Wall joint or sound block component and wall assemblies

Abstract

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 . A fire, smoke, and/or sound blocking head-of-wall assembly, comprising:
 an overhead structure;   a header track coupled with the overhead structure including a pair of slotted flanges;   a plurality of studs coupled with the header track, an upper end of each stud coupled between the pair of slotted flanges to allow vertical movement between the plurality of studs and the overhead structure;   a wallboard coupled with the plurality of studs to form a wall;   a deflection gap located between the overhead structure and an upper surface of the wallboard, wherein the vertical movement between the plurality of studs and the overhead structure varies a height of the deflection gap between an open position and a closed position;   an elongate component configured to block the deflection gap.
