Double production line for segmental beam prefabrication
A recently granted patent (Publication Number: US11969915B2) discloses a double production line for segmental beams, consisting of two production machines and a track system on a construction ground. Each production machine includes fixed end molds, side molds, bottom mold trolleys, middle internal mold trolleys, and side internal mold trolleys. The track system features transverse and longitudinal tracks, with pouring positions aligned along the transverse track and the longitudinal track positioned between them. The molds and trolleys work together to define pouring cavities, with specialized components like side formwork and internal mold assemblies contributing to the production process.
Furthermore, the patent details the design of the middle internal mold trolley, which includes movable and fixed internal mold assemblies to create reinforcing ribs in the segmental beams. The middle movable internal mold assembly comprises various components like inner plates, formworks, and driving mechanisms to facilitate the molding process. Additionally, features such as pulley assemblies, recesses on the construction ground with lifting platforms, and docking mechanisms for the track systems enhance the efficiency and functionality of the double production line for segmental beams. Overall, the patent highlights a comprehensive system for producing segmental beams with precision and structural integrity.
