精轧高强螺纹钢筋是一种在整根钢材表面上直接热轧出呈连续螺旋线的螺纹钢筋,直径较粗。由于它没有纵筋,钢筋的接长可用螺纹套筒连接,而且端部也可直接用螺母锚固。这种连接和锚固的方法简单可靠、施工方便,并为进一步提高钢筋强度、改进生产工艺、降低成本创造了有利条件。因此,近年来受到国内外普遍的重视,被认为是预应力高强度、大直径钢筋
Finishing high-strength rebar is a kind of direct hot rolling in the entire surface of the steel was a continuous spiral thread rebar, coarser diameter. Because it does not have longitudinal reinforcement, the length of the reinforcing bar can be connected by a threaded sleeve, and the end can also be directly anchored with a nut. The method for connecting and anchoring is simple and reliable, convenient for construction, and provides favorable conditions for further improving the strength of rebar, improving the production technology and reducing the cost. Therefore, in recent years by widespread attention at home and abroad, is considered prestressed high strength, large diameter steel
