Dry joint structure of bridge pier column and friction type pier column of passage special for passenger car
The invention discloses a bridge pier column for a passage special for a passenger car. The bridge pier column comprises a pipe pile, a bearing platform, a pier column body and a cover beam. A hollow prefabricated pier column is adopted in the joint structure, and main reinforcements distributed in the pier column in the vertical direction comprise prestressed steel bars; the prefabricated I-shaped bent cap comprises a vertical web, an upper wing plate, a lower wing plate and inner ribs. The middle of the lower wing plate is correspondingly connected with the pier column, a first prefabricated hole corresponding to the locking section is formed in the lower wing plate, and a second prefabricated hole is formed in the vertical web plate; wherein the locking section comprises a first locking section and a second locking section, the first locking section penetrates through the first prefabricated hole, a pre-tightening nut is further screwed at the free end of the first locking section, and the pier column and the cover beam are locked by the pre-tightening nut to provide a bearing force; and the second locking section extends into the second prefabricated hole and is filled in the second prefabricated hole.
本发明公开了一种小客车专用通道桥梁墩柱包括管桩、承台、墩柱以及盖梁；其接头结构采用空心的预制墩柱，所述墩柱内沿竖向分布的主筋包括预应力钢棒；预制的工字型盖梁，包括竖向腹板、上翼板、下翼板以及內筋；所述下翼板的中部与所述墩柱对应连接，所述下翼板上开设有与所述锁紧段对应的第一预制孔，所述竖向腹板上开设有第二预制孔；其中，所述锁紧段包括第一锁紧段以及第二锁紧段，所述第一锁紧段贯穿所述第一预制孔，所述第一锁紧段的自由端还施拧有预紧螺母，所述预紧螺母锁紧所述墩柱以及所述盖梁，以提供承载力；所述第二锁紧段伸入所述第二预制孔，并灌填在所述第二预制孔内。
