Tool type structure construction joint rapid retaining construction method

The invention relates to a tool type structure construction joint rapid reserving construction method. The tool type structure construction joint rapid reserving construction method is applied to the field of concrete construction joint reserving construction. The tool type structure construction joint rapid reserving construction method comprises the following steps that S1, a construction joint reserving position is determined; S2, a reinforcing mesh is bound; S3, after binding of the reinforcing mesh is completed, a steel formwork stopper is installed along a construction joint, the steel formwork stopper is perpendicularly inserted into the reinforcing mesh, and reinforcing steel bars can penetrate through reinforcing steel bar installing notches in the steel formwork stopper; S4, fixing supporting legs on the steel formwork stopper are connected to a floor slab bottom formwork through self-tapping screws, and the steel formwork stopper is fixed; S5, the reinforcing steel bar installing notches are sealed
