The invention discloses a precast pile steel bar connecting piece, and relates to the technical filed of precast piles. The precast pile steel bar connecting piece comprises an outer sleeve and a fastening bolt, wherein a positioning groove is formed in the lower end of the inner wall of the outer sleeve, a steel bar rod is movably inserted into an inner cavity of the outer sleeve, the outer wall, close to the upper end, of the steel bar rod is movably sleeved with a positioning clamping petal, an annular groove is formed in the outer wall, close to the top, of the positioning clamping petal, a gasket is movably arranged at the top of the steel bar rod, an external threaded rod is arranged at the bottom of the fastening bolt, positioning steel bar rods are movably arranged on the inner wall of the fastening bolt and the inner wall of the external threaded rod, pressing blocks are arranged at the bottoms of the positioning steel bar rods, the pressing blocks are movably pressed on the top of the gasket, a positioning groove matched with the positioning clamping petal is formed in the outer sleeve, the steel bar rods can be limited and mounted during mounting, the external threaded rods are adopted to drive the positioning steel bar rods to be directly pressed on the top of the steel bar rod, a spring type connecting structure is replaced, no elastic space exists after installation is completed, the compaction degree and tightness are guaranteed, the structure is simple, and operation is convenient.
本发明公开了预制桩技术领域的预制桩钢筋连接件，包括外套筒与紧固螺栓，所述外套筒内壁下端设置定位槽，所述外套筒的内腔活动插接钢筋杆，所述钢筋杆靠近上端外壁活动套接定位卡瓣，所述定位卡瓣靠近顶部的外壁设置环形槽，所述钢筋杆的顶部活动设置垫片，所述紧固螺栓的底部设置外螺纹杆，所述紧固螺栓与外螺纹杆的内壁均活动设置定位钢筋杆，所述定位钢筋杆的底部设置压块，且压块活动压合在垫片的顶部，在外套筒中设有与定位卡瓣匹配的定位槽，使得钢筋杆安装时可以限位安装，采用外螺纹杆带动定位钢筋杆直接压合在钢筋杆的顶部上，取代弹簧式连接结构，安装完成后没有弹性空间，保证压实度与紧密性，且结构简单，操作方便。
