Spatial multi-dimensional angle control method for inward-inclined basket arch bridge
The invention relates to a spatial multi-dimensional angle control method for an inward-inclined basket arch bridge. The method comprises the following steps of firstly, equal-angle conversion in a main truss connecting direction is carried out, and then equal-angle conversion in a coupling connecting direction is carried out; the equal-angle conversion of the main truss connecting direction and the equal-angle conversion of the coupling connecting direction both take the main truss connecting direction as the length direction of the rod piece and take the length direction as the longitudinal datum line of the rod piece; a straight line perpendicular to the longitudinal datum line is made at the datum line which passes through the original point and is perpendicular to the longitudinal datum line of the rod piece to serve as a transverse datum line, a plane-coordinate system is established with the longitudinal datum line and the transverse datum line, an intersection point serves as a coordinate original point, and then three-dimensional lofting is conducted with an angle of the main truss connecting direction as the basis; and a coordinate value of the measurement point is determined in the main truss connection direction. The method is reasonable and simple in conception, can guarantee manufacturing precision of the spatial multi-dimensional angle, improves the construction quality and progress, and guarantees smooth implementation of a construction target.
本发明涉及一种内倾式提篮拱桥空间多维角度控制方法，其先进行主桁连接方向等角度转化，再进行联结系连接方向等角度转化；所述主桁连接方向等角度转化和所述联结系连接方向等角度转化均是以主桁连接方向为杆件的长度方向，并以该长度方向作为杆件的纵向基准线，在过原点与杆件的纵向基准线相垂直的基准线处做一条与纵向基准线相互垂直的直线作为横向基准线，以纵向基准线和横向基准线建立平面坐标系，交点为坐标原点，然后以主桁连接方向的角度为依据，三维放样后，确定出主桁连接方向的测量点的坐标值。本发明构思合理、简单，能保证空间多维角度制造精度，提高施工质量和进度，确保施工目标顺利实现。
