  • 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 prestrcssed 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 T-beams 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.
  • PATENTED DEC 18 975 l CONCRETE COOLING TOWER BACKGROUND OF THE INVENTION This invention relates generally to the construction of cooling towers, and more particularly to the construction of an improved concrete cooling tower shell design made from a minimum number of precast factory-made parts which can be trucked to the jobsite.
  • cooling towers instead of wood are apparent, primarily due to the increased life of the structure since the concrete structure will not deteriorate as does wood by rotting. Further, the need for expensive sprinkler systems is eliminatedand insurance premiums cost less. While cooling towers have heretofore been made of prefabricated concrete parts, these towers have not been able to economically compete with the conventional wooden towers. The heretofore known concrete tower designs have either utilized numerous small light weight precast building elements, facilitating handling but requiring many time consuming steps to erect, or have utilized large cast-in-place elements which have significantly increased the cost of the tower.
  • the present invention discloses a cooling tower constructed entirely of concrete, metal and plastic parts that is economically competitive with conventional wooden towers. This is accomplished by fabricating the tower from a minimum number of uniquely designed precast prestressed wall panels, T beams and louver posts. These structural elements although relatively large in size, may be readily prefabricated and do not require a large amount-of field work during errection because of the unique interrelationship between the elements.
  • Another object is to provide a concrete cooling tower which utilizes a minimum number of factory-made concrete parts which can be trucked to the jobsite.
  • a further object is to provide a concrete cooling tower which utilizes a minimumnumber of interrelated precast concrete elements which are specially designed to reduce field erection time.
  • Still another object is to provide a concrete cooling tower which utilizes a self-supporting structurev that does not require internal structural support and therefore results in improved thermal performance.
  • a still further object is to provide a unique simplified method of constructing such a concrete cooling tower in a manner which minimizes field erection time.
  • Another object of the invention is to provide a concrete tower which utilizes factory-made parts that can be put together in different combinations to form various multi-cell cooling towers.
  • the present invention provides a concrete cooling tower, the shell of which is fabricated from three basic precast prestressed building elements; namely: wall panels, T-beams and louver posts.
  • the wall panels are precast to the necessary length to permit them to be tilted up into position above a foundation in a simple one step operation.
  • the louver posts are precast and tilted up into position above the foundation.
  • the louver posts containlouver blade receiving slots cast therein and an aerodynamic nose to reduce the pressure drop across the louver blade assembly.
  • the T-beams are positioned above the louver posts and wall panels to form the top deck of the tower.
  • the T-beams 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 further includes curb portions to define a hot water distribution basin thereabove.
  • the tower filling is supported from the T-beams rendering unnecessary any internal structural support for the tower or fill that would retard the movement of air and interfere with thermal performance.
