Construction Method for Mounting Earthen Blocks

土は地球上のどこにでも存在し枯渇の心配の少ない資源である.乾燥固化しただけの土の資源循環性や吸放湿性能は今後の建築に活用できる利点といえる.日本では主として土を塗り重ねた小舞土壁構法が用いられてきたが,工期やコスト面での制約が多い.海外では版築や日干しレンガなど,幅広い使用方法が存在しているが,組積構法が多く,地震多発地域である日本には馴染まないものも多い.一方,ブロック状にユニット化された土を用いることで,難易度の高い技術や工期・コスト面の制約から解放できる可能性がある.

​本研究は,ブロック状の土を現場で容易に取り付けることのでき,構造安全性を確保できる構法を開発する.考案した構法のディテールが構造安全性に及ぼす影響を検討する.

Earth is a resource that exists everywhere on the earth, and there is little concern about its depletion. The resource recycling and moisture absorption/desorption properties of earth, which is only dried and solidified, are advantages that can be utilized in future construction. In Japan, the mud-bamboo wall construction method, which consists of layers of earth, has been mainly used, but it has many limitations in terms of construction period and cost. In other countries, a wide range of using earthen materials, such as rammed earth and sun-dried bricks, but many of them are assembled and are not suitable for Japan, which is an earthquake-prone region. On the other hand, the use of block-shaped earth units has the potential to free us from difficult techniques and constraints in terms of construction period and cost.

In this study, we develop a construction method that can be easily installed in building and ensures structural safety. The effect of the details of the proposed method on the structural safety will be investigated.
