Connecting structure of prefabricated pier sections
The invention discloses a connecting structure of prefabricated pier sections. The connecting structure comprises a pier body, a corrugated pipe, a first spiral stirrup, a second spiral stirrup, a first longitudinal bar, a third spiral stirrup and a second longitudinal bar. Compared with the prior art, the prefabricated pier sections are connected in a steel bar bonding mode, shear keys similar tomortises and tenons in shape are arranged between the prefabricated pier sections in a matched mode, the pressure borne by the prefabricated pier sections is reduced, and problems of prestress loss and uneven tensile stress caused by prestress do not exist, in addition, under the combined action of the shear keys and the steel bars in the joints, the pier still has good transverse shear strength.
本发明公开了一种预制桥墩节段的连接结构，包括墩体、波纹管、第一螺旋箍筋、第二螺旋箍筋、第一纵筋、第三螺旋箍筋和第二纵筋。与现有技术相比，本发明采用粘结钢筋的方式连接预制桥墩节段，预制桥墩节段之间配有形似榫卯的剪力键，预制桥墩节段受压减小，也不存在预应力带来的预应力损失和张拉应力不均匀的问题；另外，接缝中剪力键和钢筋的共同作用，使得桥墩仍然具有良好的横向抗剪强度。
