Embodiment 1
[0031] Such as figure 2 Among them, a row of bolt holes 7 is set on the U-shaped support frame 3 and the reinforcement plate 6, and the high-strength bolts 4 pass through the bolt holes 7 on the U-shaped support frame 3 and the reinforcement plate 6 from the outside to the inside, and the bolts are located on the U-shaped support frame. 3. A jacking nut 5 is arranged on the outer part; the high-strength bolt 4 makes its front end press against the steel backing plate 2, and at the same time, the jacking nut 5 is turned outward, so that the jacking nut 5 is tightened outward against the U-shaped support frame 3, And a certain prestress is applied to the steel backing plate 2 .
Embodiment 2
[0033] Such as image 3 Among them, two rows of bolt holes 7 are set on the U-shaped support frame 3 and the reinforcing plate 6, and the two rows of screw holes 7 are arranged at equal vertical intervals. The high-strength bolts 4 pass through the bolt holes 7 on the U-shaped support frame 3 and the reinforcement plate 6 from the outside to the inside, and set the tightening nuts 5 on the parts outside the U-shaped support frame 3; the high-strength bolts 4 make the front end tighten The steel backing plate 2 is rotated outwardly at the same time the clamping nut 5, so that the clamping nut 5 is pressed against the U-shaped support frame 3 outwardly, and a certain prestress is applied to the steel backing plate 2.
Embodiment 3
[0035] Such as Figure 4 Among them, three rows of bolt holes 7 are arranged on the U-shaped support frame 3 and the reinforcing plate 6, and the three rows of screw holes 7 are arranged at equal vertical intervals. The high-strength bolts 4 pass through the bolt holes 7 on the U-shaped support frame 3 and the reinforcement plate 6 from the outside to the inside, and set the tightening nuts 5 on the parts outside the U-shaped support frame 3; the high-strength bolts 4 make the front end tighten The steel backing plate 2 is rotated outwardly at the same time the clamping nut 5, so that the clamping nut 5 is pressed against the U-shaped support frame 3 outwardly, and a certain prestress is applied to the steel backing plate 2.
