摘　　要：中国博览会会展综合体项目造型独特,尤其是其高大的空间结构,给建筑施工带来不少难题,根据以往成熟的经验,其高耸结构施工采用了大跨双向预应力梁模板作为支撑系统,具有一定的创新性。以此为例,详细介绍了支撑形式的方案比选及撑架的设计。工程中所应用的承插式盘扣形钢管支撑架,有效解决了传统支模体系在非常规结构构件施工中的难题,可为类似的工程提供参考。China Expo Complex project is special-shaped, especially its large and high space strucutre bringing difficulties to construction. According to experience, it takes a super-tall, super-heavy and two-way spanning prestressed beams template as its support system which represents a certain level of innovation in design. With this example, the paper introduced comparison of support systems and design of strut in detail. Disk lock steel tubular scaffold used in project solved difficulties of irregular structure construction, providing experience for similar projects.
