[0029] See Figure 4 A through hole is provided on the inner wall of the connecting ear 15, and the ends of the two adjusting springs 16 away from the slider 14 are fixedly connected to the inner wall of the slide 13, so that one end of the traction rope can be connected to the inner wall of the through hole, and the other end of the traction rope can be connected to the steel structure, thereby facilitating the lifting and traction reinforcement of the device. The two adjusting springs 16 make it possible to arbitrarily adjust the position of the slider 14 on the inner wall of the slide 13, thereby facilitating the adjustment of the position of the connecting ear 15, and at the same time, the slider 14 can be pushed back to its original position with the help of the force of the adjusting spring 16.

[0030] See Figure 3 Reinforcement blocks 6 are fixedly installed at the four corners of the constrained steel member 2. The bottom of the reinforcement block 6 and the constrained steel member 2 are both in contact with the top of the steel support core 1. The reinforcement block 6 can reinforce the constrained steel member 2, ensuring that the constrained steel member 2 will not break easily after being subjected to force after installation, thereby increasing its service life.

[0031] See Figure 3 and Figure 4 The top of the steel support inner core 1 is provided with an installation groove that is adapted to the shape of the pin 4, and the pin 4 is inserted into the inner wall of the installation groove. The outer side of the steel support inner core 1 is provided with a positioning groove that is adapted to the shape of the square rod 10 and corresponds to the position of the square hole 5. The square rod 10 is inserted into the positioning groove and the inner wall of the square hole 5, so that the square rod 10 can be used to position the pin 4 at the inner wall position of the installation groove, thereby realizing the connection and installation between the steel support inner core 1 and the constraining steel member 2.

[0032] See Figure 2 The push plate 9 is slidably connected to the inner wall of the fixed cover 7, and the side of the square rod 10 away from the stud 11 abuts against the push plate 9. The size of the square rod 10 is adapted to the inner wall size of the fixed cover 7, so that the stud 11 drives the square rod 10 to move and push the push plate 9 to slide on the inner wall position of the fixed cover 7, and then the elastic force of the return spring 8 can be used to push the square rod 10 to slide, thereby facilitating the removal of the square rod 10 to the outside.

The threaded ring 12 is fixed to the steel support core 1 by bolts, so that the threaded ring 12 can be used in conjunction with the stud 11 to stably position the square rod 10 in the positioning groove and the inner wall of the square hole 5. At the same time, the rotating rod is used to increase the convenience of the threaded ring 12 when rotating, so that the threaded ring 12 and the steel support core 1 can be firmly connected by bolts to further position the square rod 10.

[0034] See Figure 1 - Figure 3 Four mounting holes 3 are symmetrically opened on the inner wall of the constrained steel member 2. There are two constrained steel members 2 symmetrically arranged on the upper and lower sides of the steel support inner core 1, so that it is convenient to connect the constrained steel member 2 with the steel structure through the bolts and the mounting holes 3, thereby forming support for it. Through reasonable design, it is ensured that the steel support inner core 1 will not buckle when under pressure, so that it can effectively dissipate energy under external forces such as earthquakes and protect the safety of the main steel structure.

[0035] See Figure 1 - Figure 4 The outer edges of the steel support core 1 and the restraining steel member 2 are coated with a galvanized layer, so that a protective layer can be formed on the outer edges of the steel support core 1 and the restraining steel member 2 to ensure their aesthetics and prevent them from being easily corroded.

[0036] Working principle: When using this device, first take the restraining steel member 2 and insert the pin 4 at its bottom into the inner wall of the installation groove, then insert the square rod 10 into the inner wall position of the positioning groove and the square hole 5, so that the pin 4 can be stably positioned on the inner wall of the installation groove to realize the connection between the steel support inner core 1 and the restraining steel member 2, then the threaded ring 12 can be threadedly connected to the outer edge of the stud 11 to further realize the positioning of the other rod 10, ensuring that it will not be easily moved to the outside, then one end of the traction rope can be connected to the inner wall of the through hole, and the other end of the traction rope can be connected to the steel structure, so as to facilitate the connection. The device is used for lifting and pulling reinforcement. The position of the slider 14 on the inner wall of the slide groove 13 can be adjusted at will through two adjusting springs 16, which makes it easier to adjust the position of the connecting ear 15. At the same time, the slider 14 can be pushed to return to its original position with the help of the force of the adjusting spring 16. When the constrained steel member 2 needs to be disassembled, the threaded ring 12 can be removed first, and then the stud 11 can be pushed to drive the square rod 10 to move and push the push plate 9 to slide on the inner wall position of the fixed cover 7. Then, the elastic force of the reset spring 8 can be used to push the square rod 10 to slide to the side close to the stud 11, so as to facilitate the square rod 10 to be taken out to the outside.
