Abstract
A remotely installable piping support attachment assembly employs a T-bolt type fastener for clamping a relatively smaller instrumentation pipe, e.g., the jet pump sensing line, to the wall of an adjacent structure. The attachment assembly includes a T-bolt, a split pipe clamp support, a ratchet nut with peripheral ratchet teeth, and a ratchet lock washer. When the nut is tightened on the threaded shank of the T-bolt, a top plate and an anchor of the split pipe clamp support are pressed together to clamp the jet pump sensing line therebetween. The top plate is defined by an L-beam folded spring plate comprised of first and second plate parts disposed generally in parallel and joined at a living hinge flex joint so that said plate parts each have a free end edge remote from said flex joint, the free end edges being spaced apart to define a gap therebetween without preload.
