FIRE RATED WALL STRUCTURE

摘要

A fire rated wall structure includes a channel-shaped top track and bottom track each having male protrusions formed along their side walls. The wall structure further includes at least one stud member interconnecting the top and bottom tracks. The stud member comprises a stationary portion and a slip extension slidably nested within the stationary portion. Female recesses are formed in a terminus end of each of the slip extension and stationary portion and are adapted to nest with male protrusions of the top and bottom tracks. A slot formed within the slip extension accommodates fasteners initiated from a panel member and which passes through the stationary portion side wall and extends into the slot to allow relative sliding motion between the slip extension and the stud member. A top overcap disposed in overlapping relation to the top track includes a male protrusion for slidingly bearing against the panel member.
