The invention discloses a precast pile bolt connection stamping end plate which comprises stamping end plates which are arranged at the ends of two opposite precast piles and are symmetrical in position, a plurality of stamping parts are arranged on the stamping end plates, and pier head penetrating holes and connecting holes with internal threads are formed in the stamping parts in a penetrating mode. The connecting hole is communicated with the extending space located in the precast pile, the pier head penetrating hole of the stamping part replaces a pier head hole, the thickness of the end plate meets the shear strength of the pier head penetrating hole, meanwhile, the stamping part can improve the overall rigidity of the end plate, the thickness of the end plate can be greatly reduced on the premise that the performance is not reduced, and the service life of the end plate is prolonged. A groove formed after the end plate is punched can also serve as a hand hole for bolt connection, the grooved connecting piece drives the lower nut to continue to move downwards after being completely screwed into the lower nut through a one-way wrench, screwing is stopped until friction force generated by pretightening force drives the upper nut to rotate, and bolt breakage caused by too large pretightening force is avoided.
本发明公开了一种预制桩螺栓连接冲压端板，包括置于相对的两个预制桩端部的位置对称的冲压端板，所述冲压端板上设置有若干个冲压部，所述冲压部上贯穿有墩头穿孔以及含有内螺纹的连接孔，所述连接孔与位于所述预制桩内部的延伸空间连通，冲压部的墩头穿孔取代墩头孔，端板厚度满足墩头穿孔抗剪强度即可，同时冲压部还能提高端板的整体刚度，端板厚度可以在性能不降低的前提下大大降低，端板冲压后形成的槽还能作为螺栓连接的手孔，开槽的连接件通过单向扳手完全拧入下螺母后，带动下螺母继续向下运动，直到预紧力产生的摩檫力带动上螺母转动后停止拧紧，避免预紧力过大造成螺栓断裂。
