一般采用平模生产的外墙板,安装后需作饰面处理,不但湿作业量大,装饰效果也不理想。1979年开始,曾采用在墙板钢底模上加焊钢条和用橡胶衬模反打成型外墙板,但这种墙板花纹单一,模板费用较高。为解决上述问题,我公司于1983年开始,先后采用塑料花纹板和玻璃钢花纹板作衬模生产装饰混凝土,取得了花饰变化多、价格低、施工简便的效果。一、工程实例交通部科学研究院科研楼为10层框架结构,带装饰花纹的外墙条板(封二图5)共219块,规格分6270×1800×290mm和6520×1800×290mm两种。采用改性聚丙烯塑料花
The exterior wall panels produced by the flat mold are generally used. After the installation, the finishes are required to be finished. Not only the wet work volume is large, but also the decorative effect is not satisfactory. Since 1979, it has been used to add steel bars to the wall steel bottom molds and back molding the outer wall plates with rubber linings. However, this type of wall plate has a single pattern and the cost of the template is relatively high. In order to solve the above problems, our company began in 1983 and has successively used plastic pattern plates and FRP pattern plates as linings for the production of decorative concrete. It has achieved many changes in floral ornaments, low prices, and simple construction effects. I. Project Example The Scientific Research Building of the Ministry of Science and Technology of the Ministry of Communications is a 10-story frame structure with 219 external wall strips (Front 2 Fig. 5) with decorative patterns. The specifications are 6270×1800×290mm and 6520×1800×290mm. . Modified polypropylene plastic flower
