Connecting structure of prefabricated bent cap and prefabricated pier and construction method of connecting structure
The invention discloses a connecting structure of a prefabricated bent cap and a prefabricated pier and a construction method of the connecting structure, and relates to the technical field of prefabricated bridge assembly.The connecting structure comprises the prefabricated pier and the prefabricated bent cap assembled at the top end of a prefabricated pier column, and the upper end face of the prefabricated pier integrally extends upwards to be provided with a plurality of reserved steel bars; a plurality of reserved cavities allowing the reserved steel bars to vertically stretch into are correspondingly formed in the assembling position of the prefabricated cover beam, the reserved cavities are of big-end-up structures penetrating through the prefabricated cover beam up and down, and after the prefabricated cover beam and the prefabricated pier are assembled, grouting materials are poured into the reserved cavities from top to bottom. The reserved cavity formed in the prefabricated bent cap is in a big-end-up form, reserved steel bars of the prefabricated pier can be fully anchored, and the aim that the stress performance of the joint is equal to that of cast-in-place is achieved. Compared with the prior art, a grouting sleeve and a grouting corrugated pipe can be omitted, and the connecting joint cost is reduced.
一种预制盖梁和预制桥墩的连接结构及其施工方法，涉及预制桥梁装配技术领域，包括预制桥墩、以及装配在预制墩柱顶端的预制盖梁，所述预制桥墩上端面一体向上延伸设置有若干预留钢筋，所述预制盖梁的装配位对应设置有若干允许每一预留钢筋竖直伸入的预留空腔，所述预留空腔为上下贯穿所述预制盖梁的上大下小结构，所述预制盖梁与预制桥墩装配后，所述预留空腔内自上往下灌注灌浆料。本发明预制盖梁内设置的预留空腔呈上大下小的形式，能够对预制桥墩预留钢筋充分锚固，达到节点受力性能等同现浇目标。本发明较于现有技术可省去灌浆套筒和灌浆波纹管，降低连接节点成本。
