Construction method for improving absolute position acquisition precision of original structure column grid
The invention discloses a construction method for improving the absolute position acquisition precision of an original structure column grid. The construction method comprises the following steps: 1, introducing control points into an existing building; 2, mounting a laser range finder in the existing building in a sliding manner; 3, when the laser range finder slides, projecting two points to each cylindrical surface of each original structure column position to form laser receiving points; 4, acquiring absolute plane position coordinates of each laser receiving point through a laser range finder; 5, two laser receiving points on each cylindrical surface are connected to form a laser positioning line, extension lines of the laser positioning lines on two adjacent cylindrical surfaces intersect, and the extension lines of the laser positioning lines on all cylindrical surfaces on the original structure column position enclose to form a section contour of the original structure column position; and calculating the absolute plane position coordinates of the original structure column position through the absolute plane position coordinates of all the laser receiving points. The invention relates to the technical field of existing building reconstruction and extension projects, and can solve the problems of low absolute position acquisition precision and time and labor waste of an original structure column grid in the prior art.
本发明公开了一种提高原结构柱网绝对位置采集精度的施工方法，包括步骤：1、在既有建筑中引入控制点；2、在既有建筑中滑动安装激光测距仪；3、激光测距仪滑动时向每根原结构柱位的每个柱面上投射两个点，形成至激光接收点；4、通过激光测距仪获取每个激光接收点的绝对平面位置坐标；5、每个柱面上的两个激光接收点连成激光定位线，相邻两个柱面上的激光定位线的延长线相交，原结构柱位上所有柱面上的激光定位线延长线围合形成原结构柱位的截面轮廓；通过所有激光接收点的绝对平面位置坐标推算原结构柱位的绝对平面位置坐标。本发明涉及既有建筑改扩建工程技术领域，能够解决现有技术中原结构柱网绝对位置采集精度低和费时费力的问题。
