摘要
某超高层建筑标准层采用圆形密柱外框结构,平面呈圆形,立面外边线为弧形。外框柱为倾斜钢柱且存在弯折点,施工难度大且精度要求高。密柱外框施工技术,涉及构件施工顺序、吊装就位、测量校正、焊接工艺等难点。通过合理的整体与局部施工顺序、焊接工艺、临时定位等方法,保证密柱外框的安装精度。
Some super high-rise is dense column frame structure,with circular plane,curve vertical section edge.Gradient steel column of bending point,is hard to construction as high accuracy.Dense-column frame construction technology,involving construction sequence,hoisting,measurement correction,welding and other difficulties.Through reasonable sequence,welding process,and the methods of temporary constraint,ensure high construction quality.
