Intumescent collared scab framing element

Abstract

An intumescent collared scab framing element configured to block and seal an opening positioned along a head-of-wall track (associated with static or dynamic head-of-wall framing assemblies) installed on a ceiling is disclosed. The cut-away opening of the head-of-wall track has a horizontal pipe or conduit penetrating therethrough, with the pipe or conduit being positioned along the ceiling perpendicular to the track. The flat sheet is larger than the opening and includes an upper flange. The upper flange, in turn, is configured to friction fit between the head-of-wall track and the ceiling. The flat sheet and upper flange have a downwardly extending notch sized and configured to receive the pipe or conduit (when the flange is friction fitted between the head-of-wall track and the ceiling). The collar extends inwardly or outwardly away from the flat sheet, and an intumescent strip lines the collar while an intumescent caulk seals the space therebetween.

What is claimed is: 
     
         1 . An intumescent collared scab framing element configured to block and seal an opening along a head-of-wall track installed on a ceiling, wherein the opening has a horizontal pipe or conduit penetrating therethrough, and wherein the pipe or conduit is positioned along the ceiling perpendicular to the track, comprising:
 a flat sheet section larger than the opening and having an upper flange, wherein the upper flange is configured to friction fit between the head-of-wall track and the ceiling, and wherein the flat sheet and upper flange include a downwardly extending notch sized and configured to receive the pipe or conduit when the flange is friction fitted between the head-of-wall track and the ceiling;   a collar extending inwardly or outwardly away from the flat sheet, wherein the collar is attached to the flat sheet about the notch and is sized and configured to fit about the pipe or conduit;   a solid strip of intumescent material positioned within the collar and adjacent to the pipe or conduit; and   an intumescent caulk material positioned between the strip of intumescent material and the pipe or conduit, wherein the intumescent caulk material contacts both the strip of intumescent material and the pipe or conduit.   
     
     
         2 . The intumescent collared scab framing element of  claim 1  wherein the flat sheet and the collar are both made of sheet metal. 
     
     
         3 . The intumescent collared scab framing element of  claim 2  wherein the opening and the notch are both generally U-shaped. 
     
     
         4 . The intumescent collared scab framing element of  claim 3  wherein the collar further comprises a perimeter flange that abuts and connects to the flat sheet section. 
     
     
         5 . The intumescent collared scab framing element of  claim 4 , further comprising one or more additional strips of intumescent material positioned on the exterior face of the flat sheet section and about the pipe or conduit. 
     
     
         6 . A dynamic head-of-wall framing assembly in combination with an intumescent collared scab framing element, wherein the intumescent collared scab framing element is configured to block and seal an opening along a head-of-wall track installed on a ceiling wherein the opening has a horizontal pipe or conduit penetrating therethrough, and wherein the pipe or conduit is positioned along the ceiling perpendicular to the track, comprising:
 a flat sheet larger than the opening and having an upper flange, wherein the upper flange is friction fitted between the head-of-wall track and the ceiling, and wherein the flat sheet and upper flange include a downwardly extending notch sized and configured to receive the pipe or conduit;   a collar extending inwardly or outwardly away from the flat sheet, wherein the collar is attached to the flat sheet about the notch and is sized and configured to fit about the pipe or conduit;   a solid strip of intumescent material positioned within the collar and adjacent to the pipe or conduit; and   an intumescent caulk material positioned between the strip of intumescent material and the pipe or conduit, wherein the intumescent caulk material contacts both the strip of intumescent material and the pipe or conduit.   
     
     
         7 . The dynamic head-of-wall framing assembly in combination with an intumescent collared scab framing element of  claim 6  wherein the flat sheet and the collar are both made of sheet metal. 
     
     
         8 . The dynamic head-of-wall framing assembly in combination with an intumescent collared scab framing element of  claim 7  wherein the opening and the notch are both generally U-shaped. 
     
     
         9 . The dynamic head-of-wall framing assembly in combination with an intumescent collared scab framing element of  claim 8  wherein the collar further comprises a perimeter flange that abuts and connects to the flat sheet. 
     
     
         10 . The dynamic head-of-wall framing assembly in combination with an intumescent collared scab framing element of  claim 9 , further comprising one or more additional strips of intumescent material positioned on the exterior face of the flat sheet and about the pipe or conduit.
