Bridge pier connecting structure based on threaded connection
The invention provides a bridge pier connecting structure based on threaded connection. The bridge pier connecting structure comprises a lower pier column and an upper pier column, wherein the lower pier column is made of concrete, the top of the lower pier column is provided with a lower end plate and a connecting hole, the connecting hole penetrates through the lower end plate and extends into the lower pier column, and a lower threaded steel sleeve is arranged in the connecting hole and is provided with an internal thread structure; the upper pier column is made of concrete, an upper end plate and a connecting rod are arranged at the bottom of the upper pier column, the connecting rod is made of steel, one end of the connecting rod penetrates through the upper end plate and is embedded into the upper pier column from the bottom of the upper pier column, the other end of the connecting rod is located on the outer side of the upper pier column, the connecting rod is sleeved with an upper threaded steel sleeve, and an external thread structure is arranged outside the upper threaded steel sleeve; the outer diameter of the upper threaded steel sleeve is slightly smaller than the inner diameter of the lower threaded steel sleeve, the upper threaded steel sleeve is embedded into the lower threaded steel sleeve in a threaded mode, and at the moment, the upper end plate and the lower end plate directly face each other. The bridge pier connecting structure is advantaged in that pier column butt joint difficulty can be reduced, and rapid construction of the fabricated bridge substructure can be achieved.
本发明提供一种基于螺纹连接的桥墩连接结构，包括下墩柱和上墩柱；下墩柱采用混凝土制成，其顶部设置有下端板及连接孔，连接孔贯穿下端板并向下墩柱内部延伸，连接孔内设置有下部螺纹钢套，下部螺纹钢套具有内螺纹结构；上墩柱采用混凝土制成，其底部设置有有上端板和连接杆，连接杆的材质为钢材，其一端贯穿上端板并从上墩柱底部嵌入上墩柱内部，另一端位于上墩柱外侧，连接杆的外部套设有上部螺纹钢套，上部螺纹钢套的外部具有外螺纹结构，上部螺纹钢套的外径略小于下部螺纹钢套的内径，上部螺纹钢套螺纹嵌合下部螺纹钢套，此时，上端板和下端板正对。本发明可以降低墩柱对接难度，并能够实现装配式桥梁下部结构的快速施工。
