The four-side disassembly-free hollow column is formed by wrapping disassembly-free templates outside the reinforcement cage in four sides and adopting a turnover pouring molding process, namely, the reinforcement cage is subjected to three turnover and three pouring of disassembly-free template pouring materials. The structure has the technical problems of small rigidity of the prefabricated column, easy deformation in transportation and hoisting, poor forming precision, four-side dismantling-free template, high manufacturing cost, difficult pre-burying of the wire tube and the wire box, low production efficiency, easy mold expansion in secondary pouring and the like.
