Cold-Formed Steel Joists
US Patent:
2006005, Mar 16, 2006
Filed:
Jan 7, 2003
Appl. No.:
10/500833
Inventors:
Dennis Watson - Oklahoma City OK, US
Maury Golovin - Columbus MS, US
Patrick Toney - Oklahoma City OK, US

Patrick Toney - Oklahoma City OK, US
International Classification:
E04C 3/02
US Classification:
052693000
Abstract:
A metallic joist is provided comprising cold-formed top and bottom chords, and cold-formed metallic truss web members arranged in a vertical and diagonal fashion shop welded to the chords. End connections, or “seats” are each shop welded to the top chord and to one of the webs. Each seat comprises a pair of vertical metallic planes that act as shear plates, welded to and extending outwardly and upwardly of the end portion of the top chord of the joist, and portions extending horizontally either side of the chord and punched with holes for easy field bolting to beams or other supporting elements. Each of the chords comprises a planar base and a pair of legs. Each leg comprises a chamfered portion extending downward and outward from one edge of the base at an acute angle to the horizontal; e.g., about 45 degrees, for stiffening the longitudinal edges of the base, to accommodate axial and moment forces. An upper vertical portion, perpendicular to the base, extends downward from a lower end of the chamfered portion to provide a planar width of material to accommodate axial and moment forces. An inwardly recessed portion parallel to the base extends towards the chord's center line from a lower end of the upper vertical portion; and an attachment portion, perpendicular to the base, extends downward from an inner end of the inwardly recessed portion. The inventive chord imparts the joist of the present invention with enough strength and stiffness to span up to 100-foot lengths.
Roof Panel Module Gauge
US Patent:
5129151, Jul 14, 1992
Filed:
Dec 26, 1991
Appl. No.:
7/813576
Inventors:
Kwon S. Kim - Oklahoma City OK

Assignee:
Robertson-Ceco Corporation - Pittsburgh PA
International Classification:
G01D 2100, B25B 120
US Classification:
33613
Abstract:
A module gauge is described for moduling the next-to-be-erected roof panel to conform its actual width with the design modular width by compressing or expanding the roof panel as needed. Conformation of the panel widths results in a weathertight roof structure.
Torsional Braces
US Patent:
8393126, Mar 12, 2013
Filed:
Apr 22, 2009
Appl. No.:
12/428296
Inventors:
Dennis P. Watson - Oklahoma City OK, US
Assignee:
Building Concepts, Ltd. - Oklahoma City OK
International Classification:
E04C 3/00
US Classification:
52696, 52643, 52692, 52712
Abstract:
A method and apparatus for preventing twisting of at least one purlin. A roof construction has purlins extending between support beams to provide extra stability for the roof. To prevent purlins from twisting, a torsional brace is provided. A beam of the torsional brace extends between two of the purlins. A static clip is connected to a purlin, and a pin is used to secure one end of the beam to the clip. The other end of the beam can be similarly clipped to another purlin, or alternatively, the other beam can be bolted to the purlin.
