中文摘要 | 本研究旨在探討家具用連接螺釘應用在不同木質板材料之接合上,有關組合方法、用釘間距對其彎矩抵抗之影響。結果顯示木心板在平面式接合之彎矩強度以64 mm間距組合為最佳,較最低之128 mm間距條件高出37%,而在側面式接合條件下,以96 mm間距組合為最佳,且為最低之32 mm間距組合之2.29倍。粒片板在平面式接合之彎矩強度在64~128 mm間距條件下,平均較32 mm間距組合高4.2%,而在側面式接合條件下,以128 mm間距組合為最佳,且為最低之32 mm間距組合之3.77倍。中密度纖維板在平面式接合之彎矩強度以128 mm間距條件為最佳,為最低之32 mm間距者之2.31倍,在側面式接合條件則為3.92倍。平均木質板之平面式接合彎矩抵抗能力均為側面式接合之13.8%,而為板式家具結構強度設計之主要考量。 |
英文摘要 | The effects of the types of assemblies and spacing of connecting screws on the bending moment resistance of joints for different wood-based composite panels in the application of the furniture manufacturing were investigated in this study. The results indicated that lumber core plywood members jointed in 64-mm screw spacing with flatwise assembly had better bending moment resistance, 37% higher than those of the weakest assemblies with 128-mm spacing. In the case of the members with edgewise assembly, the specimens assembled in 96-mm screw spacing had the highest bending moment capacity, 2.29 times greater than those of the lowest groups in 32-mm spacing. In the flatwise joints of particleboard members, the average bending moment resistance of joints assembled by using screw spacing among 64~128-mm was 42.8% higher than that assembled in 32-mm spacing. And in the case of edgewise joints, the members assembled with 128-mm screw spacing had the strongest bending moment resistance, 3.77 times greater than those of the weakest group with 32-mm screw spacing. The medium density fiberboard members with flatwise assembly by using 128-mm screw spacing showed the highest in bending moment capacity, 2.31 times greater than those groups assembled with 32-mm spacing, and 3.92 times in the case of edgewise assemblies. In general, the average bending moment capacity of the joints in flatwise assembly was 13.8% of those joints in edgewise assembly for the wood-based composite panels, and may be critical to the structural design for panel type of furniture products. |
