This paper presents the fire resistance results of seven full-scale wall assemblies that were conducted at the National Research Council of Canada (NRC) jointly with the North American construction industry and other Canadian government departments. Parameters investigated for protected interior wall assemblies with a single-row of wood studs included: insulation types and mid-height blocking. Parameters investigated for protected interior wall assemblies with a double-row of wood studs on a separate plate included: insulation types, wood studs spacing and mid-height blocking. The impact of the investigated parameters on the fire resistance of wall assemblies is discussed. Results of the parameters studied showed that the installation of mid-height blocking in wall assembly with a single-row of wood stud and filling the wall cavities with cellulose insulation in wall assembly with a double-row of wood studs improved the fire resistance by 10 to 15 minutes, respectively. However, the other parameters studied had improved the fire resistance slightly by up to 6 minutes.

木钉墙组件的耐火性

本文介绍了加拿大国家研究委员会 (NRC) 与北美建筑业和其他加拿大政府部门联合进行的七个全尺寸墙组件的耐火性结果。对具有单排木立柱的受保护内墙组件进行了调查的参数包括：绝缘类型和中高阻挡。对在单独板上具有双排木钉的受保护内墙组件进行的研究参数包括：绝缘类型、木钉间距和中高阻挡。讨论了研究参数对墙组件耐火性的影响。参数研究结果表明，在单排木立柱墙体组合中安装中高挡块，并在双排木立柱墙体组合中用纤维素绝缘填充墙体空腔，可将耐火性能提高 10到 15 分钟，分别。然而，研究的其他参数使耐火性略微提高了 6 分钟。
