Use larch dimension lumber from China and imported truss plates to manufacture truss plate connection, and test the tension properties of the connection. The testing result point out that larch dimension lumber from China can take the place of SYP to manufacture timer truss. Three new truss plates were designed, which used domestic zinc coated steel. Test the behavior of domestic truss plate. The testing result point out that domestic truss plate meet the requirement of volume production, and new designs can advance the performance of truss plate connection. But domestic truss plate need to adjust the processing technic, then can use in actual production.%测试进口齿板与国产落叶松连接节点的拉伸性能,结果表明国产落叶松规格材完全可以替代美国南方松来制作齿板连接木桁架.提出3种国产齿板设计方案,使用国产镀锌钢板制作了国产齿板,并对国产齿板连接节点进行测试,指出国产齿板达到了批量生产的要求,改进方案可以提高齿板连接的性能,但国产齿板需要在加工工艺上进行调整,才能用于实际木桁架生产.
