Now there are very good connection methods! The utility model relates to a new steel bar integral butt joint technology, which is suitable for the integral butt joint of steel bar cages. The integral butt joint of 32 steel bars can be completed within half an hour. Similarly, the reinforced continuous wall (ground connected wall), the whole butt joint of the reinforced inverted arch mesh in the tunnel and the connection of the rigid column of the steel structure can effectively replace the connecting wing plate in the steel structure and improve the field efficiency. The new reinforced sleeve can be connected without rotating the reinforcement!
