扭剪型高强螺栓使用注意事项有哪些?

What are the precautions for the use of torsional shear high strength bolts?
1、初拧扳手,可用电动扳手也可用手动带响扳手。但无论用哪种扳手施工前都进行标定,以便控制初拧扭距值。手动扳手作为终拧工具时,每班进行标定,并做好标定记录。
1. The initial tightening wrench can be either an electric wrench or a manual ring wrench. However, no matter which wrench is used, it shall be calibrated before construction to control the initial tightening torque value. When the manual wrench is used as the final tightening tool, it shall be calibrated every shift and the calibration records shall be made.
2、终柠板手:扭剪型高强螺栓是一种自标量型螺栓,因此终拧只须把高强螺栓尾部螺栓头拧掉即可,扳手不用标定。
2. Final screwing wrench: the torsional shear high-strength bolt is a self scalar bolt, so the final screwing only needs to screw off the bolt head at the tail of the high-strength bolt, and the wrench does not need to be calibrated.
3、终拧紧固时应注意,待梅花头全部套入套筒后,才能按下电动扳手开关,若内套筒只套入梅花头尺寸的1/3~1/2长度时按下电动扳手开关,将会造成梅花头打滑,并且影响套筒的使用寿命。
3. During final tightening, it should be noted that the electric wrench switch can only be pressed after all the plum blossom heads are inserted into the sleeve. If the electric wrench switch is pressed when the inner sleeve is only inserted into the length of 1/3 ~ 1/2 of the size of the plum blossom head, it will cause the plum blossom head to slip and affect the service life of the sleeve.
4、紧固时,终拧电动扳手应和构件摩擦面保持垂直,扳手倾斜是很容易导致螺栓尾部梅花头打滑,并易卡壳。
4. When tightening, the final tightening electric wrench shall be vertical to the friction surface of the component. The inclination of the wrench is easy to cause the plum blossom head at the tail of the bolt to slip and get stuck.
5、使用和保管中应注意防雨、防潮,发现有异常声音应立即停机检查。
5. Pay attention to rain and moisture protection during use and storage, and stop the machine immediately for inspection in case of abnormal sound.
