A bidirectional coupling device used for joining a steel pipe pile and an H-pile is provided to increase stiffness by coupling perfectly in structure and to install on each coupling device integrally without additional installation work by manufacturing a bent or a girder in a factory and carrying in a construction site. A bidirectional coupling device(1) used for joining a steel pipe pile and an H-pile comprises an inner connection pipe(11) covering a middle joint plate(13), welded with a connection reinforcement rib and connected to a steel pipe pile, a connection reinforcement rib(17) attached to the middle joint plate supporting an H-pile to the inner middle of the inner connection pipe and a vertical reinforcement member(15) attached to the upper part of the middle joint plate for reinforcing an H-pile to transfer the axial force of the upper part to the ground, an outer connection pipe(19) attached to the outside of the inner connection pipe and welded to the outside which the steel pipe pile is inserted and contacted when joining a pile, and mortar unifying the coupling device with the H-pile if an H-pile is located on the upper part of the coupling device. |
