摘要
本文梳理了钢结构用高强度螺栓的工程应用和复检要求,重点研究高强度螺栓中大六角头型的扭矩系数、扭剪型的预拉力、螺栓连接的钢板摩擦面抗滑移系数等参数的试验方法,讨论了试验过程注意要点及螺栓连接副的工程施工经验,对做好施工前螺栓连接副的质量检测对保证钢结构建设质量具有重要意义。
This paper combs the engineering application and re inspection requirements of high strength bolts for steel structure, This paper key researchs the test methods of torque coefficient of large hexagon head type, pre tension of torsional shear type and anti slip coefficient of friction surface of bolted steel plate, The key points in the test process and the construction experience of bolt connection pair are discussed.The quality inspection of bolt connection pair before construction is of great significance to ensure the quality of steel structure construction.
