11.瀬戸内農家の構造 : 香川・愛媛県 (11) FARM HOUSE STRUCTURE ALONG THE COAST OF THE SETO INLAND SEA : Kagawa and Ehime Prefecture
This paper is reported Japanese straw-roofed farm houses, which had been never studied before, at the field of structure. The area from Uwajima City to Shiratori Town along the coast of the Seto Inland Sea is treated, and the purpose of the study is to compare the result with plane and regional character of the area. There are six kinds of principal rafter combination and purlin and common rafter combinations in structure of roof truss. As of the structure of principal truss, it is made clear the Daikokubashira (main pillar) has been used and there have been six kinds of beam structure. At the wall structure, closed ones which are rare in Japan are founded. These structure have a regional and specific features and it also exactly suite to the climate of the area. Not only the farm house structure, in a small area along the Seto Inland Sea, has been made clear by this study, but also the relation between Tateana Jukyo and Koshyo Jukyo, which is thought to have been the origin of Japanese house group, and farm houses are defined in the same reason. It is the main problem in the history of farm house construction whether or not the origin of Seikei Yomadori (plastic four rooms) with two Daikoku-bashira (main pillar) in Kagawa Prefecture, has been Tateana Jukyo (pit Dwelling) in Tsuyama City, and Kuichigai Yomadori (crossed four rooms) in Ehime Prefecture has been Taisha-zukuri (grand shrine construction which resembles Kosho-Zukuri). The beautiful appearance of the old farm houses along the coast of the Seto Inland Sea makes us refreshing to our heart as the pure remains left by our ancestors, with the beautiful landscape.
