Bending moment resistance of dowel corner joints in case-type furniture under diagonal compression load

We investigated bending moment resistance under diagonal compression load of comer doweled joints with plywood members. Joint members were made of ll-ply hardwood plywood of 19 mm thickness. Dowels were fabricated of Beech and Hornbeam species. Their diameters （6, 8 and 10 mm） and depths of penetration （9, 13 and 17 ram） in joint members were chosen variables in our experiment. By increasing the connector＇s diameter from 6 to 8 mm, the bending moment resistance under diagonal compressive load was increased, while it decreased when the diameter was increased from 8 to 10 mm. The bending moment re- sistance under diagonal compressive load was increased by increasing the dowel＇s depth of penetration. Joints made with dowels of Beech had higher resistance than dowels of Hornbeam. Highest resisting moment （45.18 N.m） was recorded for joints assembled with 8 mm Beech dowels penetrating 17 mm into joint members Lowest resisting moment （13.35 N.m） was recorded for joints assembled with 6 mm Hornbeam dowels and penetrating 9 mm into joint members.

刨花板包装箱的抗压性能

通过对相同结构的刨花板箱与胶合板箱进行试验分析，认为刨花板箱具有良好的抗压能力，可以在运输包装中作为胶合板箱的替代物。

局部以纸代木包装箱的研究

为缓解木材的供需矛盾,提出了局部以纸代木包装箱的概念。对比了全胶合板包装箱和局部以纸代木包装箱的结构,对局部以纸代木包装箱的力学性能进行了分析。结果表明,在满足应用条件的情况下,局部以纸代木包装箱比全胶合板包装箱更经济实用,具有更广泛的应用潜力。
