Abstract

A concrete reinforcing bar support having a base, a support structure extending upwardly from the base and having a channel formed at an upper surface thereof, a first clamping structure affixed to the support structure on one side of the channel, and a second clamping structure affixed to the support structure on an opposite side of the channel. Each of the clamping structures has a curved element extending inwardly therefrom. A first rebar extends through the channel. A second rebar is retained by the first and second clamping structures in a direction transverse to the first rebar.

Claims

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 curved element extending therein 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 a curved element extending therein 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 retainer affixed to an upper end of one side of said U-shaped member and extending inwardly and downwardly therefrom, the curved element being formed on said first retainer; and

a second retainer affixed to an upper end of an opposite side of said U-shaped member, said second retainer having a plurality of ribs extending angularly inwardly from said opposite side of said U-shaped member.

2. The bar support of claim 1, said curved element having a curvature of greater that 90°

and less than 180°

, said curved element having an end spaced from said one side of said U-shaped member.

3. The bar support of claim 1, each of plurality of ribs extending downwardly toward a bottom of said U-shaped member, each of said plurality of ribs having an end adjacent to said curved element of said first retainer.

4. The bar support of claim 1, each of said first and second clamping structures being positioned above said channel.

5. The bar support of claim 1, said base and said support structure and said first clamping structure and said second clamping structure being integrally formed together of a polymeric material.

6. The bar support of claim 1, said support structure having a plurality of holes formed therein so as to allow concrete to flow freely therethrough.

7. An apparatus comprising:

a base;

a support structure extending upwardly from said base, said support structure having a channel formed in an upper surface thereof;

a first clamping structure affixed to said support structure on one side of said channel, said first clamping structure having a first curved element extending therein;

a second clamping structure affixed to said support structure on an opposite side of said channel and arranged in generally spaced parallel relationship to said first clamping structure, said second clamping element having another curved element extending therein;

a first rebar extending in a direction and received in said channel of said support structure; and

a second rebar retained by said first and second clamping structures in a position transverse to said first rebar and above said first rebar, each of said first and second clamping structures comprising;

a generally U-shaped member extending flexibly upwardly from said support structure;

a first retainer affixed to an upper end of one side of said U-shaped member and extending inwardly and downwardly therefrom, the curved element formed on said first retainer; and

a second retainer affixed to an upper end of an opposite side of said U-shaped member, said first retainer having the curved element resiliently contacting an exterior surface of said second rebar, said second retainer having a surface resiliently contacting said exterior surface of said second rebar, said second retainer having a plurality of ribs extending angularly inwardly from said opposite side of said U-shaped member, at least one of said plurality of ribs contacting said exterior surface of said second rebar.

8. The apparatus of claim 7, said curved element having a curvature of greater than 90°

and less than 180°

, said curved element having an end spaced from said one side of said U-shaped member.

9. The apparatus of claim 7, said base and said support structure and said first clamping structure and said second clamping structure being integrally formed together of a polymeric material.
