This study compared two groups of furniture joints, i.e., a so-called ready-to-assemble (RTA) plastic biscuit joint from Lamello©, while the second group consists of four types of eccentric joints with beech dowels. L-shaped specimens were prepared with the help of the selected joints and a three-layer particleboard with dimensions of 150 × 150 × 400 mm. These L-shaped specimens were tested for bending moment capacity under compression and under tension. Cam joints with wooden dowels can withstand high stress. If Lamello© Bisco P-15 joints are added to the plastic Clamex P-14 joint, this joint will achieve 13% higher values for bending moment capacity under compression and 22% under tension. During testing, the worst result was achieved by the Tenso P-14 joint. The best values achieved during the testing of bending moment capacity under compression and under tension were for an eccentric joint with the use of a metal-capped bolt and Euro screw. This joint achieved 147% higher values for bending moment capacity under compression than a standard eccentric joint with a euro screw bolt and 213% higher values for bending moment capacity under compression than the Lamello© and Clamex P-14 joints. This study aimed to determine how the joints differ, how they behave during testing, and what deformations occur.
本研究比较了两组家具接头，即一种所谓的来自乐木诺（Lamello©）的即装式（RTA）塑料饼干榫，而第二组由四种带山毛榉榫钉的偏心接头组成。借助选定的接头和一块尺寸为150×150×400毫米的三层刨花板制备了L形试件。对这些L形试件进行了压缩和拉伸状态下的弯矩承载能力测试。带木榫钉的凸轮接头能承受高应力。如果将乐木诺（Lamello©）Bisco P - 15接头添加到塑料Clamex P - 14接头上，该接头在压缩状态下的弯矩承载能力值将提高13%，在拉伸状态下提高22%。在测试过程中，Tenso P - 14接头的结果最差。在压缩和拉伸状态下弯矩承载能力测试中取得最佳值的是使用金属帽螺栓和欧式螺丝的偏心接头。该接头在压缩状态下的弯矩承载能力值比使用欧式螺丝螺栓的标准偏心接头高147%，比乐木诺（Lamello©）和Clamex P - 14接头在压缩状态下的弯矩承载能力值高213%。本研究旨在确定接头之间的差异、它们在测试过程中的表现以及会出现哪些变形。
