摘要:
 将新采伐（均在纤维饱和点以上）的马尾松（Pinus massoniana）、杉木（Cunninghamia lanceolata）、香樟（Cinnamomum camphora）指榫连接，气干后进行指榫连接处静曲强度、弹性模量、顺纹抗压强度试验，以对应的对照材为参照，探索指榫连接处的有效率。结果表明，3种高含水率木材指榫连接后，指榫连接处会较大幅度降低静曲强度，而同种木材，水平型静曲强度略大于垂直型；指榫连接处静曲强度有效率由高至低依次为：马尾松、杉木、香樟，弹性模量有效率均不<86%；在一定密度范围内，木材的密度越大，指榫连接处顺纹抗压强度有效率越高。
Abstract:
 Finger-jointed wood made of the new logged Pinus massoniana, Cunninghamia lanceolata, and Cinnamomum camphora with moisture content above fiber saturation point were tested for MOR, MOE, compression strength parallel to grain after air-drying. Take wood itself as the control, the efficient rate of the finger-joint location was explored. The results indicated that the MOR at the part of finger-joint location fell after three kinds of high moisture content of wood being finger-jointed, while the MOR of H-type slightly larger than the V-type in the same wood. In descending order of the efficient rate of the finger-joint location, that is P. massoniana, C. lanceolata, and C. camphora, the MOE of the efficient rate of the finger-joint location was not less than 86%. In a certain density range, the greater the density of the wood, the higher the compression strength parallel to grain of the efficient rate of the finger-joint location was.
