Abstract

See full text

A concrete reinforcing bar support has a base, a support structure extending upwardly from the base so as to define a channel formed in an upper surface thereof, a first clamping structure affixed to the support structure on one side of the channel, a second clamping structure affixed to the support structure on the opposite side of the channel, and a rebar retainer positioned between the clamping structures for retaining the rebar in the channel. The rebar retainer includes first and second retainer members movable between a first position spaced away from each other and a second position overlying a portion of the rebar when the rebar is placed in the channel. Each of the retainer members has a generally S-shaped cross-section configuration.
