Connecting joint between top-down concrete-filled steel tubular column and bottom-up steel tubular column
The invention relates to a connecting joint between a top-down concrete-filled steel tubular column and a bottom-up steel tubular column, and belongs to the field of foundation pit engineering. According to the technical scheme, the bottom-up steel tubular column penetrates through a basement roof to the upper part of the top-down concrete-filled steel tubular column; the section of the bottom-upsteel tubular column is larger than that of the top-down concrete-filled steel tubular column; a ring plate is welded to the top surface of the top-down concrete-filled steel tubular column; a transition column section with big-end-up variable section is arranged at the bottom of the bottom-up steel tubular column, the upper section size of the transition column section is the same as that of thebottom-up steel tubular column, the lower section size of the transition column section is the same as that of the top-down concrete-filled steel tubular column, and the wall thickness is same as thatof the bottom-up steel tubular column; and a filling section is arranged above the position of the bottom-up steel tubular column protruding the basement roof, the transition column section and the local bottom-up steel tubular column are filled with self-compacting micro-expansive concrete, the filling bottom elevation is the bottom surface of the transition column section, and the filling top elevation is the top surface of the filling section. By using the joint, the problem of force transfer between the bottom-up steel tubular column on the upper part and the top-down concrete-filled steel tubular column on the lower part is solved completely.
本发明属于基坑工程领域的一种逆作钢管混凝土柱与顺作钢管柱连接节点，技术方案为：顺作钢管柱穿过地下室顶板至逆作钢管混凝土柱的上部；顺作钢管柱的截面大于逆作钢管混凝土柱截面；逆作钢管混凝土柱顶面焊接环板；顺作钢管柱的底部设置上大下小变截面过渡柱段，过渡柱段的上截面尺寸与顺作钢管柱相同，下截面尺寸与逆作钢管混凝土柱相同，壁厚同顺作钢管柱；顺作钢管柱出地下室顶板以上设有填充段，自密实微膨胀混凝土填充过渡柱段和局部顺作钢管柱，填充底标高为过渡柱段的底面，填充顶标高为填充段的顶面。采用该节点，完全解决了上部的顺作钢管柱与下部的逆作钢管混凝土柱的传力问题。
