石灰-水泥系外墙防水装饰砂浆与外墙外保温系统适应性研究

The adaptive research of lime-cement waterproof decorative mortar for exterior wall and exterior insulation system

要使通过化学改性技术研制成功的石灰-水泥系外墙防水装饰砂浆在外墙外保温系统中得到广泛应用,其必须与外墙外保温系统有很好的适应性。通过建立饰面外墙外保温系统受力图,对采用膨胀聚苯板作为高层建筑外墙外保温时,所受水平地震作用、风荷载和两者组合效应及竖直方向受力重力和压剪粘结力分析计算;同时,依据这些计算方法计算了北京市中心高为100 m的高层建筑顶部外墙外保温系统受力情况;计算了外墙饰面为瓷砖、涂料时外墙外保温系统的受力情况,并对其进行比较。结果表明:外墙饰面为石灰-水泥系外墙防水装饰砂浆时应用于高层外墙外保温系统是安全的;所受荷载的大小为瓷砖>石灰-水泥系外墙防水装饰砂浆>涂料,综合比较石灰-水泥系外墙防水装饰砂浆具有优越性。

To make lime-cement waterproof decorative mortar for exterior wall which successes through chemical modification technology to be widely applied in exterior insulation system, it must have good adaptability with exterior insulation system. This paper through establishing force diagram of facing external wall thermal insulation and adopting ESP external wall thermal insulation to be used in high-rise building, analyzing and calculating the earthquake effect by level,wind load and both combination effect and vertical stress gravity and bond force： meanwhile, on the basis of the calculation method to calculate the force of the 100 m-high high-rise building top exterior insulation system in the Beijing center;furthermore,calculating the force of facing external wall thermal insulation when the exterior wall facing is ceramic tile,coating and carrying on the comparison. Results indicate： it is safe when the exterior wall facing is lime-cement waterproof decorative mortar for exterior wall in high-rise exterior insulation system： by the size of the load is for ceramic tile 〉 lime-cement waterproof decorative mortar for exterior wall 〉 coating, in comprehensive comparison, lime-Cement waterproof decorative mortar for exterior wall has superiority.
