Torque method or angle method shall be used for final tightening and marking of all high-strength torsional shear bolt connection pairs whose plum heads have not been unscrewed, and the final tightening torque shall be checked according to the provisions in Article 2 above.
檢查數(shù)量：按節(jié)點數(shù)抽查10%，但不應少于10個節(jié)點，被抽查點中梅花頭未擰掉的扭剪型高強度螺栓連接副全數(shù)進行終擰扭矩檢查。
Inspection quantity: spot check 10% according to the number of nodes, but not less than 10 nodes. The final tightening torque shall be checked for all torsional shear type high-strength bolt connection pairs whose plum heads have not been unscrewed.
