鋼網架螺栓球節點用高強度螺栓拉力載荷試驗機,按GB/T16939-2016規定,將螺栓旋入專用夾具內螺紋中,使旋入的螺紋長度不少于6P、未旋入的螺紋長度不少于2P。螺栓頭下置一楔墊,夾持在HRJ-200T無振動伺服控制螺栓拉伸試驗機上,當試驗拉力達到螺栓實物機械性能規定的範圍時,螺栓應斷裂並發生在螺紋部分或螺紋與螺杆交接處。楔墊角度a=4°,其余型式尺寸按GB/T3098.1的規定。
M39~M85x4鋼網架螺栓球節點用高強度螺栓螺栓可用硬度試驗代替拉力載荷試驗。常規高強度螺栓硬度值爲32HRC~37HRC,如對試驗有爭議時,應進行芯部硬度試驗,其硬度值不低于28HRC。如對高強度螺栓硬度試驗有爭議時,應進行螺栓實物拉力載荷試驗,並以此爲仲裁試驗。
