钢筋锥螺纹连接技术，包括四个工序工程，即钢筋下料；锥螺纹连接套的加工；挤压钢筋端锥螺纹的加工及工地上钢筋连接。1钢筋下料按照规范，钢筋应调直，切口端面与钢筋轴线垂直，不得有马蹄形或挠曲，不得用气割下料．则钢筋只能用两种方法下料，即无齿锯或切断机下料。2连接 Reinforced steel taper thread connection technology, including four process engineering, that is, rebar material; processing of taper thread connecting sleeve; processing of steel bar end tapered thread and reinforcement connection on construction site. 1 According to the specifications, the steel bars should be straightened, and the end face of the steel bar should be straightened with the axis of the bar. There must be no horseshoe or flexure, and the steel should not be cut with gas. The rebar can only be unloaded in two ways, ie without a tooth saw or cutting machine. 2 connection
