【産業上の利用分野】この発明は、梁と柱の接合構造に
関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam-column joint structure.

要である（このような接合方法を保有耐力接合と呼
ぶ）。However, the beam 50 is not provided.
When the cross section is increased, since the proof stress of the joint is not sufficient, there is a risk of fracture before reaching a plastic state when an external force is applied by, for example, earthquake motion. On the other hand, there is a stickiness in a building, and even if it partially breaks (cracks or yields), it will not collapse immediately, so it is rational to design with expectations for this. That is, it is necessary to design each member of the joint so as to exhibit a sufficient deformability (such a joining method is referred to as holding strength joining).
【０００４】したがって、この発明は上記保有耐力接合
に鑑みてなしたもので、その目的は接合部の耐力が十分
で耐震性に優れた梁と柱の接合構造を提供することであ

【課題を解決するための手段】この発明の梁と柱の接合
構造は、梁の端部に上下方向の少なくともいずれか一方

材を柱にボルト接合したことを特徴とするものである。The beam-to-column joint structure of the present invention is provided with a mounting member made of shaped steel projecting in at least one of the up and down directions at the end of the beam, and the mounting member is supported by the column. It is characterized by being bolted to.

ボルト接合部の耐力を向上させることができる。According to the structure of the present invention, when an external force is applied due to an earthquake or the like, the mounting member deforms to absorb the bending moment. That is, the mounting member having a larger section modulus than the beam ensures sufficient deformability and prevents breakage,
The proof stress of the bolt joint can be improved.

合部は、図１および図２に示すようになっている。DESCRIPTION OF THE PREFERRED EMBODIMENTS A beam-to-column joining structure according to an embodiment of the present invention will be described with reference to FIGS. In FIG. 3, reference numeral 1 denotes a beam, which is installed between a pair of columns 2 and 2. The beam 1 is an H-shaped steel, and the column 2 is a rectangular tube (FIG. 2). The joint between the beam 1 and the pillar 2 is as shown in FIGS. 1 and 2.

てボルト５，５により接合される。That is, the mounting member 3 is fixed to the end of the beam 1. The mounting member 3 is made of H-shaped steel and has ribs 4 ... Fixed on both sides of the web at one end and the middle. Then, as shown in FIG.
The outer surface of the one flange 3a is brought into contact with the end surface of the beam 1 and fixed by welding or the like. In this case, the upper flange of the beam 1 and the rib 4 fixed to one end are flush with each other, and the lower flange of the beam 1 and the web 4 fixed to the middle are flush with each other, so that the mounting member 3 is positioned below the beam 1. It is mounted so as to project in the direction. Further, bolt insertion holes are formed in both upper and lower ends of the other flange 3b. In the joined state of the beam 1 and the pillar 2, the other flange 3b of the mounting member 3 is brought into contact with the pillar 2 and joined by the bolts 5 and 5.

向上させることができる。In the joint structure of the beam 1 and the pillar 2 constructed as described above, the mounting member 3 is made of shaped steel, and the pitches 5 and 5 of the bolts are formed.
Therefore, when an external force is applied due to an earthquake or the like, the mounting member 3 is deformed to absorb the bending moment.
That is, the mounting member 3 having a larger section modulus than the beam 1 ensures sufficient deformability and prevents breakage up to the full plastic moment, thereby improving the proof stress of the bolt joint.

れ自体十分な変形能力を有する部材であればなおよい。For the beams on the top floor of the building, as shown in FIG. 4, there is no obstacle even if the mounting member 3 is projected upward. Alternatively, the structure may be such that it projects only upward. Further, the mounting member 3 may be another shaped steel, and it is more preferable that the mounting member 3 itself has a sufficient deformability.

When an external force is applied due to an earthquake, the mounting member deforms and absorbs the bending moment. That is, the mounting member having a larger section modulus than the beam ensures sufficient deformability, prevents breakage, improves the proof stress of the bolt joint, and is excellent in earthquake resistance.
