BS EN 14080-2005 木结构.胶合层压板.要求BSEN140802005《木结构——胶合层压板——要求》简介
BSEN140802005是一项由欧洲标准化委员会（CEN）发布的标准，标题为《Timberstructures–Gluedlaminatedtimber–Requirements》，即《木结构——胶合层压板——要求》。该标准主要规定了用于承重结构的胶合层压木材（Glulam）的生产、性能、检验及质量控制等方面的技术要求，适用于建筑和土木工程中使用的结构用胶合木产品。
该标准明确了胶合层压板的定义、分类、材料要求、制造工艺、物理和力学性能、外观质量、尺寸偏差以及标识、包装和运输等方面的内容。其中特别强调了对木材等级、胶合性能、抗弯强度、含水率等关键参数的控制要求，以确保胶合木在结构安全性和耐久性方面满足设计需求。
BSEN140802005还规定了胶合层压板的工厂生产控制（FactoryProductionControl,FPC）体系要求，确保产品在生产过程中持续符合标准规定。此外，标准中也提到了产品认证和测试方法的参考标准，如EN384、EN408等，用于评估材料的基本性能。
该标准适用于欧洲市场内的胶合木生产和使用，是制造商、设计人员、施工方及监管机构的重要技术依据。它不仅保障了胶合木产品的质量一致性，也为木结构建筑的安全性、可持续性提供了规范支持。随着现代木结构建筑的发展输水隧洞施工组织设计，BSEN140802005在推动绿色建筑和低碳建材应用方面发挥着重要作用。
