一、轧丝锚的工作原理和构造轧丝锚具是采用冷滚压的方法在高强度圆钢筋的端部按照设计要求滚压出一定长度的螺纹,用特制螺母锚固的锚碇方法。由于在碾压时材料有一部分被滚压轮挤压入钢材的表面而同时有另一部分钢材被挤出钢材原表面。两者共同组成一个完整的螺纹。亦即钢材表面的螺纹是由钢材表层金属的塑性变形形成的。这种方法加工的螺纹,它的外径大于原有钢材的外径而螺纹的内径仍略小于原
First, the working principle and construction of rolling wire anchor Rolling anchor is the method of cold rolling in the end of high strength round bar in accordance with the design requirements of the rolling out of a certain length of the thread, anchored with a special nut anchoring method. As a part of the material is pressed into the surface of the steel by the rolling wheel while rolling and another part of the steel is extruded from the original surface of the steel. The two together form a complete thread. That is, the surface of the steel thread is formed by the plastic deformation of the steel surface metal. This method of processing the thread, it is larger than the outer diameter of the original steel and the inner diameter of the thread is still slightly smaller than the original
