Embedded flange for steel column-concrete foundation, connecting structure and construction method
The invention discloses an embedded flange for a steel column-concrete foundation, a connecting structure and a construction method.The embedded flange comprises an embedded steel plate flange body and a plurality of PBL perforated stiffening plates, the PBL perforated stiffening plates are evenly arranged in the circumferential direction of the embedded steel plate flange body and perpendicularly welded to the lower surface of the embedded steel plate flange body, and the PBL perforated stiffening plates are evenly arranged in the circumferential direction of the embedded steel plate flange body; the weld strength of the pre-embedded steel plate flange and the PBL perforated stiffening plate is higher than the strength of a base material, and a hole is formed in the middle of the pre-embedded steel plate flange; the whole embedded steel plate flange is rectangular or circular; a hole is formed in the center of the pre-embedded steel plate flange and is the same as the pre-embedded steel plate flange in shape; the construction speed is high, the assembly degree is high, the stress transition of a foundation connecting structure formed by the steel flange bearing plate and the PBL shear keys is smoother, the shearing force transmission efficiency is higher than that of the three traditional pier column connecting methods, the shearing resistance and the earthquake resistance are better, a connecting face is created for steel column-concrete foundation connection, and the construction period is shortened. The method cannot be realized in the three traditional connection methods of the assembled pier column and the foundation.
本发明公开了一种钢柱‑混凝土基础用预埋法兰、连接结构及施工方法，包括预埋钢板法兰和多个PBL开孔加劲板，PBL开孔加劲板沿预埋钢板法兰周向均匀布置，PBL开孔加劲板垂直焊接在预埋钢板法兰的下表面，预埋钢板法兰和PBL开孔加劲板的焊缝强度高于母材强度，预埋钢板法兰中部开孔；预埋钢板法兰整体为矩形或圆形；预埋钢板法兰中心开孔，开孔形状与预埋钢板法兰形状相同；施工速度快，装配化程度高，钢法兰承压板与PBL剪力键形成的基础连接结构其应力过渡更为平缓，剪力传递效率较以上三种传统墩柱连接方法更高，其抗剪抗震性能更优，为钢柱‑混凝土基础连接创造连接面，是传统的装配化墩柱与基础的连接三大方法中不能实现的。
