Abstract
A thrust rod anchor for utilization in conjunction with a tied form of pipe joint restrainer system. The anchor utilizes two arcuate band segments the ends of which are welded to elongate junction devices such as blocks. These junctions are bolted together in the course of assembling the anchor over the outside surface of a pipe. The assemblage of junctions and arcuate band segments support thrust rod connectors having apertures formed in thrust plates thereof advantageously spaced outwardly from the band segments. Spaced away from the thrust plates of each connector are pairs of set screws. A buttress arrangement is utilized to support the thrust plates of the tie rod connectors. The anchor assemblies have been shown to provide enhanced anchoring resistance to thrust forces and to be more facilly mounted upon a pipe surface.
