分でなく、かつ隅角部に変形を生ずる恐れがある。(Prior Art and Problems to be Solved by the Invention) The applicant has previously disclosed in JP-A-61-28252 a structure for joining a steel frame column made of a square steel tube and a steel beam using long bolts. We have developed a simple structure. In this case, the panel zone is filled with concrete, but this invention was developed for the purpose of developing a structure that omits this concrete filling and smoothes the stress transmission from the beam to the column and the beam. . In other words, it is desirable that the bolts be as close as possible to the side wall of the column considering that the stress transmission from the beam to the column and the beam is smooth and the bending of the side wall of the column is prevented. Has a rounded portion on the outer surface of the corner portion, a gap is formed between the column side wall and the joint plate provided at the beam end portion, stress transmission is insufficient, and the corner portion may be deformed.

て説明する。(Means for Solving the Problem) A joint plate in which a square steel pipe column having a rounded portion on the outer surface of the corner of the present invention and a steel beam are attached to the column side surface of the beam end, and a bolt penetrating the joint plate and the column is used. A gap formed between the rounded portion and the joint plate upon joining is filled with a reinforcing steel material. That is, the reinforcing steel material is used to transmit the stress from the joint plate to the side wall of the column with the corner portions. The details will be described below with reference to the illustrated embodiment.

材８が埋めてある。(Example) The steel column 1 is made of a square steel tube having a rounded portion 2 on the outer surface of the corner. A T-shaped metal 4 is fixed to the joint end of the steel beam 3 by a high-strength bolt or the like, and a joint plate 5 which is a vertical flange of the T-shaped metal 4 is abutted against the side surface of the column and is joined to the joint plate 5. The long bolt 6 and the nut 7 penetrating the pillar 1 are joined together. A reinforcing steel material 8 having a substantially triangular cross section is embedded in the gap formed between the rounded portion 2 and the joint plate 5.

トを示しているが通常のボルトでも同様である。The reinforcing steel material 8 is preformed as shown in FIGS. 5 and 6, or is formed on-site by overlay welding as shown in FIG. 7 and is attached to the column 1 before the steel beam 3 is assembled. The reinforcing steel material 8 can be attached to the joining plate 5 in advance. Reference numeral 9 indicates a fitting groove for the long bolt 6. In addition, although the above embodiment shows a long bolt, the same applies to a normal bolt.
（発明の効果） この発明は以上の構成からなり隅角外面にアール部を有

配することができる。(Effects of the Invention) Since the present invention fills a gap generated between a square steel column having a rounded portion on the outer surface of a corner and a joint plate of a steel frame beam with a reinforcing steel material, it is possible to secure the proof stress of the bolt joint,
It is possible to ensure the stress transmission from the beam to the column and the beam without causing deformation in the corners, and to dispose the bolts outside the center away from the center.
