歴博甲本『洛中洛外図』屏風の桁のない町家について: 京都府向日市の須田家住宅をふまえて

摘要

This paper is intended an investigation of the town house without girders in the 'Rakuchu Rakugai-zu' Screen of Rekihaku "A" version. Although the construction method without girders was made possible by using dug-standing pillars or erecting a pillar on a foundation, there was no example in pictures historical records of ancient times to medieval times. Moreover, the method of construction is not used in the present construction. Therefore, the existence has been regarded as questionable. However, the roof truss of the Suda's residence in Muko-shi, Kyoto is similar with the construction method without girders. This example shows that the construction method without girders could be built. It seems reasonable to suppose that the construction method without girders was made by the intention to the simple building of the Age of Civil Wars.%本論は、歴博甲本『洛中洛外図』屏風から桁のない町家を取り上げた。桁のない構造が、古代から戦国時代以前の絵画史料に見当たらない事を確認した上で、18世紀初頭の町家遺構である須田家住宅に類似した小屋組を指摘して、実例として初めて紹介した。 これを元に、桁のない町家の登り梁構造を垂木と共に肯定し、清水が指摘した平側の壁見切りは不要と結論した。
