[摘要]介绍了轻型木结构墙面板用结构胶合板抗冲击性能试验的条件、装置和方法,并根据欧洲标准研制了加载装置,研究了结构胶合板在冲击载荷下的结构性能。试验结果表明:同一树种、不同厚度的结构胶合板,厚度越大,抗冲击性能越强;同一树种、同一厚度的结构胶合板,芯板越厚(层数越少),抗冲击性能越好;同一树种的结构胶合板厚度和层数相同时,随着芯板厚度的增加,抗冲击性能有变差的趋势;意杨结构胶合板的抗冲击性能优于桉木结构胶合板。

Abstract:The experimental conditions, equipment and methods of the impact property experiment on structural plywood used in wall panels of light wood frame structure were introduced. According to the requirement of European standard, a loading device was developed to study structural performance of structural plywood under impact load. The experimental results show that for the structural plywood with the same species in different thicknesses, the impact property is in proportional to the thickness. For the structural plywood with the same species and thickness, the impact property is in inverse proportion to the thickness of the core veneer. For the structural plywood with the same thickness and layers of same species, the impact property has tendency to get worse with the thickness increase of the core veneer. Impact property of poplar structure plywood is better than that of eucalyptus plywood.
Keywords:light wood frame structure; wall panel; structural plywood; impact property
