Novel prefabricated assembly type double-layer concrete filled steel tube pier column segment connecting device
The invention discloses a novel prefabricated assembly type double-layer concrete-filled steel tube pier column segment connecting device which comprises an upper prefabricated double-layer concrete-filled steel tube segment, a lower prefabricated double-layer concrete-filled steel tube segment, an energy absorption ring, a prestressed tendon, an energy dissipation shape memory alloy, a reserved bolt and a matched nut. Wherein the prefabricated double-layer concrete-filled steel tube section comprises an outer-layer steel tube, interlayer concrete and an inner-layer steel tube; the energy absorption ring is made of polyurethane foam materials and is filled between the inner steel pipe and the sleeve. The prestressed tendons penetrate through the prefabricated double-layer concrete-filled steel tube sections from the interiors of the inner steel tubes, and the two ends of the prestressed tendons are anchored to a bottom bearing platform and a top cover beam of the pier. The device has the characteristics of high dynamic load resistance, convenience in construction and self-resetting capability.
本发明公开了新型预制装配式双层钢管混凝土墩柱节段连接装置，包括上部预制双层钢管混凝土节段、下部预制双层钢管混凝土节段、吸能环、预应力筋、耗能形状记忆合金、预留螺栓和配套螺母；其中预制双层钢管混凝土节段包括外层钢管、夹层混凝土和内层钢管；所述吸能环为聚氨酯泡沫材料，填充于内钢管与套管之间；所述预应力筋从内钢管内部穿过预制双层钢管混凝土节段，其两端锚固在桥墩底部承台与顶部盖梁。本发明具有抗动载能力强、施工便捷且具有自复位能力的特点。
