COLUMN-PLATE JUNCTION STRUCTURE IN WOODEN FRAMEWORK
PROBLEM TO BE SOLVED: To provide a column-plate junction structure in a wooden framework used for a secure and safe building with sufficient earthquake resistance achieved by a main column which penetrates the building at a central section thereof from a foundation to a roof and plates which are inserted into through-holes provided on the main column.SOLUTION: A main column has a pair of upper and lower through-holes which horizontally penetrate the same in directions normal to two column surfaces and partially intersect one another at a right angle. Each plate has a horizontal upper surface along a longitudinal direction and an inclined lower surface along the longitudinal direction. A horizontal upper surface of a lower plate which penetrates the lower through-hole has a cut-out section at an intersection portion where the same intersects with an upper plate which penetrates the upper through-hole. The upper and lower plates are engaged with each other at the intersection portion with the upper plate inserted into the cut-out section on the lower plate and a gap section in the upper through-hole. In addition, the upper and lower plates are fixed to the main column with wedges knocked in gaps between an inclined surface of the upper plate and the cut-out section of the lower plate and between the lower plate and the lower through-hole in the directions opposite to insertion directions of the plates.SELECTED DRAWING: Figure 1
【課題】 建物の中央部に主柱を基礎から屋根まで貫き、その主柱の貫穴に横架材を貫挿させて支える地震にも充分耐えられる安全で安心な建物に用いる木造軸組における柱と横架材の接合構造を提供する。【解決手段】主柱の反対向する面に渡って水平方向に貫通する上方と下方一対の貫穴の一部が直角方向に互いに交差してなり、前記横架材は上面が長手方向に水平をなし且つ下面が長手方向に傾斜してなり、下方の貫穴を貫通する下方横架材の水平面には上方の貫穴を貫通する上方横架材との交差部に当たる部分に切欠部を形成し、該下方横架材の切欠部と上方貫穴を貫通する間隙部に上方横架材を貫通させて上下の横架材が前記交差部において相互に係合するように構成されると共に上方横架材の傾斜面と下方横架材の切欠部との間ならびに下方横架材と下方貫穴との間に横架材の挿入方向と逆方向に逆止楔を打ち込んで上方及び下方の横架材を互いに柱に固定する。【選択図】図１
