Benefits of technology
The present invention is a metallic box that has an open front and can be easily moved. The inside surfaces of the box and the removable back are covered with a fire blanket or mat. The box has slots in the sides which allows it to be installed over existing supply lines and can also be used for retrofit applications. The technical effect of this invention is the provision of a safe and flexible metallic box that can be utilized in various fire safety situations and can also be easily moved and installed.
Problems solved by technology
Any breaches resulting from installation of recessed fixtures cannot reduce the required fire rating of the wall or partition.
Shower valves present a difficult membrane penetration to address.
Creating a fire barrier for a shower valve penetration is difficult enough in new construction; trying to apply existing solutions in a retrofit application is not economically feasible.

Embodiment Construction
[0027]The fire barrier insert for membrane penetrations is disclosed herein with respect to exemplary embodiments. The embodiments are disclosed for illustration of the fire barrier box for membrane penetrations and a manner of making use of such barrier box and are not limiting except as defined in the appended claims.
[0028]Reference is now made to the drawings wherein like structures refer to like parts throughout. FIG. 1 depicts a fixture membrane penetration 10 within a fire barrier wall 12, with a fire barrier box 16 installed within the penetration, the fire barrier box including an inner intumescent mat liner 18 extending over the entirety of the inner side walls and a back panel 22, also lined with an intumescent mat. A shower valve 24 is shown within the fire barrier box 16, with a plurality of attached water supply lines 26 and line connectors 28. The shower valve 24 and associated plumbing hardware is presented as an example of a manner of using the present invention. The...

A fire barrier box for placement within a fixture membrane in a fire barrier wall provides a metallic side panel box of multiple box sides, each side having a slot, and a selectively attached back panel. An intumescent liner attaches to the inner side panel walls and to the interior surface of the back panel. When a fixture is received within the side panel box, the intumescent liner, and the slots cooperatively receive fixture supply lines enabling their connection with the fixture. The selective attachment of the back panel occurs once rear access to the side panel box interior is no longer required. The completed fire barrier box attaches to the stud framing, maintaining the rating protection of the fire barrier wall.
Description
RELATED APPLICATIONS[0001]The present application claims the benefit of priority under 35 USC ยง 119(e) to U.S. Provisional Application No. 62 / 486,249 filed on Apr. 17, 2017, which is incorporated by reference herein for all that it contains.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to thermal barriers and, more particularly, to fire resisting thermal barriers. More specifically, the present invention relates to fixture-receiving fire barrier boxes placed within membrane penetrations in a fire barrier wall.Description of the Related Art[0003]As part of the passive fire protection system for a building, a fire barrier wall acts to prevent or delay the spread of fire. Building codes require a specified fire resistance rating for the interior walls and ceilings of commercial buildings, depending upon their location and the nature of their use within the commercial structure. Frequently fire ratings are specified based upon duration (for example...
