大型展馆复杂钢结构拆除方案设计与施工

Design and implementation of complex steel structure dismantling plan of large exhibition hall

依据对展览中心的结构特征分析,有针对性地制定了大厅飘蓬分跨拆解拆除法、网架拱3机抬吊整体拆除法、门式刚架"挂篮人工分割+吊车吊挂"吊拆法,通过层级协同管理制度的执行,按时、安全地完成了拆除任务,其技术和方法有较好的工程应用价值。

Based on the analysis of structural characteristics of the exhibition center,we formulated dismantling plans accordingly.The hall cantilevered canopy was dismantled in batches;Steel arch was hung&lifted in whole by3cranes;and portal frame was manually split by cradle worker sand later removed via crane.With collaborative management,we completed project safely&on schedule.The techniques and methods have good engineering application value.
