[0024] When the utility model is in use, the spacing adjustment structure is controlled to work according to the length of the steel structure column beam, and the supporting sliders 6 at both ends move toward each other, and the two ends of the steel structure column beam are respectively placed in the support plates 9 on the supporting sliders 6, and the fixing structure is controlled to work, and the pressing plate 15 moves down, and the two ends of the steel structure column beam are respectively fixed by the pressing plate 15. When the steel structure column beam is straightened, the pressing and straightening structure is controlled to work, and the straightening plate 4 is pressed down to straighten the steel structure column beam. In the process of straightening the steel structure column beam, the slow-down structure works, and the limiting support block 14 at the lower end of the support plate 9 can have a small end displacement, which is used to make up for the distance between the two ends extending on both sides during the straightening process of the steel structure column beam, and can effectively avoid the problem of loosening of the fixing effect of the pressing plate 15 and the steel structure column beam.
[0025] The spacing adjustment structure also includes a first screw rod 8 rotatably connected to the bottom bracket 1, an inner wall at one end of the support slider 6 is fixedly connected to a first screw barrel 7 threadedly connected to the first screw rod 8, one end of the bottom bracket 1 is fixedly connected to a limiting support rod 13, and the inner wall at the other end of the support slider 6 is slidably connected to the limiting support rod 13.

The threaded parts at both ends of the first screw rod 8 are respectively matched with the corresponding first screw barrel 7 threads in the supporting slider 6, thereby driving the supporting slider 6 to move toward each other, and adjusting the distance between the support plates 9 on the supporting slider 6, which can effectively cope with steel structure columns and beams of different lengths and avoid the displacement of the steel structure columns and beams during the straightening process.
[0027] A cushion block 18 is disposed at the bottom of the supporting sliding block 6 , and the cushion block 18 is slidably connected to the upper surface of the bottom bracket 1 .
[0028] like Figure 1 and 2 As shown, the pad 18 plays a role of limiting support for the support slider 6, which can effectively reduce the pressure of the steel structure column beam on the first screw rod 8 and the limiting support rod 13 during the pressing process.
[0029] The fixing structure further comprises a second screw barrel 12 fixedly connected to the inner wall of the upper end of the support plate 9 , the second screw barrel 12 is threadedly connected to the second screw rod 10 , and the lower end of the second screw rod 10 is rotatably connected to the pressing plate 15 .
[0030] like Figure 1 and 2 As shown in FIG. 3 , a handle 11 is provided at the upper end of the second screw rod 10, and the second screw rod 10 is driven to rotate by the handle 11. During the rotation process, the second screw rod 10 is threadedly engaged with the second screw barrel 12 on the inner wall of the support plate 9, thereby driving the pressing plate 15 at the lower end of the second screw rod 10 to move downward, and the pressing plate 15 is used to fix the steel structure column beam in the support plate 9.

[0032] like Figure 4 and 5 As shown, during the straightening process of the steel structure column and beam, since the pressing plate 15 on the support plate 9 is fixed to the steel structure column and beam, the two ends of the steel structure column and beam extend to both sides respectively during the straightening process, and the limit support block 14 at the lower end of the support plate 9 can undergo a small end displacement to slow down, effectively avoiding the problem of loosening of the fixing effect between the pressing plate 15 and the steel structure column and beam, and the spring 16 plays a role in resetting the movement of the limit support block 14.
[0033] The pressing and straightening structure further comprises a hydraulic cylinder 3 fixedly connected to the support frame 2 , and the output end of the hydraulic cylinder 3 is fixedly connected to the straightening plate 4 .
