Fabricated swing bridge pier with built-in energy consumption device and prefabrication and assembly method of fabricated swing bridge pier
A hollow pier body of the pier is divided into a pier bottom section, a pier top section and a plurality of prefabricated standard sections between the pier bottom section and the pier top section, when the standard sections are prefabricated, buckling-restrained energy dissipation devices in the height direction of the standard sections are fixed in an inner cavity, and when the pier top section is prefabricated, a mounting base is fixed in the inner cavity; unbonded prestressed steel bars are anchored in the axial center of the pier bottom section and the cast-in-place concrete foundation, and rod type dampers are hinged to the two transverse sides; the pier bottom section and the standard section are positioned and assembled through joint bars, and the rod type damper is hinged to an energy dissipation component of the buckling-restrained energy dissipation device through a steel connecting rod. The adjacent standard sections are positioned and assembled through joint bars, and the upper energy dissipation component and the lower energy dissipation component are hinged through steel connecting rods. The standard section and the pier top section are positioned and assembled through joint bars, and an energy dissipation component of the buckling-restrained energy dissipation device is hinged to a mounting base on the inner wall of the pier top section through a steel connecting rod. The bridge pier has the advantages of being rapid in site construction, good in bridge pier integrity, high in lateral stiffness and remarkable in damping effect.
本发明公开了一种内置耗能装置的装配式摇摆桥墩及其预制和装配方法，桥墩的空心墩体分为墩底段、墩顶段和它们之间的多节标准段预制，标准段预制时内腔固定沿其高度方向的防屈曲耗能装置，墩顶段预制时在内腔固定安装座；墩底段与现浇混凝土基础的轴向中心锚固无粘结预应力钢筋，横向两侧铰接杆式阻尼器；墩底段与标准段通过插筋定位装配，杆式阻尼器通过钢制连杆与防屈曲耗能装置的耗能构件铰接；相邻标准段通过插筋定位装配，上、下耗能构件之间通过钢制连杆铰接；标准段与墩顶段通过插筋定位装配，防屈曲耗能装置的耗能构件通过钢制连杆与墩顶段内壁的安装座铰接。具有现场施工快捷、桥墩整体性好、抗侧刚度强、减震效果显著的优势。
