1、初擰扳手，可用電動(dòng)扳手也可用手動(dòng)帶響扳手。但無(wú)論用哪種扳手施工前都必須進(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)，必須每班進(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 type of wrench is used for construction, calibration must be carried out in order to control the initial tightening torque value. When using a manual wrench as a final tightening tool, it is necessary to calibrate it every shift and keep calibration records.
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 tightening wrench: The torsion shear high-strength bolt is a self scalar type bolt, so the final tightening only needs to unscrew the tail bolt head 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(kāi)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(kāi)關(guān)，將會(huì)造成梅花頭打滑，并且影響套筒的使用壽命。
3. When final tightening, attention should be paid to pressing the electric wrench switch only after all the plum blossom heads are inserted into the sleeve. If the inner sleeve is only inserted into 1/3 to 1/2 of the size of the plum blossom head, pressing the electric wrench switch 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 should be kept perpendicular to the friction surface of the component. If the wrench is tilted, it can easily cause the end 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. During use and storage, attention should be paid to rain and moisture prevention. If any abnormal sounds are found, the machine should be immediately shut down for inspection.
