The inventiondiscloses aconnection structure of a tower crane supporting beam. The connection structure comprises a corbel type support seat andthe tower crane supporting beam, wherein the corbel type support seat comprises a pre-embedded piece arranged in a wall body and a supporting piece which is weldedon the pre-embedded piece; thepre-embedded piececomprises a pre-embedded steel plate which is level with the surface of the wall body; anchoring bars vertical tothe pre-embedded steel plate are welded at the back surface, facing the wall body, of the pre-embedded steel plate; anchoring blocksare weldedon the tail ends of theanchoring bars;theanchoring bars and theanchoring blocks are embedded in theconcrete wall body; the supporting piece comprises an upper horizontal supporting plate which is vertically welded on the front surface of thepre-embeddedsteel plate, a lower horizontal supporting plate, and a left vertical supporting plate and a right vertical supporting plate which are arranged between the upper horizontal supporting plate and the lower horizontal supporting plate; a middle horizontal supporting plate parallel to the upper horizontal supporting plate is welded between the left vertical supporting plate and the right vertical supporting plate; a middle vertical supporting plate parallel to theleft vertical supporting plate is welded between the upper horizontal supporting plate andthe middle horizontal supporting plate. By using the structure, the supporting beam is firmly connected with thecorbel type support seat, stress is table, and the quality and the safety of internal climbing tower crane construction are ensured.
