球型网架结构具有强度高、韧性好、整体刚性好、制作方便、施工速度快、建设周期短等一系列优点,其在建筑工程中应用越来越广泛。因而,对大跨度球型网架结构高空拼装及吊装的施工技术进行分析,不断完善屋盖球形网架结构高空拼装及分片吊装关键技术,意义重大。 Ball grid structure with a high strength, good toughness, the overall rigidity, easy production, construction speed, short construction period and a series of advantages, its application in construction more widely. Therefore, it is of great significance to analyze the construction techniques of the assembly and hoisting of the large-span spherical grid structure at high altitudes and to continuously improve the key technologies of the dome-shaped grid structure roof assembly and hoisting.
