Technical Field

[0001] The present application relates to the technical field of steel bar skeletons, and in particular to a steel ring riveting structure of a steel bar skeleton. Background Art

[0002] The steel skeleton is pre-tied, and is often seen in brick-concrete construction: (structural columns, cantilever beams, etc.) are prefabricated and tied in advance, and are directly hoisted as a whole during construction. The steel bars are combined together to form a complete grid, which is figuratively called "steel cage", "steel mesh", "steel skeleton", etc. A complete steel grid is conducive to restraining concrete and improving the integrity of concrete components.

[0003] The steel ring of the steel frame is a type of steel frame. The steel plate is welded into a ring structure. A plurality of positioning pins are arranged on the inner side of the steel plate to realize the production of the steel frame. However, the existing positioning pins are mostly directly welded on the inner side of the steel ring during the installation process. Since the positioning pins are not convenient to fix during welding, the positioning pins are prone to tilt during welding, which in turn affects the normal installation of the positioning pins.

The cooperation between the positioning column 10 and the rib groove 4 on the nail body 5 facilitates the positioning of the two limit seats 9. When the nail body 5 is fully inserted into the circular groove 3, the clamping ring 17 directly compresses the spring 16, and then the rotating part 7 is manually rotated through an auxiliary tool. When the rotating part 7 rotates, it directly drives the screw 13 to rotate. When the screw 13 rotates, it directly drives the trapezoidal block 14 to move. When the trapezoidal block 14 moves toward the direction of the positioning column 10, it directly drives the two limit seats 9 to extend. When the limit seats 9 extend, they are directly inserted into the limit grooves, thereby facilitating the installation of the positioning nail on the steel ring body 1.
