摘　　要：为解决螺栓连接节点刚度低、滑移变形显著的问题,研发了一种基于植筋连接的预制装配式木构件接长节点,该节点可在获得良好刚度及节点紧密性的同时,采用保险螺栓防范植筋连接脆性破坏导致的节点突然解体,并通过碳纤维布增强端面抑制可能产生的木构件劈裂破坏。基于2根构件试验定性检验了节点设计意图实现情况并总结了可能的改进措施。A novel splicing joint for timber member is developed on the basis of bonded in steel rods, in aim of solving the problem of low rigidity and high sliding deformation of joints employing bolt connections. Good rigidity and tightness was obtained. Departure of the joint components was prevented by employing safety bolts, and CFRP sheet was used to preventing cracking of timber. Two sets of experiments were carried out to qualitatively examine the design concept of the joint. Some improvement measures were proposed.
