Anti-deformation supporting structure for rectangular concrete-filled steel tube prefabricated part

The invention belongs to the technical field of buildings, and discloses a rectangular concrete-filled steel tube prefabricated part anti-deformation supporting structure which comprises a base, a bearing plate is fixedly mounted at the top of the base, and outer supporting assemblies are hinged to the four edges of the base correspondingly; by arranging a first transmission ring, a first magnet, a third magnet and the like, the purpose that the rectangular steel pipe prefabricated part is good in supporting effect is achieved, and a transmission rod is driven to rotate by rotating an adjusting ring; the repulsive force of first magnets pushes third magnets, third connecting rods and supporting blocks to move outwards, the outer sides of the supporting blocks make contact with the inner wall of the prefabricated mold, the inner wall of the prefabricated mold is supported, and therefore the exterior of the prefabricated mold is supported, namely the inner wall and the outer wall of the prefabricated mold can b
