Abstract

In this study, the effects were examined of wood species, processing types and processing time on diagonal tension performance of woodworking corner joint with double tenon and mortise. Test samples were prepared by using Scots pine (Pinus sylvestris Lipsky), sessile oak (Quercus petreae Lipsky) and black locust (Robinia pseudoacacia L.). Poly vinyl acetate (PVAc) adhesive was used to join the tenon and mortise corner joints. The samples were impregnated by using the method of immersion for 20 and 40 min with a mixture of wax / linseed oil (3 % paraffin, 10 % linseed oil, 87 % white spirit) and Imersol-Aqua. The test of diagonal compression was used to test 120 samples. In this study, the minimum strength decrease of around 68 % was obtained for Scots pine impregnated with Imersol-Aqua for 40 min and the highest strength increase of around 10 % was obtained for sessile oak samples impregnated with Imersol-Aqua for 40 min. The highest diagonal tension performance of 879.734 N·m was obtained for oak samples impregnated with Imersol-Aqua for 40 min., the lowest diagonal tension performance of 189.111 N·m was obtained for Scots pine samples impregnated with Imersol-Aqua for 40 min.

浸渍木工角接头的对角拉伸性能

研究了木材种类、加工类型和加工时间对木工双榫转角接头斜拉性能的影响。以樟子松（Pinus sylvestris Lipsky）、无柄栎（Quercus petreae Lipsky。使用蜡/亚麻籽油（3%石蜡、10%亚麻籽油、87%白酒）和Imersol Aqua的混合物浸渍样品20和40分钟。采用对角线压缩试验对120个样品进行了测试。在本研究中，用Imersol Aqua浸渍40分钟的苏格兰松的强度最低下降了约68%，而用Imersol-Aqua浸渍40分钟后的固着橡木样品的强度最高提高了约10%。，用Imersol Aqua浸渍40分钟的苏格兰松样品获得了189.111N·m的最低对角线拉伸性能。
