摘要
提出一种由不同厚度、不同密度的秸秆板胶合而成的秸秆轻质隔墙复合条板。对复合条板保温隔声性能以及耐火性能进行试验研究,分析其作为建筑隔墙应用到实际工程的可行性。试验结果表明:秸秆材料传热系数仅为秸秆混凝土的2.8%,具有良好的保温性能,且保温性能与试件厚度有关,试件厚度越厚,保温效果越好;秸秆材料在中低频段的吸声性能最好,且在测试频率范围内,吸声性能也优于传统建筑材料,表明秸秆材料是良好的建筑隔声构造材料;复合条板两侧分别加12 mm的防火石膏板后的耐火极限超过1.5 h,满足规范规定建筑隔墙耐火极限0.75 h的要求。秸秆轻质隔墙复合条板作为一种新型建筑隔墙,若在实际工程中得到广泛应用,不仅能缓解当前国家所面临的能源问题,也能很大程度上解决废弃秸秆回收利用难题。
This paper proposed a kind of light - weight straw composite panel with different thickness and different densities. The thermal insulation performance, sound absorption performance and the fire resistance were tested in order to analyze the feasibility of the proposed composite panel used as partition. The results showed that the heat transfer coefficient of the straw light - weight partition composite panel was only 2. 8% of the straw concrete panel. Meanwhile the thermal insulation properly was enhanced with the increase of specimen thickness. The test pieces had the best sound absorption performance in middle and low frequency segments. Even in the range of the tested frequency, the sound absorption performance of the proposed composite panel was better than the traditional building materials. When both sides of the composite panel were added by 12 mm gypsum boards, the duration of fire resistance of the pro-posed composite panel was more than 1. 5 h which meets the fire resistance requirement of 0. 75 h for partition. It demonstrated that straw light - weight partition composite panel can be a good kind of building material. Once it was widely used for practical engineer-ing, the proposed composite panel could alleviate the problems of energy and circulating the waste straw.
