The prestressed carbon fiber cloth anchoring device includes: an anchoring mechanism installed on the beam 1, the anchoring mechanism comprising an installation plate 3, an installation plate 4, a movable plate 5, a carbon fiber cloth body 6, two screws 8, and two resistance strain gauges;

[0024] Two resistance strain gauges are respectively mounted on two screws 8. Mounting plate 3 is mounted on the bottom of beam 1, and mounting plate 4 is mounted on the bottom of beam 1. Mounting plate 3 and mounting plate 4 are symmetrically distributed from left to right.

[0025] The movable plate 5 is installed on the bottom of the beam 1, and the movable plate 5 is located between the mounting plate 3 and the mounting plate 4.

[0026] The carbon fiber fabric 6 is disposed on the bottom of the beam 1, and the carbon fiber fabric 6 is located between the mounting plate 3 and the movable plate 5.

[0027] The bottom of the second mounting plate 4 has two symmetrical openings 10, and the bottom of the first mounting plate 3 has two symmetrical openings 11. The first mounting plate 3 forms a 1x1 buckle through the two openings 11, and the second mounting plate 4 forms a 2x2 buckle through the two openings 10. The two ends of the carbon fiber cloth 6 are respectively wound and connected to the 1x1 buckle and the 2x2 buckle.

[0028] The anchoring mechanism also includes a first fixing block 61, a second fixing block 7, two screws 8 and two nuts 9. The first fixing block 61 is installed on the bottom of the second mounting plate 4, and the second fixing block 7 is installed on the bottom of the movable plate 5.

[0029] Two screws 8 are symmetrically mounted on the fixing block 7, and two nuts 9 are symmetrically mounted on the carbon fiber cloth body 6. One end of each screw 8 passes through the two nuts 9 and is screwed into the two nuts 9.

[0032] The fixing component 12 and fixing component 2 13 include, but are not limited to, expansion bolts.

[0033] Two support brackets 2 are installed in appropriate positions to support beam 1 and provide a stable foundation for subsequent anchoring operations.
