Abstract:Sheathing brick is widely used in Xiangshan Gang construction. This paper records the renovation technology of sheathing brick applied in the ancestral temples at Huishan Creek renovation project. The renovation process of sheathing brick is divided into four stages: disease investigation, demolition and dredging, body repair, and brick laying. The materials, craftsman procedures, tools, and key points of process operations at each stage are introduced in detailed. The renovation technology is compared objectively with the literature such as Yingzao Fayuan, Judgement Standard for Examining Quality of Construction in Traditional Chinese Architecture (for Southern Area) CJJ70-96 and so on to draw conclusions. This paper takes a detailed real record as an example to reveal the gap between the complex real scene and the text, in order to promote the research and optimization of the renovation technology of sheathing brick for the Xiangshan Gang building.
