Longitudinal-rib-free deformed steel bar self-locking threaded connector
The invention provides a longitudinal-rib-free deformed steel bar self-locking threaded connector, and relates to the technical field of engineering construction.The longitudinal-rib-free deformed steel bar self-locking threaded connector comprises a sleeve, the sleeve is integrated or split, a first deformed steel bar and a second deformed steel bar are screwed into the two ends of the interior of the sleeve respectively, and discontinuous external threads are arranged on the outer side of the first deformed steel bar and the outer side of the second deformed steel bar respectively; a spiral trapezoidal thread is arranged on the inner surface of the sleeve, the spiral trapezoidal thread is matched with the discontinuous external thread, and the spiral trapezoidal thread is a through thread which is directly tapped from one end face to the other end face in the sleeve; intermittent external threads on the surface of the hot-rolled deformed steel bar are directly applied to be matched with spiral trapezoidal threads in the sleeve to form threaded connection, head-to-head rigid static connection between the first deformed steel bar and the second deformed steel bar is achieved, the procedure of thread threading and reprocessing on a steel bar connector is avoided, the building construction operation process is simplified, and the construction efficiency is improved. And the time cost of engineering construction and the post-processing cost of engineering parts are reduced.
本发明提供了无纵肋螺纹钢自锁螺纹连接器，涉及工程建筑技术领域，包括套筒，所述套筒为一体式或分体式，所述套筒内部的两端分别拧入第一螺纹钢和第二螺纹钢，所述第一螺纹钢、第二螺纹钢的外侧均设有间断外螺纹，所述套筒的内表面设有螺旋梯形螺纹，所述螺旋梯形螺纹与所述间断外螺纹相适配，所述螺旋梯形螺纹为套筒内部一端面直接攻丝到另一端面的通螺纹；本发明直接应用热轧螺纹钢表面的间断外螺纹适配套筒内部的螺旋梯形螺纹，形成螺纹连接，实现第一螺纹钢第二螺纹钢之间对头刚性静连接，避免了对钢筋接头进行螺纹套丝再加工的工序，简化建筑施工操作流程，降低工程建筑的时间成本与工程用件的后加工成本。
