信息化预拼装在钢结构成品检验中的应用

我国的钢结构随着建筑业的高速发展应用领域也得到不断地扩大,复杂钢构件的成品检验成为了工程技术中的瓶颈。本文结合上海中心大厦项目的第三道环带桁架钢构件的信息化预拼装的操作过程,论述了综合利用三维建模软件对复杂空间杆件放样定位优势,以及全站仪精密测量空间坐标的特点,有效地解决复杂钢构件的检测难题,提高复杂钢构件制作精度,保障现场安装顺利进行。

The Application of Information Technology Pre-Assembly in Finished Product Inspection ＆ Test of Steel Structures

With the rapid development of construction industry in China, the applications of steel structure in construction industry also continues to expand. The finished product inspection ＆ test of complex steel components has become a bottleneck in engineering technology. Combining with the information technology pre-assembly of the third ring steel truss components in Shanghai Center Tower project, this thesis describes the advantages of Integrat- ed utilization of three-dimensional modeling software in complex space bar lofting and the features of precision meas- urement of space coordinates by using total station instrument. It effectively solve the complex problem of inspection ＆ test of steel components and improve fabrication precision of complex steel components to ensure smooth erection at site.
