WOODY BEAM-COLUMN FRAME
PROBLEM TO BE SOLVED: To provide a woody beam-column frame capable of securing predetermined cross-sectional performance, even if the height dimension of a horizontal member is lowered.SOLUTION: A woody beam-column frame 2 comprises second floor columns 20A, 20B, and a woody horizontal member 21 stretched over the second floor columns 20A, 20B. The woody horizontal member 21 comprises multiple woody long members 30 disposed roughly in parallel and separated from each other by a prescribed space and a woody structural plywood 26 connecting upper end faces of the long members 30. A longitudinal section of the woody horizontal member 21 is formed in an upside-down concaved shape. The present invention improves the rigidity of a girder 22 by the structural plywood 26; therefore, the cross-sectional performance of the same level as the case of the girder structured with one timber can be secured even if the height of the girder is lowered. As a result, the height of a building 1 provided with the girder 22 can be lowered, and the horizontal earthquake load acting on the building 1 can be reduced in case of an earthquake, so that the structural safety of the building 1 can be heightened.SELECTED DRAWING: Figure 4
【課題】横架材の高さ寸法を低くしても所定の断面性能を確保できる木質柱梁架構を提供すること。【解決手段】木質柱梁架構２は、２階柱２０Ａ、２０Ｂと、２階柱２０Ａ、２０Ｂに架け渡される木質横架部材２１と、を備える。木質横架部材２１は、所定間隔離れて略平行に配置された複数の木製の長尺部材３０と、長尺部材３０の上端面同士を連結する木製の構造用合板２６と、を備え、木質横架部材２１の縦断面は、上下反転した凹形状となっている。本発明によれば、構造用合板２６により大梁２２の剛性が向上するので、大梁を１本の木材で構成した場合に比べて、大梁の高さ寸法を低くしても、同程度の断面性能を確保できる。その結果、この大梁２２が設けられた建物１の高さを低くできるので、地震時に建物１に作用する水平地震荷重を小さくでき、建物１の構造上の安全性を高めることができる。【選択図】図４
