Abstract
The invention discloses a die for forming uneven reinforcement prefabricated support piles. The die comprises a plurality of circular running wheels arranged along the axial direction of the uneven reinforcement prefabricated support piles to be formed, and uneven reinforcement prefabricated support pile forming cylinders arranged in the circular running wheels; and inner cavities of the uneven reinforcement prefabricated support pile forming cylinders adopt cavities for forming the uneven reinforcement prefabricated support piles. The die is characterized in that the centers of the inner cavities of the uneven reinforcement prefabricated support pile forming cylinders are deviated from the centers of the circular running wheels; and the uneven reinforcement prefabricated support pile forming cylinders are provided with balancing weights with a certain weight, so that through holes of formed pile bodies are deviated from the centers of the pile bodies to achieve the effect of unequal wall thicknesses of the pile bodies. According to the uneven reinforcement prefabricated support piles prepared by the die disclosed by the invention, the flexural capacities of sections can be improved under the condition of the same balanced steel ratio of the sections; and the steel dosage can be reduced when the flexural capacities of the sections are the same.
