Abstract:

A rebar tying system including a chassis with a central opening that passes from top to bottom of the chassis, a plurality of driven wheels coupled to the chassis and configured to propel the rebar tying system bidirectionally over a rebar mat, a plurality of foot members coupled to the chassis and configured to selectively move the rebar tying system in a lateral direction relative the bidirectional wheel propelled movement, and a rebar tying gun configured to be selectively positionable both horizontally and vertically in the central opening to perform rebar tying operations.

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.
