为实现实木椭圆榫接合家具节点的可拆装性，提出一种通过五金连接件改良椭圆榫节点的方法，测试T型构件的抗拔及抗弯力学性能，并分析节点加载过程中的力学行为及失效形式。结果发现，较对照椭圆榫节点，改良五金件连接节点的极限抗拔承载力达到5 614.61 N，提升了230%，但破坏弯矩降低了48.6%，刚性系数降低了45.6%。在保留实木椭圆榫外观及可拆装设计的前提下，本研究设计的可拆装式椭圆榫节点能满足多数木制品节点的使用强度要求，为后续实木可拆装式椭圆榫节点的优化设计提供依据及方法。
A detachable solid wood oval mortise-and-tenon joint strengthened by hardware connectors was designed in order to enable the disassembling of the joint in this study. The tensile and bending tests were conducted to evaluate the mechanical behavior and failure modes of typical and detachable T-shaped joints. The results indicated that the average tensile capacity of the detachable joints was 5 614.61 N, which is 230% higher than the typical joint. However, the mean breaking moment and the average stiffness coefficients were decreased by 48.6% and 45.6%, respectively. Generally, the strength of the detachable joint meets the application requirements of the wood product joint on the premise of retaining the appearance and enabling disassembly. This research provides the basic methodology for further development of the detachable hidden hardware connectors of wood furniture joints.
