摘要：

为了研究施铆过程中环槽铆钉预紧力的影响因素，评估钢桁梁拼接节点中环槽铆钉预紧力的稳定性，以钢桁梁悬索桥为依托工程，开展足尺节点施铆过程的铆钉预紧力监测试验. 结果表明，环槽铆钉在从刚度大的接头区域向刚度小的接头区域铆接时，适用性较好；测试的10.9级T27铆钉的铆后预紧力满足环槽铆钉预紧力要求，且优于同规格高强度螺栓；铆接过程中厚度更大的底板上的铆钉预紧力变化量比顶板有所增加，且预紧力松弛程度稍大；约束程度更高的腹板上的铆钉预紧力变化量比节点板更大. 对弦杆腹板进行铆接后48 h监测试验，结果显示铆接完成后30 h内铆钉预紧力衰减量占总衰减量的89.6%，此后预紧力的波动小于1.3%的初始值，表明环槽铆钉铆后预紧力损失较小，且逐渐趋于稳定、统一.

Abstract:

Monitoring tests on the pre-tightening force of ring groove rivets during the full-scale node riveting process were conducted by taking a steel truss suspension bridge as the supporting project to study the influencing factors of the pre-tightening force in the riveting process and evaluate the stability of the pre-tightening force of the ring groove rivets in the steel truss beam’s splicing joints. The results showed that the ring groove rivets were suitable for riveting from a joint area with high stiffness to a joint area with low stiffness. The pre-tightening force of the tested T27 rivets of grade 10.9 after riveting met the requirements for ring groove rivets and was better than that of high-strength bolts of the same specification. The pre-tightening force of the rivets on the thicker bottom plate changed more than that on the top plate during riveting, and the degree of relaxation was slightly higher. The pre-tightening force change of the rivets on the web plate with higher constraint was also larger than that on the joint plate. A 48-hour post-riveting monitoring test was carried out on the chord web. The results showed that the pre-tightening force attenuation of rivets within 30 h after riveting accounted for 89.6% of the total attenuation, and the fluctuation range of the pre-tightening force thereafter was within 1.3% of the initial pre-tightening force value, indicating that the loss of pre-tightening force after riveting was small, and the force gradually tended to be stable and uniform.
Key words: steel truss bridge    ring groove rivet    full-scale model test    splicing joint    pre-tightening force
