高层建筑激光竖向定位技术

The laser vertical positioning technique of high-rise building

高层建筑垂直度的控制直接影响着工程质量和工程进度 ,着重阐述了利用激光经纬仪如何进行高层建筑垂直度的控制 ,介绍了施工过程中在首层预埋钢板设置投测点 ,然后在所测楼面放置接收靶进行投测 ,从而完成竖向控制的方法 ,总结了采用激光经纬仪进行轴线投测的优点及施工中的注意事项。

The verticality control of high rise building directly influence the quality and progress of engineering. In this paper the thing that how to use laser theodolite to control the verticality of high rise building is illustrated. The setting up of the drawn point on first floor preenbedded steel board and the placement of the receive target on the measures floor are introduced. so the vertical controlling method is completed. At last the advantages and matters needing attention of using laser theodolite to conduct axial measurement are summarized.
