At this time, the pressure-bearing part of the main steel body 1 is located at the wave arcs 11, and a plurality of equidistantly arranged assembly holes 13 are provided on both sides of the main steel body 1;

[0024] The compressive strengthening member 3 includes a main frame body 33 and support frames 31 installed on both sides of the main frame body 33. The outer wall of the support frame 31 is installed with connecting rods 35. The connecting rods 35 correspond to the assembly holes 13, and the ends of the connecting rods 35 are provided with connecting screw holes 36. Bolts are used to fix the connecting rods 35 from the outside;

[0025] The fastening member 4 is installed on the main frame body 33 for connecting the main frame body 33 and the main steel body 1.

[0026] Please refer to Figure 2 , the upper end surface of the support frame 31 is provided with a connecting arc 32. The connecting arc 32 is movably connected and fitted with the inner wall of the wave arc 11. The support frame 31 is an overall hollow triangular member.

[0027] In this embodiment, the connecting arc 32 whose outer surface fits the inner surface of the wave arc 11 can make the upper end of the support frame 31 closely fit the main steel body 1, so that the support frame 31 can effectively assist in supporting the main steel body 1 and improve the compressive resistance of the main steel body 1.

[0028] Please refer to Figures 1 - 2 , the assembly hole 13 is a vertical strip-shaped hole. Specifically, the strip-shaped assembly hole 13 can leave a certain activity space for the part of the bolt rod in the strip-shaped hole after the connecting rod 35 is fixed by bolts. When the structure is vibrated, it can vibrate slightly in the assembly hole 13 to avoid excessive vibration and the bolt rod has no space to move and break. Embodiment 2

[0029] Based on the above Embodiment 1, please refer to Figure 3 、 Figure 4 , the fastening member 4 includes a screw rod 41 and fastening nuts 42 arranged at both ends of the screw rod 41. The main frame body 33 is provided with a through activity hole 34, and the top of the main steel body 1 is provided with a fastening hole 14. The screw rod 41 passes through the activity hole 34 and the fastening hole 14, and both ends are respectively located at the upper end of the main steel body 1 and the lower end of the main frame body 33.

[0030] Please refer to Figure 1, a horizontal plane area 12 is provided at the center of the upper end surface of the main steel body 1 between the two wave arcs 11, and the fastening hole 14 is arranged in the plane area 12.

[0031] In this embodiment, the orifice of the movable hole 34 is located in the flat plane area 12, which can make the fastening nut 42 better fit with the main steel body 1 during the installation of the fastener 4, and can prevent the fastening nut 42 from loosening.

[0032] The working principle and usage process of the utility model: When using the channel steel to erect the steel structure, the compression-resistant reinforcement 3 is installed at the part of the steel structure where the pressure is relatively large. Align the connecting arc 32 of the support frame 31 with the inner wall of the wave arc 11 on the main steel body 1 at this part, so that the upper end of the support frame 31 fits with the main steel body 1. At the same time, slide the main frame body 33 to align the connecting screw hole 36 on the connecting rod 35 with the assembly hole 13. After using the bolt to pass through the assembly hole 13, screw it into the connecting screw hole 36 to complete the basic installation of the compression-resistant reinforcement 3. Then insert the screw rod 41 into the movable hole 34 of the main frame body 33 from below and make the screw rod 41 continue to pass through the fastening hole 14 on the main steel body 1. Then, put the two fastening nuts 42 on the upper and lower ends of the screw rod 41 respectively, and finally turn the two fastening nuts 42 to make them tightly fit with the plane area 12 of the main steel body 1 and the bottom of the main frame body 33 respectively. During this process, the support frame 31 is tightly attached to the main steel body 1 under the action of the fastening nut 42. When the channel steel is under pressure, the support part supports and resists the pressure of the wave arc 11, so that the wave arc 11 will not be deformed under pressure.
