Electric power steel tower factory power plant steel rod steel rod steel rod base requirements and maintenance

With the power and steel bar market continues to promote progress, more people began to pay attention to structural quality steel bars, so this requires us to further increase the professionals handle the power requirements of the internal structure of steel rods. Material power steel bar used generally and 16Mn, Q235, its cross-sectional shape of the round, dodecagon shaped, steel rod mostly tapered shaft, under normal circumstances, the slope of the linear rod generally taken to be 1 / 75 ~ 1 / 70,30 ° angle is taken as 1 / 65,90 ° angle is taken as 1/35. Steel rod tip diameter is generally 200 ~ 260mm, it can be calculated and determined in accordance with the design, used mostly steel rod tip diameter 230mm. Multi-rod segments Connection with flange connection socket type two, can be selected according to the actual situation. Requirements for straight steel rod deflection should not exceed 5 ‰, angle steel bars should not exceed 2%. Steel rod base mostly chunk stepped reinforced concrete foundation, the basis of the special section may also be other types of pile foundation and so on. Power steel bar after a period of use, the maintenance to its staff must strictly abide by the rules, pay attention to wear protective safety equipment at high altitude; the best is the off the job, pay attention to security issues, to prevent electric shock, overhaul qualified Power steel rod can continue to be put into use.
