Finish rolling hollow twisted steel bar structure and anchor rod structure comprising same
The invention discloses a finish rolling hollow twisted steel bar structure and an anchor rod structure comprising the same. The finish rolling hollow twisted steel bar structure comprises a hollow structure and an external thread structure. The hollow structure is arranged in the finish rolling hollow twisted steel structure, and the hollow structure and the finish rolling hollow twisted steel structure are coaxially arranged; the external thread structure is arranged on the outer wall of the finish rolling hollow twisted steel bar structure and can be used for being in threaded connection with the matched internal thread structure. According to the finish rolling hollow threaded steel bar structure, a part of a secondary grouting flowback channel can be formed through the hollow structure of the finish rolling hollow threaded steel bar structure, so that the functions which can be completed by common finish rolling threaded steel bar can be completed, and the manufacturing difficulty and the manufacturing cost of an anchor rod structure can be reduced.
本发明公开了一种精轧中空螺纹钢筋结构及包含该结构的锚杆结构，精轧中空螺纹钢筋结构包括中空结构以及外螺纹结构；中空结构设置在精轧中空螺纹钢筋结构内，中空结构与精轧中空螺纹钢筋结构同轴设置；外螺纹结构设置在精轧中空螺纹钢筋结构的外壁上，外螺纹结构能够用于与相匹配的内螺纹结构进行螺纹连接。本发明的精轧中空螺纹钢筋结构，可以通过自身的中空结构形成二次注浆返排通道的一部分，从而既可以完成普通精轧螺纹钢能够完成的功能外，还可以减少锚杆结构的制造难度以及制造成本。
