上海科技馆工程主楼平面呈半圆型,立面呈螺旋上升型,主轴线为圆弧线和放射线。对于科技馆这样的建筑,如果土建工程中轴线位置稍有偏差,则屋架钢结构及中央大球体等复杂结构就无法正确安装。钢结构预埋件安装偏差为5mm,科技馆主楼的最大半径为163.5m,怎样保证结构定位放线的精确是摆在科技馆施工技术人员面前的一大难题。为克服这一困难,我们采用 AutoCAD 软件配合全站仪进行结构的平面
The main building of the Shanghai Science and Technology Museum project is semi-circular in plan. The elevation of the building is spiral-shaped. The main axis is circular arc and radiation. For such buildings as science and technology museum, if the axial position of civil engineering slight deviation, the roof steel structure and the central ball and other complex structures can not be properly installed. Steel structure embedded parts installation deviation of 5mm, the largest radius of the main building of Science and Technology Museum is 163.5m, how to ensure the precise positioning of the structure positioning is placed in front of science and technology museum construction technicians a major problem. To overcome this difficulty, we use AutoCAD software with total station structure of the plane
