The invention provides a steel box girder splicing temporary alignment fixing device, and relates to the field of alignment tools, the steel box girder splicing temporary alignment fixing device comprises moving parts, the moving parts are of rectangular structures, the inner side of each moving part is provided with a sliding groove, the sliding grooves are of T-shaped structures, the bottom of the outer end of each moving part is provided with a fixing part, the fixing parts are of U-shaped structures, and the fixing parts are made of metal materials; the upper side and the lower side in the outer end of each fixing piece are of an inclined structure. After the two steel box girders are aligned and butted, large friction force can be generated at the contact position, in the trimming and adjusting process of the moving part, the pushing part makes the outer end of the pushing part make contact with the multiple stress blocks through the elasticity of the pushing part, the pushing part is jacked by the multi
