摘要（英）：

The utility model discloses a can repair, formula that restores to throne certainly rectangular concrete -filled steel tube frame column base node, include the square steel tube concrete column, prevent bucking steel sheet, base and concrete foundation. Wherein the base includes base and lower base, and lower crab -bolt anchor in concrete foundation for the base goes up base and rectangular concrete -filled steel tube support connnection, be equipped with unbonded prestressed tendons in the rectangular concrete -filled steel tube post, the bucking steel sheet is prevented in being provided with all around of rectangular concrete -filled steel tube post, can be divided into epirelief type column base, three kinds of forms of recessed type column base and spin type column base according to the difference of column base. The utility model has the characteristics of simple structure, construction convenience and easy the restoration, earthquake prevention and disaster reduction can be reached and the function that the back structure restores to the throne is certainly shaken, but wide application in building field.
