Description

本発明は、柱を基礎コンクリートと土台とに接合するために用いる柱接合装置に関するものである。   The present invention relates to a column joining apparatus used for joining a column to foundation concrete and a foundation.

基礎コンクリート上の土台に設けた縦孔に係合した有底円筒状の接合筒を、前記基礎コンクリートから突出するアンカーボルトとこれに螺合したナットによって前記基礎コンクリートに締付け、円管状の接合枠の下部に円柱状の接合体を設けて成る接合材の前記接合体を前記接合筒に嵌挿し、該接合体と前記筒に接合枠を貫通させて前記土台に止着すると共に、土台より突出する接合材の前記接合枠と、該接合枠を下面に設けた嵌挿孔に嵌挿して前記土台上に立設した柱を、係止ピンで互いに止着した構造のものがある（例えば、特許文献１）。   A bottomed cylindrical joining tube engaged with a vertical hole provided in a foundation on the foundation concrete is fastened to the foundation concrete by an anchor bolt protruding from the foundation concrete and a nut screwed to the anchor bolt, and a tubular joining frame The joined body of the joining material formed by providing a cylindrical joined body in the lower part of the housing is inserted into the joined cylinder, and the joined body and the cylinder are passed through the joining frame and fixed to the foundation, and protrude from the foundation. There is a structure in which the joining frame of the joining material to be attached and the pillars that are erected on the base by inserting the joining frame in fitting holes provided on the lower surface are fixed to each other by a locking pin (for example, Patent Document 1).

特開２００３−９６９２２号公報JP 2003-96922 A

前記従来例は、構造上、接合材側の円形を、柱（嵌挿孔）側と土台（接合筒）側の円形に嵌挿し、かつ、円周方向の特定位置において互いに止着する構成を採るので接合材と柱乃至土台の組合わせ作業が煩雑である。   The conventional example has a structure in which a circular shape on the side of a bonding material is structurally inserted into a circular shape on a column (insertion hole) side and a base (bonding tube) side, and is fixed to each other at a specific position in the circumferential direction. Therefore, the work of combining the joining material and the column or base is complicated.

本発明は斯様な煩雑さを回避し、組付けが簡単で、しかも、接合強度の比較的優れた柱の接合装置を提供すべく創案したものである。   The present invention has been devised to avoid such complications, to provide a column joining apparatus that is easy to assemble and that has relatively high joining strength.

基礎コンクリート上の土台に設けた縦孔に係合した有底円筒状の接合基筒を、前記基礎コンクリートから突出するアンカーボルトとこれに螺合したナットによって底部片において前記基礎コンクリートに締付け、該接合基筒の筒状部片の上端に相対設した切欠に、上部片に一対の側部片を相対設して成る接合枠を係合し、該接合枠の前記上部片に設けた係合孔を通じて、接合基板と該接合基板の下端中央に突設した接続部片とで成る平板状の金属製接合板の接続部片を接合枠の前記側部片間に介在させ、該接続部片と前記側部片および前記筒状部片に接合杆を貫通させて前記土台に止着すると共に、該土台より突出する前記接合板の接合基板を柱の下端部に設けたスリットに係合して、該接合基板と前記土台上に配した柱の前記下端部を、組付け杆で互いに止着した構成とするのである。 A bottomed cylindrical joining base tube engaged with a vertical hole provided in a foundation on the foundation concrete is fastened to the foundation concrete at an bottom piece by an anchor bolt protruding from the foundation concrete and a nut screwed to the anchor bolt. Engage a notch provided on the upper end of the cylindrical part of the joining base cylinder with a joining frame formed by placing a pair of side parts relative to the upper piece, and an engagement provided on the upper piece of the joining frame. Through the hole, a connecting part piece of a flat metal joining plate composed of a joining substrate and a connecting part piece protruding from the center of the lower end of the joining substrate is interposed between the side parts of the joining frame, and the connecting part piece And the side piece and the cylindrical piece are attached to the base by penetrating a joining rod, and the joining substrate of the joining plate protruding from the base is engaged with a slit provided at the lower end of the column. Te, the lower end of the pillar arranged on the base with the bonding substrate set It is of a configuration that was fastened to each other with only rods.

本発明によれば、柱をアンカーボルト乃至基礎コンクリートに土台を介さないで直接的に取付けた構成を採るから堅牢な柱の接合装置を提供できることは勿論、円筒状の接合基筒に対し平板状の接合板を接続止着して該接合装置を得るものであるから、互いの組付け作業を簡単に行うことができ、また、接合状態時にあって柱に引き抜き力（外力）が負荷したとき（通常傾斜方向に作用する）、柱側の下面は土台に対し該柱の木質部と同時に金属製の接合板の端面（金属質部）も密接してその負荷を受けるから柱に対する補強効果を機能させ、耐久的な接合装置を提供できる。   According to the present invention, since a structure in which a column is directly attached to an anchor bolt or foundation concrete without using a base is adopted, it is possible to provide a robust column joining device, and of course, a flat plate shape with respect to a cylindrical joining base tube. Since the joining device is obtained by connecting and fastening the joining plates, the assembling work can be easily performed. Also, when the pulling force (external force) is applied to the columns in the joined state (Normally acting in the direction of inclination) The bottom side of the column functions as a reinforcement because it is close to the base and the end of the metal joint plate (metal part) at the same time as the base of the column. And a durable joining device can be provided.
