The invention provides a simple steel pipe bracket for an inner die of a box girder. The simple steel pipe bracket for the inner die of the box girder comprises a lead screw; supporting adjusting seats are arranged at two ends of the lead screw; each supporting adjusting seat comprises a fixing sleeve and a fixing pipe; one end of each fixing sleeve is matched and connected with the lead screw by threads; a circle of convex ring is arranged on the inner wall of the other end of each fixing sleeve; a circle of chute is formed in the outer wall of the end part of each fixing pipe; the convex rings of the fixing sleeves are in match with the chutes. When in use, the fixing sleeves are rotated, the length of the lead screw, exposed from the fixing sleeves can be adjusted, and thus the length of the simple steel pipe bracket for the inner die of the box girder can be adjusted; the mode of individually adjusting the lead screw to reinforce the inner die during mounting the inner die of the traditional box girder at the field can be avoided; the adjusting is convenient and quick; both time and force can be saved; the working efficiency can be increased; the processing cost is reduced; the other end of each fixing pipe is connected with a connecting plate; the connecting plates are connected with jacking devices through rotating shafts; therefore, the simple steel pipe bracket for the inner die of the box girder can cling to an inner die plate of the box girder, and as a result, the force on the inner die plate of the box girder is uniform.
