Steel column bottom cross-shaped steel integrated anti-punching column base joint and construction method
The invention relates to a steel column bottom cross-shaped steel integrated anti-punching column base joint and a construction method. The column base joint comprises a steel column and a column base foundation, and the steel column is fixedly connected to the column base foundation through a base plate and an embedded anchor bolt. Cross-shaped steel and an anchoring bottom plate are embedded in the column foot foundation, and the cross-shaped steel is formed by splicing and welding first-direction H-shaped steel and second-direction H-shaped steel. The anchoring bottom plate is pre-buried in the column foot foundation; one or more lengthened studs are welded to the portion, located below the base plate, of the upper flange plate of the first-direction H-shaped steel and/or the second-direction H-shaped steel, anchoring holes are correspondingly formed in the base plate, the lengthened studs stretch into the anchoring holes, and high-strength grouting materials are poured into the anchoring holes. Through the integrated design of the column bottom profile steel, the joint connection strength and the punching resistance of the column foot can be improved, the construction difficulty is reduced, the construction time is greatly shortened, the installation and construction efficiency is improved, the construction period is effectively shortened, and the labor cost is reduced.
本发明涉及一种钢柱柱底十字型钢一体化抗冲切柱脚节点及施工方法。柱脚节点包括钢柱和柱脚基础，钢柱通过垫板和预埋锚栓连接固定于柱脚基础上；柱脚基础内预埋有十字型钢和锚固底板，其中十字型钢由第一方向H型钢和第二方向H型钢拼接焊接形成；锚固底板预埋于柱脚基础内；并且第一方向H型钢和/或第二方向H型钢的上翼缘板上位于垫板下方焊接有一根或多根加长栓钉，垫板上对应开设有锚固孔，加长栓钉伸入锚固孔内并在锚固孔内灌注有高强灌浆料。本发明通过柱底型钢一体化的设计可以提高节点连接强度和柱脚抗冲切能力，降低施工难度，极大的缩短施工时间，提高安装施工效率，有效节约工期并减少人力成本。
