日本的混凝土预制构件生产起步较晚,在六十年代初才用倾翻式台座生产构件供建造住宅之用.由于注重实用,各公司根据自己的特点和条件采用各种形式的生产工艺,因此在日本台座法、机组流水法和流水线法三种预制工艺并存.虽然从装备以及机械化程度上各厂差异很大,但都在生产着优质的构件.我们在日本看到的设备最好的工厂是浅沼公司的关东预制厂,它主要采用平模流水生产工艺,该厂有职工95人,其中合同工65人,目前仅维持一班生产,每 Japan’s production of concrete prefabricated components started relatively late. In the early 1960s, they used tilting pedestals to produce components for residential use. Because of their practical importance, companies adopt various forms of production processes according to their own characteristics and conditions. In Japan, there are three types of prefabrication techniques, namely the Taiwan pedestal method, the unit flow method, and the assembly line method. Although there are great differences in the equipment and the degree of mechanization, they are all producing high-quality components. The best plants we have seen in Japan. It is the Kanon prefabrication factory of Asan Corp., which mainly uses flat-molded running water production technology. The factory has 95 employees, of which 65 are contract workers. Currently, only one class of production is maintained.
