The utility model belongs to the technical field of the construction of pier reinforcing bar, specifically a pier vertical reinforcement installation mould. The problem of pier construction vertical reinforcement in heavy handled vertical reinforcement interval of ligature in -process and perpendicularity is solved, a pier vertical reinforcement installation mould, frame connection spare and mould skeleton including frame rack structure, the inboard welded connection of frame connection spare has the mould skeleton, even welding has a plurality of rebar positioning teeth on the mould skeleton, the card has the pier shaft vertical reinforcement on the rebar positioning tooth, side welded connection had a plurality of connecting pieces frame connection spare week, every connecting piece is connected with the mould support pole setting of vertical setting respectively, the mould supports the mould supporting slanting pole that the fixedly connected with slant of pole setting middle part set up. The utility model discloses though increased the process of installing pier vertical reinforcement installation mould together, the totality engineering time reduces, uses manpower sparingly, and the reinforcing bar carries out the ligature according to the mould position simultaneously, and the wholeness is strong, has improved the installation quality of reinforcing bar.
