EARTHQUAKE-RESISTANT STRUCTURE FOR WOODEN BUILDING
To provide an earthquake-resistant structure for a wooden building which makes it possible to provide sufficient seismic retrofitting without removing an insertion lintel.SOLUTION: In an earthquake-resistant structure 1 for a wooden building according to the present invention, a thick pillar 4a is vertically provided on a cornerstone 12, and a thin pillar 4b is vertically provided on a laying base 2 connected to the legs of the thick pillar, and also an insertion lintel 5 is placed in a vertical space surrounded by the laying base 2, a roof beam 3, the thick pillar 4a and the thin pillar 4b. A bearing wall 91 is placed inside an upper frame 6b, which consists of the insertion lintel 5, the roof beam 3, the thick pillar 4a and the thin pillar 4b, so that in-plane shear deformation is suppressed, and also a joint portion between the thick pillar 4a and the laying base 2 is stiffened by using a pair of triangular stiffening members 92, 92 so that the rotational deformation at the legs of the thick pillar is suppressed.SELECTED DRAWING: Figure 1
【課題】差し鴨居を撤去することなく十分な耐震補強を行うことが可能な木造建築物の耐震構造を提供する。【解決手段】本発明に係る木造建築物の耐震構造１は、太柱４ａを礎石１２の上に、該太柱の脚部に連結された敷き土台２の上に細柱４ｂをそれぞれ立設するとともに、敷き土台２、小屋梁３、太柱４ａ及び細柱４ｂに囲まれた鉛直空間に差し鴨居５を配置してあるが、差し鴨居５、小屋梁３、太柱４ａ及び細柱４ｂからなる上段軸組架構６ｂの内側には、その面内せん断変形が抑制されるように耐力壁９１を配置してあるとともに、太柱４ａと敷き土台２との接合部位については、該太柱の脚部における回転変形が抑制されるように、一対の三角形状補剛部材９２，９２を用いて補剛してある。【選択図】 図１
