The utility model provides a slope surface pipe column frame bent base. The slope surface pipe column frame bent base comprises connecting frames and supporting bases, wherein the plurality of supporting bases are fixed on the two parallel connecting frames; connecting plates are fixed at two ends of the connecting frames; and a plurality of connecting frame holes are formed in the connecting frames. The supporting bases comprise upper surfaces, which are parallel to a horizontal plane, and supporting frames, which are vertical to the horizontal plane; the upper surfaces are fixedly connected with the supporting frames; and bolt holes are formed in the upper surfaces. After the slope surface pipe column frame bent base device provided by the utility model is connected with pipe columns by bolts, the a plurality of pipe columns are integrally connected, so that the integrity and stability of the pipe column frame bent are enhanced, contribution is made to saving construction materials, engineering cost is saved and construction progress is accelerated. The slope surface pipe column frame bent base device provided by the utility model is simple, fast and convenient to mount and demount and can be used in a repetitive way.
