グ溶接で接合した場合に、溶接熱が大入熱であるため、
溶接線近傍に脆い層ができる。In the above-mentioned conventional structure, the filling property of concrete is not good in the lower part of the diaphragm, especially in the corners of the column. Also, when the diaphragm is joined by electroslag welding, the welding heat is a large heat input,
A brittle layer is formed near the weld line.

取付プレートが必要となる。Further, as shown in FIGS. 6 and 7, the eccentric joint between a column and a beam, which is often performed around the outside of a building or around an elevator core, exerts a tensile force P f on the weakest point of the diaphragm c. Therefore, it is usually impossible. Therefore, it is necessary to align the column core and the beam core as shown in FIGS. 4 and 5. For this reason, when mounting the curtain wall, a large stiffener h and a mounting plate are required as shown in FIG.
