Wedge-shaped connecting joint for FRP (Fiber Reinforce Plastic) rib of concrete structure

The invention provides a wedge-shaped connecting joint for FRP ribs of a concrete structure. The wedge-shaped connecting joint comprises a plurality of circular pipes and a sleeve. The outer diameters of the round pipes change in the length direction of the round pipes in a one-way mode, the thick ends of the round pipes are close to one another, the sleeve wraps the round pipes, and the thin ends of the round pipes extend to the outside of the sleeve or are flush with the outer wall of the sleeve, so that the concrete structure FRP ribs are inserted into the round pipes respectively, and rapid connection of the concrete structure FRP ribs is achieved. Compared with the prior art, the wedge-shaped connecting joint for the FRP rib of the concrete structure does not damage the FRP rib of the concrete structure, is resistant to corrosion, capable of being prefabricated, light in weight and easy and convenient to connect and construct, and solves the connecting problem of the FRP rib of the concrete structure in
