ABSTRACT:
A prestress wire splicing apparatus is used to replace sections of wire used in prestressing concrete pipe, where a section of wire has either failed due to corrosion or has been removed for inspection purposes, and to restore the proper amount of tension necessary to keep the concrete pipe in a net overall compression force. The prestress wire splicing apparatus comprises a set of anchor blocks for attachment to the ends of wires, a stop screw for holding a set of the anchor blocks apart, a clamp bolt for securing a set of the blocks together, and a hydraulic clamping device for pressing a set of blocks toward each other. A splice-wire anchor block is attached to each end of a splice wire. An exposed-wire anchor block is attached to each remaining wire end. A clamping device is attached and operated to compress the anchor blocks together to a desired tension force. A clamp bolt is tightened to maintain the tension and the clamping device is removed. Each anchor block has a longitudinal groove with a plurality of teeth spaced apart along its length for engaging a wire with the wire surface flush with the surface of the block.
