A combined wooden frame support and ceiling system is provided, each support including upper and lower wooden chords and a wooden structure connecting the lower chord to the upper chord for weight bearing purposes. A gypsum wallboard batten strip is attached to the lower chord, and defining a ledge extending from each side of the lower chord. A single thickness of gypsum wallboard panels is used to create a ceiling attached to the support, each panel used to create the ceiling is made from a slurry composition including less than 5% by weight of Grade 4 vermiculite. Upon the support being assembled in the ceiling system, with a plurality of the supports, and having lengths of insulation supported by the ledges of the adjacent supports, the ceiling system resists charring by fire for at least one hour.

An aisle containment roof system includes a frame configured to be supported by two rows of racks or by the one row of racks and a wall or by a dedicated frame structure independent of the two rows of racks. The aisle containment roof system further includes a fixed perforated panel fixedly secured to the frame. The fixed perforated panel includes a pattern of openings formed therein. The aisle containment roof system further includes a movable perforated panel movably secured to the frame. The movable perforated panel has a pattern of openings corresponding to the pattern of openings of the fixed perforated panel. The aisle containment roof system further includes a mechanism configured to move the movable perforated panel relative to the fixed perforated panel to align the openings of the movable perforated panel to the openings of the fixed perforated panel.

A hanger for connecting a structural component to a wall having sheathing mounted thereon after the hanger is connected to the wall. The hanger includes a channel-shaped portion configured to receive a structural component. An extension portion extends from the channel-shaped portion and is configured to extend through the sheathing. A connection portion extends from the extension portion and is configured for attachment to the wall. The connection portion includes connector flanges configured to attach to a stud of the wall. The extension portion minimally disrupts the continuity of the sheathing to maintain the fire resistive rating of the sheathing.

Embodiments of the present invention are directed towards fire blocking apparatuses. A fire blocking apparatus for a solar panel is mounted to an underlying mounting surface. The fire blocking apparatus includes a panel support structure sized and shaped to be mounted between a solar panel and the mounting surface thereby supporting and creating a gap between at least a portion of the solar panel and the mounting surface, where at least a portion of the panel support structure comprises a heat or fire sensitive material configured to melt, deform, or warp at a predetermined temperature such that when the structure is mounted between the solar panel and the mounting surface and heated at or above the predetermined temperature, the panel support structure collapses to reduce the gap between the at least a portion of the solar panel and the mounting surface.

This application relates to I-joists which are configured to resist fire damage. Specifically, the present application relates to reinforcing I-joists with reinforcing members configured to provide structural support and/or to provide a physical barrier to fire. This may help the I-joists to maintain structural integrity during a fire and so help improve safety during evacuation of a building and during fire-fighting operations.

A prefabricated seismic isolation fire-proof and active self-cleaning bearing system and an implementation method thereof are provided. When a fire is detected, switching a switching valve to a B2 branch, and starting a water supply pump and a drainage pump; passing the water from a water reservoir through a switching valve, a water inlet elbow, a water inlet hose, and a plurality of water spray coils and ejecting the water from all conical nozzles in sequence; transporting the water settled in the water receiving tank to the water reservoir by the drainage pump; when the fire is extinguished, starting the air supply pump and the turning off the water supply pump at the same time, and switching the switching valve to the B1 branch; ejecting air from several conical nozzles at the same time by the air supply pump through the switching valve, etc.

A prefabricated seismic isolation fire-proof and active self-cleaning bearing system and an implementation method thereof are provided. When a fire is detected, switching a switching valve to a selected branch, and starting a water supply pump and a drainage pump; passing the water from a water reservoir through a switching valve, a water inlet elbow, a water inlet hose, and a plurality of water spray coils and ejecting the water from all conical nozzles in sequence; transporting the water settled in the water receiving tank to the water reservoir by the drainage pump; when the fire is extinguished, starting the air supply pump and the turning off the water supply pump at the same time, and switching the switching valve to a different branch; ejecting air from several conical nozzles at the same time by the air supply pump through the switching valve.

Wood-framed buildings, wood-framed buildings, and methods related thereto. Such a wood frame building structure includes first and second frame structures that are oriented horizontally and first and second supports between the first and second frame structures. The first frame structure is vertically spaced apart from the second frame structure and the first and second frame structures define upper and lower members, respectively, of the wood frame building structure. Each of the first and second supports have oppositely-disposed ends that are secured to the first and second frame structures, respectively. A cavity is defined by and between the first and second structures and the first and second supports, and surfaces of the first and second structures and first and second supports face and exposed within the cavity. The surfaces are entirely covered with a fire-resistant material to increase fire resistance of all of the surfaces exposed within the cavity.
