| 摘 要： | 苏州火车站钢屋盖为198 m大跨度钢结构,受施工条件限制,为满足工期需要,在二层楼面结构未完成前同时施工、安装大体量钢构件,为避免相互干扰太大,采用＂单榀钢桁架就地拼装,分段吊装,高空组装后累积滑移＂的安装施工工艺。安装实践表明,该种施工工艺适用于周边条件受限的大跨度钢结构的快速施工。

| Abstract: | Steel roofs of Suzhou Railway Station have a 198 m big-span steel structure.Limited by the construction conditions and to meet the construction period requirements,the bulk mass steel members are constructed and installed before the accomplishment of the second floor structure.To avoid big mutual interference,an installation construction technique is adopted,that is,single-roof-truss steel trusses are assembled on site,and hoisted by segments,and accumulated slips after high-air assembling.Installation prac... |
