The invention relates to a connecting device for a precast pile, and belongs to the technical field of precast pile connection. The connecting device comprises a concrete pile; pile head steel bars are uniformly distributed at the pile top of the concrete pile; a sleeve is arranged at the end, away from the concrete pile, of each pile head steel bar; a first connecting hole and a second connecting hole communicating with the first connecting hole are formed in each sleeve; a pile head steel bar upset head is fixed at the end, away from the concrete pile, of each pile head steel bar and is clamped in the corresponding second connecting hole; an anchoring steel bar is arranged on the side, away from the corresponding pile head steel bar, of each sleeve; a center hole screw is arranged at the end, close to the corresponding sleeve, of each anchoring steel bar; a third connecting hole is formed in each center hole screw; the anchoring steel bars penetrate through the third connecting holes; anchoring steel bar upset heads for preventing the anchoring steel bars from disengaging from the third connecting holes are fixed to the ends, close to the pile head steel bars, of the anchoring steel bars; and the ends, close to the sleeves, of the center hole screws are inserted into the second connecting holes and are detachably connected with the sleeves. The connecting device has the effect of improving the connecting stability of the concrete pile and a bearing platform.
本申请涉及一种预制桩用连接装置，属于预制桩连接的技术领域，其包括混凝土桩，混凝土桩的桩顶均匀分布有桩头钢筋，桩头钢筋远离混凝土桩的一端设置有套筒，套筒上开设有第一连接孔和与第一连接孔连通的第二连接孔，桩头钢筋远离混凝土桩的一端固定有桩头钢筋镦头，桩头钢筋镦头卡在第二连接孔内；套筒远离桩头钢筋的一侧设置有锚固钢筋，锚固钢筋靠近套筒的一端设置有穿心孔螺丝，穿心孔螺丝上开设有第三连接孔，锚固钢筋贯穿第三连接孔，锚固钢筋靠近桩头钢筋的一端固定有防止锚固钢筋从第三连接孔脱出的锚固钢筋镦头，穿心孔螺丝靠近套筒的一端插入到第二连接孔中并与套筒可拆卸连接。本申请具有提高混凝土桩与承台连接的稳定性的效果。
