ム形式が用いられた。2. Description of the Related Art Steel pipe concrete columns are expected to have high yield strength and high rigidity and are also excellent in deformability. Therefore, they are attracting attention as future structural members. However, regarding the joints between steel pipe concrete columns and beams,
Through-diaphragm, inner-diaphragm, and outer-diaphragm types were used.

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。However, as for the through diaphragm and the inner diaphragm, the filling property of the concrete is poor, and on the other hand, the outer diaphragm type having no protrusion inside the column has a drawback that it interferes with the finishing material. In the inner diaphragm type, a hole for concrete filling is opened, but as shown in Fig. 4, it is impossible to make a large hole to secure the strength, and there is concern about the concrete filling property at the lower end of the diaphragm. Many studies are required for the filling method.
【０００４】そこで、この発明は内ダイヤフラム形式に
おいてコンクリート充填性を改善するため孔をを大きく
し、かつ補強を施したものである。Therefore, in the present invention, in the inner diaphragm type, the holes are enlarged and reinforced in order to improve the concrete filling property.

ト５を充填する。Means for Solving the Problems A hole for concrete filling is made in a diaphragm 3 and welded inside a steel pipe column 1.
Further, a vertical rib is installed on the inside of the steel pipe to which the flange of the beam 4 is attached, the flange of the beam 4 is welded to this portion, and concrete 5 is filled.

る。Beam 4 of diaphragm 3 having a circular hole
The reinforcing jig in which the vertical ribs 2 are welded to the portion where the flange is welded is welded to the portion where the flange of the beam 4 of the steel pipe column 1 is to be welded. The steel pipe column 1 and the beam 4 are welded at this portion to form a joint. After that, the steel pipe pillar 1 is filled with concrete.
【０００８】コンクリート充填用の孔としては、円形の
他に種々の形のものがあり図２（ａ）、（ｂ）、（ｃ）
にその例を示す。As the holes for filling the concrete, there are various shapes other than the circular shape, and there are various shapes shown in FIGS. 2 (a), 2 (b) and 2 (c).
An example is shown below.
【０００９】また、図１、図２の例では縦リブ２はダイ
ヤフラム３を上下に挟んだ形状となっているが図３
（ａ）は縦リブ２を２枚のダイヤフラム３の内側に溶接

３の外側に溶接した例である。In the example of FIGS. 1 and 2, the vertical rib 2 has a shape in which the diaphragm 3 is vertically sandwiched.
(A) is an example in which the vertical rib 2 is welded to the inside of the two diaphragms 3 to form a jig, and (b) is an example to be welded to the outside of the two diaphragms 3.
【００１０】縦リブ２は、必ずしも四枚である必要はな
く、コンクリート充填に支障ないよう複数枚の板部材で
構成することも出来る。The vertical ribs 2 do not necessarily have to be four, and may be composed of a plurality of plate members so as not to hinder concrete filling.
【００１１】この縦リブは、孔を大きくしたダイヤフラ
ムの耐力の不足分を鋼管の内外抵抗でとるように鋼管を
補強したものである。The vertical ribs are obtained by reinforcing the steel pipe so that the deficiency of the yield strength of the diaphragm having a large hole can be taken by the internal and external resistance of the steel pipe.
【００１２】なお、図は全て角形鋼管柱の例が示してあ
るが、円形鋼管柱にも応用できる。Although all the figures show examples of rectangular steel pipe columns, they can also be applied to circular steel pipe columns.

あるので、コンクリート充填用の孔が大きくなりコンク
リートの充填性は良好である。また、縦リブ２で補強し
てあるので、充分な強度が確保出来る。The effect of the present invention is that, since the longitudinal ribs 2 are reinforced, the hole for filling the concrete becomes large and the filling property of the concrete is good. Further, since it is reinforced by the vertical ribs 2, sufficient strength can be secured.
