Abstract
Abstract A concrete cooling tower shell design made from a minimum number of precast factory-made parts. The shell is fabricated from three basic precast prestressed concrete building elements; namely: wall panels, T-beams, and louver posts. The wall panels and louver posts are positioned above a foundation to define the walls of the tower. The T-beams are positioned above the louver posts and wall panels to form the top deck of the tower. The Tbeams have spray nozzle openings formed therein and have a reinforced concrete topping poured thereon in a unique manner which utilizes extension members at each nozzle opening to form a corresponding opening therethrough. The topping includes curb portions to define a hot water distribution basin thereabove.
