Abstract
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.
Claims16
A three-dimensional jacket-plate connector to connect at least two I-beam members, each member comprising a steel I-beam section, the jacket-plate connector comprising
- a first three-dimensional jacket plate;
- and
- a second three-dimension jacket plate that is a mirror image of the first three-dimensional jacket plate, the two jacket plates bolted to opposite sides of a joint connecting a continuous primary I-beam member and one or more connected secondary I-beam members,
- wherein a jacket plate comprises one or more branching secondary C-channels connected to a continuous primary C-channel that intersect to match angles of the joint formed between a longitudinal axis of the one or more connected secondary I-beam members and a longitudinal axis of the continuous primary I-beam member,
- at least one threaded tension rod installed through the depth of the cross section of the primary C-channel of the jacket plate to transfer bending moments and shear forces across the joint, and
- at least one steel plate stiffener welded between the flange portions of the primary I-beam member to counteract the compression forces caused by the at least one threaded tension rod.
3 more elements
The connector of 1, wherein a box space surrounded by opposing flanges of the connected I-beam member in the vertical direction;
- and by a side plate of a jacket plate and the web of connected secondary I-beam member in the horizontal direction, allow access from an open end for tightening of nuts of bolts.
