建筑物、构筑物外墙粘贴饰面,对建筑墙体既有保护作用,同时又增加建筑物外表美观,体现不同的质感,具有很好的装饰效果。近年来采用中、高档材料作外墙装饰的越来越多,大量瓷砖、劈离砖、玻璃马赛克、人造大理石、花岗石等一些价格昂贵的饰面材料大量用于外墙装饰工程。随着建筑市场对各种饰面材料需求量的不断增加,有的建筑设计与施工对材料选择及使用不尽合理,假冒伪劣建材产品乘虚而入,给装饰工程质量带来许多隐患。尤其我国“三北”地区冬季严寒,深秋和初春冻融频繁,因而造成许多建筑外墙饰面受冻害而脱 The exterior walls of buildings and structures are affixed with veneering, which not only has a protective effect on the building walls, but also increases the appearance of the buildings, reflects different textures, and has a very good decorative effect. In recent years, more and more middle and high-grade materials have been used for exterior wall decoration. A large number of expensive facing materials, such as tiles, split bricks, glass mosaics, artificial marble, and granite, have been used for exterior wall decoration projects. With the increasing demand for various decorative materials in the construction market, some building designs and constructions are not reasonable in terms of material selection and use. Fake and shoddy building materials products take advantage of the fact that they bring many hidden dangers to the quality of decorative works. In particular, the “Three North” region in China suffers from severe cold in winter and frequent freezing and thawing in late autumn and early spring. As a result, many exterior wall claddings are damaged by freezing.
