The anchoring mechanism 4 includes a first anchoring plate 401, a cylinder 402, a limit plate 403, a limit rod 404, a tensioning anchor 405, an insert 406, an electric push rod 407 and an anti-slip block 408. There are two limit rods 404, and both limit rods 404 pass through the limit plate 403. The glass fiber reinforced plastic mesh body 3 is located between the two limit rods 404.

[0024] exist Figure 2 and Figure 3 In the figure, two baffles are installed on the top of the mounting seat 2, and the rear sides of the two limit rods 404 are respectively connected to the two baffles. Two slots are opened inside the tensioning anchor 405. The controller drives the cylinder 402 to start, which can drive the limit plate 403 to move. The moving limit plate 403 can drive the tensioning anchor 405 and the first anchor plate 401 to move synchronously.

[0025] exist Figure 2 and Figure 3 In the figure, two plug blocks 406 extend from one side of the tensioning anchor 405 to the inside of the two slots.

[0027] In summary, the tensioning anchoring device of the prestressed FRP mesh facilitates fixing one end of the FRP mesh body 3 by setting the first anchoring plate 401. The controller drives the cylinder 402 to start, which can drive the limit plate 403 to move. The moving limit plate 403 can drive the tensioning anchor 405 and the first anchoring plate 401 to move synchronously. By setting the limit rod 404, the limit plate 403 is ensured to be more stable during the movement, and the position of the FRP mesh body 3 is prevented from being offset. By setting the plug block 406 and inserting the plug block 406 into the slot, the tensioning anchor 405 and the first anchoring plate 401 can be connected, and the anti-slip block 408 is pushed into the positioning groove by the electric push rod 407 to prevent the plug block 406 from loosening.

After waiting for the glue to dry, the controller drives the cylinder 402 to start and drive the FRP mesh body 3 to be tensioned. At this time, the limit block 403 slides outside the limit rod 404 to keep the FRP mesh body 3 stable. When it reaches the appropriate position, the cylinder 402 stops and the first anchor plate 401 is fixed and stabilized by fixing screws 6.

[0029] In addition, the electric push rod 407 drives the anti-slip block 408 to exit the positioning groove, so that the insert block 406 can be separated from the tension anchor 405. The user can replace different fiberglass mesh bodies 3 according to the different sizes of the base plate 1 to better fix different base plates 1.
