Anchoring system and method for carbon fiber rib bundle

Abstract

The invention discloses an anchoring system and method for a carbon fiber rib bundle. The system comprises an extrusion type wire separating plate, an anchor cup, epoxy iron sand, a wedge block and an aluminum protective shell. The anchor cup penetrates through a bundled carbon fiber rib bundle, the carbon fiber rib bundle sequentially and correspondingly penetrates through corresponding holes of the extrusion type filament dividing plate, each carbon fiber rib penetrates through one aluminum protective shell, the tail of the carbon fiber rib bundle is inserted into the wedge block, the aluminum protective shells are clamped to the positions, with the large diameter, of the carbon fiber rib bundle, the extrusion type filament dividing plate is pushed backwards, and the carbon fiber rib bundle is fixed to the wedge block; and the anchor cup is moved backwards, so that the extrusion type wire separating plate is in close contact with the inner wall of the anchor cup, the sealing nut is screwed on, epoxy iron sand is poured from the front end of the anchor cup to the junction of the conical inner wall and the horizontal inner wall, low-modulus epoxy resin is poured into the horizontal end, and anchoring of the carbon fiber rib bundle is completed. The anchoring method for the carbon fiber rib bundle is high in anchoring efficiency, easy to operate, economical, reasonable and wide in application range.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an anchoring system and method for carbon fiber tendons. Background technique [0002] Components used in traditional structures, such as beams, slabs, columns, etc., under normal use conditions, the steel bars in the components will corrode under the action of air and humid environment, resulting in a decrease in the bearing capacity of structural components, and the expansion caused by corrosion will The concrete cracks and cracks are generated, which seriously affects the normal use of the components. [0003] In order to solve the hidden dangers of steel corrosion to structural safety, engineers have been exploring materials that can replace steel bars in recent decades. Carbon fiber reinforced composite bars have been recognized by engineers for their excellent corrosion resistance, high tensile strength and modulus. They can replace steel bars as stress bars, pre...

Problems solved by technology

[0004] The transverse mechanical properties of carbon fiber tendons are poor, and the anchoring method of steel strands cannot be used to anchor them. To give full play to the excellent performance of carbon fiber tendons, it must be anchored with a suitable anchoring method, otherwise carbon fiber tendons will The phenomenon of debonding or shear cracking will lead to low anchoring efficiency, and the excellent mechanical properties of carbon fiber tendons cannot be fully utilized. Therefore, the anchoring of carbon fiber tendons is the biggest challenge for the application of carbon fiber tendons.
