5.3 install high-strength bolts, friction surface components should be kept dry electric torsional shear wrench manufacturer shall work in the rain. 5.4 strength bolts tightened, except for applying torque on the nut. Only when space is limited, allowed tighten bolts. 5.5 high strength bolts tightened should be divided into early twist, the final twist. For large node should be divided into early twist, double twist, the final twist. Early twist torque is about 50% of the construction of torque, torque is equal to the initial complex twist twist torque. In order to prevent the omission of Jinan electric torsional shear wrench, unscrew the beginning of the high-strength bolts or after re-tighten, you should use color painted mark on the nut. For high strength bolts after the final twist, and then another color painted mark on the nut. 5.6 In the early strength bolts twist, twist and final twist when complex domestic electric torsional shear wrench, bolt connections shall be applied in a certain order tighten general population should be central bolt tightening sequence outward. 5.7 twist early strength bolts, complex twist, the final twist should be completed the same day. Can not be completed in the next day after the final twist. Construction quality inspection records strength bolts should have the following original inspection acceptance records, and provide supervision and suppliers: a, high strength bolts reinspection data; b, anti-slip coefficient test data; c, early twist torque Tighten end torque, the torque wrench to check the data; d, construction quality inspection acceptance records. The above data and detailed data records to a specific piece of equipment. Also includes inspection and experimenter's name and time data. 7 high strength bolts connecting 7.1 rustproof paint strength bolts tightened after passing inspection and acceptance of the main structure and gap junctions connecting plate seam timely use of silicone sealant. Maternal strength bolts junction of 7.2 after passing inspection, the connecting plate, high strength bolts should be promptly painted rust in order to avoid corrosion.
