Fire-rated wall joint component and related assemblies

Abstract

A fire-rated component for a linear gap between a wall assembly and an adjacent structure. The component includes an elongate metal profile and a fire-rated board member. The elongate metal profile has a vertical leg, an upper leg and a lower leg. The upper leg extends in a first direction from an upper edge of the vertical leg. The lower leg extends in the first direction from a lower edge of the vertical leg. The fire-rated board member is positioned within a space defined by the vertical leg, the upper leg and the lower leg.

1 . A fire-resistant component for providing a fire-block to a head-of-wall gap of a shaft wall, comprising:
 a bent metal header component, comprising:
 a web; 
 at least one downwardly-extending leg; and 
 a pair of spaced-apart retention legs extending from opposing ends of one of the at least one downwardly-extending leg; and 
   a drywall strip positioned in a space between the retention legs.   
     
     
         2 . The fire-resistant component of  claim 1 , wherein the at least one downwardly-extending leg comprises a pair of downwardly-extending legs spaced apart on opposite sides of the web. 
     
     
         3 . The fire-resistant component of  claim 1 , wherein the drywall strip is secured to the header component. 
     
     
         4 . The fire-resistant component of  claim 1 , further comprising a C-shaped channel that receives the drywall strip, wherein the C-shaped channel is received within the space between the retention legs. 
     
     
         5 . The fire-resistant component of  claim 4 , wherein the one downwardly-extending leg comprises an intumescent strip located on an interior side of the C-shaped channel adjacent to a shaft liner. 
     
     
         6 . The fire-resistant component of  claim 1 , wherein the header component is created from a single piece. 
     
     
         7 . A shaft wall assembly comprising the fire-resistant component of  claim 1 . 
     
     
         8 . The shaft wall assembly of  claim 7 , wherein the shaft wall assembly achieves a fire rating without fire sealant provided above the shaft liner between a shaft liner and the header component. 
     
     
         9 . A fire-rated component for a linear gap between a wall assembly and an adjacent structure, the component comprising:
 an elongate metal profile comprising a vertical leg, an upper leg and a lower leg, the upper leg extending in a first direction from an upper edge of the vertical leg, the lower leg extending in the first direction from a lower edge of the vertical leg;   a fire-rated gypsum board or an insulating fire blocking material positioned within a space defined by the vertical leg, the upper leg and the lower leg; and   a fire block gasket secured to the elongate metal profile such that in use it is positioned between a wallboard of the wall assembly and the vertical leg.   
     
     
         10 . The fire-rated component of  claim 9 , wherein the gasket comprises a composite material of either open cell foam, flexible vinyl, or intumescent. 
     
     
         11 . The fire-rated component of  claim 9 , wherein a length of the gasket is between 4 to 10 feet. 
     
     
         12 . The fire-rated component of  claim 9 , wherein the gasket comprises flexible material.
