Fabricated integrated pier column and bent cap combined structure and construction method thereof
The invention discloses a fabricated integrated pier column and bent cap combined structure and a construction method thereof. The combined structure comprises a steel bent cap and a steel-concrete combined pier column. According to the steel-concrete combined pier column, connection and load transmission between a steel pipe column and filled concrete and between the steel pipe column and foundation concrete are achieved through vertical stiffening plates and perforated annular steel bars. The combination technology has the advantages of being high in bearing capacity, short in combination section and easy and convenient to manufacture, micro-expansion concrete is poured into the steel pipe to form the combined section, and the advantages of being high in bearing capacity, large in horizontal rigidity, high in impact resistance, capable of saving manufacturing cost and the like are achieved. The steel bent cap is of a box-type lattice structure and is directly anchored to the supporting core tube section of the pier column, the overall structure is simple, the force transmission path is clear, and the fabricated integrated pier column and bent cap combined structure and the construction method thereof are suitable for a single-pile structure, and are suitable for a multi-column structure and high in universality.
本发明公开了一种装配式一体化墩柱盖梁组合结构及其施工方法，组合结构包括钢盖梁和钢混组合墩柱，其中钢混组合墩柱通过“竖向劲板+穿孔环形钢筋”复合式剪力连接件来实现钢管柱与填充混凝土、基础混凝土的连接和荷载传递，实现共同受力，该结合技术具有承载力高，结合段短，制造简便的优势，钢管内灌注微膨胀混凝土形成组合截面，具有承载能力高，水平刚度大，抗撞击能力强、造价省等优势；钢盖梁采用箱型格构式构造，直接锚固于墩柱的支撑核心筒节段上，整体构造简洁，传力路径清晰，不仅适用于单桩式结构，也适用于多柱式，通用性强。
