Swing type self-resetting pier structure provided with belleville springs and construction method
The invention discloses a swing type self-resetting bridge pier structure provided with belleville springs and a construction method, belongs to the field of bridge engineering, and solves the problems of how to improve the anti-seismic property of a bridge and ensure self-resetting of a bridge pier after an earthquake. A bridge pier base is arranged at the bottom of a bridge pier and arranged on a bearing platform, the bridge pier base and the bearing platform are connected through a swing type self-resetting device, the swing type self-resetting device comprises a steel bar and a belleville spring, the steel bar vertically penetrates through the bridge pier base and downwards extends into the bearing platform, and an anchoring end is arranged at the lower end of the steel bar. The anchoring end is located in the bearing platform, a fastening end is arranged at the upper end of the steel bar, and the belleville spring is arranged on the steel bar in a sleeving mode and located between the fastening end and the pier base. The construction method comprises the steps of installing the steel bars, and pouring the bearing platform and the tenons; pre-embedded steel plates are installed; a belleville spring and a fastening end are mounted on the steel bar; and pouring a pier and an upper structure. When the pier swings under the action of an earthquake, the belleville springs are stretched and compressed in a reciprocating manner, and self-resetting force is provided for the pier.
本发明公开了一种配置碟形弹簧的摇摆式自复位桥墩构造及施工方法，属于桥梁工程领域，解决了如何提高桥梁的抗震性能及保证震后桥墩自复位的问题。本发明在桥墩底部设有桥墩基座，桥墩基座设置在承台上，桥墩基座和承台之间通过摇摆式自复位装置连接，摇摆式自复位装置包括钢棒和碟形弹簧，钢棒上下贯穿桥墩基座并向下延伸至承台内部，钢棒下端设有锚固端，锚固端位于承台内部，钢棒上端设有紧固端，碟形弹簧套设在钢棒上且位于紧固端与桥墩基座之间。施工方法：安装钢棒，浇筑承台及凸榫；安装预埋钢板；在钢棒上安装碟形弹簧和紧固端；浇筑桥墩及上部结构。在地震作用下桥墩摇摆，蝶形弹簧将出现往复的拉伸和压缩变形，给桥墩提供自复位力。
