Abstract

The invention discloses an FRP steel strand composite bar anchorage device and an anchoring method. The anchorage device comprises a soft metal pipe, an opening device, an anchor cup and a grouting material, the anchor cup penetrates into an anchoring area of an FRP steel strand composite bar, the soft metal pipe is fixed to the front end of the anchoring area of the FRP steel strand composite bar, the rear end of the anchoring area is opened through an opening device, the tail end of the anchor cup is filled with the grouting material after being blocked, and anchoring is completed after high-temperature curing. The anchorage device is simple in structure, small in size, high in anchoring efficiency, convenient to construct, capable of effectively improving the anchoring performance of the grouting material and a composite rib material and reducing the anchoring length, clear in stress direction, convenient to use, low in cost and high in reliability.

Description

Technical field[0001]The invention relates to the technical field of FRP steel strand composite reinforcement anchors, in particular to an FRP steel strand composite reinforcement anchor and an anchoring method.Background technique[0002]Stay cables are the main load-bearing components in the structural system of cable-stayed bridges. These components are under high stress for a long time. When they are served in harsh environments, fatigue, corrosion, and failure are aggravated, reducing the normal service life of the bridge and causing serious problems. The economic loss caused a major social impact. In order to take into account the service life and safety of the cable, effective measures must be taken to improve the corrosion resistance of the cable.[0003]FRP steel strand composite reinforcement not only overcomes the shortcomings of poor safety and high cost caused by the low modulus, poor ductility, and no yield section of pure FRP material, but also inherits the advantages of ...
