Reverse inverted-insertion type construction method for structural steel columns
The invention belongs to the technical field of reverse construction, and provides a reverse inverted-insertion type construction method for structural steel columns. The purpose is to solve the technical problems that in reverse construction, when temporary supporting columns are replaced, the construction process is complex, construction difficulty is high, the construction period is long, waste is generated after disassembling, and the construction cost is increased. The construction method includes the steps that the position deviation and the perpendicularity deviation of the steel pipe temporary supporting columns are measured accurately, accurate setting-out is performed according to calculated data, and after the cross-welded steel columns, the T-type steel columns and a column bottom plate are manufactured, inverted-insertion type installing of the upper cross-welded steel columns, installing of the lower T-type steel columns and installing of the column bottom plate and foundation bolts are performed. Compared with temporary supporting column replacing construction, the method is simple and rapid to implement, lowers the construction difficulty and shortens the construction period, and time can be reduced by 0.5d when each structural steel column is constructed; in addition, labor, materials and equipment needed to be input in replacing disassembling of the temporary supporting columns are reduced, the waste generated by disassembling is reduced, and the construction cost is lowered.
