1 High strength: The net cross-sectional area of the thick section of the pier after the thread is cut is greater than the original cross-sectional area of the steel, that is, the thread does not weaken the section, which can ensure that the joint strength is greater than the strength of the base material of the steel
2 Stable performance: The strength of the joint is not affected by the tightening torque, and the loosening of the thread or the less screwing of 2-3 buckles will not significantly affect the strength of the joint, and the influence of artificial factors and force measuring tools on the performance of the joint is excluded.
3 Fast connection speed: butt the steel bar with the connecting sleeve and tighten it. Due to the large thread pitch, the number of screwing buttons is small, and no torque wrench is needed, thus speeding up the connection.
4 High production efficiency: It takes only 30-50 seconds to cut one wire end on site, and each set of equipment can process 400-600 wire ends per shift.
