ABSTRACT:
A segmented retainer gland assembly for holding pipe joints and the like together, including at least two gland segments in the shape of a circular arc forming together a circular gland for securing around a circular pipe, each of the segments having end flanges projecting substantially perpendicular to one side face of the gland segment, a clamping bracket having an inside face provided with a recess sized and shaped to receive the two end segment end flanges when adjacent ends of the gland segments are positioned together, each of the clamping brackets and gland segments having bolt holes and each of the clamping brackets having corresponding bolt holes which align with the bolt holes in the gland segments when the segments are positioned together, and bolts and nuts for securing the clamping brackets on the gland segments to hold the segments together at the end flanges to form a circular gland when the flanges are assembled together. Tapered, circular, and square configured gland segment end flanges and clamping bracket inside recesses are provided in different embodiments. A joint restraint harness is also disclosed including two gland assemblies, one on a pipe spigot end and the other on a bell of a joint, held together by axial tie rods.
