山东新泰出土同心圆剑首连接技术研究

山东新泰周家庄出土了东周时期大量带有吴国特征的兵器,其中尤以青铜剑最具特色。为探讨东周同心圆剑首与剑茎的连接方式和连接结构,采用X射线探伤机、CT检测了3把同心圆首剑。检测结果显示3把同心圆首剑采用了2种铸造技术,即浑铸技术、铸接技术。其中2把铸接的同心圆首剑分别用2段式和3段式铸接成形。文章首次用CT清晰地展示了2把铸接的同心圆首上设置的榫头形状及分布状况。讨论了古代同心圆剑首连接技术的多样性、灵活性,说明了当时青铜连接技术已经非常娴熟、高超。

Studies on the jointing techniques used in sword pommels decorated with concentric circles and excavated from Xintai, Shandong Province

A lot of weapons made during Eastern Zhou period with typical Wu State characteristics have been unearthed in Zhoujia Village, Xintai City, in Shandong Province. Among those weapons, bronze swords are the most characteristic. In order to understand the construction and technique of jointing in pommels decorated with concentric circles and of handles of the swords made during the Eastern Zhou period,three such swords were analyzed by Xray and computer tomography (CT) methods. The results show that two casting techniques are used:onepiece casting and the casting-on technique. Two of the swords were formed by two-stage casting and one by three-stage casting. CT was used in this study to clearly demonstrate the shapes and distributions of the tenons in the two pommels decorated with concentric circles. In this article, the variety and the flexibility of the joining techniques applied in these ancient pommels are discussed. This work demonstrates the skills and excellent joining techniques used for making bronze objects during that time.
