プレキャストコンクリート柱としては、例えば、遠心成型してある遠心成型コンクリート柱や、鋼管の内側にコンクリートを充填してある鋼管コンクリート柱がある。
遠心成型コンクリート柱と、鋼製梁とを、遠心成型コンクリート柱の外周部を環状に囲む鋼製リング部材を介して接合してある柱・梁接合構造では、従来、遠心成型コンクリート柱の製造時に、リング部材をコンクリートに埋め込み固定しておいて、このリング部材に鋼製梁を固定してある（例えば、特許文献１参照）。
また、鋼管コンクリート柱と、鋼製梁とを、鋼管コンクリート柱の外周部を環状に囲む鋼製リング部材を介して接合してある柱・梁接合構造では、従来、鋼製支持部材を、鋼製梁の接合高さに応じた高さ位置で、鋼管コンクリート柱の外周側に後付で溶接固定して、この鋼製支持部材に下端側を載置支持してあるリング部材に鋼製梁を固定してある（例えば、特許文献２参照）。 Examples of the precast concrete pillar include a centrifugal cast concrete pillar that has been centrifugally molded and a steel pipe concrete pillar that is filled with concrete inside the steel pipe.
In a column / beam joint structure in which a centrifugally formed concrete column and a steel beam are joined via a steel ring member that surrounds the outer periphery of the centrifugally shaped concrete column in an annular shape, A ring member is embedded and fixed in concrete, and a steel beam is fixed to the ring member (see, for example, Patent Document 1).
In addition, in a column / beam joint structure in which a steel pipe concrete column and a steel beam are joined via a steel ring member that surrounds the outer periphery of the steel pipe concrete column in a ring shape, a steel support member is conventionally used as a steel support member.

特開２００４−１９２５１号公報Japanese Patent Laid-Open No. 2004-19251 特開平５−２１４７３６号公報Japanese Patent Application Laid-Open No. 5-214736

遠心成型コンクリート柱と鋼製梁とを鋼製リング部材を介して接合してある従来の柱・梁接合構造では、遠心成型コンクリート柱の製造時に、リング部材をコンクリートに埋め込み固定する必要があるので、型枠などにセットしたリング部材がコンクリート充填の妨げになり易く、コンクリートの充填が不完全になって、コンクリート構造部分の強度が低下するおそれがある。
また、鋼管コンクリート柱と鋼製梁とを鋼製リング部材を介して接合してある従来の柱・梁接合構造では、鋼製支持部材を鋼管コンクリート柱の外周側に後付で溶接固定するので、鋼製支持部材を溶接固定する際の熱でコンクリートが劣化して、コンクリート構造部分の強度が低下するおそれがある。
本発明は上記実情に鑑みてなされたものであって、プレキャストコンクリート柱を遠心成型コンクリート柱で構成してあっても、鋼管コンクリート柱で構成してあっても、コンクリート構造部分の強度を特に低下させることなく、プレキャストコンクリート柱と鋼製梁とを鋼製リング部材を介して接合できるようにすることを目的とする。 In the conventional column / beam joint structure in which a centrifugally formed concrete column and a steel beam are joined via a steel ring member, it is necessary to embed and fix the ring member in the concrete when manufacturing the centrifugally formed concrete column. The ring member set on the formwork or the like tends to hinder concrete filling, and the concrete filling is incomplete, which may reduce the strength of the concrete structure portion.
In addition, in the conventional column / beam joint structure in which the steel pipe concrete column and the steel beam are joined via the steel ring member, the steel support member is welded and fixed to the outer peripheral side of the steel pipe concrete column by retrofitting. There is a possibility that the concrete deteriorates due to heat when the steel support member is fixed by welding, and the strength of the concrete structure portion is lowered.
The present invention has been made in view of the above circumstances, and the strength of the concrete structure portion is particularly reduced even if the precast concrete column is composed of a centrifugally formed concrete column or a steel pipe concrete column. It aims at enabling it to join a precast concrete pillar and a steel beam through a steel ring member, without making it.

本発明の第１特徴構成は、プレキャストコンクリート柱と、鋼製梁とを、前記プレキャストコンクリート柱の外周部を環状に囲む鋼製リング部材を介して接合してある柱・梁接合構造であって、前記プレキャストコンクリート柱の前記リング部材に対向する周面に周溝を形成し、前記周溝に充填して硬化させてある硬化充填材を介して、前記プレキャストコンクリート柱と前記リング部材とを一体に接着してある点にある。   A first characteristic configuration of the present invention is a column / beam joint structure in which a precast concrete column and a steel beam are joined via a steel ring member that annularly surrounds the outer periphery of the precast concrete column. The precast concrete column and the ring member are integrated with each other through a hardened filler formed on the circumferential surface of the precast concrete column facing the ring member and filled and cured in the circumferential groove. It is in the point where it adheres to.

Is made of centrifugally-cast concrete columns, the ring member is not embedded and fixed in the concrete during the production of centrifugally-cast concrete columns, and if the precast concrete columns are made of steel pipe concrete columns, the ring members A steel support member supporting the lower end side of the steel pipe is welded to the outer peripheral side of the steel pipe concrete column. Without the ring member can be fixed to the precast concrete column.
Therefore, even if the precast concrete column is composed of centrifugally molded concrete columns or steel pipe concrete columns, the precast concrete columns and the steel beams can be connected without particularly reducing the strength of the concrete structural part. It can be joined via a steel ring member.

本発明の第２特徴構成は、プレキャストコンクリート柱と、鋼製梁とを、前記プレキャストコンクリート柱の外周部を環状に囲む鋼製リング部材を介して接合する柱・梁接合方法であって、前記プレキャストコンクリート柱の前記リング部材に対向する周面に周溝を形成して、前記リング部材を、前記周溝を囲む状態で、前記プレキャストコンクリート柱の外周部に仮固定し、前記周溝に未硬化の充填材を充填して、その充填材が硬化した硬化充填材を介して、前記プレキャストコンクリート柱と前記リング部材とを一体に接着する点にある。   A second characteristic configuration of the present invention is a column / beam joining method for joining a precast concrete column and a steel beam via a steel ring member that annularly surrounds an outer periphery of the precast concrete column, A circumferential groove is formed on a circumferential surface of the precast concrete column facing the ring member, and the ring member is temporarily fixed to the outer peripheral portion of the precast concrete column in a state of surrounding the circumferential groove, and is not yet installed in the circumferential groove.

従って、プレキャストコンクリート柱を遠心成型コンクリート柱で構成してあっても、鋼管コンクリート柱で構成してあっても、コンクリート構造部分の強度を特に低下させることなく、プレキャストコンクリート柱と鋼製梁とを鋼製リング部材を介して接合できる。 [Action and effect]
A circumferential groove is formed on the circumferential surface facing the ring member of the precast concrete column, and the ring member is temporarily fixed to the outer peripheral portion of the precast concrete column in a state surrounding the circumferential groove, and an uncured filler is placed in the circumferential groove. Since the precast concrete column and the ring member are bonded together through the cured filler which is filled and cured, the downward engagement force with respect to the circumferential groove of the cured filler and the cured filler The ring member can be fixed to the precast concrete column due to the adhesive strength between the precast concrete column and the ring member. Without embedding and fixing members in concrete, and precast concrete columns with steel pipe concrete columns If you form, without the welded steel support member for supporting a lower side of the ring member on the outer peripheral side of the steel pipe concrete columns, it is possible to secure the ring member to the precast concrete column.
