Construction method for reinforcing structure for steel column formworks

The invention discloses a construction method of a reinforcing structure for steel column formworks. Specific to the situation that traditional large-cross-section column formworks adopt a reinforcing method of steel pipes, buckling pieces or built-in opposite-pulling rods, so that the problem of the phenomena of column concrete formwork swelling, deviation of the cross-section size, unevenness of the surface, mortar leakage and the like is liable to occur, the construction method comprises the following steps that 1, the steel column formworks are assembled according to the size of a column; 2, the steel column formworks are hoisted to the position of the column and mounted; and 3, a plurality of channel steel embracing hoops are mounted at intervals along the longitudinal direction of the steel column formworks around the steel column formworks, and the channel steel embracing hoops are fixed through opposite-pulling bolts of the outer side of the column. According to the construction method of the reinforc
