Wall joint or sound block component and wall assemblies
View Patent ↗An elongate component for placement in a wall gap and a wall incorporating such a component. The component includes a wall-face leg configured to extend along a face of a wallboard and a wall-end leg configured to extend along an end of the wallboard. The wall-end leg is oriented perpendicular to the wall-face leg. The component further includes a flexible gap portion configured to be positioned within and extend along the wall gap. The gap portion is located on an opposite side of the wall-end leg relative to the wall-face leg. A blocking element is located in a space defined by the wall-end leg and the gap portion. The blocking element is configured to block fire and/or sound within the wall gap. At least a portion of the flexible gap portion is located on an exterior side of the blocking element.
1. An elongate component for placement within a deflection gap between an upper surface and an end of a wallboard in a head of wall assembly, the component comprising:
a wall-face leg configured to extend along a face of the wallboard;
a wall-end leg configured to extend along a top edge of the end of the wallboard, the wall-end leg being oriented perpendicular to the wall-face leg;
a flexible gap portion configured to be positioned within and extend along the deflection gap, the flexible gap portion extending in an opposite direction from the wall-face leg on an opposite side of the wall-end leg relative to the wall-face leg, the flexible gap portion configured to flex to vary a vertical dimension as a height of the deflection gap varies between an open position and a closed position;
a blocking element located in a space defined by the wall-end leg and the flexible gap portion, the blocking element configured to be positioned within the deflection gap and block fire and/or sound within the deflection gap;
wherein at least a portion of the flexible gap portion is located on an exterior side of the blocking element.
2. The component of claim 1 , wherein the flexible gap portion comprises a single leg.
3. The component of claim 1 , wherein the flexible gap portion comprises an enclosure.
4. The component of claim 3 , wherein the enclosure comprises a pair of legs.
5. The component of claim 4 , wherein each of the pair of legs comprises a bent free end.
6. The component of claim 5 , wherein the blocking element comprises a mineral wool material.
7. The component of claim 6 , wherein the blocking element further comprises a foam material.
8. The component of claim 1 , wherein the blocking element comprises a combination of an intumescent material strip and a foam block.
9. The component of claim 8 , wherein the intumescent material strip is attached to the wall-end leg.
10. The component of claim 8 , wherein the foam block has a height that is greater than a height of the flexible gap portion.
11. The component of claim 1 , wherein the blocking element comprises a mineral wool material.
12. The component of claim 11 , wherein the blocking element further comprises a foam material.
13. A head of wall assembly defining the deflection gap, further comprising the component of claim 1 positioned in the deflection gap.
14. A method of making a component for placement in a wall gap, comprising:
forming an elongate profile comprising a first leg and a second leg that cooperate to form an L-shape in cross-section and a flexible enclosure defining an interior space, wherein the flexible enclosure comprises a pair of flexible legs;
positioning a blocking member within the interior space of the flexible enclosure; and
separating the flexible legs and inserting the blocking member into the interior space between the flexible legs.
15. The method of claim 14 , wherein the blocking member comprises a mineral wool material.
16. The method of claim 15 , wherein the blocking member further comprises a foam material.
17. An elongate component for placement within a deflection gap between an upper surface and an edge of a wallboard in a head of wall assembly, the component comprising:
a wall-face leg configured to extend along an outer face of the wallboard;
a wall-end leg configured to extend along the edge of the wallboard, the wall-end leg being oriented perpendicular to the wall-face leg;
a flexible gap portion configured to be positioned within and extend along the deflection gap, the flexible gap portion extending in an opposite direction from the wall-face leg on an opposite side of the wall-end leg relative to the wall-face leg, the flexible gap portion configured to flex to vary a vertical dimension as a height of the deflection gap varies between an open position and a closed position;
a blocking element located in a space defined by the wall-end leg and the flexible gap portion, the blocking element configured to block fire and/or sound within the deflection gap;
wherein at least a portion of the flexible gap portion is located on an exterior side of the blocking.
18. The component of claim 17 , wherein the blocking element comprises a combination of an intumescent material strip and a foam block.
19. The component of claim 17 , wherein the wall-end leg comprises an intumescent material.
20. The component of claim 18 , wherein the foam block has a height that is greater than a height of the flexible gap portion.
