摘要
北京绿地中心工程钢结构雨篷采用大悬挑无拉结做法,钢结构受力复杂,钢结构预埋钢骨梁与钢筋交叉部位较多,钢构件等施工难度大。雨篷下部支撑采取半悬挑脚手架支撑体系。钢结构雨篷支撑体系卸荷后,对雨篷进行变形观测,均满足设计及规范要求。
Beijing Greenland Center project adopts large cantilever cable-free steel structure canopy, which bears complex forces and has dense cross between pre-embedded steel beam and steel bars. There are great difficulties in construction of steel members. The lower part of the canopy is innovatively supported by using semi-cantilever scaffold supporting system. After the supporting system is removed, canopy deformation successfully satisfies design requirements and specifications.
