3 拉压两用机械连接3.1冷锻压套管机械连接这种连接亦称横向挤压套管连接,采用无缝厚壁钢管为套管,借助专用液压设备对套管及对接钢筋端头进行冷锻压,使套管产生塑性变形,从而与钢筋杆紧密粘着形成牢固的机械连接;这种连接适用于
3 Mechanical connection for tension and compression 3.1 Mechanical connection for cold forging sleeve This connection is also called horizontal extrusion sleeve connection. It adopts seamless thick-walled steel pipe as the sleeve and uses special hydraulic equipment to cool the end of sleeve and butt joint reinforcement. Forging, plastic deformation of the sleeve, and thus closely adhered with the steel rod to form a strong mechanical connection; this connection is suitable for
