Novel grid cooling tower with crossed steel structure

The invention discloses a novel grid cooling tower with a crossed steel structure and relates to the grid cooling tower with the crossed steel structure, which is suitable for indirect type cooling, and belongs to the technical field of structural engineering. On the basis of a pure-steel double-curve-surface grid cooling tower, a central supporting truss flying column is additionally arranged; the central supporting truss flying column is connected with a peripheral grid shell by utilizing a pre-stress cable disc and a space inclined radiation pre-stress inhaul cable, so that a more stable space cable truss (composed of the cable disc, the fly column and the space inclined radiation pre-stress inhaul cable) and a steel grid shell crossed structure are formed. By adopting a multiple-side-force-resisting system, the side resisting rigidity and the bearing capability of the structure are remarkably improved and the utilization rate of materials is improved, so that structural design requirements of an ultra-large-size cooling tower can be met. The novel grid cooling tower adopts a steel cable and full-steel structure, and has the advantages of high production efficiency, high construction precision, short construction period, small influences caused by weather temperatures, low construction cost and the like.
