造となる。According to the present invention, the fastening with the high-strength bolt can be easily performed by utilizing the opening portion, and the square steel pipe column and the diaphragm are connected at the factory side and are carried to the site. In that case, since there is no conventional beam bracket, it is possible to transport a large amount of the pillar material. further,
When assembled as a connection between a square steel pipe column and a beam on site, a cross-section defect occurs at the part of the square steel pipe column that has an opening, but the cross-H-shaped cross-section diaphragm placed inside compensates for this cross-section defect. The joining structure provides a sufficient force transmission.
