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.
Claims19
A wall assembly, comprising:
- a ceiling structure;
- a floor structure positioned opposite the ceiling structure;
- a header track attached to the ceiling structure;
- a bottom track attached to the floor structure, the bottom track including a first flange and a second flange extending from opposite edges of a web;
- at least one stud extending in a vertical direction between the bottom track and the header track;
- a wallboard attached to the at least one stud, the wallboard having a lower edge relatively closer to the floor structure and an upper edge relatively further from the floor structure, wherein a bottom wall gap is defined between the lower edge of the wallboard, the first flange of the bottom track, and the floor structure;
- an elongate, compressible foam component received within the bottom wall gap to block passage of smoke or sound through the bottom wall gap, the elongate, compressible foam component comprising a rectangular cross-sectional profile extending between a first end and a second end, the rectangular cross-sectional profile having a first side and a second side, the first side and the second side meeting at a first edge, a third side opposite the first side, and a fourth side opposite the second side, the first side and the fourth side meeting at a second edge, the rectangular cross-sectional profile extending from the first end to the second end;
- wherein the elongate, compressible foam component is positioned such that the first side faces the first flange of the bottom track;
- wherein the second side of the elongate, compressible foam component contacts the lower edge of the wallboard;
- and
- wherein the fourth side of the elongate, compressible foam component contacts the floor structure.
A wall assembly, comprising:
- a floor structure;
- a bottom track attached to the floor structure, the bottom track including a first flange and a second flange extending from opposite sides of a web;
- at least one stud having a lower end attached to the bottom track, the lower end received between the first flange and the second flange;
- a wallboard attached to the at least one stud, the wallboard having an upper edge and a lower edge;
- a bottom wall gap located between the lower edge of the wallboard and the floor structure;
- a compressible foam component having a rectangular cross section, the compressible foam component received within the bottom wall gap to block passage of smoke and/or sound, the compressible foam component comprising:
- a compressible foam profile having a first end and a second end, the compressible foam profile comprising:
- a first side;
- a second side meeting the first side at a corner, wherein the second side faces the lower edge of the wallboard;
- a third side opposite the first side;
- a fourth side opposite the second side, wherein the fourth side contacts the floor structure.
