摘要

竹材接长处理是制备大尺寸构件的常用方法,为探究竹层板的接长工艺,制备三种竹片接头形式和不同层数的侧压竹层板,分析接长对板材抗弯性能的影响。结果表明:接长会使侧压竹层板的抗弯强度略有降低,但不同接头形式制备侧压竹层板的抗弯性能差异不显著;当接长竹片位于中间层,且板材层数≥3层时,层数变化对侧压竹层板的抗弯性能影响亦不显著。

Abstract

Bending properties of bamboo laminates composed of two layers of unjointed bamboo strips and one layer of lengthwise jointed bamboo strips with 3 kinds of joint types under lateral pressing were tested. Then properties of bamboo laminates composed of different layers unjointed bamboo strips and one layer of lengthened bamboo strips with hook joints were further determined.The results showed that the bending strength of the bamboo laminates with jointed bamboo strips was slightly reduced without significant difference among joint types. When the jointed bamboo strip was laid in the middle of the bamboo laminates composed of more than 3 layers of bamboo strips, layer number of bamboo strips had little effects on bending properties of the bamboo laminates.
