Variable cross-section circular pipe forked column and construction method thereof
The invention provides a variable cross-section circular tube bifurcated column, which relates to the technical field of constructional engineering, and comprises a bottom concrete layer, a column foot ring plate, a steel column and a column foot bolt pre-buried in the bottom concrete layer, the upper end of the column foot bolt is detachably connected to the column foot ring plate, a grouting material layer is arranged between the column foot ring plate and the bottom concrete layer, the steel column comprises a V-shaped supporting column and a circular pipe column, the V-shaped supporting column and the circular pipe column are integrally formed, the lower end of the circular pipe column is coaxially and fixedly connected to the column foot ring plate, and an outer wrapped concrete layer is arranged on the periphery of the circular pipe column. A plurality of column steel bars are arranged in the bottom concrete layer, open holes are formed in the column foot annular plate, the upper ends of the column steel bars penetrate through the open holes and extend into the tubular column, and annular stirrups for fixedly connecting the column steel bars are arranged at the upper ends of the column steel bars. The invention further provides a construction method of the variable cross-section circular pipe bifurcated column. The problem that in the prior art, the reliability of connection between a steel column and a concrete structure needs to be improved is solved.
本发明提供了一种变截面圆管分叉柱，涉及建筑工程技术领域，包括底部混凝土层、柱脚环板、钢柱和预埋在底部混凝土层内的柱脚螺栓；所述柱脚螺栓上端可拆卸连接在柱脚环板上，所述柱脚环板与底部混凝土层之间设有灌浆料层，钢柱包括V形支撑柱和圆管柱，V形支撑柱和圆管柱一体成型，所述圆管柱下端同轴固接在柱脚环板上，所述圆管柱外周设有外包混凝土层；所述底部混凝土层内设有若干柱钢筋，所述柱脚环板上设有开孔，所述柱钢筋上端穿过所述开孔并伸入所述圆管柱内，若干所述柱钢筋上端设有将若干所述柱钢筋固接的环形箍筋。还包括一种变截面圆管分叉柱的施工方法。其解决了现有技术中存在的需要提高钢柱与混凝土结构连接的可靠性的问题。
