Introduction of Constant Torque Electric Spanner for Bridge Construction隨著改革開放的不斷深入，的基礎設施越來越多，橋梁建設是必不可少的。系索橋是橋梁建設的主要形式。螺栓連接必須采用大六角高強度螺栓。

　　With the deepening of China's reform and opening up, China's infrastructure is increasing, and bridge construction is indispensable. Tethered bridge is the main form of bridge construction. Large hexagonal high strength bolts must be used in bolt connection.

　　大六角高強度螺栓一般為10.9級或12.9級。根據(jù)高強螺栓的施工工藝要求，高強螺栓的施工必須先緊固，再緊固。初始擰緊一般為比較大扭矩值的50% ~ 60%;比較后的緊固必須達到螺栓規(guī)定的比較大扭矩值。

　　Large hexagonal high strength bolts are generally of grade 10.9 or 12.9. According to the construction technology requirements of high-strength bolts, the construction of high-strength bolts must be tightened first and then. Initial tightening generally ranges from 50% to 60% of the maximum torque value; final tightening must reach the maximum torque value specified by the bolt.

　　大六角高強度螺栓結構，初擰緊時可選用手動扭矩扳手，固定扭矩電動扳手，比較后擰緊時必須選用前田扭矩電動扳手。

　　Large hexagonal high strength bolt structure, the first tightening can choose manual torque wrench, fixed torque electric wrench, the last tightening must choose the front field torque electric wrench.

　　橋梁施工選擇螺栓通常m2-m24和(大六角高強度螺栓,包括m2-m24比較大扭矩值通常是860海里(比較大扭矩值根據(jù)不同的摩擦系數(shù),以及不同),(比較大扭矩值通常是1700海里(比較大扭矩值根據(jù)不同的摩擦系數(shù),以及不同)早期緊,需要選擇扭矩電動扳手,設置初始擰緊力矩值,開始打螺栓,擰緊幾秒鐘后，停止電動扳手緊固，取出套筒。

　　In bridge construction, bolts are usually M2-M24 and (large hexagonal high strength bolts, including M2-M24 maximum torque value is usually 860 nautical miles (maximum torque value is based on different friction coefficients, and different), (maximum torque value is usually 1700 nautical miles (maximum torque value is based on different friction coefficients, and different) early tightening, it is necessary to select torque electric wrench, set initial tightening moment value, and start to tighten bolts. After a few seconds, stop fastening the electric wrench and take out the sleeve.

　　比較后擰緊時，需要固定扭矩電動扳手，先將扭矩值設置為螺栓的比較大扭矩值。擰緊幾秒鐘后，電動扳手停止擰緊，可以取出。

　　Finally, when tightening, it is necessary to fix the torque electric wrench. First, the value of the torque is set to the maximum value of the bolt. After tightening for a few seconds, the electric wrench stops tightening and can be taken out.

　　初擰緊時可選用通用固定力矩電動扳手，末擰緊時必須選用前田固定力矩電動扳手，扭矩大，誤差小，精度高。

　　The universal fixed moment electric wrench can be used in the initial tightening, and the front field fixed moment electric wrench must be used in the final tightening. The torque is large, the error is small and the precision is high.

　　用法:

　　Usage:

　　(1)將表盤設置為所需扭矩值，扳手套在螺栓上。
