再读先农坛神厨井亭木结构设计

Further Interpretation of the Structural and Dimensional Design of the Well Pavilion in the Divine Kitchen Complex of the Temple of Agriculture

本文在前人的先农坛神厨井亭大木结构实测图的基础上,运用全站仪、三维激光扫描仪进行了部分补测工作。通过现有数据的分析,本文初步推算出古代匠人在井亭大木尺寸设计中采用了316.5毫米的营造尺,并进一步分析了大木尺度设计的基本方法和细节做法,讨论了该建筑的斗栱攒当、斜度、转角后尾相犯等设计细节问题。

Based on available survey drawings by previous researchers,the author used total station and 3D laser scanner to proceed supplementary survey of the timber structure of the well pavilions in the Divine Kitchen Complex of the Temple of Agriculture.Through data collection and statistic analyses,the article proposes primarily that the original construction ruler is measured 316.5 mm,and further interprets the detail dimension and design of Dougong bracket,and discusses the layout of Dougong,and the pitch of Ang,the cantilever component in Dougong,and the compromising methods at the corners to settle constructional intervention as well.
