Abstract
A cage assembly for spacing inner and outer concrete pipe reinforcing welded wire cages from one another through the use of a spacer bar. The spacer bar includes a plurality of links, each having a hook-shaped deviation therein, joined by a tie rod. The links are inserted through one of two cages until the tie rod abuts the cage and the hook deviations are then hooked over a longitudinal or circumferential wire or both in the other cage. Each link also includes at least one form spacer projection projecting from one end thereof in order to space the entire inner and outer cage assembly from the inner and/or outer wall of a pipe form.
