Patent number: 6931804Abstract: A novel prefabricated shearwall is disclosed with improved structural characteristics in terms of its ability to 1) transfer lateral loads to the foundation, 2) resist bending moments normally arising in conventional shearwalls between hold-down hardware and end posts or vertical framing members, 3) effectively diffuse stresses known to result in nail fatigue, and 4) reduce slippage between the bottom of the end posts and base in response to cyclic loadings. These superior properties result partly from its geometry in lower, or shear force transfer region, accompanied by thrust block/anchor rod assemblies to provide stiffness and strength over the lower portion of the end posts. Furthermore, specialized wrap-around connector plates that cover a portion of the bottom surface of these end posts also contribute to the enhanced prefabricated shearwall design.Type: GrantFiled: June 20, 2002Date of Patent: August 23, 2005Assignee: Shear Force Wall Systems Inc.Inventors: Glenn M.

Patent number: 6378260Abstract: A form tie for joining a pair of form sidewalls includes first and second vertical struts presenting planar nailing surfaces for embedding in the first and second sidewalls. A web obliquely extends between the struts and across the cavity between the laterally spaced-apart sidewalls. The web includes a top strut which slopes between the vertical struts and across the cavity. The form ties are alternately placed in alternate 180° orientations along the sidewalls such that the web extends in alternate directions across the cavity which enhances the form rigidity. Concurrently, the top web strut slopes in opposed direction to form a V-type seat for placement of a horizontal rebar within the cavity.Type: GrantFiled: July 12, 2000Date of Patent: April 30, 2002Assignee: Phoenix Systems & Components, Inc.Inventors: Jay D. Williamson, Thomas E. Whitmore, David Henney, Kelly G. Chandler, Robert D. Grove

Publication number: 20020046534Abstract: The present invention is directed to a truss system comprising first and second chords and a number of joists in bolted connection to form a load bearing structure. The first and second chords extend longitudinally in parallel alignment to form the beams upon which a load will be spread across. The first and second diagonal members of a joist are aligned at approximately 45 degree angles to the first and second chord, and perpendicularly to each other, to maximize the load bearing capabilities of the truss system. By utilizing a utility support grid to couple a first truss to a second truss, the present invention can support a load spread over a greater area.Type: ApplicationFiled: August 6, 2001Publication date: April 25, 2002Inventors: John D. Heinly, Jack E. Biersdorfer, Ihab M. Ayoub

Publication number: 20020046514Abstract: A shear wall panel for a building has a rectangular frame of vertical and horizontal members. Inside of the rectangular frame, at least four diagonal members are joined at their ends to create a multi-segmented assembly having at least three vertices and first and second ends and possibly forming a polygon, one of the at least three vertices secured to each of the vertical and an upper horizontal members, the first and second ends secured to a lower horizontal member. The members are preferably of wood and connected together with toothed plates. The panel is shear connected to a foundation or laterally stabilized wall or floor below the shear wall panel, possibly by a bolt between the foundation or laterally stabilized wall or floor below the shear wall panel and the intersections between the vertical members and the diagonal members. Upper strap connectors attach the upper horizontal member to a roof, floor or wall of the building.Type: ApplicationFiled: June 15, 2001Publication date: April 25, 2002Inventor: Thomas Leung

Publication number: 20020029538Abstract: The present invention is a steel floor truss system for buildings, especially residential homes, wherein the truss includes a steel top member, or chord, extending between two vertical bearings. Typically, a vertical bearing is an inside (interior) or outside (foundation wall) steel stud, in which case, the steel chord is fastened to the top of the vertical steel stud, typically via a metal plate which overlaps and is screwed to both the chord and the stud. In some embodiments, however, a vertical bearing may be a concrete or cinder block (CMU) wall, and, in this case, the steel chord is fastened to the concrete or cinder block wall, for example, by being fastened to bolts extending up from the top or out from the side of the wall, or by interfitting into recesses made in the top of the wall.Type: ApplicationFiled: December 31, 2000Publication date: March 14, 2002Inventor: Eric Webb

Publication number: 20010037614Abstract: An overhanging form system for attachment to a support structure is disclosed. The support structure includes an upper portion and a lower portion, and the overhanging form system comprises a pair of spaced apart hangers, with each of the hangers being adapted to engage the upper portion of the support structure. A pair of frames are provided, with each of the frames having a first portion and a second portion. The first portion of each frame engages a corresponding one of the hangers, the second portion of each frame is adapted to engage the lower portion of the support structure. Each of the frames further includes a first leg and a second leg, with the first leg having an inner end disposed adjacent the first portion of the frame and an outer end disposed outwardly from the first portion of the frame. The second leg extends from the second portion of the frame to engage the outer end of the first leg. A plurality of stiffeners are provided.Type: ApplicationFiled: February 15, 2001Publication date: November 8, 2001Inventor: John J. Hambelton

Patent number: 6298612Abstract: A wall strengthening component for a building construction, the building construction having a plurality of spaced apart vertical studs within a frame of a building wall or the like, the wall strengthening component includes first and second vertical support members disposed in a spaced apart relationship and a plurality of reinforcing members disposed between the first and second vertical support members. The reinforcing members are configured to resist lateral stress directed against the vertical support members such that the position of the first vertical support member is maintained relative to the position of the second vertical support member. The reinforcing members are configured in a truss-like arrangement forming triangular shaped portions between the vertical support members.Type: GrantFiled: January 29, 1996Date of Patent: October 9, 2001Inventor: James A.
