Summary:The present invention relates to an anti-slip connecting nut robust to earthquake and vibration for a PHC pile. The anti-slip connecting nut comprises: a polygonal portion allowing a steel wire of a PHC file to be held thereon, and inserted into an upper end of the PHC file; a pipe expanding portion formed to have a greater diameter than that of the polygonal portion, and having a second thread coupled to a first thread of a steel material in a bolt manner; a short edge portion connecting the polygonal portion to the pipe expanding portion; a connecting portion provided on the steel wire and the polygonal portion such that the steel wire is held on the connecting portion; and an anti-slip portion provided on the polygonal portion, the pipe expanding portion, or the short edge portion to prevent the anti-slip connecting nut from slipping against the PHC pile. 본 발명은, PHC파일의 강선이 걸림결합되고 PHC파일의 두부에 삽입되는 다각부; 상기 다각부와 비교하여 큰 지름으로 형성되고 강재의 제1나사산이 볼트결합되도록 제2나사산이 형성되는 확관부; 상기 다각부와 상기 확관부를 연결하는 단턱부; 상기 강선이 걸림결합되도록 상기 강선 및 상기 다각부에 구비되는 연결부; 및 상기 PHC파일과 슬립되는 것을 방지하도록 상기 다각부, 상기 확관부 또는 상기 단턱부에 구비되는 슬립방지부를 포함하는 것을 특징으로 한다.
