Joint structure for h-beam

An H-beam joint structure for joining an end of steel materials adjacent to H-beam each other, wherein the steel materials have a flange and a web,

• comprising:
• a transmission plate arranged parallel to a front surface of the web on at least one side of the web of the H-beam and the steel material, and welded to a back surface of the flange;
• and
• a coupling plate connecting the H-beam and the steel material on an opposite side to the web on a side where the transmission plate is arranged, wherein
• a web of the H-beam, the web of the steel material and the transmission plate are bolted via the coupling plate.
