The utility model discloses a column-inlaid reinforcement bar positioning tool, which comprises four mobile scales and U-shaped blocking points in two forms; the scales are mutually perpendicular and fixed through fixing bolts; the outer sides of the scales are black and white frame bars; the inner sides of the scales are scale marks; the U-shaped blocking points in the two forms are fixed on the four scales through the bolts to realize the accurate positioning of vertical reinforcement bars of a column. According to the column-inlaid bar reinforcement positioning tool, the defects that the reinforcement bars are wasted by normal positioning frames and the use is limited are overcome; the column-inlaid reinforcement bar positioning tool has the advantages that the operation is convenient, the positioning is accurate, the column-inlaid reinforcement bar positioning tool can be used repeatedly, the labor and materials are saved, the reinforcement bars of all rectangular columns can be positioned and the deflection risk of reinforcement bars generated due to collision of workers and machines in the concrete casting process in the traditional positioning method is avoided.
