摘要

研究了木材种类、连接技术和粘合剂类型对抗弯性能的影响。测试了480个L形接头试样，包括2种载荷、4种木材、3种接头技术、2种粘合剂和10次重复。标本由苏格兰松、东方山毛榉、橡木和栗子制成。接头技术为榫钉、半搭接和开榫，胶粘剂类型为聚醋酸乙烯酯（PVAc）和聚氨酯（PU）。接头在压缩条件下的抗弯矩范围从具有PVAc的Scotch pine榫钉接头的低60Nm到高达281 N.m w/PVAc的橡木半搭接接头。在张力下加载的接头的抗弯矩范围从带PVAc的苏格兰松榫接头的230 N.m的低值到带PVAc的橡木半搭接接头的917 N.m的最大值。在两种载荷下，带有PVAc的橡木半搭接试样获得了最高的平均弯矩阻力。

Bending moment resistances of L-shaped furniture frame joints under tension and compression loadings.

Effect of wood species, joint techniques, and adhesive type on bending moment resistances were investigated. 480 L-shaped joint specimens were tested including 2 loadings, 4 wood species, 3 joint techniques, 2 adhesives, and 10 replications. Specimens were prepared from Scotch pine, Oriental beech, oak, and chestnut. The joint techniques were dowel, half lap and open mortise and tenon, and type of adhesives were polyvinyl acetate (PVAc) and polyurethane (PU). Bending moment resistance of the joints under compression ranged from a low of 60 Nm for Scotch pine dowel joints with PVAc to oak half lap joints a high of 281 N.m w/PVAc. Bending moment resistance of the joints loaded in tension ranged from a low of 230 N.m for scotch pine dowel joints w/PVAc and to a maximum of 917 N.m for oak half lap joints w/PVAc. Highest average moment resistance was achieved with oak half lap jointed specimens w/PVAc, under both loadings.
