轴线控制是建筑结构施工关键性的一环。规范要求现浇框架的轴线偏差,5米以下不大于10毫米,全高不大于15毫米。如果不精心操作是难以达到的。控制高层现浇框架轴线的方法很多,现就用经纬仪控制轴线的方法简述如下: 1.定位放线时首先做好长久性标志定位放线时必须用油漆将纵横轴线标记在临近永久性房屋的墙面、散水或附近围墙等建筑物上,并应在放线时埋设混凝土桩,以便在桩上端做轴线符号,作为标准轴线
Axis control is a key part of building construction. The specification requires that the deviation of the axis of the cast-in-place frame is less than 5 meters and less than 10 millimeters, and the total height is no more than 15 millimeters. It is difficult to achieve without careful operation. There are many ways to control the axis of cast-in-place cast-in-place frames. The method of using theodolite to control the axes is briefly described as follows: 1. When positioning the wires, the long-term mark must be positioned first. When laying wires, the vertical and horizontal axes must be marked with paint near the permanent houses. On concrete walls, loose water, or nearby walls, and concrete piles should be buried during laying so that axis symbols can be made at the top of the pile as a standard axis.
