Prefabricated steel tube steel reinforced concrete spliced pier column and construction process
The invention discloses a prefabricated steel pipe steel reinforced concrete spliced pier column and a construction technology, and the pier column is divided into a steel end plate-outer bolt connection form, a steel end plate-inner bolt connection form, a reinforcing steel bar outer insertion type splicing form and a reinforcing steel bar inner insertion type splicing form. The upper section and the lower section are spliced and fixed through the steel end plates and the bolt and nut assemblies, when the steel bar external insertion type splicing mode and the steel bar internal insertion type splicing mode are adopted, the upper section and the lower section are internally connected through steel bars and post-pouring concrete, and external connection is achieved through external steel pipe welding. According to the scheme, various joint connection structures are provided, the overall performance of the steel tube steel reinforced concrete spliced pier column can be effectively guaranteed, joint connection is tight, internal force between the upper pier column and the lower pier column can be well transmitted, and the situation that local stress is excessively concentrated to form a dangerous area is avoided; meanwhile, better bearing capacity, ductility, shock resistance, fire resistance and corrosion resistance are achieved.
一种预制钢管型钢混凝土拼接墩柱及施工工艺，墩柱分为钢端板‑外螺栓连接形式、钢端板‑内螺栓连接形式、钢筋外插入式拼接形式及钢筋内插入式拼接形式，采用钢端板‑外螺栓连接形式和钢端板‑内螺栓连接形式时，上下节段之间通过钢端板和螺栓螺母组件进行拼接固定，采用钢筋外插入式拼接形式及钢筋内插入式拼接形式时，上下节段之间通过钢筋和后浇混凝土实现内连接，通过外部钢管焊接实现外连接。本发明的方案中提出了多种节点连接构造，能够有效保证钢管型钢混凝土拼接墩柱的整体性能，节点处连接紧密，能够良好地传递上下墩柱之间的内力，不会造成局部应力过于集中而形成危险区域，同时具备更好的承载力、延性、抗震性、耐火性和耐腐蚀性。
