鄂尔多斯东胜区植物园温室屋盖结构采用大跨度空间结构,其屋盖曲面为有中心筒支撑的自由曲面。针对温室结构特点,在研究了国内外典型温室结构的基础上,对适用本项目的结构形式进行了研究。对单层、双层结构体系受力性能进行了对比,并结合建筑造型采用了单层空间结构体系;由于施工难度较大,针对钢结构、铝合金结构分别进行了结构受力性能、节点构造、施工难度、施工速度以及建造与使用成本等方面的对比研究,最终选用了铝合金结构;对ETFE气枕结构与玻璃屋面进行了技术经济性对比,最终确定采用玻璃屋面。最后对屋盖结构的设计情况进行了介绍。
Dongsheng Botanical Garden in Ordos, Greenhouse roof structure using long-span space structure, the roof surface is a free-form center tube support surface. In view of the characteristics of the greenhouse structure, the structure of the greenhouse structure suitable for this project has been studied on the basis of studying the typical greenhouse structures at home and abroad. The mechanical performance of single-story and double-story system is compared with that of single-story space structure system. Because of the difficulty of construction, the mechanical behavior of steel structure and aluminum alloy structure are respectively studied. , Construction difficulty, construction speed and cost of construction and use of the comparative study of the final selection of the aluminum alloy structure; ETFE pillow structure and glass roof of the technical and economic comparison, and ultimately determine the use of glass roof. Finally, the design of the roof structure is introduced.
