[0006] Preferably, a number of protective rods are fixed to the outer side of the upper end of the construction frame, and a protective frame is fixed to the upper end of the protective rods.

[0007] Preferably, the side of the construction frame is in close contact with the side of the rectangular high pier formwork, and the horizontal plate has through holes corresponding to the fixing bolts.

[0008] Preferably, the hydraulic cylinder is connected to the construction frame via a flange, and one end of the fixing plate is flush with the inner side of the construction frame.

[0009] Preferably, the protective rod and the construction frame are welded together by spot welding, and the horizontal plate and the construction frame are a welded integral structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a construction frame system. Two sets of construction frames are moved to the outside of a rectangular high-pier formwork using hoisting equipment. Fixing bolts are passed through the horizontal plates at both ends of the two construction frames, and nuts are screwed into the fixing bolts to assemble and fix the two construction frames. Positioning bolts are then screwed into the positioning holes. The upper and lower construction frames can then be connected and fixed using hydraulic cylinders. Activating the hydraulic cylinders pushes the upper construction frame upward. Then, the positioning bolts in the upper fixing plate of the upper construction frame are screwed into the corresponding positioning holes on the side of the rectangular high-pier formwork, achieving the effect of raising the upper construction frame. Afterward, the positioning bolts on the lower construction frame are unscrewed, and the hydraulic cylinder retracts, causing the lower construction frame to rise. Finally, the positioning bolts on the lower construction frame are screwed into the positioning holes on the side of the rectangular high-pier formwork, achieving the effect of moving the lower construction frame upward. Repeating this operation enables the construction frame to automatically climb the formwork, facilitating construction. Attached Figure Description
