20年来北京地区应用各种类型大型外壁板建造的住宅已达50万平方米以上,近年来发展规模更趋扩大。但在饰面工艺方面虽然作了多种尝试,而能够推广应用的就只有“面向上”(壁板在水平台摸上生产时外表面向上)预制干粘石一种。这种做法的装饰效果与耐久性,经多年实践考验,证明是较好的。存在的问题是:1.如建筑立面需要有线型(腰线、窗套等),就必须在墙板块体成型后二次支模,绑扎钢筋,浇灌混凝土。2.须等拆模后再做预制饰面,占用台座周期长,工序、用工多。3.如果 In the past 20 years, residential buildings of various types of large-scale exterior sidings have been used in the Beijing area for more than 500,000 square meters. In recent years, the scale of development has expanded. However, although various attempts have been made in the decorative arts, the only ones that can be promoted and applied are the “face up” (exterior surface of the siding when the water platform is touched). The decorative effect and durability of this practice proved to be better after many years of practical tests. The existing problems are as follows: 1. If the building facade requires a cable type (waist line, window cover, etc.), it is necessary to mold the wall plate after the secondary molding, tying steel, and pouring concrete. 2. To wait for demoulding before making prefabricated finishes, occupying a long period of pedestal, process, and labor. 3. If
