中国古代木构建筑经过长期外界环境因素的影响仍能保持完好,其原因与古代建筑的地仗密不可分。一方面地仗能保护木构件免受外界侵蚀,另一方面它是绚丽多彩的油饰彩画的基层。地仗是由血料、面粉、桐油、砖灰、石灰、纤维等多种无机物和有机物按照一定配比调配而成的混合物,其结构具有多层次的特点。本文阐述了地仗制作材料的性质和作用、地仗工艺的技巧和原理,剖析了古建地仗工艺中的不规范操作与常见病害间的关系,旨在寻找古代地仗牢固耐久的根本原因。 After a long period of external environmental factors, Chinese ancient wooden buildings can still remain intact. The reason is closely related to the ancient mantle of ancient buildings. On the one hand, it can protect wood components from being eroded by the outside world. On the other hand, it is the base of colorful oil paints. The mantle is a mixture of various inorganic and organic materials such as blood materials, flour, tung oil, brick ash, lime, and fiber according to a certain ratio, and its structure has multi-level features. This article describes the nature and function of mantle production materials, the techniques and principles of mantle technology, and analyzes the relationship between the non-standard operation and common diseases in ancient mantle mantle technology, aiming to find the root cause of the ancient mantle’s strong and durable. .
