Abstract: A key-locked rebar clamping assembly includes a clamp that may be forced onto the perpendicular intersection of the upper and lower rods of crossed rebar and then held from below with a key. The assembly is readily installed by forcing the clamp over the intersection of the upper and lower rods and forcing the key through a keyway in opposing sides of the clamp. The assembly holds the rods together with the clamp at the top and the key at the bottom regardless of force, vibration, and the like applied to either rod. As the key constrains downward movement of the lower rod away from the clamp and the upper rod, the lower rod will not separate from the upper rod if walked on. The assembly reduces the need to alternate longitudinal adjacent rods between upper and lower positions, thus saving labor costs through the elimination of wire tying and complicated positioning.
