description The utility model relates to an adjustable steel box girder storage jig frame with a four-fulcrum supporting and three-fulcrum balancing function. The adjustable steel box girder storage jig frame comprises two adjusting ends and a balance end, each adjusting end comprises a base, a nut and a screw rod in thread fit with the nut are arranged at the upper end of each base, and a first tray used for supporting a steel box girder is arranged at the top end of each screw rod. The balance end comprises a lower frame body and an upper frame body connected with the lower frame body through a self-leveling supporting mechanism, and two second trays are arranged on two sides of the frame body symmetrically. The adjustable steel box girder storage jig frame has the advantages that precision and balance of four fulcrums of the steel box girder are guaranteed; the length of the jig frame can be adjusted so as to adapt to steel box girders of different length specifications; the jig frame can be moved with migration of a
