Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a combined steel tube concrete pillar. Background Art

[0002] CFST usually refers to concrete filled in steel tubes. The compressive bearing capacity of CFST components is generally higher than the sum of the bearing capacities of the steel tubes and core concrete that make up the CFST. The compressive bearing capacity of this structure is usually higher than the sum of the bearing capacities of steel tubes or concrete alone. Through this combination, components such as CFST pillars can share the load more effectively when subjected to external pressure, improving the strength and stability of the overall structure.

[0003] In current engineering use, the method of fixing concrete pillars is to bury part of them in a reserved pit and then fill the pit. After long-term use, this method will cause the loose soil to make the concrete pillars unstable, and they will shake or even fall or collapse. Therefore, a combined steel tube concrete pillar is proposed to solve the above problem. Utility Model Content
