LOAD BEARING STRUCTURE OF WOODEN BUILDING
To provide a load bearing structure of a wooden building which can avoid reduction in a bearing force due to buckling, even when a strong horizontal force is applied, in the case where a resin foam tabular member whose compressive force on a side surface is equal to or greater than a predetermined value is used as a bearing material.SOLUTION: In a wooden building in which structure members comprising a pair of columns and a pair of horizontal members are combined, a foam resin tabular member which is not fixed to the structure member and fitted in a space part is provided. In the foam resin tabular member which is selected, a compressive force of a side surface is equal to or greater than 5 N/cm, the width is smaller than the width of the space part by a side surface clearance (t3), the height is shorter than the height of the space part by an upper part clearance (t4). When fitted in the space part, there is the side surface clearance with respect to the pair of columns, and a cutout part is formed which corresponds to the upper part clearance (t4) so that, when the colum inclines by receiving a horizontal force, upper and lower sides do not come into contact with the horizontal member. In order that a bearing force is exhibited in a range between 1/15 rad which the existing bearing wall cannot correspond and 1/8 rad at which the wooden building starts to collapse, t3 is chosen to be 0.5-3.5 mm, and the cutout part (t4) is chosen to be 25-50 mm.SELECTED DRAWING: Figure 1
【課題】側面の圧縮力が所定値以上の発泡樹脂板状部材を耐力材として用いる場合、強い水平力を受けても座屈による耐力の減少を回避し得る、木造建築物の耐力構造を提供する。【解決手段】１対の柱と１対の横架材からなる構造部材を組合せた木造建築物において、構造部材に固定されず、空間部に嵌込まれる発泡樹脂板状部材を備える。発泡樹脂板状部材は、側面の圧縮力が５Ｎ／ｃｍ２以上、幅が空間部の幅よりも側面クリアランス（ｔ３）だけ小さく、高さが空間部の高さよりも上部クリアランス（ｔ４）だけ小さく選ばれる。空間部に嵌め込んだとき一対の柱に対して側面クリアランスを有し、柱が水平力を受けて傾いたとき、上下辺が横架材に接触しないように、上部クリアランス（ｔ４）に相当する切欠部を形成する。既存耐力壁では対応し得ない１／１５ｒａｄから木造建築物が倒壊し始めるとされる１／８ｒａｄの範囲において耐力を発揮するように、ｔ３が０．５〜３．５ｍｍ、切欠部（ｔ４）が２５〜５０ｍｍに選ばれる。【選択図】 図１
