The invention discloses a honeycombed-panel upright column. The honeycombed-panel upright column comprises an upper panel, a lower panel and a honeycombed core plate, wherein the cross-sectional shape of the upper panel is a U shape, the cross-sectional shape of the lower panel is also a U shape, integrated transverse plates are inwardly arranged on two sidewalls of a U-shaped opening respectively, the upper panel is formed by an integrated stamping die, the lower panel is also formed by an integrated stamping die, the upper panel is mounted inside the lower panel, the top ends of two sidewalls of the upper panel are fixedly connected with the inner sides of the two transverse plates of the lower panel, and the honeycombed core plate is filled in a cavity formed by the upper panel and the lower panel. Through arranging the one-time-formed honeycombed-panel upright column, the problem that the existing upright columns are out-of-flatness and incomplete, the stiffness/weight ratio is low and bent parts are prone to rupture is solved, and the honeycombed-panel upright column has many advantages of honeycombed panels.
