                                  [摘要]大跨度鋼網架結構是運用較多的大跨度空間結構形式,在機場、車站、體育場館、會議會展中心運用較為廣泛。鋼網架結構的發展,促進了施工方法的不斷提高。施工方法的選擇則受施工場地條件、施工難易程度、工期及成本的制約,需進行方案必選,以選擇最優施工方案。成都天府國際機場航站樓鋼結構工程施工一標段DC預留區網架,由于現場施工場地狹窄、工期要求緊迫,故選擇采用無支撐分塊吊裝技術進行網架安裝施工,使得在現場施工空間狹窄的情況下,在規定時間節點內安全、順利完成3塊共計約650m2網架安裝施工任務,同時達到了節省支撐措施、節省施工工期的目的。

                                  Abstract: Large span steel grid structure is a kind of large span spatial structure, which is widely used in airports, railway stations, sports venues and convention and exhibition centers. The development of steel grid structure promotes the continuous improvement of construction methods. The selection of construction method is restricted by the conditions of construction site, the degree of construction difficulty, time limit and cost, so it is necessary to select the best construction plan. In steel structure construction of Chengdu Tianfu International Airport terminal building, the DC reserve area in bid a grid, unbraced block hoisting technology of rack installation is adopted due to the narrow construction site and a limited construction for pressing, under the condition of the narrow working space, safe and smooth finish within the prescribed time node 3 pieces, a total of about 650m2 rack installation tasks. At the same time the purpose of saving support measures and construction time is achieved.
