For example, patent CN212469580U discloses a joint positioning mold for processing bridge steel cages, the mold includes a baffle, a base and a fetal membrane cage, the baffle is connected to the fetal membrane cage, the fetal membrane cage includes a reinforcing ring with the same diameter of the steel cage and a main bar with the same diameter of the steel cage; the mold and the bottom of the steel cage to be made are both provided with a base, the base is an arc-shaped groove structure as a whole, a plurality of equally spaced clamps are arranged in the arc-shaped groove structure, horizontal I-shaped support parts are symmetrically arranged on both sides of the bottom of the base, the base is arranged at equal distances in the horizontal direction on the horizontal I-shaped support part, the base is connected to the bottom of the fetal membrane cage where the fetal membrane cage is provided, and the base is connected to the horizontal I-shaped support part where the steel cage is required to be made;

[0004] When in use, the main bars of the same steel cage diameter as the mold are assembled with the main bars of the steel cage to be made, so as to determine the positions of the main bars of the standard section, and then the reinforcing hoops are welded to the main bars to complete the production of the standard section. However, in practice, the pile diameters on the construction site are different, and the above-mentioned positioning mold can only be used to produce standard sections for one pile diameter. In order to meet the production of standard sections with different pile diameters, multiple positioning molds need to be prepared, which takes up more space on the construction site and is extremely confusing to manage.
