Energy consumption type segment prefabricated and assembled double-layer concrete-filled steel tube combined pier column
The invention discloses an energy consumption type section prefabricated and assembled double-layer concrete-filled steel tube combined pier column which comprises double-layer concrete-filled steel tube prefabricated sections, internal prestressed tendons and outer side energy consumption connecting parts. Each double-layer concrete-filled steel tube prefabricated section comprises an outer steel tube with a plurality of trapezoidal notches, high-strength non-shrinkage concrete and an inner steel tube; the inner prestressed tendons penetrate through the double-layer concrete-filled steel tube prefabricated sections needing to be connected from the center of the inner steel tube, the outer side energy dissipation connecting component comprises energy dissipation soft steel dampers, cover plates and ECC filling materials, the energy dissipation soft steel dampers are inserted into hourglass-shaped notches between the adjacent sections, the cover plates cover the hourglass-shaped notches, and the ECC filling materials are arranged in the hourglass-shaped notches. ECC filling materials are injected into the cover plate through the grouting openings, and effective connection between joints of the double-layer concrete-filled steel tube prefabricated sections is formed. The bridge pier has the characteristics of outstanding dynamic load resistance and rapid construction, and is particularly suitable for popularization and application of the bridge pier in a high-intensity earthquake area.
本发明公开了一种耗能型节段预制拼装双层钢管混凝土组合墩柱，包括双层钢管混凝土预制节段、内部预应力筋和外侧耗能连接部件；所述双层钢管混凝土预制节段包括设有若干个有梯形槽口的外钢管、高强度无收缩混凝土和内钢管；所述内部预应力筋从内钢管中心穿过所需连接的双层钢管混凝土预制节段，所述外侧耗能连接部件包括耗能软钢阻尼器、盖板和ECC填充材料，所述耗能软钢阻尼器插入相邻节段之间的沙漏形槽口，所述盖板覆盖于沙漏形槽口，所述盖板通过注浆口注入ECC填充材料，形成双层钢管混凝土预制节段接缝之间的有效连接。本发明具有抗动力荷载性能突出和快速施工的特点，特别适合于高烈度地震区该类桥墩的推广应用。
