Pre-stressing apparatus using a split threaded fastener |
摘要 |
<p>A fastener includes a threaded circular ring (30) half divided along a plane intersecting a central longitudinal axis. One of the end walls (42) is formed with a truncated conical load-bearing surface that is seated on a truncated conical thrust surface (58) formed on a circular ring of a stress generator. The load bearing and thrust generating surfaces are arranged to present a conjugate pair of truncated conical surfaces to provide a favorable resolution of forces developed by torque applied to jack bolts distributed about an outwardly surrounding cylindrical stress generator body section.</p> |
