苏联某建筑公司制成了一种浇灌钢筋混凝土预制构件接头的金属模板(见右图)。采用这种模板,不仅灵巧方便,进度也快。它比过去支木模浇灌混凝土能提高劳动生产率约五倍,还能节约大量资金。
A construction company in the Soviet Union made a metal formwork for the joints of reinforced concrete prefabricated components (see right figure). Using this kind of template is not only smart and convenient, but also fast. It can improve labor productivity by about five times as much as it used to cast concrete in the past. It can also save a lot of money.
