Column foot joint of civil air defense project entrance and exit steel structure anti-collapse shed frame
The invention belongs to the field of civil air defense building engineering, and discloses a column foot joint of a civil air defense project entrance and exit steel structure anti-collapse shed frame. According to the technical scheme, a civil air defense project entrance and exit channel is located on the ground-out section of an outdoor entrance and exit channel, and a concrete outer wall is arranged at the ground-out position of the civil air defense project entrance and exit channel; the section size of a steel column of the steel structure anti-collapse shed frame is larger than the thickness of the concrete outer wall, and studs are arranged on the periphery of a column root; the column root is welded to the lower portion of the steel column to form a whole; a bracket is arranged on the top side face of the concrete outer wall, and a cup opening is reserved in the bracket; and the column root is inserted into the cup opening, and the cup opening is filled with micro-expansion concrete. Or a non-cup-opening bracket is arranged on the top side face of the concrete outer wall; studs are arranged on the periphery of the column root; the lower portion of the column root is pre-buried in the non-cup-opening bracket to be poured into an integral component; and the steel column and the column root are welded. By means of the column foot joint, the firmness of rigid connection between the steel column and the concrete is achieved, meanwhile, the size of the concrete bracket is optimized, and the connection problem generated when the size of the steel column is larger than that of the lower concrete outer wall is solved.
本发明属于人防建筑工程领域的人防工程出入口钢结构防倒塌棚架的柱脚节点。技术方案为：人防工程出入口通道位于室外出入口通道的出地面段，人防工程出入口通道的出地面处设置混凝土外墙；钢结构防倒塌棚架的钢柱截面尺寸大于混凝土外墙的厚度，柱根外周设有栓钉；钢柱下焊接柱根形成整体；混凝土外墙顶侧面处设置牛腿，牛腿内预留杯口；柱根插入杯口内，并在杯口内填充微膨胀混凝土。或者混凝土外墙顶侧面处设置无杯口牛腿；柱根外周设有栓钉；柱根的下部预埋入无杯口牛腿内浇筑成整体构件；钢柱与柱根焊接。其解决了钢柱与混凝土刚性连接的牢固性，同时优化了混凝土牛腿的尺寸，解决了当钢柱尺寸大于下部混凝土外墙时的连接问题。
