Column foot structure of story-adding steel column of existing prestressed structure
The invention provides a column foot structure of a story-adding steel column of an existing prestressed structure. The column foot structure is applied to a story-adding reconstruction project at the upper part of a concrete structure of an existing prestressed building and is a story-adding steel column connecting structure at a tensioning end of a prestressed beam-column joint, the column foot structure comprises a rectangular steel pipe column, outer wrapping column base-longitudinal steel bars, outer wrapping column base-stirrups, steel column transverse partition plates, stiffening connecting plates, shoe beam-transverse plates, shoe beam-positioning anchor bolts, shoe beam-webs, shoe beam-rib plates, steel column bottom plates, steel bar meshes, column side tensioning sections, column base-transverse plates, column base-positioning anchor bolts, buckling-restrained steel plates, base plates, foundation anchoring ribs, shoe beam-side plates, additional anchoring ribs, hanging ribs and the like. According to the column foot structure, the height of the outer wrapping column base can be reduced, prestressed components and stress ribs of a built structure are prevented from being damaged, meanwhile, cooperative stress with the foundation is achieved, the overall rigidity and anti-seismic performance of the joint are improved, the design principle that structural components are connected with weak components in a strong mode is achieved, the structure is simple, and prefabricated component construction is facilitated.
本发明提供一种既有预应力结构加层钢柱柱脚结构，应用于既有预应力建筑混凝土结构上部加层改造工程中，预应力梁柱节点张拉端加层钢柱连接结构，包括：矩形钢管柱、外包柱脚‑纵向钢筋、外包柱脚‑箍筋、钢柱横向隔板、加劲连接板、靴梁‑横板、靴梁‑定位锚栓、靴梁‑腹板、靴梁‑肋板、钢柱底板、钢筋网、柱侧张拉段、柱脚‑横板、柱脚‑定位锚栓、防屈曲钢板、垫板、基础锚固筋、靴梁‑侧板、附加锚固筋、吊筋等。本发明不仅可以降低外包柱脚高度，避免破坏已建结构的预应力构件及受力筋，且同时与基础协同受力提高节点整体刚度、抗震性能，实现结构构件强连接弱构件的设计原则，构造简单，便于预制构件施工。
