扭剪型高強(qiáng)螺栓使用注意事項(xiàng)有哪些？
What are the precautions for the use of torsional shear high strength bolts?
1、初擰扳手，可用電動(dòng)扳手也可用手動(dòng)帶響扳手。但無論用哪種扳手施工前都進(jìn)行標(biāo)定，以便控制初擰扭距值。手動(dòng)扳手作為終擰工具時(shí)，每班進(jìn)行標(biāo)定，并做好標(biāo)定記錄。
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、終檸板手：扭剪型高強(qiáng)螺栓是一種自標(biāo)量型螺栓，因此終擰只須把高強(qiáng)螺栓尾部螺栓頭擰掉即可，扳手不用標(biāo)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、終擰緊固時(shí)應(yīng)注意，待梅花頭全部套入套筒后，才能按下電動(dòng)扳手開關(guān)，若內(nèi)套筒只套入梅花頭尺寸的1/3～1/2長(zhǎng)度時(shí)按下電動(dòng)扳手開關(guān)，將會(huì)造成梅花頭打滑，并且影響套筒的使用壽命。
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、緊固時(shí)，終擰電動(dòng)扳手應(yīng)和構(gòu)件摩擦面保持垂直，扳手傾斜是很容易導(dǎo)致螺栓尾部梅花頭打滑，并易卡殼。
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、使用和保管中應(yīng)注意防雨、防潮，發(fā)現(xiàn)有異常聲音應(yīng)立即停機(jī)檢查。
5. Pay attention to rain and moisture protection during use and storage, and stop the machine immediately for inspection in case of abnormal sound.
