Earthquake damage replaceable combination column structure
The invention discloses an earthquake damage replaceable combination column structure which comprises a core square steel pipe, a ground beam end plate and four replaceable steel boxes. The core square steel pipe is arranged on the ground beam end plate, the lower end of the core square steel pipe is closed, the upper end of the core square steel pipe is fixedly connected with an RC column through a plurality of first fixedly connecting structures and provided with an opening containing the lower end of the RC column, the ground beam end plate is fixedly arranged on a ground beam through second fixedly connecting structures, and the four replaceable steel boxes are detachably arranged on walls of the core square steel pipe respectively to surround the core square steel pipe. After an earthquake, only the peripheral replaceable steel boxes can be subjected to buckling failure, the core square steel pipe is only slightly destructed or not destructed, controllability of a destruction position is realized on the premise of ensuring vertical bearing capacity, earthquake resistance is excellent, the column is reset after the earthquake, the replaceable steel boxes are detached and replaced by intact steel boxes, and the structure is rapidly repaired after the earthquake.
