Fire-rated wall and ceiling system

摘要

The present application is directed toward 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, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

主权项

1. A method of assembling a fire rated metal stud frame wall and ceiling system, comprising:
providing a metal bottom track, the metal bottom track comprising a web, a first flange and a second flange, the first and second flanges extending in an upward direction from opposing side edges of the web, the bottom track defining an interior space between the web and the inwardly-facing surfaces of the first and second flanges; positioning lower ends of a plurality of metal studs into the interior space of the bottom track such that each of the plurality of studs extends in a generally vertical direction from the bottom track, the plurality of metal studs spaced from one another along the bottom track; and securing a metal top track to the ceiling, the metal top track comprising a web, a first flange and a second flange, the first and second flanges extending in a downward direction from opposing side edges of the web, the top track defining an interior space between the web and the inwardly-facing surfaces of the first and second flanges, wherein upper ends of each of the plurality of studs are received within the interior space of the top track, further comprising a first heat-expandable, intumescent material strip extending along a length of the top track on a first side thereof and a second heat-expandable, intumescent material strip extending along a length of the top track on a second side thereof, the first and second intumescent material strips attached to the top track and each having at least a first surface facing the top track and a second surface, wherein the second surface of each of the first and second intumescent material strips defines a width and the combined widths of the second surfaces of the first and second intumescent material strips is less than the width of the web of the metal top track, wherein the first and second intumescent material strips are located on the top track such that the second surface of each of the first and second intumescent material strips is compressed against the ceiling when the top track is secured to the ceiling.
