Acoustical and firestop rated track for wall assemblies having resilient channel members

Abstract

Metal profiles used as top and bottom tracks with legs spaced apart a width to accommodate wall stud framing and resilient channel attached to at least one side of the stud framing One of the profile legs having a minimum of one return flange aiding in holding studs in place during construction and assembly life cycle. Intumescent material attached to a portion of at least one of the legs located proximate to the overhead (ceiling) structure or floor structure. Profiles are used to provide stud support, drywall edge support, fire stop protection at intersection joints, and accommodate the buildup of resilient channel used in the wall assembly All in one piece is installed at one time saving labor, materials, replacing limited caulk type materials used and eliminating installation defects typical in current construction methods

1 . A metal profile member cooperative with walls and partitions of a building including the use of resilient channel for improved sound ratings in both rated and non-rated wall assemblies in addition as a fire stop for protection of head or bottom of wall joints between gypsum wall sheathing and overhead or floor structures as well as sound dampening at said joints said invention comprising:
 A u-shaped member having a web and two legs perpendicular to the web with one of said legs having a minimum of one return flange extending inward toward the opposing leg, the distance between the opposing legs is such that it can accommodate the width of a wall framing stud and resilient channel attached to said stud with said return flange being of a distance similar to distance created by the resilient channel formed in a fashion to provide lateral support of the stud material   An embodiment of said profile having an intumescent material affixed to a portion of the leg which will be proximate to the overhead or floor structure dependent on the installation and use of the profile.   
     
     
         2 . The profile member in accordance with  claim 1  adapted to be positioned at the top of a framed wall 
     
     
         3 . The profile member in accordance with  claim 1  adapted to be positioned at the bottom of a framed wall. 
     
     
         4 . An embodiment of the profile member in accordance with  claim 1  adapted so that the second flange may extend from said first flange in a perpendicular fashion 
     
     
         5 . An embodiment of the profile member in accordance with  claim 1  having a minimum of one slot in the leg opposite the leg with said flange allowing for attachment of a fastener through the slot into the wall framing providing positive attachment while enabling the accommodation of cyclical movement of the structure. 
     
     
         6 . A wall assembly utilizing the profile member in accordance with  claim 1  at the head of the wall having a plurality of studs positioned between said leg and said return flange of opposing leg, a resilient type channel attached to the studs, wall sheathing attached to the studs on one side and the resilient channel on the opposing side of the assembly with said wall sheathing in contact with said intumescent materials. 
     
     
         7 . A wall assembly utilizing the profile member in accordance with  claim 1  at the bottom of the wall having a plurality of studs positioned between said leg and said return flange of opposing leg, a resilient type channel attached to the studs, wall sheathing attached to the studs on one side and the resilient channel on the opposing side of the assembly with said wall sheathing in contact with said intumescent materials. 
     
     
         8 . A wall assembly, comprising:
 a bottom track;   a header track confronting and vertically spaced apart from the bottom track;   a plurality of spaced apart studs vertically positioned between the bottom and header track; and   a plurality of horizontally positioned resilient channel (RC) members attached to the studs
