| 052317000 | DRAFT STOP BETWEEN STUDS; E.G., FIRE STOP | 8 |
| 20080245009 | HORIZONTAL FIRE BARRIER SYSTEM - A modular fire barrier and method for use. The fire barrier includes numerous modules that are oriented horizontally, made up of a frame and numerous fire-resistant panels. By making the frame from tubular-shaped members, the barrier enjoys increased load-bearing ability under high temperature conditions that may compromise less robust frames. By arranging the modules to be substantially in a horizontal orientation, the frames provide sufficient support to the panels, thereby avoiding the need for additional support, such as from girts. | 10-09-2008 |
| 20080313986 | Collar for increasing T-ratings and performance of firestop systems - An assembly for cooling a penetrant from the non-fire side of a barrier and to extend the time that a firestop prevents the passage of flames and hot gases of a through penetration firestop installation. The present invention includes an encapsulation wrap that is positioned adjacent to and surrounding a penetrant or conduit. The encapsulation wrap comprises a plurality of individual coolant packages, each of which contains purified water or other appropriate coolant. An exterior banding structure is provided which is positioned adjacent to the encapsulation wrap and includes a plurality of vents to improve its heat dissipation properties and may include exterior fins. The encapsulation wrap and exterior banding are positioned and held in place by a hose clamp or other suitable attachment means. The packets of coolant are engineered to release a controlled amount of coolant when the coolant and/or penetrant achieves a predetermined temperature. | 12-25-2008 |
| 20100107532 | METHODS AND APPARATUSES FOR POSITIONING AND SECURING SAFING INSULATION - The present invention provides methods and apparatuses for securing safing insulation in the gap formed between a spandrel and a slab. Additionally, the present invention eliminates the need for stiffening tees and/or stiffening brackets. In one exemplary embodiment, the present invention utilizes a first portion of safing secured to spandrel insulation positioned in an exterior wall structure and a second portion of safing insulation positioned adjacent to the first portion of safing insulation and between the spandrel insulation and the slab. By fixedly securing the first portion of safing insulation to the spandrel insulation, any deformation of the spandrel insulation caused by the forces exerted by the compressed second portion of safing insulation on spandrel insulation results in the first portion of safing insulation moving with the spandrel insulation. | 05-06-2010 |
| 20100212243 | Lead sheet suspension stud - The present invention relates to an article of manufacture and a method of how to utilize the same in order to create a radiation leak-proof environment. The present invention further relates to a metal stud configured with two holding cavities wherein the first holding cavity and the second holding cavity are constructed so that when a lead sheet is held in the first holding cavity and wherein a lead sheet is held in the second holding cavity the lead sheets overlap, and thereby, create a radiation leak-proof metal stud system. | 08-26-2010 |
| 20110146180 | ACOUSTICAL AND FIRESTOP RATED TRACK FOR WALL ASSEMBLIES HAVING RESILIENT CHANNEL MEMBERS - Metal profiles used as top and bottom tracks with legs spaced apart a width to accommodate wall stud framing and resilient channel attached to at least one side of the stud framing One of the profile legs having a minimum of one return flange aiding in holding studs in place during construction and assembly life cycle. Intumescent material attached to a portion of at least one of the legs located proximate to the overhead (ceiling) structure or floor structure. Profiles are used to provide stud support, drywall edge support, fire stop protection at intersection joints, and accommodate the buildup of resilient channel used in the wall assembly All in one piece is installed at one time saving labor, materials, replacing limited caulk type materials used and eliminating installation defects typical in current construction methods | 06-23-2011 |
| 20120124928 | Fire Stop and Method of Use Thereof - A fire stop dimensioned to fit a selected size opening. The fire stop comprises end plates, a central shaft member retaining the end plates apart from one another, and a core between the end plates that comprises fire putty and mineral wool. The thickness and density of the mineral wool layer and/or the fire putty layer are chosen to achieve a particular fire rating within the constraints of the overall dimensional thickness of the slab. The fire stop has a low profile rendering it non-obstructing, can be inserted by a single installer from above a floor slab or into a wall, and further can be removed for inspection and/or replacement as needed. The fire putty layer swells under heat filling remaining gaps between the fire stop and the opening. | 05-24-2012 |
| 20140318064 | PRESS-ON RETAINER FOR FIRE-STOPPING SLEEVE - A press-on retainer is configured to retain a fire-stop sleeve in an opening. The retainer includes a body formed of sheet metal. The body is configured to define a concave shape, a hole in the body, and a plurality of segments extending radially from the hole. Each segment is includes an angled portion at the end of the segment that defines the hole with a diameter suitable to accept the sleeve. The angled portions are configured to allow the retainer to be pressed onto the sleeve in a first direction, and thereafter prevent the retainer from being moved in a second direction opposite the first direction. | 10-30-2014 |
| 20150113896 | FIRE BLOCK - A fire block, adapted for blocking flames and air flow from traversing between a first portion of a wall cavity and a second portion of a wall cavity and a method for installing a fire block. The fire block may include a first male tray having a shield with various other components and a female tray having a shield with various components. The male tray be received by the female tray to form a fire block. | 04-30-2015 |
