[0025] Specifically, the upper clamping plate 1 and the lower clamping plate 2 are opened and closed to adjust the clamping width. Then, the upper clamping plate 1 and the lower clamping plate 2 with the adjusted size are fixed with the adjusting component. The frame 15 is used to support the first corner frame 11 so that it will not fall off under the beam. The upper clamping plate 1 and the lower clamping plate 2 are longitudinally clamped by tightening the first bolt 6. The first threaded rod 7 is used to connect the upper clamping plate 1 and the lower clamping plate 2 on the beam and under the beam, thereby achieving a tight fit with the original structure and enhancing the bending, shear and seismic performance.

[0026] Reference Figures 2-3 The adjusting assembly includes a first screw 3, the outer wall of which is threadedly connected to the interior of the upper plate 1. The interior of the upper plate 1 has an upper hole 4, and the outer wall of the first screw 3 is threadedly connected to the interior of the upper hole 4. The interior of the lower plate 2 has a lower hole 5, and the outer wall of the first screw 3 is threadedly connected to the interior of the lower hole 5. A connecting rod 10 is rotatably connected to the interior of the lower plate 2. The upper outer wall of the connecting rod 10 is movably connected to the interior of the upper plate 1. The lower outer wall of the connecting rod 10 is rotatably connected to a first corner frame 11. A first washer 12 is provided on the outer wall of the first corner frame 11.

[0027] Specifically, the upper plate 1 and the lower plate 2 are respectively provided with an upper hole 4 and a lower hole 5, so that after the upper plate 1 and the lower plate 2 are adjusted in position, the upper plate 1 and the lower plate 2 are fixed with the first screw 3, thereby achieving a tight fit with the original structure and enhancing the bending resistance, shear resistance and seismic resistance. The connecting rod 10 is used to connect the upper plate 1 and the lower plate 2 to the first corner frame 11, and the first gasket 12 is used to support the first corner frame 11 and the second corner frame 13.

[0028] Reference Figures 2-4 The outer wall of the first gasket 12 is provided with a second corner frame 13, and the interiors of the first corner frame 11, the first gasket 12, and the second corner frame 13 are all threaded with a second threaded rod 8; the outer wall of the second corner frame 13 is provided with a second gasket 14, and the outer wall of the second threaded rod 8 is threaded to the interiors of the second corner frame 13 and the second gasket 14; the outer wall of the second threaded rod 8 is threaded with a second bolt 9; the outer wall of the first corner frame 11 is provided with a frame 15; the outer wall of the frame 15 is provided with a fixing plate 16, and the interior of the fixing plate 16 is threaded with a second screw 17; the outer wall of the second screw 17 is threaded to the interior of the first corner frame 11, and the outer wall of the fixing plate 16 is provided on the outer wall of the first corner frame 11;

[0030] Working principle: First, place the frame 15 below the main beam, then place the lower plate 2 and the upper plate 1 above the main beam and below the frame 15. The lower plate 2 and the upper plate 1 are adjusted by the adjustment components inside, which can be used to adapt to beams of different widths. Loosen the first screw 3 so that the lower plate 2 and the upper plate 1 can slide left and right to adjust their size. Then tighten the first screw 3 to fix the adjusted lower plate 2 and the upper plate 1. Further tighten the first bolt 6 so that the lower plate 2 and the upper plate 1 can adapt to different thicknesses, thereby achieving a tight fit with the original structure and enhancing the bending, shear and seismic performance.

[0031] Rotate the connecting rod 10 to raise the first corner frame 11 to the bottom of the main beam. Place the second threaded rod 8 inside the first corner frame 11 and frame 15 and tighten it. Then tighten the second screw 17 to fix the fixing plate 16, thereby fixing the frame 15. Pass the second threaded rod 8 through the first corner frame 11, the first washer 12, and the second corner frame 13 and tighten the second bolt 9. Then pass the second threaded rod 8 through the second corner frame 13 and the second washer 14 and tighten the second bolt 9. This allows it to adapt to and fix support columns of different sizes. By replacing the frame 15, the first washer 12, and the second washer 14, the first corner frame 11 and the second corner frame 13 can be adapted to columns of different sizes, thereby achieving flexible adaptation to columns of different sizes, improving reinforcement efficiency, and enhancing the overall structure and durability.
