A carbon fiber anchor

Abstract

The invention discloses an anchorage device for carbon fiber plates. The anchorage device comprises an anchorage cylinder and at least two carbon fiber plates and is characterized in that an anchorage groove is formed in the anchorage cylinder, the carbon fiber plates are arranged in the anchorage groove, a force transferring base plate is arranged between each carbon fiber plate and the anchorage cylinder, protective colloids are arranged between the adjacent carbon fiber plates and between each carbon fiber plate and the anchorage cylinder, multiple rows of pressing screw hole groups are sequentially and axially formed in the upper part of the anchorage cylinder, each row of pressing screw hole groups comprises at least one pressing screw hole, a pressing bolt is arranged in each pressing screw hole, a first sealing device is arranged between each pressing bolt and the anchorage cylinder, and the pressing bolts are pressed on the force transferring base plates. The anchorage device has the advantages as follows: the pressing effect is better, the pressure stress borne by each carbon fiber plate at the corresponding load-bearing end is smaller through adjustment of the pressing bolts, accordingly, the tensile strength property of the carbon fiber plates is sufficiently developed, and the anchorage efficiency is higher.

Description

technical field [0001] The invention relates to an anchorage structure, in particular to a carbon fiber plate anchorage. Background technique [0002] Carbon Fiber Reinforced Polymer / Plastic (CFRP) has outstanding advantages such as light weight, high strength, high modulus, and corrosion resistance. It has been widely used in aerospace, automobile, civil engineering and other fields. Components composed of carbon fiber plates mainly composed of carbon fiber reinforced composite materials have been widely used in the reinforcement and maintenance of civil engineering structures such as bridge engineering and housing construction. [0003] At present, when most anchorages are used to anchor the carbon fiber plate, the carbon fiber plate is clamped in the groove by two splints with grooves on the inner surface, and the carbon fiber plate is set up and down through the two sides of the clip. The bolt locking mechanism makes the two clips firmly clamp the carbon fiber plate. Th...

Problems solved by technology

[0003] At present, when most anchorages are used to anchor the carbon fiber plate, the carbon fiber plate is clamped in the groove by two splints with grooves on the inner surface, and the carbon fiber plate is set up and down through the two sides of the clip. The bolt locking mechanism makes the two clips firmly clamp the carbon fiber plate. The carbon fiber plate at the anchorage area of ​​the anchorage with this structure not only needs a splint with a certain thickness to ensure the anchoring strength, so the overall volume is large. It takes up a lot of space, and the compressive stress from the loaded end to the free end is basically consistent, and the compressive stress on each part of the carbon fiber plate cannot be adjusted separately, so the carbon fiber plate always bears a large compressive stress at the loaded end , it is easy to cause damage to the carbon fiber plate in this area, so that the carbon fiber plate will be damaged in advance before its ultimate tensile strength is fully realized, so the anchoring efficiency of the anchorage used to anchor the carbon fiber plate is not high
