摘要
针对侗族鼓楼宝顶构造的关键构件蜂窝斗栱,"相邻两朵斗栱斜栱相犯"的技术难题,解析了该现象产生的原因并用"相似三角形"方法破译并解决了该难题,最后以实际工程案例验证了该方法的正确性和适应性。同时深入探讨斜栱演变成蜂窝斗栱的相关机制,进而总结来自民间工匠的自由创造力及其呈现出的深刻学术意义。
The "cellular bracket" is a key component in the ethnic Dong drum-tower. For a long time, it has been a technical problem how two adjacent oblique bow-shaped bracket units are crossed. This paper analyzes the causes of the phenomenon, using the method of "similar triangles" to explicate and solve the problem, verifying the correctness and adaptability of the method by the practical projects.In addition, it examines relating mechanisms of the evolution from oblique bow-shaped bracket to the cellular bracket, concluding with freedom and innovation of local craftsmen and the profound academic significance.
