索结构冷却塔是一种非常规的冷却塔结构形式,该类结构由塔身索网、加劲钢环梁及塔内的钢桅杆组成,冷却塔围护可采用膜材或其他覆盖材料。根据塔身索网的不同布置方式,提出了4种不同形式的索结构冷却塔,并对一个算例进行了分析以得到索结构冷却塔的静力性能。在此基础上与同几何尺寸的钢结构冷却塔进行了经济性对比。分析结果表明,索结构冷却塔受力明确合理,具有一定的经济可行性和环保高效的施工过程,极具研究价值和应用前景。
The cable structure cooling tower is an unconventional cooling tower structure. The structure is composed of tower cable nets, stiffened steel ring beams and steel trusses in the tower. The cooling tower enclosure can be made of membrane material or other covering materials. According to different layouts of tower cable nets, four different types of cable-structured cooling towers are proposed, and an example is analyzed to obtain the static performance of cable-structured cooling towers. On this basis, economical comparisons were made with steel cooling towers of the same geometry. The analysis results show that the cable structure cooling tower is clear and reasonable stress, has a certain economic feasibility and environmental protection and efficient construction process, with great research value and application prospects.
