摘　　要：装配式建造方式具有绿色环保、节能减排的优点,是建筑业升级转型的必然趋势。针对夹芯保温外挂墙板,通过碳排放系数法,建立了夹芯保温外挂墙板物化阶段的碳排放模型,测算了编号为WQ4-S的墙板在生产阶段、运输阶段和施工阶段的碳排放量。结果表明,墙板在生产阶段产生的碳排放量最高,占比为83.64%,运输阶段和安装阶段占比仅为9.73%和6.64%。而在生产阶段中,原材料消耗对碳排放量贡献最高,达到93.8%。夹芯保温外挂墙板生产阶段中聚乙烯泡沫板消耗、安装阶段上下连接节点的焊接所产生的碳排放总量对整个物化阶段的贡献较小,因此,可不作为碳减排措施的重点。Prefabricated construction methods offer advantages such as green,eco-friendly practices and energy conservation,making them an inevitable trend for the transformation and upgrading of the construction industry.Focusing on sandwich insulated external wall panels,this study establishes a carbon emission model for the materialization stage using the carbon emission coefficient method.The carbon emissions of the WQ4-S wall panel were calculated for the production,transportation,and construction stages.The results indicate that the production stage contributes the highest carbon emissions,accounting for 83.64%,while the transportation and installation stages account for only 9.73% and 6.64%,respectively.Within the production stage,raw material consumption contributes the most to carbon emissions,reaching 93.8%.The carbon emissions from polyethylene foam board consumption during production and welding at connection nodes during installation are minimal,making them less critical for carbon reduction measures.
