20110252743 | Bolted Steel Connections with 3-D Jacket plates and Tension Rods - This new versatile steel connection has three unique features: (1) utilizes three dimensional connection plates in a simple and consistent manner, and is suitable for all possible connection type that is made of steel W-sections; (2) uses through the depth steel rods, coupled with typical web stiffeners to transfer shear and bending moment across the connection. The shear transfer mechanism is similar to stirrups in reinforced concrete beams; (3) all components and parts can be prefabricated in shop, and conveniently bolted together at field. The merits of the connections include higher strength and ductility, stronger yet simpler connections, higher quality, small components for easy storage and transportation. In one word, it eliminates all of the inherent drawbacks and problems of conventional bolted and/or welded connections. | 10-20-2011 |
20120011805 | STEEL AND WOOD COMPOSITE STRUCTURE WITH METAL JACKET WOOD STUDS AND RODS - A composite member provides support to a structure. A wooden core of the composite member has a perimeter and a length. The wooden core provides support to the structure. A metal jacket is attached to the perimeter of the wooden core of the composite member and spans the entire length. The metal jacket provides also support to the structure. Furthermore, the interaction between the wooden core and the metal jacket provide a combination of strength that surpasses the sum of individual strengths. | 01-19-2012 |
20120298943 | Composite Guardrail Posts and Composite Floor I-Joist - The first product is Composite Guardrail Post (CGP). CGP is designed overcome all these drawbacks by substituting standard timber posts with metal jacket composite posts. The second product is Composite Floor Joist (CFI). The current invention (CFI) is similar to TJI in concept, but uses all composite material for both flanges and webs. Also, the connections between flange and web are much stronger, enabling the development of composite actions to the fullest extent. | 11-29-2012 |
20130160398 | COMPOSITE I-BEAM MEMBER - A composite steel I-beam member. The member includes confined top and bottom flanges, and a composite laminated web. The confined flange comprises a wooden core and a metal jacket wrapped around an outer perimeter of the wooden core. The overall load carrying capacity of the composite I-beam is significantly increased through a list of composite actions occurring in the individual components and their connections. Most importantly, a two-way lateral interaction can be normal to the interface between the metal jacket and the wooden core and provide an amount of compressive support to the top flange surpassing the sum of amount of support provided by the metal jacket and the wooden core when being used separately. | 06-27-2013 |
20130239512 | STEEL AND WOOD COMPOSITE STRUCTURE WITH METAL JACKET WOOD STUDS AND RODS - A composite member provides support to a structure. A wooden core of the composite member has a perimeter and a length. The wooden core provides support to the structure. A metal jacket is tightly wrapped to an optimum circumferential pre-stress around the entire perimeter of the wooden core of the composite member and spans the entire length. The metal jacket provides also support to the structure. Furthermore, the interaction between the wooden core and the metal jacket provide a combination of strength that surpasses the sum of individual strengths. | 09-19-2013 |
20140083046 | BOLTED STEEL CONNECTIONS WITH 3-D JACKET PLATES AND TENSION RODS - A three-dimensional jacket-plate connector connects at least two members. Each member comprises wide-flanged steel I-beam section. The jacket-plate connector comprises first and second three-dimensional jacket plates. | 03-27-2014 |
20140182234 | BOLTED STEEL CONNECTIONS WITH 3-D JACKET PLATES AND TENSION RODS - A three-dimensional jacket-plate connector connects at least two members. The jacket-plate connector comprises first and second three-dimensional jacket plates. Each jacket plate comprises a single continuous side web and segments of combined flanges perpendicular to, and located around the perimeter of, the side web. With all interior flanges notched out, the side web and perimeter flanges envelopes a void interior space without obstacles against accommodation of I-beam members installed from all directions. | 07-03-2014 |
20140182235 | BOLTED STEEL CONNECTIONS WITH 3-D JACKET PLATES AND TENSION RODS - A three-dimensional jacket-plate connector connects at least two members. Each member comprises wide-flanged steel I-beam section. The jacket-plate connector comprises first and second three-dimensional jacket plates. | 07-03-2014 |
