AOP connections system included wire rope connection and bolted connection. The two ways is most used in the precast concrete connections design. Wire rope connection is casted in wire rope box into precast concrete with small out loop head. The two concrete parts loop head cast into new concrete which was mixed by high strongly slurry. The bolted connection is casted in ferrule inserts (Coil inserts) into precast concrete. The two concrete units connect together with bolt and steel plate. It was rapid and easy operating connection system in precast concrete.
