Unverified隔板厚度直接影响承重：实木/多层板隔板厚度18mm以上抗弯性明显优于15mm以下，长跨度（宽度＞80cm）隔板中间无支撑时应选18-25mm厚板并加中间托89% similarUnverified木制置物架层板厚度应≥15mm（实木或多层实木），＜12mm的密度板长期承重会中间下垂弯曲，且潮湿易崩边86% similarUnverified板材厚度与承重正相关：实木隔板厚度<1.8cm在跨度超过60cm时中间易下垂，长隔板（80cm以上）应选厚度≥2.5cm或中间加装支撑86% similarUnverified板材厚度与跨度存在权衡：18mm实木/多层板跨度可达60cm不明显下垂，但15mm以下薄板长跨度必然弯曲，追求纤薄要缩短单块长度86% similarUnverified实木搁板厚度低于18mm且跨度超过80cm时容易中间下弯变形，长跨度应选25mm以上厚板或在中间加装支撑托架，密度板/刨花板搁板受潮后易膨胀塌陷86% similar
