口接合の剛度を確保していた。 Conventionally, in joint joints between square steel pipe columns and H-shaped steel beams in steel frame structures, axial force, shear force, and bending moment are applied to the joints, so the columns and beams are simply joined using joint plates. Since it is not possible to maintain sufficient strength with the length, the rigidity of the joint joint required by the diaphragm was secured.

接出来る。 As mentioned above, at the joint between the square steel pipe column and the H-shaped steel beam,
If the diaphragm of the present invention is used, the steel pipe column on the mounting surface side of the wall will be provided with a band plate in the direction perpendicular to the outer end of the flange, so this joint will be different from the conventional one in which the flange protrudes outward. It can ensure a rigidity equal to or greater than that of the diaphragm, and the attached wall can be close to the steel pipe column with a gap equal to the thickness of the strip.
