湖北省晴川饭店主楼为24层,高88.1米的塔型建筑,框架筒体结构,施工场地较狭窄,垂直度要求不超过50毫米。我们采用了三点激光铅直投测方法控制高层建筑施工垂直度,操作简便迅速、精度高、投测结果可靠。 一、原理 控制建筑物各层柱列轴线垂直位移,是控制高层建 The main building of Qingchuan Hotel in Hubei Province is a 24-storey, 88.1-meter-tall tower building with a frame and tube structure. The construction site is relatively narrow, and the verticality requirement does not exceed 50 mm. We adopted a three-point laser vertical projection measurement method to control the verticality of high-rise building construction. The operation is simple and rapid, with high accuracy and reliable test results. I. Principle Controlling the vertical displacement of column axes of buildings in each layer is to control the high-rise building
