用拉模成型机生产混凝土多孔板等预制构件具有设备投资少、生产效率高、构件质量好、劳动强度低、操作维修方便等优点,适宜于不同规模的构件厂和水泥制品厂在长线台座上生产多孔板、檩条等混凝土建筑构件,有一定的机械化程度,是一项值得推广应用的适用技术。南京市混凝土构件一厂自1983年开始,陆续研制了11.5cm厚5孔板4联、10孔板2联与18cm厚4孔板2联的内振近牵引拉模机,部分代替了简易
The use of a die-casting machine to produce concrete precast elements such as concrete porous plates has the advantages of less equipment investment, high production efficiency, good component quality, low labor intensity, and easy operation and maintenance. It is suitable for component plants and cement products plants of different sizes on long-term pedestals. The production of concrete building elements such as perforated plates and purlins has a certain degree of mechanization. It is an applicable technology that is worthy of promotion and application. Since 1983, Nanjing No. 1 Concrete Component Plant has successively developed an internal vibration near-pull drawing machine with four-in-line, five-hole plates, two-hole plates, and two-hole plates with 18-inch and 4-hole plates, partially replaced by simple ones.
