举个某个混凝土防火技术规格书里的
Structures and supports to be fireproofed shall be specified on a fireproofing schedule and/or general arrangement drawings denoted by 'F' or 'F*'. In these cases concrete shall be applied to the bottom 2m of columns and lightweight cementitious product applied to all other areas.
要求进行防火保护的结构与支撑应在防火保护计划中给予说明,并/或在总布置图中标注“F”或“F*”。在这些情况中,立柱底部2米处应使用混凝土,其它地方则使用轻型类水泥材料。
