The invention relates to a formwork erecting device for steel column wrap angles and a construction method. The device comprises a column foundation; a steel column with an H-shaped section is mountedon the column foundation; formworks are arranged around the bottom of the column foundation; vertical back edges are arranged on the outer sides of the formworks; a first U-shaped clamp and a secondU-shaped clamp are installed at the two ends of a flange plate on one side of the steel column respectively; jackscrews are installed on the inner sides of the first U-shaped clamp and the second U-shaped clamp respectively; a first nut is arranged on the outer side of the first U-shaped clamp, the axis of the first nut is parallel to the axis of the jackscrews, and a second nut is arranged on theouter side of the second U-shaped clamp. One end of the first opposite-pull screw rod is connected with the first nut, and the other end of the first opposite-pull screw rod penetrates through the formwork to be fixedly connected with the first back edge; and one end of the second opposite-pull screw rod is connected with the second nut, and the other end of the second opposite-pull screw rod penetrates through the formwork to be fixedly connected with the second back edge. The formwork erecting device for steel column wrap angles is easy to manufacture and convenient and flexible to operate,the pull rods are arranged on the periphery with the steel column as the center, and formwork stress is uniform.
Description
Technical field [0001] The invention relates to building construction, in particular to a formwork supporting device and a construction method for steel column corners. Background technique [0002] As we all know, in the construction and metallurgy industry, almost most of the steel structure factory columns are welded I-shaped (or H-shaped) single-leg columns or double-leg columns, and many equipment columns, steel platforms and other column feet are usually required. Package column foot (or secondary grouting). Usually the plant package column foot is from -500mm elevation to +150mm, and the thickness is between 500~650mm, and the formwork support usually drills on the ground foundation to insert steel bars to fix the formwork system, and then use the scaffolding as the horizontal backing and diagonal support Make adjustments and reinforcements. The construction process is complicated and cumbersome, and the efficiency is low. Summary of the invention [0003] The technical ...
