高强螺栓安装注意事项
Precautions for installation of high-strength bolts
1、当天安装的高强螺栓，当天终拧完毕；
1. The high-strength bolts installed on the same day shall be finally screwed on the same day;
2、螺栓穿入方向以方便施工为准，每个节点整齐一致；
2. The bolt penetration direction shall be subject to the convenience of construction, and each node shall be neat and consistent;
3、高强螺栓超拧时应更换，并不得重复使用；
3. Replace the high-strength bolts when they are over tightened, and do not reuse them;
4、安装中的错孔、漏孔不得用气割开孔，错孔补焊后砂轮打磨，重新钻孔；
4. Gas cutting shall not be used to cut the wrong holes and leaks during installation. After the wrong holes are repaired and welded, the grinding wheel shall be polished and the holes shall be drilled again;
5、螺栓、螺母及垫圈应放在专用工具袋内，严防高空坠落；
5. Bolts, nuts and washers should be placed in special tool bags to prevent falling from height;
6、安装用螺栓不得用高强螺栓代替。
6. Bolts for installation shall not be replaced by high-strength bolts.
电动扭剪扳手使用效果：
Use effect of electric torsion shear wrench:
1、冲击电动扳手主要是初紧螺栓的，它的使用很简单，就是对准螺栓扳动电源开关就行。电动扭剪扳手主要是终紧扭剪型螺栓的，它的使用就是对准螺栓扳动电源开关，直到把扭剪型螺栓的梅花头打断为止。
1. The impact electric wrench is mainly used to initially tighten the bolt. Its use is very simple, that is, just aim at the bolt and pull the power switch. The electric torsion shear wrench is mainly used to finally tighten the torsion shear bolt. Its use is to align the bolt and pull the power switch until the Torx head of the torsion shear bolt is broken.
2、电动定扭矩扳手既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。电动转角扳手主要也属于定扭矩扳手的一种，它的使用是先调节旋转度数，再紧固螺栓。电动角向扳手是一种专门紧固钢架夹角部位螺栓的电动扳手，它的使用和电动扭剪扳手原理一样。电动扭剪扳手拆装扭力矩大、比手工更保险可靠。方便、美观、实用、便于随车携带。广泛用于钢结构桥梁、厂房、高层建筑、化工建设等设施的施工作业。
2. The electric constant torque wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first, and then tighten the bolts. Electric angle wrench mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation first, and then tighten the bolt. The electric angle wrench is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its use is the same as that of the electric torsion shear wrench. The electric torsional shear wrench has a large torque for disassembly and assembly, which is safer and more reliable than manual. Convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridges, workshops, high-rise buildings, chemical construction and other facilities.
