Abstract

A re-bar clamp assembly for use in forming concrete footings that require the reinforcing steel rods to be spaced upwardly at a predetermined height above the ground so that when the concrete is poured into the footings the reinforcing bars will be completely encapsulated by the concrete. One of the forms of the re-bar clamp assembly is formed of a pair of first and second C-shaped clamps that are attached to each other in a stacked vertical orientation but with the open mouth of each clamp oriented substantially 90 degrees away from each other. Thus when the re-bars are snapped into the clamp assembly they will be oriented at 90 degrees to each other. A second form of the re-bar clamp assembly has a horizontally oriented C-shaped clamp that forms a slot for detachably curved finger extending re-bar steel rod. A resilient spring finger on the C-shaped clamp extends inwardly above the stake slot area and fictionally holds the clamp at any predetermined height on the stake.

Claims

1. A re-bar clamp assembly comprising:

a first C-shaped clamp having a top arcuate portion, a bottom arcuate portion, and a vertical connecting portion;

a second C-shaped clamp having a top arcuate portion, a bottom arcuate portion, and a vertical connecting portion; and

means connecting the bottom arcuate portion of said first C-shaped clamp to the top arcuate portion of said second C-shaped clamp so that the open mouth of each of said clamps is oriented substantially 90 degrees away from each other.

2. A re-bar clamp assemby as recited in claim 1 wherein said first and second C-shaped clamps are made of plastic material and they are integrally formed as a single member.

3. A re-bar clamp assembly as recited in claim 1 wherein said means connecting the bottom arcuate portion of said first C-shaped clamp to the arcuate portion of said second C-shaped clamp is a swivel which allows said open mouths to swivel toward and away from each other.

4. A re-bar assembly as recited in claim 1 wherein said means connecting the bottom arcuate portion of said first C-shaped clamp to the top arcuate portion of said second C-shaped clamp fixedly connects said clamps together.

5. A re-bar assembly as recited in claim 1 additionally comprising a third C-shaped clamp having a top arcuate portion, a bottom portion, a vertical portion, and an open mouth and connection means for connecting the bottom portion of said third C-shaped clamp to the vertical portion of one of said first and second C-shaped clamps.

6. A re-bar assembly as recited in claim 5 wherein said connecting means fixedly positions said third C-shaped clamp to the connected one of said second and third C-shaped clamps.

7. A re-bar assembly as recited in claim 5 wherein said connecting means rotatably positions said third C-shaped clamp and the to one of said first and second C-shaped clamps.

8. A re-bar assembly as recited in claim 5 wherein said open mouth of said third C-shaped clamp is orientated 90 degrees from the open mouths of said first and second C-shaped clamps.
