檐口是中国古代木构建筑的重点装饰部位之一。汉代赋文中已有关于椽头加饰玉石构件(称为“壁珰”)的记载。在国内外考古发掘中,发现了相当于我国南朝时期的陶质椽头饰件(称为“椽当”或“椽木瓦”)。在宋代《营造法式》中,则有木质椽头盘子做法的相关条文。但在我国明清建筑实例中,却只存有彩画椽头的做法。本文据已知形象资料、出土实物和文献资料,对我国北魏、南朝及宋代椽头饰件的样式、尺寸和做法进行了探讨。 Qikou is one of the key decorative parts of ancient Chinese wooden architecture. The Han Dynasty has written on the Shantou decorative jade components (known as “the alcove”). In archaeological excavations at home and abroad, we found the equivalent of ceramic stiletto trims (referred to as “dang” or “singapore”) during the Southern Dynasties of China. In the Song Dynasty “Creating a French Style”, there were related provisions for the practice of wooden dumplings. However, in the Ming and Qing Dynasties architecture example in China, there are only the practice of painting and calligraphy. Based on the known image data, unearthed objects and literature materials, this article discusses the style, size and practice of the head ornaments of the Northern Wei Dynasty, Southern Dynasties and Song Dynasty in China.
