Study of Roof Tiles in Lingnan Traditional Buildings and Roof Drainage Technologies
Abstract：Lingnan building is a key part of Chinese classical architectural schools, and the preservation & repair technologies of Lingnan traditional building roofs, which can embody Lingnan characteristics most, are especially important. The roof tiles of Lingnan traditional buildings and roof drainage technologies were taken as the main study objects. Under the background of Lingnan environmental features, effective roof repair technologies were summarized by combining the roof tile forms and texture types, analyzing the relationship between roof tiling form and roof drainage, and supplementing the traditional tile fabrication technologies, etc., expecting to provide a pragmatic reference for the roof repair of Lingnan ancient buildings.
摘要：岭南建筑是中国古典建筑流派类型的重要组成之一，作为最具岭南特色的岭南建筑屋面，其保留与修缮技术尤为重要。本文以岭南古建屋面之瓦片与排水修缮技术为主要研究对象，从岭南环境特点为背景，通过梳理屋面瓦片形态与材质类型、分析屋面铺瓦形式与屋面排水之间的关系、补充传统瓦片制作工艺等方面的研究分析，总结出较为有效的屋面修缮技术，为岭南古建筑屋面修缮提供可实施性的应用参考。
