Patent number: 8069625Abstract: Fire resistant door, glazing, and mullion frames include intumescent material at least partially embedded in the frame adjacent the door or glazing. Trim materials are positioned over the intumescent material to prevent tampering with and damage to the intumescent material while improving the aesthetic appearance of the frame. The jamb trim has a thickness that allows heat to be transmitted to the intumescent material in the event of a fire so that the intumescent material will expand and fill a clearance space between the frame and the door or glazing. The expanded intumescent material retards the passage of heat and, by sealing the clearance space, inhibits the transmission of smoke, flames and gases from one side of the door or glazing to the other. After expanding, the intumescent material will char and solidify, which may provide an added benefit of structural support for the door or glazing.Type: GrantFiled: January 21, 2009Date of Patent: December 6, 2011Assignee: Washington Hardwoods Co., LLCInventors: Jim Harkins, John Gaydos

Patent number: 7832166Abstract: The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication.Type: GrantFiled: February 21, 2007Date of Patent: November 16, 2010Assignee: Polymer-Wood Technologies, Inc.Inventor: Evan R Daniels

Patent number: 7827759Abstract: A floor plug (10) is disclosed having a top plate (11) and a neck (12), the neck defining a top plate lip (14). To repair a bore hole (20) in a concrete floor (21) an adhesive (19) is applied to the underside of the lip (14) and the neck (12) is positioned within the bore hole (20). Once the adhesive has cured a viscous smoothing compound or concrete floor leveler is poured over the floor plug (21) and surrounding concrete floor area. If necessary, the concrete floor leveler material is smoothed to provide a generally smooth or level surface.Type: GrantFiled: January 4, 2007Date of Patent: November 9, 2010Inventor: Audrey Barnes

Publication number: 20100275539Abstract: Multi-layered, fire-barriers each sized and shaped for installation into accepting intersection-spaces formed by the spaced-intersection of at least two expansion-joint spaces that occur between two adjacent spaced structural building units, each of said expansion-joint spaces defined by a plane, said plane defined by a set of three non-colinear points with each point defined by a set of x, y, z coordinates from the same coordinate system with no two of said coordinate sets being identical. The fire-barriers are shaped for use in 2-way planar, L-shaped expansion-joint spaces, T-shaped, cross-shaped, V-shaped, and vertical/horizontal L-shaped corner expansion-joint spaces, for example, and may comprise at least one layer of: protective cloth, insulating blanket, intumescent material, and mechanically supporting layer.Type: ApplicationFiled: June 30, 2010Publication date: November 4, 2010Applicant: FIRELINE 520, LLCInventor: Alan Shaw

Patent number: 7814718Abstract: 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.Type: GrantFiled: March 18, 2010Date of Patent: October 19, 2010Inventor: James A. Klein

Patent number: 7797893Abstract: An angular flange for reinforcing and firestopping in the annulus between a structural panel such as a wall, ceiling or floor and a duct extending therethrough. The prefabricated angular flange includes a first flange leg to be secured to the duct and a second flange leg with a sealing member preferably of flexibly resilient foam which could be intumescent attached to a surface of the second leg such that when the first flange leg is secured to the duct the second flange leg can be urged against the structural panel extending therearound with the sealing member positioned between the structural panel and the second flange leg and sealing the annulus.Type: GrantFiled: May 11, 2006Date of Patent: September 21, 2010Assignee: Specified Technologies Inc.Inventors: James P. Stahl, Sr., James P. Stahl, Jr.

Patent number: 7797892Abstract: Methods and systems for plugging a hole are described. A plug may comprise a substantially tubular member having a proximal end and a distal end interconnected by a side wall, the side wall having an inward facing surface and an outward facing surface, at least the outward facing surface being substantially conformable, an adhesive disposed on the outward facing surface, a fire-resistant ring disposed substantially at one of the ends of the tubular member, and a thread disposed along the inward facing surface, the thread adapted to receive a cover.Type: GrantFiled: February 11, 2008Date of Patent: September 21, 2010Assignee: Buildings and Matters, LLCInventors: Vincent F. Cannistraro, Douglas C. Dayton, David Duncanson, Thomas J. Kosik

Publication number: 20100229483Abstract: A fire-resistant glass block including a thermal break and methods for making same. Embodiments of the glass block assembly include at least two portions filled with fire-resistant gel, wherein the at least two portions are connected using a thermal break channel. The thermal break channel improves the thermal conductions characteristics of the assembly and mitigates the potential for breakage in either glass block half unit through direct heat transfer. The glass block assembly can be made by connecting two or more glass portions using a thermal break channel and filling the connected glass block portions with fire-resistant gel.Type: ApplicationFiled: March 9, 2010Publication date: September 16, 2010Applicant: O'KEEFFE'S INC.Inventor: Jeffry Griffiths

Patent number: 7784221Abstract: A fire collar (10) including a housing defining an opening (18) and a passage (20) adapted to receive a conduit therethrough. A layer of intumescent material (43) surrounds the conduit and is supported by the housing adjacent the opening. Torsion springs (34) are mounted between the housing and the intumescent material to surround the conduit and are held in a non-operational position by fusible links (41). When the heat of a fire melts the links, each torsion spring acts in a longitudinal plane of the passage to assist the intumescent material to collapse the conduit and seal the passage against advancement of the fire.Type: GrantFiled: September 26, 2005Date of Patent: August 31, 2010Assignee: IG6 Pty LtdInventor: James Walter George Truss
