein the strap piece is attached to an exterior surface of the upper and lower wallboard members.

12. The fire-rated assembly of claim 7 , wherein the first vertical leg portion has a first length defined between the bend and the first free end and the second vertical leg portion has a second length defined between the bend and the second free end, the first length and the second length being substantially the same.

13. The fire-rated assembly of claim 7 , wherein the strap piece comprises an intumescent material strip attached to at least one of the first vertical leg portion and the second vertical leg portion.

14. The fire-rated assembly of claim 13 , wherein the intumescent material strip is located between the first vertical leg portion and the second vertical leg portion.

15. The fire-rated assembly of claim 13 , wherein the intumescent material strip is attached to the central portion of the strap piece.

16. The fire-rated assembly of claim 13 , wherein the intumescent material strip is attached to at least one of the first one and the second one of the pair of side portions of the strap piece.

17. The fire-rated assembly of claim 7 , wherein the single piece of material is a light gauge steel material.
