Plastering Techniques for Storehouse Doorways

​土蔵は耐火性能をもつ建築として江戸時代以降盛んに建てられた．土蔵の出入口（戸前）は，火災時に弱点になることに加え，土蔵の”顔”として見栄えが意識され，優れた精度の段々状のかみ合わせや難易度の高い仕上げ技法，装飾的な表現が用いられることが多い．これらの左官仕事は技術的価値の高いものであるが，徒弟制度の職人間で伝えられてきたため文献に残らない情報が多い，戸前の形状や施工方法の詳細が記録に残らないまま技能・建築ともになくなりつつある．本研究は，土蔵戸前の生産技術を解明することを目的とする．

Earthen storehouses have been actively constructed since the Edo period (1603-1868) as fire-resistant buildings. In addition to being vulnerable to fire, the doorways of earthen storehouses were designed to look good as the "face" of the storehouse, so highly accurate stepped interlocking, difficult finishing techniques, and decorative expressions were often used. Although these plastering techniques are of high technical value, there is a lot of information that has not been preserved in the literature because they have been handed down among craftsmen under the apprentice system, and the details of the shape and construction method of the doorway have not been recorded, and both the skills and architecture are disappearing. The purpose of this study is to elucidate the production techniques of storehouse doorsteps.
