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.

1. A wall assembly, comprising: a header track;a bottom track;a plurality of vertical wall studs extending in a vertical direction between the bottom track and the header track;at least a first wallboard member and a second wallboard member supported by the plurality of wall studs, the first wallboard member having a first vertical side edge and the second wallboard member having a second vertical side edge, the first vertical side edge and the second vertical side edge face one another to define a vertically-extending deflection gap between the first wallboard member and the second wallboard member; anda fire-block wall component comprising a vertical fire-block support and a fire-resistant material strip, the fire-block support positioned at the deflection gap, the fire-resistant material strip attached to the fire-block support, the fire-resistant material strip extending lengthwise along and across the deflection gap, the fire-resistant material strip comprising an intumescent material that expands when exposed to elevated heat to seal the deflection gap. 2. The wall assembly of claim 1, wherein the fire-block support is a metal profile. 3. The wall assembly of claim 1, wherein the fire-resistant material strip comprises a cover layer that covers the intumescent material and includes opposing side portions positioned on opposing sides of the fire-resistant material strip, wherein the cover layer is comprised of a tape having an adhesive on an underneath surface thereof such that adhesive on the side portions secure the fire block strip to the fire-block support. 4. The wall assembly of claim 3, wherein the fire-resistant material strip further comprises a foam strip comprised of a foam material and placed side-by-side with the intumescent material, wherein the cover layer covers the foam strip and side portions of the cover layer are positioned on opposing sides of the combination of the intumescent material and the foam strip. 5. The wall assembly of claim 1, wherein the fire-block support is a wall stud. 6. A wall assembly, comprising: a first wall portion comprising a first wallboard member having a first wallboard surface and a first edge;a second wall portion comprising a second wallboard member having a second wallboard surface and a second edge, the first edge and the second edge facing one another and defining a deflection gap therebetween; anda fire-block wall component comprising at least a first layer and a fire-resistant material strip attached to the first layer, the fire-resistant material strip comprising an intumescent material that expands in response to sufficient heat to create a fire-resistant barrier;wherein the fire-block wall component is positioned to extend lengthwise along and across the deflection gap between the first wallboard member and the second wallboard member, the fire-block wall component having a U-shaped central portion and a pair of side portions extending in opposite directions from the central portion, wherein the pair of side portions are positioned on the first wallboard surface and the second wallboard surface, respectively, adjacent the deflection gap, and wherein the fire-resistant material strip is located on the central portion of the fire-block wall component such that the intumescent material seals the deflection gap when expanded. 7. The wall assembly of claim 6, wherein the central portion is positioned within the deflection gap. 8. The wall assembly of claim 6, wherein the wallboard surface is an outside surface. 9. A wall assembly, comprising: a first wall portion comprising a first wallboard member having a first wallboard surface and a first edge;a second wall portion comprising a second wallboard member having a second wallboard surface and a second edge, the first edge and the second edge facing one another and defining a deflection gap therebetween; anda fire-block wall component comprising at least a first layer and a fire-resistant material strip attached to the first layer, the fire-resistant material strip comprising an intumescent material that expands in response to sufficient heat to create a fire-resistant barrier;wherein the fire-block wall component is positioned to extend lengthwise along and across the deflection gap between the first wallboard member and the second wallboard member, the fire-block wall component having a V-shaped central portion and a pair of side portions extending in opposite directions from the central portion, wherein the pair of side portions are positioned on the first wallboard surface and the second wallboard surface, respectively, adjacent the deflection gap, and wherein the fire-resistant material strip is located on the central portion of the fire-block wall component such that the intumescent material seals the deflection gap when expanded. 10. The wall assembly of claim 9, wherein the central portion is positioned within the deflection gap. 11. The wall assembly of claim 9, wherein the wallboard surface is an outside surface. 12. The wall assembly of claim 9, wherein the first layer of the fire-block wall component is a metal profile. 13. The wall assembly of claim 9, wherein the side portions of the fire-block wall component are secured to the first wallboard surface and the second wallboard surface, respectively, by a plurality of fasteners.
