摘要

摘要: 以毛竹为原料,制备5种密度、2种组坯方式的重组竹材,测定其物理力学性能指标,为重组竹在建筑结构上的应用提供数据支持。结果表明:毛竹基重组竹耐水性能优异,其板材各力学性能均随密度的增加而表现更优;重组竹纵向板的抗弯强度、抗弯弹性模量、顺纹抗压强度、顺纹抗拉强度、水平剪切强度优于纵横板,而纵横板的顺纹抗剪强度、横纹全部抗压强度、横纹局部抗压强度优于纵向板。在实际应用中,可根据产品需求选择板材的密度及组坯方式。

Abstract: Moso bamboo was used as the raw material to produce bamboo scrimber with five different densities and two assembly methods. The physical and mechanical properties of the bamboo scrimber were measured and analyzed to provide data support for the application of bamboo scrimber in building structures. The results showed that bamboo scrimber exhibited excellent water resistance. Overall, the physical and mechanical properties of bamboo scrimber were enhanced with the increase of density. The bending strength, bending modulus, compressive strength parallel to the grain, tensile strength parallel to the grain, and horizontal shear strength were all higher in the longitudinal board compared to the vertical and horizontal board. However, the vertical and horizontal board showed superior shear strength parallel to the grain, total transverse compressive strength, and local transverse compressive strength compared to the longitudinal board. The optimal assembly method and densities should be selected based on specific production requirements.
