Structure of prefabricated combined hollow column

The utility model discloses a prefabricated combined hollow column structure which comprises a middle steel bar structure assembly of a rectangular frame structure, additional steel bar meshes are arranged on the opposite sides of the middle steel bar structure assembly, and a first composite column and a second composite column which are poured later are arranged on the two opposite sides of the middle steel bar structure assembly adjacent to the additional steel bar meshes respectively. The first non-dismantling formwork and the second non-dismantling formwork are poured on the additional reinforcing mesh, and the two ends of the first non-dismantling formwork and the two ends of the second non-dismantling formwork are connected with the two ends of the first composite column and the two ends of the second composite column respectively. The problems that in the prior art, a frame column is heavy in weight, complex in process, high in cost and poor in overall stress performance can be solved. 本实用新型公开了一种预制组合空
