PROBLEM TO BE SOLVED: To provide a welding joint structure of a pole and a beam, remarkably improved in strength by providing a beam insert hole in a vertical pole of steel material and inserting and passing the beam into the beam insert hole of the pole to join both of them by welding. SOLUTION: This welding joint structure of a pole and a beam is composed of the vertical pole 1 of steel material, the beam 2 a little thinner than the pole, and the beam insert holes 3 provided in the pole 1. The beam 2 is passed through the beam insert holes 3, 3', and welded on the joint parts 5, 5' of the pole 1 and the beam 2. COPYRIGHT: (C)2004,JPO
