Joint for Rapid Structural Assembly

Quickly attaching joint used in variety of truss structures. Split ring made in one piece and split radially after final machining. Mating tapers on split ring and endbells small: approximately 7 degrees. Tapers of this range permit high internal preloads to be obtained, yet parts easily separated when collar released. Results from tests on developmental model indicate load-displacement response linear and substantial preloading accomplished. Quickly-erecting truss structures have variety of applications, from Earth to space-station keel beams, antenna masts, and large platforms.
