①高强度螺栓连接副的施拧顺序和初拧、复拧扭矩应符合设计要求和现行行业标准《钢结构高强度螺栓连接的设计施工及验收规程》JGJ82的规定。
① The tightening sequence, initial tightening and re-tightening torque of high-strength bolt connection pair shall comply with the design requirements and the current national industrial standard JGJ82 Code for Design, Construction and Acceptance of High-strength Bolt Connections of Steel Structures.
②高强度螺栓连接副终拧后，螺栓丝扣外露应为2～3扣，其中允许有10%的螺栓丝扣外露1扣或4扣。检查数量：按节点数抽查5%，且不应少于10个。
② After the final tightening of the high-strength bolt connection pair, the exposed bolt threads shall be 2-3 threads, and 10% of the bolt threads are allowed to be exposed 1 or 4 threads. Inspection quantity: spot check 5% according to the number of nodes, and no less than 10.
③高强度螺栓连接摩擦面应保持干燥、整洁，不应有飞边、毛刺、焊接飞溅物、焊疤、氧化铁皮、污垢等，除设计要求外摩擦面不应涂漆。
③ The friction surface of high-strength bolt connection shall be kept dry and clean, free of flash, burr, welding spatter, weld scar, scale, dirt, etc. The friction surface shall not be painted except as required by the design.
④高强度螺栓应自由穿入螺栓孔。高强度螺栓孔不应采用气割扩孔，扩孔数量应征得设计同意，扩孔后的孔径不应超过1.2d（d为螺栓直径）。
④ High-strength bolts shall be freely threaded into bolt holes. High strength bolt holes shall not be reamed by gas cutting. The number of reamed holes shall be approved by the design. The hole diameter after reaming shall not exceed 1.2d (d is the bolt diameter).
⑤螺栓球节点网架总拼完成后，高强度螺栓与球节点应紧固连接，高强度螺栓拧入螺栓球内的螺纹长度不应小于1.0d（d为螺栓直径），连接处不应出现有间隙、松动等未拧紧情况。
⑤ After the completion of the assembly of the bolted ball joint grid frame, the high-strength bolts and the ball joints shall be firmly connected. The length of the thread of the high-strength bolts screwed into the bolt ball shall not be less than 1.0d (d is the bolt diameter). There shall be no gap, looseness and other untightening conditions at the connection.
