【産業上の利用分野】鋼管柱或いは鋼管コンクリート柱
と梁の仕口構造に関する。[Industrial field of application] The present invention relates to a joint structure between steel pipe columns or steel pipe concrete columns and beams.

方式が用いられた。2. Description of the Related Art Steel pipe concrete columns are attracting attention as future structural members because they are structural members that are expected to have high yield strength and high rigidity and are excellent in deformability. However, for the joint between the steel pipe concrete column and the beam, the conventional through-diaphragm, inner-diaphragm and outer-diaphragm methods have been used.

【発明が解決しようとする課題】鋼管柱と梁の仕口部
は、強度、剛性の面から補強を要する。柱の内側に突起
のない外ダイアフラム方式では、図5(a)に示すよう
に仕上げ材との干渉を生ずるという欠点がある。The joint between the steel pipe column and the beam requires reinforcement in terms of strength and rigidity. The outer diaphragm system having no protrusions on the inner side of the column has a drawback that it interferes with the finishing material as shown in FIG.
【0004】通しダイアフラム及び内ダイアフラム方式
では、コンクリート充填用の孔を明けるが図5(b)に
示すように、強度を確保するため大きな孔を明けること
は不可能でありコンクリートの充填性は悪く、ダイアフ
ラム下端のコンクリート充填性に懸念が残るためコンク
リートの調合・充填法に対して多くの検討を要する。In the through-diaphragm and the inner-diaphragm system, holes for filling concrete are made, but as shown in FIG. 5 (b), it is impossible to make large holes to secure the strength, and the filling property of concrete is poor. However, since there is still concern about the concrete filling property at the lower end of the diaphragm, many studies are required for the mixing and filling method of concrete.
【0005】内ダイアフラム方式だとエレクトロ・スラ
グ溶接という特殊な技術を応用せねばならず、溶接規模
が大きくなり、作業も複雑であった。また一般の溶接よ
り入熱量も多く局部が高温になり調質鋼等に応用する場
合は特別の配慮を要した。With the inner diaphragm method, a special technique called electro-slag welding must be applied, the welding scale becomes large and the work is complicated. In addition, the amount of heat input is larger than in general welding, and the local temperature becomes high, so special consideration is required when applied to tempered steel.

溶接した例である。FIG. 4 shows an example in which the diaphragm 1 is obliquely welded to the steel pipe column in order to further improve the filling property of the concrete 5.
【0013】この仕口構造は縦リブ2で補強してあるの
で、コンクリート5を充填しない鋼管柱にも応用出来
る。Since this joint structure is reinforced by the vertical ribs 2, it can be applied to a steel pipe column which is not filled with concrete 5.

いし、調質鋼に対しても特別な注意を払う必要がない。According to the present invention, since the diaphragm 1 and the vertical ribs 2 are used, the holes of the diaphragm can be made large, and the filling property of the concrete 5 is good. In addition, it can be constructed by conventional welding methods without using electro-slag welding, does not require large-scale and complicated welding equipment, and does not need to pay special attention to heat-treated steel.
