Fabricated FRP pipe-steel reinforced concrete composite structure and construction method

The invention belongs to the technical field of civil engineering, and particularly relates to a fabricated FRP pipe-steel reinforced concrete composite structure and a construction method.The fabricated FRP pipe-steel reinforced concrete composite structure comprises a plurality of right-angle type connecting structures, the right-angle type connecting structures are located at the corners of the concrete composite structure correspondingly, and a plurality of T-shaped connecting structures are connected between the adjacent right-angle type connecting structures; the plurality of right-angle connecting structures and the plurality of T-shaped connecting structures form an assembled frame; the T-shaped connecting structure comprises a first horizontal composite beam, and a second horizontal composite beam and a first vertical composite beam are connected in a mortise and tenon assembly mode through a first connecting area formed through pouring. The right-angle type connecting structure comprises a third hor
