Here, one of the two H beams (H) may form a horizontal frame 21, and the other may form a vertical frame (22). The ends of the two H-beams (H) are butt-welded by cutting the ends at an incline, or the flange (F) of one H-beam is butt-welded to the flange (F) of another H-beam, and then the web (W) connected to each other between the H-beams is formed. The flanges blocking the space can be cut and connected in a continuous 'L' shape.

Thereafter, the connection between the webs W of the horizontal frame 21 and the vertical frame 22 is closed with the 'L'-shaped finishing plate 23 to increase the rigidity of the horizontal frame 21 and the vertical frame 22. there is. At this time, the closing plate 23 is preferably fastened to each H-beam (H) as a fastening member, but is not necessarily limited, and may be connected to each of the frames 21 and 22 by welding.

In addition, the frame structure 20 may further include a brace plate 24, the brace plate 24 is a vertical frame at the connection between the inner flange (F) of the vertical frame 22 and the horizontal frame 21 ( 22) and the horizontal frame 21 may be formed to be welded to each other.

In addition, the frame structure 20 may further include a stiffener plate 25, and the stiffener plate 25 has one web (W) and two flanges (F) on one or both sides of the web (W). ) may be configured to reinforce rigidity by connecting all of them.
