Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] Please refer to Figures 1-5 , a preset installation structure of a steel bar connector for a steel column of a steel structure, including a fixed steel bar 1 and a steel bar connector body 2. Symmetrically arranged arc-shaped tightening rings 3 are sleeved outside the steel bar connector body 2. Symmetrically arranged first connecting ears 4 are fixedly connected to the outside of the arc-shaped tightening rings 3. First screw holes 14 are opened on the inner sides of the first connecting ears 4. A connecting shaft rod 5 is fixedly connected to one side of the arc-shaped tightening ring 3. An arc-shaped mounting plate 6 is fixedly connected to the end of the connecting shaft rod 5 away from the arc-shaped tightening ring 3. An elastic telescopic rod 7 is fixedly connected to the inner wall of the arc-shaped mounting plate 6. A correction plate 8 arranged in an arc shape is fixedly connected to the end of the elastic telescopic rod 7 away from the arc-shaped mounting plate 6. A connecting plate 9 arranged in an arc shape is fixedly connected to the side of the correction plate 8 away from the elastic telescopic rod 7. A plurality of mounting grooves 11 with equal groove diameters are opened on the side of the connecting plate 9 away from the correction plate 8. A plurality of equal-sized balls 12 are arranged inside the mounting grooves 11. Symmetrically arranged second connecting ears 13 are fixedly connected to the outside of the arc-shaped mounting plate 6. Second screw holes 15 are opened on the inner sides of the second connecting ears 13.

[0021] A group of adjacent first connecting ears 4 are detachably connected by bolts passing through the first screw holes 14. A group of arc-shaped tightening rings 3 are in contact with each other. This setting enables the first connecting ears 4 to be limited by bolts. A group of adjacent second connecting ears 13 are detachably connected by bolts passing through the second screw holes 15. The arc-shaped mounting plates 6 are symmetrically arranged. This setting enables the second connecting ears 13 to be limited by bolts. The number of elastic telescopic rods 7 is several. The elastic telescopic rods 7 are evenly arranged. A connecting spring 10 is sleeved outside the elastic telescopic rods 7. Both ends of the connecting spring 10 are fixedly connected to the arc-shaped mounting plate 6 and the correction plate 8 respectively. This setting enables the connecting spring 10 to cooperate with the elastic telescopic rods 7 for use, so as to correct the externally connected steel column of the steel structure. The connecting shaft rods 5 are evenly arranged. The correction plates 8 are evenly arranged. This setting enables the externally connected steel column of the steel structure to be corrected stably.

[0022] After the installation of the fixed steel bar 1 is completed, the steel bar coupler body 2 is preset at one end of the fixed steel bar 1. When installing the externally connected steel structure steel column, the externally connected steel structure steel column is placed between the connecting plates 9. The externally connected steel structure steel column exerts pressure on the connecting plates 9, and the connecting plates 9 act on the correction plate 8. The correction plate 8 acts on the elastic telescopic rod 7 and the connecting spring 10. The elastic telescopic rod 7 and the connecting spring 10 act on the arc-shaped mounting plate 6. At this time, the elastic telescopic rod 7 and the connecting spring 10 will be compressed to generate a reaction elastic force, so that the connecting plates 9 can tightly act on the externally connected steel structure steel column to correct it, so that the externally connected steel structure steel column can be directly connected to the steel bar coupler body 2. Then rotate the externally connected steel structure steel column, and the balls 12 installed through the installation groove 11 will act on the externally connected steel structure steel column, so that the movement of the externally connected steel structure steel column will not be affected when the correction plate 8 and the connecting plates 9 correct the externally connected steel structure steel column. After the installation of the externally connected steel structure steel column is completed through the preset installation structure of the steel bar coupler of the steel structure steel column, rotate the bolt at the first connecting ear 4 connected through the first screw hole 14, so that the first connecting ear 4 no longer limits the arc-shaped tightening ring 3. Then rotate the bolt at the second connecting ear 13 connected through the second screw hole 15, so that the second connecting ear 13 no longer limits the arc-shaped mounting plate 6, so that the arc-shaped tightening ring 3, the connecting shaft rod 5, etc. can be separated from the steel bar coupler body 2, thereby removing the components outside the steel bar coupler body 2, so that the steel bar coupler body 2 can stably connect the fixed steel bar 1 with the externally connected steel structure steel column.
