Mounting and positioning method for spatial hyperbolic steel pipe truss structure
The invention relates to the field of steel structure construction, in particular to a mounting and positioning method of a spatial hyperbolic steel pipe truss structure, which comprises the following steps: segmenting a steel structure, and calculating theoretical three-dimensional coordinates of characteristic control points of truss segment ports by computer three-dimensional entity modeling; measuring the actual three-dimensional coordinates of the feature control points of the ports for installing the segments of the truss through the total station; the actual three-dimensional coordinate values of the feature control points are compared with the theoretical coordinate values, and adjustment values of the segmented port feature control points are determined; adjusting the truss according to the adjustment value of the segmented port feature control point; and adjusting the mounting precision of the end port of the tail section. The truss is integrally installed in a segmented mode, space positioning of a steel structure connector can be better controlled, and the installation precision of the truss is improved.
本发明涉及钢结构施工领域，尤其是一种空间双曲钢管桁架结构的安装定位方法，对钢结构进行分段，计算机三维实体建模计算桁架分段端口特征控制点的理论三维坐标；通过全站仪测量出桁架安装各分段端口的特征控制点的实际三维坐标；对特征控制点的实际三维坐标值与理论坐标值进行对比，确定分段端口特征控制点的调整值；根据分段端口特征控制点的调整值，调整桁架；末段端口的安装精度调整。本发明将桁架整体分段安装，能够更好的控制钢结构接口的空间定位，提高桁架的安装精度。
