ライスプレート等を添え、ボルト止めして接合したり、
或いは柱に梁を直接溶接したり、更に接合金物によって
接合するのが一般的である。In order to connect a beam to this type of column, a bracket is installed protruding from the column, a flange plate or splice plate is attached to this bracket, and the connection is done by bolting.
Alternatively, it is common to weld the beam directly to the column, or to connect it with metal fittings.

付けられるものであるため取り付けが極めて面倒である
。However, when a closed cross-section material such as a square steel pipe is used for a column, this type of reinforcing plate is generally attached to the inside of the column, making installation extremely troublesome.
又、柱の中にコンクリートを充填して鉄骨コンクリート
柱としたい場合、補強プレートが邪魔になって仕口部に
コンクリートを旨く充填出来ない場合もある。Furthermore, when it is desired to fill a column with concrete to form a steel-framed concrete column, the reinforcing plate may get in the way and it may not be possible to properly fill the joint with concrete.

この発明は、以上の構成から成るので、以下の効果を有
する。Since the present invention has the above configuration, it has the following effects.
■ 角形鋼管柱や円形鋼管柱等のように、仕口部の内側
に剪断補強プレートを設置することが比較的面倒な鉄骨
柱の場合、接合ボルトが仕口部の剪断補強プレートの働
きを有するため敢えて剪断補強プレートを設置する必要
はなく鉄骨加工が容易である。■ In the case of steel columns, such as square steel pipe columns and circular steel pipe columns, where it is relatively troublesome to install a shear reinforcing plate inside the joint, the joint bolt acts as the shear reinforcement plate at the joint. Therefore, there is no need to intentionally install a shear reinforcing plate, and steel frame processing is easy.
■ 又、剪断補強プレートを設置した場合と異なり、接
合ボルトによって仕口部の内側が上下に仕切られること
がないので、仕口部及びこれより下の方に充分にコンク
リートを充填することが可能となり強硬な鉄骨コンクリ
ート柱を構成することができる。■ Also, unlike when a shear reinforcement plate is installed, the inside of the joint is not divided into upper and lower parts by the joint bolts, so it is possible to sufficiently fill the joint and the area below it with concrete. This makes it possible to construct strong steel-framed concrete columns.
