摘　　要：以12、18mm2种厚度竹篾胶合板覆板的均布载荷性能为研究对象,考察了12mm竹篾胶合板用作轻型木结构房屋屋面板的均布载荷性能及18mm竹篾胶合板用作楼面板的均布载荷性能。结果表明:12mm竹篾胶合板在均布载荷作用下,其挠度为1.524mm,满足结构用胶合板覆板屋面板的挠度限值;18mm竹篾胶合板在均布载荷作用下,干态条件下挠度满足标准要求,而湿态重干条件下的挠度为2.509mm,不满足结构用胶合板覆板楼面板的挠度限值。Uniform load performance of 12mm and 18ram sheathing of sliver plybamboo which were used for roof and floor panel were respectively studied. The results showed that deflection of 12mm sliver plybamboo is 1.524mm at uniform load, and this meets deflection limits of roof sheathing of structural plywood. Deflection of 18ram sliver plyhamboo under the condition of dry meets standard requirements when at uniform load, and the deflection is 2.509mm under sihgle moisture cycle, and this cannot meet deflection limits of sheathing panel of structural plywood.
