Problems solved by technology
[0003] The use of prestressed reinforcement technology requires tensioning and anchoring of carbon fiber sheets. Although carbon fiber sheets have high tensile strength, their shear resistance is poor and it is not easy to anchor. Traditional surface friction and bolt locking are used to achieve carbon fiber sheets. Clamping and anchoring are prone to clamping, slipping, and bolt loosening, and its work reliability is poor. In addition, when using existing anchorages to anchor carbon fiber sheets, it is easy to cause stress concentration on the carbon fiber sheet and affect the limit of the carbon fiber sheet. strength and service life

The invention discloses a pawl-type carbon fiber plate anchor, which comprises an anchor sleeve and a clamping plate group, wherein a rectangular through hole through which the clamping plate group passes is formed in the anchor sleeve; the clamping plate group comprises an upper clamping plate and a lower clamping plate for clamping a carbon fiber plate; the clamping surfaces of the upper clamping plate and the lower clamping plate are corrugated surfaces; bars are arranged on the upper clamping plate and the lower clamping plate along the tension direction of the carbon fiber plate; and pawls matched with the bars are arranged in the anchor sleeve. The anchor is capable of effectively clamping the carbon fiber plate, ensuring the anchor performance and avoiding stress concentration of the carbon fiber plate.
Description
technical field [0001] The invention relates to the field of carbon fiber plate reinforcement, in particular to a pawl-type carbon fiber plate anchor. Background technique [0002] In recent years, high-strength composite fiber materials such as carbon fiber boards have been widely used in the reinforcement field of civil engineering. Usually, the carbon fiber plate is pasted on the surface of the reinforced component to improve the strength of the component. If the carbon fiber plate is stretched and anchored to the surface of the component, the bending strength and crack resistance of the component can be improved, the use efficiency of the composite fiber material can be improved, and the reinforcement cost can be reduced. [0003] The use of prestressed reinforcement technology requires tensioning and anchoring of carbon fiber sheets. Although carbon fiber sheets have high tensile strength, their shear resistance is poor and it is not easy to anchor. Traditional surface...
