摘　　要：介绍小径级杉木六棱柱体制材方法特点,并与常规下锯法的出材率进行对比分析。结果表明:六棱柱体制材工艺,可使小径材的出材率达到80%以上;小径级杉木六棱柱体经过进一步的胶拼,可制造大断面六棱柱体集成材,用于木结构梁柱体构件,实现小材大用、劣材优用与提高产品附加值的目的。The authors developed a new sawing method named hexagon-cut technology for small diameter logs. The sawing procedure and key techniques of this new method were described. With this new sawing method （finger joining, composing, and pressing）, small diameter logs could be made into large hexagon glulam beams for wood structural applications. The wood utilization efficiency of hexagon sawing technology can reach up to 80% which is much higher than other conventional sawing methods.
