1. A concrete reinforcing bar support comprising:
- a base;
a support structure extending upwardly from said base, said support structure having a channel formed in an upper surface thereof, said channel extending in a direction and having a size suitable for receiving a first rebar therein;
a first clamping structure fixed to said support structure on one side of said channel, said first clamping structure having a interior surface suitable for receiving a second rebar therein extending in a direction transverse to the first rebar; and
a second clamping structure affixed to said support structure on an opposite side of said channel, said second clamping structure having an interior surface suitable for receiving the second rebar therein, said second clamping structure being in spaced parallel relationship to said first clamping structure, each of said first and second clamping structures comprising;
a generally U-shaped member extending flexibly upwardly from said support structure;
a first arm affixed to an upper end of one side of said U-shaped member; and
a second arm affixed to an upper end of an opposite side of said U-shaped member, said first arm having a lever portion extending upwardly beyond said upper end of said U-shaped member, said second arm having a lever portion extending upwardly beyond said upper end of said U-shaped member, said first arm having a retaining portion extending into an interior of said U-shaped member, said second arm having a retaining portion extending into an interior of said U-shaped member and facing said first arm, said retaining portion of said first arm facing said retaining portion of said second arm, the retaining portion of said first and second arms having a generally zig-zag cross-section.
