摘要
基于螺纹联接原理。本文对螺纹联接副的性能进行了分析，结合钢网架螺纹联接的现状，指出TGB／T169369—1997标准中螺距系列选择存在的不足，给出了钢网架用高强度螺栓修正螺距系列。并对此系列推行的技术可行性进行了论证。
Based on the principle of srew thread joint, this paper analyzes the properties of screw joint pairs, combining with current situation of screw joint for space grid structures ,points out the disadvantages of pitches selecting in standard Of GB/T16939, a modified seris of pitch of high strength bolts for joints of space grid structures is introduced.finally, the technical feasibility of this seris carrying out is proved.
