In this paper, interviews and measurements were conducted to clarify the architectural characteristics of earth and stone masonry huts around Mihara City, Hiroshima Prefecture. The results showed that the huts were used for ash burning as a fertilizer for agriculture and for making compost. In many cases, stone pillars were used for fire and decay protection, and horizontal or vertical members were sometimes inserted inside the earth-stone masonry walls. Furthermore, the results were compared with previous studies that investigated the surrounding area to determine the regional characteristics of the plan shape and specifications of the earth-stone masonry walls.

本研究は,地震が多発し雨の多い日本においては珍しい,土を積んだ壁を有する建築に着目して,現地調査,材料実験および環境測定を行ったものである。現地調査の結果,小屋の構成について,構造形式や軸組部分との関係から分類を行い,用途や分布地域,および土積み壁部分の構成との関係を確認した。土積み壁から採取したサンプルを対象とした材料実験では,建物の鉛直荷重を支える強度があり,土だけで積む場合より,同時に石も積む場合の方が細粒の土を用いる傾向が確認できた。環境測定では,土積み壁を持つ建物は,外気温と比べて温湿度が安定しており,土の持つ蓄熱性と調湿性による効果が確認できた。

In Kunisaki Peninsula, Oita Prefecture, there are huts with walls earth-stone masonry walls have been identified. In this study, the purpose and composition of the huts were investigated in order to clarify the architectural characteristics of the huts with earth-stone masonry walls. We conducted interviews and measured surveys. As a result, the following was found.(1) Many of the huts in the target area were built as places to raise livestock for farming, and even today, traces of waterers for livestock and mortise holes for fences can be seen in some of the huts. Since the middle of the Showa period (1926-1989), livestock have no longer been kept in the sheds, and their use has changed to storage. The spaces where the livestock spent their time needed to be well ventilated and comfortable, indicating the importance they placed on the livestock for farming.(2) All of the huts were built by owners before the previous generation, and in some cases the year of construction was more than 70 years ago or more than 100 years ago.(3) In some cases, the construction of the huts was done in collaboration with local residents, in addition to professional craftsmen.(4) The structure of the huts was classified into three categories: (a) wooden structure, (b) masonry structure, and (c) mixed structure, based on the percentage of earth-stone masonry walls out of the total wall volume and whether or not the walls support the load of the roof. As a result, wooden structures were the most common, and masonry and mixed structures were the least common. In relation to the region, wooden structures were most common in Kitsuki City and Kunisaki City, while masonry and mixed structures were most common in Bungotakada City.(5) The piles of earth and stones ranged from those with more stones and less earth to those with fewer stones and more earth. In the case of stone-heavy piles, the earth played a strong role as a joint material, and in the case of earth-heavy piles, it is possible that the earth was also used as a wall material.

In Japan, the cob construction is often used for fences, but is rarely used for buildings. These buildings are being dismantled by aging and change of owner. We conducted measurement on the warehouse and the wall built with the cob construction method around the Yamanobe road in Nara prefecture. As a result, it is found that there is relationship between the structure of the warehouse, the area and the application. Furthermore, it was possible to estimate the construction method from the states of the mud wall.
