Die holder for assembling steel reinforcement cage of prefabricated box girder

The utility model provides a die holder for assembling the steel reinforcement cage of a prefabricated box girder, which comprises two longitudinal bases. A plurality of transverse bases are fixedly arranged on the longitudinal bases. The two sides of each transverse base are respectively and symmetrically provided with an outwards inclined cant beam. Each cant beam is vertically provided with a plurality of transverse bushings. A steel pipe capable of sliding along the bushing is arranged in each transverse bushing. Each transverse base is longitudinally provided with at least two bottom beams and each cant beam is provided with a central beam. The upper ends of the bottom beams and the central beams are provided with a plurality of notches. According to the utility model, the colligation and combination of a steel reinforcement cage realized through the die holder is simple and convenient in operation and is integrally unified so as to be consistent with the same standard. The die holder can be installed on
