An anchoring device for a wound composite carbon fiber plate

Abstract

The invention discloses a winding composite carbon fiber plate anchoring device. The device consists of an inner part and an outer part structures; the inner part is a carbon fiber plate winding ribbed steel column, and the outer part is an upper-lower two-piece clamping groove type steel plate; threads are arranged in a clamping groove of the outer steel plate at certain intervals; and coating colloid is engaged with the ribbed steel column. The manufacturing process for the carbon fiber plate winding ribbed steel column comprises the following steps of: winding a carbon fiber plate prepreg on a ribbed steel column, electrifying and heating the steel column until the prepreg is solidified for heating, specifically, the temperature for heating the steel column is controlled preferably to be between 165 DEG C and 175 DEG C, and the heating time of the steel column is controlled preferably to be 120 to 150 seconds; after the carbon fiber prepreg winding ribbed steel column is manufactured, the carbon fiber prepreg winding ribbed steel column is placed into the outer steel plate; the groove with a certain diameter is arranged in the outer steel plate; the outer steel plate is a two-piece structure and is provided with bolt holes with two different aperture sizes; bolts with small aperture size can be used for locking the upper and lower two-piece structures of the outer steel plate; and the anchoring device is fixed at a position to be reinforced of a concrete structure through bolts with large aperture size.

Description

technical field [0001] The invention belongs to the technical field of bridge reinforcement, in particular to a winding composite carbon fiber plate anchoring device. Background technique [0002] Due to the service life, environment, design and construction technology, force majeure or other unknown factors, the bridge structure has continuously exposed some health problems during its service. In order to avoid further damage to the bridge structure caused by these factors, how to reasonably and effectively strengthen the bridge structure has become the focus of research at this stage. Fiber Reinforced Plastics (FRP) is a new type of reinforcement material, among which Carbon Fiber Reinforced Plastics (CFRP) is widely used for its excellent corrosion resistance, high strength, and modulus design. Reinforcement maintenance works. [0003] In order to give full play to the high-strength advantages of carbon fiber panels, the carbon fiber panels are prestressed. The choice ...

Problems solved by technology

At present, there are still many problems and technical difficulties in the research of anchors for carbon fiber plates. Most anchors are bulky, inconvenient for on-site construction operations, and expensive

As far as its performance is concerned, when the limit state is reached, the carbon fiber plate anchor will be damaged or even completely destroyed before the carbon fiber plate is damaged, which cannot guarantee the full use of the high-strength performance of the carbon fiber plate
