岩棉薄抹灰外保温系统在京津冀地区抗风压设计研究

依据《岩棉薄抹灰外墙外保温工程技术标准》JGJ/T480-2019等国家规范、标准,以北京市、天津市、石家市城区为例,进行了建筑外墙风荷载标准值和抗风压计算,提出了建筑外墙岩棉薄抹灰外保温粘锚体系在3种基层外墙上不同建筑高度、层数与锚栓数量关系,并对单位面积锚栓数量适用性进行分析,为新建与既有建筑外墙外保温设计提供借鉴。

According to the national norms and standards such as“Technical Standard for Engineering of External Thermal Insulation Composite system based on Rock Wool”JGJ/T480-2019,taking Beijing,Tianjin and Shijiazhuang City as examples,the wind load standard of building exterior wall was carried out.Based on the calculation of wind resistance and wind pressure resistance,the relationship between different building heights,layers and the number of anchor bolts of the external wall rock wool thin plaster external thermal insulation adhesive anchor system on the external walls of the three kinds of bases,and the applicability of the number of anchor bolts per unit area is proposed.The analysis is carried out to provide reference for the external thermal insulation design of new and existing buildings.
