ラムが入れられる。When the joint between a column with a closed cross-section, such as a rectangular steel pipe or steel pipe, and the steel beam is constructed by penetrating the column, stress transmission between the column and the beam will occur at the upper and lower flange positions of the steel beam inside or outside the column. Therefore, the diaphragm is normally placed horizontally as shown in FIG.

填性が悪い等の問題を抱えている。In the structure of disposing the diaphragm, the column is cut once at the position where the diaphragm is disposed, and the column is welded and connected after the diaphragm is installed. Further, when the pillar is made of steel pipe concrete, there is a problem that the filling of concrete near the joint is poor due to the diaphragm.
更に構造的にも接合部の応力伝達機構が複雑となり、
不明解な部分が多く残されている。In addition, the stress transmission mechanism of the joint becomes complicated structurally,
There are many unclear points.

る。The rib plate 3 is located on the plane on both sides of the flange as shown in FIG. 1-I, and on the elevation as shown by II, at the level of the upper and lower flanges of the steel beam 2, but at each flange position. Since the steps are formed in the directions orthogonal to each other, they are located on the upper surface side of the flange of one steel beam 2, and on the lower surface side of the flange of the steel beam 2 in the direction orthogonal thereto.
鉄骨梁２は第１図−Ｉに示すように例えば一方向に並
列するリブプレート3,3に挟まれる形で、柱１の側面に
