Hanger for fire separation wall

1. A hanger for connecting a structural component to a wall adapted to have sheathing mounted thereon, the hanger comprising:

a channel-shaped portion configured to receive the structural component, the channel-shaped portion including a base configured to receive an end portion of the structural component thereon to support the structural component, the base having an upper surface configured to engage the structural component, the upper surface lying in a base plane;

a connection portion configured for attachment to the wall, the connection portion including a back flange having an upper edge, the back flange extending from the upper edge in a direction generally toward the base plane, the connection portion and channel-shaped portion being in a fixed, spaced apart relation relative to one another; and

an extension portion including first and second extension flanges extending from the channel-shaped portion to the connection portion, each extension flange being configured to extend through the sheathing, each extension flange lying in an extension flange plane, the extension flange planes being generally perpendicular to the base plane, the back flange and the channel-shaped portion defining a sheath space sized and shaped to receive the sheathing therein so that the channel-shaped portion is located on one side of the sheathing and the back flange is located on an opposite side of the sheathing when the hanger and sheathing are installed on the wall.

2. The hanger as set forth in claim 1 , wherein each of the first and second extension flanges are planar.

3. The hanger as set forth in claim 2 , wherein each of the first and second extension flanges include an edge, the first and second extension flanges arranged to extend edgewise through the sheathing.

4. The hanger as set forth in claim 2 , wherein the first and second extension flanges each include an upper free edge.

5. The hanger as set forth in claim 1 , wherein the first and second extension flanges are configured to extend through the sheathing while maintaining a 2 hour fire resistance rating of the sheathing.

6. The hanger as set forth in claim 1 , wherein a portion of the channel-shaped portion is in an opposed, spaced apart relation with the back flange.

7. The hanger as set forth in claim 1 , wherein the back flange has a front surface lying in a back flange plane and wherein the hanger further comprises a stop configured to engage the end of the structural component to space the end of the structural component from the back flange plane by a distance sized large enough to permit the sheathing to be received between the end of the structural component and the back flange plane.

8. The hanger as set forth in claim 7 , wherein the stop is configured to space the end of the structural component from the back plane by a distance sized large enough to permit two layers of ⅝ inch thick sheathing to be received between the end of the structural component and the back flange plane.

9. The hanger as set forth in claim 7 , wherein the stop comprises back panels extending toward each other.

10. The hanger as set forth in claim 1 , wherein the first and second extension flanges are parallel to one another.

11. The hanger as set forth in claim 1 , further comprising connections between the first and second extension flanges and the channel-shaped portion, locations of the connections being spaced apart from a lower end of the channel-shaped portion where the base of the channel-shaped is located.

12. The hanger as set forth in claim 1 , wherein the back flange has a front surface lying in a back flange plane and the first and second extension flanges space the channel-shaped portion from the back flange plane by a distance sized large enough to permit two layers of ⅝ inch thick sheathing to be received between the channel-shaped portion and the back flange plane.

13. The hanger as set forth in claim 1 , wherein the connection portion includes a top flange configured to attach to a top plate of the wall, the top flange extending from the back flange.

14. The hanger as set forth in claim 13 , wherein the top flange is connected to the channel-shaped portion by way of the back flange and the extension portion.

15. The hanger as set forth in claim 1 , wherein the wall is a frame wall having a top plate having a vertical dimension, and wherein the back flange has a vertical dimension greater than the vertical dimension of the top plate.

16. A hanger to connect a joist to a frame wall adapted to have sheathing mounted thereon so that an interior side of the sheathing faces the frame wall and an exterior side of the sheathing faces away from the frame wall, the frame wall including a wooden upper plate and wooden studs extending down from the upper plate, the hanger comprising:

a channel-shaped portion configured to receive the structural component, the channel-shaped portion including a base configured to receive an end portion of the structural component thereon to support the structural component and side panels extending upward from the base;

a connection portion configured for attachment to the frame wall, the connection portion including a back flange configured for engaging a vertical face of the upper plate of the frame wall, the connection portion and channel-shaped portion being in a fixed, spaced apart relation relative to one another; and

first and second extension flanges interconnecting the connection portion and the channel-shaped portion and holding the connection portion and channel-shaped portion in spaced apart relation to each other, the first and second extension flanges being configured to extend through an opening in the sheathing to the wall frame, the back flange, the first and second extension flanges and the channel-shaped portion defining a sheathing space sized and shaped to receive the sheathing therein so that the channel-shaped portion is located on one side of the sheathing and the back flange is located on an opposite side of the sheathing, the back flange being sized and arranged to at least partially block the opening in the sheathing to reduce the exposure of the wooden top plate and wooden studs to an exterior through the opening in the sheathing.

17. The hanger as set forth in claim 16 , wherein the first and second extension flanges are configured to extend through the sheathing while maintaining a 2 hour fire resistance rating of the sheathing.

18. The hanger as set forth in claim 16 , wherein the connection portion includes a top flange configured to overlie an upper surface of the top plate, the back flange extending down from the top flange.

19. The hanger as set forth in claim 18 , wherein the top flange and back flange are connected to each other by a bend.

20. The hanger as set for thin claim 19 , wherein the side panels have rearward edges lying in a rear edge plane, each of the first and second extension flanges lying in an extension flange plane, the extension flange planes being generally perpendicular to the rear edge plane.

21. The hanger as set forth in claim 16 , wherein the back flange has a front surface lying in a back flange plane and wherein the hanger further comprises a stop configured to engage the end of the structural component to space the end of the structural component from the back flange plane by a distance sized large enough to permit the sheathing to be received between the end of the structural component and the back flange plane.

22. The hanger as set forth in claim 21 , wherein the stop is configured to space the end of the structural component from the back plane by a distance sized large enough to permit two layers of ⅝ inch thick sheathing to be received between the end of the structural component and the back flange plane.

23. The hanger as set forth in claim 22 , wherein the stop comprises back panels extending toward each other.
