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.
Claims1
A fire-rated assembly for a linear wall gap 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 wall board supported by the plurality of wall studs;
- wherein the header track is attached to an overhead structure and the bottom track, wall studs and first wall board are movable relative to the header track, wherein the wall board is spaced from the overhead structure to define a deflection gap having an opening;
- a compressible foam;
- and
- a flexible sealant material.
