There is a structure in which a mortise stick standing on the base is inserted into a pillar standing on the base, and the pillar and mortise stick are fixed to each other with a drift pin (for example, Patent Document 1) .

特開２００２−２９４８８２号公報JP 2002-294882 A

前記従来例は、いわば土台側にほぞ棒を設け、該ほぞと柱を係止杆（ドリフトピン）で止着した点において柱側にほぞを設けた所謂ほぞ接合で大きく相違するものであるが、前記ほぞ棒を立設した基盤を土台側に固定するには、土台と該基盤をアンカーボルトとこれに螺合したナットによって同時に基礎コンクリートに締付けなければならず、土台上に複数本の柱を土台に立設するに際しては、土台毎に存する各基盤を同時に位置合わせをする必要があるので、該組合わせ作業が煩雑である。   In the conventional example, a tenon stick is provided on the base side, and the tenon is provided with a tenon on a pillar side in the point that the tenon and the column are fixed with a locking pin (drift pin). In order to fix the base on which the tenon stick is erected to the base side, the base and the base must be fastened simultaneously to the foundation concrete by anchor bolts and nuts screwed to the base, and a plurality of pillars are provided on the base. When the base is erected on the base, it is necessary to align the bases existing on the base at the same time, so that the assembling work is complicated.

基板に螺杆を立設して構成した固定基材の基板をアンカーボルトとこれに螺合したナットによって基礎コンクリートに締付け、該基板を介して前記基礎コンクリート上に載置した土台を、該土台に嵌挿した前記螺杆の上端に接合材の接合板を介して締付け筒を螺合して前記基礎コンクリートに締付けると共に、前記接合板上に立設して前記接合材を構成する接合杆と該接合杆を嵌挿した柱を係止杆によって互いに固定した構成としたものである。   A fixed base board constructed by standing up a screw on the board is fastened to the foundation concrete with an anchor bolt and a nut screwed to the anchor bolt, and a foundation placed on the foundation concrete via the board is attached to the foundation. A fastening cylinder is screwed onto the upper end of the inserted screw through a joining plate of a joining material and fastened to the foundation concrete, and the joining rod which stands on the joining plate and constitutes the joining material and the joining The pillars into which the scissors are inserted are fixed to each other by the retaining scissors.

本発明によれば、柱を基礎コンクリートに土台を介して直接的に固定でき、ボルトによる縦方向の土台固定のため土台欠損が小さく、他の加工を併設（在来仕口のアリ等）でき、耐加力（引抜き力）性の有る、堅牢な柱の固定状態を得られ、しかも、組付け作業が簡単で斬新な構造の、木造建物における柱の固定装置を提供できる。   According to the present invention, the pillar can be fixed directly to the foundation concrete via the foundation, and the foundation defect in the vertical direction by bolts is small, so that the foundation defect is small, and other processing can be added (such as ants of conventional joints). In addition, it is possible to provide a column fixing device in a wooden building, which can obtain a solid column fixing state having a force resistance (pull-out force) and has a simple structure and a novel structure.
