WOODEN EARTHQUAKE-RESISTANT SHELTER AND EARTHQUAKE-RESISTANT REINFORCEMENT STRUCTURE
To provide an inexpensive and easy construction wooden earthquake-resistant shelter capable of reducing not only human damage caused by the collapse of wooden houses at the time of an earthquake but also the number of evacuees by suppressing the collapse of wooden houses to secure living space.SOLUTION: A wooden earthquake-resistant shelter is installed in a wooden building having a framework structure, and comprises four load-bearing walls 1 surrounding a space of a part of the wooden building. Each of the load-bearing walls comprises: two existing columns 110; a wall part 10 composed of square members 11 horizontally stacked in a plurality of stages between the existing columns; joining means 20 for joining the square members 11 to the existing columns 110; and a shear force transmission mechanism 30 for preventing lateral displacement between the horizontally stacked square members 11. The joining means 20 is constituted of a screw 20 which penetrates obliquely from an upper surface 11a of the square member 11 to an end surface 11b of the square member 11 and reaches an inside of the existing column 110 from a side surface of the existing column 110.SELECTED DRAWING: Figure 1
【課題】地震発生時の木造住宅倒壊による人的被害の低減だけでなく、木造住宅の倒壊を抑制して生活空間を確保することにより避難者数の低減をも図ることができる、安価で施工が容易な木造耐震シェルターの提供。【解決手段】軸組構造の木造建築物内に設置した木造耐震シェルターであって、木造建築物の一部分の空間を囲む四つの耐力壁１で構成され、耐力壁の各々は、二本の既設柱１１０と、既設柱間に複数段横積みされた正角材１１で構成された壁部１０と、各正角材１１を既設柱１１０に接合する接合手段２０と、横積みされた正角材１１どうしの横ずれを阻止する剪断力伝達機構３０とを備え、接合手段２０は、正角材１１の上面１１ａから正角材１１の端面１１ｂへ斜めに貫通し、既設柱１１０の側面から既設柱１１０の内部へ到達したビス２０で構成されている。【選択図】図１
