Patent number: 8375661Abstract: A deck pan assembly for receiving and supporting concrete that is utilized as a floor system in a building. The deck pan assembly comprises a plurality of deck pans with each deck pan including a bottom and an upturned edge. The deck pans are disposed in side-by-side relationship and spaced such that the turned up edges of two deck pans lie adjacent each other and form a connecting structure that permits the two deck pans to be connected together. Further the assembly includes an elongated stiffening connector extending along the connecting structure and at least partially covering the turned up edges that form the connecting structure. The elongated stiffening connector includes a pair of spaced apart sides, and the connecting structure, formed by the upturned edges of two deck pans, is inserted between the spaced apart sides such that the spaced apart sides extend downwardly adjacent outer surfaces of the connecting structure.Type: GrantFiled: April 15, 2011Date of Patent: February 19, 2013Assignee: The Steel Netork, Inc.Inventors: Edward R. diGirolamo, John C.

Publication number: 20130019545Abstract: A building includes a connection between an engineered wood load bearing element of the building such as a column, beam, or load bearing panel, and another load bearing element or a foundation of the building. At least one tendon ties the load bearing elements or the load bearing element and the foundation together. One or more energy dissipaters, replaceably connected between the load bearing element and/or the foundation, absorb energy when a loading event causes relative movement of the connection. The engineered wood element may be a laminated veneer lumber element, a parallel strand lumber element, or a glue laminated timber element, for example. Typically all of the load bearing elements of the building will be engineered wood elements. The building may be single or multi-storey. The building system enables lightweight low cost buildings, with energy dissipaters which may be replaced after extreme loading. The building may be prefabricated.Type: ApplicationFiled: May 15, 2012Publication date: January 24, 2013Inventors: Andrew Buchanan, Stefano Pampanin, Allesandro Palermo

Patent number: 8333047Abstract: The invention therefore proposes an anchorage unit for anchoring at least one prestressing member, capable of being tensioned, onto a structural component to be strengthened or repaired by additional prestressing. The anchorage unit includes means of fixing onto the structural component and means of anchoring the prestressing member located adjacent to a first side of the anchorage unit oriented towards a regular section of the prestressing member. The fixing means are located adjacent to a second side, opposite the first side, of the anchorage unit, which is so provided that it may be put into traction when the prestressing member is tensioned.Type: GrantFiled: September 23, 2011Date of Patent: December 18, 2012Assignee: Freyssinet International (STUP)Inventors: Jean-Francois Nieto, Christian Tourneur

Publication number: 20120311945Abstract: A precast composite flooring system utilizes girders and floor panels having steel lower structures placed in tension and concrete upper structures places in compression. Openings through a stem wall allow ducts, pipes, and conduits to be run therethrough. The system provides reduced weight over conventional precast or pour in place systems, allowing further reduction in the weight and size of other building components. The floor deck does not use tensioning strands, allowing openings to be formed at nearly any stage of construction and with reduced concern over cutting steel reinforcement. The floor panels and girders bolt together and bolt to a steel column frame, allowing for more efficient assembly.Type: ApplicationFiled: April 20, 2012Publication date: December 13, 2012Inventors: David H. Platt, John E. Charchenko, Darly G. Hodgson, Russell J. Platt

Publication number: 20120266552Abstract: A hollow column having a wall surrounding an inner space is erected. Pre-stressing cables comprising tendons and two cable terminations are pre-assembled. Each tendon is contained in a respective jacket with a protective substance. Each cable termination comprises a block for anchoring each tendon of a pre-stressing cable, a chamber filled with a protective substance on a rear side of the block and a sealing system closing the chamber opposite the block. Each tendon of the pre-stressing cable extends through the sealing system and has its jacket interrupted in the chamber. The pre-assembled pre-stressing cables are installed in the inner space of the hollow column, with the two terminations of each cable bearing against abutment portions provided at the upper and lower parts of the column. The pre-stressing cables can then be tensioned.Type: ApplicationFiled: December 22, 2010Publication date: October 25, 2012Inventors: Alain Huynh Tong, Benoît Melen

Patent number: 8286309Abstract: In one form, the cable termination has a tubular body with an opening into which an end of the median barrier cable is inserted. A wedge gripper includes three sections for gripping the end of the median barrier cable within the tubular body. The wedge gripper has a tapering outer surface that mates with a tapered inner surface of the tubular body and has a toothed inner diameter. A threaded cap is screwed to an end of the tubular body opposite from the cable opening, such that the threaded cap forces the tapering outer surface of the wedge gripper axially against the tapered inner surface of the tubular body to force the toothed inner diameter of the wedge gripper to contract against three lobes of the median barrier cable to grip the median barrier cable.Type: GrantFiled: June 10, 2009Date of Patent: October 16, 2012Assignee: Actuant CorporationInventor: Stanley A.

Patent number: 8276333Abstract: An assembly and method for anchoring a wall frame to the foundation of a building utilizes an anchor member which can be threaded upon a threaded shank which is connected to and extends upwardly from the foundation, a cable, a first cable vice which is connectable to one end of the cable and being anchorable to a top member of the wall frame which is positioned upon the foundation, a second cable vice which is connectable to the other end of the cable, and a cap member. The second cable vice is anchorable to the cap member, and the cap member is connectable to the anchor member so that when the cable is anchored between the top member of the wall frame and the cap member by way of the first and second cable vices, the cap member can be connected to the anchor member to thereby tension the cable between the top member of the wall frame and the foundation.Type: GrantFiled: September 2, 2008Date of Patent: October 2, 2012Inventors: T.
