FIRE-RATED WALL CONSTRUCTION PRODUCT

摘要

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.

主权项

1. 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 wall board is 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 backer rod positioned within the deflection gap between the upper edge of the first wall board and the horizontal ceiling element, an outer surface of the compressible backer rod at least partially coated with an intumescent material; a flexible sealant material applied to the first wall board and covering the opening of the deflection gap to enclose the compressible backer rod between the header track and the flexible sealant material.
