The剥肋滚轧直螺纹钢筋连接 is a mechanical joint for reinforcing bars that utilizes a stripping and rolling thread machine to mechanically deburr and roll-thread the bars to be connected, then joins them with threaded sleeves, capable of withstanding tensile and compressive forces. Its advantages include achieving equal strength connections, rapid construction, reliable quality, wide applicability, simple operation, and the ability to reduce costs while improving the quality of construction work. After rolling, the internal crystal lattice of the reinforcing bar is tightly arranged along the thread shape. Although the cross-sectional area of the reinforcing bar decreases after deburring, the increase in steel strength due to cold working compensation is sufficient to offset the reduction in cross-sectional area, resulting in a joint strength greater than that of the parent reinforcing bar.
