20100170172 | HEAD-OF-WALL FIREBLOCK SYSTEMS AND RELATED WALL ASSEMBLIES - A fire retardant head-of-wall assembly configured to seal a linear head-of-wall construction joint or gap when exposed to a heat source such as a building fire is disclosed. The inventive fire retardant head-of-wall assembly comprises a header track having an elongated intumescent strip affixed lengthwise on at least one of the outer sidewall surfaces of the header track and above a centrally located and outwardly protruding lengthwise corrugated groove. The intumescent strip comprises expandable graphite and a fire retardant (C | 07-08-2010 |
20100186325 | HEAD-OF-WALL FIREBLOCK SYSTEMS AND RELATED WALL ASSEMBLIES - A fire retardant head-of-wall assembly configured to seal a linear head-of-wall construction joint or gap when exposed to a heat source such as a building fire is disclosed. The inventive fire retardant head-of-wall assembly comprises a header track having an elongated intumescent strip affixed lengthwise on at least one of the outer sidewall surfaces of the header track. The intumescent strip comprises expandable graphite and a fire retardant (C | 07-29-2010 |
20110099928 | DEFLECTION AND DRIFT STRUCTURAL WALL ASSEMBLIES - Metal framing system composed of stud and track profiles having preformed slots which allow system to accommodate for vertical deflection and horizontal drift/adjustment. Embodiment of the system also used to create protection of fire rated joints in rated wall partitions. | 05-05-2011 |
20110113710 | HEAD-OF-WALL FIREBLOCK SYSTEMS AND RELATED WALL ASSEMBLIES - The invention disclosed herein is directed to a fire retardant head-of-wall assembly configured to seal a linear head-of-wall construction joint or gap when exposed to a heat source such as a building fire. The inventive fire retardant head-of-wall assembly comprises a header track having an elongated intumescent strip affixed lengthwise on at least one of the outer sidewall surfaces of the header track. When exposed to a heat source such as a building fire, the intumescent strip is able to expand so as to at least partially fill the head-of-wall construction joint or gap; and in so doing, retard or prevent the spread of smoke and fire. The inventive fire retardant head-of-wall assembly has been certified as complaint with respect to Underwriters Laboratories, Inc.'s standards set forth in its Tests for Fire Resistance of Building Joint Systems UL 2079. | 05-19-2011 |
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 |
20110167742 | HEAD-OF-WALL FIREBLOCK SYSTEMS AND RELATED WALL ASSEMBLIES - A fire retardant head-of-wall assembly configured to seal a linear head-of-wall construction joint or gap when exposed to a heat source such as a building fire is disclosed. The inventive fire retardant head-of-wall assembly comprises a header track having an elongated intumescent strip affixed lengthwise on at least one of the outer sidewall surfaces of the header track and above a centrally located and outwardly protruding lengthwise corrugated groove. The intumescent strip comprises expandable graphite and a fire retardant (C | 07-14-2011 |
20110185656 | FIRE RETARDANT COVER FOR FLUTED ROOF DECK - A fire retardant cover is disclosed herein for covering a ceiling-side recess of a fluted roof deck and for providing a flat surface for installation of a head-of-wall track (associated with a steel stud wall assembly). The fluted roof deck has an undulating bottom surface that defines a plurality lengthwise recesses corresponding to a plurality of ceiling-side flutes of the fluted roof deck. The fire retardant cover is substantially flat and configured to sealingly cover at least one of the plurality of lengthwise recesses. The fire retardant cover comprises a piece of sheet metal bent to define first and second upwardly extending protrusions. The protrusions are spaced apart from each other by a substantially flat web section and have laterally facing outer top surfaces matched to sealingly contact lengthwise bottom surfaces of one of the plurality of recesses of the fluted roof deck when the fire retardant cover is installed. | 08-04-2011 |
20110214371 | OFFSET LEG FRAMING ELEMENT FOR FIRE STOP APPLICATIONS - The invention disclosed herein is directed to an offset leg framing element for use in a fire rated assembly and comprises: a web section having opposing edges; a pair of outwardly extending sidewalls integrally connected to the web, wherein the sidewalls are substantially parallel and confront each other. In addition, at least one laterally extending ledge section is integrally connected to one of the pair of outwardly extending sidewalls; and at least one downwardly extending leg is integrally connected to the at least one ledge section. The offset leg framing element may be characterized in that the ratio the sidewall height (h | 09-08-2011 |
20120297710 | CONTROL JOINT BACKER AND SUPPORT MEMBER ASSOCIATED WITH STRUCTURAL ASSMEBLIES - The present invention is directed to a profile used to support fire retardant and or wall sheathing behind opposing wall sheathing edges, horizontally at head of walls, and behind control/reveal joint profiles. The profiles are shaped to support wall sheathing, intumescent stopping, and fire rated “rips” of wall sheathing and work in a manner that allows protection or support of intersecting opposing drywall edges. | 11-29-2012 |
