The utility model discloses a steel tube holding frame, which comprises two groups of brackets, wherein the two groups of brackets are fixed together through connecting rods; each bracket consists of bottom support rods, support columns and isolating rods; the support columns and vertical columns are welded in sequence at the two ends and on the middle parts of each bottom support rod; oblique triangular brackets are fixed on the left and right sides of the upper end of each vertical column; the same triangular bracket is fixed at the upper end of each support column on one side of each vertical column; a plurality of isolating rods are uniformly distributed between the vertical columns and the support columns; the isolating rods include first isolating rods and second isolating rods; the first isolating rods and the second isolating rods are fixed on the bottom support rods alternately. According to the steel tube holding frame, steel tubes are managed in a classified way by using the isolating rods in the holding frame, so that ordered arrangement of the steel tubes is realized, and the requirement of safe and civilized construction standardization is met; meanwhile, accidents such as crashing hurt caused by the steel tubes are reduced.
