Description
本発明は、木造建物に適用する柱と土台の接合装置に関するものである。 The present invention relates to a column and foundation joining apparatus applied to a wooden building.
基礎コンクリートに立設したアンカーボルトを、前記基礎コンクリート上に載置した土台と該土台上に重ね合わせた接合板を貫通させ、接合板より突出する該アンカーボルトの先端にナットを螺合して前記土台と接合板を前記基礎コンクリートに締め付けると共に、前記接合板を柱の下面に設けたスリットに嵌挿し、該接合板と前記柱を、柱の側面から打ち込んだ止着杆(ドリフトピン)で互いに接続した構造のものがある(例えば、特許文献1)。 Anchor bolts erected on the foundation concrete are passed through a base placed on the foundation concrete and a joining plate superimposed on the foundation, and a nut is screwed onto the tip of the anchor bolt protruding from the joining plate. The base plate and the joining plate are fastened to the foundation concrete, and the joining plate is inserted into a slit provided on the lower surface of the column, and the joining plate and the column are fixed by a fastening pin (drift pin) driven from the side surface of the column. There exists a thing of the structure connected mutually (for example, patent document 1).
前記従来構造のものは、柱の軸線位置に配したアンカーボルトを利用して柱と土台を基礎コンクリートに接合するという意味合いでは、強度的に優れた接合装置を構成するものであるが、柱に負荷される外力は、結局のところ、アンカーボルトに集中する構成を採るため、耐久的に問題がある。 The above-mentioned conventional structure constitutes a joining device excellent in strength in the sense that the pillar and the base are joined to the foundation concrete by using anchor bolts arranged at the axis position of the pillar. After all, the external force to be loaded has a problem in terms of durability because it is configured to concentrate on the anchor bolt.
本発明は、従来例の斯様な欠点に着目し、柱に対する外力の負荷がアンカーボルトに集中することなく、総じて耐久的な接合装置を提供することを目的として創案したものである。 This invention pays attention to such a fault of a prior art example, and it was created for the purpose of providing a generally durable joining apparatus without the load of the external force with respect to a pillar concentrating on an anchor bolt.
基板の上下両面に互いに同軸上にして上下の接合杆を突設して接合金具を構成し、土台に設けた凹陥部に縦穴を設け、該縦穴に前記下接合杆を嵌挿して前記凹陥部に係合した前記基板を、一対の平板状の座金部をコの字の連結枠で接続して構成した座金枠の、前記基板上に載置した座金部と共に、前記土台を載置した基礎コンクリート側から前記土台を貫通させたアンカーボルトとこれに螺合したナットによって前記土台に締付け、下端面に設けた係合溝に前記ナットを係合して前記基板上に立設した柱と、該柱に前記連結枠の水平部片を通じて嵌挿した前記上接合杆を固定杆で互いに止着した、構成とするのである。 The upper and lower surfaces of the substrate are coaxial with each other so that upper and lower joining rods project from each other to form a joint fitting, and a vertical hole is provided in the concave portion provided in the base, and the lower joint rod is inserted into the vertical hole to thereby form the concave portion. The base on which the base is placed together with the washer portion placed on the substrate, the washer frame formed by connecting the base plate engaged with the pair of flat plate washer portions with a U-shaped connecting frame. and a nut screwed on the anchor bolt and which was passed through the base from the concrete side fastened to the base, standing on the substrate engaging said nut engaging groove provided at the lower surface pillars, The upper joining rods inserted into the pillars through the horizontal pieces of the connecting frame are fixed to each other with a fixing rod.
図面は、本発明に係る柱と土台の接合装置の実施例を示し、図1は実施例の一部欠截正面図、図2は図1のb−b線断面図、図3は柱を省略して示した平面図である。 Drawing shows the Example of the joining apparatus of the pillar and foundation which concerns on this invention, FIG. 1 is a partial missing front view of an Example, FIG. 2 is bb sectional drawing of FIG. 1 , FIG. It is the top view shown abbreviate | omitting.
本発明は接合金具Aを用いて基礎コンクリートC上に載置した土台Bと該土台B上に立設した柱Pを接合して構成する。 In the present invention, a base B placed on the foundation concrete C and a column P standing on the base B are joined by using a joint metal A.
接合金具Aは、平面視正方形状の基板1の上下両面の中央に互いに同軸上にして上下の接合杆2,3を突設して構成し、基板1には前記接合杆2,3を介して一対の透孔4,4を前記土台Bの長手方向に沿う中央にして設け、上接合杆2に上下の関係においては互いに90度に位置をずらせた第二透孔5,5,5を設けたもので、実施例の接合金具Aは基板1と成る平面視方形状の金属板の中央に通し孔を設け、該通し孔に上下の接合杆3,4を構成する丸い金属管を嵌挿して組合わせ、該金属管と前記金属板を互いに熔着して形成したものであるが、実施例の形成手段を採ることは必ずしも必要としない。
The joining bracket A is configured by projecting upper and lower joining
この接合金具Aの前記基板1と一致する形状、大きさにして、基板1の厚さと一致する深さの凹陥部6を前記土台Bの上面の適所に設け、該凹陥部6の中央にして土台Bに設けた縦穴7に、接合金具Aの前記下接合杆3を嵌挿する一方、基板1に設けた前記透孔4に基礎コンクリートC側から土台Bに設けた貫通孔8を貫通させたアンカーボルト9を貫通させるようにして前記基板1を前記凹陥部6に係合せしめ、基板1より突出するアンカーボルト9の先端にナット10を螺合して接合金具Aを土台Bに締付けてある。
A
この土台Bに締付けた接合金具Aの基板1上には、下端面に設けた係合溝11に前記ナット10(該ナット10を螺合したアンカーボルト9の上端部は勿論)を係合するようにして前記柱Pを立設し、該柱Pと、柱Pの軸線上に設けた接合穴12に嵌挿した接合金具Aの前記上接合杆2を、柱Pに設けた貫通孔13と上接合杆2側の前記第二透孔5に固定杆14を嵌挿するようにして互いに止着して実施例装置としたものである。
