The invention relates to the technical field of steel structure
engineering construction, in particular to a super-long independent steel column segmented locking type temporary stabilizing device and a construction method thereof, and is suitable for the overall lifting stage of a multi-layer aerial corridor. The device comprises a first locking
assembly surrounding a concrete column and providing an X-direction lateral fulcrum; the second locking
assembly is fixedly connected to the surface of the steel column to form a force transmission interface; and the connecting conversion
assembly connects the steel column and the concrete column into a whole, so that the X-direction load of the steel column is transmitted to the concrete column in sections. The super-long
steel columns are temporarily decomposed into short column stress sections with the length not larger than the designed length, and
lateral displacement is remarkably restrained. The construction method comprises the steps that the device is installed at the corridor joint, pre-tightening force is synchronously applied, displacement is monitored in real time, overall dismantling is conducted after lifting is completed, and no residue exists after dismantling. The method is not pre-buried and fully recycled, super-long columns are restored to be in a short column stress state,
lateral displacement is reduced, steel is saved, the construction period is shortened, green construction and appearance completeness are both considered, and the method is suitable for a large-span corridor overall lifting project.
