Precast pile connecting piece, precast pile connecting structure and precast pile thereof
The invention relates to a precast pile connecting piece, a precast pile connecting structure and a precast pile thereof. The precast pile connecting piece comprises a sleeve, one end of the sleeve is open, the other end of the sleeve is provided with a sleeve bottom, and a through hole allowing a steel bar pier head to penetrate through is formed in the sleeve bottom. A restraining gasket is arranged in the sleeve, the restraining gasket comprises at least two restraining pieces arranged in the circumferential direction of the sleeve, the circumferential outer sides of the restraining pieces are jointly sleeved with an elastic piece, and the elastic piece enables the restraining pieces to have the tendency of converging towards the center so that a limiting hole with the variable diameter can be defined; the maximum diameter of the limiting hole is larger than or equal to the outer diameter of the steel bar pier head, the minimum diameter of the limiting hole is smaller than the outer diameter of the steel bar pier head, and the minimum outer diameter of the restraining gasket is larger than the hole diameter of the through hole. According to the precast pile connecting piece, head upsetting can be conducted before the steel bars are inserted into the sleeves, and the operation difficulty is lowered. The elastic piece is jointly arranged outside the restraining pieces in a sleeving mode, the situation that the restraining pieces are scattered due to lack of circumferential restraining is effectively avoided, and the reliability is improved.
本发明涉及一种预制桩连接件及其预制桩连接结构及其预制桩。预制桩连接件，包括套筒，套筒的一端开放，其另一端设有筒底，筒底上设有用于钢筋墩头穿过的通孔；套筒内设有约束垫片，约束垫片包括至少两个沿套筒周向布置的约束件，若干个约束件的周向外侧共同套设有弹性件，弹性件使若干个约束件具有向中心收束的趋势，以围成直径可变的限位孔；其中，限位孔的最大直径大于等于钢筋墩头的外径，限位孔的最小直径小于钢筋墩头的外径，约束垫片的最小外径大于通孔的孔径。本发明的预制桩连接件使得钢筋可以插入套筒之前进行墩头，降低了操作难度。通过在若干个约束件外共同套设弹性件，有效避免了约束件由于缺少周向约束而散掉，提高了可靠性。
