Prestressed component with internal and external thread connecting holes, connecting structure and application method

The invention discloses a prestressed member with internal and external threaded connection holes, a connection structure and an application method. The prestressed member comprises a member body; a sleeve abuts against the connecting end face of the component body, threads are machined inside and outside the sleeve, and a conical hole is formed in an inner hole in the end, facing the connecting end face, of the sleeve. A prestressed tendon is fixed in the component body, the two ends of the prestressed tendon penetrate out of the corresponding sleeves, the ends of the prestressed tendon abut against the inner walls of the conical holes through wedge-shaped anchor pieces, and the sleeves are pressed on the connecting end faces. The connecting structure adopts a hollow connecting piece, a butt joint piece and a locking piece to realize the connection of the two component bodies; the hollow connecting piece is a bolt connected with the internal thread of the sleeve, and the end of the bolt is provided with an a
