20080245004 | AUTOMATIC TAKE-UP DEVICE AND IN-LINE COUPLER - A tension connection for a building includes a first elongated tension member having proximal and distal ends, the first elongated tension member being anchored at its distal end, a second elongated tension member having proximal and distal ends, the second elongated tension member being anchored at its distal end, and the proximal ends of the first and second elongated tension members being disposed in close proximity and connected by a coupler, having a surrounding sleeve, the coupler being formed with a connection end and a take-up end, and a central bore wherein at least a portion of the central bore is formed as a substantially cylindrical inner surface and wherein at least a portion of the cylindrical inner surface is formed with a thread, the coupler also being formed with a first rotational member, having a distal end and a proximal end, the rotational member being received in the central bore of the surrounding sleeve and operatively connected to the surrounding sleeve, the first rotational member having a cylindrical outer surface formed with a thread that mates with the thread of the cylindrical inner surface of the surrounding sleeve and is connected to the surrounding sleeve only by the mating attachment of the thread on the cylindrical outer surface with the thread of the surrounding sleeve, such that the rotational member can rotate in relation to the surrounding sleeve, and a torsion spring connects the first rotational member and the surrounding sleeve, the torsion spring biasing the first rotational member and the surrounding sleeve in opposite rotational directions such that the first rotational member can be drawn into the surrounding sleeve. | 10-09-2008 |
20090173019 | ROTATING CONCENTRIC HOLDOWN - A connection between a wall stud or post and an anchor bolt embedded in a concrete foundation, using a holdown connector that attaches to the anchor bolt and supports the wall stud or post above it. The holdown connector has a tapered bottom that allows it to rotate laterally, allowing the connection to act more purely in tension than is possible with a rigid connection. | 07-09-2009 |
20110179725 | 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 blocks, one each affixed to a top and bottom flange of a beam. Each buckling restraint block includes one or more bores formed through a center of the block. The lateral bracing system further includes at least one yield link for each buckling restraint block. Each yield link includes a first end affixed to the column, and a second end fit through a bore in a buckling restraint block and affixed to an end of the buckling restraint block. | 07-28-2011 |
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 |
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 |
20140311059 | 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. | 10-23-2014 |
20150159362 | 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. | 06-11-2015 |
20150184413 | Self-Centering Braced Frame for Seismic Resistance in Buildings - An elongated tension-only or centering brace for a structural frame is provided where the brace is anchored at a first attachment point and to a second attachment point that is removed from the first attachment point. The elongated tension-only brace has one or more elastic restoring force elements that have effective lengths greater than the length of the tension only brace between the attachment points. | 07-02-2015 |
