航空航天试验场的使用功能要求建造一个全封闭、直径50m的圆形或边长50m的方形的建筑空间,中间无柱、净空高40m、门口尺寸不小于22m宽、20m高;且方便拆卸、运输和安装,要求从秦皇岛拆除然后到新疆安装完毕的周期为20d,其中包括4d的长途运输时间。如果采用常规轻钢结构建造如此庞大的空间结构,且由于秦皇岛海滩和新疆戈壁滩地基处理复杂,其拆卸、运输和安装周期根本无法满足要求。采用组合式充气膜结
The use of aerospace test site requires the construction of a fully enclosed, 50m diameter circular or rectangular side of the building space 50m, the middle column, headroom 40m, the door size of not less than 22m wide and 20m high; and easy removal, Transportation and installation, requiring removal from Qinhuangdao and then to Xinjiang to complete the installation period of 20d, including the 4d long-distance transport time. If such a large space structure is constructed by the conventional light steel structure and the handling of Qinhuangdao Beach and the Gobi Desert foundation in Xinjiang is complex, the period of disassembly, transportation and installation simply can not meet the requirements.
