Anti-seismic arch bridge structure
The invention discloses an anti-seismic arch bridge structure, and belongs to the technical field of bridge structures, the anti-seismic arch bridge structure comprises a bridge body and bridge abutments connected with two ends of the bridge body, the bridge abutments are provided with cavities for accommodating the ends of the bridge body, the cavities are obliquely arranged, the bottoms of the cavities are provided with a plurality of guide rails parallel to the cavities, the guide rails are slidably connected with supporting columns, and the supporting columns are connected with the bridge body. Buffering energy consumption devices are arranged between the supporting columns and the bridge abutment. The bridge body comprises a plurality of sections of arc-shaped bridge plates, arc-shaped grooves are formed in the opposite ends of the bridge plates, connecting plates are connected into the arc-shaped grooves in a sliding mode, assembling shafts are arranged between the adjacent bridge plates, the connecting plates are detachably connected with the assembling shafts, and elastic reset devices are arranged between the connecting plates and the arc-shaped grooves. The bridge plates located at the ends are connected with the corresponding supporting columns. The technical problem that an existing arch bridge structure is not beneficial to seismic resistance is solved.
本发明公开了一种抗震型拱桥结构，属于桥梁结构技术领域，包括桥体、与桥体两端连接的桥台，所述桥台上设置有容纳与桥体端部的空腔，所述空腔倾斜设置，所述空腔底部设置有若干与空腔平行的导轨，所述导轨上均滑动连接有支撑柱，所述支撑柱与桥台之间设置有缓冲耗能装置；所述桥体包括若干节弧形的桥板，桥板之间的相向端上均开设有弧形槽，弧形槽内滑动连接有连接板，相邻桥板之间设置有装配轴，所述连接板与装配轴可拆卸连接，所述连接板与弧形槽之间设置有弹性复位装置；位于端部的桥板则与对应的支撑柱连接；本发明的目的在于解决现有的拱桥结构不利于抗震的技术问题。
