Tensioning and anchoring system of carbon fiber plate bundle and tensioning method thereof

Abstract

The invention discloses a tensioning and anchoring system of a carbon fiber plate bundle and a tensioning method thereof, the system comprises a prestressed plate bundle, the prestressed plate bundle comprises two anchoring sleeves, two anchoring plugs and a plurality of carbon fiber plates, the plurality of carbon fiber plates are sleeved with pre-buried casing pipes, a plurality of inserting piece holes which are arranged side by side in the same direction are formed in the anchoring plugs, the ends of the multiple carbon fiber plates extend out of the embedded sleeve and are inserted into the multiple insertion piece holes correspondingly, the anchoring insertion head is contained in the first end of the anchoring sleeve, and the second end of the anchoring sleeve is adjustably sleeved with a limiting lantern ring; a supporting insertion rod, wherein the first end of the supporting insertion rod is detachably inserted into the second end of the anchoring sleeve, and a supporting lantern ring is installed at the second end of the supporting insertion rod; and a pushing device which is provided with a first end and a second end which is propped against the supporting lantern ring. The problems that after an existing carbon fiber rib bundle is installed, the carbon fiber rib bundle cannot be straightly placed, and the performance of the carbon fiber rib bundle is affected due to bending are solved.

Description

technical field [0001] The invention relates to the technical field of building and bridge construction, in particular to a tensioning and anchoring system for carbon fiber plate bundles and a tensioning method thereof. Background technique [0002] Carbon fiber is an anisotropic material with high axial tensile strength but relatively low transverse shear and flexural strength, which severely limits the application of carbon fiber materials. Carbon fiber reinforcement is a common application form of carbon fiber materials. When the diameter of carbon fiber tendons is too large, its performance will be significantly reduced, so carbon fiber tendons are usually applied in the form of carbon fiber tendons. In engineering applications, due to the complexity of the construction site, there are deviations in the installation of carbon fiber tendons, the tendons cannot be placed straight, and there are bends. Therefore, after the force is applied, the force on each tendon in the ...
