Manufacturing method of bridge steel arch curved plate unit
The invention discloses a method for manufacturing a bent plate unit of a bridge steel arch, which belongs to the technical field of bridge steel arches, and comprises the following steps of: constructing a model in software, generating a panel expansion graph, marking mark lines such as a transverse base line and a longitudinal base line on the graph to form a panel base line graph; marking lines such as a transverse base line and a longitudinal base line are drawn on the flat panel, and then the panel is bent; a jig frame with a unified standard is further manufactured, three-dimensional coordinate points are determined according to a jig frame manufacturing drawing based on a base line diagram of the panel, the position and the height of the code plate are determined according to the three-dimensional coordinate points, the code plate is welded to the jig frame based on the three-dimensional coordinate points, and finally the panel is placed on the jig frame to weld the plate ribs. The uniformly manufactured jig frame can adapt to bent plate units of different specifications and line types, and errors of all control points can be effectively checked through space establishment of three-dimensional coordinate points, so that the precision of the plate units can be controlled, the steel arch manufacturing errors are effectively reduced, and the line types of the steel arches are guaranteed.
本发明公开了一种桥梁钢拱曲板单元的制作方法，属于桥梁钢拱技术领域，本发明在软件中构建模型，生成面板展开图，并在该图上标记了横基线、纵基线等标记线，形成面板基线图，然后在面板下料后，在平整的面板上绘制出横基线、纵基线等标记线，之后再进行面板的弯曲处理；还制作了统一标准的胎架，并根据以面板基线图为基础的胎架制作图纸确定三维坐标点，依据这些三维坐标点确定码板的位置和高度，基于此将码板焊接在胎架上，最后将面板置于胎架上焊接板肋。本发明制作统一的胎架能适应于不同规格、线型的曲板单元，且通过三维坐标点的空间建立，可有效检查各控制点的误差，从而能够控制板单元精度，有效降低钢拱制作误差，保证钢拱的线型。
