【摘要】 自2011年3月15日起,民用建筑外保温材料燃烧性能要求为A级。岩棉板作为无机不燃材料,具有导热系数小、保温性能高、透气性好等优点被广泛应用于外墙外保温建筑工程中。但由于岩棉板密度大,易变形和翘曲,主要在幕墙内使用,其薄抹灰系统在超高层建筑中应用极为少见。结合工程实例,阐述岩棉板薄抹灰系统在超高层建筑外保温中应用所遇到的抗风压、抗剪切、锚栓数量等问题,在理论计算的基础上,分析本系统的技术难点,提出解决办法,通过实体检测和工程验收符合设计要求,为类似工程提供借鉴。更多还原

【Abstract】 Since March 15,2011,the burning performance requirements of civil construction exterior insulation materials should be upto A-level.As a non-combustible inorganic material,the mineral wool panels with small thermal conductivity,high thermal insulation properties,good permeability,etc.are widely used in exterior insulation.However,because of high density,easy to deform and warp,mineral wool panels are mainly used for curtain walls,the thin plaster system applied in super high-rise building is extremely rare.Combining with project examples,based on theoretical calculations,it is described wind pressure,shear,the number of anchor bolts,and other problems when applying the thin plaster miner wool panels in super high-rise building exterior insulation.Then it is analysed the system’s technical difficulties,proposed solutions,testing and project acceptance by entity meet the design requirements,which provides a reference for similar projects.更多还原
