①高強度螺栓連接副的施擰順序和初擰、復擰扭矩應符合設計要求和現(xiàn)行行業(yè)標準《鋼結構高強度螺栓連接的設計施工及驗收規(guī)程》JGJ82的規(guī)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高強度螺栓連接副終擰后，螺栓絲扣外露應為2～3扣，其中允許有10%的螺栓絲扣外露1扣或4扣。檢查數(shù)量：按節(jié)點數(shù)抽查5%，且不應少于10個。
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高強度螺栓連接摩擦面應保持干燥、整潔，不應有飛邊、毛刺、焊接飛濺物、焊疤、氧化鐵皮、污垢等，除設計要求外摩擦面不應涂漆。
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高強度螺栓應自由穿入螺栓孔。高強度螺栓孔不應采用氣割擴孔，擴孔數(shù)量應征得設計同意，擴孔后的孔徑不應超過1.2d（d為螺栓直徑）。
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螺栓球節(jié)點網(wǎng)架總拼完成后，高強度螺栓與球節(jié)點應緊固連接，高強度螺栓擰入螺栓球內的螺紋長度不應小于1.0d（d為螺栓直徑），連接處不應出現(xiàn)有間隙、松動等未擰緊情況。
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.
