Abstract

A concrete reinforcing bar support including a base, a support structure extending upwardly from the base, a first clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, a second clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, and a third clamping member affixed to the support structure and extending upwardly above the top surface of the support structure. The second clamping member has an interior surface generally facing the interior surfaces of the first and third clamping members. The first clamping member is separated by a space from the third clamping member. Ribs extend inwardly from the interior surfaces of each of the clamping members so as to compressively contact a reinforcing bar placed interior of the clamping members. The support structure has a generally H-shaped cross-section in a plane parallel to said base.

Claims

1. A concrete reinforcing bar support comprising:

a base;

a support structure extending upwardly from said base, said support structure having a top surface;

a first clamping member affixed to said support structure and extending upwardly above said top surface, said first clamping member having an interior surface; and

a second clamping member affixed to said support structure and extending upwardly above said top surface, said second clamping member having an interior surface generally facing said interior surface of said first clamping member, said interior surface of said first and second clamping members being suitable for receiving a reinforcing bar therebetween, said base and said support structure and said first and second clamping members being integrally formed together of a polymeric material, each of said first and second clamping members having a plurality of ribs extending inwardly from said interior surface.

2. The bar support of claim 1, further comprising:

a third clamping member affixed to said support structure and extending upwardly above said top surface, said third clamping member having an interior surface generally facing said interior surface of said second clamping member, said third clamping member being separated by a space from said first clamping member, said third clamping member having a plurality of ribs extending inwardly from said interior surface.

3. The bar support of claim 2, said second clamping member positioned in a plane of said space between said first and third clamping members.

4. The bar support of claim 3, each of said first clamping member, second clamping member and said third clamping member having a detent formed thereon, said detent having an angled surface extending upwardly and outwardly therefrom.

5. The bar support of claim 1, each of said plurality of ribs being parallel to and spaced from an adjacent rib.

6. The bar support of claim 1, a lower rib of said plurality of ribs extending inwardly from said interior surface a greater distance than a distance that an upper rib of said plurality of ribs extends inwardly form said interior surface.

7. The bar support of claim 1, each of said plurality of ribs being flexible.

8. The bar support of claim 1, each of said plurality of ribs extending in a horizontal plane.

9. The bar support of claim 1, said first and second clamping members having an identical configuration facing in opposite directions.

10. The bar support of claim 1, each of said first and second clamping members being resilient members, an innermost edge of said interior surface of said first clamping member being spaced from an innermost edge of said interior of said surface of said second clamping member by less than a diameter of the reinforcing bar.

11. The bar support of claim 1, said base being a flat surface, said support structure comprising:

a first truncated pyramidal wall extending upwardly and inwardly from one side of said base;

a second truncated pyramidal wall extending upwardly and inwardly from another side of said base; and

a panel extending upwardly from said base between said first and second truncated pyramidal walls.

12. The bar support of claim 11, said panel having a plurality of holes formed therein so as to allow a free flow of concrete therethrough.

14. The apparatus of claim 13, said second clamping member having an identical configuration of each of said first and third clamping members, said second clamping member facing in a direction opposite to that of said first and third clamping members.

15. The apparatus of claim 13, said support structure having a generally H-shaped cross-section in a plane parallel to said base.

16. The apparatus of claim 13, said panel having a plurality of holes formed therein so as to allow a free flow of concrete therethrough.

17. The apparatus of claim 13, each of said clamping members having a plurality of ribs extending inwardly from the respective interior surfaces thereof, each of said plurality of ribs contacting an exterior surface of said reinforcing bar.

18. The apparatus of claim 17, a lower rib of said plurality of ribs extending inwardly of said interior surface a greater distance than an upper rib of said plurality of ribs extends inwardly from said interior surface, each of said plurality of ribs being flexible.

19. The apparatus of claim 13, said base and said support structure and said clamping members being integrally formed together of a polymeric material.

13. An apparatus comprising:

a reinforcing bar having a length dimension and a diameter dimension;

a base;

a support structure extending upwardly from said base, said support structure comprising;

a first truncated pyramidal wall extending upwardly and inwardly from one side of said base;

a second truncated pyramidal wall extending upwardly and inwardly from another side of said base; and

a panel extending upwardly from said base between said first and second truncated pyramidal wall;

a first clamping member affixed to said support structure and extending upwardly above said top surface, said first clamping member having an interior surface;

a second clamping member affixed to said support structure and extending upwardly above said top surface, said second clamping member having an interior surface generally facing said interior surface of said first clamping member; and

a third clamping member affixed to said support structure and extending upwardly above said top surface, said third clamping member having an interior surface generally facing said interior surface of said second clamping member, said second clamping member positioned between said first clamping member and said third clamping member along said length dimension of said reinforcing bar, said first and third clamping members resiliently compressively contacting one side of said reinforcing bar, said second clamping member resiliently compressively contacting another side of said reinforcing bar.

20. A concrete reinforcing bar support comprising:

a base;

a support structure extending upwardly from said base, said support structure having a top surface;

a first clamping member affixed to said support structure and extending upwardly above said top surface, said first clamping member having an interior surface;

a second clamping member affixed to said support structure and extending upwardly above said top surface, said second clamping member having an interior surface generally facing said interior surface of said first clamping member; and

a third clamping member affixed to said support structure and extending upwardly above said top surface, said third clamping member having an interior surface generally facing said interior surface of said second clamping member, said third clamping member being separated by a space from said first clamping member, each of said first clamping member and said second clamping member and said third clamping member having a plurality of ribs extending inwardly from the respective interior surfaces thereof, each of said plurality of ribs being parallel to and spaced from an adjacent rib.
