A fire-stopping material for use in sandwich panels is provided, wherein the fire-stopping material comprises a resilient, porous material at least partially impregnated with an intumescent agent. A panel for an internal wall and an internal wall are also provided, comprising the fire-stopping material disposed between two substantially parallel boards, such as plaster boards. A method of providing a service penetration through an internal wall is also provided.

A firestop collar for sealing of openings, especially of line penetrations, that pass through walls or ceilings, has a frame and a block of optionally intumescent material disposed therein.

A tubular fire stop assembly for a poured concrete structure defines at least a portion of a passage through the structure during use. The assembly has a base with a tubular sleeve, both encircling and extending along the passage. A fire ring is connected to the base and has a plate with a central opening encircling the passage. An intumescent ring has inner and outer sidewalls and opposing top and bottom walls. The intumescent ring is inside the base, encircles the passage and rests on the fire ring plate. A woven, galvanized wire mesh casing extends along the inner and outer sidewalls and the top wall of the intumescent ring.

The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

A fire-rated component for a fire-rated joint, such as a head-of-wall assembly, includes an elongate body having at least a first layer, which can be in the form of a polymer profile. A second layer can be or include a foil lining and a third layer can be or include an intumescent material. The elongate body, such as the first layer, defines an air gap. The foil lining and/or the intumescent material can be positioned within the air gap. A planar lower portion of the first layer of the elongate body is positioned between a header track and a wallboard in the fire-rated joint. A non-planar upper portion of the first layer of the elongate body is positioned at least partially within a deflection gap of the wall assembly and sealingly engages the ceiling.

The present invention relates to a metal framing bracket secured between support members or secured to a single support member having lips with notches engaging the aperture of support members allowing additional bracing members to overlap the brackets or channel shapes by increasing or decreasing the bracket size and shape of the bracket.

A penetration part fireproof covering material used when a penetration part covered for fireproof is formed in a fireproof beam that is a fireproof constructional member that constitutes a wooden building, wherein the penetration part fireproof covering material is formed to have a tubular shape by stacking a plurality of gypsum board pieces (13a) formed from gypsum boards in a thickness direction and unitarily connecting the plurality of gypsum board pieces. The penetration part fireproof covering material is formed to have the tubular shape by stacking the plurality of gypsum board pieces that preferably have an annular shape and are cut out from commercially available gypsum boards having thicknesses of 9.5 mm to 25.5 mm while fixing the plurality of gypsum board pieces to each other preferably using metal fasteners such as staples, and unitarily connecting the plurality of gypsum board pieces.

An ember and flame resistant resettable automatic soffit vent includes a tray with ventilation openings formed in its floor. A mesh screen resides on the floor of the tray spanning the ventilation openings. A flat slide resides atop the screen and also has ventilation openings that match those of the tray. The slide has an open position wherein its ventilation openings align with those of the tray to allow airflow through the vent and a closed position wherein its ventilation openings are misaligned with the ventilation openings of the tray to close off airflow through the vent. The vent can be manually moved between its open and closed positions and one or more tension springs and a thermal link assembly cooperate to move the slide to its closed position if the vent is exposed to a high temperature cause by a fire very near a home. The vent also can be manually closed by a homeowner when a fire is threatening and then manually reopened when the fire threat passes without destroying the automatic closing feature of the vent.

The melting-fuse may be a non-stable container that contains compressed or vacuumed mineral wool, such as stone wool, that is attached to the fixation details between building components that must be air-permeable that must then provide sufficient fire resistance. The application includes melting-fuses. The fuse works in two parts, first it holds the compressed or vacuumed mineral wool in the desired location, without this prematurely expanding and thus interrupting the necessary air flow. The second form of the fuse is designed for the fact that this melts first in the event of fire, after which the compressed or vacuumed mineral wool expands and seals the cavity.

Through the melting of the fuse and the subsequent sealing of the detail/opening where the application is installed, the further spread of the fire through the air flow is prevented.
