摘要
北京绿地中心4号商务办公楼工程为超高层建筑,建筑高度达260 m。在内爬塔式起重机施工过程中,对塔式起重机支撑钢梁的连接优化,通过栓焊混合连接的施工工艺,减少了内爬塔式起重机爬升作业周期,确保了塔式起重机支撑钢梁在重复动荷载环境中的连接强度,提高了工程的整体施工进度。
Beijing Greenland Center No.4 business office building project is a super high-rise building. Building height reached 260m. The construction of internal climbing tower crane in the optimization of tower crane, construction technology support steel beam connection, connected by bolted and welded, greatly reduces the cycle of internal climbing tower crane climbing operations, both to ensure that the tower crane support steel beam in repeated dynamic load strength of connection in the environment, but also improve the progress of the whole construction project.
