Abstract
A method and apparatus for rebar cage construction is disclosed. A computerized controller operates an apparatus that automates parts of the rebar cage formation process. The computer controls motors for rotating the barrel and operating a wagon containing spiral coil wire. Initial rods are placed on a plurality of latitudinal conveyors. Dual cage ring assemblies are placed on the latitudinal conveyors, and notches or slots within the cage rings engage with the initial rods. The conveyors rotate the dual cage ring assemblies and a rod dispenser places a rod in additional notches. The rods, when completely installed, form a barrel structure. A wagon containing spiral coil wire is then moved longitudinally while the conveyors rotate to wrap the spiral coil wire around the barrel, to form a spiraled rebar cage.
