青岛世界园艺博览会植物馆钢结构施工技术

Construction of the Steel Structures of Plant Museum in World Gardening Exhibition Qingdao

结合青岛世界园艺博览会植物馆钢结构工程特点——桁架、网壳等跨度大、面积大,整体运输易产生变形且费用高,采用工厂杆件加工、现场拼装、分段吊装组装的施工工艺。重点介绍了管桁架、单层网壳等钢结构加工、拼装、焊接、分段分片吊装等施工技术。指出钢结构全部焊接完成后,各单体循环等比卸载。

Combined with the steel structure features of plant museum of the World Gardening Exhibition Qingdao, such as the truss and shells have large span and areas, it is easy to deform for integral transportation, the construction techniques of components processing in factory, assembly on site, and segmental hoisting and assembly are applied. The construction of the steel structures processing, assembling, welding and segmental hoisting of tube truss and single-layer shell are introduced in detail, it is pointed out that after welding of the steel structures, each unit uses cycle proportional unloading.
