摘　　要：通过比较金属面岩棉夹芯板、金属面单玻镁岩棉夹芯板和金属面双玻镁岩棉夹芯板的抗弯承载力、传热系数和耐火性能,研究探讨了玻镁板对金属面岩棉夹芯板性能的影响。结果表明:与传统的金属面岩棉夹芯板相比,金属面单玻镁岩棉夹芯板的抗弯承载力提高了7.14%,传热系数增大21.18%,耐火极限达61 min,最高温度为136.1℃;金属面双玻镁岩棉夹芯板抗弯承载力提高了32.14%,传热系数增大了30.59%,耐火极限达61 min,最高温度为79.6℃。这表明了在金属面岩棉夹芯板中增加玻镁板会降低整体结构的保温隔热性能,但提高了抗弯承载能力和耐火性能。因此在实际应用中需权衡考虑玻镁板的影响,以实现结构性能的优化设计。This study aimed to examine the impact of glass magnesium boards on the performance of metal faced rock wool sandwich boards.Through comparative experiments focusing on the bending capacity,coefficient of heat transmission,and fire resistance of metal faced rock wool sandwich boards,metal faced single glass magnesium rock wool sandwich board,and metal faced double glass magnesium rock wool sandwich board,the following results were obtained.Compared with the traditional metal faced rock wool sandwich boards,the bending capacity of the metal faced single glass magnesium rock wool sandwich board was increased by 7.14%,the coefficient of heat transmission was raised by 21.18%,and the fire resistance reached 61 minutes with a maximum temperature of 136.1℃.In the case of metal faced double glass magnesium rock wool sandwich board,the bending capacity was enhanced by 32.14%,the coefficient of heat transmission was augmented by 30.59%,and the fire resistance also reached 61 minutes,with a maximum temperature of 79.6℃.This shows that adding glass magnesium board to the metal face rock wool sandwich board will reduce the thermal insulation performance of the whole structure,improve the bending capacity and fire resistance.Therefore,in practical applications,the effect of glass magnesium boards needs to be balanced and considered to achieve the optimized design of structural performance.
