Steel structure bridge bolt construction quality control and maintenance method
The invention discloses a steel structure bridge bolt construction quality control and maintenance method. The method comprises the following steps that (1) a straight line is painted on the surface of a bolt through a scribing tool; (2) performing final screwing operation on the bolt, identifying a lineation part in a bolt image by adopting an image identification technology, and calculating to obtain a final screwing angle; (3) numbering bolt nodes, and storing and recording bolt final screwing angles and construction information; (4) performing statistical analysis on the bolt final screwing angle data, and preliminarily setting a threshold value of bolt screwing qualification; (5) further determining a threshold value of screwing qualification in combination with a method of ultrasonically measuring the pretension force of the bolt; (6) according to the threshold value of bolt screwing qualification determined in the step (5), bolt nodes exceeding the threshold value are subjected to replacement or supplementary screwing treatment; and (7) after bolt coating is completed, scribing is conducted again. According to the invention, the screwing quality of the high-strength bolt is improved, the final screwing corner information of the bolt is digitally recorded, and the overall screwing quality of the bolt is improved.
本发明公开了一种钢结构桥梁螺栓施工质量管控及养护方法，包括以下步骤：(1)采用划线工装在螺栓表面涂画一条直线；(2)对螺栓进行终拧作业，并采用图像识别技术，识别螺栓图像中划线部分，计算得到终拧角度；(3)对螺栓节点进行编号，存储记录螺栓终拧角度和施工信息；(4)对螺栓终拧角度数据进行统计分析，初步设定螺栓施拧合格的阈值；(5)结合超声测螺栓预拉力的方法，进一步确定施拧合格的阈值；(6)依据步骤(5)中确定的螺栓施拧合格的阈值，对超出阈值的螺栓节点进行替换或补拧处理；(7)螺栓涂装完成后，再次划线。本发明提高了高强螺栓施拧质量，将螺栓终拧转角信息进行数字化记录，提高了螺栓施拧的整体质量。
