Abstract

A concrete reinforcing bar support has a base, a support structure extending upwardly from the base and a having a channel formed in an upper surface thereof, a first clamping structure affixed to the support structure on one side of the channel and second clamping structure affixed to the support structure on an opposite side of the channel. Each of the first and second clamping structures includes a first C-shaped member and a second C-shaped member extending flexibly upwardly from the support structure and facing in opposite directions. A cap is slidably affixed over these C-shaped members and the channel.

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 affixed to said support structure on one side of said channel, said first clamping structure having an interior surface suitable for receiving a second rebar therein extending in a direction transverse to the first rebar;

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 relationship to said first clamping structure, each of said first and second clamping structures comprising;

a first C-member extending flexibly upwardly from said support structure; and

a second C-shaped member extending flexibly upwardly from said support structure, said first and second C-shaped members facing in opposite directions, each of said first and second C-shaped members having a flange element extending angularly upwardly and outwardly therefrom; and

a cap having a first slot and second slot extending longitudinally along opposite sides thereof, said first slot slidably engaging the flange elements of the first C-shaped member of said first and said second clamping structures and said second slot slidably engaging the flange elements of the second C-shaped member of said first and said second clamping structures.

2. The bar support of claim 1, said first C-shaped member of said first and second clamping structures located between said second C-shaped member and a respective side of said channel.

3. The bar support of claim 2, said first C-shaped member of said first and second clamping structures facing in the same direction, said second C-shaped member of said first and second clamping structures facing in the same direction.

4. The bar support of claim 1, said support structure having a first reinforcing rib extending vertically upwardly therealong from said base to said first C-shaped member of said first and second clamping structures, said first reinforcing rib extending along a back of said first C-shaped member of said first and second clamping structures.

5. The bar support of claim 4, said support structure having a second reinforcing rib extending vertically upwardly therealong from said base to said second C-shaped member of said first and second clamping structures, said reinforcing rib extending along a back of said second C-shaped member of said first and second clamping structures.

6. The bar support of claim 1, each of said pair of slots being open at one end thereof and closed at an opposite end thereof.

7. The bar support of claim 1, said cap having a curved surface extending between said pair of slots, said curved surface having a shape generally conforming to an outer surface of a rebar extending through said first and second clamping structures.

8. The bar support of claim 1, said channel comprising:

a generally semi-cylindrical channel extending outwardly of a first side and a second side of said support structure;

a first gusset extending between a bottom of channel and said first side of support structure; and

a second gusset extending between a bottom of said channel in said second side of said support structure.

9. 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;

a first clamping structure affixed to said support structure on one side of said channel;

a second clamping structure affixed to said support structure on an opposite side of said channel, said second clamping structure being in spaced relationship to said first clamping structure;

a first rebar extending through said channel;

a second rebar extending in a direction transverse to said first rebar, said second rebar extending through said first and second clamping structures; and

a cap affixed on said first and second clamping structures and over said first and second rebars, each of said first and second clamping structures comprising;

a first C-shaped member extending flexibly upwardly from said support structure; and

a second C-shaped member extending flexibly upwardly from said support structure, said first and second C-shaped members facing in opposite directions to each other, each of said first and second C-shaped members having a flange element extending angularly upwardly and outwardly therefrom,

said cap having a first slot and second slot extending longitudinally along opposite sides thereof, said first slot slidably engaging the flange elements of the first C-shaped member of said first and said second clamping structures and said second slot slidably engaging the flange elements of the second C-shaped member of said first and said second clamping structures, each of said slots being open at one end thereof and closed at an opposite end thereof.

10. The bar support of claim 9, said cap slidably engaged with said first and second clamping structures.

11. The bar support of claim 9, said cap having a curved surface generally conforming to an outer surface of said second rebar.
