1、 現(xiàn)場施工必需按圖紙準(zhǔn)化施工要求進(jìn)行施工。
1. On site construction must be carried out in accordance with the standardized construction requirements of the drawings.
2、 按照相關(guān)驗(yàn)收標(biāo)準(zhǔn)的要求，高強(qiáng)度大六角頭螺栓連接副終擰完成1h后、48h內(nèi)應(yīng)進(jìn)行終擰扭矩檢查，檢查數(shù)量：按節(jié)點(diǎn)數(shù)抽查10%，且不應(yīng)少于10個(gè)；每個(gè)被抽查節(jié)點(diǎn)按螺栓數(shù)抽查10%，且不應(yīng)少于2個(gè)。所以施工現(xiàn)場應(yīng)在螺栓連接副終擰完成1h后、48h內(nèi)提前做好檢測的準(zhǔn)備工作。
2. According to the requirements of relevant acceptance standards, the final tightening torque of the high-strength large hexagonal head bolt connection pair should be checked within 1 hour and 48 hours after the completion of the final tightening. The inspection quantity should be 10% based on the number of nodes, and should not be less than 10; Each sampled node should be sampled 10% based on the number of bolts, and there should be no less than 2. Therefore, the construction site should prepare for testing in advance within 48 hours after the final tightening of the bolt connection pair is completed.
3、 扭剪型高強(qiáng)度螺栓連接副終擰后，除因構(gòu)造原因無法使用專用扳手終擰掉梅花頭者外，未在終擰中擰掉梅花頭的螺栓數(shù)不應(yīng)大于該節(jié)點(diǎn)螺栓數(shù)的5%。對所有梅花頭未擰掉的扭剪型高強(qiáng)度螺栓連接副應(yīng)采用扭矩法或轉(zhuǎn)角頭進(jìn)行終擰掉的扭剪型高強(qiáng)度螺栓連接副應(yīng)采用扭矩法或轉(zhuǎn)角法進(jìn)行終擰并用標(biāo)記，且進(jìn)行擰扭矩檢查。檢查數(shù)量：按節(jié)點(diǎn)數(shù)抽查10%，但不應(yīng)少于10節(jié)點(diǎn)，被抽查節(jié)點(diǎn)中梅花頭未擰掉的扭剪型高強(qiáng)度螺栓連接副全數(shù)進(jìn)行終擰扭矩檢查。
3. After the final tightening of the torsion shear type high-strength bolt connection pair, except for those who cannot use a special wrench to remove the plum blossom head due to structural reasons, the number of bolts that have not been removed from the plum blossom head during the final tightening should not exceed 5% of the number of bolts at that node. For all torsion shear type high-strength bolt connections that have not been loosened, the torque method or corner head should be used for final tightening. For torsion shear type high-strength bolt connections that have not been loosened, the torque method or corner head method should be used for final tightening and marked, and the tightening torque should be checked. Inspection quantity: Conduct a 10% spot check based on the number of nodes, but not less than 10 nodes. Conduct a final torque inspection on all torsion shear type high-strength bolt connections that have not had their plum blossom heads removed from the sampled nodes.
4、 施工單位在報(bào)檢時(shí)應(yīng)提前通知檢測人員所報(bào)檢的高強(qiáng)度螺栓所施加的扭矩為何種施加方法，原則上檢測法應(yīng)與施工法相同，所以報(bào)檢前應(yīng)說明是扭矩法還是轉(zhuǎn)角法施工。
4. When applying for inspection, the construction unit should inform the testing personnel in advance of the method of applying torque to the high-strength bolts being inspected. In principle, the testing method should be the same as the construction method. Therefore, before applying for inspection, it should be explained whether it is the torque method or the corner method for construction.
5、 檢測過程中，施工技術(shù)員和熟悉該種施工方法的工人應(yīng)在檢測現(xiàn)場，配合檢測單位檢測。施工現(xiàn)場需提供受檢構(gòu)件及螺栓的設(shè)計(jì)圖紙及具體參數(shù)，包括構(gòu)件名稱、螺栓的規(guī)格、型號、扭矩施加方式、節(jié)點(diǎn)位置、螺栓編號、終擰扭矩計(jì)算值。
5. During the testing process, construction technicians and workers familiar with this construction method should be present at the testing site and cooperate with the testing unit for testing. The construction site needs to provide design drawings and specific parameters of the inspected components and bolts, including component names, bolt specifications, models, torque application methods, node positions, bolt numbers, and final torque calculation values.
6、 對高強(qiáng)度螺栓終擰扭矩的施工質(zhì)量檢測，應(yīng)在終擰1h后、48h內(nèi)應(yīng)進(jìn)行終擰扭矩檢測。
6. The construction quality inspection of the final tightening torque of high-strength bolts should be carried out within 1 hour and 48 hours after the final tightening.
