[0022] During the installation process, the position of the side support block 5 can be adjusted inward or outward according to the width of both sides of the bridge, so that the side support block 5 can effectively support and reinforce the side of the bridge. When adjusting, the installation position of the waist frame 3 on the outer surface of the support column 2 is adjusted up and down, and the lifting rod 6 can be used to drive the side support block 5 to move outward or inward, thereby changing the position of the lifting and reinforcement, so as to match the use of bridges of different widths. After adjusting to the appropriate position, the connecting bolt 511 is installed between the corresponding two adjustment holes to fix the side support block 5 and the middle support block 4.

[0023] In order to make the side support block 5 more load-bearing, Figure 2 As shown, a plurality of slots 42 are provided between the left and right surfaces of the middle support block 4, and a plurality of support ribs 52 are fixedly installed in the side support blocks 5. The support ribs 52 are inserted and installed in the corresponding slots 42. The support ribs 52 can further support the side support blocks 5, thereby combining the lifting rod 6 and the cooperation between the C-shaped connecting part 51 and the connecting groove 41 to achieve effective support for the side support blocks 5 from three locations, so that the side support blocks 5 have a stronger load-bearing capacity.

[0024] Specifically, if Figure 3 As shown, the waist frame 3 includes two U-shaped steels 31, and a long rod bolt 32 is installed between the two U-shaped steels 31. The inner surfaces of the U-shaped steels 31 are symmetrically fixed with positioning plates 311, and the inner surfaces of the positioning plates 311 are in contact with the outer surfaces of the support columns 2. When installing the waist frame 3, the two U-shaped steels 31 are respectively in contact with the front and rear surfaces of the support columns 2, and then the long rod bolt 32 is used to penetrate the two U-shaped steels 31, and the outer surface of the support column 2 is clamped thereon. During installation, it should be noted that the bottom end of the lifting rod 6 should be first sleeved on the outer surface of the long rod bolt 32, and the lifting rod 6 should be located between the two U-shaped steels 31.

A fixing plate 8 is rotatably installed between the bottom ends of the support rods 7, and two mounting holes 81 are symmetrically provided on the upper surface of the fixing plate 8. A ground pin 82 is inserted and installed through the mounting holes 81. In actual use, the support rod 7 can adjust the position of its bottom, i.e., the fixing plate 8, to the inside or outside according to the installation height of the waist frame 3, so that the lower surface of the fixing plate 8 can fit the ground. After adjustment, the ground pin 82 is inserted through the mounting hole 81 to fix the fixing plate 8 to the ground.
