Background
The steel pipe concrete is a member formed by combining a steel pipe and filled concrete, has the advantages of high bearing capacity, high rigidity, good earthquake resistance and fire resistance and the like, and has a great amount of application in high-rise and super high-rise buildings in China as a vertical bearing member. When the steel pipe concrete column is connected with a foundation, because the column steel pipe is a closed section, when traditional bolt connection column feet are adopted, because traditional bolts can be installed only by double-sided operation, constructors possibly need to enter the steel pipe for internal operation, so that the construction convenience is influenced, and potential safety hazards are caused to the constructors. If the field welding type column base is adopted, necessary welding process and quality need to be met, the welding technical requirement on constructors is high, and the reliability of the connection between the concrete-filled steel tubular column and a foundation is possibly influenced. Therefore, a novel steel tube concrete column base connection method needs to be provided to meet the requirements of convenience in site construction, reliable connection performance, good integrity and seismic performance and the like.
SUMMERY OF THE UTILITY MODEL

A connecting steel pipe (6) with the outer side length (outer diameter) slightly larger than the outer side length (outer diameter) of the column steel pipe (1) is welded on the flange plate (3), single-layer or multi-layer unilateral bolt holes are reserved in one side of the connecting steel pipe (6) and the column steel pipe (1), the unilateral bolts sequentially pass through the connecting steel pipe (6) and the column steel pipe (1), and the connecting steel pipe (6) is connected with the column steel pipe (1).
The section of the steel pipe is square or round.
The cross section of the connecting steel pipe is square or round.
The utility model has the advantages that:
1. this kind of column foot is connected and is passed the power route clear and definite, can effectually transmit the basis with post axial force, moment of flexure and shear force, and unilateral bolt convenient operation, dependable performance, constructor need not to work in the narrow and small steel pipe inside in space, has ensured construction progress and personnel safety.
2. The node does not need or only needs little welding workload of a factory, only needs to reserve bolt holes on the steel pipe and the connecting steel pipe, is convenient to process, and avoids the influence of welding residual stress and welding seam quality caused by field welding.
