DESCRIPTION OF RELATED ART
Structural joint connectors have use in a variety of manufacturing and building applications to create many different products. The connectors have numerous functions that include joining panels and various different building components during production. A variety of different connectors have been developed to interconnect structural elements.
Existing devices used to secure panels and other components include the use of an extrusion with flanges designed to fit along a panel edge. Mechanical fasteners are commonly installed through the flange and into the panel in order to strengthen the joint. Other connectors that include straps, angles, edges, and end fittings with a greater thickness or different material are used to enhance the strength of joints. For example aircraft industries have created aluminum connectors to join walls, panels, and barriers for aircraft interiors.
In aerospace applications, size and weight considerations are paramount. Many existing structural components were created to decrease weight, size, or the amount of material required while providing sufficient strength to ensure an effective joint. In addition, the amount of labor hours required to assemble the components must also be considered in order to minimize manufacturing costs. Accordingly, there is a continuing need in the art for building components that are lightweight, size efficient, cost effective, and easy to assemble.
