The invention relates to the field of building structure moulds, solves the problems that after a building template is installed, gaps are liable to generate so as to cause grout leakage, so that voids and pits are generated on concrete, and therefore, the quality of the concrete is affected, and provides a columnar frame structure mould. The columnar frame structure mould comprises four frames, sealing strips and first tensioning structures, wherein the four frames are arranged from head to tail in sequence to form a columnar structure with a hollow accommodating cavity; each sealing strip correspond to the connecting seam of every two adjacent frames; the two connecting portions of each first tensioning structure are respectively connected with the two adjacent frames, and the first tensioning structures are used for tensioning the two adjacent frames, so that the two sealing portions of each sealing strip squeeze the two adjacent frames, and the connecting seams are isolated from the accommodating cavity. The columnar frame structure mould provided by the invention has the beneficial effects that the two adjacent frames are tensioned by the first tensioning structures, so that the sealing portions of the sealing strips closely fit the inner side walls of the two frames, the concrete in the accommodating cavity is prevented from being discharged from the connecting seams, andthe effect of preventing the grout leakage is realized.
