Counter-jacking repairing scheme for loaded offset concrete filled steel tube column
The invention discloses a counter-jacking repairing scheme for a loaded offset concrete filled steel tube column and relates to the field of building repairing. The counter-jacking repairing scheme for the loaded offset concrete filled steel tube column includes steps that (1) analyzing to confirm pre-loading counterforce and loading stages; (2) preparing for repairing; (3) applying jacking pre-stress stage by stage; (4) removing an original steel column; (5) mounting a new steel column; (6) detecting the repaired steel column; (7) removing the pre-stress stage by stage to remove temporary supports; (8) repeating the steps 3 to 7 to repair the other steel columns. After the temporary supports in the counter-jacking repairing scheme for the loaded offset concrete filled steel tube column apply pre-stress, the original steel column bears very small axial force, in the controllable range, the analysis proves that the construction stress change can be ignored, the maximum displacement change amount is 0.28 millimeters before and after construction, and therefore, the displacement change amount can be ignored; the stress and displacement change in the steel column change process and before and after change can be ignored, and the whole counter-jacking repairing process is safe and reliable.
