1.When prestressed CFRP plate is used to reinforce reinforced concrete structure, the anchorage end and anchorage end of anchorage should have at least one end.

1- tensioning anchor; 2- thrust frame; 3- guide screw; 4- tensioning support; 5- fixed end positioning board; 6- fixed end anchor; 7-M20 glue anchor bolt; 8-M16 bolt; 9- carbon fiber composite board; 10-M12 bolt; 10-M12 bolt; 11- reserved hole. After completion of tension, M20 gum bolt was implanted after tensioning completion.

2.The anchorage device for prestressed carbon fiber reinforced plastic plate can be used as plate anchorage, or small toothed rack anchorage (sharp teeth, toothed anchor and round tooth rack).

3. when designing the flat plate anchorage, the thickness of the cover plate and the base plate shall be no less than 14mm and 10mm, respectively, and the nominal diameter of the pressure bolts shall not be less than 22mm.

4.The design structure of tooth anchorage teeth, the tooth depth should be 0.3mm~0.5mm, tooth spacing should be 0.6mm~1.0mm. In order to prevent the sharp tooth anchorage will cut the prestressed carbon fiber composite plate, the anchor should be chamfered teeth in place.

5.when designing the anchor for the round tooth, the depth of the tooth should be 0.3mm~0.5mm, and the spacing between the teeth should be 0.6mm~1.0mm. In order to prevent the prestress carbon fiber composite board from friction with the anchorage at the exit of the anchorage, the anchorage of the anchorage should be parallel to the tension direction of the prestressed CFRP plate at the end of the anchorage.

6.The opening position and diameter of the anchorage shall be determined according to the actual project.
