Abstract

A secondary pouring column formwork support structure is provided to solve the technical problems of high cost, difficult formwork support adjustment, and difficult guarantee of vertical error of the column caused by the support of the secondary pouring formwork formed by erecting a scaffold. The scheme comprises a formwork support frame part, a formwork inclined pull rod part, and a formwork fixing frame part. The formwork support frame part comprises a horizontal support frame and an inclined support frame. The formwork inclined pull rod part comprises a formwork inclined pull rod and a formwork inclined pull rod base. The formwork fixing frame part comprises a right-angle formwork fixing frame. One end of a formwork and a back plate is arranged on the horizontal support frame, and the formwork and the back plate are connected into an integral whole by a group of formwork pull rods. The beneficial effects are that the secondary pouring formwork is erected and adjusted based on the poured column as a reference, the structure is simple, material is saved, the formwork is convenient to adjust, the formwork position has high precision, and the stability is good.
