Abstract
Abstract A stud wall framing construction comprises a lower track; an upper track aligned with and vertically spaced from the lower track; and a plurality of vertically aligned studs positioned between the lower and upper tracks. The lower and upper end portions of the studs are positioned within the lower and upper tracks, respectively. Each of the lower and upper tracks includes a channel with opposed track sidewalls and a track base wall. The track sidewalls have a plurality of inwardly projecting track protrusions formed from the sidewalls. Each of the track protrusions on one of the sidewalls is paired with another track protrusion disposed across the opposite sidewall. The lower and upper end portions of the studs has opposed stud sidewalls and plurality of inwardly projecting stud protrusions formed from the stud sidewalls. Each of the stud protrusions on one of the stud sidewalls is paired with another stud protrusion disposed across the opposite stud sidewall. The track and stud protrusions are adapted such that each of the pair track protrusions nest into a respective pair of stud protrusions, thereby locking the studs in the tracks.
