温州世贸中心屋顶异形钢结构三维空间测量定位技术

Three-dimensional Space Position Measurement Technology for the Special Shaped Steel Roof in Wenzhou World Trade Center

温州世贸中心是全国钢筋混凝土筒中筒结构第一高楼。建筑高度333.333m,主楼74层,66层以上屋顶钢结构呈莲花瓣造型。对其屋顶钢结构安装中的重点、难点进行了分析,从钢结构空中安装定位测量控制方面进行了描述,提出了三维空间定位测量控制方法,进行了该方法的实际应用与控制研究,最终达到了安装所需的高精度控制要求,保证了安装质量,提高了工效,降低了成本,缩短了工期,解决了超高层屋顶异形复杂钢结构空中测量控制难的问题。

Wenzhou World Trade Center is the tallest reinforced concrete tube in tube structure in China.The height of the building is 333.333m and the main building has 74 floors,which is the steel structure with shape of lotus flower above the 66th floor.The author analyzes the importance and difficulties in the construction process of the steel lotus flower,especially the high-sky position measurement control of the steel roof.The author proposes the method of three-dimensional high-sky position measurement control in the building.By the practical application and research,the method achieves the high-precision control requirements,ensures installation quality,improves efficiency,reduces costs and shortens the construction period,and solves the difficult problems of measurement control of complex shaped high-rise steel structure roof aerial.
