摘　　要：以竹束单板层压板为研究对象,分析组坯结构对板材物理力学性能和连接性能的影响。试验结果表明:在组坯层数相同的条件下,随着铺装方向的增多,层压板顺纹的各项力学性能呈下降趋势,采用多向铺装方式的板材的耐水性能低于单一铺装方向的性能,但板材的连接性能得到了提高。因此,实际应用中,在保证竹束单板层合板力学性能达到使用要求的条件下,可以增h层合板组坯方向,改善其连接性能,提高使用的安全性。The effects of lay-up layer numbers on laminated bamboo bundle board’s physical and mechanical properties and connection performance were analyzed. The results show that under the conditions of same layer numbers, along with the increase of the lay-up directions, the bending strength, bending modulus, compression strength and horizontal shear strength of the laminated board showed a downward trend, while using non-single direction lay-up structure, the board’s waterproof property was lower than that of single lay- up board, but the board’s connection performance was risen. Therefore, in the real application, with the condition of guaranteeing the mechanical properties of the board to meet operating requirements, the lay-up directions should be increased to improve the board’s connection performance and to rise the board’s safety.
