20130031868 | CORRUGATED SHEARWALL - A prefabricated shearwall including a central diaphragm having a height generally defined by top and bottom edges, and a width generally defined by a pair of end sections. The diaphragm further includes at least one corrugation extending in the height direction at least partially between the top and bottom edges. The corrugation increases the ductility and ability of the shearwall to withstand lateral forces such as those generated in earthquakes, high winds, floods and snow loads. | 02-07-2013 |
20110308190 | MOMENT FRAME CONNECTOR - A lateral bracing system is disclosed for affixing a column to a beam in a construction. The lateral bracing system includes a pair of buckling restraint plates, one each affixed to a top and bottom flange of a beam. The lateral bracing system further includes at least one yield plate for each buckling restraint plate. Each yield plate includes a first end affixed to the column, and a second end affixed to the beam. | 12-22-2011 |
20110296787 | MOMENT FRAME LINKS WALL - A lateral bracing system having high initial stiffness and including yield links capable of effectively dissipating stresses generated within the lateral bracing system under lateral loads. | 12-08-2011 |
20110197544 | CORRUGATED SHEARWALL - A prefabricated shearwall including a central diaphragm having a height generally defined by top and bottom edges, and a width generally defined by a pair of end sections. The diaphragm further includes at least one corrugation extending in the height direction at least partially between the top and bottom edges. The corrugation increases the ductility and ability of the shearwall to withstand lateral forces such as those generated in earthquakes, high winds, floods and snow loads. | 08-18-2011 |
20100275540 | Corrugated Shearwall - A prefabricated shearwall including a central diaphragm having a height generally defined by top and bottom edges, and a width generally defined by a pair of end sections. The diaphragm further includes at least one corrugation extending in the height direction at least partially between the top and bottom edges. The corrugation increases the ductility and ability of the shearwall to withstand lateral forces such as those generated in earthquakes, high winds, floods and snow loads. | 11-04-2010 |
20100239387 | TAKE-UP FASTENER FOR RESISTING UPLIFT LOADS IN LIGHT FRAMED CONSTRUCTION - A take-up fastener is disclosed for fastening a level in a frame construction to the level below so as to resist upward forces generated by wind and other sources on the framed construction. The take-up fastener in general includes a take-up plate, or washer, fastened to a portion of the upper level and a take-up screw fit through the take-up plate and fastened to the adjacent level below. Once the take-up fastener is fully assembled, the take-up plate includes a pair of tabs which are capable of engaging threads on a take-up screw in a way that allows one-way motion of the take-up screw relative to the take-up plate. In particular, the take-up plate can move downward relative to the take-up screw, for example on constricting of the wooden members to which the take-up plate is affixed. However, the engagement between the take-up plate and take-up screw prevents movement of the take-up plate upward with respect to the take-up screw, for example upon an upward load due to wind or other external force. | 09-23-2010 |
20100107545 | Construction Frame Shear Lug - A shear lug is disclosed for transferring shear stresses from a structural element, such as a column in a framing element, down into the foundation supporting the framing element. The shear lug is not initially affixed to the structural element. The shear lug is instead affixed to anchor rods of an anchorage assembly, and is installed into the foundation with the anchorage assembly at the time the concrete foundation is poured. The structural element is subsequently affixed to the anchor rods, so that shear forces are transferred from the structural element, through the anchor rods and to the shear lugs, which effectively dissipate the shear forces to the foundation. | 05-06-2010 |
20100018151 | PORTAL FRAME - A portal frame is disclosed for use around portals in, for example, a light-framed construction. The portal frame includes a pair of vertically-oriented shearwalls, and a header extending between and connected to the shearwalls. The portal frame may be used around a variety of portals formed in a construction, including for example doors, garage doors and windows. By forming a portal frame using a pair of shearwalls connected to a header, the portal frame in embodiments of the present invention is able to effectively reduce the loads exerted on a foundation by the shearwalls in comparison to a shearwall acting alone (i.e., one that is not part of a portal frame). | 01-28-2010 |
20090196694 | CONSTRUCTION CONNECTOR ANCHOR CAGE SYSTEM - An anchor member securing system includes a securing member and a rebar cage structure secured to the member. The securing system may include at least a first foundation placement guide. The anchor members may comprise mudsill anchors and anchor bolts, and the system provides more exact placement of the member or members in a foundation. | 08-06-2009 |
20090142160 | RAISED RECESS TRUSS HEAD SCREW - A truss screw is disclosed for use in fastening framing members together. In embodiments, the truss screw includes a raised recess section having walls extending from a top surface of the screw head. The raised recess sinks into the back surface of a workpiece fastened to the framing members so that the workpiece may sit flat against the workpiece. | 06-04-2009 |
