Each tab is also preferably provided with a pair of pre-punched holes so that the tab can be fastened to other building components using standard screws.Type: ApplicationFiled: June 12, 2003Publication date: April 22, 2004Inventor: Anthony P.

Patent number: 6705056Abstract: A method and apparatus for installing backing in walls which include a first, second and third upright U-shaped stud. A first backing member has a first end, a second end, a top, a bottom, a first side and a second side. The first backing member is disposed between the first and second studs. A second backing member has a first end, a second end, a top, a bottom, a first side and a second side. The second backing member is disposed between said second and third studs. A hinge is operatively attached to the first side of the first and second backing members for permitting the second backing member to pivot with respect the first backing member between a first position wherein the first side of each of the first and second backing members are substantially in the same plane and a second position whereby the first and second backing members are not in the same plane. This permits the first backing member to be placed between a first and second adjacent vertical stud.Type: GrantFiled: October 19, 2001Date of Patent: March 16, 2004Inventor: Daniel W. Tollenaar

Patent number: 6698146Abstract: The invention provides methods, systems, and devices for installing thermal barriers in openings or gaps in or between structures such as walls, ceilings, and floors. At least one thermal barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to mold a barrier in the hole or gap.Type: GrantFiled: October 31, 2001Date of Patent: March 2, 2004Assignee: W. R. Grace & Co.-Conn.Inventors: Michael D. Morgan, Xiudong Sun, Laura A. Tennenhouse, Robert A. Wiercinski, Benita Dair, Antonio J. Aldykiewicz, Jr., Leon Bablouzian, Lawrence Shapiro

Publication number: 20040016193Abstract: An intumescent firestopping apparatus used in poke-through applications for selectively sealing an opening through a construction barrier such as a wall, floor or ceiling having cables or other penetrating members extending therethrough. The apparatus effectively seals this barrier responsive to a fire to prevent unwanted transmission of fire through conventional construction barrier areas. The apparatus includes a sleeve with two intumescent pads positioned therein. At least one of the pads has an arcuate curved central section to be biased against the other intumescent pad to define therebetween a confinement area for holding of cables centrally located therein in a dynamically adjustable sealing throat defined therebetween. These pads can be variously mounted with respect to the adjacent wall structures and one or both of the pads can be arched toward the other pad to facilitate defining of the dynamic throat for receiving cables extending therethrough.Type: ApplicationFiled: July 24, 2002Publication date: January 29, 2004Inventor: James P. Stahl

Patent number: 6658801Abstract: A portable fire curtain system to provide a cloak to cover a vented opening. When deployed it will alleviate the incoming wind, which is fueling the fire. The fire curtain is made of one sheet of a fire resistant or fire proof material that is folded and sewn together. Encapsulated within the fire curtain are 6 bars of high-tempered aluminum running laterally. Each corner of the fire curtain has holes that are drilled through the top and bottom bars. Four 5 foot cable leaders with loops, (one to each corner) will be secured to these holes. Two 40 foot ropes with snaps on all ends will be connected to these cable leaders to be used in the deployment. The ropes are packed in two rope deployment bags in order to prevent the ropes from tangling.Type: GrantFiled: July 3, 2001Date of Patent: December 9, 2003Inventors: Patrick Kilduff, Thomas Oswald

Publication number: 20030089053Abstract: A support structure such as, for example, a door jamb and a window jamb. In one embodiment, the jamb is formed from a first stud that has a web and two first flanges and a second stud with a second web and second flanges. The first stud has at least one first hole through the first web and the second stud has at least one second hole through the second web. The first and second studs are oriented such that at least one first hole is aligned with at least one second hole and a stud engager is inserted through the aligned holes to retain the studs in abutting contact to form the jamb.Type: ApplicationFiled: December 20, 2002Publication date: May 15, 2003Inventor: William L.

Patent number: 6474037Abstract: Retrofit connectors that secure together the outside sheathing and underlying structural members of wood-frame or masonry houses, preventing damage when subjected to lateral stresses from a hurricane, or transverse loads from an earthquake. The connectors have special bushings and bearing surfaces that tie the outside sheathing and underlying structural members together, but allow deflection, and transfer of energy to other structural members. Different embodiments of the connectors allow them to adapt to most wood-frame and masonry homes, and to most roof pitches.Type: GrantFiled: February 28, 2001Date of Patent: November 5, 2002Inventor: Thomas C.

Publication number: 20020157337Abstract: A draft block joist system for preventing an airflow circulation therethrough. The system comprises a first and second elongated I-beams each having continuous upper and lower flange sections with a panel member disposed therebetween. The upper and lower flange sections of the first elongated I-beam are respectively connected with the upper and lower flange sections of the second elongated I-beam. An air gap is formed between the panel members of the first and second elongated I-beams thereby. By forming the air gap, an insulation member is removably insertable therein for preventing the airflow circulation therethrough.Type: ApplicationFiled: April 27, 2001Publication date: October 31, 2002Inventor: Fred E. Hovenier
