本文共分三部分。在第一部分中 ,作者高登·库克指出 ,即使某些可燃夹芯板的耐火性能较差 ,但是它们在日常使用中不失为一种具有诸多优点的结构材料。文中着重讨论了在火灾中保持夹芯板的稳定性和完整性 ,以有利于确保生命财产安全、企业生存和环境保护 ;同时也讨论了夹芯板垮塌将会造成火灾荷载的增加以及烟气的生成和扩散等后果。在第二部分中 ,剖析了内墙和顶棚等处的夹芯板在火灾中过早垮塌的原因 ,并从建筑结构的技术角度 ,提出了一些既能保持优异的日常使用功能 ,又能防止过早垮塌的顶棚和墙面悬挂系统的设计方案。
This article is divided into three parts. In the first part, author Gordon Cook pointed out that even if some combustible sandwich panels have poor fire resistance, they are a structural material with many advantages in daily use. The paper focuses on the stability and integrity of the sandwich panel during fires to ensure the safety of life and property, corporate survival and environmental protection. It also discusses the increase of fire load and smoke caused by the collapse of the sandwich panel. The consequences of generation and proliferation. In the second part, the causes of premature collapse of the sandwich panel at the interior wall and ceiling, etc., were analyzed, and from the technical point of view of the building structure, some of the features that can maintain excellent daily use were proposed and prevented. Prematurely collapsed designs for roof and wall suspension systems.
