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 non-return carbon fiber plate anchor device. The anchor device comprises an anchor device sleeve and a clamping piece group; the anchor device sleeve is provided with a rectangular through hole, and the clamping piece group comprises an upper clamping plate and a lower clamping plate which are used for clamping a carbon fiber plate; the clamping surfaces of the upper clamping plate and the lower clamping plate are waveform surfaces; the upper clamping plate and the lower clamping plate are provided with tooth bars along the carbon fiber tensioning direction, gears matching with the tooth bars are arranged in the anchor device sleeve, and the inner rings of the gears are provided with freewheel clutches; and the outer rings of the freewheel clutches are in transmission fit with the gears, and the inner rings of the freewheel clutches are fixedly arranged on the anchor device sleeve. The anchor device can effectively clamp the carbon fiber plate, ensures the anchoring performance, and avoids 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 non-return 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 s...
