细木工板横向静曲强度测试中加载受力位置与最大载荷关系探讨

Analysis of Loading Force Point and Maximum Load of Blockboard

为探讨在细木工板横向静曲强度检测中加载辊不同施加压力位置对试件最大载荷的影响,依据GB/T5849—2016《细木工板》中的静曲强度和弹性模量测定方法,进行了对比试验。结果显示,加荷辊施加压力在拼缝隙处的测试数据比避开芯条侧面缝隙加载方式测得的最大载荷偏低约14%,从而要求相关检测人员操作时需要严格按照相关标准要求进行试验。

This study examines the effect of different pressure application points on the maximum load of blockboard specimens during transverse static bending strength tests using loading rollers:Conducted in accordance with the GB/T 5849-2016 Blockboard standard,the comparative tests revealed that applying pressure at the joint gap resulted in a maximum load approximately 10%lower than when pressure was applied away from the core strip's side gap.These results underscore the importance of strict adherence to standard testing protocols.
