摘要

本研究的目的是评估所选参数（如加载类型（压缩和拉伸）、木钉种类和粘合剂类型）对连接刚度的影响。研究使用榉木、橡木和苏格兰松木作为木钉材料，聚醋酸乙烯酯（PVAc）和聚氨酯（PUR）粘合剂作为粘合剂。对制备的 120 块测试样本进行了对角拉伸和压缩弹性刚度测试。结果表明，使用 PVAc 粘合剂粘接的橡木榫接缝在压缩荷载下的平均弹性刚度值最高，达到 656 牛米/拉德。使用 PUR 粘合剂的苏格兰松木榫头在压缩应力下的平均弹性刚度值最低，为 293 牛米/拉德。平均而言，使用 PVAc 粘合剂粘合的橡木榫头的弹性刚度比使用 PUR 粘合剂粘合的苏格兰松木榫头的弹性刚度高 17%。木钉种类和粘合剂类型的影响在统计学上有显著意义。

EFFECT OF MATERIAL, ADHESIVE AND LOADING ON THE STIFFNESS OF WOODEN DOWEL JOINTS

The objective of this study was to evaluate the effects of selected parameters, such as type of loading (compression and tension), the wooden dowel species, and the adhesives type on the joint stiffness. Beech, oak, and Scots pine woods were used as wooden dowel material, and polyvinylacetate (PVAc) and polyurethane (PUR) adhesives were used as adhesive agents. Elastic stiffness on diagonal tension and compression tests were applied on 120 pieces of test samples prepared. The results showed that there was found out that the highest average elastic stiffness value of 656 Nm/rad was achieved in the oak dowel joints bonded with PVAc adhesive under compression loading. The lowest average value of 293 Nm/rad was found in the Scots pine dowel joints subjected to compression stress using PUR adhesive. On average, the elastic stiffness of the oak dowel joints bonded with PVAc adhesive was 17% higher than the elastic stiffness of the Scots pine dowel joints bonded with PUR adhesive. The influence of the wooden dowel species and the adhesive type were found statistically significant.
