1. On site construction must be carried out in accordance with the standardized construction requirements of the drawings.

2、 按照相关验收标准的要求，高强度大六角头螺栓连接副终拧完成1h后、48h内应进行终拧扭矩检查，检查数量：按节点数抽查10%，且不应少于10个；每个被抽查节点按螺栓数抽查10%，且不应少于2个。所以施工现场应在螺栓连接副终拧完成1h后、48h内提前做好检测的准备工作。

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、 扭剪型高强度螺栓连接副终拧后，除因构造原因无法使用专用扳手终拧掉梅花头者外，未在终拧中拧掉梅花头的螺栓数不应大于该节点螺栓数的5%。对所有梅花头未拧掉的扭剪型高强度螺栓连接副应采用扭矩法或转角头进行终拧掉的扭剪型高强度螺栓连接副应采用扭矩法或转角法进行终拧并用标记，且进行拧扭矩检查。检查数量：按节点数抽查10%，但不应少于10节点，被抽查节点中梅花头未拧掉的扭剪型高强度螺栓连接副全数进行终拧扭矩检查。

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、 施工单位在报检时应提前通知检测人员所报检的高强度螺栓所施加的扭矩为何种施加方法，原则上检测法应与施工法相同，所以报检前应说明是扭矩法还是转角法施工。

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、 检测过程中，施工技术员和熟悉该种施工方法的工人应在检测现场，配合检测单位检测。施工现场需提供受检构件及螺栓的设计图纸及具体参数，包括构件名称、螺栓的规格、型号、扭矩施加方式、节点位置、螺栓编号、终拧扭矩计算值。

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、 对高强度螺栓终拧扭矩的施工质量检测，应在终拧1h后、48h内应进行终拧扭矩检测。

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.
