Summary: | A newly-built foundation upper column and lower column connecting structure for expanding an underground space comprises an upper structure column (1) and a newly-built basement steel pipe concrete column (2) which are oppositely arranged, and four steel plates (3) connected end to end are pre-buried in the periphery of the lower portion of the upper structure column (1) and the periphery of the upper portion of the newly-built basement steel pipe concrete column (2). A high-strength inorganic grouting material (4) is poured into a space defined by the four steel plates (3), and the basement steel pipe concrete column (2) and the four steel plates (3) are welded into a whole. And implementation is convenient, and reliable connection force transmission between the upper column and the lowercolumn can be ensured.
一种用于扩展地下空间的新建基础上下柱连接结构,包括相对设置的上部结构柱(1)和新增的地下室钢管混凝土柱(2),所述上部结构柱(1)下部和新增的地下室钢管混凝土柱(2)上部四周预埋有首尾相接的四块钢板(3),该四块钢板(3)围成的空间内部浇筑有高强无机灌浆料(4),且地下室钢管混凝土柱(2)与四块钢板(3)焊接成整体。既便于实施,也能保证上下柱之间的连接传力可靠。 |
