Utility model content
In order to overcome prior art not enough, this utility model provides a kind of square steel tube concrete column with function of seismic resistance, purpose is the structure by improving steel core concrete column upper/lower terminal, improve the shock resistance of steel core concrete column upper/lower terminal, thus improving the mechanical property of whole steel core concrete column.
Technical solution of the present utility model: a kind of square steel tube concrete column with function of seismic resistance, including outer layer pipe and be filled in the concrete within outer layer pipe, it is characterized in that: be additionally provided with inner layer steel pipe in the inside of outer layer pipe, described inner layer steel pipe lays respectively at the upper/lower terminal of outer layer pipe, the inwall uniform welding of inner layer steel pipe has some reinforcing bars, is connected by ribbed stiffener between described inner layer steel pipe and outer layer pipe.
The bottom of preferred described outer layer pipe is additionally provided with bearing.
The height of the inner layer steel pipe being preferably located at outer layer pipe upper/lower terminal is identical, and equal to the length of reinforcing bar.
The height of the inner layer steel pipe being preferably located at outer layer pipe upper/lower terminal all accounts for the 1/6 ~ 1/7 of outer layer pipe total height.
Distance between inwall and the outer wall of inner layer steel pipe of preferred described outer layer pipe is the 1/4 of two opposite face inner distance of outer layer pipe.
Preferred described ribbed stiffener is evenly arranged with several through holes.
The inwall of preferred described inner layer steel pipe is evenly arranged with several through holes.
The junction of preferred described ribbed stiffener and outer layer pipe and inner layer steel pipe is provided with reinforcement.
