Mortise and tenon joint type connecting structure of prefabricated concrete-filled steel tube pier and splicing method of mortise and tenon joint type connecting structure
The invention relates to the technical field of highway bridge construction engineering, and discloses a mortise and tenon joint type connecting structure of a prefabricated concrete-filled steel tube pier and a splicing method of the mortise and tenon joint type connecting structure. The connecting structure comprises a prefabricated steel pipe pier, a bearing platform, an anchor rod and concrete, a bearing plate is welded at the bottom of the prefabricated steel pipe pier and is anchored with the bearing platform through an anchor rod; concrete is poured in the prefabricated steel pipe pier, an inwards-concave area is arranged in the center of the bearing platform, and the lower section of the concrete in the prefabricated steel pipe pier extends out to the inwards-concave area of the bearing platform to form a mortise and tenon joint structure. The connecting structure and construction are convenient and fast, the construction period of the concrete filled steel tube pier is shortened, the construction cost of manpower and time is reduced, the anti-seismic property and energy dissipation capacity of the pier under the earthquake action can be improved, the pier has the capacity of rapidly recovering traffic after the earthquake, and the fabricated concrete filled steel tube pier can be widely popularized.
本发明涉及公路桥梁建设工程技术领域，公开了一种预制钢管混凝土墩的榫卯式连接构造及其拼接方法。连接构造包括预制钢管墩、承台，还包括锚杆、混凝土；所述预制钢管墩底部焊接承压板，通过锚杆与承台锚固；所述预制钢管墩内浇筑有混凝土，所述承台中央设有内凹区域，预制钢管墩内混凝土下段外伸至承台内凹区域，形成榫卯结构。本发明连接构造及施工便捷，缩短了钢管混凝土桥墩的施工周期，减少人工与时间的建设成本，并且能够提高桥墩在地震作用下的抗震性能、耗能能力，使桥墩在震后具有快速恢复交通的能力，使装配式钢管混凝土墩得以广泛推广。
